A printing device 1 is provided with a housing 2, and a card stacker 3 is disposed above the housing 2. The card stacker 3 stores cards to be placed parallel in a laminate manner. Inside the housing 2 are stored a card rotating section 4, linear card transport path CP each disposed below the card stacker 3, printing section PR provided below the card transport path CP, various sensors, and control section. A card storage section 29 is disposed on the most downstream side of the card transport path CP. The card storage section 29 stores processed cards to overlap in a laminate manner. The card stacker 3 enables the supply number of cards to be increased, and it is possible to increase the height of the card storage section 29 by the card transport path CP positioning in the upper portion inside the housing 2. By this means, the invention provides the printing device capable of supporting large-amount discharge in response to large-amount supply of printing media while miniaturizing the device.
