The present invention is characterized by viewing the image of the telescope in particular of the tourist telescope used in the tourist spot, etc. on the screen, aiming the observation target and observe the magnified image on the screen at the same time the aimed observation and the magnification observed on the screen The present invention relates to a screen telescope, characterized in that the image is displayed on the screen bright enough to be seen even in the daytime.

Conventional tourist telescopes, which are used in conventional sightseeing spots, are mainly inconvenient to use because the two eyes should be closely attached to the eyepiece, and the object to be observed is first measured with the eye first, then aiming the direction of the telescope in that direction, and then again the eye to the telescope eyepiece. It was very inconvenient to observe closely.

The present invention makes the observation of the telescope seen through the eyepiece only on the screen, which makes the observation very convenient and at the same time provides a clear image even in a bright place where the image projected on the screen is enlarged. It is intended to provide a structure of a telescope for observing screen images simultaneously.

.

As shown in Figs. 1 and 2, the objective lens 2 is formed in front of the barrel 1 structure, and the multiplier lens 3 is placed in front of an image pickup tube 4 device such as a CCD for converting an image of light into an electronic signal at the rear of the barrel 1. ) And combines the above components into one system, and combines them with the focusing device (5) configured to move back and forth.

The output signal of the imaging tube 4 is linked with the projector 6 and the image projected by the projector 6 is reflected by the reflector 7 and projected onto the screen 8 installed on the upper end of the outer end of the barrel 1. do.

The lower part of the screen 8 forms a sighting mirror 9 made of a transparent material such as glass having a sight line 9a formed at the center as shown in FIG. 3, and forms a horizontal axis with the sight line 9a at the rear end of the barrel 1. Configure the scale (10) in the.

As shown in Fig. 1 and Fig. 2, the barrel 1 is coupled to an up-and-down adjustment table 12, which allows the barrel 1 to rotate up and down within 160 °, and the up-and-down adjustment table 12 again rotates ( 13), but should be configured to rotate left and right within 359˚.

In the present invention as described above can be combined with a general small projector.

However, the projector 6 which uses LED or the laser itself as a light source is suitable.

This LED or laser light source has a long service life and low heat, so the projector itself can be configured in a small size, so it is easy to combine. Projectors with LED or ray light sources have the disadvantage of low brightness.

Therefore, as shown in FIG. 5, a spherical screen 8a having a high reflectance is used.

The spherical screen 8a has a 1/2 position of the radius of curvature R of the spherical surface to be the focal position f2, so that the light incident on the spherical surface at the focal position f2 is reflected back as shown in FIG. The observer sees a, a range of inverted angles that go straight ahead, so he sees a uniform picture.

In other words, when the projector 6 is configured at the focal position f2, even if the surface reflectance of the spherical screen 8a is increased to 5% -40%, a uniform image can be realized and so-called hot spot phenomenon can be eliminated. The brightness can be increased from 5 to 40 times that of a typical screen with 1% reflectivity.

Of course, the viewing angle of the screen is within a range of the spherical screen 8a as shown in FIG. 4, but the viewing angle of the screen has an advantage that only an observer can observe.

Spherical screen (8a) has the advantage that the image of the telescope observed by the magnification action by the reflectance and the spherical surface enhances the stereoscopic effect as the magnification action of the spherical curvature.

In more detail, the image of the telescope is important to the stereoscopic effect, and the image of the telescope by the spherical screen 8a is used to enlarge the three-dimensional effect by enlarging the distance between the images in the sphere as much as the magnification of the focal length of the screen. will be.

The present invention meets the first focal point formed in front of the multiplication lens 3 at the focal point where the focal f of the objective lens 1 falls as shown in FIG. 3 and is generated at the rear end of the focal point of the multiplication lens 3. 2 Focus is imaged on the imaging tube (4).

The image of the imaging tube 4 is converted into an electronic signal and then input to the projector 6 and projected onto the screen 8.

The scratch tube 4 and the multiplication lens 3 are fixedly coupled to each other and moved by the focus adjusting device 5 so as to match a focal point f that varies according to the distance of the object of the objective lens 2. 4).

Therefore, the present invention eliminates the conventional eyepiece structure and combines the imaging tube 4 and the multiplication lens 3 in the same portion and replaces it with the projector 6 and the screen 8 of the optical structure corresponding thereto.

The magnification of the present invention is based on the distance between the objective lens 2, which is the first focal length of the objective lens 2, and the observation object, and the objective lens 2, which is the second focal length of the objective lens 2, and the inside of the barrel. It is known that the magnification is determined based on the focal length formed at the position of the imaging tube 4.

Therefore, it is known that the longer the focal length of the objective lens is, the larger the magnification is. Therefore, the larger the magnification, the longer the length of the barrel 1 is.

Typically, the power of such a telescope is 20-50 times.

The magnified telephoto image is observed on a 14 "-40" screen 8 which is 4-10 times larger than the 3 "telephoto image magnified by the conventional eyepiece, so the total magnification is 80x-500x. It is possible to watch

The present invention coincides with the aiming line 9a at the center of the sighting mirror 9 positioned on the same horizontal line as the scale 10 installed at the rear end of the barrel 1 as shown in FIGS. 2 and 3. Aim the observation so that the objective lens (2) of the barrel (1) coincides with the observation.

As the observations matched above appear on the screen 8 as it is, the observer can observe the observation object and the magnified telescope image at the same time, and thus, the knob 11 can be moved to simultaneously observe and observe the observation. It is.

The present invention comprises a reflector composed of a prism or a reflector at a portion in which the optical path of the objective lens 2 is bent in the barrel 1 by constructing a structure of the barrel 1 in the up and down directions, as shown in FIG. 6. 7a) can reduce the length of the barrel (1) in half, so that the overall structure of the present invention can be shortened.

As shown in FIG. 5, the screen 8 structure may be replaced by an image screen 8b which is an image structure of a flat screen such as an LCD or a PDP.

Also in this case, the effect is the same as above.

As shown in FIG. 6, the structure of the barrel 1 is configured in the left and right two stages in the up and down directions, and the image screen 8b structure such as LCD or PDP is configured on the rear side instead of the screen and projector structure on the front side of the rear stage. Can be.

As shown in FIG. 7, the barrel 1 structure is configured as a two-stage structure in the up and down directions, and the image screen 8b is configured at the rear side.

That is, FIGS. 5, 6, and 7 replace the screen 8 with an image screen 8b such as an LCD or a PDP, and combine the image screen 8b with the outside of the barrel 1 structure to form an integrated structure. And the barrel (1) structure is characterized in that it is configured to combine with the upper and lower adjusters 12 and the swivel 13 again

The present invention can be applied in the same logic to the astronomical telescope, and can be applied to the general office or school by replacing the lower support structure 14 with a tripod, can be configured in the same logic for ships, military, security guards. have.

In the present invention, the projector 1, the screen 8, and the sighting mirror 9 coupled to the barrel 1 and the barrel 1 are simultaneously integrated by the vertical adjustment table 12 and the rotating table 13. Since the present invention can simultaneously observe the telephoto image magnified at the same time as the observation object on the screen (8), it is possible to observe the magnified image with high three-dimensional sense at the same time as the observation.

In addition, the conventional telescope magnification seen with the conventional eyepiece can be enlarged up to 4-10 times on the screen, and the image of the spherical screen 8a can increase the brightness up to 40 times compared to the normal screen. It can be used in bright tourist places.
