Shown in Fig. 9 A and 9B, in axial direction the keyhole 65a of Yan Shening is formed in the axle head of axle 65.The projection 66a that forms in the interior week of pinion 66 is fitted to keyhole 65a, so that pinion 66 is provided with stationary state, can not slide with respect to axle 65.Here, axle 65 is the quill shafts by the bending machining formation of metallic plate.The fit structure that jut 65b that utilization forms in the end of metal pretreated sheet material material and sunk part 65c are fitted to each other can keep cylindrical for a long time.

To its end, this jut 65b has bigger width with jut 65b.This sunk part 65c has the form of the projection 65b that just is coupled to formation like this.Because above-mentioned sunk part 65c and jut 65b are fitted to each other to produce the wedging effect, the junction surface can not opened by the bounced-back-role of metallic plate, and need not the combination processing such as welding processing, and the form of cylinder axis can keep for a long time.

This keyhole 65a by the step portion 65d that forms in pretreated metallic sheet material and 65e are carried out bending machining so that end difference faces with each other forms.The junction essence of this cylinder axis is positioned at the middle body of keyhole 65a.Therefore, because keyhole 65a forms after the metallic plate bending, therefore, cutting processing is not carried out separately, and keyhole 65a can form easily and at an easy rate like this.In addition, the size of the width of keyhole 65a and length can be regulated easily.

As shown in FIGS. 6 to 8, in front view, have the first triangular shaped attachment 67 and be formed on the side surface of stacker 13, and be projected into guide member 54.In addition, be formed on the end of the bottom end side of stacker 13 to the second outstanding attachment 68 of device interior.On the other hand, first of first attachment, the 67 adjacency second adjusting parts 61 of regulating parts 57 and second attachment, 68 adjacency are formed on the side of guide member 54.First attachment 67 and first are regulated parts 57 and are formed first regulon 51; Regulate parts 61 with second attachment 68 and second and form second regulon 52.

Now, first regulon 51 and second regulon 52 as above-mentioned formation below will be described in more detail.Shown in Figure 11 A, first regulates parts 57 comprises: have first of substantial horizontal plane and regulate surface 58; Regulate surface 59 with second of the inclined surface that has downward extension and separate with first attachment 67.In addition, the second adjusting parts 61 comprise: form second and regulate the 3rd adjusting surface 62 of the lower surface part of parts 61; Regulate surface 63 with the 4th adjusting surface 63, the four and form the perpendicular surfaces, extend upward and form the inclined surface that separates with second attachment.In Figure 11 A to 13, in order to simplify the purpose of accompanying drawing, in fact be formed on first in the guide member 54 regulate parts 57 and second regulate parts 61 as independent parts by shown in the solid line.

When shown in solid line among Fig. 7 or Figure 11 A, when stacker 13 is arranged in the second place, utilize the own wt of stacker 13, axle 65 is pressed and contacts with the lower limb with bullport 55, and second attachment 68 enter the downside of the second adjusting parts 61 to regulate surface 62 in abutting connection with the 3rd.Or rather, because with respect to the position of the center of gravity of stacker 13, axle 65 is positioned at bottom end side, so the axle 65 that stacker 13 is easy in the figure turns clockwise.Yet second attachment 68 are in abutting connection with the 3rd adjusting surface 62, so that rotary manipulation is adjusted.Therefore, the second place of stacker 13 is held.In this second place, first attachment 67 do not engage with the first adjusting parts 57, and separate with it.In the second place, as shown in the figure, stacker 13 is arranged in wherein free end side direction obliquity slightly upwards.

Then, action bars 69 is pushed downwards from the state that stacker 13 is arranged in the second place.Or rather, when as the dummy line among Figure 11 A and label 13 ' shown in, axle 65 is in bullport 55 during by upwards displacement or displacement, second attachment 68 move to the 3rd end of regulating surface 62, and the free end of stacker 13 is pushed upwardly.Then, as shown in Figure 11 B, when action bars 69 was further pushed with upwards displacement or offset axis 65 downwards, second attachment 68 were regulated surface 62 from the 3rd and are moved to the 4th and regulate surface 63.After this, second attachment 68 are in abutting connection with the 4th adjusting surface 63, and upwards displacement or displacement of quilt.In a series of process, because first attachment 67 keep first junction surface to regulate the state that parts 57 separate with first, so the obliquity of stacker 13 is formed by second regulon 52 and axle 65.

