Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a call recording device for recording a call by a telephone connected to a telephone line.

[0002]

2. Description of the Related Art Conventionally, it is common practice to automatically record a telephone call made by a telephone and store the content of the call in a profession such as a lawyer or a company officer. There are several types of call recording device systems that record such calls. Currently, the widely used method is to use a compact cassette as a recording medium. A method using is also realized.

The reason why a mini disk is used as a recording medium of a call recording device is that a relatively long recording time can be secured and random quick access reproduction, which was not possible with a compact cassette, is possible. This is because it is suitable as a recording medium for a call recording device.

FIG. 17 shows a block diagram of a call recording apparatus using the above-mentioned mini disk. In this figure, 101 is a telephone line, 102 is a telephone, 103 is an incoming call detection unit, 104 is a line current detection unit, 105 is a line transformer unit, 106 is a display unit, 107 is a key input unit, 108 is a system control unit, 109 Is a call amplifier, 110 is a BT detection unit, 111 is a mini disk deck unit, 112 is a speaker amplifier, 113 is a speaker, and 114 is a capacitor.

The operation of the call recording device will be described below. When making a call via a telephone line using a telephone, etc., when making a call from the other party from here,
There is a case where an incoming call is received from the other party and the call becomes in response to the incoming call. Therefore, in order to automatically record the content of the call, it is necessary to record both the call made from here and the call received from the other party.

First, when calling from the other party, when the telephone 102 is off-hook to make a call, the line current detecting unit 104 detects the line current flowing through the line and informs the system control unit 108 that the calling state is established. . Then, when the user operates the telephone 102, the telephone number of the other party is transmitted to the telephone line 101, and when the other party answers, the polarity of the telephone line 101 is reversed to inform that the other party has answered. This reversal of polarity is detected by the line current detection unit 104 and transmitted to the system control unit 108, and the system control unit 108 determines that the telephone set 102 is in the call state.

On the other hand, when an incoming call is received from the other party, an incoming call signal is supplied through the telephone line 101, the telephone 102 rings, and the incoming call detection unit 103 detects the incoming call signal and transmits it to the system control unit 108. . Phone 1 here
In response to the incoming call at 02, a line current flows through the line, and the line current detection unit 104 detects this line current and transmits it to the system control unit 108. As a result, the system control unit 108
Determines that the telephone set 102 has entered the call state in response to the incoming signal.

When the system control unit 108 determines that the telephone set 102 has entered a communication state with the other party via the telephone line 101, it instructs the mini disk deck unit 111 to start recording. As a result, the direct current component is cut by the direct current cut capacitor 114 in the voice signal to be communicated via the telephone line 101, and the voice signal is input to the call amplifier unit 109 via the line transformer unit 105. Then, the audio signal amplified by the call amplifier unit 109 is the mini disc deck unit 1
11 and is recorded on the disc, which is a recording medium, by the mini disc deck section 111.

Then, the telephone call with the other party is completed and the telephone 10
When 2 is on-hook, the line current detection unit 104 detects that the line current has stopped flowing and the system control unit 10
Tell 8. As a result, the system control unit 108 determines that the telephone 102 has ended the call and issues a recording stop command to the mini disc deck unit 111, and the mini disc deck unit 111 stops recording.

By the way, even if the other party unilaterally quits the call, the line current continues to flow in the line unless the telephone 102 is on-hook. Therefore, the detection signal is transmitted from the line current detector 104 to the system controller 108. Is not done. In other words, the system control unit 108 determines that the call is still in progress and does not issue a recording stop command to the mini disc deck unit 111, so that the mini disc deck unit 111 remains recording.

Therefore, the busy tone (hereinafter referred to as BT) sent from the telephone line 101 when the other party unilaterally hooks the telephone set is detected by the BT detection unit 110, and the system control unit 108 is detected. Try to tell them. As a result, the system control unit 108
Judges that the telephone of the other party of the call is on-hook and the call has ended, and issues an instruction to stop recording to the mini disk deck section 111, and the mini disk deck section 111 stops recording. In this way, the content of the call with the other party is recorded on the mini disk, which is a recording medium, by the mini disk deck 111 for each call.

When the recorded call is played back as described above, the system control unit 108 is activated by pressing a "play" key button (not shown) provided in the key input unit 107. The mini disc deck section 111 is instructed to reproduce, and the reproduced audio signal is amplified by the speaker amplifier 112 and output from the speaker 113. In this case, the system control unit 108 outputs the track number currently being reproduced from the mini disk deck unit 111, and displays the track number being reproduced on the display unit 106.

When the track next to the track currently being reproduced is reproduced, the system control is performed by pressing a key button (not shown) provided in the key input unit 107, for example, "NEXT". The unit 108 commands the mini disk deck unit 111 to reproduce the next track, reproduces the call contents recorded on the next track, and the display unit 106 displays the next track number. In this way, the call content is reproduced from the mini disk.

