y) 15 and input means 13 for inputting the control program and control data.

FIG. 5 is a block diagram of the central processing section 2'' of FIG. 4. When a desired key of the key operation section 5 is pressed, for example, the key for selecting a television channel "1", an operation signal corresponding to the operation is input to the key input multiplexer 17 of the central processing section 2', and a binary number is generated. and processed by the arithmetic logic circuit 18. This process is performed according to a program written in the internal ROM 19. That is, the internal ROM 19 has data for comparison with respect to the input, and the arithmetic logic circuit 18 compares the input data with the data in the internal ROM 19 to determine key manual data.Based on the result, the data in the internal ROM 19 is Execution data according to the program is input to the counter/register section 2.degree., and is further output to the display panel 23 via the data latch type 7-rip 70-tube 21 and shift register 22. This display panel 23 is, for example, an LED or the like, and displays the character "1" indicating channel selection.

Processing data from the arithmetic logic circuit 18 is applied as serial data to the output drive circuit 3 via a data latch type 7 lip 70 tube 24 and a shift register 25. This output drive circuit 3 performs amplification and waveform shaping, and provides the light to the light emission output section 4 . Control data is transmitted from the light emission output section 4 to the electronic device to be controlled. In this embodiment, the channel of the television receiver is set to "1" by the light.

The remote control device of the present invention includes an input means 13 for inputting a control program and control data individually corresponding to an electronic device to be remotely controlled, and a control program and control data from the input means 13 are written. RWM is a writable/readable memory
(Read-Write-Memory) 26 is provided, and when adding a new electronic device to be controlled, a control program and control data corresponding to the electronic device are inputted from the input means 13. Write the control program and control data to the RWM26, and
The electronic equipment is controlled using the WM 26.

To externally input a control program and control data corresponding to this new electronic device, connect the program in the internal ROM 19 to the program/data input routine by switching the mode selector switch 16 to the program/data input mode. do. At this time, rPRo-LJ (7' program load) or the like is displayed on the display panel 23. Further, the input date 27 is placed in a standby state based on the input mode. In this example,
A control program and control data corresponding to the new electronic device are recorded on a magnetic card 28 as shown in FIG. FIG. 6 shows a magnetic card 28 on which program data for, for example, an air conditioner as a newly added electronic device is written. This magnetic card 28
By sliding the inside of the input means 13 as will be described later, program data for control is input to the remote control device. This magnetic card 28 has data recorded in two columns along the longitudinal direction (horizontal direction in FIG. 6). The data 28a in the upper row is reference timing data, and the data 28b in the lower row is program data to be input.

The data is once written into the RWM 26 via the shift register 29.

In this embodiment, an external non-volatile RWM 15 is provided, and when the input of program data is completed, the internal ROM is
The data in RWM 26 is checked according to the program in 19, and the arithmetic logic circuit 18 and counter register unit 20 are checked.
The program is then written to the air conditioner program storage position A of the external non-volatile RWM 15. As a result, the input control program and control data will not be lost even if the power is turned off. When the writing operation is completed, A, which indicates the storage position of the air conditioner, is displayed blinking on the display panel 23, and the mode changeover switch 16 is ready for operation.

Next, the mode switching switch 16 is switched to the normal control mode, thereby making it possible to remotely control the newly added air conditioner.
