摘要 PURPOSE:To make it possible to transfer needed information to a pocket-bell holder by decoding, storing and displaying an information signal while operating a sound when an address output signal agrees with its own address number. CONSTITUTION:A signal from a base station is received via antenna 21 and demodulated into a base-band signal by demodulation circuit 24 by way of radio frequency part 22 and IF part 23, and its output is sent to address detection circuit 25. When an address output signal agrees with its own address number, sound generator 26 is put into operation and the output of demodulation circuit 24 is sent to information decoding circuit 37. Circuit 37 decodes an information signal and then stores its output in memory unit 38 while displays 39 it. Consequently, a communicator dials the address number and then information by a general telephone set to transfer the information needed to a pocket-bell holder.
