A sheet-conveying device contains a first linear sheet-conveying path on which the sheet is conveyed, a curved sheet-conveying path connecting the first linear sheet-conveying path and a second linear sheet-conveying path connecting the curved sheet-conveying path. A curved conveying guide is provided at only an outside of a curved sheet-conveying route. Conveying guide rollers are provided at an upstream side of the curved conveying guide. The conveying guide rollers contain a driving roller which is arranged at outside of the curved sheet-conveying path and a driven roller which is arranged at inside of the curved sheet-conveying path. The driven roller has a diameter more than that of the driving roller. The driven roller also has hardness less than that of the driving roller.

A thickness detector includes a rotator having different shape marks, disposed at different positions in a rotation direction; an opposing member disposed opposite the rotator; a detector to detect and output a displacement amount of the rotator or the opposing member in a sheet thickness direction; and a controller. The controller is configured to acquire first output values for one rotation from the detector, in a state without sheet; determine, based on a value output from the detector, whether one of the plurality of marks is detected in a state with the sheet held; acquire a predetermined number of second output values after one of the marks is detected; extract, from the first output values, values corresponding to the second output values, based on the value corresponding to the detected mark; and calculate a sheet thickness based on the second output values and the extracted first output values.

A tension-inducing shaft system includes a shaft, two shaft caps, and a biasing mechanism. A bore extends through the shaft between two ends of the shaft. The shaft caps are positioned on the two ends of the shaft. Each shaft cap includes a collar having a size that is larger than the bore, a keyed end, and an anchor. The biasing mechanism is arranged inside the bore and is coupled to the anchors of the shaft caps so that the biasing mechanism exerts inward forces on the shaft cap. The keyed ends of the shaft caps can be coupled to a housing so that the shaft caps do not rotate with respect to the housing. The shaft is configured to rotate with respect to the shaft caps such that, when the keyed ends are coupled to the housing, the shaft is capable of rotating with respect to the housing.

The present disclosure is, in one aspect, directed to a sheet material dispenser assembly including a dispenser housing with at least one support and a discharge. The dispense assembly has a supply sheet material at least partially supported by the at least one support, and at least one driving roller driven to direct sheet material from the supply of sheet material to the discharge. In addition, the dispenser assembly includes a plurality of pressing rollers at least partially engaging the sheet material against the at least one driving roller as the at least one driving roller is driven to direct the sheet material towards the discharge, which pressing rollers are held in a substantially tensioned arrangement to facilitate a consistent drawing or pulling of the sheet material.

An automatic electronic dispenser for dispensing a roll of paper product that avoids refeeding of paper by retarding breaking on the high side of the roll. A dispenser module drives paper from the roll through a discharge chute at the bottom of the module. The dispenser module utilizes two floating pressing rollers and a belt drive that provides quiet and consistent operation by pressing of the two pressing rollers onto a main roll. The dispenser module including a main bar module which holds the roll and which is received on paper holder arms.

A recording medium conveyor includable to an image forming apparatus includes a driving source, a first rotary unit, and a second rotary unit. The first rotary unit includes a driving gear, a driving shaft rotating with the driving gear, and multiple driving rotary bodies disposed on the driving shaft. The second rotary unit disposed facing the first rotary unit includes a driven gear meshed with the driving gear, a driven shaft, multiple driven rotary bodies disposed on the driven shaft, and multiple stiffening rotary bodies disposed between two of the multiple driven rotary bodies and having a diameter greater than an outer diameter of the multiple driven rotary bodies. A gear ratio between the driving gear and the driven gear is adjusted such that a peripheral speed of the multiple driving rotary bodies is equal to a peripheral speed of the multiple stiffening rotary bodies.

A sheet-type medium separating apparatus applicable in a self-service financial device for reliable sheet-by-sheet separation of an entire stack of banknotes. The apparatus includes a pickup roller component; a reversal roller component; and a separation roller component, where the reversal roller component includes a reversal roller, the reversal roller is fitted onto a reversal roller shaft via a one-way bearing, the reversal roller is provided with an inner sleeve cylinder fixed with the one-way bearing and a reversal roller sleeve sleeved onto the inner sleeve cylinder and capable of moving axially and flexibly. The separating apparatus allows for automatic adjustment of the meshing clearance between the reversal roller and the separation roller on the basis of the thickness of sheet-type media to be separated, thus effectively solving the problem of the sheet-type media being jammed or torn.
