[0004]

However, in the conventional configuration as described above, the signal of the output terminal of the magnetic recording / reproducing apparatus of this unit is input to the external input terminal of the receiver, and the output terminal of the receiver is connected to the output terminal of the unit. When the input is input to the dedicated input terminal, the external input is selected on the receiver, and when the dedicated button is pressed, the dedicated input terminal is selected by the input switching unit, so that there is no signal source.
Therefore, from the output terminal of this unit through the external input of the receiver,
There was a problem that it was not possible to record a broadcast program that was visualized. Further, there is a problem that recording is continued even if the signal from the receiver is lost halfway.

The present invention solves the above-mentioned problems of the prior art. When recording a broadcast program which is received and visualized by the receiver, a signal from the output terminal of the receiver is pressed by pressing a dedicated button. Only when there is a signal visualized on the receiver by inputting through the dedicated input terminal, detecting the presence or absence of a signal during recording and recording, and switching the input switching to the receiving section if there is no signal for a certain period and stopping recording. It is an object to provide a magnetic recording / reproducing device capable of recording.

[0006]

To achieve the above object, a magnetic recording / reproducing apparatus of the present invention comprises a dedicated input terminal for inputting a signal from an output terminal of a receiver, a receiving section for receiving a broadcast program, An input switching section for switching the input of the dedicated input terminal and the receiving section, a signal detecting section for detecting the presence or absence of the signal selected by the input switching section, and a recording / reproducing for recording the signal selected by the input switching section. Section, a display section indicating that the dedicated input terminal or the receiving section is selected in the input switching section, a power source for each section is turned on, a recording start command is sent to the recording / reproducing section, and the input switching section is dedicated to the dedicated section. It has a signal no-period detector that switches to the input terminal and inputs the signal presence / absence data of the signal detector during recording / recording to detect the absence of a signal for a certain period of time. A control unit for sending the recording stop command to the parts side with switching the recording and reproducing unit, and a magnetic recording and reproducing apparatus having a dedicated button to start the operation of the control unit.

[0007]

With the above structure, when the dedicated button is pressed, the input switching section connects to the dedicated input terminal. At this time, the signal detector detects the presence or absence of a signal from the dedicated input terminal,
When there is a signal, the video signal from the output terminal of the receiver is recorded. However, when there is no signal, the control unit switches the input switching unit to select the receiving unit side of the unit. Therefore, the signal received by the receiving unit of this unit is visualized from the output terminal through the external input terminal of the receiver, and the signal of this broadcast program can be easily recorded without error.

Further, while the signal from the output terminal of the receiver is being input through the dedicated input terminal by pressing the dedicated button, if there is no signal for a certain period, the input switching unit switches to the receiving unit to stop recording. Then, it can be recorded only when there is a signal visualized by the receiver.
