Patent ID: 8028609

Claim:
A work sheet processing system, comprising: a work sheet processing machine that performs a processing operation of cutting a product work sheet from a material work sheet; a redundant work sheet stocker that stores a redundant work sheet, the redundant work sheet being a remaining part of said material work sheet from which said product work sheet has been cut by said work sheet processing machine; and a carry-in and carry-out means for carrying out said redundant work sheet from said work sheet processing machine to said redundant work sheet stocker, and for carrying said redundant work sheet from said redundant work sheet stocker to said work sheet processing machine, wherein said redundant work sheet stocker includes a plurality of work sheet supports disposed a different vertical positions, each of said plurality of work sheet supports being capable of supporting at least one redundant work sheet by direct contact, the plurality of work sheet supports being attached to an elevating and lowering member, wherein said carry-in and carry-out means comprises a work sheet holder that holds said redundant work sheet, wherein said work sheet holder moves while holding said redundant work sheet, wherein said redundant work sheet stocker is located on a side of and adjacent to said work sheet processing machine, wherein said redundant work sheet stocker can move said redundant work sheet in a predetermined carry-in and carry-out direction corresponding to a direction in which said work sheet processing machine and said redundant work sheet stocker are arranged, wherein said work sheet processing machine has a work sheet positioning mechanism that moves a work sheet to a processing head of said work sheet processing machine which performs said processing operation, and wherein said work sheet positioning mechanism can move said work sheet in said carry-in and carry-out direction.
