Sheet processing apparatus and image forming system including the same
A sheet processing apparatus, including: a rotary member pair configured to nip a sheet conveyed in a conveyance path and rotate to fold the sheet; and a guide portion provided between one rotary member of the rotary member pair and the conveyance path, the one rotary member including: a first part; and a second part, wherein a first distance between the first part and a rotary shaft center of the one rotary member is greater than a second distance between the second part and the rotary shaft center, and wherein the guide portion is positioned at a first position in case that the second part is positioned at a first rotational position, and the guide portion is positioned at a second position different from the first position in a distance from the rotary shaft center in case that the second part is positioned at a second rotational position.
MECHANICAL SHEET PRODUCT DISPENSER
A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.
PARTIALLY DRIED INKJET MEDIA OUTPUT MANAGEMENT
In one example, a device for partially dried inkjet media output management includes a starwheel positioned on a first side between a number of rollers positioned on a second side to corrugate partially dried inkjet media between the starwheel and the number of rollers.
Sheet processing apparatus and image forming system including the same
A sheet processing apparatus, including: a conveyance path in which a sheet is conveyed in a predetermined conveyance direction; a rotary member pair configured to nip the sheet conveyed in the conveyance path and rotate to perform folding processing on the sheet; and a guide portion provided between one rotary member of the rotary member pair and the conveyance path and configured to guide a downstream edge of a sheet conveyed in the predetermined conveyance direction, wherein, in case that a sheet is conveyed in the conveyance path in the predetermined conveyance direction, the guide portion guides a downstream edge of the sheet in the predetermined conveyance direction in a state in which the guide portion is held in contact with the one rotary member.
Draw-in device for sheet-type articles
A draw-in apparatus having at least two rotatable draw-in rollers for drawing in sheet goods, in particular bank notes, wherein the draw-in rollers are arranged relative to each other with meshing roller profiles respectively extending transversely to the draw-in direction so as to define a draw-in gap for the sheet goods, and wherein the draw-in rollers have axial cross-sectional profiles mutually matched such that a clearance between the draw-in rollers changes periodically upon a rotation of the draw-in rollers.
Sheet-conveying device that conveys sheets, image-forming apparatus using the sheet-conveying device and image-forming system that uses the sheet-conveying device
A sheet-conveying device contains a first linear sheet-conveying path on which the sheet is conveyed, a curved sheet-conveying path connecting the first linear sheet-conveying path and a second linear sheet-conveying path connecting the curved sheet-conveying path. A curved conveying guide is provided at only an outside of a curved sheet-conveying route. Conveying guide rollers are provided at an upstream side of the curved conveying guide. The conveying guide rollers contain a driving roller which is arranged at outside of the curved sheet-conveying path and a driven roller which is arranged at inside of the curved sheet-conveying path. The driven roller has a diameter more than that of the driving roller. The driven roller also has hardness less than that of the driving roller.
MEDIUM TRANSPORTATION DEVICE, RECORDING APPARATUS, POST-PROCESSING APPARATUS, RELAY APPARATUS, AND UNEVEN ROLLER
Provided is a medium transportation device including an uneven roller of which a surface coming into contact with a medium is provided with a plurality of protrusions and recesses, a facing roller nipping the medium together with the uneven roller, and a claw portion guiding the medium to be separated from the uneven roller. A non-uneven region in which the protrusions and recesses are not formed along a circumferential direction is formed at a portion of the uneven roller in an axial direction and the claw portion faces and the non-uneven region.
Sheet conveyance apparatus and image forming apparatus
The sheet conveyance apparatus includes first and second rollers, the second roller coming into contact with the first roller and thereby forming a nip portion, the second rotation axis being inclined with respect to the first rotation axis, wherein the second roller includes a first outer circumferential portion having a first outside diameter, a second outer circumferential portion arranged on one side of the first outer circumferential portion in an axial direction of the second rotation axis and having a second outside diameter larger than the first outside diameter, and a third outer circumferential portion arranged on the other side of the first outer circumferential portion, and wherein an outer circumferential surface of the first roller contacts with at least the first, second and third outer circumferential portions of the second roller, to form the nip portion.
SHEET PROCESSING APPARATUS AND IMAGE FORMING SYSTEM INCLUDING THE SAME
A sheet processing apparatus, including: a conveyance path in which a sheet is conveyed in a predetermined conveyance direction; a rotary member pair configured to nip the sheet conveyed in the conveyance path and rotate to perform folding processing on the sheet; and a guide portion provided between one rotary member of the rotary member pair and the conveyance path and configured to guide a downstream edge of a sheet conveyed in the predetermined conveyance direction, wherein, in case that a sheet is conveyed in the conveyance path in the predetermined conveyance direction, the guide portion guides a downstream edge of the sheet in the predetermined conveyance direction in a state in which the guide portion is held in contact with the one rotary member.
SHEET PROCESSING APPARATUS AND IMAGE FORMING SYSTEM INCLUDING THE SAME
A sheet processing apparatus, including: a rotary member pair configured to nip a sheet conveyed in a conveyance path and rotate to fold the sheet; and a guide portion provided between one rotary member of the rotary member pair and the conveyance path, the one rotary member including: a first part; and a second part, wherein a first distance between the first part and a rotary shaft center of the one rotary member is greater than a second distance between the second part and the rotary shaft center, and wherein the guide portion is positioned at a first position in case that the second part is positioned at a first rotational position, and the guide portion is positioned at a second position different from the first position in a distance from the rotary shaft center in case that the second part is positioned at a second rotational position.
