As shown in Figure 5, below first change gear 71 and second change gear 72, first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 parallel to each other is along arranging as another back shaft 100 and being supported so that can rotate around the axis of back shaft 100 by this back shaft 100.Back shaft 100 is parallel with back shaft 73.First travelling gear 101 is arranged to so that mesh and disengaging according to first change gear 71 position and first change gear 71 in the axial direction at the peripheral surface place of this first travelling gear 101.Second travelling gear 102 is arranged to so that mesh and disengaging according to second change gear 72 position and change gear 72 in the axial direction at the peripheral surface place of this second travelling gear 102.The 3rd travelling gear 103 is arranged to so that mesh and disengaging according to second change gear 72 position and second change gear 72 in the axial direction at the peripheral surface place of the 3rd travelling gear 103.Even organize first change gear 71 and second change gear 72 is positioned under the situation at any particular location place at this, second travelling gear 102 and the 3rd travelling gear 103 can be simultaneously and 72 engagements of second change gear.First travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 differ from one another on thickness and have or do not have bevel gear 104, but external diameter is identical.(that is, the right side from Fig. 5 is towards the left side) is arranged on the back shaft 100 in order from maintenance area M1 towards image-recording region A1 for first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103.Between first travelling gear 101 and second travelling gear 102, be provided with the thickness corresponding intervals part 106 of the thickness and second travelling gear 102, so that first travelling gear 101 and second travelling gear 102 are spaced apart from each other.In these were arranged, first travelling gear 101 can only mesh with first change gear 71, and second travelling gear 102 and the 3rd travelling gear 103 can only mesh with second travelling gear 72.
The thickness that each travelling gear in first travelling gear 101 and the 3rd travelling gear 103 has is equal to or slightly greater than the thickness of each change gear in first change gear 71 and second change gear 72.It is to be noted, in this MFD10, first change gear 71 and second change gear 72 have thickness much at one, and this thickness be in first change gear 71 and second change gear 72 each change gear not simultaneously with travelling gear 101,102,103 in the thickness of two or more travelling gears engagement.In addition, in the present embodiment, under the situation that only adopts term " thickness of gear ", term " thickness " refers to the size on thickness axial direction (left and right directions in Fig. 5).On the other hand, the thickness that second travelling gear 102 has is approximately the twice of the thickness of each travelling gear in first travelling gear 101 and the 3rd travelling gear 103, and this thickness for second travelling gear 102 under the situation of organizing first change gear 71 and second change gear 72 at this and being positioned at two arbitrary specific location in the ad-hoc location can with the thickness of second change gear, 72 engagements.
Bevel gear 104 is attached to the right side of first travelling gear 101.Bevel gear 104 has the external diameter bigger than first travelling gear 101, so that form between the bevel gear 104 and first travelling gear 101 from the limiting surface 105 that in the radial direction outwards protrude of first travelling gear 101 at this first travelling gear 101.First change gear 71 is contacted with limiting surface 105, thereby make first change gear 71 on by the direction shown in the arrow 84B, not slide and to move from this first change gear 71 and first travelling gear, 101 position engaged.Therefore, first change gear 71 and first travelling gear 101 keep being engaged with each other, and input bar 74 and engagement member 75 separate with first change gear 71.
