Embodiment
Below, the form of implementation that present invention will be described in detail with reference to the accompanying.
(the 1st form of implementation)
Serve as reasons image that image processing system with sheet material processing apparatus of the present invention and image read-out constitutes of Fig. 1 forms the sectional drawing of disposal system.
In Fig. 1, symbol 100 is for having the printer of image reading unit 200, carrying out image with paper and forms the back and set 2 discharge paths what supply with from paper feeding cassette 101.At first, for use paper to be transported to the top that writes scanner 104, A transfer passage 105 and the direct B transfer passage of carrying 106 that overturns and carry by photographic fixing exit roller 102, pair of rollers 103 by u turn.
In addition, sheet material processing apparatus 300 will be discharged to sheet material mounting outside the machine from printer body 100 after the 1st preloading portion 301, align by alignment unit 302, to each predetermined printed document, sheet material is become to stack, bind at 1 position or a plurality of position at this sheet material, discharges to be deposited into the 2nd preloading portion 303, or only be to face down or discharge the 2nd preloading portion 303 that is deposited into faceup.
Below, the formation of sheet material processing apparatus 300 is described and is sent to the action of each one of the occasion of sheet material processing apparatus 300 from the sheet material S that printer body 100 is carried.
In Fig. 1, at sheet material processing apparatus 300 row of setting paper top roll 330a, row's paper lower roll 330b, make rubber-like blade 321 that sheet material moves towards alignment direction, be used for benchmark wall 322 that the sheet material rear end is positioned.
Here, as shown in Figure 1, the exit roller that is made of row's paper top roll 330a and row's paper lower roll 330b turns round driving to 330 by driving motor M1 described later.In addition, row's paper top roll 330a is bearing in as exit roller supporting member 331 that can rotating roller supporting member.
In addition, in this form of implementation, this exit roller carries out so-called interconnected as shown in Figure 2 to 330, make to enter between each roller body as roller body 330a1, the 330a2 of row's paper top roll 330a of the 1st roller with as roller body 330b1, the 330b2 of row's paper lower roll 330b of the 2nd roller.Like this, row's paper top roll 330a does not contact with row's paper lower roll 330b, becomes so-called broach and constitutes.In addition, row's paper top roll 330a and row's paper lower roll 330b overlap in the axial direction.
Overlap by the row's of making paper top roll 330a like this and row's paper lower roll 330b, thereby when discharging sheet materials (stacking) by exit roller to 330, sheet material (stacking) produces and rises and falls the rigidity enhancing of sheet material (stacking) here.As a result, though sheet material (stacking) by exit roller to 330 after, also do not discharge as the crow flies towards below deflection ground.In addition, this rigidity is strong more when row's paper top roll 330a is big more with the overlapping amount of arranging paper lower roll 330b, and when rigidity increased like this, the distance of discharging as the crow flies increased.
As shown in Figure 2, the past more respectively outside of the roller body 330b1 diameter at the both ends that are contacted with sheet material of row's paper lower roll 330b forms more bigly, like this, becomes the formation at the both ends of lifting sheet material (stacking).
By making sheet material (stacking) have rigidity, increasing the distance of discharging as the crow flies, simultaneously, lift the both ends of sheet material (stacking), even the amount of bow and the discharge direction of the sheet material of discharging from printer body 100 change with the different of photographic fixing pattern, printing mode with the paper kind, in addition, no matter whether carried out bookbinding handle, when discharging sheet material (stacking), the front end that also can prevent this sheet material (stacking) is contacted with the sheet material (stacking) of having discharged, can improve preloading.
On the other hand, slide-and-guide member 302a described later, 302b drive by rushing paper motor M, in this form of implementation, use stepping motor.In addition, constitute by flexible materials such as rubber as the blade 321 of alignment unit, at sharf 350 along fixing a plurality of with the direction of sheet material throughput direction orthogonal.When printer body 100 is discharged sheet materials, towards revolution counterclockwise, like this, sheet material S is contacted with benchmark wall 322 towards moving with sheet material throughput direction reverse direction as alignment direction, aligns by the driving of sharf 350.
In addition, such as shown in Figure 3A, in the sheet material processing apparatus 300 of this form of implementation, the alignment member as the alignment of the Width that carries out sheet material is arranged on the slide-and-guide member 302a and the slide-and-guide member 302b that describe in detail later.M is for rushing the paper motor as drive source, in addition, in Fig. 3, H orders the conduct of sewing processing and orders the attachment means of sewing the unit for stacking at sheet material to thread a needle and sheet material stacked, this attachment means H threads a needle for the upper left bight at the image surface of the sheet material that has formed image, each sheet material ordered sew, fixed configurations is in slide-and-guide member 302a side.
, in this form of implementation, this sheet material processing apparatus 300 can carry out preloading alignment, the bookbinding of sheet material in preloading portion 301, discharges preloading in the 2nd preloading portion 303, or only is to discharge preloading in the 2nd preloading portion 303 by facing down or facing up.
