Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a text creation machine using a computer, a so-called word processor, and is intended to simplify operation.

This type of word processor includes, for example, a keyboard switch device arranged in the same arrangement as a typewriter, a signal processing circuit that converts the signal from the keyboard device into a code signal, and a signal processing circuit that decodes the code signal to generate instructions. It consists of a display device that displays the characters that have been written, and a recording device that records code signals on a recording medium.

In such a word processor, when an arbitrary sentence is input from a keyboard device, that sentence is coded character by character and displayed on a display device, and a code signal is recorded on a recording medium. Therefore, by reproducing this recording medium at a desired time, the above-mentioned arbitrary sentence can be retrieved, and this sentence can also be easily corrected by operating the keyboard device.

By the way, even in such a word processor, it is necessary to insert a so-called carriage return code at the end of each line. However, in general, skilled users do not look at the display screen while inputting keys, and do not pay attention to the number of characters input. For this reason, in the past, the number of characters input was counted, and when the number reached, say, 80 characters in one line, an alarm buzzer or bell sounded, which prompted the user to input the code for the carriage return. However, this method requires a lot of effort to operate, and there are problems in that key input operations are interrupted and operations do not proceed smoothly.

The present invention provides such a word processor in which carriage return codes are automatically stored. An embodiment of the present invention will be described below with reference to the drawings.

First, FIG. 1 shows the operating section of a word processor according to the present invention. In the figure, 1 is a keyboard device in which key switches corresponding to each letter of the alphabet are arranged in an arrangement similar to that of a typewriter. Reference numeral 2 denotes a display device in which, for example, 40 5×7 dot matrix liquid crystal display sections are arranged side by side. A recording device 3 is provided with a so-called microcassette type tape recorder. Furthermore, a control switch 4 for the tape recorder and an editing switch 5 used for correcting text, etc. are provided. Further, 6 is a speaker, 7 is a microphone, and 8 is a power switch.

The internal configuration of this device is as shown in FIG. That is, an output signal from the keyboard device 1 is supplied to a key encoder 11, and this encoded signal is supplied to a central processing circuit (CPU) 12 constituting a signal processing circuit. This processing circuit 1
2 is supplied to the display device 2 through the matrix encoder 13.

Furthermore, the processing circuit 12 has an interface circuit 1.
4 is connected. A memory 15 is connected through this circuit 14.

Further, the signal from the circuit 14 is supplied to the recording device 3 through the mixing circuit 16. Note that in the circuit 14,
The "1" in the code signal is converted into a tone burst signal of 600 Hz, and the "0" in the code signal is converted into a tone burst signal of 300 Hz and supplied to the recording device 3. Furthermore, the audio signal from the microphone 7 is supplied to the mixing circuit 16 through the amplifier 17. A muting signal from the circuit 14 is also supplied to the amplifier 17.

Furthermore, the reproduction signal of the recording device 3 is supplied to the circuit 14. In addition, in circuit 14, 600Hz in the reproduced signal
The signal at 300 Hz is converted to a code signal of "1" and the signal of 300 Hz is converted to a "0" code signal. Further, a reproduced signal is supplied to the speaker 6 through the amplifier 18. Additionally, a muting signal from circuit 14 is supplied to amplifier 18.

Also, signals from switches 4 and 5 are supplied to circuit 14. A signal from this circuit 14 is then supplied to a system control circuit 19 of the recording apparatus.

In this device, when an arbitrary sentence is input from the keyboard device 1, this signal is sent to the processing circuit 12.
and stored in the memory 15 through the circuit 14. This memory 15 has one page, for example 80
It has a storage capacity that can accommodate code signals of 40 characters x 40 lines.

And the text entered from keyboard device 1 is
When 80 characters are reached or when the user operates the carriage return, the code of the carriage return is stored in the memory 15 according to a command from the processing circuit 12.

That is, FIG. 3 shows a flowchart of a program stored in a read-only memory (not shown) built into the processing circuit 12. In the figure, the numbers in circles indicate that the same items are connected to each other.

In the figure, when an arbitrary key is operated in block 1, it is determined in block 2 whether or not the operation is a carriage return operation;
At block 4, it is determined whether or not the operation is for inputting characters, and at block 4, it is determined whether or not the operation is for setting the number of characters in one line (right margin).

First, when block 4 detects that the operation is to set the write margin, block 5 sets the write margin flag (RMF) in the random access memory (RAM) (not shown) built in the processing circuit 12. is set to 1.

