Patent ID: 7736054

Claim:
An X-ray detecting device comprising: a detector housing comprising an X-ray incidence surface arranged in a changeable direction; a support mechanism configured to support the detector housing pivotably about a horizontal shaft parallel to the X-ray incidence surface; a shaft comprising a first end and an opposite second end, the first end coupled to the detector housing and second end adapted to perform a rectilinear motion to induce a pivotal motion of the detector housing; a drive mechanism comprising a drive end connected one of directly and indirectly to the second end of the shaft, the drive mechanism configured to induce the rectilinear motion of the second end of the shaft in a mutually connected state of the drive end and the second end of the shaft; a switching mechanism configured to switch between a state of connection and a state of non-connection of the second end of the shaft and the drive end; a brake mechanism configured to inhibit the pivotal motion of the detector housing; and a brake operating means configured to switch between a state of operation and a state of non-operation of the brake mechanism.
