Abstract
An electromagnetic wave reception device includes: a input reception portion for detecting an input electromagnetic wave transmitted from a transmission terminal at a predetermined timing and receiving the input electromagnetic wave; a lock control portion for unlocking or locking a locking mechanism, according to the input electromagnetic wave received by the input reception portion; and a timing change portion for changing the timing at which the input reception section detects the input electromagnetic wave, according to time zones. This structure provides an electromagnetic wave reception device capable of not affecting the convenience of the user while reducing the power consumption in receiving the input electromagnetic wave transmitted from the transmission terminal (e.g. a remote controller).
