Abstract
A level including a sensor that detects a tilt angle; a display unit including a plurality of strip-shaped display members that linearly emits light by an LED to display the tilt angle; and a controller that receives an output signal from the sensor and outputs a control signal so that a specific strip-shaped display member glows. The strip-shaped display members include one horizontal strip-shaped display member positioned at a middle of the display unit and a plurality of strip-shaped display members for tilt-angle display that has tips bent toward a center of the display unit. LEDs are attached to ends of the strip-shaped display members, respectively, and a pair of strip-shaped display members which is point-symmetrical with respect to the center of the display unit simultaneously glows according to the tilt angle.

A level comprising:
- a sensor that detects a tilt angle;
- a display unit including a plurality of strip-shaped display members that emits light linearly by an LED and displays the tilt angle;
- and
- a control circuit that receives a signal from the sensor and outputs a control signal so that a specific strip-shaped display member glows,
- wherein the strip-shaped display members include one horizontal strip-shaped display member positioned at a middle of the display unit and a plurality of strip-shaped display members for tilt-angle display that has tips bent toward a center of the display unit, wherein each of the strip-shaped display members has an LED attached to an end, and a pair of strip-shaped display members provided to be point-symmetrical with respect to the center of the display unit simultaneously glows according to the tilt angle.
