PURPOSE:To simplify the constitution and to improve the versatility by constituting an interface device between a computer device and an electronic device with a printer parallel port of the computer device. CONSTITUTION:When a remote control command is received from a personal computer together with a synchronizing output STB signal as printing data, a timing circuit 26 is triggered with the STB signal and a code converting circuit 21 is made active. Then, a BDC-decimal decoder 21b converts the code of the print data based on an address data designated with the printing data from an ROM IC21a. A remote control code corresponding to the command is generated in a remote control transmission IC based on the signal obtained through the conversion. Furher, when a time sufficient for the transmission of the remote control code is elapsed, the circuit 26 is inverted to the original state to make the circuit 21 inoperative, allowing to receive the next data. |
