Abstract

PURPOSE:To print or display a form wherein characters are mixed by mixing noncharacter information such as ruled-line information with character pattern information from a character pattern memory. CONSTITUTION:This describes a pattern generating function for a form of a document, etc., which is printed or displayed simultaneously with character data. Character information in form information is inputted from a host device by a character code showing one of characters and position information on where the character is to be printed, and noncharacter information in the form information is inputted in the form of compressed data, etc. In output operation, a character pattern is read out of the character pattern memory 3 in a printer or display device and during the decoding abd output of said noncharacter information, the character pattern is inserted at a specified position on a printing or display surface, thus printing or displaying a character-mixed form.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printer or display device that displays characters, lines, graphs, etc. 1 using dots, and particularly relates to a pattern generation function for forms such as book charts that are printed or displayed simultaneously with character data. It is.

Conventionally, simultaneous printing of forms and data as shown in Fig. 1 (&) is possible by printing form information including title characters as shown in Fig. 1 (b), data information shown in Fig. 1 (C), and all printers. Alternatively, the images are logically superimposed and output in a device such as a display. According to this method, in a high-speed printer such as a laser printer, the amount of character codes and dot strings transferred is doubled, and the printer control section requires a large amount of hardware to realize high-speed processing.

In other conventional methods, the form information in FIG. 1(b) is
All the lines and characters are developed in advance into dot information on a computer, and then the dot information is fully compressed and stored in an external storage device, etc., and the compressed data is transferred to the form memory of the printer section when printing. At the time of printing, the data information and the output of the form memory are logically combined and the data and i-me are printed simultaneously. According to this method, creating form data requires a large amount of program and computer processing time, and the character information contained in the form
Generally, the compression rate is poor, so a large capacity form memory is required in the printer section.

In the present invention, form printing with mixed characters is realized by combining non-text information such as ruler line information with character pattern information generated by fully utilizing the character pattern memory in the printer device in the printer section. . That is, the character information included in the form information is input from the host device as a character code indicating which character it is and position information indicating the position where the character is to be printed, and the non-character information in the form information is
When inputting compressed encoded data, etc., and outputting it to the output display screen, the character pattern is read from the character pattern memory in the printer or display device,
When the non-character information is decoded and output, a form containing characters is displayed or printed by inserting the entire character pattern at a designated position on the display surface.

By simplifying the creation of form data and handling all code information of characters such as kanji, which have poor data compression rate, contained in 7-ohm data, the required hardware performance is reduced, and the hardware is also downsized. All can be realized. Next, the present invention will be described in detail with reference to the drawings showing one embodiment of the present invention.

Referring to FIG. 2, one embodiment of the present invention receives a code from a host device and converts it into dot string information by using a page buffer 1 to store the code and the character code output from the page buffer 1 by using the character pattern memory 3. a printer control unit consisting of a dot conversion unit 2 that performs printing; a form synthesis control unit 4 that develops form information from a host device into a character insertion control memory 5 and a form buffer 6; a selective decoding circuit 7 for controlling decoding;
It includes an OR circuit 8 that logically ORs the dot strings of each of the character information and form information.

Next, the entire operation of this embodiment will be explained using FIGS. 2 and 3. The form information input from the host device is the third
As shown in the figure, it is composed of an insertion character code indicating the character to be inserted into the form, character insertion position information indicating the position where the character should be printed, and compressed dot image data other than characters. The form synthesis processing section 8 stores the corresponding character pattern from the character pattern memory 3 into the form buffer 6 using the inserted character code according to the form information shown in FIG.

Next, the form synthesis processing unit 8 marks the position in the character insertion control table 5 at which the character pattern should be inserted based on the character insertion position information. The form synthesis processing unit 8 performs all of the above processing for the number of characters to be inserted for the insertion character code and character insertion position information in the form information, and stores the subsequent image data continuously after the character pattern in the form buffer is stored. do.

FIG. 4 shows the structure of the character insertion control table.

Figure 4(a) shows the X direction (line direction) of the character control table.
This indicates the insertion character position, where 1 box indicates 1 bit, and 1 column displays 1 line of characters. Therefore, in the case of this fifth embodiment, the number of inserted character lines must be n lines or less.

FIG. 4(b) shows the vertical position where the inserted character exists, and similarly, one square is stored as one bit. Therefore, the inserted character is printed so that the unmarked intersection of (,) and (b) in FIG. 4 is at the upper left of the character. Also, in the form buffer, the character pattern is in the order of transfer of the dot string to the printer unit, that is, Y is L name 4...X is L23. They are stored so that they are output in the order of...

When printing, the contents of the form buffer are read out in synchronization with the data output from the dot conversion section 2, and when there is no instruction from the character insertion control table, the image data area of the form buffer is read out and the selected decoding circuit 7
The compressed image data is decoded and input to the OR circuit 8, and when there is an instruction from the character control table, the selection decoding circuit 7 reads out the character pattern area sound in the form buffer and inputs it to the required dot. It is converted into a column and inputted to the OR circuit 8. As described above, the OR circuit 8 performs the logical sum of the dot pattern 6 line of character information from the dot conversion section and the dot pattern string of form information, and transfers the result to the printer section for printing.

As explained above, the present invention simplifies the creation of forms by synthesizing character patterns included in form information based on character insertion position information within a control device of a printer or display. It was planned to
