Abstract

PURPOSE:To solve a problem that an original may be again wound in an ejection roller by reverse rotation of this roller after the ejection of the original by arranging a sensor for detecting the presence of the ejected original at the position of the ejection roller. CONSTITUTION:An original is held between a glass face 1 and a belt 2 and conveyed, then its rear end is brought into contact with a stopper 4 having a level difference by moving the belt 2 backward to situate the original at the exact prescribed position on the glass face 1. The copying action of the original executed at this position, then the belt 2 is again moved forward, the original is conveyed to the other end of the belt 2 on the original ejection side, and it is ejected with an ejection roller 6 arranged on the ejection side. In this ejection device, the roller 6 is linked with the belt 2 so as to move the roller 6 in the same direction of the belt 2 and to eject the original, and in order to prevent the original once ejected from being again wound in the roller 6 by the reverse rotation of the roller 6 at the time of reverse conveyance, a sensor 7 for detecting the presence of the original at the position of the roller 6 and stopping the device at once when the original is present is installed at the position of the roller 6.

が生じた。DETAILED DESCRIPTION OF THE INVENTION The present invention allows a conveyor belt to slide in contact with a glass surface of an original so that it can be driven forward and backward, and by rotating the belt in the forward direction, the supplied document from one end of the belt on the paper feeding side is conveyed onto the glass surface. Then, by reversing the belt, let the rear edge of the document hit the stopper,
After positioning the original on a predetermined glass surface and copying the original in this positioning state, the belt is rotated in the normal direction again to convey the original to the other end of the belt on the paper ejection side, and at the same time In particular, in the present invention, in order to simplify the drive means for the paper ejection roller, the paper ejection roller is linked to the drive of the conveyor belt, and the paper ejection roller is moved in the same direction as the belt. It is assumed that the paper is ejected by rotation in the direction, but if this configuration is adopted, it would be desirable for the ejection roller to remain in a stopped state after the original ejection. Since it is driven integrally with the conveyor belt, the paper ejection roller rotates in the opposite direction even after ejection, resulting in the problem that the trailing edge of the document once ejected sometimes gets caught in the paper ejection roller. .

その特長は大きい。As described above, according to the present invention, the drive means for the paper ejection rollers can be simplified by making the paper ejection roller interlock with the drive of the conveyor belt and ejecting the paper by rotating in the same direction as the moving direction of the belt. However, this configuration inevitably causes a drawback, namely, the fear that the document will be caught up in the paper ejection roller again due to the reversal of the paper ejection roller after paper ejection. This problem is solved by having a sensor that detects the presence or absence of a document and immediately stopping the device when a document is detected.

るようにしたことを特徴とする原稿搬送装置。A conveyor belt is brought into sliding contact with the document glass surface so that it can be driven in forward and reverse directions, and by forward rotation of the belt, the supplied document from one end of the belt is conveyed on the glass surface. The edge of the document is positioned on the specified glass surface, and after copying the document in this position, the belt is rotated in the normal direction again to transport the document to the other end of the belt on the paper ejection side. In a device that uses a roller to eject the paper to the outside, the ejection roller is interlocked with the belt so that the paper is ejected by rotating in the same direction as the moving direction of the conveyor belt, and the paper is ejected when the conveyor belt is reversely conveyed by this interlocking. In order to prevent the document once ejected from being re-engulfed by the reversal of the rollers, a sensor for detecting the presence or absence of the document is placed on the ejecting roller, and the sensor detects the document when the conveyor belt reverses. What is claimed is: 1. A document conveying device, characterized in that the device is stopped by a signal received by the user.
