摘要：
A camera comprising a film winding thumbwheel supported for rotation in a film winding direction and an opposite film unwinding direction, an anti-backup wheel supported for rotation in engagement with the thumbwheel, and an arresting device for preventing rotation of the anti-backup wheel in order to prevent rotation of the thumbwheel in the film unwinding direction, is characterized in that the arresting device is a stop engageable with the anti-backup wheel to prevent rotation of the anti-backup wheel and disengageable from the anti-backup wheel to permit rotation of the anti-backup wheel, and the anti-backup wheel is supported to be moved out of position spaced from the stop and into engagement with the stop, without becoming disengaged from the thumbwheel, when the thumbwheel is attempted to be rotated in the film unwinding direction.
