## Abstract

An aligning bite of an X-ray device for aligning a subject to an X-ray imaging point and an X-ray device having the same are disclosed. The aligning bite of an X-ray may include a support unit being rotatably connected to a bite stand supporting the aligning bite, and a bite unit being rotatably connected to the support unit, wherein the support unit may include a link frame supporting the bite unit by connecting the bite unit to the bite stand, a first joint rotatably connecting one side of the link frame to the bite stand, a second joint rotatably connecting the bite unit to another side of the link frame, and a third joint being provided between the first joint and the second joint so as to allow the link frame to be folded.

## Claims

### Claim 1

As an aligning bite of an X-ray device for aligning a subject to an X-ray imaging point, the aligning bite of an X-ray device comprising:
a support unit being rotatably connected to a bite stand supporting the aligning bite; and
a bite unit being rotatably connected to the support unit,
wherein the support unit comprises a link frame supporting the bite unit by connecting the bite unit to the bite stand, a first joint rotatably connecting one side of the link frame to the bite stand, a second joint rotatably connecting the bite unit to another side of the link frame, and a third joint being provided between the first joint and the second joint so as to allow the link frame to be folded.

### Claim 2 (depends on 1)

The aligning bite of claim 1, wherein the link frame comprises:
a first link member being connected to the bite stand by the first joint; and
a second link member being connected to the first link member by the third joint.

### Claim 3 (depends on 2)

The aligning bite of claim 2, wherein the second link member is connected to the bite unit by the second joint.

### Claim 4 (depends on 1)

The aligning bite of claim 1, wherein the bite unit comprises:
a bite support stand being rotatably connected to the link frame by the second joint; and
a bite piece being mounted to the bite support stand so as to be bitten between upper teeth and lower teeth of an examinee (or subject of examination).

### Claim 5 (depends on 4)

The aligning bite of claim 4, wherein the bite piece has an arched shape respective to a dental arch form.

### Claim 6 (depends on 4)

The aligning bite of claim 4, wherein the bite piece is mounted to the bite support stand so as to allow a height of the bite piece to be adjusted.

### Claim 7 (depends on 5)

The aligning bite of claim 5, wherein the bite support stand comprises a first bite mounting part and a second bite mounting part each supporting the bite piece at different heights.

### Claim 8 (depends on 4)

The aligning bite of claim 4, wherein a plurality of pass-through holes is formed on the bite piece.

### Claim 9 (depends on 1)

The aligning bite of claim 1, wherein a fastening holder is equipped to the support unit so as to simultaneously lock the first joint, the second joint, and the third joint.

### Claim 10 (depends on 9)

The aligning bite of claim 9, wherein the fastening holder maintains a position of the aligning bite by simultaneously locking movements of the link frame and the bite unit.

### Claim 11

An X-ray device, comprising:
an aligning bite of the X-ray device aligning a subject to an X-ray imaging point;
an X-ray generator emitting X-ray beams toward the subject; and
a detector moving while being in a state of facing into the X-ray generator, and
wherein the aligning bite comprises:
a support unit being rotatably connected to a bite stand supporting the aligning bite; and
a bite unit being rotatably connected to the support unit,
wherein the support unit comprises a link frame supporting the bite unit by connecting the bite unit to the bite stand, a first joint rotatably connecting one side of the link frame to the bite stand, a second joint rotatably connecting the bite unit to another side of the link frame, and a third joint being provided between the first joint and the second joint so as to allow the link frame to be folded.

### Claim 12 (depends on 2)

The aligning bite of claim 2, wherein the bite unit comprises:
a bite support stand being rotatably connected to the link frame by the second joint; and
a bite piece being mounted to the bite support stand so as to be bitten between upper teeth and lower teeth of an examinee (or subject of examination).

### Claim 13 (depends on 3)

The aligning bite of claim 3, wherein the bite unit comprises:
a bite support stand being rotatably connected to the link frame by the second joint; and
a bite piece being mounted to the bite support stand so as to be bitten between upper teeth and lower teeth of an examinee (or subject of examination).
