Abstract: A print head can suppress contamination due to ink at the time of being mounted on a printing apparatus and/or after being detached from the printing apparatus. For this purpose, a positioning pin longer than a needle is provided in a joint unit of the print head, and the joint unit includes a shutter which closes an opening on a supply side and an opening on a collection side when the print head is detached.

Abstract: 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.

Abstract: 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.

Abstract: An inkjet printing apparatus includes a stacking unit, a print head having an ejection opening surface located vertically above the stacking unit, and a platen that supports a back side of a print medium at an angle greater than 40° and less than 50° with respect to a horizontal direction. A discharging unit is located vertically above the print head, and a print medium subjected to printing by the print head is discharged onto the discharging unit. A conveying unit conveys a print medium, subjected to printing by the print head, vertically upward toward the discharging unit. In addition, 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 a direction of gravity in a case in which the inkjet printing apparatus is in a standby state.

Abstract: The present invention provides a print head which suppresses contamination due to ink at the time of being mounted on a printing apparatus and/or after being detached from the printing apparatus, and a printing apparatus which prints using the print head. For this purpose, a positioning pin 98 longer than a needle 112 is provided in a joint unit 91 of a print head 8, and the joint unit 91 includes a shutter 93 which closes an opening on a supply side and an opening on a collection side when the print head 8 is detached.

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

Abstract: A waste pack for a printer includes a port, a sealing member configured to seal the port, and an urging member. When the waste pack is attached to the printer, a discharge port of the printer pushes the sealing member and enters the waste pack through the port. When the waste pack is detached, the sealing member urged by the urging member closes the port.
