Fig. 5 a and Fig. 5 b is the sectional elevation representing balladeur train 3 and guiding elements 4, shows and observes from the x direction upstream side shown in Fig. 3 the state obtained towards downstream side.Fig. 5 a is the sectional elevation representing the state made before bearing components 21 displacement, Fig. 5 b be represent make bearing components 21 move after the sectional elevation of state.By making eccentric cam 26 rotate, thus making bearing components 21 displacement (straight-line displacement), changing the position (hereinafter referred to as " abutting portion ") abutted against with the 1st guiding elements 4 of bearing components 21.As shown in figure 5 a and 5b, pair of bearings component 21 (the 1st abutting member, the 2nd abutting member) supports can maintain the constant mode supported portion 22 of carrying out displacement of angle theta.
In addition, as shown in figure 5 a and 5b, the upper surface by z direction upstream side of bearing components 21 and the lower surface by downstream side, z direction of lobe plate 25 abut against.Lobe plate 25 is can configure to the mode of the upstream side in z direction and downstream side displacement, and the upper surface by z direction upstream side and the eccentric cam 26 of lobe plate 25 abut against.Bearing components 21 is biased component 24 and exerts a force towards from the direction of the oblique upstream side in downstream side, z direction.
1st guiding elements 4 is made by compared with bearing components 21, compared with the material of hard, and the hardness of the 1st guiding elements 4 is higher than the hardness of bearing components 21.Therefore, along with the number of times of the scanning movement in the x direction of balladeur train 3 is namely relative to the increase of the slip number of times of the 1st guiding elements 4, the abutting portion of bearing components 21 can be worn and torn.Because effect has the gravity from z direction upstream side towards downstream side on balladeur train 3, therefore, make the position of balladeur train 3 to the change in location in downstream side, z direction because of the wearing and tearing of the abutting portion of bearing components 21.Thus, there is following situation: the distance be mounted between print head 2 on balladeur train 3 and sheet material 1 changes, thus make the imparting position skew of ink on sheet material 1 and image quality is reduced.
Therefore, in the present embodiment, when the abutting portion of bearing components 21 there occurs wearing and tearing, change abutting portion, thus make the region not having to wear and tear of bearing components 21 or less region of wearing and tearing become the abutting portion abutted against with the 1st guiding elements 4.Thus, the distance between print head 2 and sheet material 1 be maintained the distance of expectation and suppress the reduction of image quality.By making bearing components 21 straight-line displacement on the direction that the bearing of trend with the 1st guiding elements 4 intersects, thus change the abutting portion abutted against with the 1st guiding elements 4 of bearing components 21.
When making eccentric cam 26 rotate from the state shown in Fig. 5 a, become the state shown in Fig. 5 b.Set the shape of eccentric cam 26 as follows, such that eccentric cam 26 have rotated about 90 degree when observing from the front of accompanying drawing, the power putting on bearing components 21 via lobe plate 25 from eccentric cam 26 becomes maximum.The power that the power applying by utilizing eccentric cam 26 pairs of bearing components 21 to apply than force application component 24 pairs of bearing components 21 is large, thus make bearing components 21 obliquely to the downstream side straight-line displacement of z direction.
In addition, in figure 5b, illustrate and make eccentric cam 26 have rotated the situation of about 90 degree from the state shown in Fig. 5 a, as long as but can by make eccentric cam 26 rotate make bearing components 21 displacement, then eccentric cam 26 angle and be not particularly limited.The angle that eccentric cam 26 is rotated suitably can be adjusted, to adjust the displacement distance of bearing components 21.
As shown in Figure 5 b, when making bearing components 21 to the downstream side displacement of z direction, the abutting portion abutted against with the 1st guiding elements 4 of bearing components 21 become bearing components 21, than the region of the abutting portion under the state shown in Fig. 5 a by z direction upstream side.Like this, by making eccentric cam 26 rotate, thus the active force applied from eccentric cam 26 pairs of bearing components 21 being changed, making bearing components 21 displacement.
