Abstract

An imaging assembly having a 2D image sensor so oriented in relation to its supporting structure that, when a reader including the imaging assembly is held in its normal operating position during the reading of a 1D bar code symbol, the image of that 1D symbol is aligned with a diagonal of the image sensor, thereby increasing the resolution with which the 1D symbol is read. An image sensor including a generally rectangular 2D array of photosensitive elements is secured to a mounting structure so that the plane of the array is generally parallel to and approximately in the focal plane of an associated 2D imaging optics assembly. The angular orientation of the image sensor with respect to its mounting structure is selected so that, when a reader including the imaging assembly is held in its normal reading position during the reading of a 1D symbol, the image of the 1D symbol is formed along a diagonal of the array.
