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.

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

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.
