  In a slot machine equipped with the above-described medal sorting device, it has been known that an illegal act of playing a game without using a medal by inserting a celluloid plate or the like from a medal slot and causing the optical sensor to malfunction. It has been. Although countermeasures against the conventional fraud have been advanced, recently, new fraud using the instrument 23 (see FIG. 5) in which the LEDs 21 and 22 are attached to the tip of the transparent celluloid plate 20 has become a problem. It has become.

  In this new fraudulent act, when the sensors 10 and 11 are light transmission sensors, the instrument 23 with the LEDs 21 and 22 lit is inserted from the medal slot, and the sensors 10 and 11 are light reflection sensors. In some cases, an instrument 23 with the LEDs 21 and 22 turned off is inserted from the medal slot, and the LED 21 is operated at a position corresponding to the sensors 10 and 11 by operating the operation unit at hand with the instrument 23 inserted. , 22 are sequentially flashed at a predetermined timing, and the same state as that in which the medal passes in front of the optical sensors 10, 11 is created. Since the LEDs 21 and 22 are attached to the transparent celluloid plate 20, even if this instrument 23 is inserted from the medal slot for a long time, the optical sensors 10 and 11 cannot detect the abnormality, and this kind of fraud The action could not be prevented.

  The present invention has been made for the purpose of preventing a new fraud that is difficult to detect abnormalities in the conventional medal sorting device as described above. The issue is to provide at low cost.

  In order to achieve the above object, the medal sorting device according to the first aspect of the present invention is provided with two sensors along the moving direction of the medal in the medal passage following the medal insertion slot. In the medal sorting device of the slot machine configured to accept the medal inserted from the medal slot based on the information from these two sensors, each of the two sensors includes a light emitting unit, a light receiving unit, Are individually disposed on both sides of the medal path, and are light transmission type sensors that detect the medal when the light from the light emitting unit is blocked by the medal and the light receiving unit does not receive light. The light emitting unit and the light receiving unit are arranged opposite to each other across the medal passage.

In the medal sorting device according to the second aspect of the present invention, two sensors for detecting the passage of medals are provided in the medal passage following the medal slot, and information from these two sensors is provided. In the medal sorting device of the slot machine configured to accept the medal inserted from the medal slot, both of the two sensors have the light emitting part and the light receiving part located on the same side of the medal path, A light-reflective sensor that detects a medal when the light-receiving unit receives light from the light-emitting unit reflected by the medal, and the two sensors are arranged on opposite sides of the medal passage. And

  Two light transmissive sensors in which each light emitting part and light receiving part are arranged at positions opposite to each other across the medal path, or two light reflection type sensors arranged on the opposite sides across the medal path In order to make it malfunction, it is necessary to use the instrument which attached LED to both surfaces of support bodies, such as a celluloid board. In this case, the maximum width of the instrument is a value obtained by adding the thickness of two LEDs to the thickness of the support, and is larger than the width of the medal passage. For this reason, it is impossible to insert the instrument into the medal passage.

  Therefore, the slot machine provided with the medal sorting device according to the present invention can completely prevent an illegal act using an instrument having an LED attached to the tip of the transparent celluloid plate in both claims 1 and 2. In addition, this medal sorting device can cope with this by simply replacing one of the two optical sensors in the existing medal sorting device or changing the positions of the light emitting and receiving portions of the sensor, thereby increasing the number of parts. And can be provided at low cost without significantly changing the configuration.

  FIG. 1 is a diagram in which a part of a medal sorting device to which the present invention is applied is omitted. In the medal sorting device 1, a medal passage 5 is formed between the main plate 2 and a sub plate 3 provided at an appropriate interval on the front side thereof, following the medal slot 4. The medal passage 5 is formed with a width slightly larger than the width of the medal. The medal guide rail at the bottom of the medal passage 5 includes a first rail 6 in the front half and a second rail 7 in the rear half, and the first rail 6 is provided integrally with the main plate 2, and the second rail. 7 is provided to be movable in the front-rear direction by an operating coil (not shown).

