Claim Text:
1. An image reading apparatus comprising: a reading unit having a plurality of photoelectric conversion elements arranged in a main scanning direction, each of the plurality of photoelectric conversion elements being configured to generate an electric signal in response to receiving light from an reading object; a white reference plate arranged to face the reading unit; a motor configured to move at least one of an original and the reading unit relative to each other; and a controller configured to: wherein in a case of reading the image of the original by the reading unit, the controller is configured to: in a case of obtaining the white reference data, the controller is configured to: provide the second transfer timing signal to the reading unit such that a second electric signal generated by the photoelectric conversion elements is transferred in synchronization with the second transfer timing signal, wherein in the case of reading the image of the original by the reading unit, the controller is configured to drive the motor at a constant driving velocity; and in the case of obtaining the white reference data, the controller is configured to provide the second transfer timing to the reading unit such that the second electric signal is transferred at a constant time interval corresponding to the constant driving velocity of the motor.
