DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply device comprising a plurality of control devices and a power supply board for generating a predetermined voltage based on an external power supply supplied from the outside and supplying the voltage to each control device. And a gaming machine comprising:

[0002]

2. Description of the Related Art Conventional gaming machines such as pachinko gaming machines include, for example, display systems, audio systems, (for decoration)
The system further includes a control device of a general control system that divides electric components according to systems such as light-emitting systems, controls the operation of these electric components by a separate control device for each class, and controls the control devices and the like of the respective systems. There is something.

On the other hand, power is supplied to the gaming machine from an island facility outside the gaming machine to a power supply device provided on a front frame of the gaming machine. The power supply device includes a power supply board that generates a predetermined voltage based on an external power supply supplied from outside the gaming machine and supplies the predetermined voltage to each control device. Further, the power supplied from the power supply board to each control device is supplied to the corresponding electric component for each system.

Here, in principle, only necessary types of power supply voltages are supplied from the power supply board to the respective control devices. That is, specifically, for example, in a certain control device, the DC 32
If V, DC12V and DC5V are required, the control unit is supplied with these three kinds of power supply voltages, and the other control units supply DC voltage.
If 12 V and 5 V DC are required, the controller

Some gaming machines have a backup area in a part of the memory for holding the contents of the memory (storage means) even when the power is turned off. By providing this backup area, even if power is not supplied due to power cutoff (for example, due to a power failure), a backup function is provided so that the previous game state can be stored. Note that the storage contents of the backup area include, for example, data necessary for restarting a gaming state such as a big hit state or a probability fluctuation state after power restoration.

[0006]

Here, in pachinko gaming machines, classifications such as so-called first type, second type, and third type, and model classification that is further subdivided than this type classification, etc., are used. There are many types. When the type of the electric component such as the solenoid or the lamp used differs for each type, the type of the necessary power supply voltage may differ accordingly. Therefore, in this case, the type of power supply voltage to be supplied from the power supply board to each control device differs for each type of gaming machine. That is, in this case, the type of power supply voltage to be generated by the power supply board differs for each type of gaming machine. The power supply board has a larger board area as the number of types of power supply voltages to be generated and the number of ports for power supply increase, so that the size of the power supply board for each type of pachinko game machine, Will be different.

However, in the conventional gaming machine, the power supply device to be originally mounted is limited to a specific size, so that another power supply device having a different size cannot be replaced with the front frame. Also, when changing to a different type of gaming machine when recycling the gaming machine or the like, the entire front frame must be replaced inevitably with the change of the power supply device, which is wasteful.

Further, an electromagnetic wave is generated from the power supply board of the power supply device, and this electromagnetic wave exerts an adverse effect on other electronic devices (for example, sensors provided in a game machine) such as inducing a malfunction. There is a problem that may be.

On the other hand, in the case of a gaming machine having a backup function, the contents stored in the backup area are retained even after the power is cut off at the end of the business hours of the game store. for that reason,
If the state is the probability fluctuation state or the big hit state at the end of the business hours, when the power is turned on on the next business day, the probability fluctuation state or the big hit state is suddenly started in the morning and the business is hindered. Therefore, in order to avoid this problem, a gaming machine provided with a reset switch (erasing operation unit) for erasing the storage contents of the backup area as necessary is considered. However, this reset switch is too easy to press (it is easy to operate carelessly)
If so, there is a possibility that an operation by force majeure may be performed. Specifically, for example, it is conceivable that the reset switch is pressed due to a game ball that has fallen on the reset switch for some reason, or that the reset switch is pressed by an unintended unintentional operation of a clerk. Can be Nevertheless, if the reset switch is provided with a lid to avoid operation of the reset switch due to force majeure, and after performing the work of opening this lid,
For the first time you can operate the reset switch,
There is a problem that operation is too troublesome. That is, it can be said that a gaming machine that balances the ease of pressing the reset switch with the difficulty of pressing the reset switch is desired.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. A power supply device having different dimensions can be mounted on a front frame, and furthermore, an adverse effect due to electromagnetic waves generated from a power supply board of the power supply device. It is an object of the present invention to provide a gaming machine capable of reducing the number of game machines. Still another object of the present invention is to provide a gaming machine having an erasing operation section and having a balance between the ease of pressing and the degree of difficulty in pressing the erasing operation section.

