ABSTRACT:
A digital hand stamp that can print multiple images on a supporting surface. The digital hand stamp includes a frame member, an ink jet printing head, a non-volatile memory, an image selection button, a display area, and a printing control circuit. The frame member has a cavity. The ink jet printing head has one or more nozzles. The ink jet printing head can be activated to slide inside the cavity of the frame member when the digital hand stamp is pressed against the supporting surface. The non-volatile memory can store a plurality of images. The image selection button can select an image from the plurality of images stored in the non-volatile memory. The display area can display the image selected by the selection button. The printing control circuit controls the nozzles on the ink jet printing head to project an ink pattern on the supporting surface when the ink jet printing head slides inside the cavity of the frame member. The ink pattern on the supporting surface represents the image selected by the image selection button.
