Inkjet printing apparatus

An inkjet printing apparatus comprising:

• a first stacking unit configured to stack first printing sheets;
• a second stacking unit located below the first stacking unit with respect to a direction of gravity, and configured to stack second printing sheets larger than the first printing sheets;
• a print head having an ejection opening surface located above the first stacking unit with respect to the direction of gravity, the print head being configured to perform printing by ejecting ink onto a printing sheet fed from one of the first stacking unit and the second stacking unit;
• a platen configured to support a back side of a printing sheet at a predetermined angle with respect to a horizontal direction;
• a first conveying path for conveying a first printing sheet of the first printing sheets from the first stacking unit to the platen;
• a second conveying path connecting a midstream of the first conveying path and the second stacking unit;
• a third conveying path for inverting a printing sheet printed by the print head, the third conveying path being connected to the first conveying path via the second conveying path;
• a discharging portion located above the print head with respect to the direction of gravity, a printing sheet printed by the print head being discharged onto the discharging portion;
• and
• a conveying unit configured to convey the printing sheet printed by the print head toward the discharging portion,
• wherein the ejection opening surface faces the platen in a case in which the inkjet printing apparatus is in a printing state, and faces downward with respect to the direction of gravity in a case in which the inkjet printing apparatus is in a standby state,
• wherein the ejection opening surface is located above a first area occupied by the second stacking unit and not above a second area occupied by the first stacking unit with respect to the direction of gravity, in both a case in which the inkjet printing apparatus is in the printing state, and a case in which the inkjet printing apparatus is in the standby state, and
• wherein a joint portion of the second conveying path and the third conveying path is located above the first area.
