Abstract

PROBLEM TO BE SOLVED: To enable a user to recognize accurately a battery residual capacity with a simple configuration due to the battery residual capacity of the battery which drives an LED being discriminated, based on a current flowing through the LED. SOLUTION: An LED 32 as a light-emitting element connects in series with a collector of a transistor(TR) 34 via a resistor 38. Then a current flowing through a series circuit consisting of the LED 32 and the TR 34 is given to an A/D terminal of a microcomputer 30. The microcomputer 30 discriminates the remaining capacity of a battery 36 according to the detected current. The obtained battery remaining capacity information is given to a base of the TR 34 with a code signal according to a key entry signal, and a remote control signal is sent to a remote control receiver.
