DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inverted microscope for magnifying and observing an observation sample placed on a stage with an objective lens immediately below the stage, and more particularly to an inverted metal microscope for observing the structure of a metal material. It is.

[0002]

2. Description of the Related Art Conventionally, in the case of this type of inverted microscope, when recording the structure observation result of a metal material as an observation sample, it is common to take a photograph using a large-sized camera such as a polaroid or a 35 mm camera. For this reason, a photographing device such as a large-size camera or a 35 mm camera is often provided inside the inverted microscope.

However, the fact that a photographing device is always provided inside an inverted microscope is a useless function for an observer who does not take a photograph or the like. Recently, not only photographing but also a TV camera, With the diversification of image recording devices such as digital cameras, there has been a demand for an inverted microscope in which the microscope main body and the photographing device are configured separately.

[0004] The specification of Japanese Patent Application No. 2000-285637 is as follows.
An example of an inverted microscope based on such an idea is shown. In FIG. 13, reference numeral 1 denotes a microscope body (hereinafter, referred to as a microscope main body).
2 is an observation sample placed on the stage 3,
4 is a light source device such as a halogen lamp and 5 is a light source device 4
A projection tube 6 for guiding a light beam from the light source 6; a plurality of objective lenses 6 held by a revolver 7 and alternatively arranged in the optical path; 8 a half mirror for deflecting the light beam from the light projection tube toward the objective lens 6 , an imaging lens for forming an enlarged image of the observation sample 2 with the objective lens 6 is 9, 10 is a mirror for deflecting the light rays emitted from the imaging lens in the horizontal direction, the observation sample 2 these configuration primary image I ₁ Is formed.

[0005] Reference numeral 11 denotes a device that drives the revolver 7 holding a plurality of objective lenses 6 up and down to change the relative distance between the observation sample 2 and the objective lens 6 on the stage 3 to focus on the observation sample 2. Focusing handle for alignment. Also, the position of the primary image I ₁ is the scale such 12 for measuring the partial size of the observation specimen is adapted to be inserted.

[0006] The primary image I ₁ is selectively guided to two light beams of reflected light upward and transmitted light forward by a mirror 14 which can be inserted into and removed from the optical path via a zoom optical system 13. I will The light beam reflected vertically upward forms an image as a secondary image I ₂ , and after being relayed by the relay optical system 15, enters the eyepiece 17 attached to the lens barrel 16 and reaches the eyes of the observer. And observed.

On the other hand, the light transmitted forward forms a secondary image I ₂ ′ at a position protruding a predetermined distance from a front port 18 provided below the front surface of the mirror body 1. A photographing device such as a large-size camera or a 35 mm camera, and an image recording device such as a TV camera can be detachably attached to the front port 18. At the time of photography, as shown in FIG. 14 to the position of the secondary image I _2, and insert the frame reticle 19 having a pattern 19a indicating the imaging range in the photography device,
After reconfirming the area reflected on the large plate or 35 mm film, the photographing operation is completed by performing an exposure operation.

On the other hand, Japanese Patent Application Laid-Open No. Hei 8-219710 shows a scale device for taking a photograph or the like by inserting a scale-like pattern in a plane conjugate with the image position of the microscope main body. In this case, in FIG. 16, 21 is a scale device, 22-1 to 22-6 are a plurality of scales having different sizes, R is an image forming area (image plane) by a microscope observation optical system, and 23 is a scale 22-1. 22 to 24, a rotation member 24 to which the optical member 23 is fixed, and a pulley 25 for rotating the rotation member 24 via a belt 26. Then, the observer rotates the knob fixed to the pulley 25 so that the pulley 25
Rotates, and the rotating member 24 rotates via the belt 26. The optical member 23 rotates in conjunction with the movement of the rotating member,
Scales 22-1 to 22-22 are respectively provided at the ends in the image forming region R.
-6 is arranged.

Thus, the scale to be projected on the image plane can be switched by a simple operation such as rotating the knob, and the operability of changing the scale in accordance with the magnification of the objective lens can be greatly improved. In addition, one scale device can project many types of scales 22-1 to 22-6. However, there is no description about attachment / detachment of the scale device to / from the microscope main body.

A frame reticle 19 is built in the mirror body 1 so that the pattern 19a can be used even for an observer who does not take any photograph.
Is provided. This means that the mirror body 1 has an extra function, and there is room for improvement. In addition, since the frame reticle 19 is built into the mirror body 1 when taking a picture, a plurality of types of patterns 19a must be prepared according to the type of the picture taking apparatus and the type of the image recording apparatus. Assuming that a slider in which the frame reticle 19 is bonded with a bonding agent is prepared,
Even if the slider is configured to be detachable from the mirror body 1 without being built in the mirror body 1 and the pattern 19a is provided to an observer,
In order for the frame reticle 19 to be inserted into and removed from the optical path, a device and a mechanism such as a slot corresponding to the slider are provided in the mirror body 1, which is wasteful and has room for improvement in terms of cost and the like.

Here, if the scale of the scale device in JP-A-8-219710 is replaced with the above-described pattern, a frame reticle having a plurality of patterns 19a corresponding to various photographing devices and image recording devices can be used as a slider. Can have. However, in that case, there are problems that a frame reticle considerably larger than the field of view is required in order to bring a pattern other than one pattern out of the field of view, and the cost is increased due to the provision of the rotating mechanism. For this reason, it is unlikely that the mirror body is provided with a slider in which the scale of the scale device is replaced with a pattern.

Further, in the microphotographing described in the specification of Japanese Patent Application No. 2000-285637, the influence of the mechanical mounting accuracy due to the separate construction of the mirror and the photographic device, the error of the optical magnification of the mirror, etc. , As shown in FIG.
A shift may occur between the center 19b of 9a and the center 20a of the actual imaging range 20 (hatched portion). For this reason, the range of the pattern 19a is set to be smaller than the actual imaging range 20, for example. However, it is difficult for the observer to recognize the entire area to be actually photographed. And there was room for improvement in this regard.
