SUMMARY OF THE INVENTION According to the present invention, a transmitter which emits an infrared remote control signal by a key operation and a light receiving portion composed of a plurality of light receiving elements receive the remote control signal and convert the received remote control signal into an electric signal. The signal processing unit amplifies and detects the waveform, and then the waveform is shaped and input to the CPU. The CPU soft-processed so that the waveform-shaped signal can be read reads the operation command content of the remote control signal and the remote control signal for each manufacturer. The data for each maker corresponding to the operation command content is sequentially read from the memory unit that stores the data as a data, and the remote control signal generation unit sequentially generates the remote control electric signal for each maker based on the data. At the very least, an infrared remote control signal based on the remote control electric signal is sequentially emitted from a light emitting section composed of a plurality of light emitting elements. There is provided a multi-remote controller system configured with the remote control signal converting unit you.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A multi-remote control system according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of essential parts showing an embodiment of a multi-remote control system according to the present invention. In the figure, reference numeral 1 denotes a transmitter which comprises a key operation unit 2, a remote control signal generation unit 3 and a light emission unit 4, and which emits an operation command signal and a manufacturer designation signal based on a user's operation as a remote control signal 5 consisting of a dedicated code, Reference numeral 6 comprises a light receiving section 7, a signal processing section 8, a memory 9, a CPU 10, a remote control signal generating section 11 and a light emitting section 12, which receives the light emitting signal 5 and sequentially converts it into an operation command signal for each designated maker and sequentially. The remote control signal conversion unit emits a remote control signal 13.
The transmitter 1 in the present invention is not an independent device but is paired with the remote control signal conversion unit 6, and uses a unique code. The infrared transmission system between the transmitter 1 and the remote control signal conversion unit 6 is based on the system conventionally implemented in a color television receiver or the like. Generally, an infrared signal is composed of a reader code, a custom code (including inverted code), a data code, a continuous code, and the like, and each of these codes is specified and transmitted / received. By doing so, the remote control signal converter 6 that receives the light emission signal 5 from the transmitter 1 can determine the content of the operation command.

Next, the operation of the present invention will be described. The key operation unit 2 is provided with operation keys and a manufacturer-specified key that are frequently used when operating a television, a VTR, a video disc, or the like. The operation keys are, for example, power on / off, channel button, volume, reproduction of video equipment, recording, fast forward, rewind, stop and the like. The manufacturer designated key is for generating only a designated signal from the stored manufacturer. FIG. 2 shows an example thereof. Based on the key operation, the remote control signal generator 3 generates an electric signal composed of the above codes, and the light emitter 4 emits infrared light. The code of the light emission signal from the light emitting section 4 is different from the code emitted from the light emitting section 12. This is to prevent a malfunction caused by a light emission signal from the light emitting unit 12 entering the light receiving unit 7 due to reflection or the like. The light emission signal 5 is received by the light receiving unit 7. The light receiving section 7 is composed of a plurality of light receiving elements (21 to 24) [light emitting elements (25 to 28)
The same]. This is done to enable reception of light from multiple directions and emission of light in multiple directions, that is, the transmitter 1
This is to expand the local use range of. Therefore, the remote control signal converter 6 is installed on the ceiling, wall, or the like. FIG. 3 shows an example of installation on the ceiling. Then, the light receiving element (21 to 2
4) and the light-emitting elements (25 to 28) are appropriately arranged on, for example, a hemispherical surface so that light reception and light emission can extend in multiple directions.
The signal 31 converted from light to electricity in the light receiving portion 7 is amplified, detected and waveform shaped in the signal processing circuit 8 and input to the CPU 10 (32). Here, the CPU 10 determines the content of the operation command and the designated manufacturer. On the other hand, since the operation instruction data for each maker is stored in the memory section 9, the CPU 10 reads out the corresponding data from the operation instruction content from the signal processing section 8 and the maker designation signal from the memory section 9 (33). .. If there are multiple designated manufacturers, they are read sequentially. The CPU 10 inputs the read data to the remote control signal generator 11 (34). The remote control signal generation unit 11 generates a remote control electric signal 35 that matches the code of the designated manufacturer and causes the light emitting unit 12 to emit light. When there are multiple designated manufacturers, light is emitted sequentially. Light emitting part 12
As described above, since it is composed of a plurality of light emitting elements, the light emission is in all four directions, and it is not necessary to centralize the positions of the devices (14 to 16) that receive the light.

[0008]

As described above, according to the present invention, a single dedicated transmitter can operate a plurality of devices of different manufacturers, and the dedicated transmitter can be used in a wide range of locations. Since it is not necessary to collect all the devices in one place, the usability of the system is improved, which is a great advantage.
