SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS
A sheet feeding apparatus includes a sheet supporting portion configured to support a first sheet and a second sheet that are superposed in a stacking direction, a rotary feeding member, a separation portion, a return portion configured to return the second sheet, separated by the separation portion from the first sheet, toward the sheet supporting portion, and a regulating portion comprising a regulating surface, the regulating portion being configured to move between a regulating position configured to regulate the position of leading edges of the first sheet and the second sheet by the regulating surface, and an allowing position being configured to allow feeding of the first sheet and the second sheet supported on the sheet supporting portion, the regulating surface being extended in the stacking direction in a state where the regulating portion is positioned at the regulating position.
IMAGE FORMING APPARATUS
An image forming apparatus includes a paper tray, an elevating plate, a cam, and a shutter. The paper tray is configured to hold sheets. The elevating plate on the paper tray is arranged to ascend and descend between a descended position and an ascended position higher than the descended position. The cam is movable between a first position and a second position. The shutter includes a shielding portion. The shielding portion is located at a shielding position when the cam moves to the first position. The shielding position is a position that overlaps with a region in a height direction occupied by the cam at the second position. The shielding portion retracts from the shielding position when the cam has moved from the first position to the second position.
SHEET FEEDING APPARATUS AND IMAGE FORMING APPARATUS
A sheet feeding apparatus includes a sheet supporting portion configured to support a sheet, a feeding member configured to contact an upper surface of the sheet supported on the sheet supporting portion and feed the sheet, a drive motor configured to rotate in a first direction and in a second direction opposite to the first direction, and a lifting mechanism connected to the drive motor and configured to lift the sheet supporting portion and lower the feeding member in a case where the drive motor rotates in the first direction, and to lower the sheet supporting portion and lift the feeding member in a case where the drive motor rotates in the second direction.
Image forming apparatus and sheet feeding apparatus
An image forming apparatus includes a manual feed tray for placing a sheet to be subjected to image formation; a pickup roller configured to abut against the placed sheet to feed the sheet; a controller; and a human detection sensor. The controller maintains an abutment state, in which the pickup roller is held in abutment against the sheet, until a time period during which the abutment state is maintained reaches an abutment timeout. When a time period during which no human is detected by the human detection sensor in the vicinity of the image forming apparatus reaches a human detection timeout even before the time period during which the abutment state is maintained reaches the abutment timeout, the controller brings the pickup roller into a non-abutment state against the sheet.
Apparatus for supplying film
Disclosed is a film feeding apparatus including a turntable including a driving member and a rotation bar having a central part shaft-coupled to a rotating shaft of the driving member to be driven to rotate around the rotating shaft and driven to rotate to repeatedly perform an operation in which the rotation bar rotates by a predetermined reference angle through the driving member and is then stopped for a predetermined reference time, a film tray that is installed in a predetermined first operation region to position one of opposite ends of the rotation bar on the film tray in a state in which the rotation bar is stopped for the reference time and on which a plurality of films are located in multiple layers, gripping units coupled to the opposite ends of the rotation bar, respectively, to transfer the films along a predetermined circular trajectory around the rotating shaft by the rotation bar and provided to grip the films, and a film ejection unit that is installed in a predetermined second operation region to position a remaining end opposite to the one end of the opposite ends of the rotation bar in the film ejection unit in the state in which the rotation bar is stopped for the reference time and provided to eject the films to an outside, wherein, in the state in which the rotation bar is stopped for the reference time, a griping unit positioned in the first operation region among the gripping units grips a film from the film tray, and a gripping unit positioned in the second operation region among the gripping units releases a film that is pre-gripped from the film tray and transfers the film to the film ejection unit.
SHEET FEEDING DEVICE, IMAGE READING APPARATUS INCLUDING THE SHEET FEEDING DEVICE, AND IMAGE FORMING APPARATUS
A sheet feeding device includes a stacking portion, a feeding portion, a contact and separation mechanism, a separation conveying portion, a detecting portion, a size acquiring portion, and a controller. In a first mode, in a case that the detecting portion detects passing of a trailing end of the current sheet after the separating operation, the controller causes the contact and separation mechanism to start a contact operation in which the feeding portion is contacted to a sheet stacked on the stacking portion in order to feed a subsequent sheet. In a second mode, before the detecting portion detects passing of a trailing end of the current sheet after the separating operation, the controller causes the contact and separation mechanism to start, on the basis of a distance in which the current sheet is fed by the separation conveying portion, the contact operation to feed the subsequent sheet.
Recording apparatus
There is provided a recording apparatus with which it is possible to reduce an occupied space to a small size in a configuration of including a mounting unit and a receiving unit.
SHEET FEEDING DEVICE AND IMAGE FORMING APPARATUS
A sheet feeding device includes a pickup roller, a feed roller, a retard roller, a conveyance rollers pair. The pickup roller contacts a sheet at a first contact point in a pickup position and rotates to convey the sheet in a predetermined conveyance direction. The feed roller is disposed on a downstream side of the pickup roller in the conveyance direction. The retard roller contacts the feed roller at a second contact point and conveys the sheet while separating the sheet. The conveyance rollers pair contacts each other at a third contact point and conveys the sheet passing through the second contact point to a conveyance path. The first contact point, the second contact point and the third contact point are disposed on a linear line in the conveyance direction, when viewed from axial directions of the rollers.
AUTOMATIC LAMINATING MACHINE
Provided is an automatic laminating machine, including a supporting plate assembly, a case, a limiting assembly, a film separation assembly, and an input roller assembly. A lower end of the supporting plate assembly extends into and is rotatably connected inside the case. The limiting assembly and the input roller assembly are rotatably connected inside the case. The film separation assembly is arranged inside the case, and located below the input roller assembly. One end of the limiting assembly is rotatably connected to the supporting plate assembly.
SHEET FEEDER APPARATUS
A sheet feeder apparatus is provided. The apparatus comprises a width detector for a sheet placed on a sheet placement portion, a conveyor for conveying sheets while separating the sheets one by one, a first detector for a sheet having a first width at a plurality of first positions, a second detector for a sheet having a second width that is not detected by the first sheet detector, at a plurality of second positions, and a controller for determining skewing of a sheet based on a result of the detection of the sheet performed by the first detector if the width of the sheet is the first width, and determining skewing of a sheet based on a result of the detection performed by the second detector if the width of the sheet is the second width.
