Description

The present invention relates to a coin payout device provided in a game machine such as a slot machine, and more particularly to a coin payout structure at a tip of a coin guide.

[Conventional technology]

The coin payout device is a device for automatically paying out a large number of coins collected in a hopper one by one from a payout opening through a coin guide in a number corresponding to a game win rate.

In the conventional coin payout device, the payout opening at the tip of the coin guide has a structure in which one coin is vigorously ejected (for example, US Pat. No. 4,518,001).

[Problems to be solved by the invention]

However, in the above conventional payout structure, the cheat of the coin remaining in the coin guide (or in the next payout holding state) after the final payout of the payout coin is finished (for example, using a hook pin or the like, is illegal). Acts such as scratching) and defensive measures against mischief are insufficient. On the other hand, since it is necessary to accurately count the number of coins paid out, there is a demand for a counting device that has a simple structure and that can count accurately and reliably.

Therefore, an object of the present invention is to provide a coin payout device for a game machine, which can count the number of coins accurately and surely with a simple structure and prevent the occurrence of miscount.

[Means for solving problems]

In order to solve the above conventional problems, the present invention provides a coin payout device for a game machine, comprising a coin guide (1) for guiding coins (2) sequentially sent from a hopper side to a coin payout opening. A rotary arm (7) having an end located on the front end side of the guide (1) rotatably mounted in the radial direction of the coin (2), and the rotary arm (7). The kick roller (9) pivotally attached to the outer peripheral surface of the most advanced coin (2) at the end and the end of the rotating arm (7) are arranged in the radial direction of the coin (2). Along with the biasing means (10) for biasing the kick roller so that the kick roller is pressed against the outer peripheral surface of the coin (2), and the star-shaped projections (12) protruding radially on the outer peripheral surface, a substantially star shape is formed. And the outer peripheral surface of the kick roller (3) is attached to the outer peripheral surface of the coin (2). ), A substantially star-shaped count cam (11) mounted rotatably in the circumferential direction at the tip of the coin guide (1) at a position where the coin (2) is sandwiched in the radial direction, and the count. A sensor (13) that outputs a pulse signal each time the star-shaped projection (12) of the cam (11) rotates, and a preset counter that produces an output when the output of the sensor (13) is counted and reaches a preset value. (14) and an alarm means (18) for outputting an alarm by the output of the preset counter (14).

[Operation] The present invention configured as described above operates as follows. Each coin is sequentially sent from the hopper side to the coin payout opening one by one while being pushed backward. The most advanced coin that reaches the tip of the coin guide is sandwiched between the kick roller and the concave portion between the adjacent star-shaped projections on the outer peripheral surface of the star-shaped count cam. At this time, when the coin is pushed backward, the contact position between the kick roller and the outer peripheral surface of the coin comes to the rear of the maximum diameter of the coin, and the kick roller is biased to the side that presses the coin, so the coin is picked up. It is played like this. At this time, the coin hits the star-shaped projection of the count cam to rotate the count cam. This rotation is detected by a sensor that detects the movement of the protrusion of the count cam in a non-contact manner, and a pulse signal is output for each rotation.

This pulse signal is given to the preset counter. When the number of pulses reaches the preset value set in the preset counter, the preset counter produces an output.
The alarm means is driven by the output of the preset counter and an alarm is issued.

In this way, the state in which the coins are actually flipped out is directly detected by the counting cam, so that the number of coins to be paid out can be accurately and reliably counted.

When the number of coins paid out reaches a value corresponding to the preset value, if you try to withdraw more coins, an alarm will be issued by the alarm means, preventing the withdrawal of coins by force. can do.

〔Example〕

 Next, an embodiment according to the present invention will be described with reference to the drawings.

FIG. 1 shows the structure of the tip of the coin guide in the coin payout device of the present invention.

The coin guide 1 is a member for guiding the coins 2 sequentially sent out from a coin hopper (not shown) to a coin payout opening (not shown). The coin guide 1 is formed by laminating two guide plates, 3, 4 with a spacer 5 interposed therebetween. The guide plates 3 and 4 are attached by a spacer 5 with a gap 6 corresponding to the thickness of the coin 2. The gap 6 is continuous in the extending direction of the coin guide 1 and forms a guide path for the coin 2 from the coin hopper. The coin 2 is fed at the tip of the coin guide 1 (the direction in which the coin is ejected (arrow)).
A rotating arm 7 is axially mounted in parallel with.

