The metal terminals 17a and 17b are in a state of protruding rearward in parallel. In addition, the upper end surfaces of the side plates 12, 12 are in a state where the ground portions 16a, 16b electrically connected to the metal terminals 17a, 17b are exposed. Furthermore, the fitting projections 13 are provided near the upper ends of the left and right sides of the outer surfaces of the side plates 12 and 12 and the lower end of the center.

By fitting the fitting projections 13a, 13a, 13b, respectively, the upper member 6a and the lower member 6b are integrated to sandwich the external terminal plate 4. Then, the integrated cover member 6 has a concave connector shape having only the rear surface opened (that is, in the concave portion 15 in which the top, bottom, left and right are closed, the two metal terminals 17a and 17b protrude to the opening of the rear surface. Shape). Further, the metal terminals 17a and 17b are electrically connected to the proximity sensor 22 via the metal layers 5a and 5b and the ground portions 16a and 16b.

The detection switch 1 configured as described above is
As shown in FIG. 3, an input terminal (a convex connector) 18 of another electronic device is inserted from the rear surface of the integrated cover member 6, and two metal terminals 17 a and 1 located in the concave portion 15.
7b is installed on the back of a game board of a game machine such as a pachinko machine, or is installed inside various winning devices in a state of being electrically connected to the lead wires 21a and 21b of the input terminal 18. used. When the detection switch 1 is installed, the detection switch 1 can be accurately installed at a desired position by using the positioning ribs 7. The detection switch 1 is connected to the metal terminal 17 while the game machine is powered on.
When a certain voltage is applied to the a and 17b, and the game ball passes near the proximity sensor 22 (such as a portion above the proximity sensor 22 of the main body 2), the vicinity of the proximity sensor 22 is accompanied by the passage of the game ball. , The potential difference between the two metal terminals 17a and 17b changes (that is, the voltage changes). For this reason, a game machine such as a pachinko machine in which the detection switch 1 is installed can detect a winning of a game ball by detecting a change in the voltage.

Since the external output terminals (metal layers 5a and 5b) are covered by the cover member 6 (the upper member 6a and the lower member 6b), the external output terminals are formed. It is possible to effectively prevent an illegal act of attaching an incorrect substrate to the substrates 5a and 5b. Further, by utilizing the connector shape of the cover member 6, it is possible to very easily connect to a connector (such as the input terminal 18) which is an input terminal of another electronic device. Furthermore, malfunction does not occur due to static electricity from other electronic devices. In addition, since the detection switch 1 has a concave connector shape in which the cover member 6 has an opening only at the rear surface, the detection switch 1 is highly versatile and can be connected to many other electronic devices having a convex connector.

The shape is not particularly limited as long as it covers the external output terminal.

Further, the cover member is not limited to a member detachably attached to the external output terminal, but may be a member fixed to the external output terminal such as a ground portion soldered to a metal layer of the external output terminal. When the cover member is formed by soldering the ground portion to the metal layer of the external output terminal, the contact state between the detector and the metal terminal of the cover member is good even when the gaming machine is subjected to vibration. There is a merit that it is kept. In addition, the cover member is not limited to one having a concave connector shape, and may have a convex connector shape.

The detector incorporated in the main body is not limited to a non-contact type sensor using a permanent magnet, but may be a non-contact type sensor using an optical sensor. The shape and structure are not particularly limited as long as they can be converted. When using a proximity sensor,
The proximity sensor may be one in which the surrounding magnetic flux density decreases as the game ball passes, and the potential difference between the external output terminals decreases due to the decrease in the magnetic flux density, or the surrounding magnetic flux density decreases as the game ball passes. And the potential difference between the external output terminals may increase due to the change in the magnetic flux density.

Further, in order to indicate the position of the built-in detector, the detection switch can be printed, engraved, or the like on a portion of the main body above the detector. When such a configuration is adopted, the detection switch can detect a game ball with high sensitivity simply by installing the portion such as printing, engraving, and the like to the game ball to be detected,
There is an advantage.
