ABSTRACT:
A locking device for use in a processing device for processing photosensitive material such as photographic film has a light-shield cover that can be unlocked without moving a knob plate. The knob plate has an engaging member for locking the light-shield cover. An unlocking mechanism is provided to unlock the light-shield cover without moving the knob plate. The unlocking mechanism has a pushing head, and an unlocking lever having a tip engageable with the engaging member and adapted to be pushed by the pushing head. By moving the unlocking lever with the pushing head until its tip disengages from the engaging member, the engaging member can pass through a cutout, so that the light-shield cover can be unlocked and opened.
