  Further, when the page presser shaft 17 is moved to the uppermost position, a stop portion (not shown) hits and the drive current value of the page presser shaft vertical movement motor 49 increases rapidly. It is determined that it has moved to the uppermost position, and the page pressing shaft vertical movement motor 49 is stopped. Further, when the page presser shaft 17 is moved to the rearmost side, a stop portion (not shown) hits and the drive current value of the page presser shaft back-and-forth moving motor 50 increases rapidly. Is determined to have moved to the rearmost side, and the page pressing shaft longitudinal movement motor 50 is stopped.

  Subsequently, the CPU 71 drives the page turning shaft left / right movement motor 18, the page separation shaft left / right movement motor 25, and the page pressing shaft left / right movement motor 32 via the motor drive circuit 63, thereby turning the page turning shaft 15 and the page separation shaft 16. The page presser shaft 17 is moved in the right direction of the frame 2.

  When the CPU 71 detects the reflection marks 21, 28, and 37 provided on the timing belts 11, 12, and 13 via the origin position detection sensors 22, 29, and 38, The page turning shaft left / right moving motor 18, the page separating shaft left / right moving motor 25, and the page pressing shaft left / right moving motor 32 corresponding to 28 and 37 are stopped. That is, the CPU 71 moves the page turning shaft 15, the page separation shaft 16, and the page pressing shaft 17 to the origin position.

  Thereafter, the CPU 71 reads out the predetermined number of drive pulses of each of the left and right moving motors 18, 25, 32 corresponding to the book size, paper quality, and the like input via the operation unit 66 from the ROM 72. Then, the CPU 71 drives each of the left and right moving motors 18, 25, 32 again by the predetermined number of driving pulses via the motor driving circuit 63, and conveys each of the timing belts 11, 12, 13 in the left direction, The page turning shaft 15, the page separation shaft 16, and the page pressing shaft 17 are moved from the origin position to the upper side of the page 3A to be turned of the book 3 (see FIG. 5) (see FIG. 1).

  That is, the CPU 71 moves the page separation shaft 16 upward near the outer edge in the direction orthogonal to the binding 3B (see FIG. 5) of the page 3A to be turned of the book 3. Further, the CPU 71 moves the page presser shaft 17 upward near the binding 3B of the page 3A to be turned. Further, the CPU 71 moves the page turning shaft 15 to a position slightly closer to the page pressing shaft 17 side than an intermediate position between the page separation shaft 16 and the page pressing shaft 17 (see FIG. 1). As will be described later, when the page separation shaft 16 moves to the page pressing shaft 17 side after contacting the page 3A to be turned, the page turning shaft 15 is moved between the page separation shaft 16 and the page pressing shaft 17. It is located approximately in the middle (see FIG. 7).

  Further, the CPU 71 drives the image scanner left / right moving motor 52 via the motor driving circuit 63 to move the image scanner 6 in the right direction of the frame 2. When the CPU 71 detects the reflection mark 55 provided on the scanner timing belt 51 via the origin position detection sensor 56, the CPU 71 stops the image scanner left-right movement motor 52. That is, the CPU 71 moves the image scanner 6 to the origin position.

  Thereafter, the CPU 71 reads from the ROM 72 a predetermined number of drive pulses of the image scanner left / right moving motor 52 that moves the image scanner 6 to the outside from the left end edge of the mounting table 4. Then, the CPU 71 drives the image scanner left / right moving motor 52 by a predetermined number of drive pulses via the motor drive circuit 63, conveys the scanner timing belt 51 in the left direction, and moves the image scanner 6 to the left edge of the mounting table 4. It moves to the outside from the part (refer FIG. 1).

  Subsequently, in S12, as shown in FIGS. 5 and 6, the CPU 71 rotationally drives the page separation shaft vertical movement motor 46 to move the page separation shaft 16 downward, so that the page 3A to be turned in the book 3 is displayed. Press. When the drive current value of the page separation shaft vertical movement motor 46 increases rapidly, the CPU 71 determines that the page separation shaft 16 is pressed against the page 3A to be turned, and the page separation shaft vertical movement motor. 46 is stopped.

  Further, the CPU 71 counts the number of pulses for driving the page separation shaft vertical movement motor 46, detects the height of the page 3 </ b> A to be turned from the mounting table 4 and stores it in the RAM 73. When the page separation shaft vertical movement motor 46 is driven by one pulse, the vertical movement amount (for example, about 0.1 mm) by which the page separation shaft 16 moves is stored in the ROM 72 in advance. Further, the distance from the highest page separation shaft 16 to the upper surface of the mounting table 4 is stored in the ROM 72 in advance.

