Patent ID: 7308845

Claim:
A sawing angle reading-and-indicating device for a table sawing machine comprising a saw base and a driving connecting rod, said driving connecting rod turned to actuate a worm to rotate, said worm on said driving connecting rod rotated to actuate a sector gear on said saw base to rotate, said sector gear actuating said saw base to shift bias for an angle within a preset range; and, Characterized by an angle sensing device composed of an angular signal reading head and a circuit device, said angular signal reading head fitted on an inner end of said driving connecting rod, said angular signal reading head actuated to rotate together with said driving connecting rod and produce an advancing or retreating signal and put it out to said circuit device, said circuit device composed of a microchip unit, a digital indicator and a set switch, said signal produced by said angular signal reading head being put in said micro-chip unit and converted into an angular value of said saw base, said angular value of said saw base indicated on said digital indicator, said set switch functioning to reset and re-correct a proportional value between said signal output by said angular signal reading head and the angle of said saw base.
