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, so that the description here is omitted.

A description will now be given of the configuration and operation of the present embodiment which are different from the MFDS of the prior application and which are unique to the present embodiment.

As shown in FIG. 5, the page turning reading unit 1 is provided with various rollers 6, 7, 8, 9, 10, 11, and 12 between a pair of front and rear unit side plates 5 so as to be rotatable. Supported. Here, the belt supporting rollers 6, 7, and 8 serve as belt bypass portion forming means 300 that forms a bypass portion 200 a on the page turning belt 200 by separating a part of the page turning belt 200 from the document placing surface 100 a. It is functioning. Also, the turning roller 9
The separation roller 10 functions as a page separating unit 700 that separates the document pages adsorbed on the page turning belt by a curvature according to the curvature of the page turning belt 200 at a portion facing the page storing opening 500a of the page storing unit 500. . Further, the charging roller 11 and the counter electrode roller 12 function as a page suction unit 600 that charges the page turning belt 200 with an unequal electric field and causes the page turning belt 200 to suck the pages of the book document O.

The detour section 200a of the page turning belt 200 has a reading section 4 with respect to the original placing face 100a.
00a facing each other, the reading means 40 disposed on the side of the bypass portion 200a in the document reading scanning direction (the direction of the arrow a).
The reading unit 13 and the reading sensor control board 14 are set to 0, and the page storage opening 500a is opened in the page turning direction (the direction of the arrow b) opposite to the document reading scanning direction of the detour unit 200a.
A page storage member 15 as a page storage means 500 and a page turning guide 16 are disposed in parallel along the document reading scanning direction.

Furthermore, ride-up guides 17 and 18 supported between the unit side plates 5 are disposed at the end in the scanning direction and the end in the reading direction of the page turning reading unit 1, respectively. I have. The running guides 17 and 18 are located on the opposite side of the book document O with the page turning belt 200 interposed therebetween, do not directly contact the book document O, and usually have the page turning belt 2.
00, the page turning reading unit 1 moves in the reading scanning direction shown by an arrow a in FIG. 3, and the page turning reading unit 1 moves in the page turning direction shown by an arrow b in FIG. It has a function of smoothing up and down operations of the page turning reading unit 1 with respect to the document surface of the book document O during movement.

The lifting / lowering of the page-turning reading unit 1 at this time is performed by a lifting / lowering mechanism 800 having an inclination preventing function. This elevating mechanism 800 is configured by a link mechanism as shown in FIGS. That is, in FIGS. 6 to 8, one ends of the first link 21 and the second link 22 are rotatably supported at the ends of the studs 19, 20 for fixing the riding guides 17, 18 to the unit side plate 5, respectively. Have been. The other ends of the first and second links 21 and 22 are rotatable by stepped screws 23 and 24 at the respective ends of the third link 25 and the fourth link 26 and both ends of the side link 27. It is pivoted. The other ends of the third link 25 and the fourth link 26 are connected to studs 28 and 29, respectively.
Accordingly, the unit driving side plates 30 are rotatably supported on the respective units. Further, a guide pin 31 is fixed outside the unit side plate 5.
Are vertically movably fitted in a long groove 32a of the unit elevating guide 32 provided inside the unit driving side plate 30.

According to the elevating mechanism 800, when the page turning reading unit 1 reciprocates, the running guides 17 and 18 receive the force from the respective traveling directions due to the thickness of the book document O, and the running is performed. By the upward component force acting on the guides 17 and 18, the page turning reading unit 1 is raised without tilting (FIG. 8). Further, according to the elevating mechanism 800, the guide pins 31 fixed to the outside of the unit side plate 5 are moved up and down along the long grooves 32a of the unit elevating guide 32 disposed inside the unit drive side plate 30. It is possible to prevent skew of the page turning reading unit 1 when the page turning reading unit 1 moves up and down, and the document scanning speed of the reading sensor 13 does not change due to the vertical movement of the page turning reading unit 1. Stable image scanning is realized.

