Abstract
The rotation angles around the X and Y axes due to the operation of a joystick lever having degrees of freedom of three axes are respectively detected by two rotation angle detectors. A push button switch is provided at the edge of the joystick lever. When the push button switch is not operated, the operating direction and operation amount of the joystick lever are calculated on the basis of the outputs of two rotation angle detectors. When the push button switch was operated, the operating direction and operation amount of the joystick lever are calculated from the output of either one of two rotation angle detectors.
Claims5
A joystick ship steering apparatus for use in steering of a ship equipped with a propelling equipment for generating a thrust in the back and forth directions, a rudder for changing the direction of the thrust of said propelling equipment, and a propelling equipment for generating a thrust in the lateral direction, said apparatus comprising:
- a joystick unit having a joystick lever which can be freely operated around three X, Y, and Z axes;
- first rotation angle detecting means for detecting an angle of rotation around the X axis by said joystick lever;
- second rotation angle detecting means for detecting an angle of rotation around the Y axis by the joystick lever;
- a push button switch provided at the edge of the joystick lever;
- and
- arithmetic operating means for calculating the operating direction and an amount of operation of the joystick lever from detection outputs of said first and second rotation angle detecting means when said push button switch is not operated, and for calculating the operating direction and the amount of operation of the joystick lever from the detection output of either one of said first and second rotation angle detecting means when said push button switch was operated.
