Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine in which a front frame is provided on a front surface of a main frame so as to be openable and closable.

[0002]

2. Description of the Related Art In a pachinko machine installed in a game arcade, a game board is arranged in a main frame, and a front frame that can be opened and closed is provided on the front surface of the main frame. In order to prevent fraudulent acts such as goto acts, no one can touch the game board and electronic devices inside the pachinko machine while it is installed in the game hall and the front frame is closed. You can't. When it is necessary for an operator of the game arcade to touch the inside of the pachinko machine, the front frame is opened to perform the work. Therefore, the operator of the amusement arcade monitors the open / closed state of the front frame, as well as preventing the front frame from being opened easily so that the front frame is not opened for the purpose of cheating. When a person was opened, it was necessary to immediately detect this and judge whether or not it was intended for misconduct.

As a method of monitoring the open / closed state of the front frame and detecting that the front frame has been opened, a push button switch is provided between the main frame of the pachinko machine and the front frame, and the push button switch is turned on. Many methods are used to detect the open / closed state of the front frame by turning on / off. Many of the push button switches are provided in the front frame or the main frame at a portion sandwiched between the front frame and the main frame when the front frame is closed. With the front frame closed,
If the pushbutton switch is provided in the front frame, the pushbutton part of the pushbutton switch is pushed down by a predetermined part in the body frame, or if the pushbutton switch is provided in the body frame. For example, the push button portion of the push button switch is pushed by a predetermined portion in the front frame. As a result, the push button switch is always on when the front frame is closed and is always off when the front frame is open, so the open / closed state of the front frame can be detected by the push button switch without using a complicated mechanism. can do.

[0004]

However, in the pachinko machine as described above, when the mounting portion of the front frame is deformed by repeated opening and closing operations of the front frame, the push button portion of the push button switch is depressed. The positional relationship between the push button switch and a predetermined portion of the front frame or the main body frame to be displaced is displaced, so that there is a drawback that the open / closed state of the front frame cannot be detected.

The present invention has been made to solve the above-mentioned problems of the prior art. Even if the positional relationship between the main body frame and the front frame is displaced, the push button switch is used without using a complicated mechanism. An object of the present invention is to provide a pachinko machine capable of detecting the open / closed state of the front frame.

[0006]

In order to achieve the above object, a pachinko machine of the present invention is a body frame on which a game board is arranged, and a front frame which is provided on the front surface of the body frame so as to be openable and closable. A push button switch provided on any one of the body frame and the front frame to detect an open / closed state of the front frame, and the push button switch and the body in a state in which the front frame is closed. An elastic member for pressing the push button switch is provided in a gap between the frames or between the push button switch and the front frame.

In order for the elastic member to press the push button switch stably, a pressing piece is fitted on the elastic member, and the elastic member pushes the push button switch through the pressing piece. Pressing is preferred.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the appearance of a pachinko machine using the present invention. A game board 4 is arranged inside the main body frame 3 of the pachinko machine 2, and a front frame 5 is provided on the front surface of the game board 4 so as to be openable and closable. Below the front frame 5, a supply tray 6 for supplying a hit ball and an operation handle 7 for adjusting the launch strength of a pachinko ball are provided. The player inserts a pachinko ball into the supply plate 6 and operates the operation handle 7 to hit the pachinko ball onto the game board 4. When the front frame 5 is in a closed state, a player or a worker in a game hall uses a glass window 8 formed by mounting a plate-shaped glass on the front frame 5 to play a game area 4a of the game board 4 (see FIG. 2) and the pachinko ball flowing down on the game area 4a can be seen, but it becomes impossible to touch not only the game board 4 but also the internal electronic device (not shown). There is.

FIG. 2 shows the appearance with the front frame 5 opened. A game area 4a surrounded by guide rails 10 is formed on the game board 4, and a symbol display device 11, a starting winning opening 12, a normal winning opening 13, an attacker 14, an out opening 1 are formed.
5 are provided. Further, in the game area 4a, nails, windmills, etc., which are not shown, are also provided. Since these structures are publicly known, description thereof will be omitted. By opening the front frame 5, a worker in the game arcade can adjust these structures.

A push button switch 20 is installed in the body frame 3, and a shock absorber 21 is provided in the front frame 5 in a protruding manner. As will be described later, the shock absorber 21 is composed of a coil spring that is an elastic member and a pressing piece that is externally fitted to the coil spring. Then, when the front frame 5 is closed, the shock absorber 21 provided on the back side of the front frame 5 is
It is arranged between the push button switch 20 and the front frame 5. That is, when the front frame 5 is closed, the shock absorber 21 continues to press the push button switch 20, and therefore the push button switch 20 is always turned on. When the front frame 5 is open, the push button switch 20 is not pressed and is always off. The ON / OFF state of the push button switch is processed inside the pachinko machine 2 as an electric signal, and further, when it is output to the outside, it is processed outside to the operator of the game hall or the worker. This is informed as an open / closed state of the front frame 5.

