For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Further, detailed descriptions of well-known functions and configurations that may be unnecessarily obscured by the gist of the present invention are omitted.

As shown in FIGS. 1 and 2, the present invention is roughly divided into a press mold 100, a support frame 200, a first adsorption unit 300, a second adsorption unit 600, and a surface treatment apparatus 700 do.

 The pressing frame 100 includes an upper inner frame 110 to be pressed against the outer surface of a transfer object, a first heat transfer portion 120 for transferring heat to the object at a high temperature, And a suction unit 300.

The support frame 200 is constituted by a lower inner frame 210 which supports the upper part of the support body 200 and a second heat transfer part 220 which transfers heat to the upper body corresponding to the inner surface of the transferred object 500.

The transfer subject 500 according to an embodiment of the present invention is fixed to the lower inner frame 210 of the support frame and the transfer sheet 400 is placed on the object and then pressed to the upper inner frame 110 of the press frame 100. The heat is applied to the first heat transfer part 120 and the second heat transfer part 220 simultaneously with the pressurization.

When the first heat transfer part 120 and the second heat transfer part 220 are turned off after a predetermined time has elapsed, the first suction part 300 is turned on and the thermally sublimated transfer sheet 400 is sucked, .

The user can easily remove the adsorbed transfer sheet 400 using a tool. At this time, a plurality of first adsorption units 300 may be formed to adsorb the entire surface of the transfer sheet 400, and the transfer sheet 400 may be easily removed from the surface of the transfer sheet 400 that is not adsorbed.

The transfer paper discharge unit 900 includes a second adsorption unit 600 and a collection box. A second suction part is formed on one side of the pressing frame 100, and a collection box is formed below the second suction part 600.