The rotating arm 7 is pivotally mounted on a shaft 8 and is rotatable along the radial direction of the coin 2. A kick roller 9 is axially attached to an end portion (hereinafter, referred to as a tip portion) of the coin guide 1 of the rotating arm 7 so as to face a tip opening of the coin guide in a protruding state. Kick roller 9
The outer peripheral surface of the coin is profitable at a position where the outer peripheral surface of the coin (hereinafter referred to as the first coin) 2a located at the tip of the coin guide 1 can be rolled and contacted. In addition, the tip of the rotating arm 7 is constantly moved by the spring (biasing means) 10 to the first coin 2
It is biased toward the outer peripheral surface side of a.

On the other hand, a substantially star-shaped count cam 11 is mounted on the side facing the kick roller 9. Count cam 11
Is the star-shaped protrusion 12 and another star-shaped protrusion 12 adjacent thereto.
The concave surface formed by is contacted with the outer peripheral surface of the first coin 2a.

A counting sensor 13 is provided on the side of the counting cam 11. The counting sensor 13 has a U-shaped outer shape, and each star-shaped protrusion 12 of the count cam 11 is provided in the void.
Are formed so that they can pass through. A non-contact type sensor such as a photocoupler or a magnetic proximity switch is provided in the void, and one pulse signal is output each time the star-shaped projection 12 passes through the void of the sensor 13.

Next, as shown in FIG. 2, the output pulse signal of the counting sensor 13 is given to the preset counter 14.
A preset count value corresponding to the number of coins paid out according to the winning rate of the game is set in the preset counter 14 and is counted when the pulse signal from the counting sensor 13 is input by the preset count value. It becomes over, outputs one pulse signal, and is reset. The preset count value is given from a microprocessor (hereinafter, referred to as CPU) 15 that controls the game machine in a centralized manner.

The output signal of the preset counter 14 is given to the driving device 16. The drive device 16 operates the lock means for locking the count cam 11 by the output signal of the preset counter 14. The electromagnetic solenoid 17 is used as this locking means. The slider 18 of the electromagnetic solenoid 17 is provided at a position where it abuts on the star-shaped projection 12 of the count cam 11 when it advances and blocks the rotation of the count cam 11.

On the other hand, the output signal of the preset counter 14 is the alarm device 1.
Given to 8. The alarm device 18 is a preset counter 1.
4 is output and the output of the counting sensor 13 is ANDed, and after the output signal of the preset counter 14 is input (end of coins to be paid out), further output of the counting sensor 13 is generated (counting This means that the cam 11 has moved and coins that should not be paid out have been put out.) In that case, it means that cheats have been made illegally.
It gives an alarm.

The electromagnetic solenoid 17 and the alarm device 18 may be alternatively used, or both may be provided together.

Next, a series of operations will be described. When paying out coins, the coins 2a, 2b ... Are sent from the hopper while being pushed. At this time, the tip of the rotating arm is pulled by the spring 10. Further, as each coin advances, the first coin 2a will interrupt between the count cam 11 and the kick roller 9, and the kick roller 9 will rotate in the direction of being gradually expanded. Eventually, the first coin 2
When the first coin 2a advances to such an extent that the kick roller 9 is located below the outermost diameter of a, the kick roller 9 acts by the biasing force of the spring 10 to eject the first coin 2a, and the first coin 2a Is played vigorously. At this time, the first coin 2a hits the star-shaped protrusion 12 of the count cam 11, and the count cam 11 rotates in the direction of the arrow. By this rotation, the star-shaped protrusion 12 passes through the counting sensor 13, and a pulse signal is output. This pulse signal is counted by the preset counter 14.

The same operation is repeated thereafter, and when the preset value given from the CPU 15 is reached is the completion of the number of payouts, the electromagnetic solenoid 17 operates and the count cam 11 is locked. As a result, coin payout thereafter is prohibited. If someone tries to cheat, the alarm device 18 will be activated and prevented.

[Effect of device]

As described above, according to the present invention, the coin payout is directly detected by the counting cam, so that the coin can be counted accurately and surely.

After the number of coins paid out reaches a value corresponding to the preset value, if you try to withdraw more coins, an alarm will be issued by the alarm means, preventing the withdrawal of coins by force. can do.
