Abstract

PURPOSE:To provide a typewriter comprising a small-type displaying part having a display screen of n characters X 1 line (n is smaller than the maximum number of characters printed in a line), by a method wherein a definite character string is stored at a corresponding position in a document memory, and is printed at a corresponding position. CONSTITUTION:The displaying part is provided with the display screen of n characters X 1 line (n is smaller than the maximum number of characters printed in a line), and a means is provided for recognizing to what digit place in what line in a document the position of each character currently displayed on the displaying part corresponds. After a character string corresponding to an inputted character string is defined, the defined character string is stored at the corresponding position in the document memory 18, and is printed at the corresponding position by a printer. Namely, with a converting key on a keyboard 1 depressed, a KANA-KANJI converting mechanism 3 converts a KANA string stored in an input buffer 2 into a KANJI string, which is written into a conversion result holding part 4. the KANJI string in the part 4 is sent toa display code buffer 11 by a controlling part 5, and a corresponding KANA string in the buffer 11 is replaced by the KANJI string.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a Japanese electronic type-like device having a display section that can display characters of n characters x 1 line (however, n is smaller than the maximum number of characters printed per line). It is related to.

[Prior art and problems]

A Japanese electronic typewriter has a keyboard that can input kana, a display section that displays the input kana string and the kanji string that is the result of kana-kanji conversion, a printer section that prints the created document, and a keyboard that can input kana. It is equipped with a kana-kanji conversion mechanism that converts character strings into kanji character strings.

The display section of conventional Japanese electronic typewriters is composed of, for example, a CRT with a display screen of 48 characters x 22 lines, but conventional Japanese typewriters with CRT displays are relatively expensive and large. It has drawbacks such as being small and heavy.

[Purpose of the invention]

The present invention aims to eliminate the above-mentioned drawbacks, and is a portable Japanese electronic device equipped with a small display section having a display screen of n characters x 1 line (pupil n is smaller than the maximum number of prints per line). The purpose is to provide typewriters.

[Means for solving problems]

Therefore, the Japanese electronic typewriter of the present invention is
This is a Japanese electronic type-like device configured to display character strings input from a keyboard and kanji character strings converted into kana-kanji on a display part, and to print the determined character strings on a printer, the display part being It shall have a display screen of n characters x 1 line (where n is smaller than the maximum number of prints per line), and each character position on the display section currently corresponds to what line and what digit of the document. After determining the character string for the input character string, the determined character string is stored in the corresponding position of the document memory, and the determined character string is stored in the corresponding position in the printer. It is characterized in that it is configured to print on.

[Embodiments of the Invention] First, an overview of the Japanese electronic typewriter of the present invention will be explained.

(b) Regarding the display screen In conventional Japanese electronic typewriters, documents are created on the display screen, but the basic idea of the present invention is to keep the display screen to the minimum size necessary for kana-kanji conversion. The idea is to use the printed results on paper in place of the display screen of conventional Japanese electronic typewriters. In the embodiment of the present invention, a liquid crystal panel is used as the display section, but since the cost of the liquid crystal panel is proportional to the number of displayed characters, the number of displayed characters is made as small as possible.

The size of the display screen of the liquid crystal panel is, for example, 8 characters x 1 line. In Japanese electronic typewriters that use the kana-kanji conversion method, it is necessary to display the input kana character string and the conversion candidate kanji character string on the display screen, but since these are different from the final printed characters, the display screen It is displayed only on the screen and printed after confirmation.

(b) Regarding the ejecting method Since the display screen of the Japanese electronic typewriter of the present invention is small (for example, 8 characters x 1 line), it is necessary to eject characters one after another, and the ejected characters must be printed. There are two ways to remove characters from the display screen: one is to remove characters immediately after the conversion is confirmed, and the other is to remove characters from the display screen by one character to the left when a character is entered from the keyboard with the cursor past the right edge of the display screen. One possible method is to shift the characters to the left end of the display screen and display the characters input from the keyboard at the right end of the display screen.

