Abstract
An inking system comprising an ink vessel removably mounted on a nose portion of a wire dot matrix printer. The ink vessel is stationarily connected to a capillary path member for transferring ink reserved within the ink vessel to the rear surface of a bearing plate which is disposed at the front end of the nose portion of the printer for supporting printing ends of printing wires. The ink vessel accommodates therein an ink absorbent member such as synthetic fibers in contact with the upper end portion of the capillary path member, and reserves ink in an absorbed state in the ink absorbent member. At least one slit is formed in the lower end portion of the capillary path member such that the slit permits a group of the printing wires to extend therethrough without causing any forced contact between the respective printing wire and the lower end portion. The lower end portion wetted with the ink is forcedly contacted with the rear surface of the bearing plate by pressing means disposed within the nose portion. The ink is transferred to each of the printing wires via the bearing plate. The ink supply to the printing wires during the printing operation can be made speedily and appropriately by adjusting the bulk factor of the capillary path member within the range less than that of the ink absorbent member.
