PURPOSE:To attain labor saving, by providing a first push-away means for pushing away a board multistage parallel arrangement body to the side opposite to a connector and an arm with a second push-away means for pushing away said arrangement body to the connector side to a rotary shaft arranged at a constant position. CONSTITUTION:A rotary shaft 6 forms a pair in the left and right and the arm 7 corresponding to the multistage parallel arrangement body of a test board 1 is mounted to the shaft 6 and first and second push-away means 8, 9 are respectively provided to the arm 7. When the shaft 6 is revolved and displaced to a required direction, the push-away means 8 coming to the engaging step part of the arm 7 is impinged on the projection P provided to the back surface of the board 1 by the displacement of the arm 7 to a second position accompanied by the shaft 6 and the arm 7 is displaced to the second position. By this method, the board 1 is detached from a connector and the means 8, 9 occupy a position out of the advance path range at the time of the entry and exit of the board 1 with respect to the chamber and the multistage parallel arrangement body of the board 1 can be fed out from the chamber without being obstructed by the means 8, 9. By this method, labor saving is attained.
