Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic document page turning device disposed in a copying machine or the like that copies a thick document such as a book by placing it face up.

[Conventional technology]

Conventionally, pages of thick originals such as books have been automatically turned over. For example, suction-type devices and robot-type devices have been proposed.

[Problem that the invention attempts to solve]

All of the conventionally proposed devices have complicated mechanisms and controls, resulting in high manufacturing costs.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic document page turning device that has a simple mechanism and control, and can reduce manufacturing costs.

[Means and effects for solving the problem] The present invention provides a document mounting table on which a book or the like is placed facing upward, and is provided with locking claws for locking the paper surfaces at both ends of the document, and which is installed vertically on the document mounting table. An arm is attached to the base that can be rotated and raised up and down, and a suction device for suctioning the manuscript paper is suspended from this arm.Furthermore, a blower device is installed on both sides of the manuscript, so that the document can be sucked by the suction operation of the suction device. The pages are turned over by blowing air onto the original paper using a blower.

In FIG. 1, (A) is an automatic document page turning device;
A thick original (a) such as a book is placed approximately in the center of the original placing table (11). Various parts of the automatic document page turning device (A) are arranged around the device.

That is, a support (2) containing a built-in gear for driving the arm is installed near the binding part (bl) of the thick document (a), and the arm (2) is moved horizontally to a predetermined height of the support (2). 3) is provided. This arm (3) is designed to be able to pivot horizontally and raise and lower vertically. At the tip of this arm (3) is a suction device ( 4) is suspended. This suction device (4) is formed in a cylindrical shape, and the lowermost part of the suction device (4) comes into contact with the paper surface of a thick document (aluminum), so that the document paper is suctioned by air suction. When the suction device (4) comes into contact with the surface of a thick document (al), the arm (3) is lowered by the downward movement of the arm (3). A compression coil spring (5) is interposed between the suction device (4) and the support (2).A drive device (6) consisting of a motor etc. is connected to the column (2). The arm (3) is oscillated in the horizontal and vertical directions by the operation of the device (6), and the suction device (4) sucks air to suction the thick document + a) document paper. .

Furthermore, two air blowers (71, (8) facing each other are installed on the left and right sides of the thick document fal, and the air blowing ports (7a) and (8a) thereof face each other and blow air in the horizontal direction. Both of these two air blowers T7) and (81) are connected to the fan (9).In addition, these two air blowers (7) and (81 are connected to each other in order to use only one of them. , and the passage with the fan (9) are both openable and closable.

Furthermore, there are document locking claws Ql, (11) on both sides of the thick document (al) that can be opened and closed to lock the paper surface.The document locking claws Ql, (11) are made of soft material such as vinyl. horizontal plates (10a), (lla) and vertical plates (10b)
).

(11b), horizontal plate (10a), (1
1 and a) can be opened and closed by a device not shown.

With the above configuration, the pages of the thick original (a) are turned over in the following order of operations. That is, as shown in FIG. 2, the arm (3) is initially positioned directly above the thick original (Al bound Koriyama). In this state, place the thick original (al) on a horizontal board (10
a), (lla) to lock and set. Next, the page of the thick document (al) is selected and the drive unit W (6) is activated to rotate the arm (3) in the horizontal direction. There is also an arm (3
) to bring the suction device (4) into close contact with the paper surface. At this time, contact is ensured by the bias of the compression coil spring (5). In this state, the drive device (6) is operated and the suction device (
4) The original paper is sucked by the suction force of the air.

At the same time, the arm (3) is raised as shown in FIG. If the second sheet of manuscript paper is attached at this time,
In order to prevent double turning, the horizontal plate (10a) is left in a half-open state, and the flexibility of vinyl is used to lock the second sheet of original paper with the horizontal plate (10a). Next, the manuscript paper is placed in the air outlet (7
a) When the fan (9) automatically blows air, the operation of the suction device (4) is automatically stopped, and as shown in Figure 5, the manuscript paper is blown by the air. The page is skipped and the page is turned.

Note that at this time, the passage from the fan (9) to the blower device (8) is in a closed state. Also, horizontal plate (11a)
is opened at the same time as air is blown in order to lock the turned up manuscript paper.

If double-folding cannot be prevented, the arm (3
) can be moved to the opposite side and activated the device on the opposite side to correct it.

In addition, in order to correspond to the size and thickness of the thick original (al), the horizontal plate (10a) of (11) of the original locking claw α is
), (lla) and vertical plates (10b), (llb)
can also be configured to be movable up and down and left and right.

〔Effect of the invention〕

As explained above, according to the present invention, an arm is provided on the original placing table so as to be able to rotate and raise it up, and a suction device provided on the arm and a suction device provided on the original placing table and a suction device provided on the original placing table are attached to the original placing table. 1. Since the apparatus is configured to turn the pages of the page, the mechanism and control are simple, and the manufacturing cost of the apparatus can be reduced. Furthermore, compared to conventional systems with complex mechanisms and controls, the system is easier to operate and has a lower failure rate.
