Claims

[Scope of utility model registration request]

A main shaft 10 is rotatably supported on a support base 4 that can freely move parallel to the drawing surface in any direction, a scale mounting plate 14 is fixed to the main shaft 10, and encoder boards 22, 34 are attached to the support base 4. In the device in which the main shaft 10 and the member 1 are interlocked with each other,
A detection body 2 in which sensors 24 and 36 are provided at 2 and 42 to face the outer periphery of the encoder disks 22 and 34.
8 and 38 are attached movably in the direction of the diameter extension axis of the encoder disks 22 and 34, and
8, 38 are pressed toward the center of the encoder plates 22, 34. A scale angle detection device for a universal parallel ruler.