Subsequently, when as among Figure 12 A shown in the variation from the dummy line to the solid line, when action bars 69 was further pushed with upwards displacement or offset axis 65 downwards, second attachment 68 and the 4th were regulated surface 63 and are separated, and first attachment 67 are regulated surface 59 in abutting connection with second.After this, first attachment 67 are in abutting connection with the second adjusting surface 59, and upwards displacement or displacement of quilt.Therefore, the rotary manipulation of stacker 13 is adjusted.Or rather, first regulon 51 is transferred to from second regulon 52 in the unit that forms the position of stacker 13.

Then, when shown in the variation from the dummy line to the solid line among Figure 12 B, when action bars 69 was further pushed with more upwards displacement or offset axis 65 downwards, first attachment 67 were from changing to the state of regulating surface 58 in abutting connection with first in abutting connection with second state of regulating surface 59.Therefore, the position of stacker 13 changes to the substantial horizontal position from obliquity, and finally changes to primary importance.In primary importance, utilize the own wt of stacker 13, first attachment 67 are pressed against first and regulate surface 58 from top.Since push compare stacker 13 with contact point center of gravity more near bottom end side, therefore in the drawings, stacker 13 is easy to turn clockwise.Yet because axle 65 is pressed against the top edge of bullport 55, so the rotary manipulation of stacker 13 is adjusted.Therefore, primary importance is maintained.

When first attachment 67 are regulated surface 59 in abutting connection with second, and during by upwards displacement or displacement (state shown in the dummy line among Figure 12 A), if the angle of inclination of stacker 13 is mild, first attachment 67 can not be pressed against second consumingly and regulate surface 59, can not be by upwards displacement or displacement.Therefore, when first attachment, 67 adjacency second were regulated surface 59 and made progress displacement or displacement, the angle of inclination expectation of stacker 13 was steep as much as possible.

When the stacker 13 that is changed to primary importance was by this way switched to the second place once more, action bars 69 was upwards pushed in the mode opposite with aforesaid way, with downward displacement or offset axis 65.Therefore, first attachment 67 are pressed against first state of regulating surface 58 and are changed to first attachment 67 are regulated surface 59 from side adjacency second state from top, so that first attachment 67 are in abutting connection with the second adjusting surface 59, and quilt displacement downwards or displacement.Then, first attachment 67 and second are regulated surface 59 and are separated, and second attachment 68 are regulated surface 63 from a side in abutting connection with the 4th.Then, second attachment 68 are in abutting connection with the 4th adjusting surface 63, and quilt displacement downwards or displacement.At last, second attachment 68 enter the downside of the second adjusting parts 61.These second attachment 68 are regulated surface 62 in abutting connection with the 3rd.Therefore, this stacker 13 is changed to the second place.

As implied above, first regulon 51 keeps the primary importance of stacker 13.In addition, when primary importance is switched to the second place, after primary importance is released, or when the second place is changed to primary importance, before the position is changed to primary importance, first regulon 51 with axle 65 with the position adjustments of stacker 13 to obliquity (wherein free end is by upwards directed obliquity).In addition, second regulon 52 keeps the second place of stacker 13.In addition, when the second place is switched to primary importance, after the second place is released, or when primary importance is changed to the second place, before the position is switched to the second place, second regulon 52 with axle 65 with the position adjustments of stacker 13 to obliquity (wherein free end is by upwards directed obliquity).

The position that forms as mentioned above changes unit 4 and comprises:

first regulon

51 and 52 two regulons of second regulon or rather, are used to regulate two unit of the position of stacker 13.Change in the process of operation in the position of stacker 13, the position changes the unit stacker 13 is remained to wherein free end side by upwards directed obliquity, and alternately conversion is used to regulate the function of the position of stacker 13.

Therefore, for being arranged on the axle 65 upper and lower motions in bullport 55 between first regulon 51 and second regulon 52, only carry out a shirtsleeve operation, change to the second place and the position change operation from the second place to the primary importance from primary importance to both direction so that can realize stacker 13.In addition, two regulons are used, so that the position can positively be kept respectively.Just, the position of stacker 13 changes operation and can only pass through operating operation bar 69 realizations up and down.Therefore, the position change operation of stacker 13 is more readily understood with simpler.

