A sheet conveying apparatus includes a rotation member unit, a supporting shaft and a moving shaft to support the rotation member unit, a locking unit to lock the moving shaft, and an engaged portion. The rotation member unit includes an engaging portion and a sheet conveyance rotation member held by the engaging portion. When the moving shaft is at a first position, the moving shaft and the supporting shaft support the rotation member unit. When the moving shaft is moved away from the supporting shaft to a second position at which the rotation member unit is not supported by the supporting shaft, the moving shaft is locked at the second position by the locking unit after moving from the first position to the second position, and the rotation member unit is held by the engaged portion in a state in which the engaging portion engages with the engaged portion.

A self-contained no-feed-roll computer controlled corrugated board or paperboard sheet feeder apparatus 200 is configured to upgrade an installed corrugated board processing machine (e.g., 10) and includes a feed table surface 210 for boards (e.g., 2) having drive wheels (222W, 224W, 226W) in an initial variable velocity zone 220 which drives the board in a first motion profile through a first vacuum zone, and a second velocity zone 230 which then drives the board in a second motion profile through a second vacuum zone Retrofittable sheet feeder 200 also includes a controller 300 configured to receive predetermined velocity signals from the host machine 10 and generate (i) a first initial variable velocity control signal for initial variable velocity zone 220 and (ii) a second velocity control signal for second velocity zone 230 in response.

The image forming apparatus includes a feeding unit, a detection unit provided downstream of the feeding unit, a measurement unit that measures a measured time from the start of conveyance of a recording material to the detection of the recording material, and a determination unit that performs renewal determination for determining whether the feeding unit has been replaced with a new unit. Thus, replacement of the feeding unit with a new unit can automatically be detected.

A method is provided for supplying a corrugated board article or a paperboard sheet article from a feeder apparatus for receipt by an article processing host machine. The method includes feeding the article to a feeder apparatus including a sheet supporting feed table surface having a feed end and a delivery end, feed elements, and a control surface selectively movable between a covering state and an exposing state. In the exposing state the feed elements are exposed to contact and drive the article along the sheet supporting feed table. The control surface is selectively movable to an angled state to selectively angle the control surface to consecutively conceal the respective feed elements as the article moves over the feed elements.

A main body frame of a multifunction machine has first and second frames of which surfaces parallel to a Z-axis face each other. A recording head is disposed between the first and the second frames and fixed to the main body frame. An ejection tray is fixed to the main body frame on a +Z direction with respect to the recording head. A scanner is fixed to the main body frame on the +Z direction with respect to the ejection tray and forms an ejection space with the ejection tray. The recording head performs recording on a medium which is being transported toward a first direction, which is an in-plane direction of the first frame. The ejection tray is configured to be removed toward a second direction, which is the in-plane direction of the first frame, in a state where the scanner is fixed to the main body frame.

A sheet conveying apparatus includes a rotation member unit, a supporting shaft and a moving shaft to support the rotation member unit, a locking unit to lock the moving shaft, and an engaged portion. The rotation member unit includes an engaging portion and a sheet conveyance rotation member held by the engaging portion. When the moving shaft is at a first position, the moving shaft and the supporting shaft support the rotation member unit. When the moving shaft is moved away from the supporting shaft to a second position at which the rotation member unit is not supported by the supporting shaft, the moving shaft is locked at the second position by the locking unit after moving from the first position to the second position, and the rotation member unit is held by the engaged portion in a state in which the engaging portion engages with the engaged portion.

Stacking machines, delivery units, and methods suitable for handling and stacking sheets of material, and particularly sheets of magnetizable materials that are relatively heavy and susceptible to damage during a stacking operation. Such a stacking machine includes at least one delivery unit equipped with a belt and a magnetic unit. The belt and magnetic unit are adapted to operate in cooperation with each other to magnetically carry individual sheets of a magnetizable material from one side of the machine to another. The delivery unit may be part of a kit that can be installed as a unit on an existing stacking machine.

A vacuum station comprising a main housing and a pair of arms extending from the main housing. The arms are configured to hold a roller. The main housing has a front face and a rear face, with the front face having a recess therein. An air path extends from the front face to the rear face. The vacuum station also includes a removable plate having a plurality of suction holes therethrough located within the recess in the front face of the main housing. The removable plate is removably connected to the main housing by magnets. A sheet of labels can be held to the removable plate by a suction force through the air path in the main housing and the suction holes in the removable plate.

A sheet feeding apparatus includes a sheet conveying unit configured to convey a sheet along a conveyance path, a detecting unit configured to detect the sheet passing along the conveyance path, a control unit configured to determine an amount of delay of a sheet conveyed along the conveyance path based on the detection and determine information to be output based on the amount of the delay, and an output unit configured to output the information.
