The present invention relates to an ink supply device for a three-dimensional surface printing apparatus. The ink supply device is connected to an arm unit of a driving device for transferring an image on the surface of a printing target in order to enable uniform and continuous transfer corresponding to the surface profile of the printing target and transfers an ink on the outer periphery surface of a rotating pad which rotates and comes in contact with the printing target along the surface profile. The ink supply device includes: a printing disc including a metal plate layer and a resin layer which is coated on the upper surface of the plate layer and has a pattern groove of a preset image; a conveying device including a guide rail unit extended in a longer width direction from a side of the printing disc, a conveying arm unit moved along the guide rail unit, and a driving unit applying a conveying signal to the conveying arm unit; an ink storage unit which is connected to an end of the conveying arm unit and includes a built-in magnetic member arranged near a storage space storing the ink to fill the pattern groove; and an ink supply unit including a scraper unit which is arranged along the edge of the lower surface of the ink storage unit and has the ends coming in close contact with the upper surface of the printing disc. |
