DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a slot machine which inserts medals and coins for use, a vending machine and the like (hereinafter referred to as a slot machine, etc.) for properly forcibly discharging abnormal medals. Medal discharge mechanism of a slot machine or the like for use.

[0002]

2. Description of the Related Art Slot machines and the like that insert and use medals and coins (hereinafter simply referred to as medals) are widely used.

[0003] In these slot machines and the like, an abnormal medal discharging mechanism is incorporated for discriminating between normal medals and abnormal medals and forcibly discharging abnormal medals to the outside.

As an example of a conventional abnormal medal discharge mechanism,
It is known that the clapper S1 of the solenoid S is extended long toward the base plate B, and the tip thereof is inserted into a square hole B1 formed in the base plate B so as to be able to move back and forth (FIG. 6).

In this apparatus, the clapper S1 is formed in an L-shape, and when the solenoid S is not energized, the clapper S1 is retracted by the spring S2 (solid line in the figure), and the tip of the clapper S1 is On the front side of the plate B1, a part of a sloping path K for dropping the medal M is formed. On the other hand, when the solenoid S is energized, the clapper S1 moves forward (two-dot chain line in the figure), and the medal M is Can be dropped downward and discharged outside through a discharge hole S1a formed in the clapper S1. The oblique path K is formed by disposing a guide plate G on the front side of the base plate B via a spacer G1, and the solenoid S has a medal M which is an abnormal medal by a medal discriminating circuit (not shown). It is assumed that power is supplied when it is determined that

[0006]

However, according to the prior art, there is a problem that the operation of discharging abnormal medals may be uncertain. That is, the clapper S1 is L
It is formed in a shape and forms a part of the sloping path K on which the medal M falls, so that when the solenoid S is energized to move the clapper S1 forward, the tip of the clapper S1 moves its pivot point S1b. It will make a circular motion around the center. Therefore, the square hole B1 provided in the base plate B needs to be enlarged vertically, and the clapper S1 inevitably forms a large gap d with the upper end edge of the square hole B1 during its forward movement. . Therefore, the medal M may not fall correctly from the discharge hole S1a, may be obliquely bitten into the gap d, and the subsequent operation may be disabled.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, an object of the present invention is to dispose an abnormal medal by providing a clapper and a discharge plate separately and moving the discharge plate back and forth at right angles to the base plate. An object of the present invention is to provide an abnormal medal discharge mechanism for a slot machine or the like that can reliably perform an operation.

[0008]

In order to achieve the above object, a configuration of the present invention penetrates a base plate so as to be able to move back and forth, and forms a part of an oblique path on the front side of the base plate for falling medals. A discharge plate having a discharge hole for dropping abnormal medals, and a solenoid for driving the discharge plate are provided.The discharge plate and the clapper of the solenoid are connected so that the relative angle can be changed, and the discharge plate is connected to the base plate. On the other hand, moving back and forth at right angles is the gist.

The discharge plate may be positioned so as to be substantially immovable up and down with respect to the base plate.

[0010]

With this configuration, when the discharge plate is advanced in the direction of the base plate by the solenoid, the abnormal medal can be discharged through the discharge hole.
The discharge plate is connected to the solenoid clapper so that the relative angle can be changed, and moves back and forth at right angles to the base plate, so even when moving forward, harmful gaps are formed on the upper surface of the discharge plate There is no danger at all.

When the discharge plate is positioned so as to be substantially immovable up and down, the discharge plate does not move vertically in a plane parallel to the base plate.
There is no danger that the form of the sloping path on which the medals fall will not change, and therefore, the tumbling operation of the medals can be further stabilized.

[0012]

Embodiments will be described below with reference to the drawings.

An abnormal medal discharging mechanism of a slot machine or the like includes a solenoid 10 and a discharging plate 21 (FIG. 1).

The solenoid 10 is a clapper type solenoid and is mounted on a base plate 22 via a bracket 10a.

A straight path K1 for inserting a medal M is formed in the upper part of the base plate 22 by mounting a pair of guide members 23, 23 facing each other (FIGS. 1 and 2). The guide plate 2 is provided at the center of the base plate 22.
By arranging 4 and 25 diagonally, a sloping path K that is continuous with the straight path K1 is formed (FIGS. 1 and 3). However, the upper guide plate 25 is attached to the base plate 22 by a distance equivalent to the thickness of the medal M via a spacer 25a, and one end of the guide plate 25 on the straight path K1 side is bent upward. It covers both the straight path K1 and the sloping path K.

