Description
Background of the Invention
The present invention relates to a coin receiving and discharging apparatus equipped in a vending machine, a money exchanging machine, a money automatically-discharging machine, or the like, and particularly relates to a small-sized coin receiving and discharging apparatus having two coin cases for accepting coins, which are the same or different in kind from each other, and for selectively discharging the coins from the coin cases.
An apparatus provided with a plurality of coin tubes so as to selectively discharge coins from the coin tubes is disclosed, for example, in U.S. Pat. Nos. 3,690,332 and 4,121,603 issued on Sept. 12, 1972 and Oct. 24, 1978 respectively, and in Japanese Patent Post-examination Publication No. 57-19833 published on Apr. 24, 1982. In such a conventional apparatus, however, the coin tubes are disposed side by side in the left and right direction with respect to the front surface having a coin discharge opening. Accordingly, when the apparatus is installed in a place, a relatively wide use frontage is required in the place, while the depth of the place can not be effectively used when the place has much room in depth. Prior to the present invention, Osamu KOBAYASHI, one of the inventors of this application invented a coin discharging apparatus as described hereunder and disclosed the apparatus in the above-mentioned Japanese Patent Post-examination Publication No. 57-19833. The apparatus according to the prior invention has a mechanism in which there are provided two coin tubes disposed side by side in the left and right direction, and a horizontally pivotally movable fan-shaped plate disposed under the lower ends of the coin tubes and having two coin accepting holes each for accepting one coin, whereby the plate is pivotally reciprocated by the operation of a solenoid so that the plate receives coins alternately from the coin tubes and succeedingly discharges the received coins through a single coin passing hole provided under the plate. However, the apparatus is configured such that the fan-shaped plate is horizontally pivotably moved over the two coin tubes disposed side by side in the left and right direction, and a large space is therefore required. Thus, the apparatus is disadvantageous in that not only the apparatus becomes large in size but in the case where the apparatus is mounted on the side surface of a coin selecting apparatus, a vending machine, or the like, having sufficient room particularly in depth, the depth of the coin selecting apparatus, the vending machine, or the like can not be used effectively.
Summary of the Invention
It is an object of the present invention to provide a coin receiving and discharging apparatus in which the disadvantages of the aforementioned prior art apparatus is eliminated to make the apparatus small in size.
It is another object of the present invention to provide novel coin introducing means for inserting coins respectively into two coin cases arranged side by side in the front and rear direction of the apparatus.
It is a further object of the present invention to provide novel means for selectively discharging coins in various manners from the two coin cases arranged side by side in the front and rear direction of the apparatus.
In order to achieve the above objects, according to the present invention, the coin receiving and discharging apparatus constituted by a coin receiving unit and a coin discharging unit removably connected to each other has the following configuration.
That is, the coin receiving unit is constituted by: a housing vertically extending in the form of a hollow square pillar and having a front side, a rear side and left and right sides, the housing being longer in depth than in width; front and rear coin cases formed by dividing the interior of the housing with a partition plate extending in parallel with the front and rear sides of the housing for receiving coins in a horizontally piled state, the front and rear coin cases having respectively open lower ends positioned in one and the same horizontal plane; a pair of coin inserting slits formed in an upper portion of the front side of the housing; coin introducing means provided in the housing for selectively introducing coins from the respective coin inserting slits into the front coin case and the rear coin case; and coin guiding means provided under the front and rear coin cases for selectively accepting at least one of two coins lying in the respective lowest layers in the front and rear coin cases and successively dropping the at least one coin into the coin discharging unit. The coin guiding means is constituted by a plate-like guide member horizontally secured to the respective open lower ends of the front and rear coin cases and having a coin passing hole the diameter of which is not less than a coin diameter and the central axis of which is positioned just under a lower end of the partition plate, and a sliding plate mounted on an upper surface of the guide member so as to be movable forward/rearward between the open lower ends and the guide member and having a coin accepting hole which has a diameter not less than the coin diameter and an edge thickness substantially equal to a coin thickness and traverses right over the coin passing hole of the guide member when the sliding plate is moved, the sliding plate having a socket formed in a lower surface thereof to open downward.
