The storage unit 100 may further include at least one slot 110, 120 through which at least one X-ray detector 30 may be housed.

The sizes of the at least one slot 110, 120 may be different from each other. The size of the at least one slot 110, 120 is determined by the size of at least one x-ray detector 30 housed in at least one slot 110, 120. As an example, the at least one slot 110, 120 may include a first slot 110 in which a relatively small x-ray detector is received and a second slot 120 in which a relatively large x-ray detector is received . However, the sizes of the at least one slot 110 and 120 are not limited to the mutually different sizes, and may be variously modified. As an example, the sizes of at least one slot 110, 120 may be equal to each other. In addition, the number of at least one slot 110, 120 is not limited to two.

The storage unit 100 may further include barrier ribs 130, 131, 132 and 133 for partitioning at least one slot 110 and 120. The plurality of slots 110 and 120 may face each other with the partition 130, 131, 132, and 133 interposed therebetween. For example, the first slot 110 and the second slot 120 may face each other with the partition 130, 131 interposed therebetween. The partition walls 130 and 131 may extend from the side wall of the body 101 to the inside of the housing unit 100.

The receiving unit 100 may further include a bottom plate 140 defining at least one slot 110, 120 together with the partitions 130, 131, 132, 133. Specifically, at least one of the slots 110 and 120 may be defined by the side wall of the body 101, the partitions 130, 131, 132, and 133, and the bottom plate 140.

Meanwhile, the slot 120 can accommodate the X-ray detector 400 or the X-ray detector 410 having different sizes.

The X-ray detector 400 may include a battery 403 therein. According to the embodiment, the X-ray detector 400 may further include a wireless power receiving unit in a region where the battery 403 is disposed.

The X-ray detector 410 may include a battery 413 therein. According to the embodiment, the X-ray detector 410 may further include a wireless power receiving unit in a region where the battery 413 is disposed.

As shown in Fig. 4, the receiving unit 100 may further include at least one damping unit (150, 155). At least one damping unit 150 or 155 serves to mitigate an impact on the X-ray detector 30 in the process of housing the X-ray detector 30 in the housing unit 100. At least one damping unit 150 may be installed in the bottom plate 140. When the X-ray detector 30 is inserted into at least one of the slots 110 and 120, gravity acts on the X-ray detector 30. By the action of gravity, the insertion speed of the X-ray detector 30 with respect to at least one of the slots 110 and 120 is accelerated in the insertion direction I of the X-ray detector 30 (see FIG. 7B). Accordingly, the X-ray detector 30 may collide with the inner wall of at least one of the slots 110 and 120, particularly, the bottom plate 140 of at least one of the slots 110 and 120 in the process of being accommodated in at least one of the slots 110 and 120 . Collision with the X-ray detector 30 and the bottom plate 140 of at least one of the slots 110 and 120 may cause breakage or damage of the X-ray detector 30. In particular, breakage or damage to the terminal portion 31 formed on one side of the X-ray detector 30 and a connector 160 to be described later may be significant. In order to mitigate the shock applied to the X-ray detector 30 in the process of housing the X-ray detector 30 in at least one of the slots 110 and 120, the bottom plate 140 of at least one slot 110, , Urethane, silicone, or the like can be disposed. However, the cushioning member alone can not sufficiently mitigate the shock applied to the X-ray detector 30. Since the insertion speed of the X-ray detector 30 is not accelerated by the insertion direction I of the X-ray detector 30 (see FIG. 7B) only by the arrangement of the cushioning member, It is difficult to expect accurate docking of the connector 160 of FIG. That is, the X-ray detector 30 and the connector 160 are docked by the magnetic force. When the insertion speed of the X-ray detector 30 to at least one of the slots 110 and 120 is excessively fast, It is difficult to expect accurate coupling between the terminal portion 31 of the X-ray detector 30 and the connector 160 because the gravity acts more strongly between the connectors 160 than the magnetic force.

In order to solve such a problem, at least one damping unit 150, 155 may be provided in the receiving unit 100. [ The at least one damping unit 150 and 155 may mitigate the impact that may be applied to the X-ray detector 30 in the process of housing the X-ray detector 30, The acceleration of the X-ray detector 30 with respect to the connector 160 can be prevented by preventing the acceleration in the direction I (see FIG. 7B).

