Inkjet printing apparatus
An inkjet printing apparatus includes a print head configured to perform print operation, the print head having an ejection opening surface on which a plurality of ejection openings for ejecting ink are arrayed along an array direction, and a moving unit configured to move the print head between a printing position, at which the print operation is performed, and a standby position, at which the print operation is not performed. The moving unit moves the print head between the printing position and the standby position by performing rotational movement, in which the print head is rotated around a rotation axis that is parallel to the array direction, and linear movement, in which the print head is moved linearly.

6. The inkjet printing apparatus according to claim 1 , wherein the print head performs the print operation by relatively moving the print head and a print medium in a first direction, and
wherein the rotation axis is orthogonal to the first direction.
7. The inkjet printing apparatus according to claim 1 , wherein the print head ejects ink based on print data to perform the print operation.
8. An inkjet printing apparatus comprising:

a moving unit configured to move the print head between a printing position, at which the print operation is performed, and a standby position, at which the print operation is not performed,
wherein the moving unit moves the print head between the printing position and the standby position by performing (1) first movement, in which the print head is rotated around a rotation axis that is parallel to the ejection opening surface, and (2) second movement, in which the rotation axis is moved in a gravitational direction.
9. The inkjet printing apparatus according to claim 8 , wherein the print head performs the print operation by relatively moving the print head and a print medium in a first direction, and
wherein the rotation axis is orthogonal to the first direction.
10. The inkjet printing apparatus according to claim 8 , wherein the moving unit performs the first movement and the second movement by a single driving source.
11. The inkjet printing apparatus according to claim 8 , wherein, in a case in which the print head is at the standby position, the ejection opening surface is closer to a horizontal posture than in a case in which the print head is at the printing position.
12. The inkjet printing apparatus according to claim 11 , wherein the ejection opening surface is kept at an angle greater than 0 degrees and less than 90 degrees with respect to a horizontal direction in a case in which the print head is at the printing position, and
wherein the ejection opening surface is kept substantially horizontal in a case in which the print head is at the standby position.
13. The inkjet printing apparatus according to claim 12 , wherein the ejection opening surface is kept at about 45 degrees with respect to the horizontal direction in a case in which the print head is at the printing position.
14. The inkjet printing apparatus according to claim 8 , wherein the print head is a full line type print head, of which the ejection openings are arrayed in an area corresponding to a width of a print medium.
15. The inkjet printing apparatus according to claim 8 , wherein the moving unit moves the print head by simultaneously performing the first movement and the second movement.