Below, illustrate by facing down sheet material is discharged the simple stacking action of preloading in the 2nd preloading portion 303.In occasion, such shown in Fig. 4 A, relatively the position that does not contact the sheet material S that sends into is kept out of the way in the sheet material input direction bottom surface that is in the slide-and-guide member 302b in the slide-and-guide member 302a on right side and left side, i.e. the position of the past outside scheduled volume of the Width of the sheet material S of supporting sheet S not.
Therefore, by the inlet roller to the 362 sheet material S that carry by after the scope of attachment means H, carry 330 by the exit roller that comprises row's paper top roll 330a and row's paper lower roll 330b, shown in the arrow of Fig. 4 B, fall towards the 2nd sheet material discharge portion 303 like that.
Below, illustrate behind 301 preloadings alignment of preloading portion and bookbinding sheet material and discharge preloading in the action of the 2nd preloading portion 303.In this occasion, but slide-and-guide member 302a, the 302b sheet material S that sends into of mounting like that as shown in Figure 3A waits in not waiting the position with the sheet material side end is interfered.In the present embodiment, in the size (width) of sheet material S maximum sized occasion,, make the gap of both sides become the position of waiting of scheduled volume d ground setting slide-and- guide member 302a, 302b respectively as showing like that of Fig. 3 B for leading to paper.
In addition, at this moment, the interval of the end face of the bottom surface of 2 slide-and- guide member 302a, 302b is in the position littler than the width of sheet material S.By making 2 slide-and- guide member 302a, 302b be in such position, can constitute the 1st preloading portion 301 that the sheet material S that enters is supported to the sheet material guide part between 330 with benchmark wall 322 and exit roller.Therefore, 362 sheet materials of carrying are passed through to be carried 330 by exit roller after the scope of attachment means H, be transported on the spigot surface of the preloading portion 301 that constitutes by slide-and- guide member 302a, 302b by the inlet roller.
On the other hand, as Fig. 5 A, after the 1st sheet material just has been transported on the face that is formed by slide-and- guide member 302a, 302b, such shown in Fig. 5 A, exit roller supporting member 331 turns round toward the clockwise direction, like this, the row's paper top roll 330a that is supported on exit roller supporting member 331 direction up keeps out of the way, and exit roller is to separating.
In addition, meanwhile, cut off to be connected to exit roller to 330 driving, the row of making paper top roll 330a and the revolution of arranging paper lower roll 330b stop.When the rear end of sheet material S breaks away from the inlet roller to 362 the time fully, blade 321 with sharf 350 be the center towards revolution counterclockwise, time turn around with being contacted with above the sheet material S.Like this, sheet material S is contacted with benchmark wall 322, finishes the alignment action of throughput direction.
Then, the only slide-and-guide member 302b in left side action, preloading is in the alignment action beginning of the Width of the sheet material S of the 1st preloading portion 301.Specifically, slide-and-guide member 302b drives by rushing paper motor M, moves towards the right side of Fig. 4 A, thereby makes slide-and-guide member 302b be contacted with the left end of sheet material S, and sheet material S is pushed into slide-and-guide member 302a side.
Then, the right-hand end of sheet material S is contacted with slide-and-guide member 302a, thereby carries out the alignment of the Width of sheet material.Sheet material S is moved at sheet material be contacted with slide-and-guide member 302a and the gutter pos ground setting of positions aligning setting.After the alignment action, slide-and-guide member 302b moves towards the direction than the width broadening of sheet material S, can wait the conveying that next sheet material is tackled in the position once more.
Here, in order to keep the state of alignment like this, nearby be provided as the cramping unit 380 of holding unit in the right part of the sheet material of aligned condition, this cramping unit 380 as the A of Fig. 3 A to shown in Fig. 3 of view C like that, move down up by the bar 380b that is provided with friction member 380a, pushing sheet material S remains in the precalculated position with it.
This cramping unit 380 has towards upper and lower to rotating bar 380b.After finishing the alignment action, next sheet material that enters is contacted with before the sheet material of alignment, by not shown solenoid the bar 380b after the top is turned round is turned round towards the below, shown in Fig. 3 C, push above the sheet material like that, thereby by entering of next sheet material the sheet material of aligned condition is moved, prevent the disorder of aliging.
After the alignment of carrying out the 1st sheet material like this finishes, carry the 2nd sheet material, but when carrying the 2nd later sheet material, exit roller separates 330, so, after deviate from 362 from the inlet roller fully the rear end of sheet material S, before beginning the alignment action, cramping unit direction up moves, and finishes to keep action.After this alignment action is identical with the 1st, so, omit explanation.
