Abstract
The hinged image holder of a photographic enlarger has its upper portion loosely attached to the lamp housing so that it is automatically opened for inserting and removing original images when the lamp housing is moved away from the rest of the enlarger. The lamp housing may be hinged or move parallel to the rest of the enlarger. The upper part of the holder is loosely attached to the lamp housing by variously shaped clips or slots which engage corresponding portions on the lamp housing.
Claims6
An image holding arrangement for a photographic enlarger having a lamp housing and a lens compartment separate from each other, movable means connecting the lamp housing to the lens holding compartment for movement of the lamp housing away from and towards the lens holding compartment, a hinged image holder disposed between adjacent portions of the lamp housing and lens holding compartment, the image holder having substantially flat upper and lower portions hinged to each other, and loose coupling means connecting the upper portion of the image holder to the lamp housing whereby movement of the lamp housing away from the lens holder automatically opens the image holder for insertion and removal of image material.
