Abstract: A marking apparatus is provided for use with a tape measure. The marking apparatus includes a marker support member attached to a first outer side of a tape measure housing, and the marker support member extends forward of the tape measure housing in the tape dispensing direction. A retractable marker unit is attached to the marker support member at a location distal to the tape measure housing. The retractable marker unit is located beside the measuring tape that is dispensed from the tape measure housing. The retractable marker unit includes a marker element for marking an article, based upon a particular indicia that is selected from tape measure indicia. A pointer member, for pointing to the selected indicia, is attached to the retractable marker unit and extends over a portion of the dispensed measuring tape. A magnifier unit can also be employed with the retractable marker unit. The retractable marker unit optionally may be operated to select a desired form of emplaced enhanced marking.
