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.
Claims11
A continuous paper treating apparatus comprising:
- a tractor including a rotatable driving member provided with a plurality of tractor pins, the tractor also including a tractor lid for covering the driving member;
- and
- treating means for treating continuous paper transferred along a predetermined path by the tractor;
- wherein the tractor further includes a support member having a paper support surface for supporting the continuous paper, the tractor further including a presser member supported by the tractor lid, the presser member being variable in position and posture relative to the tractor lid, the presser member having a flat pressing surface for slidable contact with the continuous paper, the tractor further including urging means for urging the presser member toward the paper supporting surface so as to cause the pressing surface to press the continuous paper onto the paper supporting surface;
- and wherein further
- the tractor lid is movable to be selectively brought into facing relation to the paper supporting surface, the tractor lid being urged toward the paper supporting surface with a first urging force, the presser member being urged toward the paper supporting surface with a second urging force which is greater than the first urging force.
A tractor for transferring continuous paper comprising:
- a rotatable driving member provided with a plurality of tractor pins;
- a tractor lid for covering the driving member;
- a support member having a paper support surface for supporting the continuous paper;
- a presser member supported by the tractor lid;
- the presser member being variable in position and posture relative to the tractor lid, the presser member having a flat pressing surface for slidable contact with the continuous paper;
- and
- urging means for urging the presser member toward the paper supporting surface so as to cause the pressing surface to press the continuous paper onto the paper supporting surface, wherein the tractor lid is movable to be selectively brought into facing relation to the paper supporting surface, the tractor lid being urged toward the paper supporting surface with a first urging force, and the presser member being urged toward the paper supporting surface with a second urging force which is greater than the first urging force.
