Claims

[Scope of utility model registration request]

A stack of originals placed in a stack on the original stacker is sent out in the feeding direction, and the separating means separates the originals one by one from the bottom layer of the original stack, and the originals are fed to the processing section via the transport path for processing. Thereafter, in the document conveying device that circulates and stacks the documents on the document stacker again in a closed loop, a pushing member stacks the bundle of documents fed in the feeding direction and pushes them to a separating position of the separating means; What is claimed is: 1. A document conveying device, comprising: a friction member for regulating inertial movement of the pushing member, and configured such that the document pushed out by the pushing member always stops at a predetermined stop position.
