Abstract

PURPOSE: To secure a stable operation and to enable to recognize a feed speed as response at handling by a method wherein a reactional force while is increased in accordance with an increase of an operation amount of a handle is applied to the handle.
CONSTITUTION: A ball 13 is connected to a lever 12 with a handle 11 and the ball 13 is provided with a pin 17 pressed by a spring 16. When the lever 12 is inclined, a reactional force is applied by the spring 16 and the pin 17 in accordance with an inclined angle and when a hand is released, the lever is returned to a neutral position. Two pieces of pins 19 are protrudingly provided on the ball 13 symmetrically and when the lever 12 is inclined, the pin 19 pushes down one of a plunger 20, a pressure transducer 21 is operated through a spring 23 and another plunger 22 to transduce it into a signal of an electric resistance and controls a feed speed of the machine. The reactional force may be set by changing dimensions and elastic coefficients of respective members within a force transmitting route from the handle 11 to the pressure transducer 21.
