PURPOSE:To improve more the general-purpose performance and multi-function by providing a means reading one data code corresponding to key input information from a storage means and combining one read custom code and one data code and sending a remote control signal. CONSTITUTION:A CPU 24 controls the entire equipment according to the control program in a ROM 34. A keyboard interface 26 generates a key scan signal to fetch the key input information from a keyboard 12 and the information is sent to the CPU 24. A timer circuit 28 is used for the time control of the entire system. A remote control transmission circuit 30 reads a custom code and a data code from the CPU 24 and modulates them by using a frequency signal having a frequency of nearly 40kHz generated from a ceramic oscillator 20, that is, a carrier signal and an infrared-ray remote control signal is sent from a light emitting diode 16. Thus, general-purpose performance or multi- function is provided. |
