Abstract

A microscope with an automatic sweeping device which automatically sweeps a preparation, membrane filter, etc. for observing subjects, such as cells, microbes or others, existing thereon, is offered. The automatic sweeping device has the following functions: a control mechanism drives a transfer mechanism for moving a holder containing subjects according to the instructions from a control console to perform automatic sweeping by stepped or continuous movement of the holder, and at the base time a printer, memory and display are so controlled that they respectively print, store and display position and other various data. Manual operation is also possible immediately after suspension of automatic operation. Positions of subjects detected by a position detector are stored in the memory. Whenever automatic operation is restarted, the holder returns to the position where the suspension occurred, to resume sweeping operation and moves directly to a particular memorized position when a memory number is keyed in from the control console, and to a position at particular coordinates when coordinates of a position other than the memorized position are inputted from the control console.
