ABSTRACT:
A paper supply cassette includes a main body to which a paper supply roller is coupled, a container provided to slid e into/from the main body, a first lever installed at the main body to swing, a first gear installed at one side of the first lever to rotate and drive a paper supply roller by being meshed with a drive gear provided at the printer, a first elastic member to apply an elastic force to the first lever in a direction in which the first gear is meshed with the drive gear, and a locking unit to selectively lock the first lever in a state in which the first gear is separated from the drive gear. Thus, the damage to or deformation of the first gear of the paper supply cassette is prevented. Also, since the paper is stably supplied, the quality of an image can be improved.
