Abstract
PURPOSE: To let the idle feed winding operation of the leading end part of film be automatically accomplished by the built-in electromagnetic release mechanism and motor winding mechanism after automatically resetting a frame number count means by closing the back cover after loading of the film.
CONSTITUTION: When in the camera provided with the power winding mechanism and electromagnetic release mechanism the camera is in a winding uncompleted state at the time when a power source switch SW1 is turned ON, a motor control switch SW5 is OFF and a motor M runs to assume a winding completion state immediately. Then the motor control switch SW5 goes ON upon turning of a blocking lever. Here, when the back cover is opened, film is loaded and the back cover is closed, then a back cover signal switch SW3 goes ON, by which the back cover close signal is emitted, causing a counter 63 to reset and a release magnet Mg 1 to be energized. Release operation is thus accomplished. After travelling of the shutter, the motor control switch SW5 goes OFF and the motor M22 starts running.
