At the projection 121 of balladeur train 5 and adjacent part 120 before contact, because the bias force of the first bias spring 105c is greater than the bias force of the second bias spring 105d, so under the bias force effect that is used for by the second bias spring 105d block 105a and change gear 109 being biased in the first bias spring 105c on the outside face of right side board 16a, adjacent part 120 stops at the primary importance place by contacting with a end abutment of elongated slot 119 on the side that is positioned at right side board 16a.In this state, change gear 109 keeps as shown in Figure 14 A and 110 engagements of the first input spur gear, thereby rotatablely moving of paper supply motor 106 passes to the axle drive shaft 74 of first sheet feeding-device 6 by intermediate gear 111a, 111b and ring gear 112, by paper supply motor 106 paper feed roller 6b rotated thus.
The projection 121 of adjacent part 120 by balladeur train 5 to the right (as seeing among Fig. 9) when the second place is moved, block 105a overcomes the bias force motion of the first bias spring 105c, thereby as shown in Figure 14 C, allow change gear 109 under the bias force effect of the second bias spring 105d, to shift into and 113 engagements of the second input spur gear, by intermediate gear 114a-114d and ring gear 115 rotatablely moving of paper supply motor 106 passed to the axle drive shaft 66 of second sheet feeding-device 65 thus.In Figure 14 A-14C, left and right sides is with respect to putting upside down as the left and right sides of being seen in Fig. 9.
At balladeur train 5 towards the scheduled wait position that is used for maintenance unit 101 operation (away from recording areas L right-hand member) when moving further to the right, adjacent part 120 moves to the 3rd position, and block 105a overcomes the first bias spring 105c and moves right, thereby allow change gear 109 under the bias force effect of the second bias spring 105d, to move right and 116 engagements of the 3rd input spur gear, as shown in Figure 14 B.By change gear 109 and external diameter greater than the radially outer of the major diameter finishing bevel gear cuter 117 of the external diameter of spur gear 116 in abutting connection with contacting, stop thereby change gear 109 is moved right with respect to this of spur gear 116 under the bias force effect of spring 105d.Even under the situation that balladeur train 5 moves further to the right since the 3rd position, have only block 105a to move right at adjacent part 120, and change gear 109 keeps motionless.In the 3rd position of adjacent part 120, rotatablely moving of paper supply motor 106 passes to the power importation of maintenance unit 101 by first and second finishing bevel gear cuters 117,118, be combined in scavenging pump in the maintenance unit 101 and other parts (for example being used for making the mechanism of cap portion 101a perpendicular movement) with operation.
As shown in Figure 14 B, rotatably supported by the axle that is installed on the L shaped stay bearing plate 122 with the second input spur gear, the 113 ingear intermediate gear 114a of second motivation transfer motion part 103 that is used for second sheet feeding-device 65, this L shaped stay bearing plate 122 is fixed on the right side board 16a.As shown in Figure 15, the ring gear 115 of second sheet feeding-device 65 and rotatably supported by the corresponding axis on the axle bearing plate 67c that is installed in support frame 67 (shown in Figure 12) with this ring gear 115 ingear intermediate gear 114d, support frame 67 is fixed on second lower house 21.These axles comprise horizontal shaft 123, and it supports tween drive shaft 114d rotationally and extends from axle bearing plate 67c.As shown in Figure 15, horizontal shaft 123 is also supporting pivot frame 124 pivotally, and this pivot frame 124 comprises the U-shaped part 124a that is open upwards.This pivot frame 124 can pivot around the horizontal axis of the horizontal shaft 123 that engages with U-shaped part 124a.Intermediate gear 114d is inserted between two arms of U-shaped part 124a.Pivot frame 124 is rotatably supporting intermediate gear 114b and 114c, and comprises first and second locking plates 125 and 126, and these locking plates are bent to form by being integral with pivot frame 124.First locking plate, 125 to the second locking plates 126 are near from the axis of horizontal shaft 123, and radially outward are provided with respect to intermediate gear 114c, and second locking plate 126 is farther apart from the axis of horizontal shaft 123.Axle bearing plate 67c and pivot frame 124 setover towards each other by pull spring 127, thus as seeing among Figure 15 along the anticlockwise direction pivot frame 124 of setovering.As shown in Figure 13 A and 13B, axle bearing plate 67c have be used for first locking plate 125 in abutting connection with first adjacent part 128 that contact, and L shaped stay bearing plate 122 has at its lower end and is used for second adjacent part 129 that contacts with second locking plate, 126 adjacency.Contact with the adjacency of corresponding adjacent part 128,129 by locking plate 125,126, the conter clockwise pivoting action of pivot frame 124 under the bias force effect of pull spring 127 stopped.
