Be recorded thing 100 behind above-mentioned holding state insertion tape deck 10, backer roll 310 and conveying roller 324 rotations, clamping is recorded thing 100 and is transported to and correcting plate 360 position contacting.At this moment, be recorded under the situation of thing 100 with respect to the throughput direction inclination, a part that is recorded thing 100 contacts with correcting plate 360 earlier, and this moment, other parts did not contact with correcting plate 360 yet.Under this state, after backer roll 310 and conveying roller 324 are further rotated, be recorded the part that contacts with correcting plate 360 not yet of thing 100, be transported to and correcting plate 360 position contacting by the backer roll 310 and the conveying roller 324 that are arranged near this part, and the part that has contacted with correcting plate 360 is not before this further carried.At this moment, promoted to push be recorded thing 100 to because backer roll 310 has the correction of more weak motive force with torsion bar 342, thus be recorded thing 100 before this with part that correcting plate 360 contacts near set backer roll 310 and conveying roller 324 dally being recorded on the thing 100.By being arranged near the optical pickocff (not shown) the correcting plate 360, judge that being recorded thing 100 has been corrected after, stop the rotation of backer roll 310 and conveying roller 324.

After being recorded thing 100 corrections, electing parts 351 and descend.Thus, electing parts 351 makes the conveying that is pushed up contact with the V-type groove 314 of torsion bar 344 with pressurization roll shaft 312.Then, with the continuation decline interlock of electing after parts 351 drop to assigned position, correcting plate 360 also descends.Correcting plate 360 drops to behind the position that the carrying path that is recorded thing 100 is kept out of the way, and stops in this position, and it is also consistent with it and stop to descend to elect parts 351.

After correcting plate 360 and election parts 351 stopped, backer roll 310 and conveying roller 324 rotated once more, and clamping is recorded thing 100 and is transported in the platen portion 50, carries out record by record portion 20.At this moment, backer roll 310 utilizes stronger motive force to be pushed to torsion bar 344 to be recorded thing 100 via pressurization roll shaft 312, by proofread and correct promoting with torsion bar 342 and carry, thus backer roll 310 and conveying roller 324 reliably clamping also conveying be recorded thing 100.

Figure 12 is the partial sectional view of electing mechanism 350.In Figure 12, expression correcting plate 360 is kept out of the way from the carrying path that is recorded thing 100, and carries the state that promotes with 344 pairs of pressurizations of torsion bar roll shaft 312.

As shown in figure 12, electing mechanism 350 has: be provided with groove 355, be inserted with the spring hand side press parts of carrying with torsion bar 344 354 in this groove 355, the follower hand side press parts 352 that contact below with these spring hand side press parts 354, with the tabular follow-up unit 368 that extends along the vertical direction of follower hand side press parts 352 one, and the cam 390 that can be supported on the body 11 rotatably, follow-up unit 368 is moved back and forth up and down as follower around rotating shaft 394.Above-mentioned spring hand side press parts 354 and follower hand side press parts 352 constitute elects parts 351.

As mentioned above, follow-up unit 368 constitutes one on top and follower hand side press parts 352.And,, correcting plate 360 is being set by helical spring 362 on the top of follow-up unit 368.In the substantial middle position of the above-below direction of follow-up unit 368, the long slotted hole 364 of above-below direction is being set, in this slotted hole 364, be inserted with the rotating shaft 394 of cam 390.And, in the bottom of follow-up unit 368, the otch 366 of lower opening is being set, in this otch 366, be inserted with the follower fixed axis 396 that is fixed in body 11.Between the above-mentioned slotted hole 364 and otch 366 of follow-up unit 368, connect pin 398 is installed.

Cam 390 has the shape of approximate plectane, with the side of follow-up unit 368 subtends on, the cam path 392 with whirlpool shape.In cam path 392, be inserted with an end of the pin 398 that connects follow-up unit 368 installations.

Under state shown in Figure 12, pin 398 is in the position of leaving from rotating shaft 394 in the cam path 392 of whirlpool shape.Thus, follow-up unit 368 is in the lower position of movable range with respect to the body 11 that is supporting rotating shaft 394.When follow-up unit 368 was in lower position, the correcting plate 360 that is arranged on correcting plate 360 tops was in the carrying path below that is recorded thing 100, avoids from carrying path.Similarly, the follower hand side press parts 352 that are attached at follow-up unit 368 tops also are in lower position, and the spring hand side press parts 354 that contact with follower hand side press parts 352 allow to carry with torsion bar 344 and promote pressurization roll shafts 312.

In order to become holding state from this state, by not shown driving mechanism, cam 390 drives along the direction of arrow rotation of the solid line among Figure 12.Cam 390 is then sold 398 and is promptly risen with respect to cam 390 along cam path 392 along direction of arrow rotation.At this moment because rotating shaft 394 and follower fixed axis 396 are inserted in slotted hole 364 and the otch 366, so at cam 390 when the direction of arrow is rotated, follow-up unit 368 can be not to the left and right direction rise with respect to body 11 on the bias.

Figure 13 is that expression correcting plate 360 enters the carrying path that is recorded thing 100 and carries the partial sectional view of the state that leaves from the roll shaft 312 that pressurizes with torsion bar 344.From state shown in Figure 12, by cam 390 rotations, after follow-up unit 368 rose, as shown in figure 13, the upper end of correcting plate 360 contacted with the bottom surface 384 of backer roll body side frame 380.Thus, correcting plate 360 enters the carrying path that is recorded thing 100.

