<p>PURPOSE:To allow an IR sensor to sense without rotatably driving it by a motor by condensing an IR rays to be irradiated from a human body sensing area where a human body exists, sensing the condensed rays by sensing means, and deciding a position of the body from its sensed result. CONSTITUTION:An IR rays to be irradiated from a human body sensing area 14 is condensed by condensing means 4 of left and right side IR sensors 2, 3, and detected by the sensors 2, 3. IR sense signals of the sensors 2, 3 are input to a deciding unit 10 through an amplifier 5, and an A/D converter 8. The unit 10 analyzes the input signal, and estimates a present position of the body from an analyzed result. A present time is counted by a timer 12, and human body detecting data and place are stored in a memory 11.</p> |
