So, because the operating portion 61 that can make the cover lock of loam cake 18 rocker switch decide means 60 is configured in 41 li of page paper constructional surfaces that storehouse has page paper S, because when on page or leaf paper constructional surface 41 state of page paper being arranged, operating portion 61 is covered by page or leaf paper, just can prevent to rotate open loam cake 18 effectively.
In the image processing system of configuration scanner 100, not comparing with there being scanner 100 above page or leaf paper mounting portion 40, is inevitable to the visual cognition of the page or leaf paper of storehouse or the deterioration that page or leaf paper takes out property.Here, in the image processing system of present embodiment, take out property in order to improve the page or leaf paper visual cognition or the page or leaf paper that have worsened, as shown in Figure 1, 2, since before space operation page or leaf paper mounting portion 40, between scanner 100 and the device body 1 face peristome 42 very big to open front, just can suppress the deterioration of the taking-up of page paper S that discharges by page or leaf paper mounting surface 41.In addition, by two fixed support portions 51,52, scanner 100 can be along discharging the arrow B direction slip that direction Xa parallels with the page or leaf paper of Fig. 2 with fixing support, scanner 100 is after side is slided inwards, and the space of the interval formed front openings portion 42 between page or leaf paper row paper portion 25 and the scanner 100 is expanded.
Further, for page or leaf paper visual cognition and the page or leaf paper taking-up property of optimizing front openings portion 42, in the angle below the front of scanner 100, be formed with the 1st gradient 137, similarly, in above the control panel 16 of device body 1, be formed with the 2nd gradient 19, thus the open aperture area of front openings portion 42.Particularly, the 2nd gradient 19 in the present embodiment is the outsides towards peristome, makes the aperture area open terrain become the gradient shape, just makes that operation became easy when hand inserted the page or leaf paper that peristome is discharged from taking-up.It is such that this formation both can be arranged to the 1st gradient portion 137, also can be not adopt the gradient shape, so long as can be open the aperture area of front openings portion 42, whatsoever shape can.
Taking-up to the page or leaf paper S that is discharged from explains below.
In Fig. 6 and Fig. 7, in the upper right of page or leaf paper mounting portion 40, go page operation of paper mounting surface 41 for convenience, be formed with the excision portion 43 lower than page or leaf paper mounting surface 41, the right side forms the face that tilts upward towards the upstream that page or leaf paper is discharged direction Xa.Thus,, be not only front openings portion 42, even taking-up from the side also can be guaranteed good taking-up for the bigger user of hand.In addition, in the present embodiment, though be that excision portion 43 is formed on upper right, need not superfluous words is arranged on upper left-hand with excision portion 43 and also can obtains same effect.
In addition, the left and right sides support component 51,52 of fixed support scanner 100, as shown in Figure 7, be not to be symmetrical, look from the front, the support portion 51 on right side is corresponding to above-mentioned excision portion 43, and is shorter than the length of left side support portion 52 on the dark direction in footpath in the length on the dark direction in footpath.That is, be L1 shown in Figure 8 with the length on the dark direction in footpath of the support portion 51 on right side, when being L2 shown in Figure 1 with the length on the dark direction in footpath of the support portion 52 in left side, it constitutes L1＜L2.Thus, the taking-up of the row's page paper S that is carried out from excision portion 43 has also become well, further, because the daylighting of excision portion 43 is also easier, makes the visual cognition of discharging page or leaf paper also become good.About the intensity of at this moment support portion 51,52, owing to will dispose the support portion 52 in the left side of the heavy side of automatic manuscript handling device 120, elongated with respect to the support width of the dark direction in footpath, so do not have problems yet.
Decide at the cover lock of page or leaf paper mounting surface 41 near the operating portion 61 of means 60, a part is provided with the recess 44 of being convenient to hold operating portion 61 as described above, by enlarging the width of this recess 44, can be used to choose the finger insertion space of getting page paper by double as.Under the occasion of Fig. 1 and Fig. 6, owing to discharge a page paper with guide center, so be to form recess 44 for the separatrix left and right symmetrically with the central reference, and, because the two ends of recess 44 are positioned at the big position of Rack of the page or leaf paper that uses than this device, can become can catch as the postcard size with paper, point the space of stretching into.
Further, the explanation that above-mentioned cover lock is decided means 60 replenishes.The operating portion 61 that cover lock is decided means 60 is set to accept the page or leaf paper of page paper mounting surface 41 and the dip plane that tilts, and the top setting of operating portion 61 is not protrude in a page paper mounting surface 41.Constitute by this, can prevent that the rear end of the page or leaf paper of discharging from not running into the operating portion 61 that cover lock is decided means 60 along the dip plane landing time, and cause page paper by messy ground storehouse.In order to obtain such effect, except that above-mentioned formation, page or leaf paper rear end is come compared with the position in the row's of dropping on paper disc, more can be positioned at the downstream side that page paper is discharged direction, perhaps when page or leaf paper falls with deadweight, the operating portion 61 that cover lock is decided means 60 is set near escape hole.
The operating portion 61 that cover lock is decided means 60 is arranged in the dip plane of page or leaf paper mounting surface 41 of row's paper disc of expressing as Fig. 1 and Fig. 6 because of it, all right from installing positive visual cognition, when the front openings portion 42 from device the place ahead takes out page paper, just can decide the operating portion 61 of means 60 by the visual cognition cover lock.Further, operating portion 61 can also be positioned at than in the scanner 100 front ends position more on the front.Thus, better from installing positive visual cognition, when the front openings portion 42 from device the place ahead takes out page or leaf paper, more can decide the operating portion 61 of means 60 by the visual cognition cover lock.
The configuration of image recording portion 2 and scanner 100 (automatic manuscript handling device 120) is to make the page or leaf paper discharge direction Xa of image recording portion 2 (positive towards the dark side in footpath from installing) and the sub scanning direction (original copy direction of transfer) of scanner 100 (automatic manuscript handling device 120) be orthogonal.The front of device body 1 disposes as shown in Figure 2 than scanner 100 and support portion 51,52 control panel 16 of front upper outstanding, that be positioned at this device body 1 more forward.Thus, just can fully guarantee front openings portion 42, the discharge of the flash page paper that comes from the top or the visual cognition and the operability of the operating portion 61 that cover lock is decided means 60 also improve.
