Claims

[Claims for Utility Model Registration] Cleaner is jetted from a cleaner jet nozzle facing the ink nozzle of the printer head, and the ink in the ink nozzle is returned to the ink reservoir, and the end of the ink nozzle mouth is cleaned by a rotating brush. This ink nozzle cleaning device comprises: a rotating brush with a partially missing brush portion; a cleaner injection nozzle; a pump for feeding cleaner thereto; the rotating brush and the pump. A motor for driving the rotary brush through a gear mechanism, and a stopper for stopping the rotary brush at a position where the missing part of the brush faces the ink nozzle. An ink nozzle cleaning device comprising a clutch mechanism that prevents rotational force from being transmitted to the rotating brush only when the brush rotates in a direction that engages the stopper.
