Optical character reader

Claim 1

An optical character reading comprising: a hand-held image sensing means for simultaneously scanning a plurality of characters on a line of print and producing analog signals in response thereto that correspond to image elements sensed; binary signal generating means for generating binary data responsive to said analog signals which are received from said image sensing means; scanned position detecting means for determining whether the characters scanned were completely within the field of vision of said scanning means, said scanned position detecting means including means for truncating the binary data if said scanned position detecting means determines that some of the characters are not fully within the field of vision of the sensing means so that further processing of the truncated binary data does not occur and processing speed is increased; memory means for storing said binary data; one character pick out means for separating binary data from said memory means corresponding to n individual characters; and recognition processing means for identifying the individual character separated by said pick out means, whereby an entire printed line of characters, N being a predetermined number of individual characters, may be scanned and identified without having to move the scanner from one character to another.

Claim 5

A method of mechanically scanning and recognizing printed characters comprising: (a) scanning a plurality of individual characters simultaneously with a hand-held analog sensing device; (b) converting the analog signal outputted from the sensing device into binary data; (c) determining whether the characters scanned were completely within the range of vision of said hand-held analog sensing device; (d) truncating the binary data if the characters scanned were not completely within the field of vision of said hand-held analog sensing device so that further processing of the truncated binary data does not occur and processing speed is increased; (e) separating the binary data corresponding and to a single character from the remainder of said data if the characters scanned in were completely within the field of vision of said hand-held analog sensing device; (f) processing the binary data for said single character to identify the character.

Claim 6

A method of mechanically scanning and recognizing printed characters comprising: (a) scanning a plurality of individual characters simultaneously with a hand-held analog sensing device; (b) converting the analog signal outputted from the sensing device into binary data; (c) determining whether the characters scanned were completely within the range of vision of said hand-held analog sensing device; (d) truncating the binary data if the characters scanned were not completely within the field of vision of said hand-held analog sensing device so that further processing of the truncated binary data does not occur and processing speed is increased; (e) separating the binary data corresponding and to a single character from the remainder of said data if the characters scanned in were completely within the field of vision of said hand-held analog sensing device; (f) processing the binary data for said single character to identify the character.
