For example, the conventional method for producing transilluminated display boards for transilluminated instruments is to print translucent characters, scales, etc. on the surface of a transparent or translucent resin substrate that has been preformed into a predetermined shape using silk printing means. The transfer foil was constructed by transferring a transfer foil onto the surface of the resin substrate or the resin substrate using pressure and heating means.
Since a molding process for forming such a conventional transmitted illumination substrate and a printing means or transfer process for applying translucent characters, scales, etc. on the formed resin substrate are required, these two steps improve productivity. There were problems such as bad ones or higher costs due to increased labor costs.

られるものである。 Next, the manufacturing process of the transmitted illumination type display board 1 having the above structure will be described. Reference numerals 9 and 10 are a pair of molds for forming the intended transmitted illumination type display board.
Cavity 11 between these two molds 9 and 10
Then, a transfer foil 14 with a transfer material 13 temporarily held on the base film 12 is positioned. The details of the superposition structure of the base film 12 and the transfer material 13 are shown in FIG.
The release layer 131 is temporarily attached to the base film 12.
A light-transmitting colored layer 132 formed on one side of this peeling layer 131; and a light-shielding layer 133 formed on one side of this light-transmitting colored layer and polymerized except for the transilluminated display characters 8. The transfer material 13 is formed on one side of the base film 12 wound in a roll at regular intervals. This is what is being done. After the transfer material 13 held by the base film 12 is positioned in the cavity 11 together with the base film 12 as described above, both molds are closed, and the cavity of the mold is closed. A transparent molded member 15 is formed by press-fitting a transparent resin material into the inside of the molded member 11 . In this way, the molds 9 and 10
By filling the cavity 11 with a transparent resin material to form a transparent molded member 15,
On one side of the molded member 15, the above-mentioned transfer material 1 is
3. Transfer material 1 that is exactly integrated with base film 12
3 are attached together via an adhesive layer 134 (see FIG. 2). Next, after releasing the molded member 15 that is integral with the base film 12 and the transfer material 13, as shown in FIG.
By peeling 2 together with the peeling layer 131 from the colored layer 132, the transmitted illumination type display board 1 shown in FIG. 1 can be obtained.

トを低減せしめることができる効果がある。 As described above, according to this embodiment, when injection molding a transilluminated display board using a mold, the transfer material 13 is set in the mold corresponding to the cavity,
After that, the molding material is filled into the cavity and the molded member 15 is injection molded, so when the molded member 15 is molded, the molded member 1 is
Transfer material 13 having translucent display characters 8 on one side of 5
are attached together. Therefore, it is possible to obtain a transilluminated display product in which the transfer material is attached to the molded member 15 at the same time as the molded member 15 is injection-molded. Compared to the manufacturing method of transilluminated display products in which the transfer material is pasted in a secondary process, the step of pasting the transfer material can be omitted, which has the effect of increasing productivity and reducing product costs.
