Abstract
Abstract A light distributor for directing the light of the output image of an x-ray image intensifier to a number of different types of cameras in an x-ray diagnostics installation has a housing to which the cameras are attached with their respective beam path axes disposed perpendicularly relative to each other and perpendicularly relative to the axis of the beam path from the x-ray image intensifier. A first mirror deflects the beam from the x-ray image intensifier to one of the cameras, and a second moveable mirror is introducible into the beam path between the first mirror and the first camera to deflect the beam from the x-ray image intensifier onto a second camera.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
188 words
In an x-ray diagnostics installation having an x-ray image intensifier with a beam path for light forming an output image of said x-ray image intensifier, and a plurality of pick-up components for said light, the improvement of a light distributor comprising: a housing into which light comprises said output image of said x-ray image intensifier on said x-ray image intensifier beam path is admitted in an incoming direction; a first mirror disposed in said housing in said x-ray image intensifier beam path which deflects said light in a direction substantially perpendicular to said incoming direction onto a first of said plurality of pick-up components; a second mirror in said housing moveable to a position to deflect light from said beam path of said x-ray image intensifier, after deflection by said first mirror, substantially perpendicularly to said incoming direction and substantially perpendicularly to the deflection of said light by said first mirror onto a second of said plurality of said image pick-up components; and means for laterally moving said second mirror into a beam path between said first mirror and said first of said plurality of said pick-up components.
Claim 2
Dependent Claim
188 words
In an x-ray diagnostics installation having an x-ray image intensifier with a beam path for light forming an output image of said x-ray image intensifier, and a plurality of pick-up components for said light, the improvement of a light distributor comprising: a housing into which light comprises said output image of said x-ray image intensifier on said x-ray image intensifier beam path is admitted in an incoming direction; a first mirror disposed in said housing in said x-ray image intensifier beam path which deflects said light in a direction substantially perpendicular to said incoming direction onto a first of said plurality of pick-up components; a second mirror in said housing moveable to a position to deflect light from said beam path of said x-ray image intensifier, after deflection by said first mirror, substantially perpendicularly to said incoming direction and substantially perpendicularly to the deflection of said light by said first mirror onto a second of said plurality of said image pick-up components; and means for laterally moving said second mirror into a beam path between said first mirror and said first of said plurality of said pick-up components.
Claim 3
Dependent Claim
16 words
A light distributor as claimed in claim 1, wherein said second mirror is a semi-reflecting mirror.
Claim 4
Dependent Claim
79 words
A light distributor as claimed in claim 1, wherein said means for laterally moving said second mirror comprising: two guide rods in said housing disposed on opposite sides of said beam path between said first mirror and said first of said plurality of said pick-up components; a carriage to which said second mirror is attached, said carriage having means engaging each of said first and second guide rods for permitting sliding movement of said carriage along said guide rods.
Claim 5
Dependent Claim
27 words
A light distributor as claimed in claim 3, wherein said means for permitting sliding movement includes at least one spherical liner embracing one of said guide rods.
Claim 6
Dependent Claim
26 words
A light distributor as claimed in claim 3, wherein said means for permitting sliding movement includes at least one roller engaging one of said guide rods.
Claim 7
Dependent Claim
39 words
A light distributor as claimed in claim 3, wherein said means for laterally moving said second mirror further comprises a crank mechanism in said housing including a rotary drive, and means for coupling said crank mechanism to said carriage.
Claim 8
Dependent Claim
80 words
A light distributor as claimed in claim 6, wherein said crank mechanism includes a curved arm attached to said rotary drive, and wherein said means for coupling comprises: a lever having a first end pivotally mounted in said housing and having a second end with an oblong opening therein, a pin attached to said carriage and received in said oblong opening, and means for pivotably connecting said lever to said curved arm between said first end and said opposite end.
