摘要： A sheet carrying device includes a pickup roller sending out a sheet to a carrying path one by one from a document mounting tray, a roller first driving motor rotating the pickup roller, a control section controlling the roller first driving motor, and a slip detecting device detecting whether the pickup roller slips in an amount not less than a predetermined amount in carrying the sheet. Detecting that the pickup roller slips, the control section controls the roller first driving motor to perform a slip-settling operation for decreasing a start-up acceleration of the pickup roller from a time when starting to rotate to a time when reaching a predetermined speed. This allows reliably carrying a sheet and suppressing a decrease in a carrying speed of the sheet in order to prevent a decrease in a speed of a process including sheet carrying, even when the pickup roller slips in feeding the sheet from the sheet mounting tray.

摘要： A method for determining the presence of slipping of a driven nip roller relative to the web in a web printing press includes systematically changing the speed of the nip driver while monitoring the corresponding change in web tension difference across the nip. The linearity and a slope of the relationship between the tension difference and the speed of the nip driver are determined. When the tension difference is non-linear relative to the speed of the driver or the slope of the relationship is substantially less than an expected slope, then slipping is determined to be present. An operator slip indication may be provided which includes the direction of the slip, positive or negative. The operator may then take corrective action to re-establish a non-slip condition, or automatic corrective actions may ensue.

摘要： A sheet conveyance unit for transporting a sheet unreeled from a roll of paper includes a roll holder including a pair of supporters to support both axial end portions of the roll, movable in an axial direction of the roll, a pair of first conveyance rollers, a pair of second conveyance rollers, a tensioner to tension the sheet, disposed between the first conveyance rollers and the second conveyance rollers, and a tension adjustment unit. The tensioner includes a contact plate to press against the sheet, extending over an entire width of the sheet and pivotably supported on a casing of the sheet conveyance unit. The tension adjustment unit changes the tension of the sheet by adjusting a force to press the contact plate against the sheet and includes a first adjuster to change the tension of the sheet in conjunction with the interval between the supporters.
