no. 2 Embodiment approach

[0073] Next, a second embodiment will be described. Figure 9 It is an explanatory diagram of image analysis of the position correction tool 201 of this embodiment. Such as Figure 9 As shown, the position correction tool 201 of this embodiment is formed into a cylindrical shape, and has a side surface 211, a bottom surface 212a (first transmission part) and a bottom surface 212b (second transmission part) at both ends of the cylinder. ). A flange portion 215 is provided on the side portion 211 . The bottom parts 212a and 212b are the same member, and the thickness of the bottom part 212a is formed to be thinner than the thickness of the bottom part 212b. As the material for the bottom parts 212a and 212b, it is conceivable to use a material that transmits X-rays to a certain extent and can be easily processed, for example, aluminum or resin. A circular hole 213a is formed in the bottom portion 212a. A circular hole 213b is formed in the bottom portion 212b. The diameter...

no. 3 Embodiment approach

[0081] Next, a third embodiment will be described. Figure 10 It is an explanatory diagram of image analysis of the position correction tool 301 of this embodiment. Such as Figure 10 As shown, the position correction tool 301 of this embodiment is molded into a cylindrical shape, and has side parts 311, bottom parts 312a (first transmission parts) and bottom parts 312b (second transmission parts) at both ends of the cylinder. department). A flange portion 315 is provided on the side surface portion 311 . The bottom parts 312a and 312b are the same member, and the material of the same thickness can be used. A hole 313a is formed in the bottom surface portion 312a. The hole 313a has a shape such as a small circle at the center and a cross-shaped groove extending around it. A circular hole 313b is formed in the bottom portion 312b.

Abstract

An object of the present invention is to provide a position calibration tool and an X-ray position measuring device capable of quickly and accurately adjusting the emission center of an X-ray emitter and the optical axis of an X-ray camera. The tool for position correction of X-ray position measuring device is used to capture an image based on X-rays emitted from an X-ray emitter with an X-ray camera and emit X-rays from an X-ray position measuring device that measures an object to be measured The X-ray emission center of the X-ray emitter is aligned with the optical axis of the X-ray camera, wherein the position correction tool has: a first transmission part that transmits X-rays emitted from the X-ray emitter side; and a second transmission part. a part that transmits the X-rays transmitted through the first transmission part and projects the X-rays to the X-ray camera, and the position correction tool uses the first projected image based on the X-rays transmitted through the first transmission part, and A second projected image based on the X-rays transmitted through the second transmission unit is projected to the X-ray camera.

Description

technical field [0001] The present invention relates to a tool for position correction and an X-ray position measuring device. Background technique [0002] An X-ray position measurement device that measures the position of a printing plate using an X-ray emitter and an X-ray camera is known (Patent Document 1). In such an X-ray position measuring device, when the emission center of the X-ray emitter does not coincide with the optical axis of the X-ray camera, distortion occurs in an image captured by the X-ray camera, and accurate positioning cannot be performed. Therefore, in such an X-ray position measuring device, adjustment is performed so that the emission center of the emitter coincides with the optical axis of the X-ray camera. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-88170 [0004] In this way, when adjusting the emission center of the emitter to coincide with the optical axis of the X-ray camera, it is hoped that the adjustment will not dela...
