FILM REWIND JUDGING MECHANISM AND FILM REWINDING METHOD

摘要

PROBLEM TO BE SOLVED: To reliably judge a rewind of a film to a film spool. ;SOLUTION: When a film 20 is rewound around a film spool 17 housed in a film cartridge 10, a measuring sensor arranged in an exposing gate of a camera detects the tip of the film 20. When the tip of the film 20 is detected, a data disk sensor 18 tracks rotating speed of the film spool 17 from that time. Time when tracking of prescribed rotating speed of the film spool 17 finishes is judged, and prescribed parking operation is performed on the film spool 17.;COPYRIGHT: (C)1996,JPO
