摘要:
A pair of discharge rollers is provided at a position most downstream in a conveying direction of a sheet conveying path defined by guide surfaces. The discharge rollers discharge a sheet from the sheet conveying path. A discharge chute portion, including upper and lower discharge guides, guides the discharged sheet toward a discharge tray. An elastic support piece is provided in the discharge chute portion and elastically urges a trailing edge of the discharged sheet toward the upper discharge guide. The pair of discharge rollers is arranged such that a direction in which the drive roller contacts the follower roller is inclined toward upstream in the conveying direction with respect to a direction of a normal line of a lower one of the guide surfaces that is located in the sheet conveying path at a position the most downstream in the conveying direction.

In an image reader that can adjust a distance between a platen glass and a close-contact-type image sensor (CIS) without disassembly, a CIS unit includes a CIS and a resilient body which biases the CIS toward the platen glass. A CIS roller holder includes a spacer, and a CIS holder which holds the spacer movably in the vertical direction as well as in the sub scanning direction with respect to the platen glass and is fixed to the CIS unit. Irregularities are formed on surfaces of the CIS holder and the spacer which face each other and are engageable by fitting. When the CIS unit is moved in the sub scanning direction and the CIS roller holder is brought into contact with one rib ,the CIS roller holder is brought into contact with the spacer at projections or recesses, thus changing a distance between the platen glass and the CIS.

In an image reader having a static-document reading function and a moving-document reading function, a static-document pressing member is movably arranged on a cover portion and a sheet passing opening is opened or closed by moving the static-document pressing member. Further, the image reader includes a moving-document pressing member for pressing a document being automatically fed when it come to a document reading position on a platen glass when the static-document pressing member is moved to open the sheet passing opening.

A tray which holds documents to be fed has a document holding portion which holds document in a stacked state thereon and guide members which are arranged on the document holding portion in the cross direction (document width direction) and at least one of which is movable in the document width direction. The document feeding tray further has an extending portion which extends from the document holding portion in the feeding direction (document length direction) to freely increase or decrease the extending amount and a adjusting mechanism which decreases the extending amount of the extending portion as a distance between the guide members becomes narrower and increases the extending portion as the distance between the guide members becomes wider.
