ABSTRACT:
A film cartridge holding device is provided which smoothly socket-connects with and precisely positions the spool shaft in a film cartridge. The film cartridge holding device has two holding shafts oppositely mounted in a film cartridge chamber. A rotatably mounted first holding shaft supports a first end of the spool shaft. The first holding shaft has a driving member which is axially slidable and biased toward the spool shaft. The driving member has a spool engagement member which angularly engages with the first end of the spool shaft. The driving member withdraws to allow the film cartridge to be loaded into the film cartridge chamber, if necessary. A second holding shaft opposite the first holding shaft supports a second end of the spool shaft and compliantly urges the spool shaft toward the first holding shaft.
