A medium feeding device includes a medium placement portion on which a bunch of media is placed, a feed roller that feeds a lowermost medium of the bunch of media placed on the medium placement portion, a separation roller that is provided at a position facing the feed roller and separates a medium from the bunch of media, and a plurality of restricting portions that are provided on an upstream side of a nip position between the separation roller and the feed roller at an interval in a medium width direction which is a direction intersecting a medium feeding direction and come into contact with leading ends of upper media of the bunch of media excluding at least the lowermost medium such that the leading ends are restricted from coming into contact with the separation roller regardless of whether the separation roller is deformed or not.

A paper pickup mechanism includes a mechanical frame, a pickup roller module, a feeding roller module, a driving device, a separation roller module and an energy storage element. The mechanical frame has a platform. The pickup roller module is pivoted to and connected to the mechanical frame. The feeding roller module is pivoted to and connected to the mechanical frame. The driving device is mounted to the mechanical frame. The separation roller module is pivoted to and connected to the mechanical frame. The energy storage element is mounted between the mechanical frame and the separation roller module. When the separation roller module rotates together with the feeding roller module in a forward direction, the energy storage element accumulates energies. When more than one piece of paper is fed into the paper pickup mechanism, the energy storage element releases the energies.

An individualization station has a supply deck for supplying flat goods to a goods processing apparatus following in the transport path in the transport direction x of a Cartesian coordinate system, with openings in the supply deck for a drum in an individualization region, and with individualization assembly as well as with a contact pressure box. The contact pressure box is movable in the z-direction, and has a linkage that is pivotable at a downstream end. An individualization assembly carrier forms an L-shape at an upstream end of the linkage that is pivotable in the contact pressure box. A stop side of the undeflected individualization assembly carrier is aligned parallel to the y/z-plane and extends counter to a y-direction. The individualization assembly carrier can be deflected above the supply deck at a variable distance corresponding to the thickness of the flat good to be individualized, and is adjustable in the y-direction and counter thereto by an adjustment assembly.

A medium feed device includes a feed roller provided to a device body and configured to feed paper, a separator roller provided at a position on the device body facing the feed roller and configured to separate the paper, and a medium support section configured to support the medium in an inclined state upstream of the feed roller. The medium support section is configured with a variable contact angle between the paper supported by the medium support section and the separator roller.

A paper sheet feeding unit includes: a plurality of feed rollers; a plurality of gate rollers respectively disposed opposite to the plurality of feed rollers in a one-to-one relationship; a biasing member that biases the plurality of gate rollers individually in a direction of the plurality of feed rollers; and a supporting member that supports the plurality of gate rollers and the biasing member.

A feeding unit includes: a retard roller; a holder section; a protruding section; an accommodating section; a pressing section; a first restricting section; and a second restricting section. The holder section rotatably holds the retard roller. The protruding section serves as a rocking fulcrum of the holder section. The accommodating section accommodates the holder section. The pressing section presses the holder section. The first restricting section restricts movement of the holder section in a retreating direction. The second restricting section restricts movement of the holder section in a direction opposite to the retreating direction. The pressing section is arranged so as to deviate in a Y direction with respect to a virtual line passing through a middle point of the protruding section and a middle point of the first restricting section. The holder section comes into contact with the first restricting section and the second restricting section.

A paper pickup mechanism includes a mechanical frame, a pickup roller module, a feeding roller module, a driving device, a separation roller module and an energy storage element. The mechanical frame has a platform. The pickup roller module is pivoted to and connected to the mechanical frame. The feeding roller module is pivoted to and connected to the mechanical frame. The driving device is mounted to the mechanical frame. The separation roller module is pivoted to and connected to the mechanical frame. The energy storage element is mounted between the mechanical frame and the separation roller module. When the separation roller module rotates together with the feeding roller module in a forward direction, the energy storage element accumulates energies. When more than one piece of paper is fed into the paper pickup mechanism, the energy storage element releases the energies.

An apparatus and a corresponding method for singling value documents includes: an input device which is devised for receiving a stack of value documents, a transport device which is devised for drawing a value document from a stack of value documents located in the input device, and a transport element, which is devised to influence the drawing of the value document from the stack of value documents. At least one sensor is provided which is devised to capture a size of the stack located in the input device, in particular a height of the stack and/or a fill level of the input device, and a density of the stack. A control device is devised to control the transport device and/or the transport element based on the captured size of the stack and/or the captured density of the stack.

A medium feeding device includes a medium placement portion on which a bunch of media is placed, a feed roller that feeds a lowermost medium of the bunch of media placed on the medium placement portion, a separation roller that is provided at a position facing the feed roller and separates a medium from the bunch of media, and a plurality of restricting portions that are provided on an upstream side of a nip position between the separation roller and the feed roller at an interval in a medium width direction which is a direction intersecting a medium feeding direction and come into contact with leading ends of upper media of the bunch of media excluding at least the lowermost medium such that the leading ends are restricted from coming into contact with the separation roller regardless of whether the separation roller is deformed or not.

A paper feeding mechanism includes a lower frame, an upper frame, a separation roller, a pickup roller, a paper feeding channel and at least one blocking element, the lower frame has a groove, the separation roller is mounted to the upper frame, the pickup roller is mounted to the lower frame and placed in the groove, a paper feeding channel is formed between the separation roller and the pickup roller, or between the separation roller and the lower frame, the blocking element is pivoted on the upper frame and placed beside the separation roller, the blocking element has a stopping part, the stopping part contacts the lower frame.
