Abstract
A reading device including a position reference member having a reference pattern having a line extending along a first direction of the position reference member, the position reference member movable in a second direction orthogonal to the first direction; a reader including a plurality of sensor chips arranged along the first direction, each of the sensor chips having a length defined by a plurality of pixels; and circuitry. The circuitry is configured to detect the reference pattern of the position reference member using the reader; determine coordinates of at least two sensor chips in the second direction, based on the detected reference pattern of the position reference member; and correct a position of a reading target in the second direction based on the coordinates determined for the at least two sensor chips of the reader in the second direction.