The power supply device 90 configured as described above
The front frame 111 is attached to the back side of the back mechanism board 120 via a plate member 96 made of a conductive material (for example, a conductive metal material).

As shown in FIG. 7, the plate member 96
A frame-side mounting portion 96a for mounting the plate member 96 to the front frame 111 (the back side of the back mechanism panel 120) and a power supply device mounting portion 96b for mounting the power supply device 90 to the plate member 96 are provided. I have. Of these, the frame-side mounting portion 96a is a mounting hole through which a fastening member such as a screw is inserted. On the other hand, the power supply device mounting portions 96b,... Are provided by fixing a power supply device (for example, the power supply device 90) selected from a plurality of types of power supply devices having different dimensions at a plurality of positions (for example, four positions). In order to be able to attach to 96, it is provided in more places than the plurality (four places), respectively. Specifically, for example,
The left and right edges of the plate member 96 are provided with a large number of power supply devices symmetrically from the upper portion to the lower portion so as to be attachable to any of a plurality of types of power supply devices having different dimensions in the vertical direction. .. Are provided. In the case of the present embodiment, the power supply device mounting portions 96b are connected to the power supply device 90 by a fastening member such as a screw 97 (FIG. 4).
The mounting hole is used to mount a hole, but the present invention is not limited to this. That is, for example, the power supply device 90 and the plate member 96
Or the power supply 9
The power supply device 90 may be attached to the plate member 96 by a fitting structure in which the 0 and the plate member 96 are fitted to each other. In this case, the power supply device mounting portion 96b is a locking portion or a fitting portion. For example, in FIG. 7, in a portion of the plate member 96 hidden by the power supply device 90, a large number of power supply device mounting portions 96 b,... Is also good.

The plate member 96 configured as described above
The attachment of the power supply device 90 using the method is performed as follows.

First, screw holes 98e of (for example, four) conductive members 98,...
Are aligned with the corresponding power supply mounting portions 96b,... Of the plate member 96, respectively. Furthermore, in this state,
The screws 97 are screwed into the screw holes 98e via the power supply mounting portions 96b to fix the power supply 90 to the plate member 96. As described above, the power supply unit 190 including the power supply 90 and the plate member 96 is configured. In this state, the ground electrode of the power supply board 94 is electrically connected to the plate member 96 via the conductive member 98.

Further, the power supply unit 1 thus configured
90 is the back mechanism board 12 of the front frame 111 as described below.
Attach it to the back of 0. First, with the plate member 96 positioned closer to the back mechanism board 120 than the power supply device 90, the screw 96c is screwed into the back mechanism board 120 via the frame-side mounting portion 96a of the plate member 96. Thus, the power supply device 90 is provided on the front frame 111 such that the conductive plate member 96 is interposed between the power supply device 90 and the front frame 111.

According to the pachinko gaming machine 100 of the first embodiment as described above, the conductive plate member 96 is interposed between the front frame 111 and the power supply device 90, so that the power supply device 90 An adverse effect on the front frame 111 side (electrical components attached to the front frame 111) due to electromagnetic waves generated from the power supply board 94) can be reduced. A power supply unit 190 constituted by attaching the power supply 90 to the plate member 96.
Is attached to the front frame 111, the power supply device 90 and the plate member 96 can be collectively attached as a unit, so that attachment is easy.

Further, the plate member 96 is provided at a plurality of places (for example, four places) to fix and attach any one of a plurality of kinds of power supplies having different dimensions. Since the power supply device mounting portion 96b provided at each of the multiple locations is provided, the selected power supply device 90 is mounted on the plate member 96 by fixing the selected power supply device 90 to the power supply device mounting portion 96b at any one of the multiple locations. The power supply unit 190 can be configured. In other words, an appropriate power supply device 90 can be selected from a plurality of types of power supply devices having different dimensions and attached to the plate member 96 to form the power supply unit 190. By attaching the power supply unit 190 to the front frame 111, the power supply The device 90 can be provided on the front frame 111.

