ABSTRACT:
A tape measure includes an enclosure including an upper unit and a lower unit each defining a notch communicating with each other. The upper unit forms a protrusion. Poles are respectively formed on the upper unit and the lower unit adjacent the notches. The upper unit forms a pair of latches on opposite sides of the notch. The lower unit forms a pair of pivots on opposite sides of the pole. A springloaded tape cartridge is accommodated in the enclosure and includes a wheel, a gasket, and a gear. The first and second elastic members are respectively rotatably attached to the pivots of the lower unit. One end of each elastic member engages with the gear. The button is disposed at the notches of the enclosure. A pair of projections is formed on the button and presses opposite ends of the first and second elastic members respectively.
