Document conveying apparatus

A document conveying apparatus that separates and conveys one document sheet after another from a stack of document sheets placed on a document stacking tray to permit image data to be read from a document surface, the document conveying apparatus comprising:

• a fan arranged at such an orientation as to pass air from an upstream side to a downstream side with respect to a document conveying direction to cool an inside of the document conveying apparatus, the air flowing along a document conveying passage on an air intake side and/or an air exhaust side of the fan, the air exhaust side of the fan pointing to a downstream-side end face of the stack of document sheets placed on the document stacking tray, at least part of the air discharged toward the downstream-side end face of the stack of document sheets placed on the document stacking tray being passed to a document ejection port located at a downstream end of the document conveying passage to permit the document sheets to be ejected therethrough into a document ejection tray.

• an outlet of the fan points to a document ejection port located at a downstream end of the document conveying passage to permit the document sheets to be ejected therethrough into a document ejection tray, and
• an exhaust duct permits the air discharged from the fan to be directed downwards to the document ejection port.
