In a processing apparatus (10) for processing a work (1) while stopping the work(1) intermittently without affecting conveyance of the work (1) at respectiveprocessing positions (Pn-1, Pn+1) in the upstream and downstream, positionalprecision in processing of the work (1) is enhanced. The processing system comprisesa processing section (20) provided at a processing position (Pn) in order to performprocessing to the work (1) while the work (1) is stopped, an incoming side buffermechanism (34a) provided in the upstream of the processing section (20) in a predetermineddirection and capable of storing the works (1) conveyed from the upstream； anoutgoing side buffer mechanism (34b) provided in the downstream of the processingsection (20) in the predetermined direction and capable of storing the processedworks (1) which are to be conveyed downstream； and a delivery section (31b) fordelivering the works (1) stored by the incoming side buffer mechanism (34a) tothe processing section (20).
