Description
Technical field
The present invention relates to by spraying ink droplet from record head the ink-jet recording apparatus of document image on record-paper, detailed says, relates to the ink-jet recording apparatus that is provided with movable support portion on the impression flat board.
Background technology
Ink-jet recording apparatus has the record head that is provided with a plurality of nozzles side by side.The record-paper of document image is transported to the below of this record head.Record head moves to main scanning direction (direction vertical with the throughput direction of record-paper), and sprays ink droplet in predetermined sequential from said nozzle, thus, and document image on this record-paper.Ink-jet recording apparatus in recent years for example has as photographic printing the function of document image on record-paper.This image record is not provided with blank at the edge of record-paper and carries out, and is called as what is called " boundless record ".
When carrying out boundless record, the edge that record head surmounts record-paper sprays ink till the outside of this record-paper.For example, in the boundless record of record-paper front end and rear end, this record-paper is positioned with respect to this record head so that the part in above-mentioned a plurality of nozzle is configured in the outside at this record-paper edge, thereby spray ink droplet to the impression flat board that is disposed at this record-paper below from this nozzle.This impresses dull and stereotyped, is provided with the groove that extends to main scanning direction at an upper portion thereof, has the ink absorption parts in the inside of this groove.Therefore, ink droplet is absorbed by above-mentioned ink absorption parts.Therefore, this record-paper on the whole document image and can not produce at the edge of record-paper blank, and can be because of not being ejected into make dirty the reverse side (for example with reference to patent documentation 1) of this record-paper of ink on the impression flat board.
In addition, in recent years, ink-jet recording apparatus is required the high speed of image record.In order to realize the high speed of image record, just need to realize the maximization of record head in the prior art.This is because after record head maximized, the nozzle number of arranging on the throughput direction of record-paper increased, and can carry out high-speed record.But in order to carry out above-mentioned boundless record well, the maximization of incident record head must will be located at the width dimensions (size of the throughput direction of record-paper) of the groove on the impression flat board and set greatlyyer.
And when carrying out above-mentioned boundless record, record-paper is configured on the groove of being located in the impression flat board, thus this groove width become big after, this record-paper is with crooked and mode that fall in this groove is out of shape vertically downward.After the such bending of record-paper, the variable in distance on the nozzle of record head and the surface of this record-paper, it is bad to produce record.
In order to address this is that, in the past, in the groove of above-mentioned impression flat board, be provided with paper support device, this paper support device is followed the conveying of record-paper and is rotated.Thus, the record-paper that the sheet support member supporting enters on above-mentioned groove supports the position of this record-paper, moves along the width of above-mentioned groove.Therefore, this record-paper is even when carrying on the groove of above-mentioned impression flat board, also by above-mentioned sheet support member supporting (for example with reference to patent documentation 2, patent documentation 3).
Patent documentation 1: the spy opens the 2000-118058 communique
Patent documentation 2: the spy opens the 2001-80145 communique
Patent documentation 3: the spy opens the 2002-307769 communique
But existing sheet support parts are that (with reference to above-mentioned patent documentation 2) rotated at the center with predetermined rotary middle spindle, so the leading section of sheet support parts (with the part of record-paper contact) separates after the record head side joint is near.Therefore, record-paper always is not supported for parallel with record head.In order to address this problem, can to set the radius of turn of sheet support parts enough big, but will produce the new problem that ink-jet recording apparatus maximizes like this.In addition, it is the circular-arc of center that the face of sheet support member supporting record-paper is formed with above-mentioned rotary middle spindle, and this makes the point that supports record-paper fix, and can't always support the end of the record-paper that transports.That is, the face that so will support record-paper form circular after, record-paper is only supported at the above-mentioned strong point, the position beyond this strong point (zones before and after this strong point) bending, its result, might and above-mentioned same generation record bad.
In addition, in ink-jet recording apparatus, for document image brightly, the distance of the record-paper that transports and the relative position relation of said nozzle, particularly record-paper and nozzle is extremely important.Constant for this distance is kept, need prevent that the record-paper that transports from floating from impressing flat board.The reason that this record-paper floats mainly is the initial deformation (warpage etc.) of the record-paper that transports, the wave inception phenomenon of record-paper in also will considering to write down.For within the specific limits, consider on the impression flat board, to be provided for suppressing the guiding parts that floats of record-paper with the distance limit of record-paper and nozzle.
And ink-jet recording apparatus in recent years has for example function of document image as photographic printing.This image record is not provided with blank at the edge of record-paper, is called as " boundless record ".In addition, with respect to this boundless record, be provided with blank record and be called as " the limit record is arranged ".When the limit record is arranged, general common paper or the bigger thin papers of recycled writing paper equidimension that use the A4 size more, therefore, record-paper easy deformation in the record.Therefore, when the limit record is arranged, by the big distortion that above-mentioned guiding parts prevents record-paper is set.Its result, record-paper can not produce the pollution that produces because of the interference with record head and so-called paperboard etc., has realized the distinct limit record that has.
And when carrying out boundless record, the edge that record head is crossed record-paper sprays ink till the outside of this record-paper.Therefore, when carrying out boundless record, on above-mentioned impression flat board, dispose above-mentioned guiding parts, can hinder distinct boundless record.Promptly, in order to realize the distinct limit record that has, should be on the impression flat board configuration be used to limit record-paper from impressing the dull and stereotyped guiding parts that floats and the distance between record-paper and record head is maintained within a certain range, but when carrying out boundless record, this guiding parts may block from the ink droplet of record head to the record-paper ejection, has the problem that is difficult to carry out distinct boundless record.On the other hand, when carrying out boundless record, general use taken a picture with ground paper such as glossy papers more, is difficult to cause the distortion of record-paper in record.Therefore, when carrying out boundless record, the necessity of above-mentioned guiding parts is lower.
Summary of the invention
First purpose of the present invention is to provide a kind of ink-jet recording apparatus, and it can be by supporting the end of the record-paper transport effectively on the impression flat board, and carry out good boundless record at high speed.Second purpose of the present invention is to provide a kind of ink-jet recording apparatus, and it can have the limit record, and the time can not block to the ink droplet of the edge of record-paper ejection and can carry out distinct image record carrying out boundless record.
According to the present invention, ink-jet recording apparatus is provided, have:
Support the impression flat board of record-paper;
Record head disposes in opposite directions with the impression flat board, is being transported to document image on the record-paper that impresses on the flat board by the ejection ink droplet; With
The above-mentioned record-paper that transports is followed in movable support portion, and it is mobile to slide to this throughput direction on the impression flat board when supporting this record-paper.
The record-paper that is transported on the impression flat board impresses flat support by this.With impression flat board configuration record head opposite to each other, this record head sprays ink droplet when main scanning direction moves.Thus, document image on this record-paper.The record-paper that is transported on the impression flat board is further carried to throughput direction, and this moment, movable support portion is being supported this record-paper and is being slided to this throughput direction.That is, the end of this record-paper is always supported by movable support portion, so can be with respect to this throughput direction bending.Its result, the distance of this record-paper and record head keeps constant.
And then, when this record-paper is carried on the impression flat board, this record-paper is supported in movable support portion, even therefore form the very big groove of width between the first sheet support portion and the second sheet support portion, this record-paper can be not crooked and enter in this groove yet, it is constant that thereby the distance of this record-paper and record head keeps, and realized the high image quality printing.Therefore like this, above-mentioned groove width is set greatlyyer, even record head maximizes, it is whole that above-mentioned groove also can cover the ink-jet zone of this record head, and its result has also realized the high speed of boundless record.
Above-mentioned impression flat board has: framework has the upper surface that extends along above-mentioned throughput direction; The first sheet support portion, the outstanding above-mentioned throughput direction upstream side that is arranged on above-mentioned upper surface; With the second sheet support portion, the outstanding above-mentioned conveyance direction downstream side that is arranged on above-mentioned upper surface, with its with the above-mentioned first sheet support portion between form groove to above-mentioned main scanning direction extension.In addition, above-mentioned movable support portion is set to, and can follow the record-paper of carrying to above-mentioned throughput direction, and the above-mentioned first sheet support portion position adjacent and and the above-mentioned second sheet support portion position adjacent between slide along above-mentioned throughput direction.
At this moment, the record-paper that is transported on the impression flat board is at first supported by the first sheet support portion.And then the second sheet support portion side is carried and be transported to this record-paper in the first sheet support portion.Between the first sheet support portion and the second sheet support portion, form groove.This groove is formed on the low position than the first sheet support portion and the second sheet support portion.Therefore, when carrying out boundless record, the edge that can cross this record-paper sprays ink droplet from record head especially.Crossing the ink droplet of the edge ejection of this record-paper is caught by above-mentioned groove.Therefore, can lay ink absorption parts (being typically the sponge of sheet) in the bottom of this groove.The end of the record-paper of carrying in the above-mentioned first sheet support portion by above-mentioned groove above.At this moment, movable support portion is followed the record-paper that transports and is slided to above-mentioned throughput direction.That is, movable support portion from the main scanning direction with the first sheet support portion position adjacent on main scanning direction, sliding with the second sheet support portion position adjacent, support the above-mentioned record-paper that transports simultaneously.Therefore, the end of this record-paper is always supported by movable support portion, can not enter in the above-mentioned groove.Its result, the distance of this record-paper and record head keeps constant.