[0014]

The call recording device using the mini disk as a recording medium as described above has the following problems. First, the telephone 10
Since the contents of the calls made in 2 are automatically recorded one after another on the mini disk, even the wrong phone call or the contents of the call that do not need to be saved in particular are recorded, and the recordable time of the limited mini disk can be effectively used. I couldn't.

When the recorded contents are reproduced, reproduction is performed from the first track in order to retrieve the desired conversation contents, and the conversation contents recorded on the track are continuously heard for a while, and the reproduced conversation contents are intended. It was necessary to judge whether it was a call content. Further, when the reproduced call is not the intended call content, the next track is reproduced, and this operation needs to be repeated until the desired call is found, which is very troublesome.

Here, as a method for solving such a problem, it is conceivable to give a track name to each track of recorded call contents. However, since it is necessary to manually input the track name each time, it is time-consuming and very troublesome work.

The present invention has been made in view of the above problems, and provides a call recording device that can save only call contents that need to be saved and can easily retrieve desired call contents. The purpose is to provide.

It is recorded in the TOC area.

Here, the U-TOC is provided with a sector for managing the address of each track recorded on the mini disk 30 and a sector for storing the name (track name) of each track. These sectors will be explained.

FIG. 12 shows the format of the U-TOC sector 0, in which the management information about the call recorded by the user and the unrecorded area (free area) where the call can be newly recorded is recorded. Data area. For example, when attempting to record a certain voice on the mini disc 30, the controller 40 searches the free area on the disc from the information of the U-TOC sector 0 and records the voice data there. Also, at the time of reproduction, the area where the audio track to be reproduced is recorded is U
-From the TOC, the area is accessed and the reproducing operation is performed.

Regarding U-TOC, sectors 0 to
Sector 7 is provided. The sector 1, the sector 2, and the sector 4 will be described later, but the other sectors are not directly related to the present invention, and the description thereof will be omitted.

In the U-TOC sector 0 shown in FIG. 12,
First, a header in which a synchronization pattern and a cluster address are recorded is provided, and subsequently, at a predetermined address position, a manufacturer code, a model code, a track number (First TNO) of the first track, and a track number (La) of the last track.
st TNO), sector usage status (Used sectors), disk serial number, disk ID, and other data are recorded. Further, in order to identify a track area or a free area in which audio is recorded by associating with a management table section described later, various table pointers (P-DFA, P-EMPTY, P -FRA
, P-TNO1 to P-TNO255) are prepared for the area to be recorded.

Then, 255 parts tables of (01h) to (FFh) are provided as management table sections to be associated with the table pointers (P-DFA to P-TNO255) of the corresponding table instruction data section. In the parts table, a start address as a starting point, an end address as an ending point, and mode information (track mode) of the part are recorded. In addition, since the parts shown in each parts table may be connected to other parts in succession, link information indicating the parts table in which the start address and end address of the connected parts are recorded can be recorded. Has been done. The part means a track portion in which temporally continuous data is physically and continuously recorded.

In the mini-disc system, the data of one audio program is physically discontinuous on the disc, that is, even if the data is recorded over a plurality of parts, it is reproduced by accessing the parts while accessing them. There is no hindrance. Therefore, for the purpose of efficient use of the recordable area, recording may be performed by dividing it into a plurality of parts. Therefore, link information is provided, and the parts tables can be linked by designating the parts tables to be linked by the numbers (01h) to (FFh) given to the respective parts tables. Note that the link information is actually indicated by a numerical value that is a byte position in the U-TOC sector 0 by a predetermined calculation process.

That is, in the management table section in the U-TOC sector 0, one part table represents one part. For example, link information for an audio program (track) formed by connecting three parts. The position of each part is managed by the three part tables connected by.

Each of the parts tables (01h) to (FFh) in the management table section of the U-TOC sector 0 has a table pointer (P-DF) in the corresponding table instruction data section.
A, P-EMPTY, P-FRA, P-TNO1 to P-TNO255)
The contents of the part are shown as follows.

The table pointer P-DFA is shown attached to a defective area on the magneto-optical disk, and is a part table or a plurality of parts tables in which a track portion (= part) which becomes a defective area due to a scratch or the like is shown. The top parts table of is specified. In other words, if there is a defective part, (01h) ~ (F
One of Fh) is recorded and the defective part is indicated by the start and end addresses in the corresponding parts table. If another defective part exists, another part table is designated as the link information in the part table, and the defective part is also shown in the part table. If there is no other defective part, the link information is, for example, "(00
h) ”and no link after that.

The table pointer P-EMPTY indicates the top parts table of one or a plurality of unused parts tables in the management table section. If there is an unused parts table, the table pointer P-EMPTY is used as the table pointer P-EMPTY. , (01h) to (FFh) is recorded.
If there are multiple unused part tables, the part tables specified by the table pointer P-EMPTY are used to sequentially specify the part tables by link information, and all the unused part tables are linked on the management table section. To be done.

The table pointer P-FRA indicates a writable free area (including an erasing area) on the magneto-optical disk. One or a plurality of parts tables in which parts to be the free area are indicated are shown. The top part table is specified. In other words, if there is a free area, (01h) to (F
Any one of (Fh) is recorded, and the corresponding parts table shows the parts that are free areas by the start and end addresses. In addition, if there are multiple such parts, that is, if there are multiple parts tables, the link information is "(00
h) ”are designated in order.