As shown in Figure 13 B, when first and second lower houses 20,21 were spaced from each other, intermediate gear 114a and 114b were not meshing with each other.But in this state, by first locking plate 125 and first adjacent part 128 in abutting connection with contact the conter clockwise pivoting action of pivot frame 124 under the bias force effect of pull spring 127 stopped, the tooth that prevents intermediate gear 114c thus and the horizontal component of support frame 67 occur possible bad collision and so tooth impaired.
When being arranged on first lower house 20 on second lower house 21, the intermediate gear 114b that is supported by pivot frame 124 keeps and the intermediate gear 114a engagement of being supported by first lower house 20, as shown in Figure 13 A.In this state, second locking plate 126 keeps contacting with second adjacent part, 129 adjacency, the conter clockwise pivoting action of pivot frame 124 is stopped, and prevent the excessive overload that reaches these gears that cause thus of mesh volume of the tooth of intermediate gear 114a, 114b.That is to say that second locking plate 126 and second adjacent part 129 have been guaranteed the mesh volume optimum of intermediate gear 114a, 114b.
Below will be with further reference to the block scheme of Figure 15 and the flowchart text of Figure 16: to the control system of the operation that is used for controlling image recorder 1; Be used for the rotary driving force selectivity being passed to the mode of the power transmission shifter 105 of first sheet feeding-device 6, second sheet feeding-device 65 and maintenance unit 101 with control from paper supply motor 106 (from driven wheel 108).As shown in figure 16, control system comprise the controller 130, paper edge sensor 131, the above-mentioned Y-axis coder 26 that mainly constitute by microcomputer, be used to detect the rotating speed of paper supply motor 106 rotary encoder 132, be used for the driving circuit 133 of slide-frame driven motor 25 and be used for the driving circuit of paper supply motor 106.As shown in Figure 4, paper edge sensor 131 is as being arranged on the upstream of alignment roller 22a, 22b along paper feeding seeing to A, promptly is arranged near the position the point of the first and second U-shaped rotating channels that limited by first passage and second channel member 27,34.As shown in Figure 10-12,13A and 13B, the rotary encoder 132 that is used for paper supply motor 106 is fixed on the end of alignment roller 22a and with alignment roller 22a and rotates.
Before giving image recorder 1 energising, balladeur train 5 stops at the scheduled wait position, waits in position at this, and wherein the lower surface of the header record 4 opened of nozzle contacts with cap portion 101a fluid-tight in the upper surface that is exposed to maintenance unit 101.
When controller 130 receives image recording order from outer computer in the step S2 of the diagram of circuit of Figure 17, for example in step S1, give after image recorder 1 energising, when balladeur train 5 is positioned at the holding fix place, make the predetermined step number of paper supply motor 106 operations leave header record 4 so that cap portion 101a descends.
Then, in step S3, slide-frame driven motor 25 along forwards to operation so that balladeur train 5 moves to the flush position that is positioned at directly over the black receptor 100 from holding fix.Carry out the flushing operation of header record 4 among the step S4 below.The China ink that ejects from the nozzle of header record 4 during flushing operation is stored in the black receptor part 100.
