PURPOSE:To send a code as a wireless signal to an electric product to be controlled by providing an input means receiving a prescribed command signal a storage means, an analysis means, a code generating means and a transmission means sending the generated code in a wireless way. CONSTITUTION:When one byte of an input command signal is sent together with a strobe signal from a personal computer main body 6, the signal is latched in a latch circuit 10 through a printer connector 7. A flip-flop circuit 11 is set by the same strobe signal at the same time and returned to the personal computer main body 6 as a busy signal to apply interruption to an interruption terminal of the microcomputer 12. The command signal is stored in the internal RAM of the microcomputer 12 and converted into a wireless signal corresponding to the command signal from the port P21 finally, impressed to a transistor 14 and converted into an optical signal from a light emitting diode 15. Thus, the direct control of the electric product is controlled directly by using the personal computer.
