ABSTRACT:
A camera comprising a slide manually movable in forward and reverse directions, and a spool drive device connectable with a film spool for rotation in a winding direction to similarly rotate the film spool, is characterized in that the slide and the spool drive device are engaged with each other at a first location, to rotate the spool drive device in the winding direction, and simultaneously slip in contact with each other at an opposite location, to not interfere with rotation of the spool drive device in the winding direction, when the slide is moved in the forward direction, and are engaged with each other at the opposite location, to rotate the spool drive device in the winding direction, and simultaneously slip in contact with each other at the first location, to not interfere with rotation of the spool drive device in the winding direction, when the slide is moved in the reverse direction, whereby a two-way drive coupling is created between the slide and the spool drive device.