With reference to as described in Fig. 1, printer unit 10 according to the present invention has the scanner unit 9 on top as especially.Because scanner unit 9, this stacker 13 almost can not itself be operated by grasping stacker 13.Yet as mentioned above, action bars 69 is operated, so that dual mode can be changed in the position of stacker 13.This position changes operation can be than the easier execution of the structure that wherein grasps stacker 13 executable operations own.

In addition, second regulate surface the 59 and the 4th adjusting surface 63 formation in the manner as described below.In the process that is used for the position of stacker 13 is changed to from primary importance the second place, be changed when regulating surface 63 and regulate the state of position of stackers 13 in abutting connection with the 4th when regulating the states of regulating the position of stackers 13 in surface 59 in abutting connection with second by second attachment 68 by first attachment 67, satisfy at the angle of inclination of stacker 13: suppose that the angle of inclination before variation just (angle of inclination with respect to the horizontal plane of stacker 13 among Figure 13 shown in the dummy line) is that a1 and lucky angle of inclination (angle of inclination with respect to the horizontal plane of stacker 13 among Figure 13 shown in the solid line) after variation are a2, relation table is shown a1＞a2, and before variation, it is relative that second attachment 68 and the 4th are regulated surface 63 just.

Therefore, as shown in figure 13, regulate surface 59 when first attachment 67 and second and separate, and second attachment 68 regulate at surperficial 63 o'clock in abutting connection with the 4th, space C is formed on second attachment 68 and the 4th and regulates between the surface 63.In addition, second attachment 68 are regulated the upper end (T represents by Reference numeral) of the vertical surface on surface 63 through forming the 4th, and are positioned under the upper end.Therefore, in the process of displacement downwards or offset axis 65, second attachment 68 can not be hooked on the upper end T of the vertical surface that forms the 4th adjusting surface 63, and primary importance can positively be changed to the second place like this.

" the 3. structure of pallet "

Subsequently, with reference to Figure 14 and 15, the structure as the CD or the injected medium pallet 90 thereon of recording medium will be described below.

As shown in figure 15, pallet 90 has rectangular shape in vertical view, and form can be by transmitting driven roller 30 and transmit tabular that loose roll 31 clamps, and can carry out subscan according to the rotation that transmits driven roller 30 and present.

This pallet 90 forms by resin material is whole, to have tray main body 91 and placement section 92.As shown in the figure, this placement section 92 forms by have circular depressed part in vertical view.Protuberance 98 is formed on the central authorities of placement section 92.When CD was placed on the placement section 92, the medium pore of CD was mounted to protuberance 98, so that the position of CD in placement section 92 is determined.

The vertical direction of Figure 14 is the direction of transfer of pallet 90.When the stacker through being arranged in primary importance 13, this pallet 90 is inserted into (presenting) in the straight line drive access time, and top shown in Figure 14 is used as the end and inserts.More particularly, label 93 shows the end of pallet 90.With respect to horizontal surface 97 and inclined surface 96, extend to the direction of insertion (making progress among Figure 14) of pallet 90 this end 93.This will be discussed in more detail below.

Then, in the end 93 of pallet 90, tongue piece 94 and pallet 90 whole formation with outstanding to direction of insertion.In vertical view and side section view (not shown), this tongue piece 94 is to the end convergent, and its lower surface forms flat surfaces with the lower surface of tray main body 91.Be similar to tongue piece 94, in side section view (not shown), the end 93 of this pallet 90 is formed to the end convergent.

This end 93 is owing to following reason convergent.Just, when this pallet 90 is inserted in the straight line drive access, the stacker 13 through being arranged in primary importance, this pallet 90 is inserted to the inboard of equipment, and the end 93 of pallet 90 is placed on head position.At this moment, the roller position that utilization describes below changes unit 5, discharge loose roll 42 and discharge driven roller 41 and separate, and move forward to drive access, so that pallet 90 is sandwiched in discharge driven roller 41 and by (watching drive access from a side) between the pressure roller 78 by pressure roller 78 (Fig. 1).Then, in this state, discharge driven roller 41 and be rotated and drive, so that pallet 90 is fed to transfer roller 29.