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

9 and 10, a unit upper and lower rod 34 is fixed to two upper and lower rod fixing plates 33 formed on the unit driving side plate 30. Two 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 lifting mechanism configured as described above, the upper and lower unit upper and lower guide plates 35 slide along the upper and lower unit rods 34 to move the page turning reading unit 1 up and down. Even if a rotational moment acts upon the lifting and lowering of the unit 1, the page turning reading unit 1 is smoothly raised and lowered 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 reciprocatingly driving the unit driving side plate 30 described above. As shown in FIGS. 11 to 13, the unit driving plate 30 has three guide members 36 formed on the outside thereof fitted into guide rods 37, thereby allowing the unit driving plate 30 to move in the left-right direction in FIGS. 12 and 13. , Are slidably supported. The guide rod 37 is attached to the original placing surface 10.
In parallel with the upper unit 2, two units are respectively laid on the front and rear side plates of the upper unit 2, and both ends are fixed. The unit driving plate 36 is integrated with a timing belt 39 stretched between the guide rods 37 by a fixing plate 38 formed outside the unit driving plate 36. As shown in FIGS. 12 and 13, the timing belt 39 is rotatably stretched by a driving pulley 40 and a driven pulley 41 pivotally supported on front and rear side plates of the upper unit 2. Each drive pulley 40 is driven to rotate via a driven drive shaft 43, so that the drive pulley 40 is driven to reciprocate. As described above, the timing belt 39 is driven to reciprocate at a predetermined timing, so that the page-turning reading unit 1 operates as shown in FIG.
As shown in FIG.
Is reciprocated along the original 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 determined by entering the book original O separated from the page turning belt 200 by the page separating means 700 into the page storing opening 500a. It is necessary to make the angle smaller than the angle α to eliminate the separation error of the document. 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 opening 500a of the page storing means 500 is used. The rake angle θ1 is the approach angle α of the book document O separated from the page turning belt 200 by the page separating means 700 into the page storage opening 500a.
It is configured to be smaller than In this case, the page rake angle θ1 of the page turning guide 16 is preferably not more than 60 degrees, and preferably not more than 10 degrees. Page rake angle θ of this page turning guide 16
1 is different depending on the turning margin of the book original O with respect to the material of the page. When the original page is soft, the approach angle α into the page storage opening 500a becomes relatively large, so that the separation is possible even at an angle of about 60 degrees. When the original page is hard, the entry angle α into the page storage opening 500a becomes relatively small, so that it is better to be as small as 10 degrees or less.

However, as shown in FIG. 14, when the turning roller 9 and the separation roller 10 are arranged at the same height, this page turning guide 1
In order to reduce the page rake angle θ1 of No. 6, it is necessary to bring the lower end of the page-turning guide 16 close to the document placing surface 100a. If the end of the book document O rises for some reason when the reading unit 1 moves in the page turning direction,
There is a possibility that the lower end of the page turning guide 16 may contact the end of the book document O. Therefore, in the page turning reading unit 1 of this embodiment, as shown in FIG. 5 and FIG.
0 is increased so as to increase the separation position of the book document O separated from the page turning belt 200 and to increase the substantial entry angle α1 of the document page into the page storage opening 500a. enables separation sufficiently lower end portion of the page turning guide 16 from the document placing surface 100a, and is configured to pages rake angle θ2 of the page turning guide 16 can be reduced to ten minutes.

As a result, the top page of the book document O, which is attracted to the page turning belt 200 and separated by the curvature by the separation roller 10, is passed through the page storage opening 500a as shown in FIG. Is stored in the page storage member 15 while being wound into a cylindrical shape along the inner peripheral surface of the page storage member 15. And FIG. 4, FIG.
As shown in FIG. 15, the page turning belt is
Page separation direction near the separation section 700 of the manuscript page
To the storage section on the next page.
Approach is blocked.

Here, the entry direction of the top page separated by the separation roller 10 into the page storage port 500a is as follows.
As described above, since the approach angle α1 to the page storage opening 500a differs depending on the paper quality of the document page to be separated, it does not necessarily follow the direction along 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 on the outer peripheral portion facing the page turning guide 16, and the entry direction of the top page separated by the separation roller 10 into the page storage opening 500a regardless of the paper quality of the document page to be separated. Is forcibly deflected in the direction along the page turning guide 16.

In the page turning reading unit 1 of this embodiment, as shown in FIG.
By disposing the opposing plate 44 in close contact with the back side of the page turning belt 200 between the
Is increased document page adsorption force non-uniform electric field pattern formed on a page turn belt 200, it may improve the reliability of the page when chestnut confirmed the results of experiments. here,
In this embodiment, the opposing plate 44 is made of a metal plate. However, the opposing plate 44 does not necessarily need to be made of a conductive member such as a metal, and the same effect can be obtained with an insulating member. was gotten.