FIG. 13 schematically shows the management state of the parts which are the free area by using the parts table. This is when the parts (03h) (18h) (1Fh) (2Bh) (E3h) are set as the free area, this state continues to the table pointer P-FRA and the parts table (03h) (18h) (1Fh) (2Bh ) (E3h) shows the state represented by the link. The defective area and the unused parts table management mode described above are the same.

By the way, in the case of a magneto-optical disk in which audio data such as an audio program is not recorded at all and there is no defect, the parts table (01h) is designated by the table pointer P-FRA, and thereby the disk recordable. It is shown that the entire user area is a free area. In this case, the remaining (02h) to (FFh) part tables are not used, so use the table pointer P-EMPTY above to set the part tables.
(02h) is specified, the part table (03h) is specified as the link information of the part table (02h), and so on, and the parts table (FFh) is linked. In this case, the link information of the parts table (FFh) is set to "(00h)" indicating that there is no connection thereafter.

At this time, in the parts table (01h), the start address of the user recordable area on the disc is recorded as the start address, and the address immediately before the lead-out start address is recorded as the end address. It will be.

The table pointers P-TNO1 to P-TNO255 indicate the tracks which are the audio programs recorded on the mini-disc 30, and the table pointer P-TNO1 indicates one or a plurality of data on the first track. The parts table that indicates the temporally first part of the parts is specified.

For example, when the first track is recorded on one part of the disc without being divided into tracks, the recording area of the first track is the table pointer P-.
It is recorded as the start and end addresses in the parts table indicated by TNO1.

Further, for example, when the second track is discretely recorded in a plurality of parts on the disc, each part is designated in a temporal order to indicate the recording position of the track. In other words, from the parts table specified by the table pointer P-TNO2, further parts tables are sequentially specified by the link information according to the temporal order, and the parts table whose link information is "(00h)" is linked. (The above-mentioned form similar to FIG. 13). In this way, for example, by sequentially designating all the parts in which the data forming the second track is recorded, the optical head 32 is accessed when reproducing the second track to reproduce continuous audio information from discrete parts. it can.

Next, FIG. 14 shows the format of the U-TOC sector 1. This sector is a data area for recording input character information when a track name or a disc title is added to each recorded track.

In this U-TOC sector 1, slot pointers P-TNA1 to P-TNA255 are prepared as character slot instruction data portions corresponding to the recorded tracks, and these slot pointers P-TNA1 to P-TNA255 are also provided. The character slot portion designated by is prepared as slots (01h) to (FFh) of 255 units with 1 unit of 8 bytes, and character data is managed in a form similar to that of the above-mentioned U-TOC sector 0.

Character information such as a disc title and a track name is recorded in the slots (01h) to (FFh) in ASCII code. The 8 bytes before the slot (01h) are used as a dedicated area for the disc name.

Then, for example, the character designated by the user corresponding to the first track is recorded in the slot designated by the slot pointer P-TNA1.
Further, since the slots are linked by the link information, the character input corresponding to one track is 7 bytes (7
It is possible to deal with larger characters. In addition, this U-
Even in the TOC sector 1, the slot pointer P-EMPTY manages an unused parts table.

FIG. 15 shows the format of the U-TOC sector 2, which mainly serves as a data area for recording the recording date and time of a telephone call recorded by the user.

In this U-TOC sector 2, slot pointers P-TRD1 to P-TRD255 are prepared as date / time slot instruction data portions corresponding to each recorded call, and these slot pointers P-TRD1 to P-TRD255 are also provided. A date / time slot portion designated by is prepared. In the date / time slot portion, 255 units of slots (01h) to (FFh) are formed with 1 unit of 8 bytes, and date / time data is managed in a form similar to that of the U-TOC sector 0 described above.

The recording date and time of a call (track) is recorded in 6 bytes in the slots (01h) to (FFh). The 6 bytes each contain 1 byte, and the numerical values corresponding to the year, month, day, hour, minute, and second are recorded. The remaining 2 bytes are a maker code and a model code, and code data indicating the manufacturer of the recording device that recorded the call and code data indicating the model of the recording device that recorded the call are recorded. The 8-byte slot before the slot (01h) is an area for recording date and time data for the disc.

For example, when the first call is recorded on the disk, the recording date and time, the manufacturer code and the model code of the recording device are recorded in the slot designated by the slot pointer P-TRD1. The recording date and time data is automatically recorded with reference to the internal clock of the call recording device 1.

The slot pointer P-EMPTY also manages unused slots in this U-TOC sector 2. For unused slots, link information is recorded instead of the model code, and each unused slot is managed by linking with the slot pointer P-EMPTY at the head.

FIG. 15 shows the format of the U-TOC sector 4. This sector is similar to Sector 2 in that it gives a title to the user's recorded call,
When a disc title is attached, it is used as a data area for recording input character information, but here, code data corresponding to Kanji or European characters is recorded.