After cam 390 is further rotated from this state, because correcting plate 360 contacts with bottom surface 384, so can not continue to rise, but because between correcting plate 360 and follow-up unit 368, helical spring 362 is being set, so, follow-up unit 368 continues rising while overcoming the motive force of helical spring 362.Accompany with it, the follower hand side press parts 352 that are attached at follow-up unit 368 tops also rise, and elect the spring hand side press parts 354 that contact with follower hand side press parts 352.Thus, the conveying in the spring hand side press parts 354 election insertion grooves 355 is moved conveying torsion bar 344 with an end of torsion bar 344 to the top of pressurization roll shaft 312, and releasing is to the motive force of pressurization roll shaft 312.Thus, the promotion that thing 100 is carried usefulness torsion bar 344 at the throughput direction timing from 312 releasings of pressurization roll shaft can be recorded.This state is a holding state shown in Figure 11, to tape deck 10 insert be recorded thing 100 after, backer roll 310 and conveying roller 324 clampings are recorded thing 100 rotations, will be recorded thing 100 and be delivered to correcting plate 360 and contact correction.

After finishing the correction that is recorded thing 100 under the state shown in Figure 13, utilize above-mentioned driving mechanism, cam 390 drives along the direction of arrow rotation of dotted line shown in Figure 13.Cam 390 is after direction of arrow rotation, and pin 398 descends with respect to cam 390 along cam path 392.Thus, follow-up unit 368 descends with respect to body 11.At this moment, at first, because the follower hand side press parts 352 that constitute one with correcting plate 360 descend, so the spring hand side press parts 354 that contact with follower hand side press parts 352 also descend.The conveying that spring hand side press parts 354 are elected descends downwards with an end of torsion bar 344, carries with torsion bar 344 and inserts once more in the groove 314 of pressurization roll shaft 312, promotes pressurization roll shaft 312 downwards.As Fig. 9 and shown in Figure 10, carry with torsion bar 344 and in the V-type groove 314 that is arranged at pressurization roll shaft 312, promote pressurization roll shaft 312, so leave, also can all promote pressurization roll shaft 312 in roughly the same position even pressurize roll shaft 312 temporary transient risings at every turn.And,, drive pressurization roll shaft 312 1 edges and promote pressurization roll shaft 312 perpendicular to the direction of rotating shaft on one side also can rotate even when rotation drives pressurization roll shaft 312.

And by the direction of arrow rotation of cam 390 along dotted line, follow-up unit 368 further descends, and accompanies with it, and correcting plate 360 also descends and avoids from the carrying path that is recorded thing 100, is returned to state shown in Figure 12.

Figure 14 and Figure 15 are the cutaway views that back pressurization part 302 usefulness are represented perpendicular to the plane cut-out of rotating shaft.Figure 14 cuts off with the plane of passing groove 314, and Figure 15 cuts off with the plane of the shaft supporting part 332 that passes afterframe 330.In addition, the backer roll unit of Figure 14 and back pressurization part 302 shown in Figure 15 has the formation identical with the backer roll unit 304 of preceding pressurization part 300, so use the symbol description identical with backer roll unit 304.

As Figure 14 and shown in Figure 15, back pressurization part 302 has: backer roll unit 304, rotate the afterframe 330 that the earth's axis freely supports backer roll unit 304, with backer roll unit 304 towards being recorded the pushing part 334 that thing 100 promotes downwards.On afterframe 330, the shaft supporting part 332 of the shape with U font is being set.In this shaft supporting part 332, insert pressurization roll shaft 312, and rotatably supporting pressurization roll shaft 312.By 304 of backer roll unit are supported on the shaft supporting part 332, the 304 one rotation of backer roll unit is driven.

Pushing part 334 is metal wires, promotes backer roll unit 304 towards being recorded thing 100 downwards in V-type groove 314 always.Because pressurization roll shaft 312 is formed by resin, pushing part 334 is formed by metal, even so 312 rotations of pressurization roll shaft are slided with respect to pressurization roll shaft 312 by pushing part 334, pushing part 334 also can promote pressurization roll shaft 312 more reliably on perpendicular to the direction of rotating shaft.So, compare with the situation of pressurization roll shaft 312 that adopts helical spring and push the both sides of each backer roll 310 by the sleeve pipe that helical spring promotes, can reduce to push the mechanism of backer roll unit 304.

Figure 16 is the partial rear view that the action that is recorded thing 100 is carried in preceding pressurization part 300 of expression and 320 clampings of preceding delivery section.In addition, because carrying when being recorded thing 100, back pressurization part 302 and back delivery section 322 also carry out same action, so omit its explanation.

As shown in figure 16, being recorded thing 100 is configured between backer roll unit 304 and the preceding delivery section 320 the backer roll 310 corresponding to the width that is recorded thing 100 in the backer roll unit, back 304 and just rides against and be recorded on the thing 100.Under this state, by the rotating shaft of delivery section 320 before the rotation driving, transmit gear 321 and pressure side transmission gear 311 via conveyor side, backer roll unit 304 is driven in rotation.Thus, not only be recorded under the situation that thing 100 has the narrowest contemplated width or the wideest width, and have under the situation of any width, backer roll 310 also can be taken to come to and be recorded on the thing 100, with backer roll unit 304 integral body not with respect to being recorded the state that thing 100 tilts, and preceding delivery section 320 between clamping be recorded thing 100, be recorded thing 100 thereby correctly carry.Particularly in a pair of backer roll 310, even the side in the backer roll 310 takes lean on, pushing part 340 also can promote two sides' backer roll 310 equably.And, because the universal joint 370 in the backer roll unit 304 is not directly promoted, be not subjected to the power of radial direction, so under the situation that makes it to rotate in that backer roll unit 304 is applied driving force, backer roll unit 304 can not rock ground rotation smoothly, can suppress to be recorded the vibration of thing 100, improve the precision of record.

