DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block circuit diagram showing an embodiment of a recording time correction device for an electronic device according to the present invention. In this embodiment, a description will be given of a communication device (telephone) in which both a telephone with an answering machine function and a telephone with an image communication function (facsimile) are combined as electronic devices.
The communication device 1 is connected to an external line 2 of the telephone.
Are connected to the relay switch 3. A modem 5 is connected to the relay switch 3 via a transformer 4. The modem 5 modulates and demodulates image information transmitted and received by the facsimile apparatus via the external line 2. A telephone 6 with an answering function is connected to terminals a and a 'of the relay switch 3, and a handset 7 provided with a transmitter and a receiver is connected to the telephone 6.

When the called telephone 6 dials the number of the called telephone, a ring signal for calling the called telephone is transmitted from the exchange via the external line 2 to the called telephone, and a ring signal detecting circuit is provided. At 8, a ring signal is detected. And
The detection of the ring signal is transmitted to the control unit (CPU) 9 via the control bus m1. The ring signal for calling the called telephone is a calling signal for the called telephone, and this calling signal is sent to the calling telephone as a ringback tone signal from the exchange to the calling external line 2. And detected by the ringback tone detection circuit 10.
When this ringback tone signal is detected, the control unit 9
Via the control bus m2, and the control unit 9 determines that the called telephone is being called. In addition, a call signal arrives at the called telephone, and the handset 7 of the called telephone is received.
Is raised and the telephone line is activated, this is also transmitted to the control unit 9.

[0007] A ROM 11 is connected to the control unit 9. The ROM 11 has a built-in circuit of the telephone 6 and a clock circuit 1.
2. A program memory for operating the clock display unit 13, the operation unit correction circuit 14, the key input operation unit 15, the facsimile machine and its related circuits. And the control unit 9
Operate according to the program in the ROM 11. More specifically, the control unit 9 stores the first recording medium 16 for voice recording, an OGM circuit 17, a document reading device 18 of a facsimile apparatus, and image information supplied from the modem 5 via an external line. Information recording area (a) and time recording area (b) of the second recording medium 19 such as a semiconductor memory for storing information, and the information recording area (a) of the second recording medium 19
And a printing device 20 for printing on the paper surface by the recording signal of the time recording area (b).

On the other hand, the called side switches the telephone device to the absence mode when going out.
When there is an incoming call via the telephone line and the telephone line is in a talking state, the OGM circuit 17 of the telephone 6 sends the OGM information, that is, "I'm out of the office right now. Please tell me. " When the calling party speaks a message, the message information is recorded in the information recording area (a) of the first recording medium 16 for recording absence messages. When the caller drops handset 7 and hangs up,
The called telephone detects that the call has been disconnected, and this is transmitted to the control unit 9 via the control bus m1, and the control unit 9 clocks the time of the end of the call, for example, "10:21". The time is read from the circuit 12 and the time is stored in the first recording medium 16.
Is recorded in the time recording area (b).

Next, when the clock circuit 12 is ahead of the reference time by, for example, 10 minutes, an input is made at the key input operation unit 15 so as to delay the time by 10 minutes. Then, the operation section correction circuit 14 for time correction works, and the clock circuit 1
In the case where the time of the clock circuit 12 is, for example, the time described above, the time of the clock circuit 12 is corrected to “10:11” by delaying the time of No. 2 by 10 minutes. At the same time, the first recording medium 16
The time record in the time record area (b) is also corrected.

FIG. 2 is a flowchart for explaining the above operation of the present invention. That is, in step (a), whether or not the time of the clock circuit 12 has been corrected, and if the time has been corrected (Yes), the time of the first recording medium 16 is adjusted in accordance with the time correction in step (b). The time recording in the recording area (b) is also corrected. In step (a), the clock circuit 1
If the time is not adjusted (No), the first recording medium 1
The time recording in the time recording area (b) of No. 6 is also not corrected.

Next, the owner of the called telephone 6 returns home,
When the play button of the answering machine of the input operation unit 15 is operated, the recording recorded during the absence is released from the speaker 21, and after the recording is completed, the time recording area of the recording medium 16 is recorded.
The time record of (b) is read out, converted into a voice expressing time by the voice synthesis circuit 22, and the corrected reception end time;
For example, “10:11” is emitted from the speaker 21.

In the case of image communication (facsimile communication), the calling telephone sets the dial number of the called telephone, calls the called telephone, and then transmits the facsimile apparatus at the input operation unit 15. When the button is selected and operated, a 1100 Hz (0.5 second continuous, 3 second interrupted) CNG signal indicating that the calling side is a fax signal is transmitted from the calling side facsimile apparatus. Then, the CNG signal is detected by the facsimile signal detection circuit 23 on the called side, and the fact that the calling side is a facsimile signal is detected and transmitted to the control unit 9. Then, a control signal is sent from the control unit 9 via the control bus m5, and the contact terminals 3A and 3B of the relay switch 3 are switched to the positions of the terminals b and b ', respectively, to form a facsimile circuit. Then, the called party 2100 indicates that it is a facsimile.
After the CED signal of Hz (continuous wave) is transmitted and confirmed on the calling side, facsimile data is transmitted from the facsimile apparatus on the calling side.

In the case of facsimile communication as well, similarly to the telephone 6 with an answering function, when the dialing number is transmitted from the telephone on the calling side and the telephone on the receiving side is in the handset off state (communication state), The time of the clock circuit 12 is read by the control unit 9, and the arrival time is recorded in the time recording area (b) of the second recording medium 19. Then, the facsimile information signal is recorded in the information recording area (a) of the second recording medium 19. Then, in accordance with an instruction from the key input operation unit 15, the recording signals of the information recording area (a) and the time recording area (b) of the recording medium 19 are read and printed by the printing device 11 on the paper. The operation for adjusting the clock circuit 12 to the reference time is also performed in the same manner as in the case of the telephone 6 with an absence function.

In the above description, the time correction of the clock circuit 12 has been described in the case where a person looks at a reference clock and corrects the time. Even when the automatic correction of the time of the clock circuit is adopted, the recording time of the recording medium 10 already recorded according to the present invention may be corrected. Also, the explanation has been given by taking as an example a telephone with an answering machine and a communication device with a facsimile device as an electronic device. When recording the broadcast on the information recording medium in the machine, when recording the reception start time or the reception end time, the time of the clock circuit and the already recorded time may be corrected. Also, the semiconductor memory has been described as an example of the recording medium 10, but the first and second recording media 15, 19 may be a magneto-optical disk, a magnetic tape, or the like. Searching requires a slightly complicated circuit configuration and mechanism. Further, the information recording area (a) and the time recording area (b) of the recording media 16 and 19 may be separate recording media, or the recording area of the same recording medium may be separated so that the information and the time are separated. They may be recorded separately. Further, the first and second recording media may be shared.

[0015]

As described above, in the recording time correcting apparatus for an electronic device according to the present invention, when recording the operation start or end time of the device in the electronic device, the time of the clock circuit is advanced or delayed. Since the operation start or end time of the device also advances or delays from the reference time, it is sometimes necessary to correct the time of the clock circuit, but before the time correction, the time of the operation of the device has already been recorded. In such a case, a great effect that has not been achieved in the past can be obtained that the recording time can be corrected.
