It also has a group of keys mainly used in word processor mode, such as a continue key C0NT for instructing to resume operation, and an escape key ESC for canceling a function. Note that index keys and reverse index keys IND, R, and IND for feeding and returning printing paper are also provided. Note that the code key C0DE has the function of expanding the function by pressing it simultaneously with any of a group of various keys. For example, by simultaneously pressing the code key Cot)E and the tab set key TAB, it is possible to set a decimal tab at the digit where the current blink head is located. Also, in the normal operation of the cursor key Cu, the cursor moves one character per press, whereas the code key C0DI! When the cursor movement key Cu and the cursor movement key Cu are pressed at the same time, the cursor moves to the beginning or end of the line in one motion, which is what is called express cursor movement. Also, pack space key B
, SP moves the carriage to the left by -space when the process is pressed, erases the characters on the display area, forms a space, and moves to ζ, whereas the code key C0IIU and bank space keys B and S11 When pressed at the same time, the carriage returns to the beginning of the line in one motion, and all characters on the display section I are also erased, a so-called express pack space operation is performed.

This keyboard 1 part 1 (is equipped with an appropriate display part, including letters and numbers corresponding to the pressed key,
Displays corresponding to the data in the storage device and the setting mode are selectively performed for convenience in production. This display section can be, for example, a liquid crystal display (LCD) with an appropriate number of digits, which is advantageous in terms of power consumption, element size, etc., but in order to make the entire device handy, ■It is often selected to be much shorter than the print line, for example, about 20 to 30 columns.

Note that a connector CN for use of this device as a data transmitting/receiving device is provided at an appropriate position such as on the side surface of the keyboard section. Furthermore, when the device is configured for handy portability, a carrying handle CH is provided as shown.

The no-link part P has a cover C which becomes a paper receptacle when opened during use. There is a platen P'L under the cover C, and a printer head PH that moves along the platen is disposed. This printer head III (is
Although any known structure can be used, a thermal head is advantageous in terms of small size, convenience, and static screen performance. Thermal and do can be printed directly on thermal paper, and on plain paper using a thermal transfer ribbon.

The printer's throat PI (is mounted on a carriage Ca guided by a guide bar CB, and performs printing operations while moving along the platen PL on the paper indicated by the broken line. Paper release lever PR that is held down and released as necessary
is provided.

The electronic typewriter according to the present invention has a power switch SW.
It is turned on and off by When this electronic typewriter is used as a portable typewriter, it is primarily powered by the built-in battery, but it may also be powered by other external power sources, such as commercial power or other sources, using a suitable adapter. It goes without saying that this can be done.

FIG. 2 is a block diagram showing the internal structure of the electronic typewriter according to the present invention. Each of these elements includes the parts disclosed in FIG. 1, such as the keyboard section K, display section, and printer section P, as well as the central processing unit c, pu, storage device ROM, and RAM built into the main body case. etc. Auxiliary circuits for each of these parts include a keyboard driver KD, display controller DC, printer driver interface PI, etc.
There is. Further, in order to enable connection of the mote as a data transmitting/receiving device with external equipment, it has an external interface driver/receiver IR. Therefore, information can be exchanged with devices of the same type, various computers, and external storage devices.

Regarding each of the main halves forming each block in Fig. 2,
It will be obvious to those skilled in the art that most of the components or devices can be constructed using well-known elements or equipment, such as LSI and other circuit elements, printer mechanisms, and the like.

The electronic typewriter according to the present invention prints the current text by switching the mode selector MS shown in FIG.
It can be used arbitrarily in OIIM mode, WP (word processor) mode for storing, editing, and printing files, and TERMINAL mode for data transmission and reception. Therefore, not only a text memory but also an internal buffer is provided in the RAM so that the contents of keystrokes or contents transmitted from the outside can be temporarily stored. Similarly, by providing a display buffer, in addition to printing directly in response to a key press, the contents of the pressed key are temporarily displayed on the display, and the number of displayed digits is exceeded. When using the electronic typewriter according to this embodiment in NORMAL mode or -P mode, format settings can be made using the left and right margin keys LM and IIM and the tafset/clear key. TAll+.

