Image read-out has usually implements light-struck light source to the paper spare original copy of discharging by Zhang Luxu of original copy automatic conveyor, and the imageing sensor of the reverberation of being returned by the surface reflection of paper spare original copy being implemented reception.

But, in recent years the original copy automatic conveyor that is arranged on image read-out is required to make miniaturization, lightness, and the few device of part count.As this device, if for instance, in the open communique of No. 179271/1987 patent of invention of Japan, disclose a kind of paper discharge roll that is provided with at place, paper spare manuscript reading section dead astern, and paper spare original copy is expelled to this class device that paper is discharged the pallet place by this paper discharge roll.This device reduces to greatest extent and transmits the needed roll quantity of paper spare original copy because shortened the transfer path of paper spare original copy, a kind ofly can realize miniaturization, lightness thereby constitute, and the few manuscript handling device of part count.

In above-mentioned this device, be that testing agency with test paper part original copy is arranged on and reads position between position and the paper discharge roll to what paper spare original copy was implemented to read, this class testing agency normally comprises level type sensor mode (level type transducer) and reflection sensor detection mode (reflection sensor), wherein level type sensor mode is by being arranged on the detection lever in the drive access, utilization is shaken paper spare original copy, paper spare original copy is implemented to detect, the reflection sensor detection mode utilizes reflecting plate that the light that the light emission part produces is reflexed to light receiver, and paper spare original copy is implemented to detect from the mode of the light of light emission part emission by the blocking of paper spare original copy.

Yet, discharge in the mode of configuration detection mechanism between the roll in paper spare manuscript reading section and paper, if a kind of level type testing agency before adopting, because the paper spare original copy leading section that is in the process of reading can be collided with lever under free state, so have because the percussion that produces when colliding, and make the image that reads out produce the problem that distortion is arranged with lever.

Particularly, if imageing sensor adopts when being the magnification optical system types such as closing type of automatic focus type lens, because it is very little that its depth of focus is compared with the scaled-down version optical system, so not only can produce picture distortion, be difficult to the problem that enforcement is read to image but also have.

And, a kind of after employing, when promptly adopting reflection-type sensing detection mode, have the light that goes out by the light emitted in the reading mechanism and may make transducer produce the problem of error detection.

Particularly, if imageing sensor adopt be the scaled-down version optical system of the light that exposes to paper spare original copy surface being implemented to read by several speculums the time because the luminous quantity of light source is bigger, so that the frequency of error detection appears in transducer is more.

Summary of the invention

Even purpose of the present invention just provides a kind of image read-out miniaturization, lightness of making, can the paper spare original copy that is in reading state not produced impact yet, thereby can obtain the image read-out of good image.And, the present invention also aims to provide a kind of can preventing that the paper spare original copy implementation mistake that is under the delivery status is detected, thereby can implement the image read-out of detection reliably to paper spare original copy.

A kind of image read-out provided by the invention, its device have implements the drive access of transmission successively to the paper spare original copy that is positioned on the paper supply tray; Implement the reading part that reads to being arranged on described original image in the drive access; Described reading part is implemented to move original image is implemented the opto-electronic conversion mechanism of opto-electronic conversion; Harvesting is discharged pallet by the paper of the paper spare original copy that the reading part place discharges; Be arranged on along direction of transfer and be positioned at the second transmission roll that first of reading part front side is transmitted roll and is arranged on its rear side; Be configured in described first first testing agency that transmits the roll upstream side; And be configured in second testing agency that transmits the more close paper discharge of the mutual crimping point pallet side position place of roll than a pair of second.

And second testing agency has and is discharging in the pallet side position than the second more close paper of crimping point that transmits roll, combine with paper spare original copy leading section also can produce shake, be the tabular lever part that hangs down.

Reading part in the image read-out of present embodiment is by can two optically read mechanisms that two the lip-deep original images of paper spare original copy that be transmitted are implemented to read being constituted.

Wherein the first optically read mechanism 20 is received and is contained within the lower component 2, and to the guide roll that is being provided with continuously along drive access 10 to 16 and the pass through paper spare original copy of central roll between to 17 implement to read by the original image of pressing plate 21.In the first optically read mechanism 20, dispose scaled-down version optical system transducer, and have first load bearing component 22, second load bearing component 24.These two load bearing components 22,24 are implemented to drive by not shown motor, and on one side and mutually interlock and the keeping relative distance of being scheduled to concerns that the left and right directions in the figure moves.