  Further, the CPU 71 rotationally drives the page pressing shaft vertical movement motor 49 to move the page pressing shaft 17 downward and presses it against the page 3A to be turned of the book 3. When the drive current value of the page pressing shaft vertical movement motor 49 increases rapidly, the CPU 71 determines that the page pressing shaft 17 is pressed against the page 3A to be turned, and the page pressing shaft vertical movement motor. 49 is stopped.

  Thereafter, in S <b> 13, the CPU 71 reads from the ROM 72 the predetermined number of drive pulses that rotationally drive the page separation shaft left / right movement motor 25 to move the page separation shaft 16 leftward. Then, as shown in FIGS. 7 and 8, the CPU 71 rotates and drives the page separation shaft left / right movement motor 25 by a predetermined number of drive pulses to move the page separation shaft 16 to the left by a predetermined distance. Thus, a bulging portion 81 is formed between the page separation shaft 16 and the holding shaft 17, in which the page 3 </ b> A to be turned of the book 3 is bent upward.

  Subsequently, in S14, the CPU 71 reads the height of the page 3A to be turned from the placement table 4 stored in the RAM 73 in S12, and has a predetermined height higher than the height of the page 3A to be turned from the placement table 4. (For example, the height is about 5 mm.) The number of drive pulses for lowering the page turning shaft 15 to a high position is read from the ROM 72. The number of drive pulses for lowering the page turning shaft 15 from the highest state to each height from the upper surface of the mounting table 4 is stored in advance in the ROM 72 for every height of about 1 mm.

  Then, as shown in FIG. 10, the CPU 71 rotates the page turning shaft vertical movement motor 42 by the number of drive pulses read from the ROM 72 to lower the page turning shaft 15, and the rear end of the page turning shaft 15. The part is opposed to the bulging part 81. Thereafter, as shown in FIG. 9, the CPU 71 rotationally drives the page turning shaft back-and-forth movement motor 43 to move the page turning shaft 15 to the rearmost side and enter the bulging portion 81. That is, the page turning shaft 15 enters the lower side of the page 3A to be turned.

  Further, when the page turning shaft 15 is moved to the rearmost side (the uppermost side in FIG. 9), the rear end portion is positioned slightly rearward of the center portion of the mounting table 4 in the front-rear direction. Configured to reach. Further, when the page turning shaft 15 is moved to the rearmost side, a stop portion (not shown) hits and the drive current value of the page turning shaft back-and-forth movement motor 43 increases rapidly. Is determined to have moved to the rearmost side, and the page turning shaft longitudinal movement motor 43 is stopped.

  Then, as shown in FIGS. 11 and 12, the CPU 71 rotates the page separation shaft vertical movement motor 46 through the motor drive circuit 63 to move the page separation shaft 16 to the uppermost position. Further, the CPU 71 rotates the page pressing shaft vertical movement motor 49 via the motor driving circuit 63 to move the page pressing shaft 17 to the uppermost side.

  Thereafter, the CPU 71 rotationally drives the page presser shaft back-and-forth movement motor 50 to move the page presser shaft 17 to the foremost side so that the rear end portion of the page presser shaft 17 does not interfere with the turning shaft support portion 41 (for example, , The position between the separation timing belt 12 and the pressing timing belt 13). When the page presser shaft 17 is moved to the foremost side, a stop portion (not shown) hits and the drive current value of the page presser shaft back-and-forth moving motor 50 increases abruptly. It determines with having moved to the most front side, and stops the page pressing shaft back-and-forth movement motor 50.

  Subsequently, the CPU 71 sets the number of drive pulses for moving the page turning shaft 15 from the position where the page turning shaft 15 enters the bulging part 81 to the page turning end position corresponding to the size of the book 3 input via the operation unit 66. It is read from the ROM 72 and stored in the RAM 73 as “movement end pulse number”. The number of drive pulses to be moved from the position entering the bulging portion 81 to the page turning end position is stored in advance in the ROM 72 corresponding to each size of the book 3.

