DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show a first embodiment of the present invention. FIG. 1 shows an appearance of an open / close detection device, and FIG. 2 shows a mounting structure of a detector 21. FIG.
[0007]
The open / close detection device will be described with reference to FIG. The gaming machine frame 1 is attached to a frame-shaped outer frame 2 fixed to an island of a pachinko store so that a frame-shaped front frame 3 can be opened by a frame hinge 4 so as to be able to be opened one side. On the front side of the front frame 3, the frame support 5 is fixed to the peripheral edge surrounding the central opening of the front frame 3. A panel frame 6 and an upper plate device 8 are attached to the frame support 5 by a decorative hinge (not shown) so as to be able to be opened on the front side. The open / close centers of the front frame 3, the panel frame 6 and the upper plate device 8 are on the same side.
[0008]
A panel 7 made of a synthetic resin or glass having a light transmission property such as colorless is fitted in the panel frame 6, and a front decoration (not shown) surrounds the panel frame 6 and the lower dish device 10 on the front side of the front frame 3. And the lower dish device 10 is fixed lower than the upper dish device 8. A handle grip 11 for driving the ball launcher is arranged on the right side of the lower dish device 10. In a state where the panel frame 6 and the upper plate device 8 are opened, the front frame 3 stores an unillustrated game board having a guide rail, a winning opening device, a symbol display device, a windmill, an out port, a display, and the like.
[0009]
In this embodiment, the panel frame 6 constitutes an opening / closing body, the panel frame 6 includes a pressing portion 20 on the free end side, the front frame 3 constitutes a mating member, and the front frame 3 has a frame on the free end side. A contact type detector 21 such as a microswitch is elastically supported by a leaf spring 23 via a support 5. As shown in FIG. 2, the detector 21 is a contact type like a microswitch, has a button 22, and the button 22 faces the front side, that is, the panel frame 6 side. The detector 21 is fixed to a free end portion of a leaf spring 23 that is supported by one side on the frame support 5 and is inserted into a through hole 24 formed in the frame support 5. The leaf spring 23 has a spring force that restores in a direction in which the leaf spring 23 comes into contact with the peripheral wall 25 protruding to the back side from the periphery of the through hole 24 of the frame support 5.
[0010]
When the panel frame 6 is closed in a state where electricity is supplied to the detector 21 through an electric wire (not shown), the pressing unit 20 pushes the button 22 of the detector 21, and the detector 21 is connected to the panel frame 6. An off signal corresponding to the detection of closing is output to a control device (not shown). Even after the button 22 is pushed by the pressing portion 20 and the detector 21 outputs an off signal, the leaf spring 23 is moved from the position indicated by the solid line in FIG. By bending to the indicated position side, bottom-out due to excessive pressing of the button 22 is prevented. In this state, the panel frame 6 is opened, and the leaf spring 23 is restored from the phantom line position shown in FIG. 2 to the solid line position and comes into contact with the peripheral wall 25, and then the pressing portion 20 is retracted from the button 22 of the detector 21. When the button 22 is restored to the front side by the spring force built in the detector 21, an ON signal corresponding to the detection of the opening of the panel frame 6 by the detector 21 is output to the control device.
[0011]
On the other hand, when the panel frame 6 is closed vigorously, the leaf spring 23 is bent from the solid line indicated position in FIG. 2 to the virtual line indicated position side to absorb the impact of the panel frame 6 closed vigorously. The entire impact force of the closed panel frame 6 is not input to the detector 21. When the leaf spring 23 returns from the phantom line indicated position in FIG. 2 to the solid line indicated position, the leaf spring 23 is received by the peripheral wall 25 and does not move further forward. Can be prevented from rising to the front side of the stop position, and the inconvenience that the detector 21 is damaged can be solved. By preventing the detector 21 from being lifted to the front side, the position of the button 22 to the front side becomes accurate, and the opening / closing detection of the panel frame 6 by the detector 21 becomes accurate.
[0012]
FIG. 3 shows a second embodiment of the present invention. FIG. 3A shows a case where a circuit board 26 in which the detector 21 is mounted on the frame support 5 is fixed to both supports by a vibration isolating rubber 27 so that the detector 21 can be moved in parallel with the frame support 5. is there.