Then, carry out such action repeatedly, carry out the alignment action of last (n sheet) sheet material (Sn) of 1 printed document, make the left end of sheet material be contacted with slide-and-guide member 302b, under the state of Fig. 6 A that moves that stops slide-and-guide member 302b, the position that sheet material stacks the right side, rear end is bound by attachment means H.
On the other hand, when such end bookbinding action, like that, exit roller supporting member 331 is towards revolution counterclockwise shown in Fig. 5 B, thus make be supported on exit roller supporting member 331 row's paper top roll 330a down direction move, form exit roller to 330.After this, driving is connected in exit roller to 330 roller both sides, begins to arrange the revolution of paper top roll 330a and row's paper lower roll 330b.
Then, drive simultaneously with this action and to rush paper motor M revolution, thereby the direction that the interval from state shown in Fig. 6 A and the 6B towards slide-and- guide member 302a, 302b enlarges moves.After this, the width that the interval of two slide-and- guide member 302a, 302b is in sheet material is nearby or when wideer than it, be supported on sheet material that the bookbinding of slide-and- guide member 302a, 302b is through with and stack drop to the below like that shown in Fig. 4 B and Fig. 5 B, preloading is in the 2nd preloading portion 303.
Explanation makes sharf 350 rotating formations and makes the row's paper top roll 330a direction formation of keeping out of the way up that is supported on exit roller supporting member 331 according to Fig. 7～Figure 12 A and 12B below.
Fig. 7 illustrates the gear series of the row of transmitting drive to paper top roll 330a and the gear series of the row of transmitting drive to paper lower roll 330b.In Fig. 7, symbol 505 is for being fixed in row's paper upper roll gear of the axle 505a that arranges paper top roll 330a, and symbol 506 is roller gear under the row's paper that is fixed in row's paper lower roll 330b.In addition, by being with 504 to accept driving, roller gear 506 is from accepting driving by idling gear 503 with row's paper lower roll idling gear 508 of driving (be set to disengage gears 404 same axis on) under row's paper from idling gear 503 for row's paper upper roll gear 505.In addition, when by A-stage shown in Figure 7, exit roller supporting member 331, is made of with not shown stopper element towards the mutual approaching direction application of force of roller contiguously spring P, by this stopper element row's paper top roll 330a is positioned, the regulation exit roller is to 330 clamp amount.
In addition, this driving series also comprises blade 321 and separates driving system with roller except the feed drive system of driving row paper top roll 330a and row's paper lower roll 330b.Here, feed drive system accepts revolution from the motor gear 501 of the axle that is fixed in driving motor M1, drive installation in exit roller to 330, the input roller of gear 513 is right to 2 rollers of 362, feeding sheets.
In addition, but blade 321 separate with roller and drive system by 1 drive force revolution as drive source drives motor M2 drive electric motor gear 401 by rotating.Then, make swinging mounting 450 swings as oscillating structural member, but this swinging mounting 450 free rotaring ground supporting change gear 403 and turriform gear 402, and be spot wobble with oscillation centre 450a, this change gear 403 is used for selectively drive transmitting with driving motor M2 to blade 321 or exit roller supporting member 331, this turriform gear 402 and motor gear 401 engagements.Like this, change gear 403 selectively is connected to disengage gears 404 and lamina idle-run gear 406, the driving that this disengage gears 404 has by driving motor M2 makes exit roller to 330 hypodontia gear 404a (aftermentioned) and the cam wheel 404b (aftermentioned) that separate, and this lamina idle-run gear 406 arrives blade 321 with the drive transmitting of driving motor M2.
In 450 certain friction force of effect of turriform gear 402 and swinging mounting, when turriform gear 402 turns round along with the revolution of motor gear 401, make swinging mounting 450 swings here, by the revolution of this turriform gear 402.In this form of implementation, when swinging mounting 450 turned round towards counter clockwise direction, change gear 403 was connected in disengage gears 404 and transmits driving, and when swinging mounting 450 was swung toward the clockwise direction, change gear 403 was connected to lamina idle-run gear 406 and transmits driving.
In addition, in Fig. 7, supporting drive transmitting gear 502 and can oscillation centre 550a be that the driving of center swing is removed plate 550 by spring 555 application of force toward the clockwise direction.When exit roller supporting member 331 makes exit roller separate 330, relieving rod 331a pushing drives removes plate 550, thereby remove drive transmitting gear 502 towards the drive transmitting that is disposed at the idling gear 503 on the sharf 350, thereby remove to exit roller 330 driving.
Constitute drive transmitting portion 500 by these change gear 403, disengage gears 404, lamina idle-run gear 406 and the relieving rod 331a that is located at exit roller supporting member 331.
Below, make row's paper top roll 330a action of keeping out of the way of direction up of the drive transmitting portion 500 of such formation according to Fig. 8 A and 8B～Figure 11 A and 11B explanation.Fig. 8 A and 8B illustrate the illustrated state that has omitted blade gear 407 and blade 321.
