Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic typewriter that automatically prints using electronic storage and control, and particularly to an electronic typewriter that automatically prints by electronic storage and control. The present invention relates to a printing method in an electronic typewriter that can read specified text from a memory and automatically print it, as well as display it on a display device.

Conventionally, this type of electronic typewriter uses a so-called floppy disk device, which is a permanent memory, to store a plurality of texts, and by operating character keys on the keyboard, the name (symbol, symbol, It is known that by specifying a text (such as an abbreviation), the specified text can be automatically printed.

However, in the conventional method, in the content of the text,
A manual insertion printing location is provided, and when that location is detected while reading and printing the relevant text, automatic text printing is temporarily stopped and the desired character (including spaces) is inserted at that location.
cannot be printed manually.

The present invention has made this possible, and its feature is that the message data is inserted into the text along with the signals that separate it, stored in memory, and the text is read out from the memory and automatically printed. Accordingly, the message data is detected by the above-described divided signals and displayed on the display device, and the automatic printing of the text is interrupted to enable manual printing, and when the entry key is operated, the message data is automatically This will restart printing.

An embodiment of the present invention will be described in detail below with reference to the drawings.

To carry out the method of the present invention, as shown in FIG. 1, an electronic typewriter 1 is electrically connected to a separate conventional floppy disk device 2.

The electronic typewriter 1 includes a keyboard 3, a horizontally elongated display device (for example, a liquid crystal display device) 4 for displaying characters, a carrier 5 equipped with an automatic ink ribbon transport mechanism, an automatic collector ribbon transport mechanism, and an automatic printing mechanism. 5, a spacing motor 6 that automatically moves the paper to the left or right, a platen 7, and a paper feed motor 8 that automatically rotates the platen 7 in the forward or reverse direction.

The keyboard 3 includes a plurality of character keys 9 and a carrier 5 necessary for printing characters.
A space bar 10 for space operation (rightward feed), a carrier return key 11 for returning the carrier 5, and a forward key 12 for moving the display on the display device 4 forward from right to left (forward scroll). , carrier 5 backspace operation and display device 4
A back key 13 for reversing the above display (backward scroll), a collect/daily key 14 for correcting or deleting, a text key 15 for starting input of a text name, a text top search key 16 for searching for the top (first part) of text (performed by display on the display device 4); a text end search key 17 for searching for the end (last part) of text;
Word search key 1 to execute a word search while in word search mode, which will be described later.
8. Line/paragraph search key 1 for line search and paragraph search (described later)
9. An entry key 20 for performing a so-called entry operation, a code key 21 for operating in conjunction with other keys to perform an operation different from the operation by operating that key alone (so-called dual function), and others. The required function keys are provided.

Incidentally, when the code key 21 and the Z key 22 of the character keys 9 are pressed, the word search mode is entered, and by pressing the word search key 18 in this state, a word search can be performed.
Moreover, when the code key 21 and the M key 23 are pressed, a desired message (1) is displayed in the text as described later.
A message input mode is entered in which characters larger than letters and spaces can be inserted, and printing can be automatically stopped by pressing the code key 21 and the S key 24.

Furthermore, the keyboard 3 has an operation mode selector 25, a space selector 26 for adjusting the space amount per pitch of the carrier 5 (standard space amount), and a feed amount per pitch for paper feeding (standard line space amount). A line space selector 27 for adjustment and other necessary selectors are provided.

The operation mode selector 25 is capable of at least a print mode in which printing can actually be performed, an edit mode in which editing can be performed, and the creation of a so-called line format or page format. The format creation mode can be set as desired.

Data from the keyboard 3 having such a configuration is inputted to a system control device 28 including a microcomputer, etc., as shown in FIG. All operations such as printing, collect, space, backspace, paper feed, etc. by the control device 29 are performed under the control of the system control device 28.

The display device 4 includes a display control section 30 and a liquid crystal display section 31, as shown in FIG. and edited data can be displayed in two columns, front and rear.

