Abstract
.cndot. A holographic projection device for displaying a 3-dimensional image comprises a cylindrical base having a diagonally-cut top portion, and a figurine. The cylindrical base comprises a reflection-type hologram, a point source of white light, and a magnetic element. The figurine has a diagonally-cut bottom portion, and comprises a magnetic element. The reflection-type hologram projects an upright orthoscopic image having both horizontal and vertical parallaxes. The cylindrical base has the capability of detachably mounting the figurine with a magnetic attraction force between the magnetic elements. A downward movement of the magnetic element by gravity turns on the point source of white light when the figurine is detached. An upward movement of the magnetic element turns off the point source of white light when the figurine is magnetically attached. This invention relates to holographic projection devices for displaying a 3-dimensional image, and the principal use of the invention is for optical decoration.
Description

= A number of patents disclose holographic projection devices with different configurations for displaying holographic images.
= Canadian Application 2 277 653 discloses a "Cylindrical Holographic Display Device" for displaying an upright holographic image perpendicularly to the hologram. However, this prior art suffers from a limited viewing angle, and a small height of the upright holographic image.
= Canadian Application 2 278 110 discloses a "Holographic Display Device with a Paraboloidal Hologram" for displaying an upright holographic image perpendicularly to the hologram which has a wider viewing angle. However, this prior art applies only to transmission-type holograms, and is too complex and difficult to manufacture.
= Canadian Application 2 289 999 discloses "Holographic Statue Projection Device" for displaying an upright holographic image diagonally to the hologram which has a much wider viewing angle.
= These prior art arrangements do not provide a figurine which is magnetically mounted on a cylindrical base in order to superimpose with the 3-dimensional holographic image of a reflection-type hologram on the cylindrical base.
Description of the Invention = It is a primary object of the invention to provide a holographic projection device for displaying a 3-dimensional image having both horizontal and vertical parallaxes.
= It is another object of the invention to provide a holographic projection device with an elliptical reflection-type hologram placed diagonally in order to provide a wide viewing angle.
