Abstract
Abstract A step and repeat camera for reducing and reproducing in a repeating manner an object having the pattern to be reproduced on a plurality of photographic plates. The plates are supported on a table slidably mounted on a base and a housing having projection means is slidably mounted above the table. A plurality of apertures is provided in the surface of the housing and a means for accurately orienting and aligning the object over the aperture is movably arranged above the surface of the housing. The object is provided with an aligning mark which is intended to coincide with an aligning mark adjacent each of the apertures. The aligning means comprises a device for moving the object over the surface of the table until the aligning marks are aligned and a microscope is provided for movement with the aligning means for accurate observation to determine when the marks are aligned.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A step and repeat camera for reducing and reproducing in a repeating manner at least one object having the desired pattern on at least one plate of photographic material comprising a base, a table slidably mounted on said base for supporting said plate of photographic material, said plate having successively different areas exposed to the camera, a housing located substantially above said table having a surface for supporting thereon said object, means slidably mounted on said base for supporting said surface, at least one aperture on said surface over which said object is arranged, means within said housing for projecting the pattern of said object through said aperture onto said plate, means for aligning said object over said aperture comprising a first aligning mark on said object and a second aligning mark on said surface, means movably mounted above said surface for moving and orienting said object with respect to said aperture so as to cause said aligning marks to coincide, and a microscope movable with said orienting means for accurately observing the movement of said object so as to precisely align said aligning marks.
Claim 2
Dependent Claim
185 words
A step and repeat camera for reducing and reproducing in a repeating manner at least one object having the desired pattern on at least one plate of photographic material comprising a base, a table slidably mounted on said base for supporting said plate of photographic material, said plate having successively different areas exposed to the camera, a housing located substantially above said table having a surface for supporting thereon said object, means slidably mounted on said base for supporting said surface, at least one aperture on said surface over which said object is arranged, means within said housing for projecting the pattern of said object through said aperture onto said plate, means for aligning said object over said aperture comprising a first aligning mark on said object and a second aligning mark on said surface, means movably mounted above said surface for moving and orienting said object with respect to said aperture so as to cause said aligning marks to coincide, and a microscope movable with said orienting means for accurately observing the movement of said object so as to precisely align said aligning marks.
Claim 3
Dependent Claim
30 words
The camera according to claim 2 wherein said microscope comprises a pair of lenses arranged in side-by-side relation for simultaneous observation of two locations on said aligning marks during orientation.
Claim 4
Dependent Claim
107 words
The camera according to claim 3 further comprising guide means mounted on a side of said housing, a guide block slidably mounted on said guide means for movement in a direction parallel to said surface, a body pivotally connected to said guide block for pivotal movement thereof about an axis parallel to the direction of movement of said guide block, an arm for rigidly supporting therefrom said object orienting means and said microscope movably mounted on said body for movement in a direction perpendicular to the direction of movement of said guide block so that said object may be displaced in either of said directions for orientation.
Claim 5
Dependent Claim
18 words
The camera according to claim 3 further comprising means associated with said arm for angularly positioning said object.
