Description

[0001]
[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing fraud in a gaming machine such as a pachinko machine, which prevents fraud.
[0002]
[Prior art]
As is well known, various gaming machines such as pachinko machines are provided with various prize holes and display devices on the game board in order to improve the playability, and are particularly referred to as first and third types. Some pachinko machines have a special winning opening called a starting opening, which is equipped with a sensor, such as a microswitch, that detects the ball that has entered the starting opening. When this is done, a detection signal is sent to a microcomputer built in the gaming machine, and the microcomputer controls a variable display device and accessories on the gaming board so as to correspond to the special winning.
[0003]
[Problems to be solved by the invention]
However, in a conventional gaming machine, a piano wire or the like is inserted into a game board surface through a gap in a front decorative frame to cause the above-described sensor to malfunction, and a variable display device or a role playing device is intentionally deemed as if a special prize has been won. Unjust acts such as controlling things were performed.
[0004]
As a means for preventing such misconduct, Japanese Utility Model Laid-Open Publication No. 57-128883 discloses a technique of providing a security shield plate at the upper edge of a front panel of a pachinko machine. However, according to the method disclosed in the present invention, in order to cover all the gaps in the front plate, the blocking plate becomes large, and in order to newly provide a special member called a blocking plate, a pachinko machine is required. This leads to problems such as an increase in manufacturing steps and manufacturing costs.
[0005]
[Means for Solving the Problems]
The present invention has been made in view of the above, and a frame-shaped front frame having a window is hinged to the outer frame so as to be openable and closable, and a frame having a window is provided on the front side of the front frame. A front plate is attached to the front frame so that it can be opened and closed, and a glass frame with glass is attached to the back side of the front frame so that it can be opened and closed. In the gaming machine facing the game board so as to cover the window portion of the front frame, the game board is provided with a decorative member integrally molded in a shape to cover the game board, A band-shaped protrusion is integrally provided on the outer periphery of the decorative member, and the glass frame is formed with a peripheral portion and an L-shaped engaging portion that protrudes in a band shape from the peripheral portion. In a state where the glass frame is closed, the protrusion of the decorative member is provided in a gap generated between a peripheral portion of the glass frame and an engagement portion. Characterized by being adapted to fit.
[0009]
[Action]
By forming the members constituting the anti-fraud device integrally with the existing glass frame and decorative member, it is possible to prevent fraud without increasing the manufacturing process and manufacturing cost of the gaming machine.

On the other hand, at the lowermost part of the inner guide rails 51b provided on the left and right facing the game section 52, the out port 53 is formed integrally with the decorative member 5a, and as shown in FIG. An out hole 52a for discharging a ball is provided in a portion of the game board 5 corresponding to the out port 53. At the lower part of the out port 53, for example, the metal plate 51c provided on the inner guide rail 51b is extended and integrally molded. As a result, the strength of the out port 53 is increased, and the out port 53 can sufficiently withstand the impact of the ball dropped from the game section 52.
[0021]
FIG. 10 is a view according to one embodiment of the present invention. FIG. 3 is a longitudinal sectional view in a state where the glass frame 14 is closed with respect to the game board 5 in FIG. 3, and FIG. It is a part enlarged view.
The fraud prevention device according to this embodiment generally includes, when the glass frame 14 is closed with respect to the gaming board 5, a peripheral portion 14 c of the glass frame 14, which is a first member, and an integral part of the peripheral portion 14 c. And the protrusion 5c formed integrally with the decorative member 5a, which is the second member to be fitted with the peripheral portion 14c and the engagement portion 14d. It prevents the intrusion of a piano wire or the like into the gaming section 52 surrounded by the guide rail section 51 and the glass 14b on the gaming board 5.
[0022]
In this embodiment, in a state where the glass frame 14 is closed with respect to the game board 5 as shown in FIG. 10, as shown in FIG. 11, a peripheral portion 14c of the glass frame 14 and a belt-like shape are formed from the peripheral portion 14c. The gap formed between the engaging portion 14d having a substantially L-shaped cross section and being fitted to the band-shaped projecting portion 5c formed integrally with the substantially outer peripheral portion of the decorative member 5a. The glass frame 14 functions as a holding member that holds the glass frame 14 as well as the fraud prevention device.
In the state in which the glass frame 14 is closed with respect to the game board 5, the fraud prevention device allows the gap between the decorative member 5a and the glass frame 14 to be in contact with the engaging portion 14d, as can be seen from FIG. The projecting portion 5c and the peripheral edge portion 14c have a structure that is bent four times in the cross-sectional direction, and even if an attempt is made to insert something into the gap, it is always blocked at the bent portion and passes through the gap. It becomes impossible.
As a result, it becomes impossible for a piano wire or the like to enter the gaming section 52, and it becomes possible to prevent illegal acts in a gaming machine such as a pachinko machine.
In this embodiment, the engaging portion 14d is integrally formed of the same material as that of the glass frame 14. However, the engaging portion 14d is made of a different material, for example, a metal such as iron, and has a substantially L-shaped cross section. May be formed in advance, and then the frame may be formed integrally with the glass frame 14 so as to protrude from the peripheral edge portion 14c to form the engaging portion 14d.
[0023]
In the embodiment of FIG. 11, the metal plate 51c is inserted into the lower projecting portion 5c so as to straddle the decoration member 5a main body. By this reinforcement, even when the glass frame 14 is closed, the projecting portion 5c can securely hold the glass frame 14.
[0024]
As described above, the present invention has been described with reference to the illustrated embodiment. However, the present invention is not limited to the above-described embodiment, and can be appropriately implemented unless the configuration described in the claims is changed.
[0025]
【The invention's effect】
As described above, according to the present invention, a frame-shaped front frame having a window is hinged to the outer frame so as to be openable and closable, and a frame-shaped front decoration frame having a window is provided on the front side of the front frame. Attached to be able to open and close freely, a glass frame fitted with glass is attached to the back side of the front decoration frame so as to be openable and closable, and on the back side of the front frame, a rear plate for detachably storing a game board is provided, In a gaming machine having a game board facing a window of a front frame, a decoration member integrally formed in a shape covering the game board is provided on the game board, and an outer periphery of the decoration member is provided. The glass frame is formed integrally with the glass frame, and the glass frame is formed with a peripheral portion and an engagement portion having a L-shaped cross section that protrudes in a band shape from the peripheral portion. In the closed state, the protrusion of the decorative member fits into the gap generated between the peripheral portion of the glass frame and the engagement portion. By the, there is no need to provide a member for new fraud prevention, has the effect of this without increasing the manufacturing steps and the manufacturing cost of the gaming machine by, prevents fraud.
