Abstract: PURPOSE: To obtain an automatic inspection apparatus which performs inspection automatically and with good efficiency without relying on a manual operation by holding a semiconductor element in a slit on an inspection disk and performing the characteristic test, acceptance/reject judgment, and accepted products sorting operation of the element to be inspected while the inspection disk makes a round. CONSTITUTION: When one element 7 to be inspected is fed to a slit 6a by means of a feeder 8, it is detected by an element detection sensor 13, a servomotor 6a is started by an instruction from a control part, and an inspection disk 6 is operated and controlled so as to be fed at a constant pitch in a constant direction. When the element 7 which has been housed and held in the slit 6a reaches characteristic inspection positions #1, #2, #4, tester electrodes 9a, 9b are brought into pressure contact with electrode faces at both ends of the element 7, a P or N polarity check, a forward voltage/current characteristic and a reverse-recovery- time characteristic are tested, test data is sent to the control part, and an acceptable product and a product to be rejected are judged by an acceptance/reject judgment part.  An NG element which has been judged as the product to be rejected is discharged from the slit by NG-element discharge parts #3, #5, and only the acceptable product is collected from an acceptable product collection part #6.
