PURPOSE:To enable to print a continuous underline at a high speed, by providing a means for controlling printing of an underline when a carriage is moved horizontally, in a printer capable of printing an underline. CONSTITUTION:According to printing data (a) transferred from the side of a host system or the like, a printer-controlling part A controls a printing mechanism part C through a printing-controlling part B to print a desired character. When printing data designating printing of an underline are inputted, an underline printing controlling means D functions to print an underline through the printing-controlling part B and the printing mechanism part C in accordance with the designation of the horizontal movement in the printing direction of a carriage for the printing mechanism part C. Accordingly, by printing the underline at the time of the horizontal movement for printing, the underline can be printed also at spaces, if any, between characters. In addition, it is unnecessary to move the carriage twice for the same line, and it is possible to print at high speed.

Description

DETAILED DESCRIPTION OF THE INVENTION Whale 184 (Jju!F) This invention relates to a printer capable of printing Anglines.

Conventionally, there is a printer that prints out the Angline by printing it twice, for example, at the same position as the character that says Angline.

However, when printing an underground line in this way, if there is a space (blank) between characters, the position of that space will not be the printing position, that is, the carriage will not stop, so the underground line will not be printed. There is an inconvenience that it is not possible to print, and continuous angle lines cannot be printed.

Therefore, some printers are designed to print an unlined line at a necessary location on the line while moving the carriage in the horizontal direction (pack space operation) to return the carriage to the beginning of the line after completing printing for one line.

However, when printing underground lines in this manner, the problem arises that the carriage must be moved twice for the same line, which slows down the printing speed.

This invention has been made in view of the above-mentioned points, and its purpose is to enable printing of continuous angle lines at high speed.

Purchasing Q (9 days □ mackerel) Hereinafter, the configuration of the present invention will be explained based on one embodiment.

When the printer 1-data that instructs the printing of the Angline is manually inputted, the printer 1-data that specifies the horizontal movement of the carriage of the printing mechanism section C in the printing direction is used. Then, the printing mechanism section C is controlled via the printing control section I3 to print an Angline.

In this way, by printing an angline on the horizontally moving piece (space movement) 114'' of the carriage for printing, even if there is a space between characters, the angline can be printed in that part. In addition, since there is no need to move the carriage twice for the same line, high-speed printing is possible.

Additionally, the horizontal movement of the carriage in the printing direction +1

The main controller 1 and the roll circuit 4 are constructed by a microcomputer.

FIG. 6 is a block diagram showing an example of an underground print control circuit that constitutes the printer control circuit 41 of FIG. 5.

In the figure, the data discrimination circuit 55 determines whether the print data from the data buffer 42 in FIG.
If it is the underline start data US and the underline end data UE, the data PD to the printer 1 is sent to the underline mote setting circuit 56 j1.

Further, this data discrimination circuit 55 is connected to the data buffer 42.
pudding 1-data P D is character data C L)
and space (blank) data SI) then transfers the print I-data PD to the space amount determination circuit 57.

The underline mode setting circuit 56 includes the data discrimination circuit 5
During the period from the time when the underground line start data 1S is inputted through 5 to the time when the underground line end data tJE is input, the unline dry setting data UD is input to the space delay and discrimination circuit 57. Output.

The space discrimination circuit 57 selects the character data CI') and the space data SD transferred from the data discrimination circuit 55.
The space motion surface (horizontal movement claw of the carriage) corresponding to the space motion surface (horizontal movement claw of the carriage) is determined, and the space motion surface data SDD, which is the result of this determination, is input to the underground mode setting data UD from the underline mode setting circuit 56 or manually. When the number of times of printing is present, the number of printing times judgment circuit outputs it on the fifth day.

The underline size memory 58 stores 115 pieces of angline width size data US which also indicates the width size of angline type or angline type (for example, minus "-" type).

As shown in FIG. 7, the Antaline 4-8 width size is set to 1 width + 3, which is 1 width shorter than the physical width f) of the typeface A. This is 4! This is because if the physical width is 1 x 8, the line may be cut due to hunting etc.1.

On the 5th day of the printing count judgment circuit, the space movement amount data S I) l) from the space 11 judgment circuit 57 and the underline size memory 58 contain the space operation amount data S I) 1) and the underline size memory 58.

As 1 printing space amount setting circuit 60 and printing number aI
It is transferred to the number path 61.

The 1 printing space setting circuit 60 keeps the count value C of the printing number 11 number circuit 61 until the count value CN of the printing number 11 number circuit 61 becomes "0".
Every time N is r-N, Angline 4 yellow width size data USD from Angline size memory 58 is output as 1 printing space operation data SPD, and the number of printing times 1 number circuit 61 becomes "0". When the print count is 11, data indicating the final space operation Mrn from the print count data l) F]) from the print count 11 number V359 is output as one print space operation amount data SPD.