Figure 17 will amplify the amplification view of representing near the platen portion among Fig. 4 50, and Figure 18 is with the part of Figure 17 horizontal plane cut-out of being represented by X and the cutaway view of observing from above.In addition, the section of Figure 17 is in inboard (left side among Figure 18) than the section of Fig. 4.

As Figure 17 and shown in Figure 180, platen portion 50 has: the platen 500 that is arranged on record head 200 belows, elect the support spring 550 that supports platen 500 from the below, on the direction that record head 200 moves back and forth, be arranged on the platen limitation in height portion 560 of the height upper limit of the position identical, restriction platen 500 with support spring 550, guide the platen guide member 532,534 that moves of the above-below direction of platen 500, be arranged on the vibration absorption component 540 of platen 500 belows.On record head 200, rotate the roller that is installed with freely as gap holding part 220 with respect to record head 200.

Platen 500 has: the tabular platen body 510 that extends on the moving direction of record head 200, a pair of platen foot 520 of extending towards the downstream of the throughput direction that is recorded thing 100 below platen body 510.Platen body 510 and platen foot 520 are for example by with the rubber-like resin injection molding and integrally formed.The two ends of the moving direction of the record head 200 in platen body 510 also are being provided with pin 515,516 outstanding laterally on the moving direction of record head 200.

Platen body 510 has: with the top smooth top 512 of record head 200 subtends, and the width bottom 514 narrower than top 512 that is recorded the throughput direction of thing 100.Thus, the cross section of platen body 510 has the shape of umbrella as shown in figure 17.Gap holding part 220 is on top 512 and be transported to when being recorded on the thing 100 above this rotate, and 512 length direction moves along top for gap holding part 220 and record head 200.At this moment, gap holding part 220 directly or by be recorded thing 100 push downwards top 512 above, thereby keep being recorded gap between thing 100 and the record head 200.Platen foot 520 is by contacting with platen limitation in height described later portion 560, limits the upper limit of the height of the platen 500 that supported spring 550 elects.

Platen guide member 532,534 is arranged on the two ends of the direction that the record head 200 in the platen 500 moves back and forth, and holds up to vertical direction from body 11.Above-mentioned platen guide member 532,534 has guiding slot part 533,535 in vertical direction respectively.By the pin 515 of insertion platen 500 in guiding slot part 533, in guiding slot part 535, insert the pin 516 of platen 500 simultaneously, guiding slot part 533,535 guides moving up and down of platens 500.And, the bottom surface by platen guide member 532,534 with sell 515,516 and contact the lower limit of the height of restriction platen 500.And, set the height of bottom surface, even make and be recorded under the situation that thing 100 is pressed by contemplated be used to write down the thickest at platen 500, pin 515,516 does not contact with the bottom surface of platen guide member 532,534 yet.

Vibration absorption component 540 for example has sound absorption properties by sponge etc. and flexible material forms, mode with the part of the below of the bottom 514 that covers platen 500 and side is being arranged on the throughput direction that is recorded thing 100 between correcting plate 360 and the back delivery section 322.Vibration absorption component 540 closely contacts with the platen foot 520 of platen 500, and from the throughput direction both sides that are recorded thing 100 it is carried out clamping.And vibration absorption component 540 promotes platen 500 to platen guide member 532,534.In Figure 17 and embodiment shown in Figure 180, the upstream side of the throughput direction that is recorded thing 100 of vibration absorption component 540, on the direction of throughput direction, the bottom 514 of inserting platen 500 with the state of the flattening that doubles than the downstream.Thus, in vibration absorption component 540, stronger to the motive force that the bottom 514 of platen 500 applies than the motive force that applies from the downstream from the upstream side of throughput direction.So platen 500 is whole moving by thrusters downstream, the pin 515,516 of platen 500 is respectively by by to the sidewall in the downstream that is recorded thing 100 of guiding slot part 533,535.Thus, on the direction vertical with the above-below direction of platen 500 vibrations, vibration absorption component 540 can promote platen 500, and absorbs the vibration of platen 500 more reliably.

Here, below the top 512 of platen 500 513 and above the vibration absorption component 540 between 542, be provided with the little clearance G of mobile range that moves along the vertical direction than platen 500.Thus, at the amount of movement up and down of platen 500 hour, absorb the vibration of vibration absorption component 540 by the motive force of the direction vertical with the direction of platen 500 vibrations.And when the amount of movement about platen 500 was big, vibration absorption component 540 contacted with the top 512 of platen 500, also absorbs the vibration of platen 500 on above-below direction.So platen 500 can be followed pushing of record head 200 downwards, the vibration of platen 500 afterwards can be absorbed more reliably by vibration absorption component 540.

Figure 19 and Figure 20 are the synoptic diagrams of explanation state of platen 500 bendings when being pushed downwards by gap holding part 220.Figure 19 represents that record head 200 is in the state near the position of readiness place, and Figure 20 represents that record head 200 is positioned at the state of the approximate centre position that moves back and forth.In addition, the arrow among the figure is represented the position of platen 500 by platen limitation in height portion 560 maximum height limits.

