Abstract
Abstract A self-contained camera, photoprinting and processing machine in which the interior of the camera is accessible to the operator through a lighttight sleeve carried by a horizontally movable flat strip. Operations within the camera are visible through a light-filtering window which prevents ambient light from exposing the photographic paper or film within the camera. The copy holder is illuminated by swingable lamp holders and the lamps rocked to prevent hot spots on the copy. Vacuum means are used to hold the light-sensitive paper upon a platen while it is being positioned.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
168 words
A combined photoprinting and processing device comprising a base, a camera housing on top of said base, a copy board adjustably carried at one side of said base, a photographic processor carried on the opposite side of said base, means to illuminate the copy board, means to receive the light coming from the copy board and direct it into the camera housing, a longitudinally movable platen within the camera housing to receive the light directed into the housing, means to hold a sheet of light-sensitive record material on said platen, a lightfiltering window on the camera housing to screen out light to which the record material is sensitive, an elongated longitudinally movable belt in the form of a continuous band supported by rollers carried by the camera housing and overlying a portion of the window, lighttight access means carried by the belt whereby the operator may reach within the camera housing and means accessible to the front of the base to carry out the photoprinting and processing operations.
Claim 2
Dependent Claim
168 words
A combined photoprinting and processing device comprising a base, a camera housing on top of said base, a copy board adjustably carried at one side of said base, a photographic processor carried on the opposite side of said base, means to illuminate the copy board, means to receive the light coming from the copy board and direct it into the camera housing, a longitudinally movable platen within the camera housing to receive the light directed into the housing, means to hold a sheet of light-sensitive record material on said platen, a lightfiltering window on the camera housing to screen out light to which the record material is sensitive, an elongated longitudinally movable belt in the form of a continuous band supported by rollers carried by the camera housing and overlying a portion of the window, lighttight access means carried by the belt whereby the operator may reach within the camera housing and means accessible to the front of the base to carry out the photoprinting and processing operations.
Claim 3
Dependent Claim
40 words
A device according to claim 1 in which the copy board is vertically adjustable and the illuminating means comprises lamps mounted in lamp holders and supported by elongated outwardly extending brackets responsive to the vertical adjustment of the copy board.
Claim 4
Dependent Claim
38 words
A device according to claim 2 in which the lamps are swingably mounted in the lamp holders and a motor driven cam is coupled to said lamp mounts to oscillate the lamps during the operation of the camera.
Claim 5
Dependent Claim
53 words
A device according to claim 2 in which the base is provided with a gear rack, a gear train is in mesh with the gear rack and belt means within the copy board and driven by the gear train change the position of the lamp holders as the copy board is moved vertically.
Claim 6
Dependent Claim
74 words
A device according to claim 2 in which the brackets are in the form of spaced links of unequal length, the shorter links being coupled at one end to the lower portion of the lamp holders and the longer links being coupled to the top portion of the lamp holders, said links being driven by outwardly extending arms carried by the copy board and being pivotally secured at their opposite ends to the base.
Claim 7
Dependent Claim
47 words
A device according to claim 1 in which the platen sheet holding means includes a source of vacuum, a plurality of holes in the platen in communication with the vacuum source and a transparent plate swingably carried by the platen and overlying the sheet receiving face thereof.
Claim 8
Dependent Claim
70 words
A device according to claim 6 in which the vacuum source is applied to the platen through a rotatably mounted header, said header having a sinuous slot in the wall thereof and a longitudinally slit sleeve within the header, a coupling slidably received within the sinuous slot and longitudinal slit and a pipe interconnecting the coupling and platen holes whereby vacuum is applied to the platen during all platen positions.
Claim 9
Dependent Claim
32 words
A device according to claim 6 in which the transparent plate is responsive to the longitudinal motion of a ''''Z''''-bar driven by actuating means extending outwardly of the front of the base.
