The CPU 28 reads a predetermined number of data from the start address of each block and writes the phrase number in the block-phrase management table. In this case,
Since voice data is not written, "FFH" is written for all phrase numbers to indicate that fact (see FIG. 13A). Further, if data other than "FFH" is written in all of this block-phrase management table, it means that voice data is written in all blocks, so the CPU 28 determines that recording is impossible. .

The CPU 28 creates the phrase-recording order management table after creating the block-phrase management table. In this case, all the phrase data in the block-phrase management table is "FFH". , It is judged that no voice data has been written at all, and as the data indicating the recording order of the phrases, "F
FH "is written (see FIG. 13B).

The CPU 28 creates the phrase-recording order management table and then the phrase-recording amount management table. In this case, all the phrase data in the block-phrase management table is "FFH". Therefore, it is determined that no audio data has been written,
As data indicating the amount of recorded phrases, "FFF" is used for all.
FH "is written (see FIG. 13C).

Next, when the operator presses the record key 21, the recording operation starts. First, the CPU 28 sets the recording key 21
When is pressed, the block-phrase management table is referred to and the number of blocks in which the phrase data is "FFH" is counted. In this case, all data is "FFH"
Therefore, all 64 blocks can be recorded.
5 (minutes) × 64 = 96 (minutes) It is determined that there is a remaining recording amount.

Next, the CPU 28 refers to the phrase-recording order management table and searches for the data having the largest recording order data other than "FFH". In this case, since all the data are "FFH", the CPU 28
Prepares "00H" as the data to be written in the recording order. However, if the data in the recording order has the largest value other than "FFH", the data obtained by adding 1 to the value is prepared as the data to be written in the recording order.

Then, the CPU 28 refers to the phrase-recording order management table in ascending order of phrase numbers, and searches for a record in which the recording order data is "FFH", that is, the smallest unused phrase. In this case, since the "00H" phrase corresponds to that, "00H" is written as the data in the recording order (FIG. 14).
(See (B)), and the phrase to be recorded is
Recognize as "00H" phrase.

The CPU 28 refers to the block-phrase management table in ascending order of block number, and "FFH".
, That is, the smallest unused block is searched. In this case, all blocks are "FFH"
However, the 00th block with the smallest block number is recognized as the block for writing the audio data, and the phrase number "00H" to be recorded is written in the block-phrase management table (see FIG. 14A).

The CPU 28 means that one block is used as the recording amount data of the 00H phrase of the phrase-recording amount management table "0".
After writing "000H" (see FIG. 14C), CP
When U28 outputs a recording command and data indicating the phrase number to the DSP 31, recording is started. First, CP
U28 selects the display LED to blink according to the remaining recording amount. In this case, since the remaining recording amount is 96 minutes, the display LED 25 blinks at a normal speed. Also, during this recording, if the erase switch 20 is moved in the direction of the arrow in FIG. 4 and the state is held for 3 seconds or more, which is a predetermined time,
Although the oldest phrase is configured to be erased, the description is omitted because it is not directly related to the present invention.

The voice signal to be recorded is converted by the built-in microphone 14a, or the voice signal is input from the television or radio via the voice signal input terminal 14b to the DSP.
31 is input. The CPU 28 has a voice signal input terminal 1
4b is always recognizing whether or not the input pin is connected. If the input pin is not connected, the audio signal from the built-in microphone 14a is input, and if the input pin is connected, the input signal is input. The switching control of the input audio signal is performed so that the audio signal from the pin is input.

The DSP 31 A / D-converts and encodes the voice signal selected as described above, then performs data compression to generate voice data, adds a phrase number, and adds S.
Write to RAM32. FIG. 15 is a conceptual diagram showing a storage state of the audio data written in the SRAM 32.