The management of the character information of the U-TOC sector 4 is designated by the slot pointers P-TNA1 to P-TNA255 and the slot pointers P-TNA1 to P-TNA255 as the character slot instruction data portion, as in the case of the sector 1. It is performed by 255 units of slots (01h) to (FFh). However, the attribute of the character code used as the character code (char code) is recorded in this sector. Also in this U-TOC sector 4, the slot pointer P-EMPTY
Manages unused slots in the form of links.

The operation of the call recording apparatus 1 when the mini disk 30 having the above U-TOC area is used as a recording medium will be described with reference to the flowcharts shown in FIGS.

First, the recording operation of the call recording device 1 shown in FIG. 2 will be described with reference to FIG. When using the telephone 8 to make a call via the telephone line 6, there is a case where a call is made from the other party to enter the call state, or a call is received from the other party and the call state is entered in response to the incoming call. Therefore, in order to automatically record the content of the call, it is necessary to record the call when the call is made from here and when the call is received from the other party.

First, the operation of making a call from here and starting recording the contents of the call will be described. When the telephone 8 is off-hook to make a call, the line current detector 10 detects that a line current has flowed in the line, and the system controller 1
Tell 3 that the call has started (F101, F102, F10
Four). Then, the system control unit 13 monitors the line current detection unit 10 and the PB receiver unit 16 in order to recognize whether the signal transmitted from the telephone 8 is a dial pulse signal or a push button signal (PB signal).

For example, if the telephone line 6 is a dial pulse line, the telephone 8 sends a dial pulse signal. Therefore, the dial pulse signal is detected by the line current detecting section 10 and transmitted to the system control section 13 and is sent to the RAM 13a. Remember. On the other hand, if the telephone line 6 is a push button line, the push button signal sent from the telephone 8 is sent to the PB.
It is detected by the receiver unit 16 and transmitted to the system control unit 13 R
It is stored in the AM 13a (F105).

Then, a dial signal is sent out through the telephone line 8, and when the other party responds, the polarity of the telephone line 6 is reversed to inform that the other party has responded. This polarity reversal is detected by the line current detection unit 10 and transmitted to the system control unit 13, and the system control unit 13 determines that the telephone set 8 is in the call state (F106). At this time, the system control unit 1
3 stores the current date and time in the RAM 13a from the clock unit 21.

On the other hand, when an incoming call is received from the other party and an incoming call signal arrives from the telephone line 6, this incoming call signal is applied to the telephone 8 through the line current detector 10 and the telephone 8 rings and the incoming call is detected. An incoming call can be transmitted to the system control unit 13 by being detected by the unit 11 (F101, F102).

When the telephone 8 answers the incoming call, that is, when the telephone 8 is off-hook, a line current flows in the line. The line current is detected by the line current detection unit 10
Then, the system control unit 13 determines that the telephone set 8 is in the call state (F103). When the information such as the telephone number of the other party is supplied through the ISDN line or the like, the system control unit 13 detects the dial number of the other party and stores the detected dial number in the RAM 13a (F129). At this time, the date and time supplied from the clock unit 21 is also stored in the RAM 13a.

When the system controller 13 determines that the telephone 8 is in the call state as described above, it instructs the mini disk deck unit 17 to record the call contents and stores it in the RAM 13a. The current date and time when the call recording was started
The U-TOC sector 2 held in the AM 42 is written, and the destination telephone number is used as the track name in the buffer RAM 42 and the ASCI is set in the U-TOC sector 1.
Instruct to write with I code (F107).

The audio signal recorded on the mini disk 30 is supplied to the call amplifier 14 via the capacitor 24, the line transformer 12 and the relay 27. The supplied audio signal is amplified by the call amplifier 14 and supplied to the mini disk deck section 17, and the contents of the call are automatically recorded on the mini disk 30 as one track.

When the telephone call is completed and the telephone 8 is on-hook, the line current detection unit 10 detects that the line current has stopped flowing in the line and notifies the system control unit 13 (F108). Then, the system control unit 13 determines that the call has ended, and instructs the mini disc deck unit 17 to stop recording, and the mini disc deck unit 17 stops the recording operation (F110).

When the other party unilaterally quits the call, the system controller 13 determines that the call is in progress because the line current continues to flow in the line unless the telephone 8 is hooked. Therefore, the command for stopping the recording operation is not transmitted from the system control unit 13 to the mini disc deck unit 17, and the mini disc deck unit 17 keeps recording.

Therefore, when the other party unilaterally on-hooks the telephone, the busy tone (BT) transmitted through the telephone line 6 is detected by the BT detector 15 and the busy tone is detected by the system controller 13. Tell them (F109). As a result, the system control unit 13 determines that the call has ended, and issues an instruction to stop recording to the mini disc deck unit 17, and the mini disc deck unit 17 stops recording (F110). As the recording stop processing in step F110, the recording operation on the mini-disc 30 is stopped, and the address (start address and end address) of the track is determined at that time, and the U in the buffer RAM 42 is determined for the track. -TOC sector 0 will be updated.

