ABSTRACT:
In an exemplary embodiment, a hand held bar code reader has a handle portion and a reader head portion which may be held spaced from a bar code data carrier during a reading operation. Light energy is directed outwardly through a window so as to illuminate a bar code sensing region in front of the window having a depth dimension of at least about ten millimeters, and an optical system focuses bar code patterns in the sensing region onto an image photosensor in the reader unit with a resolution so as to read e.g. bar code formats with a minimum bar or space width of about 0.0075 inch or less. The bar code image is converged through a generally rectangular optical aperture and is reflected onto the image photosensor by a reflecting mirror positioned relative to the image photosensor by virtue of their common association with a printed circuit board.
