Pipe 15 is connected to pump 17 with hollow needle 87.When just print cartridge 91 is installed in the print cartridge mounting portion 85, driving pump 17 forcing to be sent in the corresponding injector head 2 from the China ink of corresponding black memory 93 in cleaning operation etc.Driving pump 17 not in any printing, and the China ink in memory 93 flows to injector head 2 by the ink passage that is formed in the pump 17.
On the upper end of pump 17, be provided with Y tube 18 so that come the China ink of self-pumping 17 to be divided into two-way.Flexible pipe 19 is connected with Y tube 18 with 20.These pipes 19 are connected with the pipe joint 11 of two injector heads 2 that belong to different injector head group 3a and 3b respectively with 20.Therefore, China ink is by pump 17 and manage 19 and supply to two injector heads 2 that belong to different injector head group 3a and 3b with 20 from a print cartridge 91.
The end that Y tube 21 is opposite with hollow needle 88 with pipe 16 is connected.Flexible pipe 22 is connected with Y tube 21 with 23.These pipes 22 and 23 be connected to the corresponding block 61 and 62 of two injector heads 2 that belong to different injector head group 3a and 3b on.Therefore, the useless China ink that is drained in the block 61 and 62 flows to useless black memory 94 by managing 22 and 23.
To the maintenance unit 60 that be used for injector head 2 is carried out attended operation be described below.Maintenance unit 60 comprises: with each corresponding block 61 and the wiper 63 of respective spray 2 that belongs to injector head group 3a and 3b; Travel mechanism 70, be used to make block 61 and wiper 63 and block a shot 62 and wiper 64 move along opposite directions with respect to main scanning direction; And pallet 69, it carrying thereon block a shot 61 and 62, wiper 63 and 64 and travel mechanism 70.
In pallet 69, be formed with rectangular through- hole 68a and 68b with relative with 3b with corresponding injector head group 3a.Its size of among through hole 68a and the 68b each can comprise all jet faces 4 of four corresponding one injector heads 2 that belong to injector head group 3a and 3b.
As shown in Figure 2, each in the capping 61 and 62 by two springs 67 from following support.When annular protuberance 66 contacted with jet face 4, spring 67 absorbed and impacts.This has prevented that jet face 4 is impaired.
When printing, as shown in Figure 1, in plane wiper 63 or 64 be arranged on block 61 or 62 and corresponding injector head 2 between.When block 61 and 62 does not also descend under the effect of block elevation control mechanism therefor, this will be described below, and wiper 63 and 64 upper end are in the height place substantially the same with 61 and 62 the base 65 of blocking a shot.For example make by rubber or resin by elastomeric material in the wiper 63 and 64 each.
As for an injector head 2, block and wiper are arranged to a row along main scanning direction with being adjacent to each other.With respect to sub scanning direction, block is arranged on the position identical with injector head 2 with wiper.Corresponding with among injector head group 3a and the 3b each four wipers 63 or 64 are spaced from each other with respect to sub scanning direction and are arranged to a row.The whole width of each in the wiper 63 and 64 equates basically with the whole width of the jet face 4 of each injector head 2.Therefore, even four injector heads 2 of each in belonging to injector head group 3a and 3b eject different colours when China ink, also can prevent these China inks because wiping and colour mixture.
As illustrated in fig. 1 and 2, travel mechanism 70 comprises: two horizontally extending gripper shoes 71 and 72; The endless-belt 73 that clips with respect to sub scanning direction by gripper shoe 71 and 72; And the pair of rolls 74 and 75 that is arranged on the injector head group 3a and the 3b outside with respect to main scanning direction.
Gripper shoe 71 is being carried block 61 and the wiper 63 corresponding with the respective spray that belongs to injector head group 3a 2 thereon.Block 61 and wiper 63 are adjacent to each other with respect to main scanning direction, and are arranged on the position identical with the respective spray of injector head group 3b 2.Gripper shoe 72 is being carried block 62 and the wiper 64 corresponding with the respective spray that belongs to injector head group 3b 2 thereon.Block 62 and wiper 64 are adjacent to each other with respect to main scanning direction, and are arranged on the position identical with the respective spray of injector head group 3a 2.
Gripper shoe 71 is connected with belt 73 parts with each the inner with respect to sub scanning direction of 72.More particularly, gripper shoe 71 is connected with the top of belt 73, and gripper shoe 72 is connected with the bottom of belt 73.Therefore, when belt 73 operations, gripper shoe 71 and 72 is along moving with respect to the main scanning direction opposite directions.
