2. Description of the Related Art As a document reading device in a copying machine, a facsimile or the like, a sheet document is automatically conveyed to a document reading position to read document information, and the read document is automatically ejected from the document reading position. An automatic document feeder (ADF) is known.

As described above, when the original is a sheet original, the ADF is mounted so that the original information can be automatically read. However, when the original is a book original, automatic page turning is performed. Since it is difficult to realize the mechanism, at present, the pages of the book manuscript can be turned only manually. On the other hand, conventionally,
Although various proposals have been made for methods and means for automating the troublesome reading of book originals, many of these conventional techniques have only ideas, and have not reached the level at which they can be realized. In light of these circumstances, the present application
As disclosed in, for example, Japanese Patent Application No. 2-193589, a person separates a part of a page-turning belt stretched along the document placing surface of the document placing table from the document placing surface. While forming the detour portion, the page storage means, the page suction means, the page separation means, and the reading are performed on the document surface of the book document that is opened and placed between the document mounting surface and the page turning belt. There has been proposed a page original reading apparatus for book originals which performs page turning of the book original and scanning for reading the original by relatively moving a page turning reading unit provided with means and the like.

According to the page turning reading apparatus for book originals according to this proposal, as described in the above-mentioned specification and the like, the page turning operation and the original reading scanning of the book original, which requires a great deal of labor for the copying work and the like, are performed. It is possible to realize a multifunctional original reading system which can be completely automated and remarkably improves productivity such as copying.

[0005]

SUMMARY OF THE INVENTION By the way, in the page turning reading apparatus for book originals previously proposed by the present applicant, the original pages separated from the page turning belt are rolled into a substantially cylindrical shape and stored in the page storing means. By storing the original pages, the original pages are turned, and by moving the page turning reading unit, the original pages are discharged from the page storing means. Therefore, in this page turning reader of the book original, in order to make the entry of the original page into the page storing means smooth at the time of turning the page, the tip of the page entry guide portion of the page receiving means is turned in the page turning direction. It is desirable that the sheet be formed so as to extend in the vicinity of the document surface so as to follow the. However, as described above, when the leading end of the page entry guide portion of the page storage means is formed so as to extend to the vicinity of the document surface along the page turning direction, the original stored in the page storage means is formed. When ejecting a page, the ejected original page is caught at the tip of the page entry guide section, and the original page cannot be ejected smoothly from the inside of the page storage unit, or the original page cannot be ejected forcibly. There was a problem that it was damaged. Therefore, the page storing means is composed of a page storing member and a page turning guide, and is configured so that the page turning guide enters while rotating along the inner peripheral surface of the page storing member, A method has been proposed in which the above-mentioned inconvenience is eliminated by retracting the page turning guide upward when the document page is discharged. However, in this method, the radius of curvature of the part of the page turning guide that enters the page storage member is set smaller than the radius of curvature of the inner peripheral surface of the page storage member, but The radius of curvature is set to be larger than the radius of curvature of the inner peripheral surface of the page storage member. Further, since the center of rotation of the page turning guide is the center of the page storage member, the rotation of the page turning guide causes the end portion of the document guide portion to largely swing. Therefore, in such a page storing means, it is necessary to secure a space in the page turning reading unit that allows the rotation of the page turning guide, which causes a new problem that the page turning reading unit becomes large. There is a drawback to invite.

The present invention has been made in view of the above points, and an object thereof is to discharge a book document at the time of discharging.
An object of the present invention is to provide a highly reliable page turning apparatus for book manuscripts, in which the space for disposing the page accommodating means can be reduced, and manuscript pages can be smoothly discharged from the page accommodating portion.

The drive mechanism and drive control means of the page-turning reading unit 1 have been described in detail in the above-mentioned prior application, and therefore the description thereof is omitted here.

The configuration and operation unique to the present embodiment, which is different from the MFDS of the prior application, will be described below.

