PURPOSE:To suppress the cost by furnishing a loading device, which is capable of lifting each of works from their set position and returning onto a pallet situated in the loading position, and thereby enhancing the operational efficiency of the processing machine. CONSTITUTION:In a processing machine to bore a number of holes in a printed circuit board, the mechanical operation can be carried out continuously until all of the works III placed on 15 pallets IV in a pile are processed completely, and this continuous operation is completed when a frame VI accommodating the pallets IV with processed works III has attained the upper limit position in a storage V. Accordingly the processed works III can be taken out at one time. The emptied frame VI is returned to the sunk position to accommodate again pallets IV with unprocessed works III. Thus the operation can be made mechanically and continuously until the processing is completed. According to this arrangement, the operational efficiency will be enhanced and the cost suppressed. |