The DSP 31 notifies the CPU 28 that the writing of the frame has started, and at the same time, the audio data consisting of 32 bytes and the phrase number are SR-framed in frame units.
After writing to AM32, write the next frame at address 00
Write from the data storage area specified by 0020H.
Then, this operation is cyclically repeated until the recording stop command is received from the CPU 28. However, cyclic means that after writing up to the address 7FFFFFH, returning to the address 000000H and repeating writing.

When the CPU 28 receives a message from the DSP 31 that writing of a frame has started, the SR
The flash memory 33 reads data for one frame from 000000H, which is the start address of the AM 32.
Start writing. Also, as described above, the CPU 2
Since No. 8 already recognizes that the block to which the audio data is written is the 00th block, the audio data for one frame is written in order from the data storage area designated by the start address 000000H of the block, and the remaining recording amount is also recorded. By subtracting the time corresponding to the number of frames of the written audio data from, the remaining recording amount during playback (that is,
Remaining time) is recognized, and the display LED to be blinked is changed according to the remaining recording amount. Further, in particular, when the remaining recording amount is less than 30 seconds, the blinking speed of the display LED 27 is set higher than usual in order to inform the operator of that fact.

Further, when the voice data cannot be written to the block currently being written during recording, the CPU 28 repeats this operation to rewrite the block-phrase management table and continuously write the voice data to the next block. While writing, the recording amount data is rewritten by adding 1 to the recording amount data of the "00H" phrase in the phrase-recording amount management table.

FIG. 16 is a conceptual diagram showing a storage state of voice data in the flash memory 33, showing a state in which one frame of voice data and a phrase number are written in the flash memory 33 (in the figure, Shaded area).
The CPU 28 uses the flash memory 33 for recording.
Recognizes the block that is writing the audio data of
When the voice data is written in all the data storage areas of the block, the block-phrase management table is referred to in the ascending order of the block numbers, and the block in which the voice data is to be written next is selected, and the block-phrase management table and the phrase are written. -Rewrite the recording amount management table.

FIG. 17 is a conceptual diagram showing a storage state of voice data in the flash memory 33, and shows a state immediately after the operator presses the recording key 21 again during the recording operation to finish the recording. The CPU 28 writes the voice data and the phrase number over the three blocks from the 00th block to the 02nd block (the shaded portion in the figure), and then, at the final address of the last block of the phrase, Two bytes of data indicating the recording order and two bytes of data indicating the number of frames written in the final block (that is, the 02nd block) are written. In this case CPU
Since 28 is the first recorded phrase as the data indicating the recording order, "0000H" is written, and if it is assumed that the half number of the 02nd block is recorded as the data indicating the number of frames, "03FFH" is written. ”
Write.

FIG. 18 is a conceptual diagram showing a block-phrase management table, a phrase-recording order management table, and a phrase-recording amount management table. FIG. 18A shows
The block-phrase management table is shown. In this case, since voice data is written in the 00th to 02nd blocks and voice data is not written in the other blocks, the CPU 28 indicates the first phrase as the phrase number of the 00th to 02nd blocks. "0
"0H" is written, and the phrase numbers of other blocks remain "FFH".

In the standby state immediately after the end of recording, the CPU 28 recognizes "00H" which is the number of the recorded phrase. 18B shows a phrase-recording order management table, which is exactly the same as FIG. 14B. FIG. 18C shows a phrase-recording amount management table. In this case, since the audio data is written in the three blocks of the 00th to 02nd blocks, the CPU 28 writes "0002H" which means the three blocks as the recording amount data of the 00th phrase.

B) Voice Data Recording Operation After setting and managing the internal state, the CPU 28 always recognizes whether or not the voice data input device 40 is connected to the data input terminal 14c. If the voice data input device 40 is connected, the block-phrase management table, the phrase-recording order management table, and the phrase-recording amount management table are rewritten according to a predetermined communication procedure, and the already-compressed voice data is voiced. From the data input device 40 to the data input terminal 14c, I /
Writing directly to the flash memory 33 via the O interface 30 and the bus 29. Therefore, the recording time in this case depends on the transfer speed at which the voice data input device 40 transfers data, and is generally extremely fast as compared with the case of recording from the built-in microphone 14a or the voice signal input terminal 14b in real time. Can be recorded on.

