Detailed structure around the top cover:
Below, the structure around the top cover 22 is elaborated.
As shown in Figures 1 and 2, top cover 22 mainly comprises: the first 22A of wall section, the second 22B of wall section, the 3rd 22C of wall section discharge the part (driven roller 81 described later) of pallet 9, pallet cover 10 and distributing roller 8.
The first 22A of wall section is the wall that is configured in the top of distributing roller 8, and it forms the position that extends to the slightly front side of distributing roller 8 from the rear side on even keel of framework 21.The below of this first wall 22A of section (between the rearward end of top cover 22 and the longitudinal wall described later 91) is provided with fixing device 7.Specifically, fixing device 7 is configured in rear side (discharging the upstream side of direction) and the downside of distributing roller 8.In other words, the holding part between warm-up mill 71 and the backer roll 72 is configured in rear side and the downside of each holding part between driven roller 81 described later and each driven voller 82,83.
In this fixing device 7, warm-up mill 71 is configured in the front side with respect to backer roll 72, and the surface that contact with warm-up mill 71 of the paper P that discharges from fixing device 7 is discharged on this discharge pallet 9 to discharge pallet 9 ground.Thus, be discharged to the paper P that discharges on the pallet 9 and bend to protruding upward possibility change greatly.
The second 22B of wall section is the wall that is configured in the oblique front lower place of the first 22A of wall section, its form around discharge pallet 9 around " コ " word shape of (specifically, being front end and two ends, the left and right sides).The upper surface B1 of the second 22B of wall section is (downward-sloping to the downstream of discharging direction) inclination to oblique front lower place.
In addition, as shown in Figures 3 and 4, the upper surface 10A that is positioned at the pallet cover 10 that covers the position described later becomes same with respect to the upper surface B1 of the second 22B of wall section of such inclination.Thus, because can be suppressed at the situation that between the pallet cover 10 that covers the position and the second 22B of wall section around it, forms step, so, can improve the profile nature that pallet cover 10 is positioned at the laser printer 1 when covering the position.
As shown in Figures 1 and 2, the 3rd 22C of wall section is the wall that connects the first 22A of wall section and the second 22B of wall section, and it is to the direction extension that intersects with the first 22A of wall section and the second 22B of wall section.That is, near the second 22B of wall section the discharge pallet 9 of top cover 22 form than the first 22A of wall section low a step.Thus, can the degree of laser printer 1 miniaturization and miniaturization is more corresponding than the degree of the low step of the first 22A of wall section with the second 22B of wall section.
In addition, the rearward end of top cover 22 is supported on the framework 21 rotationally.In other words, top cover 22 is supported for and can rotates with respect to framework 21 centered by being arranged on the turning cylinder 22D that sees from the top in the scope that overlaps with the first 22A of wall section.
Thus, as shown in Figure 5, even if for example laser printer 1 is being accommodated in the situation about using in the narrow shelf R, owing to being positioned at the second 22B of wall section of turning cylinder D opposition side than the low step of the first 22A of wall section, therefore can open significantly top cover 22, so, can easily implement the replacing operation of handle box 6.
As shown in Figures 1 and 2, discharging pallet 9 and form from top cover 22(specifically, is the second 22B of wall section) upper surface to lower recess.Specifically, discharge pallet 9 have the longitudinal wall 91 that extends along the vertical direction, horizontal wall 92, the sheet material supporting walls 93 that is inclined relative to horizontal that along continuous straight runs extends and be disposed at about pair of sidewalls 94.
In addition, the bottom of longitudinal wall 91 becomes to oblique front lower place the rake 91B that (the top ends side direction to top cover 22 has a down dip) extends, and the deep of discharging pallet 9 is configured in the front side of longitudinal wall 91.Thus, as shown in Figure 5, when the user opens top cover 22 and sees near the outlet of fixing device 7 for example (structure of the turning cylinder 22D side of top cover 22), compare with the structure (structure that dots) of the lower end of in the past the longitudinal wall that will deep be set in upper downward-extension, the deep of discharging pallet 9 becomes and is difficult for obstructing the view.Therefore, in the structure of present embodiment, even top cover 22 is opened not too greatly, can see that also the outlet of fixing device 7 is neighbouring, also easily implement paperboard processing etc.
