SOLUTION: The substrate unit for the game machine comprises: a substrate having a semiconductor circuit device for controlling operation of the game machine; a connector arranged on the substrate to connect the semiconductor circuit device and an external circuit electrically; a substrate cover which is provided with an opening part for exposing the connector to the outside and which surrounds the substrate; and a ring body projecting from the periphery of the bottom part of the connector and contacting the substrate. The ring body can be separated from the connector. Moreover, it is possible that the ring body is provided with a projecting part and that the substrate cover has a recessed part which the projecting part is fitted into. COPYRIGHT: (C)2006,JPO&NCIPI