Therefore, text is normally stored on the disk of the floppy disk device 2 in the following manner (actually, the manner in which it is displayed on the display device 4).

T N＊＊＊T S＊＊＊＊＊＊＊＊＊＊T E Here, T N is the text name, T S is the text start, T E is the symbol indicating the text end, or * is the symbol for each individual The * between T N and T S represents the text name, and the * between T S and T E represents the content of the text.

In addition, T N＊＊＊T S and ＊＊＊＊＊＊＊＊＊＊T E are stored separately on disk, so that the text name and the text content can be read separately. There is.

This electronic typewriter has a ``text insertion editing operation'' that performs editing so that another text (the same text may be inserted) can be inserted and printed at a desired position in the content of a certain text, and the edited text ``Text insertion printing operation'' that prints the text, and ``message insertion editing operation'' that edits the desired message (one or more characters and a space) so that it can be inserted at a desired position in the content of a certain text. , a "message reply insertion printing operation" which manually inserts and prints any character requested by the message based on the edited text, and a display device 4.
``Scroll operation'' that sends the above display one pitch at a time (one character at a time) or one word at a time,
It is possible to perform a "space/auto carrier return changing operation" that changes the first space after exceeding N to an auto carrier return for every fixed number (N). Each will be explained with reference to Figures 5 to 5.

The system control device 28 is divided into a main control section and a memory control section controlled by the main control section, and the circuit shown in FIG. 5 is included in the main control section, and the circuit shown in FIGS. The circuit is included in the memory controller.

is written to disk in the same way as in .

Note that printing is not performed in either of the cases of and.

"Text Insertion Printing Operation" Let us take as an example the case where the text edited above and stored on the disk as described above is read out and automatically printed.

-(1) Set the operation mode selector 25 to print mode. At the same time, the editing auxiliary symbol detection circuit 40 shown in FIG. 4 is set.

-(2) Press text key 15. A text start signal is input to the address designation circuit 34, and TN is also displayed.

-(3) Specify the first text name using character key 9. This is the edit data display section 3
3.

-(4) Press entry key 20. - As the display in (3) disappears, the first text name is input to the text name buffer 35, and then the first text name is output from the buffer 35, and the main control unit The first text inside is read. A clock pulse is input to the counting pulse forming circuit 37, a count up signal is input to the count direction control circuit 38, and text data and a write clock are input to the memory 39, and the text data is stored in the memory 39.

Next, a text start signal is input to the address designation circuit 34, a clock pulse is input to 37, and a count up signal is input to 38 to read out the memory 39, and the first text (the front part thereof) is automatically printed. Ru.

During this printing, when L is detected by the editing auxiliary symbol detection circuit 40, the stack pointer 41 (which is reset by the text start signal) moves up, and as shown in FIG. flipflop 42
is set, the gates 43 and 44 are opened, and the shift pulse is input to the shift register 45 via 43 and the text data is input to the shift register 45 via 44, and this input state continues until the detection circuit 40 detects L). do. As a result, the second text name inserted above is detected, and the text name buffer 35 in FIG.
is input.

When a second text name is detected, memory address stacking circuit 46 stacks the memory address signals and text name stacking circuit 47 stacks the text name,
The text name buffer 35 outputs a second text name, and the second text on the disk is read out and automatically printed. L) is detected as described above, the memory address correction circuit 48 performs an address correction of +1 to the memory address stack circuit 46, and both stack circuits 46 and 47 compensate for the delay effect of the delay circuit 49. Since the stacking is stopped after this address correction is completed, the second text is printed consecutively in front of the first text.

When the second text is printed and the detection circuit 40 detects TE, the stack pointer 41 moves down after being delayed by the delay circuit 50, and both stack circuits 4
6 and 47 return to their original states. As a result, the first text name is output from the buffer 35, and the action of the memory address stack circuit 46 on the address designation circuit 34 is also stopped, so that the rear part of the first text is printed consecutively to the second text. be done. When TE is detected as described above, the text end detection circuit 51 outputs a text end signal.

