Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a hand-held projection observation mirror that projects a film image onto a screen plate using sunlight for observation.

[Prior art] Conventionally, an observation mirror body having a screen plate has two film winding shafts that can change the film screen by dial operation, and a screen plate that reflects sunlight in the direction of the window hole of the main body. A hand-held projection observation mirror equipped with a reflecting mirror for projecting images is known.

[Problems to be solved by the invention] The conventional projection observation mirror is used only by setting and observing a film prepared in advance, and it is not possible for the user to set and use an animation film that the user has made himself. This is not possible, and even if it were possible, there was a problem in that the operation of exchanging the preset film and the animation film created by the user was troublesome.

[Means for Solving the Problems] In order to solve the above-mentioned problems, this invention has two film take-up shafts that can change the film screen by dial operation, and a screen plate that projects the film screen. The film magazine made by the camera can be attached to the front part of the observation mirror body for observation.
This film magazine is characterized in that the film magazine is removed and the animation film created by the user is inserted laterally into the window hole of the main body so that it can be viewed.

[Function] It is possible to observe the magazine film prepared in advance or the animation film made by the user, and in that case, to change the film, remove the film magazine and insert the animation film made by the user into the main body. This can be done easily and quickly by simply passing it through the window hole.

[Example] Hereinafter, an example of this invention will be described in detail with reference to the drawings. In the figure, 1 is a robot-shaped main body made of synthetic resin, and this main body 1 has a 47 mm x 33
It has a rectangular window hole 2 with a size of about mm, and a magazine locking portion consisting of an elastic locking piece 3 and an engaging piece 4 is provided at the upper and lower positions of the window hole 2. As shown in Fig. 3, the box structure is such that the rear upper surface is open and has a concave groove 6 and four film holding claws 7 on both left and right sides of the box, through which the animation film 5 made by the user is inserted laterally, as shown in Fig. 3. . In addition, on the top of this main body 1, there is a semicircular plate-shaped shadow plate 11,
Guideline 12 for examining the shadow of the sun on this board surface
Eyeball-shaped movers 13a and 13b that are movable along the peripheral edge of the shadow plate 11 are provided.

8 is an inclined angle θ of about 55 degrees with respect to the main body window hole surface on the inclined plate 9 located behind the window hole in the main body 1.
This mirror is attached with 8
serves to reflect sunlight R taken in through the upper opening 10 at the rear of the main body toward the window hole 2 as shown in FIG. Reference numeral 14 denotes a film magazine which is removably hooked to the front surface of the main body 1 and positioned and mounted as shown in FIGS.
Alternatively, two film take-up shafts 16 that can be changed by operating 16b and a screen plate 17 that projects the film screen 15a as shown in FIG. 2 by reflecting sunlight R are attached to a magazine case 18 with an open rear surface. The magazine 14 (magazine case The screen plate 1 is installed in the screen plate mounting opening 18a of 18).
A vertically movable shutter plate 19 that closes the lower half of the shutter plate 7 is provided. Incidentally, the magazine case 18, which is positioned by the front protruding edge 1a of the main body 1, has an elastic engagement part 18b that engages with the elastic locking piece 3 and the engagement piece 4 of the main body 1 as shown in FIG. 18c
are integrally provided.

The projection observation mirror having the above structure is constructed by holding the main body 1 in the hand with the film magazine 14 attached as shown in FIGS. 1 and 2 and directing the mirror 8 inside the main body toward the sun. If the sunlight R is received as shown in FIG. By advancing the film by rotating the dial while viewing the projected image, the film screen 15a can be observed one frame at a time.

Furthermore, by removing the film magazine 14 from the main body 1 and inserting another film 5 made by the user into the window hole 2 of the main body as shown in FIG. 3, the mirror reflection of sunlight R as described above can be achieved. Therefore, since the screen 5a of the film 5 is illuminated from the rear,
This film screen 5a can be clearly observed outdoors.

[Effect of the invention] Since this replacement projection observation mirror is as described above, it is possible to observe a magazine film prepared in advance or another animation film made by the user. Moreover, the film can be changed easily and quickly during this switching operation by simply removing the film magazine and inserting the animation film created by the user into the window hole of the main body. .

[Brief explanation of the drawing]

Figure 1 is a central vertical sectional view showing the projection observation mirror of the present invention with a film magazine attached, Figure 2 is a perspective view of the observation mirror with the magazine attached, and Figure 3 is an animation film made by the user. FIG. 2 is a perspective view of the device in use when it is worn and observed. DESCRIPTION OF SYMBOLS 1... Main body, 2... Rectangular window hole, 3...
