The configuration and operation unique to this 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 part forming means 300 that separates a part of the page turning belt 200 from the document placing surface 100a and forms the detouring part 200a on the page turning belt 200. It is functioning. Also, the turning roller 9
The separating roller 10 also 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 a page attracting unit 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.

In the detour 200a of the page turning belt 200, the reading unit 4 is attached to the original placing surface 100a.

On the other hand, a page storage member 15 as the page storage means 500 and a page turning guide 16 which are arranged in parallel along the original scanning direction are provided.

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, and do not directly contact the book original O, and normally, the page turning belt 2 is provided.
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 lifting operation 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 performed by a lifting mechanism 800 with an inclination preventing function. The lifting mechanism 800 is composed of a link mechanism as shown in FIGS. 6 to 8. That is, in FIGS. 6 to 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 respective 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, and this guide pin 31
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 performed. By 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 skewing of the page turning reading unit 1 when the page turning reading unit 1 is moved up and down, and the original 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 elevating 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 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 two 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 pieces are laterally laid on the front and rear side plates of the upper unit 2 in parallel with 0a, and both ends thereof are fixed. Further, the unit driving plate 36 is integrated with a timing belt 39 stretched between the guide rods 37 by a fixing plate 38 formed on the outer side 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 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.

The page rake angle θ of the page-turning guide 16 in the page-holding port 500a of the page-holding means 500 enters the page-holding port 500a of the book document O separated from the page-turning belt 200 by the page-separating means 700. 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 entrance 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. This 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 better to be 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 of the page turning guide 16 close to the document placing surface 11a. Therefore, if the page rake angle θ1 of the page turning guide 16 is too small, the page turning 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 end 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 document 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 that 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 direction in which the uppermost page separated by the separation roller 10 enters 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 on the 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.

In the page turning reading unit 1 of this embodiment, as shown in FIG.
By disposing 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,
As a result of the experiment, it was confirmed 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 the page turning is improved. Here, in the present embodiment, the facing plate 44 is made of a metallic plate material, but the facing plate 44 does not necessarily have to be made of a conductive member such as metal, and an insulating member is also used. A similar effect was obtained.

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, is used). By adopting a structure in which the turning support plate 45 having a curved surface of (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 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 coped with by setting the radius R1 of the turning roller 9 to 20 mm or more. However, if the radius R1 of the turning roller 9 is increased in this way, the size of the page turning reading unit 1 becomes large. It causes trouble.

Further, as shown in FIG. 17, the surface of the turning support plate 45 is closer to the separation roller 10 in the direction of the edge, that is, in the direction of entering the page into the page storage port 500a of the page storage means 500. Since the curvature is gradually increased, the original page is turned over against the stiffness 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.

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 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 separating means 700, as shown in FIGS. 18 to 21, the separating roller displacing means 900 may be configured to displace the separating 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 separation 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 extending direction of the respective free ends. The other ends of the return springs 48, one end of which is locked to the opposite side, 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.

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 according 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 separating roller 10 is displaced to the position shown by the solid line in FIG. 18, and as shown in FIG. 21, only the uppermost page of the book original O attracted to the page turning belt 200 is changed to another position. After being separated from the page and curvature-separated by the separating roller 10, as shown in FIG. 1F, the page storage member 500 is guided into the page storage member 15 through the page storage port 500a and along the page turning guide 16. 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, 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 document surface, so that the sliding contact of the reading sensor 13 with the document surface during the page turning operation is avoided,
The misalignment of the next original page is prevented. Further, the 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 surely performed. 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.

FIG. 104 shows the main routine of the drive control unit of the page turning reading unit 1. FIG. 104
In the above, the abnormality detection of the page turning reading unit 1 is performed by periodically executing the turning unit abnormality detection routine incorporated in the main routine.

First, the interrupt routine according to the present invention will be described. From the main control board above,
Commands such as forward, reverse, scan length, and speed,
Alternatively, when the data is transmitted, it is accepted by the serial reception interrupt routine shown in FIG. 105, and the process corresponding to the received data and the flag are set. FIG. 106
Is an encoder interrupt routine, which counts up the encoder interrupt counter, performs speed control, and position control, and resets the turning unit abnormality detection timer. In the timer interrupt routine of FIG. 107, the interrupt is set so as to enter in a time sufficiently shorter than the previous encoder interrupt cycle, and the turning unit abnormality detection timer is incremented.

