Biological Information Detection Apparatus

Abstract

A biological information detection apparatus includes a detection unit which has a light receiving unit receiving light from a subject, a light transmitting member which is provided on a housing surface side in contact with the subject of the biological information detection apparatus, transmits light from the subject, and has a convex portion in contact with the subject to give a pressing force to the subject when measuring biological information of the subject, and a pressing force suppression unit which is provided so as to surround the convex portion on the housing surface and suppresses the pressing force given to the subject by the convex portion. When a value obtained by subtracting the height HB of the pressing force suppression unit from the height HA of the convex portion in a direction orthogonal to the housing surface is Delta h, Delta h> > 0. The pressing force suppression unit has a pressing force suppression surface which extends in a second direction orthogonal to a first direction as a circumferential direction of a region to be detected of the subject in plan view in a direction orthogonal to the housing surface.

Description

[0001] This application includes the contents of Japanese Patent Application No. 2013-054493 filed on March 18, 2013 and Japanese Patent Application No. 2013-54492 filed on March 18, 2013. technical field [0002] The present invention relates to a living body information detection device and the like. Background technique [0003] Conventionally, there is known a living body information detection device that detects living body information such as pulse waves of humans. JP-A-2011-139725 and JP-A-2009-201919 disclose the prior art of a pulse meter as an example of such a living body information detection device. A pulsometer is attached to, for example, an arm, a wrist, a finger, etc., and detects the pulse based on the heartbeat of a human body, and measures the pulse rate. [0004] The pulsometers disclosed in Japanese Patent Application Laid-Open No. 2011-139725 and Japanese Patent Laid-Open No. 2009-201919 are photoelectric pulsometers. A light emitting unit, and a lig...

Problems solved by technology

[0007] In addition, for example, when the load of the loading mechanism is small, if the convex portion cannot apply sufficient initial pressure to the object to be detected, there is a problem that an appropriate detection signal of biological information cannot be obtained.
