Abstract
A continuous paper treating apparatus is provided which includes a tractor for feeding continuous paper and a paper treating unit for treating the paper. The tractor includes a driving belt provided with tractor pins, a tractor lid for covering the driving belt, a support base having a paper support surface for supporting the continuous paper. The tractor also includes a presser member supported by the tractor lid. The presser member is variable in position and posture relative to the tractor lid, and has a pressing surface for pressing the paper. In the tractor, use is made of springs for urging the presser member toward the paper supporting surface, so that the pressing surface presses the continuous paper onto the paper supporting surface.
