Claim:
A paper sheet storing apparatus configured to collect and accumulate multiple different types of paper sheets in different sizes, the paper sheet storing apparatus comprising: a paper sheet cartridge configured to have a feeder provided on a side wall thereof for externally feeding paper sheets and arranged to accumulate and keep the paper sheets therein; a stack guide member configured to introduce the paper sheets, which are fed by the feeder into the paper sheet cartridge, downward in the paper sheet cartridge and to press down surface of an uppermost paper sheet located on a top of the paper sheets accumulated and kept in the paper sheet cartridge; a detector configured to detect an angle of a guide plane of the stack guide member and a horizontal plane, where the guide plane of the stack guide member is formed to introduce the fed paper sheets downward in the paper sheet cartridge; and a lift controller configured to refer to the angle detected by the detector and control the lift mechanism to keep the angle constant, the stack guide member being structured in a specific shape to enable the surface of the uppermost paper sheet to be pressed downward in a vertical direction, with regard to all the multiple different types of paper sheets, and being arranged to be swung in the vertical direction, wherein the paper sheets are substantially rectangular in shape and are conveyed into the feeder in a substantially widthwise direction of the paper sheets or in a substantially longitudinal direction of the paper sheets as a conveying direction, and the stack guide member has a projection formed to press down the surface of the uppermost paper sheet, which is located on the top of the paper sheets accumulated and kept in the paper sheet cartridge, at least one point close to a centerline substantially parallel to the conveying direction.
