Outputs the current signal value at the falling edge of 1 to CPU1. Reference numeral 22 denotes a sound data designated amount register in which the amount of sound information is held.

FIG. 3 is a diagram showing the format in which a document is stored on an FD (flexible disk) by the FDD 10, and one document consists of the following three parts. i.e. the document name to identify the document
(D), the start address (E, G) and data amount (F, H) of the document data and sound data stored in each FD, and the creation date of the document,
Document information such as the number of lines of the document is recorded.
FD document information section 18 and document data are recorded.
FD document data section 19 and sound data are recorded.
It consists of an FD sound data section 20.

Here, the operation of one embodiment will be explained below using FIGS. 1 to 3. Sound recording is performed when editing a document, that is, for a document corresponding to the RAM document data section 16. First, the sound (vibration waves)
When it reaches MIC2, MIC2 converts it into a current signal and outputs it to AMPA3. AMPA3 amplifies this current signal and outputs it to A/D4. A/
As mentioned above, upon reception of the sampling signal 21, the D4 converts this current signal (analog amount) into sound data (digital amount), but the CPU 1 controls the start of output of this sampling signal 21 by pressing a specific key of KB13 by the user. Recognize by transmitting information through manipulation. First, the user specifies the amount of data to be recorded (byte unit: tentatively N bytes). This amount of data is recognized by the CPU 1 through the operation of the KB13. The CPU 1 outputs the amount of sound data to be recorded from now on to the sound data specified amount register 22. The register 22 holds this amount of sound data. Next, the CPU 1 outputs "0" to the sound data amount (C) storage section in the RAM document information section 15, initializes the sound data amount (C), and then recognizes the information that the user has started recording sound. Then, the sampling signal 21 is output to the A/D 4. When the A/D 4 receives this sampling signal 21, it converts the current signal from analog to digital as described above, and outputs the sound data to the CPU 1. The CPU 1 writes this sound data to an address equal to the value of the sound data amount (C) of the RAM sound data section 17 in the main storage section 8. Furthermore, the CPU 1 increases (increments) the value of the sound data amount (C) in the RAM document information section 15 by 1,
The increased value is compared with the value in the sound data designation register 22. If a match is found here, the CPU 1 does not output the next sampling signal 21, and recording of the sound ends. Also, if they are not equal, the next sampling signal 21 is output, but since this sampling signal 21 is output after a certain time interval, at that interval, the next sampling signal 21 is output to the A/D 4, and from then on By repeating the above-described steps, recording of the sound is completed.

As a result of the above, in the RAM sound data section 17, sound data of a byte amount equal to the value (N) held in the sound data amount (C) is held at addresses 0 to N-1.

Next, we will explain how to save sound data to an FD.
The sound data is saved when saving the edited document to the FD, which is known for conventional word processors. Under the control of the CPU 1, the contents of the RAM document data section 16 are stored in the document data amount ( B) value,
After writing to the FD document data section 19, the sound data in the RAM sound data section 17 is written to the FD sound data section 20 by the value (N bytes) of the sound data amount (C).
(D), (F), and (H) in the FD document information section 18, respectively.
Values corresponding to (A), (B), and (C) of the RAM document information section 15 are stored, and document data and (G) are stored in (E) and (G), respectively.
The start address of the FD where the sound data is stored, that is, the first addresses of data sections 19 and 20 are
It is saved under the arithmetic control of CPU1.

In this way, sound data is saved along with document storage.

Next, reproduction of sound data will be explained.

Work menus (e.g. "Create document", "Print",
A list of items such as "Calibration/Additions" etc.) is displayed on the CRT 11, but one of them is a menu called "Sound Playback", and by selecting this menu, the sound is saved on the FD. Only sound data can be played. This "sound playback" menu is selected by the user by operating the cursor on the CRT 11 using the KB 13, and a document is designated in the same manner. CPU1 is (D) to (H) of FD document information section 18.
Using this as a clue, search for the sound data of the specified document and transfer the contents of the FD document information section 18 and FD sound data section 20 to the RAM document information section 15 and RAM data section 17 in the main storage section 8, respectively. , write. Then, the CPU 1 reads the value of the RAM sound data amount (C) and compares it with "0". Here, if the RAM sound data amount (C) is "0", the reproduction ends, and if it is not "0", "1" is written into the sound data specified amount register 22. And CPU1 is sound data (1 byte)
is output to D/A5. D/A5 converts this sound data into a current signal and outputs it to AMPB6.
AMPB6 amplifies the input current signal and outputs it to speaker 7. The speaker 7 converts this amplified current signal into sound and outputs it. The CPU 1 reads the contents of the sound data specified amount register 22 and compares it with the value of the sound data amount (C). If the values are equal, the playback ends, and if the values are not equal, the sound data in the RAM sound data section 17 is The sound data (1 byte) at the address of the value C is output to the D/A 5 and reproduced in the same manner as above. The output interval between the sound data and the sound data is the same as the interval between the sampling signals 21 when recording the sound.

Through the above operations, the sound data is played back, and the playback of the saved sound information is completed.

In addition, in the above embodiment, a word processor using an FDD is shown as an example, but it may be replaced with an HDD (hard disk device), or may be replaced with an HDD and an FDD.
It can also be applied to word processing devices that use
It is preferable to use an HDD. ) Records of sound information accompanying documents such as those mentioned above.
By having a playback function, it is possible to reproduce environmental sounds, music, etc. that can only be expressed indirectly or indirectly using words or figures.
Audio information such as speech can be expressed directly and a wide variety of documents can be created.

In addition, the CRT display of the document catalog (which shows document information such as the document creation date, proofreading date, author name, and summary content of the document) found on conventional word processing devices can be replaced with audio output. You can also use it like this.
