  • Patent number: 5980137
    Abstract: In a printer for facsimile machines or the like, a forward end of paper to be fed is temporarily fixed between a platen roller and a print head before printing by the print head is started. A paper feed roller is then rotated so that an inclination of the paper is corrected. Guides are provided so that the paper is fed in a direction of a tangential line of the platen roller at a holding point between the platen roller and the print head.

  • Patent number: 5961229
    Abstract: A ribbon cassette includes a lid member that is not abruptly opened when a cassette is loaded into a printing apparatus and/or a facsimile apparatus using the ribbon cassette. Retained parts are provided on both side faces of a supplying part main body of a ribbon supplying part in a ribbon cassette and retaining parts which are detachably engaged with the retained parts to retain a lid member by the supplying part main body are provided on side faces of the lid member. While each of the retained parts is a protrusion projecting sideward, each of the retaining parts on the side faces of the lid member via a hinge part and has an engagement hole with which the protrusion is detachably engaged.

  • Patent number: 5913621
    Abstract: The invention provides an ink ribbon cartridge which ensures proper, reliable mounting of an ink ribbon. The ink ribbon cartridge of the invention includes a pair of spools, an ink ribbon including a band-like sheet wound around the pair of spools and provided with a layer of ink formed on one surface thereof, four spindles which have disk-shaped sections at one end and can be placed, for a specific length in both ends of the pair of spools, and a cover covering the pair of spools around which the sheet is wound and having four round holes in which the disk-shaped sections of each of the spindles are loosely fitted. In one of the four ends of the pair of spools, only the other end of a specific one of the four spindles can be inserted for a specific length, and one of the four round holes formed in the cover is formed such that only the disk-shaped section on one side of the specific spindle can be loosely fitted.

  • Patent number: 5897256
    Abstract: The invention provides a recording apparatus capable of preventing deterioration of printing quality likely to be caused by ink ribbon creases. The recording apparatus uses a replaceable ink ribbon cartridge which has an ink ribbon wound on a take-up spindle and a feed spindle. A take-up spindle support section rotatably supports the take-up spindle when the ink ribbon cartridge is mounted in a specific position. The recording apparatus is further provided with a displaceable retaining member displaceable between a first position, for holding the take-up spindle between the take-up spindle support section and the retaining member to restrict the displacement of the take-up spindle, and a second position, for permitting movement of the take-up spindle into the take-up spindle support section.

  • Patent number: 5739925
    Abstract: A facsimile apparatus includes a main body frame, an operable cover plate for covering at least the front top of the main body frame, a separating roller for separating a document sheet attached to the main body frame and a document feeding mechanism for feeding a document sheet separated by the separating roller. All of the rollers in the document feeding mechanism are attached to the main body frame. Since all rollers of the document feeding mechanism are attached to the main body frame, it is not necessary that the cover plate have high rigidity. Consequently, the weight of the cover plate can be reduced, and the manufacturing cost of the cover plate can be reduced.

  • Patent number: 5604609
    Abstract: A facsimile machine has various detection devices. One of the detection device detects a sheet medium. The detection device includes a reflection type sensor directly mounted on a control board. An actuator is pivotally movably supported in a main frame of the facsimile machine. The actuator has a pivot shaft portion, a first arm and a second arm those extending from the pivot shaft portion. A free end of the first arm is abuttable on the sheet medium. If sheet medium is transferred to a predetermined portion, an edge of the sheet urges the free end to angularly rotate the actuator. A free end of the second arm is provided with a reflection member. The angular movement of the actuator causes the reflection member to be brought into confrontation with the reflection type sensor so as to detect passage of the sheet medium. A regulation member is integrally provided to the reflection member.

  • Patent number: 5519512
    Abstract: A facsimile apparatus includes a light emitting unit disposed downstream in the direction of feed of a document with respect to a normal plane perpendicular to the document surface on a reading line. Outgoing beams for reading travel rearward in a substantially horizontal direction. Incoming beams from the light emitting unit are reflected on the reading line on the document surface and are supplied as the outgoing beams for reading to a light sensing unit. Consequently, it is possible to reduce the height of the front portion of the facsimile apparatus so as to increase a degree of freedom in designing while enhancing reliability in reading the document.
