Abstract: A digital textile printer includes front and rear feeding devices driven by a transfer axil within a driving panel of the front and the rear of a base to prevent distortion and wrinkle phenomena generating defective printing to perform effectively the textile printing even to very thin textile fabrics, an ink-retrieving hole along to the transfer axil on the top of the base to collect the residues of the injected ink passing through a printing material to prevent ink from spreading at the printing material, at least one suction pan in the inside of the base to collect easily the residues of the injected ink to hasten dries of ink, and a heater of rubber material in the inside of the front of the base to hasten dries of the printing material passing through the ink-retrieving hole.

Abstract: The present invention discloses a multi-purpose digital printer having a transfer roller making very thin or retractable printing material move while adhering to an adhesive on the transfer belt, to prevent twisting or wrinkling, and extension states of the printing material, so that it is possible to print not only on very thin or retractable printing material, but also on unfixed form, type or thick printing material.

Abstract: The present invention discloses an automatic ink supply device comprising: a main body installed in the one side of a printer, including a bottom supporting plate and a top supporting plate of a predetermined height with multiple supporting holes in the inside of the main body; multiple bottom tanks supported in stable in the state of penetrating the corresponding supporting holes of the bottom supporting plate, including a close cap in the top side, including a hose hole in the center of the close cap, including a nozzle hose from the inner bottom side of the close cap to the outside of the main body, and including a nozzle in the end of the corresponding nozzle hose connected to the printer, respectively; and multiple top tanks supplied by ink with different colors from one another in the state of penetrating the supporting holes of the top supporting plate, including a supply hose with an O/C (open/close) valve in the bottom side, maintaining an amount of charged ink constantly in the corresponding bottom