Then, control flow advances to step S6, carry out the fine motion operation of paper supply motor 106 at step S6, to allow making the change gear 109 of power transmission shifter 105 make following smooth sliding, promptly from importing spur gear 116 position engaged at the change gear 109 shown in Figure 14 B and the 3rd via importing spur gear 113 position engaged smooth sliding at the change gear 109 shown in Figure 14 C and second to importing spur gear 110 position engaged at the change gear 109 shown in Figure 14 A and first by the first bias spring 105c.The fine motion of motor 106 operation is made of one or two following circulation: motor 106 is along inverse direction step-by-step operation predetermined angular, this predetermined angular less than with the cooresponding angle of tooth pitch of spur gear 109,110,113,116; Motor 106 is along forwards to the identical predetermined angular of step-by-step operation subsequently.
After the step S5 is step S6, and it is to select the first sheet feed cassette 3A or the second sheet feed cassette 3B that step S6 is used for determining current.When selecting the first sheet feed cassette 3A, that is to say when in step S6, obtaining to judge (being) certainly, the change gear 109 of power drive 105 keeps as shown in Figure 14 A and 110 engagements of the first input spur gear, and balladeur train 5 can be owing to this engagement towards maintenance unit 101 motions.In this state, paper supply motor 106 in step S7 along inverse direction operation, with make by first motivation transfer motion part 102 paper feed roller 6b along forwards to rotation, cut paper P thereby supply with to A along paper feeding.
At paper supply motor 106 along inverse direction operating period, the uppermost paper P that cuts of this quires separates with the quires that is contained among the first sheet feed cassette 3A, and supplies to pressure nip between alignment roller 22a, 22b along paper feeding to the position of A by paper edge sensor 131.But, because not allowing to cut paper P at the hand of rotation during the reverse operating of motor 106, alignment roller 22a, 22b do not supply with the pressure nip that is passed between these rollers 22a, the 22b, so cutting paper P, this does not supply with towards header record 4.After detecting the leading edge that cuts paper P by paper edge sensor 131, the reverse operating of paper supply motor 106 continues predetermined step number, that is to say up to the pressure nip of leading edge arrival between alignment roller 22a, 22b that cuts paper P.Then, in step S8, paper supply motor 106 to the predetermined step number of operation, is supplied to predetermined recording starting position will cut paper P along forwards, the recording operation that is cutting on the paper P at this position opening entry head 4.
After the step S8 is step S9, in step S9, when balladeur train during at main scanning direction (Y-axis line direction) crank motion and when cutting paper P off and on when X-axis line direction is advanced, carry out the recording operation of header record 4, thereby form image cutting paper P to go out ink droplet from its nozzle ejection.After recording operation, in step S10, paper supply motor 106, is discharged in the recording paper receptor 10 will cut paper P to continuous handling along forwards.Under the situation that supply with at the first sheet feed cassette 3A many cut the enterprising line item operation of paper P, execution in step S7-S10 repeatedly.
When selecting the second sheet feed cassette 3B by the order that receives from outer computer, obtaining in step S6 negates to judge (denying), and control flow advances to step S11 so that balladeur train 5 moves right to importing spur gear 113 position engaged places at the change gear 109 shown in Figure 14 C and second towards maintenance unit 101.Between this moving period of balladeur train 5,, become and 113 engagements of second spur gear to guarantee change gear 109 smooth sliding according in step S12, carrying out the fine motion operation of paper supply motor 106 with reference to the described identical mode of step S5 with top.When change gear 109 and 113 engagements of second spur gear, the reverse operating of paper supply motor 106 allow by second motivation transfer motion part 103 make paper feed roller 65b along forwards to rotation, with the quires from be contained in the second sheet feed cassette 3B the uppermost paper P that cuts is supplied with to A along paper feeding.
Then, in step S13, paper supply motor 106 arrives the pressure nip of alignment roller 22a, 22b up to the leading edge of supplying with from the second sheet feed cassette 3B that cuts paper P along the inverse direction operation.That is to say that after detecting the leading edge that cuts paper P by paper edge sensor 131, the reverse operating of motor 106 continues predetermined step number.After the step S13 is step S14, and motor 106 is supplied to the booking situation starting position along forwards being scheduled to step number so that alignment roller 22a, 22b rotate to operation so that will cut paper P in step S14.Execution in step S15 is so that balladeur train 5 is moved into recording areas L, so that change gear 109 and 110 engagements of first spur gear then.For change gear 109 smooth sliding are become and 110 engagements of first spur gear, according in step S16, carrying out the fine motion operation of paper supply motor 106 with reference to step S5 and the described identical mode of S12 with top.Then, carry out and above-mentioned steps S9 and similar step S17 of S10 and S18.
