[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.

The tip of the coin guide (that is, the portion connected to the payout opening) in the conventional coin payout device has a structure for ejecting one coin at a time (for example, US Pat.
4,518,011).

[Problems to be solved by the invention]

However, in the above conventional payout opening structure, after the final payout of the payout coin is completed, the cheat of the coin remaining in the coin guide (for example, an act of illegally scraping with a hook pin or the like) and mischief Defensive measures are inadequate. 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 can count accurately and reliably with a simple structure.

An object of the present invention is to provide a coin payout device for a game machine, which can prevent the cheat of coins with a simple structure.

[Means for solving problems]

In order to solve the above problems and achieve the object of the present invention,
The present invention is a coin payout device for a game machine, which is provided with a coin guide for guiding coins sequentially sent from the hopper side to a coin payout opening. The coin payout device is provided substantially parallel to the flip-out direction of the coins, and both ends are opposite to each other. In the radial direction of the coin, the rotating arm pivotally attached to the tip of the coin guide in the middle so as to rotate toward and away from the outer peripheral surface of the coin and the end of the rotating arm on the tip side of the coin guide. An urging means for urging toward the outer peripheral surface of the coin, a kick roller pivotally attached to the outer peripheral surface of the most advanced coin at the end of the rotating arm on the tip end side of the coin guide, and a rotating member. The other end of the moving arm is pivotally attached to the outer peripheral surface of another coin so that the kick roller comes into contact with the outer peripheral surface of the leading edge side of the leading edge coin in the feed direction. Abut on minute side outer peripheral surface A locking roller provided in that position, and comprising the.

[Action]

The present invention having the above structure 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 leading edge of the coin that reaches the tip of the coin guide is moved forward in front of the tip of the coin guide by the urging force applied to the tip of the rotating arm in the direction to pinch the outer circumference of the coin and the kick roller rolling on the outer circumference of the coin. It is played one by one. Each time each coin is flipped, the tip of the rotating arm approaches the outer peripheral surface of the coin,
Repeat the withdrawal exercise. Since this pivot arm is pivotally attached at the intermediate portion, the other end repeats rocking in the direction opposite to the tip.

At the other end of such a rotating arm, when the kick roller comes into contact with the outer peripheral surface of the front half of the coin in the forward direction, when the kick roller comes into contact with the outer peripheral surface of the other front half of the coin in the feeding direction A roller is provided so as to be capable of rolling contact with the outer peripheral surface of the coin. Therefore, if you try to scrape out the most advanced coin by some means after paying out a predetermined number of coins (cheat), the most advanced coin comes into contact with the kick roller, and the tip of the rotating arm moves the most advanced coin. Attempt to rotate in the opening direction to pass it. However, since the other end of the rotating arm rotates in the opposite direction, the lock roller provided there comes into contact with another coin, and the kick roller cannot rotate any further. At this time, by setting the positions of the kick roller and the lock roller in the predetermined positional relationship of the present invention, it becomes impossible to extract the most advanced coin, and it is possible to prevent the cheat of the coin. In this case, the mechanism is composed entirely of mechanical elements, and the fact that no electrical means is interposed also makes it possible to provide a simple structure.

〔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 of 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 and 4 via a spacer 5. Guide plate
The spacers 3 and 4 are attached by a spacer 5 with a gap 6 corresponding to the thickness of the coin 2. This gap 6 is the coin guide 1
A guide path for the coin 2 from the coin hopper is formed continuously in the extending direction of the. A rotating arm 7 is axially attached to the tip of the coin guide 1 in parallel with the feeding direction of the coin 2 (the direction in which the coin is ejected (arrow)).

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 projectingly and axially attached to an end portion (hereinafter, referred to as a tip end portion) of the coin guide 1 in the rotating arm 7 so as to face the tip opening of the coin guide 1. The kick roller 9
The peripheral surface of the coin (hereinafter referred to as the first coin) 2a located at the tip of the coin guide 1 is provided at a position where it can be brought into rolling contact with the outer peripheral surface.

The tip of the rotating arm 7 is a spring (biasing means).
It is always urged by 10 toward the outer peripheral surface side of the first coin 2a. When the lower half side outer peripheral surface of the first coin 2a is interposed between the peripheral surface of the kick roller 9 and the peripheral surface of the ejection assisting roller 17 provided at the tip of the coin guide 1 by the biasing force of the spring 10, The first coin 2a works so as to pinch it out. Therefore, the first coin 2a is the first
As shown in the figure, it is ejected vigorously in the direction of the arrow.

