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 disposed in periphery of the convex portion above the housing surface and suppresses the pressing force given to the subject by the convex portion.
Claims20
A biological information detection apparatus comprising:
- 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 disposed in periphery of the convex portion above the housing surface and suppresses the pressing force given to the subject by the convex portion,
- wherein, when a value obtained by subtracting the height of the pressing force suppression unit from the height of the convex portion in a direction orthogonal to the housing surface is Δh, Δh>0.
A biological information detection apparatus comprising:
- 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 disposed in periphery of the convex portion on the housing surface and suppresses the pressing force given to the subject by the convex portion,
- wherein 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.
A biological information detection apparatus comprising:
- 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 disposed in periphery of the convex portion above the housing surface and suppresses the pressing force given to the subject by the convex portion,
- wherein, when a latitudinal direction of the pressing force suppression surface is a first direction, a longitudinal direction of the pressing force suppression surface is a second direction, a position away from the position of the convex portion at a first distance in the second direction is a first position, a position away from the position of the convex portion at a second distance longer than the first distance in the second direction is a second position, the height of the pressing force suppression surface in a direction orthogonal to the housing surface at the first position is HS1, and the height of the pressing force suppression surface in the direction orthogonal to the housing surface at the second position is HS2, HS1>HS2.