  In S15, as shown in FIGS. 13 and 14, the CPU 71 drives the page turning shaft left / right moving motor 18 via the motor drive circuit 63 to move the page turning shaft 15 to the binding 3B of the book 3. And are moved in the direction of the binding stitch 3B that is orthogonal to each other. At the same time, the CPU 71 counts the number of drive pulses of the page turning shaft left / right movement motor 18 and stores it in the RAM 73 as a “movement count value”.

  Subsequently, in S <b> 16, the CPU 71 executes a determination process for determining whether or not the page turning shaft 15 hits the binding 3 </ b> B of the book 3 and is clogged. Specifically, as shown in FIGS. 15 and 16, when the page turning shaft 15 hits the binding 3B of the book 3 and the movement of the page turning shaft 15 is inhibited, the page turning shaft left and right moving motor 18 The drive current value increases rapidly. For this reason, the CPU 71 determines that the page turning shaft 15 hits the binding 3B of the book 3 and is clogged when the drive current value of the page turning shaft left / right movement motor 18 increases rapidly.

When it is determined that the drive current value of the page turning shaft left / right moving motor 18 increases rapidly, the page turning shaft 15 hits the binding 3B of the book 3, and the movement of the page turning shaft 15 is inhibited ( (S16: YES), CPU71 transfers to the process of S17.
In S17, as shown in FIGS. 17 and 18, the CPU 71 first stops the page turning shaft left / right movement motor 18, and temporarily stops the movement of the page turning shaft 15 toward the binding line 3B.

  Thereafter, the CPU 71 moves the page turning shaft 15 upward by a predetermined height in accordance with the paper quality (for example, thick (hard), normal, thin (soft), etc.) of the book 3 input via the operation unit 66. The number of drive pulses of the page turning shaft vertical movement motor 42 to be moved to is read from the ROM 72. The number of drive pulses of the page turning shaft vertical movement motor 42 that moves the page turning shaft 15 upward by a predetermined height corresponding to the paper quality of the book 3 is stored in the ROM 72 in advance.

  For example, when the paper quality of the book 3 is thick (hard), the CPU 71 reads from the ROM 72 the number of drive pulses of the page turning shaft vertical movement motor 42 that moves the page turning shaft 15 upward by about 10 mm. When the paper quality of the book 3 is normal, the CPU 71 reads from the ROM 72 the number of drive pulses of the page turning shaft vertical movement motor 42 that moves the page turning shaft 15 upward by about 5 mm. Further, when the paper quality of the book 3 is thin (soft), the CPU 71 reads out the number of drive pulses of the page turning shaft vertical movement motor 42 that moves the page turning shaft 15 upward by about 3 mm from the ROM 72.

Then, the CPU 71 rotates and drives the page turning shaft vertical movement motor 42 by the number of drive pulses read from the ROM 72 to move the page turning shaft 15 upward by a predetermined height corresponding to the paper quality, and then again from S15. Execute the process.
That is, as shown in FIGS. 19 and 20, the CPU 71 drives the page turning shaft left / right moving motor 18 again via the motor drive circuit 63 so that the page turning shaft 15 is orthogonal to the binding 3B of the book 3. To move toward the binding 3B side. At the same time, the CPU 71 continuously counts the number of drive pulses of the page turning shaft left / right movement motor 18 and stores it in the RAM 73 as a “movement count value”.

  The CPU 71 drives the page turning shaft left / right moving motor 18 by a predetermined number of drive pulses in accordance with the upward movement of the page turning shaft 15 to move the page turning shaft 15 toward the front side of the binding 3B (see FIG. 18 is a rightward direction), and after the predetermined distance is moved, the processing after S15 may be executed again. Further, the CPU 71 drives the page turning shaft left / right moving motor 18 by a predetermined number of drive pulses in accordance with the upward movement of the page turning shaft 15 to move the page turning shaft 15 toward the binding 3B side (in FIG. 18). , In the left direction)), the process after S15 may be executed again.

  On the other hand, if it is determined in S16 that the page turning shaft 15 does not hit the binding 3B of the book 3 and the movement of the page turning shaft 15 is not hindered, that is, the page turning shaft left / right moving motor 18 is driven. When the current value does not increase rapidly (S16: NO), the CPU 71 proceeds to the process of S18. In S18, the CPU 71 executes a determination process for determining whether or not the page turning shaft 15 has moved to the page turning end position. Specifically, the CPU 71 reads out the “movement end pulse number” and the “movement count value” from the RAM 73 and determines whether or not the “movement count value” is equal to or greater than the “movement end pulse number”. Execute.

