PURPOSE: A device for inputting the angle of a looper is provided to measure the angle of a looper from different positions using a plurality of looper angle measuring devices and switch the inputs of the angle measuring devices, thereby reducing the loss caused by a failure of the looper angle measuring devices. CONSTITUTION: A device for inputting the angle of a looper comprises a plurality of looper angle measurers(10), a switching unit(20), and a key input unit(30). The looper angle measuring devices measure the angle of a looper from different positions. The switching unit is connected to one of the looper angle measuring devices and switched to output the measured looper angle. The key input unit selects the operation of the switching unit.