Then, constitute, take out property or guarantee to support the intensity of scanner 100 or the viewpoint of resiliency is described in more detail from page or leaf paper about the inside of support portion 51,52 and scanner 100.In Fig. 8～Figure 11, the configuration that is provided with the scanner 100 of automatic manuscript handling device 120 is, from the front, the optics moving assembly 130 of scanner inside is positioned at the position relative with the support portion 52 in left side, send back the transfer part from installing the front original copy, it is original copy mounting dish that automatic manuscript handling device 120 also is configured to the left side, and original copy discharge dish is for open to the right.
From the device front, the support portion 51 on right side is littler than the support portion 52 in left side.Its reason is, owing to the scanning element that constitutes scanner 100 and possess and print the optics moving assembly 130 that car forms and be configured in the left side, is being partial to greatly because of the loading of scanner 100 outside the left side, also consider the user from the right side to operation with paper.That is from bearing the little device front of scanner 100 weight, the support portion 51 on right side is with little formation and be provided with the root of support portion 51 lower.
That above-mentioned formation is considered is right-handed person's user, and it is most providing convenience property of user.Further,, in the drive system of scanner 100,, and pass on system, also be configured in the left side from installing the front by the driving that gear set etc. constitutes as the CD-ROM drive motor 131 of driving means as Figure 10 and shown in Figure 11.In scanner 100 the insides, a part has scanning element (not shown) that reads the original copy that is placed and the CD-ROM drive motor 131 that drives this scanning element as mentioned above.CD-ROM drive motor 131 is transmitted by band on opportunity (timing belt) and is driven and the driven sweep unit.
In Figure 10 and Figure 11, symbol 105 expression is as the lower box of scanner 100 frameworks, symbol 106 expressions shown in the dotted line be the low profile line that has disposed lower box 105 outside the following teat of CD-ROM drive motor 131, scanner 100.
So, the part of the left front end shown in two figure in the scanner 100 protrudes in the top below of opening 59 described later.Then, on opening 59 below in the left front end of outstanding scanner 100, configuration is as the CD-ROM drive motor 131 of driving means.
As mentioned above, be provided with the scanner 100 of automatic manuscript handling device 120, impartial about being not from installing the front, as support portion 51,52, the support portion 52 in left side is designed to bear bigger loading than the support portion 51 on right side, and keeps balance.Therefore, the support portion 52 in left side not only is being set at L2＞L1 as shown in Figure 8 on the dark direction in footpath, and the width W 2 that its width also is set at the support portion 52 in left side is greater than the width W 1 (W2＞W1) of the support portion 51 on right side.
Thus, the user obtains very big improvement to the taking-up of the page or leaf paper of discharge.The taking-up of page paper is considered in the support portion 51,52 of Gou Chenging thus, also is provided with groove 46 for 40 li in page or leaf paper mounting portion, has more improved operability.In addition, by stiffening rib projection etc., in the loam cake being set in the part of groove 46, can also further improving its performance.
Device body 1 as shown in figure 12, protecgulum 27 is situated between and can be mounted by hinge 28 switch, when opening this protecgulum 27, just the attended operation that can exchange etc. the unit of the intermediate transfer belt 4 of inside or used toner jar TB and fixing device 14 is perhaps handled the heap paper jam in the page or leaf paper transport path in the device body 1.
In addition, device body 1 is formed for inserting the opening 29 of sheet feed stacker 21 for 27 li at protecgulum as shown in figure 13, makes and sheet feed stacker 21 (from body front) in the left and right directions of figure can be loaded and unloaded from this opening 29.Shown in Figure 13 is with sheet feed stacker 21, friction pad 23 and transport path 24 etc., the state that takes out and break away from from device body 1 along the P direction integratedly again.Thus, just can carry out standard-sized sheet to attended operation, consumables exchange, the stifled processing of heap etc. and put operation in the front of device body 1, and need not to be provided for overleaf the space of aforesaid operations, when reduction is provided with area, improve operability and image processing system cheaply is provided.
Below, slide mechanism, the locking mechanism of scanner 100 and support portion 51,52 explained.
As mentioned above, in Fig. 1 and Fig. 2 since the row's paper space between scanner 100 and the device body 1 towards the front big opening, be extraordinary for the taking-up and the visual cognition of the page or leaf paper that is discharged to 41 li of page paper mounting surfaces.
But, when the length of reduction means on the dark direction in footpath, and when attempting to reduce height, the size of front openings portion 42 also reduces thereupon, thereby can produce hand and be not easy the row's of insertion paper space, perhaps page or leaf paper is run into the convenience that has hindered page or leaf paper to take out after scanner 100 or the page or leaf paper row paper portion 25.For example in Fig. 2, because scanner 100 is also more outstanding than the rear side of image recording portion 2 and device body 1, for equipment miniaturization and after making the rear portion of scanner 100 alignment device bodies 1, front openings portion 42 will diminish.Yet, according to different users environment is set, sometimes be to come the taking-up convenience of page or leaf paper even more important compared with the size of device, sometimes because the user has different separately cognitions for the convenience that takes out, so can the size of front openings portion 42 being adjusted into, for this shift position,, just can provide suitable service condition to various users if multiple choices can be arranged.
Next, with reference to Figure 14～Figure 16, to the fore-and-aft direction of scanner 100 at device body 1, promptly page or leaf paper is discharged among direction or moving direction Xa, the Xb, has possessed as being described in detail around the support portion, the left and right sides 51,52 of the travel mechanism of the sliding support portion that can fixed support can slide.
As Figure 15 and shown in Figure 16, in the left and right sides of scanner 100, orbit portion 133,134 as sliding part is done incorporate formation, 133,134 li of each orbit portions, forms following 133a, 134a and jut 133b, 134b as slipping plane.Then, Zuo Ce orbit portion is 133 li in the drawings, is formed with along the long groove 133c that extends in the fore-and-aft direction of page or leaf paper discharge direction Xa.
