<p>There is provided a low price camera having a simple structure in which a winding operation and a rewinding operation can be performed by one knob and an APS film capable of displaying a film used state is used. When a reverse rotation preventing lever 4 is disposed at a first position, a reverse rotation preventing pawl 4a is meshed with a winding knob 2 so as to make it possible to rotate only counterclockwise, thereby rotating a winding shaft 3 interlocking therewith so as to wind a film. At a second position in which a rewinding button 5 is pushed so as to become an operating state and the reverse rotation preventing lever 4 is swung, the reverse rotation preventing pawl 4a is meshed with the winding knob 2 so as to make it possible to rotate only clockwise, thereby interrupting an interlock with the winding shaft 3 and rewinding the film by a rotation of the winding knob 2. In order to return the rewinding button 5 to a non-operating state, an operating lever 11 is swung, thereby releasing an engagement between an engaging portion 12a provided on a shaft of the operating lever and an elastically engaging arm 5d. Further, a transmitting wheel train interlocking with a swing motion of the operating lever for locking a cover is provided, a clutch lever is frictionally connected in this wheel train, a clutch is let in when taking out a film cartridge and so a drive gear and a rotating gear are rotated together, and the clutch is disengaged when inserting the film cartridge and so only the drive gear is rotated. <IMAGE></p> |
