摘要： There is provided an inkjet printing apparatus capable of stably outputting high quality images in a configuration of feeding a print medium that is kept horizontal, performing printing by the use of a print head, and conveying the print medium vertically upward. To this purpose, a platen that supports the back side of the print medium in a position facing a printing part of the print head is located to support the print medium at an angle greater than 0° and less than 90° with respect to the horizontal direction, thereby reducing a contact pressure from roller pairs on the printed side immediately after printing.

摘要： Provided is a manually moved printing apparatus capable of suppressing deterioration in printing quality even if the printing apparatus is lifted or tilted. To provide this, a Y-direction sensor support shaft formed integrally with a downstream position detection sensor case and having a rotation axis in the direction of arrows is rotatably supported by a downstream sensor case support arm.

摘要： Provided is a manually scanned printing apparatus capable of suppressing deterioration in image quality. To provide this, a support portion of a guide roller and a support portion of a downstream position detection sensor are configured to be displaceable relative to each other in a direction substantially orthogonal to the printing surface of a print medium to be printed.

摘要： 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.