For the subscan that utilizes transmission driven roller 30 and transmission loose roll 31 to carry out pallet 90 is presented, the end 93 of pallet 90 need be inserted into transmits between driven roller 30 and the transmission loose roll 31.Because the end 93 of pallet 90 disposes tongue piece 94, therefore when the rotation according to discharge driven roller 41, when pallet 90 was sent to transfer roller 29, tongue piece 94 entered transmission driven roller 30 and transmits between the loose roll 31.As a result, the end 93 of pallet 90 then enters and transmits between driven roller 30 and the transmission loose roll 31, so that pallet 90 is sandwiched between two rollers.

Or rather, because the area (according to vertical view) of the end of pallet 90 greatly reduced because of tongue piece 94, so the end 93 of pallet 90 can easily be inserted into less power and transmits driven roller 30 and transmit between the loose roll 31.Therefore, need not to be used for and will transmit loose roll 31 from transmitting the unit that driven roller 30 separates (release), pallet 90 also can be inserted into and transmit between driven roller 30 and the transmission loose roll 31.

In the end side of pallet 90, horizontal surface 97 and inclined surface 96 partly form near both side ends.Below will describe the function of horizontal surface 97 and inclined surface 96 in detail.

" 4. thrust unit and roller position change the structure of unit "

Subsequently, with reference to Figure 16 to 25, below detailed description is used for that paper is discharged frame assembly 45 pushes the structure of the thrust unit of contact position (torsion spring 49) to and be used for paper is discharged frame assembly 45 changes unit 5 from contact position displacement or the roller position that is displaced to the separation point position structure.

[structure of 4-1. thrust unit]

Shown in Figure 16 and 17, this paper is discharged frame assembly 45 and is comprised the paper discharge framework of being made by metallic sheet material 46; With the roller support component of making by resin material 47, and has the form of extending along main scanning direction (direction of paper width).

In roller support component 47, be used to support the retainer portion 44 that discharges loose roll 42 and formed so that exist along the main scanning direction compartment of terrain by whole.In addition, parts of bearings 47a and the 47a that is used to support following releasing parts 75 formed by integral body.

This paper is discharged frame assembly 45 and is configured to displacement or mobile between the primary importance (hereinafter being called " contact position ": referring to Fig. 2) and the second place (hereinafter being called " separation point position ": referring to Figure 26), wherein in primary importance: utilize not shown guidance unit, discharge loose roll 42 contacts and discharge driven roller 41; In the second place: discharge loose roll 42 and discharge driven roller 41 and separate.In addition, utilize Figure 19 A to the torsion spring shown in the 20B (thrust unit) 49, this paper is discharged frame assembly 45 and is pushed to move to contact position.

In the separation point position, this paper is discharged frame assembly 45 and is maintained in as shown in figure 26 the substantial horizontal position.This state comes from following reason.The top of the upstream side of this paper discharge frame assembly 45 is corresponding to the main scanning zone of balladeur train 35.Therefore, for example, when the position that paper is discharged frame assembly 45 was positioned at paper wherein and discharges the upwards directed obliquely obliquity of the upstream side of frame assembly 45, paper was discharged the end of the upstream side of frame assembly 45 and is interfered with balladeur train 35 undesirably.Therefore, as mentioned above, in the separation point position, paper is discharged frame assembly 45 and is placed in the horizontal level, can not separate with balladeur train 35 greatly so that paper is discharged frame assembly 45, and the interference of two assemblies is prevented to prevent that equipment from amplifying.

Now, below detailed description is used to promote the torsion spring (thrust unit) 49 of paper discharge frame assembly 45.As Figure 19 A to shown in the 20B, tongue piece 46a is formed on along in two ends (end is presented at Figure 19 A in 20B) portion of the longitudinal direction of paper discharge framework 46, and be parallel to paper drive access on the surface (upper face) of contact position side (in Figure 20 A and 20B, from the front portion of paper surface to the direction at rear portion) and extend.The distortion parts 49a of this torsion spring 49 is fitted to tongue piece 46a.

Then, an end 49b of this torsion spring 49 substantially perpendicularly is hanging to paper from distortion parts 49a and discharges framework 46, and engages with paper discharge framework 46.When paper discharge frame assembly 45 be arranged in shown in Figure 19 A and 20A contact position and when attachment 48a that the framework 48 that is arranged in equidirectional forms engages, with respect to distortion parts 49a, other end 49c is along discharging the direction extension that the direction of displacement (among Figure 20 A and the 20B up and down) of frame assembly 45 intersects with paper.Thereby when paper discharge frame assembly 45 was arranged in contact position, torsion spring 49 had the opening angle of regulation.

