PURPOSE: A machine vision system using a polarization film is provided to perform diversified small-quantity production by arranging holes basically formed on both ends of a PCB. CONSTITUTION: A transfer device(150) transfers a PCB by vacuum absorbing or clamping the PCB. The transfer device is located within the range of photographing of a camera module(100). The light from an LED(109) is intensively emitted to the range of photographing. The camera module includes a camera, a lens, a polarization film fixing unit, a polarization film and a light emitting unit. The location control device manually controls the location of the camera module. [Reference numerals] (100) Camera module; (105) Camera; (140) Controller; (150) Transfer device