Further, in block 6, it is determined whether RMF is 1 or not, and when RMF=1, it is determined in block 7 whether or not the number of characters is specified. When the number of characters is specified, the number of characters is stored in a predetermined section S of the RAM in block 8. Also, in this block 8, RMF is set to 0 and the write margin set flag (RMSF) is set to 1.

Further, in block 9, it is determined whether RMSF is 1 or not, and when RMSF≠1, 80 is stored in the above-mentioned predetermined section S in block 10.

Block 11 then executes another routine and returns to block 1.

If block 3 detects that the operation is a character input operation, block 12 encodes the character and stores it in a predetermined portion C of the RAM. Further, in block 13, the number of characters stored in the predetermined section N of the RAM is compared with the number stored in the above-mentioned predetermined section S plus one. If these do not match, the contents of the predetermined portion C are written in block 14 to the address corresponding to the numerical value of the predetermined portion N described above in the memory 15, and furthermore, in block 15, the contents of the predetermined portion C are written to the address corresponding to the numerical value of the predetermined portion N.
is incremented by 1 and returned to block 1.

Also, in block 13, the number of coded characters stored in the predetermined part N of the RAM is determined by the number of coded characters stored in the predetermined part S.
When it matches the value obtained by adding 1 to the value stored in , the process proceeds from block 13 to block 16, where the code of the carriage return is stored in the address corresponding to the value in the predetermined part N of the memory 15. Then proceed to block 17. In block 17
The numerical value corresponding to the row of the memory address of the memory 15 stored in the predetermined portion L of the RAM is incremented by one. Furthermore, in block 18, the numerical value of predetermined part N is set to 1, and in block 19, the contents of predetermined part C are written to the corresponding address in memory 15 and returned to block 1.

That is, by detecting the carriage return key operation, a carriage return code is recorded in the memory 15 and then stored in the memory 15, after which the process proceeds to the key input 1 step.

If it is detected in block 2 that the operation is a carriage return, the process advances to block 16.
Blocks 16-19 are executed as described above and return to block 1.

In this way, the key-input characters and the carriage return code are written into the memory 15.

Furthermore, the text input from keyboard device 1 is
When the 40th line is reached or the user presses a predetermined switch in the switch 5, this signal is supplied to the processing circuit 12, and the code signals stored in the memory 15 are read in order according to instructions from the processing circuit 12. and supplied to the recording device 3. That is, when the number of code signals generated by key input reaches a predetermined number or by detecting the operation of the carriage return key of the keyboard device 1, a carriage return code is recorded in the memory 15, and then the code signal is stored in the memory 15. The stored code signal is recorded on the magnetic recording device 3. At this time, a command from the processing circuit 12 is supplied to the control circuit 19 and the recording device 3
is put into recording mode. At this time, memory 15
Immediately before reading from the recording device 3, a header code signal including a predetermined synchronization signal, page address, etc. is supplied from the processing circuit 12 to the recording device 3 and recorded.

Also, an audio signal from the microphone 7 is supplied to the recording device 3. When the user presses the record switch in switch 4, this signal is sent to processing circuit 1.
A command from the processing circuit 12 is supplied to the control circuit 19, and the recording apparatus 3 is put into the recording mode. Note that when recording the code signal mentioned above,
The audio signal is muted in the amplifier 17 according to a command from the processing circuit 12 .

Further, when the playback switch of the switch 4 is pressed, this signal is supplied to the processing circuit 12, and a command from the processing circuit 12 is supplied to the control circuit 19, thereby putting the recording device 3 into the playback mode. Immediately after the above-mentioned header code signal is reproduced, the code signal is read into the memory 15. Furthermore, when the header code signal is reproduced, the reproduced signal supplied to the speaker 6 is muted by the amplifier 18 according to a command from the processing circuit 12 for a period necessary to reproduce the code signal for one page described above.

Also, part of the code signal stored in the memory 15 is supplied to the display device 2 through the processing circuit 12 and displayed. Here display device 2
can only display one line of 40 characters, so each line is displayed in half. For example, when inputting from the keyboard device 1, characters forming the first half or the second half of the input line are displayed. Further, when the code signal from the recording device 3 is being read into the memory 15, the characters forming the first half of each read line are displayed.

Furthermore, when a predetermined switch of the switches 5 is pressed, the first half or the second half of an arbitrary line stored in the memory 15 is displayed. In this state, the user can use the switch 5 and the keyboard device 1 to make corrections to the text. Note that the operation using this switch 5 is equivalent to that of a conventional word processor.

The code signal recorded in this recording device is then supplied to a printer device or the like to create a document or the like.

This is how a word processor is configured, and according to the present invention, the carriage return code is automatically written, so the user does not have to perform complicated operations and can smoothly input keys. It can be carried out.
