    摘要： A scale indication device includes a character plate (30) having sets of characters printed on a front side thereof such that each set of characters has characters disposed about an eccentric circle having a predetermined radius. A scale plate (40) is disposed adjacent the character plate. The scale plate (40) has a window (43) corresponding to each of the sets of characters such that only one of the characters in each set may be viewed through the window at a time. An eccentric rotation device (20) is mounted on a gearbox (10) and rotates the character plate such that different ones of the characters in each set may be viewed through the window (43). The rotation device includes a scale switching gear (23) rotatable about an axis, a first engagement device (24) formed on the scale switching gear at a distance from the axis equal to the predetermined radius, and a second engagement device formed on the character plate (30) for rotatably engaging the first engagement device (24).
