Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
An apparatus for optically reading characters from any of a plurality of record media having lines of characters at different heights, comprising: a housing; means in said housing for defining a gap through which a record medium may be passed; optical reader means in said housing near said gap reading characters from the record medium passing through said gap; means for adjusting a height of said optical reader means including an adjustment dial on an outer surface of said housing; and means, visible from outside said housing, for indicating the height of said optical reader means, said indicating means being positioned adjacent said gap so that the indicated height of said optical reader means can readily and directly be compared to a line of characters on a portion of the record medium which extends out of said gap.
Claim 2
Independent Claim
138 words
An apparatus for optically reading characters from any of a plurality of record media having lines of characters at different heights, comprising: a housing; means in said housing for defining a gap through which a record medium may be passed; optical reader means in said housing near said gap reading characters from the record medium passing through said gap; means for adjusting a height of said optical reader means including an adjustment dial on an outer surface of said housing; and means, visible from outside said housing, for indicating the height of said optical reader means, said indicating means being positioned adjacent said gap so that the indicated height of said optical reader means can readily and directly be compared to a line of characters on a portion of the record medium which extends out of said gap.
Claim 3
Dependent Claim
30 words
The apparatus according to claim 1, wherein said indicating means and said adjusting means are provided on the same side of said housing as the record medium may be inserted.
Claim 4
Dependent Claim
83 words
The apparatus according to claim 1, wherein said adjusting means further comprises a second dial, which shares a common shaft with said adjustment dial, and means attached to said adjustment dial for holding said reader means in its adjusted position by tightening said second dial so as to secure said attached means between said reader means and said second dial, said second dial being tightened by turning it on said shaft, thereby moving upward and pushing said attached means against said reader means.
Claim 5
Dependent Claim
19 words
The apparatus according to claim 1, wherein said indicating means comprises an electronic pointer formed by light emitting diodes.