As a result, the recorded call contents are recorded as one track of the mini disk 30 for each call. In addition, the buffer R
The U-TOC data updated on the AM 42 is recorded on the mini disk 30 at the time of disk injection,
The U-TOC data is updated on the mini disk 30.

Next, the operation after the end of the call is shown in FIG. 7 and FIG.
This will be described with reference to the flowchart shown in FIG. When the system control unit 13 determines that the call is ended, after the process of step F110 of FIG. 6, the process proceeds to step F111 of FIG. 7 to control the relay 27 to the off state, and also control the relay 26 to detect the telephone 8 and the hook. The part 19 is connected.

Then, in order to inquire the user of the necessity of storing the recorded call contents, the voice synthesis data is read from the voice synthesis ROM 22 and output to the voice synthesis unit 23. The voice synthesized by the voice synthesizer 23 by this data is output from the speaker 5 via the speaker amplifier 18, for example, "Is it necessary to save the current call recording?" (F111).

Here, if the user judges that it is unnecessary to save the recorded call contents according to this voice message, the message "unnecessary" of the key input unit 2 of the call recording device 1 as shown in FIG. 4 is displayed. Press the key button 32 (F11
2). This information is sent from the key input unit 2 to the system control unit 13
When the system control unit 13 recognizes that the "unnecessary" key button 32 has been pressed, the system control unit 13 commands the mini disc deck unit 17 to erase the one track in which the call contents up to now are recorded. The disc deck unit 17 deletes the track of the mini disc 30 (F114). That is, the U-TOC data is updated on the buffer RAM 42 so that the track is erased.

Then, the system control unit 13 uses the relay 27
Is turned on and the relay 26 is controlled to connect the telephone 8 and the line current detector 10 to return to the standby state again (F115).

Since the contents of the call once recorded on the mini disk 30 can be deleted at the discretion of the user in this way, unnecessary calls do not exist on the mini disk, and the recording of the limited mini disk is limited. It becomes possible to utilize the time effectively.

On the other hand, when the user determines that the contents of the call that have been recorded so far are necessary, he depresses the "necessary" key button 31 of the key input unit 2 shown in FIG. 4 (F112). This information is transmitted from the key input unit 2 to the system control unit 13, and when the system control unit 13 recognizes that the "necessary" key button 31 has been pressed, the recording of the subject for explaining the contents of the call is performed.

In this case, the system controller 13 instructs the user to record the subject of the recorded call contents, so that the voice synthesizing data for calling the subject recording is read from the voice synthesizing ROM 22. Output to the voice synthesis unit 23. The voice is synthesized by the voice synthesizing unit 23 by this data, and the speaker 5 is passed through the speaker amplifier 18.
From, for example, "the subject will be recorded from the telephone, so please lift the handset and speak the subject" is output (F113).

Then, when the user off-hooks the telephone 8 to record the subject in accordance with the voice as described above, the hook detector 19 detects the off-hook and informs the system controller 13 (F116). The operating current of the telephone 8 in this case is supplied from the current supply unit 20.

When the system control unit 13 recognizes that the telephone 8 is off-hook, it instructs the mini disk deck unit 17 to start recording, and at the same time the RAM is recorded during call recording.
The date and time when the call recording stored in 13a is started by U-TOC
The sector 2 is instructed to write the telephone number of the other party as a track name in the U-TOC sector 1 in the ASCII code (F117).

Then, the user uses the telephone 8 to explain the content of the call, for example, "*** Mr.
We had a meeting about weekend deals. You can speak like this. In this way, the voice signal of the subject input from the telephone 8 is the hook detection unit 19 and the condenser 25.
Is input to the call amplifier 14 via. This voice signal is amplified by the call amplifier 14 and is added to the mini disc deck section 17
And the subject is recorded on one track of the mini disc 30.

When the user finishes talking about the subject and the telephone 8 is on-hook, the hook detector 19 detects the on-hook and informs the system controller 13 (F118). When the system control unit 13 recognizes that it is on-hook, it supplies the current date and time stored in the RAM 13a and data such as the telephone number of the other party to the voice synthesis unit 23. Then, this data is converted into voice by the voice synthesizer 23 and output to the mini-disc deck 17.

In other words, in the mini-disc deck section 17, after the title, for example, "XX year □□ month ☆☆ day ** hour #
# Minutes. The call date and time (and the telephone number of the other party) will be recorded by voice and the operation will be stopped (F119, F1
20). Therefore, the date and time when the call recording is started and the telephone number of the other party are continuously recorded after the subject in the track where the subject is recorded.

Since the date and time of the call and the telephone number of the other party are recorded as data in the U-TOC sectors 1 and 2 as described above, it is not always necessary to record as voice. Further, when recording as voice, recording as data in the U-TOC sectors 1 and 2 may not be performed.