As shown in Figure 1, horizontal wall 92 is extended to the front side from the lower end of rake 91B and is connected with sheet material supporting walls 93, becomes the deep of discharge pallet 9.In other words, horizontal wall 92 is arranged between sheet material supporting walls 93 and the rake 91B.
Sheet material supporting walls 93 forms from the deep of horizontal wall 92() tilt to oblique front upper place.That is, the mutual distance of sheet material supporting walls 93 and rake 91B forms along with gradually separating towards the top from horizontal wall 92, thus, consists of respectively the part of wall of the groove of V-shape.
Thus, the rear end that is discharged to the paper P that discharges pallet 9 put rake 91B when upper, and the part of the rear end side of paper P is tilted the 91B of section and bends to protruding downwards with sheet material supporting walls 93.Thus, even if be discharged to the paper P that discharges on the pallet 9 upward in the situation of projection, between rake 91B and sheet material supporting walls 93, the part of the rear end side of paper P is corrected into the shape of projection downwards, thereby protruding upward curved shape can be corrected into more smooth shape.
Especially, in the present embodiment, by between sheet material supporting walls 93 and rake 91B, horizontal wall 92 being set, thus, with for example horizontal wall not being set the direct coupled structure of sheet material supporting walls and rake is compared, can between sheet material supporting walls 93 and rake 91B, do not formed narrow corner section.Therefore, owing to can suppress because paper enters into the situation that narrow corner section causes the curved shape overcorrection of paper, therefore can correct well the curved shape of paper P.
Such as Fig. 1～shown in Figure 3, pallet cover 10 is supported on the framework 21, and can rotate centered by near the turning cylinder (omit among the figure and illustrate) the front end that is disposed at sheet material supporting walls 93.Specifically, pallet cover 10 can and and be discharged between the adjacent extended position in the front side of upper surface (upper surface of sheet material supporting walls 93) of pallet 9 and rotate (removable) in the covering position of the upper surface (part of the upper surface of sheet material supporting walls 93 and horizontal wall 92) of cover discharging pallet 9.
In addition, the other parts of horizontal wall 92 and rake 91B are covered by the 3rd 22C of wall section of top cover 22 and the first 22A of wall section.Therefore when pallet cover 10 being configured in the covering position, can suppressing dust by pallet cover 10, the 3rd 22C of wall section and the first 22A of wall section and accumulate in the discharge pallet 9.
In addition, be in the end of upstream side of discharge direction of the rearward end 10B(paper P of the pallet cover 10 that covers the position) be positioned at the below of the holding part (holding part between driven roller 81 described later and the first driven voller 82) of distributing roller 8.Thus, even if cover the position in the situation that pallet cover 10 is positioned at, the paper P that discharges from the holding part of distributing roller 8 also can pass through on pallet cover 10, therefore, can suppress the lower surface butt of paper P and pallet cover 10 and situation about clogging.
In addition, covering the position, the upper surface of pallet cover 10 is (downward-sloping to the downstream of discharging direction) inclination to oblique front lower place.Thus, pile up dust even be positioned on the pallet cover 10 that covers the position, also can suppress the situation that this dust is fallen the corner of the rear side (distributing roller 8 sides) of discharging pallet 9.
In addition, as shown in Figure 2, pallet cover 10 has first and prolongs and cover the 11 and second prolongation and cover 12.First prolongs and cover 11 to form its width (length on the left and right directions) roughly the same with the width of discharge pallet 9, and shown in the long and short dash line of Fig. 1, form the position of the rear side of the front end that extends to the 3rd 22C of wall section in the covering position from the position of the front side of the front end of sheet material supporting walls 93.
Specifically, the lower end of the 3rd 22C of wall section is formed with upward the breach C1(that hollowly forms with reference to Fig. 2), covering the position, first prolongs and covers the rear side that 11 rear end is positioned at the edge of this breach C1.
