MANUFACTURING METHOD FOR SCALE FOR DETECTING CONVEYANCE ANGLE OF CONVEYANCE ROLLER, AND RECORDING DEVICE

PROBLEM TO BE SOLVED: To detect conveyance angle with high accuracy by a method, where the tolerance of the component of an encoder used for a conveyance roller or the eccentricity or the like of the encoder in its assembly is canceled. SOLUTION: The conveyance outer periphery face part of the conve...

Summary:PROBLEM TO BE SOLVED: To detect conveyance angle with high accuracy by a method, where the tolerance of the component of an encoder used for a conveyance roller or the eccentricity or the like of the encoder in its assembly is canceled. SOLUTION: The conveyance outer periphery face part of the conveyance roller 2b is chucked (pinched) by a chuck 26. The conveyance roller 2b is made to turn by a motor 27. Its rotation angle is detected by a reference encoder 28. On the basis of the output of the reference encoder, the rotation angle is allocated, the direction of the current of a magnetization head 30 is changed, and N-poles and S-poles are magnetized.
