Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is capable of accurately forcibly discharging abnormal medals in gaming machines such as slot machines, vending machines, etc. (hereinafter referred to as slot machines, etc.) in which medals and coins are inserted. This invention relates to an abnormal medal ejection mechanism for slot machines, etc.

0002

2. Description of the Related Art Slot machines and the like that are used by inserting medals or coins (hereinafter simply referred to as medals) have become widely used.

[0003] These slot machines and the like are equipped with an abnormal medal ejecting mechanism for distinguishing between normal medals and abnormal medals and forcibly ejecting the abnormal medals to the outside.

[0004] As an example of a conventional abnormal medal ejection mechanism,
The clapper S1 of the solenoid S is extended toward the base plate B, and its tip is inserted into the square hole B1 provided in the base plate B.
It is known that the device is inserted so that it can move back and forth (Fig. 6).

In this device, the clapper S1 is formed into an L shape, and when the solenoid S is not energized, the clapper S1 is moved back by the spring S2 (solid line in the same figure), and at this time, the tip of the clapper S1 is attached to the base. On the front side of the plate B1, a part of the diagonal path K for falling the medal M is formed, and when the solenoid S is energized, the clapper S
1 moves forward (double-dashed line in the figure), and the medal M can be dropped downward and discharged to the outside through the discharge hole S1a formed in the clapper S1. Note that the diagonal path K is
It is formed by arranging a guide plate G on the front side of the base plate B via a spacer G1, and the solenoid S is
It is assumed that electricity is supplied when a medal discrimination circuit (not shown) determines that the medal M is an abnormal medal.

[0006]

[Problems to be Solved by the Invention] This conventional technique has a problem in that the ejection operation of abnormal medals may become uncertain. That is, clapper S1 is
Since it is formed in an L shape and forms a part of the oblique path K on which the medal M falls, when the solenoid S is energized to move the clapper S1 forward, the tip of the clapper S1 moves toward its pivot point S1b. It will move in an arc centered on . Therefore, the square hole B1 provided in the base plate B needs to be enlarged vertically, and when the clapper S1 moves forward, there is a large gap d between the square hole B1 and the upper edge of the square hole B1.
is inevitable. Therefore, medal M
This is because there was a risk that the gas would not fall properly from the discharge hole S1a and would be obliquely caught in the gap d, making subsequent operation impossible.

In view of the problems of the prior art, an object of the present invention is to provide a clapper and a discharge plate separately, and to move the discharge plate back and forth at right angles to the base plate, thereby discharging abnormal medals. To provide an abnormal medal discharging mechanism for a slot machine, etc., which can operate reliably.

[0008]

[Means for Solving the Problems] The structure of the present invention for achieving the above object is to form a part of a diagonal path that passes through the base plate so as to be movable back and forth and allows the medals to fall on the front side of the base plate. It is equipped with a discharge plate having a discharge hole for dropping abnormal medals, and a solenoid that drives the discharge plate, and 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, its gist is to move back and forth at right angles.

[0009] The discharge plate may be positioned so as to be substantially immovable up and down with respect to the base plate.

0010

[Operation] With this configuration, when the ejection plate is moved forward in the direction of the base plate by the solenoid, the abnormal medal can be ejected through the ejection hole, but at this time,
The discharge plate is connected to the solenoid clapper so that its relative angle can be changed, and it moves back and forth at right angles to the base plate, so even when moving forward, a harmful gap is formed on the top surface of the discharge plate. There is no risk of it happening.

[0011] Furthermore, when the ejection plate is positioned so that it cannot substantially move up and down, the ejection plate remains vertically immovable in a plane parallel to the base plate.
There is no fear that the form of the oblique path on which the medals fall will change, and therefore the falling motion of the medals can be made more stable.

0012

[Embodiment] An embodiment will be explained below with reference to the drawings.

