## Abstract

A biometric information acquisition device includes a camera configured to capture an image of a hand of a user inserted into an imaging space, an illumination configured to illuminate inside of the imaging space from above, a housing configured to accommodate the camera and the illumination, and a first opening formed by cutting out a part of the housing and provided in a rectangular shape in a front view to form the imaging space.

## Claims

### Claim 1

A biometric information acquisition device, comprising:
a camera configured to capture an image of a hand of a user inserted into an imaging space;
an illumination configured to illuminate an inside of the imaging space from above;
a housing configured to accommodate the camera and the illumination;
a first opening formed by cutting out a part of the housing and provided in a substantially rectangular shape in a front view to form the imaging space;
a mirror configured to reflect light of the illumination; and
a display configured to prompt a palm of the user to be inserted toward a top surface side of the housing,
wherein the mirror reflects the light of the illumination and illuminates the inside of the imaging space from above.

### Claim 2 (depends on 1)

The biometric information acquisition device according to claim 1, wherein
the housing has a second opening above the imaging space, and
the illumination illuminates the inside of the imaging space from above the second opening.

### Claim 3 (depends on 1)

The biometric information acquisition device according to claim 1, wherein
the housing has the first opening between a top surface of the housing and a bottom surface of the housing.

### Claim 4 (depends on 1)

The biometric information acquisition device according to claim 1, wherein
a height of the imaging space is equal to or less than a total height of a depth of field of the camera and a thickness of a finger of the user.

### Claim 5 (depends on 1)

The biometric information acquisition device according to claim 1, wherein
the first opening is formed on a front surface side of the housing, and
an opening upper end portion of the first opening in the front view is formed to be positioned on the top surface side of the housing from a back surface of the housing to a front surface of the housing.

### Claim 6 (depends on 1)

The biometric information acquisition device according to claim 1, wherein
the first opening is formed on a front surface side of the housing, and
an opening height of the first opening in a side view is formed such that the opening height increases from a back surface of the housing to a front surface of the housing.

### Claim 7 (depends on 2)

The biometric information acquisition device according to claim 2, wherein
the second opening is smaller than an angle of view of the camera.

### Claim 8 (depends on 2)

The biometric information acquisition device according to claim 2, wherein
the second opening is smaller than an illumination range of the illumination.

### Claim 9 (depends on 1)

The biometric information acquisition device according to claim 1,
wherein the mirror is further configured to reflect the hand in the imaging space, and
the camera captures the image of the hand reflected on the mirror.

### Claim 10 (depends on 1)

The biometric information acquisition device according to claim 1, wherein
the housing further includes a gravity center portion on a bottom surface side than the imaging space.
