An X-ray apparatus is a device that obtains an image of a patient's object (for example, inside the mouth) by using X-rays. The X-ray apparatus radiates an X-ray into the patient's oral cavity, detects an X-ray that has passed through the patient's oral cavity, and images the patient's oral cavity. Therefore, the medical X-ray apparatus can be used for diagnosis of injuries or diseases inside the oral cavity of a patient that cannot be confirmed by appearance. Such an X-ray apparatus includes an X-ray generator that generates X-rays and radiates it to an object, and a detector that detects X-rays transmitted through the object.

In the conventional X-ray apparatus, as shown in FIG. 1, a circuit provided in the X-ray apparatus and a detector are connected by wire.

This structure has a problem in that the distance between the circuit provided in the X-ray apparatus and the detector is long, so that a signal is converted into a long-distance interface standard when transmitting and receiving a signal, or a chipset of the USB standard has to be applied to the detector.

In addition, the conventional detector selects a structure in which the detector is supported with the help of an assistant (for example, a nurse, etc.) or a user's finger, and there is a risk of indirect exposure to the assistant or the user.

Therefore, there is no need to convert to a long-distance interface standard when transmitting and receiving an image signal, and research on a detector that is easy to charge, carry and operate while minimizing the amount of indirect exposure is required.

Referring first to FIGS. 2 to 6, the portable wireless X-ray detector 200 capable of wireless charging according to an embodiment of the present invention includes a sensor unit 210 receiving X-rays radiated from the X-ray radiating apparatus 100, and wireless charging. It can be driven through power supply through the sensor unit 210 and is composed of a circuit unit 220 and an elastic body that receives the image signal acquired from the sensor unit 210 and wirelessly transmits it to the external device 400, and is composed of one surface of the sensor unit 210 and the circuit unit ( It includes a bending unit 230 connecting one side of the 220) and a wireless charging tech 250 for supplying driving power to the circuit unit 220 through wireless charging.

The sensor unit 210 is not limited thereto, but may be formed in a flat plate shape having a rounded corner, and a module 211 for sensing an X-ray signal may be provided on one surface. In addition, since the sensor unit 210 needs to be in close contact with the photographing part in order to accurately photograph the user's X-ray photographing part (eg, the inside of the oral cavity), it is preferable to be formed of an elastic material.

The module 211 receives X-rays generated by the X-ray radiating apparatus, converts the received X-rays into image signals, and transmits them to the circuit unit 220.

The circuit unit 220 may include an outer case 221, a signal receiving unit 222, a wireless communication unit 223, and a wireless charging unit 224.

The outer case 221 is provided in an oval shape, is held by the user's hand, and must be able to withstand the user's grip force, and thus may be made of a material having durability greater than the user's grip force.
