Abstract

PURPOSE:To reduce the size of an inspecting device, to simplify the device and to shorten the inspecting time of the device by moving a semiconductor device via a feeding mechanism, projecting a light to the end of a lead, photodetecting the light by a sensor, and judging the counted value of a counter. CONSTITUTION:A semiconductor device 1 is set on rails 8, is moved via a feeding mechanism, and the light from a light source 3 is projected via a reflecting mirror 4 to the end of the lead 2 of the device 1. The projected light is interrupted at every passage of the lead 2 (not bent) at the normal position, is received by a sensor 5, and is counted in number by a counter 6. This counted value is judged by a discriminator 7, thereby inspecting the presence or absence of the bent of the lead. In this manner, the bents of the lead can be inspected by a conveyor line with a small-size and simple device, thereby shortening the inspecting time.
