DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a microscope with an automatic sweeping device which automatically sweeps a preparation, membrance filter, etc. for observing subjects, such as cells, microbes or others, existing thereon.
BACKGROUND ART
The applicant has proposed a microscope with an automatic sweeping device of the kind set forth in Japanese Utility Model Application Nos. 182909/'83 and 53319/'84.
The device is constructed so that the whole area or desired regions are automatically and successively swept by each observation division, or intermittently swept at any predetermined pitch, sweeping being able to be stopped for any observation period at any location and thereafter restarted, thereby permitting the whole area or desired region to be observed perfectly and easily.
However, the microscopes with automatic sweeping devices of the prior art have a disadvantage in that a preparation, etc. must be moved using a switch on a control console for observing a particular area, the operation being correspondingly bothersome.
Later reexamination of a particular area of preparation which contains cells, blood cells, etc. of abnormal type required marking of the preparation with ink on a cover sheet and locating the abnormal cells with the aid of that marking, requiring a high degree of skill on the part of the examiner. If reexamination was conducted without using a cover sheet, adjacent groups of subjects were possibly damaged, or inconvenient means such as main and auxiliary holes on a manually handled stage had to be used.
DISCLOSURE OF INVENTION
The microscope with an automatic sweeping device of the present invention comprises: subjects in a wide area; object lens of the microscope, including a position detector for detecting the position of the examination region of the container, and electro-magnetic clutches which are engaged for motor-driven operation and disengaged for manual operation; control handle for manually moving the transfer mechanism; instructions from the control console to perform automatic sweeping by stepped or continuous movement of the holder, but also controls the printer, memory means and display to print, store and display position and other various data, makes manual operation possible immediately after suspension of automatic operation, stores data of the position where the suspension occurred in the memory means and returns the holder to the position where the suspension occurred to resume sweeping operation whenever automatic operation is restarted, moves the holder 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.
Therefore, switching between automatic and manual sweeping can be accomplished easily. The device permits reexamination to be performed reliably and quickly by instantly memorizing a particular position in terms of coordinates and keying in the values of the coordinates or the memorized number at the time of reexamination. Furthermore, setting of an examination position for automatic sweeping can be performed while observing the X-Y coordinate data displayed on the position display so that any necessary examination position can easily and accurately be set.
