A method and apparatus for inspecting appearance of articles while they are transported on a conveyor by reflecting images of four different side surfaces of the article being by means of a plurality of reflecting means arranged above and at both sides of a conveying path on the conveyor to transmit the four images onto a sensor surface of a sensor camera, reflecting an image of a top surface of the article onto the sensor surface of the sensor camera in the array with the four images, and scanning and photographing the images of five different surfaces of the article formed on the sensor surface of the sensor camera by the sensor camera at every preset amount of movement of the article synchronized with the conveyor, and processing the photographed images so as to measure and inspect the form, size and surface conditions of the article by using only one sensor camera at the same time. The method and apparatus can reliably cover five of the six partial surfaces, front and rear, right and left, and upper and lower, of an article, that is, 5/6=83 % of the whole surface of an article in the inspection of surface conditions.
