发明名称 Camera film feed device and film feed method
摘要 A camera film feed device is provided for enabling freely loadable placement of a film magazine which has a takeup shaft on which a film is wound and which has a film leader protruding from a film feeding opening. The camera film feed device includes a magazine chamber into which the film magazine is loaded, a fork which joins in mating fashion with the takeup shaft of the film magazine loaded into the magazine chamber, a takeup spool which is positioned on a side of a photographing aperture opposite the magazine chamber and which takes up the film, a sprocket which is positioned between the magazine chamber and the takeup spool, and a control circuit which controls the operations of the fork, takeup spool and sprocket. The control circuit starts an operation by the fork to rewind the film into the film magazine when the film magazine is loaded into the magazine chamber, stops the rewind operation when the film is rewound to a prescribed position, and then starts an operation by the sprocket to feed the film toward the takeup spool.
