Abstract
A printer has a tractor unit with a simple configuration that can prevent the feed holes in continuous paper from disengaging the engagement pins of the tractor unit during conveyance. The tractor unit of the printer has a pair of tractors that hold the continuous paper with tractor pins (engagement pins) engaged in sprocket holes (feed holes), a drive shaft and a support shaft that support the pair of tractors, and a frame that supports the drive shaft and support shaft. The first tractor is fixed in position to the support shaft after engaging and holding one side of the continuous paper, but the support shaft is supported on the frame movably widthwise to the printer. If the continuous paper becomes skewed, the first tractor moves with the support shaft widthwise to the printer following the skew, and the sprocket holes therefore do not disengage the tractor pins.
