Abstract

A personal identification apparatus includes a finger inlet into which a finger inserted; an interface where the finger is introduced through the finger inlet; a plurality of light sources provided inside the interface to irradiate light to the finger from a plurality of directions; image pick-up units being respectively arranged opposite to the plurality of light sources and respectively capturing an image from light transmitted from the plurality of light sources through the finger; a unit for adjusting when the plurality of light sources transmit light onto the finger; and a unit for extracting blood vessel patterns contained in images captured by the image pick-up units from the light transmitted though the finger and collating each of the extracted blood vessel patterns with a registered blood vessel pattern for personal identification.

Claims

1. A human body imaging device comprising:

a light source that irradiates a light to a finger placed into a case; and

an imaging unit that captures the light that is irradiated from the light source and is passed through the finger,

wherein a part of the case has a shape that protrudes along a side of the finger placed therein, and a space where the finger can move is formed beside the protruded part.

9. The human body imaging device according to claim 1, wherein personal identification is executed by using an image captured by the imaging unit.

10. The human body imaging device according to claim 1, wherein an image captured by the imaging unit is an image which includes at least one of a finger vein and a finger print.

2. A human body imaging device comprising:

a light source that irradiates a light to a finger placed into a case; and

an imaging unit that captures the light that is irradiated from the light source and is passed through the finger,

wherein the case has a protruded part that forms an L-shape.

3. A human body imaging device comprising:

a light source that is installed in a case and which irradiates a light to a finger placed into the case; and

an imaging unit that captures the finger placed to the case,

wherein the light source is located obliquely upward relative to a bottom of the case, and a space, where the finger can move, is formed at the bottom of the case.

8. The human body imaging device according to claim 3,

wherein a direction from a bottom side of the case to a side of the case along the finger placed therein is defined as an upward direction, where the bottom of the case is formed as a center part of the case and is lower than edge parts of the case.

4. A human body imaging device comprising:

a light source that irradiates a light to a finger placed into a case; and

an imaging unit that captures the light that is irradiated from the light source and is passed through the finger,

wherein a part of the case has a shape that protrudes along a side of the finger placed therein, so that an upper side of the finger placed there in faces an open portion of the case.

5. A human body imaging device comprising:

a light source that irradiates a light to a finger placed into a case; and

an imaging unit that captures the light that is irradiated from the light source and is passed through the finger,

wherein a part of the case has a protruding portion from a side of a bottom of the case, and

wherein a space where the finger can move is formed by the protruding portion and the bottom of the case.

6. A human body imaging device comprising:

a light source that irradiates a light to a finger placed into a case; and

an imaging unit that captures the light that is irradiated from the light source and is passed through the finger,

wherein a part of the case has a protruding portion, so that a space is formed beside the protruding portion, whereby the finger can move from one side of the case to another side of the case.

7. A human body imaging device comprising:

a light source that irradiates a light to a finger placed into a case; and

an imaging unit that captures the light that is irradiated from the light source and is passed through the finger,

wherein the case has a concave shape so as to form a groove, whereby the finger placed in the case can move in a longitudinal direction of the groove.
