摘要 An apparatus for use with a camera having a lighttight body compartment for retaining a film cassette having a film spool, in which the lighttight body compartment includes a detachable portion. The apparatus includes a sensing member for sensing the camera as it is attached to the apparatus, a spool driving element for engaging an exposed spool end of a cassette film spool, and a pair of pin members which engage and release the detachable portion of the camera body. According to the present invention, a control module automatically controls the action of a drive motor to cause the spool driver to engage the film spool end to wind the film into the cassette. After a predetermined time period has elapsed insuring all of the film is wound, the detachable portion of the camera body is automatically removed by engagement of the pin members and the film cassette is removed from the camera body.
