Abstract
Abstract The disclosure pertains to a reader for an embossed print element which senses the recessed surface portion of the embossed characters by scanning the characters with a series of sensing indicia which each create a yes or no condition. The sensed signals are superimposed upon a series of timing signals which permit a counter and decoder to identify the character or code element which has been scanned.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
A device for reading indicia on a plate member, said indicia comprising a number of embossments on the upper surface representative of information and having an equal number of recesses on the reverse side, each recess corresponding in position with its respective embossment, comprising: a scanning element having a series of flexibly interconnected first surface portions, each carrying a characteristic form of embossed indicia thereon; drive means for passing said scanning element firSt surface portions sequentially past a debossed character on said reverse side of said plate member; sensing means for indicating when a scanning element first surface portion presents embossments that match and are received in a confronting character debossment; and wherein said scanning element first surface portions are arranged in a predetermined sequence wherein the first of said first surface portion embossed indicia to register with and be received in a confronting debossed character is indicative of the character sensed.
Claim 2
Independent Claim
152 words
A device for reading indicia on a plate member, said indicia comprising a number of embossments on the upper surface representative of information and having an equal number of recesses on the reverse side, each recess corresponding in position with its respective embossment, comprising: a scanning element having a series of flexibly interconnected first surface portions, each carrying a characteristic form of embossed indicia thereon; drive means for passing said scanning element firSt surface portions sequentially past a debossed character on said reverse side of said plate member; sensing means for indicating when a scanning element first surface portion presents embossments that match and are received in a confronting character debossment; and wherein said scanning element first surface portions are arranged in a predetermined sequence wherein the first of said first surface portion embossed indicia to register with and be received in a confronting debossed character is indicative of the character sensed.
Claim 3
Dependent Claim
57 words
The combination of claim 1 wherein said scanning element first surface portions move past said character horizontal centerline in a direction substantially parallel to the vertical axis of said debossed character and said scanning element embossed indicia are coincident with debossed portions of the character corresponding thereto which extend parallel to the vertical axis of such character.
Claim 4
Dependent Claim
60 words
The combination of claim 1 wherein said scanning element comprises: a disc having a series of radially separated resilient segments with said first surface portions respectively disposed on surfaces of said segments; and said drive means comprises means for rotating said disc to bring said first surface portions in sequential biased contact with one of said plate member debossed characters.
Claim 5
Dependent Claim
38 words
The combination of claim 1 wherein said scanning element comprises: a longitudinal strip of material having said first surface portions serially interconnected; and said drive means passes said first surface portions linearly past said plate member debossed character.
Claim 6
Dependent Claim
42 words
The combination of claim 4 wherein said scanning element embossed indicia extend generally parallel to the direction of travel of said scanning element as said scanning element is moved in engaging contact with said plate member past the debossed character being sensed.
