Abstract

PURPOSE: To automatically stop film feed operation by providing the circuits and change-over means for assigning film winding and rewinding and stopping the current supply to a drive motor upon completion of film feeding.
CONSTITUTION: When a release switch 14 is turned ON, the release operation of mirror up→exposure→mirror down is accomplished. When the mirror descends, a mirror switch 18 is changed over to the 1st contact side and at the same time the 1st switch 16 is changed over from the 2nd contact to the 1st contact. As a result of this, a timer circuit 26 is triggered to supply the timer signal to the 1st input end of the 1st AND gate 28 and when the 1st switch 16 is changed over to the 1st contact, a transistor Q4 is turned ON and a relay 34 is again energized to flow the current in the A direction, causing a motor 38 to run in the specified direction. This running is continued until the film winding for the one shot ends. When it ends, the selection state of the 1st switch 16 resets to the 2nd contact side and the feed operation stops. In this way, the film feed operation may be automatically stopped.
