A bar code scanner housing assembly for enclosing the components of a bar code scanner is provided. The bar code scanner housing assembly comprises a cartridge including an upper window which is removably mounted therein and a housing including a recess for receiving the cartridge, a lower window mounted within the recess and means for generating bar code scan lines. The cartridge is removably mounted within the recess such that the surface of the cartridge is substantially flush with the upper surface of the housing. The housing assembly may include a mask molded into the recess so as to minimize the amount of ambient light passing into the housing. The housing assembly may also comprise a groove surrounding the lower window which has a removable gasket disposed therein for sealing the space between the upper window and lower window. The housing assembly may comprise a window cartridge which eliminates the need for a separate upper window disposed within the cartridge of a bar code scanner housing assembly.
