Summary:PROBLEM TO BE SOLVED: To provide a spatial indication device installable at an arbitrary point. SOLUTION: A beam of light oscillated from a laser light beam 1 is separated into its spectrum components by a half mirror 2; after a light path is adjusted by mirrors 3, 8, 9, a hologram recording material 6 is irradiated with two beams of light through diffuse lenses 4, 10 and magnifying lens 5 for forming a hologram; and visually recognizable transmitting information can be image-formed in a space in front of the hologram mirror by irradiating the hologram mirror with the light sources.
