ABSTRACT:
A mounting mechanism of a camera having a film take-up spool is provided for mounting a film pressing roller on a camera body. The mounting mechanism includes a back cover, a roller supporting arm, an elastic member and a pressing device. The back cover is rotatably supported by the camera body. One end of the roller supporting arm is rotatably mounted to the camera body, and another end of the roller supporting arm is provided with the film pressing roller. The elastic member is provided on the camera body and engages with the roller supporting arm to hold the film pressing roller at a predetermined position spaced from the film take-up spool when the back cover is opened. The pressing device is provided on the back cover for pressing the elastic member toward the film take-up spool when the back cover is closed, so that the roller supporting arm is biased toward the film take-up spool by the biasing force of the elastic member to thereby press the film pressing roller toward the film take-up spool.
