a feeding roller for feeding the document obliquely downward; a reading section for reading the document fed from the feeding roller; a discharge roller that discharges the read document and a discharge tray that receives the document discharged from the discharge roller; and a guide member having a tip end, a base end supported by the discharge tray, and an inclined portion provided between the base end and the tip end, the guide member being configured to be displaceable in a vertical direction, and guide a leading end of the discharged document, wherein a distance between the base end and the discharge roller is longer than a distance between the tip end and the discharge roller in both a vertical and a horizontal direction. ### Claim 2 (depends on 1) The image reading apparatus according to claim 1, wherein the inclined portion has a first inclined portion inclined at a predetermined angle relative to a mounting surface of the discharge tray and a second inclined portion inclined toward the discharge tray from the first inclined portion. ### Claim 3 (depends on 1) The image reading apparatus according to claim 1, wherein the guide member is biased by a spring and displaced by a force of the discharged document being received by the discharge tray. ### Claim 4 (depends on 3) The image reading apparatus according to claim 3, wherein the guide member is formed of a non-elastic member. ### Claim 5 (depends on 1) The image reading apparatus according to claim 1, wherein a plurality of ribs extending in the document discharge direction are formed in the discharge tray, and the guide member is formed between the ribs. ### Claim 6 (depends on 1) The image reading apparatus according to claim 1, wherein the discharge tray has a wall portion projecting upward from an end portion of the discharge tray. ### Claim 7 (depends on 1) The image reading apparatus according to claim 1, wherein the guide member has the tip end as a free end. ### Claim 8 (depends on 1) The image reading apparatus according to claim 1, wherein the inclined portion includes a first inclined portion and a second inclined portion whose inclines are different. ### Claim 9 (depends on 1) The image reading apparatus according to claim 1, wherein the base end is fixed to the discharge tray and the tip end is displaceable. ### Claim 10 (depends on 1) The image reading apparatus according to claim 1, wherein the base end is fixed to the discharge tray and the tip end is provided at the highest position of the guide member in the vertical direction. ### Claim 11 An image reading apparatus comprising: a document support section for placing a document in an inclined position; a feeding roller for feeding the document obliquely downward; a reading section for reading the document fed from the feeding roller; a discharge roller that discharges the read document and a discharge tray that receives the document discharged from the discharge roller; and a guide member having a tip end, a base end supported by the discharge tray, and an inclined portion provided between the base end and the tip end, and guides a leading end of the discharged document, wherein the base end is provided downstream of the tip end in a discharge direction, and wherein the tip end configured to be displaceable in a vertical direction and is provided at the highest portion of the guide member in the vertical direction.