In addition, as shown in FIG. 16, the page separating means 700 has a diameter R2 which is sufficiently larger than the radius R1 of the turning roller 9 (in this embodiment, in place of the above-mentioned turning roller 9). With the structure in which the turning support plate 45 having a curved surface (R2 = 75 mm) is provided, the reliability of turning the page is further improved. Here, the surface curvature ρ of the turning support plate 45 is ρ = 1 / R2 =
1/20 or less, that is, the turning support plate 45 has a diameter R2 of 20 mm or more, preferably 60 mm or more. Such a page separating unit 700 can cope with the case where the radius R1 of the turning roller 9 is set to 20 mm or more. However, when the radius R1 of the turning roller 9 is increased, the size of the page turning reading unit 1 is increased. Failure will occur.

As shown in FIG. 17, the turning support plate 45 has its surface closer to the side of the separation roller 10, that is, in the direction of entering the page into the page storing opening 500 a of the page storing means 500. By constructing the curvature so as to gradually increase, the original page is turned over against the stiffness of the original page.
Since the force to bend the fold gradually increases with respect to the original page, the ability of the original page to follow the page turning belt 200 is increased, and the reliability of page turning can be further improved. . FIG. 17 of the present embodiment
The turning support plate 45 shown in FIG.
Are the diameters R3, R4, R5 from the contact point G1 which first comes into contact with the book document to the separation point G2 where the suction-separated document pages are separated from the page turning belt 200 by the curvature separation.
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 such that its surface curvature changes continuously.

In the examples shown in FIGS. 15 to 17, the page separation means 700 in which the separation roller 10 is fixedly arranged in advance so that the height of the separation roller 10 is higher than the height of the turning roller 9 is shown. However, as shown in FIGS. 18 to 21, the page separating unit 700 may be configured so that the separating roller 10 is displaced at a predetermined timing by the separating roller displacing unit 900. As shown in FIG. 19, the separation roller displacing means 900 in this embodiment includes a pair of the turning lever 46, the turning solenoid 47, and the return spring 48. As shown in FIG. 19, each of the turning levers 46 is formed in an L-shape, and each corner is rotatably supported at both ends of a support shaft of the turning roller 9. Separating rollers 10 are rotatably supported at the free ends of these turning levers 46 extending in the horizontal direction. Furthermore, at the base ends of these turning levers 46 extending in the vertical direction, each of the turning solenoids 47 and each of the turning solenoids 47 that are arranged on the bridge facing the extending direction of each free end is provided. The other end of each return spring 48 whose one end is locked to the opposite side is connected to each other. Normally (when the turning solenoid 47 is not operated), the separating roller displacing means 900 moves the separating roller 10 to the position shown by the broken line in FIG.
0 is positioned at the same height, and the turning solenoid 47 is activated during the turning operation of the original page, so that the turning solenoid 47 is separated from the position shown by the solid line in FIG. The separation roller 10 is displaced so that the height of the roller 10 increases.

Here, the turning solenoid 47 is shown in FIG.
As shown in FIG. 5, the page turning reading unit 1 moves in the page turning direction, and is turned on 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. You. The operation timing of the turning 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 size of the book document from when the page turning reading unit 1 starts the page turning operation until the end of the topmost page of the book document O corresponds to a substantially intermediate position between the turning roller 9 and the separation roller 10. Is determined by counting the number of pulses of the stepping motor, for example, and is turned on when this count value matches the previously input reference value of the book document size.

As a result, the separation roller 10 is displaced to the position shown by the solid line in FIG. 18, and as shown in FIG. 21, only the topmost page of the book document O adsorbed on the page turning belt 200 is moved to another position. After being separated from the page and separated by the curvature by the separation roller 10, as shown in FIG. 4F, the sheet is guided into the page storage member 15 along the page turning guide 16 through the page storage opening 500a. 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. In this manner, when the turning operation of the uppermost page of the book document O sucked to the page turning belt 200 is completed, the turning solenoid 47 is released, and the separation roller 10 is moved by the elasticity of the return spring 48 as shown in FIG. It is returned to the position indicated by the broken line in FIG.

