Abstract
A storage and viewing device is disclosed for cut film radiographs. The device is provided with a combination of fluorescent lights and a spotlight in a plurality of discrete viewing areas. A transport mechanism moves panel mounted X-rays from a storage area to the viewing area and vice versa. An intermittent drive means is utilized for indexing the display panels into and out of the storage area. Means are provided for controlling the movement of the panels as they are transported to the display area to prevent jamming.
Claims10
In a system for storing and displaying display panel mounted cut film radiographs including:
- a storage area, a display area, and a main conveyor for carrying said panels between said storage and display areas by lifting said panels at one end thereof, the improvement comprising:
- means for positioning and damping pendulum motion of said panels when carried on said conveyor to and from said display area,
- said positioning and damping means including a pair of cams rotated synchronously with said conveyor in a direction corresponding to the direction of movement of said conveyor, said cams positioned to contact the other, free swinging, end of said display panels carried by said conveyor to restrain said swinging end relative to said one end whereby pendulum motion is damped and the panel is correctly positioned for entry to or egress from the display area.
A system for displaying cut film radiographs comprising:
- a. at least two adjacent light compartments each compartment separated from the adjacent compartments by a baffle,
- b. translucent diffuser panels provided over said compartments on which said radiographs are positioned for viewing,
- c. first lighting means in each compartment for over all illumination of said radiograph,
- d. second lighting means in each compartment for spotlighting selected areas of said radiograph,
- e. electrically controlled means for rotational and translational positioning of the second lighting means within said compartment to spotlight substantially any portion of a radiograph,
- said baffle preventing light from one compartment from diffusing into the viewing area of an adjacent compartment thereby to provide a sharp lighting cut off.