Further, even if the power supply device 90 is replaced when the pachinko gaming machine 100 is changed to another type, the same plate member 96 is recycled to provide another power supply device on the front frame 111. Can be. At this time, in order to replace the power supply device 90, the power supply device 90 must be replaced by the front frame 111 for each plate member 96 (for each power supply unit 190).
After removing the power supply from the plate member 96, the power supply 90 may be replaced.

Further, the power supply device 90 is connected to the power supply mounting portion 9.
When the power supply board 94 is fixed, the ground electrode of the power supply board 94 is electrically connected to the plate member 96. Therefore, when the power supply board 94 is charged, it can be discharged to the plate member 96. As a result, the discharge area for air discharge is reduced by the plate member 9.
6, the air discharge can be efficiently performed in the air. In addition, the storage box 9 for storing the power supply board 94
Since 5 is made of a conductive material, the power supply board 94 can be electromagnetically shielded by the storage box 95, and the possibility that the electromagnetic waves generated from the power supply board 94 reach the outside of the storage box 95 can be reduced.

The power supply board 94 is provided with a RAM clear switch 94c for erasing the stored contents of the backup area 300.
By operating the M clear switch 94c, the contents stored in the backup area 300 can be erased.

Here, the contents stored in the RAM 21b backed up by the backup power supply circuit 91 are retained even after the power is cut off, for example, when the business hours of the game store are closed. In the case of a fluctuating state or a big hit state, when the power is turned on the next business day, the state suddenly changes to a probability fluctuating state or a big hit state in the morning, which hinders business. Therefore, normally, when the probability fluctuation state or the big hit state is at the end of the business hours, the RAM clear switch 94c is operated to
It is necessary to erase the contents stored in the RAM 21b. Also,
For example, when the data for discharging the prize ball is changed to an invalid data due to a wrongdoing, the prize ball which does not need to be paid out is paid out. In this case as well, the RAM clear switch 94c is operated to operate the RAM clear switch 94c. It is necessary to erase the contents stored in the RAM 31b. On the other hand, for example, when the power is cut off due to a power failure occurring during a normal (non-illegal) game, the RAM 21b,
It is necessary to hold the storage contents of the storage 31b. However, if the RAM clear switch 94c is too easy to press, operation by force majeure may be performed, and the stored contents of the RAMs 21b and 31b may not be retained until the power is restored. Specifically, for example, for some reason, the RAM clear switch 94
The RAM clear switch 9 is used for the game ball that has fallen toward "c" or by the unintended operation of the clerk.
4c may be pressed. However, if the RAM clear switch 94 due to force majeure
RAM clear switch 94c to avoid the operation of c
It is too cumbersome to operate the RAM clear switch 94c for the first time after the lid is provided and the operation of opening the lid is performed.

Under such circumstances, according to the present invention, the RAM clear switch 94c can be easily operated from outside the power supply device 90 through the opening 95c provided in the storage box 95. In addition, the storage box 95 has the opening 9
Since the projection 95f is provided so as to project outward of the power supply device 90 from the position 5c, the RAM clear switch 94c can be prevented from being operated by force majeure.
In other words, the pachinko gaming machine 100 achieves a balance between the ease of pressing and the difficulty of pressing the RAM clear switch 94c.

In the first embodiment, the position of the projection 95f is the upper part of the opening 95c.
The present invention is not limited to this, and may be a peripheral portion (either up, down, left, or right) of the opening 95c. Although the example in which the pressing direction of the RAM clear switch 94c is the horizontal direction has been described, the pressing direction is arbitrary, and the protruding direction of the protruding portion 95f can be appropriately changed corresponding to the pressing direction (pressing direction). And the projecting directions are desirably made to substantially coincide with each other). Furthermore, the first half housing part 95a constituting the storage box 95
Although both the first and second half-housing portions 95b are made conductive, the present invention is not limited to this, and only one of the two half-housing portions 95a and 95b (for example, the half-housing portion 95a only)
May be conductive.