As described above, the document surface of the book document O from which the uppermost document page has been separated is, as shown in FIG. At the speed, it is pressed downward by the page pressing brush 49 rotating in the counterclockwise direction in FIG. As described above, when the page pressing brush 49 presses the document surface, the sliding contact of the reading sensor 13 with the document surface during the page turning operation is avoided,
The displacement of the next original page is prevented. In addition, the page pressing brush 49 is rotated clockwise in FIG. 22 at a peripheral speed higher than the moving speed of the page turning reading unit 1 in the page turning direction in FIG. In this way, it is possible to extend the pages ejected from the page storage unit 500 and press them onto the original surface of the book original O, so that the page turning operation can be reliably performed. Here, the same effect can be obtained by replacing the above-described page pressing brush 49 with a page pressing roller 50 as shown in FIG.

The page pressing brush 49 and the page pressing roller 50 do not necessarily need to be rotated.
There is also an effect simply by arranging 0 freely. further,
As shown in FIG. 24, the reading sensor 1 is replaced with the page pressing brush 49 and the page pressing roller 50 described above.
A flexible guide member 51 such as a mylar is attached to the end of the third unit 3 such that the page-turning guide 16 is stretched aside,
As shown in FIG. 25, even when a similar flexible guide member 52 is attached to the back of the page transport surface of the page turning guide 16 by extending the reading sensor 13 to the side, the reading sensor 13 can be used during the page turning operation. Collision of the reading sensor 13 with the end of the document is avoided, and the page discharged from the page storage means 500 is extended by the flexible guide member 51 (or 52). The occurrence of jam is prevented. here,
The flexible guide member 51 (or 52) is provided between the back of the page transport surface of the page turning guide 16 and the reading sensor 13.
May be attached between both unit side plates 5.

By the way, as described above, the separation roller 1
Since the traveling direction of the document pages in the page storage member 15 after being separated by 0 differs depending on the paper quality of the document pages of the book document O, the page storage member 1 is not necessarily required.
There is no guarantee that the direction will be along the inner peripheral surface of No. 5. For this reason, the page storage member 1 after being separated by the separation roller 10
When the traveling direction of the document page in the document 5 does not coincide with the direction along the inner peripheral surface of the page storage member 15, the turned document page jams in the page storage member 15,
At the time of discharging, the original page is broken and remains in the page storage member 15, or a problem such as wrinkling or folding occurs.

Therefore, in this embodiment, as shown in FIG.
Page storage guide 53 having an outer diameter smaller than the inner diameter of
Is arranged. As a result, the outermost surface of the page storage guide 53 and the page storage member 53 are shown in FIG. 15 and the inner surface of the page storage member 15,
5 is bent along the inner peripheral surface of the page storage member 1.
5 is stored smoothly.

Here, the page storage guide 53 is a POM
(Polyacetal), or a Teflon-coated cylindrical member having a smooth surface, or a cylindrical member made of styrene foam, polyurethane foam, or a metallic hollow cylinder, is fixed in the page storage member 15. Or it is configured to be pivotally supported. Further, as shown in FIG. 27, the page storage guide 53 is configured such that a columnar member formed of an extremely lightweight material such as styrene foam or polyurethane foam is fixed or pivotally supported in the page storage member 15. The same effect can be obtained even if the structure is simply inserted. Further, the inner peripheral surface of the page storage member 15 is formed of a low friction member such as Teflon (fluororesin),
The uppermost document page separated from the book document O is smoothly inserted into the page storage member 15.

On the other hand, the reading sensor 13 provided in the page turning reading unit 1 has a sensor swing mechanism,
And, by the sensor elevating mechanism, slightly swing, and
It is configured to be raised and lowered. FIGS. 28 to 3 show the configurations of the sensor swing mechanism and the sensor elevating mechanism.

Since the members B disposed on the outer peripheral surface side of the page turning belt 200 can be separated from each other, these members A and B are assembled independently beforehand, and then the member A is attached to the member B with the page turning belt 200 interposed therebetween. The page turning reading unit 1 and the page turning belt 200 can be assembled by a simple operation of assembling.

In the MFDS of this embodiment, as shown in FIG. 2, a cleaning roller 82 is provided above the original placing surface 100a at a position (1H in FIG. 4) on the home position side of the original placing table 100. To make a part of the surrounding surface protrude,
It is arranged rotatably. This cleaning roller 8
Reference numeral 2 denotes a reading surface of the reading sensor 13 (the platen is on the lower surface of the lath) when the page turning reading unit 1 is at its home position as shown in FIG.
It is arranged at a position where it abuts. The cleaning roller 82 is rotationally driven by a drive device (not shown) (the direction of rotation is not particularly limited), and every time the page turning reading unit 1 returns to its home position, the reading surface of the reading sensor 13 (platen (The lower surface of the lath) and rotationally cleans the reading surface of the reading sensor 13.

