  • Patent number: 10674024
    Abstract: An assisted scanner is ergonomically positioned in the bottom of a specially equipped MFP where the scanner is accessible to a user's feet by being housed in a housing drawer extensibly/retractably carried on slides in the bottom of the MFP. Instead of the scanner cover itself retaining a to-be-scanned document on the scanning-unit platen, the scanner cover is laterally slidable off from/onto the platen. Specially configured bar clamps as document holders, pivoting on motorized hinges, are provided flanking the platen. The document holders assume the function of pressing down on the document to retain it on the platen. The motorized hinges are voice-actuatable via a voice-user interface. The assisted scanner may be part of a system including wield-assist sandals, the sole of one, but not both, of which is coated with a low-tack adhesive whose adherence is easily breakable.

  • Patent number: 7051653
    Abstract: An image recording material separating/removing device which, by using a single lift-out mechanism section, can lift image recording materials out from plural cassettes along simple loci of movement, and in which a space for providing and withdrawing the cassettes is kept as small as possible. In a cassette housing section, a plurality of cassettes are disposed one above another. Each cassette is offset in a horizontal direction. An amount of offset is set on the basis of a locus of movement of a printing plate at a time when the printing plate is sucked and held by suction cups and lifted up in a vertical direction. At least while the suction cups are moving in the vertical direction, the printing plate is not interfered with by cassettes thereabove, and an emulsion surface of the printing plate is not scratched. Space required for placement of the cassette housing section can be reduced. Moreover, because movement of the suction cups can be simplified, a control system can be simplified.

  • Patent number: 6823791
    Abstract: A substrate manager for a substrate exposure machine is used, in one example, as a platesetter. As such, it comprises a substrate storage system, containing one or more stacks of substrates, such as plates in one implementation. A substrate picker is provided for picking substrates from the stack of substrates. The substrates are then handed to a transfer system that conveys the substrates to an imaging engine. According to the invention, a substrate inverter system is also provided. This system inverts the substrates from being imaging or emulsion side down to emulsion side up in the present implementation. This allows plates, for example, which are stored emulsion side down in cassettes to be flipped to an emulsion side up orientation, and then transferred, using the substrate transfer system to the imaging engine. This flipping process has two advantages. First, the plates can be emulsion side up during the transfer. This prevents any damage to the sensitive plate emulsions.

  • Patent number: 6739261
    Abstract: A device for selecting and conveying printing plates is provided which can overcome complexity of work involved in so-called batch processing, and can realize operation of, for example, removing a printing plate from a cassette in a small space, such that operation efficiency can be improved and less space is required. Cassettes other than a lowest cassette are independently supported on sliding bases. The sliding bases move (slide) on rails with hardly any frictional resistance. The rails extend to a cassette withdrawing space section provided adjacent, and unnecessary cassettes are moved horizontally along the rails. Thus, a printing plate can be removed from a needed cassette at a reference position without the needed cassette being moved at all. In this way, there is no need to provide, at each cassette, space for removing the printing plate, and no need to move a printing plate removing device to positions at which the cassettes are disposed.
