BIOLOGICAL INFORMATION MEASURING PANEL

摘要

PROBLEM TO BE SOLVED: To provide a biological information measuring panel capable of preventing breakage of a sensor for outputting a signal to be used for measuring biological information of a subject even if great downward loads are applied to a pressure receiving plate disposed on the lower side of the subject.

SOLUTION: The panel 1A includes the pressure receiving plate 2 and a base plate 3. The pressure receiving plate 2 is supported in a state separate from the base plate 3. A cantilevered flat spring 4 which can be elastically bent/deformed downward is formed at the center of the base plate 3 by providing a groove hole 5 penetrating in the direction of thickness of the base plate 2 in such a way as to enclose the periphery of the flat spring 4 except for a fixed end 4a side of the flat spring 4. A presser member 9 for bending/deforming the flat spring 4 by pressing the flat spring 4 downward with the downward vibration of the pressure receiving plate 2 is disposed between the pressure receiving plate 2 and the flat spring 4. Variation of the amount of bending deformation of the flat spring 4 is detected by a detection sensor 10. An output signal from the detection sensor 10 is used for measuring the biological information of the subject.