In the page turning reading unit 1, as shown in FIG. 5, various rollers 6, 7, 8, 9, 10, 11, 12 are rotatably provided between a pair of front and rear unit side plates 5. It is supported. Here, the belt supporting rollers 6, 7 and 8 serve as a belt detouring section forming means 300 that separates a part of the page turning belt 200 from the document placing surface 100a and forms the detouring section 200a on the page turning belt 200. It is functioning. Also, the turning roller 9
The separating roller 10 functions as the page separating unit 700 that separates the original pages adsorbed by the page turning belt by the curvature of the page turning belt 200 at the portion facing the page storing port 500a of the page storing unit 500. . Further, the charging roller 11 and the counter electrode roller 12 function as page attracting means 600 that charges the page turning belt 200 with an unequal electric field to attract the pages of the book original O to the page turning belt 200.

Further, in the bypass portion 200a of the page turning belt 200, the reading portion 4 is provided with respect to the original placing surface 100a.
00a are opposed to each other, and the reading unit 40 is arranged on the document reading scanning direction (arrow a direction) side of the bypass 200a.
The reading sensor 13 and the reading sensor control board 14 as 0, and the page storing port 500a are opened in the page turning direction (direction of arrow b) opposite to the document reading scanning direction of the bypass 200a, and the reading unit 400 is opened.
On the other hand, a page storage member 15 as the page storage means 500 and a page turning guide 16 are arranged in parallel along the document scanning direction.

Further, riding guides 17 and 18 supported between both unit side plates 5 are provided at the end portion on the reading scanning direction side and the end portion on the page turning direction side of the page turning reading unit 1, respectively. There is. The riding guides 17 and 18 are located on the opposite side of the book original O with the page turning belt 200 interposed therebetween, do not come into direct contact with the book original O, and are usually the page turning belt 2
00, and when the page turning reading unit 1 moves in the reading scanning direction shown by the arrow a in FIG. 3, and in the page turning direction of the page turning reading unit 1 shown by the arrow b in FIG. It has a function of smoothing the vertical movement of the page turning reading unit 1 with respect to the document surface of the book document O during movement.

The lifting and lowering of the page-turning reading unit 1 at this time is carried out by a lifting mechanism 800 with an inclination preventing function. The lifting mechanism 800 is composed of a link mechanism as shown in FIGS. That is, in FIG. 6 to FIG. 8, one end of each of the first link 21 and the second link 22 is rotatably rotatably supported at the end of the studs 19 and 20 for fixing the riding guides 17 and 18 to the unit side plate 5. Has been done. The other ends of the first and second links 21 and 22 are respectively rotatable by the stepped screws 23 and 24 so that one ends of the third link 25 and the fourth link 26 and both ends of the side link 27 are rotatable. It is pivotally supported. The other ends of the third link 25 and the fourth link 26 have studs 28, 29, respectively.
Are rotatably supported by the unit driving side plates 30. Further, a guide pin 31 is fixed to the outside of the unit side plate 5.
Is vertically movably fitted in a long groove 32a of a unit elevating guide 32 arranged inside the unit driving side plate 30.

According to the elevating mechanism 800, when the page turning reading unit 1 reciprocates, the thickness of the book document O causes each of the riding guides 17 and 18 to receive a force from each traveling direction, so that the riding is carried out. Due to the upward component force acting on the guides 17 and 18, the page turning reading unit 1 is lifted without tilting (FIG. 8). Further, according to the elevating mechanism 800, the guide pin 31 fixed to the outer side of the unit side plate 5 is moved up and down along the long groove 32a of the unit elevating guide 32 arranged inside the unit drive side plate 30. It is possible to prevent the skew of the page turning reading unit 1 when the page turning reading unit 1 is moved up and down, and the vertical movement of the page turning reading unit 1 does not change the document scanning speed of the reading sensor 13. Stable image scanning is realized.

The lifting mechanism of the page turning reading unit 1 may be constructed as shown in FIGS. 9 and 10.

