Abstract

PURPOSE:To wind a film easily without requiring the operation for mode switching, by rotating a driving source in directions opposite to each other for winding and rewinding respectively and by switching automatically the connection of an advancing shaft and a rewinding shaft to the driving source by this rotation in directions opposite to each other. CONSTITUTION:When a motor provided in an winding spool 2 is rotated normally or reversely, a switching gear 11 is switched automatically from gearing for winding to gearing for rewinding or inversely in accordance with this switching. That is, since a friction spring 12' is provided between a sprocket shaft gear 3 and a switching arm 12 which supports the switching gear 11 axially, the switching arm 12 is so switched automatically that the switching gear 11 gears into an accelerating gear 13 for counterclockwise rotation of the sprocket shaft gear 3 for winding and gears into an equal-speed gear 16 for clockwise rotation of the sprocket shaft gear 3 for rewinding.
