PURPOSE: To provide an information communication equipment having a simple constitution which doesn't receive the communication from another transmitter and doesn't become. a disturbing wave and doesn't have a special channel selecting function added. CONSTITUTION: Print information from a personal computer 1 is temporarily stored in a first memory through a microcomputer 2 on the transmission side. At this time, the number of a printer 17 to which information should be sent is inputted from the personal computer 1 by key operation. Thus, the microcomputer 2 on the transmission side makes a PN code generator select a PN code to be generated. Then, print information stored in the first memory 3 is successively read out and is subjected to spectrum spread in a spread spectrum modulator through a base band modulator 4 and is sent from an antenna 7 on the transmission side. A spread spectrum demodulator receives it to perform inverse spread only in the case of coincidence with a PN code incorporated in a synchronising circuit 13, and print information is outputted from a printer 17 through a base band demodulator 14 and a microcomputer 15 on the reception side. |