Because torsion spring 49 applies motive force to open an end 49b and other end 49c, therefore be used for along utilizing other end 49c to promote the component of force F of the vertical direction (paper is discharged the displacement or the direction of displacement of frame assembly 45) of the motive force F of junction surface 48a _VWith acting on paper is discharged the motive force that frame assembly 45 is pushed contact position to.

Here, discharge in the contact position of frame assembly 45 at the paper shown in Figure 20 A, because the other end 49c of torsion spring 49 extends with the displacement of right angle and paper discharge frame assembly 45 or the angle (precipitous angle) of the direction that direction of displacement (up and down) intersects with approaching, so component of force Fv is relatively large.Yet, as shown in Figure 20 B, when paper discharge frame assembly 45 is arranged in the separation point position, because the other end 49c of torsion spring 49 extends with the angle (angle of mitigation) near the direction of the displacement of discharging frame assembly 45 along paper or direction of displacement (vertical direction or up and down), so component of force Fv is less.

Or rather, be used to promote paper and discharge the torsion spring 49 of frame assembly 45 and be provided, so that the displacement operation change of frame assembly 45 is discharged in its position according to paper.In addition, along with paper is discharged frame assembly 45 and moved to the separation point position from contact position,, be used for that paper is discharged frame assembly 45 and push the component of force Fv of contact position to and reduce more according to the change in location of torsion spring.

This phenomenon is caused by following reason.Just, when carrying out printing on such as the paper P of common paper or fine paper, separate with discharge driven roller 41 if discharge loose roll 42, paper P can't be discharged from.Otherwise, the worry that exists paper P to float, record head 36 paper P that rub like this, and therefore, print surface is contaminated.Therefore, when the paper P such as common paper or fine paper was printed, paper was discharged frame assembly 45 and is also positively remained in the contact position with being supposed to.

Remain in the contact position in order positively paper to be discharged frame assembly 45, for example, strong compression spring or analogue are arranged on effectively that paper is discharged frame assembly 45 and between paper is discharged framework 48 on the frame assembly 45.Yet, when motive force increases by this way simply, if on the label surface of CD, carry out printing, along with frame assembly 45 moves to the separation point position from contact position, being used for that paper is discharged frame assembly 45 greatly increases from the operating physical force that the contact position displacement is displaced to the separation point position.As a result, merit size increases and has reduced operability.

Yet, as mentioned above, owing to discharge the displacement or the displacement operation of frame assembly 45 according to paper, be used for paper is discharged torsion spring 49 its positions of change that frame assembly 45 is pushed contact position to, and change in location according to torsion spring, along with frame assembly 45 moves to the separation point position from contact position, being used for that paper is discharged frame assembly 45 pushes the component of force Fv of contact position to and further reduces, therefore in needing the contact position of maximum impetus, be used to promote paper and discharge the motive force of frame assembly 45 and become maximum.Therefore, paper discharge frame assembly 45 can positively be kept.

Because along with paper is discharged frame assembly 45 when contact position moves to the separation point position, motive force further reduces, discharge frame assembly 45 when being indexed to the separation point position when paper, the merit size can not increase, and can prevent that operability from reducing.Especially in this embodiment, owing to insert when pallet 90 changes unit 5 by following roller position, paper is discharged frame assembly 45 by displacement or be displaced to the separation point position, therefore can reduce resistance that pallet 90 is inserted into and the insertion characteristic that can improve pallet 90.

In addition, torsion spring 49 is set at paper and discharges in the frame assembly 45, and the space that is used to install torsion spring 49 like this can be suppressed to minimum.Therefore, can make device miniaturization.

When paper discharge frame assembly 45 is arranged in the separation point position, discharge the displacement of frame assembly 45 or the component of force F of the direction that direction of displacement intersects with right angle and paper _HBecome big.Yet torsion spring 49 is arranged in the both ends of discharging the longitudinal direction of frame assembly 45 along paper, and therefore, even as component of force F _HDuring increase, they also can disappear each other mutually, have a negative impact thereby can not discharge frame assembly 45 to paper.

[4-2. roller position changes the structure of unit]

Next, detailed description is used for paper is discharged frame assembly 45 from the contact position displacement or be displaced to the separation point position and will change unit 5 from non-contacting position displacement or the roller position that is displaced to pressing position by pressure roller 78.

