Provided are a paper pickup device and an image forming apparatus having the same. The paper pickup device and the image forming apparatus having the same include a driving shaft whose end has a first combining portion and a driving shaft having a second combining portion configured to be integrally connected with the first combining portion. When the first combining portion and the second combining portion are combined with each other, the driven shaft bends and separates from the driving shaft. The first combining portion and the second combining portion may be screw-coupled to each other.

Methods are provided for extracting color distortion data from multimedia data in a content-based multimedia search and for searching multimedia data based on the extracted color distortion data. A method is also provided for generating multimedia data to be used in the content-based multimedia search. The color distortion data includes hues of the distorted color identifying which color affected such a distortion and intensity data representing how much color distortion data affected such a distortion.

The present invention relates to an image search method capable of expressing one color feature related to a spatial color feature of a still image based on a multilevel image grid and similarity-based searching images using the thusly expressed multilevel image grid. In the present invention, hierarchical grids of different levels are generated with respect to one feature for thereby obtaining a data structure in which each cell corresponding to the grid is expressed based on a reliability on a region representative color and the region representative color, so that it is possible to fast and accurately search images with respect to a user's content-based query based on a cell matching of the same level as two image grids and different levels or a color local matching of the grid match.

A paper feeding apparatus of a printer is provided and includes a double feed prevention unit. The paper feeding apparatus includes a finger unit for generating a curl at a front edge portion of the paper picked up by the pick-up roller. The finger unit presses the front edge portion of the paper that is mounted on the knock-up plate. A ventilation device is also provided to form an air gap under the picked paper by injecting air in the air chamber toward the front edge portion of the paper.
摘要:
A method for designating a representative color which is expressed based on a reliability that a representative color of an image region expresses an image region is disclosed. This method includes a step for expressing a reliability of the representative color value as a color information of the image region together with a representative color value which represents the image region in a method using a color value as an information with respect to an image region, for thereby expressing a color information of an image region using a reliability and a color segmentation method of an image region.

A fixing unit and an image forming apparatus using the same. The fixing unit includes: a pair of fixing rollers that rotate and face each other and apply heat and pressure to a toner image transferred to the sheet of paper using electrophotography; a plurality of guide members disposed in the width direction of the sheet of paper to guide the sheet of paper discharged from the pair of fixing rollers to the discharge path, each of the guide members including a first guiding portion extending toward the discharge path from an outlet of the pair of fixing rollers; a first arm rotatably installed between the guide membersthat elastically contact the sheet of paper drawn out of the pair of fixing rollers and guide the sheet of paper to the discharge path; and an elastic member elastically biasing the first arm such that the first arm contacts the sheet of paper, wherein a guide member adjacent to the first arm has a second guide portion that is shorter than the first guide portion.
摘要:
A contact shock dampening and development nip forming apparatus for developers includes a unit to dampen a contact shock and to form a development nip installed on both ends of a developing roller to be disposed between a photosensitive body and the developing roller. Accordingly, the contact shock dampening and development nip forming apparatus absorbs shocks applied to the photosensitive body from the developing roller upon changing the developers, to thereby protect the photosensitive layer of the photosensitive body and extend the lifespan of the photosensitive body. The apparatus also maintains a thickness of the development nip to thereby obtain a steady image quality, even though the developing roller and/or the photosensitive body may be formed of solid substances.

The present invention relates to 3-amido-1,2-benzoisoxazole derivatives and their salts represented by formula 1, processes for preparation and usees thereof. More particularly, it relates to a method for improving its bioavailability introducing amino acid residue to the amine group of a 3-amido-1,2-benzoisoxazole. The compounds according to the present invention are used as an antagonist against Leukotriene-B-4 receptor, an inhibitor or therapeutics of osteoroposis, thus inhibiting osteolysis and stimulating osteogensis.
摘要:
A method of searching for images in a database system determines weights of desired image features by taking into consideration both recent user relevance feedback information and whole feedback information. The method is performed in accordance with a multimedia data structure which reflects user feedback change. According to one embodiment, the data structure includes information describing the features of a specific image, recent user feedback information when the weights of the features of the specific image are learned and determined by the user relevance feedback information, and whole feedback information when th weight of the features of the specific image are learned and determined by the user relevance feedback information. The weights of the image features are determined considering both the recent user feedback information and the whole feedback information, and the image features according to the determined weights are used for the image search.
