摘要： A paper feeding cassette includes a frame provided with a bottom plate to support paper and a plurality of walls to define a paper loading size. The paper feeding cassette also includes a loading size adjustment device to pivotally connect at least one of the walls to be hinged on the bottom plate, so that the at least one wall is movable between a vertical position to limit the paper loading size, and a horizontal position to not limit the paper loading size, enabling a variation of the paper loading size. Since the loading size of the paper feeding cassette is varied in accordance with a size of papers to be used, papers of various sizes may be used without having to increase a size of the cassette and an office machine which uses the cassette.

摘要： A sensor cleaning apparatus for an ink-jet printer is capable of preventing a sensing error by wiping scattered ink from a surface of a sensor that is attached to a carriage. The sensor cleaning apparatus has a sensor wiper wiping the surface of the sensor, and a wiper driving portion driving the sensor wiper. As the carriage is moved, and thus the sensor is positioned above the sensor wiper, the sensor wiper is oscillated by the wiper driving portion in a predetermined amplitude, thereby cleaning the surface of the sensor. The sensor wiper oscillates in a perpendicular or parallel direction with respect to an advancing direction of the carriage.
