Abstract
A conveyor apparatus for a plate form article such as a lead frame including a main conveyor line and a working conveyor line for conveying the lead frame in a direction parallel to the length wise direction of the lead frame, and a sub-conveyor which transfers the lead frame to and from the main and working conveyor lines in a direction perpendicular to the conveyor lines, and the sub-conveyor being made of work-holders for holding the lead frame in such a manner that two ends of the length-wise direction of the lead frame are positioned perpendicular to the conveying direction of the sub-conveyor, a vertical driving cylinder for raising and lowering the work-holders, and a conveying mechanism, which includes a motor 61, timing belts, etc., for moving the work-holders in a direction perpendicular to the conveyor lines. Thus, a smooth conveyance of the lead frame by the sub conveyor is insured even though the lead frame has projected portions that are called "islands."
