Abstract: An ink cartridge carrier device includes a casing, having an opening and an inner chamber communicated with each other, for carrying an ink cartridge; a locking/unlocking mechanism, pivoted on the casing, such that the locking/unlocking mechanism is made to be rotatable and applies a restraining force to fix the ink cartridge into the inner chamber; a first elastic member, connected to the locking/unlocking mechanism, for providing the restraining force to actuate the locking/unlocking mechanism, so as to fix the ink cartridge into the inner chamber; a pushing mechanism, for pushing a part of the ink cartridge carried within the inner chamber out of the casing, so as to unload the ink cartridge. The device makes the ink cartridge well fixed, and enables the ink cartridge to be horizontally loaded or unloaded, which does not have the problems of unsmooth loading or unloading or getting stuck during unloading or loading.

Abstract: A tuning element having a second inclined plane interacts with a pushing element having a first inclined plane to accomplish adjusting the position of a printhead. The tuning element rotates relative to a printhead carrier and produces displacement in a second direction and the second inclined plane of the tuning element then pushes the first inclined plane of the pushing element and produces displacement in a first direction in a linear way corresponding to the rotation of the tuning element. Meanwhile, the printhead closely in contact with the pushing element also produces displacement in the first direction so that the tuning apparatus is endowed with highly accurate and linear adjustability.
