Stacker apparatus and printing apparatus

A printing apparatus, characterized in that it comprises

• a printing station for printing a sheet-like medium (20) and discharging the sheet-like medium (20) from one of two or more medium exits (4A to 4F) disposed in upward and downward directions, and
• a stacker station (2) including a plurality of trays (7A to 7F) for receiving sheet-like media (20) discharged from said two or more medium exits (4A to 4F) of said printing station separately and individually for said medium exits (4) in a stacked state, that
• in said stacker station (2), between two upper and lower medium exits (4C, 4D) included in said two or more medium exits (4A to 4F), a tray holder (8C) on which the upper side tray (7C) for receiving the sheet-like media (20) discharged from the upper side medium exit (4C) of the two upper and lower medium exits (4C, 4D) in a stacked state can be removably and securely held is disposed, and that
• said tray holder (8C) is selectively changed over to one of
• a first state wherein said tray holder (8C) securely holds said upper side tray (7C) when said upper side tray (7C) is mounted thereon and
• a second state wherein said tray holder (8C) releases said upper side tray (7C) and operates integrally with the lower side tray (7D) provided for receiving the sheet-like media (20) discharged from the lower side medium exit (4D) of said two upper and lower medium exits (4C, 4D) in a stacked state to function as part of a tray (7) for receiving the sheet-like media (20) from the upper side medium exit (4C) in a stacked state together with said lower side tray (7D).
