Abstract
Abstract An information reader has a number of linear image sensors (1, 1213) dividing one line of picture information into as many parts for reading an original. As these sensors may be relatively shifted in the subscanning directions, signal delay devices (7<sub>11</sub> 7<sub>33</sub>) are provided coresponding to the sensors for delaying a read out signal by an amount corresponding to the respective shift of the image sensors. The invention removes severe constraints on the placement and alignment of the sensors, facilitating installation and maintenance.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A picture information reading apparatus, comprising; a plurality of linear image sensors (1 1 1 2 ,1 3 ) for dividing one line of picture information into parts in a main scanning direction, so as respectively to read said one line of picture information in said parts, and picture signal delaying means (7) provided respectively corresponding to said plurality of linear image sensors, for correcting a sub-scanning direction shift in reading positions between said image snesors by delaying picture signals by an amount corresponding to said shift; whereby the picture signal produced from each of said linear image sensors is correted by said picture signal delaying means so that corrected picture signals are successively read.
Claim 2
Dependent Claim
115 words
A picture information reading apparatus, comprising; a plurality of linear image sensors (1 1 1 2 ,1 3 ) for dividing one line of picture information into parts in a main scanning direction, so as respectively to read said one line of picture information in said parts, and picture signal delaying means (7) provided respectively corresponding to said plurality of linear image sensors, for correcting a sub-scanning direction shift in reading positions between said image snesors by delaying picture signals by an amount corresponding to said shift; whereby the picture signal produced from each of said linear image sensors is correted by said picture signal delaying means so that corrected picture signals are successively read.
Claim 3
Dependent Claim
19 words
An apparatus as claimed in claim 1, said picture signal delaying means comprising buffer means and data selector means.
Claim 4
Dependent Claim
32 words
An apparatus as claimed in claim 2, said buffer means comprising a plurality of serially connected shift registers, an ouput of each said shift register being applied to said data selector means.
Claim 5
Dependent Claim
21 words
An apparatus as claimned in claim 2, said picture signals being applied directly to said data selectors, bypassing said buffer means.
Claim 6
Dependent Claim
33 words
An apparatus as claimed in claim 2, further including timing generator means for outputting validating signals, and gate means receiving said validating signals as well as output signals from said data selector means.
