ABSTRACT:
A sheet material transferring apparatus of the type including a transferring roller about which the sheet material is wound, a sheet guiding member and a sheet retainer. The sheet guiding member is formed with a plurality of openings through which pinch rollers are projected inwardly. When it is turned in the one direction by actuating a lever, it assumes an operative position where the pinch rollers and the sheet retainer are brought in pressure contact with the circumferential surface of the sheet guiding member while the spaced relation between the sheet guiding member and the transferring member is maintained whereby the sheet material is transferred along the circumferential surface of the transferring roller. When it is turned in the other direction, it assumes the inoperative position where both the pinch rollers and the sheet retainer are parted away from the circumferential surface of the transferring roller that the sheet material to be transferred is freely inserted into the clearance as defined therebetween so as to allow the sheet material to assume a correct position or orientation. The sheet guiding member is operatively connected to an outer sheet guiding member by meshing engagement of projections and recesses which are formed at the one end of each of them. The sheet retainer may be provided with resilient deforming portions adapted to abut against the one end of the sheet guiding member.