With Figure 17～formation shown in Figure 20 the action of platen portion 50 is described.At first, after delivery section 30 will be proofreaied and correct on throughput direction be recorded above top 512 smooth that thing 100 is transported to platen 500 on.Then, by driving synchronous belt 250 described later, 230 guiding of record head balladeur train are moved on the record head leading axle 260 that is provided with along the length direction on body top 16 by carriage motor 240.Thus, record head balladeur train 230 moving recording head 200 and gap holding part 220 on the length direction of platen 500.In this case, be not loaded with the zone that is recorded thing 100 on the top 512 of platen 500, gap holding part 220 is directly rotated on top 512.In addition, be loaded with the zone that is recorded thing 100 on the top 512 of platen 500, gap holding part 220 rides over and is recorded on the thing 100 and rotates being recorded on the thing 100, thus gap holding part 220 by be recorded thing 100 push platen 500 top 512 above.Thus, gap holding part 220 keeps desirable gap being recorded on the top 512 that is arranged at platen 500 between thing 100 and the record head 200.Even the state that directly rotates from the top 512 in gap holding part 220 at platen 500, be recorded on the thing 100 and push sharp under the situation of platen 500 by riding over, the frictional force that bottom 514 by platen 500 contacts with vibration absorption component 540 and the pin 515,516 of platen 500 are crushed on the slip load on the sidewall in the downstream that is recorded thing 100 in the guiding slot part 533,535 respectively, also can the decay vibration of platen 500 absorbs the vibration of platen 500 rapidly and reliably.

As mentioned above, gap holding part 220 is being recorded rotation on the thing 100, be recorded between thing 100 and the record head 200 keep desirable gap in, the colour band of record head 200 by ribbon cartridge 60 impacts many one metal wires and measuring point being recorded on the thing 100, thereby at the record that is recorded thing 100 enterprising style of writing words etc.In the present embodiment, vibration absorption component 540 is by on the bottom 514 of platen 500, so even be delivered under the situation of platen 500 to the vibration that is recorded on the thing 100 impacting wire, also can absorb the vibration of platen 500.

As Figure 19 and shown in Figure 20, elect support spring 550 that supports platen 500 and the platen limitation in height portion 560 that limits the height of platen 500 from the below, be arranged on same position in the longitudinal direction.Platen 500 has elasticity as mentioned above, pushes downwards by being recorded thing 100, and is crooked like that shown in the dotted line among the figure.But, for convenience of explanation bending is exaggerated and is dotted.In addition, the dotted line among the figure will be explained below.

Figure 21 is the side view of the observed platen 500 of direction that moves back and forth from record head 200.Platen 500 has platen body 510 and platen foot 520 as mentioned above.Platen foot 520 have from platen body 510 two to the vertical portions 522 that vertical lower is extended, and from the lower end of vertical portion 522 to the horizontally extending horizontal part 524 in the downstream of the throughput direction that is recorded thing 100, be the L font.Horizontal part 524 top 525 contacts by the contact site 564 with platen limitation in height described later portion 560, and restriction utilizes the height upper limit of the platen 500 that support spring 550 elects.

Figure 22 is the oblique view of platen limitation in height portion 560.Platen limitation in height portion 560 has: with the flat spring-loaded portion 562 of the following end in contact of the support spring 550 of electing platen 500, outstanding in spring-loaded portion 562, insert in the support spring 550 and in the springlock bonding part 563 of above-below direction guiding and lock support spring 550, be arranged on the contact site 564 of the conveyance direction downstream side that is recorded thing 100 than springlock bonding part 563, the axial region 568 that extends on one distolateral (right side among the figure) of the direction that moves back and forth along record head 200 of platen limitation in height portion 560, along the throughput direction that is recorded thing 100.

It is following 565 that contact site 564 has, below this 565 and spring-loaded portion 562 between have the gap and be positioned at the position higher than spring-loaded portion 562.Contact site 564 is provided with and connects this contact site 564, and the slotted hole of growing on the direction that moves back and forth of record head 200 566.And, in platen limitation in height portion 560, be provided with screwed hole 567 away from the position of axial region 568 than slotted hole 566.

Figure 23～Figure 26 is the synoptic diagram of explanation platen limitation in height portion 560 and Height Adjustment portion 570.Figure 23 is near the oblique view the observed platen limitation in height of the throughput direction that is recorded thing 100 portion 560.Figure 24 uses the part of Figure 23 perpendicular to the plane of the moving direction of record head 200 to cut the profile of representing open.Figure 25 cuts the part of Figure 24 open represent cutaway view with section A.Figure 26 cuts the part of Figure 24 open represent cutaway view with cross section B.

As shown in figure 23, the spring-loaded portion 562 of platen limitation in height portion 560, by with the following end in contact of support spring 550, supported spring 550.Thus, support spring 550 is elected platen 500 with respect to platen limitation in height portion 560 towards record head 200.In addition, the contact site 564 of platen limitation in height portion 560 following 565, by contacting with top 525 of the horizontal part 524 of the platen foot 520 of platen limitation in height portion 560, restriction platen foot 520 is moved upward.Thus, the height upper limit of the platen 500 of supported spring 550 elections of platen limitation in height portion 560 restrictions.And, in contact site 564, below insertion horizontal part 524, be provided with the breakthrough part 569 of through hole with the rectangle that connects to body 11.Thus, under the situation that platen 500 is pushed by gap holding part 220, the platen foot 520 of platen 500 can keep out of the way in this breakthrough part 569.

