Description
Background of the Invention
[0001] 1. Field of the Invention
[0002] This invention relates to slot machines, and in particular to a continuous play slot machine and retrofit kit.
[0003] 2. Background of the Invention
[0004] Slot machines are a type of gaming device which typically feature a handle or a switch button which actuates a reel spinning mechanism. The reel spinning mechanism spins a number of reels upon which illustrations are printed. When the reels stop, if a winning combination of illustrations is visible through a slot machine window, then the slot machine pays winnings. The slot machine winnings are payable either via coins counted into a slot machine coin tray, or by an attendant if the winnings amount is high enough.
[0005] Hours of entertaining and potentially profitable play can be derived from slot machines. Unfortunately, conventional slot machines require a separate actuation of the reel spinning mechanism every time a new play is to be initiated. Thus an individual gamer is hard-pressed to play two or more machines simultaneously. In addition, if the gamer wishes take a drink, converse with bystanders, light a cigarette, etc., then he must cease play while engaging in such activity.
[0006] Many individuals who play slot machines are older individuals, who become fatigued having to repeatedly pull a lever or depress a spin switch over a lengthy period of time. In addition, handicapped individuals may find play difficult or impossible where a handle or switch must repeatedly be actuated. Even healthy individuals may become fatigued after hours of play.
[0007] Thus, it would be advantageous to provide a slot machine which is capable of playing continuously by itself, without input from a gamer, so long as available credit remains, and which ceases play when winnings are disbursed or when its credit has been depleted. Simplicity and retrofittability would be desirable attributes of such a slot machine control system.
Existing Designs
[0008] A number of patents have issued for slot machines which are automated to a greater or lesser degree. Walker et al. received U.S. Pats. No. 6,012,983 and 6,244,957 for an automated gaming device. These patents taught slot machines which suffered from a number of drawbacks. Considerable data had to be entered in order to use them, and a credit card was required. These patents taught a remote communications device which was to be carried by individuals using the slot machines. Thus, complexity and cost rendered these designs undesirable, and retrofit cost would have been high.
[0009] U.S. Pat. No. 5,067,712 issued to Georgilas for a slot machine design which provided an extra play if a gamer did not achieve a winning combination during the first reel spin. U.S. Pat. No. 5,067,524 was issued to Inoue for a slot machine which afforded a special reel movement upon a gamer achieving a winning combination, to help inexperienced garners recognize winning combinations. While these designs were interesting, they did not provide for continuous play of a slot machine limited only by the remaining credit and commands from the gamer.
[0010] Takemoto et al. were granted U.S. Pat. No. 5,813,511 for a slot machine which would spin its reels when a pre-determined number of coins was inserted into its coin slot. While this design eliminated the need for a handle or switch to actuate the reel spinning mechanism, it still required the insertion of a pre-determined number of coins to spin its reels.
[0011] DeMar et al. were granted U.S. Pat. No. 6,270,410 for a slot machine remote control which operated one or more slot machines remotely. This scheme required a remote control or computer external to the slot machine(s) to be controlled, and suffered from the drawbacks of complexity and cost.
Summary of the Invention
[0012] Accordingly, it is an object of the present invention to provide a continuous play slot machine which, when commanded by a gamer, will play continuously without the gamer having to initiate play each time the reels are to be spun. Design features allowing this object to be accomplished include a continuous play switch electrically connected to a timing and logic controller. Advantages associated with the accomplishment of this object include the ability of a gamer to take a drink, converse with bystanders, light a cigarette, etc., without having to interrupt his slot machine play. Additional advantage associated with the accomplishment of this object is maximization of the efficiency of use of the slot machine, and enhancement of the gambling house's profits, as well as reduction of fatigue in older, handicapped and even healthy players.
[0013] It is another object of the present invention to provide a continuous play slot machine which delays each successive play by a predetermined time lapse. Design features allowing this object to be accomplished include a timing and logic controller which controls reel spin. A benefit associated with the accomplishment of this object is the ability of a gamer to cease the continuous play function at any time he desires by re-actuating the continuous play switch.
[0014] It is still another object of this invention to provide a continuous play slot machine which ceases continuous play when the reels stop at a winning combination. Design features allowing this object to be accomplished include a timing and logic controller which controls reel spin. An advantage associated with the realization of this object is the ability for a gamer to take advantage of the stopped play to collect his winnings upon achieving a winning reel combination.
[0015] It is another object of the present invention to provide a continuous play slot machine which ceases continuous play upon exhaustion of credit on the machine. Design features allowing this object to be accomplished include a timing and logic controller which controls reel spin. A benefit associated with the accomplishment of this object is control of the slot machine to avoid deficit play to the detriment of the gaming house.
