Abstract
PURPOSE: To obtain accurately the linear distance and the bearing from a start point or the linear distance and the bearing to a destination by detecting the rotation bearing acoompanied with the movement of a rotary object equipped with a magnetic needle by a photo sensor and performing operation for every unit distance movement.
CONSTITUTION: Transparent disc-shaped rotary object 1 is provided freely rotatably where a magnetic needle is fixed in the diameter direction, and pattern 2 where bright and dark parts are arranged at an equal interval in the circumference direction is formed on the surface of rotary object 1. Two pairs of luminous materials and photo sensors 9, 10, 6, and 7 are arranged while interposing pattern 2 of rotary object 1. Further, a distance meter which generates one pulse for every unit distance movement is provided. in this constitution, the rotation bearing of rotary object 1 is detected by light receiving or non-receiving of photo sensors 6 and 7, and the unit ditance and the ratation bearing are used for every unit distance movement to obtain the moving direction and the linear distance.
