摘要： A comparator (11) outputs, out of an electrical signal input from a trans impedance amplifier (TIA) via a coupling capacitor, pulses having amplitudes equal to or larger than a reference value as a comparison output signal (Cout). An analog holding circuit (12) charges a holding capacitor with each pulse contained in the comparison output signal (Cout) and also removes a DC voltage obtained by the charging via a discharging resistor, thereby generating a holding output signal (Hout) that changes in accordance with the presence/absence of input of an optical signal. This allows to perform an autonomous operation without any necessity of an external control signal and properly detect the presence/absence of input of an optical signal.

摘要： In measurement requiring application of pressure to a tissue of a living body such as blood pressure measurement, noise due to vibration tends to occur. It is difficult to accurately measure a pulse wave and a blood pressure value. It is also difficult to measure blood pressure in life activities or to measure blood pressure at intervals or continuously where a tonometer is always attached. There is consequently a problem of holding a biologic information detecting apparatus. The present invention solves the problems by providing an easy-to-wear biologic information detecting apparatus for stably detecting biologic information. The biologic information detecting apparatus includes a sensor for detecting biologic information in a pair of arms connected via a spindle, and the sensor is tightly attached to a projecting part in a living body, particularly, a tragus of an auricle.
