A manual sheet feeding device includes: a sheet feeding rotary body configured to separate and feed recording media placed on a manual sheet feeding unit one by one; a shielding unit configured to cover an outer side surface of the sheet feeding rotary body, the shielding unit having an aperture for exposing at least a part of the sheet feeding rotary body to an outside; and an opening and closing unit configured to open and close the aperture of the shielding unit.

An apparatus includes an openable and closable cover, a movable member disposed in the apparatus main body and to be exposed outside when the cover is opened, an openable and closable support member that supports the movable member, and a support shaft that supports the cover and the support member. The movable member and the support member are moved together with the cover as the cover rotates about the support shaft. The support shaft can move between a first position at which the support shaft supports the cover and the support member and a second position at which the support shaft does not support the cover and supports the support member. Moving the support shaft to the second position allows the cover to be detached from the apparatus main body.

According to one embodiment, an image processing apparatus includes an apparatus main body, a first rotating body, a second rotating body, and a connection member. The first rotating body is configured to be openable and closeable and provided in the apparatus main body. The second rotating body is provided in the first rotating body. The second rotating body is configured to be openable and closable from the first rotating body in the same direction as that of the first rotating body. The connection member is linear. The connection member is configured to connect the apparatus main body and the second rotating body to each other and to restrict a rotation angle of the second rotating body.

An image forming apparatus includes an image forming unit that forms an image on a recording medium and an image forming apparatus body in which the image forming unit is provided, and on which a first manual feeding tray and a second manual feeding tray having a configuration different from the first manual feeding tray are selectively mountable at a same mounting position.

The image forming apparatus includes a side panel and a manual feed tray that is rotatable and installed on the side panel. The side panel includes an opening portion through which a sheet placed on the manual feed tray passes when the sheet is fed into the image forming apparatus. The manual feed tray includes an end cursor that is movable, and a guide portion that guides movement of the end cursor in a direction perpendicular to a rotational center of the manual feed tray. The opening portion is sized to accommodate the end cursor. When the opening/closing angle of the manual feed tray with respect to a horizontal direction exceeds a predetermined angle, the end cursor moves along the guide portion by gravity to a position where the end cursor can be accommodated in the opening portion.

An image forming apparatus includes an attachable/detachable storage unit having a positioned portion projecting downstream in an attachment direction of the storage unit, a conveyance member, an image forming unit to form an image on a sheet conveyed by the conveyance member, and a conveyance unit to move between a first position and a second position. Engagement of the positioned portion with a positioning portion of the image forming apparatus causes the storage unit to be positioned with respect to the image forming apparatus. The conveyance unit includes a contact portion and a depressed portion. In a case where the contact portion of the conveyance unit comes into contact with the storage unit and the conveyance unit is moved from the second position to the first position by the storage unit, the positioned portion does not come into contact with the depressed portion of the conveyance unit.

An image forming apparatus is provided that forms an image on a sheet material based on a sheet material setting relating to the sheet material. The image forming apparatus includes an accepting unit configured to accept a selection of a sheet material type, a thickness measurement unit configured to measure a thickness of the sheet material, and a setting determination unit configured to determine the sheet material setting that relates to the thickness of the sheet material based on the sheet material type accepted by the accepting unit and the thickness of the sheet material measured by the thickness measurement unit.

An image forming apparatus may comprise the following elements. A stacking unit in which a sheet is stacked. A conveyance unit conveys the sheet. A time-counting unit counts a conveyance time from when the conveyance unit starts to convey the sheet until the sheet arrives at a predetermined position on a conveyance path. A determination unit determines that over stacking has occurred, if the conveyance time of the sheet exceeds a first over stacking threshold value.

A manual sheet feeding device includes: a sheet feeding rotary body configured to separate and feed recording media placed on a manual sheet feeding unit one by one; a shielding unit configured to cover an outer side surface of the sheet feeding rotary body, the shielding unit having an aperture for exposing at least a part of the sheet feeding rotary body to an outside; and an opening and closing unit configured to open and close the aperture of the shielding unit.

An image forming apparatus includes a carrying part that carries media, a supply part that forwards the media to the carrying part piece by piece, wherein when a preceding medium is detected to have been fed to the carrying part, a succeeding medium is next fed to the carrying part, and a carrying controller that stops the preceding medium at a stop position of the media before the preceding medium is carried to the image forming process. The carrying controller obtains a medium length of the preceding medium in the carrying path, and changes the stop position of the preceding medium based on the medium length such that the trailing edge of the preceding medium is maintained distant from the leading edge of the succeeding medium while the preceding medium stops at the stop position.
