Then, the address count value corresponding to the row address b ₁ at that time is written in the address data memory 67 from the first row address counter 61x via the gate G3. When the detection and storage of the upper edge address of characters is completed in steps B1 to B3, step
Proceed to B4, and further, each character string stored in advance in the address data memory 67 in the character string width detection processing in step S1.
Image data for one row in the first image data memory 60 in each of a _{1 to} a ₂ , a _{3 to} a ₄ , ... Is sequentially designated by the first row address counter 61x via the first address selector 62, It is sent to the data judgment unit 66 via the gate G3 and the parallel / serial 65. Then, in step B5, the data determination unit 66 determines whether or not all the image data sent in the row address order is white data. Here, for example, the image data corresponding to the column address b ₂ in FIG. When sent to the data determination unit 66, the lower end of the character data “H” in FIG.
In, the lower end of the character data “ha” is determined to be white data and the process proceeds to step B6. Then the row address at that time
The address count value corresponding to b ₂ is transferred from the first row address counter 61x via the gate G3 to the address data memory 6
Written on 7. In other words, in steps B4 to B6, the line address at the bottom of the character is detected, and
Each string a ₁ by repeating the process from _{B1, a 2, a 3,} a 4, a width b ₁ of each character in _{..., b 2, b 3,} b 4, so that ... is detected.

When the character width detection process is completed in this way, the process proceeds to step S5 in FIG. 7, and the leftmost address of the first character, for example, the column address a ₁ in FIG. 6 is set as C ₁ in the address data memory 67. Store in another memory. Then, the process proceeds to step S6, where n indicating the number of characters is set to "2", then the process proceeds to step S7, and the process proceeds to step S8 when the nth character "exists".

In this step S8, the address value Cn of the leftmost end of the nth character, that is, the leftmost end of the second character (“I” or “Ma” in FIG. 6 in this case) is detected.

FIG. 10 is a flowchart showing the operation of detecting the deviation width Dmn from other characters with reference to the leftmost column address C ₁ in each character string. First, in steps C1 and C2, the upper and lower ends of the character Each row address indicating b ₁ , b ₂ , b ₃ , b
Column addresses a ₁ , a ₂ , a ₃ , a indicating the left and right edges of characters in ₄ , ...
₄ , ... Is sent to the data judgment unit 66, and the leftmost end of each character is detected, that is, it corresponds to step S8 in FIG.
Performs Cn detection processing. Here, for example, when the first column address of the black data of the second character “I” or “Ma” in FIG. 6 is detected as C ₂ , this column address counter value C ₂ is determined by the gate in step C 3. It is sent to the coincidence determination calculation unit 68 via G3. Then, the process proceeds to step C4, the consistency determination computing section 68, the seventh in step S5 of Figure fetches the column address C ₁ indicating the leftmost first character previously stored in the address data memory 67, the column address subtracting the column address Cn indicating the leftmost n th character given above Figure 10 step C3 from C _1. That is, in this case, the leftmost column address C ₂ of the second character is subtracted from the reference column address C ₁ , and the result of this subtraction is the corresponding character, in this case, the deviation width of the second character. Dmn and stored in the address data memory 67 in step C5. Here, for example, in step C4, when the reference column address C ₁ and the column address Cn of another character are equal, the corresponding character shift width Dmn =
The coincidence determination signal is output as 0 to the control unit 51 and the address data memory 67. The processing of steps C4 and C5 in FIG. 10 is the same as steps S9 and S10 in FIG.
It corresponds to the processing of.

In this way, when the detection and storage of the deviation width Dmn of the second character is completed, "1" is added to n indicating the number of characters in the same character string in step S11, and again through the processing of steps S7 to S10, in this case 3 The deviation width Dmn of the th character (“J” or “or” in FIG. 6) is detected and stored.

Thus, the deviation width for all characters in the first character string
When the Dmn detection processing ends, the process proceeds to step S12, and "1" is added to m indicating the number of character strings. This allows Dmn
Is changed to the next character string, that is, the second character string in this case, and by repeating the above steps S3 to S12 again, all characters in all character strings in the first image data memory 60 are detected. The shift width of is sequentially stored in the address data memory 67.

After that, the process proceeds to step S13, and the first image data memory 6
All the read character data stored at 0 are sequentially transferred from the first character of the first character string to the second image data memory 60a, and at the same time, the shift width Dmn of the column address corresponding to each transfer character is set to the address. Retrieved from data memory 67,
The second address counter 61a is sequentially set. Thereby, the first image data memory 60 to the second image data memory
The memory address of the image data input to 60a is the second
It is sequentially corrected by the corresponding shift width Dmn via the address selector 62a, and each character data is stored in a state in which the column address is aligned with the character existing at the leftmost end of the same character string.

