Abstract
A platen support mechanism of a printer moves a platen unit of the printer. When moving the platen unit from a closed position to an open position, the platen support mechanism of the printer first moves the platen unit along a straight first path, and then moves the platen unit along a curved second path. A posture of the platen unit is held constant during this time by a six joint linkage mechanism.