As shown in Figure 2, second prolongs and cover 12 and first and prolong and cover 11 and compare width and form narrowlyer, and it is arranged on the substantial middle section that 11 leading section is covered in the first prolongation that is positioned at extended position rotationally.Specifically, second prolong cover 12 can be folded in the face of first prolong cover 11 reception position and and the first prolongation of being positioned at extended position cover rotation between the adjacent release position (position of Fig. 2), the front side of 11 upper surface.

Thus, can improve the transporting of paper P by the first larger driven voller 82 of diameter, and can be by the miniaturization of less the second driven voller 83 implement devices of diameter.Especially, in the present embodiment, be disposed at the diameter of first driven voller 82 of discharging the direction downstream by increase, thereby can make the angle (for the angle that enters of first driven voller 82 in downstream) that enters of the paper P that transports from the holding part between the second driven voller 83 and the driven roller 81 relax situation about blocking therefore can suppress first driven voller 82 in paper P and downstream to touch.
Namely, shown in Fig. 7 (b), when the first driven voller 82 ' of conveyance direction downstream side than the second driven voller of upstream side 83 ' hour, the tangent line T2 angulation θ 2 at the some P2 place of meeting this common tangent TC on the common tangent TC of driven roller 81 and the second driven voller 83 ' and the first driven voller 82 ' diminishes.Therefore, in this case, the possibility of blocking from first driven voller 82 ' of paper P in the downstream that transports between driven roller 81 and the second driven voller 83 ' is higher.
On the contrary, in the structure of present embodiment, shown in Fig. 7 (a), the tangent line T1 angulation θ 1 at the some P1 place of meeting this common tangent TC on the common tangent TC of driven roller 81 and the second driven voller 83 and the first driven voller 82 becomes large.Therefore, in the present embodiment, can suppress the situation of touching, blocking from first driven voller 82 in the paper P that transports between driven roller 81 and the second driven voller 83 and downstream.
Such as Fig. 5 and shown in Figure 6, driven roller 81 rotatably is arranged at top cover 22, the first driven vollers 82 and the second driven voller 83 rotatably is arranged at framework 21.Thus, as long as open top cover 22, can take out simply the paper P that between driven roller 81 and each driven voller 82,83, sticks.
In addition, the first driven voller 82 and the second driven voller 83 be side by side configuration on the direction that is inclined relative to horizontal, and becomes direction towards oblique below from the second driven voller 83 towards the direction of the first driven voller 82.Thus, with two driven vollers for example in the horizontal direction side by side the structure of configuration compare, can reduce the first driven voller 82 with respect to driven roller 81 to the overhang of discharging the direction downstream.
In addition, by reducing like this first driven voller 82 with respect to the overhang to discharge direction downstream of driven roller 81, thus, compare with the structure that two driven vollers horizontally (are given prominence to quantitative change large), even the position of longitudinal wall 91 deflection is discharged the direction upstream side, longitudinal wall 91 in the time of also can preventing top cover 22 switching and the interference between the first driven voller 82 are discharged pallet 9 therefore can enlarge.
The below of the first 22A of wall section of top cover 22 is provided with from fixing device 7 to distributing roller the lead transport path 100 of usefulness of 8 couples of paper P.Transport path 100 forms raise up circular-arc.
In addition, the holding part of distributing roller 8 (holding part between driven roller 81 and each driven voller 82,83) is configured in the position of oblique front lower place on the summit 110 of transport path 100.Thus, with for example towards the position of the oblique upper that is disposed at fixing device roughly lead the as the crow flies transport path of recording sheet of the distributing roller of (near the position the summit 110 of Fig. 6) compare, the position of distributing roller 8 can form circular-arc degree with transport path 100 and descend accordingly, therefore can realize the miniaturization of laser printer 1.
In addition, because compare with near the structure distributing roller 8 is arranged on summit 110, can make the position of distributing roller 8 be positioned at the front side, so also the position of lower end (namely discharge pallet 9 deep) of rake 91B of longitudinal wall 91 that is arranged on the below of this distributing roller 8 can be moved on to the front side, therefore can make near being configured in to become when top cover 22 is opened and more easily the seeing outlet of fixing device 7.
