A sheet feeder device includes: a sheet feed tray configured to store a sheet stack formed with a plurality of paper sheets; an elastic member capable of expanding and contracting; a contact mechanism configured to bring the elastic member into contact with an edge of the sheet stack; an expansion mechanism configured to expand the elastic member in a direction of stacking of the paper sheets; and a control unit configured to cause the expansion mechanism to expand the elastic member while the elastic member is kept in contact with the edge of the sheet stack by the contact mechanism.

An object of the invention is to provide a sheet materials separation-aiding apparatus capable of creating a gap between a specific sheet material and a sheet material coming into contact with the lower surface thereof even when the location precision of a stack of laminated sheet materials is low in the height direction of the stack of laminated sheet materials and in the direction orthogonal to the height direction.

A medium transport apparatus includes: a frame; a table including a placement surface on which a medium is placed, a first end portion, and a second end portion, the table extending from the first end portion to the second end portion and being rotatable about a first shaft portion parallel to the placement surface; a first rotor arranged adjacent to the first end portion of the table; a second rotor arranged adjacent to the second end portion of the table; a belt that is stretched by the first rotor and the second rotor, and is configured to rotate circularly and to transport the medium in a first direction from the first end portion toward the second end portion; and a biasing part that links the frame and an attachment part provided between the second end portion and the first end portion of the table, and that biases the table.

A feeding device for a digital processing machine includes a paper passage, a sheet-feeding roller, a friction device, and a slide. The sheet-feeding roller is disposed in the paper passage, and the friction device is disposed opposite to the sheet-feeding roller. The sheet-feeding roller separates a sheet with the friction device. The slide is disposed at a left side and a right side of the sheet-feeding roller. The slide is lowered from a first position to a second position when the sheet-feeding roller rotates, such that the sheet contacts the sheet-feeding roller.

A medium conveyance device includes: a first conveyance unit that applies a first conveyance force in a conveyance direction to a lowest medium among media on a medium stacker; a second conveyance unit disposed downstream in the conveyance direction of the first conveyance unit and that applies a second conveyance force in the conveyance direction to the medium being conveyed in the conveyance direction; a detector that detects that a rear end of the lowest medium receiving the first conveyance force passes through the first conveyance unit; and a controller that controls the first and second conveyance units. Upon determining that the rear end of the lowest medium receiving the first conveyance force passes through the first conveyance unit, the controller switches the first conveyance unit from a conveyance state of applying the first conveyance force to a non-conveyance state of not applying the first conveyance force.

A feeder device for feeding mailpieces to a postal sorting conveyor has an unstacker head designed to put the mailpieces in series and on edge on the sorting conveyor, an unstacker plate designed to unstack the mailpieces one-by-one towards the unstacker head, and a mailpiece feed conveyor designed to convey the mailpieces in a stack and on edge against the unstacker plate. The unstacker plate has a stationary portion that extends from the unstacker head, and a moving portion that extends the stationary portion, said moving portion being mounted to pivot from the stationary portion between a first position in which the stationary portion and the moving portion are aligned with each other, and a second position in which the stationary portion and the moving portion are angularly offset relative to each other.

A tiltenator of a media separator module (integrated within a valuable media depository) adaptively controls pressure maintained against a bunch of media as individual items from the bunch are fed through the media separator module.

A document separator for use in a document processing machine. The document separator has a flexible loop of material adjacent to a document transport mechanism so that it holds one or more documents back from being transported along a transport path while allowing a single document to be moved forward.

A system includes a sheet holder configured to hold a sheet of blanks, the sheet of blanks including a first blank and a second blank attached to the first blank. A conveyor mechanism is configured to transport the sheet of blanks from the sheet holder to a separator mechanism. The separator mechanism is configured to apply a pulling force to the first blank. A resistance component is configured to apply a resistance force to the second blank to resist the pulling force. The pulling force and the resistance force are configured to separate the first blank from the second blank.

A sheet feeder device includes: a sheet feed tray configured to store a sheet stack formed with a plurality of paper sheets; an elastic member capable of expanding and contracting; a contact mechanism configured to bring the elastic member into contact with an edge of the sheet stack; an expansion mechanism configured to expand the elastic member in a direction of stacking of the paper sheets; and a control unit configured to cause the expansion mechanism to expand the elastic member while the elastic member is kept in contact with the edge of the sheet stack by the contact mechanism.
