Abstract

PURPOSE:To obtain an automatic inspecting machine which does not require a transporting device such as a belt conveyor by slanting a plate, which has a hopper part, an inspection part, and a defective sorting part, forward and backward, and left and right to the machine body, and then transporting a printed wiring board by gravity force. CONSTITUTION:When an inspection start switch is pressed, a feeding means 19 operates to feed only one printed wiring board 15 to an inspection part 17 through an extruding plate 21. The wiring board 15 is run through a roller 38 at an initial speed and also slides on an inclined plane by its own weight while applied with gravity force to reach an inspection part 17, where it meets a stopper 32 and stops at the prescribed position of an upward and downward moving plate 26. Then, the upward and downward moving plate 26 is moved up to allow the printed wiring board 15 come into contact with a contact stylus. After inspection, the upward and downward moving plate 26 is lowered to the level of the inclined plane surface. Then, the wiring board is applied with the gravity force to slid on the inclined plane by its own weight and is also applied with transporting force by a roller 38 to move to a defective sorting part 18. Thus, the printed wiring board which moves by its own weight is stopped from moving forth by the stopper, so it stops at the prescribed position accurately.
