Abstract
Abstract In a typing error correction system, typing error correction fluid is sprayed from an aerosol spray assembly through an aperture in a mask and onto a typing error. The mask comprises a portion of a spray discharge assembly that receives and supports the aerosol spray assembly. A discharge head mounted in the spray discharge assembly actuates the aerosol spray assembly upon movement of the aerosol spray assembly into the spray discharge assembly, and includes a normally sealed spray discharge passageway which is opened to permit discharge of the spray. A reticular foam collar mounted in the spray discharge assembly absorbs spurious spray, and a viewing port formed through the spray discharge assembly facilitates alignment of the aperture in the mask with a typing error.
