Abstract
A move-in-company style joy stick comprising in a knob thereof a space of suitable size formed by a partition plate, a ball added with a weight, a horizontal grating and a vertical grating are placed in the space. The horizontal and vertical gratings are provided each with a coaxial roller respectively contact the ball in rotation at a position slightly lower than a horizontal central line of the ball. A supporting wheel is provided at a position having an equal angular distance to both the coaxial rollers. When the knob of the joy stick is shaken, a vertical central line of the ball added with the weight is always kept in its vertical position, hence the coaxial rollers are rubbed by the ball in rotation. In this way, the required amount of displacement of the horizontal and vertical gratings being shaken is obtained.
