手段のいずれかの方法が一般に採用されている。(Prior Art) In recent years, synthetic resin molded products have been frequently used for operation panels and decorative panels attached to various industrial products such as various electrical products, telephones, and front grills of automobiles. Such synthetic resin panels are used in an extremely wide range of products because they are easy to mold and color, and are inexpensive. Generally, either of the transfer means using a pot stamp or a transfer method using a pot stamp is adopted.

る問題があった。Furthermore, in the transfer means using a pot stamp, since the base film is extremely thin at 19 to 25 μm, wrinkles occur during pressing, making it difficult to perform beautiful transfer. In addition, transfer materials for hot stamping are supplied by continuously printing characters and patterns on a thin base film wound around a roll, so they are suitable for mass production but not suitable for small volume production. In addition, since good and defective products coexist in the printed area, there is a problem in that it requires a considerable amount of time and effort to check them and to prevent erroneous transfer.

体に接合される。By integrally bonding the film body (3) to the back surface of the panel body (2), the window holes (5) and letters (6) printed on the film body (3) can be seen from the surface of the panel body (2). The panel body (2) and film body (3), which appear as if they were printed directly on the panel body (2), are melted during injection molding of the panel body (2) in a mold described later. They are integrated by adhesion, and in this case, it is not preferable to use a bonding means such as an adhesive between the two because there is a risk of forming cloud-like stains in the transparent window hole (5). That is,
Both are integrally joined by only melt bonding without using adhesive or the like.

), and the corresponding second mold
A cavity (13) for molding the panel body (2) is formed in the first mold (11), and a cavity (13) for molding the panel body (2) is formed in the first mold (11).
10) is provided with a protrusion (14) for forming an opening (6). In normal molding, the protrusion (14)
is formed in the second mold (11), but in this example it was formed in the first mold (10).Thereby, the film body (3) is inserted into the first mold (10). When mounting, the projections (14) can be inserted into the apertures (6) of the film body (3) to allow accurate positioning of the film body (3).

することが有効であると考えられる。In addition, (16) is a vacuum suction path formed in the first mold (10) for sucking the inserted film body (3). When the film body (3) is inserted into the mold (1o), the film body (3) is stuck in the recess (12) probably due to heat or electrostatic adsorption, but vacuum adsorption is not possible. Actually it's not necessary. It is believed that applying vacuum suction is effective when the film body (3) is particularly thick.
