  • Patent number: 9967415
    Abstract: An image reproduction device having a movable frame with a central aperture and an extendable soft cover. The soft cover can be extended from a storage position to at least partially span a platen and cover three dimensional objects resting on the platen. The frame can be lowered to seal the soft cover over and around the object and platen, such that it blocks light transmission into and out of the image reproduction device during scanning.

  • Patent number: 9004488
    Abstract: A conveying apparatus includes a first pair of rollers having a drive roller and a pinch roller driven by the drive roller, a second pair of rollers provided downstream of the first pair of rollers, and an arm member supporting the drive roller and adapted to be swingable such that a force for pressing the drive roller against the pinch roller increases as a conveyance resistance of the sheet increases. The force for pressing the drive roller against the pinch roller decreases if driven by the moving sheet. The conveying speed of the second pair of rollers is set to be higher than the conveying speed of the drive roller so as to cause the drive roller to be driven by the sheet in the case where a skew of the sheet has been corrected and the sheet having the skew corrected is conveyed by the second pair of rollers.

  • Patent number: 8672320
    Abstract: A recording-material transport apparatus includes a retracting member that moves at a speed lower than a transport speed of a recording material transported from an upstream side in a transport direction, to a downstream side in the transport direction along a transport path for the recording material, and that retracts from the transport path after a leading end of the recording material contacts with the retracting member, a first transport member that transports the recording material from the upstream side in the transport direction toward the retracting member, and a second transport member that further transports the recording material in contact with the retracting member to the downstream side. After the leading end of the recording material contacts with the retracting member, without being paused, transport of the recording material with the first transport member is continued to deliver the recording material to the second transport member.

    Abstract: A paper deskew device for an automatic document feeder includes a transport roller assembly, a deskew roller assembly, and a power transmission mechanism. The transport roller assembly includes a first gear. The deskew roller assembly includes a second gear. Before a front edge of a paper is contacted with the deskew roller assembly, the first gear links the power transmission mechanism and the second gear, so that the transport roller assembly and the deskew roller assembly are respectively rotated in a first direction and a second direction. Once the front edge of the paper is contacted with the deskew roller assembly, the deskew roller assembly is continuously rotated in a second direction for a second direction for correcting the skew phenomenon of the paper. Afterwards, the second gear and the deskew roller assembly are driven by the first gear to be rotated in the first direction to transport the paper.

  • Patent number: 8123215
    Abstract: In a sheet aligning apparatus, a sheet is conveyed from a conveying-in path into a sheet storing section through an open end portion and the leading end of the sheet comes in with a stop member. Thereafter, when a shifting section shifts the stop member from an initial position to a first position, the sheet is shifted inversely together with the stop member and the back end of the sheet proceeds as the inversed leading end from the open end portion to a conveying-out path so that a succeeding sheet is allowed to be conveyed from the conveying-in path into the open end portion. When the sheet is shifted inversely, a shift regulating section regulates the shift of the sheet in such a way that the back end of the sheet is prevented from proceeding more than a predetermined distance due to the inertia of the shift.

    Abstract: A transfer wheel removes flat products from one location, such as an overhead conveyor, spaces the products apart, reorients them and then transfers the products to a second conveyor or other location. The transfer wheel is eccentrically mounted within a circular frame. Grippers mounted on radially-moving spokes of the transfer wheel rotate as the wheel turns, to reorient the products, for example from vertical to horizontal, so they can be laid flat on the second conveyor. The eccentric mounting of the wheel causes the spokes to increase the spacing between adjacent products as the wheel turns, to prepare the products for later processing.

  • Patent number: 6805347
    Abstract: The skew of a sheet of print media is precisely controlled by intentionally inducing print media deformation, so that cooperative mechanical and gravitational forces may be used to align the leading edge of the sheet. The sheet is driven into a nip region of deskew rollers in a manner that causes the print media to deform, lifting a movable member in a direction substantially perpendicular to the feedpath into the nip region. The movable member applies a return force that is generally equal along a widthwise surface region of the print media. As a result, there is a reduced likelihood that the print media will be skewed relative to the nip region. In some applications, the return force is adjustable.

  • Patent number: 4046369
    Abstract: A machine for feeding inserts, for example, newspaper advertisements, to a device which separates or orients the inserts into a shinglelike arrangement and delivers them to a device which inserts them into the main portion of the newspaper. An oscillating or vibrating plate is utilized which moves into and out of the flow path of the inserts to strike the inserts from a direction which is perpendicular to the path of movement thereof to gradually orient the inserts as they move along a conveyor belt toward the separating device. A diaphragm plate effects the proper separation of the inserts prior to their delivery to the device which effects an insertion of the insert into the main portion of the newspaper.

  • Patent number: 4026542
    Abstract: Apparatus for registering a pair of rectangular sheets includes a rectangular sleeve whose width is variable, and a retractable gate located at one end of the sleeve. In a first embodiment, fluid injected into the other end of the sleeve provides first and second fluid streams which register one of the sheets with the gate and one of the narrow walls of the sleeve, and register the other of the sheets with the gate and the other narrow wall of the sleeve. In a second embodiment, the sheets are registered against a centrally disposed vented manifold and the gate. In a third embodiment, fluid drawn into the sleeve provides first and second fluid streams which register one of the sheets with the gate and one of the narrow walls, and register the other of the sheets with the gate and the other of the narrow walls.

  • Patent number: T102003
    Abstract: The method and apparatus aligns the leading edge of pliable sheet material such as paper, transverse to its intended direction of travel. Feed means positively advances the material between guide members towards an alignment member pivotally mounted but releasably secured by a latch means in the plane of the desired leading edge orientation for the sheet material. Position sensing means adjacent the alignment member senses proper leading edge orientation. The latch means responds to the position sensing means operation to release the alignment member and sheet material for movement towards transport means adapted to positively engage the sheet material leading edge to convey the properly orientated sheet material.In a typical configuration, the feed means is a set of feed rollers, the alignment member is a pivotally mounted mechanical gate assembly, and the leading edge alignment sensing means is a mechanical trigger member or photoelectric sensing means.