The above-mentioned first sheet support portion can have a plurality of first fixing rib, above-mentioned first fixing rib, the outstanding above-mentioned throughput direction upstream side part that is arranged on above-mentioned upper surface, and on above-mentioned main scanning direction, be set up in parallel, the above-mentioned second sheet support portion can have a plurality of second fixing rib, the outstanding above-mentioned conveyance direction downstream side part that is arranged on above-mentioned upper surface of described second fixing rib, and on above-mentioned main scanning direction, be set up in parallel.Above-mentioned movable support portion can have a plurality of movable ribs, described movable rib can slide between the primary importance second place, described primary importance is located between each adjacent on the above-mentioned main scanning direction first fixing rib, and the described second place is located between each adjacent on the above-mentioned main scanning direction second fixing rib.Movable rib is the rib that extends along throughput direction, and its shape can be triangle etc.Like this, the first sheet support portion, the second sheet support portion and movable support portion are made of rib, thereby the contact area of the record-paper and the first sheet support portion, the second sheet support portion and movable support portion is less, so can carry this record-paper swimmingly.And the structure of the first sheet support portion, the second sheet support portion and movable support portion is very simple.
The width of above-mentioned groove can be set to bigger than the ink-jet zone of above-mentioned record head.In addition, should " width of groove " be the width of the throughput direction of record-paper, be the width on the direction (subscan) vertical with main scanning direction.Thus, when record-paper was not configured on the impression flat board, even spray ink droplets from all nozzles of record head, all ink droplets of this ejection also can be sprayed onto on the bottom surface of above-mentioned groove.Therefore, when carrying out boundless record, can record head not carried out complicated control, from all nozzles ejection ink droplets of this record head and carry out the image record in the end of record-paper.In other words, if the width of above-mentioned groove is narrower than the ink-jet zone of above-mentioned record head, then when the front end of record-paper carries out boundless record, must be only from the nozzle ejection ink droplet of the upstream side of record head, follow the conveying of this record-paper and, need carry out complicated control record head successively from the nozzle ejection ink droplet in downstream, but in the present invention, need not the control of this complexity, as above above-mentioned, can be by coming the image record is carried out in the end of record-paper from all nozzle ejection ink droplets.That is,, can carry out boundless record at a high speed about carrying out complicated control from nozzle ejection ink droplet.And then the section shape of said nozzle may not be a circle and may be attached with fine dust at nozzle surface just sometimes, thus ink droplet be not sometimes from nozzle under ejection but to the direction ejection of tilting a little.In this case, because the width of above-mentioned groove is set greatlyyer than the ink-jet zone of record head, so ink droplet can not be attached to the outside of groove.Its result has prevented that the reverse side of record-paper from being besmirched by ink.
Can carry out chamfer machining to the above-mentioned throughput direction upstream side bight of above-mentioned movable support portion.In this constitutes,, also can guide the end of this record-paper swimmingly by the upper surface of movable support portion even when the butt of the throughput direction upstream side bight of the end of the record-paper that has passed through the first sheet support portion and movable support portion.Therefore, can not hinder the conveying smoothly of record-paper because movable support portion is set.
Be provided with movable rib driving mechanism, when it is transported to the above-mentioned throughput direction upstream-side-end of said frame at above-mentioned record-paper, above-mentioned movable rib is configured in above-mentioned primary importance, and make above-mentioned movable rib follow the conveying of above-mentioned record-paper, slide to above-mentioned throughput direction with the state of the end of supporting this record-paper.By this movable rib driving mechanism is set, when record-paper was transported on the impression flat board, movable rib was temporarily met this record-paper to the throughput direction upstream side, and follow this record-paper conveying, supporting the end of this record-paper to this conveyance direction downstream side slip.Thus, the end of this record-paper is always supported by movable support portion, can not enter in the above-mentioned groove.Its result, the distance of this record-paper and record head keep constant effectively.
Above-mentioned movable rib driving mechanism has: input block, slide to above-mentioned main scanning direction under the effect of above-mentioned record head; Swivel plate rotatably is supported on the predetermined oscillation center axle of being located on the said frame, and rotates to predetermined direction according to the slip of above-mentioned input block; And tilting member, its central portion is supported on the predetermined rotary middle spindle of being located on the said frame swingably, and its base end part fastens with the buckling parts of being located on the above-mentioned swivel plate, its leading section is according to the rotation of this swivel plate, with above-mentioned oscillation center axle is the center, move at the above-mentioned throughput direction in imaginary plane upper edge that is parallel to above-mentioned upper surface, above-mentioned movable support portion can be installed on the leading section of above-mentioned tilting member.Above-mentioned record head moves back and forth along main scanning direction, follows the motion of this record head, and input block is along the main scanning direction displacement.Specifically, for example the every reciprocating motion of record head once, this record head pushes above-mentioned input block, thus this input block slides.When this input block slided, swivel plate rotated to predetermined direction.The central portion of tilting member is located on the said frame via the oscillation center axle, and the base end part of tilting member fastens with the buckling parts of being located on the swivel plate, so the rotation of accompanying rotation plate, this tilting member is the center swing with above-mentioned oscillation center axle.At the leading section of this tilting member above-mentioned movable rib is installed, so follow this movable rib of swing of tilting member to slide to above-mentioned throughput direction.
Also can have: rotation restricting unit, limit above-mentioned swivel plate to rotating in the opposite direction with predetermined party, and by making above-mentioned input block slide into predetermined restriction cancellation position, remove this restriction; And spring members, be installed on the above-mentioned swivel plate, accumulate deformation energy with this swivel plate accordingly to the anglec of rotation of above-mentioned predetermined direction.At this moment, above-mentioned input block and rotation restricting unit, formation only makes swivel plate limit its ratchet mechanism to opposite spin to above-mentioned predetermined direction rotation.Therefore, when record head moved back and forth, swivel plate rotated to predetermined direction, and the distortion of above-mentioned spring members, accumulated deformation energy.When sliding into predetermined restriction cancellation position, remove the rotation restriction of above-mentioned swivel plate, allow rotating freely of swivel plate according to the slip of above-mentioned record head, above-mentioned input block.That is, remove the rotation restriction of above-mentioned swivel plate, discharge the deformation energy of accumulating in the above-mentioned spring members, so this swivel plate is to the opposite spin of predetermined direction.
Specifically, above-mentioned movable rib is configured in (central portion of above-mentioned groove) between for example above-mentioned first fixing rib and second fixing rib usually, thereafter, slides along above-mentioned throughput direction corresponding to the reciprocating motion of record head.And as above above-mentioned by removing the rotation restriction of above-mentioned swivel plate, movable rib is configured between above-mentioned first fixing rib and second fixing rib once more.This movable rib in addition, at ordinary times movable rib is being configured between above-mentioned first fixing rib and second fixing rib like this, so when not carrying out above-mentioned boundless record, can be fixed on the position between this first fixing rib and second fixing rib.
Ink-jet recording apparatus of the present invention can have movable support portion driver part.Movable support portion driver part, make the movable support portion of supporting printing medium follow this printing medium and slide to throughput direction, this printing medium is being disposed on the impression flat board below the reciprocating record head of main scanning direction to the throughput direction conveying perpendicular to main scanning direction.This movable support portion driver part can have: the rotation board rotatably is supported on the predetermined rotary middle spindle, and fastens with the buckling parts of being located on the above-mentioned movable support portion; And gathering sill, be located on the buckling surface of buckling parts fastening on this rotation board and above-mentioned movable support portion, stating rotary middle spindle more than the rotation board by this is pivot rotation, and guides the buckling parts of above-mentioned movable support portion between the above-mentioned throughput direction upstream-side-end of above-mentioned impression flat board and above-mentioned conveyance direction downstream side end along this throughput direction.
Be transported to the printing medium (being typically record-paper) on the impression flat board, carry by this impression flat support and to throughput direction.Be configured in the record head of the dull and stereotyped top of impression, slide and the ejection ink droplet to main scanning direction, thus on this printing medium document image.At this moment, movably the support portion driver part can above-mentioned rotary middle spindle be that the center rotation drives.
The buckling parts of movable support portion fastens with gathering sill on the buckling surface that is formed on above-mentioned rotation board, therefore follow the rotation of movable support portion driver part, during the rotation of above-mentioned rotation board, the buckling parts of movable support portion moves swimmingly along this throughput direction between the above-mentioned throughput direction upstream-side-end of above-mentioned impression flat board and above-mentioned conveyance direction downstream side end.That is, movable support portion is followed this printing medium that transports and is slided to this throughput direction, and therefore, the end of this printing medium is always supported by movable support portion.Its result, the distance of above-mentioned printing medium and record head keeps constant, even also can realize the high image quality record when carrying out boundless record.
In addition, above-mentioned rotary middle spindle can be configured to extend to the direction vertical with above-mentioned main scanning direction and above-mentioned throughput direction both sides.At this moment, this rotary middle spindle is configured on the direction vertical with the face of the placement printing medium of above-mentioned impression flat board, therefore, constitute the rotation board of movable support portion driver part, can rotate under the state parallel being configured to the face that impresses the dull and stereotyped above-mentioned printing medium of support.Thus, the movable support portion driver part with this rotation board can be configured in the dull and stereotyped periphery of impression compactly.
Above-mentioned movable support portion can be driven by the motor that is used for the printing medium that is positioned on the above-mentioned impression flat board is carried to above-mentioned throughput direction.In this constituted, above-mentioned printing medium was carried to throughput direction by said motor.At this moment, by the effect of this motor, above-mentioned movable support portion driver part is that the center is driven in rotation with above-mentioned rotary middle spindle.Like this, movable support portion driver part will be used to carry the motor that is positioned at the printing medium on the impression flat board to be driven as drive source, so the smooth rotation of above-mentioned rotation board, thereby the slip smoothly that has realized above-mentioned movable support portion is moved.
Above-mentioned rotation board can be formed by above-mentioned rotary middle spindle and connect the discoid of its center.Form discoidly by rotating board, can make the simple in structure of movable support portion driver part, and realize being used to driving the densification design of the mechanism of this movable support portion driver part.