The discharge plate 21 is disposed on the downstream side of the lower guide plate 24 so as to form a part of the oblique path K together with the guide plate 24. The discharge plate 21 has a discharge hole 21a on the upper surface, leg portions 21b, 21b formed on both sides, and a rear end portion is connected to a front end portion of the clapper 11 of the solenoid 10 via bolts 13, 13. (FIGS. 1 and 4).

The solenoid 10 includes a coil 12, a clapper 11, and a tension spring 11a for urging the clapper 11. The clapper 11 is connected to a frame 12a of the solenoid 10 via hinges 11b, 11b. Bolts 13 and 13 are respectively provided with washers 1.
3a, a weak compression spring 13b is mounted. The tip of the discharge plate 21 is provided with a square hole 22a provided in the base plate 22.
Through the base plate 22 (FIGS. 4 and 5),
The height of the legs 21b, 21b of the discharge plate 21 is the square hole 22a.
Is set to be slightly smaller than the maximum height h.

The base plate 22 has a discharge gutter 22b formed downstream of the oblique path K (FIG. 1).

When the coil 12 of the solenoid 10 is not energized, the clapper 11 is urged backward by the tension spring 11a, so that the discharge plate 21 is also at the retracted position (solid line in FIG. 4). At this time, the discharge plate 21 is positioned such that the front end is inserted into the square hole 22a of the base plate 21 and the rear end is connected to the clapper 11 and positioned. And they are almost perpendicular.

Now, when a medal M is inserted from above the straight path K1, the medal M falls on the straight path K1 and enters the oblique path K, and the upper end face of the lower guide plate 24 and the upper face of the discharge plate 21 are removed. It falls down being guided by the upper guide plate 25, and can be taken into the machine via the discharge gutter 22b. However, at this time, on the upper surface of the discharge plate 21, the medal M passes on the shelf 21c existing between the discharge hole 21a and the front surface of the base plate 22. Therefore, a sensor (not shown) is provided in the course of the medal M, particularly in the middle of the straight path K1, and it is necessary to determine whether the inserted medal M is normal or abnormal based on an output signal of the sensor. And a medal determination circuit (not shown).

When the inserted medal M is an abnormal medal, the medal discriminating circuit detects the coil 12 of the solenoid 10
Turn on electricity. As a result, the clapper 11
(The two-dot chain line in FIG. 4) and the discharge plate 21 advances toward the base plate 22, so that the shelf 21c on the discharge plate 21
Disappears from the front surface of the base plate 22, so that the medal M can be dropped downward through the discharge hole 21a. The abnormal medals that have fallen downward in this manner are forcibly discharged out of the machine via a discharge path (not shown) without being taken into the machine.

Here, the discharge plate 21 is connected to the clapper 11 so that the relative angle can be freely changed. Bolt 1
The weak compression springs 13b, 13b are attached to 3, 13, and the connection between the discharge plate 21 and the clapper 11 can be opened and closed at an arbitrary angle by the expansion and contraction of the compression springs 13b, 13b. Because. Therefore,
When the clapper 11 is sucked, the discharge plate 21
Can move forward while maintaining a substantially initial right-angled state with respect to the base plate 22 even if the tip makes a circular motion around the hinges 11b.

When the ejection of the abnormal medals is completed, the energization of the solenoid 10 is stopped, and the ejection plate 21 is returned to the original retracted position to prepare for the next insertion of the medals M.

In the above description, by setting the height of the legs 21b, 21b to be slightly smaller than the maximum height h of the square hole 22a, the discharge plate 21 is positioned substantially immovably up and down. (FIG. 5). Also, by setting the width of the discharge plate 21 to be slightly smaller than the width D of the square hole 22a, the discharge plate 21 is substantially immovable in any direction in a plane parallel to the base plate 22. Can be.

[0025]

As described above, according to the present invention, the discharge plate and the solenoid are provided, and the discharge plate and the clapper of the solenoid are connected so that the relative angle can be changed. On the other hand, it is possible to move forward while maintaining the original right angle state and discharge abnormal medals,
At this time, since there is no room for a harmful gap on the upper surface of the discharge plate, there is no possibility that a malfunction occurs due to the medal being caught in the gap, and the abnormal medal can be reliably discharged. Has an excellent effect.
