PURPOSE:To miniaturize a PCB extruding device as small as the size of amplitude almost equal to the length of an extruding arm, by installing this extruding arm for a printed circuit board rockably within a vertical surface of the PCB in an extruding direction. CONSTITUTION:When a cylinder mechanism 10 gets moving toward an extruding direction A from a stand-by position where an extruding arm 15 is tilted to some extent, a screw rod 11 comes off a striking member 18 and is released from holding pressure. And, it is forcedly pressed to a bracket 9b by energizing force of a spring member 13. At his time, with its relative rectilibear motion with a sliding base 9 of a screw stock 11 commensurate to an initial gap lbetween the bracket 9b and the extruding arm 15, a collar member 14 is reversely rotated. In consequence, the extruding arm 15 goes down to a horizontal position within a vertical surface in the extruding direction A, and it comes into contact with a printed circuit board 1 from the rear, thus the PCB1 is kept in an extrusible attitude. Furthermore, with operation of the cylinder mechanism 10, the PCB1 is extruded in the specified size by the extruding arm 15. |
