記載の原稿リピート搬送装置。[Scope of Claim for Utility Model Registration] (1) In a document repeating device that rotates a document an arbitrary number of times within a conveyance loop, two pairs of rollers that convey the document, and a document disposed in series between the rollers, A first document detour section and a second document detour section are formed by upper and lower guide plates each having a convex surface and a concave surface curved with respect to the traveling direction and can be tilted up and down. A means for adjusting the inclination for changing the loop length is provided, and the amount of document skew that occurs in the first detour section is Sa The amount of document skew that occurs in the second detour section Sb The amount of document skew that occurs in the other transport sections Sc Amount of lateral deviation of the document that occurs in the first and second detour sections Ya Amount of lateral deviation of the document that occurs in other conveyance sections Yb Add the sign of the skew amount of the right leading skew and the lateral deviation of the right deviation, and A document characterized in that the left and right loop lengths of the first and second detour sections are changed so that when the signs of the skew amount and the lateral shift amount are negative in the opposite direction, -Sc=Sa+Sb, Ya=-Yb. Repeat conveyance device. (2) In addition to installing a document skew amount sensor and a lateral shift amount sensor in the document repeat conveyance loop,
Claim (1) wherein means for tilting the first and second detour parts are connected, and the tilting means is configured to adjust the tilting of the detour part based on the detected value of each sensor.
Document repeat transport device as described.
