摘要： An ink jet recording apparatus includes: a timer (26) that outputs a signal upon measurement of a predetermined time that is longer than a predetermined cycle during a period for which recording heads (8, 9) are released from a cap member (uncapped period) after a print command has been outputted; and a flushing control means (27) that control to move the recording heads (8, 9) to an ink receiving means so that the recording heads jet ink droplets, in response to the signal from the timer (26), and to reset the timer (26). If the predetermined time set to the timer (26) is up during uncapped period, the flushing control means (27) flushes a maximum number of ink droplets, and upon end of a single round of printing, the flushing control means (27) flushes a number of ink droplets corresponding to a time measured by the timer (26).

摘要： A tube pump for an ink jet printer includes a driving wheel that is selectively driven in a forward or reverse direction in accordance with the rotation of a drive source. The driving wheel contains two slots that extend symmetrically and radially from the center of the driving wheel. The pump also includes two rollers that are coupled to the drive wheel via roller shafts respectively extending from a radial center of the rollers into the slots. A pressing piece is also provided that forces the shafts into the radially outermost end of the slots to press a tube of the tube pump when said drive wheel rotates in reverse and forces the shafts into the radially innermost end of the slots to not press the tube when said drive wheel rotates in the forward direction. In an alternative arrangement, the tube pump contains a pump chamber, and a tube having an .alpha.-like-shaped loop portion is inserted into and disposed along the inner wall of the pump chamber. A driving wheel train is provided, rotated around a shaft of the pump chamber, and has a single roller that cooperates with the inner wall of the pump chamber to press the tube. Also, a guide slot is formed in the driving wheel train to transfer the roller between a tube pressurizing state and a tube nonpressurizing state based on the rotation of the driving wheel train.

摘要： Ink is sucked in a first amount from recording heads by applying negative pressure of suction pumps to the recording heads in a state in which communication between the recording heads and the atmosphere is cut off by sealing the recording heads by means of caps. The ink in the caps is then discharged by causing negative pressure of the suction pumps to act in a state in which the caps are made to communicate with the atmosphere, and then wiping is effected by a wiping blade.

摘要： An ink tank cartridge is provided removably mountable onto an ink supply needle of the ink-jet type recording apparatus body. The cartridge has a housing provided with an ink supply port extending through and projecting from a wall of the housing and into the chamber of the housing. A porous member having ink impregnated thereon is positioned inside the chamber of the housing abutting against the ink supply port. A filter is mounted on the inner end opening of the ink supply port. The ink tank cartridge is further provided with a packing member for resiliently abutting against the outer periphery of the ink supply needle and is positioned adjacent one end of the ink supply port. The outer opening of the ink supply port is sealed with a sealing member through which the ink supply needle penetrates. A further porous member may be positioned in the ink supply port between the packing member and the filter to prevent a false ink end indication caused by air reaching an electrode of an ink end sensor positioned between the filter and the further porous member when the ink tank cartridge is removed from the recording apparatus.

摘要： An ink jet recording apparatus which includes a recording head communicated via an ink supply needle with an ink tank and including electrodes for detecting a remaining amount of ink and being responsive to a print signal for spouting ink drops to recording paper, a capping unit abutting against the front of said recording head for holding the nozzle openings in an airtight state, a suction pump for supplying negative pressure to the capping unit, a resistance value detection circuit for detecting electric resistance across the electrodes for detecting a remaining amount of ink, a reference value storage unit for storing a resistance value across the electrodes relative to the remaining amount of ink in the ink tank, a resistance value comparison unit for comparing the resistance across the electrodes with the reference value, and a pump control unit responsive to the resistance value comparison result for controlling a pulse motor driving the suction pump. The resistance value detected by the resistance value detection circuit is compared with the reference value stored in the reference value storage unit to determine whether or not an ink tank is mounted, remounted, how much ink is in the ink tank, etc. Based on the determination result, the motor is controlled by the pump control unit for selecting the suction mode of ink from the recording head.

摘要： An ink jet recording apparatus having a sheet forward roller 8 and a pump unit 11 connected to a single drive motor 7, and a drive force is transmitted to the pump unit 11 through time lag mechanisms 33-34 that cause a time lag at the time of switching rotational directions. Sheet feeding/discharging operation and ink sucking operation are performed with the single drive motor by taking advantage of a timing at which there are no load fluctuations accompanied by the switching operation, without requiring any switching mechanism.

摘要： First and second cap members seal nozzle openings of first and second ink jet recording heads and are disposed on a side of a slider facing the nozzle openings. The slider is rotatably supported at the center portion in the longitudinal direction by a supporting member which is rotatable about a rotation shaft elongated in a direction perpendicular to the moving direction of the carriage, and which is vertically movable in accordance with the movement of the carriage. When the carriage is moved, the slider swings about the shaft in a manner similar to a seesaw, whereby the two cap members are sequentially fitted into the recording heads.
