JP1633416S - Information terminal with all-around video display function - Google Patents

Abstract

The article according to the design of the present application is an information terminal having an all-around image display function, and is used, for example, by installing it in a store or in a store. The present article includes a cylindrical screen and a reflection mirror that controls the angle of incidence of the image light emitted from the center of the pedestal on the screen, as shown in the reference diagram showing the names of the respective parts. The screen is a transmissive hologram arranged around the entire circumference of an optical axis extending in the vertical direction from the center of the pedestal. The reflection mirror has a rotationally symmetric shape with respect to the optical axis, and the image light emitted in a radial shape from the center of the pedestal upward is radially directed toward the entire circumference of the screen by the reflection mirror. Is reflected in. The reflection mirror controls the angle of incidence of the image light on the screen, and the image light incident on the screen at a substantially constant incident angle passes through the transmissive hologram and is diffused to the outside of the screen and emitted. .. This makes it possible to display an image over the entire circumference of the cylindrical screen.
