Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a copying machine configured to be able to make copies using continuous paper, and in particular to a copying machine configured to be able to make copies using continuous paper. The present invention relates to a document feeder configured to automatically feed the continuous paper in a copying machine configured to be able to obtain copies at any time.

(Prior Art) Conventionally, when copying is performed using computer output paper on which printing is performed in a continuous state, for example, when each document can be separated, copies are cut out one by one and placed on a platen glass one after another.

On the other hand, if you need to preserve a piece of computer output paper that remains continuous,
Copying is performed by setting the image planes of continuous originals one after another on a platen glass.

In addition, in the case of a copying machine equipped with an automatic document feeder exclusively for computer output paper,
By simply setting a continuous document on the automatic document feeder, continuous document feeding and copying operations can be easily performed.

(Problems to be Solved by the Invention) However, in the conventional apparatus as described above, for example, when copying is performed by cutting off computer output paper, it takes a lot of effort to prepare for copying. This requires a heavy burden on the operator, and in the case of a system in which the image planes of continuous documents are set one after another on the platen glass, there are drawbacks such as a tendency for image positions to shift.

Therefore, if a shift occurs in the image position, the image surface of the copy will become non-uniform, resulting in a copy that is extremely difficult to read, and the value of the copy will decrease.

On the other hand, when copying is performed using an automatic document feeder specifically designed for computer output paper, the burden on the operator is reduced and copying efficiency is improved. The automatic document feeder is relatively expensive, and when the automatic document feeder is installed in a copying machine, it has the disadvantage that it cannot copy normal documents.

In addition, even if the amount of copies made using computer output paper is small compared to the amount of normal copies, it is necessary to prepare a dedicated automatic document feeder, which increases the total cost of the copying machine. There are disadvantages such as an increase in

(Purpose of the invention) The present invention is intended to eliminate the drawbacks of the conventionally used devices as described above, by configuring a tractor assembly with a simple mechanism so that it can be attached to a copying machine. It is an object of the present invention to provide a device that allows a computer output sheet to be easily copied and a copy to be obtained even when a normal copying machine is used.