As shown in Figure 1, each all is located on the pallet 69 to clip through hole 68a and 68b with respect to sub scanning direction along four guide rail 68c that main scanning direction extends.Two guide rail 68c are assemblied in the groove of gripper shoe 71 with respect to the place, two ends of sub scanning direction slidably above in Fig. 1.This relation is equally applicable to remain two guide rail 68c and gripper shoe 72.
When unshowned drive motor roller 74 rotated counterclockwise in Fig. 2, two gripper shoes 71 and 72 moved with close mutually.Gripper shoe 71 with 72 thus from as shown in Figure 1 move to each block there and its relative closure position of jet face 4 of injector head 2 accordingly without any jet face 4 its relative withdrawn position of block and any wiper and respective spray 2 there.When roller 74 clockwise rotated in Fig. 2, two gripper shoes 71 and 72 moved to be separated from each other.Gripper shoe 71 and 72 moves to its withdrawn position from its closure position thus.
Next the operation when safeguarding describes to maintenance unit 60 with reference to Fig. 5 A, 5B and 5C and Fig. 6 A, 6B and 6C.Maintenance comprises: cleaning operation, carry out this cleaning operation during when being installed in print cartridge 91 on the printer 1 or in the ink-jet variation; After cleaning operation, pass through the wiping operation of the jet face 4 of wiper 63 and 64 wiping injector heads 2; And printer 1 does not print in the sleep pattern that waits with the capping of the jet face 4 of block capping injector head 2 operate for a long time therein.
With reference to Fig. 5 A to 5C cleaning operation and wiping operation are described below.Before the beginning cleaning operation, make all injector heads 2 be moved upward to its maintenance position in advance, shown in Fig. 5 A from its print position.Make roller 74 in Fig. 5 A, rotate counterclockwise then so that belt 73 operations.By the operation of belt 73, the gripper shoe 71 and 72 corresponding with respective spray head group 3a and 3b in Fig. 1 respectively left and move right.Thus, make gripper shoe 71 and 72 move to its closure position from its withdrawn position.
When gripper shoe 71 and 72 is in its closure position place and injector head 2 and is in its maintenance position place, thereby driving pump 17 will be forced infeed in the corresponding injector head 2 at the China ink in the black holder 94 of print cartridge 91.Therefore, carry out cleaning operation, wherein from the nozzle 4a of injector head 2 to block 61 and 62 ink-jets.At this moment, 61 and 62 contact with the jet face 4 of each corresponding injector head 2 though block a shot, the China ink that sprays is dispersed in around the block 61 and 62 hardly, this be because of block a shot 61 and 62 and jet face 4 between distance less relatively.The China ink that is contained in the block 61 and 62 is drained in the useless black holder 94 of respective ink tanks 91 by managing 22 and 23.
After cleaning operation, shown in Fig. 5 B, all blocks 61 and 62 move down under the effect of unshowned block elevation control mechanism therefor, thereby make the upper end of block 61 and 62 be in the height place lower than the upper end of wiper 63 and 64.Afterwards, make all injector heads 2 be moved down into injector head 2 jet face 4 can with the height place of the last end in contact of wiper 63 and 64, thereby away from the upper end of block 61 and 62.Under this state, roller 74 clockwise rotates in Fig. 5 B so that gripper shoe 71 and 72 moves back to its withdrawn position from its closure position.During the moving of gripper shoe 71 and 72, wiper 63 contacts with 64 jet faces 4 by bending and respective spray 2, wiping attached to the China ink on each jet face 4 in cleaning operation.
After gripper shoe 71 and 72 turned back to its withdrawn position, shown in Fig. 5 C, block 61 and 62 was moved upwards up to its original height under the effect of block elevation control mechanism therefor.Therefore finished the sequence of operations that comprises cleaning operation and wiping operation.
Next with reference to Fig. 6 A to 6C the capping operation is described.Before beginning capping operation, all injector heads 2 are moved upwards up to its maintenance position from its print position in advance, as shown in Figure 6A.Roller 74 rotates counterclockwise in Fig. 6 B so that belt 73 operations then.By the operation of belt 73, make gripper shoe 71 and 72 move to its closure position from its withdrawn position.
When gripper shoe 71 and 72 had arrived its closure position, shown in Fig. 6 C, all injector heads 2 were moved down into its print position.Thus, corresponding in the jet face 4 of each injector head 2 and the block 61 and 62 forms enclosure space to prevent the China ink exsiccation in the nozzle 4a of injector head 2.
