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 expand the functionality.

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 code signals, 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.

The present invention enables such a word processor to record audio signals as well as to easily perform the above-mentioned sentence corrections. 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. Reference numeral 3 denotes a recording device, and a so-called micro-cut tape recorder is provided. Furthermore, a control switch 4 for this 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. A signal from this processing circuit 12 is supplied to the display device 2 through a 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 device 3.

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
It has a storage capacity that can accommodate code signals of 80 characters x 40 lines.

And the text entered 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. At this time, a command from the processing circuit 12 is supplied to the control circuit 19, and the recording apparatus 3 is placed in the recording mode. At this time, immediately before reading from the memory 15, a header code signal including a predetermined synchronization signal, page number, 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 setting the recording device 3 in 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 line read 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.According to the present invention, audio signals can also be recorded on the recording medium that records code signals. If this is entered by key, it is suitable for cases where a summary of the following code signal is recorded orally prior to the code signal. In addition, for example, a memory 15 for one page is provided, and after one page's worth of input is performed, a predetermined header code signal is attached and recorded in the recording device 3, so that corrections of sentences, etc.
This can easily be done across a range of pages. Note that in consideration of the case where the number of lines increases due to correction, the storage capacity of the memory 15 may be set in advance to about 1 page + 10 lines.

Although the above-described embodiments have been described using a cassette tape as the recording medium, the present invention is equally applicable to cases where other recording media such as disk-shaped recording media are used.

Claims (1)

[Claims] 1. A keyboard device, a signal processing circuit that converts key input from the keyboard device into a predetermined code signal and stores it in a memory, an input circuit for an audio signal, and a circuit that converts the audio signal and the code signal in the memory into the same code signal. It consists of a recording device that records and plays back on a recording medium, and an acoustic circuit that converts the playback signal into an acoustic signal when the recording device is in the playback state, and the code signal is generated in units of a predetermined number of codes. By recording a header signal indicating a code signal on the recording medium and prior to recording the code signal, when the recording device is in a playback state, the signal processing circuit detects the header signal. The word processor generates a command for causing the acoustic circuit to perform a muting operation for a period corresponding to the predetermined number of codes of the code signal.
