5. Solenoid 59 for protruding the turning rod 63
The operation is controlled by a control circuit (not shown), and the page turning operation is performed as described below.

The case of a book in which the number of pages increases from the left side to the right side (that is, the case where the right page is turned to the left side) will be explained.

To place the book 90 on the mounting table 5, the heights of the halves 5a and 5b are adjusted by the seesaw mechanism 6 so that the book 90 is spread open so that the left and right sides of the book 90 are at the same height.

As shown in FIG. 6, after both the left and right pages of the book 90 placed on the mounting table 5 in the form of a double-page spread are read by the optical character reading device 80, the mounting table 5 is moved downward by the lifting device 2. descends to the presser members 7a, 7
b advances forward by moving the moving table 8 and moves to the seventh
As shown in Figures a and b, the left and right pages of the book 90 are held at positions near the center.

Next, as the timing belt 27 is driven by the motor 22, the right moving body 30 moves to the left along the guide rod 17, and as shown in FIG. The book 90 is stopped so that it is located slightly inside the right edge of the right page 91. This stopping position is determined according to the size of the book 90 detected by the detection device 10 provided on the mounting plate 9 of the mounting table 5.

Further, in accordance with the detected dimensions of the book 90, the second arm 54 moves the position sensor 5 so that the turning bar 63 is positioned approximately at the center of the right page 91.
7 and is rotated in a predetermined direction by the rotation of the motor 55. When the second arm 54 reaches a predetermined position, the control circuit stops the rotation of the motor 55 in response to a signal from the position sensor 57, thereby setting the turning bar 63 at approximately the center of the right page 91. .

Next, as shown in FIG.
The turning roller 46 comes into contact with it. At this time, as the mounting table 5 rises, the first arm 39 rotates counterclockwise (see FIG. 4) against the tension spring 42, and the sensor arm 4 at the upper end of the first arm 39 rotates.
4 reaches the sensor 45, the sensor 45 outputs a detection signal. This detection signal causes the lifting device 2 to
The lifting and lowering of the mounting table 5 is stopped.

Next, the pulse motor 48 operates, and the gears 49,
50, the belt 52 causes the turning roller 46 to start rotating in the clockwise direction as shown in FIG. Since the turning roller 46 is pressed against the page by the biasing force of the tension spring 42, sufficient frictional force is applied to the page. Therefore, as shown in FIG. 9, the right page 91a slides in the direction of the binding line 90a and bends so that the center bulges upward, and the next page 91a
1b, the turning roller 46 stops rotating. During this time, the right moving body 30
If it is moved slightly to the left, the bulge will occur more easily.

Next, the solenoid 59 operates and the plunger 5
9a moves in the direction of the second arm (in FIG. 5). As a result, the turning rod 63 projects forward through the rotating plate 61 and is inserted into the gap between the right page 91a and the next page 91b.

Next, the holding members 7a and 7b, which were holding the book 90 in a double-page spread shape, are moved toward the vertical substrate 1 by the movable body 8 and removed from the book 90.

Next, by driving the motor 22, the right moving body 30
moves to the left as shown in FIG. By this movement, the page 91a is pasted the book binding 90a.
is carried to the left page side, and as shown in FIG. 11, the page 91a slips between the turning roller 46 and the turning bar 63 and falls to the left side of the book 90. In this way, one page is broken.

Next, the turning rod 63 retreats rearward, and the right moving body 30 moves to the right end of the guide rod 17, returning to the state shown in FIG. 1.

Next, the mounting table 5 is raised by the elevating device 2 and reaches the optical character reading device 80, and comes into contact with the lower surface of the optical character reading device 80, returning to the state shown in FIG. 6, and reading is performed.

After reading both the left and right pages of the spread,
As described above, the mounting table 5 is lowered again, and the operation of turning the right page to the left and the reading operation are repeated in the same manner.

While this page turning progresses sequentially, the half body 5
The seesaw mechanism 6 is operated so that the heights of the left half body 5b gradually decrease and the right half body 5a rises so that the two-page spread surfaces are always at the same height.

Contrary to the above, when changing the page from the left side to the right side, the left moving body 7 is replaced with the right moving body 30.
A similar operation is performed by 0.

In addition, as shown in FIG. 12, the turning roller 4
6 and the turning bar 63 may not be parallel to the binding line 90a of the book 90, but may be slightly inclined.

Further, the motor 55, the worm gear 56, and the position sensor 57 may be omitted and the second arm 54 may be fixed.

As explained above, in the automatic page turning device of the present invention, the turning roller is brought into contact with the book according to the size of the book, and the turning roller applies frictional force in the direction of the binding of the book, so that the pages to be turned are By inflating the center of the page, creating a gap between it and the next page, and inserting a turning stick into this gap, the page can be moved past the binding line.
Regardless of the size of the book, the quality of the paper, etc., it is possible to always accurately turn the pages one by one without turning blankly or turning multiple pages.