Carrying light source 25 at load bearing component 22 places, and receiving reverberation 25 that launch by light source, that reflect by paper spare original copy place, and be converted into the catoptrical speculum 26 of along continuous straight runs paper spare original copy emission irradiates light.In addition, carrying and to be converted to vertically catoptrical speculum 28 by speculum 26 reverberation reflection, along continuous straight runs at load bearing component 24 places, and will be converted to along continuous straight runs but the catoptrical speculum 29 opposite by reverberation this mirror reflects, vertically with the light direction that reflects by speculum 26.

In addition, the first optically read mechanism 20 by be fixed within the lower component 2, by collector lens 30 by the light of speculum 29 reflection, and receive by collector lens 30 and implement to focus on catoptrical charge-coupled device (CCD) type imageing sensor 31 after handling.By this charge-coupled device (CCD) type imageing sensor 31 detected light, after being converted to digital signal by charge-coupled device (CCD) substrate 32, by implementing the control basal plate (not shown) of various image processing, be sent to be positioned at input/output interface substrate place such as within photocopier etc.

In the present embodiment, the first optically read mechanism 20 can be used to read such as thicker paper spare original copys such as books.Promptly, be provided with at the upper side place of lower component 2 with described paper spare original copy by pressing plate 21 adjacent, place the reading parts that paper spare original copy uses (below be also referred to as " books read table top ") 35, the paper spare original copy that is placed on this books reading part place can be implemented scanning by the mode that moves described load bearing component 22,24, and its content is implemented to read.For this reason, the place is provided with the extruder member 7a with elastic force below described paper is discharged pallet 7, so that can to implement extruding flexibly fixing to being placed on paper spare original copy that books read table top 35 places.

Within the top assembly 3 that constitutes this image read-out 1, be provided with the second optically read mechanism 40, this second optically read mechanism 40 is used for implementing to read with the original image of the paper spare original copy opposing face side of being implemented by the first optically read mechanism 20 to read.The second optically read mechanism 40 is configured in the drive access position of shape linearly of 17 downstream side paper being discharged the upstream side of pallet by central roll, with read by paper spare original copy by on the pressing plate 21 read X1 place, position, by the image of the opposite side surfaces that picks up the paper spare original copy that guide member 38 picks up.

In the present embodiment, the second optically read mechanism 40 disposes times imageing sensors such as closing type.Specifically be to constitute by contact-type imageing sensor (CIS) assembly; receive the light source that is equipped with original image emission irradiates light in contact-type imageing sensor (CIS) assembly; this irradiates light of transmission and the catoptrical cover glass that reflects by paper spare original copy, and the reverberation transmission cover glass, that reflected by paper spare original copy implemented the scanning line style imageing sensor that detects.Be converted to digital signal by scanning line style imageing sensor detected light by circuit substrate 41,, be sent to the input/output interface substrate place that is positioned at such as within the photocopier etc. subsequently by the image processing substrate of being located within the aforesaid lower component 3 33.

Below the form of the composition that reads guide in the second optically read mechanism 40 is specifically described.

Fig. 3 is the expression amplification profile that read in drive access major part relevant with the second optically read mechanism 40.Using times imageing sensors such as closing type at second optically read mechanism 40 places.As mentioned above, times imageing sensor such as this closing type is compared with the scaled-down version optical system, and its depth of focus is smaller, so guarantee to stablize closely the advancing property of advancing when need closely contact with reading face on the paper spare original copy.What therefore, the gap of the paper spare original copy drive access in this reading part need be set is narrower.And, can within this narrow drive access, smoothly advance in order to make paper spare original copy, preferably times imageing sensors such as closing type are configured in linearly position in the drive access.Therefore, in this embodiment of the present invention, as times imageing sensors such as closing type of the second optically read mechanism 40, be configured in the drive access position of shape linearly of paper in 17 the downstream side being discharged the upstream side of pallet by central roll.

Adopt this form of the composition, just can be after the surface (reverse side among the figure) on utilizing 20 pairs of paper spare original copys of the first optically read mechanism implement to read, utilize and transmit guide member 47 and read X2 place, position what paper spare original copy guided to second reading device.In addition, utilize another surface (front among the figure) on 40 pairs of paper spare original copys of second reading device to implement to read.

