Abstract
Abstract A character and image processing apparatus comprises a scanning section (9) for photoelectrically convertIng data on a sheet (1) in which character data (2) and image data (3) are mixediy arranged in a free format; an image buffer (10) for storing the photoelectrically converted data; a scanning control circuit (11) for scanning the stored data in the image buffer (10) to detect control marks (4, 5, 6, 7, 8) and for determining a character read mode, an image data output mode or a skip mode according to the control mark; a character recognizing circuit (12) for recognizing characters from the image buffer (10) when the scanning control circuit (11) determines the control marks (4, 5, 6, 7, 8) as the character read mode; a data compression circuit (13) for compressing the image data from the image buffer (10) when the scanning control circuit (11) determines the control marks (5, 7, 8) as the image data output mode; and a data editing circuit (14) for discriminately editing the character data and the image data.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
190 words
A character and image processing apparatus having a scanning section (9) for scanning a sheet (1) and for photoelectrically converting the scanned data; storage means (10) for storing the photoelectrically converted data; character recognizing means (12) and image data processing means (13, 14) characterized in that these are further provided with control mark means (4, 5, 6, 7, 8) for designating data areas to be processed cessed on a sheet (1); and control means (11) for scanning the stored data in said storage means (10) to detect said control mark means (4, 5, 6, 7, 8) and for determining a character read mode or an image data output mode according to said control mark means (4, 5, 6, 7, 8) so that said character recognizing means (12) recognizes characters from said storage means (10) when said control means (11) determines said control mark means (4, 5, 6, 7, 8) as the character read mode and said image data processing means (13, 14) processes image data from said storage means (10) when said control means (11) determines said control mark means (4, 5, 6, 7, 8) as the image output mode.
Claim 2
Dependent Claim
190 words
A character and image processing apparatus having a scanning section (9) for scanning a sheet (1) and for photoelectrically converting the scanned data; storage means (10) for storing the photoelectrically converted data; character recognizing means (12) and image data processing means (13, 14) characterized in that these are further provided with control mark means (4, 5, 6, 7, 8) for designating data areas to be processed cessed on a sheet (1); and control means (11) for scanning the stored data in said storage means (10) to detect said control mark means (4, 5, 6, 7, 8) and for determining a character read mode or an image data output mode according to said control mark means (4, 5, 6, 7, 8) so that said character recognizing means (12) recognizes characters from said storage means (10) when said control means (11) determines said control mark means (4, 5, 6, 7, 8) as the character read mode and said image data processing means (13, 14) processes image data from said storage means (10) when said control means (11) determines said control mark means (4, 5, 6, 7, 8) as the image output mode.
Claim 3
Dependent Claim
81 words
A character and image processing apparatus according to claim 1, wherein said control mark means (4, 5, 6, 7, 8) is one or more vertical bars (4, 5, 6) marked or printed in an empty area of the sheet (1) in a perpendicular direction to the character lines (2) and said control means (11) controls the switching of the character read mode and the image data output mode in accordance with the number and position of the bars (4, 5, 6).
Claim 4
Dependent Claim
45 words
A character and image processing apparatus according to claim 2, wherein a whole area at right side of the sheet corresponding to the vertical bar or bars detected by said control means (11) is treated as a character-read area or an image data output area.
Claim 5
Dependent Claim
102 words
A character and image processing apparatus according to claim 1, wherein said control mark means (4, 5, 6, 7, 8) are one or more vertical bars (4, 5) marked or printed in an empty area of the sheet in a perpendicular direction to the character lines and one or more horizontal bars (7, 8) marked or printed in a horizontal direction to the character lines and said control means (11) controls the switching of the character read mode and the image data output mode in accordance with the numbers and positions of the vertical and the horizontal bars (4, 5, 7, 8).
Claim 6
Dependent Claim
55 words
A character and image processing apparatus according to claim 4, wherein a two-dimensionally limited area at a right side of the sheet corresponding to the vertical bar (4) or bars (5) and the horizontal bar or bars detected by said control means (11) is treated as a character-read area or an image data output area.
Claim 7
Dependent Claim
61 words
A character and image processing apparatus according to claim 1, wherein said control mark means (4, 5, 6, 7, 8) is a timing mark (16) in an empty area of the sheet and said control means (11) controls the switching of the character read mode and the image data output mode in accordance with the detection of the timing mark (16).
Claim 8
Dependent Claim