The axial region 568 of platen limitation in height portion 560 rotates the earth's axis freely and is supported and fixed on limitation in height portion maintaining part 580 on the body 11.Thus, platen limitation in height portion 560 is that rotate at the center with axial region 568, thereby can adjust the spring-loaded portion 562 that is arranged in the platen limitation in height portion 560 and the height with respect to body 11 of contact site 564.

As Figure 24～shown in Figure 26, in the slotted hole 566 of the contact site 564 of platen limitation in height portion 560, and have between the contact site 564 to be inserted with gap and push screw 574, the top of following and contact site 564 of pushing the head of screw of screw 574 contacts, and the leading section of pushing screw 574 is screwed in the screwed hole 576 that is arranged on the body 11.Thus, push screw 574 and push platen limitation in height portion 560, the height upper limit of regulation platen limitation in height portion 560 with respect to body 11.In addition, be screwed in the screwed hole 567 of platen limitation in height portion 560 and elect screw 572, the front end of electing screw 572 contacts with body 11.Thus, elect screw 572 and elect platen limitation in height portion 560 with respect to body 11, the height lower limit of regulation platen limitation in height portion 560.Above-mentioned election screw 572 and push the example that screw 574 is the Height Adjustment portions 570 among the present invention.

In the above-described configuration, by electing screw 572 to the rotation of the direction that is pressed into towards platen limitation in height portion 560 when, to the direction rotary push screw 574 that floats from body 11, thus following 565 the moving up of the contact site 564 of platen limitation in height portion 560.Thus, the height upper limit of platen 500 moves up, and the platen 500 the when gap holding part 220 of record head 200 does not contact uprises with respect to the height of record head 200.In addition, by electing screw 572 to the direction of floating rotation when from platen limitation in height portion 560, to the direction rotary push screw 574 that is pressed into towards body 11, thus following 565 the moving down of the contact site 564 of platen limitation in height portion 560.Thus, the height upper limit of platen 500 moves down, and the platen 500 the when gap holding part 220 of record head 200 does not contact is with respect to the height step-down of record head 200.By aforesaid operations, Height Adjustment portion 570 can adjust and stationary platen limitation in height portion 560 with respect to the height of record head 200.In this case, even change the height upper limit of platen 500 with respect to record head 200, the spring-loaded portion 562 of platen limitation in height portion 560 and the relative position of platen 500 do not change yet, so the motive force that the support spring 550 that is arranged between spring-loaded portion 562 and the platen 500 is elected platen 500 roughly can be kept certain.

As shown in figure 25, electing screw 572 is provided with away from axial region 568 than pushing screw 574.Thus, pushing platen 500 downwards during to the downward power of platen limitation in height portion 560 effect by gap holding part 220, clip the axial region 568 of pushing screw 574 and elect screw 572 brace table plate height restriction stably portion 560, so can prevent 560 distortion of platen limitation in height portion or destruction.

As shown in figure 26, on the direction that record head 200 moves back and forth, support spring 550 and platen limitation in height portion 560 are arranged on same position.So, under the situation that platen 500 is not pushed by gap holding part 220, can reduce the bending moment that between position on the platen 500, that elect by support spring 550 and position, produces, can suppress platen 500 and produce plastic deformation and creep in time by platen limitation in height portion 560 maximum height limits.

And, as shown in figure 24, push screw 574 be arranged on the throughput direction that is recorded thing 100 contact site 564 near.Thus, can reduce in platen limitation in height portion 560 bending moment that produces by between the contact site 564 of pushing position that screw 574 pushes and electing by platen foot 520, can suppress platen limitation in height portion 560 and produce plastic deformation and creep in time.

Figure 27 is when illustrating on gap holding part 220 moves to platen 500, the synoptic diagram of the amount of platen 500 displacements.In Figure 27, at supposition platen 500 is under the situation of rigid body, when gap holding part 220 was pushed platen 500 downwards with certain power, the position of being pushed by gap holding part 220 of platen 500 was by the support spring 550 and amount of displacement is expressed as " based on the displacement of spring ".And, in the figure, replace with rigid body in supposition under the situation of support spring 550 and support platen 500, when gap holding part 220 is pushed platen 500 downwards with certain power, the amount of displacement is expressed as " based on flexible displacement " by the strain of platen 500 in the position of being pushed by gap holding part 220 of platen 500.

When gap holding part 220 is pushed platen 500 downwards with certain power, the amount of its position displacement be above-mentioned based on spring displacement and based on flexible displacement and.As shown in figure 27, between a pair of support spring 550, platen 500 based on the displacement of spring and based on flexible displacement with certain substantially.So it is gap holding part 220 is pushed the required power of platen 500 with certain displacement, certain substantially between a pair of support spring 550.Thus, when gap holding part 220 moves back and forth, can stably push platen 500 on platen 500.

Figure 28 and Figure 29 be explanation in comparative example 1, gap holding part 220 synoptic diagram of the amount of platen 500 displacements when mobile on platen 500.And, give identical mark for the formation identical, and omit its explanation with Figure 19 and Figure 20.In Figure 28 and comparative example 1 shown in Figure 29, different with Figure 19 and present embodiment shown in Figure 20, platen limitation in height portion 560 is arranged on the two ends of the length direction of platen 500, limits the height upper limit of platen 500 by the plate 500 of presenting a theatrical performance as the last item on a programme from the top.

