Abstract
Abstract An improvement for use with an automatic print cutter mechanism which is actuated by sensing control indicia positioned along a continuous strip of photographic prints, said improvement comprising a wide scanning angle sensor capable of detecting said indicia of numerous configurations when same are misaligned with respect to the center line of said sensor and means for independent lateral and transverse adjustment of said sensor.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
93 words
An improvement for use with a photographic print cutter mechanism which includes a power driven strip conveyor for conveying a strip of photographic prints having control indicia positioned along a marginal edge portion thereof, said conveyor including control means actuated by sensing the control indicia, said improvement comprising: a wide scanning photovoltaic sensor positioned to scan the marginal edge portion of the strip which bears the control indicia, said sensor scanning an area of at least 0.250 inches wide to detect a multiplicity of different configurations, sizes and placements of said control indicia.
Claim 2
Dependent Claim
93 words
An improvement for use with a photographic print cutter mechanism which includes a power driven strip conveyor for conveying a strip of photographic prints having control indicia positioned along a marginal edge portion thereof, said conveyor including control means actuated by sensing the control indicia, said improvement comprising: a wide scanning photovoltaic sensor positioned to scan the marginal edge portion of the strip which bears the control indicia, said sensor scanning an area of at least 0.250 inches wide to detect a multiplicity of different configurations, sizes and placements of said control indicia.
Claim 3
Dependent Claim
20 words
The improvement set forth in claim 1 wherein said sensor includes a source of radiant energy in the infrared spectrum.
Claim 4
Dependent Claim
46 words
The improvement set forth in claim 1 and further comprising: a source of radiant energy, and the source of radiant energy and the wide scanning angle sensor in predetermind spaced relationship while the strip conveyor transports the strip of prints bearing the said control indicia therebetween.
Claim 5
Dependent Claim
95 words
An improvement for use with a photographic print cutter mechanism which includes a print cutter with actuating means therefor and a driven strip conveyor and which is automatically actuated by sensing control indicia positioned along a marginal edge portion of a continuous strip of photographic prints, said improvement comprising: a wide scanning angle photovoltaic sensor positioned to scan the marginal edge portion of the strip which bears the control indicia, said sensor scanning an area of at least 0.250 inches wide to detect a multiplicity of different configurations, sizes and placements of said control indicia.
Claim 6
Dependent Claim
95 words
An improvement for use with a photographic print cutter mechanism which includes a print cutter with actuating means therefor and a driven strip conveyor and which is automatically actuated by sensing control indicia positioned along a marginal edge portion of a continuous strip of photographic prints, said improvement comprising: a wide scanning angle photovoltaic sensor positioned to scan the marginal edge portion of the strip which bears the control indicia, said sensor scanning an area of at least 0.250 inches wide to detect a multiplicity of different configurations, sizes and placements of said control indicia.
Claim 7
Dependent Claim
20 words
The improvement set forth in claim 4 wherein said sensor includes a source of radiant energy in the infrared spectrum.
Claim 8
Dependent Claim
27 words
The improvement set forth in claim 4 and further including conditioning means to condition the output of said sensor for use in controlling the cutter actuating means.
Claim 9
Dependent Claim
112 words
The improvement of claim 4 further comprising: first adjusting means for adjusting the position the wide scanning angle photovoltaic sensor in a plane parallel to the marginal edge of the strip print; first guide means for restricting the adjustment by the first adjusting means to the parallel plane; second adjusting means for adjusting the position the wide scanning angle photovoltaic sensor in a plane normal to the path of the strip of prints; and second guide means for restricting the adjustment by the second adjusting means to the normal plane, wherein adjustment of the wide scanning angle photovoltaic in the planes parallel and normal to the strip are independent of one another.
