ABSTRACT:
A belt driving apparatus is disclosed, that uses feedback signals for executing feedback control of a motor that drives the rotation of a belt. The belt driving apparatus includes a first sensor for detecting an index of a scale formed along a peripheral direction of the belt, a second sensor for detecting a detection target cooperatively moving with the rotation of the belt, and a sensor switching part for selectively switching the feedback signals used for executing the feedback control of the motor. The feedback signals include first signals output from the first sensor and second signals output from the second sensor. The sensor switching part selects the first or second signals accordingly.
