Claims

[Scope of utility model registration request]

A stack of documents placed in a stack on a document stacker is sent out in the feeding direction, and a separation means consisting of a sorting belt and a stopper roller separates the documents one by one from the bottom layer of the document stack and processes them through the conveyance path. In the document conveying device that circulates and stacks the documents on the document stacker in a closed loop after being fed to the document stacker and processed therein, a gate member for pressing and fixing the document stack is provided above the separating means so as to be movable up and down. A document conveying device characterized in that a gate pressure buffering member is provided on a pressing portion by a gate member at approximately the same height as the separating belt, so as to disperse the total load due to the gate pressure applied to the document surface during document separation.
