Abstract: A medium stacking apparatus comprises a stacking roller for stacking a medium in a stacking space, a supporting part for supporting a lower portion of the medium transferred by the stacking roller, a plurality of stacking guides for supporting the medium disposed on the supporting part in a standing state, a plurality of moving devices for moving the plurality of stacking guides, and a control part controlling the plurality of moving devices. The control part controls the plurality of moving devices to move a second stacking guide toward a first stacking guide to allow the stacked medium to stands up in a state where the medium is supported by the first stacking guide of the plurality of stacking guides.

Abstract: Provided is an electrostatic discharging apparatus, which comprises a rotation shaft, a transfer roller, and an electrostatic discharging member. The rotation shaft transmits driving force. The transfer roller is disposed on the rotation shaft to transfer a medium. The electrostatic discharging member is disposed on the rotation shaft to rotate together with the rotation shaft, and comprises a plurality of brushes for removing static electricity.

Abstract: Provided is a medium transferring apparatus, which comprises a plurality of side guides, one or more transfer rollers, and one or more aligning rollers. The side guides constitute both side surfaces of a medium transferring path. The transfer rollers are rotatable between the side guides, and transfer a medium in a medium transferring direction. The aligning rollers align the medium in a direction inclined from the medium transferring direction.
