Claims

[Scope of Claim for Utility Model Registration] (1) A paper feed roller and a sorting roller are installed at the output side end of the intermediate tray that stores paper that has already been copied on one side and feeds the paper for copying on the back side of an automatic double-sided copying machine, etc. In the sheet feeding device, the pressing member is configured to be movable toward and away from the upper surface of the sheet, and the sheet is directed toward the bottom roller. 1. An intermediate tray paper feeding device for an apparatus such as a copying machine, characterized in that the bottom roller is used as a separator for single-sided copied paper. (2) The pressing member is composed of a plate-like member, and
The plate-like member is provided to swing via a fulcrum, and after a predetermined number of sheets of single-sided copied paper are stored, the plate-like member is set on the single-sided copied paper. An intermediate tray paper feeding device for an apparatus such as a copying machine according to claim 1, characterized in that the intermediate tray paper feeding device is configured to function as a pressing member and a separator. (3) The pressing member is composed of a weight roller, the weight roller is supported by a link mechanism, and
An intermediate tray paper feeding device for an apparatus such as a copying machine according to claim 1, characterized in that a device for swinging the weight roller is provided. (4) Practical use characterized in that a presser plate is provided on the paper feed side of the weight roller, and the presser plate presses the leading end side of the single-sided copied paper stored in the intermediate tray. An intermediate tray paper feeding device for an apparatus such as a copying machine as claimed in claim 3.
