Abstract
In an optical information reader for optically reading a target based on a light reflected from the target, a translucent optical member is located on an optical axis of an imaging lens and is rotatable around a rotation axis. The rotation axis is substantially orthogonal to the optical axis. The translucent optical member is fixable at least first and second predetermined positions. When the translucent optical member is fixed at the first predetermined position, the translucent optical member has a first thickness through which the optical axis is penetrated, and when the translucent optical member is temporally fixed at the second predetermined position, the translucent optical member has a second thickness through which the optical axis is penetrated. The first thickness and second thickness are different from each other.
