BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a projection microscope which can be used by being converted into a sketch mirror for copying a projected image of a screen plate on a tracing paper and a viewer for visually observing the projected image of the screen plate. .

[0002]

2. Description of the Related Art Conventionally, there is known a projection microscope which irradiates a preparation observation material with lamp light, enlarges it with a lens barrel lens, and projects it on a screen plate.

[0003]

The conventional projection microscope is used as a viewer for visually observing the projected image of the screen plate, and is used as a sketch mirror for copying the projected image of the screen plate on tracing paper. There was a problem I could not do.

The present invention has been devised to solve the above-mentioned conventional problems, and an object thereof is to provide a projection microscope which can be used as a sketch mirror and a viewer by turning the projector up and down. Especially.

[0005]

In order to achieve the above object, the projection microscope of the present invention illuminates an observation material of a preparation with lamp light, magnifies it with a lens barrel lens, and projects it on a screen plate. And a preparation lens and a curved arm projecting on the mounting plate, and a condenser lens is incorporated in a light-transmitting hole of the preparation glass component, and the observation material of the preparation is irradiated from below to a position below the lens. And a microscope base incorporating a light-projecting lamp that can be turned off, a lens barrel incorporating a projection lens that is fitted into a front end hole of the microscope frame arm, a light projecting port for emitting light transmitted through the lens of the lens barrel upward, and A support frame having a pair of brackets standing up from both sides of the light projecting port and fitted and held on the curved arm of the microscope base, and a projection port having an end face opening into which the screen plate is fitted are provided. Become vertical A projector that is pivotally supported by the support frame bracket so as to be tiltable and tiltable so as to be able to switch between a Ketch use state and a viewer use state in which the projection opening is tilted forward at a predetermined angle with respect to a vertical center line. A support frame swingably supported in the projector and a supporting frame when the projector is erected and rotated in a sketch use state. A supporting frame is suspended and stored at a rear position of the light projecting port when the projector is tilted in a viewer use state. A reflecting mirror is provided which is in contact with a stopper projection of the bracket and reflects the light transmitted through the lens in the direction of the viewer projection port and is supported by being converted into a tilted and tilted state.

[0006]

According to the projection microscope having the above construction, when the projector is vertically erected and rotated, the reflecting mirror is suspended and stored at the rear position of the support frame light projecting port. Then, the observation material of the slide is illuminated by the lamp light, enlarged by the lens barrel lens and projected on the screen plate, so a sketch of copying the projected image of this screen plate on the tracing paper placed on the screen plate. Can be used as a mirror.

When the projector is tilted to a viewer use state in which the projector is tilted forward at a predetermined angle with respect to the vertical center line, the reflecting mirror contacts the stopper protrusion of the support frame bracket to project the lens transmitted light by the viewer. It is supported by being converted to a tilted and tilted state in which it reflects toward the mouth. Then, the observation material of the slide is illuminated with the lamp light, enlarged by the lens barrel lens, reflected by the reflecting mirror in the direction of the viewer projection aperture, and enlarged and projected on the screen plate, so that the projection image of this screen plate is projected. It can be converted and used as a viewer for visual observation from the front.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to the drawings.

In the figure, reference numeral 1 denotes a microscope stage composed of a battery case 2 and a holder 3. The microscope stage 1 has a slide mount portion 4 and a curved arm 5 projecting above the mount portion. A configuration in which a condenser lens 6 is incorporated in the light-transmitting hole 4a of the mounting portion 4 and a projection lamp 7 capable of lighting and extinguishing the observation material (not shown) of the slide P is illuminated from below at a position below the lens. Has become.

The projection lamp 7 is electrically connected to a dry battery housed in the battery case 2 and a switch (not shown), and is turned on and off by turning the switch on and off.

Reference numeral 8 is a lens barrel which is fitted into the front end hole 5a of the arm 5, and two projection lenses 9 and 10 which are convex lenses are incorporated in the lens barrel 8 as shown in the drawing. Reference numeral 11 denotes a synthetic resin support frame which is fitted and held on the curved arm 5 of the microscope stage 1, and includes a light projecting port 12 for upwardly emitting the lens transmitted light of the lens barrel 8 and both sides of the light projecting port 12. A pair of brackets 13 standing upright from the top and a hooking projection 1 for locking the rotation of the projector.
4 and 15, and a stopper protrusion 16 is provided on the inner side of the bracket 13 facing each other.

Reference numeral 17 denotes a projector made of synthetic resin, which is constructed by connecting a pair of left and right projection frames, and the projector 17 has a square-shaped end face opening 1 into which a screen plate 18 is fitted.
2, the projection opening 19 is vertical and the projection opening 19 is vertical as shown in FIG. 1, and the projection opening 19 is at a predetermined angle θ (for example, 105 degrees) with respect to the vertical center line O as shown in FIG. A support pin 20 is pivotally supported by a support frame bracket 13 so as to be tiltable and tiltable so as to be able to switch to a tilted viewer use state.

The projector 17 is provided with a body notched circular arc hole 21 for permitting the above-mentioned turning up and down, and is engageable with and disengageable from the hooking projection 15 in the upright turning state as shown in FIG. A mating bulge 22 and a hook 23 that engages removably with the hook 14 in the tilted state as shown in FIG. 2 are provided.

Reference numeral 25 denotes a reflecting mirror in which a mirror 27 is fitted and adhered to a mirror frame 26, and the reflecting mirror 25 is pivotally supported in the projector 17 by a pivot pin 24 so as to be swingable. When 17 is erected and rotated in the sketch use state, it is hung down and stored at the rear position of the support frame light projecting port 12 as shown in FIG. As shown in FIG. 2, the lens 16 is brought into contact with the lens 16 to be converted and supported in a rearwardly tilted state in which the lens transmitted light is reflected toward the viewer projection port 19.

When the projection lamp 7 is turned on in the state shown in FIG. 1, the observation material of the preparation P is irradiated with the lamp light and enlarged by the lens barrel lenses 9 and 10, and the screen plate 1 is enlarged.
Since it is projected onto the screen 8, the projected image of the screen plate 18 can be used as a sketch mirror for writing on the tracing paper 18a placed on the screen plate 18.

When the projector 17 is tilted to a viewer use state in which it is tilted forward at a predetermined angle θ with respect to the vertical center line O, the reflecting mirror 25 abuts on the stopper projection 16 of the support frame bracket 13, Since it is supported by being converted to a rearwardly tilted state as shown in FIG.
In step 5, the image can be reflected in the direction of the viewer projection port 19 and enlarged and projected on the screen plate 18, and the projected image of the screen plate 18 can be converted and used as a viewer for visually observing from the front of the projection port.

[0017]

Since the projection microscope of the present invention is as described above, it can be used as a sketch mirror and a viewer by turning the projector 17 up and down. Since the state of is automatically changed,
It has excellent practical effects such as the need for switching the reflecting mirrors.
