Title:
SPATIAL COORDINATE DETECTING DEVICE
Document Type and Number:
Japanese Patent JP3416291
Kind Code:
B2
Abstract:
PURPOSE: To detect not only the relative tilt angles and rotational angles of both a light emission part and a detection part to the axis connecting them, but also the relative distances of both the parts in a Z-axial direction and a Y-axial direction with high precision through simple structure.
CONSTITUTION: The detection part is arranged at an operation member which is manually operated by an operator. At the light emission part 10, two light sources 12 and 13 which emit mutually distinctive lights are arranged at a specific interval, and the detection part 11 is provided with two stop openings 15a and 15b which are arrayed at a specific interval in the Y-axial direction when a Z axis extending to before the detection part 1 and X-Y orthogonal coordinates crossing it at right angles are set, and 1st and 2nd light receiving elements 17 and 18 which face each other. The 1st light receiving element 17 has two light reception parts which are divided in the Y-axial direction, and they are irradiated with different spot lights. The 2nd light receiving element 18 has four light reception parts which are divided in the X-axial and Y-axial directions, and they are irradiated with different spot lights.
