<p>PROBLEM TO BE SOLVED: To make an input operation range large, to suppress the generation of an inertial force, and to improve the operability by moving an operation input means by an input means movement energizing means according to the position of an operation grip. SOLUTION: When the operation grip 21 moves by operator's operation out of a certain input range (range that does not exceed the movable range of the operation grip 21 of an operation input means 2) based upon the initial position of the operation grip 21 through a specific range control function, a new input range based upon the current position of the operation grip 21 is set and the moving operation of the operation input means 2 is controlled immediately by the input means movement energizing mechanism 4 so that the new input range is within the movable range of the operation grip 21 at the current position. At this time, operation control over driving motors 222, 232, and 242 of the operation input means 2 is so performed that the current position of the operation grip 21 does not change owing to the movement of the operation input means 2.</p> |
