Abstract

PURPOSE:To improve detecting accuracy by specifying a method of radiating and receiving light. CONSTITUTION:A projector 9 is arranged upward aslant to an inspection position, a parallel flux of light with a required width is radiated on the outer side wall 1a of an inspecting bottle 1 and a light receiver 10 is arranged facing the bottle at the angles of 30-45 degrees under a corner wall part 1c of the bottle 1. Thus when the bottle 1 fed on the conveyor 3 is brought to an inspection position by star wheels 4, a plug 5, the bottle is given one rotation by a friction wheel 7 in the center of rotation of the bottle, the parallel flux of light 2 from the projector 9 reaches the corner wall part 1c through the side wall part 1a, is reflected here, caught by the light receiver 10, converted into a measuring signal g, compared with a reference measuring signal g0 by a comparator 13 after amplification, while a detecting signal K is input from a position detector 8 to a discriminator 14. When a higher measuring signal than the reference measuring signal g0 is input, the output signal T shows the existence of a crack 1.
