PROBLEM TO BE SOLVED: To reduce the occupation capacity of the phase control data area of a stepping motor in a memory at a control section. SOLUTION: A heap area 8F, where a data storage area 8G for several number of steps required for driving a stepping motor 3 every time is formed selectively, is arranged in the memory 4 at a control section 1 and the data storage area 8G for several number of steps required for driving the stepping motor 3 every time is formed in the heap area 8F. The data storage area 8G is opened upon ending the drive of the stepping motor 3, thus reducing the occupation capacity of the data storage area 8G. |