Incidentally, when it is necessary to print underline (underline mode), this one printing space operation amount data SPD is outputted as data 18 to the printer interface circuit 44 in FIG. 5.

The printing number counting circuit 61 uses data indicating the regular space operation star number 1) of the printing number data PFI) from the printing number judgment circuit 5th as the initial value of the 31 numerical value CN, and Each time the print end signal 1''E from the printer interface circuit 44 in FIG. 5 is input manually, the count value CN is decremented by j~(-1).

In addition, this printing number HI number path 61 is connected to the normal space operation amount number n force reward [numerical value CN etc.] from the time when the counted value CN becomes rOJ and then the printing end signal PE.
Until Goo 1- close signal GC is input, Goo 1-

In this case, there is no Angline type, and the analogy is minus r-
When changing the position of the J type to make it an angle line,
This process is performed by a roll 43 to the main controller 1.

Note that the printer control circuit 41, including the underline printing control circuit, is configured by a microcomputer.

Next, the embodiment A18 of the embodiment configured as described above will be explained with reference to FIG. 8 and subsequent figures.

Figure 8 shows the printer control circuit shown in Figure 5.
/ FIG. 2 is a flowchart showing an example of a line printing control operation.

To briefly explain this operation, when a space (Sl) operation is required, the printer control circuit 41 first determines whether or not it is in the underground mode, and then selects the underground mode.
-dana (difference is t'j; Knee CS 'z Process to appear.

On the other hand, in the underline mode, the space movement amount/underline width size is determined based on the space movement amount and the underline width size, which correspond to the required carriage movement amount. Then, underground r.
Number of space movements in the horizontal width size (regular number of space movements) Calculate 3 For example, as shown in Figures 9 (a) to (c), assuming that the required space movement amount is [) 1. Anta line 4. fl I width size is D B, I / I -) As a result of the operation tγ of II, DI/DB=3·−ml. As a result, the normal space operation amount number 11 is ++−3, and the final space operation amount III becomes m ″ m.

After that, it is determined whether the regular space movement amount is 11 or 0, and if the judgment result is n=o 4L, the space movement amount of the angle width size is output as data DA, and the carriage A strobe signal C8 is output to cause the main controller 1 to control the roll circuit 43 to move the carriage 21 in the horizontal direction by the angle width size.

Then, it outputs the data DA for selecting the Angline type, and also outputs the lobe signal P to the PrintVoice 1.
S is outputted to cause the roll circuit 43 of the main controller 1 to perform Angline printing control.

After that, the regular space operation star number 11 is decremented by 1
-(-1) and returns to the process of determining whether it is 11-0 or not.

For this, if the determination result is rr = O, it is determined whether the final space movement amount 111 is m =: O,
If the result of this determination is m = 0, the process ends.

If the determination result is not m=o, the final space motion im is output as data DA, and the lobe signal C8 is output to the carriage 1, so that the main controller 1-roll circuit 46 moves the carriage 21 to the final space motion fi. control to move it in the horizontal direction.

Thereafter, data DS for selecting Angline type is output, and pudding 1 to Boyles I-Loeb letter M,
PS is output to cause the main controller 1 to the roll circuit 43 to control printing of Angline.

Thus, for example, as in the example above, TI = 3
.

If m = Tn 1, the position P as shown in FIG. 9(d). From angline width size D + 3 spaces (place 11PI) + underline printing → angline width size 1 B space (position 1] 2), underline printing → underline width S, rz D + 3 spaces (place 1iRPa) The following operation is performed: r underline printing→final space movement amount H1l space (position P4) l underline printing, whereby an underline is printed as shown in FIG. 4(E).

By performing such control, for example, the print data PD can be changed to, for example, rabc, dcf ghi
k1mn OPq ■ rsJ (@: Angline start code, ■: Unline end code 1-), the print result is rabc def gh i -j- (↓rn
It becomes n o p q r s J.

It should be noted that after the Angline start code @ is input, the Angline end code (■) is input and the Angline continues to be printed even if the line breaks (see FIG. 10).

In this way, this printer prints the anglines when the carriage moves horizontally in the printing direction, so even if there is a space (blank) between characters, the anglines are printed continuously. In addition, since there is no need to move the carriage horizontally twice for the same line, the printing speed does not decrease.

EFFECTS As described above, according to the present invention, continuous angle lines can be printed at high speed.
