摘要： In a printing apparatus of an off-carriage type, when a pump motor (28) is rotated regularly for delivering pressurizing air to an ink cartridge, rotation thereof is converted into a linear reciprocating movement of a pressing member (39) by a cam mechanism (33) and a pressurizing operation is executed by repeating to operate to expand and contract a diaphragm (37). On the other hand, the pump motor is started to rotate inversely, a driven part (52) is rotated by a friction clutch mechanism (48), and a pressing portion (52b) of the driven part is brought into contact with a valve opening lever (55) of an atmospheric release valve (22). At this occasion, the valve opening lever is pivoted to bring a valve hole (56) into an opened state and pressurizing air is discharged to outside by bringing the atmospheric release valve into an opened state.

摘要： A circuit board (27) on an ink cartridge (9) has contact pads which are electrically conducted to a semiconductor storage element (65) mounted on the circuit board. Connector terminals on an ink jet recording apparatus are brought into relative slide contact with a surface of this circuit board, and electrically connected to the contact pads. When the connector terminals come in contact with the contact pads, the dust adhering to the connector terminals (70) is wiped and removed by step portions that are constituted by no-resist-film formation parts and that are adjacent to the contact pads. Consequently, the reliability of the electrical contact between the connector terminals and the contact pads is ensured.

摘要： An ink storage chamber (36) has an indicator formed from magnetic material. A float member (50) whose upper position is limited is housed in the ink storage chamber (36). Two magnetic-field detection system are provided at a position on the exterior of a sub-tank (3), at which the detection system can detect a magnetic flux of the indicator simultaneously, such that the longitudinal direction of the detection system is oriented vertically with a specified ink level of the sub-tank sandwiched between the detection system. On the basis of signals output from the magnetic-field detection system, it is determined whether the ink level is in any one of an excessively low ink level state, a state in which injection of ink must be started, a state in which injection of ink must be stopped, and an excessively supplied state. Thus, an ink level in the sub-tank (3) can be controlled within a specific range without involvement of an undesired increase in the number of sensors.

摘要： Liquid is sent from a liquid retainer (35) to a liquid ejection head (18) via a liquid supply line by pressurization force generated by a pressurization device that is driven by a driver. A method for cleaning a liquid ejection apparatus includes drawing the liquid from the liquid ejection head (18) through a nozzle (19) by a suction device (34); and obtaining a liquid remaining amount of the liquid retainer. The method further includes determining an operational speed of the driver in correspondence with a result of the calculation; and operating the driver at the determined operational speed when drawing the liquid by the suction device. Thus, liquid is consumed completely without being wasted.
