Abstract
Abstract A reprographic camera suited for use in daylight conditions has a light-tight casing mounted on its rear-side in which casing is provided with dispensing means for dispensing the required amount of photosensitive material from a supply roll contained therein, a positioning mechanism for positioning the photosensitive material in the middle of the image plane and an optical processing station. The dispensing and positioning are controlled by synchronous motors which are energized for an adjustable period of time which depends on the length of sensitive material to be dispensed and positioned.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
166 words
A reprographic camera for waste-free exposure of photosensitive material under daylight conditions comprising a camera body having a fixed defined image plane and a light-tight casing mounted on its rear-side spaced from said image plane, a supply roll of a continuous web of photosensitive material situated within said casing, dispensing means associated with said casing for advancing outside said casing a selected variable length of the web of photosensitive material from said supply roll, severing means situated between said dispensing means and said image plane for separating from the material web the thus-advanced adjustable length thereof, transport means downstream of said severing means for transporting said severed variable length of material to an exposure position within the image plane of said reprographic camera, separate time-controlled synchronous motors for operating said dispensing means and transport means respectively at substantially fixed rates, and control means for energizing said synchronous motors for lengths of time which are a function of the selected variable length of material to be exposed.
Claim 2
Dependent Claim
166 words
A reprographic camera for waste-free exposure of photosensitive material under daylight conditions comprising a camera body having a fixed defined image plane and a light-tight casing mounted on its rear-side spaced from said image plane, a supply roll of a continuous web of photosensitive material situated within said casing, dispensing means associated with said casing for advancing outside said casing a selected variable length of the web of photosensitive material from said supply roll, severing means situated between said dispensing means and said image plane for separating from the material web the thus-advanced adjustable length thereof, transport means downstream of said severing means for transporting said severed variable length of material to an exposure position within the image plane of said reprographic camera, separate time-controlled synchronous motors for operating said dispensing means and transport means respectively at substantially fixed rates, and control means for energizing said synchronous motors for lengths of time which are a function of the selected variable length of material to be exposed.
Claim 3
Dependent Claim
26 words
A daylight reprographic camera according to claim 1, in which said transport means comprises synchronously driven rollers in frictional engagement with the rear-side of the latter.
Claim 4
Dependent Claim
46 words
A daylight reprographic camera according to claim 1, in which said transport means are movable bodily towards and away from said image plane and including means for moving said rollers into transporting relationship with said photosensitive material only during the time of transport of the latter.
Claim 5
Dependent Claim
19 words
A daylight reprographic camera according to claim 3, in which said transport means are mounted on a balance arm.
Claim 6
Dependent Claim
22 words
A daylight reprographic camera according to claim 4, in which said moving means comprises an electromagnet operatively connected to said balance arm.
Claim 7
Dependent Claim
24 words
A daylight reprographic camera according to claim 1, which comprises additional transporting means for advancing the exposed photosensitive material out of the image plane.
Claim 8
Dependent Claim
22 words
A daylight reprographic camera according to claim 1, which further comprises a processing station for processing the photosensitive material after its exposure.
Claim 9
Dependent Claim
29 words
A daylight reprographic camera according to claim 7, which further comprises a diffusion station and means to transport said photosensitive material from said processing station to said diffusion station.
Claim 10
Dependent Claim
19 words
A daylight reprographic camera according to claim 8, in which said diffusion station is located above said processing station.
Claim 11
Dependent Claim
32 words
A daylight reprographic camera according to claim 1, in which a light opaque platen is provided over the image plane, which is provided with openings through which sand transport means partly protrude.
Claim 12
Dependent Claim
30 words
A daylight reprographic camera according to claim 1, wherein said control means operates said transport means to position said selected variable length of material symmetrically lengthwise with said image plane.
