Claims (1)
体の接近により人体からの輻射赤外線を検出して
該輻射赤外線の量に応じた検出信号を出力する赤
外線検出部と、前記検出信号を増幅して増幅検出
信号を出力する増幅部と、前記増幅検出信号と基
準信号とを比較し前記増幅検出信号が前記基準信
号より大きいときに検知信号を出力する比較部と
、前記検知信号により駆動信号を出力する駆動部
と、前記駆動信号により自走発振し警報部に発振
信号を出力する発振部とを備えた盗難警報装置。 an infrared detection section that is installed near a device that is a target of theft prevention and that detects infrared rays radiated from a human body when the human body approaches and outputs a detection signal corresponding to the amount of the infrared rays; an amplification section that outputs an amplified detection signal; a comparison section that compares the amplified detection signal with a reference signal and outputs a detection signal when the amplified detection signal is greater than the reference signal; and outputs a drive signal based on the detection signal. and an oscillation section that self-progresses in response to the drive signal and outputs an oscillation signal to an alarm section.
