1. Printing apparatus comprising a movable cartridge carrier and with a locking-and-ejection mechanism, wherein the cartridge carrier has a cavity for insertion of an ink cartridge in an interior of the cavity, said locking-and-ejection mechanism being attached to a side part of said cartridge carrier at an exterior of said cavity; the locking-and-ejection mechanism comprising a locking mechanism with a locking lever biased with a spring force by a first spring, said locking lever being tiltable around a rotation axis that is situated on said outside of the side part; the locking-and-ejection mechanism comprising an ejection mechanism with a lifting plate biased with a spring force at least by a second spring, said lifting plate being arranged so as to rotate on the outside of the side part around a rotation axis of the lifting plate that is stationary on the outside of the side part; the locking lever comprising a first locking mechanism and a second locking mechanism, said first locking mechanism locking said ink cartridge in said cavity and said second locking mechanism locking said first mechanism when said ink cartridge is in said cavity, and a manually-operable actuation button, said locking lever permitting manual actuation of said actuation button only when said cartridge carrier is in a predetermined position and, when manually actuated, said actuation button actuating said second locking mechanism to unlock said first locking mechanism and cause ejection of said ink cartridge from said cavity, and said lifting plate being rotatable to engage the locking lever upon ejection of the ink cartridge from the cavity and thereby hold the locking lever in a position that keeps said first and second locking mechanisms in the unlocked position after an ejection of an ink cartridge. |
