ABSTRACT:
An inspection device of a tape reel comprises a first inspection device10consisting of a light projector11, a mirror12, and a light receiver13, a second inspection device20consisting of a light projector21, a mirror22, and a light receiver23, and a rotator30that rotates a tape reel40, and parallel lights R1, R2irradiated from the light projector11are reflected by the mirror12, to be made incident on inner surfaces of flanges42, 43of the tape reel40, whereas parallel lights R3, R4irradiated from the light projector21are reflected by the mirror22to be made incident on the inner surfaces of the flanges42, 43of the tape reel40, and parallel lights R1to R4that pass the inner surfaces of the flanges42, 43are received by the light receiver13or the light receiver23. Thereby, an inspection device capable of inspecting a position of each flange of the tape reel, distance between flanges, and an inclined angle of each flange in a un-contact state accurately at high speed, an inspection method for the same, and a positioning device of a member to be positioned capable of positioning the position of the flange accurately are provided.
