Abstract: A color registration sensor of an image forming apparatus, and a method of detecting registration test patterns of a plurality of colors formed on a transfer medium, by using the color registration sensor. The color registration sensor detects a current generated by an electric force of a charged toner forming registration test patterns by using an electrode, as the registration test patterns of a plurality of colors formed on the transfer medium approach the color registration sensor, and detects a location of each of the registration test patterns of the plurality of colors by using a voltage signal obtained by converting the detected current.

Abstract: An air current changeable full front blowing type air conditioner is provided. The air current changeable full front blowing type air conditioner includes: a case configured to comprise a heat exchanger disposed inside the case; a main air blower configured to be disposed in rear of the heat exchanger inside the case and discharge a main air current from a full front of the case; and at least one auxiliary air blower configured to be positioned around the main air blower of the case and discharge an auxiliary air current for changing a direction of the main air current. The auxiliary air blower discharges the auxiliary air current in a direction where the auxiliary air current interferes with the main air current discharged from the full front of the case.