Each travelling gear in first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 is used for driving force is passed to selected or corresponding one or more driven portions, driven portion.More particularly, first travelling gear 101 passes to suction pump (first driven portion) in cleaning device 55 etc. with the driving force that the right side is provided with the LF motor 65 of bevel gear 104.Second travelling gear 102 optionally passes to the pivot (the 4th driven portion) of passage switching part 34 and the block hoisting mechanism (second driven portion) of cleaning device 55 with rotating backward with the driving force of ASF motor 66 forward according to this second travelling gear 102.The 3rd travelling gear 103 optionally passes to the first sheet material feed rolls 25 and the second sheet material feed rolls 42 (the 3rd driven portion) with the driving force that rotates backward ASF motor 66 forward according to the 3rd travelling gear 103.The maintenance of the suction pump of cleaning device 55 and block hoisting mechanism and this MFD10 is driven relatively.It is to be noted that in MFD10, " maintenance " of this MFD10 can always not need cleaning operation, and comprise the capping operation that the nozzle with record head 61 covers.In addition, " the presenting " of being undertaken by MFD10 except recording sheet when the operation of image record by sheet material feeding roller 29, sheet material distributing roller 31 with go back to the presenting of roller 35 and also comprise recording sheet presenting by the first sheet material feed rolls 25 and the second sheet material feed rolls 42.
As mentioned above, corresponding in first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 travelling gear is distributed in each driven portion in a plurality of driven portions in the driven portion.From the corresponding travelling gear of first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 driving force is passed to each mechanisms of one or more driven portions corresponding the driven portion as being used for, can adopt the well known organization that uses gear train, belt etc.But this can directly not influence scope and spirit of the present invention, and will omit detailed explanation.
The operation of switching mechanism 70
Operation with reference to table 1 pair switching mechanism 70 describes below, switches in the engagement between first change gear 71 and second change gear 72 and first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 in this operation.

As shown in Figure 4 and 5 and table 1, when the lever arm 77 in being inserted into bullport 86 was positioned at first guide position, 88 places, this organizes first change gear 71 and second change gear 72 is positioned at first specific location.In first specific location, first change gear 71 is positioned at the part place in the space that the distance piece 106 by more close second travelling gear 102 forms.Under this state, pass to arbitrary driven portion from first change gear 71 as the driving force of the LF motor 65 of first drive source.But, can rotate by driving force and sheet material feeding roller 29 with first driven wheel of first change gear 71 engagement as the LF motor 65 of first drive source, and sheet material distributing roller 31 and go back to roller 35 can be according to rotating with the synchronous mode of sheet material feeding roller 29.On the other hand, second change gear 72 and 103 engagements of the 3rd travelling gear.Therefore, the driving force as the ASF motor 66 of second drive source passes to the first sheet material feed rolls 25 or the second sheet material feed rolls 42.First change gear 71 and second change gear 72 are rotated by two motors (that is, LF motor 65 and ASF motor 66) respectively independently of one another.Therefore, in first specific location, can control sheet material supply operation and the operation of the sheet material feeding the first sheet material feeding passage 23 independently of one another from sheet material supplies trays 20 or sheet material supply box 14.Therefore, another recording sheet in can a recording sheet in presenting recording sheet from sheet material supplies trays 20 or sheet material supply box 14 supply recording sheets, and for example in double-sided recording modes, can drive the first sheet material feed rolls 25 in suitable timing in presenting going back to.In addition, when this was organized first change gear 71 and second change gear 72 and is positioned at first specific location, balladeur train 62 can move back and forth in image-recording region A1 under the situation that does not contact input bar 74.It is to be noted, balladeur train 62 from maintenance area M1 when image-recording region A1 moves, set up balladeur train 62 not with lever arm 77 state of contact.Balladeur train 62 not with lever arm 77 state of contact under, this organizes first change gear 71 and second change gear 72 is positioned at first specific location.
Shown in Fig. 7 and table 1, contact (as shown in Figure 4) when making lever arm 77 to the motion of second guide position 89 at guiding piece 92 with lever arm 77 by the motion with balladeur train 62, this organizes first change gear 71 and second change gear 72 by being slided or motion towards second ad-hoc location with the elastic force that lever arm 77 overcomes helical spring 95A by the elastic force pushing of helical spring 95B on by the direction shown in the arrow 84B.Be located axially at second specific location between first ad-hoc location and the 3rd ad-hoc location, first change gear 71 is positioned at the part place in the space that is formed by distance piece 106, more close first travelling gear 101 of this part.Under this state, pass to arbitrary driven portion from first change gear 71 as the driving force of the LF motor 65 of first drive source.But, as in first specific location, sheet material feeding roller 29, sheet material distributing roller 31 and go back to roller 35 and can the driving force by LF motor 65 rotate.That is to say, the driving force of LF motor 65 passes to respectively as with respect to the sheet material feeding roller 29 of presenting driven another driven portion, the sheet material distributing roller 31 of recording medium with go back to roller 35, and whether is positioned at first, second or the 3rd specific location no matter this organizes first change gear 71 and second change gear 72.
