  • Patent number: 7311512
    Abstract: A three-dimensional hard copy apparatus including: a shape forming unit including plural display pins having a contact unit, which selectively contacts a thermoplastic sheet, and moves relative to a display surface and is capable of forming a predetermined pattern; a drive unit that selectively drives the plural display pins; a lock sheet that holds the positions of the plural display pins; and a fan that moves the thermoplastic sheet in a direction of the shape forming unit and brings the thermoplastic sheet into press contact with the shape forming unit, wherein the apparatus forms the predetermined pattern with the shape forming unit, holds the plural display pins with the lock sheet, and brings the thermoplastic sheet and the shape forming unit with the fan to mold a pattern of a shape matching the predetermined pattern, which is formed by the shape forming unit, on the thermoplastic sheet.
    Type: Grant

  • Patent number: 4268615
    Abstract: A method for producing a relief, which comprises forming a layer of a pattern on the surface of a sheet made of a material having the property of increasing in volume when heated, said pattern being made of a material having a stronger ability to absorb light than the aforesaid material, and then irradiating strong light uniformly on the entire surface of the sheet to selectively heat that portion of the sheet which is adjacent the undersurface of the pattern layer, whereby the pattern layer is raised from the sheet surface corresponding to the increase of the volume of the sheet portion.