In this comparative example 1, be near the state at position of readiness place and be positioned under the situation of the approximate centre that moves back and forth at record head 200, platen 500 is respectively shown in the dotted line of Figure 28 and Figure 29 and crooked.But, in above-mentioned figure, for convenience of explanation the bending exaggeration is represented.In Figure 29, platen 500 is pushed and crooked downwards by gap holding part 220 near central authorities, and the supported spring 550 in its both sides is elected and bending upward, and two ends are crooked downwards.In addition, even do not push in gap holding part 220 under the state of platen 500, because it is distolateral that the position of also being elected than supported spring 550 by the position of platen limitation in height portion 560 maximum height limits relies on, so can be created in crooked moment on the platen 500 whole directions protruding upward.As mentioned above, the platen 500 of comparative example 1 might produce plastic deformation in time, or produces creep.In addition, in order to compare, in Figure 19 and Figure 20, represent the bending of this comparative example 1 with dotted line.

Figure 30 and Figure 31 be explanation in comparative example 2, gap holding part 220 synoptic diagram of the amount of platen 500 displacements when mobile on platen 500.In Figure 30 and comparative example 2 shown in Figure 31, different with Figure 19 and present embodiment shown in Figure 20, platen limitation in height portion 560 in the longitudinal direction than support spring 550 near the center side settings.

In this comparative example 2, be near the state at position of readiness place and be positioned under the situation of the approximate centre that moves back and forth at record head 200, platen 500 is respectively shown in the dotted line of Figure 30 and Figure 31 and crooked.But, in above-mentioned figure, for convenience of explanation the bending exaggeration is represented.And, in order to compare, the bending of the platen in the present embodiment of Figure 19 and Figure 20 500 is dotted in Figure 30 and Figure 31 respectively.For example, as shown in figure 30, the right-hand member that is positioned at when left side platen 500 at record head 200 is unusual earth deformation upward.And, even do not push in gap holding part 220 under the state of platen 500, because the position by platen limitation in height portion 560 maximum height limits also relies on center side than the position that supported spring 550 is elected, so can be created in crooked moment on the platen 500 whole directions of protruding downwards.As mentioned above, the platen 500 of comparative example 2 also might produce plastic deformation in time, or produces creep.

Compare with comparative example 1 and comparative example 2, in the present embodiment, on the length direction of platen 500 with the same position that is arranged on of support spring 550 and platen limitation in height portion 560, so crooked little when being pushed by gap holding part 220.And, even under the situation of not pushed by gap holding part 220, also can be on platen 500, reduce the bending moment that between position of electing and position, produces, can suppress platen 500 and produce plastic deformation and creep in time by platen limitation in height portion 560 maximum height limits by support spring 550.

And, in the present embodiment, also can make support spring 550 be positioned at the below of gap holding part 220 in the position of record head 200 standbies.Thus, even when record head 200 standbies, push platen 500 downwards by gap holding part 220, also can reduce the bending moment that between position of electing and position, produces, can suppress platen 500 and produce plastic deformation and creep in time by gap holding part 220 maximum height limits by support spring 550.

Figure 33 is the front view of colour band winder unit 600.Figure 34 is the oblique view of planet bar 620 and planetary gear 700.Figure 35 is the oblique view after in colour band winder unit 600 planet bar 620 and planetary gear 700 being pulled down.Figure 36 is the backsight oblique view from the observed colour band winder unit 600 in the downstream of the throughput direction that is recorded thing 100.In addition, in Figure 34, for convenience of explanation and the state that the part of planetary drive gear 710 is cut in expression open, and the state that floats from planetary drive gear 710 of expression planet driven gear 730.

As shown in figure 33, colour band winder unit 600 has: be arranged on rotating shaft 242 the axle on sun gear 612, planet bar 620 with rotating shaft 242 engagements, be arranged on the planetary gear 700 on the planet bar 620, the just commentaries on classics driven gear 630 and the counter-rotating driven gear 640 that with planetary gear 700 engagements the time, rotate in company with planetary gear 700, with the idler gear 650 of counter-rotating driven gear 640 engagements, always with the above-mentioned colour band wireline reel 660 that just changes driven gear 630 and idler gear 650 engagements.Colour band winder unit 600 also has accommodates above-mentioned planet bar 620, planetary gear 700, just changes the housing 670 of driven gear 630, counter-rotating driven gear 640, idler gear 650 and colour band wireline reel 660.

Sun gear 612 is to be wholely set with belt drives wheel 610 and to take turns the little gear of 610 diameters than belt drives, is positioned on the direction of principal axis of rotating shaft 242 than the sides of belt drives wheel 610 near carriage motors 240.Thus, sun gear 612 is just changeing along with rotating shaft 242 or is reversing and just change or reverse.

Use Figure 33, the transmission and the direction of rotation of the rotary driving force of the tape wrapping unit 600 of checking colors describe.Rotating shaft 242 is just changeing (direction of the dotted arrow among Figure 33), and the sun gear 612 that then is arranged on the rotating shaft 242 also just changes.Accompany with it, planet bar 620 moves along the dotted arrow direction, and the planetary gear 700 that is arranged on the planet bar 620 revolves round the sun on sun gear 612, thus planetary gear 700 with just changeing driven gear 630 engagements.Under this state, and then just changeing by sun gear 612, planetary gear 700 also reverses in company with its rotation, is just changeing that driven gear 630 rotates in company with this planetary gear 700 and along the direction rotation of the dotted arrow among the figure.Along with this rotation of just changeing driven gear 630, the rotation of the direction of the dotted arrow of colour band wireline reel 660 in figure.