Next, the operation when printing out the image data read from the original B as described above will be described. When printing out image data,
The read / print switch 4 is switched to the print position. The power supply / read / print changeover switch 4 is switched to enter the print mode, and the control unit 51 uses the select signals d and e to select the data selector 59 and the address selector 62.
To the control unit 51 side. In this state, as shown in FIG. 1 of the user, the print section 3 in the head section HA is printed on the printing paper A.
, And the handy copy machine body 1 is moved in the direction of the arrow X in the figure while pressing the operation keys 5a and 5b. The rubber rollers 25a and 25b rotate with the movement of the main body 1 of the handy copying machine, and the rotation is transmitted to the gear 28 via the gears 26 and 27. Then, the encoder disk 34 rotates in accordance with the rotation of the gear 28, and the movement amount detection signal is taken out from the photosensor 37 in accordance with the movement speed of the handy copy machine main body 1 as in the above reading.

The rotation of the gear 28 is transmitted to the constant velocity feed roller 23 via the one-way clutch 33, and further to the take-up roll 24 via the gears 29 and 30. As a result, the constant-speed feed roller 23 and the take-up roll 24 rotate, and the shaft 31, ink ribbon guide passes from the ink ribbon roll 22 through the slit 43 of the step D, the heat generating portion 21a of the thermal head 21, the ink ribbon guide window 42. 44. The ink ribbon 22a guided by the constant velocity feed roller 23 is wound up. In this case, the constant velocity feed roller 23 is adjusted to the movement amount of the handy copy machine body 1 so that the relative speed is not generated between the printing paper A and the ink ribbon 22a as the handy copy machine body 1 moves. Rotate.

On the other hand, the movement amount detection signal output from the photo sensor 37 is sent to the control unit 51, the timing signal generation unit 52, and the speed detection unit 53 as the output signal of the encoder 39 as described above. The timing signal generation unit 52 is a control unit according to the movement amount detection signal sent from the encoder 39.
A one-line print command is output to 51 and a print timing signal is output to the thermal head drive circuit 64. Further, the control unit 51 sequentially designates the row and column addresses of the first image data memory 60 according to the movement amount detection signal from the encoder 39, and selects the image data stored in the first image data memory 60 as a data selector. The data is read out via 59 and is output to the thermal head drive circuit 64 row by row. Further, when the timing signal generator 52 gives a one-line print command, the controller 51 adjusts the number of black characters in the print data, the head temperature from the temperature sensor 55, the voltage detection signal of the power supply voltage detector, and the density adjustment volume 7. The energization time for the thermal head 21 is set based on the value and the like, and the image data read from the first image data memory 60 is output to the thermal head drive circuit 64. The thermal head drive circuit 64 drives the thermal head 21 according to the control data from the controller 51 and the timing signal from the timing signal generator 52. This thermal head
By driving 21, the image data is thermally transferred onto the printing paper A via the ink ribbon 22a. In this case, the unused part of the ink ribbon 22a is sent out from the ink ribbon roll 22 as the handy copy machine body 1 moves, and the used part after being printed by the thermal head 21 becomes the ink ribbon take-up roll 24. It is wound up one by one. By moving the handy copy machine main body 1 as described above, the image data stored in the first image data memory 60 is sequentially printed on the printing paper A.

When the correction switch 7a is operated when the image data read from the surface B of the original is printed out, the same print processing operation as the above is stored in the second image data memory 60a. This is performed for image data. For example, when the read image data is character string data, the copying machine main body 1 at the time of reading operation is performed.
The character string read by curving due to the leftward and rightward deviation of the character is printed on the printing paper A in a state of being straightened.

Therefore, according to the handy copy machine having the above configuration,
For example, when the character string data on the document surface is read, after the reading, the correction switch 7a is operated to temporarily change the image data recorded in the first image data memory 60 in the read scanning state to each character. Since the curvature of the character string is corrected by address and transferred to the second image data memory 60a for each column, the image data stored in the second image data memory 60a can be stored during the printer processing of the read image data. By reading and printing, it becomes possible to print the image data, which is read by bending to the left and right during the manual reading scan, with the character string corrected.

As described above, according to the present invention, an image sequence consisting of a plurality of images sequentially read by the image sequence reading means according to the movement of the apparatus main body is sequentially displayed while maintaining the overall shape of the image sequence. One image sequence storage means, and the width in the width direction orthogonal to the column direction of the image sequence stored in the first image sequence storage means is detected by the width detection means, and the first image sequence storage is performed. The image width in the width direction of each of the images forming the image sequence stored in the means is detected by the image width detecting means, and the image width in the width direction of each of the images detected by the image width detecting means is detected. Based on the width in the width direction of the image sequence detected by the width detection unit, the displacement detection unit detects the displacement of each image forming the image sequence stored in the first image sequence storage unit. However, this deviation detection means Based on the detected deviation of each image
The image sequence stored in the image sequence storage means is corrected for each image, and the corrected image sequence is sequentially printed in accordance with the movement of the apparatus main body. It is possible to provide an image data processing device capable of correcting the deviation of the character string in the left-right direction for each character and printing it even if the line is irregularly bent left and right.
