    摘要： Presented herein is a sheet turning unit (1) comprising a first sheet conveyor device (2a) for transporting a sheet at least along a first transport path (B1) in a first plane (E1), and comprising a second sheet conveyor device (2b) for transporting the sheet along a second transport path (B2), said second transport path extending at an angle of 90° with respect to the first transport path (B1) and, in sum, describing a curve of 180°, whereby the starting point of said curve is located in the first plane (E1) and the end point of said curve is located in a second plane (E2) that is different from the first plane, and comprising a third sheet conveyor device (2c) for transporting the sheet along at least a third transport path (B3). As a result of this, the leading edge of the sheet remains in front even after the turning operation, and a precisely functioning and reliable sheet turning unit is being provided. Furthermore, advantageous embodiments of the first and third sheet conveyor devices are described, said devices enabling the transport of a sheet in two directions. The advantageous embodiments of the first and third sheet conveyor devices are compact and simple in design and can be controlled easily. The advantageous embodiments of the first and third sheet conveyor devices comprise a sheet transport body that, by means of a rotating mechanism arranged in the sheet transport body, can be rotated about a first rotational axis and a second rotational axis, said axes extending through one point of intersection and being perpendicular to one another.

    摘要： A sheet storage device includes a first reel, a second reel, a third reel, a shaft, a drum, a first differential mechanism and a second differential mechanism. Tips first, second and third tapes respectively unwound from the first reel, the second reel, and the third reel are fixed to the drum, and the drum winds up sheets together with the first, second and third tapes. The first differential mechanism distributes torque input from a torque source to a first path and a second path. The second differential mechanism is provided in the second path and distributes the torque that has been distributed by the first differential mechanism to a third path and a fourth path. The first reel is located in the first path, the second reel is located in the third path, and the third reel is located in the fourth path.

    摘要： A sheet registration system, especially for printers, with a lower cost and lower mass-movement system for both sheet deskewing and transverse registration repositioning of the sheets in the same integral system, especially for higher speed printing. Only one main drive motor can drive both of the two spaced apart sheet feeding nips, together with a lower power, lower mass, deskewing differential drive system for providing the relative differential angular movement of the two spaced sheet feeding nips to achieve the desired amount of sheet deskewing movement, without interrupting the forward feeding movement of the sheet. Also disclosed are extensive further reductions in the component mass of the lateral translation movement for lateral sheet registration.

    摘要： A medium feeding device includes a feeding roller that conveys a medium in a conveying direction, and a brake roller that includes rollers that are arranged to be rotatable around one shaft and cause a conveyance load to act on the medium that has entered between the feeding roller and the rollers. The rollers are arranged to press the feeding roller with a predetermined pressure. The medium feeding device further includes a rotational difference generating unit that generates a rotational difference between the rollers so that the conveyance load acting on the medium by the rollers becomes even.

    摘要： An apparatus includes a differential to receive a primary driving force, and provide a first driving force and a second driving force. A first pick wheel is to transfer the first driving force to a sheet. A second pick wheel is to transfer the second driving force to the sheet. The differential is to balance the first driving force and the second driving force to reduce skew in the sheet and feed the sheet along a feed path of a printer. The first pick wheel and the second pick wheel are aligned perpendicular to the feed path at an offset from the differential.
