Abstract
A breaking switch for ink feeding channel and a printing device using the breaking switch prevents leakage of ink when a printing device is not level or not well placed. The printing device includes a case, an ink box, an ink feeding channel from the ink box, and a breaking switch for ink feeding channel. The breaking switch clamps or releases the ink feeding channel and includes a supporting base and a pressing plate. The pressing plate is rotatable between open and closed positions. When on a level working surface, the supporting leg lifts the pressing plate away from the supporting portion. When the supporting leg is free and suspended the pressing plate presses on the supporting portion and closes off the ink supply.
