Media separation apparatus
A media separation apparatus may include: a pickup roller disposed at one side of the loaded media, and configured to sequentially pick up and transfer the loaded media; a feed roller disposed separately from the pickup roller in a media feeding direction, and configured to feed the media picked up and transferred by the pickup roller toward a transfer path; and a media separator disposed at a position facing the feed roller, having a plurality of separation rollers and a separation belt wound around a part of the circumference of each of the separation rollers, and configured to separate a following medium from a leading medium through friction of the separation belt, the following medium being in close contact with the leading medium fed by the feed roller and transferred at the same time as the leading medium.
Belt conveyance apparatus and image forming apparatus
A belt conveyance apparatus includes a plurality of support rollers, an endless belt, a regulation portion configured to regulate a shift of the endless belt in a width direction, a regulation receiving member configured to contact the regulation portion to receive a regulation force by the regulation portion, and support members disposed on an upstream side, in a conveyance direction of the endless belt, of the support rollers provided with the regulation portion to oppose each other on an inner peripheral surface side and an outer peripheral surface side of the end portion side of the endless belt in the width direction, and configured to regulate a position of the regulation receiving member when the regulation receiving member enters a contact portion with the regulation portion.
IMAGE FORMING APPARATUS
An image forming apparatus includes an image forming portion, an endless belt and a plurality of stretching rollers. The stretching rollers includes a tiltable steering roller, a sliding member, a first stretching roller having a smallest diameter, and a second stretching roller having a largest diameter of the diameters. With respect to rotational axis directions of the stretching rollers, lengths of contact portions of the stretching rollers with the belt are shorter than a width of the belt, the length of the contact portion of the first stretching roller with the belt is a first length, the length of the contact portion of the second stretching roller with the belt is a second length shorter than the first length, and end positions of the contact portions of the first and second stretching rollers with respect to the rotational axis direction are different from each other.
RECORDING APPARATUS
Provided is a recording apparatus that includes a transport belt for transporting a medium, a pressing roller configured to press the medium against the transport belt, and a support portion capable of supporting the transport belt. In the stated recording apparatus, the transport belt and the support portion make contact with each other when the pressing roller is pressed against the medium. By making the recording apparatus have the constitution as described above, it is possible to make the transport belt support the medium with certainty and suppress an increase in friction force between the transport belt and the support portion capable of supporting the transport belt.
RECORDING APPARATUS
A recording apparatus which includes a transport belt which transports a medium; a pressing roller which presses the medium to the transport belt; and a support unit which can support the transport belt, in which at least a part of a portion of the support unit, which faces the pressing roller through the transport belt is subjected to friction relief processing. By setting to a recording apparatus with such a configuration, it is possible to suppress an increase in friction force between the transport belt and the support unit which can support the transport belt.
Medium conveying device and medium transaction device
A medium conveyance device including: a conveyance guide that defines a conveyance space through which a paper sheet shaped medium should pass when conveying the medium along a conveyance direction; and an outside region that is a region, out of a guide face forming a boundary face to the conveyance space in the conveyance guide, contacted by an end portion of the medium in an orthogonal direction orthogonal to the conveyance direction, and that guides the end portion of the medium to so as to be positioned inside the conveyance space.
Sheet handling apparatus
A sheet handling apparatus includes: a transport path along which a sheet is transported; a first transport member disposed on one side of the transport path; and a second transport member disposed opposed to the first transport member with the transport path interposed therebetween. The first transport member and the second transport member are driven to rotate. The sheet is transported by the first transport member rotating with an outer peripheral surface thereof being in contact with a first face of the sheet, and by the second transport member rotating in a direction opposite to a rotation direction of the first transport member, with an outer peripheral surface thereof being in contact with a second face of the sheet different from the first face.
Layboy with adjustable lower conveyor and method for operating the layboy
A layboy conveyor includes a first end and a second end and an upper conveyor having a top and a bottom and a first end and a second end and a lower conveyor having a top and a bottom and a first end and a second end. The lower conveyor top is disposed adjacent to the upper conveyor bottom and defines with the upper conveyor bottom a transport path configured to transport a sheet of material in a direction from the first end of the layboy conveyor to the second end of the layboy conveyor. A drive is operably connected to the upper conveyor and to the lower conveyor, and the drive is configured to drive the upper conveyor bottom and the lower conveyor top in the direction. A length of the lower conveyor top is adjustable.
SHEET CONVEYING APPARATUS
In order to provide a configuration capable of suppressing reductions in productivity of sheets, a pair of regulation guides are capable of guiding opposite end edges in a sheet width direction Y of a sheet S1 conveyed by a conveyance belt and spheres, while being nipped. Further, the pair of regulation guides are capable of shifting to guide positions for guiding the opposite end edges of the sheet, and retract positions retracted from the opposite end edges of the sheet more than the guide positions. A sheet detecting sensor is disposed on the downstream side of the conveyance belt in a conveyance direction X to detect the presence or absence of the sheet.
SHEET CONVEYING APPARATUS
In order to provide a configuration capable of correcting skew and lateral displacement of a sheet, a pair of regulation guides are capable of guiding opposite end edges in a sheet width direction of a sheet S conveyed by a conveyance belt and spheres, while being nipped. Further, the pair of regulation guides are capable of shifting to guide positions for guiding the opposite end edges of the sheet, and retract positions retracted from the opposite end edges of the sheet more than the guide positions, wherein a control section conveys the sheet by the conveyance belt in a state in which the pair of regulation guides are positioned in the retract positions, and brings a front end of the sheet in a state of being conveyed by the conveyance belt into contact with a conveyance roller pair with drive halted.