By the way, as for the operation abnormality of the page turning reading unit 1, when the original page cannot be stored in the page storing means 500 when the original page is stored, and when the original page is discharged, the original page is discharged from the page storing means 500. It is necessary to detect the impossible state. The operation abnormality at the time of turning pages can be detected by the presence / absence of operation of a page storage detection sensor arranged in the page storage means 500 for detecting the presence / absence of storage of document pages. In this embodiment, the page storage state and the page discharge state can be detected by the detection timing of one page detection sensor.

An example of the detection operation according to the present invention will be described with reference to the flowchart of FIG. 108 (turning unit abnormality detection routine). In FIG. 108, first, it is determined whether the motor-on flag is set and whether the page-turning unit abnormality detection timer value is larger than the error-time value, and then the page-turning reading unit 1 is driven. If there is no abnormality, it is determined whether or not the page turning operation is being performed, and in FIG. 106, it is determined that the counted-up encoder interrupt counter value is equal to or greater than the set value 1 and equal to or less than the set value 2. Here, the encoder interrupt counter value is a value indicating the moving position of the page turning reading unit 1 at the time of page turning. With this value, the position where the document page is stored and crosses the page detection sensor is set to a certain width, That is, by judging the set value 1 and the set value 2, it is possible to detect whether or not the original page can be stored at the time of storing the page by determining the set state of the page turning sensor ON flag of FIG. 108 only at the above timing. To do.

At this time, when it is determined that the document page cannot be stored, the drive motor 42 is rotated in the normal direction to move the page-turning reading unit 1 at the present time in the direction opposite to the page-turning direction (document-scanning direction). Move
The page turning abnormality flag 1 is set to display the page storage abnormality, and after the operation is stopped by this flag, the page turning reading unit 1 performs the page turning operation again. Similarly, at the time of ejecting the original page, as shown in FIG. 108, the set state of the page turning off flag is judged within the range of the set value 3 and the set value 4, and if the off flag is not set, the driving is performed. The motor 42 is stopped, the abnormality flag 2 is set, and the page discharge error is displayed.

Here, the values from the set value 1 to the set value 4 are the size of the book original and the page storing means 50.
It is a value set according to the position of the page detection sensor within 0. That is, when the encoder interrupt counter value is in the range of the set value 1 to the set value 2, the page storage detecting operation in the page storing means 500 is performed, and when it is in the range of the set value 3 to the set value 4, the page is stored. The page discharge detection operation from the storage unit 500 is performed. Also,
The width (time) between each set value 1 to set value 2 and each set value 3 to set value 4 is generated by the bending and slippage of the document page in consideration of the bending amount and slippage amount of the document page stored or discharged. It is set so that the error of the leading edge position of the document page does not affect the detection of storage and discharge of the document page.

Next, the processing when a page storage abnormality (page turning error) of a document page in the page storage means 500 occurs will be described with reference to FIG. Figure 108
In, when the page storage abnormality is detected, the drive motor 42 is stopped and the page turning abnormality flag 1 is set. If the page turning abnormality flag 1 is set, the page storage abnormality processing routine shown in FIG. 109 is executed. In FIG. 109, first, the value of the page storage abnormality occurrence counter C is incremented by "1",
If C is less than “3”, then the voltage setting value of the high voltage power supply (high voltage generator 80) for forming the non-uniform electric field pattern on the page turning belt 200 is “ 100 V "is added, and the high-voltage power supply is turned on. At the same time, the drive motor 42 is normally rotated to return the page-turning reading unit 1 to the page-turning operation start position, and the drive motor 42 is stopped.

At this time, the page-turning reading unit 1 is returned to the page-turning operation start position by changing the unit movement amount during the page-turning operation (when the drive motor 42 is rotated in the reverse direction) to the drive shaft of the drive motor 42, or The detection is performed by counting the encoder pulses of an encoder provided on the support shaft of the turning roller 9 and the like, and is performed by driving the drive motor 42 at the time of normal rotation of the drive motor 42 until the same number of counts is performed.

By the series of operations described above, an electric field pattern for attracting and separating the original pages of the book original O is formed on the page turning belt 200. Prior to the formation of the electric field pattern, the high voltage power source is formed. Since the voltage setting value of is set to "200V", the attraction force of the original page due to the electric field turn formed on the page turning belt 200 is stronger than that at the previous page turning operation in which the page turning error occurs. Has become.

Therefore, as described above, after the page turning reading unit 1 returns to the page turning operation starting position, the drive motor 42 is rotated in the reverse direction,
It is possible to improve the reliability of the page turning operation when the page turning operation is performed again. Here, even if the page turning operation is performed again as described above, if the page turning error occurs again, the page turning reading unit 1 is turned over after the voltage of the fountain pressure power supply is further increased. Return to the operation start position and execute the page turning operation again.