(c) If you want to refer to the previous and subsequent parts that have already been created regarding the relationship between the cursor and the printer head, press the upward cursor movement key. Then, the character string in the same digit range of the previous line is read from the document memory and displayed on the display screen, and the printer performs a reverse change operation, and the printer head corresponds to the leftmost character on the display screen. position on the printing paper. When the downward cursor movement key is pressed, a printer change operation is performed. When the left cursor movement key is pressed while the cursor is at the left end of the display screen, the entire screen is shifted to the left and the printer head is moved to the left. When the right cursor movement key is pressed while the cursor is past the right edge of the display screen, the entire screen is shifted to the right and the printer head is moved to the right. In this way, the printer head is positioned at the position on the paper where the leftmost character on the display screen is to be printed. In the above explanation, when the screen moves up, down, left, or right, the relative position between the printer head and the paper changes. When changing from the i line to the i-1 line, the printer may perform a line feed or reverse feed operation.

(d) Regarding printing control for characters that overflow from the display screen In a method that prints characters when they overflow from the display screen, if you simply print when the characters overflow from the left edge, the previous line will be When displaying, there is no opportunity to print the characters currently displayed on the screen. Also, when the entire screen is shifted to the left and characters that have already been printed on that line are displayed again, the characters that have not yet been printed on the screen will overflow from the right edge of the screen. Printing characters that overflow from the right edge is difficult for printers that print in one direction (it also damages the ribbon). Therefore, when the printer head moves from the first line to the jiT (i≠j) (when the operator moves the cursor using the cursor up key or down cursor key, or when the printer head moves to the beginning of the line) (e.g., when the left cursor movement key is pressed to move the head to the previous line when the cursor is in the i-th line), characters that have not yet been printed on the i-th line are printed all at once.

If you are constantly printing characters that overflow from the display screen, if you move the cursor under the state where the character string of the already printed part is displayed on the display screen and the characters overflow from the left edge of the display screen, the characters that are already printed on the paper will be printed. More characters are printed in the area where characters were printed. Also, if you want to modify text that has already been manually written, if you print it as is, the original text will be overwritten and become unreadable. Therefore, printing is performed only when characters are written on blank spaces.

(e) Line boundary display Although character strings spanning lines are displayed continuously on the display screen, marks are displayed on the screen to indicate line boundaries. For example, there is a character string "Kyou wa", "Kyo" is at the m-2 to m digit of the i-th line (the m digit is the right end of the range to make a sentence), and "ha" is at the right end of the i-th line , it will be displayed on the display screen as ゞ・kyo [haゞ・ .

(f) About the two calling methods If you keep pressing the left cursor movement key or the right cursor movement key, the screen will shift horizontally and each line will be displayed one after another on the display screen, but the upper When the directional cursor movement key or the downward cursor movement key is pressed, a character string in the digit range just above or below is read from the character memory and displayed on the screen.

The figure is a block diagram of one embodiment of the present invention. In the figure, 1 is a keyboard, 2 is a human cover sofa, 3 is a kana-kanji conversion mechanism, 4 is a conversion result holding section, 5 is a control section, 6 is a character number counter, 7 is a cursor position register, 8 is an effective reading length counter section, 9 is an input status flag section, 10 is a confirmed status flag, 11 is a display code buffer, 12 is a save buffer, 13 is an overflow control section, 14 is a character generator, 15 is a liquid crystal panel, 16 is a printer, and 17 is a format. 18 is a document memory, 19 and 20 are input line buffers, 21 is a comparison section, 22 is an address generation section, and 23 is a +1 circuit. Keyboard 1'l is
Kana characters, alphanumeric characters, etc. can be written manually. The input cover sofa 2 temporarily stores kana character strings input manually from the keyboard 1. The character string of the input cover sofa 2 is stored in the display code buffer 11 via the control section 5. When the conversion key on keyboard 1 is pressed,
The kana-kanji conversion mechanism 3 is activated. When activated, the kana-kanji conversion mechanism 3 converts the kana character string in the manual buffer 2 into a kanji character string, and writes this into the conversion result holding section 4. The kanji character string in the conversion result holding unit 4 is sent to the display code buffer 11 by the control unit 5, and the corresponding kana character string in the display code buffer 11 is replaced with the kanji character string. The control unit 5 controls the entire Japanese electronic typewriter, and includes a character count counter 6, a cursor position register 7, an effective reading length counter 8, an input status flag 9, and a confirmed status flag lO. The character number counter 6 is for displaying line boundaries. The cursor position register 7 indicates the cursor position on the liquid crystal panel 15.

