Japanese Patent JP4166306

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To facilitate assembly regulation for accurate positioning of respective objective lenses to an optical axis, to prevent influence of the change over aging in an objective lens mounting condition or a revolver, to stabilize vibration in a switching/stopping time, and to surely operate a switch action quickly. SOLUTION: In an objective lens switch device by which each of a plurality of objective lenses is positioned selectively to the optical axis of an optical device, a turret turning position is detected whether it is within an engagement range based on a plate spring and a click ball or not by means of an engagement sensor 74. The angle displacement of the turret is detected by an angle sensor 75. On the basis of the signal detected by the angle sensor 75, a CPU 72 performs control to keep the revolution speed of the turret constant within a specific range.
