Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a television receiver that can be operated by remote control.

<Prior art and problems> Conventionally, in a remote control device for selecting stations from a distance, the transmitter also serves as an operating switch for the television receiver body.In a television receiver, the transmitter is attached to the television receiver body. Conventionally, when selecting channels, etc., a transmitter mounting recess 2 is provided in the front cabinet 1 of the television receiver as shown in FIG. A through hole 3 for mounting was provided. A transmitter 4 is removably provided in the transmitter mounting recess 2, and a receiver 5 is mounted in the receiver mounting through hole 3. When the transmitter 4 is attached to the mounting recess 2 for tuning etc., the light emitting element 6 of the transmitter 4
The emitted light is transmitted to a light receiving element 7 provided in a receiver 5.

For this reason, since the receiver 5 must be placed near the transmitter mounting recess 2, the installation position is restricted, which imposes restrictions on the design.

In addition, the applicant of the present application previously filed the application filed in 1983-
In the device proposed in No. 17342 (see Utility Model Application Publication No. 119372/1983), as shown in FIG. 2, the light receiving element 7 is provided separately from the receiver 5, and one end of the flexible optical fiber 8 is The optical fiber 8 is arranged close to the light-receiving element 7, and the other end is branched into two within the receiver 5, with each end facing in the direction of receiving the light. The signal is then transmitted from the receiver 5 to the light receiving element 7 for channel selection and the like.

For this reason, a plurality of optical fibers 8 are used to transmit a sufficient amount of light for operation, resulting in poor working efficiency and the risk of malfunction.

<Purpose> The present invention aims to eliminate the drawbacks of the conventional devices and provides a remote control device for a television receiver that has a simple configuration and can transmit a sufficient amount of light for operation.

<Embodiment> An embodiment of the device of the present invention shown in FIG. 3 will be described below.

In the device of the present invention, as shown in FIG. 3, a transmitter mounting recess 10 into which a remote control transmitter 4 is detachably mounted is provided at an arbitrary location on the front cabinet 9 of the television receiver body. A remote control receiver 5 having a light receiving element 7 for receiving light emitted from a light emitting element 6 of the television receiver 4 is provided at an arbitrary location in front of a front cabinet 9 of the television receiver body. The light emitted from the light emitting element 6 of the remote control transmitter 4 is transmitted between the transmitter mounting recess 10 and the remote control receiver 5 to the light receiving element 7 of the remote control receiver 5.
They are connected by a transparent pipe 11 made of acrylic or the like for transmission.

In the above configuration, the remote control transmitter 4
the front cabinet 9 of the television receiver body.
When the remote control transmitter 4 is installed in the transmitter mounting recess 10 to perform operations such as tuning, the light emitted from the light emitting element 6 of the remote control transmitter 4 passes through the pipe 11 and reaches the light receiver provided in the remote control receiver 5. The signal is transmitted to element 7.

In this case, the cross-sectional shape of the pipe 11 may be of any shape, but as shown in FIG. The transmission effect can be increased by pasting or coating a reflective substance.

<Effects of the Invention> As stated above, the present invention provides an optical wireless remote control transmitter that is removably attached to the transmitter mounting part of the television receiver body, and the operating switch of this transmitter can be used for normal operations such as tuning. In a remote control device for a television receiver that also serves as a television receiver, the transmitter mounting portion and the remote control receiver are connected by one rigid light guide (for example, a transparent pipe), and the remote control transmitter is connected to the transmitter mounting portion and the remote control receiver. When the remote control transmitter is attached to the transmitter mounting section and operations such as tuning are performed, the light emitted from the remote control transmitter is reliably transmitted to the remote control receiver via the light guide, which improves television image reception. There is no risk of malfunction due to light generated inside the machine body being picked up, and the light guide is easy to install.

Furthermore, the remote control receiver can be installed anywhere on the front of the television receiver body, and the remote control transmitter mounting part can be placed anywhere on the television receiver body without being restricted by the position of the remote control receiver. Since it can be placed anywhere, the degree of freedom in designing the external appearance of the product increases.
