Abstract:
1. A digital miter saw comprising: a base having a workpiece placement surface for positioning a workpiece thereon; a fence fixed to the base and having a contact surface to which the workpiece is forced; a circular saw portion for rotatably supporting a circular saw blade; a supporting member for pivotably supporting the circular saw portion about a pivot shaft extending substantially parallel to an axial direction of the circular saw blade; a turntable connected to the supporting member, and having an upper surface cooperating with the workpiece placement surface of the base to support the workpiece, the turntable being capable of rotating about a rotating axis with respect to the base, thereby changing an angle between the contact surface of the fence and the circular saw blade; rotation angle detection means provided on a portion adjacent to a rotation axis of the turntable and contacted to both the turntable and the base, and provided below the workpiece placement surface, for detecting a rotation angle of the turntable with respect to the base to output an electrical signal indicating the rotation angle; digital display means for digitally displaying the rotation angle, the digital display means being provided below the workpiece placement surface so as not to protrude above the workpiece placement surface of the base; and control means for generating an electrical signal for displaying the rotation angle on the display means based on the output signal of the rotation angle detection means, wherein the digital display means is provided on the turntable, and wherein the turntable includes an operating handle protruding outward, and the digital display means is provided between the operating handle and the rotation axis of the turntable.
