Abstract
A medium stacker is disclosed, which has a structure that effectively processes load externally applied to a stacker tray so as to prevent damage of the medium stacker and an external object from occurring and increases the ascending range of a stacker tray without change of a power transmission structure. The medium stacker includes a basic module frame fixed to a medium unit of a main body of an output device, a stacker tray fixed to the basic module frame to enable the ascending operation, on which ejected papers are stacked, a first guide means provided in the basic module frame, guiding the ascending operation of the stacker tray, a lifting belt ascending the stacker tray along the first guide means, and a belt driving pulley fixed to the lifting belt. The lifting belt includes a first part moving along the belt driving pulley, having one end fixed to the stacker tray, and a second part of an elastic member which is not moving along the belt driving pulley, having one end fixed to the basic module frame.
