Paper feeding cassette

Abstract

A paper feeding cassette includes a cassette body detachably mounted to an image forming apparatus, and an alignment unit disposed on an inner surface of the cassette body to pressurize a plurality of stacked sheets of recording medium from one side thereof when the cassette body is mounted in the image forming apparatus. Accordingly, the sheets of recording medium can be more accurately picked up and a stable image quality can be obtained.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit under 35 U.S.C. § 119 (a) of Korean Patent Application No. 2005-113568 filed on Nov. 25, 2005, the entire content of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present general inventive concept relates to a paper feeding device to feed a printing medium into an image forming apparatus. More particularly, the present general inventive concept relates to a paper feeding cassette of a paper feeding device. [0004] 2. Description of the Related Art [0005] An image forming apparatus, such as a copier, a printer and a facsimile, for forming a certain image on a printing medium may typically be classified as an electrophotographic type that uses a photosensitive body, an inkjet type that directly ejects a developer onto the printing medium, a thermal transfer type, a bubble jet type, a dye sublimation type, a dot matrix type, etc. [0006] ...

AI Technical Summary

Benefits of technology

[0013] Accordingly, the present general inventive concept provides a paper feeding cassette which can perform an accurate picking-up operation so that a stable image quality can be obtained.

[0014] The present general inventive concept also provides a paper feeding cassette which can easily and accurately align sheets of a printing medium.

[0015] The present general inventive concept also provides a paper feeding cassette to prevent sheets of a printing medium from overlapping when being picked up, not by an individual sheet such that the printing medium can be properly picked up from a paper feeding cassette.

Problems solved by technology

If the printing medium stacked in the paper feeding cassette is not accurately aligned, various errors occur when the image forming apparatus performs printing or the printing medium is fed.

These errors result in a paper jam or a curl of the printing medium.
