Description

[Detailed description of the invention] This invention is a pachinko machine locking system that allows you to open the glass frame or open the front frame by inserting a key into the keyhole of the locking member provided on the front frame and rotating it. The present invention relates to a device, and particularly to a fraud prevention device for a pachinko machine that prevents unauthorized unlocking of a locking device from the outside.

Insert the key from the outside front of the pachinko machine and rotate the key in one direction to unlock and open the glass frame, or rotate the key in the other direction to unlock and open the front Pachinko machine locking devices that allow the frame to be opened are becoming popular. The structure of such a locking device is that a lifting rod that moves up and down with the rotation of a key is installed vertically on the back of the free side of the front frame, and the glass frame and front frame are unlocked by moving the lifting rod up and down. In most cases, there is a plate piece in the middle of the lifting rod to transmit the movement of the locking member or to unlock the glass frame without operating the key after opening the front frame. It is installed horizontally.

Furthermore, there is a vertical gap between the abutting surfaces of the machine frame and the front frame of the pachinko machine, which is caused by warping of the front frame or by defects in the hinge, locking device, etc.

For this reason, fraudulent acts such as inserting a piano wire, iron plate, etc. into the space between the ends and manipulating the plates of the lifting rod to open the glass frame continue to occur.

Therefore, in the present invention, a manually operable opening lever that extends backward from the middle of the length of the interlocking rod that locks and unlocks the glass frame is inserted between the contact surfaces of the machine frame and the front frame. The locks had been illegally unlocked using unauthorized parts such as piano wire and iron plates inserted from the inside, and fraudulent acts had been carried out, such as opening the glass frame and manually inserting a ball into the winning device on the game board inside. In view of this, especially since the base end of the opening lever is located at the boundary between the machine frame and the front frame, it is easy to come into contact with unauthorized parts, and it is easy to aim because the operating stroke required to unlock the locking device is small. Focusing on this point, a protective wall is provided that covers at least the proximal end of the opening lever and has an internal space that does not interfere with the operation of the opening lever, so as to prevent the unauthorized member from coming into contact with the opening lever. It is characterized by a protective wall that prevents unauthorized unlocking of the glass frame by unauthorized members.

Hereinafter, an embodiment of the present invention will be explained based on the drawings.

As shown in FIG. 1, the pachinko machine 1 includes a rectangular machine frame 2 with open front and rear sides, a frame-shaped front frame 3 hinged to one side of the machine frame 2 so as to be openable and closable, and a window on the front frame 3. It consists of a glass frame 4 hinged to one side so that it can be opened and closed, and a game board (not shown) with a game part provided on the surface facing the window 5 of the front frame 3. Therefore, when the glass frame 4 is closed to the window of the front frame 3, and the front frame 3 is closed to the machine frame 2 and locked by the locking device 6, the player can see through the glass of the glass frame 4 and play the game. You can play the game while watching the section.

Consists of pins 20, etc., and interlocking rods 18
Opening lever 2 extended rearward from the middle of the length of
1 engages with the lower surface of the protrusion 22 of the slide plate 17. The base end of the opening lever 21 that protrudes backward from the interlocking rod 18 is formed on one side of the edge frame 3a provided on the back side of the front frame 3 so as to hold a game board (not shown) at a constant distance from the front frame 3. It is fitted into the notch 3b. One side of the opening of the notch 3b faces the side surface of the board 8, and a peripheral wall surrounded by the notch 3b and the side surface of the board 8 faces the base end of the opening lever 21.
It serves as a protective wall having an internal space that does not impede the vertical movement of the opening lever 21.

In addition, here, a protective member 23 having a U-shaped cross section is further included.
is attached to the board 8, the back of the protective member 23 is directed between the machine frame 2 and the front frame 3, and the operating part of the free end of the opening lever 21 is used as a protective wall. A protective wall is provided along the entire length of the

In the glass frame locking mechanism having such a configuration, when the free side of the glass frame 4 is pressed against the window portion of the front frame 3, the hook portion 19 of the interlocking rod 18 descends, and the hook portion 1
A receiving pin 20 is engaged with the stepped portion 19' of 9 to lock the glass frame 4. Note that in the glass frame 4, the spring 24 connected to the opening lever 21 always urges the hook portion 19 in one direction (upward in the illustrated embodiment) and locks the hook portion 19 and the receiving pin 20, so that the interlocking lever 1
8 remains locked unless moved in the unlocking direction.

To unlock and open the locked glass frame 4, the key 15 inserted into the lock member 7 is rotated to the left (counterclockwise, opposite to when the front frame 3 is opened). When the key 15 is rotated in this direction, the rotation plate 12

When the slide plate 17 is lowered, the protrusion 22 that engages the opening lever 21 from above through a long hole 26 formed in the base plate 8 presses the opening lever 21 downward, and the interlocking rod 18 is lowered. When the interlocking rod 18 is lowered, the hook portions 19 at the upper and lower ends are lowered and removed from the receiving pins 21. Receive pin 21
When the hook portion 19 is released, the glass frame 4 becomes rotatable about the hinge and can be opened freely by hand.

In this case, even if you try to open the glass frame 4 by inserting a piano wire or iron plate through the vertical gap between the front frame 3 and the machine frame 2 and operating the opening lever 21, the piano wire, etc. The tip of the unauthorized member is blocked by the protective wall and is prevented from coming into contact with the opening lever 21. That is, since the base end of the opening lever 21 is covered by the notch 3b of the edge frame 3a and the base plate 8,
The tip of the unauthorized member is blocked by the base plate 8, and since the operating portion of the opening lever 21 is covered with the protective member 23, the tip of the unauthorized member is blocked by the protective member 23. Therefore, the glass frame 4 remains locked, and unauthorized members can prevent the glass frame 4 from being unlocked, thereby preventing fraudulent actions (for example, opening the glass frame 4 and hitting the ball into the winning device on the game board). It is possible to prevent the act of manually inserting the

FIG. 4 shows another embodiment of the protective member,
In addition to the proximal end of the opening lever 21 of the embodiment described above, a cylindrical protection member 23 is attached laterally to the board 8, and the opening lever 21 is installed inside the protection member 23.
The operation part of the opening lever 21 is used as a protective wall. This protective member may be made of metal or synthetic resin, or may be formed integrally with the substrate.

In the embodiment, the protective wall covering the base end of the opening lever 21 is formed by the notch 3b of the edge frame 3a and the base plate 8, but the present invention is not limited to this. A horizontal through-hole may be opened, and the base end of the opening lever 21 may be inserted into the through-hole, and the peripheral wall on the inner surface of the through-hole may be used as a protective wall. Any configuration may be used as long as it prevents the unauthorized member inserted from the contact surface from coming into contact with at least the base end of the opening lever 21. Therefore, it is of course possible to have a configuration that does not include the protective member of the embodiment, but in the embodiment, the protective member is attached to form a protective wall along the entire length of the opening lever. There is no possibility of contact with unauthorized parts along the line.

As explained above, according to the present invention, even if an unauthorized member such as piano wire or a steel plate is inserted through the contact surface between the machine frame and the front frame, the protective wall prevents the unauthorized member from coming into contact with the opening lever. Unable to operate opening lever.

Therefore, since it is possible to prevent unauthorized unlocking of the glass frame by unauthorized members, it is possible to open the glass frame and
