Abstract: An apparatus for measuring the amount of ink remaining in an ink tank using a sensing module and a detecting circuit is disclosed. The sensing module comprises a fixed device connected to the casing of the ink tank and a movable device connected to the bag. As the ink is ejected, the volume of the bag increases so that the movable device moves along with the bag. The detecting circuit, coupled with the sensing module, generates a corresponding detecting signal according to the variation in the relative position of the movable device and the fixed device, and the measurement of the ink amount is thus obtained.

Abstract: An ink container having an ink reservoir for storing ink, a cover set above the ink reservoir for forming an ink adjusting room with a top portion of the ink reservoir, an ink outlet for providing ink within the ink reservoir, and an elastic deformation device set within the ink reservoir. The elastic deformation device is connected to the gap of the ink reservoir to accept external air into the elastic deformation device. When a pressure within the ink reservoir is lower than a pressure of external air, the external air flowing into the elastic deformation device of the ink container causes the elastic deformation device to expand. When the pressure within the ink reservoir is higher than the pressure of the external air, the elastic deformation device shrinks to have an outwardly overlapping wall with a folding shape in order to balance the pressure of the external air with the pressure of the ink reservoir.

Abstract: A microinjector head with a driving circuit and the manufacturing method of the microinjector head are shown. The microinjector head uses a bubble as a virtual valve to eject fluid. The microinjector head has a manifold, chambers, a pair of first and second bubble generators, orifices, and a driving circuit. The driving circuit is used to control the pair of first and second bubble generating devices and eject fluid inside the corresponding chamber from the corresponding orifice. In addition, because the driving circuit and the bubble generators are integrated on a single substrate, the number of manufacturing processes is reduced and the circuit devices and connecting circuits of the. microinjector array are fewer.
