PROBLEM TO BE SOLVED: To provide the tactile force controller of an operator with high practicality capable of simplifying a structure, being miniaturized and lowering a cost. SOLUTION: By braking the turning of a key 10 by an electromagnetic actuator 20, reactive force is supplied to the key 10 and a touch feeling is generated. In the meantime, the position information of the key 10 detected in a position sensor 46 is supplied to a memory and what degree the reactive force of the key 10 present at the positron is to be is decided based on a touch table inside the memory. When a driving current is supplied from a driving circuit to the solenoid coil 21 of the electromagnetic actuator 20 so as to supply braking force matched with the reactive force to the key 10, the rotor part 13 of the key 10 is attracted to and brought into press-contact with an excited stator yoke 21, the key 10 is braked and thus, the touch feeling corresponding to the position of the key 10 is continuously obtained. |
