Embodiment Construction

[0026] Embodiments of the present invention will be described below based on examples. FIG. 1 is a perspective view showing an embodiment of a two-dimensional coordinate measuring apparatus of the present invention, figure 2 It is a sectional view of line A-A in Fig. 1, image 3 It is the B-B line sectional view of Fig. 1, Figure 4 It is a perspective view of a photomask (スクリ-ソ version), and Fig. 5 is a cross-sectional view of the measuring head.

[0027] In these figures, a two-dimensional coordinate measuring instrument 10 is provided with a measuring instrument body 12 formed in an approximately box shape, and the structure of the two-dimensional coordinate measuring instrument 10 includes a base 14 and a pedestal 16 (26 )Wait. The base 14 is configured using a plurality of frames, and its periphery is covered with a decorative board 15 . The bottom of the base 14 is fixed with a plurality of horizontal adjusting screws 18 for adjusting the inclination between the base...

Abstract

The invention measures the dimension of a measured object on each of a plurality of objects to be measured having different specifications. When a medium-sized screening print 28a is measured, the medium-sized screening print 28a is arranged on a measuring table 24 in an upper part of the measuring apparatus body 12, a Y-axis movable carriage 46 is moved along a Y-axis flame 26, a head 48 is moved along the Y-axis movable carriage 46, and the pattern on the medium-sized screening print 28a is imaged by one of camera units 56, 58, and 60. When a large screening print 28b is measured, the large screening print 28b is arranged on a frame 38 and a loader 40, the Y-axis movable carriage 46 is moved along the Y-axis flame 26, the head 48 is moved along the Y-axis movable carriage 46, the pattern on the large screening print 28b is imaged by an upward camera unit 62, each imaging result is processed by a PC 50, and the processing result is displayed on the screen of the display device 52.

Description

technical field [0001] The present invention relates to a two-dimensional coordinate measuring instrument configured to photograph an object to be measured as an object, process the image obtained by the imaging, and measure the size of the object to be measured. Background technique [0002] As a two-dimensional coordinate measuring instrument, we have known a system that has an X-axis frame that is perpendicular to a Y-axis guide rail that is laid in parallel and is slidably arranged on the Y-axis guide rail, and moves the X-axis frame in the Y-axis direction along the guide rail. A Y-axis drive unit, a detection unit movably arranged along the length direction of the X-axis frame, an X-axis drive unit that moves the detection unit in the X-axis direction along the X-axis frame, and an irradiated object from below or above the detection unit The light source of the object to be measured is a device that moves a detection unit in two-dimensional directions to detect the siz...
