Abstract

PURPOSE: To increase the accuracy of detection and to reduce the cost, by constituting a number of switches on the same plane.
CONSTITUTION: The base plate 8 is gradually lowered and the tip of the correction pin 4 is stopped when it adheres to the board 11. In this case, the length l1 of the part 4a having greater diameter of the correction pin 4, is made short by about 0.1mm than the length l2 of the part 3b having smaller diameter of the check pin 3. If no component 13 is present, the check pin 3 is not lifted up and the switch 2 makes short circuit between the electrode patterns. Thus, the absence of the component 13, i.e., the defect is detected.
