Abstract

A holder configured to allow light transmission probes for emitting light and light reception probes for receiving light to be arranged alternately and be spaced apart from each other by a second set distance r₂. The holder has a plurality of first through holes each provided at a position spaced apart by a first set distance r₁ shorter than the second set distance r₂ from a position of the retained light transmission probe or a position of the retained light reception probe. Each of the through holes of the plurality of first through holes allow reference probes for emitting or receiving light to be inserted thereto. One of the first through holes provided therein with none of the reference probes has a non-light transmissive attachment member in a detachable manner.

Claims

1. A holder configured to allow light transmission probes for emitting light and light reception probes for receiving light to be arranged alternately and be spaced apart from each other by a second set distance r₂, wherein

the holder has a plurality of first through holes each provided at a position spaced apart by a first set distance r₁ shorter than the second set distance r₂ from a position of a retained light transmission probe or a position of a retained light reception probe,

each of the through holes of the plurality of first through holes allow reference probes for emitting or receiving light to be inserted thereto,

one of the first through holes provided with none of the reference probes allows a non-light transmissive attachment member to be detachable therefrom, and

the holder includes the attachment member.

2. The holder according to claim 1, wherein the first through holes are each formed at a median of a line connecting a position of the retained light transmission probe and a position of the retained light reception probe.

3. The holder according to claim 1, wherein the second set distance r₂ is 30 mm.

4. An optical biometric apparatus comprising:

the holder according to claim 1;

a light transmission probe for emitting light;

a light reception probe for receiving light;

a reference probe for emitting or receiving light; and

a controller for controlling light transmission or light reception of the light transmission probe, the light reception probe, or the reference probe.

5. The holder according to claim 1, wherein

the holder has a plurality of second through holes allowing the light transmission probes or the light reception probes to be inserted thereto, and

one of the second through holes provided with neither the light transmission probe nor the light reception probe allows the attachment member to be detachable therefrom.

6. The holder according to claim 5, wherein the first through holes are each formed at a median of a line connecting a position of the retained light transmission probe and a position of the retained light reception probe.

7. The holder according claim 5, wherein the second set distance r₂ is 30 mm.

8. An optical biometric apparatus comprising:

the holder according to claim 5;

a light transmission probe for emitting light;

a light reception probe for receiving light;

a reference probe for emitting or receiving light; and

a controller for controlling light transmission or light reception of the light transmission probe, the light reception probe, or the reference probe.

9. The holder according to claim 1, wherein the first through holes are each formed at a median of a line connecting a position of the retained light transmission probe and a position of the retained light reception probe, wherein the second set distance r₂ is 30 mm.

11. An optical biometric apparatus comprising:

the holder according to claim 1, wherein the first through holes are each formed at a median of a line connecting a position of the retained light transmission probe and a position of the retained light reception probe;

a light transmission probe for emitting light;

a light reception probe for receiving light;

a reference probe for emitting or receiving light; and

a controller for controlling light transmission or light reception of the light transmission probe, the light reception probe, or the reference probe.

12. An optical biometric apparatus comprising:

the holder according to claim 1, wherein the second set distance r₂ is 30 mm;

a light transmission probe for emitting light;

a light reception probe for receiving light;

a reference probe for emitting or receiving light; and

a controller for controlling light transmission or light reception of the light transmission probe, the light reception probe, or the reference probe.
