A banknote separating device is applicable for a financial self-service equipment, includes a banknote separating wheel set and a reverse wheel set for cooperating with the banknote separating wheel set, and the reverse wheel set includes a reverse-wheel-set rotating shaft, a reverse wheel fixing frame, and a reverse wheel assembly. One end of the reverse wheel assembly sequentially passes through an E-shaped snap ring, a flanged bearing, a one-way bearing stop ring and a one-way bearing to be mounted to the reverse wheel fixing frame, and the one-way bearing and the reverse wheel fixing frame are coupled by the one-way bearing stop ring to form a stationary rigid body, and the one-way bearing stop ring is in contact with only an outer ring of the flanged bearing.

In the separation roller, an entire area of a circumferential surface of the separation roller facing the sending roller is exposed to come in direct contact with the banknote, moving from the storage unit, on the storage unit side with respect to a contact portion which is in contact with the sending roller, both end portions in an axial direction of the separation roller are formed of a material having a friction coefficient smaller than that of a central portion thereof, and the diameter of the both end portions is the same as the diameter of the central portion.

There is provided a feed apparatus including a support unit, a feed roller, a swingable arm to support the feed roller, a guide unit, a movable member movable to a retracted position and a protruding position at which the movable member can abut against the sheet supported by the support unit, a driving source, driving transmission units; and a contact-separating mechanism to move the feed roller to a separated position and an abutment position at which the feed roller abuts against the sheet supported by the support unit. In a state in which the movable member is the protruding position and the feed roller is the separated position, a time required to start feeding of the sheet by the feed roller moved from the separated position to the abutment position is longer than a time required to shift the movable member from the protruding position to the retracted position.

An image forming apparatus includes a sheet container accommodating a recording medium therein, a sheet separating feeder including a sheet feeding body and a sheet separating body, an image forming part, and a bend applier. The sheet feeding body feeds the recording medium along with a surface movement thereof while the recording medium contacting the surface thereof. The sheet separating body forms a sheet separation nip region with the sheet feeding body and sandwiches the recording medium in the sheet separation nip region. The sheet separating feeder separates and feeds the recording medium contacting the sheet feeding body. The image forming part forms an image on the recording medium. The bend applier having a leading end of an elastic material contacts and bends the recording medium before the sheet separation nip region and generates a wrinkle extending on the recording medium in a sheet conveying direction.

A feeding device includes a roller configured to feed an uppermost sheet of a plurality of sheets stacked in a stacking unit, and an inclined separator located downstream of the roller in a feed direction and configured to separate one sheet from another sheet. The inclined separator includes a first separator and a second separator that are arranged along the feed direction. Resistance imparted to each sheet by the first separator is greater than resistance imparted to each sheet by the second separator.

A mail processing system utilizes a conveyor to shingle or de-shingle mailpieces as they move through the processing system and utilizes belts to move the mailpieces. A first shingling conveyor moves a first mailpiece to overlap with a second mailpiece to create shingled mailpieces. A second shingling conveyor moves a first mailpiece away from a second mailpiece to de-shingle them to create singulated mailpieces. A camera takes images of the mailpieces in the conveyor and image analysis software is used to determine dimensional aspects of the mailpieces that are used to control the belt speeds to move mailpieces with respect to each other. A mail processing system may include a mail processing station that scans addresses, applies postage and/or weighs the mailpieces. Mail may be de-shingled prior to being weighed and then re-shingled for subsequent processing, or mail may be shingled prior to passing through a scale if weighing is not necessary.

A paper feed roller including an elastic layer composed of thermosetting polyurethane containing a plasticizer, wherein an amount of the plasticizer is within a range of 10 to 50 pts. mass based on 100 pts. mass of the thermosetting polyurethane, and a surface residual charge on the elastic layer is within a range of 90 to 170 V. The surface residual charge is a value determined by single-point measurement of a surface potential of the elastic layer. The measurement includes rotating the paper feed roller in a circumferential direction, electrifying the surface of the elastic layer with a corotron while rotating the paper feed roller, and measuring the surface potential at a center point on the paper feed roller in a roller axis direction in a position where the paper feed roller is rotated by 90 degrees from a position where the surface of the elastic layer is electrified.