This change unit 5, roller position disposes the releasing parts 75 shown in Figure 21 to 26.This releasing parts 75 is formed with the spindle unit that extends along main scanning direction.The mode that its shaft end 75a and 75a cooperate with interlock is installed to parts of bearings 47a and the 47a that forms in as shown in Figure 16 the roller support component 47, so that releasing parts is supported to rotate freely by roller support component 47.

As shown in figure 21, rod unit 76 is formed near the shaft end 75a of releasing parts 75.In addition, near rod unit 76 and another shaft end 75a, press pressure roller 78 (for example, making) and supported respectively to rotate freely by parts of bearings 77 by rubber rollers.

Figure 22 has shown that discharge loose roll 42 contacts the state of (contact position that paper is discharged frame assembly 45) with discharge driven roller 41.Figure 26 has shown that discharge loose roll 42 separates the state of (separation point position that paper is discharged frame assembly 45) with discharge driven roller 41.Figure 23 to 25 has shown the state of paper discharge frame assembly 45 between contact position and separation point position; Figure 22 to 24 has shown the state that is positioned at non-pressing position by pressure roller 78.Figure 25 and 26 has shown the state that is positioned at pressing position by pressure roller 78.

As shown in the figure, discharge frame assembly 45 and be arranged in Figure 22 that contact position and stacker 13 are positioned at the state of the second place showing paper, rod unit 76 is projected into the drive access of pallet 90, and presses pressure roller 78 and regain (non-pressing position) from the drive access of pallet 90.Here, releasing parts 75 is pushed with rotation (among Figure 22 by the direction shown in the arrow mark γ), so that rod unit 76 is projected into the drive access of pallet 90 by the motive force of not shown pushing unit (for example, torsion spring).

Here, as shown in figure 17, this paper is discharged frame assembly 45 and is set in the top of stacker 13.Along in two ends of the longitudinal direction of roller support component 47, pin components 47b is formed downwards and dangles.

Shown in Figure 18 A and 18B, pin components 47b is positioned at and forms the top that the position changes the axle 65 of unit 4, and in the position of stacker 13 when the second place (Figure 18 A) changes to primary importance (Figure 18 B), engage with axle 65, so that pin components 47b by axle 65 upwards promote ormal weight (Figure 18 B, Figure 23).

Or rather, when the position of stacker 13 when the second place is switched to primary importance, paper is discharged frame assembly 45 and is pushed away ormal weight by axle 65 in advance.Thereby, when pallet 90 is manually inserted, paper discharge frame assembly 45 from contact position to the separation point position ormal weight that made progress displacement or displacement.Therefore, paper discharge frame assembly 45 by displacement backward or the amount of the merit when being displaced to the separation point position reduce, and can paper be discharged frame assembly 45 displacement easily or is displaced to the separation point position with the power of minimum.

Especially in this embodiment, discharge frame assembly 45 when being arranged in contact position, be used for paper being discharged frame assembly 45 and push the component of force of contact position (Figure 19 A and 19B) to and be suitable for becoming maximum by torsion spring 49 when paper.Or rather, begin the part in displacement from contact position, displacement or displacement for unit quantity, the merit size that paper is discharged frame assembly 45 becomes maximum, and as mentioned above, beginning position that part obtains stacker 13 from the displacement of the contact position that needs most merit quantity changes operation and guarantees.Therefore, discharge frame assembly 45 by displacement backward or when being displaced to the separation point position when paper, the merit size can further reduce, so that can paper be discharged frame assembly displacement easily or is displaced to the separation point position with very little power.

Now, shown in Figure 24 and 25, when pallet 90 by from the front portion of equipment when stacker 13 is inserted into equipment inboard, paper is discharged frame assembly 45 and is raised ormal weight under the state of separation point position, the attachment 95 of pallet 90 (referring to Figure 14 and 15) upwards rod member 76 and will be placed on the horizontal surface 97 of pallet 90 by pressure roller 78 with along the rotation of the clockwise direction among figure releasing parts 75.

Then, when pallet 90 when this state further is inserted into the inside of equipment, push contiguously by pressure roller 78 and horizontal surface 97, and releasing parts 75 is further rotated.Therefore, paper discharge frame assembly 45 is pushed upwardly.All pressing positions by pressure roller 78 are indicated in hereinafter described position by pressure roller 78 when pushing pallet 90 by pressure roller 78.

