摘要：The invention provides a tilt detecting device, in which a fixed member and atilting plate are relatively rotatably provided via a pivot member, either one of the fixedmember or the tilting plate is integral with the pivot member, comprising a tilt detecting
unit provided on either of the fixed member or the tilting plate which relatively rotateswith respect to the pivot member, and an angle detection pattern formed on the pivotmember, wherein the tilt detecting unit comprises a light source for projecting anillumination light to the pivot member, a photodetection element for receiving theillumination light reflected by the pivot member, an optical system for projecting apattern image to the photodetection element and an arithmetic unit for detecting arotation of the pivot member based on a projecting position of the pattern imageprojected onto the photodetection element when the pivot member rotates.
