摘要： A sheet conveyance apparatus includes a sheet conveyance unit, a double feeding detection unit, a first sheet detection unit, and a control unit. The double feeding detection unit detects double feeding with respect to a sheet. The control unit controls a conveyance speed of a sheet conveyed by the sheet conveyance unit at a first speed and a second speed which is slower than the first speed and at which the sheet is in motion. The control unit controls the sheet conveyance unit to decelerate the conveyance speed of a sheet conveyed by the sheet conveyance unit from the first speed to the second speed based on a detection result of the first sheet detection unit. The control unit controls the double feeding detection unit to execute a double feeding detecting operation with respect to the sheet that is conveyed at the second speed by the sheet conveyance unit.

摘要： Provided are a medium conveying apparatus, a control method, and a control program to enable determining whether multi-feed of the medium has occurred with higher accuracy. A medium conveying apparatus includes a conveying module to convey a medium, a detection module to detect transmission information of ultrasonic waves transmitted through the medium or thickness information of the medium at a plurality of positions in the medium conveyed by the conveying module, a determination module to determine whether multi-feed of the medium has occurred, by comparing a value based on the transmission information or the thickness information with a threshold, for each of the plurality of positions, and a control module to execute an abnormality process when it is determined that multi-feed of the medium has occurred. The determination module changes a determination sensitivity of whether multi-feed of the medium has occurred, according to a position in the medium at which the transmission information or the thickness information has been detected by the detection module.

摘要： A sheet feeding device includes a conveyance rotator, a separation rotator, a torque applier, a torque control circuit, and a torque transmission switcher. The conveyance rotator conveys a sheet in a sheet feeding direction. The separation rotator sandwiches the sheet together with the conveyance rotator. The torque applier applies a reverse torque to the separation rotator in a sheet reversing direction to reverse the sheet. The torque control circuit controls the reverse torque applied to the separation rotator to be equal to or less than a given value. The torque transmission switcher switches, between a transmission state and a non-transmission state, a state of a torque transmission path between the torque applier and the separation rotator. The transmission state is a state in which the reverse torque is transmitted. The non-transmission state is a state in which the reverse torque is not transmitted.

摘要： An object of the present invention is to prevent the ends of print media fed continuously from colliding with each other. The present invention is a printing apparatus including: a printing unit configured to perform print operation; a detecting unit configured to detect conveyance abnormality; a conveying unit configured to convey a preceding print medium and a succeeding print medium; a conveying path having a first area including a curved portion at which a conveying direction of the print medium is curved and a second area upstream of the first area; and an opening unit capable of opening the first area of the conveying path, wherein, in a case where a leading edge of the succeeding print medium is located in the second area at the time of the detecting unit detecting conveyance abnormality of the preceding print medium, the conveying unit conveys the succeeding print medium so that the leading edge of the succeeding print medium reaches the first area.

摘要： A paper sheet handling apparatus includes a calculation unit and a determination unit. The calculation unit calculates, on the basis of a thickness of a paper sheet that passes through a conveyance path and a contour of the paper sheet, a total area of a cumulative area of overlapping regions of the paper sheet in the contour and an area of a non-overlapping region of the paper sheet in the contour. The determination unit determines the number of the paper sheets on the basis of the calculated total area.

摘要： An image forming apparatus includes an accommodation unit, feeding, conveying, and separating members, and detecting, control, image forming, and regulating units. The conveying member conveys a fed recording material. The separating member forms a nip and separates recording materials. The detecting unit detects that the recording material has been fed to the nip. The feeding member starts feeding an accommodated recording material and, where a recording material is fed to the nip, causes the feeding to be finished. An image is formed on a fed recording material. The regulating unit regulates an end on an upstream side. The control unit measures a period from a recording material feeding to detection that a recording material is fed to the nip. Based on the measured period, information is output indicating that a position of the regulating unit is deviated from a position according to a size of the accommodated recording materials.

摘要： In a method for handling sheet goods, in particular value documents, such as bank notes, in an apparatus for processing sheet goods, such as a bank-note machine, sheet goods are removed from a container for sheet goods that is inserted in the apparatus, through an output opening of the container, checked for further processability, and in the case of a negative check result returned into the container through an input opening of the container that is separate from the output opening. The container has a pressing device for exerting a pressure on the sheet goods in the direction of the output opening, wherein the pressing device is displaceable along the height of the container such that sheet goods are both outputtable from a sheet-goods region of the container through the output opening and inputtable back into the sheet-goods region through the input opening.
