Film image input device with detachable cartridge holding unit

摘要

In a scanner having a film image input unit for reading images from developed film stowed in a cartridge and a cartridge film holding unit capable of being detachably attached to the image input unit and of holding the cartridge, a locking mechanism is used to restrain the film holding unit from being detached from the image input unit immediately before or after pulling the film out of the cartridge is started. It is therefore possible to prevent the imperfect run or rewind of the cartridge film due to a careless operation. It can also be prevented that loaded film is soiled or flawed.
