Description

[Detailed explanation of the invention] This invention is a magnetic recording and reproducing device (hereinafter referred to as VTR).
The present invention relates to a video signal recording and reproducing device having a built-in television tuner, and is particularly intended to simplify the operability when recording video signals.

In general, a VTR equipped with a television tuner has the function of not only recording television programs from the built-in television tuner but also inputting and recording video signals from a video camera or the like from an external signal input terminal. Figure 1 shows an external view of a VTR with a television tuner.
1 is the VTR body, 2 is the power switch, 3 is the operation switch for recording and playing the VTR, 4 is the channel selection button for selecting the channel of the TV tuner, 5 is the video signal and audio signal to the VTR body 1
6 is an input terminal for externally inputting an external signal consisting of a video signal and an audio signal to the VTR body 1, and 7 is an input terminal for selecting a signal from the TV tuner and an external signal from the input terminal 6 and supplying it to the VTR. This is the switch button to switch.

The case where signals are recorded by the VTR body 1 shown in FIG. 1 will be explained using the specific configuration diagram shown in FIG. 2. Television radio waves from the antenna 11 are input to the television tuner 1a via the antenna terminal 12, a desired channel is selected using the channel selection button 4, the signal is detected by the signal detection circuit 1b, and the signal is input to the a terminal of the switch 1c. . On the other hand, an external signal from the video camera 13 is inputted to the b terminal of the switch 1c via the input terminal 6. Therefore, when recording the signal from the television tuner 1a, if the switch button 7 is set to the [TV] side, the switch 1c is set to the a
side, and when recording an external signal from the video camera 13, set the switch button to the [camera] side, the switch 1c will be set to the b side, and the recording circuit 1
A signal is input to each of d. Therefore, by operating the ``record'' button of the operation switch 3, the external signal from the television tuner 1a or the video camera 13 can be recorded.

However, in the conventional example shown in Figs. 1 and 2,
When trying to record the signal from the TV tuner 1a, for example, select the desired channel [2] with the channel selection button 4 and operate the [Record] button of the operation switch 3, but the switch button 7 is not moved to the [Camera] side. If it is, switch 1c is connected to side b,
Therefore, the signal of channel [2] from the TV tuner 1a is not recorded, and the external signal from the video camera 13 is input to the input terminal 6, and the [record] button of the operation switch 3 is operated in an attempt to record this signal. However, if the switching button 7 was set to the [TV] side, the switch 1c was connected to the a side, so there was a drawback that the signal from the video camera 13 was not recorded.

In order to eliminate the above-mentioned drawbacks, a conventional method has been used in which the input terminal 6 is configured as a connection switch 14 instead of the changeover button 7, as shown in FIG. That is, when the signal line from the video camera 13 is not connected to the input terminal 6, the signal detection circuit 1
b is input to the recording circuit 1d via the connection piece 14a, the signal from the television tuner 1a is recorded, and when the signal from the video camera 13 is connected to the input terminal 6, the connection piece 14a of the connection switch 14
is open to the a side, and the signal from the video camera 13 input to the input terminal 6 is input to the recording circuit 1d and recorded.

However, in the method shown in FIG. 3, when recording the signal from the television tuner 1a, it is necessary to disconnect the signal line of the video camera 13 from the input terminal 6, which is troublesome. In particular, if you forget to disconnect only the video signal line and the audio signal line among the signal lines connected to the input terminal 6, the video signal from the television tuner 1a will be input to the recording circuit 1d. Since the audio signal from the television tuner 1a is not input to the recording circuit 1d, problems such as no audio signal being recorded have occurred.

The present invention aims to improve the above-mentioned drawbacks and provide a configuration that is easy and reliable to operate.

The configuration of the present invention will be explained below based on the drawings.
FIG. 4 is an external view of a VTR with a television tuner showing an embodiment of the present invention. Components having the same functions as those explained in the conventional example of FIG. 1 are designated by the same reference numerals. 8 is a camera mode button newly installed on the front panel. This camera mode button 8 is used to select an external signal from the video camera 13 input to the input terminal 6, and also has a display function. FIGS. 5 and 6 are concrete configuration diagrams thereof, and the same reference numerals indicate the same functions as those explained in FIGS. 2 and 3 of the conventional example.

In FIG. 5, television radio waves from an antenna 11 are transmitted to a television tuner 1 via an antenna terminal 12.
a, a desired channel is selected using the channel selection button 4, the signal is detected by the signal detection circuit 1b, and is input to the a terminal of the switch 15a.
On the other hand, a signal from the video camera 13 is inputted via the input terminal 6 to the b terminal of the switch 15a. The switch 15a is configured to be connected to the b side when the camera mode button 8 is operated, and to the a side when the channel selection button 4 is operated. Therefore, when a desired channel is selected with the channel selection button 4, the switch 15a is connected to the side a, and the signal from the television tuner 1a is input to the recording circuit 1d, and when the camera mode button 8 is operated, the switch 15a is connected to the side a.
5a is connected to the b side, and a signal from the video camera 13 is input to the recording circuit 1d.

FIG. 6 shows a specific configuration example in which a display function is added to the embodiment shown in FIG.
are display lamps, and 18 is a power source for lighting the display lamps 16 and 17, respectively. When the camera mode button 8 is operated, an external signal from the video camera 13 is input to the recording circuit 1d via the b terminal of the switch 15a, and
The display lamp 17 lights up through the b terminal of the camera to indicate that the camera is in camera mode. On the other hand, when a desired channel is selected using the channel selection button 4, the signal from the TV tuner 1a is input to the recording circuit 1d via the a terminal of the switch 15a, and the display lamp 16 is turned on via the a terminal of the switch 15b. The TV mode or selected channel is displayed.

As explained above, according to the present invention, the channel selection button and the video camera mode selection button are arranged on the same panel, and when the video camera mode selection button is operated, the external signal from the video camera input to the input terminal is output. The signal from the TV tuner can be recorded by selecting the desired channel using the channel selection button. Since all desired signals can be selected on the same panel in this way, operational errors are extremely rare and the effect is great.

Further, the effect will be even greater if the operation status of the button is displayed by a display lamp or the like in conjunction with the channel selection button and the video camera mode selection button.
