Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an illegal unlocking prevention device for a game machine.

[0002]

2. Description of the Related Art Generally, a pachinko machine 1 has a structure in which a machine frame 4 to which a game board is attached is attached to an outer frame 3 via a hinge so as to be able to open one side (see FIG. 14). Machine frame 4
Is provided with a hook member 5 on the open end side, and when the machine frame 4 is closed, the hook member 5 is locked to the locking projection 2 provided on the outer frame 3 to hold the machine frame 4 in the closed state. . When the machine frame 4 is opened, the operation is performed by inserting a key into a key hole provided on the front surface of the game board. Then, the hook member 5 moves in the unlocking direction by the operation of the internal cylinder lock, and the locking of the locking projection 2 is released.

However, when the engaging portion between the hook member 5 and the engaging projection 2 is exposed, if a wire-like instrument with a bent tip is inserted from the gap between the adjacent pachinko machines 1, the hook member will be removed. Since the release operation can be performed, it gives an opportunity of an illegal act of illegally opening the machine frame.

As a countermeasure, for example, Japanese Patent Laid-Open No. 2001-2
Something like 24812 has been developed.
As shown in FIG. 15, this is configured such that the hook member 5 is vertically moved and hooked on the locking projection 2 provided on the outer frame 3. In this state, the unauthorized device can be released from the gap between the adjacent pachinko machines by advancing it in the direction of the arrow shown in the figure and pushing down the hook member 5 from the rear of the outer frame 3. Therefore, in this case, a protective cover 6 having a back wall 6A is attached to the outer frame 3 so as to surround the locking portion of the hook member 5.

[0005]

By the way, it may be desired to open the machine frame before the pachinko machine is installed on the "island". In such a case, if the protective cover 6 is not provided, the hook member 5 can be directly operated by hand to easily perform the unlocking operation. However, in the case where the protective cover 6 is attached, since the protective cover 6 is firmly attached to the outer frame 3 by means such as screw tightening, it is easy to directly release the hook member 5. Not. Therefore, conventionally, it was troublesome to use a key to operate the cylinder lock.

The present invention has been made in view of the above circumstances, and an object thereof is to prevent unauthorized unlocking in a gaming machine in which even a protective cover can be easily unlocked. To provide a device.

[0007]

In order to achieve the above-mentioned object, the invention of claim 1 is such that a machine frame provided with a game board is attached to an outer frame by a hinge so that the machine frame can be opened. A lock portion is displaceably attached to the free end side edge of the frame, while the lock portion is locked to the outer frame to hold the machine frame in a closed state with respect to the outer frame. A lock receiving portion is provided, and a protective cover for covering the lock portion between the lock portion and the lock receiving portion is provided on either the outer frame or the machine frame when the machine frame is closed. An unauthorized unlocking prevention device comprising:
The protective cover can be held in a state of covering the locking portion via a fixing means that is detachable from the outer frame or the machine frame, and the protective cover is unlocked by the fixing means. When the protective cover is opened, a part or all of the protective cover is displaceable so that the locking portion is exposed.

According to a second aspect of the present invention, in the first aspect, the fixing means has a hooking claw provided on the protective cover, and the hooking claw is provided on the locking receiving portion. It is characterized in that it is engaged and disengaged with respect to it.

According to a third aspect of the present invention, in the first or second aspect, the protective cover has a mounting piece that can be fixed to the machine frame or the outer frame, and the mounting piece is a hinge. The locking portion can be exposed by rotating the protective cover about the hinge.

A sliding edge is formed so as to slidably lock and move the protective cover from a position covering the locking portion to an exposed state.

[0012]

<Advantageous Effects of the Invention><Invention of Claim 1> According to the invention of Claim 1, since the locking portion between the lock portion and the lock receiving portion is always covered with the protective cover, an illegal solution is obtained. Even if you try to operate the lock, you cannot perform the unlock operation because the protective cover disturbs you. Therefore, it is possible to effectively prohibit the situation where the machine frame is unlawfully opened.

Further, if the locking of the fixing means is released when necessary, the protective cover can be partially or wholly displaced, whereby the locking portion between the lock portion and the lock receiving portion can be exposed. it can. Thus, since the locked state by the lock portion can be released directly, the releasing operation by the dedicated key is not required and the usability is excellent.

<Invention of Claim 2> According to the invention of Claim 2, the protective cover covers the locking portion between the lock portion and the locking receiving portion by locking the hooking claw to the locking receiving portion. Keep it up. At this time, since the hooking claw is engaged with the hook receiving part which is an existing structure, it is not necessary to specially set a dedicated member for locking the hooking claw.

<Invention of Claim 3> According to the invention of Claim 3, the protective cover is attached to the machine frame or the outer frame by a mounting piece. When the locking of the fixing means is released when necessary, the protective cover rotates around the hinge to expose the locking portion between the lock portion and the lock receiving portion, enabling unlocking.

<Invention of Claim 4> According to the invention of Claim 4, the protection cover is mounted as a whole by locking the locking claws to the locking tool provided on the outer frame.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings.