In addition, rotating shaft 242 counter-rotatings (direction of the solid arrow among Figure 33), the sun gear 612 that then is arranged on the rotating shaft 242 also reverses.Accompany with it, planet bar 620 moves along the solid arrow direction, and the planetary gear 700 that is arranged on the planet bar 620 revolves round the sun on sun gear 612, thus planetary gear 700 and 640 engagements of counter-rotating driven gear.Under this state, and then by sun gear 612 counter-rotatings, planetary gear 700 is also just changeing in company with its rotation, and counter-rotating driven gear 640 rotates in company with this planetary gear 700 and rotates along the direction of the solid arrow among the figure.Along with this rotation of counter-rotating driven gear 640, the direction rotation of the solid line of idler gear 650 in figure.Along with this rotation of idler gear 650, the direction rotation of the solid arrow of colour band wireline reel 660 in figure.

As shown in figure 34, planet bar 620 has integral body and is roughly tabular body 622, is equipped with rotating shaft 720 near an end of body 622, keeps planetary gear 700.At the other end of body 622, be provided with the otch 623 with rotating shaft 242 concentric circles arcuations of being with rotating shaft 242 engagement, and be arranged on the protuberance 624 around this otch 623.Protuberance 624 extends towards carriage motor 240 along the direction of principal axis of rotating shaft 242.Thus, planet bar 620 keeps the distance of sun gear 612 and planetary gear 700.As shown in figure 36, the otch 623 of planet bar 620 has circular-arc along with what excise towards planetary gear 700 sides from one side of planet bar 620 more and more deeply.Thus, though at planetary gear 700 under the situation of the pressure that just changes driven gear 630 and counter-rotating driven gear 640 and meshed, the otch 623 of planet bar 620 also can contact with rotating shaft 242, thereby can prevent that planet bar 620 from coming off from rotating shaft 242.

As shown in figure 34, planetary gear 700 has: be arranged on the planet bar 620, with sun gear 612 engagements and in company with the planetary drive gear 710 of sun gear 612 rotations, be arranged on the coaxial planet driven gear 730 of going up, rotating with planetary drive gear 710 in company with planetary drive gear 710, with the push mechanism 740 that planetary drive gear 710 and planet driven gear 730 promote to approaching mutually direction, connect the rotating shaft 720 of planetary drive gear 710, planet driven gear 730 and planet bar 620.

Planetary drive gear 710 has approximate discoid shape, and periphery is provided with the tooth 712 with the tooth engagement of sun gear 612.At the center of planet driven wheel 710, be provided with the through hole of the bottom of admitting rotating shaft 720.In the outside of this through hole, the hole that has with respect to a plurality of inclined-planes 714 of circumferencial direction and direction of principal axis inclination is set.

Planet driven gear 730 has the shape of the approximate circle tubular littler than planetary drive gear 710 diameters.On the top of the periphery of planet driven gear 730, be provided with and the tooth 732 that is just changeing driven gear 630 and 640 engagements of counter-rotating driven gear.In the bottom of the periphery of planet driven gear 730, be provided with a plurality of inclined-planes 734 that tilt with respect to circumferencial direction and direction of principal axis.Push mechanism 740 promotes planet driven gear 730 to planetary drive gear 710, thereby under general state, planetary drive gear 710 and planet driven gear 730 are meshing with each other at 714,734 places, above-mentioned a plurality of inclined-plane.

Rotating shaft 720 has approximate columned shape, and the upper end has flange 722.At 724 places, lower end of rotating shaft 720, be provided with not shown groove around axle, in this groove, be inserted with baffle ring.Thus, the lower end 724 of rotating shaft 720 can not deviate from from planet bar 620.

Push mechanism 740 contacts with the flange 722 of rotating shaft 720, when planetary drive gear 710 promotes planet driven gear 730, promote planetary drive gears 710 to planet bar 620.Thus, push mechanism 740 applies load torque with respect to planet bar 620 to planetary drive gear 710, so will be delivered to planet bar 620 from the driving force that sun gear 612 is applied to planetary drive gear 710, and this driving force will be switched to the driving force of rotating planet bar 620.One example of push mechanism 740 is a helical spring.

In the above-described configuration, applying under the situation of the torque below a reference value planetary drive gear 710 and the rotation of planet driven gear 730 one between planet driven wheel 710 and the planet driven gear 730.In addition, applying between planet driven wheel 710 and the planet driven gear 730 under the situation of the torque more than a reference value, overcome the motive force of push mechanism 740, inclined-plane 734 along engagement on planet driven wheel 710, the inclined-plane 734 of planet driven gear 730 slides.Thus, planet driven gear 730 floats with respect to planetary drive gear 710, rotates freely with respect to planetary drive gear 710.Thus, restriction is applied to the torque on the planet driven gear 730.Thus, in ribbon cartridge 60 the colour band tangle up, when colour band is lockable etc., applying on the planet driven gear 730 under the situation of bigger torque, can prevent 600 breakages of colour band winder unit.

