The specific embodiment
Followingly describe with reference to the embodiment of accompanying drawing to the utility model.Fig. 1 is the schematic isometric of the line ink-jet printer of the printing equipment that relates to of an embodiment as the utility model, and Fig. 2 is the diagrammatic side view of observing the line ink-jet printer of Fig. 1 from the S direction.
The printing equipment that this embodiment relates to (below be called " printer ") the 1st to the ink-jet printer that prints as the ink of the atomizing of liquids shapes such as printing sheets of recording medium, is the high-throughput ink-jet printer that adopts the so-called line head mode of the record head that used its length to cover paper width (below be called " line head ") 12.
This printer 1 is owing to use line head 12; Ink-jet head is moved back and forth at paper width direction; And use not shown conveying mechanism to move to throughput direction as one of recording medium routine recording paper, on pressing plate 63 carry on one side from line head 12 injection ink executive loggings on one side.That is, feeding recordable paper is opened between line head 12 and pressing plate 63.And, carry the recording paper write down and to row's paper disc 42 row's paper.Distance between line head 12 and the pressing plate 63 is lacked more difficult the atomizing more, but is set at about 1.5mm usually.At this line head 12, for example the ink nozzle of all kinds (not shown) of yellow, fuchsin, cyan, black etc. on the throughput direction of recording paper by the setting of staggering of each color.
Each ink nozzle (not shown), also supply with inks to line head 12 via auxiliary ink box 32,34 and not shown auxiliary ink box through ink supply conduit (not shown) from the main ink cartridge 22,24,26,28 of usefulness of all kinds.
And,, on recording paper, form small inkspot through spraying the ink droplet of necessary amount from each ink injection nozzle.Carry out like this through each color, only make the recording paper single pass, record is accomplished.
For main ink cartridge, 22 accommodate cyan ink, 24 accommodate carmine ink, 26 and accommodate the ink that yellow ink, 28 accommodates black.The yellow ink of main ink cartridge 26 is carried to auxiliary ink box 34 via the check-valves 62 of S side.Equally, the black ink of main ink cartridge 28 is carried to auxiliary ink box 32 via the check-valves 62 of S side equally.In addition, though check-valves 62 with yellow with putting down in writing with the black chest of assembly of using foreign currency, be provided with the check-valves of usefulness of all kinds therein.
At main ink cartridge 22,24, be arranged in the auxiliary ink box of using with the check-valves 62 and the not shown cyan of S side opposition side, the auxiliary ink box that carmetta is used also is the formation identical with the formation of above-mentioned yellow and black.
The black ink that is stored in auxiliary ink box 32 is supplied to line head 12 from auxiliary ink box 32 through pump 52, and is sprayed to recording paper with injection nozzle from black.
In addition, the black ink that is not sprayed is reduced to auxiliary ink box 32 via pump 52.That is, a black ink part of utilizing the driving of pump 52 to see off from auxiliary ink box 32 is sprayed, the remaining auxiliary ink box 32 of getting back to once more.This is in order to utilize but line head 12 and make it to circulate of ink liquid cooling.
And, utilize pump 52, can be under the situation of the pipe that has used the thin and ink transfusion usefulness that flexibility is high as ink flow path, it is bad to prevent that flow resistance when ink flows in pipe from becoming the supply injection untimely, that be unable to catch up with of the ink that causes greatly.
As the mechanism of pump 52, use technique known to get final product, but in this embodiment, use the pipe pump.For pump 52; On motor, possesses rotary encoder 64; This motor is to drive for the internal circulating load of controlling the ink between auxiliary ink box and the line head 12; Signal according to exporting from rotary encoder 64 is controlled the rotation amount of motor, and then is controlled at the amount of the ink that flows in the pipe.
