  • Patent number: 7712664
    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.

  • Patent number: 7505160
    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.

  • Publication number: 20060156234
    Abstract: One aspect of the current invention is related to updating an electronic source file based upon the edits made on a recording medium such as a print out. In other words, after the content of the source file is printed on a sheet of paper, when any edit is made to the printed sheet, the edit is automatically incorporated into the original source file without any human intervention to identify the edit or the original source file.

  • Patent number: 6935565
    Abstract: An imaging method includes the steps of (a) determining whether an object on which an image is to be formed is an information display medium on which a code is formed with an imaging material formed of a near infrared absorbing pigment, and (b) forming the image on the object by a printer engine with an imaging material formed of a pigment absorbing no or little light in a near infrared spectral region if the step (a) determines that the object is the information display medium.

  • Patent number: 6622787
    Abstract: A defroster/face cool air passage for introducing cooled air from an evaporator to a defroster opening portion and a face opening portion by bypassing a heater core, and a foot cool air passage for introducing cooled air from the evaporator to a foot opening portion by bypassing a heater core, are formed independently from each other. The foot cool air passage is located at sides of the heater core in a vehicle right-and-left direction. The cooled air from the foot cool air passage is mixed with warmed air having passed through the heater core at an inlet of the foot opening portion. Accordingly, pressure loss at a foot mode in an air conditioning unit with a central installation layout is reduced, and a mounting performance on a central portion of a vehicle instrument panel is improved.

  • Patent number: 5701949
    Abstract: According to the present invention, in an automotive air conditioner system, a link mechanism is provided by using a cool air passage provided in parallel with a warm air passage and a cool air/heated air mixing chamber provided at a downstream side of the warm air passage and the cool air passage. The clearance between a sliding door and a cooler can be set to a minimum distance as required. Further, it is not necessary to ensure a space for installing the link mechanism outside the case of the air conditioner. As a result, the size of the air conditioning unit including the sliding door can be effectively reduced.
