Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a home VTR, for example.
The present invention relates to a recording / reproducing apparatus such as the above, and particularly to a current mode display and an operation message display of this apparatus.

[0002]

2. Description of the Related Art Recently, many VTRs have a plurality of input sources for recording. For example, in the case of a model equipped with a BS tuner (satellite broadcast tuner), the output of the BS tuner can be viewed on the monitor display device while recording the reception signal of the terrestrial tuner such as VHF broadcast or UHF broadcast. . Therefore, it is uncertain whether or not the screen displayed on the monitor display device is necessarily the screen of the source during recording of the VTR.

Conventionally, in this case, the user himself or herself confirms which source is being monitored by the monitor display device based on the input selection state by the character display on the monitor display device and the input selection state of the VTR. .

Further, conventionally, when an operation by the user is incorrect, an operation error is notified to the user, and an alarm sound for that purpose is issued or an error message is displayed on a liquid crystal display. It is being appreciated.

[0005]

As described above, in the case of the conventional VTR with the BS tuner, the user can confirm whether the image displayed on the monitor display device is a ground wave or a satellite broadcast wave. It was troublesome because it had to be recognized from the input selection state of the monitor display device and VTR.

In addition, a plurality of VTRs are provided in one housing.
A recording / reproducing apparatus provided with a unit has been proposed (Japanese Patent Laid-Open No. 61-61160
No. -80583), for example, a device provided with two VTR units is called a so-called double deck VTR.
In this double-deck VTR, the possible modes become very complicated. For example, there are simultaneous playback of different sources, simultaneous recording, a mode in which internal VTR units are connected to each other, and the like. Therefore, it is difficult for the user to confirm what mode each VTR unit inside is currently in.

Further, in the case of a method of notifying an operation error of the user by an alarm sound or an error message, if the user does not recognize the operation button position of the recording / reproducing apparatus, the content of the warning may not be understood. is there. Moreover, simply
Since only a warning is issued, the user must determine for himself how to make a correct operation input.

In view of the above points, the present invention is a recording / reproducing apparatus in which even a user unfamiliar with the apparatus can easily recognize the state of the current mode, and can easily confirm the operation error and the next correct operation. The purpose is to provide.
