Abstract

In a camera, a film presence sensing switch is located to detect the beginning of a full width main section of a filmstrip after a reduced width leading section of the filmstrip is wound at least partly onto a take-up spool. When a sufficient time has elapsed during the film winding operation for the reduced width section of the filmstrip to be wound onto the take-up spool, a motor drive for rotating the spool in a winding direction is de-energized should the switch fail to detect the beginning of the full width section of the filmstrip. Alternatively, the motor drive is allowed to remain energized to continue the film winding operation should the switch detect the beginning of the full width section.
