A test head moving apparatus includes elevating arms that move a test head up and down, a frame that horizontally moves the test head, and an interlock mechanism that prohibits the horizontal movement of the frame on the basis of a height of the test head. The interlock mechanism has a limit switch that detects that the test head is positioned at the lowermost limit and stoppers capable of pressing the pressing units onto a floor plane. |
