An automatic inspection apparatus including a carrier body on the (Y, -) side which is slidably supported by X-direction guide rods, and a carrier body on the (Y, +) side slidably supported by both X- and Y-direction guide rods, each carrier body accommodating a plurality of tap shafts vertically movable therethrough, so that the tap shafts are raised and lowered as desired for the inspection of the object. Each carrier body houses a drive shaft operatively coupled to a prime mover for rotation. A plurality of screw gears, each of which is spring-biased in one way, are fitted on the drive shaft axially slidably thereon. These screw gears and tap shafts are operatively interconnected through gearings to raise and lower the tap shafts. In case of overloading on the load side, the screw gears are tripped against the spring forces so that the displacements of the screw gears can be detected. |
