<P>PROBLEM TO BE SOLVED: To provide a tablet inspection device that significantly improves accuracy of visual inspection on tablets during manufacturing a PTP sheet, and to provide a PTP packaging machine. <P>SOLUTION: The tablet inspection device 21 includes a lighting device 22, a camera 23 and an image processing device 24 and the like. The amount of light emitted to a tablet from the lighting device 22 is gradually changed to image the light transmitting the tablet using the camera 23, thereby obtaining multiple patterns of luminance image data. The luminance values of each coordinate in the multiple patterns of luminance image data are added up to create three-dimensional data related to the surface of the tablet. The tablet is visually inspected on the basis of the three-dimensional data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
