DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS. The television set body 1 of the television set of the present invention is provided with a small screen 4 composed of a liquid crystal panel 3 separately from the main screen 2 as shown in FIG. Specifically, a recess 5 for mounting the liquid crystal panel 3 is formed at the position of the small screen 4 of the television set main body 1 as shown in FIG. In the state where the liquid crystal panel 3 shown in (b) is mounted, the electric contacts 6 on the side of the concave portion 5 and the electric contacts 7 on the side of the liquid crystal panel 3 come into contact with each other, so that the information on the small screen can be monitored on the liquid crystal panel 3. .

As shown in FIG. 3, a remote control main body 8 of a remote control device for remotely controlling the television set main body 1 has an engaging portion 9 as connection means to which the liquid crystal panel 3 can be mounted. When the liquid crystal panel 3 is mounted on the joint 9 as shown in FIG. 4, the electric contacts 10 on the remote control main body 8 and the electric contacts 7 on the liquid crystal panel 3 come into contact with each other, and the information of the remote control main body 8 is transmitted. It can be monitored on the liquid crystal panel 3.

The liquid crystal panel 3 of this embodiment is similar to that of FIG.
As shown in FIG. 1, a half mirror 13 is provided between the rear panel 11 and the polarizing plate 12. As shown in FIG. 6, a backlight 14 is incorporated in the TV set main body 1. When the liquid crystal panel 3 is mounted on the TV set main body 1, the liquid crystal panel 3 is illuminated with light P of the backlight 14 so that the liquid crystal panel 3 is of a transmissive type. To display information.

Further, as shown in FIG. 7, the TV set main body 1 has a built-in FM wave transmitting circuit 16 for transmitting the signal of the channel tuner 15 to the remote control main body 8 as an FM-modulated radio signal. F on the remote control body 8 side
An FM wave receiving circuit 17 for receiving and demodulating a signal from the M wave transmitting circuit 16 is incorporated.

With such a configuration, when the liquid crystal panel 3 is mounted on the remote control main body 8, the FM wave transmitting circuit 1
6 can be received and demodulated by the FM wave receiving circuit 17 and the small-screen video can be monitored on the liquid crystal panel 3 on the remote control device side, and the small screen can be monitored at hand. It is easier to see than when monitoring the small screen of the set body 1. In addition, by transmitting not only the video signal but also the audio signal from the television set main body 1 side and reproducing the same on the remote control main body 8, a small-screen channel can be used without using an earphone or the like. Can be heard, and the broadcast contents of the small screen can be easily understood.

In this embodiment, since the remote control body 8 is not provided with a backlight, the screen of the liquid crystal panel 3 receives light from the front and operates as a reflection type as shown in FIG.

FIGS. 9, 10 and 11 show another embodiment in which a backlight is provided in the remote control device. In the embodiment shown in FIGS. 9A, 9B, and 9C, the backlight 18 is detachably provided on the back side of the liquid crystal panel 3 mounted on the remote control main body 8, and the backlight 18 is mounted. In this state, the small screen can be monitored in a transmission type.

In the embodiment shown in FIGS. 10 (a), 10 (b) and 10 (c), a backlight 18 is rotatably supported on the remote control main body 8 by a shaft S, as shown in FIG. 10 (b). In this state, the small screen can be monitored in a transmission type.

In the embodiment shown in FIGS. 11A and 11B,
The backlight 18 is built in the remote control main body 8 so as to be able to move back and forth, and as shown in FIG.
When the backlight 18 slides out and projects, the small screen can be monitored in a transmission type.

FIG. 12 shows another application of the remote control device of each of the above embodiments. Here, an example of the remote control device shown in FIG. 10 will be described, but the same applies to other remote control devices.

As shown in FIG. 12, when the backlight 18 is turned to a position where it is not used and the liquid crystal panel 3 of the remote control device is set on the projector 19, the small screen received from the TV set main body 1 is enlarged. Can be projected. 20 is a lamp as a light source, 21 is a condenser lens, 2
2 is a mirror and 24 is a projection lens.

In each of the above embodiments, the information of the small screen channel is transmitted from the television set main body 1 to the remote control main body 8 by radio. However, it is also possible to transmit the information by wire.

[0019]

As described above, according to the television set with a remote control device of the present invention, there are provided a television set main body having a small screen different from the main screen, and a remote control device for operating this television set main body. The small screen is constituted by a liquid crystal panel detachable from the television set main body, and the remote control device is provided with connection means for attaching and detaching the liquid crystal panel detached from the television set main body, and the remote control device is attached to the remote control device. Because it was configured to monitor information on the LCD panel,
The contents of the back program or video can be confirmed at hand, and the small display size allows reliable recognition of information such as fine characters.
