Title:
REMOTE CONTROLLER FOR HOUSING EQUIPMENT
Document Type and Number:
Japanese Patent JP2705487
Kind Code:
B2
Abstract:
PURPOSE: To achieve longer life of a battery power source by optimizing an operation of supplying a power source to a transmitting/receiving means to reduce a circuit current while a radio wave signal emitted from other sources is detected to prevent possible collision.
CONSTITUTION: When a wireless radio wave signal is transmitted to a housing equipment from a remote controller, a receiving means 1 is operated to check the vacancy of a communication circuit. At the same time, a transmitting signal generating section 6 is operated to put the operation on a standby position. Then, after the checking of the vacancy of the communication circuit, a power source of the receiving means 1 is turned OFF while an output amplifier 7 is actuated to emit 2 transmission signal to an antenna 4.
