ABSTRACT:
A stepping motor driving device of this invention includes: a first ROM for outputting an intermittent drive signal, a second ROM for outputting a continuous drive signal, a bus selector into which these signals are input, the bus selector also selectively outputting either one of these signals in response to a selection signal, and a driver for driving the stepping motor intermittently or continuously on the basis of the signal selected by the bus selector. In consequence, the stepping motor can be driven intermittently or continuously by a single driver.