Further, the user inputs “necessary” key button 31 or “unnecessary” key button 32 of the key input unit 2.
If a predetermined time has passed without selecting (F112), or if the predetermined time has passed without recording the subject by off-hooking the telephone 8 even though the "necessary" key button 31 has been selected. (F116), the system control unit 13 uses the date and time such as “XX year □□ month ☆☆ day ** hour ## minutes” and the telephone number of the other party as the subject of the minidisk 30. Record as voice on one track and stop operation (F119, F120).

By the way, as described above, the contents of the call and the subject are recorded as the track 1 and the track 2 on the disk 30. For example, in this case, as shown in FIG. 5A, the call contents are recorded on the track 1 of the addresses A _{1 to} A ₂ , and the subject is recorded on the track 2 of the addresses A _{3 to} A ₄ . Then, the start address A ₁ and the end address A _{2 of} the track 1 where the call is recorded are recorded in the parts table (01h) indicated by the table pointer P-TNO1 of the U-TOC sector 0, for example.

Further, the start address A ₃ and the end address A _{4 of} the track 2 in which the title is recorded are recorded in the parts table (02h) indicated by the table pointer P-TNO2. In other words, the physical position on the mini disk is track 2 where the call was recorded, followed by track 2 where the subject was recorded.
Will be located.

Therefore, when this call content and subject are reproduced, as shown by the arrow at the bottom of FIG. 5 (a), the parts table (01
The call content of track 1 recorded in h) is played, and then the parts table (0
The subject of track 2 recorded in 2h) will be played back, and the meaning of recording the subject of the call will be diminished.

Then, after the end of the subject recording process (F120),
As shown in FIG. 8A, the system control unit 13 commands the mini-disc deck unit 17 to switch the reproduction order of the track 1 in which the call contents are recorded and the track 2 in which the title is recorded (F121). .

For example, in the editing process in this case, the mini disc deck section 17 uses the mini disc 30 for the track 1
The value of the table pointer P-TN01 that is supported on the U-TOC and the track 2
The value of the table pointer P-TN02 corresponding on the U-TOC is updated for the subject track described as. In other words, change the value of table pointer P-TN01 to (0
1h) → (02h), change the value of table pointer P-TN02 to (02h) →
Updated with (01h).

As a result, as shown in FIG. 5B, the track numbers of the subject track and the conversation track are exchanged, and the subject track becomes the track immediately before the conversation track. That is, in the case of playing, the content of the call recording is played after the subject is played first as indicated by the arrow at the bottom of FIG.

Further, the system controller 13 reads the recordable time of the mini-disc 30 inserted from the mini-disc deck 17 and displays it on the display 3 to inform the user how much recording is possible. At the same time, the number of recorded calls is displayed (F122).

After the above operation is completed, the system controller 1
3 turns on the relay 27, controls the relay 26 so as to connect the telephone 8 and the line current detection unit 10, and enters the standby state again (F123).

By the way, for example, the key input unit 2 shown in FIG.
When the contents of the call and the subject are recorded while the MD edit mode key button 39 is operated and the MD edit mode is set, the process of FIG. 8B is executed following step F120 of FIG. Will be done. As shown in FIG. 5 (c), the system control unit 13 sets the call track in which the call content is recorded as track 1 and the track called the track 2 in FIG. d)
After instructing the mini disk deck unit 17 to execute the U-TOC update as shown in FIG.
As shown in (e), the command track and the subject track are instructed to be one track (F124, F125).
In other words, as track 1, part 1 (1) and part 1
U-TOC so that (2) becomes linked management information
To update.

That is, in this "MD editing" mode, the mini-disc deck section 17 drives the mini-disc 30.
About the talk truck, which is called track 1 in UT
Set the value of the table pointer P-TN01 that is supported on the OC
After updating the value of the table pointer P-TN02 corresponding to the subject track, which is supposed to be track 2, on the U-TOC from (01h) to (02h) (02h) to (01h) (Fig. 5).
(State of (d)), the part table (01h) is specified in the link information of the part table (02h) indicated by the value of the table pointer P-TN01, and the link information of the part table (01h) indicates no connection thereafter ( 00h) is specified.

As a result, at the time of reproduction, the track numbers of the subject track and the call track are exchanged, and after that, one track in which the call track is connected is formed after the subject track. Therefore, after the subject recorded in the addresses A _{3 to} A ₄ of the subject track is reproduced, the contents of the conversation recorded in the addresses A _{1 to} A ₂ of the conversation track are continuously reproduced.

Then, the system control unit 13 reads the recordable time of the inserted mini-disc from the mini-disc deck unit 17 and displays it on the display unit 3 to inform how much more recording is possible, and
Displays the number of recorded calls (F126).

After the above operation is completed, the system control unit 13 turns on the relay 27, controls the relay 26 so that the telephone 8 and the line current detection unit 10 are connected, and returns to the standby state again. (F127).

Next, the operation of the call recording apparatus 1 of this embodiment during reproduction will be described with reference to the flowchart shown in FIG. It is assumed that the mini-disc 30 has recorded therein a call track and a subject track managed in the state of FIG. 5B in the process of FIG. 8A. For example, user x
If all the calls are recorded after the call is repeated, it means that there are 2x tracks on the mini disk 30.
The number of tracks is recorded as the last track number (Last TNO) in U-TOC sector 0.

