Description

  The present invention relates to a power supply device for a gaming machine used for a gaming machine such as a pachislot machine or a pachinko machine.

Conventionally, gaming machines such as pachinko machines and pachislot machines have a game setting switch and a power switch that change settings such as the payout rate and payout rate in the power supply device in the main body, and the clerk opens the game panel on the front of the main body. It is configured so that it can be operated.
If this power switch or game setting switch is operated illegally, it will lead to a decrease in sales at the game hall.

  In order to prevent this fraud, a power supply device for a gaming machine has been proposed that includes a game setting switch and a protective cover for protecting the power switch on the front surface of the power supply device (see Patent Document 1).

  In the power supply device of this gaming machine, the protective cover is configured to be openable and closable, and the protective cover is always urged in the closing direction to prevent the protective cover from being forgotten to be closed. In addition, improper behavior is prevented by fixing with a stopper having a latch structure.

  As another method, a gaming machine including a game setting switch and an independent locking device has been proposed (see Patent Documents 2 and 3). This gaming machine prevents fraud by requiring a two-step operation to change the setting.

  However, although these methods are useful for preventing fraud, the workability of the game hall staff has not been considered.

  That is, in the method of always urging the protective cover in the closing direction, the clerk has to open the protective cover with one hand, change the setting with the other hand, and use both hands. Even if the protective cover is opened with one hand and an attempt is made to quickly change the setting, the protective cover will turn in the closing direction and hit the hand whose setting is being changed.

  Further, the method requiring two-step operation has a problem that the working time becomes long. Further, when two locking devices are provided, the number of locking devices that are usually the most expensive components among the components constituting the power supply device increases, which is not practical from the viewpoint of cost.

  In view of the above-mentioned problems, the present invention provides a power supply device for a gaming machine that protects a power switch and a game setting switch provided in a power supply device of a gaming machine from fraudulent acts and does not reduce the workability of a staff member. The goal is to improve the satisfaction of hall managers and staff.

  The present invention provides a power supply device for a gaming machine that includes a power switch operated by an attendant and a game setting switch on the front surface of a main body case, and an openable protection cover that protects the power switch and the game setting switch. If the protective cover is closer to the closing direction than the predetermined position of the opening / closing operation, the protective cover is biased in the closing direction, and if the protective cover is closer to the opening direction than the predetermined position, the protective cover is biased in the opening direction. It is a power supply device for game machines provided with the opening-and-closing biasing means to perform.

The predetermined position includes a position where the opening / closing biasing means is neutral.
The opening / closing of the protective cover includes opening / closing by swinging or opening / closing by sliding.

  The opening / closing biasing means includes a biasing portion and a cam portion in the vicinity of the opening / closing pivot when opening / closing by swinging. In the case of opening and closing by sliding, the longitudinal direction (or the width direction) becomes the sliding direction with the center-shaped convex spring facing the protective cover side with a hemi-shaped leaf spring (biasing portion) on the main body case side. And a protective cam having a convex cam portion that slides while being biased by the leaf spring during opening and closing.

  According to the above configuration, when the clerk opens the protective cover above a predetermined position, it naturally moves in the opening direction and maintains the open state, and when it closes above the predetermined position, it moves naturally in the closing direction and maintains the closed state. it can.

  Therefore, the protective cover can be stopped in the open state, and the staff can comfortably operate the power switch and the game setting switch. Further, when the protective cover is closed, the protective cover moves from the predetermined position in the closing direction to be in a completely closed state, and it is possible to prevent a state in which the protective cover is not closed and a gap is left open.

  As an aspect of the present invention, the protective cover is pivotally attached to the main body case and opened and closed by swinging, and the opening / closing urging means includes an urging portion provided on the main body case side in the vicinity of the opening / closing pivot, and It can comprise with the cam part which contacts the urging | biasing surface of the said urging | biasing part in preparation for the said protective cover side of the pivot vicinity.

  The urging portion is configured by a plate spring as a whole including the urging surface, or an appropriate member (resin member, metal member, etc.) that forms the urging surface is a spring (plate spring, coiled spring, etc.) ).

  The cam portion includes forming with an appropriate member such as resin or metal, and includes forming the cam portion integrally with the protective cover or attaching the cam portion to the protective cover.

  With this configuration, the protective cover can be urged to open and close with a simple structure and low cost.

  Further, as an aspect of the present invention, when the protective cover is positioned at the predetermined position of the opening / closing operation, the urging force is a straight line connecting a contact point with the urging surface and the opening / closing pivot. It can be disposed at a position perpendicular to the surface direction of the surface.

  Thereby, it is possible to reliably perform switching at a predetermined position between the biasing in the opening direction and the biasing in the closing direction.

  As an aspect of the present invention, the predetermined position can be set to a position where the protective cover is opened about 45 ° from the closed state.

  Thereby, the clerk can easily open and close the protective cover by an easy-to-familiar operation, and convenience is improved. That is, in general, the angle recognized when the protective cover is opened is larger than about 45 °, and the angle recognized when the protective cover is closed is smaller than 45 °. For this reason, if the protective cover is opened and closed with the ordinary sense of ordinary people, it will shift to the fully open state or the fully closed state, and can be used naturally with an easy-to-understand sense.

