PROBLEM TO BE SOLVED: To provide a Pachinko machine that enables easy detection of a Pachinko machine having a history of fraudulent opening of a main control board case. SOLUTION: When a main control board case 57 is opened, the pushing member SW1a of a switch SW1 attached to the right side surface 55c of a case body 55 is protruded rightward through the right side surface 55c of the case body 55; the switch SW1 is turned on; and the history of the opening of the main control board case is stored in a storage unit of an opening detection circuit. When the history of the opening of the main control board case 57 is stored in the storage unit, the Pachinko machine providing notification of an error is detected because a check sum signal outputted to a performance device together with a performance control signal by a CPU for main control is rewritten to provide the notification of the error. This enables the easy detection of the Pachinko machine subjected to the fraudulent act of the opening of the main control board case 57. COPYRIGHT: (C)2012,JPO&INPIT |
