Abstract:
A camera having a manual film winding apparatus in which a film is wound in association with a rotation of a winding operation device from a wind start position to a wind end position, comprising:an encoder which rotates in association with the movement of the film which is wound by the rotation of said winding operation device and generates a signal each time said winding operation device is rotated by a predetermined angle;a film feed amount detection device which counts output of the encoder to detect the feed amount of the film;a rotation detection device for detecting the rotation of said winding operation device; anda controller which interrupts said encoder by turning said encoder OFF after the lapse of a predetermined time when said winding operation device is stopped during the winding operation, wherein said controller turns said encoder ON when said rotation detection device detects rotation of said winding operation device thereafter, so that the film feed amount detection device continues the counting operation.
