An apparatus is configured to employ with a retractable tape measure including a flexible measuring tape. The apparatus includes an electronic system including a laser receiver and a body configured to house the electronic system therein. The laser receiver is configured to detect a laser projected in at least one of a red wavelength and a green wavelength. The body includes an arcuate-shaped cavity configured to receive the flexible measuring tape in a sliding engagement, and a top surface oriented to face in a direction from which the flexible measuring tape is read with the flexible measuring tape received in the cavity. The top surface includes a port configured to align with the laser receiver.

The present invention relates to a distance measuring device, which includes a shell and a laser ranging device provided at the inside and/or the outer surface of the shell. The advantages of the invention lie in that a distance measuring device is provided, which combines the tapeline with the laser ranging device, possessing both short distance measuring and long distance measuring functions, and has such features as simple operation, convenience for carrying, lower cost, high measuring accuracy, etc., being suitable to be widely used in applications such as in the fields of construction work, interior decoration, measurement in danger zone, etc.

A combined square leveling for combing multiple construction tools into a single device includes a framer's square for measuring angles during construction. A tape measure is retractably positioned within the framer's square and the tape measure is urgeable outwardly from the framer's square for measuring distance. The tape measure is biased to retract into the framer's square. A bubble level is coupled to the framer's square to determine if a surface is level. A laser level is slidably coupled to the framer's square to emit a beam of light to establish a reference point on a distal object.
