The ring detector 21 detects ring signals of the external telephone lines L1 and L2, converts the ring signals into digital signals, and transmits them to the microcomputer 22.

The microcomputer 22 controls the operation of each unit by a program.

The input selector 23 selects a line to turn on / off a transistor according to the high / low output signal of the microcomputer 22 or a tuner to receive a broadcast signal or a line to receive a broadcast signal. do.

The hook switch 24 has an output signal of the microcomputer 22 transmitted to the base of the transistor so that the transistor is turned on / off and the relay is turned on / off so that the hook-on state (phone call state) or the hook-off state (call blocking state) is performed. State).

The voice signal generator 25 receives voice data of the microcomputer 22, converts the voice signal, and transfers the changed voice signal to the audio circuit unit 26.

The audio circuit unit 26 receives the voice signal of the voice signal generator 25 and transmits the voice signal to the signal transmitter 27 and the deck unit 29, and through the signal transmitter 27 and the input selector 23. The voice signal of the external user is transmitted to the deck unit 29 so that the voice signal is recorded.

The signal transmission unit 27 transmits a voice signal transmitted from the audio circuit unit 26 to an external user through an external telephone line switch, and transmits a tone signal and an audio signal of the external telephone to the tone decoder 28 and the input selector ( 23).

The tone decoder 28 receives the tone signal of the external telephone through the signal transmission unit 27, converts the tone signal into a digital signal, and transmits the decoded tone signal to the microcomputer 22.

The deck unit 29 is driven by the output signal of the microcomputer 22 and receives audio and video signals from the audio circuit unit 26 and the head amplifying unit 30 and records them on a tape.

The video circuit unit 31 receives an image signal input through the input selector 23, transmits the image signal to the head amplifier 30, and transmits the image signal of the deck unit 29 through the head amplifier 30. And outputs to the synchronization separator 32.

The sync separator 32 receives the video signal from the video circuit 31 and outputs to the microcomputer 22 a sync signal obtained by synchronizing and separating the digital signal.

The A / D converter 33 digitally converts an audio signal transmitted through the audio circuit unit 26 and outputs the digital signal to the microcomputer 22.

2 is a flowchart illustrating the operation according to the present invention. When an external user makes a phone call in step 101, a ring signal transmitted through external telephone lines L1 and L2 is detected by the ring detector 21 and transmitted to the microcomputer 22. If so, the microcomputer 22 outputs a low signal to the input selector 23 in step 102 to bring the input selection to the LINE position, and turns the hook switch 24 to the hook on state (telephone). In the step 104, the voice data is transferred to the voice signal generator 25 and converted into a voice signal. For example, the scheduled recording is a * mark, the message record is 1 time, and a message. In the step 104 of transmitting a selection guide note, such as a desired number 2, to the external user through the audio circuit unit 26 and the signal transmission unit 27, the input tone is inputted when the external user inputs the number of the phone. Signal is decoded via the signal transmission unit 27. In step (105), the digital signal is converted into a digital signal and transferred to the microcomputer (22) to determine whether there is data input for a predetermined time. If no data is entered, the process proceeds to step 129.

If the data input in step 106 is not a reservation recording selection, the process proceeds to step 112. If the reservation recording selection is performed, in step 107, the microcomputer 22 transmits the voice data to the voice signal generator 25 to generate a voice. For example, the reservation recording is ready by converting the signal to the channel, start time, end time, and so on. If there is no input of the reserved recording data for a predetermined time, the process proceeds to step 129, and if there is an input of the reserved recording data, the process proceeds to step 109 to store the data contents and to store the data contents. Transfers a voice signal indicating that the reserved recording is completed, and the microcomputer 22 outputs a high signal to the input selector 23 in step 111 to bring the input selection to the tuner position.

In step 112, the tone signal input by the external user is transmitted to the microcomputer 22 through the tone decoder 28, and it is determined whether the input tone signal is the message recording, and if not the message recording selection, the process proceeds to step 118. If the message recording option is selected, the process proceeds to step 113 where the voice prompting to leave a message after the beep is generated and the microcomputer 22 drives the deck unit 29 to record (REC) the message of an external user and generates a beeping sound. do.

In step 116, the voice signal transmitted through the signal transmission unit 27 determines whether there is a voice signal for a predetermined time, and if there is a voice signal, repeats step 116 until there is no voice signal for a predetermined time, and the voice signal for a predetermined time. If no, the deck unit 29 is stopped at step 117 and the process proceeds to step 129 to turn off the hook switch 24 and hang up.

In step 118, it is determined whether the tone signal inputted by the external user is the message search selection. If the message search is not selected, the process proceeds to step 128, and the guide voice of the selected error is transmitted to the external user, and the process proceeds to step 105. To determine whether there is a new data entry for a certain period of time. When the message search is selected in step 118, the microcomputer 22 stores the current counter, and in step 120, the index (INDEX-) operation through the deck unit 29 starts the tape. If the sensor is detected, the process proceeds to step 122 to determine whether it matches the stored counter by operating the speed FF. If the sensor does not match, the process proceeds to step 122 to operate the speed again and matches the stored counter. Proceeding to step 117, the deck unit 29 is stopped and the call is terminated through step 129.

If the start sensor is not detected in step 121, the VIS detection is determined in step 124. If the vis detection is not detected, the process proceeds to step 120. If the synchronization signal transmitted through the signal 30 is detected by the synchronization signal detection circuit of the video circuit unit 31, the process proceeds to step 120, whereby the index- (INDEX-) is operated again, and in step 126 If the synchronization signal is not detected through the synchronization separator 32, the process proceeds to step 127. If the voice signal is not detected through the A / D converter 33, the process proceeds to step 120. If-(INDEX-) is operated again, and the audio signal is detected through the A / D converter 33, the flow advances to step 125 to reproduce.

In step 129, the microcomputer 22 selects the input selection of the input selector 23 as the tuner position, and in step 129, the hook switch 24 is turned off to make the hook-off state to end the telephone call. .

3 is a flowchart of a search operation by direct operation of a video cassette recorder according to the present invention, in which an external user turns on the video cassette recorder power in step 151 to search for a recorded message in the home, and in step 152. If it is determined that the message retrieval key is input, if the message retrieval key is not input, repeat step 152 until the message retrieval key is entered. If the message retrieval key is input, the deck unit 29 is driven in step 153 to index- (INDEX). If the start sensor is detected in step 154, and the start sensor is not detected, the process proceeds to step 156. When the VIS signal is detected, the playback is performed. Proceeding to step 153, the index- (INDEX-) is operated.

In step 158, if the synchronization signal is not detected, the process proceeds to step 153. If the synchronization signal is detected, it is determined whether the audio signal is detected in step 159. If the audio signal is not detected, the operation proceeds to step 153. Proceeds to operate the INDEX- again, and if an audio signal is detected through the A / D converter 33, proceeds to step 157 to continue playback.

If the start sensor is detected in step 154, the process proceeds to step 155 to stop the deck 29 and finish.

As described above, the present invention solves the problem of interrupting the recording of a message to make a reservation recording while a conventional answering machine is equipped with an automatic answering phone function in a telephone reservation video cassette recorder. By making reservation recording, message recording and message retrieval at the same time, there is an excellent effect that no separate answering machine is required.
