Abstract
PURPOSE:To control operation efficiently in a camera wherein a film is all wound first and then rewound in a cartridge on every shot, by detecting film unloaded, back-cover opened, and preliminary winding completion with one switch. CONSTITUTION:A mode switch SWc turns on when the back cover of a camera is closed after a film is loaded. An H-level signal is inputted to a gate AND3 and an NAND4. At this point of time, a counter switch SWs is also on, and the gate output of the AND3 is therefore held at a level H; and consequently, a timer TM1 generates a 2.5 second H-level output to hold the output of the gate NAND4 at a level L, and then a relay RL2 is energized to reverse a motor, performing preliminary winding operation. Once the preliminary winding operation ends, a tension detecting mechanism for a film turns off the mode switch SWc to stop the motor, and also to reset a photographing inhibition signal inputted to a gate AND2.
