Abstract

An X-ray targeting mechanism or X-ray spot film device including switching means for the organwise-programmed setting of exposure data on a command component. The switching means is constructed of a multi-position or rotary step switch. A plurality of legend-bearing or color-coded viewing frames are associated with the switch, and indicate the particular combinations of exposure data or organs related to each individual switch step position. PAC FIELD OF THE INVENTION The present invention relates to an X-ray targeting mechanism or spot film device including switching means for the organwise-programmed setting of exposure data on a command component. PAC DISCUSSION OF THE PRIOR ART An X-ray targeting mechanism or spot film device of this type has become known through prospectus SR 850 of Hofmann GmbH, Erlangen, West Germany. A command component is provided in this known X-ray targeting mechanism wherein, in addition to keys for effecting the organwise-programmed setting of exposure data, there is also provided a rotary switch for the free or unrestricted setting thereof. An X-ray targeting mechanism or spot film device should be constructed so as to be as compact and space-saving a…
