Sheet conveying apparatus, belt drive apparatus, image reading apparatus, and image forming apparatus |
摘要 |
A sheet conveying apparatus includes a conveying path for conveying a sheet, an optical displacement sensor that detects displacement of the sheet, and a calculating unit that calculates a movement index value indicating moving distances of the sheet in a conveying direction and a direction perpendicular thereto based on an output from the optical displacement sensor. The optical displacement sensor includes a plurality of light receiving elements arranged in a matrix array. A row alignment direction and a column alignment direction of the light receiving elements are tilted with respect to the conveying direction. |
