When a sheet ejector ejects an unsuitable sheet from a transport path in a printing system, additional sheets downstream of said unsuitable sheet are generally discharged to preserve the image order as prescribed by the print instructions. This results in large amounts of waste material (sheets and ink). The amount of waste may be reduced by providing a controller which, when receiving print instructions concerning a first and a second set of images, schedules the images of the first and second sets into an alternating image sequence defining the print order. Sheets printed with images from the first set are designated to a first output holder while sheets printed with images from the second set are transported to the second output holder. When a sheet for the second image set is rejected, the first image set need not be discharged, resulting in a reduced amount of waste material.

A sheet medium flattening device includes a mounting frame configured to mount and support following components; an annular passage, including an annular inner passage plate and an annular outer passage plate, a heating module arranged in a hollow inner cavity of the inner passage plate to supply heat for the inner passage plate; at least one pinch roller arranged at an outer side of the annular guiding plate and realizing clamping with the inner passage plate through a hole slot arranged in the annular guiding plate; a reversing mechanism configured to selectively convey banknotes between the conveying passage and the annular passage of the flattening device; a driving device configured to drive the inner passage plate to rotate; and a control system configured to control a temperature of the heating module and control a selectively switchover of the reversing mechanism.

Provided is a sheet processing device able to suppress consumption of sheets. The sheet processing device has a supply device that supplies sheets; an image acquisition device that acquires an image of a sheet supplied from the supply device; a first decision device that determines whether or not the sheet can be reused based on the image of the sheet acquired by the image acquisition device; and an inverter configured to discharge the sheet without reversing the first side and second side of the sheet when the first decision device determines that the first side of the sheet can be reused, and reverses the first side and second side of the sheet and then discharges the sheet when the first decision device determines that the second side of the sheet can be reused.

A paper feed roll includes a shaft body and an elastic body layer formed on the outer circumferential surface of the shaft body. The outer diameter of the elastic body layer is 10-50 mm, the outer circumferential surface of the elastic body layer is provided with, in the circumferential direction, 1-8 grooves extending in the axial direction, the grooves have a constant groove width in the depth direction or have a groove width that gradually decreases in the depth direction, the groove width of the grooves is 0.2-1.0 mm, and the groove depth of the grooves is 0.2-1.0 mm.

The invention relates to a device for unwinding a coil of a metal strip including a bogie translatable back and forth along a guiding system; a blocking system which is arranged on said bogie and which contains a first and a second shaped element, wherein the first shaped element is a roller, preferably an idle roller; an actuating system for modifying the distance between the two shaped elements, for defining an intercepting position and a gripping position of the strip; and an element for detaching the strip from the coil provided on the first shaped element. A relative method of unwinding and inspecting a metal strip is also described, in particular used to check the state of wear of rolling cylinders used for producing the inspected strip.

A banknote processing apparatus capable of properly storing and dispensing a banknote is provided. The banknote processing apparatus includes: a transport unit that transports a banknote; a long-edge orientation storage unit that receives and stores, in a first orientation, the banknote transported by the transport unit, the first orientation being an orientation in which a short edge of the banknote is a leading edge thereof; a short-edge orientation storage unit that receives and stores, in a second orientation, the banknote transported by the transport unit, the second orientation being an orientation in which a long edge of the banknote is a leading edge thereof; and a control unit that selects, by controlling the transport unit, a storage destination for the banknote transported by the transport unit, from among any of the long-edge orientation storage unit and the short-edge orientation storage unit.

A printing apparatus includes a transport unit which includes a transport roller pair which transports a medium in a transport direction, a printing unit which prints onto the medium, a winding unit which winds the printed medium, and a tension application unit which applies a tension to the medium at a position between the transport roller pair and the winding unit. The tension application unit includes a pair of arms which are capable of rotating. A tension bar is supported on one end of the arms and comes into contact with the medium. The bar is rotated from an upper limit position to a lower limit position by transportation of the transport unit being performed two or more times.
