In U.S. Pat. No. 3,141,428 there are employed one-way couplings in a plurality of arrangements in which the individual couplings are separately and in different phases driven so as to generate a quasi rotating movement. To achieve such a movement a uni-directional arrangement of the couplings is necessary, i.e. the one-way couplings are arranged so as to transmit a torque in a common direction. By arranging one-way couplings in this manner, the reversing of the output movement may be achieved only with the application of a reversing gear device, as disclosed in the first-mentioned U.S. patent. In general, a flat panel display device such as a PDP or a LCD is equipped with an antireflection film for minimizing the reflection of light incident from the outside.
As a method for minimizing the reflection of light, there exist a method (anti-glare: AG coating) in which a filler such as an inorganic fine particle is dispersed in a resin and coated on a substrate film to impart irregularities; a method (anti-reflection: AR coating) of using the interference of light by forming a plurality of layers having different refractive indexes on a substrate film; or a method for mixing them, etc.
Among them, in the case of the AG coating, the absolute amount of the reflected light is equivalent to that of a general hard coating, but a low reflection effect can be obtained by reducing the amount of light entering the eye using light scattering through irregularities. However, since the AG coating has poor surface sharpness due to the surface irregularities, many studies on AR coating have been conducted recently.
As for a film using the AR coating, a multi-layer structure in which a hard coating layer (high refractive index layer), a low reflective coating layer, and the like are laminated on a substrate film has been commercialized. However, in the case of a clear coating having no irregularities on the surface, there are disadvantages in that the anti-glare effect is not sufficient and a defect inside the display is easily visible.
Accordingly, many studies have been actively conducted to minimize the reflection of light incident from the outside while maintaining the sharpness of the image. However, as the resolution of the display increases, the degree of improvement of the physical properties is insufficient. Recently, there are cases

 In U.S. Pat. nobelium. 3,141,428 there are employed one - way yoke in a plurality of arrangements in which the individual coupling are separately and in different phase driven so as to generate a quasi rotating movement. To achieve such a movement a uni - directing arrangement of the couplings is necessary, i.e. the one - way coupling are arranged so as to transmit a torsion in a common guidance. By arranging one - way couplings in this manner, the reversing of the output movement may be achieve only with the application of a reversing gear device, as disclosed in the first - mention U.S. patent. In general, a flat panel display device such as a PDP or a LCD is equipped with an antireflection film for minimizing the reflection of light incident from the outside. 
 As a method for minimizing the contemplation of light, there exist a method (anti - glare: AG application) in which a makeweight such as an inorganic fine particle is dispersed in a resin and coated on a substrate movie to impart irregularities; a method acting (anti - reflection: AR coating) of using the noise of light by forming a plurality of layers having different refractive indexes on a substrate film; or a method for mixing them, etc. 
 Among them, in the shell of the AG coating, the absolute sum of the reflected light is equivalent to that of a general hard coating, but a gloomy reflection effect can be obtained by reducing the amount of light entering the eye use light spread through irregularities. However, since the AG coating have poor surface sharpness ascribable to the surface irregularities, many study on AR coating have been conducted recently. 
 As for a film using the AR application, a multi - layer structure in which a hard coating level (high refractive index layer), a abject reflective coating layer, and the comparable are laminated on a substrate film has been commercialize. However, in the case of a clear coating have no irregularities on the surface, there are disadvantages in that the anti - glare effect is not sufficient and a blemish inside the display is easily visible. 
 Accordingly, many report have been actively conducted to minimize the mirror image of light incident from the outside while maintaining the acuteness of the image. However, as the resolution of the display increases, the academic degree of improvement of the physical property is insufficient. Recently, there are cases
