PROBLEM TO BE SOLVED: To reduce processing loads of a CPU 11. SOLUTION: In a clock signal generating apparatus 51 for generating pulse signals at a variable speed on the basis of a command from a controller, an up/down counter 71 counts up or counts down the count value of the counter at a prescribed speed, and a limit count generation part 72 generates the limit count value of the counter on the basis of the command. A comparison part 73 compares the limit count value with the count value of the counter, and generates the pulse signals when the count value of the counter is larger than the limit count value when the count value is counted up or when the count value of the counter is larger than the limit count value when the count value is counted down. A settlement part 74 clears or presets the count value of the counter at the timing of generating the pulse signals. This invention is applicable to the drive control of the movable accessory of a game machine. COPYRIGHT: (C)2010,JPO&INPIT