C) Reproduction Operation Normally, the CPU 28, in the standby state immediately after this recording,
Although the recorded phrase is recognized as the phrase to be played back, when the fast forward key 18 or the reverse key 19 is clicked here, the phrase-recording order management table is referred to,
In the case of the fast-forward key 18, the oldest phrase is recognized, and in the case of the reverse key 19, the phrase recorded immediately before is recognized as the phrase to be reproduced.

Further, in the voice recording / reproducing apparatus according to the present invention, it is possible to operate the fast forward key 18 and the reverse return key 19 to appropriately select and reproduce a plurality of recorded phrases. The explanation is omitted because it is not directly related to the invention. Next, when the operator presses the reproduction key 7, the reproduction operation starts. As described above, the CPU 28 recognizes that the phrase to be reproduced is, for example, the 00th phrase, which is the latest phrase, and then refers to the block-phrase management table, and the voice of the latest phrase to be reproduced from that phrase number. The block numbers in which the data has been written are read, and the blocks are reproduced in ascending order of block numbers. in this case,
Playback is performed in the order of block 00 to block 02 (see FIG. 14A).

The CPU 28 refers to the phrase-recording amount management table and reads the number of blocks to be reproduced from the phrase number. In this case, the recording amount data is "00".
02H ", it is recognized that the number of blocks is three (see FIG. 14C), and the recording amount data recorded in the final address 4 bytes of the 02nd block having the largest block number (see FIG. 13). ), The total number of frames of the phrase to be reproduced is calculated and obtained by reading the number of frames of the voice data recorded in the last block. In this case, since the voice data is recorded in 2.5 blocks, 2048 × 2 .5 = 5120 (frame).
Therefore, in this case, 3 minutes and 45 seconds have been recorded.

First, the CPU 28 selects a display LED to blink according to the remaining reproduction amount. In this case, since the remaining reproduction amount is 7 minutes and 30 seconds, the display LED 26 blinks. C
The PU 28 continuously reads the voice data of the 00th phrase in order from the beginning of the 00th block, and the SRAM 32
After writing audio data in order from the data storage area specified by 000000H, which is the start address of the
A playback command is issued to 31. At this time, the CPU 28 recognizes the remaining frame number (that is, remaining time) of the phrase being reproduced by subtracting the frame number of the audio data written in the SRAM 32 from the total frame number of the reproduced audio data, Display LED that blinks according to the remaining playback amount
To change. Further, in particular, when the remaining reproduction amount is less than 30 seconds, a display LED is provided to inform the operator of the fact.
The blinking speed of 27 is faster than usual.

The DSP 31 which has received the reproduction command is SRAM
The audio data compressed in order is read from the data storage area of 000000H which is the start address of 32, the data is expanded, D / A converted, the audio signal is output from the earphone jack 8 to the earphone 38, and the audio is reproduced. To do. The CPU 28 continues the operation of reading and writing the audio data until the audio data of the 00th phrase is completely reproduced, that is, until the 02nd block is reproduced or the reproduction key 7 is pressed again. When is finished, a reproduction stop command is issued to the DSP 31. Moreover, the writing of the audio data to the SRAM 32 is performed cyclically. However, writing cyclically means SR
After writing to the last address of AM 32, it means returning to the head address again and repeating writing.

The DSP 31 cyclically repeats the operation of reading and reproducing the audio data, but stops the reproduction when receiving the reproduction stop command from the CPU 28.

[0079]

As described above, according to the present invention, since the data-compressed voice data stored in the voice information distribution device is directly stored in the voice recording / reproducing device, the voice data of the electronic newspaper originally for a long time is stored. Can be recorded in an extremely short time.