In FIGS. 9 and 10, unit upper and lower rods 34 are fixed to two upper and lower rod fixing plates 33 formed on the unit driving side plate 30. Two upper and lower unit upper and lower guide plates 35 formed on the unit side plate 5 are slidably fitted to the unit upper and lower rods 34. According to the elevating mechanism configured as described above, since the upper and lower unit upper and lower guide plates 35 slide along the unit upper and lower rods 34, the page turning reading unit 1 is moved up and down. Even if a rotational moment acts when the unit 1 is moved up and down, the page turning reading unit 1 is smoothly moved up and down, and the configuration is simplified.

On the other hand, the page turning reading unit 1
Is reciprocally driven in the reading scanning direction and the page turning direction by reciprocally driving the unit driving side plate 30 described above. As shown in FIGS. 11 to 13, the unit drive plate 30 has three guide members 36 formed on the outside thereof fitted in the guide rods 37, so that the unit drive plate 30 can be moved in the left-right direction in FIGS. 12 and 13. , Is slidably supported. The guide rod 37 is provided on the document placement surface 10
Two parallel side plates are provided on the front and rear side plates of the upper unit 2 in parallel to the front end 0a, and both ends of each side plate are fixed. Further, the unit driving plate 30 is integrated with a timing belt 39 stretched between the guide rods 37 by a fixing plate 38 formed on the outside thereof. As shown in FIGS. 12 and 13, the timing belt 39 is rotatably stretched by a drive pulley 40 and a driven pulley 41 pivotally supported by the front and rear side plates of the upper unit 2, and is driven by a drive motor 42. Each drive pulley 40 is rotationally driven via the driven drive shaft 43 to be reciprocally rotationally driven. In this way, the timing belt 39 is driven to reciprocally rotate at a predetermined timing, so that the page turning reading unit 1 is operated as shown in FIG.
As shown in FIG. 4 and FIG.
It is reciprocated along the document surface.

By the way, the page rake angle θ of the page turning guide 16 in the page storing opening 500a of the page storing means 500 is set so that the book original O separated from the page turning belt 200 by the page separating means 700 enters the page storing opening 500a. It is necessary to make the angle smaller than the angle α so as to eliminate the document separation error. That is, as shown in FIG. 14, when the page turning roller 9 and the separation roller 10 are arranged at the same height, the page of the page turning guide 16 in the page storing port 500a of the page storing means 500 is shown. The rake angle θ1 is the entry angle α of the book document O separated from the page turning belt 200 by the page separating means 700 into the page storage port 500a.
Configured to be smaller than. In this case, the page rake angle θ1 of the page turning guide 16 is preferably 60 degrees or less, and more preferably 10 degrees or less. Page rake angle θ of this page turning guide 16
1 depends on the turning margin with respect to the material of the page of the book document O, and when the document page is soft, the entry angle α into the page storage port 500a becomes relatively large, so even at an angle of about 60 degrees, it is separated. It is possible, and when the original page is hard, the entry angle α into the page storage port 500a becomes relatively small, so it is preferable that it is as small as 10 degrees or less.

However, as shown in FIG. 14, when the turning roller 9 and the separating roller 10 are arranged at the same height, the page turning guide 1
In order to reduce the page rake angle θ1 of 6, it is necessary to bring the lower end portion of the page turning guide 16 close to the document placing surface 11a. If the edge of the book document O rises for some reason when the reading unit 1 moves in the page-turning direction, the lower edge of the page-turning guide 16 may come into contact with the edge of the book document O. Therefore, in the page turning reading unit 1 of this embodiment, as shown in FIGS. 5 and 15, the separation roller 10 is more than the height of the turning roller 9.
By increasing the separation position of the book document O separated from the page turning belt 200 and increasing the substantial entry angle α1 of the document page into the page storage port 500a. The lower end of the page turning guide 16 can be sufficiently separated from the original placing surface 11a, and the page rake angle θ2 of the page turning guide 16 can be sufficiently reduced.

