PROBLEM TO BE SOLVED: To successively and safely push out printed circuit boards starting with the one placed at an innermost part when a plurality of printed circuit boards are arranged side by side in each stage of a printed circuit board accommodation rack. SOLUTION: The extrusion apparatus of printed circuit boards has extrusion means 2 where a press head 4 is mounted to the tip section of an extrusion member 3 that can advance and retreat in a horizontal direction, and allows the extrusion means to advance for extruding a plurality of printed circuit boards that are accommodated into the printed circuit board accommodation rack by the press head one at a time. In this case, the press head 4 is formed in a clip shape having upper and lower jaw sections 5 and 6 where press pieces 5A and 6A for pressing the printed circuit board are provided at the tip section. A translation cam mechanism 7 is provided between the upper and lower jaw sections, and is operated via an operation means 9 that is actuated and connected with the direct-moving cam mechanism, thus pushing up the press piece 5A at the upper jaw section by specific height with the tip section. |