When it is determined that the page turning shaft 15 has not moved to the page turning end position, that is, when the “movement count value” is less than the “number of movement end pulses” (S18: NO), the CPU 71 again , S15 and subsequent processes are executed.
On the other hand, as shown in FIGS. 21 and 22, when it is determined that the page turning shaft 15 has moved to the page turning end position, that is, when the “movement count value” is equal to or greater than the “number of movement end pulses”. (S18: YES), the CPU 71 determines that the page turning is finished, and stops the page turning shaft left / right moving motor 18 via the motor drive circuit 63.

  Thereafter, the CPU 71 drives the page turning shaft left / right movement motor 18, the page separation shaft left / right movement motor 25, and the page pressing shaft left / right movement motor 32 via the motor drive circuit 63, respectively, and the page turning shaft 15, page separation shaft 16. The page pressing shaft 17 is moved in the right direction of the frame 2 until the page pressing shaft 17 is located outside the right end edge of the mounting table 4, and then the process proceeds to S19.

  In S <b> 19, the CPU 71 reads from the ROM 72 the number of drive pulses of the image scanner left / right movement motor 52 that moves the image scanner 6 to the scan start position corresponding to the book size input via the operation unit 66. Then, the CPU 71 drives the image scanner left / right moving motor 52 by the number of driving pulses via the motor driving circuit 63, conveys the scanner timing belt 51 in the right direction, and moves the image scanner head 6 to the left side of the book 3. Opposite the edge.

  Subsequently, the CPU 71 reads from the ROM 72 the number of drive pulses of the image scanner left / right moving motor 52 that moves the image scanner 6 to the scan end position corresponding to the book size input via the operation unit 66. Then, the CPU 71 drives the image scanner horizontal movement motor 52 by the number of driving pulses via the motor driving circuit 63 and conveys the scanner timing belt 51 in the right direction. At the same time, the CPU 71 drives the image scanner head 6 via the drive circuit 67 and scans both pages of the book 3 to acquire image data. Then, the CPU 71 performs image data processing of both pages and stores the data in the RAM 73 as digital data information.

In S20, the CPU 71 reads the page count value P from the RAM 73, adds “1” to the page count value P, and stores the page count value P in the RAM 73 again.
Subsequently, in S21, the CPU 71 reads the page count value P and the page algebra N from the RAM 73, and whether or not the page count value P is equal to the page algebra N, that is, input via the operation unit 66 is repeated. A determination process for determining whether or not the number of pages has been turned is executed.

If it is determined that the page count value P is smaller than the page algebra N, that is, it is input via the operation unit 66 and the page turning is not performed (S21: NO), the CPU 71 The processing after S12 is executed again.
On the other hand, when it is determined that the page count value P is equal to the page algebra N, that is, it is input via the operation unit 76 and the page turning of the number of turning pages has been performed (S21: YES), the CPU 71 causes the operation unit 66 to Alternatively, after the digital data obtained by scanning the number of pages that have been input via the PC 77 is output to the PC 77 via the communication I / F 74, the processing is terminated.

  Here, the page separation shaft 16 functions as an example of a page separation member. Further, the page turning shaft 15 functions as an example of a turning member. Further, the drive current detection circuit 64 and the CPU 71 constitute an example of a movement inhibition detection unit. The CPU 71 functions as an example of a distance changing unit, a movement control unit, and a separation control unit. The page pressing shaft 17 functions as an example of a page pressing member. The image scanner head 6 functions as an example of an information acquisition unit.

  As described in detail above, in the book scanning apparatus 1 according to the first embodiment, the CPU 71 causes the page turning shaft 15 to contact the binding 3 </ b> B of the book 3 via the drive current detection circuit 64 to move the page turning shaft. When it is detected that it is obstructed, the page turning shaft vertical movement motor 42 is driven to move the page turning shaft 15 upward by a predetermined height. Thereafter, the CPU 71 drives the page turning shaft left / right movement motor 18 again to automatically move the page turning by moving the page turning shaft 15 in the direction of the binding 3B perpendicular to the binding 3B of the book 3. It can be carried out.

Further, since the page turning mechanism 5 can perform page turning by causing the page separation shaft 16, the page turning shaft 15 and the page pressing shaft 17 to face the page 3A to be turned, the number of parts of the page turning mechanism 5 is reduced. It becomes possible to achieve a simple apparatus configuration.
Furthermore, since the page turning shaft 15 only needs to be secured in the page turning mechanism 5 so that the page turning shaft 15 is not caught near the binding 3B of the book 3, the page turning mechanism 5 can be made thinner and smaller. As a result, the book scanning apparatus 1 can be reduced in thickness and size.

