Abstract

PURPOSE: To prevent a battery from being over consumed and reduce a leaking current by continuously sending an infrared-ray reactivation signal modulated to a microwave frequency and connecting a power source to the electronic circuit of a portable device in response to the signal of the portable device. CONSTITUTION: The reactivation signal is sent by a circuit 4 provided at a check point positioned at an entrance and in the circuit 4, at least one light emitting diode 4a or a component of equivalent constitution is built in. When photodiodes 1 and 12 receive the infrared-ray reactivation signal, impedance decreases to zero and the voltage at A is determined by the value of a leak register 11 and the value of a direct current which is supplied from the power source 6 and rectified by a constituent component 10. The impedance of the photodiode 12 decreases from a high value at the time of light nonemission to zero at the time of light emission. Then a unique function reduces a continuous leak current when no light is emitted. Consequently, the life of the battery in a badge can be prolonged.
