Abstract:
1. A sheet conveying apparatus comprising: a conveying path that conveys a sheet-like member; an optical displacement sensor that detects displacement of the sheet-like member based on a result obtained by detecting a light emitted from a light emitting element and reflected on a surface of the sheet-like member in the conveying path using a plurality of light receiving elements arranged in a matrix array; and a calculating unit that calculates a movement index value indicating moving distances of the sheet-like member in a conveying direction and in a direction perpendicular to the conveying direction based on an output from the optical displacement sensor, wherein the optical displacement sensor is provided in such a manner that a row alignment direction and a column alignment direction of the light receiving elements in the matrix array are tilted by 45 degrees with respect to the conveying direction.
