Aligning At Stack Patents (Class 271/3.02)
  • Patent number: 9505572
    Abstract: Aspects provide for a printer with automatic paper sheet count discovery, via determining an initial weight of printer paper sheets within a printer paper feeder tray. A single sheet is removed from the paper feeder tray to a staging area of the printer, and a revised weight is determined for the sheets within the paper feeder tray while the single sheet of paper is removed to the staging area. The single sheet is fed back into the paper feeder tray via a printing path bypass of the printer. The weight of the single sheet determined as a function of the difference between the initial weight and the revised weight. A quantity of printer paper sheets currently loaded within the paper feeder tray and available to satisfy a print job is determined as equal to the initial weight divided by the weight of the single sheet.

  • Patent number: 8814157
    Abstract: A sheet processing apparatus includes a sheet stacking unit where sheets to be processed are stacked, a regulating member, a sheet waiting unit, a first moving unit, a second moving unit, and a control unit. The regulating member abuts on one edge of sheets conveyed to the sheet stacking unit. The sheet waiting unit keeps sheets waiting, stacks the waiting sheets displaced sequentially, and then conveys the sheets to the sheet stacking unit. The first moving unit sequentially moves the conveyed sheets, starting from a lowermost sheet, to be abutted against the regulating member. The second moving unit moves the conveyed sheets to the first moving unit. The control unit controls a moving speed of the second moving unit so that a next sheet does not reach the first moving unit until the sheet moved by the first moving unit is abutted against the regulating member.

  • Patent number: 7828281
    Abstract: When a sheet is conveyed from a processing tray to a stacking tray, a bar-like pushing member is moved in a direction of the stacking tray in synchronization with an ejector. Consequently, simultaneously with the movement of the sheet by the ejector, a lower surface of a leading end of the sheet is pushed to relax and reduce a contact force between the lower surface of the leading end of the sheet and the stacking tray (or an upper surface of a sheet already stacked on the stacking tray). As a result, static friction at the leading end of the sheet is changed to dynamic friction and the entire sheet is conveyed to the stacking tray without bending.

  • Patent number: 6695304
    Abstract: Envelope alignment of a vertical stack of envelopes in an envelope hopper is maintained by mechanically vibrating a preselected part of the hopper. In a first embodiment, the vibration is caused by a reciprocating shuttle having a wedge-shaped member attached to it. The reciprocating shuttle and wedge member are positioned at the bottom of the hopper so that the shuttle and wedge-shaped member support all of the envelopes. The reciprocation of the shuttle and hence the reciprocation of the wedge-shaped member continually jostles the envelopes. The wedge-shaped member ejects the lowermost envelope in the hopper when the reciprocating shuttle is displaced from a retracted position to an extended position. A motor is used to cause continuous reciprocation of the shuttle. In alternative embodiments, different parts of the envelope hopper are vibrated by any suitable vibration-causing member.

  • Patent number: 6557848
    Abstract: A paper-stopping mechanism applied in an automatic document feeder (ADF). The paper-stopping mechanism includes a shaft, a stepping motor for carrying the shaft to rotate, a cam structure having a first protruding portion and a second protruding portion and carried by the shaft to rotate the first protruding portion and the second protruding portion thereof, a paper-stopping arm having a bearing point, wherein the bearing point is moved against by the first protruding portion to move the paper-stopping arm upward, and an elastic buckling device for buckling the paper-stopping arm when the paper-stopping arm is moving upward to stay at a paper-feeding position, and for shifting when the second protruding portion of the cam structure is rotated against the elastic buckling device for removing the paper-stopping arm from the elastic buckling device to return to a paper-stopping position.

  • Patent number: 6471424
    Abstract: A printer is provided, which comprises a printer body 20 including a paper sheet feeding unit for setting paper sheets therein for printing and a paper sheet discharging unit, and a printer controller 10 of the printer body 20. When setting again paper sheets after printing on one surface in the paper sheet feeding unit for printing on the other surface, the printer body 20 is adapted to print, under control of an instruction from the printer controller 10, a first symbol indicating that the paper sheets should be set in the paper sheet feeding unit with the upper, lower, left or right part of the printed surface directed in the paper sheet feed-out direction and also with the printed surface up or down.

  • Patent number: 6371474
    Abstract: When it is detected that a first containing section contains or is being supplemented with used paper sheets, a CPU feeds the used paper sheets one by one to a table incorporated in a housing tray in a second containing section, via a conveyance path. When the housing tray is filled with used paper sheets, the CPU stops feeding and conveyance of used paper sheets from the first containing section to the second containing section, and confirms whether a main body is operating or is in a late-night standby state. If it is confirmed that the main body is operating or is in the late-night standby state, the table in the second containing section is moved into the third containing section, thereby shifting the used paper sheet on the table to the third containing section. The used paper sheets placed in the third containing section are fed to the main body one by one when necessary.

  • Patent number: 6209861
    Abstract: A sheet transport device is provided with a sheet inverting mechanism for retracting a sheet transported along a main transport route into a switchback route to invert the sheet transport direction and returning the sheet into the main transport route to turn the side of the sheet. The sheet transport device has a pair of sheet guides adapted in contact with respective opposite ends of the sheet set on a sheet setting portion to prevent a skew transport of the sheet. The sheet temporarily brought onto the sheet setting portion during a switchback operation from the switchback route is guided between of the sheet guides on the sheet setting portion. During the temporal appearance on the sheet setting portion, the opposite ends of the sheet are aligned by the respective sheet guides. Thereby, securely prevented is an occurrence of a skew transport state of the sheet during the switchback operation.

  • Patent number: 6206367
    Abstract: An automatic sheet feeder for an ink jet printer is disclosed. The automatic sheet feeder includes a sheet support fixed to a frame. A shaft is rotatably secured to an upper portion of the sheet support, and rotates in a specified direction by a driving force from a driver. A sheet width adjusting guide is movably mounted on one side of the shaft such that a front end is movable along the shaft and a rear end is slidable keeping in contact with the sheet support. At least one feeding roller assembly is rotatably mounted on another side of the shaft, and includes a feeding roller for feeding a sheet by a rotation force of the shaft. The shaft rotates in such a direction that the feeding roller contacts the sheet, and the feeding roller rotates in an opposite direction of the shaft.
