## Abstract

A digital X-ray detector is provided, and the digital X-ray detector includes an X-ray detection array configured to detect an X-ray image when a subject is irradiated with X-ray; a support board configured to support a lower part of the X-ray detection array and have a bottom surface thereon a plurality of spaced-apart first joining portions are formed; an external case configured to accommodate the X-ray detection array and the support board and have an inner bottom surface thereon a plurality of second joining portions are formed to correspond to the plurality of first joining portions; and shock absorption members configured to be vertically arranged between the bottom surface of the support board and the inner bottom surface of the external case, each shock absorption member having an upper end to be coupled to the first joining portion and a lower end to be coupled to the second joining portion.

## Claims

### Claim 1

A digital X-ray detector comprising:
an X-ray detection array configured to detect an X-ray image when a subject is irradiated with X-ray;
a support board configured to support a lower part of the X-ray detection array and have a bottom surface thereon a plurality of spaced-apart first joining portions are formed;
an external case configured to accommodate the X-ray detection array and the support board and have an inner bottom surface thereon a plurality of second joining portions are formed to correspond to the plurality of first joining portions; and
shock absorption members configured to be vertically arranged between the bottom surface of the support board and the inner bottom surface of the external case, each shock absorption member having an upper end to be coupled to the first joining portion and a lower end to be coupled to the second joining portion.

### Claim 2 (depends on 1)

The digital X-ray detector of claim 1, wherein each of the first joining portions comprises a first groove which the upper end of the shock absorption member is inserted into, and each of the second joining portions comprises a second groove which the lower end of the shock absorption member is inserted into.

### Claim 3 (depends on 2)

The digital X-ray detector of claim 2, wherein the first grooves are convex with respect to protrusions formed on the bottom surface of the support board, and the second grooves are convex with respect to protrusions formed on the inner bottom surface of the external case.

### Claim 4 (depends on 2)

The digital X-ray detector of claim 2, wherein the first grooves are convex on the bottom surface of the support board, and the second grooves are convex on the inner bottom surface of the external case.

### Claim 5 (depends on 2)

The digital X-ray detector of claim 2, wherein the first grooves and the second grooves have a circular or polygonal cross-section, and the shock absorption members have a same as a cross-section of the first grooves and the second grooves.

### Claim 6 (depends on 1)

The digital X-ray detector of claim 1, wherein the shock absorption members has a ring shape with a hollow which is formed along a vertical direction.

### Claim 7 (depends on 1)

The digital X-ray detector of claim 1, further comprising:
a buffer inserted between a top surface of the X-ray detection array and an inner top surface of the external case.
