A code reader includes an illumination section, an imaging unit having a Scheimpflug optical system, a control unit that executes decoding processing on the code attached to a workpiece based on an image output from the imaging unit, and a housing that stores the illumination section, the imaging unit, and the control unit and has a light receiving window. The light receiving window is provided on the first side surface of the housing, and has a short side extending in a lateral direction and a long side, longer than the short side, extending in a longitudinal direction. A plane formed by the light receiving window intersects a plane formed by the focal plane of the Scheimpflug optical system. The illumination section is disposed adjacent to the light receiving window in the lateral direction of the light receiving window.
