Abstract: A 2-dimensional code reading apparatus includes a code position detector receiving an input image that is formed by optically reading 2-dimensional codes, and extracting a 2-dimensional codes from the input image. A data acquisition unit acquires identification information of a document page and positional information of the 2-dimensional codes on the document page, from the 2-dimensional codes. A data decoder performs decoding of the identification information and the positional information. The code position detector is provided with a code frame detector detecting a code frame which defines a fixed region of the 2-dimensional codes, and determining a dot of a target pixel as being a corner dot of the code frame.

Abstract: A paper identification information management system includes a client apparatus that handles a sheet of paper bearing prescribed information, and a management server connected to the client apparatus via a network to comprehensively manage information about the paper handled in the client apparatus. The client apparatus transmits a paper ID request and document information to the management server via the network when carrying out a printing operation. Based on the paper ID request and the document information, the management server assigns a paper ID to each sheet of paper handled by the client apparatus. The management server then transmits the paper IDs to the client apparatus, and simultaneously, records the assigned paper IDs in association with the document information.

A controller controllably drives the separating and feeding device and conveying device. The controller drives the conveying device by controlling the time interval between the restart of conveyance of the preceding document and the restart of conveyance of the following document.

Abstract: An automatic original document feeding device which can shorten a length of time required for refeeding sheets of the original document after a jamming of a sheet of the original document is cleared. When a trouble signal is received indicating that a sheet of the original document remains within a feed path due to an improper feeding or a jamming before the sheet is completely scanned, a side cover is opened and at the same time a driving mechanism is actuated for automatically lowering the sheets of the original document from a feeding position. If the jamming occurs at a later position in the paper path after the image has been completely scanned, the side cover does not have to be opened, the driving mechanism is not lowered, and the sheets of the original document remain in their feeding position.

Abstract: A rolling piston type expansion machine eliminates the need for an open-close valve mechanism and smoothens the timing of inflow of high-pressure gas. The machine includes a cylinder having a discharge port and a roller freely gyratable or orbital in the cylinder. A freely movable blade supported in the cylinder has its tip in contact with the circumferential surface of the roller to form an expansion chamber. A gas passage is freely rotatably supported by a main bearing member and a secondary bearing member. The gas passage is formed in a main shaft having a crank shaft portion that gyrates or orbits the roller. An inlet port is provided along a shaft center of the main shaft. An inflow timing control portion controls inflow timing of the suction gas toward the expansion chamber via the inlet port of the gas passage.