Organizing first change gear 71 and second change gear 72 at this slides or during motion, second change gear 72 breaks away from the 3rd travelling gear 103 and meshes with second travelling gear 102 to second ad-hoc location from first ad-hoc location.In second change gear 72 and the 3rd travelling gear 103 breaks away from and during with 102 engagements of second travelling gear, the pressure between the surface of second change gear 72 and the 3rd travelling gear 103 is removed in control by MFD10, so as to make second driven wheel with respect to second driven wheel rotated institute along direction rotation a little in the opposite direction.Then, alternately repeat second change gear 72 with respect to second driven wheel a little forward and rotate backward so that with the rotation phase (that is the anglec of rotation) of second change gear 72 and second travelling gear 102 coupling.Therefore, the rotation phase of second change gear 72 and second travelling gear 102 matches each other, and second change gear 72 is slided on back shaft 73 or is moved by the elastic force of helical spring 95B, so that mesh with 103 disengagings of the 3rd travelling gear with second travelling gear 102.The rotation of first change gear 71 and be used to remove the pressure between the surface and be used to make rotation phase coupling second change gear 72 forward and rotate backward and can be controlled independently of one another.That is to say that in second change gear 72 forward and when rotating backward, first change gear 71 can be static and be rotated along a direction.In addition, this organize first change gear 71 and second change gear 72 from first ad-hoc location when second ad-hoc location moves, first change gear 71 not with first travelling gear 101, second travelling gear 102 and the 3rd travelling gear 103 in arbitrary travelling gear engagement.Therefore, needn't control the rotation of first change gear 71, so that remove the pressure between the surface and make the rotation phase coupling.
Second travelling gear 102 optionally passes to the block hoisting mechanism of cleaning device 55 and the pivot of passage switching part 34 with the driving force of ASF motor 66.In other words, in the state that second travelling gear 102 and second change gear 72 match each other, allow the driving force of ASF motor 66 to pass to second driven portion or the 5th driven portion (that is another driven portion).First change gear 71 and second change gear 72 are rotated by LF motor 65 and ASF motor 66 respectively independently of one another.Therefore, in second specific location, the capping operation of the passage handover operation of passage switching part 34 or nozzle block 57 and the operation of the sheet material feeding in the first sheet material feeding passage 23 can easily independent controls.
For example, in double-sided recording modes, when stopping the presenting of recording sheet so that China ink when record head 61 being covered when becoming dry, makes balladeur train 62 move to position directly over the nozzle block 57.In this operation, the guiding piece 92 of balladeur train 62 is contacted with lever arm 77, lever arm 77 is to 90 motions of the 3rd guide position thus, but as will be described below, because second change gear 72 keeps and 102 engagements of second travelling gear, can nozzle block 57 be promoted by the driving force of ASF motor 66.First change gear 71 can mesh with first travelling gear 101 when lever arm 77 moves to the 3rd guide position 90.When stopping the presenting of recording sheet, whether first change gear 71 can depend on whether the rotation phase of first change gear 71 and first travelling gear 101 mates each other with 101 engagements of first travelling gear.But, since recording sheet present stop in LF motor 65 stop, even so under the situation that first change gear 71 is passed through to mesh with first travelling gear 101 sliding on the back shaft 73, first change gear 71 also can break away from first travelling gear 101 by sliding on back shaft 73, and move to first guide position 88 or second guide position 89 by lever arm 77 after the engagement of first change gear 71, thereby can not remove the pressure between the surface of first change gear 71 and first travelling gear 101.