At this, describe and make bearing components 21 from the position shown in Fig. 5 a to the situation of the position displacement shown in Fig. 5 b, but also can be, make bearing components 21 from the position shown in Fig. 5 b to the position displacement shown in Fig. 5 a.In addition, eccentric cam 26 is configured to when printing the balladeur train 3 in course of action and scanning mobile, eccentric cam 26 can not rotate under the effect of the reaction force from force application component 24, eccentric cam 26, under the effect of driving mechanism (driver part), postrotational state can be maintained, will be described driving mechanism later with reference to Fig. 6 and Fig. 7.
Fig. 6 is the stereogram representing the driving mechanism making bearing components 21 displacement, and Fig. 7 is the stereogram of the action for illustration of driving mechanism.In addition, in figure 6, the diagram of the idler gear 35,36 shown in Fig. 7 is eliminated.As shown in Figure 6 and Figure 7, lifter cam 31 is provided with in one end of axle 70.Under the state shown in Fig. 6 and Fig. 7, lifter cam 31 is located at than the position of eccentric cam 26 by x direction upstream side, utilizes the rotation of the axle 70 caused by the rotation of lifter cam 31 to rotate to make eccentric cam 26.
Be configured with at the inner side surface 39 of the housing of printing device 100 and connect cam 32, lift motor 33 and light transmission type sensor 38.In addition, lift motor 33 is stepper motors, and it is the driving source of the driving force that can produce for making bearing components 21 displacement.Driving force from lift motor 33 is passed to bearing components 21 from transfer part and makes bearing components 21 displacement, this transfer part comprise the motor gear 34 shown in Fig. 7, idler gear 35,36, connect cam 37,32, lifter cam 31 and eccentric cam 26.
When bearing components 21 displacement will be made, make balladeur train 3 move to lifter cam 31 and connect the position that cam 32 can be fitted together to, and make lifter cam 31 and connect cam 32 tabling, thus make balladeur train 3 move stopping.Then, utilize the control from CPU51 to drive to make lift motor 33, motor gear 34 is rotated, this rotation is passed to via idler gear 35,36 and connects cam 37.Connect cam 37 and connect cam 32 and directly link, connection cam 32 rotates linkedly with the rotation connecting cam 37, thus makes to rotate with the lifter cam 31 connecting cam 32 tabling.Thus, axle 70 rotates, and eccentric cam 26 rotates along with the rotation of axle 70, bearing components 21 correspondingly displacement according to the force from eccentric cam 26.
As shown in Figure 6 and Figure 7, lifter cam 31 is provided with covering 31a.Light transmission type sensor 38 has the light-emitting component for sending light and the light receiving elements for being received from the light that light-emitting component sends, and light transmission type sensor 38 is configured at such position: the position of the covering 31a that can change to the rotation along with lifter cam 31 is detected.When lifter cam 31 rotates, covering 31a is configured in the scope that light transmission type sensor 38 can read, thus hinders light to arrive the light receiving elements of light transmission type sensor 38.According to the amount of the light received by light receiving elements and the transit dose of light, the angle of swing to the position of covering 31a and eccentric cam 26 detects light transmission type sensor 38.CPU51 obtains the information relevant with the angle of swing of eccentric cam 26 from light transmission type sensor 38, if this angle of swing does not meet the angle of swing for making bearing components 21 move to the position of expectation, then the pulsed drive making lift motor 3 carry out further specifying and eccentric cam 26 is rotated.
Next, the flow process of the process for making bearing components 21 displacement is described.In the present embodiment, determine whether making bearing components 21 displacement according to the distance between print head 2 and the platen 11 being placed with sheet material 1 when recording.
