An ink tank suitable for use in an ink-jet recording apparatus, comprises a closed ink bladder of a flexible material, the ink bladder being formed by assembling two double-folded sheets with each other or by folding a single sheet with the peripheral matched portions of the folded sheets or sheet adhered to each other, and the larger sheet or said single sheet includes a plug member sealingly attached thereto at a position adjacent to the folded portion of the larger sheet or adjacent to the corresponding portion of said single sheet, said plug member having an ink outlet port. In an ink-jet recording apparatus comprising such a closed ink bladder of a flexible material for supplying ink to a recording head, the plug member mounted on said ink bladder includes a pair of upper and lower electrodes exposed to the ink in said ink bladder, inwardly extending ribs disposed on the opposite sides of said plug member and effective to prevent said ink bladder from completely collapsing, and detection means for sensing a change in electrical resistance between said electrodes to detect the residual amount of ink within said ink bladder when a gas enclosed in said ink bladder reaches between said ribs.
摘要:
An ink jet recording apparatus supplying ink from a main tank to a head via a sub tank. The sub tank has two flow paths communicating with the main tank, an atmosphere communicating part, and a liquid exit part to the head. The liquid in the sub tank is maintained at a constant liquid level position by selecting, between the two flow paths, the flow path having a lower flow path resistance. Thus, the ink jet recording apparatus can store a predetermined amount of liquid stably in the sub tank. The ink jet recording apparatus and the liquid supply apparatus are capable, even when the main tank is detached or the ink therein is exhausted, of continuing the recording for a predetermined time or number of sheets, utilizing the ink in the sub tank.
摘要:
A liquid discharge recording head comprising a recording head main body provided with a plurality of liquid flow paths communicated with a plurality of discharge ports for discharging liquid, respectively, and energy generating means for generating energy utilized for discharging the liquid filled in the liquid flow paths from the discharge ports, and an orifice plate provided with a discharge port array having the plurality of discharge ports aligned in one straight line, and bonded to the front face of the recording head main body having openings of the plurality of discharge ports formed therefor, wherein the orifice plate is provided with the extended portion in the alignment direction of the discharge port array or in the direction orthogonal to the alignment direction, being extended more than the width of the front face of the recording head main body, and the extended portion is fixed to the adjacent face of the front face of the recording head main body.
摘要:
An ink jet recording apparatus means ink is discharged from a recording head onto a recording material for recording. The ink jet recording apparatus has a cap for closing an ink discharge portion of the recording head, and a device for indicating that the ink discharge portion has been closed with the cap.

A scanner head cartridge, which can be mounted exchangeably with an ink head cartridge on a carriage capable of moving the ink head cartridge of an information processing apparatus for recording on a recording medium, includes a lower case containing therein optical parts required for reading, an upper case structured to be coupled with the lower case for covering the open face of the lower case and guiding means arranged on the upper surface of the upper case for positioning when being inserted into the carriage. With the structure thus arranged, it is possible to mount the scanner head cartridge on the carriage by a simple mounting operation with a highly precise positioning simultaneously.
摘要:
An ink jet recording method including the steps of providing a movable carriage having a sensor and which carries a recording head, as well as a plurality of flags in a movable range of the carriage. The method further includes the steps of determining a position of the carriage on a basis of an output of the sensor responsive to the flags, effecting a movement of the carriage through a predetermined distance on the basis of the output of the sensor, and effecting a predetermined operation on the basis of an output of the sensor.
摘要:
In an ink jet recording apparatus for performing recording by discharging ink from a recorder a recording medium, there is provided a rubbing member which is caused to be slidably in contact with the discharging port surface of the recorder for each of the predetermined operations in order to remove ink droplets, water droplets, dust, and other impurities as well as ink films created by the adhering ink, which cause defective ink discharging, hence enabling a more reliable cleaning operation to attain a higher printing quality.