At this time, the voltage value of the high-voltage power supply to be raised each time a page turning abnormality occurs is not always the above-mentioned "20".
It is not limited to "0V", and may be appropriately set according to the relationship with the power supply voltage in the standard state, the environment such as temperature and humidity, and the condition such as the quality of the book original. Further, the above-mentioned rising voltage value does not necessarily have to be constant, and may rise like a quadratic curve in accordance with the number of page-turning error occurrences.

As described above, the high-voltage power supply voltage is sequentially increased every time a page-turning error occurs for the same original page, and thus the page-turning belt 20 for the original page
The adsorption force to 0 can be increased. However, when the above-described page turning error occurs a large number of times in succession, the page turning operation may occur due to deformation such as edge folds and curls of the document page edges, or misalignment of the book document. It is often impossible, and it is not preferable for safety to raise the high-voltage power supply voltage too much.

Therefore, as described above, when the page turning abnormality for the same original page occurs a predetermined number of times in succession, the operation of the page turning reading unit 1 is stopped to notify the page turning abnormal state. To configure. In this embodiment, the operation of the page turning reading unit 1 is stopped when the page turning error described above occurs three times in a row (when the value of the page storage abnormality occurrence counter C becomes "3" or more). Then, the abnormal page turning state is notified.

On the other hand, in the above-described embodiment, after the high-voltage power supply voltage is increased and the page-turning operation is normally executed, when the page-turning operation for the next page is performed, the voltage value of the high-voltage power supply is reset to the original value. However, if the page turning error of the previous page occurs due to the condition such as the quality of the book original, the same page turning error is likely to occur during the page turning operation of the next page. Therefore, in such a case, without resetting the voltage value of the high-voltage power supply to the original value, the above-mentioned electric field pattern is formed with the increased voltage value, and the page turning operation for the following pages is performed. Configure to run. In this configuration, when the page turning error for the same original page occurs a predetermined number of times in succession, the operation of the page turning reading unit 1 is not stopped to notify the page turning abnormal state, but the high voltage source voltage value is set. Execute a control to sequentially raise each time a page turning error occurs,
If this voltage value rises more than that, a dangerous value such as K
When it becomes V or more, the operation of the page-turning reading unit 1 is stopped and the abnormal page-turning state is notified.

Further, the stoppage of the page-turning reading unit 1 and the notification operation of the abnormal page-turning state may be performed when the cumulative number of page-turning errors has reached a predetermined number or more. In this case, the predetermined cumulative number of occurrences is set corresponding to the voltage value when the high-voltage power supply voltage is raised over the predetermined number of times.

On the other hand, in order to improve the reliability of the page turning operation when the page turning is reexecuted, the page turning moving speed (unit linear speed) of the page turning reading unit 1 is set every time a page turning error occurs. It may be controlled so as to sequentially decrease at a predetermined rate, for example, a rate of 10%. Also in this case, as in the case of the control described above, the unit linear velocity is sequentially decreased to re-execute the page turning operation, and if the page turning is normally performed, the page turning operation of the next page is performed. The unit linear speed (moving speed setting value) may be reset to the initial value, or the page turning operation may be executed at the unit speed which is continuously reduced even after the next page.

Here, as in the former case, when the speed control of the unit linear velocity at the time of re-page turning is performed for each original page, as described above, the page turning error for the same original page is repeated a predetermined number of times. If the error occurs, the operation of the page-turning reading unit 1 is stopped to notify an abnormal page-turning condition, and like the latter, the unit linear velocity once lowered at the time of re-page-turning When the page turning operation is maintained, the unit linear velocity (moving speed setting value) is sequentially decreased each time a page turning error occurs, and the moving speed setting value is set to a predetermined value, for example, 30 mm / sec
Page turning reading unit 1 when:
Is stopped to notify an abnormal page turning condition.

In addition, the operation of stopping the page turning reading unit 1 and informing the abnormal page turning state is performed by setting the page turning moving speed of the page turning reading unit 1 when the cumulative number of page turning errors occurs for a predetermined number of times or more. It may be set according to the moving speed setting value when the value is lowered.

[0159]

According to the present invention, when the page turning abnormality detecting means detects the page turning abnormal state, the page turning unit is retracted to the page turning start position, and the page turning operation by the page turning unit is performed again. Since it is executed, if a page turning error occurs in a book document, this page turning operation can be re-executed, and reliability and operability are ensured so that the device is not unnecessarily stopped by a simple page turning error. It is possible to provide a page turning device for improved book manuscript.
