Claim:
1. An ink jet printer, comprising: an ink-jet head that discharges an ink on a print object while moving in a main scanning direction relative to the print object; a drive source that generates a driving force by which the ink jet head is moved; an upstream pulley to be rotated by the driving force generated by the drive source; a toothed belt wound around the upstream pulley to transmit the driving force from the upstream pulley toward the ink-jet head; and a downstream pulley on which the toothed belt is wound around to be rotated by the driving force transmitted on the toothed belt, wherein the upstream pulley and the downstream pulley have teeth adapted to mesh with teeth of the tooted belt, and at least one of a group of the teeth of the upstream pulley and the teeth of the toothed belt to be intermeshed and a group of the teeth of the downstream pulley and the teeth of the toothed belt to be intermeshed is a combination of intermeshable spur gear teeth and helical gear teeth.