Above-mentioned gathering sill can form along the projected path curve, when being transported to the above-mentioned throughput direction upstream-side-end of above-mentioned impression flat board at above-mentioned printing medium, the buckling parts of above-mentioned movable support portion is slided to above-mentioned throughput direction upstream-side-end side, and follow the conveying of this printing medium, the buckling parts that makes above-mentioned movable support portion slides to above-mentioned conveyance direction downstream side with the state of the end of supporting this printing medium.In this constitutes, movable support portion, slide in the mode of temporarily meeting printing medium to the throughput direction upstream side, the conveying of this printing medium is followed in this movable support portion thereafter, with the state of the end of supporting this printing medium to this conveyance direction downstream side slip.Thus, the end of this printing medium always supported by movable support portion, so the distance of this printing medium and record head keeps constant effectively.
Above-mentioned projected path curve can be Archimedes spiral.In this constitutes, the rotation of the buckling parts accompanying rotation board of movable support portion, with the speed corresponding with this rotary speed from the center of rotation board to radially moving.Therefore, movable support portion can be followed with constant speed swimmingly corresponding to the transporting velocity of above-mentioned printing medium, can be synchronous with the printing medium that transports.Thus, when for example being rotated the driving of board by said motor and carrying out the high-resolution record, the amount of feeding of printing medium (line feed width) is set lessly, but corresponding with it, the anglec of rotation of rotation board also diminishes, and the amount of movement of movable support portion also diminishes.On the contrary, when hanging down exploring degree record, the amount of feeding of printing medium (line feed width) is set greatlyyer, but corresponding with it, and the anglec of rotation of rotation board also becomes greatly, and the amount of movement of movable support portion also becomes big.
It is the center left-right symmetry that above-mentioned Archimedian screw can form with imaginary reference axis, wherein, above-mentioned imaginary reference axis by above-mentioned rotation board the center and be formed on the above-mentioned buckling surface.In this constitutes, slide in the mode of temporarily meeting printing medium to the throughput direction upstream side from predetermined initial position in movable support portion, and directly continuously, follow the conveying of this printing medium, state with the end of supporting this printing medium slides to this conveyance direction downstream side, and then directly slides and get back to above-mentioned initial position to above-mentioned throughput direction upstream side continuously.Therefore, movable support portion always correctly is configured in predetermined initial position.
Ink-jet recording apparatus of the present invention also can have: limiting part, and the edge part of the throughput direction by being overlapped in record-paper, with this record-paper that transports and the distance limit between the record head within the specific limits; With keep out of the way mechanism, when carrying out boundless record, make limiting part keep out of the way not produce above-mentioned overlapping to the direction vertical with above-mentioned throughput direction.
Feeding recordable paper on the impression flat board, and record head is slided to the direction vertical with the throughput direction of record-paper (being main scanning direction) spray ink droplet simultaneously, thus on this record-paper recording scheduled image.Generally when document image, the distance between record-paper and record head keeps constant extremely important.This is because very fine from the ink droplet of record head ejection, so if above-mentioned distance becomes and makes image blurringly greatly then ink is diffused as vaporific, ink can permeate if above-mentioned distance diminishes then, its result can't carry out distinct image record.Variable in distance between record-paper and record head former because, distortion (initial deformation) such as the bending that record-paper has just produced on being transported to the impression flat board time and the wave inception phenomenon that in the image record, produces.
When the limit record is arranged, generally use common paper as record-paper.Especially when record-paper is the bigger thin paper of the common paper equidimension of A4 size, because the wave inception phenomenon that produces in the record, the edge part of the throughput direction of record-paper has easily from impressing having that flat board floats.On the other hand, boundless record is generally the recording mode that is used to print photographic image, and use taken a picture with ground paper such as glossy papers as record-paper more.This ground paper is difficult to bending, and is difficult to produce above-mentioned wave inception phenomenon, and therefore, the end of the throughput direction of record-paper has and is difficult to from impressing the tendency that flat board floats.
When the limit record was arranged, the above-mentioned edge part of limiting part and record-paper was overlapping.Therefore, even when the record-paper generation initial deformation that transports and in record during record-paper generation wave inception phenomenon, also can be within the specific limits with the distance limit between this record-paper and record head.In addition, when carrying out boundless record, above-mentioned limiting part is for example kept out of the way to the direction perpendicular to above-mentioned throughput direction, and therefore record-paper and the limiting part of carrying on the impression flat board can be not overlapping.Therefore, when carrying out boundless record, can not be blocked, and arrive the above-mentioned edge part of record-paper effectively from the ink droplet of record head ejection.In addition, as above above-mentioned, when carrying out boundless record, record-paper is difficult to float from impressing flat board, therefore do not have because of above-mentioned limiting part not with the overlapping situation that causes the decline of image quality of record-paper.
Above-mentioned limiting part is configured between the ink ejection face of above-mentioned impression flat board and record head, can have the elongated flat board that extends to above-mentioned throughput direction.And the moving area of the above-mentioned record head of ratio of this elongated flat board is near the part of above-mentioned throughput direction upstream side, and is crooked obliquely upward in the mode of the top that extends to above-mentioned ink ejection face.
Because above-mentioned limiting part is made of elongated flat board, therefore has the very simple advantage of structure of limiting part.And, because as above above-mentioned this elongated plate bending, when therefore the initial deformation of the record-paper on being transported to the impression flat board was big, when for example producing the distortion of the degree that contacts with record head, this record-paper was inserted between above-mentioned limiting part and the impression flat board effectively by this elongated dull and stereotyped guiding.Therefore, even also can avoid contacting of this record-paper and record head during the record-paper warpage, realize the distinct limit record that has.
Above-mentioned impression flat board can have the framework that is placed with above-mentioned record-paper at upper surface.The above-mentioned mechanism of keeping out of the way can have: input block, slide to the direction vertical with above-mentioned throughput direction under the effect of above-mentioned record head; Swivel plate rotatably is supported on the predetermined rotary middle spindle of being located on the said frame, rotates to predetermined direction according to the slip of above-mentioned input block; And slide unit, be connected with above-mentioned limiting part and fasten with the buckling parts of being located on the above-mentioned swivel plate, slide to the direction vertical according to the rotation of this swivel plate with above-mentioned throughput direction.
Above-mentioned record head moves back and forth on above-mentioned main scanning direction, follows the motion of this record head, and input block is to this main scanning direction displacement.Specifically, for example whenever the record head reciprocating motion, this record head pushes above-mentioned input block, and this input block slides thus.When this input block slided, swivel plate was to predetermined direction rotation.Follow the rotation of this swivel plate, slide unit slides to above-mentioned main scanning direction.Above-mentioned limiting part is connected with this slide unit, therefore slides by slide unit, and above-mentioned limiting part is to above-mentioned main scanning direction displacement.That is, above-mentioned limiting part slides to the direction perpendicular to above-mentioned throughput direction, and is above-mentioned overlapping not produce.
Above-mentioned limiting part can dispose on perpendicular to the direction of above-mentioned throughput direction in opposite directions.That is, preferably on main scanning direction, dispose a pair of limiting part in opposite directions.And the above-mentioned mechanism of keeping out of the way can have the rack-pinion mechanism that is located between a pair of slide unit, and described a pair of slide unit is connected with each limiting part.
Owing to dispose a pair of limiting part in opposite directions, therefore a pair of above-mentioned edge part and limiting part in opposite directions is overlapping.Thus, when the limit record is arranged, even above-mentioned wave inception phenomenon takes place, also can be within the specific limits with the distance limit between record-paper and record head.In addition, a pair of slide unit connects via rack-pinion mechanism, so each limiting part is equably to leaving perpendicular to the direction of above-mentioned throughput direction and keeping out of the way.Therefore, avoid record-paper and the limiting part carried on the flat board at impression overlapping effectively.
The above-mentioned mechanism of keeping out of the way also can have: rotation restricting unit, limit above-mentioned swivel plate to predetermined party rotation in the opposite direction, and remove this restriction by making above-mentioned input block slide into predetermined restriction cancellation position; And spring members, be installed on the above-mentioned swivel plate, accumulate deformation energy with this swivel plate accordingly to the anglec of rotation of above-mentioned predetermined direction.
Above-mentioned input block and rotation restricting unit, formation make swivel plate only limit its ratchet mechanism to opposite spin to above-mentioned predetermined direction rotation.Therefore, when record head moved back and forth, swivel plate rotated to predetermined direction, and the spring members distortion, accumulated deformation energy in this spring members.According to the slip of above-mentioned record head, when making above-mentioned input block slide into predetermined restriction cancellation position, remove the rotation restriction of above-mentioned swivel plate.That is, allow rotating freely of swivel plate.Therefore, the deformation energy of accumulating in the above-mentioned spring members is released, and above-mentioned swivel plate is to the opposite spin of predetermined direction.Swivel plate is to the opposite spin of predetermined direction, thereby above-mentioned limiting part is got back to initial position.That is, during feeding recordable paper, the above-mentioned edge part and the limiting part of this record-paper are overlapping on the impression flat board.
The above-mentioned mechanism of keeping out of the way also can have the slide-and-guide parts that the above-mentioned slide unit of guiding slides.By these slide-and-guide parts slide unit is slided swimmingly.Therefore, the action of limiting part is also smooth and easy.Keep out of the way mechanism, can have and be used to actuator that limiting part is kept out of the way to the direction vertical with the face of the paper that transports.