  In addition, since the turning shaft 15 can be moved upward by a predetermined height and the distance between the turning shaft 15 and the binding 3B portion of the book 3 can be changed, the opened book 3 is almost placed on the mounting table 4. Accordingly, the page turning mechanism 5 can be further reduced in thickness. Further, since the predetermined height to be moved above the page turning shaft 15 is changed in accordance with the paper quality (for example, hardness or thickness) of the book 3 pages, the page turning is performed in accordance with the paper quality of the page. The shaft 15 can be moved more reliably.

  In addition, the page separation shaft 16 can be moved in the direction of the binding line approaching the binding line 3B while the position of the binding line 3B side of the page separation shaft 16 of the page 3A to be turned is pressed by the page pressing shaft 17. Become. Accordingly, it is possible to reliably form the bulging portion 81 in which the page 3A to be turned bulges upward between the page pressing shaft 17 and the page separation shaft 16.

  Further, the page pressing shaft 17 and the page separating shaft 16 are changed by changing the position of the page pressing shaft 17 to press the page to be turned according to the size and paper quality of the book 3 placed on the mounting table 4. It is possible to adjust the interval. Thereby, it is possible to more reliably form the bulging portion 81 in which the page 3A to be turned bulges upward between the page pressing shaft 17 and the page separation shaft 16.

When the page turning shaft 15 enters the bulging portion 81 formed on the page 3A to be turned, the page pressing shaft 17 and the page separating shaft 16 are separated from the page 3A to be turned. It is possible to turn the page without damaging the page 3A.
Further, in the book scanning apparatus 1, the page turning mechanism 5 automatically turns the pages of the book, and all or a part of the pages of the book 3 opened and placed on the mounting table 4 via the image scanner head 6. The contents described on the page can be acquired as digital data.

  Next, a book scanning apparatus 91 according to the second embodiment will be described with reference to FIGS. The same reference numerals as those of the book scanning apparatus 1 according to the first embodiment denote the same or corresponding parts as those of the book scanning apparatus 1 according to the first embodiment.

The schematic configuration of the book scanning apparatus 91 according to the second embodiment is substantially the same as that of the book scanning apparatus 1 according to the first embodiment. Various control processes of the book scanning apparatus 91 are also substantially the same control processes as those of the book scanning apparatus 1 according to the first embodiment.
However, as shown in FIG. 23, the book scanning apparatus 91 is provided with a mounting table 92 configured such that the upper surface portion can be bent downward at the center in the left-right direction, instead of the mounting table 4. The mounting table 92 includes a left mounting plate 92A and a right mounting plate 92B having substantially the same size, and opposite side edge portions of the left mounting plate 92A and the right mounting plate 92B are connected by a hinge. Has been.

  And the center part of the front-back direction of the side edge part which the left mounting board 92A and the right mounting board 92B mutually oppose is supported by the support | pillar 95 by which the rack 93 was formed in the side part instead of the support | pillar 8. . Further, the support column 95 is configured to be movable downward from a through hole (not shown) provided in the bottom surface portion of the frame 2. The rack 93 formed on the side surface of the support column 95 meshes with a pinion gear 97 fixed to the motor shaft of the mounting table vertical movement motor 96 fixed to the bottom surface of the frame 2.

  The mounting table vertical movement motor 96 is configured to be driven via a motor drive circuit 63, and a drive current value is detected by a drive current detection circuit 64. Further, the mounting table vertical movement motor 96 is configured by a stepping motor or the like with a built-in encoder, and is configured to be able to detect the rotation angle and the origin position. Further, each leg 7 has, at its upper end, both corners of the left edge portion of the left placement plate 92A and both corner portions of the right edge portion of the right placement plate 92B, and the left placement plate 92A. The right mounting plate 92B is rotatably supported so that it can swing in the vertical direction.

  Accordingly, by rotating the mounting table vertical movement motor 96 by a predetermined number of driving steps in the clockwise direction when viewed from the front, the support column 95 is moved downward by a predetermined height, and the central portion in the left-right direction of the mounting table 92 is moved downward by a predetermined height. (See FIG. 26). In addition, when the mounting table vertical movement motor 96 is rotated again by a predetermined number of driving steps in the counterclockwise direction when viewed from the front, the top surface of the mounting table 92 is substantially horizontal when the support column 95 is moved upward. It is configured to be in a state.

