In the moving angle detection device, a plurality of pattern lines arranged side by side are disposed on the encoder board in a circumferential direction, and a plurality of contact pieces are provided corresponding to the pattern lines. Characteristic rotation angle detection device.

Claims

[Claims for Utility Model Registration] An encoder that has a plurality of pattern lines and is disposed on either a rotating ring that rotates around the imaging optical axis or a fixed member that is fixed around at least the imaging optical axis. a substrate; and a contact piece that contacts the pattern line of the encoder substrate and is disposed on the other side of the rotation ring or the fixed member. In a rotation angle detection device in a lens barrel that detects as a signal, a plurality of the pattern lines are divided and arranged on the encoder substrate, and at least two encoder substrates are provided around the optical axis, and
A rotation angle detection device for a lens barrel, characterized in that a plurality of the contact pieces are provided corresponding to the pattern lines, and the widths of the encoder substrate and the contact pieces in the optical axis direction are sandwiched therebetween.