As Figure 14～shown in Figure 16, following 133a, the 134a of each orbit portion 133,134 of scanner 100 be fixedly supported on and be formed at 51,52 li of each support portions, as by in top 51a, the 52a of slipping plane, can do to move.Scanner 100 loosening in the horizontal direction because between 2 pins 55 that project upwards from support portion 51 and the groove 133c that is formed at 133 li of scanner 100 orbit portions, have the chimeric of regulation slit and obtain restriction.
In the support portion 51,52 li, the portion that prevents 53,54 that comes off and above-mentioned top 51a, the 52a of the character cut in bas-relief shape in the outside form integrated respectively separately.By being formed at the portion that prevents 53,54 that comes off of 51,52 li of each support portions, and be formed between jut 133b, the 134b of prominent bar of 133,134 li on track of scanner 100, distinguish chimericly with the slit of regulation, can prevent scanner 100 coming off and float loosening upward.
In addition, also can forming in the inboard separately of support portion 51,52 comes off prevent portion in, form the jut of prominent bar by inboard at the track 133,134 of scanner 100, and between the jut of the inboard of the track 133,134 of the come off portion that prevents and the scanner 100 of each inboard of support portion 51,52, come with the slit of regulation chimeric, to prevent scanner 100 coming off and float loosening upward.
So, example according to present embodiment, because in framework (casing) lining of scanner 100 orbit portion the 133, the 134th, integrated formation, following 133a, the 134a of each track 133,134 slides with respect to top 51a, the 52a of each support portion 51,52, need not to append parts and just can reach slide mechanism at a low price.In addition, also can give orbit portion 133,134 and scanner 100 bodies with full intensity by the cross sectional shape of each track 133,134.
Owing to come off the portion that prevents 53,54 in the support portion 51,52 li be integrally formed separately, need not to increase parts and just can qurer prevent scanner 100 coming off upward.
In addition, the portion that prevents 53,54 of coming off is 51,52 the left and right sides in the support portion, can strengthen be used to bear the intensity of load in, even scanner 100 about a certain side when stressed, also can prevent floating upward.
If when not needing above-mentioned advantageous effect, also can be when scanister (scanner a 100) side sets same as described above coming off and prevents portion 53,54, in a side of support portion 51,52, sliding contact surface that will be identical with the track 133,134 of scanner 100 with have top sliding contact surface and form.
For separately support portion inside and outside both sides be provided with come off prevent portion after, the space of configuration miscellaneous part will be reduced.Owing to also need to dispose parts such as loam cake switch buffer gear in the support portion, thus with the portion that prevents that comes off that do not take up room as far as possible for well.
Here, according to the example of present embodiment,, just can reach and do not take up room and can guarantee that coming off of intensity prevents portion because the outside separately of the come off support portion, right side 51 of the portion that prevents 53,54 and support portion, left side 52 or inboard a certain side set.
The portion that prevents the 53, the 54th that comes off prevents from the 53a of portion, 54a and is arranged on coming off of 51,52 rears, support portion to prevent that the 53b of portion, 54b from cutting apart configuration by being arranged on coming off in 51,52 the place aheads, support portion.Thus, because when the place ahead of scanner 100 is stressed, coming off of the place ahead prevents that the 53a of portion, 54a from bearing this power, and when the rear of scanner 100 was stressed, coming off of rear prevented that the 53b of portion, 54b from bearing this power, so just can prevent floating upward effectively.In addition, prevent to dispose miscellaneous part in the space between the portion cutting apart coming off of configuration.
In the example of present embodiment, though because on the space or metal pattern constitute the reason of (for example the slide cores used of injection molding etc.), cut apart the portion that prevents that comes off with the place ahead of support portion and rear, also can in the full field of support portion, be provided with to come off and prevent portion.In addition, can strengthen intensity after the portion that prevents 53,54 that comes off forms box shape, further strengthen with stiffening rib etc.Thus, the intensity of the portion that prevents 53,54 that just can strengthen coming off, when the user is applied with upward power for scanner 100, fully can be in 53, the 54 li problems that damaged distortion takes place of the portion that prevents that come off.
Further, in the end separately of the divided glide direction Xb that prevents the 53a of portion, 54a, 53b, 54b of coming off, as illustrated in fig. 17, be formed with gradient 53c, when scanner 100 when glide direction Xb slides, with the tip of orbit portion 133,134 hook can not take place.As shown in figure 14, also be formed with gradient 133d in the first end of the orbit portion 133,134 of scanner 100.Thus, when preventing that when coming off the tip of orbit portion 133,134 of the end of the 53a of portion, 54a, 53b, 54b and scanner is staggered, just can prevent to have slided because of both hook hinders.
As shown in figure 17, even when scanner 100 slides into the rear of glide direction Xa, in the slip possible range of scanner 100, setting comes off and prevents the length L of the 53a of portion, makes the orbit portion 133,134 of scanner 100 be fitted to coming off of 51,52 the place aheads, support portion and prevents that coming off of the 53a of portion, 54a and rear from preventing in the 53b of portion, the 54b.Thus, the position of scanner 100 is no matter in which position in the slip possible range, because orbit portion 133,134 is to be combined in coming off of 51,52 the place aheads, support portion to prevent that coming off of the 53a of portion, 54a and rear from preventing in the 53b of portion, the 54b, just can prevent scanner 100 floating upward effectively.
When scanner 100 being assembled into 51,52 li of support portions, in Figure 14～Figure 16 and Figure 18, from being arranged on inlet 51b, the 52b at 51,52 rears, support portion, with orbit portion 133,134 insertions and (glide direction Xb) slip back arrangement forwards of scanner 100.In the support portion on right side 51 li, as Figure 14 and shown in Figure 180, be formed with excision groove 51c with the slip range equal length of scanner 100, after scanner 100 is inserted, open the loam cake 18 that is included in 26 li of superstructure bodies, when being fitted to ladder spiral pin 56 in the excision groove 51c, screw togather 134 li of orbit portions that are installed to scanner 100 from rear side.By this ladder spiral pin 56,, scanner 100 do not fall down when just can not coming off when rearward (glide direction Xa) slides.In Figure 18, being scanner 100 shown in Figure 18 (a) does not have the original state of sliding with respect to support portion 51,52, the state when to be scanner 100 shown in Figure 18 (b) with respect to support portion 51 slide into the range of glide direction Xa.Scanner 100 is taken out from support portion 51,52 throw off in, carry out and above-mentioned opposite sequence of operation, that is what at first carry out is the step that ladder spiral pin 56 is taken out from excision groove 51c.Ladder spiral pin 56 is not limited to this, also can be rivet (rivet) or stair-stepping screw etc.
