Abstract
An apparatus for measuring contour configuration of articles, particularly brittle articles such as ceramic honeycombs without touching them comprising a turn table on which the article to be measured is placed, a rotary encoder mechanically coupled to the turn table for producing a rotational angle signal representing a rotational position of the article on the turn table, a lamp for illuminating the article on the table, particularly a portion of article to be measured such as an upper edge or side edge, a pick-up device including a lens for forming an optical image of said portion of article and an image detector such as a linear array of image sensor for converting the optical image into a picture signal, a memory for storing a standard picture signal which will be produced by the image detector when a standard article having given dimensions placed on the turn table is scanned during a single rotation thereof, and an operation circuit for receiving the rotational angle signal from the rotary encoder, the picture signal from the pick-up device and the standard picture signal from the memory and comparing these picture signals under the control of the rotational angle signal to …
