摘要:
An ink jet textile printing apparatus includes a printing section having a recording head and performing printing on a recording medium by ejecting ink from the recording head, a transporting belt having an adhesive surface, and a lifting preventer disposed on an upstream side with respect to the printing section in a transporting direction in which the transporting belt is rotated. The lifting preventer includes a free roller that is provided over the recording medium adhered to and supported by the transporting belt and is movable in the transporting direction and in a direction opposite to the transporting direction.

A processor capable of performing a filter processing in a high speed is provided. A computing unit comprises a computer for performing a filter processing. Data supply to the computer is performed by an internal register configured by a flip-flop. Data read from the internal register is outputted to a shift register and the data is supplied to the computer per cycle. And, the computing unit comprises a mechanism for changing a filter computing direction according to a motion vector, thereby preventing performance lowering due to branched command by performing a horizontal filtering and a vertical filtering by a same command.

The present invention provides a functional block that executes video coding and video decoding based on H.264/AVC. The functional block includes two moving picture processing units, and a memory unit that stores therein data related to the results of processing of first plural macroblocks arranged within one row of one picture by the first moving picture processing unit. Data related to the results of processing of plural adjacent macroblocks, which are selected from the data stored in the memory unit, are transferred to the second moving picture processing unit. The second moving picture processing unit performs processing of one macroblock of second plural macroblocks arranged in the following row, using the transferred data.

A CODEC compresses and encodes a motion picture captured at a high speed of 240 fps frame rate in MPEG format. The CODEC divides pictures in each frame into I pictures and the main frame P pictures and the other sub frame P pictures. In encoding P pictures of the main frame, the CODEC uses I pictures that are adjacent on the time axis or P pictures of other main frames as a reference picture. With a playback device, etc., of its motion picture playback performance of 60 fps, to perform an actual speed playback with the playback time being equal to the picture-capturing time, only the main frame alone is to be subjected to playback, in that case the decoding process of P pictures of the sub frames is not required.

An ink cartridge for mounting on an ink supply needle of a recording head is provided. An ink cartridge main body having a plurality of walls and an ink supply port disposed in a wall of said ink cartridge main body and communicating from the interior to the exterior of the ink cartridge for the flow of ink through the ink supply port are also provided. A cover is adapted to seal said ink cartridge main body and is formed with an ambient air vent in the cover which is in fluid communication with ambient air through a circuitous channel formed in the cover. A second air vent is also formed in the cover and is also in fluid communication with the circuitous channel. The interior of the ink cartridge main body is thus placed in fluid communication with ambient air through the circuitous channel while preventing any ink contained in the ink tank main body from evaporating.

An ink jet type recording apparatus comprises a recording head of ink jet type for jetting ink droplets from a nozzle to form a dot pattern on a recording medium and a cleaning unit which is moved in and out of the path of movement of the recording head when required, and made up of a spatula-shaped elastic blade member and a water-absorbing rubbing member bonded to the member. In the case where the nozzle surface of the recording head is to be cleaned with the rubbing member, the cleaning operation is carried out with the rubbing member wetted with ink. In cleaning the nozzle surface with the blade member, the latter is abutted against the recording head as it is.

An ink tank cartridge for an ink-jet type recording apparatus being removably mounted onto an ink supply needle of a recording body is provided. The ink tank cartridge is provided with a first chamber for storing ink and a second chamber for storing a porous member having ink impregnated therein. The second chamber communicates with the first chamber through a passageway formed within the cartridge between the first and second chambers. An ink supply port extends through and projects from a wall of the second chamber. The ink supply port supplies inks to the ink-jet recording apparatus through said porous member. A funnel-shaped packing member is provided within the ink supply port. The packing member is formed with a hole therethrough having a wide end and a narrow end and is dimensioned to receive the ink supply needle and to resiliently abutt against an outer periphery of the ink supply needle. The packing member is formed for preventing the flow of ink through the ink supply port other than through the ink supply needle when the needle is positioned in the ink supply port. The wide end of the hole is disposed away from the porous member.
摘要:
In a recording apparatus with an ink jet print head which forms dots on a recording sheet by ink jets shot from an array of nozzles, a microcomputer determines whether a printing defect is a light printing defect caused by paper particles and dust adhering to the nozzles or a heavy printing defect caused by the entry of air bubbles into the ink flow paths. The determination is made on the basis of intervals of operating a print recovery button mounted on a chassis of the recording apparatus. For the light printing defect, the computer puts a cap member to the front face of the nozzles of the print head and applies a negative pressure to the nozzles, thereby to reduce the amount of ink emitted from the nozzles. For the heavy printing defect, the computer increases the amount of ink.
