A magnetic-ink reading device includes a housing and a conveyor in the housing. A medium inlet and outlet port for inserting and pulling out a medium printed using magnetic ink are in the housing. The conveyor conveys the medium along a conveying path. The magnetic-ink reading device includes a magnetizing mechanism configured to magnetize the magnetic ink of the medium on the conveying path and a magnetism detection head disposed near the magnetizing mechanism and configured to read magnetism of the magnetized magnetic ink. The magnetic-ink reading device includes a reversing mechanism provided on the medium inlet and outlet port side of the conveying path and configured to reverse front and rear surfaces of the medium on a reversing path on an inside. The reversing mechanism includes a retraction path for temporarily retracting the medium when the magnetism of the medium is read by the magnetism detection head.

A first unit includes a receiving portion that receives a medium to be processed, a drying unit that processes the medium received from the receiving portion, and an end stitching unit that processes the medium received from the receiving portion or the medium processed by the drying unit. The processing performed by the drying unit is processing of drying the medium, the drying unit is located vertically below the end stitching unit, and the drying unit and the end stitching unit have a portion overlapping when viewed in a vertical direction.

A printing apparatus, including a sheet conveyer unit with a first roller unit, a printer unit, and a controller, is provided. The controller executes a first-face printing process, wherein an image is printed on a first face of a sheet; a switchback process, wherein the sheet after the first-face printing process is conveyed in a reverse direction by the first roller unit; a second-face printing process, wherein the image is printed on a second face of the sheet; a first ink amount determining process to determine whether an ink amount discharged in the first-face printing process at an end area of the sheet is one of greater than and equal to a first threshold amount; and a switchback setting process, wherein, if the ink amount is smaller than the first threshold amount, a rotation speed of the first roller unit is set at a higher rotation speed.

A system for processing printed products includes a transfer station which is provided with an infeeding location for infeeding printed products to the transfer station from a delivery station. The transfer station further comprises a number of connecting locations and a removal location. To each of the connecting locations is connected a processing station. An output station is connected to the removal location. The transfer station is further provided with a transporting device for moving the printed products within the transfer device between the infeeding location, the various connecting locations and the removal location. The printed product infed to the transfer station at the infeeding location is transported in any sequence from the transfer station to one of the processing stations. After completion of the processing operation in a particular processing station, the printed product is moved back to the transfer station. The finished printed products are removed from the transfer station at the removal location.

A sheet folding apparatus includes a conveyor, a first folding roller, a second folding roller, a third folding roller, a guide, a motor, and a driving force transmission mechanism. The motor causes the second folding roller to perform either forward rotation in which the second folding roller rotates to convey a sheet on a main conveying path in a conveying direction and to convey the sheet on a reflux conveying path from a joining position toward a branching position or backward rotation in a direction opposite to the forward rotation. The driving force transmission mechanism rotates the guide toward a first posture from a second posture in conjunction with the forward rotation of the second folding roller and rotates the guide from the first posture toward the second posture in conjunction with the backward rotation of the second folding roller.

A printing apparatus, including a sheet conveyer unit with a first roller unit, a printer unit, and a controller, is provided. The controller executes a first-face printing process, wherein an image is printed on a first face of a sheet; a switchback process, wherein the sheet after the first-face printing process is conveyed in a reverse direction by the first roller unit; a second-face printing process, wherein the image is printed on a second face of the sheet; a first ink amount determining process to determine whether an ink amount discharged in the first-face printing process at an end area of the sheet is one of greater than and equal to a first threshold amount; and a switchback setting process, wherein, if the ink amount is smaller than the first threshold amount, a rotation speed of the first roller unit is set at a higher rotation speed.

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.
