That is, as shown in FIG. 4, when the retroreflective angle θ of the retroreflective groove 320 is exactly 90 °, when the distance between the user and the retroreflective unit 300 is close, the left projector 210 is located. Since the image irradiated from the right and the right projector 220 has a narrow range of the retroreflective area, which is the left and right recognition areas L and R, which are reflected from the retroreflective unit 300, the image is not recognized by the left and right eyes of the user. There is a problem in that the image implementing apparatus using the portable projector according to the present invention cannot be used.

Accordingly, in order to improve this, the range of the retroreflective area, which is the left and right recognition areas (L) (R), is extended by the extension angle (α, or observation angle), so that the retroreflective angle is widened. Even if a plurality of users can use or personal use, even if the distance between the left and right eyes and the screen member 310 has a narrow advantage that can be used.

Even if the ultra-large screen is configured, a bright screen can be realized without deterioration of brightness, and as the brightness is high, the light output of the left projector 210 and the right projector 220 may be increased even during the day.

In the image realization apparatus using the portable projector according to the present invention, in implementing a 3D image, the image irradiated from the left projector 210 is recognized only in the left eye recognition region L, and the image irradiated from the right projector 220. Since the image is only recognized in the right eye recognition region R, there is no image interference between the left and right eyes. As a result, when the image irradiated from the left projector 210 and the image irradiated from the right projector 220 are photographed and irradiated with a 3D image device, the 3D image can be efficiently implemented, thereby reducing fatigue even for long time use. Has the advantage.