Fig. 8 is the flow chart representing the handling process making bearing components 21 displacement.As shown in Figure 8, first, before starting to print action, optical sensor 10 is used to measure (S1) the distance X1 between print head 2 and platen 11.Next, obtain when the dispatching from the factory of printing device 100, between print head 2 and platen 11 distance X and deduct distance X1 and the distance obtained.At this, the distance between print head 2 and platen 11 narrows and the amount narrowed is greater than the distance measurements of distance X2, will likely make image quality reduce.Therefore, if the distance deducting distance X1 from distance X and obtain is below distance X2 (situation being yes in S2), does not then make bearing components 21 displacement, namely do not make eccentric cam 26 rotate but terminate present treatment, and start to print action.
On the other hand, under the distance obtained deducting distance X1 from distance X is greater than the situation (situation being no in S2) of distance X2, in order to make bearing components 21 displacement change abutting portion, eccentric cam 26 is rotated (S3).Specifically, CPU51 correspondingly makes lift motor 33 carry out driving according to the distance between the print head 2 using optical sensor 10 to record and platen 11 and motor gear 34 is rotated.Further, the rotation of motor gear 34 is passed to via idler gear 35,36 connects cam 37,32 and lifter cam 31 and eccentric cam 26 is rotated.CPU51 obtains the information relevant with the angle of swing of eccentric cam 26 from light transmission type sensor 38, and according to this information, eccentric cam 26 is rotated and make bearing components 21 displacement, to make the distance between print head 2 and platen 11 become the distance of expectation.Then, described process (S1 ~ S2) is again repeated.
Determine whether making bearing components 21 displacement by processing above.When bearing components 21 and abutting portion that the 1st guiding elements 4 abuts against occurs to wear and tear and makes the distance between print head 2 and platen 11 be less than the distance of expectation, make bearing components 21 displacement and abutting portion changed.That is, balladeur train 3 is supported by the 1st guiding elements 4 axle, makes abutting portion change that still unworn region is used as abutting portion, thus makes the distance between print head 2 and platen 11 become the distance of expectation.Thereby, it is possible to suppress the abutting portion because of bearing components 21 that wearing and tearing occur and make the distance between print head 2 and platen 11 change the reduction of caused image quality.In addition, even if when the abutting portion abutted against with the 1st guiding elements 4 of bearing components 21 there occurs wearing and tearing, by suitably changing abutting portion, the replacement frequency of the part of bearing components 21 also can be suppressed, thus significantly can promote non-maintainingization.
At this, variation is described.In this variation, make bearing components 21 displacement according to for making the current value of balladeur train 3 movement determine whether.Other structures are identical with the 1st mode of execution, and therefore, the description thereof will be omitted.In addition, utilize not shown velocity transducer to measure the travelling speed of balladeur train 3.
Fig. 9 is the flow chart making the handling process of bearing components 21 displacement represented in this variation.First, before carrying out printing action, to for making balladeur train 3 measure (S11) with the current value A1 of fixing speed movement.Obtain the current value for making balladeur train 3 obtain with the current value A of fixing speed movement when current value A1 deducts the dispatching from the factory of printing device 100.
When the current value needed to make balladeur train 3 move with fixing speed higher than when dispatching from the factory make balladeur train 3 with the current value of fixing speed movement, slip load increase, rubbish, ink etc. are attached between the 1st guiding elements 4 and bearing components 21 sometimes.When rubbish etc. is attached between the 1st guiding elements 4 and bearing components 21, stably cannot control the movement of balladeur train 3, likely make image quality reduce.In addition, when rubbish etc. is attached between bearing components 21 and the 1st guiding elements 4, bearing components 21 not only can be made to wear and tear, also can damage the 1st guiding elements 4.When damage the 1st guiding elements 4, according to the difference of the degree of damage, sometimes need replacing the 1st guiding elements 4.
Therefore, at this, when need to make balladeur train 3 move with fixing speed following current value, namely on current value A, add the current value being greater than current value A2 and the current value obtained, the larger slip load of impact brought to image quality increases, and is accompanied by this and drives load to increase.In this case, make bearing components 21 displacement and remove rubbish etc., and changing the abutting portion of bearing components 21.
