Title:
CONTROL DEVICE FOR PACHINKO MACHINE
Document Type and Number:
Japanese Patent JP2759881
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a pachinko machine in which replacement of the pachinko machine can easily and surely be performed, and in which preventive means against illegal actions is provided.
SOLUTION: In a control circuit in a pachinko machine comprising a common ROM 32 in which a usable program in common is stored, a non-common ROM 20 in which a specific program is stored, a CPU 30 to execute the game programs, an oscillation circuit 40 connected to the CPU 30, a RAM 31, and an interruption signal generating circuit 41, the usable ROM 32 in common, the RAM 31, and the CPU 30 are formed in the same integrated circuit. In the case of replacing the pachinko machine with one of another model, therefore, the common integrated circuit is removed from the old model to be inserted to a specified position of the new pachinko machine. The common integrated circuit is formed as an integrated circuit in which plural sorts of circuits exist in mixture, relative relation between its constitution and peripheral circuits, etc. are composed to be difficult to be analyzed by an outsider, thereby generation of illegal action can be restricted.
