Section: claims

1. An X-ray reflecting device comprising: a reflecting mirror comprising an elastically deformable material;  a support member; and  a means for applying an external force to an outer periphery or a rear surface of said reflecting mirror; wherein 2. The X-ray reflecting device as defined in claim 1, wherein said reflecting mirror has an aspherical surface. 3. The X-ray reflecting device as defined in claim 1, wherein said reflecting mirror has a second spherical surface, and the centers of said first spherical surface and said second spherical surface are deviated from each other. 4. The X-ray reflecting device as defined in claim 1, wherein the thickness of said reflecting mirror varies in a radial direction of said mirror. 5. The X-ray reflecting device as defined in claim 1, wherein the thickness of said reflecting mirror varies in a circumferential direction of said mirror. 6. The X-ray reflecting device as defined in claim 1, wherein compressed fluid is introduced into said space to apply said external force to said reflecting mirror. 7. The X-ray reflecting device as defined in claim 1, wherein a ring-like piezoelectric element is interposed between said outer periphery of said reflecting mirror and an inner periphery of said support member. 8. The X-ray reflecting device as defined in claim 1, wherein a plurality of piezoelectric elements are distributed in a circumferential direction of said mirror and between said outer periphery of said reflecting mirror and an inner periphery of said support member. 9. The X-ray reflecting device as defined in claim 1, wherein said support member has a pair of members interposing said reflecting mirror therebetween, wherein said paired members are connected to each other by a male screw provided on one member of said paired members and a female screw provided on the other member of said paired members, and wherein said reflecting mirror is deformed by varying a screw-in depth.
