PROBLEM TO BE SOLVED: To secure communication data between a main control board and a put-out control board, to reduce a processing load of the main control board, to grasp a shooting handle operation condition of a player, to improve backup ability, and to reduce an area of the main control board for lowering a cost. SOLUTION: In a configuration as an one-way communication circuit, communication between the main control board 30 and the put-out control board 31 is carried out through handshake communication, while transmission to control boards such as a pattern control board 32b, a shooting control board 33, a lamp control board 34, and a sound control board 35 excepting the put-out control board is allowed only from the main control board 30. Data reliability can be secured as the communication between the main control board 30 and the put-out control board 31 is carried out through the handshake communication, and problems of fraudulent operations can be eliminated by an equipped security function. Batteries of RAM 80 and 81 in the main control board 30 and the put-out control board 31 are backed up, and prize ball put-out management is carried out only by the put-out control board 31. After detection of a break, detection of a prize ball put-out switch 31a is not carried out. COPYRIGHT: (C)2003,JPO