As a result, the uppermost page of the book original O, which is attracted to the page-turning belt 200 and is curvature-separated by the separating roller 10, passes through the page-storing port 500a and the page-turning guide 16 as shown in 1F of FIG. Is guided to the inside of the page storage member 15 and is stored in the page storage member 15 while being wound in a cylindrical shape along the inner peripheral surface of the page storage member 15.

Here, the entry direction of the uppermost page separated by the separation roller 10 into the page storage port 500a is
As described above, since the entry angle α1 into the page storage port 500a differs depending on the quality of the original pages to be separated, it does not always follow the page turning guide 16. Therefore, in the page turning reading unit 1 of this embodiment, as shown in FIG.
A page guide 15a is formed at an outer peripheral portion of the page turning guide 16 facing the page turning guide 16 so that the uppermost page separated by the separation roller 10 enters the page storage port 500a regardless of the quality of the original pages to be separated. Is forcibly deflected in the direction along the page turning guide 16.

Further, in the page turning reading unit 1 of this embodiment, as shown in FIG.
By arranging the facing plate 44 in close contact with the back side of the page turning belt 200 between the separating roller 10 and the separating roller 10,
It was confirmed as a result of an experiment that the original page suction force of the uneven electric field pattern formed on the page-turning belt 200 is increased and the reliability of page-turning is improved. here,
In this embodiment, the facing plate 44 is made of a metallic plate material. However, the facing plate 44 does not necessarily have to be made of a conductive member such as metal, and the same effect can be obtained by using an insulating member. was gotten.

Further, as the page separating means 700, instead of the above-mentioned turning roller 9, as shown in FIG. 16, a diameter R2 sufficiently larger than the radius R1 of the turning roller 9 (in this embodiment, The reliability of page turning is further improved by adopting a structure in which the turning support plate 45 having a curved surface of R2 = 75 mm is arranged. Here, the surface curvature ρ of the turning support plate 45 is ρ = 1 / R2 =
1/20 or less, that is, the diameter R2 of the turning support plate 45 is 20 mm or more, preferably 60 mm or more. Such a page separating means 700 can be dealt with by setting the radius R1 of the turning roller 9 to be 20 mm or more. However, if the radius R1 of the turning roller 9 is increased in this way, the page turning reading unit 1 becomes large. It causes trouble.

As shown in FIG. 17, the surface of the turning support plate 45 is closer to the separation roller 10 nearer the edge, that is, in the direction of entering the page into the page storage port 500a of the page storage means 500. By configuring the curvature to gradually increase, the original page is turned over against the waist strength of the original page.
Since the force to bend the paper is gradually increased with respect to the original page, the followability of the original page to the page turning belt 200 is increased, and the reliability of the page turning can be further improved. . FIG. 17 of the present embodiment.
The page-turning support plate 45 shown in FIG.
From the contact point G1 that first contacts the book document to the separation point G2 where the suction-separated document page is curvature-separated from the page turning belt 200, the diameters R3, R4, and R5 are
R3 = 100 mm, R4 = 70 mm, R5 =
It is configured to change in three stages of 40. Here, the turning support plate 45 may be configured so that its surface curvature continuously changes.

By the way, the examples shown in FIGS. 15 to 17 show the page separating means 700 in which the separating roller 10 is fixedly arranged in advance so that the height of the separating roller 10 is higher than the height of the turning roller 9. However, as the page separation means 700, as shown in FIGS. 18 to 21, the separation roller displacement means 900 may be configured to displace the separation roller 10 at a predetermined timing. As shown in FIG. 19, the separating roller displacing means 900 in this embodiment is composed of a pair of a turning lever 46, a turning solenoid 47, and a return spring 48. As shown in FIG. 19, each turning lever 46 is formed in an L-shape, and its corners are rotatably supported by both ends of the support shaft of the turning roller 9. The separating roller 10 is rotatably supported by the free ends of the turning levers 46 extending in the horizontal direction. Further, at the base end portions of the turning levers 46 that extend in the vertical direction, the turning solenoids 47 and the turning solenoids 47 that are arranged in the crocodile facing the extension direction of the respective free ends. The other ends of the return springs 48, one end of which is locked to the opposite sides, are connected to each other. In this separation roller displacing means 900, normally (when the turning solenoid 47 is not operated), the separation roller 10 is at the position shown by the broken line in FIG. 18, that is, the turning roller 9 and the separation roller 1.
0 and 0 are arranged at the same height, and when the manuscript page is turned, the turning solenoid 47 is actuated to separate it to the position shown by the solid line in FIG. The separation roller 10 is displaced so that the height of the roller 10 becomes higher.

