Abstract
The invention relates to a thin sheet conveying device, which comprises a driving unit selectively rotating along a first direction and a second direction. The thin sheet conveying device can lower the frequency of rotation halt due to conveying stop instructions from external devices such as an image reading part during rotation periods except when the driving unit must be stopped for a rotating direction change. Whether a motor rotates in this or that direction, a drawing-out roller (114) rotates towards a constant direction by means of a mechanism. When paper is conveyed to a discharging roller (125) position, a control part makes the motor rotate in a reverse direction instead of a forward direction. Thus, the paper is conveyed through a coordinated conveying path (131). If the paper reaches the drawing-out roller (114) position, then the control part makes the rotation of the motor temporarily stopped. During the motor stop period, the control part performs an inquiry on whether the paper can be conveyed to the image forming device or not.

No. 6 expression electrical motors 140 of Fig. 8 carry out forward again, and screw actuator 127 is with the situation of driven voller 126 liftings.Control part 101 makes after magnetic clutch 148 becomes coupled condition, is in the situation of " 2 " or " 3 " in the value of variable C, controls by making electric current flow through screw actuator 127, and driven voller 126 is risen.In addition, at this moment, control part 101 makes the hand of rotation of electrical motor 140 change to positive veer from reverse direction.At this moment, the hand of rotation of pull-out roll 114 and distributing roller 125 is opposite sense, but because driven voller 126 rises, therefore remove the towards each other state of opposite sense pulling of paper, and the position at distributing roller 125 and driven voller 126 can not sandwich paper, resistance reduces, and paper P1 is carried by pull-out roll 114.
In No. 6 of Fig. 8, when control part 101 made the hand of rotation of electrical motor 140 change to positive veer from reverse direction, the electrical motor 140 of reverse temporarily stopped its rotation, afterwards to the forward direction rotation.The control part 101 of sheet-conveying device 10 in the timing that electrical motor 140 stops the rotation, utilizes Department of Communication Force 103 and the Department of Communication Force 183 of image processing system main body to communicate, and the conveying of inquiry paper begins and carries the indication that stops, and obtains the inquiry result.Control part 101 works as an example obtaining the unit that the present invention relates to.In addition, in the image processing system 100, comprising at least the part of image reading unit 40 except sheet-conveying device 10, is to comprise image reading unit at an example of interior external device (ED).
For example, in image processing system 100, in the processing speed of the each several part of the image processing system 100 main bodys processing speed not as good as sheet-conveying device 10, perhaps produce paperboard or the situation of the bad problem of communicating by letter under, even the possibility that paper sheet delivery to image reading position, has problems is also very high.Therefore, in the situation that produce this problem, control part 181 is for the inquiry from sheet-conveying device 10, the indication that utilizes Department of Communication Force 183 to sheet-conveying device 10 notices the conveying of paper to be stopped.If the control part 101 of thin slice delivery section 10 utilizes Department of Communication Force 103 to obtain this notice, then stop to make the conveying of paper to stop by the rotation that makes electrical motor 140.Then, if the problems referred to above are removed, then control part 181 utilizes the indication that Department of Communication Force 183 begins the conveying of paper to sheet-conveying device 10 notices.If control part 101 utilizes Department of Communication Force 103 to obtain this notice, then make electrical motor 140 to the forward direction rotation.Below, to above-mentioned inquiry different the describing regularly in conventional example and the present embodiment.
Fig. 9 is the figure regularly that communicates by letter in the expression conventional example and control part 181 image processing system 100.Fig. 9 (a) and Fig. 9 (b) all temporarily stop the rotation of reverse direction at electrical motor 140, then to the forward direction rotation and the timing of conveyance of sheets is inquired to the control part 181 of image processing system 100 main bodys.Fig. 9 (a) is illustrated in and returns the inquiry result when answering for the first time is the situation of the notice of OK, and this OK represents not have problems, and can begin the indication of the conveying of paper.In this case, electrical motor 140 keeps its state to continue to the forward direction rotation.On the other hand, Fig. 9 (b) is illustrated in and once returns the inquiry result is the situation of the notice of NG, the indication that this NG represents to make owing to having problems the conveying of paper to stop.In this case, control part 101 temporarily stops the rotation of electrical motor 140, until obtain the notice of OK.Thus, the conveying of paper also stops.Then, if solution removes, then the control part 181 of image processing system 100 utilizes Department of Communication Force 183 to return the notice of OK to thin slice delivery section 10.Thus, control part 101 makes electrical motor 140 to the forward direction rotation, again begins the conveying of paper.
Like this, in the prior embodiment, owing to the timing that is transferred at paper is inquired to the control part 181 of image processing system 100, the paper that therefore can produce in the conveying temporarily stops, and again begins the state of carrying after solution removes.In sheet-conveying device 10, if the paper that is transferred temporarily stops, then when again beginning to carry, the front end of paper is stuck in transport path sometimes and causes paperboard.Therefore, wish that except the MIN timing of necessity, the conveying of not carrying out paper stops after the conveying of a paper of beginning.Relative with it, in the present embodiment, as described below.