  In addition, a recessed portion having a predetermined width is formed over substantially the entire width of the upper surface portion of the side edge portions of the left mounting plate 92A and the right mounting plate 92B facing each other. As a result, a vertically long rectangular groove (not shown) in a plan view formed so that the back portion of the book fits in the longitudinal center position of the upper surface portion of the mounting table 92 is substantially orthogonal to the longitudinal direction. It is formed over almost the entire width.

  Next, “page scanning process 2” in which the opened book is turned by the book scanning apparatus 91 configured as described above and scanned will be described with reference to FIGS. Note that the program shown in the flowchart of FIG. 24 is stored in the ROM 72 of the book scanning apparatus 91 and is executed by the CPU 71 when a start button (not shown) of the operation unit 66 is pressed.

As shown in FIG. 24, in S111 to S116, the CPU 71 executes the processes of S11 to S16.
Then, as shown in FIG. 25, the drive current value of the page turning shaft left / right moving motor 18 suddenly increases, the page turning shaft 15 hits the binding 3B of the book 3, and the movement of the page turning shaft 15 is inhibited. When it is determined that it has been (S116: YES), the CPU 71 proceeds to the process of S117.

  In S117, as shown in FIG. 26, the CPU 71 first stops the page turning shaft left / right movement motor 18, and temporarily stops the movement of the page turning shaft 15 toward the binding line 3B. Thereafter, the CPU 71 moves the support column 95 downward by a predetermined height corresponding to the paper quality of the book 3 (for example, thick (hard), normal, thin (soft), etc.) input via the operation unit 66. The number of driving pulses of the mounting table vertical movement motor 96 is read from the ROM 72. The number of driving pulses of the mounting table vertical movement motor 96 that moves the support column 95 downward by a predetermined height corresponding to the paper quality of the book 3 is stored in the ROM 72 in advance.

  For example, when the paper quality of the book 3 is thick (hard), the CPU 71 reads from the ROM 72 the number of driving pulses of the mounting table vertical movement motor 96 that moves the support column 95 downward by about 10 mm. When the paper quality of the book 3 is normal, the CPU 71 reads from the ROM 72 the number of driving pulses of the mounting table vertical movement motor 96 that moves the column 95 downward by about 5 mm. Further, when the paper quality of the book 3 is thin (soft), the CPU 71 reads from the ROM 72 the number of driving pulses of the mounting table vertical movement motor 96 that moves the column 95 downward by about 3 mm.

  Then, the CPU 71 rotationally drives the mounting table vertical movement motor 96 by the number of drive pulses read from the ROM 72 to move the support column 95 downward by a predetermined height corresponding to the paper quality, so that the central portion of the mounting table 92 is moved to a predetermined height. After moving downward, the processes after S115 are executed again. That is, as shown in FIG. 26, the CPU 71 drives the page turning shaft left / right movement motor 18 again via the motor drive circuit 63, so that the page turning shaft 15 is perpendicular to the binding 3 </ b> B of the book 3. Move in the 3B direction. At the same time, the CPU 71 continuously counts the number of drive pulses of the page turning shaft left / right movement motor 18 and stores it in the RAM 73 as a “movement count value”.

  On the other hand, when it is determined in S116 that the page turning shaft 15 does not hit the binding 3B of the book 3 and the movement of the page turning shaft 15 is not hindered, that is, the page turning shaft left-right movement motor 18 When the drive current value does not increase rapidly (S116: NO), the CPU 71 proceeds to the process of S118. In S118, the CPU 71 executes the process of S18.

If it is determined that the page turning shaft 15 has not moved to the page turning end position, that is, if the “movement count value” is less than the “number of movement end pulses” (S118: NO), the CPU 71 again , S115 and subsequent processes are executed.
On the other hand, as shown in FIG. 27, when it is determined that the page turning shaft 15 has moved to the page turning end position, that is, when the “movement count value” is equal to or greater than the “number of movement end pulses” (S118: YES), the CPU 71 determines that the page turning is finished, and stops the page turning shaft left / right moving motor 18 via the motor drive circuit 63.

