Description

[Detailed description of the invention] The present invention relates to a television receiver equipped with two screens so that two programs can be viewed at the same time, and by making the part that displays the sub-screen independent as a child TV,
To provide something that allows only a child television to be used as a portable television.

Hereinafter, the present invention will be described in detail with reference to the drawings showing one embodiment thereof.

1 to 3 show its structure, and FIG. 4 shows its electrical configuration, where A is a parent TV and B is a child TV.

As shown in FIG. 4, the parent TV A includes an antenna terminal board IA, a distributor 2, a tuner 3A, a channel selection control circuit 4A, a signal processing circuit 5A, an adjustment circuit 6A, a remote control circuit 7, a cathode ray tube 8A, A speaker 9A, a power supply circuit 10A, a power switch IIA, etc. are provided to operate as an independent television receiver.

Further, a channel selection control circuit 12 for controlling the channel selection of the child television B on the parent television A is also provided.

On the other hand, child TV B also has antenna IB, tuner 3B,
Tuning control circuit 4B, signal processing circuit 5B.

It is provided with an adjustment circuit 6B, a cathode ray tube 8B, a speaker 9B, a power switch IIB, etc., so that it can also operate as an independent television receiver.

In addition, child TV B has power cord 1 for AC power.
The cord reel 14 that winds up 3 and the operating power supply are connected to the parent TV A.
A switch 15 is provided to switch whether the power is obtained from the power source or from the own power cord 13.

The parent television A and the slave television B are provided with connectors 16A to 19A and 16B to 19B for electrically coupling them together.

As shown in FIG. 5, each pin 20 of the connectors 16A to 18A has only half an electrode part 20X and the rest an insulating part 20Y.
In addition, each socket of connectors 16B to 18B is composed of two electrodes 21X and 21Y, and when pin 20 is not inserted, electrodes 21X and 21Y are in contact with each other.
It is assumed that when the pin 20 is inserted, its electrode portion 20X contacts the electrode 21X.

Further, the slave television B is provided with a protrusion 22 so that the switch 15 can be changed over when the slave television B is coupled to the master television A.

Therefore, when parent TV A and child TV B are not coupled, child TV B operates independently using its own antenna IB, channel selection control circuit 4B, adjustment circuit 6B1, and power cord 13.

On the other hand, when the child TV B is connected to the parent TV A, the connector 16A is connected to the distributor 2 of the parent TV A.

Antenna input is supplied to the tuner 3B of child TV B via 16B, and connectors 17A, 1 are connected from the tuning control circuit 12 to the
The tuning control circuit 3B is controlled via pin 7B, and the adjustment circuit 6B or signal processing circuit 5B is controlled from the remote control circuit 7 via pins 18A and 18B.

Also, at this time, connectors 19A and 1 are connected from parent TV A to
Power is supplied to child TV B via 9B.

In this way, in this device, the parent TV A and the child TV B
It is possible to combine them and use them as a two-screen TV, or to separate them and use them independently.

When the two are combined, the child television B can be used for viewing alternate programs or as a VTR monitor, and when separated, the child television B can be used as a small portable television.

Of course, the child television B may be a color television or a black and white television.

Next, the specific structure of this device will be explained with reference to FIGS. 1 to 3.

First, on a part of the front of the housing 23 of the parent TV A,
Storage room 2 where secondary TV B can be detachably stored
4 is provided, and connectors 16A to 19A are attached to the rear surface thereof.

Further, a door 25 that can be opened and closed is provided at the front.

On the other hand, in order to make it easier to store the secondary TV B in the storage room 24, the upper rear surface of the cabinet 26 is formed into a curved surface, and a protective recess 27 is later provided in which the connectors 16B to 19B are arranged. Set up

A recess 28 is formed on the upper surface of the cabinet 26 so that the antenna IB does not get in the way during storage, and is mounted therein, and a handle 29 for carrying is also provided in the recess 30.

In addition, 31 is a handle for storing and taking out.

As described above, the television receiver of the present invention is equipped with a parent TV and a child TV that can operate independently, and the child TV can be detachably stored in a storage chamber formed as a part of the parent TV. Therefore, when the child TV is stored, it can be used as a sub screen to monitor the VTR for watching programs on the other side, and when the child TV is taken out, it can be used as an independent child TV. , we were able to obtain something convenient with a wide range of uses.