Therefore, example according to this form of implementation, even because the user has applied upward scanner 100 or the power of glide direction, scanner 100 can not come off from fixed support portion 51,52 yet, thereby can realize and provide the image processing system of high reliability intensity.In addition, because scanner 100 can be easily from glide direction Xa loading and unloading, it installs removal might as well.
As shown in Figure 3, consider from security, when automatic manuscript handling device 120, when platen lid 110 is opened, the locking mechanism that superstructure body 26 can not be opened, and when opening superstructure body 26, make automatic manuscript handling device 120 and platen lid 110 locking mechanisms that can not open etc., two locking mechanisms are configured in the rear of left side fixed support portion 52.51 li of the fixed support portions on the right side of opposition side, be used for the picture signal of scanner 100 is delivered to the circuit of the electric base (not shown printed circuit board (PCB)) of device body 1 one sides, in order to have certain slack and also can be configured movably corresponding to the slip of scanner 100.
In addition, at the rear of the fixed support portion 52 in left side, also disposed the circuit that has certain slack, is used to transmit the drive control signal of automatic manuscript handling device 120 at the adjacency of above-mentioned 2 locking mechanisms.At this moment since the fixed support portion 51,52 about being divided into by drive control signal with the circuit of the picture signal of transmission scanner 100 and automatic manuscript handling device 120 so that the interference-free influence of picture signal.According to present embodiment,, settling scanner 100 can not cause the problem of clamping two circuits owing to can load and unload scanner 100 from the fixed support portion 51,52 at device rear.
As mentioned above, when employing makes the formation that scanner 100 can slide, need pin scanner 100 at the plural number place it can not be moved, be provided with the locking mechanism of scanner 100 for this reason.
As Figure 14, Figure 19～shown in Figure 21 71 li of the axial regions of action button 70, is equipped with Figure 18 and the volute spring 72 of being turned round shown in Figure 21, and it makes action button 70 be paid the gesture whereabouts device outside always.70 li of action buttons, form the 70a of hook shape, when being in the state of being turned round 72 pairs of gesture of volute spring, its excision portion 135 with 133 li on the track that is formed at scanner 100 is after closing, and the slip of scanner 100 is locked.On the one hand, when pressing the action button of exposing in fixed support portion 52 sides 70 in order to resist pair force of being turned round volute spring 72, because above-mentioned system closes and is disengaged, scanner 100 just can slide.There is plural number place (this example is 3 places) in the excision portion 135 of the orbit portion 133 of scanner 100, can lock scanner 100 in each position.
As mentioned above, scanner 100 loosening in the horizontal direction, though by protruding in fixed support portion 52,2 pins 55 shown in Figure 14, with chimericly restricting of being formed at scanner 100, groove 133c shown in Figure 15, because the fixed support portion 52 of such scanner 100 disposes various functional parts, the distance that enlarges between 2 pins 55 is limited.Also have, in order to reduce manufacturing cost, pin 55 is the plastic components with page or leaf paper mounting portion 40 and fixed support portion 51,52 integrated formation, and groove 133c is the plastic components with the integrated formation of framework of scanner 100, therefore its chimeric precision is limited, and comes easy deformation compared with metal.Thus, even under the state that the slip to scanner 100 locks, scanner 100 is with respect to fixed support portion 51,52, also has looseningly in the horizontal direction, and left and right sides balance is also bad.Also have,, can exemplify the composite material of PC (polycarbonate) and PS (polystyrene),, can suitably adopt the fire retardant that is fit to rules to handle according to the region country that uses as above-mentioned each plastic components.
In the example of present embodiment, 51 li of the fixed support portions on right side, 1 sliding locking mechanism is set in addition also, alleviate loosening on the horizontal direction thus.So, be arranged on the locking mechanism of 51,52 li of left and right sides fixed support portions, as described later,, just the influence of becoming flexible can be reduced to minimum because it is fully long apart from the size with respect to device body.
51 li of the fixed support portions on right side, as shown in figure 22, the cylinder type Lock Part 80 with coniform head is endowed upwards the force of paying because of the effect of compression spring 81 always, thereby is to close mutually with the groove 136 of 134 li of the orbit portions that is formed at scanner 100.One end (upper end) of compression spring 81 is to be combined in the spring engaging part of Lock Part 80 bottoms, the other end (lower end) by tying in the spring engaging part 51d of fixed support portion 51.The action button 70 and the Lock Part cylindraceous 80 of the fixed support portion 52 in left side connect by flexual tinsel 82 shown in Figure 21.The right part of tinsel 82 shown in Figure 21 (fixed support portion 51 1 sides), inboard from paper in figure is bent to 90 degree to the front side, in addition, in Figure 22, be bent to 90 degree from the front side of paper to the inboard, tinsel 82 is connected in the hook engaging part (right part among Figure 21) after extending from bottom to top in figure.Therefore, just can come 2 locking mechanisms of interlock operation by push button 70.In addition, tinsel 82 as shown in figure 21, by the groove (not shown) in the inner face reinforcement that is arranged on the loam cake 18 of fixed support portion 51,52 incorporate pages of paper mounting portions 40, and the guiding 57a etc. that is installed in the tinsel pressing component 57 of loam cake 18 inner faces, loosely be not directed to.About in the connection of locking, by using tinsel 82, even complicated path also can be come the interlock locking mechanism with simple and few parts.
Shown in the example of present embodiment, when clamping 51,52 li of the outstanding to the left and right fixed support portions of page paper mounting portion 40 and dispose locking mechanism,, be effective because need transmit action by U word path.
