Drill level indicator

摘要

A power tool (10) includes a levelling device (30) which includes a rotatable member (40) which seeks an equilibrium position which corresponds to a level position. A rotating device includes a member which enables passage of a beam. An electrical circuit which includes an emitting device (50), a receiving device (52) and an indicating device is electrically coupled such that upon activation, the emitting device (50) emits a beam which passes through the beam passing member. The beam is received by the receiving device (52) which, in turn, activates the indicator device (54). The indicator (54) is generally a light emitting device which has a varying brightness so that the user may view the indicator (54) from all sides of the power tool (10). <IMAGE>