As shown in figure 12, when pushing butt parts 158 by balladeur train 38 on main scanning direction (being ON among Figure 15), Lock Part 139 is that rotate at the center with back shaft 159, becomes rotation and allows posture.That is, fasten pawl 161 and break away from from swivel plate 125, swivel plate 125 can just change (is that the center turns clockwise with Cylindorical rod 127).As mentioned above, make exit roller axle 92 when throughput direction rotates by LF motor 71, this rotation is delivered to swivel plate 125 via Poewr transmission mechanism 124, and this swivel plate 125 is just changeing.Its result, movable support portion 88 displacement shown in the line chart 170 of Figure 15, the order that the relative position relation of movable support portion 88, swivel plate 125 and rod unit 126 is pressed Figure 16 (b)～(d) changes.Below further the mobile of movable support portion 88 told about in detail.
Movable support portion 88, when initial between first fixing rib 102 and second fixing rib 103 (with reference to Fig. 9), but shown in Figure 15 center line Figure 170, with the front end of record-paper when the throughput direction upstream-side-end of the framework 100 of impression dull and stereotyped 42 is carried, movable support portion 88 is moved and is met this record-paper to the throughput direction upstream side.Specifically, by the just commentaries on classics of LF motor 71, to conveying roller 60 throughput directions rotations and to dull and stereotyped 42 transfer sheets of impression, and drive transmit this LF motor 71 just then swivel plate 125 is just being changeed.The direction of rotation of the swivel plate 125 of this moment is clockwise direction in Figure 14 and Figure 16.When swivel plate 125 was just changeing, the position 165 of the base end part 146 of rod unit 126 relatively moved along the direction of arrow among Figure 14 171.That is, the position 165 of above-mentioned base end part 146 and the distance of Cylindorical rod 127 diminish gradually along with the rotation of swivel plate 125.Therefore, shown in Figure 16 (b), rod unit 126 is that oscillation center is swung with pars intermedia 147, and its result makes movable support portion 88 move to above-mentioned throughput direction upstream side.After the anglec of rotation of swivel plate 125 reached 90 °, movable support portion 88 was configured in the position (primary importance) that enters between the first adjacent fixing rib 102, meets record-paper.In the present embodiment, as shown in figure 15, before the front end of record-paper arrives the throughput direction upstream-side-end of impression dull and stereotyped 42, movable support portion 88 move to this throughput direction upstream-side-end corresponding first location on.Therefore, the rib 121 of movable support portion 88 is covered from the top by record-paper.
Thereafter, as shown in the drawing, alternately repeat to cause the ink droplet ejection, reach the corresponding record-paper of exploring degree of carrying and setting according to predetermined line feed width by the slip of balladeur train 38, on this record-paper, carry out the image record.That is, shown in the line chart 168 of Figure 15, intermittently drive LF motor 71, according to predetermined line feed width transfer sheet off and on just to change mode.Make swivel plate 125 rotations linkedly with the driving of LF motor 71, therefore pass through as mentioned above transfer sheet off and on, swivel plate 125 also can intermittently rotate according to the predetermined anglec of rotation with it synchronously.The position 165 of the base end part 146 of rod unit 126, further the direction of arrow 171 moves in Figure 14, and the anglec of rotation of swivel plate 125 is returned to above-mentioned initial position when reaching 360 °.That is, the anglec of rotation of swivel plate 125 surpasses 90 ° and in the scope below 270 °, the position 165 of above-mentioned base end part 146 and the distance of Cylindorical rod 127, the rotation of accompanying rotation plate 125 and become big gradually.Therefore, shown in Figure 16 (b)～(d), rod unit 126 is that oscillation center is swung with pars intermedia 147, and its result makes movable support portion 88 move to above-mentioned conveyance direction downstream side.When the anglec of rotation of swivel plate 125 reached 270 °, movable support portion 88 was configured in the position (second place) that enters into the second adjacent fixing rib 103.And then by swivel plate 125 rotation, the position 165 of above-mentioned base end part 146 and the distance of Cylindorical rod 127, the rotation of accompanying rotation plate 125 and diminishing gradually.Therefore, rod unit 126 is that oscillation center is swung with pars intermedia 147, and movable support portion 88 is moved to above-mentioned throughput direction upstream side.When the anglec of rotation of swivel plate 125 reached 360 °, movable support portion 88 was returned to above-mentioned initial position.
When swivel plate 125 rotates like this, as shown in figure 12, fasten pawl 161 and on the upper surface 137 of rib 128, slide.Therefore, when the anglec of rotation of swivel plate 125 reaches 360 °, be embedded in the groove 131 (with reference to Figure 13) of swivel plate 125 the just commentaries on classics of restriction swivel plate 125 once more by the fastening pawl 161 of helical spring 157 application of forces.Swivel plate 125 just commentaries on classics is limited the time, Poewr transmission mechanism 124 stops, but owing to be provided with torque limiter 148, so the driving force of LF motor 71 is passed to conveying roller 60 and exit roller axle 92.Therefore, can guarantee the conveying smoothly of record-paper.
Under the state of the smooth and easy conveying of having guaranteed record-paper, record-paper is transferred off and on predetermined line feed width as shown in figure 15, proceeds the image record.At this moment, shown in this figure center line Figure 170, movable support portion 88 stops at above-mentioned initial position.And shown in line chart 173, the conveying of incident record paper, the rear end of this record-paper is near the throughput direction upstream-side-end of impression dull and stereotyped 42.The rear end of record-paper is detected by record sensor 95.According to this detection signal, control part 64 carries out the driving control of CR motor 73, thus, shown in the line chart 169 of Figure 15, balladeur train 38 is slided on main scanning direction and with above-mentioned butt parts 158 (with reference to Figure 12) butt (Figure 15 " ON ").
When pushing butt parts 158 by balladeur train 38 on main scanning direction, as mentioned above, Lock Part 139 is that rotate at the center with back shaft 159, fastens pawl 161 and breaks away from from swivel plate 125.Thus, swivel plate 125 can just change (is that the center turns clockwise with Cylindorical rod 127), its result, movable support portion 88 is subjected to displacement shown in the line chart 170 of Figure 15, and the relative position relation of movable support portion 88, swivel plate 125 and rod unit 126 changes according to the order of Figure 16 (b)～(d) once more.That is, before the rear end of record-paper arrived the throughput direction upstream-side-end of impression dull and stereotyped 42, the driving at intermittence by LF motor 71 moved to movable support portion 88 and this throughput direction upstream-side-end corresponding first location off and on.In addition, the rib 121 of at this moment movable support portion 88 is also covered from the top by the record-paper that transports.Thereafter, as shown in the drawing, alternatively repeat to cause the ink droplet ejection, reach the corresponding record-paper of exploring degree of carrying and setting according to predetermined line feed width by the slip of balladeur train 38, proceed image record to this record-paper.Make swivel plate 125 rotations linkedly with the driving of LF motor 71, therefore by driving LF motor 71 as mentioned above off and on, swivel plate 125 also rotates according to the predetermined anglec of rotation with it synchronously off and on.Rib 121 slides to conveyance direction downstream side with the state that is supporting record-paper under this state.
After swivel plate 125 rotates a circle, to be embedded in the groove 131 (with reference to Figure 13) of swivel plate 125 by the fastening pawl 161 of helical spring 157 application of forces once more, the just commentaries on classics of restriction swivel plate 125, and the relative position relation of movable support portion 88, swivel plate 125 and rod unit 126 is returned to initial position.And, after the image record end to this record-paper,, this record-paper is discharged to paper disc 21 (with reference to Fig. 3) just to change mode Continuous Drive LF motor 71.In addition, this moment, the rotation of swivel plate 125 was limited, but exit roller 62 rotates swimmingly by above-mentioned torque limiter 148 (with reference to Figure 12).
In addition, when the mode of image record being set at the limit record by operation aforesaid operations panel 4, above-mentioned balladeur train 38 not can with above-mentioned butt parts 158 butts.Therefore, not sliding as described above in above-mentioned movable support portion 88, stops at above-mentioned initial position and make.In addition, before limit when record being arranged, be preferably set at paper supply, make 71 counter-rotatings of LF motor.At this moment, as mentioned above, even Lock Part 140 does not fasten with swivel plate 125, by swivel plate 125 counter-rotatings, Lock Part 140 also must be embedded in the groove 134 of swivel plate 125, carries out initialization effectively.
In the compounding machine 1 of present embodiment, the record-paper that is transported on the impression dull and stereotyped 42 is supported by this impression dull and stereotyped 42, makes ink jet print head 39 slips on main scanning direction, sprays ink droplet simultaneously, thus on record-paper document image.This record-paper is also carried along throughput direction in document image, and this moment, as Fig. 9 and shown in Figure 15, slide along throughput direction with the state that is supporting record-paper in movable support portion 88.
As shown in figure 12, by this movable support portion 88 of rotation driving of swivel plate 125, and this swivel plate 125 is the center rotation with Cylindorical rod 127, and this Cylindorical rod 127 is perpendicular to the upper surface 109 of impression dull and stereotyped 42.That is, swivel plate 125 rotates being configured to and impressing under the parallel state of dull and stereotyped 42 upper surface 109.Swivel plate 125 effectively and compactly be configured in impression dull and stereotyped 42 near, its result can realize the miniaturization of image recording unit 24, and then can realize the densification design of compounding machine 1.
As shown in figure 16, rod unit 126 fastens with the gathering sill 143 of swivel plate 125, therefore the rotation of accompanying rotation plate 125, the leading section 145 of rod unit 126 moves along this throughput direction between the throughput direction upstream-side-end and conveyance direction downstream side end of impression dull and stereotyped 42.That is, movable support portion 88 is followed record-paper and is slided swimmingly, and the end of this record-paper is always supported by movable support portion 88, and record-paper can be with respect to the throughput direction bending.Therefore, as present embodiment, form groove 116 (with reference to Fig. 9) between first fixing rib 102 and second fixing rib 103, record-paper can be not sagging to these groove 116 sides yet, and the distance of record-paper and ink jet print head 39 keeps constant.Its result has realized the high image quality record to record-paper.