First, the system control unit 13 reads the number of tracks (Last TNo) recorded on the mini disk 30 from the mini disk deck unit 17, and based on this, displays the number of recordings on the display unit 3 (F130). . However, when operating in the normal mode, that is, when not in the "MD editing" mode, the number of calls is half of the total number of tracks because the mini disk has a title track and a call track. The system control unit 13 controls so that half the total number of tracks (Last TNo) is displayed as the number of recordings.

Then, when the user reproduces the call contents and does not know in which track number on the mini disk 30 the call contents to be reproduced are recorded, FIG.
It suffices to press the “subject search” key button 33 of the key input unit 2 shown in FIG. The system control unit 13 sets the variable Y to "1" in preparation for this operation (F131).
When the system control unit 13 determines that the "subject search" key button 33 has been pressed, it accesses the Yth track of the mini disk 30 inserted in the mini disk deck unit 17, that is, the first track in this case. And instruct to play (F132, F134).

The first track to be reproduced is a subject track in which the first recorded call subject is recorded, and the subject recorded in this subject track is reproduced in the mini disc deck section 17 ( F135). Then, the reproduced signal is amplified by the speaker amplifier 18 and output as sound from the speaker 5. Also, for example, the call date and time and the telephone number of the other party recorded on the U-TOC of the mini disk 30 corresponding to the first track are transmitted from the mini disk deck section 17 to the system control section 13 and displayed on the display section 3. Is displayed (F136).

If the "play contents" key button 34 of the key input unit 2 is not pressed by the time the reproduction of the first subject track is completed, the system control unit 13 sets the value of the variable Y to "Y + 2". Yes (F138). If the value of the variable Y is larger than the number of the last track number (Last TNo), the system control unit 13 determines that the reproduction of all the subject tracks has been completed and ends the operation (F139, F1).
40). On the other hand, if the value of the variable Y is smaller than the number of the last track number (Last TNo) in step F139, the Y-th track of the mini disk 30, that is, the third track in this case.
Command to access and play the track (F139,
F134).

Here, the reproduced third track is a subject track relating to the second call, and the subject recorded in this subject track is reproduced by the mini disc deck section 17 (F135). Then, the reproduced signal is amplified by the speaker amplifier 18 and output as sound from the speaker 5. Also, a mini disc 3 corresponding to the third track
For example, the telephone call date and time and the telephone number of the other party recorded on the U-TOC of 0 are transmitted from the mini disk deck section 17 to the system control section 13 and displayed on the display section 3 (F1
36).

In this way, "keyword search" is performed from the key input unit 2.
When the key button 33 of is pressed, the system control unit 1
3 controls to reproduce only the subject track one after another, and the user needs from the contents of the subject sequentially output as voice from the speaker 5 and, for example, the call recording date and time and the destination telephone number displayed on the display unit 3. Try to find a good call recording.

When the user judges that the subject of the searched call is reproduced, the user presses the "content reproduction" key button 34 shown in FIG. 4 during reproduction of the subject track (F137). ). Then, the system control unit 1
3 sets the value of the variable Y at that time to "Y + 1" and commands to access the Yth track (F141, F142). That is, control is performed so as to reproduce the call track located on the track next to the title track that was being reproduced.

Then, the contents of the call recorded on the Yth track are reproduced by the mini disc deck section 17 (F14
3). Then, the reproduced signal is amplified by the speaker amplifier 18 and output as sound from the speaker 5, and after the reproduction is completed, the standby state is resumed (F144).

By controlling in this way, for example, only the contents of the subject recorded in the subject track, which is an odd number track, are sequentially reproduced, and if the user listens to this subject and judges the contents of the conversation, the desired conversation can be easily performed. You will be able to search the contents.

If the "play" key button 35 is pressed without pressing the "subject search" key button 33, the system control unit 13 starts recording the recorded contents recorded on the mini disk 30 from the first track. Instruct to play sequentially. That is, in this case, first, the title of the first call recorded on the first track is reproduced, then, the content of the first call recorded on the second track is reproduced, and the second call. Replay of the subject, second call content, and so on.

Therefore, the user operates the key button 37 of the "next track" to reproduce the title track in which the title is recorded and, for example, the call date and time and the destination telephone number displayed on the display unit 3. You may make it search the target telephone call by judging the content of the telephone call.

Next, description will be made on a case where the mini disc 30 recorded in the mode of the call and the subject of "MD editing" is reproduced. In this case, the mini disk 30 is shown in FIG.
In the process of (b), the call track and the subject track managed in the state of FIG. 5 (e) are recorded. That is,
Edit processing is performed and recorded so that the call track and the subject track are one track.

Therefore, in the case of this mode, if it is assumed that the call has been made x times and all of this has been recorded, the mini disc 30
There will be x tracks in. The number of tracks is recorded as the last track number (Last TNo) in the U-TOC sector 0.