Balladeur train 62 is moved to image-recording region A1.Therefore, guiding piece 92 makes lever arm 77 move to first guide position 88 from the 3rd guide position 90.When first guide position 88 moved, second change gear 72 and the 3rd travelling gear 103 meshed at lever arm 77.That is to say, carry out the releasing of pressure between the surface and the coupling of rotation phase, so that second change gear 72 and 103 engagements of the 3rd travelling gear by control ASF motor 66.In addition, make balladeur train 62, so that guiding piece 92 makes lever arm 77 move to second guide position 89 from first guide position 88 to maintenance area M1 motion.According to this motion of lever arm 77, this organizes first change gear 71 and second change gear 72 turns back to second ad-hoc location, so that second change gear 72 and the 3rd travelling gear 103 break away to mesh with second travelling gear 102.In these external these operations, the releasing by controlling pressure between the surface that ASF motor 66 carries out second change gear 72 and the 3rd travelling gear 103 in the mode identical and the coupling of second change gear 72 and second travelling gear, 102 rotation phase with aforesaid way.On the other hand, after first change gear 71 and first travelling gear 101 break away from, first change gear 71 not with travelling gear 101,102,103 in arbitrary travelling gear engagement.Therefore, the coupling of rotation phase does not need to be undertaken by the LF motor 65 that is used to present recording sheet the coupling of rotation phase.Therefore, easily control switching mechanism 70 in selected one or more driven portions driving force being passed in the driven portion.
Shown in Fig. 8 and table 1, move to position directly over the nozzle block 57 according to balladeur train 62, guiding piece 92 is contacted with lever arm 77, thereby make lever arm 77 move to the 3rd guide position 90 shown in Figure 4.Therefore, this organize first change gear 71 and second change gear 72 the elastic force by helical spring 95B under balladeur train and lever arm 77 state of contact on by the direction shown in the arrow 84B towards the motion of the 3rd ad-hoc location or slide.In other words, this organize first change gear 71 and second change gear 72 in ad-hoc location an ad-hoc location and another ad-hoc location between when sliding, first travelling gear 71 and between the state of first change gear, 71 engagements does not switch at the state and first travelling gear 101 of first travelling gear 101 and 71 engagements of first change gear, and second travelling gear 72 remains in the state of second travelling gear 102 and 72 engagements of second change gear simultaneously.It is to be noted, move to the 3rd guide position 90 according to lever arm 77, first change gear 71 is contacted with the limiting surface 105 of first travelling gear 101, thereby be limited and on by the direction shown in the arrow 84B, further slide or motion, so that this group first change gear 71 and second change gear 72 remain on the 3rd specific location.Input bar 74 and engagement member 75 further move with balladeur train 62 on by the direction shown in the arrow 84B, so that the engagement member 75 and first change gear 71 break away from, and lever arm 77 moves to the 3rd guide position 90.
In the 3rd specific location, first change gear 71 and 101 engagements of first travelling gear.When first change gear 71 and the engagement of first travelling gear 101, alternately repeat first change gear 71 with respect to first driven wheel a little forward and rotation backward so that make first change gear 71 and the rotation phase of first travelling gear 101 coupling.Therefore, the rotation phase of first change gear 71 and first travelling gear 101 is matched each other, mesh with first travelling gear 101 so that first change gear 71 is slided on back shaft 73 by the elastic force of helical spring 95B.The rotation of second change gear 72 and being used to make the rotation phase coupling first change gear 71 forward and rotate backward and can be controlled independently of one another.That is to say that in first change gear 71 forward and when rotating backward, second change gear 72 can be static and be rotated along a direction.
