An apparatus for inspecting a display board or a circuit board in which an inspection terminal 4 of an inspection probe block B is pressed into contact with an electrode pad 3 of a display board or a circuit portion P for inspection. A probe block supporting frame member 2 has an expandable and contractible structure, and when the probe block supporting frame member 2 is expanded, a board supporting frame member 1 can be relatively advanced. Due to the relative advancement of the board supporting frame member 1, the display board or the circuit board P protrudes forward of a distal end of the terminal 4 of the probe block B through an enlarged opening area 16 of the probe supporting frame member 2, so that the display board or the circuit board P supported on the board supporting frame member 1 can be exchanged with another board.