Then, the system control unit 13 reads the number of tracks (Last TNo) recorded on the mini disk 30 via the mini disk deck unit 17, and based on this, displays the number of recordings on the display unit 3.

However, in this mode, since the subject track and the communication track are connected and edited and recorded so as to be one track, the subject track,
Or it is not possible to play only the call track. For this reason, the "keyword search" key button 33 for accessing and playing only the above-mentioned subject track, and "content playback" for pressing and accessing the call track corresponding to the subject when the subject is being played Key button 3
Even if 4 is operated, the system control unit 13 determines that it is invalid.

Therefore, when the user reproduces the call contents recorded in this mode, the user presses the "play" key button 35 shown in FIG. 4 from the key input unit 2. As a result, reproduction is performed in order from the head track of the mini disk 30. In other words, the subject and call contents of the first call are reproduced, then the subject and call contents of the second call are reproduced, and so on, and the subject and call contents are sequentially reproduced. Further, the call date and time recorded on the U-TOC of the mini disk 30 and the telephone number system control unit 13 of the other party are transmitted and displayed on the display unit 3.

Therefore, in order to search the call contents in this mode, the time when the user hears only the first reproduced title (that is, the time when the call contents have not been reproduced yet) or the display unit 3 displays For example, if it is determined that the call content is not searched at the time when the recorded call date and time or the telephone number of the other party is viewed, the key button 37 of the "next track" shown in FIG. 4 may be pressed. Then, the system control unit 13 recognizes that the "next track" key button 37 has been pressed, and instructs the mini disk deck unit 17 to reproduce the track next to the currently reproduced track.

As a result, the title recorded on the next track is reproduced, and the call date and time of the next track and the telephone number of the other party are displayed on the display unit 3. Therefore, by repeating this operation, the user can easily search and reproduce the necessary call content from the subject and the display content of the display unit 3.

In the call recording apparatus 1 of this embodiment, if the user depresses the "STOP" key button 36 shown in FIG. 4, the system control unit 13 will be the mini disk deck unit 1.
7 is instructed to stop the reproducing operation, and when the "previous track" key button 38 is pressed, the mini disk deck section 17 is instructed to reproduce the previous track. In other words, it works like a normal mini disc deck.

As described above, in the MD edit mode, when the subject track and the call track are combined into one track, the call can be reproduced for each case by the same operation as that of a normal mini disk. Therefore, for example, a search of the contents of the mini disk 30 in which a call is recorded is not performed by using the call recording apparatus 1 of the present embodiment, but a similar portable or stationary mini disk reproducing apparatus is used. It is also possible to easily find the content of the call by performing an operation.

Further, if the function for displaying the track name is provided, it becomes possible to display the date and time when the call was recorded and the telephone number of the other party, so that the portable mini disk reproducing device can be used on the train while commuting to work. You can easily listen to it or search the contents of the call using a mini disk deck of a general household.

Next, the second embodiment will be described. FIG. 10 shows the configuration of the key input unit of the call recording device of the second embodiment. In this case, as compared with the key input unit 2 of the call recording device 1 of the first embodiment described above, the "MD edit" key button 39 is deleted. The rest of the configuration is the same as that of the call recording device 1 shown in FIG. 1 and FIG.

In the case of the configuration of this embodiment, when the user judges that the contents of the call need to be stored and presses the "necessary" key button 31, the mini disk 30
In this case, the communication track and the subject track managed in the state of FIG. 5 (b) by the processing of FIG. 8 (a) described above are always recorded. In addition, when reproducing the call contents recorded on the mini disk 30, the "subject search" key button 33
By operating, the only subject tracks (that is, only odd number tracks) are sequentially reproduced from the subject track of the call recorded on the first track. Then, when the subject of the intended call is reproduced, by pressing the "play contents" key button 34, the conversation track recorded on the track next to the subject track can be reproduced.

Further, without operating the "subject search" key button 33, the "playback" key button 35 is operated to play back sequentially from the first track.

It is also possible to use the track number as the subject track and search only for this even number of tracks. Further, the file name recorded on the U-TOC of the mini disk 30 as the management information is, for example, the telephone number of the other party, but other information may be managed as the file name. Also, U-TO
The management information of the subject track recorded on C may not be recorded.

According to the present invention, the contents of a telephone call by the telephone device can be recorded on the disk as a telephone call track, and if it is necessary to save the telephone call contents after the end of the telephone call, a track continuous to the telephone call track. The number track is recorded in the number, and the call track that recorded the call contents is deleted if there is no need to save it, so only the necessary call contents are reliably saved, and the recording medium is limited. The available time can be used effectively.

Further, since the subject corresponding to the call contents is recorded as the subject track, it is possible to easily reproduce the required call contents in a short time by searching only this subject track. Furthermore, after recording the call track and the subject track, the track numbers of the call track and the subject track can be exchanged so that they can be linked to one track, so that it can be easily used with a general playback device. You can search and play the call content.

Further, since the content recorded as the management information of the call content on the recording medium is displayed on the display unit during reproduction, it is possible to search for the necessary call content based on this information.
