PURPOSE: A hologram board body which has multiple hologram boards forming a hologram pattern stacked on an outer surface, a manufacturing apparatus thereof, and a method thereof can easily build a hologram pattern building board. CONSTITUTION: The manufacturing apparatus of a hologram board body (A) comprises a hopper (11), a fusion forming unit (1), a pressing roller (2), and a combining roller (4). Multiple hoppers supply a suitable synthetic resin for building a board. Multiple fusion forming units heats to the temperature in which a synthetic resin is fused and discharges a fused synthetic resin in the inner side. Multiple pressing rollers forms a hologram projection layer forming a hologram pattern on the surface of it when the synthetic resin discharged from the fusion forming unit is hardened on the board. The combining roller presses multiple hologram boards (b) in unhardened state passed the pressing roller to form one hologram board (B). |
