A sheet transport device includes a sheet load tray on which a sheet is loaded, a side-edge positioning unit, and a regulating unit. The side-edge positioning unit comes into contact with a side edge of the sheet in a direction intersecting a sheet transport direction at an upper surface of the sheet load tray and positions the side edge of the sheet to a normal position. The regulating unit is provided in a rotatable manner about a rotation shaft at a lower surface of the sheet load tray and regulates an output position of the sheet by rotating a stopper of the regulating unit to a position where the stopper is capable of colliding with a downstream edge of the sheet to be output in an output direction when the side-edge positioning unit moves to a position corresponding to a minimum width of the sheet.

Sheet transport device, image reading device, and image forming apparatus

A sheet transport device includes a transport unit, a load section, and a sheet accommodation section. The transport unit has a transport path along which a sheet read at a read position is transported to an output unit. The sheet output by the output unit is loaded onto the load section. The sheet accommodation section is disposed downstream in an output direction of the sheet from an inner wall surface extending upward adjacent to the load section and has a recess capable of accommodating a sheet of a predetermined minimum size. A retrieval space through which the sheet accommodated in the sheet accommodation section is retrievable is provided by exposing the transport path in a direction opposite to a loading direction of the sheet.

A reading apparatus includes an light emitter that performs irradiation with light, a light receiver that receives light reflected from an object to be imaged, a first optical path in which specularly reflected light is guided to the light receiver as a read image, a second optical path in which diffusely reflected light is guided to the light receiver as a read image, and a switching section that switches between the first optical path and the second optical path by rotating the light emitter.

Reading apparatus switching between first optical path and second optical path

A reading apparatus that reads an image formed on a document while transporting the document, the reading apparatus includes a first reading section that reads, as a read image, one of specularly reflected light or diffusely reflected light which is reflected from the document on a reading glass through which the moving document passes, and a second reading section that reads, as a read image, the other of the specularly reflected light or the diffusely reflected light which is reflected from the document on one side of a transport path through which the document is transported.

Reading apparatus for reading reflected light

An image reading apparatus includes: a housing including a processing unit configured to process image information; an opening and closing member openably and closably provided on the housing, the opening and closing member including a reading unit configured to read an image from an image holding medium and configured to obtain image information from the image; a connection member that electrically connects the reading unit and the processing unit; and a protective member including a first protective member rotatably supported by the opening and closing member and a second protective member rotatably supported by the housing and rotatably connected to the first protective member, wherein rotation axial directions of the first protective member and the second protective member are the same direction as a rotation axial direction of the opening and closing member, and the connection member is accommodated in the protective member and protected by the protective member.

Image reading apparatus and image forming apparatus

A sheet transport device includes a sheet transport unit, a detector, and a releasing unit. The sheet transport unit transports a sheet by nipping the sheet in a nip between multiple pairs of transport rollers arranged in a sheet width direction intersecting a sheet transport direction. The detector detects a size of the transported sheet. The releasing unit releases the nip of one or more of the pairs of transport rollers outside a transport region of the sheet based on the size of the sheet detected by the detector.

A sheet transport device includes a feeding unit that feeds out a sheet from a sheet stack unit, a driving shaft that rotates the feeding unit, plural bearing members that support the driving shaft rotatably at plural positions in an axial direction and restrict movement of the driving shaft in the axial direction, and a fixing member provided integrally with each of the bearing members to removably fix each of the bearing members to an opening and closing member that is opened and closed relative to the sheet stack unit.

A sheet transport device includes a transport unit that transports a sheet to a reading position by a first transport roller, a driving unit that switches a rotating direction, a rotating unit that rotates the first transport roller in one direction, the rotating unit including a one-direction gear that directly meshes with a first planet gear when the driving unit rotates in a first direction and meshes with a second planet gear when the driving unit rotates in a second direction, a switch unit that switches between states in which rotation of the one-direction gear is or is not transmitted to the first transport roller, and a displacement-force applying part that applies a force for displacing the first planet gear to mesh with the one-direction gear when the first planet gear touches the switch unit.

The invention is directed to a conveyance device including: a pair of conveyance members; a connection member as defined herein; an operating member as defined herein; a to-be-stopped member as defined herein; a stopping member as defined herein; and a contact/separation control unit, and a document conveyance device including: a document loading portion in which documents are loaded; a document discharge portion to which the documents are discharged; a discharge member that is disposed on a downstream side of a document reading position in a document conveyance direction and that discharges each of the documents; a reversal passage as defined herein; a discharge member control unit as defined herein; and a transmission system as defined herein.
