Abstract: An image forming apparatus having an automatic document feeding unit so as to successively read documents is disclosed. The image forming apparatus includes an image forming unit to form an image on a printing medium, an image reading unit pivotally coupled to an upper portion of the image forming unit to expose and shield a top of the image forming unit, an automatic document feeding unit pivotally coupled to an upper portion of the image reading unit to expose and shield a top of the image reading unit, and a locking device to selectively expose any one of the top of the image forming unit and the top of the image reading unit. Since the locking device prevents the top of the image forming unit and the top of the image reading unit from being simultaneously exposed, the automatic document feeding unit can be prevented from being damaged due to the simultaneous exposure of the top of the image forming unit and the top of the image reading unit.

Abstract: Disclosed is a device for feeding a recordable paper to an image forming apparatus. The device according to the present invention is designed such that a document feeder is disposed on a knock-up plate on which recordable papers are stacked so as to feed a document using such a identical path of feeding the recordable paper when printing as that of feeding a document to be scanned. When scanning the document, the document feeder is positioned over the knock-up plate having the recordable papers stacked thereon to be adjacent to the feed roller. Accordingly, there is an advantage in that a structure of the image forming apparatus is simply, resulting in providing a convenience for an user.

Abstract: An automatic document feeder has a separation roller that separates a document into individual sheets. The document is supplied from a document supply tray. A friction pad is formed to contact one side of the separation roller to supply a friction force for separating the document. A pad holder supports the friction pad. A cover member covers the separation roller. An interlocking unit pressurizes or separates the pad holder toward or from the separation roller in association with an opening or a closing of the cover member. The interlocking unit includes a pinion gear rotating in association with the opening or the closing of the cover member. A rack gear linearly moves in a normal direction of a plane contacting the separation roller and the friction pad according to a rotation direction of the pinion gear. A connecting unit connects the rack gear and the pad holder. An elastic member elastically supports the pad holder to face the separation roller.

Abstract: A sheet feeding device that may be constructed using a first tray mounted in a frame and biased by an elastic member to bring the paper stacked on the first tray into engagement with a pickup roller. A finger is pivotally attached to the frame to force the paper loaded from the first tray to be loaded sequentially. A second tray is attached to the frame and has an end that forms a document guide that is interposed between the finger and the pickup roller. Alternatively, the second tray can end before the pickup roller and a film can be attached to the second tray to form a document guide that extends between the pickup roller and the finger. Regardless of the method used to form a document guide, the document guide allows a user to intersperse a manually fed document between documents that are being loaded from a separate tray using an automatic document loading process.
Abstract translation: 一种纸张馈送装置，其可以使用安装在框架中并被弹性构件偏置的第一托盘来构造，以使堆叠在第一托盘上的纸与拾取辊接合。 手指可枢转地附接到框架，以迫使从第一托盘装载的纸张被顺序加载。 第二托盘附接到框架并且具有形成介于手指和拾取辊之间的文件引导件的端部。 或者，第二托盘可以在拾取辊之前结束，并且膜可以附接到第二托盘，以形成在拾取辊和手指之间延伸的文件导向件。 不管用于形成文档指南的方法如何，文档指南允许用户使用自动文档加载过程来从正在从单独托盘加载的文档之间散布手动馈送的文档。
