で右方に送り出す。 In general, the functions of such an automatic document feeder 1 include, as shown in FIG. The signal is input to the copying machine 4 side. After that, when the copy start button of the copying machine 4 is operated, the paper feed rollers 5 and 6 and the paper feed belt 7 are activated.
rotates in the direction of the arrow, and in cooperation with the stop roller 8 for preventing multi-layer feeding, the document 3 is sent out one by one to the right in the figure.

接し、原稿３を確実に搬送する。 The sent document 3 is transferred to the document feeding belt 9, which has started rotating in the direction of the arrow by the copying start operation, and the presser roller 1, which rotates following the movement of the document feeding belt 9.
0 and 11 onto the document table 12, and is conveyed as the document transport belt 9 rotates until the leading edge of the document 3 abuts the stopper 13. At this time, the pressure roller 3 provided on the upper surface of the binding belt 9
4 brings the feeding belt 9 into pressure contact with the document mounting table 12, thereby transporting the document 3 reliably.

る。 When the conveyance is completed and the document 3 is located in the exposure area, the copying machine 4 starts exposure, and when the exposure ends, the stopper 13 moves diagonally downward to the left, and immediately after that, the document feeding belt starts rotating. The copied original 3 is ejected onto the original ejection tray 15 by the ejecting roller 9 and the ejecting roller 14 which rotates in accordance with the movement of the ejecting roller 9 .

ることが是非とも必要である。 As is clear from the above, an automatic document feeder is generally equipped with a large number of rotatable rollers supported by frame side plates to perform various operations, and a document feeder consisting of one or more rollers used to transport documents. A conveying belt is stretched between the conveying rollers. In such an automatic document feeder, as described above, the document is conveyed by the document feed belt, sent onto the document tray that makes light surface contact with the belt, and is placed on the glass surface of the document tray. It is crimped. Therefore, in order to accurately convey the original onto the original platen, it is absolutely necessary to maintain the pressure of the original feed belt against the glass surface of the original platen with high precision.

れたりすることがある。 In other words, the pressure between the glass surface of the document placement table and the document feed belt, or even the gap between the paper binding belt and the document placement table, may not be maintained accurately and the surface may not be in contact with the feed belt (there may be a gap on one side). A) If the pressure is uneven, the document may not be fed smoothly, or the document may be conveyed bent to the exposure position.

法は見当らない。 A structure for releasably attaching such an automatic document feeder to a copying machine is disclosed in, for example, Japanese Patent Laid-Open No. 73768/1983. However, in the mounting structure as disclosed in the above-mentioned publication, there is no other way to control the pressure between the document feed belt and the glass surface of the document table of the copying machine other than depending solely on the precision of the parts.
しかし部品精度に依存する方法は実際的には非

It is an object of the present invention to provide an adjustment fixing means that can be accurately and easily performed.

成することができる。(Means for Solving the Problems) According to the inventors of the present invention, the above problems are solved by the fact that the fixing bracket member 21 provided near the document table 12 on the upper surface of the copying machine main body 4 is pivotable on the shaft 22. A document feeder 1 is provided with a movable bracket member 24 connected to a frame supporting a document transport means 9 which is supported and arranged so as to be openable and closable with respect to the surface of a document placement table 12.
The fixed bracket member 21 and one end of the movable bracket member 24 are rotationally engaged with each other by a shaft, and a spring member 23 is provided for biasing the movable bracket member 24 in the opening direction, and the movable bracket member 24 is attached to a copying machine. A fixing member 31 that can be tightened to the main body 4, a frame body that accommodates the document conveying means, and the movable bracket member 24.
Adjustment member 30 that adjustably fixes the relative position with
are arranged on the movable bracket member 24, and the movable bracket member 24 is temporarily fixed to the copying machine main body 4 by the fixing member 31 with the document transport means 9 closed with respect to the document mounting table 12. , With the lower surface of the document conveying means 9 and the upper surface of the document mounting table 12 brought into close contact, the relative position between the frame of the document conveying means and the movable bracket member 24 is adjusted and fixed by the adjustment member 30. This can be achieved by a method for attaching and adjusting a document feeding device characterized by the following.

FIG. 2 is a schematic perspective view showing an embodiment of a copying machine equipped with an automatic document feeder (hereinafter referred to as document feeder) according to the present invention. Original table 12
The document feeder 1, which can be opened freely with respect to the glass surface of the copying machine 4, can be stopped at any opening angle by a pair of support members 16A and 16B that are appropriately spaced from each other on the rear side of the upper surface of the copying machine 4.

This shaft 22 is provided with a groove, into which one end 23a of the spiral spring 23 is fitted. A U-shaped bracket 24, which can be rotated about this shaft 22, is also fitted.

せることができる。 The other end of the spiral spring 23 is fixed to this U-shaped bracket 24 together with a spiral spring fitting 25.
The U-shaped bracket 24 is attached to a connecting plate 26 fixed to the base of the document feeder 1. As is clear from the above configuration, since the above-described device uses a spiral spring, a light movement is sufficient when opening the document feeder 1, which has a relatively large moment with respect to the shaft 22. Furthermore, a spring washer 27 made of a spring or a resin in which a spring is embedded is inserted between the mounting bracket member 21, which is a fixed member, and the mounting bracket member 24, which is a rotating member, so that the above-mentioned moment and restoring force of the spiral spring can be adjusted. Since the thrust friction is generated to have a value slightly larger than the difference between the opening and closing operation, the opening/closing operation can be reliably stopped at any opening degree without increasing the force required for the opening/closing operation.

けることが効果的である。 Further, during exposure, it is necessary that the original 3 is pressed and tightly attached to the glass surface of the original placing table 12.
When the opening angle of the document feeder 1 is 0° C., the document feeder 1 is preferably in pressure contact with the glass surface of the document placement table 12. For this reason, the document feeder 1
A ferromagnetic material such as a magnet or iron is provided at the inner free end of the copying machine 4 (28 in FIG. 2) when the document feeder 1 is closed. It is effective to provide a ferromagnetic material or a magnet.

置１が急速に開くのを防止する。 Furthermore, the maximum opening angle of document feeder 1 is 90 degrees.
When the temperature is around ℃, the restoring force of the spiral spring becomes larger than the moment, causing it to open rapidly, which is dangerous for operation and causes a large impact. To prevent this, install the mounting bracket 2, which is a fixed part.
A leaf spring 29 is attached to the bottom of the document feeder 1, and the structure is such that a large spring pressure is generated between the leaf spring 29 and the U-shaped bracket, which is a rotating part, when the opening angle of the document feeder 1 is about 90 degrees. That is, when the document feeder 1 is opened to nearly 90 degrees, the bent end portion 25a of the fixture 25 comes into contact with the leaf spring 29, and the elastic force of the leaf spring 29 prevents the document feeder 1 from opening rapidly.
