IPC: G01D5/36
Filed: 2002-04-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide an encoder capable of accurately detecting rotation even if a shaft, an object of rotation detection, is slightly moved by variations in the tension of an endless belt extended over the shaft, the object of rotation detection.  <P>SOLUTION: A disk-shaped scale 31 is mounted to a shaft end of a transfer driving roller 17a, and a photointerruptor 34 detects the rotation of the disk- shaped scale 31. The transfer driving roller 17a is slightly moved in the directions along a rectilinear line connecting the centers of a pinion gear 41 and a gear 46 as the tension of the endless belt 42 varies. The photointerruptor 34 is arranged approximately in the extended line of the rectilinear line connecting the centers of the pinion gear 41 and the gear 46. Consequently, it is possible to appropriately detect the rotation of the disk-shaped scale 31 without detecting changes in the state of the disk-shaped scale 31 even if the transfer driving roller 17a is slightly moved.  <P>COPYRIGHT: (C)2004,JPO
