Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an electric configuration of an answering machine part of a video tape recorder having an answering machine function according to the present invention.

In the figure, the video tape recorder body (hereinafter referred to as VT
Abbreviated as R body. 1) a microcomputer section 2 for controlling the overall operation and managing and executing answering machine reservation data, and a controlled section (including a recording section, a motor drive section, etc.) 3 controlled by the microcomputer section 2. And an AC control unit 4 that is turned on / off by a microcomputer unit 2 at a recording start time and a recording end time based on the answering reservation data. These configurations are the above-described conventional answering system of a video tape recorder. The configuration is the same.

In addition, the video tape recorder body 1 includes an external device 9.
A remote control signal storage unit 5 for receiving a remote control signal from a remote control switch (not shown) for remote control of and analyzing the received remote control signal, and storing the remote control signal storage unit 5 sequentially corresponding to assigned command Nos. And a remote control signal generator 6 for reading out the remote control signal stored in the remote control signal 5 and converting it into the original remote control signal. The remote control signal storage 5 and the microcomputer 2 are provided. Are two-way connections. Also, the remote control signal storage unit 5
The remote control signal generator 6 has a bidirectional connection. The remote control signal output from the remote control signal generation unit 6 is transmitted by the remote control signal transmission unit 7 to the remote control signal reception unit 8 of the external device 9. Here, the remote control signal transmitting section 7 emits the same infrared signal as the remote control signal transmitted from the remote control switch of the external device 9 toward the remote control signal receiving section 8 of the external device 9. However, the remote control signal transmitting unit 7 and the remote control signal receiving unit 8 of the external device 9 may be connected by wire, and a remote control signal may be transmitted to the remote control signal receiving unit 8 of the external device 9 via this signal line. It is possible.

In addition, the AC control unit 4 of the VTR 1
The line is connected, and the power supply of the external device 9 is controlled to be on / off depending on the state of the AC control unit 4.

The user first reads the remote control signal of the external device 9 to be linked with the VTR into the remote control signal storage unit 5.
The remote control signal storage unit 5 analyzes the read remote control signals, assigns command numbers in reading order, and sequentially stores them in a predetermined storage area.

On the other hand, in the microcomputer unit 2, answering reservation data is registered in advance by a user's key input operation. In the answering machine reservation data, the command number stored in the remote control signal storage unit 5 can be registered together with the VTR recording data (recording start time and recording end time or recording time, data of recording channel, etc.). Thus, the user registers, for example, channel data of a menu for which the user has made an answering machine reservation by designating a command No.

The microcomputer unit 2 performs control according to the registered answering machine reservation data. That is, when the recording start time at which the message recording is reserved, the control signal is first sent to the AC control unit 4 in accordance with the recording data in the message recording data,
The control unit 4 is turned on. Thereby, the power of the external device 9 is turned on. Further, the microcomputer unit 2 controls the controlled unit 3 according to the recording data in the answering machine reservation data, and sends the registered command No. to the remote control signal generation unit 6.

The remote control signal generation unit 6 reads out a remote control signal with a corresponding command number from the remote control signal storage unit 5 based on the command number input from the microcomputer unit 2 and converts the read remote control signal into the original remote control signal. The signal is output to the remote control signal transmitter 7. The remote control signal transmitting section 7 transmits the remote control signal to the remote control signal receiving section 8 of the external device 9. In the case where the remote control signal received by the remote control signal receiving unit 8 is a channel switching instruction signal, the external device 9 performs channel switching according to the instruction.

In this way, the recording on the VTR main body 1 is performed, and the channel switching of the external device 9 is also performed.

(Effect of the Invention) Since the video tape recorder having an answering machine function of the present invention is configured to store the remote control signal of the external device together with the answering reservation data, the remote control of the external device becomes possible. In addition to the conventional control of only turning on / off the power, a plurality of operation processes such as a channel selection operation can be linked with each other, so that an answering function using an external device can be expanded.