And movable support portion 88 is that drive source slides with LF motor 71, is therefore slided swimmingly in movable support portion 88.Therefore, has the advantage that can realize to the more high image quality record of record-paper.
In the present embodiment, movable support portion 88 and exit roller axle 92 interlocks that drive by LF motor 71.Generally in ink-jet recording apparatus, conveying roller be configured in record head near, 62 Poewr transmission mechanism 83, cleaning mechanism 51 etc. from conveying roller 60 to exit roller must keep predetermined geometrical locations relation with respect to these conveying rollers 60 and ink jet print head 39.Therefore, suppose that above-mentioned movable support portion 88 from obtaining driving forces with ink jet print head 39 near the conveying roller 60 that disposes, then is difficult to carry out the design of image recording unit 24 according to above-mentioned geometrical locations relation, it is complicated that mechanism also becomes.But in the compounding machine 1 of present embodiment, above-mentioned movable support portion 88 obtains driving force from spatially well-to-do exit roller 62 sides, so mechanism oversimplified, and also can further realize the Compact Design of compounding machine 1.
In addition, in the present embodiment, as the means that drive movable support portion 88, adopt to form discoid swivel plate 125, the drives structure of therefore movable support portion 88 is very simple, and also can make the mechanism design of swivel plate 125 rotations get compact with being used to.Therefore, can realize the further miniaturization of image recording unit 24.
And then owing to form the gathering sill 143 of above-mentioned shape on swivel plate 125, therefore as shown in figure 16, slide in movable support portion 88, and temporarily to meet record-paper to the throughput direction upstream side, the conveying of incident record paper is thereafter slided to conveyance direction downstream side.Thus, the end of record-paper is always supported by movable support portion 88, so the distance of this record-paper and ink jet print head 39 keeps constant comparatively definitely.Therefore, can realize record to the more high image quality of record-paper.
Particularly, in the present embodiment, the shape of above-mentioned gathering sill 143 is the Archimedian screw shape, so the leading section 145 of rod unit 126, corresponding to the rotation of swivel plate 125 from the center of this swivel plate 125 to radially moving (with reference to Figure 16).Specifically, there is linear relationship as mentioned above in the amount of movement of the anglec of rotation of swivel plate 125 and above-mentioned leading section 145, thereby with accordingly with the swivel plate 125 of constant speed rotation, promptly with according to the record-paper of predetermined line feed width intermittent delivery synchronously, movable support portion 88 is followed the conveying of record-paper swimmingly with constant speed.Therefore, when for example carrying out the high-resolution record, the amount of feeding of record-paper (width promptly enters a new line) is set lessly, but corresponding with it, swivel plate rotates off and on the small rotation angle.On the other hand, when hanging down exploring degree record, the line feed width of record-paper is set greatlyyer, but corresponding with it, and it is big that the anglec of rotation of swivel plate 125 becomes, and the amount of movement of movable support portion also becomes big.Have the following advantages thus: record-paper is supported by movable support portion 88 more effectively, keeps the distance of itself and ink jet print head 39 more exactly.
In addition, when the shape of for example above-mentioned gathering sill 143 is not Archimedian screw, above-mentioned swivel plate 125 sometimes with the line feed width of record-paper irrespectively, always be rotated with constant rotary speed.This can't directly produce some problem, but because swivel plate 125 rotates with constant speed, exist movable support portion 88 to surpass the possibility of the record-paper of carrying, at this moment, for example can be set at the ratio that carries out once with the every line feed pre-determined number of record-paper the slip of movable support portion 88 is stopped.
In the present embodiment, as Figure 14 and shown in Figure 16, gathering sill 143 according to above-mentioned Archimedian screw formation, with imaginary axis 144 is that benchmark is symmetrically formed, therefore slide from initial position (Figure 16 (a)) in movable support portion 88, temporarily meeting record-paper to the throughput direction upstream side, the conveying of direct incident record paper is continuously slided to conveyance direction downstream side with the state of the end of supporting this record-paper, and then directly return the throughput direction upstream side more continuously, get back to above-mentioned initial position.Therefore, movable support portion 88 always is configured in above-mentioned initial position exactly.This promptly means, even when carrying out recording occurring continuously on many record-papers, does not also need respectively each record-paper to be carried out above-mentioned initialization.Therefore have and carry out continuous recording advantage at a high speed.
In addition, in the present embodiment, can play following action effect.
In the present embodiment, be transported to the record-paper on the impression dull and stereotyped 42, at first support, and then be transported to second fixing rib, 103 sides by above-mentioned groove 116 by first fixing rib 102.This groove 116 especially when carrying out boundless record, can be caught the edge of the crossing record-paper ink droplet from ink jet print head 39 ejections.In the bottom of this groove 116, for example be equipped with the ink absorption materials such as sponge of sheet, can absorb the ink droplet that arrives in the groove 116 thus effectively.
As mentioned above, movable support portion 88 is covered by this record-paper by supporting record-paper, and therefore the ink droplet to the record-paper ejection can not be attached on the movable support portion 88.Therefore continuously on record-paper during document image,, can not produce the problem of reverse side that ink is made this record-paper dirty even in the time will opening record-paper and be configured on the movable support portion 88 with continuous next of this record-paper yet.
And then, owing to support record-paper, therefore can set the width dimensions 117 of above-mentioned groove 116 bigger by movable support portion 88.Thus, can realize the maximization of ink jet print head 39, and even ink jet print head 39 is maximized, above-mentioned groove 116 also can cover the integral body in the ink-jet zone 118 of this ink jet print head 39.Its result has the advantage of the high speed that can also realize boundless record.
In the present embodiment, the width dimensions 117 (with reference to Fig. 9) of above-mentioned groove 116 is set to bigger than the ink-jet zone 118 (with reference to Fig. 6) of ink jet print head 39.Thus, in the time of on record-paper being configured in impression dull and stereotyped 42, from all nozzle 53 ejection ink droplets of ink jet print head 39, this all ink droplet all can be caught by above-mentioned groove 116.Therefore, when carrying out boundless record, can and carry out the image record from all nozzles 53 ejection ink droplets of ink jet print head 39 to the end of record-paper.That is, carry out boundless record at a high speed, and do not need complicated control for ink droplet ejection from all nozzles 53.
In other words, the width dimensions 117 of supposing above-mentioned groove 116 is littler than the ink-jet zone 118 of ink jet print head 39, then when the fore-end of the throughput direction of record-paper carries out boundless record, must be only from the nozzle 53 ejection ink droplets of the upstream side of ink jet print head 39, and follow the conveying of this record-paper also to spray ink droplet from the nozzle 53 in downstream successively, need the complexity control of ink jet print head 39, relative with it, in the compounding machine 1 of present embodiment, do not need this complicated control, as mentioned above can be by carry out boundless record from all nozzle 53 ejection ink droplets to the record-paper end.That is, do not need to carry out complicated control, can carry out boundless record at high speed for ink droplet ejection from nozzle 53.
And then the section shape of said nozzle 53 may not be just round, and is attached with fine dust sometimes in nozzle 53, therefore, exist ink droplet can not be as the crow flies from nozzle 53 ejections and along the situation of a little incline direction ejection.In this case, because the width dimensions 117 of above-mentioned groove 116 is set greatlyyer than the ink-jet zone 118 of ink jet print head 39, so ink droplet can not be attached to the outside of groove 116.Its result has prevented that effectively the reverse side of record-paper from being made dirty by ink.
Particularly, the parts that support record-paper are first fixing rib 102, second fixing rib 103 and rib 121, and the structure of parts that therefore supports record-paper is very simple, and the contact area of each rib and record-paper is less.Therefore, the transporting resistance of record-paper is less, more swimmingly feeding recordable paper.In addition, chamfer machining (with reference to Fig. 9) is carried out in the bight 122,123 of the rib 121 of movable support portion 88, form inclined planes in this bight 122,123.Thus, even under the situation of the end of the record-paper that has passed through first fixing rib 102 and above-mentioned bight 122 butts, the end of this record-paper also can be directed on the movable support portion 88 swimmingly.Therefore, can not hinder the smooth and easy conveying of record-paper because being provided with movable support portion 88.In addition, as mentioned above, chamfer machining is carried out in each bight of first fixing rib 102 and second fixing rib 103, this part constitutes as the inclined plane.Therefore, even under the situation of the bight butt of the record-paper in conveying and first fixing rib 102 and second fixing rib 103, can not hinder the smooth and easy conveying of record-paper yet.
As shown in figure 16, with the rod unit 126 that the swivel plate 125 that rotates fastens, the rotation amount of swivel plate 125 is converted to the displacement of the throughput direction of above-mentioned movable support portion 88 with predetermined multiplying power.Thus, synchronously slide (with reference to Figure 15) with the conveying of record-paper in movable support portion 88, and the rotation amount of swivel plate 125 is exaggerated the displacement that is converted to throughput direction, so swivel plate 125 miniaturization that becomes.Its result can realize the more densification design of compounding machine 1.
In the present embodiment, as shown in figure 12, Lock Part 139 always fastens with swivel plate 125, and therefore except carrying out boundless record, movable support portion 88 can not followed record-paper and be slided.In this case, movable support portion 88 is configured between first fixing rib 102 and second fixing rib 103, therefore can be suppressed at the record-paper of carrying on the impression dull and stereotyped 42 and enter in the groove 116.And above-mentioned Lock Part 139 breaks away from from swivel plate 125 when carrying out boundless record, therefore, and the boundless record of change setting or in the record of limit any one arranged freely.

At this, this fastens bar 239 and is connected with the base 120 of movable support portion 88.This base 120 has along its length the slotted hole 241 that (being main scanning direction) extends, and above-mentioned fastening bar 239 is embedded in this slotted hole 241.This fastens the outside dimension of bar 239, and is corresponding with the internal diameter size of slotted hole 241, therefore, fastens bar 120, can not become flexible between itself and the slotted hole 241 for the direction beyond the scanning direction.