When push button 70 is turned round each pair force of volute spring 72 and compression spring 81 with opposing, because of Lock Part 80 by tinsel 82 tractives, the Lock Part of cylinder type 80 descends, its with the groove 136 of scanner 100 between be to close promptly to obtain releasing.At this moment, Lock Part 80 is shown in Figure 23 (b), and discomfort breaks away from from groove 136 fully, and conical head also is embedded in 136 li of grooves.When under this state, scanner 100 being slided,, just have " click is rattled away " sense and take place because groove 136 can be pushed Lock Part 80 downwards again.In addition, because the Lock Part 80 that is pressed down is being fashionablely also to have " click is rattled away " sense and take place with groove 136, for the user, just can feel position that the ground cognition locks.
As mentioned above, the superstructure body 26 that constitutes by scanner 100, page or leaf paper mounting portion 40 and loam cake 18, the rotating fulcrum 17 of rotation axis with the device rear is the center, rotate open so that the place ahead can be opened, so can exchange periodically parts and exchange consumables such as toner cartridge or transfer belt etc.Form in the device at illustrated 4 tandem type coloured images, when cartridge processing was disposed side by side with horizontal direction, owing to cartridge processing will be loaded and unloaded upward, superstructure body 26 just need carry out the front and back of 90 degree and rotate open.Under this state, if when mistake unlocks by the action button 70 of slide lock, scanner 100 will fall because of deadweight.In order to prevent this point, by Figure 14 and falling preventive structure shown in Figure 180 are set, though scanner 100 is come off from the fixed support portion 51,52 of device body 1 to fall down, play the effect that keeps scanner 100, but might meet the user and cause the accident of damaging owing to existing scanner 100, so be necessary to adopt following method to prevent because of falling down that maloperation causes.
That is, as shown in figure 21, near action button 70, be provided with the tilting member 75 that is installed in 52 li of fixed support portions, can in vertical direction, freely rotates.When coming together to open superstructure body 26 with loam cake 18, tilting member rotates because of its deadweight, and moves on the mobile route of action button 70.Thus, when superstructure body 26 was in open mode with loam cake 18, action button 70 was run into tilting member 75, and can not move to the position of latch-release, thereby just can prevent freely falling of the scanner 100 that causes owing to maloperation.
Next, with reference to Figure 14, Figure 19, Figure 24～Figure 31, to explaining around near opening the end that is formed at slide mechanism portion and the masking material that this is hidden.
As mentioned above, prevent for scanner 100 coming off upward, as Figure 14～shown in Figure 16, though be chimeric the finishing between the portion that prevents 53,54 of coming off in left and right sides orbit portion 133,134 by scanner 100 and the left and right sides fixed support portion 51,52, be arranged on the scanner that can slide 100 on fixed support portion 51,52 tops and hand placed the loading that it comes above can being subjected to down, be necessary to make fixed support portion (below be also referred to as " pedestal ") 51,52 in fore-and-aft direction, to extend owing to worry the user.Especially for the place ahead of the fixed support portion 52 of right-handed person's user side, can be as far as possible to come to make support above the 52a and the portion that prevents 54 that comes off.
Thus, when scanner 100 rearward being slided for the visual cognition of page or leaf paper, face 52a and come off and prevent that the 54a of portion from will reveal on the preceding upper face side of pedestal (fixed support portion) 52.If only just do not have problem above being somebody's turn to do for the plane, but because of it forms when being used to come off the chimerism that prevents as sliding support portion (below be also referred to as " slide mechanism "), above it 52a and come off prevent that the 54a of portion is exposed to outside, will produce safety on problem.
Though also can consider the chimeric shape only not done to come off and prevent in the place ahead of pedestal (fixed support portion) 52, make it only as the plane of mounting scanner 100, at this moment, this plane need be on shown in Figure 14 52a and scanner 100 below more than the sliding contact surface (below be also referred to as " interphase ") between the 133a.Talk about if not so, the surface of contact of friction slip will exceed side or front during slip.When the gap space on this glide direction exposes outside, because the possibility that can when sliding, be involved in, so on safety, exist problem hidden danger.
Here, how to realize the miniaturization of scanner 100 below the consideration.As Fig. 9～Figure 11 is illustrated, in scanner 100 inside, exist the scanning element (not shown) that reads the original copy that is placed and drive the CD-ROM drive motor 131 of this scanning element, CD-ROM drive motor 131 is situated between by being with opportunity 138 to wait and transmit this driving force, and drives above-mentioned scanning element.
The thickness of above-mentioned scanning element that is need occupy roughly all in the scanner 100 in the scope of its moving part, because CD-ROM drive motor 131 fixes, so only there is the part of CD-ROM drive motor of being provided with 131 to need height.Thus, though it is as long as the part of scanner 100 is outstanding downwards, when this position is positioned at the top of page paper mounting surface 41, the page or leaf paper that will the row of being hooked into be discharged from during paper or by in the page or leaf paper of storehouse, perhaps because and the distance between the storehouse face 41 will cause page minimizing of pile stack capability after reducing.This problem is resolved by protruding in the pedestal (support portion) 52 outside page paper discharge scope (logical paper scope).
As mentioned above, when considering the miniaturization of scanner 100, the part of scanner 100 is outstanding downwards.Keeping the above-mentioned interfacial while, when wanting to contain outstanding in this pedestal (support portion) 52, will be by keeping interfacial outer wall and being used to accommodate inner outstanding cavity and forming Figure 14 and opening difference of height 59 (hereinafter to be referred as " opening 59 ") shown in Figure 19.Opening 59 is formed at above the sliding support portion (slide mechanism) among glide direction (page or leaf paper the discharge direction) Xb 52a and comes off and prevents near the leading section of the 54a of portion in the present embodiment example.More specifically, opening 59 be by: along near the formed pair of right and left sidewall of glide direction Xa, Xb 52c, the 52d of the support portion the leading section 52; And surround along near 3 walls such as the page or leaf paper Width Y formed front side wall 52e of the support portion the leading section 52 that the back forms.So, forming integratedly continuously around the leading section of support portion 52 with pair of sidewalls 52c, 52d and front side wall 52e, is that particularly coming off prevents the intensity of the 54a of portion because need to improve the intensity of support portion 52.