Here, as a means for cleaning the reading surface of the reading sensor 13, a cleaning member made of felt or the like is fixedly arranged on the original placing surface 100a. The reading surface of the reading sensor 13 may be configured to be rubbed and cleaned. The position of the cleaning means is determined by the page turning reading unit 1.
It is not necessary to limit to the home position position, and any position may be used as long as the position is within the reading scanning movement range outside the mounting area of the book document of the maximum size that can be mounted.

As shown in FIG. 1, one end of the MFDS page turning belt 200 has a belt tension fixing roller 83 (home position side).
After being deflected by the belt support roller 84 (home position side) in the direction along the document placing surface 100a to form the detour portion 200a in the page turning reading unit 1, it is further fixed. It is bent upward by the belt support roller 85 (turning point side),
The other belt end is fixed to the belt tension movable roller 87 attached to the lower end of the tension spring 86, and the belt tension movable roller 87 is pulled upward by the contraction force of the tension spring 86, A predetermined tension is applied to the page turning belt 200.

As shown in FIG. 89, when a relatively thick book document O is set, when the operator closes the upper unit 2, a pressure Fa is applied to the upper unit 2 in the closing direction. With this, the page turning belt 2
A reaction force Fb in a direction to open the upper unit 2 acts on a contact portion of the book document O with the book document O.

Therefore, if both ends of the page turning belt 200 are fixed so as to keep the stationary state, the reaction force Fb directly becomes the pressing force of the original surface of the book original O, and the page turning operation is performed. Excessive tension is applied to the belt 200, and the load at the time of reciprocating movement of the page turning reading unit 1 is significantly increased.

On the other hand, in the page turning belt 200 of this embodiment, one end of the
Belt movable roller 8 that can move up and down against the contraction force of
7, as described above, even if excessive tension is applied to the page turning belt 200, the excessive tension applied to the page turning belt 200 is increased by the extension of the tension spring 86. It is absorbed, and the pressing force against the original surface of the book original O is always kept at an appropriate value regardless of the thickness of the book original. Therefore, according to this embodiment, the page turning belt 200 is used.
However, since a substantially constant tension is always maintained, the reliability of the reversing movement of the page turning reading unit 1 is improved. In the page turning belt 200 of the present 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 which can move up and down against the contraction 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 a position shift occurs in the contact position of the page turning belt 200 with respect to the document surface, the position shift of the document surface on the home position side of the page turning reading unit 1 can be minimized. The position accuracy of the operation control can be improved.

Note that the positional deviation of the document surface on the turning point side of the page turning reading unit 1 at this time is almost eliminated by the reading scanning movement of the page turning reading unit 1, so that the document surface in this embodiment is Almost no displacement occurs. Also, the positional deviation of the document surface on the turning 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 of the set book document O. Has the effect of preventing multiple pages from being turned.

By the way, this page turning belt 200
(Including the contracting force of the tension spring 86) gradually decreases due to repeated opening and closing of the upper unit 2 and repeated reciprocation of the page turning reading unit 1.
Therefore, in this type of apparatus, the page turning belt 2 is used.
It is necessary to re-adjust the tension of 00 as needed. In this adjustment, replacing the extension spring 86 is not so difficult and does not impose a large burden on cost.
On the other hand, only the length of the page turning belt 200 is
Replacing the page turning belt 200 when it has grown longer than the initial length and it can still be used sufficiently requires a great deal of labor for the replacement work and a great burden in terms of cost. Become.

Therefore, in this embodiment, the belt tension fixing roller 83 to which the belt end of the page turning belt 200 on the home position side is fixed, as shown in FIG.
It is disposed on the upper unit 2 via the one-way clutch 88. According to this embodiment, as described above, if only the length of the page turning belt 200 is longer than the initial length and it can still be used sufficiently,
It is easy to rotate the belt tension fixing roller 83 in a predetermined direction (movable direction of the one-way clutch 88) and wind the stretched and slack portion of the page turning belt 200 around the belt tension fixing roller 83. With a simple operation, the tension of the page turning belt 200 can be adjusted as needed. Further, according to this embodiment, even when the contraction force of the tension spring 86 is slightly reduced, the belt tension fixing roller 83 is rotated in a predetermined direction to rotate around the belt tension fixing roller 83. , Page turning belt 20
By winding 0, the contraction force can be restored without replacing the tension spring 86.