When pallet 90 further was inserted into equipment inboard, releasing parts 75 was arranged in releasing parts 75 wherein not by the settling position (position shown in Figure 26) of the reaction force rotation through receiving from pallet 90 by pressure roller 78.Then, press pressure roller 78 and on the inclined surface 96 that forms on the pallet 90, rise, further upwards promoted so that paper is discharged frame assembly 45.As shown in figure 26, this paper is discharged frame assembly 45 by displacement or be displaced to the separation point position.Label 78 among Figure 26 ' and the 78 " centre positions that pressure roller 78 is pressed in indication.

Here, owing to press pressure roller 78 and on inclined surface 96, rise, so that little by little increase the pressing force that is used to push pallet 90 by pressure roller, so load can not increase suddenly in the process that is used for inserting pallet 90, and pallet can be inserted with easily feeling invariably reposefully.

As mentioned above, since paper discharge frame assembly 45 through the rotary manipulation of releasing parts 75 by displacement or be displaced to the separation point position, and by pressure roller 78 by from non-pressing position displacement or be displaced to pressing position, therefore the release travel of paper discharge frame assembly 45 can increase, and the roller position changes unit 5 and can form at low cost, can as under the situation of using linkage, not increase the quantity of parts.

In addition, because pallet 90 is inserted into drive access, so that pallet 90 itself is discharged frame assembly 45 from the contact position displacement or be displaced to the separation point position with paper, and will be by pressure roller 78 from non-pressing position displacement or be displaced to pressing position, therefore discharge loose roll 42 and can not need special operatively positively separating with discharge driven roller 41, can or be displaced to pressing position from non-pressing position displacement by pressure roller 78, and can improve user's operability.In addition, roller 78 is pressed into and discharges driven roller 41 because pallet 90 is pressed, so the floating of pallet 90, and or rather, is placed on contacting to access positively and preventing of CD and discharge loose roll 52 on the pallet 90.In addition, owing to can rotate freely by pressure roller 78, so the transmission load of pallet 90 when being transmitted can be limited to minimum.

In this embodiment, paper is discharged frame assembly 45 by from the contact position displacement or the about 5mm of displacement when being displaced to the separation point position.This displacement comprises: the displacement that is changed about 3mm of operation by the position of stacker 13; Be formed on the pallet 90 when rising on the inclined surface 96 that forms the displacement of about 2mm with rotation releasing parts 75 and by pressure roller 78 with being inserted into when pallet 90.

In Figure 26, because pallet 90 is sandwiched in by pressure roller 78 and discharges between the driven roller 41, pallet 90 can be discharged driven roller 41 by rotation and be transmitted.Then, utilize the rotation of discharging driven roller 41, the pallet 90 upstream transfer roller 29 of side transmits.Utilization is formed on the effect of the tongue piece 94 (Figure 14 and 15) of its end, and the end of pallet 90 enters reposefully transmits between driven roller 30 and the transmission loose roll 31, so that pallet 90 is transmitted driven roller 30 and transmits loose roll 31 and clamp.After this, utilize the rotation that transmits driven roller 30, this pallet 90 is carried out subscan present,, and utilize record head 36 executive logging on CD to the downstream.

Owing to make releasing parts 75 trend along the rotation of the direction shown in the arrow mark γ among Figure 22, therefore when pallet 90 is discharged from, rod unit 76 is had an effect with to the end of discharging direction (among Figure 22 to 26 to the right) release pallet 90.Therefore, the discharge characteristic of pallet 90 is improved, so that pallet 90 can be discharged reposefully.

In addition, a plurality ofly be provided, and it is the symmetrical side of pallet 90 (in such an embodiment, near) along the position of main scanning direction with respect to the center of main scanning direction by pressure roller 78 (being two in this embodiment).Therefore, when pallet 90 was pressed

roller

78 and 41 transmission of discharge driven roller, pallet can correctly be transmitted, and can not produce crooked.

