Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
Apparatus for making a record, comprising: a flexible tape having a transparent portion and an opaque portion; a stylus having a sharp cutting point thereon adapted to engage said opaque portion of said flexible tape; means mounting said tape for longitudinal movement relative to said stylus; means mounting said stylus for resiliently urging said sharp cutting point of said stylus relative to and in a direction towards said tape for cutting through said opaque portion of said tape as said tape is moved longitudinally relative to said stylus; means for moving said stylus laterally relative to said tape as said tape moves longitudinally relative to said stylus; and guide plate means having a guide surface in sliding engagement with a portion of said stylus at all times so as to limit the movement of said stylus in the direction towards said tape at all times for thereby limiting the depth of the cut by said cutting point of said stylus as it moves relative to said tape to prevent cutting through said transparent portion.
Claim 2
Dependent Claim
174 words
Apparatus for making a record, comprising: a flexible tape having a transparent portion and an opaque portion; a stylus having a sharp cutting point thereon adapted to engage said opaque portion of said flexible tape; means mounting said tape for longitudinal movement relative to said stylus; means mounting said stylus for resiliently urging said sharp cutting point of said stylus relative to and in a direction towards said tape for cutting through said opaque portion of said tape as said tape is moved longitudinally relative to said stylus; means for moving said stylus laterally relative to said tape as said tape moves longitudinally relative to said stylus; and guide plate means having a guide surface in sliding engagement with a portion of said stylus at all times so as to limit the movement of said stylus in the direction towards said tape at all times for thereby limiting the depth of the cut by said cutting point of said stylus as it moves relative to said tape to prevent cutting through said transparent portion.
Claim 3
Dependent Claim
98 words
The structure set forth in claim 1, wherein: said means mounting said stylus includes a pivot mounting means for pivotally moving said point of said stylus and disposed near one longitudinal side of said tape; and said guide plate means includes an upper edge which is shaped to correspond approximately to the path of lateral movement of said sharp cutting point of said stylus so that said stylus is guided as it pivots about said pivot mounting means but so that said guide plate does not interfere with the lateral movements of said stylus relative to said tApe.
Claim 4
Dependent Claim
25 words
The apparatus set forth in claim 1, wherein: the thickness of said opaque portion is thin as compared to the thickness of said transparent portion.
Claim 5
Dependent Claim
31 words
The apparatus set forth in claim 3, wherein: said transparent portion is a flexible plastic; and said opaque portion is a metal layer which has been deposited on said transparent portion.
Claim 6
Dependent Claim
57 words
The apparatus set forth in claim 1, including: a platen over which said tape is adapted to move and which is disposed opposite said stylus; and reel means supporting said tape for movement across said platen, including a supply reel on one side of said platen and a take-up reel on the other side of said platen.
