Abstract: PURPOSE: A position searching system is provided to be capable of using permanently and of efficiently recording and managing working information. CONSTITUTION: A position searching system comprises a power processing part(16) which rectifies an externally supplied power so as to have stable current and voltage. A key input part(13) enables a user to select desired data and program, and a screen display part(11) displays a message according to an operating state. A magnetic field generator(8) generates a magnetic field to be transferred to the exterior. A wire communication part(15) transmits and receives data, and is connected to an external device. A transmitter part(9) converts coded information into an electromagnetic field to transmit the converted electromagnetic field to the exterior. An antenna coil part(7) receives a radio wave transmitted from the exterior.
