PHOTOELECTRIC PULSE WAVE MEASURING INSTRUMENT

摘要

PROBLEM TO BE SOLVED: To accurately measure a wave form of a pulse wave when a photoelectric sensor is attached to a photoelectric sensor holder.SOLUTION: A photoelectric sensor holder 15 includes a sensor installation part 60 to which a photoelectric sensor having a light receiving surface is detachably attached, a pressing unit 30 for pressing the sensor installation part 60, and a pedestal having a seat plate 24 for supporting the pressing unit 30. The sensor installation part 60 can be equipped with the photoelectric sensor so that its light receiving surface is directed to a measurement direction 74. The pressing unit 30 presses the sensor installation part 60 against the same direction as the measurement direction 74. A main plane 18 of the seat plate 24 is parallel with a plane orthogonal to the pressing direction of the pressing unit 30.SELECTED DRAWING: Figure 2
