Abstract:
1. A slide operation-type dovetail groove sliding stage for performing positional adjustment of a precision apparatus by fitting a trapezoidally-projecting dovetail into a trapezoidally-recessed dovetail groove to slide a sliding component with respect to a fixed component, and performing an operation of sliding the sliding component with a driving means, characterized in that: the slide operation-type dovetail groove sliding stage comprises a sliding lock screw for locking sliding of the sliding component by causing the screw to abut on an inverted triangle-shaped protrusion, provided on a sidewall of the sliding component approximately parallel to a sliding direction and coupled to the sliding component, to bring the protrusion into contact with a dovetail of the fixed component, and by tightening the screw; the sliding lock screw is used as a sliding adjustment screw for performing fine adjustment of a degree of sliding of the sliding component with respect to the fixed component by adjusting an amount of rotation of the screw abutting on the inverted triangle-shaped protrusion to bring it into contact with the dovetail of the sliding component, and a force application rod which an operator grasps to perform an operation of sliding the sliding component to a desired position; and the slide operation-type dovetail groove sliding stage further comprises a reaction force rod which is removably attached to the fixed component and takes reaction force with other fingers of the operator when he/she performs the operation of sliding the sliding component to a desired position, with the force application rod.
