ABSTRACT:
A media pickup apparatus includes a push plate for pushing media stored in a cassette body towards a discharge port of the cassette body. A driving source provides power to the push plate so as to allow the push plate to push the media towards the discharge port of the cassette body. A pickup roller is rotatably coupled to one side of a roller bracket and biased towards the push plate by means of an elastic member in such a manner that the pickup roller elastically makes contact with the media pushed by the push plate, in order to discharge the media from a media cassette by separating the media sheet by sheet. A sensor detects a position of the pickup roller so as to provide data for operating the driving source. The media make contact with the pickup roller with a substantially constant contact force so that media are reliably discharged from the media cassette sheet by sheet.
