Abstract
An apparatus for detecting a rotation operation of revolver is provided with a rotation direction detecting device for detecting a rotation direction of revolver by detecting a displacement of a position indication portion indicating a position of objective mount portion. In case that the rotation of revolver is carried out either in a manual manner or in an automatic manner, an address of mount hole in revolver which is to be next located at the predetermined position may be determined at start of rotation operation of revolver.

An objective replacing apparatus comprising:
- objective replacing means having a plurality of objective mount portions and selectively positioning at a predetermined position a desired objective out of a plurality of objectives set in said mount portions;
- a position indication portion for indicating respective positions of said plurality of mount portions, said position indication portion being disposed on said objective replacing means as to be formed corresponding to said respective mount portions;
- an address indication portion indicating respective addresses of said plurality of mount portions, said address indication portion being disposed on said objective replacing means as to be formed corresponding to said respective mount portions;
- means for detecting, when said desired objective is located at said predetermined position, an address of a mount portion in which the desired objective is set, from said address indication portion;
- means for detecting a displacement of said position indication portion after said desired objective is located at said predetermined position thereby to detect a movement direction of said objective replacing means;
- and
- means for determining an address of another desired mount portion which is to be next located at said predetermined position, based on the address of said desired mount portion from said address detecting means and on the movement direction of said objective replacing means from said movement direction detecting means.

A microscope comprising:
- objective replacing means having a plurality of objective mount portions and selectively positioning at a predetermined position a desired objective out of a plurality of objectives set in said mount portions;
- a position indication portion for indicating respective positions of said plurality of mount portions, said position indication portion being disposed on said objective replacing means as to be formed corresponding to said respective mount portions;
- an address indication portion indicating respective addresses of said plurality of mount portions, said address indication portion being disposed on said objective replacing means as to be formed corresponding to said respective mount portions;
- means for detecting, when said desired objective is located at said predetermined position, an address of a mount portion in which the desired objective is set, from said address indication portion;
- means for detecting a displacement of said position indication portion after said desired objective is located at said predetermined position thereby to detect a movement direction of said objective replacing means;
- a memory for storing information of the objectives set in the respective mount portions;
- means for determining an objective set in another desired mount portion which is to be next located at the predetermined position, based on the address of said desired mount portion from said address detecting means, the movement direction of said objective replacing means from said movement direction detecting means, and the information of objectives from said memory;
- and
- means for controlling a part of the microscope other than the objectives, based on the objective determined by said determining means.
