Abstract:
A pressure releasing lever is operated to switch the position of a locking member between a pressure exertion position and a pressure release position. In the pressure exertion position a pressure exerting roller exerts pressure against another roller via a pressure exerting lever and in the pressure release position the pressure exerting roller separates from the roller. An elastic member pulls the locking member and a second end of the pressure exerting lever in a locking direction. A core end of the pressure exerting roller is rotatably supported by a shaft bearing. The pressure exerting lever engages with the shaft bearing.