The figure of Figure 10 timing that to be expression communicate with the control part 181 of image processing system 100 in the present embodiment.Figure 10 (a) and Figure 10 (b), all timings in electrical motor 140 stops the rotation are inquired to the control part 181 of image processing system 100 main bodys.Figure 10 (a) is illustrated in and returns the inquiry result when answering for the first time is the situation of the notice of OK.In this case, control part 101 makes the electrical motor 140 that stops to the forward direction rotation.Thus, again begin the conveying of paper.On the other hand, Figure 10 (b) is illustrated in once to return and inquires that the result is the situation of the notice of NG.In this case, because electrical motor 140 is in and stops, so control part 101 makes it continue standby, until obtain the notice of OK.Then, if solution removes, then the control part 181 of image processing system 100 utilizes Department of Communication Force 183 to return the notice of OK to thin slice delivery section 10.Thus, control part 101 makes electrical motor 140 to the forward direction rotation, again begins the conveying of paper.
Like this, in the present embodiment, because when the hand of rotation of electrical motor 140 is changed into positive veer from reverse direction and its rotation timing of advancing to stop temporarily, carry the inquiry that begins and carry the indication that stops, carry the indication that stops even therefore receiving, because electrical motor 140 has stopped, and also can not make the conveying of paper repeat to stop.Thus, except the timing that temporarily stops in order to make electrical motor 140 change its hand of rotation, again begin the action of carrying after the paper in being difficult to carry stops, therefore be not easy to produce paperboard.
In addition, in No. 6 of Fig. 8, if at electrical motor 140 during the reverse direction rotation, the front end of paper arrives the position of pull-out roll 114, then control part 101 is when the hand of rotation that makes electrical motor 140 is changed into positive veer from reverse direction, the rotation of electrical motor 140 is temporarily stopped, but make this stop regularly to be following timing.That is to say, contact with pull-out roll 114 at paper, and, the front end of this paper is on common transport path 130, be positioned at the sheet transport direction downstream of comparing with connecting part 137, and be positioned at when stopping the scope of the sheet transport direction upstream side that roller 117 is compared, control part 101 stops the rotation of electrical motor 140.Later on this scope is called stop area.If paper detects the front end of the paper that transports at collaborative transport path 131 by sensor 116, then notify this situation to control part 101.Control part 101 is after receiving this notice, if the timing time of timing section then makes the driving of electrical motor 140 stop through predetermined time.The so-called schedule time, refer to after detecting the front end of paper by paper by sensor 116, until the front end of paper is positioned at the required time of stop area, its rotative speed based on electrical motor 140 reaches and pre-determines by the distance of sensor 116 to stop area from paper.
Owing to when the front end of paper is positioned at stop area, stopping to carry, therefore having following advantage.For example, connecting part 137 easily makes paper stop up at the part place of its joint.If stop the conveying of paper when the front end of paper is positioned at the upstream side of sheet transport direction of connecting part 137, when then again beginning the conveying of paper, the front end of paper easily is stuck on the connecting part 137 and causes paperboard.Therefore, when being positioned at the downstream of sheet transport direction of connecting part 137 by the front end at paper the rotation of electrical motor 140 is stopped, and suppress paperboard.
In addition, if when the front end of paper is positioned at the downstream that stops roller 117, stop the conveying of paper, then become paper by the state that stops that roller 117 sandwiches.For example, in the situation that produce paperboard, the user makes top carry guide part 135 to the direction rotation of carrying guide part 136 away from the bottom, after becoming open mode, sheet-conveying device 10 takes out paper, if but were in paper by the state that stops that roller 117 sandwiches, then can produce the user will be by the trouble that stops the paper taking-up that roller 117 sandwiches by manual manipulation.Relative with it, the rotation of electrical motor 140 is stopped owing to being positioned at the front end of paper when stopping the sheet transport direction upstream that roller 117 is compared, therefore suppress paper and be blocked roller 117 and sandwich.In addition, at this moment, paper also is clipped between pull-out roll 114 and the driven voller on the other side 115, but make conveying guide part 135 in top to the direction rotation of carrying guide part 136 away from the bottom, and when making sheet-conveying device 10 become open mode, pull-out roll 114 separates with driven voller 115, thereby becomes the state of not clamping paper.
Again return Fig. 8.After No. 6 of Fig. 8, again carry out the action identical with the action of explanation in No. 3 of Fig. 7, No. 4 of Fig. 7, No. 5 of Fig. 8, No. 6 of Fig. 8.When the action of finishing No. 5 of Fig. 8 for the 2nd time, the value of variable C becomes " 3 ".When the action of carrying out No. 6 of Fig. 8 for the 2nd time, the value of variable C is " 3 ", can carry next paper.Therefore, the rear end that detects paper P1 by sensor 116 from paper, through after predetermined time, control part 101 makes magnetic clutch 148 become notconnect state, and makes magnetic clutch 143 become coupled condition.Thus, feed rolls 113 and paper are drawn in roller 111 to the forward direction rotation, and next paper P2 is carried.Like this, control part 101 switches by the transmit mode to the propulsive effort of magnetic clutch 148 and magnetic clutch 143, and the conveying of control paper regularly.And control part 101 is with the value zero clearing of variable C.
