Target device for an X-ray examination installation

A target device for an X-ray examination installation comprising:

• a cassette carriage;
• means for moving said cassette carriage relative to an X-radiation cone from a right ready position through at least one exposure position to a left loading position and back for left and right side loading of an X-ray film cassette therein;
• two opposed clamping jaws disposed parallel to one another carried on said cassette carriage, said clamping jaws being two-dimensionally displaceable relative to one another for adjustment in a common plane for receiving and retaining said X-ray film cassette therebetween;
• at least one detent carried on said cassette carriage for fixing the position of said X-ray film cassette in the longitudinal direction of said clamping jaws;
• a clamping slide carried on said cassette carriage and having a projection extending into said common plane of said clamping jaws, and means for moving said clamping slide relative to said carriage in said longitudinal direction of said clamping jaws;
• a pair of tension members respectively interconnected between said clamping slide and said clamping jaws, said tension members being respectively conducted over deflection rollers, said deflection rollers being respectively urged by bias springs in a direction opposing movement of said clamping slide toward the right of said carriage;
• a motor drivingly connected to said clamping slide for transporting said clamping slide from an extreme left position to an extreme right position relative to said cassette carriage, said clamping slide being transported by said motor against the force of said bias springs normally biasing said clamping slide towards said extreme left position;
• and
• at least one spring interconnected between said clamping jaws for biasing said clamping jaws toward each other at said right loading position and for spreading said clamping jaws apart in said left loading position, said clamping slide disposed relative to said clamping jaws for forcing said clamping jaws toward one another against the force of said spring which normally spreads said clamping jaws apart at said left loading position, as said clamping slide is moved from said extreme left position relative to said cassette carriage.