The coin discharging unit is constituted by a coin discharge section detachably disposed under the coin guiding means of the coin receiving unit for discharging a coin dropped by the coin guiding means to the exterior of the coin discharging unit, driving means detachably engaged with the socket of the sliding plate of the coin guiding means for horizontally reciprocating the sliding plate forward and rearward, and controlling means for controlling the driving means so that the sliding plate is actuated to operate, to reciprocate and to stop in accordance with a selected coin discharge manner.
According to the present invention, coins can be inserted into the two coin cases disposed side by side in the front and rear direction without providing any structure portion projected outside from the two coin cases, and the coins are guided from the coin cases to the coin discharge section by the sliding plate arranged to reciprocate forward and rearward within the range just under the coin cases, so that it is possible to effectively receive and discharge coins in a small space. Accordingly, the apparatus can be small-sized, and in the case where the apparatus is mounted on the side surface of a coin selecting apparatus having sufficient room particularly in depth, the depth of the coin selecting apparatus can used effectively. Further, the operation of the sliding plate can be divided into forward-half portion reciprocating movement in connection with the front coin case and rearward-half portion reciprocating movement in connection with the rear coin case, or can be made to be reciprocating movement over the front and rear coin cases, so that the discharge of coins can be performed in various manners.

Detailed Description of Preferred Embodiment
Referring to FIGS. 1 through 5 and FIGS. 6a through 6f, an embodiment of the coin receiving and discharging apparatus according to the present invention will be described. FIG. 1 shows the whole of the coin receiving and discharging apparatus of the embodiment. The apparatus is constituted by a coin receiving unit 3 and a coin discharging unit 20 which will be described in detail hereunder.
Referring to FIGS. 1 and 2, the coin receiving unit 3 is constituted by: a vertically-extending hollow square pillar housing 11 having a front side, a rear side, and left and right sides, the housing being longer in depth than in width; front and rear coin cases 2a and 2b which are formed by dividing the interior of the housing 11 with a partition plate 12 extending in parallel with the front and rear sides of the housing 11, the front and rear coin cases 2a and 2b having opening lower ends thereof positioned in one and the same horizontal plane; a coin inlet 13 constituted by a pair of coin inserting slits formed in an upper portion of the front side of the housing 11 so as to communicate with the front and rear coin cases 2a and 2b respectively; and coin guiding means 7 provided under the open lower ends of the coin cases 2a and 2b for selectively accepting the coins lying in the respective coin cases 2a and 2b and dropping the coins into the coin discharging unit 20.
The same kind or different kinds of coins C.sub.1 and C.sub.2 inserted from the coin inlet u3 are introduced into the front and rear coin cases 2a and 2b respectively and stored in the horizontally piled state. As coin introducing means, in the embodiment, the coin inlet 13 is constituted by a vertical slit for a coin-C.sub.1 inlet 13a and a horizontal slit for a coin-C.sub.2 inlet 13b which are combined to form a T-shaped coin inlet. A guide plate 14 inclined from a lower edge of the horizontal slit 13b downward to the upper end of the partition plate 12 is provided so as to cover the upper end of the front coin case 2a. A slit 15 elongated from the slit 13a to the upper end of the partition plate 12 is formed in the guide plate 14 so that the coin C.sub.1 is vertically inserted from the vertical slit 13a into the front coin case 2a. The coin C.sub.2 is slid from the slit 13b on the guide plate 14 and stored in the rear coin case 2b. FIGS. 3 and 4 show this novel structure in detail and the state where coins are being inserted.
Referring to FIGS. 1 and 5, the coin guiding means 7 is constituted by a substantially plane-like guide member 18 and a sliding plate 4 slidably mounted on the upper surface of the guide member 18.
