Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device, and relates to display control on a display unit at the start of printing, during printing, and at that time.

[Prior art]

Conventionally, in such devices, typewriters and the like have already used batch printing, line-by-line, character-by-character, etc. as printing methods. By the way, there is also a device that starts printing when a print start input is received, which is called sequential printing. This device has a sequential printing mode, and when the line feed key is pressed in that mode, the characters input before the line feed key is input are printed.

That is, when the line feed key is pressed after inputting the text shown in FIG. 1(a), characters 1a to 1b are printed. Furthermore, the first
Assume that a sentence is input as shown in Figure (b). Here, 18 is a mark indicating a line feed input using the line feed key. Then, when the line feed key is pressed, characters from IC to 1d are printed.

However, this device prints characters after the characters that have already been printed, but the operator cannot tell how far the print has been made other than by looking at the printout. The problem with this method was that it was difficult to tell how far it had been printed.

[Problems to be Solved by the Invention] The present invention was made in view of the shortcomings of the prior art mentioned above.The purpose of the present invention is to clearly indicate how much printing has been done, and to clarify the data based on the usage. The purpose is to make it easier to modify and edit.

[Failure to solve the problem]

As a means for solving this problem, for example, the configuration shown in FIG. 2 is adopted, in which 2a is a CPU, 2b is a storage device, 2c is an input device, 2d is a printing device, and 2e is a display device.

[For production]

In the configuration shown in FIG. 2, the character processing device of the embodiment stores a print start code in the storage device e2b, and
By displaying a print start mark on the display device 2e, the operator is informed of the start of the next print.

〔Example〕

The present invention will be explained below with reference to one example.

FIG. 2 is a block diagram of this embodiment. A CPU 2a controls the device. 2b is a storage device, which includes a program to be controlled by the CPU, a text file that stores character information input from the input device 2c, a CG that stores character fonts used in the printing device 2d, and the display device 2e, and CP02a.
It consists of work areas used for processing. This work area contains batch print/sequential print mode register I.
Have TR.

2C is an input device, which is a keyboard in this embodiment. 2d
is a printing device that performs printing using the CG in which the character font in 2b is stored.

4e displays a part of the document file on a display device.

! ! FIG. 83 is a diagram of a keyboard which is an input device Eta 2 c. 3a is a group of keys for inputting characters. 3b is a key that triggers the start of sequential printing when in sequential printing mode;
At other times, it is the normal newline key. 3c is a batch sequential mode switching key. When this key is pressed when not in sequential printing mode (hereinafter referred to as batch printing mode), pressing this key will switch to sequential printing mode, and when in sequential printing mode, pressing this key will switch to batch printing mode. be. In other words, the storage device 2
The contents of the batch printing/sequential printing mode register ITR in b are changed by pressing this key. If k ITR in batch printing mode is set to 1 when in O1 sequential printing mode, if the batch sequential switching key 30 is pressed when ITR is O, ITR becomes 1 and changes to sequential printing mode.
When the batch sequential switching key 30 is pressed when the ITR is 1, the ITR becomes O and the batch printing mode is entered.

FIG. 4 shows a font that is displayed on the first display device 2e when the sequential printing start key 3b is pressed in the sequential printing mode, and is stored in advance in the CG in the storage device. For example, Figure 1 (
If the sequential print start key 3b is pressed while the text shown in a) is being input, the fifth
As shown in FIG. 4(a), the font shown in FIG. 4 is displayed, indicating the position and location to be printed next. And of course the fifth
The characters 5a to 5b shown in figure (a) are printed by the printing device 2.
Printed by d. 5C is a cursor indicating the next input position.

Now, in the state shown in FIG. 5(a), the text file in the storage device 2b is as shown in FIG. 6. In the text file, each character is stored with a unique code corresponding to it, but for simplicity, the characters and symbols are expressed as they are in Figure 6.

Next, after inputting as shown in Figure 1(a), and then inputting text as shown in Figure 1(b), (Figure 1 is a diagram for explaining input and shows the form of printing or display. It's not,
), the display will be as shown in FIG. 5(b). When the line feed key 3b is pressed here, characters 5d to 5e are printed, and the font 5f disappears from here, as shown in Figure 5 (C
) The font shown in FIG. 4 is displayed at the 5g position. This is when the previous print start mark disappears.
If it does not disappear, print start marks 5h and 51 are displayed as shown in FIG. 5(a).

This can go either way. In the state shown in FIG. 5(b), the operator knows that since the sequential printing start mark shown in FIG. 4 is at position 5f, the next time he presses the line feed key, characters starting from 5d will be printed.

FIG. 7(a) shows a control flowchart for the above-mentioned display. Perform key manpower in step 7a. After that, the input key is determined. In step 7b, it is determined whether the 30 batch sequential switching keys have been pressed. If it is not pressed down, go to step 7f. If the 3C key is pressed in step 7b, jump to step 7C,
Determine whether TR is O. If ITR is O (batch print mode), the process jumps to step 7d, and if ITR is l (sequential print mode), the process jumps to step 7C. In step 7d, ITR is set to 1, and in step 7C, ITR is set to O. After that, return to A and wait for key personnel again. In step 7f, it is determined whether the line feed key has been pressed. If it has not been pressed, the process goes to step 7g and other processing is performed. Here key 3b
, 3c is pressed. If the key 3b is pressed, the process jumps to step 7h and checks the contents of the register ITR one after another. If it is 1 (sequential printing mode), the process jumps to step 7j, and if it is 0, the process jumps to step 71. I
When TR is O, it is batch printing mode, so line feed processing is performed up to 7. If ITR is 1, it is sequential printing mode, so 75
Then, search for the print start mark closest to the current cursor position and before the current cursor position on the text file. If there is no print start mark in the text file at this time, the process goes to step 7 and the printer 2d prints from the first character of the text file to the character at the current cursor. If there is a print start mark, the printing device 2d prints the next character up to the current cursor position. and step 7
h. After finishing the printing process of 7 sentences, jump to 7m.

7m stores a line feed and a mark indicating the start of printing at the current cursor position in the text file. Then move the cursor position to +
Do 2. After that, return to A and wait for key personnel.

To delete the previous print start mark, it is sufficient to perform the process 7n shown in FIG. 7(b) before 7m.

At step 7n, the previous print start mark is deleted.

Then it flies to 7m.

Although the cursor position is not explained in the flowcharts shown in FIGS. 7(a) and 7(b), it can be easily realized by providing a register for storing the current cursor position in the work area in the storage device. Furthermore, the process of searching for a print start mark can be carried out by searching the text file forward from the character at the current cursor position and searching for the first print start mark found. The printing method itself by the printing device 2d is not the gist of the invention, so a description thereof will be omitted.

Furthermore, although the print start mark was searched for in step 7j of the flowchart of FIG. By storing the position in IKRB, when a print start trigger is input in sequential print mode, the current cursor position address and I
You can easily calculate the position of the nearest print start mark smaller than the current cursor position address in KRB, and if you want to delete the previous print start mark, use IKRB.
The printing start mark position can be easily found during the process of step 7n in FIG. 7(a) by referring to , so that the process can be completed quickly. Also, in this case, ITRB only needs one storage area.

〔effect〕

As explained above, according to the present invention, the operator can see the print start mark, so the operator can now understand where to start printing when sequential printing is performed. In addition, since it is possible to correct the printed text and then reprint it, it is possible to confirm the corrected text before officially printing, making it possible to provide a character processing device with high operational efficiency.
