板検査装置。[Scope of Claim for Utility Model Registration] On a jig that has a fixed pin and a probe pin for printed circuit board inspection that are erected and fixed on the top surface, and a floating pin that is vertically movable on the top surface,
A printed circuit board having a hole at a predetermined location corresponding to the fixing pin is inserted into the hole to position the printed circuit board, and then the printed circuit board is placed on the floating pin and pressed to move it up and down above the printed circuit board. In a printed circuit board inspection device in which the probe pin is brought into contact with the back surface of the printed circuit board by pressing down the printed circuit board and the floating pin with the body, the normal position of the floating pin and the operating position when the floating pin is pressed down by the printed circuit board. What is claimed is: 1. A printed circuit board inspection apparatus comprising: a detection switch for detecting the detection switch; and a drive circuit for controlling the vertical movement of the pressing body based on a detection signal from the detection switch.
