SHEET GUIDING MECHANISM, IMAGE FORMING APPARATUS

摘要

A sheet guiding mechanism includes a pair of first rotators and a pair of second rotators provided in a conveying path for a sheet material, a first sheet guide portion, a second sheet guide portion, a shaft member, and a plurality of guide rollers. The first sheet guide portion and the second sheet guide portion form guide surfaces for the sheet material on both sides of the conveying path. Both end portions of the shaft member extending along a width direction are supported by the second sheet guide portion. The guide rollers are in contact with the sheet material conveyed in the conveying path, and rotate to follow the sheet material. The shaft member is bent by a pressure applied from the sheet material to the guide rollers when a tension is applied to the sheet material between the pair of first rotators and the pair of second rotators.

主权项

1. A sheet guiding mechanism comprising:
a conveying path in which a sheet material is conveyed; a pair of first rotators provided in the conveying path, and configured to convey the sheet material; a pair of second rotators provided on a downstream side in a conveying direction of the sheet material relative to the pair of first rotators in the conveying path, and configured to convey the sheet material conveyed by the pair of first rotators; a first sheet guide portion forming a guide surface configured to guide the sheet material, on a first side of the conveying path; a second sheet guide portion forming a guide surface configured to guide the sheet material, on a second side of the conveying path; a shaft member extending along a width direction orthogonal to the conveying direction of the sheet material, and having both end portions supported by the second sheet guide portion; and a plurality of guide rollers rotatably supported by the shaft member and arranged along the width direction, the guide rollers being in contact with the sheet material conveyed in the conveying path, and rotating so as to follow the sheet material, wherein the shaft member has flexibility such that the shaft member is bent by a pressure applied from the sheet material to the plurality of guide rollers when a tension is applied to the sheet material between the pair of first rotators and the pair of second rotators.