The guide member 18 is constituted by a quadrangular plate 16 horizontally fixed to the respective open lower ends of the front and rear coin cases 2a and 2b, and a coin passing hole 17 formed in the central portion of the quadrangular plate 16 and having a hole diameter which is substantially equal to or a little larger than the diameter of the coins. The coin passing hole 17 is formed so that the central axis of the coin passing hole 17 is just under the lower end of the partition plate 12. Further, a guide slit 21 is formed in the rear portion of the plate 16 so that the slit 21 communicates at its one end with the coin passing hole 17, extends along a longitudinal central line of the quadrangular plate 16, and opens at its other end in the rear edge of the plate 16. A rear connecting strip 22 is provided on the rear upper surface of the plate 16 so as to straddle the guide slit 21.
The sliding plate 4 has a thickness substantially equal to the thickness of one coin and is constituted by a base plate 23 and a coin accepting hole 5. The base plate 23 is constituted by a wide front portion 23a and a narrow rear portion 23b and mounted on the plate 16 of the guide member 18 so as to be slidable forward/rearward between the plate 16 and the respective open lower ends of the front and rear coin cases 2a and 2b. The coin accepting hole 5 is formed in the central portion of the wide front portion 23a so as to have a diameter sufficient to horizontally accept one coin and so as to traverse just above the coin passing hole 17 of the guide member 18 as the base plate 23 is moved. An engage member 24 elongated in the front and rear direction is provided on the central portion of the lower surface of the narrow rear portion 23b of the plate 23 so that the engage member 24 is slidably fitted in and passed through the guide sit 21 of the guide member 18 so as to project downward below the plate 16. The front end of the engage member 24 is formed at its lower portion into a protrusion 25 so as to slightly face a portion just under the coin accepting hole 5, and also it is formed at its upper portion into a step 25b having a surface curved along the circumference of the coin accepting hole 5 adjacent to the protrusion 25. The protrusion 25 is formed so as to have an inclined surface 25a inclined forward downward from the lower edge of the step 25b. Further, a pair of elongated support strips 26 and 26 are secured to the opposite sides of the engage member 24 so as to slidably sandwich the plate 16 of the guide member 18 between the support strips 26 and 26 and the lower surface of the narrow rear portion 23b of the sliding plate 4. A socket 27 opened downward is formed on the rear lower surface of the engage member 24 so as to be removably and slidably engaged with a hemispherical upper end 31 of a pivotal lever 8 which will be described later.
Referring to FIG. 1, the coin discharging unit 20 is constituted by: a coin discharge section 6 for accepting the coins which are taken out from the coin cases 2a and 2b and dropped down by the operation of the coin guiding means 7 of the coin receiving unit 3 and for discharging the coins to the exterior of the coin discharging unit; driving means detachably engaged with the socket 27 of the sliding plate 4 of the coin guiding means 7 for horizontally reciprocating the sliding plate 4; and controlling means for controlling the operation of the driving means so that the sliding plate 4 of the coin guiding means 7 is moved to accept at least one of the coins in the front and rear coin cases 2a and 2b into the coin accepting hole 5 and successively to drop the coin into the coin discharge section 6 through the coin passing hole 17 at each reciprocation of the sliding plate 4. The coin discharge section 6 has a coin discharge opening 19 provided in the front surface of the coin discharge section 6 for taking out coins to the exterior, and a coin guiding surface 6a so that the coins dropped from the coin guiding means 7 can slide down to the coin discharge opening 19.
The driving means is constituted by a driving motor 37, a rotary disc 34 rotated by the motor 37 through a gearing mechanism 36 operatively connected to the motor 37, and a movement converting mechanism 9 for converting the rotation of the rotary disc 34 into the horizontal linear movement of the sliding plate 4 of the coin guiding means 7. The movement converting mechanism 9 is constituted by: a crank pin 33 on the circumferential portion of the rotary disc 34; a pivotal lever 8 substantially vertically extending adjacent to and in parallel with the rotary disc 34 and having a lower end pivotably connected to a pivot shaft 30 projected inward from the side rear lower portion of a casing 29 surrounding the coin discharging unit 20 and the hemispherical upper end 31 engaged with the socket 27 of the engage member 24 as described above; and a slide slot 32 formed longitudinally in the middle portion of the pivotal lever 8 so that the slide slot 32 receives the crank pin 33 so as to slidably engage with the crank pin 33. In such a configuration, when the rotary disc 34 is rotated forward or reversely, the pivotal lever 8 is inclined forward or rearward around the pivot shaft 30 as the crank pin 33 moves circumferentially, so that the sliding plate 4 is moved horizontally forward/rearward.
