ABSTRACT:
A recording medium transport device has: a pair of transport roller units which nip and transport a recording medium and which are disposed at an upstream side and a downstream side of a recording area respectively, the transport roller unit in the upstream side including a drive shaft and an upstream side transmission gear attached to the drive shaft, the transport roller unit in the downstream side including a drive shaft and a downstream side transmission gear attached to the drive shaft; an output shaft; and a drive pinion gear attached to the output shaft and engaging with both the transmission gears. Each of the upstream side transmission gear, downstream side transmission gear and the drive pinion gear is a gear in which two spur gears are integrally formed while phases of the two spur gears are shifted from each other by a half pitch.
