Abstract: A tape measurer includes a housing, a flexible measuring tape rule received in the housing in a coiled position, and a device including an integrated circuit or a processing unit for recording and displaying purposes. The measured data may be easily and quickly recorded in the recording circuit or the integrated circuit or in the processing unit and may be displayed after all the required data have been measured and recorded, such that the measuring operations may thus be quickly conducted or proceeded. A laser device may generate a laser beam to indicate far away points.

Abstract: An indicator has two radiation sources supported in a housing and directed to two perpendicular directions to generate two light beams and to indicate a right angle. A semi-transparent mirror is engaged in the housing, the light beam generated by one radiation source has a portion transmitted through the mirror and another portion reflected by the mirror to indicate another right angle, and to indicate two opposite points far spaced from each other. A cover has three windows aligned with the light beams for allowing the light beams to be transmitted out of said cover.