This is done by TAll-. Note that the set mode, etc. is displayed as guidance on the display section.

The electronic typewriter according to the present invention, as shown in FIG.
There is a display device with a shorter number of digits than one printing line of text TXT. Therefore, 1 of the text
It is often unclear which part of the line is being displayed. In order to clarify this, in many conventional devices, the cursor is moved each time the cursor is moved, and when the cursor is no longer moved, the displayed content is used to confirm that the cursor is at the beginning of the line. In the electronic type-like according to the present invention, such inconvenience can be avoided by providing a means to distinguish whether the display is from the beginning of the line or from the middle of the line and to display this. is obtained by eliminating fW.

In other words, if the display on the display device is the display from the beginning of the relevant line of text, a delimiter "〉 ", and when the display starts from the middle of the line, the delimiter "ku'" is displayed to solve the above-mentioned inconvenience.This mark is used only when the display device is LC or D. Although a filled triangle is generally used, it goes without saying that other suitable symbols indicating directions such as "→" and "←" can also be used.

In FIG. 3, a line start pointer LIIP is placed at the beginning of TXT indicating one line of text, a display start pointer DIIP is placed at the beginning of the display device, and a cursor pointer Cu is placed somewhere within the display device. P, and a line end pointer LEP is located at the end of the line. In Figure 3, Kurtzlbo ink Cu, P and line end pointer LE
Although this shows a state in which P and P match, these often do not match in texts that have already been created.

. FIG. 4 shows that in the present invention, text is displayed from the beginning of a line on a display device, or is displayed from the middle of a line.
It is a flowchart for determining and displaying whether there is a child. When this flow starts, in block 10, a line number is set in the display area of the display device. Next, in block 11, the text is read 131111i from the beginning of the line or from the middle of the line. This judgment N corresponds to each time °ζ,L II +)≠l) II P in FIG. In this case, as in block 12, L
Set the delimiter "'ku" in the CD display area.

On the other hand, if the value 1 i is Y, it corresponds to the fact that the line head pointer and the display destination i 1 pointer in FIG. Block 1: Set the delimiter in the LC display area r as shown in block 13.

Then, as in block I4, text is displayed on the LCD display area. Then, as shown in block 15, the contents of the LCD display area are displayed on the LCI of the display section, and this flow ends. In this display, a delimiter (or delimiter) is inserted between the line number and the text, and this display makes it clear at a glance whether or not the beginning of the line is being displayed.

FIG. 5 shows an example of the display of the electronic type-like device according to the present invention over time, and shows the 10th line of text. The state (in al and Tbl, the display is from the beginning of the line, so a rightward derivation) is shown.
There is C. Here, when the number of keystrokes exceeds the number of digits on the display, the delimiter is reversed and becomes ``ζ'' to the left, as in state 1el. During this time, block 1 from block l'l in FIG.
2.13, processing up to block 15 is performed.

In the middle of a line (from C1, if you want to check the beginning of the line again, press the cursor left move key 20 times to move the cursor to the left end, then press the cursor left move key 1
By performing the operation, (e) is obtained via the state @ tc++. This state (IBI is displayed from the beginning of the line, so the delimiter is reversed and becomes "shi". Also, the state ([
By simultaneously operating the code key and the cursor right movement key in the display state I), the state (fl) can be displayed.

According to the electronic typewriter according to the present invention, the content displayed on the display section is from the beginning of the line of the text I, or from the middle of the line. Since it is clearly indicated whether the text is displayed or not, subsequent operations such as checking text, inserting, deleting, and editing can be performed quickly and concisely, making it easier to use. Improve your hands.

Although a preferred embodiment has been disclosed, it will be apparent to those skilled in the art that many variations and modifications may be made within the scope of the invention.
