The memory card 6 is removable from the device 1. When the memory card 6 is attached to the device 1, the memory card 6 and the microcomputer 7 exchange various signals with the address bus and the data bus. Is connected with the signal line for.

The microcomputer 7 has a function code table 15
Is provided. The function code table 15 associates the input value with various functions described later, and the microcomputer 7 uses the function code table 15 to convert the value input from the analog volume switch 13 into a function code. By doing so, various functions of the device 1 are executed. For the function code table 15, for example, an electrically erasable batch erasable programmable read only memory (hereinafter referred to as “F-EEPROM”) is used. Details of the memory card will be described later.

The microcomputer 7 has an external interface 16 for transmitting and receiving with an external device. The external interface 16 is used, for example, as a means for connecting a host machine to the device 1. The user inputs a command for controlling the operation of the device 1 or switching the mode via the external interface 16. The user can also transfer the data to the microcomputer 7 and rewrite the contents of the function code table 15 via the external interface 16.

The key switch 12 is for REC (recording), R
Key switches such as EC STOP (stop recording), D-MARK (index addition), D-MARK SKIP (index skip), and ERASE (erase) are included. D-MARK means that the data recorded until the D-MARK key is pressed is made into one document and index information is added to this document.
D-MARK SKIP refers to adding index information to a plurality of documents at once when recording of the last document is completed without adding index information to individual documents.

The functions instructed by the analog volume switch 13 include EOD-SKIP (skip to end of data), REWIND (reverse), STOP (stop), PLAY (playback), FF (forward), and BOD-S.

The operation of the device 1 will be described. At the beginning,
The operation during recording will be described. The microphone 2 converts the input voice into an analog voice signal. The input amplifier 3 amplifies this audio signal to a predetermined level and the A / D converter 4
Send to. The A / D converter 4 converts the input analog audio signal into a digital signal. Then, the audio compression circuit 5 compresses the digital audio signal so that the volume of the digital audio signal becomes 1 / tens to 1/10. The reason why the data is compressed in this way is that if the data is recorded in the memory as it is, a large-capacity memory card 6 is required, which is uneconomical.

The microcomputer 7 once reads the data compressed by the voice compression circuit 5, and writes it in the memory card 6 by designating an address. The microcomputer 7 repeats the operation of sequentially fetching data from the voice compression circuit 5 and writing it to the memory card 6 while incrementing the write address.

Next, the operation of the apparatus 1 during reproduction will be described. The microcomputer 7 specifies an address on the memory card 6 and reads data from the specified address. Microcomputer 7
Sends the read data to the voice expansion circuit 8. The audio expansion circuit 8 expands the data compressed by the audio compression circuit 5 into a digital audio signal of the original volume. Next, the D / A converter 9 converts the expanded digital audio signal into an analog signal. The output amplifier 10 amplifies this analog signal to a predetermined level. The amplified analog audio signal is sent to the speaker 11 and the speaker 1
1 plays as voice.

The operation during such recording and reproduction is as follows.
It is controlled by operating the key switch 12 and the analog volume switch 13 connected to the microcomputer 7. The outline of the operation of the device 1 will be described. When the REC key included in the key switch 12 is pressed during recording, the microcomputer 7 starts the operation of recording the voice input from the microphone 2 in the memory card 6. D- during recording
When you press the MARK key, the voice data recorded up to that point is made into one document, and it is stored in the memory card 6.
The index information is recorded together with the audio data. In this way, voice is recorded as one or more document data until the REC STOP key is pressed. In addition, in order to add index information during recording, D-MARK key or D-MA
Although the RK SKIP key is used, the same index information is added to the document data at the start and end of the insert recording or overwriting recording.

Next, the outline of the operation during reproduction will be described. When the analog volume switch 13 is slid to the PLAY position, the signal recorded in the memory card 6 is read and the sound is reproduced from the speaker 11 according to the procedure described above. At this time, since the data recorded in the memory card 6 is digital data, the DSP (DigitalSig
It is possible to play the voice fast or slow without changing the pitch by connecting and cutting the voice waveforms using a nal processor). By applying this principle, it is possible to realize the function of changing the operation speed during reproduction, which will be described later.

The analog volume switch 13 is FF
Alternatively, when it is slid to the REW position, the forward or backward movement is executed at the speed corresponding to that position. Also, the analog volume switch 13 is EOD-SKI
When it is slid to P or BOD-SKIP position,
A skip is performed at the end or beginning of the data. This cueing process is instantaneously performed in the case of a semiconductor memory. The user can know the operating status of the device 1 by referring to the data displayed on the display panel 14.

The signal output by 3 is obtained as a converted value. Microcomputer 7
However, in the case of a configuration having no analog comparator terminal, an A / D converter may be provided outside the microcomputer 7. The microcomputer 7 refers to the obtained conversion value in the function code table 15 (see FIG. 1) to obtain the function corresponding to the conversion value, and determines the function to operate.

The signal output from the analog volume switch 13 is an A / D provided inside or outside the microcomputer 7 depending on its voltage.
By the operation of the converter, it is converted into a data value that can be processed by the microcomputer 7. This converted data value is the above-mentioned volume value and is the number shown on the left side of the figure. The conversion value is used in the range of 00 to FF (hexadecimal notation).

It is divided into 5 ranges of converted values 6F to 7B, and 1.1 to
A 1.5-speed double speed mode of 1.5 is assigned. In the case of fast-listening reproduction, the converted value range 97 to B4 is divided into 10 ranges and assigned to the 10-speed double speed mode of 1.1 to 2.0. To change the operation speed according to the conversion value range, set REWIND of conversion values 04 to 49,
