Abstract

PURPOSE:To enable to detect deficient shape such as broken, cracked and deformed tablets with good precision, by using the CCD linear array which scans orthogonally toward the moving direction of tablets. CONSTITUTION:The tablet T fed to the first hold drum 2 from the production process via the supply guide 1 is held at negative pressure at the circumference of the drum 2, and surface inspection is made by using the illumination lamp 4 located on the first inspection position 3, lens 5, and CCD linear array 6. The tablet judged as good quality is fed to the reception position 9 and held at the second tablet hold drum 10 with negative pressure, and inspection of back side is made at the second inspection position 11. The similar allocation as the first inspection position such as CCD linear array 14d is made even in the second inspection position 11, and the video signal outputted from the linear arrays 6, 14 is fed to the control processing circuits 7, 15 for the discrimination of propriety.
