FIXING INSTRUMENT AND METAL MESH DEVICE

摘要

A fixing instrument includes a first frame member (2) and a second frame member (3) that clamp and fix an aperture array structure. At least any of conditions of Expression 1: A1+C>B1 and Expression 2: A2+C>B2 is satisfied where A1 represents a distance between a first reference surface (22a) and a first inner peripheral fitting face (21a), A2 represents a distance between the first reference surface (22a) and a first outer peripheral fitting face (21b), B1 represents a distance between a second reference surface (32a) and a second inner peripheral fitting face (31a), B2 represents a distance between the second reference surface (32a) and a second outer peripheral fitting face (31b), and C represents a thickness of an outer peripheral section (102) of the aperture array structure.

1. A fixing instrument adapted to support an aperture array having a central aperture array section with a plurality of apertures extending through opposite surfaces of the aperture array section, and an outer peripheral section surrounding the aperture array section, the fixing instrument, comprising:
first and second frame members adapted to clamp the outer peripheral section of the aperture array so as to support the aperture array section in a plane; the first frame member having:
a first cavity in which at least a portion of the aperture array section will be located when the outer peripheral section of the aperture array is clamped by the first and second frame members,a frame shaped first fixing part that surrounds at least part of the first cavity; anda first flange part which extends around at least part of the first fixing part; the second frame member having:
a second cavity in which at least a portion of the aperture array section will be located when the outer peripheral section of the aperture array is clamped by the first and second frame members;a frame shaped second fixing part that surrounds at least part of the second cavity; anda second flange part which extends around at least part of the second fixing part; the first flange part of the first frame member and the second flange part of the second frame member having opposed first and second reference surfaces, respectively; the first fixing part having first inner and outer peripheral fitting faces that oppose second inner and outer peripheral fitting faces of the second fixing part, respectively, with respective portions of the outer peripheral section of the aperture array being located between the first and second outer peripheral fitting faces on the one hand the first and second inner peripheral fitting faces on the other; the first inner peripheral fitting face extending a distance A1 from the first reference surface as measured in a direction perpendicular to the plane of the aperture array section, the first outer peripheral fitting face extending a distance A2 from the first reference surface as measured in a direction perpendicular to the plane of the aperture array section, the second inner peripheral fitting face extending a distance B1 from the second reference surface as measured in a direction perpendicular to the plane of the aperture array section, the second outer peripheral fitting face extending a distance B2 from the second reference surface as measured in a direction perpendicular to the plane of the aperture array section, the outer peripheral surface of the aperture array having a thickness C as measured in a direction perpendicular to the plane of the aperture array section; and the dimensions of the first and second frame members satisfying at least one of the following conditions:
