PROBLEM TO BE SOLVED: To provide a stepping motor driving device having a further simplified constitution. SOLUTION: A stepping motor driving device is provided with a control means 21 which outputs a pulse width modulated signal, by successively reading out and outputting a desired output pattern stored in the device based on the driving amount of a stepping motor 3. Therefore, the constitution of the driving device can be simplified, because another driving circuit which is used in the conventional example for generating the pulse width modulated signal when the driving amount of the motor 3 is transmitted to the driving circuit from a control means becomes unnecessary. |
