Abstract
Abstract A device for maintaining films and panels in close tolerance registration. The device includes an upper leaf and a lower leaf which are selectively joined together by zero-tolerance snap connectors. The upper leaf and lower leaf are adapted to improve device wear characteristics and, as well, to improve the operation of the system which uses the registration device of the instant invention.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
A registration device comprising, a pair of planar members having relatively large surface area, said planar members fabricated of a material which is selected to be substantially transparent to a specified radiation, connector means mounted at two or more corners of said pair of planar members to permit said planar members be selectively connected and disconnected, and registration means mounted at at least one of said planar members for establishing registration of said pair of planar members and materials held therebetween.
Claim 2
Dependent Claim
81 words
A registration device comprising, a pair of planar members having relatively large surface area, said planar members fabricated of a material which is selected to be substantially transparent to a specified radiation, connector means mounted at two or more corners of said pair of planar members to permit said planar members be selectively connected and disconnected, and registration means mounted at at least one of said planar members for establishing registration of said pair of planar members and materials held therebetween.
Claim 3
Dependent Claim
19 words
The device recited in claim 1 wherein, said planar members have lengthwise grooves scored in the outer surfaces thereof.
Claim 4
Dependent Claim
33 words
The device recited in claim 1 including, spacer means disposed on at least one of said planar members so that the planar members remain spaced apart even when connected by said connector means.
Claim 5
Dependent Claim
30 words
The device recited in claim 1 wherein, said registration means comprises a pin mounted on one of said planar members and communicating with an aperture in the other planar member.
Claim 6
Dependent Claim
15 words
The device recited in claim 2 wherein, said grooves have shoulders at the sides thereof.
Claim 7
Dependent Claim
52 words
The registration device recited in claim 1 wherein, said registration means includes a pin comprising, a first body portion which is cylindrical in configuration, a second body portion which has one or more flat sides and extends from said first body portion, and a pointed end thereof adjacent said second body portion.
Claim 8
Dependent Claim
28 words
The registration pin recited in claim 6 wherein, said flat sides of said second body portion are joined by arcuate side portions extended from said first body portion.
Claim 9
Dependent Claim
18 words
The registration device recited in claim 6 wherein, said pointed end comprises a conical point of about 45°.
Claim 10
Dependent Claim
108 words
A registration device comprising, pair of planar members each having a relatively large surface area, at least one of said pair of planar members fabricated of a material which is substantially transparent to a specified radiation, at least one of said pair of planar members having lengthwise grooves provided at the outer surface thereof, connector means provided at least two corners of each of said pair of planar members to permit said pair of planar members to be selectively and readily connected and disconnected, and registration means mounted at least one of said pair planar members for establishing registration of said pair of planar members and materials therebetween.
Claim 11
Dependent Claim
108 words
A registration device comprising, pair of planar members each having a relatively large surface area, at least one of said pair of planar members fabricated of a material which is substantially transparent to a specified radiation, at least one of said pair of planar members having lengthwise grooves provided at the outer surface thereof, connector means provided at least two corners of each of said pair of planar members to permit said pair of planar members to be selectively and readily connected and disconnected, and registration means mounted at least one of said pair planar members for establishing registration of said pair of planar members and materials therebetween.