Referring to FIGS. 1, 6a and 6b, the controlling means is constituted by a first switch S.sub.1 actuated when the coin accepting hole 5 being moved is located just under the coin case 2a so as to accept a coin from the coin case 2a and having means for making a first signal corresponding to this actuation; a second switch S.sub.2 actuated when the coin accepting hole 5 being moved is located just under the coin case 2b so as to accept a coin from the coin case 2b and having means for making a second signal corresponding to this actuation; a third switch S.sub.3 actuated whenever one of the coins C.sub.1 and C.sub.2 received in the coin accepting hole 5 being moved is dropped into the coin discharge section 6 through the coin passing hole 17 and having means for making a third signal corresponding to this drop; and a controller 35 for receiving the first, second and third signals and controlling the operation of the motor 37 in response to each of the first second and third signals. The controller 35 operates such that (i) the controller 35 receives a coin discharging command signal to start the motor to rotate forward or reversely when the coin guiding means 7 is in a standby state as shown in FIG. 7, that is, when the sliding plate 4 is in its non-play position, (ii) the controller 35 receives the signals produced from the first and second switches S.sub.1 and S.sub.2 to relatively reverse the rotation of the motor 37 (that is, to move the sliding plate 4 reversely to the direction so far, and (iii) the controller 35 counts the number of drops of the coins corresponding to an amount of predetermined discharge money in response to the third signal and then stops the rotation of the motor 37 when the sliding plate 4 has returned to the non-play position.
In the embodiment, the reference numerals 39 and 40 designate a carrying handle and a viewing window for checking up the state of piling of coins in the coin cases, respectively. As shown in FIG. 2, it is convenient that the upper left or right half portion of the housing 11 is pivoted at the pivot pin 38 so as to make the upper left or right half portion openable as shown by a phantom line in the drawing.
In the embodiment of the apparatus having a configuration as described above, however, it has been found there exists the following disadvantage when the coin receiving unit 3 is separated from the coin discharging unit 20 to repair the apparatus or to adjust the coin discharging function. That is, if the units 3 and 20 are separated from each other, the sliding plate 4 is disengaged from the pivotal lever 8 of the driving means so that the sliding plate 4 becomes movable forward/rearward freely. As a result, coins in the coin cases 2a and 2b are allowed to accidentally drop through the coin accepting hole 5 and the coin passing hole 17 as the sliding plate 4 moves. Further, when the units 3 and 20 are connected to each other again, the position of the sliding plate 4 is uncertain so that it is troublesome to make the sliding plate 4 engage with the pivotal lever 8.
In order to eliminate the above disadvantage, the inventors of this application have improved the coin guiding means 7 in a manner so that there is provided locking means 42 for releasably locking the sliding plate 4 at the non-play position shown in FIG. 1 when the units 3 and 20 are separated from each other.
