Title: Pachinko game machine
Inventor: KANAZAWA HIROSHI
IPC: A63F7/02
Filed: 2001-07-13
Abstract: PROBLEM TO BE SOLVED: To provide a Pachinko game machine, with which a player does not feel suspicion even when error announcing operation in the occurrence of abnormality is executed by erroneous operation, or the like. SOLUTION: When abnormality is detected by a main control panel 60, an error announcement control command signal is continuously transmitted by a specified control unit and each time a sub-control panel receives such an error announcement control command signal, the error announcing operation is controlled and executed by a specified operation unit. Therefore, when the abnormality is recovered, with the transmission stop of the error announcement control command signal, the error announcing operation by a sub-control panel is stopped so that no command can be required for canceling the error announcing operation. Thus, even when the error announcement control command signal is transmitted by a malfunction such as noise, the error announcing operation is immediately stopped and the player does not feel suspicion or misunderstanding on a game.