Here, the turning solenoid 47 is shown in FIG.
As shown in, the page turning reading unit 1 moves in the page turning direction, and is turned on at the time when the end of the uppermost page of the book document O corresponds to a substantially intermediate position between the turning roller 9 and the separation roller 10. It The operation timing of the flipping solenoid 47 is determined by the size of the book document O set on the document placing surface 100a of the document placing table 100. That is, the turning solenoid 47
Is the book manuscript size from when the page turning reading unit 1 starts the page turning operation until the end of the uppermost page of the book manuscript O corresponds to a substantially intermediate position between the turning roller 9 and the separating roller 10. The required time or the moving distance corresponding to is obtained by counting the number of pulses of the stepping motor, for example, and is turned on when this count value matches the reference value of the book document size input in advance.

As a result, the separation roller 10 is displaced to the position indicated by the solid line in FIG. 18, and as shown in FIG. After being separated from the page and subjected to curvature separation by the separating roller 10, as shown in 1F of FIG. It is accommodated in the page accommodating member 15 while being wound in a cylindrical shape along the inner peripheral surface of the. In this way, when the turning operation of the uppermost page of the book document O attracted to the page turning belt 200 is completed, the turning solenoid 47 is released, and the elastic force of the return spring 48 causes the separation roller 10 to move to the position shown in FIG. 18 is returned to the position shown by the broken line.

As described above, the original surface of the book original O, from which the uppermost original page has been separated, has a circumference faster than the moving speed of the page turning reading unit 1 in the page turning direction, as shown in FIG. At a speed, it is pressed downward by the page pressing brush 49 rotating counterclockwise in FIG. In this way, the page pressing brush 49 presses the original surface, so that the sliding contact of the reading sensor 13 with the original surface during the page turning operation is avoided,
The misalignment of the next original page is prevented. Further, this page pressing brush 49 is rotated clockwise in FIG. 22 at a peripheral speed faster than the moving speed of the page turning reading unit 1 in the page turning direction in FIG. As a result, the pages discharged from the page storage unit 500 are extended and pressed against the document surface of the book document O, so that the page turning operation is performed reliably. Here, the same effect can be obtained by replacing the above-mentioned page pressing brush 49 with a page pressing roller 50 as shown in FIG.

Further, the page pressing brush 49 and the page pressing roller 50 described above do not necessarily need to rotate, and the page pressing brush 49 or the page pressing roller 5 is required.
Even if 0 is rotatably arranged, it is effective. further,
As shown in FIG. 24, the reading sensor 1 is replaced by the page pressing brush 49 and the page pressing roller 50 described above.
A flexible guide member 51 such as mylar is attached to the end portion of 3 by extending the page-turning guide 16 to the crocodile,
As shown in FIG. 25, even when a similar flexible guide member 52 is attached to the back surface of the page-conveying surface of the page-turning guide 16 so that the reading sensor 13 extends to the crocodile and attaches to the page-turning operation. Collision of the reading sensor 13 with the end of the document is avoided, and the page ejected from the page storage unit 500 is extended by the flexible guide member 51 (or 52), so that the page of the document that is turned over is The occurrence of jams is prevented. here,
The flexible guide member 51 (or 52) is provided on the back of the page conveying surface of the page turning guide 16 and the reading sensor 13.
It may be affixed between both unit side plates 5 between and.

