DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a portable hot stamping apparatus 1 according to the present invention will be described. The bottomed shaft tube 2 was formed of aluminum, and two C-size batteries 3 were inserted. The base plate 4 was formed of phenol resin, and the cylindrical holder 6 was formed of polypropylene. The sheet heater was obtained by plating a sheet of polyphenylene sulfide with nickel, etching the sheet into a coil shape (FIG. 3), and electrically insulating the surface with heat-resistant glass (a commercially available sheet heater may be used). The sheet heater was attached to a base plate, one end of the coil was guided to the back surface of the base plate by a copper plate so as to be in contact with a spring, and the other end was extended to the end surface of the flange 4a by a copper plate to serve as a switch contact. This was attached to the shaft tube 2 by the cylindrical holder 6 against the bias of the spring 7 as described above, and assembled as described above.

The convex for imprinting 10 was formed by cutting a surface of a copper plate having a thickness of 3 mm to form a convex character having a height of 1.5 mm, and attached to the front surface of the sheet heater via a cylindrical curler 11. In consideration of strength, heat capacity, and economical power consumption required for heating, the stamping die 10 is suitably a copper or brass plate having a thickness of about 1 to 4 mm.

The metal film deposited film is obtained by applying a thermally decomposable adhesive to a resin film and depositing aluminum thereon.
A hot stamping film F, on which an adhesive that generates adhesive force by heating is applied, is covered on the transfer target W such that the heat-adhesive adhesive layer faces the transfer target W, and the above-described film is formed from above. 10 parts of the metal stamp of the hot stamping device were strongly pressed. As a result, the spring 7 is compressed so that the extension lead wire 5a and the shaft tube 2 come into contact with each other, a closed circuit is formed, and the temperature of the heater rises to 110 ° C. in approximately 10 seconds. The temperature rose up. At this point, one of the adhesive layers of the film was decomposed by heat and lost its adhesive force, and one of the films obtained the adhesive force and the metal deposition film was transferred to the transfer target W.

The above-mentioned metal film vapor-deposited film F is a plastic film generally used as a foil for hot stamping.

When the pressing of the metal engraving 10 against the transfer target W is released, the base plate 4 slides forward by the bias of the spring 7, the electric circuit is opened, and the power supply to the heater is stopped. In this case, it is natural that the number of times of hot stamping is limited because the electric capacity of the AA battery is small. When the AC adapter is used, it is natural that the number of times of imprinting is not limited.

Another embodiment will be described. A metal film vapor deposition film F and a stamping alignment guide frame 12 are placed on the surface of the transfer target W, and a square stamp 1 is placed in the guide frame 12.
Align 0. On the other hand, the heater surfaces were pressed for 10 seconds from the upper surface of the aligned markings 10 without heating the heaters 5 on the base plate surface of the hot stamping apparatus 2 for 10 seconds. Further, the position of the frame 12 was changed, the stamp was changed, and the above operation was repeated. This resulted in a sentence consisting of a metal coating.

[0024]

The hot stamping device according to the present invention is lightweight and excellent in safety by using a dry battery as a power source and using a planar heater.

Since the method for attaching and detaching the stamping die 10 to and from the apparatus is simplified, various hot stampings can be enjoyed.

Without mounting a stamping die on a hot stamping device, the device is appropriately placed on a metal film deposited film,
Words, idioms, names, etc. can be transcribed by pressing the heater surface, making it convenient for personal use. Further, the use of the guide frame facilitates the alignment of the inscriptions, so that beautiful transfer can be performed.
