PURPOSE:To enable the titled detector simultaneously three dimensionally to detect a desired position and direction unrestrictedly, by detecting the vertical displacement of the external force added to a contact piece integrated with a detection rod with a supporting arm and a displacement detector and the displacement at right angles with the center of axis with a grooved arm and a rotary displacement detector. CONSTITUTION:Because the detection rod 4 integrated with a contact piece 1 is rotated via the grooved part of grooved arms 16a and 16b in the direction rectangular to the center of axis by making a ball bearing 2 as a fulcrum when the contact piece 1 is added to with an external force, the rotary axes of rotary potentiometers 11a and 11b connected thereto are rotated and their ohmic values change. On the other hand, the supporting arms 18a and 18b of detection rod are moved connectingly to the vertical motion according to the external force of detection rod 4 via a guide 20, a slide type potentiometer 22 moving vertically too, and its ohmic value changes. Further, the neutral point reset of detection rod 4 after removing the external force, is achieved with the spring force of the supporting arm extension springs 19a and 19b and of the arm extension spring 15b. Thus, the desired position and direction can three dimensionally simultaneously be detected according to the change of ohmic values. |
