A method for attaching a sheet member to a cylinder body includes: preliminarily fixing a first end portion of the sheet member to a first fixation portion of a cylinder body provided in an apparatus body and having a substantially circular cross section; wrapping the sheet member around the cylinder body by rotating the cylinder body; fixing the first end portion and a second end portion of the sheet member to the first fixation portion and a second fixation portion, respectively; and installing an installation member between the apparatus body and an inner surface of the sheet member before the wrapping of the sheet member around the cylinder body.

A sheet processing apparatus includes a stacking unit configured to stack a plurality of sheets, an alignment unit including a supporting portion on which the sheets are loaded, the alignment unit being configured to align positions of the sheets loaded on the supporting portion, and a bonding unit configured to bond the sheets loaded on the supporting portion to each other. The alignment unit is configured to align a position of the second sheet stack with the first sheet stack. The bonding unit is configured to heat and pressurize the second sheet stack aligned by the alignment unit such that sheets of the second sheet stack are bonded to each other with the adhesive and the first sheet stack and the second sheet stack are bonded to each other with the adhesive.

In some examples, a sheet processing machine includes at least one infeed system including at least one transport means including at least one upper holder and at least one lower holder. The at least one transport means can be and/or is arranged in at least three states: a maximally closed state corresponding to a minimal distance, a minimally closed state corresponding to a maximal distance, and an at least one mean state corresponding to at least one mean distance between at least one upper holding surface at least of the respective upper holder, and at least one lower holding surface of the lower holder of the at least one transport means that is assigned to the respective upper holder. During a machine cycle, the at least one transport means has each of the minimally closed state, the maximally closed state, and the at least one mean state at least once.

According to one embodiment, a sheet cassette includes a sheet placing portion. The sheet placing portion can rotate around a rotation shaft while placing a sheet of a placeable maximum size in a sheet placing area to be flat. The rotation shaft extends to be perpendicular to a discharge direction and a gravity direction of the sheet. The rotation shaft is disposed between a first end portion on a downstream side along the discharge direction in the sheet placing area and a second end portion on an upstream side positioned on a side opposite to the first end portion.

A conveyance device includes a conveyance path having a curved portion and a pair of conveyers which are disposed in the conveyance path and convey a medium while nipping it, wherein the medium enters the pair of conveyers in a state of being at least partially curved in the curved portion, and the conveyance path guides the medium toward one of the pair of conveyers.

A correction structure arranged in a feeding path of a document processing device, comprising: a transmitting means consisted of at least a pair of roller sets which are arranged symmetrically on the two sides of the feeding path for transmitting the card evenly, a correcting means consisted of a platform movably arranged at the downstream to the roller set, a receptacle formed on the platform, an elastic object arranged in the receptacle for returning the platform to a predefined location, a back wall extended from the platform toward the feeding path, an opening formed on the back wall to let a card go through, and a friction pad arranged at the bottom of the opening to partly jam the opening, wherein the width of the friction pad is less than the width of the feeding path so the friction pad only contacts the center of the card while transmitting the card.
