摘要:
Provided is an image forming apparatus. The image forming apparatus includes a print unit printing having a plurality of developer cartridges, each of which has a photoreceptor drum disposed therein. A plurality of fixing members are movable between a first position where the developer cartridges are installed and removed and a second position where the developer cartridges are fixed to the print unit. A pinion includes a female screw portion and a first sliding member includes a male screw portion that is engaged with the female screw portion, sliding backwards and forwards as the pinion rotates, and moving the fixing members to the first position or the second position.

Provided are a color registration sensing device to detect color registration of a color image to adjust color registration. An electrophotographic color image forming apparatus is also provided that includes a case with a door and the color registration sensing device is disposed on the case. The color registration sensing device includes at least one sensor to detect color registration of a color image, a holder including a cleaning medium which cleans the sensor while making a reciprocating movement between a first position and a second position, and an actuator to move the holder from the first position to the second position when a door of a case of an electrophotographic color image forming apparatus is closed. The holder is set to deviate from a transfer path of paper at the second position.
摘要:
An electrolysis-type apparatus for treating ballast water using NaOCl and a method thereof is provided. The apparatus includes: a ballast tank; an electrolyzer; a first circulation pump; a second circulation pump; and a controller. The ballast tank is installed in a ship to store seawater. The electrolyzer is connected with the ballast tank and electrolyzes the seawater. The circulation pumps are installed to allow the ballast water to flow into the electrolyzer and to discharge the electrolyzed water containing NaOCl to the ballast tank. The controller supplies power to the electrolyzer so as to control an NaOCl density and controls the circulation pumps. The apparatus and the method safely treat the seawater. Thus, environment pollution and ecosystem destruction can be minimized.