If the current value deducting current value A from current value A1 and obtain being below current value A2 (in S12 for being), not making eccentric cam 26 rotate but present treatment is terminated, and starting to print action.On the other hand, in the situation (situation being no in S12) that the current value obtained deducting current value A from current value A1 is greater than current value A2, making eccentric cam 26 rotate (S13) and again repeating described process (S11 ~ S12).
Through above process, in this variation, stably can control the movement of balladeur train 3 and suppress the reduction of image quality, and, the replacement frequency of bearing components 21 and the 1st guiding elements 4 can be suppressed, significantly promote non-maintainingization.
2nd mode of execution
In the 2nd mode of execution, the structure of bearing is different from the 1st mode of execution.Other structures are identical with the 1st mode of execution, and therefore, the description thereof will be omitted.
Figure 10 is the stereogram representing balladeur train 3 and the 1st guiding elements 4.As shown in Figure 10, the two end part on the x direction of balladeur train 3 are provided with bearing 29.Each bearing 29 is configured with bearing components 27.The bearing components 27 being positioned at a tip side on x direction utilizes connecting rod 30 to be connected with the bearing components 27 being positioned at another tip side.
Figure 11 is the sectional elevation representing balladeur train 3 and the 1st guiding elements 4, represents that observing institute from the x direction upstream side shown in Figure 10 towards downstream side obtains state.As shown in figure 11, bearing 29 has two supports 28, each support 28 block bearing component 27 (contact pad).Two supports 28 are block bearing components 27 respectively, thus can maintain the constant bearing components 27 that makes of angle theta and rotate, and wherein, this angle theta is the angle between the face in the face that comprising of bearing components 27 and the 1st guiding elements 4 abut against.Bearing components 27 as follows supported portion 28 supports, that is: can carry out swing offset centered by the axle extended along the direction vertical with the face being formed angle theta.In addition, in a same manner as in the first embodiment, bearing components 27 as follows supported portion 28 supports, that is: the face comprising the face abutted against with the 1st guiding elements 4 when observing in the x-direction forms inverted V-shape.To clip the mode of the 1st guiding elements 4 to configure balladeur train 3 between the pair of bearings component 27 (the 1st abutting member, the 2nd abutting member) forming inverted V-shape.
Figure 12 a and Figure 12 b is the stereogram representing bearing components 27, is the stereogram of the spinning movement for illustration of bearing components 27.In addition, in Figure 12 a and Figure 12 b, the diagram of balladeur train 3 is eliminated.
As depicted in figs. 12 a and 12b, bearing components 27 has linking department 27b and jut 27c.Fasten by making the projection 27c of bearing components 27 (the 1st engagement portion) and projection 44a, 45a (the 2nd engagement portion), thus make bearing components 27 carry out swing offset, will be described projection 44a, 45a later with reference to Figure 13 and Figure 14.The linking department 27b being configured at the bearing components 27 of the end on x direction utilizes connecting rod 30 to be connected with the linking department 27b of the bearing components 27 being configured at the other end.Therefore, when the bearing components 27 of an end carries out swing offset, with its rotation linkedly, the bearing components 27 of the other end carries out swing offset.Bearing components 27 is plectane components.
Under the state shown in Figure 12 a, the region be illustrated by the broken lines on the opposing side relative with the 1st guiding elements 4 of bearing components 27 is the abutting portion that bearing components 27 and the 1st guiding elements 4 abut against.When making bearing components 27 rotate from the state shown in Figure 12 a, become the state shown in Figure 12 b.Under the state shown in Figure 12 b, the region represented by single dotted broken line on the opposing side relative with the 1st guiding elements 4 of bearing components 27 becomes the abutting portion that bearing components 27 and the 1st guiding elements 4 abut against.By so making bearing components 27 rotate, thus abutting portion is changed.In addition, the rotation axis off-center of bearing components 27 can also be made.In addition, the abutting portion on bearing components 27 also can be the region without rotating center, that is, also can be, on the opposing side relative with the 1st guiding elements 4 of bearing components 27, abutting portion and the region with rotating center are different regions.