Referring to FIGS. 7, 8a and 8b, the locking means 42 is constituted by: a concavely notched portion 41 formed in the longitudinal free edge of one of the pair of support strips 26 of the engage member 24 of the sliding plate 4; a downward open recess 43 formed, adjacent to the notched portion 41, in the lower surface of the quadrangular plate 16 of the guide member 18; a guide shaft 44 projected downward from the bottom portion of the recess 43 so as to define an annular space between the inner circumferential surface of the recess 43 and the guide shaft 44; a sleeve 45 surrounding the guide shaft 44 so as to vertically movable along the guide shaft 44, the sleeve 45 having an upper end surface through which the guide shaft 44 slidably penetrates and a free lower end which is in contact with the upper surface of the coin discharging unit 20 so as to be urged by the latter; spring means 46 inserted between the bottom portion of the recess 43 and the upper end surface of the sleeve 45 so as to urge the upper end surface of the sleeve 45 against a sleeve stopper 47 fixed on the free lower end of the guide shaft 44; and a hemicircular protrusion 45a projected from the upper end surface of the sleeve 45 toward the inner circumference of the recess 43 so as to define a gap between the protrusion 45a and the inner circumference of the recess 43. In the state in which the coin receiving unit 3 is mounted on the coin discharging unit 20 as shown in FIG. 8b, the sleeve 45 is pressed up against the spring means 46, so that the hemicircular protrusion 45a exists inside the recess 43 and the sliding plate 4 is moved forward/rearward by the driving means. When the units 3 and 20 are separated from each other as shown in FIG. 8a, on the contrary, the sleeve 45 is pressed down by the spring means 46, so that the protrusion 45a is frictionally engaged with the notched portion 41 of the support strip 26 and thereby the sliding plate 4 is locked at the non-play position.
Referring to FIG. 1 and FIGS. 6a through 6f, the coin discharging operation mechanism of the apparatus of the embodiment will be described hereunder. When the apparatus is in the standby state for coin discharge as shown in FIG. 1, the pivotal lever 8 is substantially vertical and the coin accepting hole 5 of the sliding plate 4 is located so as to coaxially agree with the coin passing hole 17 of the guide member 18 opened over the respective open lower ends of the coin cases 2a and 2b aligned side by side in the forward/rearward direction, the coins in the coin cases 2a and 2b being laid on the upper surface of the sliding plate 4.
For example, when the coins C.sub.1 stored in the front coin case 2a are to be discharged in the above-mentioned state, a coin discharging command signal is applied to the controller 35 to start the motor 37, the rotary disc 34 is rotated through the gearing mechanism 36 counterclockwise by a predetermined angle in FIG. 1, and the pivotal lever 8 is inclined forward through the engagement between the slide slot 32 and the crank pin 33 as shown in FIG. 6a. As the pivotal lever 8 is inclined, the sliding plate 4 is moved forward through the engagement between the upper end 31 of the pivotal lever 8 and the socket 27 of the sliding plate 4. The coin accepting hole 5 of the sliding plate 4 accepts one of the coins C.sub.1 when the coin accepting hole 5 has come to completely communicate with the open lower end of the front coin case 2a as shown in FIG. 6b. At the same time, the first switch S.sub.1 sends the first signal to the controller 35, for example, in response to the operation of the rotary disc 34, and the controller 35 makes the motor 37 rotate reversely to the direction so far in response to the signal so as to rotate the rotary disc 34 clockwise by the predetermined angle, whereby the sliding plate 4 is retreated to return to the initial stand-by position as shown in FIG. 6c. Upon completion of counting a predetermined number of drops of the coins in response to the third signal produced from the third switch S.sub.3, the controller 35 stops the rotation of the motor 37. On the other hand, in the returning process of the sliding plate 4, one coin C.sub.1 captured into the coin accepting hole 5 is dropped into the coin passing hole 17 of the guide member 18 and is succeedingly guided from the coin passing hole 17 into the coin discharge opening 19 while being guided by the inclined surface 25a of the protrusion 25 of the engage member 24 and the coin guiding surface 6a provided in the coin discharge section 6 as shown by a phantom line in FIG. 6c. The operation described above is repeated so that the coins C.sub.1 stored in the front coin case 2a are succeedingly discharged.
