Abstract: A recovery mechanism for ink ejection recovery of an ink jet device includes a wiping member for wiping a surface having an ink ejection outlet by relative movement between the wiping member and the surface; and a rubbing member for rubbing the wiping member by relative movement therebetween, the rubbing member being heated at a predetermined temperature.

Abstract: A black ink cartridge is mounted on a carriage capable of scanning along a guide shaft, and when a projection of the carriage rides on a sensor within the scanning range of the carriage, the weight of the black ink cartridge is detected.

Abstract: First and second guide means are provided to both a movable member which moves together with a vibration member, which is in press contact with a rail-shaped stator, and the rail-shaped stator. The first and second guide means have different functions: the first guide means restricts the degree of freedom of the movable member, and the second guide means receives a total compression counterforce of the vibration member.

Abstract: An ink jet recording apparatus which has at least one ink jet recording head to perform recording on a recording medium held on a rotary drum by discharging liquid ink from discharging nozzles, comprises a receptor, arranged on the rotary drum at a position which does not overlap with a position at which a recording medium is placed, for receiving ink droplets discharged by the ink jet recording head not for recording.

Abstract: An ink-jet recording apparatus capable of efficiently performing a pressurization recovery operation on a recording head without causing clogging due to dust particles. An ink supply system for supplying ink to the head includes an ink container with an air space defined above the ink surface, and a pump for pressurizing air within the air space, which pump is arranged to connect the air space with either the pressure side of the pump or the atmosphere. In one embodiment, the ink container compriss a main ink tank, and an auxiliary ink tank, having the air space, provided between the head and the main ink tank. The main ink tank is controlled to maintain a predetermined pressure head of ink therein, and the auxiliary ink tank is positioned such that the auxiliary ink tank can have, under atmospheric pressure, substantially the same pressure head as the main ink tank. In another embodiment, a removable ink cartridge, serving as the ink container, is divided into small and large ink chambers.

Abstract: A planar auxiliary supporting member for supporting an elastic member for generating a vibration is arranged. The elastic member contacts a rail-shaped stationary member, and moves along the stationary member. The rigidity of the supporting member is set to be low, so that the elastic member as a stator stably moves along the stationary member.
