1 and 2 show an embodiment of a remote control device of the present invention, and FIG. 1 is a schematic explanatory view of the circuit thereof.
FIG. 4 is an arrangement view of a television and a remote control transmission device of the present invention, and an operation explanation diagram. The remote control transmission unit 1 has the necessary number of transmission switches 2 (using ICs) arranged in an orderly manner, which is similar to the conventional remote control transmission device of this type, and a battery, a transistor, a capacitor, etc. are required although not shown. Similarly, the components are arranged on the circuit. However, the remote control transmission unit according to the present invention is characterized in that a push button for switching each transmission switch 2 and a light emitting diode (LED) are not arranged on the circuit.

Next, as shown in FIG. 1, the electric switch section 3 is provided with four circuits of analog switches 4 using ICs. The number of the switches 4 can be freely increased or decreased depending on the number of TV channels used and the like. As shown in the figure, the analog switch 4 using an IC is connected to a required number of switches 2 among the transmission switches 2 of the remote control transmission unit 1 by a code 5. Of course, the number of electrical switches may be equal to the number of transmitting switches. Next, information (program) necessary for opening and closing the electrical switch section 3 is input to the computer section 6. The information includes necessary information such as channel number, broadcast time, and volume adjustment. The program broadcasts the set channel at the set time. Next, reference numerals 7 and 8 in the drawing denote codes, and the code 7 connects the respective transmission switches 2 arranged in the remote control transmitter 1 and the LED (light emitting body) 9 provided in the television. 8 is a code in which the computer 6 and each analog switch (4) of the electrical switch 3 are connected. Transmitting LED (light emitter) for transmitting optical carrier
Reference numeral 9 is provided in the vicinity of the light receiving section 11 of the television main body 10, and is configured to transmit the electric signal from the remote control transmitting section 1 to the light receiving section 11 as a light wave signal.

Since the present embodiment has the above-mentioned structure, the electric switch programmed from the computer section 6 through the code 8 when the time for programming in the computer section 6 arrives. The specific analog switch 4 of the section 3 is operated (closed), and then the electric signal is operated via the code 5 to operate the specific transmission switch 2 corresponding to the analog switch 4 provided in the remote control transmission section 1 ( Then, the optical carrier is transmitted (transmitted) from the transmission LED 9 to the light receiving section 11 by the electric signal via the code 7. In that case, the image of the television channel corresponding to the transmission switch 2 of the remote control transmission unit 1 can be seen.

As is clear from the above operation, the image of the programmed channel is continuously displayed during the programmed time period, or the light receiving unit 11 has a property of responding to stronger light, so that the transmitting LED is received by the light receiving unit. Since it is installed very close to 11, even if the general remote controller (remote controller attached to the TV) is operated to change the channel of the TV, the optical signal from the transmitting LED 9 works strongly on the light receiving unit 11. From the remote control attached to the TV 1
Since it acts on the light receiving unit 11 in preference to the second optical signal, the remote controller 12 does not receive the interference of the transmitted light wave. As for the interference preventing action of the remote controller 12, an A.G.C. circuit (automatic gain control) is attached to the receiving circuit (light receiving circuit) of the television so that a strong light wave is preferentially received. Therefore, by mounting the transmission LED 9 of the remote control device of the present invention close to the light receiving portion 11 as described above,
Since the remote control device of the present invention continuously transmits the light wave from the transmission LED 9 because of its configuration, the time interval for the light wave from the remote control 12 attached to the television to enter is extremely narrow and almost impossible. , Further send LED9
It is possible to more reliably prevent interference by increasing the light emission power (light emission power) of. Compu
It is natural that the image of the desired channel can be viewed by a general remote controller (remote controller attached to the television) except the time zone programmed in the terminal.

[0009]

Since the present invention has the configuration and operation as described above, it is possible to display specific information free of charge by using a pay or free TV installed in a business establishment such as a hospital, hotel, or company. When providing to hospitalized patients, guests, employees, visitors, etc., it is possible to completely block the interference of the LED light wave of the remote control attached to the TV during the programmed provision time and broadcast it. The effect is that the target image (information) can be automatically broadcast (provided) by the program input to the computer.
