以下、この発明を図示の例により詳説する。[Means for Solving the Problems] This invention for the above-mentioned purpose includes a mold in which a protrusion for forming a required recess on the back surface of a molded product is attached to the back surface, and a gear that is closed with the mold. A transfer film with a transfer foil having a color or pattern applied to one side of the film base at a position corresponding to the small recess of the above-mentioned molded product is placed between the mold and the mold. A film base is placed on the side of the above-mentioned back molding rod, and a transparent resin is injected into the cavity under the intervening transfer foil to mold the molded product, and at the same time, the film base is placed in the molded recess. Alternatively, the above conventional problems can be solved by transferring the pattern. - This invention will be explained in detail below using illustrated examples.

に転写フィルム１１が送り出されるようになっている。The transfer film 11 has a film base 12 attached to a male mold 1.
Attached to the top and bottom of the movable platen 8 to the side, the hooks are passed to the foil feeding device 14 and placed between the two molds. Also, although omitted in the drawing, the color or pattern of the transfer foil 13 is fixed in the blank space in the mold (O, L, etc.) so that the color or pattern of the transfer foil 13 can be applied to the protrusion 3 or a predetermined part of the protrusion 3 and the mold surface 2. The corresponding position 11 is set to 1, so that the transfer film 11 is sent out every time it is formed.

。Next, when the mold is opened, the molded product 1 together with the transfer film 11
5 remains on the male mold 1 side. This molded product 15 is
: When the mold is released, the transfer foil 13 is peeled off from the base film 12 and transferred to the molded product 15. Further, the base film 12 remaining between the molds is sent out from between the molds for the next process, and a new transfer foil 13 is jetted between the molds.
第３図に示す成形品１５は、中央の凹部１５ｂを含めて
裏面１５ａのすべてに転写箔１３を転写したものである
が、この転写は部分的にも実施し得る。The molded product 15 shown in FIG. 3 has the transfer foil 13 transferred to the entire back surface 15a including the central recess 15b, but this transfer can also be performed partially.
