Abstract
Abstract A device for translating a slide comprises a frame (15), first and second parallel guide rods (17A and 17B) and first and second bearing means which cooperate with the guide rods. The slide (13) is rectilinearly movable along an X-axis of an orthogonal triaxial system comprising said X-axis, an Y-axis and a Z-axis. The first bearing means comprises a first bearing sleeve (19A1) and a second bearing sleeve (19A2), the slide being supported in the directions of the Y-axis and Z-axis by the first bearing sleeve (19A1) and the first guide rod (17A) and in the direction of the Z-axis by the second bearing sleeve (19A2) and the first guide rod (17A). The second bearing means comprises a bearing sleeve or sleeves 19B or 119B1 and B2) which in cooperation with the second guide rod (17B) supports the slide in the direction of the Y-axis and the Z-axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
215 words
A device for translating a slide, which device comprises a frame and a rectilinear guide means for the slide, the rectilinear guide means comprising parallel first and second guide rods and first bearing means and second bearing means which cooperate with the guide rods to guide the slide relative to the frame in a rectilinear path along an axis of an orthogonal triaxial system comprising said axis and two further axes perpendicular thereto and to one another, characterized in that the first bearing means comprises a first bearing sleeve and a second bearing sleeve through which the first guide rod extends and which cooperate with the rod in such a way that the first guide rod and the first bearing sleeve together support the slide in the directions of said two further axes and the first guide rod and the second bearing sleeve together support said slide only in the direction of one of said two further axes of the orthogonal triaxial system, and the second bearing means comprises a bearing sleeve or sleeves through which the second guide rod extends and which cooperates or cooperate with this rod in such a way that the second guide rod and the second bearing means together support the slide in the directions of said two further axes.
Claim 2
Independent Claim
215 words
A device for translating a slide, which device comprises a frame and a rectilinear guide means for the slide, the rectilinear guide means comprising parallel first and second guide rods and first bearing means and second bearing means which cooperate with the guide rods to guide the slide relative to the frame in a rectilinear path along an axis of an orthogonal triaxial system comprising said axis and two further axes perpendicular thereto and to one another, characterized in that the first bearing means comprises a first bearing sleeve and a second bearing sleeve through which the first guide rod extends and which cooperate with the rod in such a way that the first guide rod and the first bearing sleeve together support the slide in the directions of said two further axes and the first guide rod and the second bearing sleeve together support said slide only in the direction of one of said two further axes of the orthogonal triaxial system, and the second bearing means comprises a bearing sleeve or sleeves through which the second guide rod extends and which cooperates or cooperate with this rod in such a way that the second guide rod and the second bearing means together support the slide in the directions of said two further axes.
Claim 3
Dependent Claim
53 words
A device as claimed in Claim 1, characterized in that the second bearing means comprises only one bearing sleeve, which sleeve, viewed along the rectilinear path of the slide is spaced from the first bearing sleeve of the first bearing means, and in that these two bearing sleeves are identical to each other.
Claim 4
Dependent Claim
143 words
A device as claimed in Claim 1, characterized in that the second bearing means comprise first and second bearing sleeves through which the second guide rod extends and which cooperate with this rod in such a way that the second guide rod and one of the bearing sleeves of the second bearing means together support the slide in the direction of one of the said two further axes and the second guide rod and the other bearing sleeve of the second bearing means together support the slide in the direction of the other of said two further axes, and in that viewed in the direction of the rectilinear path of the slide the second bearing sleeve of the second bearing means is spaced from the second bearing sleeve of the first bearing means, the two second bearing sleeves being identical to each other.
Claim 5
Dependent Claim
24 words
A device as claimed in Claim 1, characterized in that the bearing sleeves are formed integrally with the slide as a single injection-moulded product.
Claim 6
Dependent Claim
99 words
An electrodynamic apparatus for translating an objective having an optical axis along a radial path relaltive to a disc which rotates about an axis of rotation, which apparatus comprises a stationary first magnetic means and a translatable second magnetic means which cooperates magnetically with the first magnetic means, characterized in that the apparatus comprises a device as claimed in Claim 1 for translating a slide on which the objective is arranged in such a manner that one of said two further axes of the orthogonal triaxial system of the device extends parallel to the optical axis of the objective.