The position of the front frame 5 in the closed state in the initial state before the mounting portion of the front frame 5 is deformed by repeated opening and closing operations (hereinafter referred to as the reference position).
On the other hand, in the case where the positional relationship between the main body frame 3 and the front frame 5 is displaced, in the state where the front frame 5 is closed,
The relationship between the push button switch 20 and the shock absorber 21 is shown in FIGS. FIG. 3 shows a case where the position of the front frame 5 is closer to the body frame 3 than the reference position. FIG. 4 shows the front frame 5
This is a case where the position of is separated from the reference position with respect to the main body frame 3. Further, when the position of the front surface frame 5 is separated from the reference position with respect to the main body frame 3, the shock absorber 2
FIG. 5 shows the relationship between the main body frame 3, the front frame 5, and the push button switch 20 when the front frame 5 is closed without the provision of 1.

The push button switch 20 includes a push button portion 20.
a, a base case 20b, a switch 20c and a switch receiver 20d built in the base case 20b. The elastic force of the switch 20c tries to maintain non-contact with the switch receiver 20d, and further urges the push button portion 20a to project. When the push button portion 20a is pushed down against the elastic force of the switch 20c, the switch 20c in the base case 20b and the switch receiver 20d come into contact with each other so that electricity is conducted.
The shape and specifications of the push button switch are not limited to the above. Pushbutton switch is turned on when pressed
Anything that can be switched between ON / OFF, circular, square,
The shape and specifications such as the amount of stroke to be pressed may be appropriately used.

In the shock absorber 21, a coil spring 21b is attached to a cylindrical supporting portion 21c, and a cylindrical pressing piece 21a is externally fitted so as to be slidable in the axial direction, that is, in the direction of pressing the push button portion 20a. Is configured. It should be noted that the same effect can be obtained by using only the elastic member such as the coil spring without using the pressing piece as a constituent of the shock absorber, but even if the pressing piece is used, the shape and The specifications may be columnar, prismatic, or the like as appropriate, and the spring material or shape may be appropriately used, such as a metal material, a rubber material, a coil shape, or a plate shape.

When the front frame 5 is closer to the main body frame 3 than the reference position, as shown in FIG.
And the pressing piece 21a is urged by the coil spring 21b in the direction of pressing the push button portion 20a, the push button switch 20 has the same structure as when the front frame 5 is at the reference position. It can be detected that 5 is closed.

When the front frame 5 is separated from the main frame 3 with respect to the reference position, as shown in FIG.
Is extended and the pressing piece 21a is urged by the coil spring 21b in the direction of pressing the push button portion 20a, so that the push button switch 20 is provided with a front surface similar to the case where the front frame 5 is at the reference position. It can be detected that the frame 5 is closed.

When the front frame 5 is displaced from the reference position with respect to the main body frame 3 and the shock absorber 21 is not provided, the front frame 5 is closed as shown in FIG. , The push button portion 20a is not pressed down sufficiently, and therefore the switch 20c and the switch receiver 20d do not come into contact with each other, so that the switch is not turned on. If the position 3 is too close to the reference position, the push button switch 20 may be damaged when the front frame 5 is closed. In order to prevent this, it is necessary to improve the accuracy of each part, which is costly and troublesome.

Further, without providing a shock absorber in the front frame 5,
Even if it is provided between the push button switch 20 and the body frame 3, the same effect can be obtained. FIG. 6 shows the relationship between the push button switch 20 and the shock absorber when the front frame 3 is closed when the shock absorber is provided between the push button switch 20 and the body frame 3. The shock absorber 31 is installed in the main body frame 3 and holds the base case 20b of the push button switch 20. The structure of the shock absorber 31 is the same as that of the shock absorber 21. Even if the front frame 5 is displaced from the reference position with respect to the main body frame 3, the shock absorber 31 expands and contracts in the direction in which the push button switch 20 is pushed and pushes the push button switch 20 in accordance with the displacement. Since the piece 31a biases the push button switch in the protruding direction by the coil spring 31b, the push button switch 20 has the front frame 5 closed as in the case where the front frame 5 is at the reference position. Can be detected.

Further, in the above embodiment, the push button switch is provided in the upper right portion of the body frame, but if the position is such that it is sandwiched between the front frame and the body frame when the front frame is closed, Other locations are acceptable. Furthermore, it may be on the game board.

Further, in the above embodiment, the push button switch is provided in the main body frame, but the same effect can be obtained by providing the push button switch in the front frame. In this case, the positions of the body frame 3 and the front frame 5 in FIGS. 3 to 6 are exchanged, but the positional relationship of the other elements is not changed.

[0020]

As described above, according to the present invention, even if a displacement occurs in the positional relationship between the main body frame and the front frame, the elastic member expands and contracts accordingly to compensate, so that a complicated mechanism is used. The open / closed state of the front frame can be detected without a push button switch.
