Abstract: A panoramic X-ray apparatus, comprising at least a support element (2), a patient support (9) arranged to be movable in a vertical direction and an imaging station (4a). The panoramic X-ray apparatus has a support structure (4) arranged to support at least the imaging station (4a), and it has an actuator (15) producing a vertical linear motion for moving at least the imaging station (4a) to different height positions. The panoramic X-ray apparatus comprises a transmission mechanism (28) which affects the velocity/travel distance of the vertical movement of the imaging station (4a) and which is connected at least to the actuator (15) and either to the aforesaid support structure (4) or to the aforesaid support element in such manner that the velocity/ travel distance of the vertical movement of the imaging station (4a) is substantially greater than the velocity/ travel distance of the motion imparted by the actuator (15) to the transmission mechanism (28).