As mentioned above, in this embodiment, thereby layout injector head 2 its jet faces 4 form two rows that extend along sub scanning direction, and it is not overlapped with respect to sub scanning direction to belong to the different jet faces of arranging 4.Therefore, in zone, be provided with free space with respect to sub scanning direction and each group injector head 2 adjacency.The block 61 or 62 corresponding with the injector head 2 of each group is arranged in this space.Therefore, any special space needn't be set and be used to provide block 61 or 62.This size that has realized printer 1 reduces.
In addition because print cartridge 91 is arranged on below the block, so can effectively utilize the block below free space.This size that has realized printer 1 more effectively reduces.In addition, in the difference in height between each injector head 2 and the respective ink tanks 91 makes injector head at China ink difference appears.Therefore, the negative pressure that forms according to the difference in black injector head always is applied on the China ink in the injector head 2.This forms stable black meniscus in each nozzle 4a.Therefore, prevented that ink leakage from going out.
It is following to clip conveying mechanism 10 that print cartridge 91 is arranged on block 61 and 62.This size that has realized printer 1 further reduces.
The inlet face that leads to print cartridge 91 and paper feeding cassette 81 is located at the place, front of printer 1 jointly.This help print cartridge 91 and paper feeding cassette 81 each installation, dismounting and more change jobs, and help the size of printer 1 to reduce.In addition, because paper feeding cassette 81 is arranged on below the conveying mechanism 10 to be clipped by print cartridge 91 with respect to main scanning direction, so can further reduce the size of printer 1.
In addition, in four print cartridges 91, two print cartridges 91 in the inside are arranged to injector head 2 overlapping vertically.This size that has realized printer 1 further reduces.
Because useless China ink can be abandoned when changing respective ink tanks 91, so independent big useless black holder needn't be set in printer 1.This has realized the reducing of size of printer 1 more effectively.
Because travel mechanism 60 makes block 61 and 62 move along main scanning direction and rightabout, so realized more effectively utilizing of space.
By the operation of a belt 73, can make all blocks 61 and 62 move to its closure position, and move to its withdrawn position from its closure position from its withdrawn position.This has realized the simple structure of travel mechanism 70.
In the gripper shoe 71 and 72 each carries four 61 or 62 and four wipers 63 of block or 64 thereon, thereby corresponding with among injector head group 3a and the 3b each.This makes belt 73 is set easily.
The injector head 2 that belongs to the respective spray head group 3a that is used to spray the minimum black ink of brightness and 3b is the most approaching each other with respect to sub scanning direction.Therefore, for example, even when carrying under the state of white A4 specification paper in its long limit and throughput direction A inclination, the deviation of the rum point of the black ink that ejects from those injector heads 2 is also not obvious.If be used to spray black ink each injector head group injector head with respect to sub scanning direction each other farthest, then this has increased between black ink that ejects from an injector head and the black ink that ejects from another injector head the time-related difference at the bump paper.Therefore, the deviation of the rum point of black ink becomes obvious easily.On the contrary in this embodiment, because it is the most approaching each other to be used to spray two injector heads 2 of black ink, so reduced striking the time-related difference of paper.This has reduced the deviation of unconspicuous rum point.
The injector head 2 that belongs to the respective spray head group 3a that is used to spray the highest yellow ink of brightness and 3b with respect to sub scanning direction each other at a distance of farthest.Yellow ink is difficult to attract attention.Therefore, even some deviations occur carrying on the rum point that causes in yellow ink owing to the inclination of paper, this rum point deviation also is difficult to attract attention on the whole.
In the modification of using the black paper, the above-mentioned injector head 2 that is used for spraying at first black ink can spray white ink.That is to say, can on paper, be injected in the China ink of the most remarkable color from the China ink that all injector heads 2 eject with respect to sub scanning direction each other at a distance of nearest injector head 2.Also have, in this modification, the injector head that is used on the black paper, spraying the China ink of remarkable color and is white ink with respect to sub scanning direction each other at a distance of recently.Therefore, even when paper tilts to carry with respect to throughput direction A, as above-mentioned embodiment, the deviation of white ink rum point also is difficult to significantly.In addition, the above-mentioned injector head 2 that is used for spraying at first yellow ink can spray the grey China ink.That is to say, can on paper, be injected in the China ink of the least obvious color from the China ink that all injector heads 2 eject with respect to sub scanning direction each other at a distance of injector head 2 farthest.Also have in this case, be used for the black paper spray the least obvious China ink of color be the injector head 2 of grey China ink with respect to sub scanning direction each other at a distance of farthest.Therefore, even when paper tilts to carry with respect to throughput direction A, the deviation of grey China ink rum point is also more difficult significantly, as above-mentioned embodiment.
Next with reference to Fig. 7 the ink-jet printer 201 according to second embodiment of the invention is described.
