Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is configured such that a feed roller is installed at a position 1u close to the original document placement glass, and after the scanning of the document is completed, the document is ejected from the upper surface of the document placement glass by the feed roller. The present invention relates to a copying machine.

Conventionally, when copying a plurality of sheet originals, a copying apparatus opens a pressure plate 21 as shown in FIG.
The original 23 is placed on the plate, the pressure plate 21 is closed, and a start switch (not shown) is turned on. By this input, an optical device (not shown) scans the original and copies it.
After scanning the original, the pressure plate 21 is opened, the original 23 is picked up by hand and placed at a different position θ], and a new original sieve 23 is placed on the original placing glass 22. This operation is used to perform stock return copying work.

When copying a plurality of sheet originals in this manner, it is necessary to manually pick up the original on the original placing glass and place it somewhere else after the scanning of the optical device is completed, making the operation of replacing the original original complicated.

An object of the present invention is to provide a copying apparatus fltf that can reduce the number of operations described above.

Embodiments of the present invention will be described below based on the drawings.

1 is a copying machine, 2 is a document placement glass, 4 is a drive roller that is pivotally supported by a pair of first support members 6 provided on the bottom surface of the top plate 5 of the copying machine main body; The surface of the roller slightly protrudes from the m140 section 7, and the driving means for the drive roller is connected to the paper ejection drive roller via a gear or the like, and is driven to rotate for a certain period of time after scanning the document. A roller 8 is pivotally supported by a pair of second support members 9 provided on the top surface of the top plate 5 and is connected to a drive roller;
10 is a pressure plate, and 11 is a document tray.

Next, a method of using the embodiment configured as described above will be explained.

First, as shown in Fig. 2, open the pressure plate 10, place the bucket S on the glass 2 for placing the plate 1', and close the pressure plate 10i.Then, when you turn on the start switch (not shown), , an optical system (not shown) scans the entire document and copies it. After the scanning is completed, the pressure plate 10 is opened to the fullest extent.
The document S is shifted and its leading end is inserted into the joint surface between the drive roller 4 and the roller 8. Since the driving roller 4 and the roller 8 are rotating for a certain period of time after the scanning of the optical system is completed, the original it, a
The raw material P1 is ejected from the tray (Ic) by the drive roller 4 and the roller 8. Then, a new document S is placed on the document placement glass.Then, by repeating the same operation as above, the Make a copy of the original 4S.

Although the drive roller 4 has been described as rotating for a certain period of time after the optical system finishes scanning, it may be configured to rotate constantly during nuclear copying, and its drive source may be taken from the drive unit of the copying machine main body. Alternatively, a separate motor percentage may be used.

Figure a34 shows another embodiment, in which the pressure plate 10'θ]
One end of the frame 15 is pivotally supported by a support member 16, and a roller 8' is attached to a support member 18 provided on a protrusion 17 extending rearward 111iI (to the left in FIG. 4) from the one end.
is rotatably supported, and when the pressure plate 10' is opened, the roller 8' or the roller 4 comes into contact with the roller 0'.
].

When opening and closing the small pressure plate 10', the pressure plate 10' may be brought into contact with and separated from the roller 8' or the roller 4 independently, and when the pressure plate 10' is removed from the case 5, it may be removed together.

Good too.

Use foam material (sponge) or brush (bristle) to remove the rolled rollers 8 and 8'.
By using a shade, it is possible to prevent damage to the document in the event of a jam, and it is possible to effectively correct the skew.

As described above, in the present invention, a pair of feed rollers consisting of a drive roller and a secondary υ roller combined with the drive roller are placed on a cliff near the document placement glass, and the joint portion of both rollers is connected to the document placement glass surface. The drive rollers are installed at approximately the same position, and the driving roller is driven at least at a fixed time r=j after the scanning of the original is completed. Placed original +1
1 can be ejected to the original 4 by simply swiping 4 with your hand, which simplifies the operation of replacing originals. Also, since the feed roller only needs to be reinstalled, it is inexpensive. It has the effect of being able to be manufactured.
