10 is a form pattern set management RAM for storing information regarding the available form pattern sets (described later), and 214 is a CPU board.

Next, the operation of the circuit shown in FIG. 2 will be explained in detail. The circuit shown in FIG. 2 outputs a predetermined form pattern using a control command sent from a host computer or a moving switch (not shown), and this form pattern is output together with a character pattern. By the way, the form pattern set mentioned in +iii is a set of data for outputting the form as shown in FIG.
4I+1 Female System 1 Trowel Form Pattern Generator 205 (memory such as RAM or ROM) as shown in Figure 3
is stored in. Therefore, in order to output a plurality of types of form patterns, it is sufficient to have a plurality of form pattern sets in the form pattern generator 205.

The form pattern set consists of a form pattern set identifier 301 for identifying the type of form and a form information section 328, and the form information section includes a 'J1 line section 30.
2. Consists of a logo section 310, a character section 31a, etc. Also,

F line attack 304, starting position 11' of each ruled line? 306
End-r position iii 307 and name information indicating the thickness 308 of each ruled line are stored. Similarly, the logo section 310
is the logo information section 311. This logo information section 3
11 is the low 1' G312, the 11) inclusive start position of each logo 314, the shout of each logo 1315, the height of each logo 316
Information indicating the logo and the actual logo pattern 317 are stored.

The character section 318 also has a character information section 319, which contains 320 character sets (referring to one or more groups of characters) used in one form, and each Character pattern set identification r-address of character set (address for specifying the set of each character set) 322, number of characters in each character set 323,
Information indicating a writing start position 324 of each character set and a character code 325 are stored.

The CPU 203 monitors the attachment/detachment of the form pattern generator 205 using the attachment/detachment signal V+211, and rewrites the contents of the form pattern set management RAM 210 each time the form pattern generator 205 is attached or detached. Form pattern set jR management RAM2
The form pattern set management table in 10 has a structure as shown in FIG.

401 is an identifier for identifying a form pattern set that can be used (U), and is the form pattern set 7 shown in FIG.
This is similar to the set identifier 301. 402 is the start address of the form pattern cell I, and 403 is the size of the l form pattern set. The form pattern set identification 'E, form pattern set start address, and form pattern set size are provided respectively for one (1) ohm.If there are many types of forms that can be used, H The following three types of data are stored. When the CPU 203 receives a form pattern set change command from the host computer 201, it refers to the rough form pattern set management table written in iQ, changes the address of the form pattern set, and selects the form to be used.

Next, the form pattern generation method in this embodiment will be explained in detail using the flowcharts shown in FIGS. 2, ff13, 5, and ft5B. The flowchart shown in FIG. f7's6 is programmed and stored in the ROM in the CPU 203, for example.

Note that a well-known method can be used to generate the character pattern, so a detailed explanation will be omitted here.

When control commands (form selection command and form output command) and print data are sent from the host computer 201 via the input buffer 202, the CPU 203
sends print data (character code) to the character generator 204 to generate a character pattern, and also generates a form pattern, which is stored in the output page buffer.

As shown in Figure 3, the form is ruled lines.

Consists of logo and letters. Therefore, the CPU 203 identifies the ruled lines 302, logo 310, and characters 318 in steps 601, 602, and 603, and operates accordingly. Termination r is performed upon recognition of the end identification /-326. First, for the J'r line, in step 610:
J'l! Line 3 304 is the counter 1 in the CPU 203.
Put it in.

Next, in step 611, 'J'r t%I start position 30
The current position (address occupied by the dot) is advanced to the position shown in 6 (see FIGS. 3 and 5).

After that, in step 612, thickness information 308 (number of dots)
While advancing the current position according to the dots, dots are generated up to the position indicated by the ruled line end-r position 307 and sent to the output page reference 207.

In step 613, the counter 1 is decremented, and in step 614
At step r1, it is determined whether all the ruled lines have been written. If not, the process moves to step 611, and if it has finished, the process returns to step 601. Also, step 602
If it is recognized as a logo in step 620, the number of logos 312 is set in the counter I, and in step 621 the position indicated by the logo start position 314 (see FIGS. 3 and 5).
Move the current position (address including the dot J!) to . Then, in step 622, the height information 316 is sent to the CPU 2.
Set it to counter 2 in 03.

Next, in step 623, the width h'i information 315 is sent to the width h'i information 315 (then, one width pattern from the logo pattern 317 is sent to the output page buffer 207, and in step 624, the counter 2 is totaled and the height information is 1). r11 determines whether or not the 316-minute logo pattern has been sent (step 625).If it is not finished here, the process returns to step 623.If it is finished, the 10-minute logo pattern is sent to the output page 9 buffer 207, so , the counter l is counted as #, and it is determined in step 627 whether or not there is the next logo.If there is still a logo to be sent to the page buffer, the process returns to step 621; otherwise, the process returns to step 601. If it is determined in step 603 that it is a character, step 6
At 30, enter the number of character sets into counter 1. Next, in step 631, select the necessary heavy body J 4Ji! At the same time, the number of characters 323 is entered into counter 2 at step 632. Thereafter, in step 633, the current position (dot write address) is moved to the position indicated by character position 324 (see FIGS. 3 and 5). Next, in step 634, the character code is sent to the character generator 204 to generate a predetermined character pattern and stored in the output page buffer, and at the same time, in step 635, the counter 2 is subtracted. and step 63
At step 6, it is determined whether character patterns have been output for the number of characters stored in the counter. If the process has not ended, the process proceeds to step 633, and if it has, the count is decremented by 1, and in step 638 it is determined whether there is another character set to be output. If there are still character sets to output, return to step 631 iii+
The same operation as described above is performed, and when the output of all character sets is completed, the process returns to step 601.

In this way, ruled lines, logos, and characters are generated, a form is written on the output page, and a printing operation is executed.