  In normal times, the second rail 7 is on the extension of the first rail 6, and the medal M is guided by the rails 6, 7 and moves in the medal passage 5. Further, during the game, during the game settlement, at the time of stopping, etc., the second rail 7 moves backward by energizing and outputting the operating coil, and the medal M inserted from the medal insertion slot 4 comes off from the second rail 7. Fall and return to the medal tray.

  Above the first rail 6, a guide spacer 8 that restricts passage of medals larger than the regular medals M is provided. When the medal M is jammed between the first rail 6 and the guide spacer 8, the medal M jammed in the cancel plate 9 is pushed out by operating the manual return button, and the medal is detached from the first rail 6. It comes to fall. In addition, a medal smaller than a regular medal falls backward due to its own weight and falls off the first rail 6. The medals that fall off the first rail 6 are returned to the medal tray.

  Above the second rail 25, two sensors 10 and 11 for detecting the passage of the medal M are provided side by side along the moving direction of the medal. The detection signals of these sensors 10 and 11 are transmitted to the control unit 12 of the slot machine body. The control unit 12 determines whether or not the medal M is moving normally through the medal path 5 from the order in which the sensors 10 and 11 detect the object and the time difference between the detections. If it is determined to be normal, the medal is accepted and medal credit is added. If it is determined to be abnormal, it is output to the error notification unit 13 to notify that it is abnormal. As the sensors 10 and 11, there are embodiments of the following Examples 1 and 2, and any of them may be applied.

  FIG. 2 is a view taken in the direction of arrow A in the first embodiment. Both sensors 10 (11) are both light-transmitting sensors, and the light emitting unit 10a (11a) and the light receiving unit 10b (11b) are individually arranged on both sides of the medal path 5, and the light emitting unit 10a ( When the object such as the medal M blocks the light from 11a) and the light receiving unit 10b (11b) does not receive the light, the object is detected. In the sensors 10, 11, the light emitting portions and the light receiving portions are arranged opposite to each other across the medal passage. In the case of the first embodiment, the upstream sensor 10 near the medal slot 4 has a light emitting unit 10a on the right side of the medal passage 5 and a light receiving unit 10b on the left side based on the moving direction of the medal, and a sensor 11 on the downstream side. The light emitting unit 11a is arranged on the left side of the medal path, and the light receiving unit 11b is arranged on the right side. You may arrange | position the light emission part and light-receiving part of both sensors 10 and 11 reversely on both sides of a medal path.

  As shown in FIG. 4, in order to cause the upstream and downstream light transmission sensors 10 and 11 in which the respective light emitting units and light receiving units are disposed opposite to each other across the medal passage as described above, as shown in FIG. It is necessary to use an instrument 23 in which two LEDs 21 and 22 are attached to both surfaces of the transparent celluloid plate 20. However, since the width B of the medal passage 5 is slightly larger than the width of the medal, when the appliance 23 is made as described above, the maximum width C of the appliance 23 is wider than the width B of the medal passage 5. turn into. For this reason, it is impossible to insert the instrument 23 into the medal passage 5, and an illegal act using this type of instrument is not established.

  FIG. 3 is a view as viewed from the direction of the arrow A in the second embodiment. Both sensors 10 (11) are light-reflective sensors, and the light emitting part 10a (11a) and the light receiving part 10b (11b) are both located on the same side of the medal path 5, and are attached to an object such as the medal M. When the light receiving unit 10b (11b) receives the reflected light from the light emitting unit 10a (11a), the object is detected. Both sensors 10, 11 are arranged on opposite sides of the medal passage. In the second embodiment, the upstream sensor 10 near the medal slot 4 is arranged on the right side of the medal passage 5 with respect to the medal movement direction, and the downstream sensor 11 is arranged on the left side of the medal passage 5. Yes. You may arrange | position both the sensors 10 and 11 in the right-and-left reverse.

  In this way, even when the upstream and downstream light reflecting sensors 10 and 11 arranged on the opposite sides of the medal passage 5 are erroneously operated, as shown in FIG. It is necessary to use an instrument 23 having two LEDs 21 and 22 attached on both sides. As described in the first embodiment, since it is impossible to insert the instrument 23 into the medal passage 5, an illegal act using this type of instrument is not established.

  The medal sorting device of the present invention can be applied to other gaming machines and vending machines that use medals, coins, and the like in addition to slot machines.