Therefore, as mentioned above, main body 237 swing, fasten bar 239 when being center circular-arc mobile with oscillation center axle 240, fasten bar 239 and slide on main scanning direction along above-mentioned slotted hole 241, above-mentioned base 120 slides along throughput direction simultaneously.In addition, as mentioned above, this base 120 supports its main scanning direction both ends slidably by said frame 100, so this base 120, the imaginary plane upper edge throughput direction (direction of arrow 101 among Figure 23) that is being parallel to above-mentioned upper surface 109 in the inboard of framework 100 slides swimmingly.That is, by the swing of above-mentioned tilting member 226, slide along throughput direction in above-mentioned movable support portion 88.
In the present embodiment, in Figure 23, go up to fasten above-mentioned fastening pin 238 in the precalculated position of gathering sill 143 (initial position).At this moment, movable support portion 88 is positioned at the central portion of framework 100, as shown in figure 18, and between first fixing rib 102 and second fixing rib 103.Movable support portion 88 is the same with above-mentioned first embodiment, is configured in this position usually.
In Figure 23, when ink jet print head 39 moved back and forth on main scanning direction, input block 224 was pushed off and on by scanning balladeur train 38.Thus, rotary part 125 according to the predetermined anglec of rotation (promptly according to the anglec of rotation corresponding) with the swivel feeding amount of above-mentioned tooth 235 off and on to right-hand rotation.During rotation, above-mentioned gathering sill 143 be center swing rotation with rotary middle spindle 234 like this for swivel plate 225, and therefore with the fastening pin 238 of above-mentioned gathering sill 143 fastenings, the rotation of accompanying rotation plate 225 is moved to left.And when the anglec of rotation of swivel plate 225 reached 90 ° (degree), the rotation that above-mentioned fastening is sold 238 accompanying rotation plates 225 began to move to right-hand, becomes till 270 ° to the right-hand anglec of rotation that moves until swivel plate 225.
Figure 24 and Figure 25 are the figure that schematically represents the relation that moves of the conveying of record-paper and movable support portion 88.
With above-mentioned first embodiment similarly, carrying out image when record, at first, for the record-paper that will be placed on the sheet feed stacker 20 is transported on the paper transportation path 23, control part 64 drives LF motors 71 with rotation paper feed roller 25.During paper supply, counter-rotating drives LF motor 71, by transmitting this driving, makes the direction rotation of paper feed roller 25 to feeding recordable paper, and conveying roller 60 and exit roller 62 are to the direction rotation opposite with throughput direction.Be transported to the record-paper of paper transportation path 23 from sheet feed stacker 20, carry in the mode of reversing upward from the below along paper transportation path 23, its front end and record sensor 95 butts, and then by carrying and conveying roller 60 and pinch roll butt.Conveying roller 60 is to the direction rotation opposite with throughput direction, so record-paper positions processing under the state of its front end and conveying roller 60 and pinch roll butt.This position location as among Figure 15 with reference to shown in the label 174.After the localization process of record-paper finished, control part 64 was just changeing driving LF motor 71.Thus, the record-paper after the localization process is shown in conveying on the impression dull and stereotyped 42 by conveying roller 60 and pinch roll clamping as this figure center line Figure 167.
When carrying out boundless record, movable support portion 88 is followed the conveying of record-paper and is slided.In detail, when record-paper is configured in above-mentioned position location 174, as mentioned above, movable support portion 88 is positioned at the central authorities of impression dull and stereotyped 42, as shown in figure 23, the base end part 146 of tilting member 226, be configured in the gathering sill 143 of swivel plate 225 the precalculated position (with among Figure 14 with reference to the identical position, position shown in the label 165: initial position).
With conveying roller 60 is after benchmark is located the front end of record-paper 246, intermittently to drive LF motor 71 shown in the line chart 168 of Figure 15, record-paper 246 is transported to the record position that impresses on dull and stereotyped 42.Thereafter, shown in line chart 169, CR motor 73 also drives in predetermined sequential.Thus, balladeur train 38 slides along main scanning direction, with input block 224 butts.The control of the slippage of the balladeur train 38 of this moment, be the driving control of CR motor 73, undertaken by above-mentioned control part 64.
When balladeur train 38 such slips and pushing input block 224, swivel plate 225 is right-hand rotation in Figure 23, and shown in Figure 24 (a), move to the throughput direction upstream side movable support portion 88.And when the anglec of rotation of swivel plate 225 reached 90 °, movable support portion 88 reached above-mentioned primary importance, meets record-paper 146.
Thereafter, in document image, balladeur train 38 slides, pushing input block 224.Thus, swivel plate 225 in Figure 23 further to right-hand rotation.Swivel plate 225 is further when right-hand rotation, and movable support portion 88 shown in Figure 24 (b), is followed this record-paper 146 with the state of the leading section that supporting record-paper 146 and moved to conveyance direction downstream side.And when the anglec of rotation of swivel plate 125 reached 180 °, shown in this figure (c), movable rib 104 arrived above-mentioned initial position (central portion of groove 116) from above-mentioned primary importance.
The anglec of rotation of above-mentioned swivel plate 125 becomes 180 °, when movable support portion 88 moves between first fixing rib 102 and second fixing rib 103, this movable support portion 88 remains on this position.And shown in Figure 25 (a), record-paper 246 is carried out the image record when throughput direction is carried.So, keep the means of movable support portion 88 simultaneously, control its sliding distance, make to keep the balladeur train 38 of ink jet print head 39 not get final product with input block 224 butts as feeding recordable paper 246.
Shown in Figure 25 (b), feeding recordable paper 246 and when making the rearward end of this record-paper 246 move on the movable support portion 88, slide to throughput direction once more in movable support portion 88, shown in this figure (c), follow this record-paper 246 with the state of the rearward end that supporting record-paper 246 and move to conveyance direction downstream side.Specifically, the slip by balladeur train 38 pushes above-mentioned input block 224 once more, makes swivel plate 225 right-hand rotation in Figure 23, thereby movable support portion is further moved to conveyance direction downstream side.And when the anglec of rotation of swivel plate 225 reached 270 °, movable support portion 88 arrived said second position.So, as making the mobile once more means in movable support portion 88 that stop at (initial position) between first fixing rib 102 and second fixing rib 103, control the sliding distance of this ink jet print head 39, make to keep the balladeur train 38 of ink jet print head 39 to get final product with input block 224 butts once more.
When discharging record-paper 246, keep the balladeur train 38 of ink jet print head 39 to make above-mentioned input block 224 slide into preposition (restriction cancellation position).At this moment, by controlling the driving of above-mentioned CR motor, make balladeur train 38 slide into preposition, thereby above-mentioned input block 224 slide into the restriction cancellation position.Specifically, as shown in figure 23, input block 224 slides to the direction of arrow 233, restriction cancellation arm 232 pushing butt pins 242.Thus, the elastic force of rotation restricting unit 227 antagonistic springs 244 and, remove the rotation restriction of swivel plate 225 to left rotation.As mentioned above, deformation energy is accumulated in being rotated in the above-mentioned spring members of accompanying rotation plate 225, and therefore by removing the rotation restriction of swivel plate 225, this deformation energy discharges, its result, swivel plate 225 reverse (left among Figure 23) rotation.The deformation energy of accumulating in the above-mentioned spring members comes from the rotation of swivel plate 225, and when therefore above-mentioned deformation energy all discharged, swivel plate 225 was to 270 ° of left rotations.That is, movable support portion 88 is returned to above-mentioned initial position once more.
In the compounding machine 1 of present embodiment, the record-paper of carrying on impression dull and stereotyped 42 246 is supported by this impression dull and stereotyped 42, and ink jet print head 39 slides on main scanning direction and sprays ink droplet simultaneously, thus on record-paper 246 document image.In document image, further carry this record-paper 246 along throughput direction, but this moment, as Figure 24 and shown in Figure 25, slide to throughput direction with the state that is supporting record-paper 246 in movable support portion 88.That is, the end of this record-paper 246 is always supported by movable support portion 88 when document image, therefore, and can be with respect to the throughput direction bending.Therefore, as described in present embodiment, even formed above-mentioned groove 116 (with reference to Figure 18 and Figure 19) between first fixing rib 102 and second fixing rib 103, record-paper 246 can be not sagging to these groove 116 sides yet, and the distance of this record-paper 246 and ink jet print head 39 keeps constant.Its result, compounding machine 1 the samely with above-mentioned first embodiment can carry out high image quality and print.
Detailed says, is transported to the record-paper 246 on the impression dull and stereotyped 42, is at first supported by first fixing rib 102, and then is transported to second fixing rib, 103 sides by above-mentioned groove 116.This groove 116 particularly when carrying out boundless record, can be caught the edge of crossing record-paper 246 ink droplet from ink jet print head 39 ejections.Thus, can prevent that ink is attached to the reverse side of record-paper 246.When record-paper 246 passed through on this groove 116, movable support portion 88 was followed the record-paper 246 that transports and is slided along throughput direction.That is, this record-paper 246 is supported from above-mentioned primary importance in movable support portion 88 when said second position is slided.Therefore, as mentioned above, the end of record-paper 246 is always supported effectively by movable support portion 88, prevents that record-paper 246 from entering in the above-mentioned groove 116.Its result, as mentioned above, the distance of record-paper 246 and ink jet print head 39 keeps constant, realizes the high image quality printing.
