Print medium finishing apparatus, image forming system, and moving structure employed therein

An image forming system comprising:

• an image forming apparatus configured to form an image on at least one print medium of print media;
• and
• a print medium finishing apparatus configured to align the print media including the at least one print medium having images formed thereon,
• wherein the print medium finishing apparatus comprises:
• a print medium stacking plate;
• a stacker tray disposed at a location lower than the print medium stacking plate;
• and
• a print medium discharging apparatus configured to discharge the print media on the print medium stacking plate to the stacker tray, the print medium discharging apparatus comprising:
• at least one driving gear that is rotatable;
• a moving member configured to move in a linear motion and a curvilinear motion with respect to the at least one driving gear, the moving member comprising:
• a motion converting gear configured to engage the at least one driving gear to convert rotation of the at least one driving gear into the linear motion and the curvilinear motion;
• and
• a grip member configured to:
• hold the print media on the print medium stacking plate, and
• be moved linearly and curvilinearly by the moving member moving in the linear motion and the curvilinear motion, while holding the print media on the print medium stacking plate, to thereby discharge the print media and place the print media on the stacker tray.
