PROBLEM TO BE SOLVED: To discriminate short circuit of a contact and removal of a connection part.SOLUTION: A setup key switch 72 includes: an off state where a contact 1 and a COM become a non-connected state and a contact 2 and the COM becomes a connected state; an on state where the contact 1 and the COM become the connected state and the contact 2 and the contact COM become the non-connected state; and an intermediate state where the contact 1, the contact 2, and the COM become non-connected state. A key setup switch signal to inputs in the contact 1 and the contact 2 is input in a main control board 50, and a setup key switch abnormal signal detection signal to inputs of the contact 1, the contact 2, and the COM is input in the main control board 50. The game machine is so configured that, when a circuit connected to the contact 1 or to the contact 2 and a circuit connected to the COM are short-circuited, and when the connection between the setup key switch 72 and the main control board 50 is removed, the logic of the setup key switch abnormal detection signal is reversed. 【課題】接点のショートや接続部の外れを判別する【解決手段】設定キースイッチ７２は、接点１とＣＯＭとが非接続状態となり、かつ接点２とＣＯＭとが接続状態となるオフ状態と、接点１とＣＯＭとが接続状態となり、かつ接点２と接点ＣＯＭとが非接続状態となるオン状態と、接点１及び接点２とＣＯＭとが非接続状態となる中間状態とを有する。接点１及び接点２の入力に対する設定キースイッチ信号をメイン制御基板５０に入力し、接点１、接点２及びＣＯＭの入力に対する設定キースイッチ異常検出信号をメイン制御基板５０に入力する。接点１又は接点２に接続する回路と、ＣＯＭに接続する回路とをショートさせたとき、及び設定キースイッチ７２とメイン制御基板５０との接続を外したときは、設定キースイッチ異常検出信号の論理が反転するようにする。【選択図】図２
