PURPOSE: A noncontact type length measuring device is provided to reduce an error range of a measurement value as the width, length, and the height of a material transferred by a transfer unit are measured respectively by sensors of first, second, and third measuring units. CONSTITUTION: A noncontact type length measuring device comprises a transfer unit, a first measuring unit(20), a second measuring unit(30), a third measuring unit(40), a control unit(50), and a monitor(60). A material is seated in the transfer unit and transferred in one direction by the same. The first measuring unit measures the width of the material transferred by the transfer unit and transmits the measurement value. The second measuring unit measures the height of the material and transmits the measurement value. The third measuring unit measures the length of the material and transmits the measurement value. The control unit controls the transfer unit, the first, second, and the third measuring units and receives the measurement values measured by the measuring units. The monitor outputs the measurement values received from the control unit with images. |