This opening 59 is when forwards sliding scanner 100, and the possibility that finger is sandwiched between itself and scanner 100 front side wall increases, and has been called the significant problem on the safety.Therefore, just need a kind of user of making to operate slide mechanism portion, with the slip interlock and the masking material and the mechanism that can hide opening 59 selectively of scanner 100.
Figure 24～shown in Figure 31 is, carry out interlock with the slip of scanner 100, near the 1st position of the 52 li formed openings 59 in support portion the leading section that 3 walls that clog pair of right and left sidewall 52c, 52d and front side wall 52e fence up (below be also referred to as " hidden position "), and between the 2nd position after keeping out of the way from the 1st position (hidden position) (below be also referred to as " position of readiness "), as the curtain-shaped cover member 90 of the shifting part that can be shifted.
Curtain-shaped cover member 90 has possessed: mainly as the axial region 91a, the 91b that shake the displacement center; Maintenance shown in Figure 25～Figure 27 waits is as the 1st maintaining part 93a of the torsion spring 98 of elastomeric element; The 2nd maintaining part 93b; Limit self shake displacement shake restrictions 94a, 94b, 94c; The package portion 95 of torsion spring; Stop block 96; Be used to cover the face that covers 92,97 of opening 59, these and above-mentioned material form with plastics in the same manner.
Between axial region 91a, the 91b of curtain-shaped cover member 90, be formed with the torsion spring package portion 95 that the package shown in Figure 25～Figure 28 etc. has torsion spring 98.In in the leading section that curtain-shaped cover member 90 is assembled into support portion 52, one distolateral the 1st maintaining part 93a of curtain-shaped cover member 90 and the 2nd maintaining part of key shape passed through of torsion spring 98, sandwich with being held tying, come off prevent in, the other end of torsion spring 98 is formed on the spring engaging part 58a institute tying in the diapire of the support portion shown in the dotted line 52 among Figure 27, thus, the torsional moment of torsion spring 98 just can be delivered to 90 li of curtain-shaped cover members.
In axial region parts 91a, 91b, be provided with diameter group and want the formed oval excision of little width portion, an integrated part that is formed at the 58b of bearing portion, the 58c of support portion 52 1 sides forms towards ground, device top with the opening portion bigger a little than the width of above-mentioned elliptical section.Thus, just with axial region 91a, the 91b of curtain-shaped cover member 90 in opposite directions and the right 58b of bearing portion, 58c can insert from circumferencial direction simply.At this moment, the distolateral 98b of another of torsion spring 98 meets in the spring engaging part 58a that is formed at support portion 52 diapires back by tying.
Curtain-shaped cover member 90 is after the insertion for the 58b of bearing portion, 58c, shake for mind-set device the place ahead in shaking with axial region 91a, 91b and to be moved to usable range, at this moment, because the elastic force of torsion spring 98 is paid force, in 90 li effects of curtain-shaped cover member is the power of always occupying the direction of hidden position (the 1st position).Here, curtain-shaped cover member 90 is got back to the position of assembling beginning, for the ellipse excision portion that is formed at axial region 91a, 91b is thrown off from the 58b of bearing portion, 58c, is provided with stop block 96.Stop block 96 becomes crooked and constitutes in the pivot center direction, when curtain-shaped cover member 90 shakes displacement with axial region 91a, 91b for shaking the center, it is to close the 58d of portion to run into the back bending with the restriction of shaking that is arranged on 52 li of support portions, is not replying when the 58d of portion closes in restriction system by shaking.Thus, the ellipse excision portion among axial region 91a, the 91b can not be returned to the opening portion of the 58b of bearing portion, 58c, and curtain-shaped cover member 90 can not thrown off and not break away from opening 59 from the 58b of bearing portion, 58c.At this moment, the standby angle of curtain-shaped cover member 90 and below setting angle, becomes the condition that does not have what inconvenience in the use thus more than the angle that reality is used.
In addition, 90 li of curtain-shaped cover members, what be provided with the face that covers 92,97 that opening 59 is covered selectively and limit that this shakes shakes restrictions 94a, 94b, 94c, and its detailed action specification is as follows.
Follow the action of curtain-shaped cover member 90 of slip of scanner 100 as described below.Near under the CD-ROM drive motor 131 that is positioned at scanner 100 in the diapire of position, being integrally formed outstanding downwards is the portion of closing 139.To close portion 139 are a kind of projections in system, in the sliding scale of scanner 100, be set to curtain-shaped cover member 90 shake restrictions 94a, the 94c contour shape that closes of sliding contact system selectively respectively.
90 li of curtain-shaped cover members, be formed with and run in opposite directions and parts, what promptly be arranged on 100 li of scanners is the portion of closing 139, limits the restriction face that the shakes 94a that self shakes displacement.Scanner 100 is along glide direction Xb as mentioned above from device rear one side, install after sliding, when with scanner 100 along glide direction Xb, when sliding with pair force ground of resisting torsion spring 98, when shown in Figure 29 (b) and Figure 30 (a), being among the slip figure state, scanner 100 be the front of the portion of closing 139 run into curtain-shaped cover member 90 shake restrictions 94a, can be the center just thus with axial region 91a, 91b, shake displacement with making curtain-shaped cover member 90 clockwise direction.Then, when scanner 100 be the first end (leading section) of the portion of closing 139 run into curtain-shaped cover member shake restrictions 94a after, scanner 100 be that the rear end of the portion of closing 139 contact with the restrictions 94a that shakes of curtain-shaped cover member 90 on one side, one side curtain-shaped cover member 90 is shaken displacement along clockwise direction.When scanner 100 slides into the face foremost of support portion 52, scanner 100 be that the rearward end of the portion of closing 139 is promptly closed and pushed with the restrictions 94a system of shaking of curtain-shaped cover member 90, and curtain-shaped cover member 90 also occupies the position of readiness shown in Fig. 8, Figure 29 (b) and Figure 30 (a).
At this moment, the back side of the back side of scanner 100 and image recording portion 2 is equal to, and machine is of a size of minimum.So, when carrying out bale packing under curtain-shaped cover member 90 occupies the state of position of readiness, because concavo-convex few, just do not need to use in large quantities bale packing materials, in addition because the bale packing volume is little, a upwards of movement of truck also obtains increasing, and is also beneficial concerning environmental protection.Owing to use ladder spiral pin 56 (with reference to Figure 16) to install, scanner 100 can not thrown off on direction of insertion loading and unloading direction, scanner 100 just can be from the support portion 51,52 come off.
