Latest Patents

One of Takuro Ito's latest patents is an advanced ink jet printer. This design features a discharge port formed in the bottom surface of the ink tank. The ink tank is designed to communicate with a waste ink tank by connecting the discharge port to the waste ink tank in a position lower than the discharge port. A part of the connection member is openable and closable by a valve. When the connection member is opened, ink is discharged from the discharge port of the ink tank to the waste ink tank. This innovative design allows for the discharge of impurities that may accumulate on the bottom surface of the ink tank, thereby preventing clogs in the nozzle head due to these impurities.

Another notable patent is an ink supplement system. This system comprises a bottle holder unit for holding an ink bottle that stores ink and is detachably attached to it. The ink tank receives ink from the ink bottle held by the bottle holder unit. The ink bottle includes an ink supply port with a filter affixed to its back. The bottle holder unit features an ink supplement pump that suctions ink through the ink supply port of the attached ink bottle, supplementing the ink into the ink tank efficiently.
