Title:
DISPLACEMENT DETECTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/088055
Kind Code:
A1
Abstract:
A compact detecting device capable of detecting a rotation angle and a linear
movement distance or both their operation speeds. The detecting device for
detecting the rotation angle and the linear movement distance of a movable member
that rotates and linearly moves or its rotation angle speed and linear movement
speed, wherein the movable member (30) comprises a first movable part (45) for
linearly moving together with the movable member (30) as it linearly moves as
above, a second movable part (34) for holding the first movable part (45) to rotate
freely and rotating together with the movable member (30) as the above movable
member (30) rotates, a first sensor (47) for outputting a signal according to
the linear movement of the first movable part (45) when it linearly moves, and
a second sensor (39) for outputting a signal according to the rotation of the second
movable part (34) when it rotates.
