As a conventional image display for a simulator, a concave mirror is installed in front of the viewpoint, a rear screen is installed diagonally above the viewpoint, and an image projection device is installed behind and above the rear screen. In this case, since the heavy image projection device is installed in a high position, the center of gravity including the structure that supports it becomes high, and the entire device is large and heavy.
To solve this problem, an image projection device is installed near the viewpoint, the image is reflected by a concave mirror, and an image is formed on a front screen installed diagonally above the viewpoint.The image is then enlarged and projected again by the concave mirror, and then The image is taken as . This allows the image projection device to be installed at a low location, making it compact and having a low center of gravity.

As shown in FIG. 3, in the conventional technology, a concave mirror 2 is installed in front of a viewpoint 1, a rear screen 6 is installed obliquely above the viewpoint 1 and near the focal plane of the concave mirror 2, and an image projection device is installed. There is a method of projecting the image No. 4 onto the rear screen 6. Since this device is generally used as a simulated visibility display device for a simulator for aircraft pilot training, it is installed in a simulated cockpit 5 as shown in FIG. The simulated cockpit 5 is installed in a hydraulic rocker 7 and provides a simulated acceleration of the aircraft's motion. Structurally, the image projection device 4 is installed above the simulated cockpit 5.

FIG. 1 is a sectional view showing the overall configuration of the present invention, where 1 is a viewpoint, 2 is a concave mirror, 3 is a front screen, and 4 is an image projection device. A concave mirror 2 is installed in front of the viewpoint 1, and a front screen 3 is installed diagonally above the viewpoint 1 and approximately near the focal plane of the concave mirror 2.
Set up. The image projection device 4 is configured to reflect an image on a concave mirror 2 and then form an image on a front screen 3.
その結果、映像投影装置を下方に設置すること

As a result, the image projection device can be installed downward, and the center of gravity of the entire device can be lowered. Furthermore, since there is no image projection device behind the screen, it is possible to downsize the entire device.
以下、この考案の一実施例を第１図と第２図に
より説明する。
An embodiment of this invention will be described below with reference to FIGS. 1 and 2.
第１図は本考案の断面図、第２図は平面図であ
る。 FIG. 1 is a sectional view of the present invention, and FIG. 2 is a plan view.

の上に結像する。 1 is a viewpoint, 2 is a concave mirror, 3 is a front screen, 4 is an image projection device, and 5 is a part of a simulated cockpit. Concave mirror 2 in front of viewpoint 1, viewpoint 1
A front screen 3 is installed obliquely above the concave mirror 2 and approximately near the focal plane of the concave mirror 2, and an image projecting device 4 is installed on the viewing point 1 side of the concave mirror 2 and below the front screen 3. The projected image of the video projection device 4 is
It is reflected by the concave mirror 2 and hits the front screen 3.
The image is formed on the image.

である。 From a viewpoint 1, an image on a front screen 3 is seen through a concave mirror 2. front screen 3
is located almost at the focal plane of the concave mirror 2, so the image seen from the viewpoint 1 is almost at infinity. The light from the image projection device 4 is reflected by the concave mirror 2 and formed into an image on the front screen 3.
By placing the position of the camera at an appropriate location, the camera does not face the viewpoint 1, but only faces the front screen 3.
Therefore, from viewpoint 1, front screen 3
Only the image above is visible. Furthermore, as shown in FIG. 2, by installing a plurality of image projection devices 4, 4', it is possible to provide a wide field of view in the horizontal direction.
