PROBLEM TO BE SOLVED: To provide an operator device which can generate a reaction force capable of obtaining a click feeling which is sufficiently large and good when an operator is operated.SOLUTION: A keyboard device A is provided with keys 11 rotating in a vertical direction through a key depressing operation with a support point O as a center, and reaction force generating members 25 and 26 for generating a reaction force against the keys 11 through a key depressing operation of the keys 11 which are arranged at positions different from each other. The reaction force generating members 25 and 26 are composed of members having such characteristics that the reaction force increases and reaches a peak and then decreases and are made to reach the peak at the same time at predetermined stroke positions of the keys 11. Thereby, a sufficiently large and good click feeling can be obtained when the depressing operation of the keys 11 is performed. |
