PURPOSE: To attain information communication with high security by displaying selectively transmission information. CONSTITUTION: A radio signal is demodulated by a reception section 2 via an antenna 1, converted into a digital signal by a decoder 3 and destination ID information representing a data transmission destination and ID information stored in an ID ROM 4 are collated. When they are coincident, it indicates that the signal is addressed to itself, then a control section 5 stores data to a RAM 8, and simultaneously an incoming call is sounded by a speaker 10 and an LED 11 is blinked. A message generated by itself, names of persons, and telephone numbers or the like are stored in a RAM 8 as a data bank, and data set to be non-displayed data in the data of the data bank are used for secret data. The data in the data bank and the secret data are quoted when they are displayed on a display section 9 by allowing a sender to send the collation data. When the secret data are quoted partly or as a whole, the secret data are not displayed on the display section 9 but other prescribed contents are displayed. |
