Abstract: An air conditioning system for electric vehicles reduces a thermal load endured by the air conditioning system using desiccant-coated heat exchangers and improves energy efficiency using waste heat resulting from cooling of an electronic device when the desiccant-coated heat exchanger is regenerated.

Abstract: A vehicle air conditioner is equipped with a photocatalyst which is irradiated with light so that bacteria generated in the photocatalyst is removed. In particular, an entire area of the photocatalyst is irradiated with the light using a small number of light sources so that sterilization effect of a filter can be improved.

Abstract: Disclosed herein is an image forming apparatus having a structure improved such that a user easily opens and closes a printing media cassette. The image forming apparatus includes an apparatus body, a printing media cassette to receive printing media, the printing media cassette being movably coupled to the apparatus body, a first lever provided at the printing media cassette, a second lever provided in the apparatus body, the second lever being coupled to the first lever, turning, and being separated from the first lever when the printing media cassette is closed.

Abstract: Disclosed herein is an image forming apparatus having a structure improved such that a user easily opens and closes a printing media cassette. The image forming apparatus includes an apparatus body, a printing media cassette to receive printing media, the printing media cassette being movably coupled to the apparatus body, and at least one lever movably disposed in the apparatus body, the lever contacting the printing media cassette to pull the printing media cassette into the apparatus body and then being separated from the printing media cassette when the printing media cassette is closed.

Abstract: An image forming apparatus may include a main body having a developing apparatus, a driving source configured to generate power in the main body, a driven unit configured to receive the power from the driving source to be operated, a supply cassette configured to be detachable from the main body and in which printing media are stacked, and an opening/closing unit configured to receive power from the driving source configured to drive the driven unit to move the supply cassette back and forth. Accordingly, the supply cassette can be automatically opened and closed to provide user convenience.

Abstract: An image forming apparatus may includes an image carrying body, a intermediate transferring unit which includes an intermediate transferring belt to which a visible image on the image carrying body is transferred, a driving roller to drive the intermediate transferring belt, and a first roller support unit to support a rotation shaft of the driving roller. The image-forming apparatus also includes a medium transferring unit to transfer a visible image on the intermediate transferring belt to a printing medium and includes a transferring roller to move between a pressing position pressing the driving roller to interpose the intermediate transferring belt therebetween and a separated position separated from the pressing position, and a second roller support unit to support a rotation shaft of the transferring roller. The pressing position of the transferring roller can be regulated by a contact of the first roller support unit and the second roller support unit.
