Title:
ALL DIRECTION DISTANCE DETECTOR
Document Type and Number:
Japanese Patent JP2000162318
Kind Code:
A
Abstract:

To provide an all direction distance detector capable of accurately detecting a distance at 360 degrees.

A driving region R1 of a region for installing all a light emitting unit 2, a light receiving unit 3 and a signal processor 5 is provided at one side of an optical region R2 having a light emitting region R2a and a light receiving region R2b. Thus, signal lines or the like between the regions R2a and R2b do not pass through the region R2 to provide an all direction distance detector capable of completely detecting all direction distances at 360 degrees. Thus, since a distance of wirings is shortened, an influence of an electric noise to a light receiving signal or the like caused by a driving system or the like of a rotating mechanism is suppressed, thereby improving an accuracy of detecting the distance.
