ABSTRACT:
A step motor driving device comprises a single control circuit and a single voltage generating circuit for controlling plural step motors, each step motor being connected to a drive circuit. The control circuit outputs a control signal to the voltage generating circuit so that it selectively supplies high voltage and/or low voltage to the step motors. Therefore, the driving device of the present invention can control more than two step motors either jointly or individually by means of a simple circuit structure.
