Abstract

The present invention uses a mirror and a power motor and adjusts the tilt of the mirror plate with an angle adjusting screw so that the projected video can be periodically and dynamically projected onto the screen.

Description

Automatic moving picture projection angle controlling system using motor and mirror.}

In addition to the present invention, a reflection method using a mirror is widely used for adjusting the angle of a moving image or a screen projection direction of a transmission or reflection method on a screen using a reflectance [gain], as known in the art. However, the motor according to the position of the mirror fixing plate (3) attached to the mirror (5) by using the characteristics of the motor (automatically convert the angle of rotation, left, right, up and down) as in the present invention and arranged on the rear of the mirror When the power transmission shaft 2 and the mirror angle adjusting screw 4 are adjusted to the intended use, the entire video screen projected by the projection 12 is automatically moved while having periodicity in the screen 10. As such, it can be differentiated from the conventional display board or other video advertisement media, and can be a method that can focus the gaze when the entire video screen is composed while moving on the screen.

Therefore, the present invention maintains the wear resistance and the firmness of the screw 4 at the part where the fixing plate 3 and the motor power transmission shaft 2 to be fixed to the mirror are grounded at the mirror angle adjusting screw 4 and after adjustment of the angle in use. There is no difficulty in fixing, and the power of the motor (1) can be freely transmitted to the motor power transmission shaft (2), the mirror fixing plate (3), the mirror angle adjusting screw (4), and the mirror (5). ) Performance should be determined. In addition, the motor (1), the mirror plate support angle adjustment screw (6) is the motor (1), the motor power transmission shaft (2), the mirror fixing plate (3), the mirror angle adjustment screw (4) and the motor mirror plate support (7) The support pillar 8 and the angle adjustment and fixing and the arrangement of the wire (11) is to be prevented and manufactured to be wear-resistant. In addition, the distance from the projection device 9 and the mirror 5 according to the angle at which the mirror 5 is moved so that there is no loss of light when the moving picture screen projected by the projection device 9 is reflected on the mirror 1. Determine the size of.

DESCRIPTION OF SYMBOLS 1: Motor 2: Motor transmission shaft 3: Mirror fixing plate 4: Left-side screw of mirror angle adjustment 4a: 4 Right screw of 4b: 4 5: Mirror 5a: Mirror horizontal axis 5b: Mirror vertical axis 5c: Mirror center 6: Mirror plate Left-hand screw for the support angle adjusting screw 6a: 6 Right-hand screw for 6b: 6 7: Motor and mirror fixing plate Support 8: Support post 9: Video projection machine, 10: Screen, 11: Wire, 12: Projection

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is the overall configuration of the angle adjustment device of the projected video screen, the position of the motor and the motor power transmission axis, mirror fixing plate, mirror angle adjusting screw, mirror, mirror plate support angle adjusting screw, motor mirror plate support, support column, It is a schematic diagram explaining the projection apparatus, screen, and projection direction as a whole. Reflective mirrors can be configured in two ways: no power and no power. In addition, the position of the mirror can be installed at least one non-powered mirror, if necessary, depending on the direction and distance to the screen and the position, and the video screen angle adjuster and the projection device shown in Figure 1 can be integrally composed or separated. Make sure

Figure 2 is a perspective view showing the horizontal axis (5a) and the vertical axis (5b) of the mirror in the perspective view of the position of the mirror fixing plate and the position of the mirror fixing plate on the rear of the mirror is arranged by moving from the center of the mirror, the screw for adjusting the mirror angle is a motor This is a configuration diagram fixed to the power transmission shaft so that the mirror fixing plate can be placed on the rear of the mirror plate in a fluid manner as the motor moves. In addition, when the mirror fixing plate is disposed on the central axis of the mirror and when the power of the motor 1 is turned on or off, there is the same effect as the mirror plate of the powerless reflection type.

3 shows the position of the mirror fixing plate 3 and the motor 1, the electric wire 11, the motor power transmission shaft 2, the mirror fixing plate 3, the mirror angle adjusting screw 4, the mirror central axis 5c and the motor. And the configuration of the mirror fixing plate support 7 projected from the side. At this time, depending on which position the mirror fixing plate 3 is located off the central axis of the mirror, the shape of the projected moving image screen on the screen 10 is determined. Similarly, depending on which angle is fixed between the motor power transmission shaft 2 and the mirror fixing plate 3 with the mirror angle adjusting screw 4, the shape of the projected moving image screen is determined on the screen. The performance of the motor is determined by setting the number of revolutions (rpm) and the automatic adjustment of the up, down, left, and right angles for the purpose. The proper angle between the mirror fixing plate (3) and the mirror angle adjusting screw (4) should be determined and fixed. In this way, a series of tasks are determined according to what dynamic shape the moving image screen projected by 12 will produce on the screen 10.

4 is a configuration diagram of the positions of the mirror fixing plate support angle adjusting screws 6a and 6b, and the mirror plate supporting angle adjusting screws 6a and 6b are angled and fixed with the support column 8 and the projection machine 9 And the projection 12 angle between the screen 10 and serves to adjust the whole according to the functions of FIGS. In addition, the mirror plate support angle adjusting screws (6a, 6b) can support the structure shown in Figures 2 and 3 to facilitate the fixing after the angle adjustment and the support column (8) and the motor and the mirror fixing plate support (7) The construction is made so that the wire 11 is not damaged when the angle is adjusted, and the configuration diagram indicated by the support pillar (8) of the device of the present invention

As described above, the apparatus for automatically adjusting the video projection angle using the motor 1 and the mirror 5 deviates from the conventional standardized video projection 12 method, and also maintains the characteristics of the video or still image as much as possible. It can be expressed in the form of periodic and various live movements automatically according to the function of the motor and the mirror angle in the screen 10, and can be widely used as the screen 10 for exterior walls of apartments, buildings, glass windows, forests, Dynamic screen composition is possible on natural and artificial screens such as incisions and hills, so it is fun and attention-focusing for those who see new and aesthetic sense.
