A drive shaft is disposed in each of the slide blocks for driving the track rotating body and the drive roller. A roller shaft supports thereon a pair of pinch rollers for contacting the drive rollers, respectively, and is movable away from the slide blocks, the pinch rollers being held by the paper holder members for slidable movement along the roller shaft in response to movement of the slide blocks.
