Abstract: A sheet conveying device includes a conveyer to convey a sheet and a primary sheet guide, disposed downstream from the conveyer in a sheet conveyance direction, to guide the sheet conveyed by the conveyer in the sheet conveyance direction. A secondary sheet guide is disposed opposite the primary sheet guide and includes a bending portion to bend the sheet while the sheet slides over the bending portion to change the sheet conveyance direction. A sheet conveyance path is defined by the primary sheet guide and the secondary sheet guide. The primary sheet guide includes a cavity disposed opposite the sheet conveyance path and a communication through-hole communicating with the cavity and the sheet conveyance path. The communication through-hole is disposed opposite the bending portion in a direction perpendicular to the sheet conveyance direction.

Abstract: A CPAP system includes a PAP device (5) structured to generate a supply of pressurized air, a patient interface (15) adapted to engage with the patient's face to provide a seal, an air delivery conduit (102,104) provided between the PAP device and the patient interface to deliver the supply of pressurized air along a gas delivery path from the PAP device to the patient interface, and a muffler (100) provided along the gas delivery path downstream of the PAP device.

Abstract: A portable printing cabinet having a housing with a substantially enclosed interior and an opening formed in a side surface thereof, a printing device located within the interior of said housing, and a paper tray positioned outside of the housing and in communication with the opening of the housing is provided.

Abstract: An ink-jet printer for ink-jet printing onto a print media. The printer has an ink-jet cartridge for ejecting ink onto a print medium during printing operations. A rotating drum platen holds a print medium on an outer surface thereof, the drum platen having an interior volume defined therein and an end wall extending transversely to the outer surface. A carriage holds the cartridge in a closely arranged position relative to the external surface of the drum. A drum drive apparatus rotates the drum to move the print medium in relation to the printhead of the cartridge. The printer further has a printer controller mounted in a fixed position relative to a printer chassis, and an electronic circuit disposed in the interior volume of the drum platen. A data communication link passes data between the printer controller and the electronic circuit.

Abstract: According to a method and apparatus for recognizing a paster portion of a web, each pixel data of a printed matter serving as a reference is stored as reference image data. Each pixel data of a printed matter serving as a test target printed on the web is stored as test image data. The reference image data is compared with the test image data in units of pixels to detect defective pixels. The paster portion of the web is recognized on the basis of a generation pattern of the defective pixels.

Abstract: Disclosed is a portable tape reader characterized in that a lid provided with a handle is integrally formed on the upper portion of a body provided with a reading head, the body is contained in a container box so that the body can be drawn out upwardly, and when the body is drawn out, the container box is held in the lower portion of the body and an opening of the container box is located below the reading head. In the portable tape reader having the above-mentioned structure, a tape which has been read is securely received and stored in the container box.

Abstract: The invention relates to apparatus for use in printing devices for the deposit of sheet-type recording media transported across a platen into a deposit tray area disposed above the platen. Deposit of the sheets is carried out by means of transport or delivery rollers which seize each sheet after it has passed through a printing area adjacent the platen and lift the sheet over a lower edge of the deposit tray for stacking. A pivotally mounted common carrier bracket is provided to carry a support wall which forms the lower edge surface of the deposit tray and the transport roller means. The support wall has a stripper surface formed along one end thereof containing bias means for resiliently pressing the recording medium into driving engagement against the transport rollers. The other end of the support wall is formed with intake guide surfaces for leading sheets into engagement with the intake side of the platen.

Abstract: A lightweight, extremely compact printer apparatus has a constant speed drive which imparts reversible, translatory motion to a print head; and as the print head is advanced with respect to a platen imparts a direct mechanical drive to a paper advancing roller in order to advance paper from a feed roll line by line between printing operations. In turn, advancement of the paper or other recording medium from the paper roll drives a print ribbon supply holder to advance a print ribbon across the platen in front of the paper. The power requirements and size of the apparatus are substantially reduced to the extent that the apparatus is of a size corresponding to hand held calculator printers, since the movement of each element is utilized to drive another element successively from the print head carrier, paper advancement roller, paper roll to the print ribbon in close correlation to one another during each print cycle.

Abstract: A facsimile transceiver comprising a document/copy receiving drum, a motor for rotation of the drum about the drum axis and a read/write head mounted for linear movement in a direction parallel with the drum axis. When the transceiver is operating in the receive mode, the copy medium having adhesive along at least one edge circumscribes the drum in a closed loop so as to eliminate the necessity for transmitter-receiver angular synchronizing signals which would otherwise be required for locating the copy margin adjacent the edge of the copy paper. After completion of a transmission, the copy medium is severed along a line so as to provide an appropriate margin for the copied information content. The copy medium may comprise a magazine having a plurality of sheets of a copy medium which form individual closed loops where one edge of each sheet overlaps with and is attached to the opposite edge of the sheet.

Abstract: Paper feeding and handling apparatus, especially for a facsimile receiver, including a cradle for supporting a roll of paper and for raising and lowering it to permit handling of the roll. Roll and guide means lead the paper from the supply roll to a writing station which also includes sheet-cutting means. A sheet-handling tray is disposed to receive the written and cut sheets, and various mechanical means are provided to feed and support the cut sheets.
