In this case, even if the configuration of the operation button unit 201 is not provided, when the operator starts to move the X-ray tube 200, it is detected and prepared for automatic alignment, and then the operator first moves the X-ray tube 200 to the patient's vicinity. When the X-ray tube 200 is stopped by releasing the hand after moving it, it is detected and the intraoral sensor of the patient and the X-ray tube 200 are automatically aligned without the need for a second command by the control button unit 201. It is possible to operate in such a way that

Specifically, the X-ray tube 200 may be primarily moved to the vicinity of the X-ray receiver 300 by an external force. At this time, when the X-ray tube 200 is moved by an external force, it is possible to move the X-ray tube 200 more easily by generating a certain amount of torque from a torque motor.

At this time, the first sensor unit 210 can detect a certain amount of torque generated by the torque motor, and when the torque is detected, the alignment confirmation unit 250 is aligned with the X-ray receiver 300 at an optimal alignment position. coordinates can be calculated.

Thereafter, when the movement of the X-ray tube 200 is stopped or torque is not generated by the torque motor, the first sensor unit 210 detects this and based on the alignment position coordinates calculated by the alignment confirmation unit 250 The X-ray tube 200 can be moved automatically.
