Abstract

PURPOSE:To enable a paper to be easily taken out, by separating a paper bail member in conjunction with separation of a pinch-rollr, in a recorder. CONSTITUTION:The paper ball member 10 is turnably supported by a pinch- roller shaft 9, is energized clockwise by a tension spring 13 fitted between a arm form projected part 11 provided as one body with the member 10 and a base 12, and a tip part thereof is pressed against a feeding roller 1. When the pinch roller 3 is set to a separated position indicated by the two-dotted line, the projected part 11 comes to abut against an upper part 12a of the base 12, and the paper bail member 10 is separated from the feeding roller 1 against the spring 13.
