Abstract
An inkjet printing apparatus is provided capable of attaching and detaching of a print head with a mechanism that is easily operable and simple, while preventing an erroneous operation. For the purpose, it is configured so that the press/release for the print head is possible along with movement of the joint member. Further, when the joint member is connected, the connection of the joint member is performed after pressing the print head, and when the connection of the joint member is released, the pressure on the print head is released after releasing the connection of the joint member.

An inkjet printing apparatus comprising:
- a support unit configured to detachably support a print head configured to eject ink;
- a tank configured to store ink to be supplied to the print head;
- a driving source;
- a joint unit that is (1) connectable with the print head for supplying the ink from the tank to the print head and (2) movable by the driving source;
- a pressing unit configured to press the print head against the support unit;
- and
- a release unit configured to release pressure of the pressing unit in accordance with movement of the joint unit,
- wherein the joint unit is movable to (1) a first position where the joint unit is connected with the print head and the print head is pressed against the support unit, (2) a second position where the joint unit is not connected with the print head and the print head is pressed against the support unit, and (3) a third position where the joint unit is not connected with the print head and the print head is not pressed against the support unit, and
- wherein the release unit is configured to release pressure of the pressing unit by performing sliding movement between the pressing unit and the print head.
