Abstract
In a sight scope, an erect sleeve received in a scope body is inclined with respect to the axis of the scope body by an inclination adjusting mechanism. A movable sleeve capable of moving axially of the erect sleeve is disposed within the erect sleeve, and an erect lens system is supported by this movable sleeve. A position adjusting mechanism for moving the movable sleeve axially of the scope body includes a rotary member. This rotary member is allowed to extend all the way through the scope body and supported for turning about an axis extending radially of the scope body. The rotary member has a control handle formed on an external end of the rotary member and a cam member disposed on an internal end of it. A follower is received in the scope body. This follower is moved axially of the scope body in accordance with rotation of the cam member. The movement of this follower is transmitted to the movable sleeve through an association sleeve which is fitted to the outer periphery of the erect sleeve.