<First Embodiment> A first embodiment of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 1 is an outer frame of a pachinko machine, and a machine frame 2 is attached to one end of the outer frame by a hinge h so that the machine frame can be opened. A game board equipped with various winning devices is attached to the machine frame 2,
A mechanism plate 3 provided with a prize ball payout device and the like is attached to the back side thereof. Further, a locking device provided with a hook member 4 (corresponding to the lock portion of the present invention) is vertically arranged at the edge of the machine frame 2 on the open side. The locking device has an operating rod 5 formed in the shape of a long piece, and hook members 4 are arranged at the upper and lower ends thereof. The hook member 4 projects rearward from the operating rod 5 at a substantially right angle, and has a tapered surface 6A at the tip.
The hook portion 6 in which is formed is formed. Both hook members 4
Makes it possible to lock the machine frame 2 by locking with a locking metal fitting 7 (corresponding to a locking receiving portion of the present invention) arranged at a position opposed to the inner surface of the outer frame 1.

Although not shown in detail, a biasing force of a spring acts on the operating rod 5, whereby the operating rod 5 is biased to lock the hook member 4 to the locking metal fitting 7. It Further, a cylinder lock c is provided on the open end side of the machine frame 2, and the operating rod 5 is arranged to displace the hook member 4 in the unlocking direction by inserting the key k into the cylinder lock c and operating the key. Can be activated.

The locking metal fittings 7 for both the hook members 4 are attached to the inner surface of the outer frame 1 by screws or the like, and a locking receiving piece 8 is bent and formed at one side edge thereof, and a hook is provided at the lower edge thereof. The hook portion 6 of the member 4 is detachable.

A protective cover 9 for covering the engaging portion between the hook portion 6 of the hook member 4 and the engaging receiving piece 8 is provided at a position adjacent to the engaging metal fitting 7 on the rear edge of the outer frame 1. It is installed. The protective cover 9 is composed of a mounting piece 10 for mounting on the outer frame 1 and a cover portion 12 continuous with the mounting piece 10 via a hinge edge 11, and is integrally formed of a synthetic resin material. The protective cover 9 is attached as a whole by fastening the mounting piece 10 to the rear edge of the outer frame 1 with a screw. The cover 12 has a back wall 12A continuous with the hinge edge 11, and a ceiling wall 12B and a bottom wall 1 above and below the back wall 12A.
2C are continuous, and the side wall 12D is continuous between them. Further, a hooking claw 13 (which constitutes the fixing means of the present invention together with the locking receiving piece 8) is provided at the center of the edge of the side wall 12D. A taper-shaped guide surface 13A is formed at the tip of the hooking claw 13, and is brought into sliding contact with the side edge portion of the lock receiving piece 8 of the lock fitting 7 as the protective cover 9 is closed. The guiding operation of the hooking claw 13 is guided, and the closed state of the protective cover 9 is maintained after the locking.

Next, the function and effect of the first embodiment configured as described above will be specifically described. When the key k is inserted into the cylinder lock c and the unlocking operation is performed in a state where the machine frame 2 is closed with respect to the outer frame 1, the operating rod 5 is displaced downward against a spring (not shown). . As a result, the engagement between the hook portion 6 of the hook member 4 and the engagement receiving piece 8 is released, so that the machine frame 2 can be opened.

By the way, for example, an illegal instrument is inserted from a gap between the adjacent pachinko machines 1, and the hook member 4 and the lock receiving piece 8 of the lock fitting 7 are unlocked from the rear side of the outer frame 1. Even if tampering is performed, the back wall 12A of the protective cover 9 prevents the tip of the illicit instrument (for example, a wire) from reaching the engaging portion between the hook member 4 and the engaging receiving piece 8. The machine frame 2 will not be unlawfully opened.

On the other hand, as described above, there is a demand to open the machine frame 2 from the outer frame 1 before the pachinko machine is installed on the "island", for example. In such cases,

Both of the guide rails 22 are formed by bending the upper and lower edges of the board 21 inward along the length direction, and when mounted on the outer frame 1, a gap is formed between the guide rail 22 and the outer frame 1 along the width direction. Are being held.

On the other hand, the protective cover 23 of this embodiment is the first
Unlike the embodiment, the side wall 23B is also provided on the surface facing the side wall 23A provided with the hooking claw 24 (the surface facing the inner surface of the outer frame 1 at the time of mounting). The central portion of the side wall 23B is notched so as to open forward with a width substantially equal to the vertical width of the locking fitting 20.
The upper and lower opening edges of the cutout portion 25 serve as slide edges 26 that can be slidably contacted with both guide rails 22.

According to the second embodiment having the above-described structure, both the sliding edges 26 of the protective cover 23 are locked to the locking metal fittings 20 while the hook member 4 and the locking receiving piece 8 are locked.
The guide rails 22 are locked and pushed in. Along with this sliding operation, the hooking claw 2 is automatically
4 is locked to the side edge of the lock receiving piece 8. Thus, the protective cover 23 is held in the closed state and protected from unauthorized unlocking operation.

In order to release the engaging portion of the hook member 4, the engagement of the hook claw 24 with respect to the engagement receiving piece 8 is released.
If the entire protective cover 23 is slid in the opposite direction to the above, the protective cover 23 can be removed from the locking metal fitting 20 while being guided by the guide rail 22, and then the hook member 4 and the locking receiving piece 8 can be removed. If the lock is released, the machine frame 2 can be opened.

The rest of the configuration is the same as that of the first embodiment, so that the same effect can be obtained.

<Third Embodiment> FIGS. 11 to 13 show a third embodiment of the present invention. In both the first and second embodiments, the locking metal fitting 7 is used to hold the protective covers 9 and 23 in the closed state, but in the third embodiment, the protective cover 30 is held by the locking metal fitting 31.
