<p>PURPOSE: To provide a hair processing device, making possible to control the torque of a motor shaft at a predetermined safe value by using a simple method, by composing so that a current used by the motor is introduced through a current controlling circuit equipped with a switching device for controlling the current at a predetermined value. CONSTITUTION: In each communicator position, the current of flowing through a motor 7 is flowed through a current controlling circuit 29, thus the current is maintained at a predetermined value. The current controlling circuit 29 has two steps, i.e., an actionable step 30 and a safety step 31. An actual step for carrying out the current control is performed by the actionable step 30, however if this step is broken off, the role of controlling the current is played by the safety step 31. The actionable step 30 has a current controlling circuit element 32. The setting of a current value, i.e., a current from input to output is controlled at a set value, is carried out for the actionable step 30 by a double potentiometer 33 mechanically connected to a control connecting portion 32'. A control voltage for determining a controlled current value against the actionable step 30 and the safety step 31 is set into various setting values through a resistances 35, 36.</p> |
