Claims

[Claims for Utility Model Registration] (1) A spool having a locking means for a film tongue piece in a slit formed through the winding shaft so that the film insertion opening of the slit directly faces the film guide chute. a first sensor for detecting the slit penetrating end of the film tongue inserted into the slit, and a second sensor for detecting the edge of the film provided with the film tongue, located near the holder. A film insertion confirmation device for a spool, characterized in that the film is inserted into a spool. (2) The first sensor and the second sensor are composed of a light-emitting element and a light-receiving element that face each other across the film passing surface, and when the light from the light-emitting element is blocked by the film and there is no output from the light-receiving element. A device for confirming film insertion into a spool according to claim 1, wherein a drive source for feeding the film through a film guide chute is stopped and driving of a take-up shaft of the spool is started.