[0016] It is still another object of this invention to provide a continuous play kit which can easily be retrofitted into existing slot machines. Design features enabling the accomplishment of this object include a continuous play kit incorporating a continuous play switch and a timing and logic controller. Advantages associated with the realization of this object include reduced installation cost and hence increased availability to gaming houses, and their consequent improved profits and customer satisfaction.
Brief Description of the Drawings
[0017] The invention, together with the other objects, features, aspects and advantages thereof will be more clearly understood from the following in conjunction with the accompanying drawings.
[0018] Three sheets of drawings are provided. Sheet one contains FIG. 1 . Sheet two contains FIG. 2 . Sheet three contains FIG. 3 .
[0019] FIG. 1 is a front isometric view of a continuous play slot machine.
[0020] FIG. 2 is a schematic view of a continues play slot machine.
[0021] FIG. 3 is a schematic diagram of the timing and logic controller.
[0022] FIG. 4 is a schematic diagram of an alternate embodiment timing and logic controller.
Detailed Description of the Preferred Embodiment
[0023] FIG. 1 is a front isometric view of continuous play slot machine 2. Continuous play slot machine 2 comprises reels 4, spin reels switch 6 and continuous play switch 8. During conventional, manual play, a gamer would deposit sufficient money to play at least once, and then actuate spin reels switch 6 in order to cause a reel spinning mechanism to spin reels 4. If reels 4 stop at a winning combination, winnings are dispensed into winnings tray 5, or the gamer receives a hand pay. If enough credit remains on the machine for another play the gamer can initiate same by again actuating spin reels switch 6.
[0024] Continuous play can be initiated on continuous play slot machine 2 by actuating continuous play switch 8. FIG. 2 is a schematic view of continuous play slot machine 2. As may be observed, timing and logic controller 10 is electrically connected to continuous play switch 8, as well as to a reel spinning mechanism for reels 4, a credit sensor, and a winning combination sensor (reel spinning mechanism and sensors not depicted).
[0025] FIG. 3 is a schematic diagram of timing and logic controller 10. Actuation of continuous play switch 8 engages timing and logic controller 10, which initially checks that enough credit for play remains, and if so instructs reel spinning mechanism to spin reels 4. After reels 4 stop, any win credit is recorded. Timing and logic controller 10 then waits a predetermined time delay and then determines if sufficient credit for play remains on continuous play slot machine 2. If no, continuous play slot machine 2 reverts to manual play, and additional credit must be supplied prior to any further play. If enough credit for play remains, timing and logic controller 10 again directs reel spinning mechanism to spin reels 4, and the above described decision tree repeats.
[0026] An alternate embodiment timing and logic controller 10 is depicted in FIG. 4 . In the alternate embodiment, when reels 4 stop, if a winning combination is achieved continuous play slot machine 2 reverts to manual play and payment is made to the gamer. If continuous play is subsequently desired, continuous play switch 8 is then re-actuated. If no winning combination is achieved, timing and logic controller 10 then waits a preset time interval and then determines if sufficient credit for play remains on continuous play slot machine 2. If no, continuous play slot machine 2 reverts to manual play, and additional credit must be supplied prior to any further play. If enough credit for play remains, timing and logic controller 10 again directs reel spinning mechanism to spin reels 4, and the above described decision tree repeats.
[0027] Continuous play slot machine 2 may be manually directed to return to manual play mode at any time by simply re-actuating continuous play switch 8. Thus, successively actuating continuous play switch 8 has the effect of toggling continuous play slot machine 2 between continuous play and manual play.
[0028] A continuous play retrofit kit is also intended to be within the scope of the present disclosure. The continuous play retrofit kit comprises timing and logic controller 10 connected to continuous play switch 8. The retrofit installation includes the steps of connecting timing and logic controller 10 to the reel spinning mechanism and to the credit sensor of an existing slot machine. Timing and logic controller 10 may also be connected to a winning combination sensor in the existing slot machine. Thus, the continuous play retrofit kit disclosed herein may be quickly and inexpensively installed on an existing slot machine.
[0029] In the preferred embodiment, spin reels switch 6 and continuous play switch 8 were commercially available momentary contact switches. All slot machine components, including the credit sensor and the winning combination sensor are existing slot machine components, and readily available commercially. Timing and logic controller 10 may be a computer chip, electronic, electro-mechanical, mechanical, or other appropriate mechanism and/or circuit or digital processing unit. The connections between timing and logic controller 10 and continuous play switch 8, reels 4 and the credit and winning combination sensors may be electrical, mechanical, or some combination thereof, depending on the principal of operation of timing and logic controller 10.
[0030] While a preferred embodiment of the invention has been illustrated herein, it is to be understood that changes and variations may be made by those skilled in the art without departing from the spirit of the appending claims.
