Abstract
Abstract When the lines of information from an original do not coincide with the image sensors, image from one line can be logically combined to provide a signal representing the presence or absence of image on that line.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
An information reading device comprising a sensor having a plurality of sensing elements receiving an image of an original document through an optical system, said original document having respective lines of information thereon separated by first intervals, said sensing elements not aligned with said lines of information separated by said first intervals such that the lines of information in the image received by said sensing elements are not aligned with said sensing elements, and logic means for combining selected sensor element outputs to obtain signals representing information on respective lines.
Claim 2
Dependent Claim
90 words
An information reading device comprising a sensor having a plurality of sensing elements receiving an image of an original document through an optical system, said original document having respective lines of information thereon separated by first intervals, said sensing elements not aligned with said lines of information separated by said first intervals such that the lines of information in the image received by said sensing elements are not aligned with said sensing elements, and logic means for combining selected sensor element outputs to obtain signals representing information on respective lines.
Claim 3
Dependent Claim
55 words
A reading device as claimed in claim 1, wherein said logic means is switchable to provide at least first and second different sets of output signals in response to said sensor element output signals, said first and second sets of output signals corresponding to different original documents having first and second different information line intervals.
Claim 4
Dependent Claim
55 words
A reading device as claimed in claim 2, wherein in a first mode said logic means provides said sensor outputs directly as indications of information contained within respective lines, and in a second mode said logic means selects at least a portion of its output signal set from a logical combination of sensor element outputs.
Claim 5
Dependent Claim
42 words
A reading device as claimed in claim 3, wherein said at least portion of said output signal set includes at least one logical OR combination of outputs from at least two sensor elements overlapped by the image from a single information line.
Claim 6
Dependent Claim
55 words
A reading device as claimed in claim 2, wherein one of said sensor elements always represents information from a line containing information to be transmitted and the remaining sensor elements detect the presence or absence of information on subsequent lines while the information of said first line is being read by said one sensor element.
Claim 7
Independent Claim
107 words
A method of reading information in a multiline concurrent scanning type original document reader, said reader having a plurality of sensors for receiving through an optical system an image of information from said original document, said original having a plurality of lines of information thereon, said method comprising: forming an image of said original on said sensing elements such that at least one of the lines of information in said image overlaps at least a first and a second of said sensor elements; and logically combining outputs from said first and second sensor elements to obtain a signal representing the information of said at least one line.
Claim 8
Independent Claim
107 words
A method of reading information in a multiline concurrent scanning type original document reader, said reader having a plurality of sensors for receiving through an optical system an image of information from said original document, said original having a plurality of lines of information thereon, said method comprising: forming an image of said original on said sensing elements such that at least one of the lines of information in said image overlaps at least a first and a second of said sensor elements; and logically combining outputs from said first and second sensor elements to obtain a signal representing the information of said at least one line.
Claim 9
Dependent Claim
56 words
A method as claimed in claim 6, wherein said step of logically combining comprises providing a first combination of said sensor output signals indicating respective lines of image information for an original having a first interval between lines and a second combination of signals representing image information for an original having a second interval between lines.
Claim 10
Dependent Claim
62 words
A method as claimed in claim 7, wherein said step of providing said first combination of said sensor output signals comprises providing said sensor output signals directly as indications of information on respective lines and wherein said step of providing said second combination of output signals comprises providing a logical OR combination of at least said first and second sensor element outputs.
Claim 11
Dependent Claim
35 words
A method as claimed in claim 6, wherein one of said sensor elements reads information from a line being transmitted and the remaining sensor elements detect the presence or absence of information on subsequent lines.
Claim 12
Dependent Claim
32 words
A method as claimed in claim 9, further comprising the step of advancing said original such that said line to be transmitted is always in substantial registration with said one sensor element.
