Claims

[Scope of Utility Model Registration Claim] (1) Copying a large number of copies from a single original, which has a means for feeding the original one by one and a means for repeatedly feeding the fed original into an exposure path through a circulation path. In a copying machine for copying documents, a first device is installed in the circulation path of the document to position the leading edge of the document in a normal position.
a correction means, a document detection means provided in the circulation path to detect deviation of the document, a member forming a document reversal path in the circulation path, and one end and the other end of this member, respectively. a second correction means for correcting the misalignment of the original by changing the length of the circulation path of the portion of the original passing through; the second correction means acts independently on both ends of the member;
One of the biasing means is actuated to bias one end of the member relative to the other end when the original detecting means detects a deviation of the original. Automatic document position correction device. (2) Practical use characterized in that the means for feeding the original one sheet at a time also feeds photosensitive paper in synchronization with the original, superimposes the fed original and the photosensitive paper, and sends the fed original to an exposure section for copy printing. An automatic document position correction device according to claim 1 of the patent registration claim. (3) The automatic document position correcting device according to claim 2, wherein the member forming the document reversing path is a printing cylinder. (4) Claims 1 to 4 of the claims for registration of a utility model, characterized in that the document detection means includes detection means arranged on both sides of a reference position of one side edge of the document in the direction of travel of the document. 3. The automatic document position correction device according to item 3.
