Abstract: An inkjet printing apparatus includes an ink tank that contains an ink to be supplied to a printing head that ejects the ink, the ink being injected from an ink bottle. The inkjet printing apparatus further includes an injection assistance member including a first passage and a second passage. The first passage is defined by a first upper end portion opening toward the outside of the ink tank and a first lower end portion opening toward the inside of the ink tank. The second passage is defined by a second upper end portion opening toward the outside of the ink tank and projecting upward less than the first upper end portion and a second lower end portion opening toward the inside of the ink tank and larger than the first lower end portion in terms of a distance from the bottom surface of the ink tank.

Abstract: A printing apparatus comprises a main body, an operation panel configured to pivot about a pivot shaft, a stopper that has one end pivotably connected to the operation panel, and has a cam face on a surface thereof; a guide member that is provided on the main body and is configured to guide the stopper such that the stopper is slidable in a longitudinal direction of the stopper; and a pressing member that has a contact portion that comes into contact with the cam face, wherein the cam face has a plurality of divided cam faces that are provided in a shorter direction of the stopper, and the contact portion of the pressing member has a width that spans the plurality of divided cam faces in the shorter direction of the stopper.

Abstract: An inkjet printing apparatus comprises a carriage, on which a printhead is mounted, configured to move, a lever member configured to be rotatable about a rotating shaft and to be engageable with an engaging portion of the carriage, and a cam mechanism configured to have first and second locked states in which the lever member engages with the engaging portion of the carriage. The first locked state restricts a rotation of the lever member so as not to release an engagement with the engaging portion, and the second locked state allows the rotation of the lever member so as to release the engagement with the engaging portion.

Abstract: A printing apparatus comprises a main body, an operation panel configured to pivot about a pivot shaft relative to the main body, a stopper that has one end pivotably connected to the operation panel, and has a cam face on a surface thereof, a guide member that is provided on the main body, has a first guide face and a second guide face, and is configured to guide the stopper such that the stopper is slidable in a longitudinal direction, a first pressing member configured to press the stopper against the first guide face while being in contact with the cam face of the stopper, and a second pressing member configured to come into contact with a face of the stopper different from the cam face, and press the stopper against the second guide face.
