<p>PURPOSE: To provide a joy stick type controller having a simple constitution by decreasing constituent members, and easily assembled, reduced in cost, and improved in durability by reducing friction parts and can accurately return an operation rod to a neutral position. CONSTITUTION: A plate member having a spherical surface 12 which is connected successively to the operation rod 2 and has the same center with a spherical bearing 11 consists of springs 4 and 4 which automatically return the operation rod 2 to the neutral position with the expansion force based upon the slanting operation of the operation rod 2 and, a positioning mechanism 5 which positions the operation rod 2 at the neutral position by the relative movement between the plate member and spherical surface 12; and linear movement type potentiometers 6 and 6 are operated by the plate member so as to obtain a signal corresponding to the slanting operation of the operation rod 2.</p> |