When the coins C.sub.2 stored in the rear coin case 2b are to be discharged, in the coin discharge stand-by state described above (see FIG. 1), the rotary disc 34 is rotated clockwise by a predetermined angle through the operation of the controller 35 and the motor 37, so that the pivotal lever 8 is inclined rearward, as shown in FIG. 6d, to thereby move the sliding plate 4 rearward. Further, when the sliding plate 4 is moved rearward to the position shown in FIG. 6e, the coin accepting hole 5 accepts one coin C.sub.2 from the rear coin case 2b. At the same time, the second switch S.sub.2 produces the second signal so that the controller 35 makes the motor 37 rotate reversely in response to the signal so as to rotate the rotary disc 34 counterclockwise by the predetermined angle. As a result, the sliding plate 4 is advanced to return into the initial stand-by state. In the returning process, the coin C.sub.2 captured in the coin accepting hole 5 is passed through the coin passing hole 17 of the guide member 18 to reach the discharge opening 19 of the coin discharge section 6 as shown by a phantom line in FIG. 6f. When the coin C.sub.2 has reached the coin discharge opening 19, the third switch S.sub.3 produces a third signal. After the controller 35 has counted a predetermined number of drops of the coins in response to the third signal produced from the third switch S.sub.3, and when the sliding plate 4 has returned to the initial stand-by state, controller 35 stops the rotation of the motor 37. The operation described above is repeated so that the coins C.sub.2 stored in the rear coin case 2b are succeedingly discharged.
In the manner as described above, the coins C.sub.1 stored in the front coin case 2a and the coins C.sub.2 stored in the rear coin case 2b can be selectively discharged through the forward-half reciprocating operation of the sliding plate 4 and through the rearward-half reciprocating operation of the sliding plate 4, respectively. Accordingly, the structure of the apparatus is effective in the case where the coins C.sub.1 and the coins C.sub.2 are made different from each other in kind of money, and in the case where the coins C.sub.1 and C.sub.2 are the same in kind of money, and, after completion of preceding coin discharge from any one of the coin cases 2a and 2b, the coin discharge path is changed over so that coins are supplemented into the one coin case while coin discharge operation is carried out from the other coin case, and so on.
Alternatively, in place of the operation described above, the driving of the motor 37 may be controlled so that the coin accepting hole 5 is reciprocatively operated over the front and rear coin cases 2a and 2b without dividing the operation into the forward-half reciprocation and the rearward-half reciprocation as described above. In this case, the coins stored in the coin cases 2a and 2b are discharged alternately from the coin cases 2a and 2b. Alternatively, the motor may be continuously rotated in one and the same direction so that the rotary disc 34 is rotated only in one direction so as to discharge coins alternately from the coin cases 2a and 2b. That is, for example, if the rotary disc 34 is made to rotate counterclockwise from the coin discharge stand-by state shown in FIG. 1, the sliding plate 4 is shifted from the state shown in FIG. 1 successively to the states shown in FIGS. 6a, 6b, and 6c so that one of the coins C.sub.1 stored in the front coin case 2 a is first discharged, and succeedingly the sliding plate 4 is shifted successively to the states shown in FIGS. 6d, 6e, and 6f so as to return to the state in FIG. 1 again so that one of the coins C.sub.2 stored in the rear coin case 2b is discharged. Thus, two coins can be discharged at each reciprocation of the sliding plate 4 through each rotation of the rotary disc 34.
This invention may be practiced or embodied in still other ways without departing from the spirit or essential character thereof. For instance, while in the illustrated preferred embodiments the front and rear coin cases are shaped to have a quadrangular horizontal cross-section and provided with means for selectively introducing coins into the two coin cases, the respective coin cases may alternately be shaped in the form of a cylindrical tube or a hollow square pillar either of which has an upper end for inserting therethrough the coins into the tube or the pillar. In this modified form, the invention pertains to a coin discharging apparatus simply provided with front and rear coin cases rather than a coin receiving and discharging apparatus as disclosed hereinbefore. As a matter of course, the coin discharging apparatus according to the invention comprises the coin guiding means, the coin discharge section, the driving means and the controlling means all of which are disclosed in the foregoing. The preferred embodiments described herein are therefore illustrative and not restrictive, the scope of the invention being indicated by the appended claims and all variations which come within the meaning of the claims are intended to be embraced therein.