When the printing of the rear part of the first text is complete, it is indicated.

-(5) Press entry key 20. Above - (1)
Return to state.

``Message Reply Insertion Printing Operation'' Assume that the text on the disk has been edited as described above, for example, as follows.

In this case, the above editing auxiliary symbol detection circuit 4
The operation when M and S P are detected at 0 (M and) is as follows.
The only difference is that the case above is the same in other respects.

The character (conceptual term of message) between (M and) M is detected by the circuit shown in FIG. 5 in the same manner as described above and displayed on the edited data display section 33. At this time, the operation of the counting pulse forming circuit 37 in FIG. 4 is stopped by the detection of SP.
Printing operation will stop automatically. The circuit 37 operates again when the entry key 20 is pressed and a message end signal is input.

Once the conceptual term is displayed in this manner, the character key 9 is used to print out the required message response required by the conceptual term.

When the entry key 20 is pressed after printing of the message reply is completed, the text contents are read out again and automatically printed.

In this way, for example, the following sentence can be printed based on the above text.

USPatent application No. 123456 , filed
on January 1, 1900 , now Patent... Here, the underlined portion indicates the message reply inserted and printed using the character key 9.

"Scroll Operation" To perform this operation, the operation mode selector 25 is set to edit mode.

The manner of scrolling of the display on the display device 4 differs depending on whether the forward key 12 is pressed lightly or deeply.

- (1) When forward key 12 is lightly pressed (you can keep pressing it). Only one clock pulse is input to the counting pulse forming circuit 37 in FIG. 4, and the clock pulse is scrolled by one character.

-(2) When forward key 12 is pressed deeply.
While the button is being pressed, a scroll repeat signal is input to the timer 52 in FIG. This timer 52 is connected to a word delimiter detection circuit 53.
is detected one word (WD) at a time (memory 3
9), the clock pulse input to the counting pulse forming circuit 37 is stopped for a certain period of time each time. As a result, the display on the display device 4 is skipped one word at a time, which is easier to search than when the words are scrolled continuously without interruption.

In addition to the word (WD), the word delimiter detection circuit 53 also detects an auto carrier return signal (ACR) that causes the carrier 5 to return automatically, and a requisition carrier return signal (RCR) that causes the carrier 5 to return if necessary. .

Furthermore, -(1) and -(2) may be performed separately using different keys.

"Space/Auto carrier return change operation" This operation is performed during the editing process to make it easier to search for already edited content, for example after editing text or in the middle of editing. After performing a requisition carrier return on the keyboard 3, for each number N, the first space entered after exceeding N is changed to an auto carrier return signal (ACR), and by detecting this ACR after the fact, the line or Similar to paragraph-by-paragraph searches, this is intended to be a quick search.

That is, as shown in FIG. 6, spaces in text data and a requirement carrier return signal (RCR) are detected by a space and RCR detection circuit 54.

When RCR is detected, counter 56 is reset via OR circuit 55. counter 56
When the number N of clock pulses is counted, the gate circuit 57 is opened.

After this gate circuit 57 is opened, when a space is detected by the detection circuit 54, it is inputted to the data change circuit 58 through the gate circuit 57, and the space is changed into an autocarrier return signal (ACR). It is stored in the memory 39. At the same time, the counter 56 is reset and starts counting clock pulses again from the beginning. When the number of members N is reached, the gate circuit 57
is opened again, and when the detection circuit 54 detects a space, the space is changed to ACR in the same way as above, and the same process is repeated.

However, the ACR (and
RCR) and search based on that unit, you can search quickly.

Note that the space converted to ACR will be returned to space again when required after the fact.

According to the present invention, when an insertion point is reached during automatic printing of the created text, manual printing is possible while the automatic printing is interrupted and a message notifying the items to be inserted and printed is displayed on the display device. In addition, automatic printing can be restarted by operating the entry key after manual printing, so even if there are many items to be merged, printing can be done efficiently, and input errors by the operator can be reduced. can.
