Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
68 words
Apparatus for punching code notches in the edge of a data carrier said code having a plurality of predetermined notch positions comprising: punch means mounted in juxtaposition with said edge of said carrier; means for sequentially indexing said punch means to each of said notch positions; memory means for storing coded data; toggle means responsive to said memory means for actuating said punch means to notch said carrier.
Claim 2
Dependent Claim
68 words
Apparatus for punching code notches in the edge of a data carrier said code having a plurality of predetermined notch positions comprising: punch means mounted in juxtaposition with said edge of said carrier; means for sequentially indexing said punch means to each of said notch positions; memory means for storing coded data; toggle means responsive to said memory means for actuating said punch means to notch said carrier.
Claim 3
Dependent Claim
84 words
Apparatus as in claim 1 where said toggle means includes first and second toggle links coupled together at one end and to a pull link, the other end of said first link being mounted on a fixed pivot and the other end of said second link being pivoted to said punch means said punch means being slidably mounted, together with solenoid means for moving said pull link whereby said toggle links are straightened and said punch means slide into engagement with said carrier edge.
Claim 4
Dependent Claim
90 words
Apparatus as in claim 1 together with means for positioning said carrier including means for detecting the presence of said edge of said carrier, means responsive to said detection of said edge for backstopping the edge of said carrier opposite said detected edge, means for pushing said carrier against said backstopping means, means responsive to said pushing means for clamping said carrier against movement, and means responsive to actuation of said clamping means for actuating said toggle means for notching said carrier edge in accordance with said stored coded data.
Claim 5
Dependent Claim
19 words
Apparatus as in claim 3 where said edge detecting means is mounted for indexed movement with said punch means.
Claim 6
Dependent Claim
31 words
Apparatus as in claim 3 together with means for detecting the side orientation of said film carrier and for inhibiting operation of said toggle means if said side orientation is erroneous.
Claim 7
Dependent Claim
23 words
Apparatus as in claim 1 where said punch means is mounted at a predetermined angle with respect to a perpendicular to said carrier.
Claim 8
Dependent Claim
22 words
Apparatus as in claim 1 together with verification means for verifying said punched notches mounted for indexed movement with said punch means.
Claim 9
Dependent Claim
19 words
Apparatus as in claim 7 where said verification means includes a light source and photo-sensor for sensing individual notches.
Claim 10
Dependent Claim
28 words
Apparatus as in claim 1 where said toggle means includes means for adjusting the travel of said punch means to breaking through said edge but traveling no further.
Claim 11
Dependent Claim
30 words
Apparatus as in claim 9 where said adjusting means includes an adjustment not coupled to a link of said toggle means along with a lock screw for locking said nut.
Claim 12
Dependent Claim
34 words
Apparatus as in claim 1 together with means for positioning said carrier including a fixed lateral guide and a spring loaded lateral guide said carrier having a reference edge which engages said fixed guide.
