Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a voice recorder capable of recording or reproducing an audio signal by using a memory having a fixed capacity.

(B) Prior Art Regarding a conventional voice recorder device, Japanese Patent Application Laid-Open No. 59-1920
Publication No. 2 (G11B5 / 627) and Japanese Utility Model Publication 62-147200 (G11C27 / 0)
0) etc.

In this conventional technique, an audio signal is digitally converted by an A / D converter, and a fixed capacity memory, that is, a RAM (Random Acce
ss Memorry), a technique is shown that can immediately reproduce the sound by repeating it as many times as necessary.

(C) Problem to be solved by the invention With a conventional voice recorder device, when a voice signal is once stored in a memory of a certain capacity and a new voice signal is stored in that memory, the memory is always stored from the beginning of the memory. Since it is performed, there is a drawback that the previous data cannot be retained no matter how short the already stored data may be.

Further, Japanese Utility Model Application Laid-Open No. 62-147200 discloses that the light emitting elements are sequentially turned off in accordance with the progress of writing the audio signal to the memory in the recording mode. No measures have been taken to display.

(D) Means for Solving the Problems In view of the above problems, the present invention provides a voice recording device using a memory having a fixed capacity, and a selecting unit for dividing or undividing a storage area of the memory, A display element for discriminating the used area of the memory and for displaying the progress of recording or the progress of reproduction in the recording or reproducing mode, and different display modes by the display element in the recording mode and the reproducing mode. We propose a voice recorder characterized by the above.

(E) Action Since the storage area of the memory can be divided and non-divided, data can be stored in each area when the storage area is divided. Further, since the display mode by the display element is made different in the recording or reproducing mode, it is possible to discriminate at a glance whether it is the recording operation or the reproducing operation, and further the progress status of the above two operations is also displayed. You can

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings. First
FIG. 1 is a block diagram showing a circuit configuration of the present invention, in which (1) is a microphone and (2) is the microphone (1).
An amplifier for amplifying the audio signal from (3) is an A / D converter for converting the audio signal into a digital audio signal, and (4) is a memory for sequentially storing the output from the A / D converter (3). (TC51832 manufactured by Toshiba Corp.) with a capacity of 256Kbit.
That is, if the sampling frequency is 16 kbs, the audio signal can be stored in this memory for 16 seconds.
(5) is a D / A converter that converts the digital audio signal stored in the memory into an analog audio signal, and (6) passes only a certain frequency of the audio signal from the D / A converter (5). The band pass filter (7) is an amplifier for amplifying the audio signal from the band pass filter (6), and (8) is a speaker for outputting the audio signal from the amplifier. Amplifier (2), A / D converter (3), D / A
The converter (5) and the bandpass filter (6) are composed of an LSI (9) for controlling voice synthesis (TC883OF manufactured by Toshiba Corp.). (10) is a system control microcomputer (TMP42C70N-8317 for Toshiba Corp.) for controlling the LSI (9) for voice synthesis control.
0) is written to the memory by turning on the recording SW (11), and is read from the memory by turning on the reproducing SW (12). Then, the area of the memory (4) is switched to the A block (128 kbit) and the B block (1) by the block switching SW (13).
It is divided into two (28 kbit) and can be used independently. The microcomputer (10) also has a built-in drive circuit for driving the light emitting diodes (14a) to (14h) indicating the recording time or the reproducing time to emit light.

Next, the operation of the above system will be described. First, the third
When the block switch SW (13) shown in the figure is set to A + B, the storage area of the memory (4) becomes 256 kbit and the recording S shown in FIG.
When W (11) is pressed, the recording mode is activated, and all the light emitting diodes (14a) to (14h) are illuminated at the same time. Can be written for up to 16 seconds, and each time 1/3 of the entire area of the memory (4) is written (every 2 seconds), the light emitting diodes (14a) to (14h) are lit.
(14a) (14b) (14c) (14d) (14e) (14f) (14
g) (14h), then go out.

Next, when the block switch SW (13) is set to the A position, the memory area of the memory (4) becomes 128 kbit of the first half area, and when the recording SW (11) is pressed, it enters the recording mode and at the same time the light emitting diode (14a) ~ (14e) lights up, writing is possible until the time reaches 8 seconds, and each time 1/5 of 128kbit area is written (every 1.6 seconds), light emitting diodes (14a) (14b) (14c)
The lights go out in the order of (14d) and (14e).

Next, when the block switch SW (13) is set to the position B, the memory area of the memory (4) becomes 128kbit in the latter half, and the recording SW (1
Press 1) to enter recording mode, and light-emitting diodes (14a), (14e) to (14h) will light up at the same time, and the 128kbit area
Every time 1/5 is written (every 1.6 seconds), the light emitting diode (14
e), (14f), (14g), (14h), (14a) go out in this order.

Next, regarding the playback operation, when the playback SW (12) in Fig. 2 is pressed, the playback mode is entered, and the block switch SW (13) is set to A + B.
At the position of, every time the memory (4) is read for 0.125 seconds, one LED is lit one by one at the cycle of the light emitting diodes (14a) to (14h). When all are read, the light emitting diode (14a) to
(14h) all goes out.

Next, when the block switch SW (13) is in the A position, the light emitting diode (14
All of the light emitting diodes (14a) to (14h) are turned off when they are read out one by one in a cycle of a) to (14e) and read out.

Next, when the block switch SW (13) is in the B position, the light emitting diode (14e) ~ is read every 0.1 second read from the memory (4).
All of the light emitting diodes (14a) to (14h) are turned off when all are read out in turn in the cycles (14h) and (14a).

Therefore, the light emitting diodes (14a) to (1
It is possible to determine the used area of the memory based on the number of 4h), to know the approximate remaining recordable time, and to know at a glance whether it is in playback mode or recording mode by the display mode. be able to. Furthermore, by dividing the memory, two short messages (voices) of 8 seconds or less can be simultaneously stored in the memory area.

(G) Effect of the invention According to the voice recorder of the invention, a plurality of audio data can be stored at the same time, so that the storage area of the memory can be effectively used and the recording or reproduction mode can be recognized at a glance by the display device. It is extremely useful because you can see the progress.

Therefore, the present invention is convenient to use for message transmission of simple messages.
