20100038239 | DEVICE FOR FABRICATING FLEXIBLE FILM - A device for fabricating a flexible film is provided. The device includes a serving unit providing an insulation film; a main processing unit including at least one of a dust removing unit, an etching unit, a neutralizing unit, a coupling unit, a catalyst bonding unit, a plating unit, and a drying unit; an assistant power unit controlling a tension of the insulation film; a top transporter disposed at an upper part of the main processing unit; and a bottom transporter disposed at a lower part of the main processing unit, wherein the top transporter includes a squeezing unit pressing a material on the insulation film. The device can improve the quality of a flexible film by pressing the flexible film using the squeezing unit. | 02-18-2010 |
20100072246 | DEVICE FOR TRANSFERRING FILM - A device for transferring a film is provided. The device includes a roller transferring a film; a balancing unit connected to the roller by fixed supporters, the fixed supporters being disposed on both sides of the roller; and springs disposed on both sides of the balancing unit, wherein, if the film is out of balance, the balancing unit restores balance to the film by vibrating the both sides of the balancing unit. That is, if a film becomes out of balance during the transfer of the film, the device may restore balance to the film with the aid of the balancing unit which can vibrate on both sides of the balancing unit due to the springs. | 03-25-2010 |

20130164035 | Image Forming Apparatus And Power-Transmission Assembly of The Same - An image forming apparatus having an improved power-transmission assembly to drive a developing cartridge mounted in a main body of the apparatus. The apparatus includes a main body, at least one driving coupling unit rotatably located in a side region of the main body, at least one driven coupling unit connected to a rotator inside a developing cartridge, and a coupling holder in which the driving and driven coupling units are connected to each other to enable a power-transmission from the driving coupling unit to the driven coupling unit. The driving coupling unit includes a first spherical portion to come into contact with one side of an inner surface of the coupling holder when received in the coupling holder. The driven coupling unit includes a second spherical portion to come into contact with the other side of the inner surface of the coupling holder when received in the coupling holder. | 06-27-2013 |

20140334852 | IMAGE FORMING APPARATUS - An image forming apparatus is provided. The image forming apparatus includes a photosensitive body unit including a photosensitive body, at least one developing unit including a developing roller that is configured to contact the photosensitive body or to be separated from the photosensitive body, and a press device to press the developing unit in order to contact or separate the photosensitive body and the developing roller to/from each other. The press device includes at least one lever configured to rotate about an end portion thereof and press the developing unit by rotation, and at least one cam configured to allow the lever to rotate by rotation thereof. Since the lever gradually rotates by rotation of the cam, force applied to the developing unit through the lever is also gradually and smoothly increased or decreased. Accordingly, shock, which may occur by rough movement of the developing unit, is remarkably reduced. | 11-13-2014 |
20150321862 | SHEET PICKUP APPARATUS AND IMAGE FORMING APPARATUS HAVING THE SAME - A sheet pickup apparatus and image forming apparatus are provided. The sheet pickup apparatus includes a roller support member rotatably disposed in a sheet feeding unit and comprising roller support portions connected by a hinge, a driving shaft rotatably disposed in an end of the roller support member to transmit rotational force to the roller support member, a pickup roller rotatably disposed in another end of the roller support member, a damper member disposed to absorb impact force by limiting rotation of the roller support member, and a power transmitting member disposed in the roller support member to transmit the rotational force to the pickup roller. | 11-12-2015 |
