PROBLEM TO BE SOLVED: To easily, quickly and accurately measure the length from an imaginary intersection point on prolonged lines of both pieces in sheet metal to end parts of the respective pieces. SOLUTION: In the digital calipers of the present invention, a turning member 3 turned to conform a main scale 1 with a vertical face using a shaft 4 as the center is attached to a base end 1a of the main scale 1. The turning member 3 has a pair of front and rear parallel pieces 3a arranged with a clearance C for engaging the the main scale 1. In the parallel pieces 3a, a face 3a1 in a side corresponding to an under face 1b of the main scale 1 is formed in the same height over a longitudinal direction. A jaw 6 is formed bar-likely along the under face 1b of the main scale 1, while directing a tip 6a toward a side of the base end 1a. Both end positions 6b on the tip 6a side of the jaw 6 are formed into a ascending slope shape toward the side of the base end 1a. The tips 6a on both side positions 6b abutting on the faces 3a1 of the parallel pieces 3a are formed into a sharpened shape. A tip face 6c1 of a portion 6c located between both side positions 6b and within a thickness of the main scale 1 is formed into a vertical face. COPYRIGHT: (C)2004,JPO
