Biological information measurement device capable of accurately conducting measurement, that can safely be used
First Claim
1. A biological information measurement device provided with a light emission portion for emitting light to an inserted fingertip and a light reception portion for receiving transmitted light, comprising:
- a first holding portion;
a second holding portion forming a fingertip insertion recess together with said first holding portion, wherein a fingertip is to be inserted into the recess, the second holding portion is opposed to the first holding portion with said fingertip insertion recess lying therebetween, and the second holding portion being capable of relative displacement with respect to the first holding portion in a direction of opening and closing of a fingertip insertion port of said fingertip insertion recess; and
a restriction member for restricting relative displacement of said first and second holding portions to avoid any exposed gap between the first holding portion and the second holding portion, except for the fingertip insertion port of said fingertip insertion recess, forming around the fingertip insertion port of said fingertip insertion recess when said fingertip insertion portion is opened.

Abstract
A biological information measurement device is constituted of an upper cover and a lower cover and a main body portion. Then, the upper cover and the lower cover are assembled such that they partially overlap with each other. A fingertip insertion portion is formed of a holding member, on which a substrate and a line of the main body portion are placed. By covering the whole main body by assembling the upper cover and the lower cover, the substrate and the line of the main body portion arranged on a side surface of the main body in the inside cannot externally be seen.

5. A biological information measurement device provided with a light emission portion for emitting light to an inserted fingertip and a light reception portion for receiving transmitted light, comprising:
-
a first holding portion; a second holding portion forming with said first holding portion a fingertip insertion recess to receive a fingertip, the second holding portion is opposed to the first holding portion with the fingertip recess lying therebetween, and the second holding portion capable of relative displacement with respect to the first holding portion in a direction of opening and closing of a fingertip insertion port to said fingertip insertion recess; wherein each of said first and second holding portions has side portions arranged on respective sides of said fingertip insertion recess, and the side portions of said first holding portion overlap with the side portions of said second holding portion where said fingertip insertion portion is closed, and a restriction member for restricting relative displacement of said first and second holding portions at a position where no gap except for the fingertip insertion port of said fingertip insertion portion is formed around the fingertip insertion port of said fingertip insertion portion when said fingertip insertion portion is opened, and said restriction member restricts relative displacement of said first and second holding portions at a position such that the side portions of said first holding portion and the side portions of said second holding portion overlap with each other while said fingertip insertion recess is opened, wherein a projection is provided in one of the side portions of said first and second holding portions, and a recess is slidably engaged with said projection is provided in the other thereof.

6. A biological information measurement device provided with a light emission portion for emitting light to an inserted fingertip and a light reception portion for receiving transmitted light, comprising:
-
a first holding portion; and a second holding portion forming a fingertip insertion recess together with said first holding portion, wherein a fingertip is to be inserted, provided opposed to the first holding portion with the fingertip disposed in said fingertip insertion recess lying therebetween, and capable of relative displacement with respect to the first holding portion in a direction of opening and closing of a fingertip insertion port of said fingertip insertion recess, and a tip end portion of said first holding portion partially overlapping with a tip end portion of said second holding portion when said fingertip insertion portion recess is closed. - View Dependent Claims (7, 8, 9, 10)

11. A biological information measurement device for measuring biological information while a finger is inserted, comprising:
-
a measurement unit provided with a first member and a second member, said first and second members configured to be relatively displaced to form a finger port and form a holding mechanism for a finger between said first member and said second member, and an electronic component for measuring biological information at a part of the finger held by said holding mechanism; and the first member and the second member structured such that light sensing surface of said measurement unit is entirely and continuously enclosed within said first member and said second member except for the finger port.

12. A biological information measurement device provided with a light emission portion for emitting light to an inserted fingertip and a light reception portion for receiving transmitted light, comprising:
-
a first holding member; a second holding member forming a fingertip insertion recess together with said first holding member, in which said recess a fingertip is to be inserted, provided opposed to the first holding member with the fingertip disposed in said fingertip insertion portion lying therebetween, and capable of relative displacement with respect to the first holding member in a direction of opening and closing of a fingertip insertion port of said fingertip insertion recess, an electronic component implementing said light emission portion being provided in at least one of said first and second holding members, an electronic component implementing said light reception portion being provided in at least one of said first and second holding members; and first and second housings provided to cover said first and second holding members, respectively, on which said electronic component is placed, and said first and second housings being arranged to continuously and at least partially overlap with each other wherein the overlap blocks ambient light from entering the light reception portion.

13. A biological information measurement device comprising:
-
a first holding member including a light emitter mounted in a first finger holding surface; a second holding member including a light receiver provided with a second finger holding surface, wherein the light receiver is oriented to receive light from the light emitter, wherein the second holding member is coupled to the first holding member and is configured to be displaced relative to the first holding member; a fingertip receiving recess formed between the first finger holding member of the first holding member and the second finger holding surface of the second holding member, wherein the relative displacement between the first and second holding member expands and contracts a fingertip inlet port to the fingertip receiving recess; side walls on at least one of said first and second holding portions, wherein the side walls are on opposite sides of and continuously span the fingertip receiving recess during the relative displacement between the first and second holding members, and a restriction member which restricts the relative displacement of said first and second holding portions and the restriction member includes a projection in one of the first or second holding portions which slidably engages a slot in the other of the second or first holding portions.
