Camera with spool positioning mechanism |
摘要 |
A camera includes a film rewind mechanism that allows manual rewinding of a film spool to a given position. The mechanism includes a one-way clutch that allows the rewind knob to drive the film spool only in a rewind direction. The clutch mechanism has a single arm for transfer of motion between the rewind knob and a spool driver. Use of the single arm clutch allows the rewind knob to be connected with the spool only in a single unique position or phase relation so that the operator can move the rewind knob to an indicated position of the camera body which corresponds with a similarly indicated position of the spool on the film cassette.
