PROBLEM TO BE SOLVED: To achieve a proper detection regardless of an attachment position of a sensor.SOLUTION: A vibration sensor 400 is supported directly by a stay 410 and indirectly by a board base 460. The board base 460 is supported at a portion of one end thereof in a cantilever manner by a game plate 8b. Therefore, the board base 460's other end part which is not supported or fixed supports the vibration sensor 400 as if in the air. Since each member is disposed and supported in such a manner, a vibration generated following an impact received by a Pachinko machine 1 can be amplified by the unfixed portion. Accordingly, even a fine vibration difficult to detect can be detected by the vibration sensor 400 with high sensitivity.SELECTED DRAWING: Figure 7 |
