The invention describes a roll-removal device by means of which a plurality of rolls which have been wound to completion are transported away from a winding shaft having a displacement device for displacing the rolls relative to the winding shaft, in order to withdraw the rolls from the winding shaft, having a receiving device for receiving the rolls, and having a transfer device for transferring the rolls from the displacement device to the receiving device, wherein the rolls can be rolled freely at least in certain regions, the rolls rolling about their rolling axes.

By means of this device for changing the position of the rolls axes, the roll axes of two adjacent rolls can be moved to an angle of less than 180 degrees in relation to one another.

An image forming apparatus includes an accommodation unit, feeding, conveying, and separating members, and detecting, control, image forming, and regulating units. The conveying member conveys a fed recording material. The separating member forms a nip and separates recording materials. The detecting unit detects that the recording material has been fed to the nip. The feeding member starts feeding an accommodated recording material and, where a recording material is fed to the nip, causes the feeding to be finished. An image is formed on a fed recording material. The regulating unit regulates an end on an upstream side. The control unit measures a period from a recording material feeding to detection that a recording material is fed to the nip. Based on the measured period, information is output indicating that a position of the regulating unit is deviated from a position according to a size of the accommodated recording materials.

A long-handle film packing device includes a first rod and a second rod connected with each other. The first rod is formed with an axial limit groove. The second rod is provided with a limit member corresponding to the limit groove. Through the limit member limited to the limit groove, the length of the long-handle film packing device can be adjusted quickly. Through a positioning pin, the long-handle film packing device can be positioned quickly. The present invention can be applied to different lengths of packing film rolls. In addition, the packing film roll can be first mounted, and then the length of the film packing device is adjusted. Except that the length of the present invention can be adjusted and positioned quickly, the present invention has better practicability and convenience for installation.

A sheet positioning member is provided on a sheet placing surface in such a way as to be movable in a predetermined first direction. The sheet positioning member includes a moving body, an abutting portion, an operation member, and a cam portion. The moving body moves in the first direction on the sheet placing surface. The abutting portion has an abutting surface that abuts on the side end portion when the sheet positioning member positions the sheet. The operation member is supported by the moving body so as to be pivotable around a support shaft that extends in the first direction, on a side of a back surface of the abutting portion. The cam portion displaces the abutting portion toward the side end portion by being pressed by the operation member in response to a pivoting operation of the operation member.

A removable media tray with an adjustable rear tray extension operable by a rear media restraint. The tray extension is slidably attached to a front section of the tray via a cam having a locking arm engaged in a J-slot. When in the curved portion of the J-slot the front section and tray extension are locked together. A rear media restraint slidably latching to a track in the bottom of the tray has a locking lobe that engages with a locking notch on the cam. As the media restraint is slid toward the rear, the locking lobe initially rotates the cam moving the locking arm to the straight section of the J-slot, then the locking lobe engages with the locking notch, locking the media restraint to the tray extension. Thereafter, the media restraint and tray extension move together until the end of the J-slot is reached by the locking arm.
