In addition, the X-ray radiator 210 may be connected to the X-ray radiator 210 through the X-ray radiator to activate and deactivate the X-ray radiator 210 that receives power from the power source 230.

According to an exemplary embodiment, the switching unit 320 may have a transition process between the inputs other than a state in which a user input regarding the start of photographing the camera 220 and a user input regarding the end of the photographing are received. That is, in the transition process in which another user input is received while the user input related to one of the start of shooting and the end of shooting is received by the switching unit 320, the switching unit 320 supplies power to the camera controller 340. You can block. As will be described in more detail below, the operation of the camera controller 340 may be reset through such a power cut.

The camera controller 340 may control photographing start and photographing end of the camera 220 according to a user input received by the switching unit 320. That is, the camera controller 340 receives power provided through the switching unit 320 according to a user input, and performs a predetermined operation on the camera 220 through this, so that the camera 220 starts capturing an image. And end. In particular, the camera 220 used in the present invention may be an independently implemented camera equipped with a CMOS image sensor, such as a DSLR camera or a mirrorless camera, and thus the camera controller 340 may be an improvement of the camera 220. Without performing the modification, the camera 220 may be implemented to perform video recording.

Although not shown in FIG. 2, the X-ray imaging apparatus may include a computing device, according to an exemplary embodiment.

The X-ray irradiation control unit 360 is positioned between the switching unit 320 and the X-ray irradiation unit 210 (particularly, the control unit 218 of the X-ray irradiation unit 210), so that the switching unit 320 receives a user input regarding the start of photographing. When receiving, the X-ray radiator 210 may be activated, and when the switching unit 320 receives a user input regarding the end of photographing, the X-ray radiator 210 may be deactivated. That is, the operation of the camera 220 and the operation of the X-ray radiator 210 may be interlocked through the X-ray irradiation controller 360 so that the camera 220 may capture a moving object.

In detail, the X-ray irradiation control unit 360 may be directly or indirectly connected to the control unit of the X-ray irradiation unit 210 to operate and deactivate the X-ray irradiation unit 210 by manipulating the control unit 218.

However, the configuration of the button operation unit 342 is an example, various configurations may be applied according to the embodiment to which the present invention is applied.

The timing relay unit 344 may electrically connect the power supply unit 230, the switching unit 320, and the button operation unit 342 for a predetermined time. That is, the timing relay unit 344 transfers the power provided from the power supply unit 230 to the button operation unit 342 through the switching unit 320, and a predetermined time (for example, 0.1 second to 0.2 second) is performed. When elapsed, it may operate to cut off the power supply.

More specifically, referring to the operation of the X-ray imaging control apparatus 300, first, when the switching unit 320 receives a user input regarding the start of photographing, the power of the power supply unit 230 is switched to the switching unit 320 and the timing relay unit ( It may be delivered to the button operation unit 342 via 344. When a magnetic field is generated in the coil of the button manipulation unit 342 by the power source, the magnetic switch may be moved to press the photographing button of the camera 220. In addition, when a predetermined time elapses in this state, the timing relay unit 344 may cut off the power applied to the button operation unit 342. Therefore, the magnetic field disappears from the coil of the button operation unit 342, and thus the force for moving the magnetic switch disappears, so that the photographing button of the camera 220 is released. As described above, the photographing buttons of the camera 220 are sequentially pressed and released, so that the camera 220 may start photographing.

Similarly, when the switching unit 320 receives a user input regarding the end of photographing, the power of the power supply unit 230 may be transmitted to the button operation unit 342 via the switching unit 320 and the timing relay unit 344. When a magnetic field is generated in the coil of the button manipulation unit 342 by the power source, the magnetic switch may be moved to press the photographing button of the camera 220. In addition, when a predetermined time elapses in this state, the timing relay unit 344 may cut off the power applied to the button operation unit 342. Therefore, the magnetic field disappears from the coil of the button operation unit 342, and thus the force for moving the magnetic switch disappears, so that the photographing button of the camera 220 is released. As described above, while the camera 220 continues to photograph, the photographing buttons of the camera 220 are sequentially pressed and released, thereby allowing the camera 220 to finish photographing.

Referring to FIG. 5, the camera controller 340 ′ may be implemented as a relay 340 ′ connected to the switching unit 320 and the driving circuit of the camera 220.

In detail, when the switching unit 320 receives a user input regarding the start of photographing the camera 220, the power of the power supply unit 230 is provided to the camera controller 340 ′ via the switching unit 320, and the power is applied. The received camera controller 340 ′ may electrically connect the driving circuit (that is, form a closed loop of the driving circuit) to allow the camera 220 to start photographing. Similarly, when the switching unit 320 receives a user input for terminating the shooting of the camera 220, the power of the power supply unit 230 is provided to the camera controller 340 ′ via the switching unit 320, and the camera controller 340. ') May electrically connect the driving circuit to cause the camera 220 to finish photographing.

That is, unlike the camera controller 340 of FIG. 4 directly controlling the photographing button of the camera 220 to control the camera 220, the camera controller 340 ′ of FIG. 5 is a driving circuit in the camera 220.