Further, as an aspect of the present invention, a plurality of the opening / closing urging means can be disposed in the axial direction of the opening / closing pivot of the protective cover.
Thereby, the urging force at the time of opening and closing can be dispersed, and the opening and closing of the protective cover can be urged stably.

  According to the present invention, it is possible to prevent unauthorized use of the power supply device for gaming machines without deteriorating the workability of the staff.

As shown in FIG. 3, the power supply device 11 is configured by pivotally attaching a cover door 20 to a main body 40 with a pivot 35.

  The cover door 20 is formed in a vertically long rectangular plate shape having a periphery and covering the switches. The cover door 20 is provided with a mounting groove 22 for attaching the bent end portion 35a of the pivot 35 on the left end surface thereof, and two cams 24 passing through the pivot 35 are disposed vertically below the mounting groove 22.

  In addition, a groove is cut in the central part of the left end of the cover door 20 and the lower part of the left end so as to fix the hinge part composed of the pivot 35, the pivot holding arms 41, 44, 45, 49 (FIG. 4) and the cam 24. Yes. A handle 21 is attached to the front right side (the left rear side in the figure) of the cover door 20.

  The main body 40 is a combination of a metal chassis 40a that houses a power supply board that supplies the gaming machine 1 with output voltage and power that are defined with an AC voltage as an input, and a metal chassis 40b that covers the entire power supply board. The whole is formed in a box shape.

  On the front left side of the chassis 40a, as shown in FIG. 4, pivot holding arms 41, 44, 45, 49 for receiving the pivot 35 are cut and raised to the front side in a square shape when viewed from the bottom. Are arranged side by side in the vertical direction. The pivot holding arms 41, 44, 45, and 49 are alternately formed in the right and left directions to suppress backlash of the hinge portion.

Further, between the pivot holding arms 41, 44, 45, and 49, pivot guides 42, 46, and 48 for pivotally guiding the pivot 35 are cut and raised at right angles.
Between the pivot guide 42 and the pivot holding arm 44, and between the pivot guides 46 and 48, two plate springs 31 are respectively attached and attachment holes 43 into which the cams 24 are inserted are formed.

  Embossing (not shown) and claws sandwiched by cutting and raising are formed inside the mounting hole 43, and the leaf spring 31 is configured to be attached to the main body 40 without using screws.

  The leaf spring 31 is a plate-like body that is bent in the center in a plan view, and is formed of a metal member having elasticity. The mounting portion 32 constituting one of the bent portions is formed with a bent raised portion 32a whose end is bent slightly for mounting to the chassis 40a, and an mounting hole 32b for mounting, and is fixed to the chassis 40a. . The other of the bent portions is in a free state after attachment, and constitutes a biasing portion 33 that biases the cam 24 by its elastic force.

  In addition, a power switch 54, a reset switch 57, and a setting switch 58 are provided on the front surface of the chassis 40a as switches that allow a specific operation. Also, an input confirmation LED 53 indicating the input state of the power supply and an output confirmation LED 56 for confirming the output of the output voltage are provided.

The power switch 54 is a seesaw switch and allows switching of power ON / OFF.
The reset switch 57 is a push button switch that allows the gaming machine 1 to be reset and recovers an error state or the like of the gaming machine 1 by the reset.

The setting switch 58 is a key-type switch that is mounted via a harness, and allows a setting change of the payout rate of the gaming machine 1 by inserting and rotating the key.
The power switch 54, the reset switch 57, and the setting switch 58 are protected by the cover door 20 from being tampered with.

  Further, a locking hole 55 is also provided on the front surface of the chassis 40a. The locking hole 55 is a hole in which the front end of the handle 21 attached to the cover door 20 is latched, and is locked so that the cover door 20 is not easily opened by the latch structure.

On the plane of the chassis 40b, holes for the output connectors 61, 62, 63, 64 are formed, and a plurality of heat radiation holes 68 for heat radiation are formed side by side by cutting down. The heat radiating hole 68 has an effect of preventing dust from entering as compared with a case where the hole is simply opened, and has an effect of preventing injury due to burrs during work, compared to the heat radiating hole formed by cutting and raising.
In addition, a plurality of long-hole-shaped heat radiation holes 69 for heat radiation are formed below the right side surface of the chassis 40b.

As shown in the enlarged sectional plan view of FIG. 5, the cam 24 is formed in a substantially rhombus shape in plan view on the left end side of the cover door 20, and a shaft hole 24 c is formed so that the pivot 35 can be inserted.
More specifically, in the closed state shown in the figure, the rear side portion of the pivot 35 is formed in a mountain shape, and a semi-cylindrical columnar protrusion 24a is formed at the tip thereof.
The left end of the chevron is folded at a right angle to form a stop projection 24b.

