<P>PROBLEM TO BE SOLVED: To provide a disk image acquisition device capable of easily and accurately acquiring a taken image of a whole pattern formed on a disk surface of multiple types of disks with different diameters. <P>SOLUTION: A disk image acquisition device comprises: a guide body that guides a peripheral surface of a disk moving in a predetermined direction, along a predetermined guide line; an imaging window that determines an image-taking area on one surface of the disk; an imaging timing sensor that includes a detection axis line crossing a moving direction of the disk and outputs a timing signal under the assumption that the disk reaches a predetermined position of the imaging window when the peripheral surface of the disk is detected on the detection axis line; and an imaging unit that images one surface of the disk through the imaging window on the basis of the timing signal. With setting a bisector of an angle formed by the guide line and the detection axis line when looking from a direction perpendicular to the imaging window as a baseline, the imaging window extends along the baseline. <P>COPYRIGHT: (C)2013,JPO&INPIT |