As shown in figure 22, this movable support portion 88 is driven by the rotation of swivel plate 225, and this swivel plate 225 is the center rotation with rotary middle spindle 235.That is, in the present embodiment, swivel plate 225 also rotates being configured to and impressing under the parallel state of dull and stereotyped 42 upper surface 109.Therefore, swivel plate 225 effectively and compactly be configured in impression dull and stereotyped 42 near, its result has realized the miniaturization of image recording unit 24, and then can realize the densification design of compounding machine 1.
In the present embodiment, by above-mentioned rotation restricting unit 227, the rotation of above-mentioned swivel plate 225 is restricted.At this moment, as Figure 22 and shown in Figure 23, input block 224 and rotation restricting unit 227, formation makes the only ratchet mechanism of right-hand rotation in Figure 23 of swivel plate 225.Therefore, when ink jet print head 39 moved back and forth, swivel plate 225 was to right-hand rotation, slided and support record-paper 246 along throughput direction effectively in movable support portion 88.At this moment, slip by above-mentioned control part 64 control ink jet print heads 39, can when ink jet print head 39 is reciprocal at every turn, push input blocks 224 and make swivel plate 225 rotations by balladeur train 38, in addition, also can be adjusted to, when the every back and forth pre-determined number of ink jet print head 39 by balladeur train 38 pushing input blocks 224 and make swivel plate 225 rotations.By the slip of such control ink jet print head 39, can make the line feed width of record-paper 246 synchronous with the slippage of movable support portion 88.
Owing on swivel plate 225, form the gathering sill 143 of above-mentioned shape, so during swivel plate 225 rotations, as Figure 24 and shown in Figure 25, slide in movable support portion 88, temporarily to meet record-paper 246 to the throughput direction upstream side, thereafter, the conveying of incident record paper 246 and sliding to conveyance direction downstream side.Thus, the end of record-paper 246 is always supported by movable support portion 88, so the distance of this record-paper 246 and ink jet print head 39 keeps constant more exactly.Therefore, can carry out the more record of high image quality to record-paper 246.
In the present embodiment, the shape of above-mentioned gathering sill 143 also is Archimedian screw, and therefore with corresponding with the swivel plate 225 of constant speed rotation, movable support portion 88 is followed the conveying of record-paper 246 swimmingly with constant speed.At this, if the intermittence of swivel plate 225, rotation was corresponding with the line feed width of record-paper 246, then the slip of movable support portion 88 is carried out synchronously with respect to the feeding of record-paper 246, and record-paper 246 is supported by movable support portion 88 more effectively.Therefore, the advantage that has the distance of keeping ink jet print head 39 and record-paper 246 more exactly.
In the present embodiment, between upper plate 177 and lower plate 178, dispose spring members, therefore the rotation of accompanying rotation plate 225, above-mentioned spring members distortion, accumulate the deformation energy corresponding with the anglec of rotation of swivel plate 225, but when discharging record-paper 246, by the slip of above-mentioned control part 64 control ink jet print heads 39, the input block 224 that is pushed by balladeur train 38 slides into above-mentioned restriction cancellation position.Thus, removed the rotation restriction of above-mentioned swivel plate 225, as mentioned above, the deformation energy that is accumulated in the above-mentioned spring members is released, and swivel plate 225 rotates to left, its result, and movable support portion 88 is returned to initial position (position shown in Figure 180).Like this, discharge this record-paper 246 after, initial position is got back in movable support portion 88, even when therefore carrying out recording occurring continuously on many record-papers 246, does not also need respectively each record-paper 246 to be carried out initialization, can carry out recording occurring continuously at a high speed.
In addition, in the present embodiment, as Figure 22 and shown in Figure 23, the gathering sill 143 that forms according to above-mentioned Archimedian screw is formed ring-type, therefore slides from above-mentioned initial position in movable support portion 88, temporarily meeting record-paper 246 to the throughput direction upstream side, the conveying of direct incident record paper 246 is continuously slided to conveyance direction downstream side with the state of the end of supporting this record-paper 246, and then directly return the throughput direction upstream side continuously, get back to above-mentioned initial position.Therefore, even omit above-mentioned spring members, movable support portion 88 also can always correctly be configured in above-mentioned initial position.Thus,, do not need respectively each record-paper 246 to be carried out above-mentioned initialization yet, can carry out recording occurring continuously at a high speed even when on many record-papers 246, carrying out recording occurring continuously.
In addition, in the present embodiment, support record-paper 246 by movable support portion 88, therefore the width dimensions 117 of above-mentioned groove 116 is set greatlyyer.Thus, can realize the maximization of ink jet print head 39, and even ink jet print head 39 maximizes, above-mentioned groove 116 also can cover the integral body in the ink-jet zone 118 of this ink jet print head 39.Its result has also realized the high speed of boundless record.Particularly, be rib owing to support the parts of record-paper 246, therefore have the very simple advantage of structure of the parts that support record-paper 246.And then the contact area of the record-paper 246 and first fixing rib 102, second fixing rib 103 and movable support portion 88 (rib 121) diminishes, therefore feeding recordable paper 246 swimmingly.
Same with above-mentioned first embodiment, in the present embodiment, the width dimensions 117 of above-mentioned groove 116 also is set greatlyyer than the ink-jet zone 118 of ink jet print head 39, even in the time of therefore on record-paper 246 not being configured in impression dull and stereotyped 42, from all nozzle 53 ejection ink droplets of ink jet print head 39, these ink droplets are also all caught by above-mentioned groove 116.Therefore, when carrying out boundless record, can and carry out the image record from all nozzles 53 ejection ink droplets of ink jet print head 39 to the end of record-paper 246.That is, can carry out boundless record at a high speed, and, not need complicated control about ejection from the ink droplet of nozzle 53.And then the section shape of said nozzle 53 may not be for just round, and be attached with fine dust sometimes in nozzle 53, therefore, sometimes ink droplet can't be as the crow flies from nozzle 53 ejections and along the direction ejection of a little inclination.In this case, because the width dimensions 117 of above-mentioned groove 116 is set greatlyyer than the ink-jet zone 118 of ink jet print head 39, so ink droplet can be attached to the outside of groove 116.Its result has prevented that effectively the reverse side of record-paper 246 from being made dirty by ink.
And then, chamfer machining (with reference to Figure 18) is carried out in the bight 122,123 of movable support portion 88, form the inclined plane in this bight 122,123.Thus, even when 122 butts of the bight of the end of the record-paper 246 that has passed through first fixing rib 102 and movable support portion 88, the end of this record-paper 246 also can be directed into the upper surface of movable support portion 88 swimmingly.Therefore, can not hinder the conveying smoothly of record-paper 246 because being provided with movable support portion 88.Similarly, also carry out chamfer machining in each bight 112～115 of first fixing rib 102 and second fixing rib 103, this part constitutes the inclined plane.Therefore, even the record-paper in conveying 246 during with above-mentioned bight 112～115 butts, can not hinder the conveying smoothly of record-paper 246 yet.
Particularly, in the present embodiment, as mentioned above, the balladeur train 38 that slides by CR motor 73 (with reference to Fig. 5) makes input block 224 slips (with reference to Figure 22 and Figure 23), slip by this input block 224 makes swivel plate 225 rotations, and the rotation of this swivel plate 225 is converted to the slip of movable support portion 88 by tilting member 226.That is, in the interlinked mechanism 105 of present embodiment, LF motor 71 is not the direct drive source of movable support portion 88, therefore can not hinder the correct conveying of record-paper 246.In addition, in the present embodiment, the drive source of movable support portion 88 is a CR motor 73, and because therefore zone (be zone image recording interval outside) the pushing input block 224 of CR motor 73 outside the sweep limits of balladeur train 38 can guarantee the correct conveying of the record-paper 246 in the image recording interval.
In addition, the above-mentioned of movable support portion 88 moved, and is special needs when record-paper 246 is carried out boundless record, but when the limit record is arranged, do not need moving of movable support portion 88.Movably therefore support portion 88 when the limit record is arranged, need not to drive movable support portion 88 usually in position standby shown in Figure 180, is fixed in position shown in Figure 180 and gets final product.At this moment, as the means of fixing movable support portion 88, the slip of adjusting ink jet print head 39 by control part 64 gets final product.That is, so that balladeur train 38 does not drive above-mentioned CR motor 73 with the mode of above-mentioned input block 224 butts gets final product.

In the present embodiment, the fastening pin 938 of above-mentioned tilting member 326 fastens with above-mentioned circular groove 336, and this circular groove 336 is the center rotation with the rotary middle spindle 334 at the center of support swivel plate 325.That is, be center swing rotation, with this rotary middle spindle 334 with respect to the circular groove 336 of rotary middle spindle 334 off-centre.And in Figure 33, fastening in the right positions of circular groove 336 has above-mentioned fastening pin 938.At this moment, movable rib 304 is positioned at the substantial middle portion of framework 300, as shown in figure 28, and between first fixing rib 302 and second fixing rib 303.Movable rib 304 is configured in this position usually.
In Figure 33, record head 39 is when main scanning direction moves back and forth, and input block 324 is pushed off and on by scanning balladeur train 38.Thus, rotary part 325 according to the predetermined anglec of rotation (promptly according to the anglec of rotation corresponding) with the swivel feeding amount of above-mentioned tooth 335 off and on to right-hand rotation.During rotation, above-mentioned circular groove 336 be center swing rotation with rotary middle spindle 334 like this for swivel plate 325, and therefore with the fastening pin 938 of above-mentioned circular groove 336 fastenings, the rotation of accompanying rotation plate 325 is moved to left.And when the anglec of rotation of swivel plate 325 reached 90 ° (degree), the rotation that above-mentioned fastening is sold 938 accompanying rotation plates 325 began to move to right-hand, becomes 270 ° to the right-hand angle that moves up to swivel plate 325.
Figure 34 and Figure 35 are the figure that schematically represents the relation that moves of the conveying of record-paper and movable rib.
