A post-processing apparatus includes a processing tray for stacking a sheet and a detection sensor for detecting the presence or absence of the sheet placed on the processing tray. The post-processing apparatus includes a pinch roller for moving towards the processing tray if the detection sensor does not detect the sheet, and a longitudinal alignment roller configured to rotate by a predetermined amount while sandwiching the sheet in the processing tray with the pinch roller to elongate the sheet. By holding a rear end of the sheet in the processing tray with a paddle section and elongating the sheet towards the downstream side with the longitudinal alignment roller, the presence or absence of the sheet is detected by the detection sensor.

According to embodiments, a sheet post-processing apparatus includes a processing tray, a vertical alignment section, a horizontal alignment section and a controller. The controller is configured to control the horizontal alignment section to shift the sheet to a first alignment position a predetermined distance from the center of the processing tray in the sheet width direction, control the horizontal alignment section to align the sheet in the sheet width direction at the first alignment position, and control the vertical alignment section to align the sheet in the conveying direction at the first alignment position, control the horizontal alignment section to realign the sheet at the first alignment position.

In accordance with an embodiment, a sheet processing apparatus comprises an axis of rotation; a standby section configured to buffer a sheet; a processing section configured to execute a post processing on sheets moved from the standby section; a first paddle configured to be mounted in the axis of rotation and be rotated around the axis of rotation to contact with the sheet supplied from the standby section to draw the sheet into a stopper; and a second paddle configured to be mounted in the axis of rotation at a predetermined angle with respect to the first paddle and draw the sheet into the stopper after the first paddle is separated from the sheet after a drawing-in operation of the sheet by the first paddle.

In accordance with an embodiment, a sheet processing apparatus comprises a standby section configured to buffer a sheet; a processing section configured to receive sheets supplied from the standby section and execute a post processing on the sheets; a rotational shaft configured to rotate around an axis of rotation; a paddle arranged in the rotational shaft and configured to contact the sheet and move the sheets by rotating with the rotational shaft, the paddle being configured to slide the sheets on the processing section to a stopper for aligning the sheets; and a controller configured to control a rotational speed of the rotational shaft to rotate the paddle at a first speed, and control the rotational speed of the rotational shaft to rotate the paddle at a second speed slower than the first speed while the paddle contacts the sheets on the processing section for aligning.

In accordance with an embodiment, a sheet processing apparatus comprises a first tray, a second tray, a third tray, a lower supporting plate, a drive section and a control device. The second tray is located at the lower part of the first tray. The third tray is located at a downstream side with respect to the second tray in a sheet conveyance direction. The lower supporting plate can support the sheet from the lower part. The drive section drives the lower supporting plate. The control device controls the drive section to arrange the lower supporting plate at the downstream side with respect to a conveyance starting point of the sheet in the sheet conveyance direction in a case of skipping the first tray and the second tray to convey the sheet to the third tray.

A pharmaceutical filling system for a high volume pharmacy is described. The system can include a paper feed device and method. The system may include a paper collator with at one selectively openable shelf. A control device may monitor the capacity of the selectively openable shelf, and instruct a printer to hold printing additional print jobs. The selectively openable shelf may then be opened to allow the printed literature resting thereon to fall to a lower shelf, and the printer can then be restarted. Sheets of printed literature may be drawn from the paper collator, collected with any other sheets of printed literature associated with a prescription order, and mated with the prescription order for shipment.

A sheet processing apparatus includes a processing tray, a conveyance roller, an extrusion member, a pinch roller and a controller. The conveyance roller is arranged at a downstream side of the processing tray in a sheet conveyance direction, and conveys the sheet. The extrusion member extrudes an end of an upstream side in the sheet conveyance direction of the sheet placed on the processing tray to the downstream side. The pinch roller moves to a rotation position at the time of conveying the sheet by the conveyance roller to sandwich the sheet with the conveyance roller. The controller controls the pinch roller and the conveyance roller to convey the sheet using the pinch roller and the conveyance roller when the sheet placed on the processing tray is conveyed to the downstream side in the sheet conveyance direction.

According to an embodiment, a sheet processing apparatus includes a first tray, a second tray, and a pressing member. The pressing member includes a turning shaft, the turning shaft being located on the downstream side of a transport direction of the sheet to the first tray, relative to an end of the upstream side of the sheet supported in the first tray, and when the sheet is moved from the first tray toward the second tray, rotates about the turning shaft. The pressing member rotates about the turning shaft, to press the sheet toward the second tray at a position on the upstream side relative to the turning shaft.
