Abstract: Provided is a document conveying apparatus that properly discharges documents regardless of the amount of documents stacked on a discharge tray without complicated construction of a transmission mechanism for transmitting a driving force to conveying rollers. A conveying roller pair is provided at an end portion on an upstream side. A swing mechanism swings a discharge mechanism centered around a drive shaft of the conveying roller pair. An upper surface height measuring unit measures the height of the upper surface of documents stacked on the discharge tray. A control unit, by causing the swing mechanism to swing the discharge mechanism according to the height measured by the upper surface height measuring unit, performs control so that the difference between a discharge port and the upper surface of the documents stacked on the discharge tray is within a specified range.

Abstract: A document conveyance apparatus includes a first conveyance path, a first image reading part, a second conveyance path, a third conveyance path and a branch guide. The first conveyance path extends linearly. The first image reading part reads an image on one face of the document conveyed along the first conveyance path. The second conveyance path branches from the first conveyance path at a branch point on a downstream side of the first reading part in a conveyance direction of the document and is formed to be curved. The third conveyance path branches from the first conveyance path at the branch point and extends linearly in a same extending direction as an extending direction of the first conveyance path. The branch guide is provided at the branch point and guides the document to the second conveyance path or to the third conveyance path.

Abstract: A transfer unit includes a seamless transfer belt, a plurality of transfer rollers, a backup roller, a plurality of pairs of first bearing holders, a pair of second bearing holders and a pair of sliders. Each of the sliders is reciprocated such that each of the first bearing holders slides on the corresponding one of the first step ribs to be reciprocated in a direction toward and away from the transfer belt and the second bearing holder slides on the second step rib to be reciprocated in the direction toward and away from the transfer belt. The first step rib arranged most upstream in the direction of travel of the transfer belt and the second step rib are arranged side by side in the axial direction of the transfer roller, and overlap each other when viewed in the axial direction.

Abstract: A belt conveying device includes a correction mechanism, a belt cleaning unit, a roller retaining member, a cleaning support member, and a posture maintaining unit. When a belt is meandering, the correction mechanism allows one end side of a meandering correction roller in an axial direction to move in the direction perpendicular to the axial direction, so as to correct meandering of the belt. The posture maintaining unit connects the roller retaining member and the cleaning support member, so as to maintain posture of the belt cleaning unit with respect to the meandering correction roller.

Abstract: An optical scanning device irradiates an image carrier with laser light to form an electrostatic latent image. The optical scanning device includes a casing, a transmissive member, a wire-shaped member, a driving portion, a guide rail, a cleaning holder, a cleaning member, and a stopper. The cleaning member is fixed to the cleaning holder and cleans the transmissive member by sliding with respect to the transmissive member along with movement of the cleaning holder. The stopper is disposed on one side of the guide rail in an extending direction of the guide rail and restricts the movement of the cleaning holder. Another side of the guide rail in the extending direction of the guide rail is open in the extending direction of the guide rail.
