Abstract
A photograph processing device includes an automatic negative mask section having a film slot and a cartridge setting unit at the film slot. A guide guides a film separated from a cartridge into the film slot. The guide is removably attached to the cartridge setting unit. The guide is attached to a periphery of the cartridge setting unit by a hinge to be integral therewith.
Claims13
A photographic processing device including an automatic mask section comprising:
- a film slot;
- a cartridge setting unit for receiving a cartridge having a film therein, said cartridge setting unit being located at a position such that when the cartridge is received therein the film may be withdrawn from the cartridge at a level and in an angular direction directly aligned with said film slot then and introduced into said film slot;
- and
- a guide detachably mounted relative to said cartridge setting unit to enable guiding of a strip film at said level and in said angular direction into said film slot.
A photographic processing device including a film holder for holding a cartridge having therein film on a spool, said film holder comprising:
- two holding blocks mounted at positions to be on opposite sides of a cartridge to be positioned between said holding blocks;
- each said holding block having a rack gear extending in a direction toward the other said holding block;
- a pinion engaging said racks of said holding blocks, such that movement of one said holding block in a first direction causes movement of the other said holding block in an opposite second direction, whereby said holding blocks are movable toward and away from each other;
- and
- said holding blocks having respective retaining shafts at positions to be engageable with engaging holes of the spool of the cartridge when the holding blocks are moved toward each other, whereby the cartridge can be retained in position by said retaining shafts.
A rotary driving device for rotating a cartridge spool having film thereon and having an indication plate rotatable therewith to selected angular positions indicative of respective conditions of the film, said rotary driving device comprising:
- a driving shaft to be inserted into the spool;
- rotary driving means for rotating said driving shaft in opposite directions to thereby enable the spool to be rotated in opposite directions to unwind film from and wind the film on the spool;
- position detecting means for detecting an angular position of said driving shaft to be indicative of a selected angular position of the indication plate and for outputting a signal representative thereof, said position detecting means comprising an optically detectable mark on said driving shaft, and an optical sensor for detecting a position of said mark;
- and
- control means, responsive to said signal, for controlling said rotary driving means to stop rotation of said driving shaft at a position whereat the indication plate will be stopped at the selected angular position.
A photographic processing device including a rotary driving device for rotating a cartridge spool having film thereon, said rotary driving device comprising:
- an indication plate to be fixed to the spool to be rotatable therewith to selected angular positions indicative of respective conditions of the film;
- a driving shaft to be inserted into the spool;
- rotary driving means for rotating said driving shaft in opposite directions to thereby enable the spool to be rotated in opposite directions to unwind film from and wind the film on the spool;
- position detecting means for detecting an angular position of said driving shaft indicative of a selected angular position of said indication plate and for outputting a signal representative thereof, said position detecting means comprising an optically detectable mark on said driving shaft, and an optical sensor for detecting a position of said mark;
- and
- control means, responsive to said signal, for controlling said rotary driving means to stop rotation of said driving shaft at a position whereat said indication plate will be stopped at said selected angular position.
