A web transport control device having a plurality of rotary frame units each of which includes a carrier frame, a rotary frame parallel thereto and carrying an input roller and an output roller for a material web, and pivotably supported on the carrier frame, a web guiding system arranged such that each of the material webs is fed to one of the input rollers, deflected thereat and then deflected again at the output roller, wherein the rotary frame units are nested one in the other such that web sections of the webs that extend between respective input and output rollers are parallel to one another and the spacing between two neighboring web sections is not larger than the sum of diameters of the input and output rollers, and the input rollers are offset relative to one another in the direction parallel to the web sections.

A sheet detection device includes, as detection pieces, a first detection piece integrally provided on a rotary shaft and a second detection piece attached to the first detection piece via a biasing member. The second detection piece is capable of rotation in conjunction with the first detection piece under a biasing force of the biasing member. When the second detection piece is brought into contact with a ceiling at an upper part of the rotary shaft, the second detection piece stops further rotation while the first detection piece is capable of rotation together with the rotary shaft against the biasing force.

A medium ejection apparatus includes a housing, an ejection roller, and an ejection tray attached to the housing to be able to rotate and having a first surface and a second surface, formed at a back side of the first surface, to stack the medium ejected by the ejection roller. The first surface and the second surface are formed by a single member. The first surface is formed with a first recessed part extending in a medium ejection direction and a first beam part extending in the medium ejection direction and sticking out from the first recessed part. The second surface is formed with a second recessed part extending in the medium ejection direction due to the first beam part and is formed with a second beam part extending in the medium ejection direction and sticking out from the second recessed part due to the first recessed part.

An image reading apparatus includes a reading device that reads an image on a document that is conveyed through a first conveying path, a switching guide that is supported so as to be able to rotate about a rotation axis, guides the document to a second conveying path by being disposed at a first position, and guides the document to a third conveying path by being disposed at a second position; and a roller that conveys the document to one of the second conveying path and the third conveying path after the reading device reads the document, wherein the second conveying path is arranged above a plane that is formed along the first conveying path, and the rotation axis is arranged below the plane and on an upstream side of a vertical plane that comes in contact with an edge of a downstream side of the roller.

An image reading apparatus includes a document transport path along which a document is transported, a feeding roller that is provided on the document transport path and that feeds the document, and a reader that is provided downstream of the feeding roller in the document transport path and that reads the document, in which a main board on which electronic components are mounted, when viewed from a width direction, which is a direction intersecting a document transport direction, is disposed in a region between the document transport path and a feeding roller tangent line, which is a straight line parallel to the document transport path and which is in contact with the feeding roller at a position separated from the document transport path. In addition, the main board may be provided in an orientation along the document transport path.

A medium transport unit includes an upstream route in which a print sheet is transported, a first switchback route, a second switchback route, a first guide route, a second guide route, a guide flap configured to switch the route so that the print sheet in the upstream route is transported either toward the first guide route or toward the second guide route, a first discharge route from which the print sheet in the first switchback route is discharged, a second discharge route from which the print sheet in the second switchback route is discharged, and a downstream route passing between the first switchback route and the second switchback route and having an upstream end connected to a junction of downstream ends of the first discharge route and the second discharge route.

A sheet storage device includes a first reel that is disposed along a first axis and around which a first tape is wound; a second reel that is disposed along a second axis and around which a second tape is wound; a drum that is disposed along a third axis so as to wound a sheet, that is sandwiched between the first tape and the second tape at least partially overlapping each other, on an outer peripheral surface of the drum together with the first tape and the second tape; a first tape path between the first reel and the drum; a second tape path between the second reel and the drum; and a changing mechanism disposed in at least one of the first tape path or the second path, the changing mechanism changing a position of a corresponding tape to a direction parallel to the third axis.

An unwinder (1) of rolls (B1, B2) including a bearing structure (3) and two pairs of arms (11A, 11B; 13A, 13B) supported movable on the bearing structure (3). The unwinder further includes a splicing machine (31). The bearing structure (3) includes a base (5) and an upright (7) extending from the base, on which a cross member (33) is supported. The cross member (33) includes an intermediate portion (33A) rigidly bound to the upright (7) and a pair of lateral supports (33B, 33C) adapted to assume at least one operating position and one non-operating position, with respect to the inter-mediate portion (33A) of the cross member (33).

A recording apparatus includes: a recording section that performs a recording operation on a medium; a housing that contains the recording section; a storage section that stores the medium; and a reading unit disposed in an upper portion of the housing. The reading unit includes: a reading section that reads an original sheet; a guide member that guides the original sheet; and an aperture through which the original sheet that has been read by the reading section passes. By being rotated relative to the housing, the guide member is switched between a first position in which the aperture is exposed and the original sheet is to be guided and a second position in which the aperture is covered.

A sheet processing apparatus includes: an input section that receives a sheet; a dispensing section that dispenses the sheet; transporters that transport the sheet input through the input section, to the dispensing section; storages that store the sheet; and diverting sections that divert the sheet transported by the transporters, to the storages, wherein diversion points at which the sheet is diverted by the diverting sections are provided at positions higher than terminal ends of the transporters.