As mentioned above, in the step S3 before the opening entry operation, change gear 109 is imported spur gear 113 position engaged and is displaced to it and first imports spur gear 110 position engaged with second via it from itself and the 3rd input spur gear 116 position engaged.In addition, cut the step S12 of paper P before the second sheet feed cassette 3B supplies to the booking situation starting position making, make change gear 109 be displaced to it and import spur gear 113 position engaged with second from itself and the first input spur gear, 110 position engaged.Therefore, the power transmission shifter 105 that comprises change gear 109 is convenient to optionally give first sheet feeding-device 6 or second sheet feeding-device 65 with transmission of power from paper supply motor 106 (from comprising the propulsive effort output unit of driven wheel 108).
As mentioned above, these three input spur gears 110,113 and 116 are arranged on their axial direction (main sweep or Y-axis line direction) by this declaration order, make: the first input spur gear 110 is near side plate 16a, the 3rd input spur gear 116 is near maintenance unit 101, and the second input spur gear 113 is between the first input spur gear 110 and the 3rd input spur gear 116.These three these order of placement of importing spur gear 110,113 and 116 arrange it is favourable together with change gear 109 common maintenances and first spur gear, 110 ingears, because the first sheet feed cassette 3A that is arranged on usually in first lower house 20 can be arranged to be ready to use in the relative time than weak point after receiving the printing initiation command.
These three input spur gears 110,113 and 116 layout has further advantage: comprise corresponding input spur gear 110,113 and 116 first, the second and the 3rd power drive 102,103,104 can be operably connected to the shortest power transmission path and are used for first sheet feeding-device 6, the corresponding ring gear 112 of second sheet feeding-device 65 and maintenance unit 101,115,118, thereby not only be feedway 6,65 and maintenance unit 101 in each device improved power transmission efficiency, and can make that image recorder 1 size on main scanning direction is less.
In addition, the holding fix that can be for example when changing print cartridge be positioned at (shown in Figure 3) on the right side of recording areas L by the right-hand member place that balladeur train 5 is moved to be positioned at main frame 16 carries out the cleaning operation by 101 pairs of header records 4 of maintenance unit.
Under the situation that only is provided with the first sheet feed cassette 3A, the second input spur gear 113 can remain between the first and the 3rd input spur gear 110,116, because intermediate gear 114a-114d etc. are not located at the downstream of the second input spur gear 113.In this case, can change the second input spur gear 113 by the cylindrical member that does not engage with change gear 109.
Below with reference to Figure 18-21 explanation be used to the setover bias unit of roller hold-down arm 65a of second sheet feeding-device 65 that is used for the second sheet feed cassette 3B.As top with reference to as described in Figure 10-12, the axle drive shaft 66 of second sheet feeding-device 65 is rotatably supported by axle bearing plate 67a, 67b, the 67c of support frame 67, makes that as shown in Figure 18-21 end away from the axle drive shaft 66 of ring gear 115 extends through the proximal part of roller hold-down arm 65a and the axis hole 142 of axle bearing plate 67a, 67b.
As among Figure 21 the most clearly shown in, roller hold-down arm 65a has the elongated side plate 146a of pair of parallel, 146b, they extend and are supporting paper feed roller 65b at their free end along the radial direction of axle drive shaft 66.The proximal part of side plate 146a, 146b is arranged on along between the axial direction of axle drive shaft 66 axle bearing plate 67a, the 67b opposite each other.These side plates 146a, 146b are supporting five gears of gear drive 65c, make the train of gears of these five gears be arranged between two side plate 146a, the 146b, and make that the position of this train of gears is near from side plate 146a from side plate 146b ratio.Roller hold-down arm 65a is by the bias unit biasing that with torsion spring 147 is form, make: be used for making the free end portion of roller hold-down arm 65a towards that the folded paper P travel direction that cuts that is contained in the second sheet feed cassette 3B, this roller hold-down arm 65a is setovered pivotally around axle drive shaft 66, leans against on the axle bearing plate 67a and promptly along the direction vertical with the longitudinal direction of elongated side plate 146a, 146b roller hold-down arm 65a is setovered along the axial direction of axle drive shaft 66 simultaneously.
