Description

[Detailed Description of the Invention] The present invention relates to a television receiver that can be operated by remote control (hereinafter abbreviated as remote control).

Conventionally, a remote control transmitter has been removably installed on the front of the television receiver, allowing not only remote control operation from a distance, but also when the transmitter/receiver is housed in the receiver, also serving as an operating switch for the transmitter. Television receivers that can perform various operations such as turning on and off stations and power have been proposed, and some of them have been commercialized.

In this kind of conventional television receiver, as shown in FIG. 1, a transmitter storage recess 2 is formed in the front cabinet 1 of the receiver body, and a through hole 3 for installing a receiver is bored in the storage recess. 2, a remote control transmitter 4 is detachably attached thereto, and a remote control receiver 6 having a built-in light receiving element 5 is attached to the through hole 3.

Furthermore, operation switches 7, 7, . It had 9 built-in.

In the above-mentioned television receiver, the first
As shown in the figure, with the remote control transmitter 4 housed in the storage recess 2, the operation switches 7, 7, . . . are operated as appropriate to select a channel.

In the case of 2, optical information such as channel selection emitted from the light emitting element 9 is transmitted through a window hole 1 formed in the side surface of the light transmitting part 8 and the remote control receiving part 6.
0 and was directly transmitted and received by the light receiving element 5.

On the other hand, when operating the remote control, when the remote control transmitter 4 is removed from the storage recess 2 of the receiver body and the transmitter 4 is operated from a distance toward the receiver body, optical information emitted from the light emitting element 9 is transmitted to the front of the receiver 6. The light is received by the light emitting element 5 through a window hole 11 drilled in the channel, and operations such as channel selection are performed in this way.

However, with conventional television receivers such as those mentioned above,
In addition to operating the remote control, when the remote control transmitter is housed in the receiver body, it also serves as the operating switch for the transmitter, so the light receiving element 5 of the remote control receiver 6 is connected to the transmitter housing provided on the front of the receiver body. It had to be placed near the recess 2, its installation position was restricted, and the light receiving element 5 had to receive optical information from two directions, which inevitably resulted in a decrease in reception sensitivity.

The present invention has been devised in view of these points, and it is an object of the present invention to provide a television receiver that eliminates the above-mentioned drawbacks.

In particular, the present invention provides a television receiver that can reliably transmit optical information to a light receiving element using optical fibers and is not limited to the installation location of the light receiving element.

The present invention will be described below according to embodiments shown in the drawings.

FIG. 2 shows one embodiment of the present invention, in which the same parts as in FIG. 1 are given the same reference numerals.

Here, the light receiving element 5 is separated from the remote control receiving section 6, attached to a desired board 12 such as a channel selection circuit board, and electrically wired together with other circuit components.

Then, using a plurality of flexible optical fibers 13, one end surface of the fibers 13 is arranged close to the light receiving element 5, and the other end is branched into two parts within the remote control receiving section 6, and each end surface is opened into a window. It is placed in the hole 10°11.

Therefore, in the above-mentioned television receiver, when operating the remote control, by pointing the remote control transmitter 4 toward the remote control receiving section 6 of the receiver body, optical information such as channel selection etc. emitted from the transmitter 4 can be transmitted. is incident on a part of the optical fiber 13 through the window hole 11, and the fiber 13
is guided to the light receiving element 5 at the other end.

On the other hand, the remote control transmitter 4 is placed in the storage recess 2 as shown in FIG.
, the optical information emitted from the transmitter 4 enters the remaining end face of the optical fiber 13 through the window hole 10 and passes through the fiber 13 to the light receiving element
guided by.

According to the present invention, in a television receiver in which a remote control transmitter is detachably attached to the front surface of the receiver body and the operation switch of the transmitter is also used for normal channel selection, etc., one end of an optical fiber is attached to the remote control receiver. Since the optical information is guided to the light-receiving element through the fiber, the light-receiving element can be placed away from the front of the receiver main body and at any desired position, such as on the channel selection circuit board.

In this case, if one end of the fiber is separated and placed near the light emitting part of the stored transmitter, the remote control receiving part can be installed at a position separate from the transmitter storage part.
Furthermore, when the transmitter is stored, the optical information is reliably input into the fiber and transmitted to the light receiving element.