Read X2 place, position at second reading device 40, be provided with have to described reading mechanism side implement extruding, such as the pressing mechanism 49 of spring etc. pick up guide member 46 so that the paper spare original copy that sends can be remained within the quite narrow permission depth of focus scope of the second optically read mechanism.

According to Fig. 4, this form of the composition of picking up guide member 46 is described below.Pick up guide member 46 and can implement to be the support of quick condition by pressing mechanism 49.Transmit guide member 47 and implementing fixed support with respect to the device chassis.Therefore, transmitting guide surface and picking up connecting position place between guide surface, can be formed with step.

This step can be in paper spare original copy running face pick up guide surface, when transmitting guide surface and more project to the running face side, the occasion for to implementing such as the relatively thinner paper spare original copy of spines such as slim paper spare original copy to read tends to occur problems such as paperboard.In contrast, this step pick up guide surface when to transmit guide surface low, the rear end of paper spare original copy tends to again form and impacts and make reading images produce distortion by this step the time.

Therefore, be provided with and read guide member 48, it by described transmission guide member 47 places, guides to paper spare original copy as what read the position and picks up flat board member 43 places.So, read guide member 48 and can preferably adopt the pliability filling component to constitute this guide member 48 that reads for this reason corresponding to transmitting guide member 47 and the described step generation change in location of picking up 46 generations of guide member.An end side that reads on the guide member 48 is installed in described transmission guide member 47 places.And a this end side that reads on the guide member 48 extends to by the outstanding central roll in the paper spare original copy transmission plane place that transmits guide member 47 the side face place on 17.In addition, picking up guide member 46 can be made of the standard white plate of implementing the shielding correction.

Described to read on the guide member 48 another distolateral by extending under free state before the described image reading position always, and elimination will be with respect to transmitting that guide surface relatively move and according to the step of picking up between two guide surfaces that guide surface produces corresponding deflection.And, picked up flat board member 43 and pick up guide member 46 by spring-supported, by slidably being supported on the front and back position place of paper spare original copy direction of transfer, eliminate scope thereby can increase step.

Fig. 5 is the plane graph of picking up guide member of expression from the upside observation second optically read mechanism 40 as shown in Figure 4.In order to transmit guide member 47 and to pick up between the guide member 46 and eliminate step, be provided with four clampings central roll to 17 read guide member 48.And, be formed with the projection 51 of implementing the gap restriction in order to keep the interval of 40 in the paper spare original copy and the second optically read mechanism.Projection 51 can be limited in than in the littler scope of predetermined gap picking up guide member 46 by what read that spring 49 on the guide member 48 implements pushing.

In addition, at downstream side place as Fig. 3 described in detail second optically read mechanism 40, dispose paper and discharge roll 50, this paper discharge roll to 50 effect under, implemented to read the paper spare original copy of processing, and be expelled to paper by paper spare original copy outlet 6c and discharge pallet 7 places.And, in the present embodiment, constitute paper and discharge roll two of 50 rolls against each other, be a kind of edge separately rotating shaft direction and imageing sensor read that width equates substantially or implement to extend the monolithic devices roll of fixing along the length direction longer than this direction, and prevent that extraneous light from passing through paper spare original copy outlet 6c, invade and to read X2 place, position to the second optically read mechanism 40.Therefore, even adopt be subjected to easily that extraneous light disturbs, such as times imageing sensors such as closing type etc. as optical pickup device, also can not be subjected to the influence of extraneous light, so will can not be subjected to the interference of noise signal by the detected analog signal of charge-coupled device (CCD) type imageing sensor, and then can correctly implement aforesaid image processing operations.

In addition, can adopt the level type transducer to discharge transducer 63 as the paper spare of test paper part original copy end, and collide and when producing percussion according to the original copy of the paper spare in being in the process of reading leading section and detection lever 63b as described below, the also mode that can not exert an influence to the image that reads, it is arranged on paper discharges roll, promptly be arranged on paper spare original copy outlet 6c place 50 downstream side.

This paper spare is discharged transducer 63 by the sensor main body 63a with light emission part and light receiver, and is formed with an end of being hung down by paper spare original copy outlet 6c and is used to block by the detection lever 63b of the light emission part on the sensor main body 63a to the other end of light path between the light receiver and constitute.Utilize guide roll to 16, central roll to 17 and paper discharge roll to 50, collided in a paper spare original copy that is in the process of reading and an end of detecting on the lever 63b, and detect lever 63b along direction shown in the arrow among Fig. 3 by making, with sensor pin 63c is that the strong point is implemented mobile mode, utilize the other end of detecting on the lever 63b that the light of being launched by the light emission part on the sensor main body 63a is implemented blocking, thereby the leading section of paper spare original copy is implemented to detect.

