<p>PROBLEM TO BE SOLVED: To provide the infrared ray remote control transmitter of little battery consumption suitable in the case that a battery is a power source by selecting a part of the plural infrared ray light emitting elements in the practically different transmission directions of infrared rays successively or at random along with time lapse and driving them so as to emit light. SOLUTION: This infrared ray remote control transmitter TX is provided with the battery and a microcomputer inside a case 9, provided with a human body sensor 8 on a front surface and provided with the plural infrared ray light emitting elements 1-7 on an upper side. Based on signals detected by the human body sensor 8, the infrared ray light emitting elements 1-7 are driven to emit the light. Among the light emitting elements 1-7, the light emitting element 4 at the center is turned obliquely upwards and the light emitting elements 1-3 on a left side are turned obliquely upwards and also set obliquely to the left side. The light emitting elements 5-7 on a right side are turned obliquely upwards and also set obliquely to the right side. They are successively selected and driven to emit the light along with the time lapse, the direction angle of the infrared rays from the remote control transmitter TX is enlarged and a system to be controlled is surely controlled.</p> |