In addition, in the 3rd specific location, when moving on back shaft 73 or slide, second change gear 72 keeps and 102 engagements of second travelling gear.That is to say, this organize first change gear 71 and second change gear 72 from second ad-hoc location when the 3rd ad-hoc location moves, second change gear 72 with 102 engagements of second travelling gear on back shaft 73, slide.Therefore, needn't control the rotation of second change gear 72 so that the rotation phase coupling.
Balladeur train 62 can move back and forth in the M1 of maintenance area in that this that be positioned at second specific location organized under the situation of first change gear 71 and 72 motions of second change gear.The driving force of LF motor 65 passes to the suction pump of cleaning device 55 etc. by first change gear 71 and first travelling gear 101, so that carry out the operation relevant with the maintenance of MFD10.On the other hand, the driving force of ASF motor 66 passes to the block hoisting mechanism of cleaning device 55 by second change gear 72 and second travelling gear 102, so that carry out the capping operation of record head 61.
The effect of this MFD10
In this MFD10, first change gear 71 and second change gear 72 are supported to and can be slided on balladeur train 62 reciprocating predetermined directions by back shaft 73.In addition, the guiding piece 92 of balladeur train 62 is contacted with input bar 74, the elastic force that overcomes helical spring 95A thus makes first change gear 71 and 72 motions of second change gear, so that optionally be positioned at a specific location in first, second and the 3rd ad-hoc location.Therefore, can reduce the load of bearing by balladeur train 62 during to another ad-hoc location motion at first change gear 71 and second change gear 72 ad-hoc location from first, second and the 3rd ad-hoc location.Therefore, the CR motor of reduced size can be made balladeur train 62 reciprocating drive sources with acting on, thereby reduce power consumption.
Switch according to this position of organizing first change gear 71 and second change gear 72, when first change gear 71 and 101 engagements of first travelling gear, second change gear 72 is kept and 102 engagements of second travelling gear.Therefore, can take such state, in this state, when second change gear 72 keeps stopping, drive first change gear 71 and rotate so that the rotation phase of first change gear 71 and first travelling gear 101 is mated.In addition, break away from so that during with 102 engagements of second travelling gear at second change gear 72 and the 3rd travelling gear 103, first change gear 71 is positioned at the position corresponding with distance piece 106.Therefore, can take such state, in this state, when first change gear 71 keeps stopping, drive second change gear 72 and rotate with the pressure between the surface of removing second change gear 72 and the 3rd travelling gear 103 and make second change gear 72 and the rotation phase of second travelling gear 102 coupling.Therefore, owing to improved the flexibility of controlling first change gear 71 and the 72 corresponding rotations of second change gear, so can under the situation that does not drive two motors, switch the gear meshing that is used for the driving force of two motors (that is, LF motor 65 and ASF motor 66) is passed to selected one or more driven portions in the driven portion in suitable timing.In addition, the coupling of the coupling of first change gear 71 and second change gear 72 needn't be carried out simultaneously, thereby reduces the time be used to control first change gear 71 and the 72 corresponding rotations of second change gear, thereby and improves the reliability of driving force transmission system.
In this MFD10, balladeur train 62 can not make under the situation of first change gear 71 that is positioned at the 3rd specific location and 72 motions of second change gear and move back and forth in the M1 of maintenance area.In addition, balladeur train 62 can move back and forth in image-recording region A1 in that this that be positioned at first specific location organized under the situation of first change gear 71 and 72 motions of second change gear.When this was organized first change gear 71 and second change gear 72 and is positioned at the 3rd specific location, the switching mechanism 70 of the maintenance of driving force by being used to carry out MFD10 transmitted.When this was organized first change gear 71 and second change gear 72 and is positioned at first specific location, driving force was by being used to comprise that the switching mechanism of presenting from the recording sheet of sheet material supplies trays 20 and sheet material supply box 14 supply recording sheets 70 transmits.Therefore, can under the situation that does not depend on the position of balladeur train 62 in each zone, carry out the maintenance of MFD10 and presenting of recording sheet.