Action when next, scanner 100 being slided into the rear position explains.In order to improve the taking-up of row's paper, with scanner 100 when glide direction Xa slides, scanner 100 slips move into place in the position shown in Figure 30 (b) in rearmost end, curtain-shaped cover member 90 shakes the hidden position that is moved among the figure.At this moment, as Figure 30 (b) and shown in Figure 31, each contour shape is set to scanner 100 be in the portion of closing 139, the bottom raised face of rear end among the figure, only closing sliding contact with the restrictions 94c system of shaking of curtain-shaped cover member 90, is that the front end raised face on right side in the portion of closing 139, among the figure and the restrictions 94a that shakes of curtain-shaped cover member 90 are in contactless state.Also have at this time, as being exposed to outer only be this figure and the face that covers 92 shown in Figure 22, opening 59 is hidden and is occupied by covering face 92 basically.
In other words, curtain-shaped cover member 90 shakes the face that covers 97 that sense of displacement is provided with vertical plane with respect to this, we can say that this formation of covering face 97 is that opening 59 is exposed outside.Thus, because the user is pressed into shaking on the sense of displacement when no longer worrying to run into 97 li in the face of covering, in the screening effect that can keep curtain-shaped cover member 90, can prevent the breakage of curtain-shaped cover member 90.
That is the shape that hides the face that covers 92 of opening 59 in the curtain-shaped cover member 90 is to be the face of barrel surface of same axial region 91a, 91b based on the central shaft that has and shake.Thus, accommodate curtain-shaped cover member 990, and the slit that is formed between near 52 leading sections of support portion the opening 59 just need not open very greatly, in addition, the slit in shaking on the way can be very not big yet.Cover face 92 in order to prevent dropping of clip etc., in each sliding position, continuous to adopt, and opening 59 between the constituting of the curved surface that constitutes of the circumference of gap below 1mm.
Also have, the shape of covering face 92 is not limited to barrel surface, also can be have with the central shaft that shakes be the axial region 91a of same axle, the sphere of 91b.
In addition, the front side wall of covering face 97 and scanner 100 is identical shaped, when the position of the glide direction Xa that slides into the rear, because pair force of torsion spring 98, be that the center is shaken along counter-clockwise direction and pushed to axial region 91a, 91b, run into the front side wall of scanner 100.Thus, sidewall 52c, 52d near the leading section of support portion 52, a pair of and the slit between front side wall 52e and the opening 59 become very little, the user does not just worry that finger can be sandwiched, and can prevent dropping of clip etc. when guaranteeing security yet.
Make that only paying force the face that covers 92 of curtain-shaped cover member 90 is shaken when rising, finger may be stretched into wherein when the user pushes curtain-shaped cover member 90, had the slit also might have thing to drop down later on by pushing to of torsion spring 98.Therefore, in the present embodiment, shown in Figure 24 and Figure 30 (b), shaking restrictions 94c is in the rear end face of the portion of closing 139 by what run into scanner 100, though its constitute the face of covering 92 can opening by user pushing yet.At this moment, shake the effect that restrictions 94c plays and be, when curtain-shaped cover member 90 occupies hidden position, be urged even cover face 92, himself can displacement yet push the portion of preventing.Shake restrictions 94c as what push the portion of preventing,, also can be described as double as and limited self the displacement restriction portion of shaking displacement by being that the portion of closing 139 closes with what be arranged on 100 li of scanners selectively.
Here, though write up the shape of the face that covers 92,97 in the curtain-shaped cover member 90, its shape is not limited to this.For example, so long as in the scope that intensity allows, also can be the front side wall 52a that removes support portion 52, suitable with it shape be formed on curtain-shaped cover member one side gets final product.In the above-described configuration, though be to be applicable to the situation of slip fixed position when determining occasion, even with slipping plane be with flat shape simultaneously, also can obtain same effect, just can cover opening thereby be not limited to sliding position.
In addition, if the loosening up and down deviation that slide to constitute is few, be the precision of shaking restrictions 94c of portion of closing 139 and curtain-shaped cover member 90 by what improve scanner 100, even without torsion spring 98, also can suppress the slit in the hidden position of Figure 30 (b).
Yet loam cake 18 is that the center can be opened upward and constituted with rotating fulcrum 17.This loam cake 18, as illustrated in fig. 3, the operation cover lock is decided the operating portion 61 of means 60, and when being the center rotation with rotating fulcrum 17, Jie is rotated together by the light scanning apparatus 8 of fixed support portion 51,52, scanner 100 and bottom.Then, the inside of device body 1 is presented, and just can begin from the front each unit that image forms has been operated, and as previously mentioned, also can easily carry out for operations such as maintenances.
When rotating this loam cake 18,,, might cause platen lid 110 also to be rotated simultaneously along with the opening of loam cake 18 because the axis of the rotating fulcrum 17 of loam cake 18 and the hinge 111 of platen lid 110 is parallel.
At this moment, in the image processing system of present embodiment,, below be its explanation even be provided with the locking means 170 that open loam cake 18 also can carefully be opened platen lid 110.
In Figure 32～Figure 37, locking means 170 comprise, are arranged on 110 li on platen lid, with the Lock Part 171 of engaging part 140 tyings; Locking intermediate member 175 with removable cover Lock Part 171; Decide the action component 178 of intermediate member 175 with the action cover lock.
Locking intermediate member 175 is formed by the sheet material of strip, is provided with back shaft 176 in one side of its long side direction, and being situated between can be supported on 100 li of scanners rotationally by this back shaft 176.In addition, in the another side of long side direction of locking intermediate member 175, be provided with outstanding upward action pin 177 in the one end, 177 174 li of action movies that are connected to Lock Part 171 are sold in this action.Also having, 171 li of Lock Parts, is the center with rotating fulcrum 172, action movie 174 by spring 171a pay gesture towards with the rotating force of action pin 177 closures.Constitute by this, action pin 177 was guaranteed with being connected of action movie 174.