What suppose here to discharge that transducer 63 adopts for paper spare is the occasion of reflection sensor, implements to block to 50 because the light that is gone out by the light emitted in the reading mechanism is discharged roll by paper, so can not make transducer produce error detection.

Yet, in the present embodiment, if dust or dust etc. are attached to light emission part, light receiver and reflecting plate place, because reflection sensor can not carry out reliable detection to paper spare original copy, so need to implement periodic maintenance, what therefore adopt here is the level type sensing mechanism.

Can implement to drive to each roll in the top assembly 3 by two drive motor (not shown)s, its form of the composition can be supplied with motor M1 for unusable paper and transmit motor M2 to guide roll 16, central roll 17, the 50 enforcement drivings of paper discharge roll to picking up roll 11, separate roll 12a, write down roll 14 enforcement drivings, using.

As shown in Figure 2, the record transducer 61, helical pitch transducer 62 and the described paper spare that are provided with test paper part original copy position at drive access 10 places are discharged transducer 63 etc., the detection signal that the controlling organization (not shown) can provide according to these transducers, to the activation record roll to 14, guide roll to 16, central roll to 17, paper discharges roll to 50 etc. motor, to the action of the move operation of aforesaid load bearing component 22,24, and the light source that is arranged on each optically read mechanism 20,40 place lighted action, extinguishes action etc. and implement to control.

Fig. 6 is for being illustrated in during aforesaid paper spare original copy reads the time diagram chart of the operate time of each transducer and each motor.

In Fig. 1 and Fig. 5, the load cell (not shown) is placed on paper supply tray 5 places at paper spare original copy, and when implementing paper spare original copy reading command, can make paper supply with the motor forward drive and rotate, thereby a piece of paper spare original copy is come into effect supply.Within the certain hour of implementing after the leading section of a piece of paper spare original copy is supplied with, detected by record transducer 61 to paper spare original copy (t1), paper is supplied with motor and is rotated further, so that the leading section of paper spare original copy is collided to 14 with the record roll and produced deflection.Stop paper subsequently and supply with the rotation of motor and through certain hour (t2) afterwards, implement backwards rotation, the activation record roll moves so that a piece of paper spare original copy is sent to downstream side to 14.Then, when detecting a piece of paper spare original copy leading section, stop the rotation that paper is supplied with motor by helical pitch transducer 62.Transmit motor and when detecting paper spare original copy leading section, be rotated further, stop operating when arriving certain hour (t4) by helical pitch transducer 62.Subsequently time for reading is implemented to adjust, begin action is implemented to read in one on paper spare original copy surface by the first optically read mechanism 20.Transmit motor to a piece of paper spare original copy enforcement transmission in statu quo by using, implement to read by another surface on 40 pairs of paper spare original copys of the second optically read mechanism.

For a piece of paper spare original copy is being implemented in transmission, the process of reading, load cell continues to detect the occasion that has second later paper spare original copy in the paper supply tray, after the scheduled time (t3) after the rear end of a piece of paper spare original copy is passed through the record transducer, begin second paper spare original copy implemented to supply with.Adopt this form of the composition, just can guarantee between a piece of paper spare original copy and second paper spare original copy, to have predetermined interval.Subsequently, the leading section of 61 pairs of second paper spare original copys of record transducer is implemented to detect, and paper spare original copy leading section and record roll are connected to 14.Adopt this mode, just can implement to supply with and transmit control according to the mode identical to second each later paper spare original copy with a piece of paper spare original copy, in the process of second paper spare original copy being implemented supply with, transmit, a piece of paper spare original copy can be discharged roll by paper and be implemented to discharge to 50.At this moment, can discharge the mode of the rear end enforcement detection of 63 pairs of paper spare original copys of transducer, confirm that paper spare original copy has been expelled to paper and has discharged pallet 7 places by paper spare.

In addition, by the process scheduled time (t4) after the rear end that detects second paper spare original copy at paper spare discharge transducer 63, whole paper spare original copys have been expelled to the situation enforcement affirmation that paper is discharged pallet 7 places, and have stopped driving each motor enforcement.