The at least one damping unit 150, 155 may include an air damper, a hydraulic damper, a gas damper, or the like.

A detailed description of the structure of the at least one damping unit 150, 155 will be described later.

As shown in Fig. 4, the housing unit 100 may further include a connector 160. Fig. The connector 160 may be disposed in the receiving unit 100 so as to be coupled to the terminal portion 31 formed on one side of the X-ray detector 30. In other words, the connector 160 can be disposed in the bottom plate 140 of at least one slot 110, 120 so that it can be docked with terminal portions formed on one side of the x-ray detector.

The X-ray detector 30 can be charged in a state in which the terminal portion 31 of the X-ray detector 30 is housed in at least one of the slots 110 and 120 by being docked to the connector 160. The X-ray detector 30 can transmit and receive an electrical signal to / from a control unit (not shown) by docking the terminal unit 31 of the X-ray detector 30 with the connector 160.

The connector 160 may include a connector terminal portion 161 that engages with the terminal portion 31 of the X-ray detector 30. The connector 160 may further include a connector magnetic body 162 that interacts with the detector magnetic body 32 provided in the x-ray detector 30. [ The connector magnetic body 162 may be provided adjacent to the connector terminal portion 161. Specifically, the connector magnetic body 162 may be provided on both sides of the connector terminal portion 161. [

The connector 160 may be disposed in the bottom plate 140 of the at least one slot 110,120 such that the connector terminal portion 161 and the connector magnetic body 162 are exposed toward the interior of the at least one slot 110,120.

10 is a side sectional view of a receiving unit of a mobile X-ray imaging apparatus according to an embodiment of the present invention. 10 is a side sectional view of the housing unit 100 when the X-ray detector 410 is housed in the second slot 120. FIG.

As shown in FIG. 10, at least one slot 110, 120 of the storage unit 100 may be formed at an angle so as to have a certain angle. In other words, at least one of the slots 110 and 120 of the receiving unit 100 may be formed to be inclined so as to have an angle with respect to the imaginary line G extending along the gravity direction. Preferably, at least one of the slots 110, 120 of the containment unit 100 is formed to be inclined such that it is greater than 0 degrees and less than 90 degrees or less than 90 degrees with respect to the imaginary line G extending along the direction of gravity . More preferably, at least one of the slots 110 and 120 of the receiving unit 100 is formed to be inclined such that it is greater than 0 degrees and less than 45 degrees or less than 45 degrees with respect to the imaginary line G extending along the direction of gravity . As an example, FIG. 10 shows a second slot 120 of the receiving unit 100 formed to be inclined so as to have an angle of about 26 degrees with respect to an imaginary line G extending along the direction of gravity. When the at least one slot 110,120 of the housing unit 100 is formed to be parallel to the imaginary line G extending along the direction of gravity, the magnitude of the gravity acting on the x-ray detectors 400 and 410 is relatively large, A relatively large impact may be applied to the X-ray detectors 400 and 410 when the detectors 400 and 410 are accommodated in at least one slot 110 and 120 of the housing unit 100.

However, when at least one of the slots 110 and 120 of the receiving unit 100 is formed to be inclined at an angle of 90 degrees with respect to the imaginary line G extending along the direction of gravity, It is necessary to inconvenience such as bending the waist in order to accommodate it in at least one slot 110, 120 of the portable terminal 100. Therefore, it is preferable that at least one slot 110, 120 of the receiving unit 100 is formed to be inclined so as to have an angle larger than 0 degrees and smaller than 90 degrees with respect to the imaginary line G extending along the gravity direction. Since the amount of the shock applied to the X-ray detectors 400 and 410 can be defined by various variables such as the weight of the X-ray detectors 400 and 410 and the friction coefficient of the X-ray detectors 400 and 410, 110 and 120 is not limited to the above example. The angles of the at least one slots 110 and 120 of the receiving unit 100 are measured with respect to one surface of the x-ray detectors 400 and 410 housed in at least one slot 110 and 120 of the receiving unit 100. 10, the angle of the second slot 120 is measured about one side of the x-ray detector 410 received in the second slot 120, adjacent to the body 10 (see Fig. 1B) do. The angles of the at least one slot 110, 120 may be equal to each other. That is, the angles of the first slot 110 and the second slot 120 may be equal to each other. However, it is also possible to design the angles of at least one of the slots 110 and 120 to be different from each other.