No. 7 expression paper P1 of Fig. 8 are in discharging the way, and the situation of next paper P2 and feed rolls 113 butts.If paper detects the front end of paper P2 by sensor 116, then notify this situation to control part 101.Control part 101 after receiving this notice, if by time of timing section timing through predetermined time, then make magnetic clutch 148 become coupled condition, and make magnetic clutch 143 become notconnect state.
Paper P1 is discharged in No. 8 expressions of Fig. 8, and the situation of carrying next paper P2.Because magnetic clutch 148 is coupled condition, so pull-out roll 114 rotates to the graphic direction of arrow, and P2 carries to paper.Paper P1 carries by discharging conveying roller 125, discharges to discharging paper mounting portion 12.
Like this, according to present embodiment, control part 101 makes electrical motor 140 to the forward direction rotation, begin to carry out from supplying with the conveying of the 1st paper of supplying with the position, at the 1st paper at common transport path 130 by behind the position of feed rolls 113, utilize electromagnetism to close device 143 and switch to the state that does not carry out transmitting from carrying out propulsive effort to the state of the transmission of feed rolls 113.In addition, control part 101, at the 1st paper at common transport path 130 by behind the position of pull-out roll 114, utilize magnetic clutch 148 to switch to the state that does not carry out transmitting from carrying out propulsive effort to the state of the transmission of pull-out roll 114.In addition, if the 1st paper is delivered to the position of distributing roller 125 at common transport path 130, then control part 101 makes electrical motor 140 change the hand of rotation of distributing roller 125 to the reverse direction rotation, makes the 1st paper be delivered to the position of pull-out roll 114 via collaborative transport path 131.And control part 101 utilizes magnetic clutch 148 never to carry out propulsive effort and switches to the state that transmits to the state of the transmission of pull-out roll, and control part 101 stops the rotation of electrical motor 140.And at the stopping period of electrical motor 140, control part 101 begins and carries the indication that stops to the conveying of the control part 181 inquiry paper of image processing system 100.If obtaining the inquiry result is the indication that the conveying of paper stops, then control part 101 makes electrical motor 140 standbies, until obtain the indication that the conveying of paper begins.On the other hand, be the indication that the conveying of paper begins if obtain the inquiry result, then control part 101 makes electrical motor 140 to the forward direction rotation, and the hand of rotation of distributing roller 125 is changed.And, if the 1st paper is by the position of pull-out roll 114, then control part 101 utilizes magnetic clutch 148 to switch to the state that does not carry out transmitting from carrying out propulsive effort to the state of the transmission of pull-out roll 114, on the other hand, utilize magnetic clutch 143 never to carry out propulsive effort and switch to the state that transmits to the state of the transmission of feed rolls 113, the conveying of the 2nd paper that will carry after the 1st paper is begun.And, until the 2nd paper via image read the position be delivered to distributing roller 125 the position, undertaken by electrical motor 140 be rotated in the forward during, carry the 1st paper and discharge by distributing roller 125.
According to present embodiment, having selectively in the sheet-conveying device 10 of the electrical motor 140 of positive veer and reverse direction rotation, when stopping in order to make electrical motor 140 change its hand of rotation, the conveying that obtains paper begins and carries the indication that stops.Thus, during the rotation can be in the time must stopping in order to change its hand of rotation except electrical motor 140, suppress to stop to indicate owing to the conveying from image processing system 100 frequency of the chance that stops its rotation.In addition, because for the hand of rotation that makes electrical motor 140 changes to positive veer and timing that control part 101 temporarily stops the rotation of electrical motor 140 from reverse direction, become the front end of paper when transport path 130 is positioned at the sheet transport direction downstream of comparing with the connecting part 137 of top conveying guide part 135 and bottom conveying guide part 136 usually, therefore in the time of can being suppressed at the conveying that again begins paper, the front end of paper hangs on the connecting part 137 and causes paperboard.In addition, because for the hand of rotation that makes electrical motor 140 changes to positive veer and timing that control part 101 temporarily stops the rotation of electrical motor 140 from reverse direction, the front end that becomes paper is positioned at when stopping the sheet transport direction upstream side that roller 117 is compared at common transport path 130, therefore when the conveying that stops paper, can form paper and can not sandwich the state that stops between roller 117 and the driven voller 118.Thus, when the user will take out owing to the paper that paperboard is stopped up, can save will be by the trouble that stops the paper taking-up that roller 117 sandwiches by manual manipulation.
