And then the control device 101 outputs a prescribed sound output signal for supplying to the sound output device 107 at the time of acquire success and outputs a prescribed emission signal to the LED group 108 when it receives the acquisition success signal.

[0075] The sound output device 107 outputs a sound meeting the prescribed sound output signal when it receives the prescribed sound signal from the control device 101, and the LED group 108 also emits light with a emission pattern meeting the prescribed sound output signal when it receives the prescribed emission signal from the control device 101.

[0076] And, when the motor driver 104 receives a drive control signal from the control device 101, it controls the driving of the motor by sending the power corresponding to the signal to the X axis motor 109, Y axis motor 110 and Z axis motor 111. The X axis motor 109 moves the crane main body 54 in X axis direction corresponding to the control of the motor driver 104, the Y axis motor 110 moves the crane main body 54 in Y axis direction corresponding to the control of the motor driver 104 and the Z axis motor 111 also moves the crane main body 54 in Z axis direction corresponding to the control of the motor driver 104.

[0077] The X axis first switch 112 outputs a X axial motor stop signal to the control device 101 when it is pushed by the crane main body 54 in case that the crane main body 54 returns to the original position, the X axis second switch 113 outputs the X axial motor stop signal to the control device 101 by being pushed by the crane main body 54 in case that the crane main body 54 is moving to the X axis direction by the X axis motor movable signal output from the first button 24, and the control device 101 cuts off the X axis motor movable signal from the first button 24 and turns the second button 25 to a standby state.

[0078] Also, the Y axis first switch 114 outputs a Y axial motor stop signal to the control device 101 when it is pushed by the crane main body 54 in case that the crane main body 54 returns to the original position, and the Y axis second switch 115 outputs the Y axial motor stop signal to the control device 101 by being pushed by the crane main body 54 in case that the crane main body 54 is moving to the Y axis direction by the Y axis motor movable signal output from the second button 25.

[0079] Then, the action of the crane game machine 1 of the embodiment is described below. When batteries are housed and the main switch 102 is turned ON, as shown in FIG. 6, the control device 101 determines whether the crane main body 54 is in an initial position by using signals from the X axis first switch 112 or Y axis first switch 114 (STEP S1), and moves the crane main body 54 to the initial position if it is not in the initial position (STEP S2). If it is confirmed that the crane main body 54 is in the initial position in the STEP S1, the insertion charging of a coin is operated (STEP S3), and the sound begins to be output and the LED group 108 begins to be emitted if the coin is inserted (STEP S4). In this time, the voice of characters and the like is supplied firstly and then the BGM (Back Ground Music) and the like are supplied. When the output of the voice of characters is completed in this sound output step, the first button 24 can be operatable.

[0080] And then, the control device 101 determines whether a button operatable prescribed time passes after inserting the coin (STEP S5), the control device 101 returns to the standby state of before inserting the coin if the prescribed time has passed. If the prescribed time has not passed, the control device 101 determines the X axial motor movable signal generated by pressing the first button 24 (STEP S6), and the crane main body 54 starts to move in the X axis direction if the X axial motor movable signal is output (STEP S7).

[0081] Continuously, the control device 101 determines whether the X axial motor movable signal is continuously output (STEP S8), the movement of the crane main body 54 in X axis direction is stopped if the X axial motor movable signal is not output (STEP S10). If the X axial motor movable signal is continued, the control device 101 determines the X axial motor stop signal which is output in case that the crane main body 54 moves to the limit position so as to press the X axis second switch 113 (STEP S9), the movement in X axis direction is stopped if the X axial motor stop signal is output (STEP S10). The control device 101 continues to move the crane main body 54 in X axis direction if the X axial motor stop signal does not output in the STEP S9 detecting the X axial motor stop signal. And, when the axial motor movable signal does not continue or the movement in X axis direction is stopped by inputting the X axial motor stop signal, the first button 24 can not be operated (STEP S11).

[0082] The control device 101 confirms again whether the prescribed time has passed after inserting the coin after the first button 24 was operated (STEP S12), the crane main body 54 is returned to the initial position so as to be finished if the prescribed time has passed (STEP S2). And, when the prescribed time has not passed, as shown in FIG. 7, the control device 101 determines the Y axial motor movable signal generated by pressing the second button 25 within a prescribed time frame (STEP S13). And then, the crane main body 54 starts to move in Y axis direction if the Y axial motor movable signal is output (STEP S14).

[0083] And, the control device 101 determines whether Y axial motor movable signal is continuously output (STEP S15), the movement of the crane main body 54 in Y axis direction is stopped if the Y axial motor movable signal is not output (STEP S17). If the Y axial motor movable signal is output, the control device 101 determines the Y axial motor stop signal which is output in case that the crane main body 54 moves to the limit position so as to press the Y axis second switch 115 (STEP S16), the movement in Y axis direction is stopped if the Y axial motor stop signal is output (STEP S17). Where, the crane main body 54 continues to move in Y axis direction if the Y axial motor stop signal is not output in STEP S16.

[0084] When the movement of the crane main body 54 in Y axis direction is stopped, the Z axis motor 111 for moving the catcher 65 starts to rotate forwardly and the catcher 65 is moved down with opening (STEP S18). And, after the catcher 65 is moved down to the bottom end with the passage of prescribed time, the Z axis motor 111 starts to rotate reversely and the catcher 65 is moved up with closing (STEP S19). And, when the catcher 65 is moved up to the upper end by the time same as falling time, the crane main body 54 is returned to the initial position (STEP S20).

[0085] The catcher 65 starts to move downwardly by forwardly rotating the Z axis motor 111 of the crane main body 54 returned to the initial position by the control device 101 (STEP S21), and the success and failure of the acquisition of prize 6 is detected by the infrared sensor 106 (STEP S22). At this point, when the control device 101 receives the acquisition success signal from the infrared sensor 106 in case that the prize 6 was successfully caught, the sound which praise the success of acquisition is output and the LED group 108 are emitted (STEP S23), and then the catcher 65 is returned to the initial position with reversely rotating the Z axis motor 111 (STEP S24) and all operations are finished. On the other, since the infrared sensor 106 does not react if the prize 6 was not caught, the control device 101 moves the catcher 65 downwardly with continuing the forwardly rotating of the Z axis motor 111 (STEP S25), and then it moves the catcher 65 upwardly with reversely rotating the Z axis motor 111 (STEP S26) and all operations are finished.

[0086] In accordance with the crane game machine 1 of the present embodiment, the crane main body 54 is controlled by the first button 24 for controlling the movement in X axis direction and the second button 25 for controlling the movement in Y axis direction, and the first button 24 does not react even it is pressed again after releasing, thus, one play can be by one coin. Therefore, the crane game machine 1 close to a real machine can be provided, and a player can be enjoyed with a sensation of strain during the play by paying attention the timing of releasing the first button 24 or second button 25.

[0087] Also, the front edge of the catcher 65 is formed like a hook so as to be horizontal state in case of closing, and wall surfaces are formed using the part of the holding member 73 in the side surfaces facing each other and standing wall plates 76 are mounted at the opening sides, thus, the crane game machine 1 which young children can catch the prize 6 with a high success rate can be provided. Moreover, the more popular crane game machine 1 among young children can be provided by adjusting the picture of characters or sounds to the machine. And, since the prize receiving tray 35 is protruded from the base part 2, young children can easily take out the prize 6 which is successfully caught.