Figure 13 is the stereogram representing the driving mechanism that bearing components 27 is rotated, and Figure 14 is the stereogram of the action for illustration of driving mechanism.As shown in figure 13, motor gear 34, idler gear 41 ~ idler gear 43, lifter wheel 44,45 (Japanese: リ Off ト ギ ヤ) and light transmission type sensor 38 is configured with at the inner side surface 40 of the housing of printing device 100.Utilize driving mechanism to rotate to make bearing components 27, this driving mechanism has the lift motor 33 shown in Figure 14, motor gear 34, idler gear 41 ~ idler gear 43, lifter wheel 44,45.Lifter wheel 44 is provided with projection 44a and covering 44b.Lifter wheel 45 is provided with projection 45a.The projection 44a of lifter wheel 44 is arranged on the position that the projection 27c that can be configured at y direction upstream side with the end of swimming side in the x direction of bearing components 27 fastens.The projection 45a of lifter wheel 45 is arranged on the position that the projection 27c that can be configured at downstream side, y direction with the end of swimming side in the x direction of bearing components 27 fastens.
When bearing components 27 will be made to rotate, the position that the projection 27c being configured at x direction upstream side making balladeur train 3 move to bearing components 27 can engage with projection 44a, the 45a of lifter wheel 44,45, the projection 27c of the x direction upstream side of bearing components 27 and projection 44a, the 45a of lifter wheel 44,45 is fastened, and the mobile of balladeur train 3 is stopped.Then, make lift motor 33 carry out driving and motor gear 34 being rotated, this rotation is passed to lifter wheel 44,45 via idler gear 41 ~ idler gear 43.By making lifter wheel 44,45 rotate, thus projection 44a, the 45a of lifter wheel 44,45 also being rotated, making the projection 27c displacement fastened with projection 44a, 45a, make bearing components 27 carry out swing offset thus.
The position that the position that light transmission type sensor 38 is configured at the covering 44b that can change to the rotation along with lifter wheel 44 is detected.Light transmission type sensor 38 detects the position of covering 44b according to the amount of the light received from light receiving elements thus detects the angle of swing of bearing components 27.If this angle of swing does not meet the desired angle, then the CPU51 pulsed drive that makes lift motor 33 carry out further specifying and make bearing components 27 carry out swing offset.
Next, the flow process making bearing components 27 carry out the process of swing offset is described.In the present embodiment, determine whether bearing components 27 is rotated according to the distance between print head 2 and the platen 11 being placed with sheet material 1 when recording.
Figure 15 is the flow chart representing the handling process that bearing components 27 is rotated.In addition, the process of the S21 ~ S22 shown in Figure 15 is the process identical with the process of the S1 ~ S2 shown in Fig. 8 of the 1st mode of execution.As shown in figure 15, first, before starting to print action, optical sensor 10 is used to measure (S21) the distance X1 between print head 2 and platen 11.If when the dispatching from the factory of printing device 100, between print head 2 and platen 11 distance X deducts distance X1 and the distance obtained is below distance X2 (situation being yes in S22), then do not make bearing components 27 rotate but terminate present treatment, and start to print action.
On the other hand, the distance obtained deducting distance X1 from distance X makes bearing components 27 rotate (S23) under being greater than the situation (situation being no in S22) of distance X2.Specifically, CPU51 correspondingly makes lift motor 33 carry out driving according to the distance between the print head 2 using optical sensor 10 to record and platen 11 and motor gear 34 is rotated.Further, the rotation of motor gear 34 is passed to lifter wheel 44,45 via idler gear 41 ~ idler gear 43, and makes bearing components 27 rotate as described above.Then, described process (S21 ~ S22) is again repeated.
