  • Publication number: 20160243815
    Abstract: An embossing apparatus includes a base, a work table, a mat, a pen carriage and a first tool. The base includes a conveyance path extending in a first direction. The work table is attached to the conveyance path and moves in the first direction. The mat is arranged on the work table. The pen carriage is spaced apart from the base and moves in the second direction parallel to the major surface of the work table and different from the first direction. The first tool is arranged on the pen carriage and moves in the third direction perpendicular to the major surface of the work table. The first tool moves in the third direction and is pressed against a medium adhered on the mat, thereby forms a recess in the medium.
