A document feeder includes a document placing tray on which a document is placed; a document discharging tray on which a document discharged from a document discharging port in a discharging direction is stacked; and a light source that radiates light to the document discharging tray. The document discharging tray is disposed below the document placing tray. The document discharging tray has a protruding portion protruding upward from the surrounding area. The light source is disposed within a region having a width that is the same as a document having a maximum size in the width direction.

Document feeder and image forming apparatus

A document feed device including a document tray and a document guide. The document guide has a document guide side document loader and a document guide member. The document tray includes a groove. The document guide, at an end of the document guide side document loader in the width direction, includes: a scooper, and an upstream outline portion that is formed so as to gradually approach the document guide member toward an upstream side in the conveying direction with the scooper as an apex.

A sheet feeding device includes a pickup roller, a lifting/lowering mechanism, and a driver device. The lifting/lowering mechanism includes a restricting member that releasably restricts the pickup roller from being lowered from a lifted position of the pickup roller at the lifted position. In the sheet feeding device, the driver device drives the lifting/lowering mechanism so that the pickup roller is lowered from the lifted position of the pickup roller, and a drive suspend operation is performed in which the driving of the lifting/lowering mechanism by driver device is suspended after a predetermined time during which the pickup roller does not contact a sheet loading tray or a sheet on the sheet loading tray elapses from a time point when the pickup roller is released from being restricted by the restricting member at the lifted position.

Sheet feeding device and image forming apparatus

A document feeder includes an input tray (part of a document placing portion) on which a document is placed, an output tray on which the document output from a document output port in an output direction is stacked, and a substrate including a light source that emits light to the output tray. The output tray is disposed below the input tray. The substrate is fixed to the document placing portion at an oblique angle relative to a horizontal reference of the document feeder such that the optical axis of the light source extends toward the document output port.

An image-forming apparatus includes an image-reading unit. The image-reading unit includes a first member and a second member. The image-reading unit includes an original-document-feeding apparatus that conveys an original document from an original-document-loading tray to a discharge tray via a read position. In the first member and the second member, a first conveyance passage along which the original document is conveyed to the read position and a second conveyance passage along which the original document is conveyed from the read position to the discharge tray are formed. The second member includes at least two conveyance rollers. Between the two conveyance rollers, there are opening edges for partly allowing access to the second conveyance passage. The second member includes a lid for covering an opening that is defined by the opening edges.

Original-document-feeding apparatus, image-reading apparatus, and image-forming apparatus

When a first elapse time &#x394;tfrom time point tof stop of a transport motor reaches a first specified time S, a registration roller electromagnetic clutch is engaged. At time point tat which the first elapse time &#x394;treaches 50 ms, normal rotation of the transport motor is started. At time point tat which a second elapse time &#x394;tfrom the time point treaches a second specified time S(a given length of time), a reverse roller electromagnetic clutch is switched from an engaged state to a disengaged state, rendering reverse rollers and sheet discharge rollers freely rotatable. At subsequent time point t, a coil of a solenoid is de-energized, to separate the reverse rollers from each other.

Reversing sheet transport apparatus and image forming apparatus including reversing sheet transport apparatus

To provide an aqueous emulsion composition which has high adhesion strength for a wide variety of materials including molded products and affords sufficient wettability even for the object to be adhesive bonded of low surface polarity so that it can develop sufficient adhesiveness and whose emulsion is stable so satisfactorily as to provide good mechanical stability and storage stability, and to provide an adherent composition comprising the aqueous emulsion composition, at least ethylene-vinyl acetate copolymer or modified resin thereof, photo polymerization initiator, and unsaturated ethylenic monomer are mixed and dissolved or dispersed, to prepare oil drop component, followed by emulsifying the oil drop component in water by using a surface-active agent, whereby an aqueous emulsion composition, in which micelles each encapsulating at least the ethylene-vinyl acetate copolymer or modified resin thereof, the photo polymerization initiator and unsaturated ethylenic monomer are dispersed in water, is prepared.