[0013] The abnormal medal discharging mechanism of a slot machine etc. is equipped with 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 pair of guide members 23, 23 are attached to the upper part of the base plate 22 so as to face each other, thereby forming a straight path K1 into which the medals M are inserted (FIGS. 1 and 2). Further, a guide plate 24 is provided at the center of the base plate 22.
, 25 are arranged diagonally, thereby forming an oblique path K that is continuous with the straight path K1 (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 oblique path K.

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

The solenoid 10 includes a coil 12, a clapper 11, and a tension spring 11a that biases the clapper 11. The clapper 11 is connected to a frame 12a of the solenoid 10 via hinges 11b, 11b. In addition, the bolts 13 and 13 each have a washer 13.
a. A weak compression spring 13b is attached. Note that the tip of the discharge plate 21 passes through the base plate 22 through a square hole 22a provided in the base plate 22 (FIGS. 4 and 5), and the height of the legs 21b and 21b of the discharge plate 21 is as follows. , is set slightly smaller than the maximum height h of the square hole 22a.

A discharge gutter 22b is formed in the base plate 22 on the downstream side of the oblique path K (FIG. 1).

When the coil 12 of the solenoid 10 is not energized, the clapper 11 is urged rearward by the tension spring 11a, and therefore the discharge plate 21 is also in the retracted position (solid line in FIG. 4). At this time, the distal end of the discharge plate 21 is inserted into the square hole 22a of the base plate 21 and positioned, and the rear end is connected to the clapper 11 and positioned, and the discharge plate 21 as a whole is positioned relative to the base plate 22. Assume that the angle is approximately right angle.

Now, from above the straight path K1, the medal M
When the medal M is thrown in, the medal M falls down the straight path K1, enters the oblique path K, and hits the upper end surface of the lower guide plate 24 and the discharge plate 2.
1 can be guided by the upper guide plate 25 and fall down, and taken into the machine via the discharge gutter 22b. However, at this time, it is assumed that the medals M pass over a shelf 21c existing between the discharge hole 21a and the front surface of the base plate 22 on the upper surface of the discharge plate 21. Therefore, in order to dispose a sensor (not shown) in the middle of the traveling path of the medal M, especially in the middle of the straight path K1, and to determine whether the inserted medal M is normal or abnormal based on the output signal of the sensor. , a medal discrimination circuit (not shown) is provided.

[0021] When the inserted medal M is an abnormal medal, the medal discrimination circuit activates the coil 12 of the solenoid 10.
energize. As a result, the clapper 11 moves the coil 12
(double-dashed 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, and therefore the medal M can be dropped downward through the discharge hole 21a. Furthermore, the abnormal medals that have fallen downward in this way are forcibly ejected 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 its relative angle can be changed. bolt 13
, 13 are attached with weak compression springs 13b, 13b, and as the compression springs 13b, 13b expand and contract,
This is because the connecting portion between the discharge plate 21 and the clapper 11 can be opened and closed at any angle. Therefore, even if the clapper 11 is sucked and the tip of the clapper 11 moves in an arc around the hinges 11b, 11b, the discharge plate 21 moves forward while maintaining the substantially original perpendicular state with respect to the base plate 22. be able to.

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

In the above description, the discharge plate 21 is positioned substantially immovable up and down by setting the height of the legs 21b, 21b slightly smaller than the maximum height h of the square hole 22a. (Figure 5). Furthermore, 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 can be made substantially immobile in any direction in a plane parallel to the base plate 22. Can be done.

[0025]

As explained above, according to the present invention, a discharge plate and a solenoid are provided, and the discharge plate and the clapper of the solenoid are connected so that the relative angle can be changed, so that the discharge plate can be attached to the base plate. The abnormal medal can be ejected by moving forward while maintaining the original perpendicular state, and at this time, there is no room for harmful gaps to form on the top surface of the ejection plate, so the medals will not get caught in the gap. There is no risk of malfunction due to being inserted, and there is an excellent effect that abnormal medals can be reliably ejected.
