| 20090016768 | ARTICLE OF CONSUMPTION AND IMAGE FORMING APPARATUS HAVING THE SAME - An image forming apparatus having a consumable detachably installed in the main body is disclosed. The image forming apparatus includes a main body having a first opening, a consumable which is detachably installed in the main body, a door mounted on the main body to open and close the first opening, and locking members operable in association with the movement of the door to secure the consumable in place as the door is closed. Possible damages due to the movement of the consumable such as a photosensitive cartridge during shipping and/or transporting of the image forming apparatus can be prevented by the locking members. | 01-15-2009 |
| 20090175649 | IMAGE FORMING APPARATUS - An image forming apparatus disclosed includes a body, a cover to open and close an opening of the body, a plurality of photosensitive members provided in the body, a light scanning device to irradiate a light beam to the plurality of photosensitive members, the light scanning device including a plurality of passage windows corresponding to the plurality of photosensitive members, and a shutter device to open and close the respective passage windows in accordance with opening and closing movements of the cover. | 07-09-2009 |
| 20090317128 | IMAGE FORMING APPARATUS - An image forming apparatus in which an exposing unit is mounted on a cover unit for improved space utilization. The image forming apparatus includes a body, a plurality of developing units arranged in the body along vertical direction of the body, a cover unit that opens or closes a side of the body an exposing unit provided at the cover unit so as to move in association with the closing or opening movement of the cover unit. The image forming apparatus may also include an engagement member to limit the movement of the exposing unit and a shutter unit to selectively open an optical path of the exposing unit upon closure of the cover unit. | 12-24-2009 |

| 20090039333 | PHASE CHANGE MEMORY DEVICE AND METHOD FOR MANUFACTURING THE SAME - A phase change memory device includes a silicon substrate having a bar-type active region and an N-type impurity region formed in a surface of the active region. A first insulation layer is formed on the silicon substrate, and the first insulation layer includes a plurality of first contact holes and second contact holes. PN diodes are formed in the first contact holes. Heat sinks are formed in the first contact holes on the PN diodes, and contact plugs fill the second contact holes. A second insulation layer having third contact holes is formed on the first insulation layer. Heaters fill the third contact holes. A stack pattern of a phase change layer and a top electrode is formed to contact the heaters. The heat sink quickly cools heat transferred from the heater to the phase change layer. | 02-12-2009 |
