(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides an electronic system that uses instructions using letters, numeric keys, copy keys, function keys, or a combination of two or more keys. It is used in electronic typewriters that print based on III@. Especially with this type of typewriter, when you want to print again while changing a part of the format that was actually printed, press the copy key.

This invention relates to an electronic typewriter having means capable of printing any number of times using a printed moss type.

[Conventional technology]

In recent years, all lines of printing have been done by electronic control, and a simple display device, especially an LCD, has been used to display, edit, and print one line or multiple lines, so that all five functions or one sentence can be created. Four types of electronic typewriters have been commercialized that have a printing function2, but it is impossible to judge whether or not the format matches the specified format until the actual printing is done after editing. The current situation is that it is difficult to create multiple copies in a certain format, for example by changing the name, location, etc. At present, printing must be performed repeatedly.

[Problem that the invention seeks to solve]

As shown above, with the conventional technology, even if you want to change only a part of a similar format, you must first edit the input data and then print, which is extremely inefficient.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide an electronic typewriter that allows only a portion of the print job to be changed during the printing operation.

[Means for solving problems]

The present invention provides a printing device that prints characters on paper based on character information input from a keyboard, and a code representing the character information input from the keyboard and the printing device ii+11# information, which is sequentially stored in the order in which they are input. means for causing the printing device to bank space with respect to the paper; and means for causing the printing device to bank space in response to a correction instruction signal from the keyboard and in an order opposite to that when the memory is in memory. An electronic typewriter having means for quickly converting the contents of the memory into spaces and erasing printed characters, and instructing to print the contents of the memory in the same format as the printed format. It is characterized by being equipped with a copy key and a function of printing in the same format as many times as desired according to the instruction.

[For production]

In the second aspect of the present invention, if a print stop control key is generated during text creation using a combination of the ¥f constant key, printing will be temporarily stopped at that point when the control key is recognized in the printing operation A. Interrupt and directly print character input from the keyboard.

〔Example〕

Figure 1 is. 1 shows a schematic configuration of an electronic typewriter according to the present invention.

The keyboard 1 includes various alphanumeric symbol keys 1a, a copy instruction key 1b, a function instruction key 1C, a space key 1d, and a shift key 1e.

Print erase key 1f and shift lock key 1g.

It is provided with a relocate key 1h and a paper movement key 11h.

The editing control unit 2 analyzes characters and control key input from the keyboard 1, and prints the instructions.
It has a built-in control program for displaying on the 11 section 3 and the display 4 and storing it in the memory 5, and the printing ftjll section 3 is used for the above-mentioned editing? The printing device 6
The printing mechanism 6a is driven to print, and the sensor mechanism 7
The state of the printing device 6 is detected based on the information from.

The status is transmitted to the editing control unit 2. The display device 4 is, for example, 1. It is a QD display device, which receives and receives printed character data from the Henketsu Part 2 and displays it.

The memory 5 consists of a pamphlet 5a of line sentences and a one-sentence storage buffer 5b, in which print data and control data input from the keyboard 1 are sequentially stored, and the contents are changed as necessary. Since the printing control section 3, the printing device 6, and the mechanism and technology for deleting and erasing printed characters are well-known technologies, a detailed explanation thereof will be omitted here.

The operation of the electronic typewriter constructed as described above will be briefly described below.

When character input data is sent from the keyboard 1 to the editing control section 2, the DA collection control section 2 sends the data to the printing control section 3 and sequentially stores it in the editing buffer of the memory 50. The print control section 3 causes the printing device fili 7 to perform a printing operation based on the received character data, and returns printing completion information a from the printing device 7 to the print control section 3.

Collection of essays iB++ Part 2, if the input data from the keyboard 1 is a character, the character data is printed in the editing buffer memory 5a for - lines while printing the characters one after another. However, when arranging -lines or receiving line feed, paper vertical movement, or similar control data from the keyboard, the character data that has been stored in the editing buffer up to that point is transferred to the text storage memory 5b. 1 The editing buffer 5a is cleared and stored again from the next character input.This is if corrections, f changes, or additions are made within one line by bank space or correction operations during line printing. , if it is within the line that is being printed, the correction operation is also performed in the editing buffer 5IIL, and the corrected sentence is stored in the sentence storage memory 5b.Correction by bank space or correction operation described here.

The above in the editorial pamphlet! 1! The editing of the text associated with the first work is a technology used in electronic typewriters with a self-help correction function that have already been commercialized, so the details will be omitted.

Now, the target sentence: t' is being input and printed.

There are many cases where it is desired to change the name, location, etc. when printing on the primary page. In this case, use a function key such as a formant generator (generating the print stop code ?bi++ # code by a specific key combination) to provide control data to temporarily stop printing when reprinting from keyboard 1. When the editing control unit 2 receives this control data, it stores the control data in the -line editing buffer, and the character input data from the 1st level is only printed, and is stored in the 1st editing buffer. No. When a function key such as a formant generator is pressed again or a line feed key is pressed, the edit?tr1111@1 section stores the subsequently input character data in the editing buffer 5a again using the control data. , print.

Next, the reprinting operation will be described below.

In the text storage buffer 5b, sentences similar to those already printed by the above-mentioned method are stored together with respective control codes, so it is only necessary to read them and perform the entire printing operation according to the character codes and control codes.

When a control code for the copy key 1a, which is a reprint instruction key, is sent from the keyboard 1, the editing III control section 2 sequentially inputs character data or r, r, etc. from the text storage buffer 5b.
1 Read the control code and print it as instruction data for printing operation based on character data, line feed, vertical S shift of printing paper, left/right movement of printing mechanism, etc.? ItIJ'#Sends to J unit 3. Here, when the editing control section 2 reads the control code of the formant generator mentioned above from the text storage buffer 5b, the editing control section 1 temporarily suspends reading from the text storage buffer 5b, and inputs character input data from the keyboard 1, Or wait for print control data.

Here, when a character is input from the keyboard 1, the editing control section 2 sends printing or print control to the print control section 3 according to the character data or print control data, and the print control section 3 follows the instruction.

The printing device 6 is caused to perform printing operation and printing control.

In other words, this operation is the same as the operation from inputting a series of characters to printing.

Now, when an instruction to terminate the format generator, such as a line feed instruction, is issued from the keyboard 1, the editing control unit 2
'f'i Text storage memo + 75 again Look at the continuation from b and repeat printing, 2, and print control until the text is finished. The end of a sentence is controlled by a pointer or the like managed by the editing control section 2.

〔Effect of the invention〕

As detailed above, the present invention is an electronic typewriter, which stores input characters from a keyboard in a memory at the same time as printing them, and prints them out again in the same format.
By manually printing some parts from the keyboard, compared to electronic typewriters that print plainly using a display device such as an LCD, the LCD
It is not necessary to include a display device such as, and it is possible to simultaneously create and print a text by inputting one character, and to store the text in memory while checking the format. This makes it possible to greatly improve the efficiency of text creation compared to conventional devices, and requires no display device, making it inexpensive. Providing high-performance electronic typewriters for a long time.