In more detail, as shown in Figure 20 and 21, torsion spring 147 comprises: intermediate coil part 147a and from extended two end 147b of the corresponding opposed end of coiler part 147a and 147c.As shown in figure 20, torsion spring 147 is fixed on the proximal part on the side of the axle bearing plate 67a, the 67b that are positioned at support frame 67 of roller hold-down arm 65a, makes coiler part 147a be engaged on a part of axle drive shaft 66 between two elongated side plate 146a, the 146b and be positioned near the side plate 146a.An axial direction of 66 extends towards side plate 146b (on the side of axle bearing plate 67b) first end 147b from coiler part 147a along axle drive shaft, and is fixed on the retainer part 148 that forms as one with roller hold-down arm 65a.Another axial direction of 66 extends towards axle bearing plate 67a from coiler part 147a along axle drive shaft substantially for another or the second end 147c, and has the curved distal end part, this curved distal end part is as being substantially U-shaped seeing among Figure 20, and as shown in Figure 19 in the outside face press contacts of its terminal part office maintenance, thereby this roller hold-down arm 65a biasing is leaned against on the axle bearing plate 67a with axle bearing plate 67a.
Therefore, torsion spring 147 in its proximal end not only around be used for making usually paper feed roller 65b keep with at the axle drive shaft 66 of the folded end face press contacts that cuts paper P of that of second sheet feed cassette 3B biasing roller hold-down arm 65a pivotally, but also along axle drive shaft 66 axially towards the axle bearing plate 67a biasing roller hold-down arm 65a of support frame 67.Therefore, torsion spring 147 prevented roller hold-down arm 65a in its close end office along the direction vertical with its longitudinal direction promptly along the oscillating movement of the axial direction of axle drive shaft 66, therefore prevented roller hold-down arm 65a in its distal portion office the oscillating movement along the axial direction of axle drive shaft 66.Therefore, torsion spring 147 allows roller hold-down arm 65a just in time to extend along the radial direction of axle drive shaft 66, make that the longitudinal direction of roller hold-down arm 65a is just in time vertical with the axial direction of axle drive shaft 66, thereby paper feed roller 65b is just in time parallel with the rotation axis of axle drive shaft 66 at the rotation axis of the far-end of roller hold-down arm 65a, just in time supplies with along predetermined direction of the supply A (along X-axis line direction) thereby allow to cut paper P.In other words, torsion spring 147 has prevented that the rotation axis of the paper feed roller 65b that can occur generally speaking is with respect to tilting to the vertical direction of A with paper feeding, thereby paper feed roller 65b can make every to cut paper P and just in time supply along predetermined direction of the supply A, and does not cut the danger that paper P blocks.
It is to be noted that the height dimension that the second sheet feed cassette 3B has is greater than the first sheet feed cassette 3A, thereby compare the maximum height that can be contained in the quires among this second sheet feed cassette 3B with the first sheet feed cassette 3A bigger.Therefore, its length of this roller hold-down arm 65a is obviously greater than roller hold-down arm 6a, as shown in Figure 2.In this respect, rotation axis that torsion spring 147 effectively prevented the above-mentioned oscillating movement of roller hold-down arm 65a and paper feed roller 65b being set tilts with respect to the axial direction of axle drive shaft 66.
In addition, biasing roller hold-down arm 65a is so that make paper feed roller 65b keep preventing with the quires press contacts, simultaneously that roller hold-down arm 65a is simple in structure and can obtain with relatively low cost at the torsion spring 147 of the oscillating movement of its close end office.
