ABSTRACT:
An X-ray examination apparatus (1), includes a patient table (2) and an X-ray spotfilm device (4) which is reciprocatable in at least two spatial directions relative to the patient table (2), as well as sensors (8a, 8b, 8c, 8d) which are integrated in an operating grip (10) of the X-ray spotfilm device (4) and which serve to activate at least one servomotor (5,7) for the X-ray spotfilm device. In order to make a single operating grip (10) suffice for sliding the X-ray spotfilm device in at least four feasible of movement, the sensors are arranged in such a manner that when the operating grip is exposed to a force in an arbitrary one of the at least four feasible directions of movement, each time a different group (8a, 8b; 8c, 8d; 8a, 8c; 8b, 8d) of sensors (8a, 8b, 8c, 8d) is activated.
