Patent attributes
A recording head cartridge in which ink tanks include a removal preventing pawl which is provided at a rear surface of an ink container and engages with a tank holder, and a latch lever which is provided at a front surface of the ink container and which has a latch pawl engaging with the tank holder. The height of a rear wall and a side surface of the tank holder are set to be lower than corresponding heights of the ink tank. During removal, the container abuts the upper end of the peripheral wall of the tank holder an dis rotated about this upper end so that a part of the side surface of the container is protruded externally of the holder. Accordingly, a space required to remove the container form the tank holder is placed external of the peripheral wall of the tank holder. Thus, removal space ordinarily wasted by a conventional tank holder can be eliminated.