When paper discharge frame assembly 45 was arranged in contact position, by watching the paper drive access from this side, the rod unit 76 that forms in releasing parts 75 was projected into the paper drive access.Yet rod unit 76 is set at the outside of paper drive access along the scanning direction, can not stop paper P to be discharged from.In addition, be arranged on paper drive access inside along main scanning direction by pressure roller 78, yet, when paper discharge frame assembly 45 is arranged in contact position, as shown in figure 22, above the paper drive access, regain, so that can not prevent that by pressure roller paper P from discharging by pressure roller." 5. discharge driven roller, press the position relation between pressure roller and the pallet "

Next, discharge driven roller 41 with describing in detail, press the position relation between pressure roller 78 and the pallet 90.As mentioned above, pallet 90 is pressed roller 78 by to discharging driven roller 41.Yet, when pallet 90 when stacker 13 is inserted into record cell 32 (Fig. 2), if before the end 93 of pallet 90 arrives discharge driven roller 41, pallet 90 receives pressing force from pressing pressure roller 78, the end 93 of

pallet

90 and 41 collisions of discharge driven roller, " hooking sensation " when in other words, causing pallet 90 to be inserted into undesirably.

This is discharged driven roller 41 and is disposed in the high position with respect to the stayed surface 13a (more specifically, the top surface of rib 82) of pallet 90 and since when pallet 90 by when stacker 13 inserts, discharge driven roller 41 is caught positively to contact with the lower surface of pallet 90.

In addition, before the end 93 at pallet 90 arrived discharge driven roller 41, when pallet 90 received pressing forces from pressing pressure roller 78, pallet 90 promoted the ends of the bottom end side of stackers 13 downwards, so that stacker 13 is rotated counterclockwise on axle 65.Therefore, in primary importance, stacker 13 can not be kept for guiding the position (horizontal level in this embodiment) that is fit to of pallet 90.

Therefore, in this embodiment, before pushing pallet 90 by pressure roller 78, the end 93 of pallet 90 is designed to arrive discharge driven roller 41.

Especially Figure 24 has shown the state in the moment when tongue piece 94 arrives discharge driven roller 41.As shown in the figure, at this moment, also can not push pallet 90 by pressure roller 78.Then, Figure 25 has shown by pressure roller 78 and has been placed on moment (moment when being changed to pressing position by pressure roller 78) on the horizontal surface 97.At this moment, the end 93 of pallet 90 has arrived and has discharged driven roller 41.

Or rather, the end 93 of pallet 90 is with respect to extending along the direction of insertion of pallet 90 (among the figure left) as the horizontal surface 97 of the position that begins to push pallet 90 by pressure roller 78.Therefore, before pushing pallet 90 by pressure roller 78, the end 93 of pallet 90 arrives discharges driven roller 41.

When the end 93 of pallet 90 forms so that before pushing pallet 90 by pressure roller 78, arrive when discharging driven roller 41, does not extend the end 93 of pallet 90, but the position of discharging driven roller 41 (distributing roller 40) can be disposed in downstream (among the figure to the right).In addition, the roller position changes unit 5 (releasing parts 75) and can form, so that with the end 93 of pallet 90 arrive discharge driven rollers 41 simultaneously or the end 93 of pallet 90 arrive and discharge after the driven rollers 41, be placed on by pressure roller 78 on the upper face (horizontal surface 97 or inclined surface 96) of pallet 90.

As mentioned above, in the structure that comprises as the lower part: as the stacker 13 of the guidance unit that is used to guide pallet 90; Discharge driven roller 41, this discharge driven roller 41 is positioned between stacker 13 and the record cell 32 (Fig. 2), contacts and is rotated and drive with the lower surface of pallet 90; With press pressure roller 78, under pallet 90 is pressed the state that roller 78 pushes, should by pressure roller 78 with respect to discharge driven roller 41 be positioned at pallet 90 sides with pallet 90 from the upper face side of pallet by to discharging driven roller 41, the end 93 that can prevent pallet 90 is in abutting connection with discharging driven rollers 41.

As a result, can prevent the generation of " hooking sensation " when pallet 90 is inserted into, or its degree can reduce greatly.In addition, owing to be used to utilize the pressing force of pushing pallet 90 by pressure roller 78 directly not to be sent to stacker 13, therefore bring negative effect can not for 13 the position (horizontal level in this embodiment) of piling up that is positioned at primary importance, and the position that is used to support pallet 90 can be maintained at suitable state.

In the above-described embodiments, CD is placed thereon pallet 90 and is inserted into paper being discharged frame assembly 45 from the contact position displacement or be displaced to the separation point position, and will be by pressure roller 78 from non-pressing position displacement or be displaced to pressing position.Yet Cardboard Paper can be inserted into, and can be indexed to the separation point position from contact so that paper is discharged frame assembly 45.