Further detailed saying, movable rib 304, initially between first fixing rib 302 and second fixing rib 303 (initial position), but shown in Figure 34 (a), record-paper 346 when the throughput direction upstream-side-end of the framework 300 of impression dull and stereotyped 342 is carried, is moved to meet record-paper 346 to the throughput direction upstream side.Specifically, (with reference to Fig. 3 and Fig. 5) as mentioned above along transport path 23 feeding recordable papers 346, and is transported on the impression dull and stereotyped 342 by conveying roller 60 and pushing roller 361.Therefore,, during along transport path 23 feeding recordable papers 346, drive CR motor 73, scanning balladeur train 38 is slided as Figure 32 and shown in Figure 33.Thus, above-mentioned input block 324 is urged, and to right-hand rotation, movable rib 304 moves to the throughput direction upstream side swivel plate 325 in Figure 33.And when the anglec of rotation of swivel plate 325 reached 90 °, movable rib 304 arrived primary importance, meets record-paper 346.
, scanning balladeur train 38 slided, push above-mentioned input block 324 thereafter.Thus, further right-hand rotation in Figure 33 of swivel plate 325.At this moment, above-mentioned circular groove 336 is as mentioned above with respect to rotary middle spindle 334 off-centre, so swivel plate 325 is further when right-hand rotation, movable rib 304 is shown in Figure 34 (b), with the state of the leading section that supporting record-paper 346, follow this record-paper of transporting 346 and move to conveyance direction downstream side.And when the anglec of rotation of swivel plate 325 reached 180 °, shown in this figure (c), movable rib 304 arrived above-mentioned initial position (central portion of groove 316) from primary importance.
The anglec of rotation of above-mentioned swivel plate 325 becomes 180 °, movable rib 304 between first fixing rib 302 and second fixing rib 303 when mobile, and this movable rib 304 is maintained at this position.And shown in Figure 35 (a), record-paper 346 carries out the image record when throughput direction is carried.Keep the means of movable rib 304 simultaneously as such feeding recordable paper 346, control the sliding distance of this record head 39,39 the scanning balladeur train 38 of holding the record is not got final product with above-mentioned input block 324 butts.
Shown in Figure 35 (b), feeding recordable paper 346 and when making the rearward end of this record-paper 346 be positioned on the movable rib 304, movable rib 304 is slided to throughput direction, shown in this figure (c), with the state of the rearward end that supporting record-paper 346, follow this record-paper 346 that transports and further move to conveyance direction downstream side.Specifically, driving CR motor 73 (with reference to Fig. 5) slides scanning balladeur train 38.Thus, above-mentioned input block 324 is urged, and swivel plate 325 is right-hand rotation in Figure 33, and movable rib 304 further moves to conveyance direction downstream side.And when the anglec of rotation of swivel plate 325 reached 270 °, movable rib 304 arrived the second place.As the mobile once more means of the movable rib 304 that makes between above-mentioned first fixing rib 302 and second fixing rib 303 (initial position) like this, the sliding distance of control record head 309 makes to keep the scanning balladeur train 38 of this record head 39 to get final product with above-mentioned input block 324 butts once more.
When discharging record- paper 346,39 the scanning balladeur train 38 of holding the record makes above-mentioned input block 324 slide into precalculated position (restriction cancellation position).The slip of this scanning balladeur train 38 is undertaken by the driving control of above-mentioned CR motor (with reference to Fig. 5).Specifically, as shown in figure 33, input block 324 slides to the direction of arrow 933, restriction cancellation arm 332 pushing butt pins 942.Thus, the elastic force of rotation restricting unit 327 antagonistic springs 344 and, remove the rotation restriction of swivel plate 325 to left rotation.The rotation of accompanying rotation plate 325 is accumulated deformation energy in above-mentioned spring members, therefore by removing the rotation restriction of swivel plate 325, this deformation energy is released, its result, swivel plate 325 reverse (left among Figure 33) rotation.Because the deformation energy of accumulating in the above-mentioned spring members comes from the rotation of swivel plate 325, therefore, when above-mentioned deformation energy all discharged, swivel plate 325 was to 270 ° of left rotations.That is, movable rib 304 is got back to above-mentioned initial position once more.
In the compounding machine 310 of present embodiment, the record-paper of carrying on impression dull and stereotyped 342 346 is supported by this impression dull and stereotyped 342, sprays ink droplet, document image on record-paper 346 simultaneously by record head 39 is slided to main scanning direction.This record-paper 346 is further carried to throughput direction in document image, and this moment, as Figure 34 and shown in Figure 35, movable rib 304 with the state that supporting record-paper 346 to throughput direction slide (parallel moving).That is, the end of this record-paper 346 is always supported by movable rib 304 when document image, therefore can be with respect to the throughput direction bending.As described in present embodiment, even form above-mentioned groove 316 between first fixing rib 302 and second fixing rib 303, record-paper 346 can be not sagging to these groove 316 sides yet, and the distance of this record-paper 346 and record head 39 keeps constant.Its result has realized the high image quality printing.
Specifically, be transported to the record-paper 346 on the impression dull and stereotyped 342, at first support, and then be transported to second fixing rib, 303 sides by above-mentioned groove 316 by first fixing rib 302.This groove 316 particularly when carrying out boundless record, can be caught the edge of crossing record-paper 346 and from the ink droplet of record head 39 ejections.Thus, can prevent that ink is attached to the reverse side of record-paper 346.When record-paper 346 passed through on this groove 316, movable rib 304 was followed the record-paper 346 that transports and is slided to throughput direction.That is, movable rib 304 slides into the second place from above-mentioned primary importance, supports this record-paper 346 simultaneously.Therefore, the end of this record-paper 346 is always supported effectively by movable rib 304, and can not enter in the above-mentioned groove 316.
In addition owing to support record-papers 346 with movable rib 304, so the width of above-mentioned groove 316 can be set broad.Thus, record head 39 can maximize, even record head 39 maximizes, above-mentioned groove 316 also can cover the integral body in the ink-jet zone 118 of this record head 39.Its result has the advantage of the high speed of also having realized boundless record.
Particularly, be rib owing to support the parts of above-mentioned record-paper 346, therefore have the very simple advantage of structure of the parts that support record-paper 346.And then, because the contact area of record-paper 346 and first fixing rib 302, second fixing rib 303 and movable rib 304 is less, therefore feeding recordable paper 346 swimmingly.
In the present embodiment, the width of above-mentioned groove 316 is set to ink-jet zone 118 big (with reference to the Fig. 6) than record head 39.Thus, even when not having configuration record paper 346 on impression dull and stereotyped 342, from all nozzles (inkjet mouth 53) ejection ink droplet of record head 39, these ink droplets are also all caught by above-mentioned groove 316.In addition, movable member is positioned at the downside of paper, so movable member can not got wet.Therefore, when carrying out boundless record, can be from all nozzles ejection ink droplets of record head 39 and to the end document image of record-paper 346.That is, can carry out boundless record at a high speed, and also not need complicated control about ink droplet ejection from inkjet mouth 53.And then the section shape of above-mentioned inkjet mouth 53 may not be just round, and is attached with fine dust sometimes in inkjet mouth 53, and therefore, ink droplet is not to spray as the crow flies from inkjet mouth 53 but spray in the direction of a little inclination sometimes.Even in this case, because the width of above-mentioned groove 316 is set greatlyyer than the ink-jet zone 118 of record head 39, so ink droplet can be attached to the outside of groove 316.Its result can prevent effectively that the reverse side of record-paper 346 from being made dirty by ink.
In addition, in the present embodiment, chamfer machining (with reference to Figure 28) is carried out in the bight 322,323 of movable rib 304, form the inclined plane in this bight 322,323.Thus, even when 322 butts of the bight of the end of the record-paper 346 that has passed through first fixing rib 302 and movable rib 304, the end of this record-paper 346 also can be directed to the upper surface of movable rib 304 swimmingly.Therefore, can not hinder the conveying smoothly of record-paper 346 because being provided with movable rib 304.In addition, similarly, chamfer machining is also carried out in each bight 312～315 of first fixing rib 302 and second fixing rib 303, this part is constituted as the inclined plane.Therefore, even record-paper 346 and above-mentioned bight 312～315 butts in carrying can not hinder the conveying smoothly of record-paper 346 yet.
In the present embodiment, by being provided with above-mentioned driving mechanism 305, and as Figure 34 and shown in Figure 35, in the time of on record-paper 346 being transported to impression dull and stereotyped 342, movable rib 304 is temporarily met this record-paper 346 to the throughput direction upstream side, thereafter, follow the conveying of this record-paper 346, slide to conveyance direction downstream side with the state of the end of supporting record-paper 346.Thus, have the following advantages: the end of record-paper 346 is supported by movable rib 304 effectively, can prevent effectively that it from entering in conveying in the above-mentioned groove 316.
And, in above-mentioned driving mechanism 305, as mentioned above, the scanning balladeur train 38 that slides by CR motor 73 (with reference to Fig. 5) slides above-mentioned input block 324, and the slip of this input block 324 is converted to the slip of above-mentioned movable rib 304 via swivel plate 325 and tilting member 326.That is, LF motor 71 is not the direct drive source of movable rib 304, therefore has the advantage of the correct conveying that can not hinder record-paper 346.In addition, in the present embodiment, the drive source of movable rib 304 is a CR motor 73, but the zone (be zone image recording interval outside) of CR motor 73 outside the sweep limits of scanning balladeur train 38 pushes above-mentioned input block, therefore can guarantee the correct conveying of the record-paper 346 in the image recording interval.Certainly, if can guarantee the correct conveying of record-paper 346, also can be with the direct drive source of CR motor 73 or LF motor 71 as movable rib 304.