  Thereafter, the CPU 71 drives the page turning shaft left / right movement motor 18, the page separation shaft left / right movement motor 25, and the page pressing shaft left / right movement motor 32 via the motor drive circuit 63, respectively, and the page turning shaft 15, page separation shaft 16. The page pressing shaft 17 is moved in the right direction of the frame 2 until the page pressing shaft 17 is located outside the right end edge portion of the mounting table 92, and then the process proceeds to S119.

  In S119, the CPU 71 drives the mounting table vertical movement motor 96 via the motor driving circuit 63 to move the support column 95 to the uppermost position, thereby bringing the left mounting plate 92A and the right mounting plate 92B into a horizontal state. When the support column 95 is moved to the uppermost position, a stop portion (not shown) provided at the lower end portion of the support column 95 hits the bottom surface of the frame 2 and the drive current value of the mounting table vertical movement motor 96 increases rapidly. Therefore, the CPU 71 determines that the support column 95 has moved to the uppermost position, and stops the mounting table vertical movement motor 96.

  Subsequently, the CPU 71 reads from the ROM 72 the number of drive pulses of the image scanner left / right movement motor 52 that moves the image scanner 6 to the scan start position corresponding to the book size input via the operation unit 66. Then, the CPU 71 drives the image scanner left / right moving motor 52 by the number of driving pulses via the motor driving circuit 63, conveys the scanner timing belt 51 in the right direction, and moves the image scanner head 6 to the left side of the book 3. Opposite the edge.

  Subsequently, the CPU 71 reads from the ROM 72 the number of drive pulses of the image scanner left / right moving motor 52 that moves the image scanner 6 to the scan end position corresponding to the book size input via the operation unit 66. Then, the CPU 71 drives the image scanner horizontal movement motor 52 by the number of driving pulses via the motor driving circuit 63 and conveys the scanner timing belt 51 in the right direction.

At the same time, the CPU 71 drives the image scanner head 6 via the drive circuit 67 and scans both pages of the book 3 to acquire image data. Then, the CPU 71 performs image data processing of both pages and stores the data in the RAM 73 as digital data information.
Thereafter, in S120 and S121, the CPU 71 executes the processes of S20 and S21 and ends the process.

  As described in detail above, in the book scanning apparatus 91 according to the second embodiment, the CPU 71 causes the page turning shaft 15 to contact the binding 3B of the book 3 via the drive current detection circuit 64 and move the page turning shaft 15. When it is detected that the movement is inhibited, the mounting table vertical movement motor 96 is driven to move the support column 95 downward by a predetermined height, and the horizontal center of the mounting table 92 is moved downward by a predetermined height. . Thereafter, the CPU 71 drives the page turning shaft left / right movement motor 18 again to automatically move the page turning by moving the page turning shaft 15 in the direction of the binding 3B perpendicular to the binding 3B of the book 3. It can be carried out.

  In addition, since it is only necessary to secure a height within the frame 2 that allows the central portion in the left-right direction of the mounting table 92 to be moved downward by a predetermined height, the book scanning apparatus 1 can be reduced in thickness and size. It becomes. Further, in order to change the predetermined height by which the support column 95 is moved downward in accordance with the paper quality (for example, hardness or thickness) of the page of the book 3, the page turning shaft 15 corresponds to the paper quality of the page. Can be moved more reliably.

  In addition, this invention is not limited to the said Example 1 and Example 2, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.

  (A) For example, a page separation shaft rotation motor configured by a stepping motor or the like that rotationally drives the page separation shaft 16 to the separation shaft support portion 45 and rotatably attaches the page separation shaft 16 to the separation shaft support portion 45. You may make it provide. In S13, the CPU 71 rotates the page separation shaft 16 by a predetermined angle to move the page 3A to be turned by a predetermined distance in the direction of the binding 3B. The number of pulses is read from the ROM 72.

  Subsequently, the CPU 71 may rotate the page separation shaft 16 by a predetermined angle by rotating the page separation shaft rotation motor by a predetermined number of drive pulses read from the ROM 72. Accordingly, it is possible to form a bulging portion 81 in which the page 3A to be turned of the book 3 is bent upward between the page separation shaft 16 and the page pressing shaft 17.

  (B) Further, for example, an encoder mark is printed on the outer peripheral surface of the turning timing belt 11 in addition to the reflection mark 21 on the entire circumference at a predetermined pitch, and the encoder mark is detected by the origin position detection sensor 22. In addition, an inhibition of the movement of the turning timing belt 11 (for example, a decrease or stop of the moving speed) may be detected.