  With the above configuration, when the clerk grasps the handle 21 and opens the cover door 20 to some extent, the cover door 20 is opened to the fully open position by the urging force that the leaf spring 31 urges the cam 24 thereafter. When closing the cover door 20, if the clerk closes to some extent, then the cover door 20 is closed to the fully closed position by the urging force that the leaf spring 31 urges the cam 24.

  More specifically, as shown in the enlarged sectional plan view of FIG. 5, in the fully closed position where the cover door 20 is closed (the angle θ = 0 ° formed by the front of the cover door 20 and the main body 40), the columnar shape of the cam 24. The protrusion 24a is in contact with the biasing surface 33a of the leaf spring 31 at the contact point P1.

  When a perpendicular line of the urging surface 33a is drawn from the contact point P1, the axis of the pivot 35 is located on the cover door 20 side (right side in the drawing) from the contact point P1. Accordingly, the direction in which the elastic force of the leaf spring 31 acts is opposite to the cover door 20 from the axis of the pivot 35 (outside the pivot 35 when viewed from the cover door 20), and biases the cover door 20 in the closing direction. It will be.

  At this time, by latching the front end of the handle 21 in the locking hole 55 of the chassis 40a, the locking force that maintains the closed state of the cover door 20 is strengthened, and illegal acts from the outside are prevented.

  When the cover door 20 is opened clockwise by removing the latch, as shown in the partial cross-sectional plan view of FIG. 6, 0 ° <θ <45 ° until θ = 45 ° which is the neutral position. During that time, an urging force is applied in the closing direction. At this time, as shown by an imaginary line, as the cover door 20 is opened, the apex (contact point P1) of the columnar protrusion 24a pushes up the urging surface 33a. Therefore, the urging force to be closed gradually increases.

  As shown in the partial cross-sectional plan view of FIG. 7, when the neutral position (θ = 45 °) is reached, the perpendicular of the urging surface 33a drawn from the contact point P2 of the columnar protrusion 24a passes through the axis of the pivot 35. It becomes. Therefore, the direction in which the elastic force of the leaf spring 31 acts is in line with the axis of the pivot 35, and the cover door 20 is not biased in either the closing direction or the opening direction.

  When the cover door 20 is further opened, as shown in the partial sectional plan view of FIG. 8, 45 ° <θ ≦ 90 ° is obtained beyond the top of the columnar protrusion 24 a of the cam 24. When the perpendicular of the urging surface 33a is drawn from the contact point P3 at this time, the axis of the pivot 35 is located on the opposite side (the left side in the drawing) to the cover door 20 from the contact point P1. Accordingly, the direction in which the elastic force of the leaf spring 31 acts is on the cover door 20 side (inside the pivot 35 when viewed from the cover door 20) with respect to the axis of the pivot 35, and strongly urges the cover door 20 in the opening direction. It becomes.

  When the cover door 20 is opened, the stop protrusion 24b provided on the cam 24 finally comes into contact with the urging surface 33a, thereby stopping the urging in the opening direction, and the cover door 20 is perpendicular. It will stop stably in the fully open state (θ = 90 °).

  That is, in this fully open state, the columnar protrusion 24a contacts the inside of the pivot 35 as viewed from the cover door 20, the stop protrusion 24b contacts the outside of the pivot 35 as viewed from the cover door 20, and the cam 24 is a plate. While being urged by the elastic force of the spring 31, a balanced state is achieved.

  When the cover door 20 is closed from the fully open state described above, the cover door 20 operates in the opposite direction to the operation in the open direction described above, and the cover door 20 is urged in the closing direction when the neutral position is exceeded and is completely closed completely. Will be.

  Thus, when the cover door 20 is opened, it is automatically fixed at an opening / closing angle of 90 °, so that the clerk can work in a comfortable environment without worrying about the cover door 20 hitting the hand. It can be carried out.

  When the cover door 20 is closed, the cover door 20 automatically and completely closes if the neutral position is exceeded. Can be prevented. Further, the time for opening and closing the cover door 20 can be shortened, and the working time can be shortened.

  Moreover, since the columnar protrusion 24a that contacts the biasing surface 33a of the leaf spring 31 is rounded by chamfering, it can be smoothly opened and closed without being caught in the middle.

Further, by inserting the pivot 35 into the cam 24, it is possible to stabilize the acting direction and the neutral position of the elastic force of the leaf spring 31 during the opening / closing operation.
Further, since it can be realized with a small number of parts, it is possible to prevent an increase in cost and improve the satisfaction of the user.

  In the above-described embodiment, the direction in which the elastic force of the leaf spring 31 acts is changed with 45 ° as a boundary. However, the position of the columnar protrusion 24a is changed as necessary to adjust the boundary angle to another angle. May be.

  Further, either one or both of the chassis 40a and 40b may be formed of a resin member. In this case, the cover door 20 can be easily assembled.

  Further, the switches on the front surface of the chassis 40a are not limited to the above configuration. For example, a medal collection switch for collecting game medals, an automatic settlement switch for setting the presence / absence of automatic process settlement processing, or a stop for setting presence / absence of a strike It is good also as a structure provided with appropriate operation switches, such as a switch, and protecting these with the cover door 20.
