Abstract

PURPOSE:To print page numbers through a simple construction even at the time of printing through rotation, by counting the separations of a detected printing page, then rotating a character font for a page number based on the counted numerical value in the same direction as that for printing document information through rotation, and printing the page number. CONSTITUTION:A register SG stores a number corresponding to the number of characters in one line in a code buffer 71, and a register PNG stores about one half of the content of the register SG. When the content of the register SG is an odd number, {(SG+1)divided by 2} is calculated, and the result is stored into the register PNG. For example, when the number SG of characters in one line in the code buffer 71 is 9, the 5th line in printing through rotation is the line in which a page number is to be printed. When the content of the register SG is an even number, {SGdivided by 2+1} is calculated, then the result is stored into the register PNG, and a flag PNF is set to 1. For example, when the number SG of characters in one line in the code buffer 71 is 10, the 6th line in printing through rotation is the line in which the page number is to be printed. Thus, in each of the cases, the page number is printed at a substantially central position of a character string printed through rotation.

It includes character codes and control codes. Here 1
The number of line format digits is 40, and the document information is edited in the line direction.

FIG. 2 is a flowchart showing the rotational printing control procedure of the embodiment.

<Description of registers and counters> In the figure, SG is a register that holds a number equivalent to the number of characters in one line of code buffer 1, and unless specified from the format setting key 33, the number of characters in one line or If specified, the specified number is retained. PNG is a register that holds approximately half of the contents of SG, and holds the line number on which the page number is to be printed in rotation. SPN is a register that holds the page number desired to be added to the first page of rotation printing, and holds the first page if there is no designation from the format setting key 33, and the designated page if there is a designation. Furthermore, P.N.
P is an odd-even flag, PN is a counter that updates and holds the page number of rotation printing, M is a page counter that points to the absolute page in the text, and N is a counter that counts the characters in the text in the column direction.

(Determining the line number where the page number should be printed) In step S1, it is determined whether the contents of SG are an odd number. If it is an odd number, in step S3, ((SG+1)÷2) is calculated, and the resulting value is converted into PNG. Store in.

For example, if the number of characters SG in one line of the code buffer 71 is 9, the fifth line of rotation printing is the line number at which the page number should be printed. Also, when SG is an even number, in step S2 (SG÷2+1
), store the resulting value in PNG, and step S4
The flag PNP is set to 1. For example, if the number of characters SG in one line of the code buffer 71 is 10, the sixth line of rotation printing is the line number where the page number is to be printed. In this way, in any of the above cases, the page number is stamped at approximately the center position of the rotationally printed character string.

(Rotate printing of document information) In step S5, the contents of the specified SPN or 1 is transferred to the counter PN.In step S6, the page in the text on which rotation printing is to be started is set in the page counter M, and in step S7, 1 is transferred to the counter N. In step S8, from the page indicated by the counter M page in the text, the character code of the Nth column (initially the first column) is set from the last line of the Mth page to 1 as shown in FIG. The characters are read one by one and rotated and expanded to the first line of the image buffer 72. At this time, it is considered to leave a character pitch corresponding to the normal line pitch. In step S9, the printer 5 is driven. ,
The developed pattern data for one line is sent to the thermal head 51.

In step S10, it is determined whether the contents of counter N and SK match or not. If No, counter N is incremented by 1 in step S11. In step S12, it is determined whether the contents of the counter N match the contents of PNG. If No, the paper is fed at the line pitch P in step S13. This line pitch P is narrow considering the normal character pitch.

The flow returns to step S7 to perform rotational line printing of the next column of document information.

<Rotational printing of page numbers>' If the content of the counter N matches the content of PNG in step S12, the main unit determines whether the flag PNF is 1 in step S20. The problem with PNP=1 is when the number is even. In step S21, the paper is fed by P/2 pitch, in step S22, the contents of PH are rotated and printed at almost the left end position of the paper, and in step S23, the paper is further fed by P/2 pitch. Feed the paper. This state is shown in FIG. 5(A).

Also, if it is not PNP-1, it is an odd number, and step S2
In step 4, page numbers are printed in rotation in the same manner as in step 322 above. This state is shown in FIG. 5(B).

<Page break or end> If the content of counter N and the content of SK match in step SIO, the paper is fed by P pitch in step S14, and it is determined in step S15 whether the counter M is the specified final page or not. do. If it is not the final page number, further step S1
In step S17, it is determined whether or not the print stop key is the print stop key, and if it is not the print stop key, the key wait state is entered in step S17. here,
A message to that effect is displayed on the display section 4, and the user is asked to decide whether to print the next page as well. Normally, the paper is replaced and the print resume key is pressed again, so step 51
Proceed to step 8 and add 1 to the contents of PN.

In step S19, the contents of M are incremented by 1 and the next page is printed in rotation.

Further, if the content of the page counter M matches the designated final page number in step S15, or if the print stop key is pressed in step 316, the process ends.

[Effects of the Invention] As described above, according to the present invention, it becomes possible to know the number of printed sheets and the order of the printed materials even during rotation printing, and in the future, memory capacity will continue to increase, the number of pages will increase, and the number of printed materials to be handled will increase. As the number is expected to increase, the effect is tremendous.

Furthermore, this makes it possible to provide the user with an easy-to-use document information processing device.