The effective reading length counter 8 indicates the number of kana characters in the kana character string to be converted. When the next character is input from the keyboard 1 after the conversion key is pressed, the kanji character string for the kana character string to be converted is determined. The character string in the confirmed state is stored in the document memory 18. A character code is stored in the display code buffer 11, and the content of the display code buffer 11 is converted into a character pattern by the character generator 14, and the content is converted into a character pattern on the LCD panel 1.
Sent to 5. That is, the liquid crystal panel 15 has a display code.
A character pattern corresponding to the contents of the buffer 11 is displayed.

The save buffer 12 is used to save the contents of the display code buffer 11.

For example, if rABcDJ is written in the display code buffer 11 and the cursor is pointing to rAJ, if you manually type ``1 today'' from keyboard 1, rABcDJ is written.
DJ is replaced with "Kyoha". If you press the conversion key in this state, the characters "Today is DJ" will be written to the display code buffer 11.
For example, it is used to realize such a function.

When the cursor is beyond the right edge of the liquid crystal panel 15, that is, when the value of the cursor position register 7 is "8",
When new characters are sent to the display code buffer 11, the leftmost characters of the display code buffer 11 overflow.
A new character is written to the right end of display code buffer 11. Also, if you press the right cursor movement key when the value of cursor position register 7 is "8", the display code
The characters on the left end of Hesofa 11 overflow, and a blank space is written on the right end of display code Nokunofa 11. The overflow control unit 13 performs controls such as writing characters overflowing from the left end of the display code buffer 11 into the input line buffer 19. The format of the document is determined by the contents of Format Memo January 7. In order to manage the document memory 18, a display start position register is provided. This display start position register indicates the document memory address corresponding to the leftmost digit of the display code buffer 11. Each time the upward cursor movement code corresponding to the upward cursor movement key is input, the contents of the display start position register are incremented by -n (where n is the maximum number of prints per line), and the downward cursor movement code is input manually. Each time, the above contents are incremented by 0. If the leftward cursor movement code is input when the content of the cursor position register 7 is "0", the content of the display start position register is decremented by 1.The content of the cursor position register 7 is "8".
If a rightward cursor movement code is input at this time, the contents of the display start position register are incremented by 1.

The leftmost digit of the display code buffer 11 is from the i-th row to the 3rd digit.
When the line changes, the printer 16 prints the characters that have not been printed yet among the character strings in the i-th line of the document memory 18. The printer 16 is, for example, a thermal printer. After this process is completed, the line feed or reverse feed operation of the printer 16 is performed, the head of the printer 16 is positioned at the jth line position, and the characters on the jth line of the document memo January 8 are stored in the input line buffer 20. written. When the character in the X position of the jth row overflows from the left end of the display code buffer 11, this character is stored in the 21, and if the character in position X of input line buffer 20 is blank, display code buffer 1
The character in the j-th row, X-th column that overflows from 1 is printed on the j-th row, X-th column by the blink 16. When the position in the document memory corresponding to the leftmost digit of the display code buffer 11 changes from the jth line to the jth line, the jth position in the document memory 18 changes.
The printer 16 must print the characters in the string of rows that have not yet been printed. For this reason, the following processing is performed.

Character string al+a2 stored in input line buffer 19
．． - a, and the character strings stored in the input line buffer 20, b2. - Compare with b. b.

If (i=l 2-n) is a blank, change b to a, and if it is not a blank and is a regular character, leave s as is. The resulting string is CI+CZ +-'C
Let it be n. Actually, the character string of the jth line of the document memo January 8th is d,
, d2. -d. shall be. String d+, dz, '-'
Compare d, , and the character string c+ + 02 + "'Cn. If C7 is a blank, leave d, and if d is not a blank and is a regular character, remove d.

Let the character strings obtained as a result be el, C2, -eゎ. This character string e1. The printer 16 prints the characters e2 and ``'en in the corresponding column positions of the jth line.The address generator 22 determines the address when accessing the document memo January 8, and +1 The circuit 23 increments this address by +1.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, it is possible to obtain a Japanese electronic typewriter having features such as being inexpensive, compact, and lightweight.
