Patent attributes
An X-ray detecting device comprises a support mechanism for supporting a detector housing pivotably about a horizontal shaft parallel to an X-ray incidence surface, a shaft connected at one end to the detector housing and having an opposite end adapted to perform a rectilinear motion to induce a pivotal motion of the detector housing, a drive mechanism having a drive end connected to the opposite end of the shaft, the drive mechanism inducing the rectilinear motion of the opposite end of the shaft in a mutually connected state of the drive end and the opposite end of the shaft, a switching mechanism for between connection and non-connection of the opposite end of the drive shaft and the drive end, a brake mechanism for inhibiting the pivotal motion of the detector housing, and brake operating means for switching between operation and non-operation of the brake mechanism.