Though this locking intermediate member 175 is that rotate at the center with back shaft 176, the elder generation of its rotation is distolateral to be located on the overshooting shape 179 that is formed at 178 li of action components because of deadweight.Action component 178 is as Figure 32～shown in Figure 38, and an end is situated between can be installed in 18 li of loam cakes rotationally by axle 180, and the other end is set to move along the track 182 that is arranged on 1 li of device body.Overshooting shape 179 be formed at the axle 180 basically identicals concentric circles on.
Figure 39 is under the state shown in Figure 3, from installing the enlarged drawing of a left side part of seeing in the front.At first, in loam cake 18 the insides,, the upper ledge 45 of pair of right and left is installed in the both sides of light scanning apparatus 8.45 li of these upper ledges, connecting the both ends of rotating fulcrum 17.Rotating fulcrum 17 cause device body 1 on the rear side of device body 1 supports.Thus, for device body 1, superstructure body 26 (loam cake 18, scanner 100) is the center with rotating fulcrum 17, switch freely is mounted, when opening to above reverse angle, what bear conversely because of the effect of gravity is the moment of torsion of opening on the direction, makes the superstructure body open, and image recording portion 2 opens to the outside.In addition, in the two end portions of the rotating fulcrum of giving prominence to from upper ledge about 45 17, an end hooks into device body 1 one sides, and the other end hooks into superstructure body one side, as to open in the superstructure body direction pay gesture pay the gesture parts, be provided with by the rotation axis spring 47 that constituted by torsion spring etc.
Here, because exchange cartridge processing etc., loam cake 18 is center when opening upward with rotating fulcrum 17, and as shown in figure 39, after the other end of action component 178 moved along track 182, action component 178 had erected.At this moment, action component 178 is the clockwise rotation of center along Figure 38 with axle 180, and after the teat of projection 179 left locking intermediate member 175, its circular portion joined with it.Then, locking intermediate member 175 is that rotate along clockwise direction at the center with back shaft 176, and Lock Part 171 is the center with rotating fulcrum 172 simultaneously, is rotated by inhour, lock pawl 173 and engaging part 140 tyings cover 110 lock-out state and enter Figure 35～platen shown in Figure 37.
So, when open loam cake 18, with this opening operation linkedly, it is 110 locked that the platen of scanner 100 covers.Therefore, the platen of loam cake 18 and scanner 100 lid 110 is together from front face side, when promptly Zhuan Zhi face side begins to operate, even be situated between by the rotating fulcrum of rear side by open, because the opening of loam cake 18 makes the opening of platen lid 110 obtain stoping.Thus, just can eliminate the problem that makes loam cake 18 breakages because not noting opening platen lid 110.
In addition, locking intermediate member 175 is that the center is when being rotated with back shaft 176, because as long as this face is in Figure 32～position that tilts upward shown in Figure 34, and shake between the position of the basic horizontal of Figure 35～shown in Figure 37 and get final product, in Figure 32～position shown in Figure 34, though be to join with projection 179 and maintained,, in the casing of scanner, be provided with stop block (not shown) downwards so that it can not rotate again at Figure 35～place, planimetric position shown in Figure 37.Thus, locking intermediate member 175 both can be the projection 179 of running into action component 178 in the position of the basic horizontal of Figure 35～shown in Figure 37, also can be to leave a little.Further, owing to be provided with stop block, make locking intermediate member 175 can below the scanner 100 of slipping plane, not fly out downwards, just can prevent to carry out level and smooth slip because of the slipping plane that flies out.
In the above-described embodiment, no matter the position of scanner 100 how, that is, no matter where scanner 100 is slided into, though because the opening of loam cake 18 can prevent being opened of platen lid 110, when but platen lid 110 is opened, can not prevent mistakenly that loam cake 18 is open.
So, in this image processing system, when platen lid 110 is in open state, being provided with the locking mechanism that stops cover unit 18 to be opened, it is described as follows.
In Figure 40 to Figure 42, to decide in cover lock the left end of fulcrum 62 of means 60, an end of relaying bar 265 is fixed, and by the operation of operating portion 61, relaying bar 265 also rotated when fulcrum 62 rotated.In the other end of relaying bar 265, join with the pin 267 that is installed in an end of the slide unit 266 that slides on the fore-and-aft direction of device.266 li of slide units, from the place ahead of page or leaf paper mounting portion 40 is the rod unit of long size to the rear, be formed with the slotted hole 268 of elongation in the bearing of trend after its central authorities lean on slightly, the guide roller 43 that is installed on 42 li of frames that are arranged on 18 li of loam cakes arranged in that 268 li of this slotted holes are chimeric, by this formation, the glide direction of slide unit 266 and slip width obtain restriction.Then, between frame 42 and slide unit 266, be provided with back-moving spring 269 to the sliding force at 266 pairs of gesture whereabouts of slide unit rear.By this back-moving spring 269, slide unit 266 as shown in figure 43, its rear end is maintained in the position of the framework of running into loam cake 18.In addition, during rotating operation portion 61, relaying bar 265 is to close with pin 267 mutually, and slide unit 266 promptly is pulled to the front face side of device.Then with hand when operating portion 61 is decontroled, by back-moving spring 269, slide unit 266 turns back in the position shown in Figure 43.Also have, consider the tolerance or the alignment error of parts, under loam cake 18 closing state, to leave plurality of gaps between pin 267 and the relaying bar 265 for well.By this formation, slide unit 266 can not be subjected to the interference of relaying bar 265, and the rear end of slide unit 266 just can be run in the framework of loam cake 18 effectively.
The rear end of slide unit 266, that is in the opposition side of an end that is provided with pin 267, be formed with described later, with latch-release parts 271 be mutually close, outstanding is to close protuberance 270 upward.Latch-release parts 271 are and have certain thickness strip, and axis is a long side direction, is the center with the rotating fulcrum in the avris that is arranged on short side direction 273, can be installed in 100 li of scanners rotationally.271 li of these latch-release parts, be formed with above-mentioned system close protuberance 270 be close, the cross section be rectangle be to close recess 272, this is to close recess 272 to be 3 in the present embodiment.
