ABSTRACT:
An apparatus is disclosed which serves to insert and/or remove printed circuit boards into and out of slotted change pallets which are adapted to hold printed circuit boards in a generally vertical orientation and out of contact with each other. A roller conveyor is provided for conveying each printed circuit board in a horizontal orientation into a pivoted board holder or gripper, which is adapted to grip the printed circuit board preferably at its leading edge and to move the printed circuit board to a position in which the printed circuit board is substantially vertical and disposed over one of the slots formed in a change pallet that has been positioned below the board holder or gripper. The board holder or gripper is adapted to perform an outward pivotal movement from the bottom edge of the generally vertical board as the change pallet is advanced further.