Further, in this embodiment, the valleys of the binding portions of the book document O set to be spread and set by the apexes (approximately the center in the width direction of the center groove 100b) on the upper surface of the positioning plate 92 on which the book document is placed. That is, since the center portion of the book document O in the spread state is supported, the center position of the document surface of the book document O is always constant, and the positional accuracy of the operation control of the page turning reading unit 1 is improved. .

The embodiment shown in FIG.
The book document positioning member disposed in the area b is composed of a binder unit 94, and is suitable for supporting a relatively thin book document and a document in which a plurality of sheets are stapled or bound with a binding string. It has a structure. In other words, the binder unit 94 is a long channel member 95 that fits in the center groove 100b.

Here, each of the book document positioning members 89 described above is configured to be detachable from the center groove 100b at the center of the document mounting surface 100a, and the type of book document to be set is set. In addition, the most suitable positioning member can be selected and used according to the page position to be opened and the like.

In the following embodiment, the setting position of the book document binding portion in the center groove 100b according to the size of the book document is set to the reference position of the document placing surface 100a (the position on the near side of the apparatus body). 5 is an example of a book document positioning unit configured to be aligned. As shown in FIGS. 99 to 101, the book document positioning means is such that the document set guide 101 is slidably fitted in a guide groove 100c formed along the longitudinal direction of the bottom of the center groove 100b. It is configured. According to the book document positioning means, as shown in FIG.
After the binding portion of the book document O is fitted into the reference position b (a position on the front side of the apparatus main body), the document set guide 101
Is moved until it hits this book document, thereby positioning the book document O. Therefore, in this embodiment, it is possible to prevent the book original from being displaced during the operation of the apparatus.

By the way, as shown in FIG. 3, the page turning reading unit 1 according to the present embodiment first moves the original of the book original O by the reading sensor 13 while moving from the home position toward the turning point. The surface is read and then, as shown in FIG.
During the return movement from the turning point toward the home position, the turning operation of the read original page is performed. Further, as shown in FIG. 5, in the page turning reading unit 1 according to the present embodiment, the page storing means 500 for turning the page turns the home position of the page turning reading unit 1, that is, in the reading scanning direction. The upstream of the reading means 400 is arranged in parallel with the alligator. Therefore, in this embodiment, in order to reliably turn over the document pages of the book document O by the page turning belt 200, the entire surface of the document surface of the book document O set on the document mounting table 100 is turned over by the page turning belt 200.

It is necessary to set the turning point of the page turning reading unit 1 so that 00 is located on the downstream side in the reading scanning direction from the end of the book document O on the turning point side.

Therefore, in this embodiment, as shown in FIG. 102, the page turning reading unit 1 moves in the reading scanning direction, and the reading sensor 13 detects the end of the book document O on the turning point side (FIG. 102). After reaching the point P, the page turning reading unit 1 is further moved in the reading scanning direction, and the turning roller 9 passes through the point P of the book document O to a predetermined distance (the above condition). At a position which is excessively far enough to satisfy the condition (1), the movement of the page turning reading unit 1 in the reading scanning direction is stopped, and this position is used as a turning point to move the page turning reading unit 1 to its home position. It is configured to perform a turning operation of the original page after the reading by returning to the original page.

FIG. 103 is a flowchart for controlling the operation of the page turning reading unit 1 of this embodiment.
Shown in In FIG. 103, when the page turning reading unit 1 is operated and the subroutine of the drive control means (not shown) is started, first, the page reading unit 1 is moved by a predetermined amount in the reading scanning direction. Is determined. Here, the predetermined amount is
A distance obtained by subtracting a distance (50 mm in the present embodiment) for providing a margin for a document edge detection operation to be described later from the book spread size of the book document input in advance, or a document center from the home position of the page turning reading unit 1. It is the distance to the part.

Thus, when it is determined that the page reading unit 1 has moved by a predetermined amount in the reading scanning direction, it is determined whether the reading sensor 13 has detected the edge of the book document 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 O,
The detection is performed by detecting a difference from a read signal of the document placing surface.

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 the present embodiment) is a time required for continuing the movement of the page turning reading unit 1 in the reading scanning direction by a distance necessary to satisfy the above condition, and is a 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, control by this subroutine is completed, and the process returns 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 can be performed, and the driving efficiency is improved.
