PURPOSE:To make a radio calling device possible which calls each individual to function to itself and also to its peripheral equipments by making the calling device react alone a radio call signal with no pocket bell attached to an information equipment and then transmit the information to the information equipment main body with pocket bell attached to the information equipment. CONSTITUTION:The radio wave received by a built-in antenna 5 is amplified by a radio wave receiving part 6 and then converted into a digital signal. Then this digital signal is processed by a signal processor 7 and temporarily stored in a buffer 8, and a CPU 9 decided whether the desired information is obtained or not. That is, the CPU 9 drives a gate array 12 when cell information is coincident with the identification information on the person who is carrying the calling device with him. Then a signal is transmitted to a connector 13 of a credit card size and then interrupted to the information processor main body. Then the power of a battery 15 is supplied to a power switching device 14 as long as the device 14 is attached to a radio calling device. The CPU 9 is instructed to receive a radio call signal. If this call signal is not effective, an interruption signal IRQ is produced. |
