    摘要： A locking system for a tape measure includes a locking pad located inside the case in which the coiled tape measure is contained. As the tape is dispensed from its case, the locking pad locks the tape against the inside of the housing. When it is desired to unlock the tape, a force from the side of the tape housing causes the locking pad to lift out of its position in contact with the tape. The tape is then recoiled into the housing.