Determine whether bearing components 27 is rotated by processing above.When bearing components 27 and abutting portion that the 1st guiding elements 4 abuts against occurs to wear and tear and makes the distance between print head 2 and platen 11 be less than the distance of expectation, make bearing components 27 rotate and abutting portion is changed.That is, balladeur train 3 is supported by the 1st guiding elements 4 axle, makes abutting portion change that still unworn region is used as abutting portion, thus makes the distance between print head 2 and platen 11 become the distance of expectation.Thus, can suppress the abutting portion because of bearing components 27 that wearing and tearing occur and the distance between print head 2 and platen 11 is changed the reduction of caused image quality, further, the replacement frequency of bearing components 27 can also be suppressed, thus significantly can promote non-maintainingization.
Below, several variation is described.In this variation, according to for making balladeur train 3 determine whether making bearing components 27 rotate with the current value of fixing speed movement.Other structures are identical with the 2nd mode of execution, and therefore, the description thereof will be omitted.
Figure 16 is that the bearing components 27 that makes represented in this variation carries out the flow chart of the handling process rotated.In addition, the process of the S31 ~ S32 shown in Figure 16 is the process identical with the process of the S11 ~ S12 shown in Fig. 9 of the 1st mode of execution.First, before carrying out printing action, balladeur train 3 is moved with fixing speed, measure current value A1 (S31) now.If when current value A1 deducts dispatching from the factory of printing device 100, for balladeur train 3 is obtained with the current value A of fixing speed movement current value for below A2 (situation being yes in S32), then do not make bearing components 27 rotate but terminate present treatment, and start to print action.On the other hand, in the situation (situation being no in S32) that the current value obtained deducting current value A1 from current value A is greater than current value A2, bearing components 27 is rotated (S33), and again repeats described process (S31 ~ S32).
When being attached with rubbish etc. and making slip load increase in the same manner as the variation of the 1st mode of execution between the 1st guiding elements 4 and bearing components 27, through processing above, bearing components 27 is rotated and by removals such as rubbish.Thereby, it is possible to suppress the increase driving load, can stably control the movement of the balladeur train 3 slided relative to the 1st guiding elements 4.
Figure 17 is the sectional elevation of another variation representing bearing components.In said embodiment, describe following situation: bearing components is flat component, the face (opposing side) comprising the abutting portion abutted against with the 1st guiding elements 4 of bearing components is plane.But as shown in figure 17, the opposing side 61a (surface of contact) relative with the 1st guiding elements 4 of bearing components 61 also can be sphere.In addition, as shown in figure 17, also can be that bearing components 61 can rotate centered by the axle 60 that extends by the axis being parallel with the 1st guiding elements 4.
When shown in Figure 17, by exerting a force by lobe plate 25 pairs of bearing components 61 from eccentric cam 26, and make bearing components 61 carry out rotating (swing offset), thus change the abutting portion abutted against with the 1st guiding elements 4 on the surface of contact 61a of bearing components 61.In addition, when for this structure, bearing components 61 is exerted a force to direction as follows by not shown force application component, namely, with the effect be subject to from the force of eccentric cam 26 and rotate side in the opposite direction, thus bearing components 61 is maintained under the effect of the force from eccentric cam 26 rotate after position.
In addition, such as, bearing components also can be the component of cylindrical shape.In this case, by make bearing components by along and the axle that extends of the direction that the bearing of trend of the 1st guiding elements intersects or the direction parallel with the bearing of trend of the 1st guiding elements centered by rotate, the abutting portion abutted against with the 1st guiding elements that can change bearing components.When rotating centered by the axle that the direction that bearing components will be made to intersect with the bearing of trend of the 1st guiding elements by edge extends, also can be, after the direction displacement making bearing components edge and the bearing of trend of the 1st guiding elements intersect, make bearing components carry out swing offset, thus change abutting portion.In addition, in the example above, use the driving force of driving source to make bearing components displacement (straight-line displacement or swing offset), but also can be do not use driving source, but user manually makes bearing components displacement.As long as the abutting portion abutted against with guiding elements that so can change bearing portion, its method, mechanism just not circumscribed.
Although describe the present invention with reference to embodiment, should be appreciated that and the invention is not restricted to disclosed embodiment.The scope of appended claims should meet the most wide in range explanation, to comprise all distortion, equivalent structure and function.
