Abstract

(57) [Summary] [Purpose] When the beating is over, the stop position of the cam that hits the hammer is kept constant so that there is no deviation in the launch timing when restarting next. [Structure] A cam 13 for flipping a hammer 15 is integrally attached to one end of a motor shaft of a stepping motor 10,
A light shielding plate 20 having a slit in the radial direction on the other end side is integrally attached to the hammer 13 while maintaining a constant angular relationship. A photo interrupter 21 for detecting the slit of the light shielding plate 20 is arranged at the outer peripheral position of the light shielding plate 20. Further, between the stepping motor 10 and the handle 25, a start signal is received to output a motor-on signal to drive the stepping motor 10, and after a stop signal is received, a slit detection signal is input from the photo interrupter 21. An electric control means 11 for emitting a motor off signal for stopping the driving of 10 is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a ball launching device of a pachinko game machine in which a hammer is used to hit a ball with a cam.

[0002]

[Prior art]

 Conventionally, in this type of ball launching device, as shown in FIG. 5, for example, a cam 2 is integrally attached to a motor shaft 1 of a stepping motor (not shown), and a hammer 3 is arranged in proximity to the cam 2 and The hammer 3 is rotatably supported by a support shaft 4 and is elastically urged in one direction by an elastic member 5. Then, when starting to hit a ball, as shown in FIG. 6, for example, a stepping motor is driven by a handle operation to rotate a cam 2 and a hammer 3 is hit by the cam 2 to hit a ball 6. On the other hand, when finished, the drive of the stepping motor was stopped by operating the handle.

[0003]

[Problems to be solved by the device]

 However, the conventional ball launching device has a problem that the stop rotation position of the cam 3 is not constant when the ball striking is finished and the stepping motor is stopped, which causes variation. Therefore, when the ball is restarted next time, the time interval between the operation and the hammer 2 being played by the cam 2 is not constant, and the timing at which the ball 6 is hit is deviated, so that the player can enjoy the game as he or she desires. I couldn't.

Therefore, an object of the present invention is to make the stop rotation position of the cam for hitting the hammer always constant when finishing the ball striking of the pachinko gaming machine, and to eliminate the deviation of the launch timing at the time of restarting next. is there.

[0005]

[Means for Solving the Problems]

 Therefore, in the present invention, as shown in the following illustrated embodiment, for example, a stepping motor 10 rotates a cam 13, and the cam 13 hits a hammer 15 urging the elastic member 32 in one direction to hit a ball 30. In the ball launching device of the pachinko gaming machine, the cam rotation position detecting means 35 for detecting that the cam 13 has reached the predetermined rotation angle position, and the cam rotation position detecting means 35 after receiving the stop signal. When an output signal is input, the electronic control means 11 is provided for issuing a motor off signal for stopping the driving of the stepping motor 10.

[0006]

[Action]

 In this invention, when the ball 30 is hit, for example, when a start signal is sent to the electric control means 11 by operating the handle, the stepping motor 10 is driven to rotate the cam 13, and the hammer 13 is flipped by the cam 13 to hit the ball. Strike 30. On the other hand, when the ball striking is finished, for example, a stop signal is sent to the electric control means 11 by a steering wheel operation, and when an output signal is input from the cam rotation position detection means 35, the electric control means 11 issues a motor off signal to output the stepping motor 10. Stop the drive.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 4 shows a partial configuration of a ball launching device of a pachinko gaming machine which is an embodiment of the present invention.

Reference numeral 10 in the figure is a stepping motor of the ball launching device. The stepping motor 10 is appropriately supported and provided in a pachinko machine body (not shown).

A cam 13 is integrally attached to the motor shaft 12 of the stepping motor 10 at one end 12a side. The cam 13 is plate-shaped and has a protrusion 13a on the outer periphery as shown in FIG.

A hammer 15 is rotatably provided at a position near the cam 13 while being supported by a support shaft 16. The hammer 15 is an inverted V-shaped lever that rotates around the support shaft 16, and has a roller 17 rotatably attached to the tip of one end 15a by a shaft 18 and an end of the other end 15b outwardly. Bend at a right angle and attach the coil spring 19 to the tip. One end of the elastic member 32 is hooked on the other 15b of the hammer 15. The elastic member 32 has the other end hooked at an appropriate position to urge the hammer 15 clockwise in the drawing.

Further, as shown in FIG. 4, on the other end 12b side of the motor shaft 12 of the stepping motor 10, as shown in FIG. 2, a light shielding plate 20 having a circular shape and a slit 20a in its radial direction is formed. Are attached integrally. At that time, the light shielding plate 20 makes the angular relationship between the slit 20a and the cam 13 constant. A photo interrupter 21 is fixed to the stepping motor 10 at an outer peripheral position of the light shielding plate 20. Then, the photo interrupter 21 and the light shielding plate 20 form a cam rotational position detecting means 35.

Reference numeral 22 in FIG. 4 is a connection terminal electrically connected to the stepping motor 10 with a code 23. Then, as shown in FIG. 1, the stepping motor 10 is electrically connected to an electric control means 11 for inputting a motor on / off signal, and the electric control means 11 inputs a start on / off signal. It is electrically connected to the steering wheel 25.

Then, when the ball is shot using this ball launching device, the handle 25 of the pachinko gaming machine is rotated. Then, the switch is turned on in conjunction with the turning operation of the handle 25, and a start signal is sent to the electric control means 11. Then, the electric control means 11 sends a motor-on signal to drive the stepping motor 10, rotate the cam 13, and hit the hammer 15. That is, in detail, when the cam 13 rotates in the direction of arrow A in FIG. Turn to. When the cam 13 further rotates, the engagement between the cam 13 and the roller 17 suddenly disengages, and the elastic member 32 causes the hammer 15 to return to the clockwise direction. Strike the ball 30.

On the other hand, when the beating is finished, the handle 25 shown in FIG. 1 is returned to the original position. Then, the switch is turned off in synchronization with the returning operation, and a stop signal is sent to the electric control means 11. After that, the slit 20 a of the light shielding plate 20 is detected by the photo interrupter 21, and the slit detection signal is sent to the electric control means 11. Then, when the electric control means 11 receives the stop signal and then receives the slit detection signal, it sends a motor off signal to stop the driving of the stepping motor 10.

In the above-described embodiment, when the beating is finished, the handle 25 is returned to turn off the switch, and the stop signal is sent to the electric control means 11. However, it can also be applied to a device which turns off the switch by means other than the handle 25 and sends a stop signal to the electric control means 11.

[0016]

[Effect of device]

 Therefore, according to the present invention, when the ball striking is finished, a stop signal is sent to the electric control means, and then when the output signal is input from the cam rotation position detection means, the electric control means issues a motor off signal to output the stepping motor. Since the drive is stopped, the cam stop position can be kept constant and the misalignment of the launch timing when restarting the ball launch can be eliminated, allowing the player to enjoy the game at his own timing. it can.