At the rear end of the rotating arm 7, a lock roller 12 inserted through a long hole 11 penetrating the coin guide 1 at a corresponding position is pivotally mounted. The lock roller 12 is provided at a position where the peripheral surface thereof can be brought into rolling contact with the outer peripheral surfaces of the second to third coins 2b and 2c following the first coin 2a.

In addition, a projecting piece 13 is provided at one end in the width direction of the rear end of the rotating arm 7.
Is provided, and a sensor 14 for detecting the rotation of the rotating arm 7 is provided at a position where the projecting piece 13 enters and leaves when the rotating arm 7 rotates in the direction of the arrow. Has been. This sensor 14 turns on every time the protrusion 13 comes in and out
It is a detector that outputs an OFF signal (pulse signal). The sensor 14 is preferably a non-contact type sensor, for example, a magnetic proximity switch, a photocoupler or the like is used. Since this detection signal is output each time the rotating arm 7 is rotated (that is, a coin flipping operation), it eventually corresponds to the number of coins to be paid out. Therefore, this detection signal is given to a counter (not shown), and the number of coins is calculated.

A stopper locking piece 15 is provided on the other end of the rotating arm 7 so as to project, and contacts the stopper 16 fixed to the coin guide 1 to restrict the rotation of the rotating arm 7.

Next, a series of operations will be described with reference to FIG. First, as shown in FIG. 2 (a), the coins 2a, 2b, 2c are sequentially sent from the hopper in a back-pressed state. At this time, the tip of the rotating arm 7 is pulled toward the first coin 2a by the spring 10.

Next, as shown in FIG. 2B, when each coin further advances and the first coin 2a interrupts between the auxiliary roller 17 and the kick roller 9, the tip end side of the rotating arm 7 Is opened against the biasing force of the spring 10, and the lock roller 12 moves to the coin side by that amount. Kick roller 9 at this time
Comes into contact with the maximum diameter portion of the first coin 2a, and the lock roller 12
Is located between the second coin 2b and the third coin 2c. On the other hand, at this time, the projecting piece 13 enters the sensor 14, a pulse signal is output from the sensor 14, and it is considered that one coin has been paid out, and is counted up by a counter (not shown).

Next, as shown in FIG. 2 (c), when the coin advances, the kick roller 9 is positioned and abuts on the outer peripheral surface of the lower half side of the first coin 2a. Then, the tip of the rotating arm 7 is pulled back by the accumulated biasing force of the spring 10,
The first coin 2a is held by the auxiliary roller 17 and the kick roller 9 and is vigorously ejected.

Next, as shown in FIG. 2 (d), after the first coin 2a has been flipped, the second coin 2b, which was the second largest until then, comes out first. At this time, the rotating arm 7 stands by at a position determined by the stopper 16. Thereafter, by repeating the same operation as above, each coin is flipped out one by one to pay out.

Next, the cheat prevention operation will be described. Consider a state where the number of payouts to be paid out is completed and the next payout is waited for.
As shown in FIG. 3, when the first coin 2a at the beginning is scraped by some means (for example, a hook pin) in the standby state, the outer peripheral surface of the first coin 2a on the front half side is kicked. Although it contacts the roller 9 and tries to open the tip of the rotating arm 7 as shown by the arrow, the rear end of the rotating arm 7 moves the lock roller 12 to the outer periphery of the front half of the second coin 2b due to the reaction force. Rotate to abut the surface. As a result, the lock roller 12 interferes with the feeding of the second coin 2b as the first coin 2a is pulled out, and eventually the first coin 2a is also prevented from being fed out by the kick roller 9 and cannot be taken out. It will be impossible. In this way, cheats can be prevented by determining the diameter of the coin and the size of the rotating arm 7.

According to this embodiment, in addition to the above cheat prevention, the movement of the rotating arm 7 is detected by the projecting piece 13 and the sensor 14, so that the rotating arm 7 can be operated without separately configuring a payout number detector. Can be diverted, and the device configuration can be simplified and miscount can be prevented.

[Effect of device]

As described above, according to the present invention, it is possible to prevent the coin from being illegally taken out (cheat) from the coin payout opening due to the interaction between the kick roller and the lock roller attached to the rotating arm. According to the configuration of the present invention, since it is configured only by a mechanical mechanism without using electrical means, it has a simple configuration and can reliably prevent cheats even during a power failure or the like.