By the way, as described above, the separation roller 1
Since the traveling direction of the original pages in the page storage member 15 after being separated by 0 differs depending on the paper quality of the original pages of the book original O, the page storage member 1 is not always required.
There is no guarantee that the direction will be along the inner peripheral surface of 5. Therefore, the page storage member 1 after being separated by the separation roller 10
In the case where the traveling direction of the document page in 5 is not along the inner peripheral surface of the page storage member 15, the flipped document page is jammed in the page storage member 15,
When the document is discharged, the document page is damaged and remains in the page storage member 15, or wrinkles or folds occur.

Therefore, in this embodiment, as shown in FIG.
Page storage guide 53 having an outer diameter smaller than the inner diameter of
Is provided. As a result, as shown in FIG. 26, the uppermost original page separated from the book original O is separated from the page storage member 53 even if the paper quality is slightly hard. By entering between the inner peripheral surface of 15 and the page storage member 1,
The page storage member 1 is bent along the inner peripheral surface of
It is stored smoothly in 5.

Here, the page storage guide 53 is the POM.

The pressure applied to the document surface of the book document O is absorbed and maintained at an appropriate value at all times regardless of the thickness of the book document. Therefore, according to this embodiment, the page turning belt 200
However, since the tension which is substantially constant is always maintained, the reliability of the page turning reading unit 1 during the reciprocating movement is improved. In the page-turning belt 200 of this embodiment, the end of the page-turning reading unit 1 on the turning point side is
Since it is fixed to the belt tension movable roller 87 that can move up and down against the tension force of the tension spring 86, as described above, excessive tension is applied to the page turning belt 200 and the tension spring 86 expands. Therefore, even if the contact position of the page turning belt 200 with respect to the document surface is displaced, the position deviation of the document surface on the home position side of the page turning reading unit 1 can be minimized. It is possible to improve the position accuracy of the operation control of.

The positional deviation of the document surface on the turnaround point side of the page turning reading unit 1 at this time is substantially eliminated by the reading scanning movement of the page turning reading unit 1, so that the document surface in this embodiment is the result.

Further, the positional deviation of the document surface on the turnaround point side of the page-turning reading unit 1 at the time of setting the document acts so as to loosen the end of the page-turning edge of the set book document O. This has the effect of preventing multiple page turning due to.

By the way, this page-turning belt 200
The tension (including the tension force of the tension spring 86) gradually decreases as the upper unit 2 is repeatedly opened and closed and the page turning reading unit 1 is repeatedly moved back and forth.
Therefore, in this type of device, the page turning belt 2
It is necessary to readjust the tension of 00 at a proper time. At the time of this adjustment, it is not so difficult to replace the tension spring 86, and the cost does not become a heavy burden.
On the other hand, only the length of the page turning belt 200 is
Replacing the page-turning belt 200 when the length is longer than the initial length and it is still sufficiently usable, requires a great deal of labor for the replacement work and also a large cost burden. Become.

It is the distance to the department.

Thus, when it is determined that the page reading unit 1 has moved a predetermined amount in the reading scanning direction, it is determined whether the reading sensor 13 has detected the edge of the book original O. Here, as a method of detecting the edge of the book document O by the reading sensor 13, for example, a reading signal of the document surface of the book document,
This is performed by detecting the difference from the read signal on the document placement surface.

Accordingly, when it is determined that the reading sensor 13 has detected the edge of the book document O, the counter counts for t seconds. This count time t
(T = 1 in this embodiment) is the time required to continue the movement of the page turning reading unit 1 in the reading scanning direction by the distance required to satisfy the above conditions, and is the turning point. Is determined by the distance from the position of the reading sensor 13 to the edge of the book document O (25 mm in this embodiment) and the moving speed of the reading sensor 13 in the reading scanning direction (25 mm / sec in this embodiment).

When the count value of the counter reaches this count time t, the drive motor 42 is rotated in the reverse direction,
The return movement of the page turning reading unit 1 toward the home position is started, the control by this subroutine is completed, and the process is returned to the main routine.

As described above, in this embodiment, since the reading operation and the page turning operation of the page turning reading unit 1 can be controlled as a series of movements, the continuous operation is possible and the driving efficiency is improved.
