A placement station for placing flat items has multiple transport elements extending through a related opening in a placement deck of the placement station. All transport elements are driven by a single drive motor via toothed belt discs and toothed belts. At least one trigger sensor is arranged in the placement station on the exit side of the mail-item flow. The drive motor and the trigger sensor are electrically connected with means for controlling the transport speed of the flat items. Each transport element is carried by a transport module. The placement station has multiple transport modules, each extending with a transport element mounted on its head side through a related opening in a placement deck of the placement station. The transport modules are lowerable below the placement deck in a direction contrary to a spring force. The direction of traction can be changed by turning at least one transport module before or during operation of the placement station. Each transport element has a barrel-shaped body with an equator, wherein different friction values of said body of the transport element are provided on both sides of the equator. The transport modules are directionally positioned such that the half of the body of the transport element with the higher friction value is closest to the alignment wall.

There is provided a feed apparatus including a support unit having a support surface, a feed roller, a first arm to support the feed roller, a recess portion on the support surface, a second arm swingable, with a side of the one end as a swing shaft, between a first position at which the other end of the second arm is in the recess portion and a second position at which the other end is outside the recess portion; and a biasing member. In a case that the second arm is the first position, a guide surface of the second arm is positioned on an upstream side of the feed roller in the feed direction and in a case that the second arm is the second position, the other end of the second arm is positioned on a downstream side of the feed roller in the feed direction.

An image forming apparatus includes a print medium tray in which a print medium is loaded and a pickup roller which is configured to pick up the loaded print medium from the print medium tray. The pickup roller includes at least one first pickup block and at least one second pickup block configured to alternately come into contact with an upper portion of the loaded print medium. Using such a configuration, the pickup performance of the image forming apparatus may be improved.

A paper feeding unit of an image forming apparatus according to an exemplary embodiment is provided with a base portion, a guide, a protruding portion, and a roller. The base portion is capable of having the sheet placed thereon. The guide erects with respect to the base portion. The guide regulates a position of the sheet in a width direction which intersects with a transporting direction of the sheet. The protruding portion is provided on the guide. The protruding portion faces an end portion of the sheet in the width direction from a side opposite to the base portion. The roller is provided on the protruding portion. The roller is provided with a circumferential surface facing the end portion of the sheet. The roller is rotatable in the transporting direction of the medium.

A sheet feeding device, which is included in an image forming apparatus, includes a sheet container to accommodate a recording medium, a sheet feeding body to press a surface of the recording medium in the sheet container and feed the recording medium in a sheet conveying direction, a pair of sheet position regulators to regulate a position of the recording medium in a sheet width direction perpendicular to the sheet conveying direction, and a load applier to contact the surface of the recording medium and apply a load to the recording medium at the surface. The recording medium is brought to move toward one of the pair of sheet position regulators while the recording medium is being fed. A lower face position in a standby state of the sheet feeding body is lower than a lower face position in a standby state of the load applier.

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).

A paper feeding device of an image forming device includes a flotation air blowing unit and a separation air blowing unit. The flotation air blowing unit floats stacked uppermost paper through air blowing. The separation air blowing unit blows an end of other paper floated together with the floated uppermost paper to separate the other paper from the uppermost paper, the end being on the downstream side in the paper feeding direction. The flotation air blowing unit floats an end of the stacked uppermost paper, the end being on the downstream side in the paper feeding direction. The paper feeding device includes a resistance force applying mechanism which applies resistance force that gives a load against movement along the paper feeding direction to an end of stacked upper paper, the end being on the upstream side in the paper feeding direction.
