Patent ID: 8073100

Claim:
A panoramic X-ray apparatus, comprising at least a support element, a patient support arranged to be movable in a vertical direction and an imaging station, which panoramic X-ray apparatus has a support structure arranged to support at least the imaging station, and which panoramic X-ray apparatus has an actuator producing a vertical linear motion for moving at least the imaging station to different height positions, characterized in that the panoramic X-ray apparatus comprises a transmission mechanism which affects the velocity/travel distance of the vertical movement of the imaging station and which is connected at least to the actuator and either to the aforesaid support structure or to the aforesaid support element in such manner that the velocity/travel distance of the vertical movement of the imaging station is substantially greater than the velocity/travel distance of the motion imparted by the actuator to the transmission mechanism, the transmission mechanism comprising at least a first diverting pulley and a second diverting pulley, wherein a distance between the first diverting pulley and the second diverting pulley is arranged to be variable by means of the actuator during vertical movement of the imaging station.