It is very important for the folded even press contacts of the axial direction of roller 65b and paper for guaranteeing paper feed roller 65b than the mode from side plate 146b nearly (from axle bearing plate 67a than near from axle bearing plate 67b) torsion spring 147 to be set from side plate 146a according to the position that makes coiler part 147a.That is to say, the more close side plate 146b that is positioned on the axle bearing plate 67b side of five gears of gear drive 65c applies bigger power for paper feed roller 65b at its axial end portion place that is positioned on the side plate 146b side than the axial end portion place that is positioned at it on side plate 146a side thereby the weight of the 65c of this mechanism makes.Therefore, in order to ensure evenly applying power for roller 65b along its axial direction, preferably make the bias force that acts on the torsion spring 147 on the roller hold-down arm 65a big on side plate 146a (axle bearing plate 67a) side than on side plate 146b (axle bearing plate 67b) side.In this respect, in the current embodiment torsion spring 147 with respect to the location of roller hold-down arm 65a for guarantee that paper feed roller 65b is desirable for the press contacts of the uniform pressure of quires on the whole axial length of roller 65b.
As mentioned above, the roller hold-down arm 6a that is used for first sheet feeding-device 6 of the first sheet feed cassette 3A is setovered by suitable bias unit, so that make far-end maintenance and the quires press contacts among first sheet feed cassette 3As of paper feed roller 6b at roller hold-down arm 6a usually.This bias unit is preferably and torsion spring 147 similar torsion springs, it is fixed on the stay bearing plate in two axle bearing plates 63 of the proximal part of roller hold-down arm 6a and main frame 16, thereby, tilt with the rotation axis that prevents roller 6b rotation axis with respect to axle drive shaft 74 along the axial direction of axle drive shaft 74 and along the direction that the rotation axis that makes roller hold-down arm 6a around axle drive shaft 74 pivots this arm 6a that setovers.
The end face of the quires mode parallel with horizontal surface held quires though the second sheet feed cassette 3B is arranged to, but, similar with the first sheet feed cassette 3A as shown in Figure 2, box 3B can be arranged to so that the mode that the end face of quires is inclined relative to horizontal is held quires.
To describe with further reference to Figure 22 and 23 pairs of layouts in another embodiment of the invention below, this layout is used for preventing to cut paper P and blocks at the point place of U-shaped rotating channel, the same as shown in Figure 2, this point is limited by first passage member 140 and second channel member 141, and extend from the first and second sheet feed cassette 3A, 3B, be used for being supplied to the image recording section 7 that is arranged on first sheet feed cassette 3A top cutting paper P.
As shown in the enlarged drawing among Figure 22, the radius of curvature that the U-shaped rotating channel that is limited by second channel member 141 has is greater than the U-shaped rotating channel that is limited by first passage member 140, and forms at the U-shaped rotating channel rear that is limited by first passage member 140.First passage member 140 and second channel member 141 are assembled together, make first passage member 140 as along paper feeding below the downstream end at A visual angle is positioned at the downstream part of second channel member 141 and near, thereby converge in the position of the above-mentioned downstream part of second channel member 141 by first passage member 140 U-shaped rotating channel that limits and the U-shaped rotating channel that limits by second channel member 141, will cut paper P from this position and further supply with towards image recording section 7.Inwardly be provided with third channel member 82 on the part in first passage member 140 front sides, this third channel member 82 is cooperated so that cut paper P along moving to the opposite inverse direction of A with paper feeding with first passage member 140.
As shown in figure 23, first passage member 140 has two grooves 83, and these two grooves 83 are opened in the inside face that defines the U-shaped rotating channel, and by these two grooves 83 first and second couples of dummy roll 71a, 71b is exposed.The above-mentioned inside face of first passage member 140 is covered by covering member 72, and this covering member forms and is removably mounted on the first passage member 140 by synthetic resin.This covering member 72 has two holes, but these two holes allow dummy roll 71a, 71b partly to expose the pivot shaft of forbidding dummy roll 71a, 71b and expose.
