SHEET FEEDING DEVICE INCLUDING A PLURALITY OF SEPARATION PIECES MOVABLE TO SEPARATE UPPERMOST SHEET FROM STACK OF SHEETS
A sheet feeding device includes: an accommodating unit having a placement surface on which the stack of sheets is mounted; an inclined member having an inclined surface inclined relative to the placement surface to extend in an inclined direction and a back surface opposite the inclined surface; a sheet pick-up unit for feeding an uppermost sheet in the stack of sheets toward the inclined member; and a sheet separating member provided on the inclined surface. The sheet separating member includes a plurality of separation pieces and a support portion those made of resin. The support portion supports the separation pieces at positions closer to the back surface than to the inclined surface so that the separation pieces are movable away from the placement surface in the inclined direction and toward the back surface in a normal direction of the inclined surface independently from one another.
Adjustable compliance of separation strips in a media dam
In a copier, printer, or similar device, paper is loaded in large quantities. To separate a top sheet of a stack of sheets from the next adjacent sheet, a dam is used, which is an element having an inclined surface in the path of the top sheet. This invention addresses devices with variably compliant separation strips, preferably a thermoplastic polyurethane elastomer such as Pellethane®, that are part of the dam, so that the leading edge of a media sheet will strike the inclined surface of the separation strip. By adjusting the compliance of the separation strip, different weights of media may be accommodated while minimizing the multi-feeds that may cause jamming of the device.

DETERMINATION OF PRINT MEDIA AMOUNT
An example apparatus includes a processor and a memory in which is stored machine-readable instructions that are executable by the processor. The instructions cause the processor to determine a first operating torque response of a motor during a first operation of the apparatus, determine a second operating torque response of the motor during a second operation of the apparatus, the second operation being different from the first process, and determine an amount of media present in a media bin based on the first operating torque response and the second operating torque response.
SHEET FEEDER WITH SHEET FORMING MEANS
Sheet feeding device (1) comprising an elevator (2) for a stack of sheets, and an air supply system (3) configured to supply and direct one of more air streams towards an upper region (4) of the sheet feeding device (1) for floating a plurality of upper sheets of the stack of sheets, wherein the elevator (2) comprises a vertically movable support (5) for supporting the stack of sheets from below, wherein the sheet feeding device (1) comprises a first side support member (6) and a second side support member (7) configured to sideways support respective opposite sides of the stack of sheets, wherein the sheet feeding device (1) further comprises a vacuum belt feeder (8) provided above the elevator (2) and configured to grab and feed an uppermost sheet of the floated sheets away from the floated sheets, and wherein an upper portion of each side support member (6, 7) is provided with at least one respective cam (9) comprising a respective guide surface extending obliquely upwards-inwards from the respective side support member (6, 7).
Spring kicker element
A spring kicker element for a kicker unit within a print device is described. In one example, the spring kicker element is fitted onto the kicker unit. The spring kicker element comprises a planar extension extending radially from its base portion, such that when fitted, the planar extension extends away from the kicker unit.

IMAGE PROCESSING APPARATUS
An image processing apparatus includes: a support surface configured to support a sheet, a sheet feeding roller configured to feed the sheet in a conveying direction, a separation member for separating the sheet one by one and positioned downstream of the sheet feeding roller in the conveying direction, and a regulating member displaceable between a first position where the regulating member abuts against a distal end of the sheet supported by the support surface to regulate passage of the sheet in the conveying direction between the sheet feeding roller and the separation member and a second position that is farther from a conveyance path than the first position and that allows passage of the sheet in the conveying direction. The regulating member has a wall surface that abuts against the distal end of the sheet and includes at least one protrusion on the wall surface.

MEDIUM-TRANSPORTING DEVICE AND IMAGE READING APPARATUS
A medium-transporting device includes: a medium-mounting section on which a medium is mounted; a feeding unit that includes a feeding roller and that is configured to be displaced between a contact posture and a separation posture; a first restricting member that is provided downstream of the feeding roller in the transport direction and that is configured to switch between a restriction posture in which the first restricting member restricts movement of the medium and a retreat posture in which the first restricting member permits the movement of the medium; a first motor configured to generate power for rotating the feeding roller; and a second motor configured to generate power for switching a posture of the first restricting member, in which an operation of rotating the feeding roller and an operation of switching the first restricting member from the restriction posture to the retreat posture are performed in parallel.
