Abstract

The invention provides a base plate measuring device. Which can rightlt measure enlarged base plate. The metroscope comprise: pedestal (10); objective table (14), which is not stressed by pedestal but is supported by pedestal with its surface inclined a minute angle in relative to vertical direction; guide roller (42) and depressing roll (43), which supports lower part of measured base plate (100); platform (15), which is guided by rail (45) installed on upper and lower of objective table, and moves right and left along objective table surface; camera (18), guided by rail (53) set on platform and move up and down along platform.

Description

technical field [0001] The present invention relates to a substrate measuring device for measuring substrates such as mask substrates used for producing printed circuit boards and glass substrates for liquid crystal display panels. Background technique [0002] As one of such substrate measuring devices, a length measuring instrument for measuring the distance between two points on the substrate surface has been used (see Patent Document 1). Such a length measuring instrument adopts a structure in which an imaging unit movable in the X and Y directions is provided along the surface of the stage on which the substrate is mounted, and the imaging unit is used to image the surface of the substrate. The movement amount of the imaging unit at two points is used to measure the distance between the two points. [0003] However, with the increase in the size of the substrate in recent years, the above-mentioned length measuring instrument has a problem that the substrate placed on ...
