Abstract

PURPOSE:To simplify a structure and operation control by providing a hollow rotary body having a large number of suction holes opened to the outer peripheral surface thereof and the internal space communicating with those suction holes in opposed relation to bound paper sheets so as to connect the same to a rotary drive part and providing the negative pressure generating part connected to the internal space of the rotary body. CONSTITUTION:A belt 5 is allowed to approach paper sheets 1 on the right-hand side of a bound part 1a and, by driving a blower 9, the friction between the belt 5 and the paper sheets 1 can be enhanced by the negative pressure acting on suction holes 6. When the belt 5 is rotated in a clockwise direction by driving a motor 7, the paper sheets 1 on the right-hand side of the bound part 1a is allowed to approach leftwardly and, when the belt 5 is further rotated, page turning-over can be completed. As mentioned above, since the operation necessary for page turning-over is performed only by rotating the belt 5, a structure and operation control can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a page turning device for turning over bound sheets of paper.

It is difficult to manually turn the pages with a scanner that copies paper industry entries that are bound on one side, such as conventional technical books, or with a photographic device that makes microfilm of the same entries. It's annoying.

For this purpose, there is an invention described in Japanese Unexamined Patent Publication No. 57-205197. In this invention, a suction cup connected to a blower is provided at the tip of a movable body having at least three joints which are each rotated by a motor, and the movement of the joints brings the suction cup into contact with paper sheets and sucks them. be.

Problem to be solved by the invention The invention described in Japanese Patent Application Laid-open No. 57-205197 is as follows:
Since at least three joints must be moved by motors, the structure and control of each motor become complicated, leading to an increase in cost.

Means for Solving the Problems The invention as claimed in claim 1 provides a hollow rotating body that faces bound paper sheets and has a large number of air intake holes opening on the outer peripheral surface and an internal space communicating with these air intake holes. A negative pressure generating section was provided connected to the rotation drive section, and a negative pressure generating section connected to the internal space of the rotating body.

The invention of claim 2 connects a hollow rotary body having a large number of intake holes opening on the outer circumferential surface and an internal space communicating with these intake holes and facing the bound paper sheets to a rotation drive unit. and a negative pressure generating section connected to the internal space of the rotating body, having a rotational axis parallel to the rotating body, being held movably back and forth in the axial direction, and being turned over by the rotating body. A roller inserted under the sheet of paper was connected to a second rotational drive unit that rotated in the same direction as the rotational direction of the rotating body.

The invention of claim 1 provides the following effects by driving the negative pressure generating section.
The friction between the rotating body and the paper sheet can be increased by the negative pressure acting on the intake hole, and by driving the rotation drive unit, pages can be turned with only one direction of rotation of the rotating body. This allows the structure and operation control to be simplified.

In addition to the above-mentioned effect, the invention of claim 2 provides that when the rotary body turns over a plurality of sheets of paper, by advancing the roller and driving it with the second rotation drive section, the lower side of the sheet is turned over. The lower surface of the sheet can be brought into contact with the rotating roller and returned, thereby preventing double feeding.

Embodiment A first embodiment of the present invention will be explained based on FIGS. 1 and 2. l is a number of sheets of paper bound on one side like a book. Reference numeral 2 denotes opposing frames, and two rollers 3.4 are rotatably held at both ends of these frames 2, and a belt 5, which is a rotating body, is wound around these rollers 3.4. .

This belt 5 has two layers, an inner circumferential surface and an outer circumferential surface, an internal space is formed between the two layers, and both side edges of the two layers are sealed. A large number of air intake holes 6 are formed on the outer peripheral surface of the belt 5. Further, a motor 7 which is a rotational drive unit for driving the roller 4 is fixed to the frame 2 on one side, and one end of a hose 8 connected to the internal space of the belt 5 is fixed. The tip is connected to a blower 9 which is a negative pressure generating section.

In such a configuration, for example, by bringing the belt 5 close to the paper sheet 1 on the right side with the binding section 1a as a boundary and driving the blower 9, the belt 5 and the paper sheet are moved by negative pressure acting on the intake hole 6. It is possible to increase the friction with 1. Furthermore, when the motor 7 is driven to rotate the belt 5 clockwise, the paper sheet l on the right side of the binding section 1a is moved to the left as shown in FIG. 2(a), and the belt 5 is still When you rotate ,
Page turning can be completed through the state shown in FIG. 2(b). In this way, since the only action required for page turning is to rotate the belt 5, the structure and operation control can be simplified.

As shown in FIG. 3, by restricting the area where the air intake holes 6 are formed to a part of the belt 5, the suction force against the paper sheet 1 can be increased and the page turning action can be promoted.

Next, a second embodiment of the present invention will be described based on FIG. 4. Components that are the same as those in the embodiment described above are designated by the same reference numerals, and description thereof will be omitted (the same applies hereinafter). A cover 10 covering approximately half the upper circumferential surface of the belt 5 is fixed to the frames 2 on both sides. Further, a roller 11 having a rotational axis along the width direction of the belt 5 is connected to a drive unit (not shown) such as a cylinder, and is provided so as to be movable forward and backward in the axial direction. One end of this roller 11 is directly connected to a motor 12, which is a second rotational drive unit, held by a frame (not shown).

In such a configuration, the paper sheet l is attracted by the rotating belt 5 and turned over from the right to the left, but since the upper half circumference of the belt 5 is covered with the cover 10, the air intake at the lower surface of the belt 5 is The suction force from the holes 6 can be increased. Further, as shown in FIG.
2, when two sheets 1 are turned over so as to overlap, the upper sheet 1 is sent to the left by the belt 5, while the lower sheet 1 is moved to the right side by the roller. can be returned to. In other words, double feeding of paper sheets 1 can be prevented.

Furthermore, a third embodiment of the present invention will be described based on FIGS. 5 to 7. A roller 14, which is a rotating body, is rotatably supported by bearing members 13 facing each other. A large number of air intake holes 6 are formed on the outer peripheral surface of the roller 14, and an internal space (not shown) communicating with these air intake holes 6 is formed inside.

Therefore, by driving the blower 9 and rotating the roller 14 clockwise with the motor 7, the sheet 1 can be turned over from right to left. - When turning over the paper leaf l with the book roller 14, the necessary feed amount can be obtained by bringing the roller 14 into contact with the vicinity of the binding portion 1a of the paper leaf l. At this time, since the connecting part 15 of the roller 14 and the vibrator 17 connected to the hose 8 are fitted through the O-ring 19, the airtightness of the fitting part is improved and the rotation of the vibrator 17 and the hose 8 can be prevented from twisting. Furthermore, as shown in FIG. 7, by making the outer diameter of the roller 14 thinner, it is possible to read the image of the paper sheet l or
The roller 14 does not get in the way during photography.

Furthermore, as shown in FIG. 8, a cover 20 covering the upper half circumference of the roller 14 is fixed to the bearing member 13, or as shown in FIG. 9, an intake hole 6 is formed in a part of the roller 14. The suction force of the roller 14 against the paper sheet 1 can be increased by means such as the above. Note that roller 1 is used as a rotating body.
4, the roller 11 shown in FIG.
can be used in combination to prevent double feeding of paper sheets 1.

Furthermore, a fourth embodiment of the present invention will be described based on FIG. 10. An arm 21 that rotatably holds both ends of the roller 14 is swingably provided.

These arms 21 are urged in one direction by a spring 22 and are rotatably connected to the tip of a plunger of a solenoid 23. Furthermore, stoppers 24 are fixedly provided on both sides of the arm 21 to limit the range of rotation of the arm 21.

Therefore, when turning paper sheet 1 from the right to the left, the first
