PURPOSE: To accomplish preparation of slips and others quickly with a simple control based on information obtained through a centralized control system for collectively handling the management of pachinko machines, operation control, inventory control of prizes.

CONSTITUTION: According to the output a of means for detecting balls each time they are struck with a pachinko machine and the output S of a means of detecting replenished balls, the number of struck balls and replenished balls are counted with a counting means CT. A memory M1 memorizes the number of struck balls and replenished balls for each game machine counted by the means. A management control panel OP is equipped with a means for setting the number of balls for suspension of operation, a numerical information input means for inputting the machine number, and a printing command means. A printing means JRP records printed information. An arithmetic control means CAC computes the difference between the number of struck balls and replenished balls in sequence based on the output of the counting means to be memorized with a memory while feeding information memorized to the printing means for memorizing thereof in printing. A suspension control means HC suspends the striking of balls the moment the difference by machine number exceeds the set number of balls for suspension.
