BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a microscope optical element display device for displaying the function of an optical element such as an optical filter that can be inserted into and removed from the optical axis of an observation optical system of a microscope.

[0002]

2. Description of the Related Art A microscope is provided with a plurality of optical elements having different functions, such as a dichroic mirror, an excitation filter, and an absorption filter, and is inserted into and removed from the optical axis of an observation optical system while switching these optical elements. It is intended to be a speculum. In such a microscope, it is necessary to indicate what function the optical element inserted into the optical axis of the observation optical system has.

As a display method of such an optical element, an optical filter will be described as an example. Each type of optical filter is treated as a unitized filter block.

[0004] In the display method, each filter block identification display (hereinafter, abbreviated as a display) describing the filter function of the filter block is provided at the rear of an epi-illumination light projecting tube of a microscope which cannot be seen by a microscopic person. There is a type in which a corresponding display body is selected from each of the display bodies at the time of microscopy and transferred to a display body mounting portion at the front of the epi-illumination light projection tube for identification.

[0005] As another display method, the names of various optical filters are described at the tip of a push-pull type knob, and the optical filter inserted into the observation optical system by rotating the knob is referred to by an observer. Some are identified.

As another display method, the display body is stored separately from the microscope, and the display body corresponding to the optical filter to be inserted into the observation optical system is selected to display the display body at the front of the epi-illumination light projection tube. Some are transferred to the body attachment part and identified.

[0007]

However, in the method of storing the display body at the rear of the epi-illumination light projection tube which is not visible to the examiner, it is impossible to store all the optical filters, so that the display body cannot be stored. The display must be kept separately. Further, in this method, there is a possibility that the display may be lost, and further, a display different from the inserted optical filter may be erroneously selected and used.

Further, the method using the push-pull type knob can cope with each optical filter described at the tip of the knob, but cannot cope with various optical filters not described in this knob. It cannot cope with expansion of various optical filters.

Further, in the method of storing the display body separately from the microscope, there is a high possibility that the display body is lost, and a display body different from the inserted optical filter is erroneously selected and used as in the above method. There is a fear.

Accordingly, the present invention provides an optical element display device for a microscope which can select and display a display body corresponding to the function of an optical element inserted into an observation optical system of a microscope without error, and which does not cause the display body to be lost. The purpose is to provide.