As mentioned above because between the planetary drive gear 710 of planetary gear 700 and planet driven gear 730 torque-limiting, so the mechanism of torque-limiting need be set separately, can reduce number of spare parts outside planetary gear 700.And, because promote planet driven gear 730 by push mechanism 740 according to said sequence, even so under the situation that planet driven gear 730 rotates freely with respect to planetary drive gear 710, also can keep the engagement of planetary drive gear 710 and sun gear 612.And, can pass through the torque of the inclination setting on inclined-plane 714,734 as a reference value.For example, under the situation that is provided with axially the less inclined-plane 714,734 of the inclination of erectting, planet driven gear 730 freely begins the torque of rotating with respect to planetary drive gear 710 a reference value becomes big.In addition, under the situation that is provided with the bigger inclined-plane of axially mild inclination 714,734, the said reference value of torque diminishes.And, in the present embodiment, for the direction of rotation of planetary drive gear 710 and planet driven gear 730, the inclination symmetry on inclined-plane 714,734, so, can make a reference value of torque identical under the situation that planet driven wheel 710 and planet driven gear 730 are just changeing and under the situation of counter-rotating.It should be noted that in addition, asymmetric by the inclination that makes inclined-plane 714,734, under the situation that planet driven wheel 710 and planet driven gear 730 are just changeing and under the situation of counter-rotating, can set a reference value of torque for different value.

As shown in figure 35, just changeing driven gear 630 and having: with the large diameter gear portion 632 of planet driven gear 730 engagement, above large diameter gear portion 632 with this large diameter gear portion 632 integrally formed the and diameter small-diameter gear portion 634 littler than large diameter gear portion 632.Large diameter gear portion 632, planet bar 620 rotates around rotating shaft 242 when just changeing by switching to from counter-rotating at sun gear 612, and with 730 engagements of planet driven gear.In addition, under the situation of sun gear 612 counter-rotatings, large diameter gear portion 632 breaks away from the engagement with planet driven gear 730.Small-diameter gear portion 634 meshes with colour band wireline reel 660 always.Thereby large diameter gear portion 632 is in company with 730 rotations of planet driven gear, and then small-diameter gear portion 634 just transmits this rotary driving force to colour band wireline reel 660, rotation colour band wireline reel 660.

Similarly, counter-rotating driven gear 640 has: with the large diameter gear portion 642 of planet driven gear 730 engagement, above large diameter gear portion 642 with this large diameter gear portion 642 integrally formed the and diameter small-diameter gear portion 644 littler than large diameter gear portion 642.Counter-rotating driven gear 640, by switching to when counter-rotating planet bar 620 and rotate from just changeing around rotating shaft 242 at sun gear 612, and with 730 engagements of planet driven gear.In addition, under the situation that sun gear 612 is just changeing, large diameter gear portion 642 breaks away from the engagement with planet driven gear 730.Small-diameter gear portion 644 meshes with idler gear 650 always.And idler gear 650 meshes with colour band wireline reel 660 always.Thereby large diameter gear portion 642 is in company with planet driven gear 730 rotation, and then small-diameter gear portion 644 just transmits this rotary driving force to idler gear 650, and idler gear 650 and then this rotary driving force transmitted to colour band wireline reel 660 rotates colour band wireline reel 660.

Here, just changeing the large diameter gear portion 632 of driven gear 630 and the large diameter gear portion 642 of counter-rotating driven gear 640, though have planet driven gear 730 overcome the motive force of push mechanism 740 and under the state that floats from planetary drive gear 710 also with the axial height of planet driven gear 730 engagements.Thus, even in the torque that is subjected to more than a reference value, under the situation that planet driven gear 730 floats from planetary drive gear 710, can prevent that also planet driven gear 730 and the engagement of just changeing driven gear 630 or counter-rotating driven gear 640 from throwing off.So the bottom that can successfully be returned to planet driven gear 730 enters position planetary drive gear 710, original.

Colour band wireline reel 660 has always the large diameter gear portion 662 with small-diameter gear portion 634 that just changes driven gear 630 and idler gear 650 engagements, and the small-diameter gear portion 664 that insert in ribbon cartridge 60, with the reel of ribbon cartridge 60 combine littler than large diameter gear portion's 662 diameters.Thus, as mentioned above, sun gear 612 bears when just changeing from the rotary driving force that just changes driven gear 630, bears the rotary driving force from idler gear 650 when counter-rotating, and colour band wireline reel 660 all rotates to equidirectional in any case.

As Figure 34 and shown in Figure 36, the planet rod bearing 672 of housing 670 has the U notched cut that contacts with the protuberance 624 of planet bar 620.Thus, planet bar 620 can rotate with respect to housing 670 around rotating shaft 242 smooth and reliablely.And, because the otch of planet bar 620 623 is circular-arc,, can easily assemble colour band winder unit 600 on planet bar 620 so compare with the situation that through hole is set and inserts rotating shaft 242.And easily dismounting sun gear 612 and planet bar 620 when colour band winder unit 600 breaks down etc., can be changed colour band winder unit 600 thus easily.And, because it is 610 integrally formed that sun gear 612 and belt drives are taken turns, so do not need to be provided with separately with 610 engagements of belt drives wheel, from the sun gear 612 of belt drives wheel 610 transmission rotary driving forces, can reduce the number of spare parts of colour band winder unit 600.

More than, according to present embodiment, promote to push backer roll unit 304 with 2 different stages of power to being recorded thing 100 with carrying by proofreading and correct with torsion bar 344 with torsion bar 342, so compare with the situation of the sleeve pipe that is promoted by helical spring with using 2 helical springs, can reduce to promote the mechanism of backer roll unit 304.

More than, utilize embodiment to describe the present invention, but technical scope of the present invention be can't help the scope that above-mentioned embodiment puts down in writing and is limited.It will be apparent to those skilled in the art that can be to various changes or the improvement in addition of above-mentioned embodiment.The mode that has applied this change or improvement also can be included in the technical scope of the present invention, and this point can be known by the record of technical scheme of the present invention and learns.
