For example, the surface tension is small, and the chemical structure and polarity of the paint are similar to those of the base material 10a of the case 10.
Further, the selection conditions of the paint include solvent resistance, chemical resistance and safety, but these conditions are excluded when the inside of the housing is painted. When painting the inside, there is no problem because disinfection or other effects on the human body do not come into contact with the paint. The coating material has a range of choice depending on the material of the base material 10a of the housing 10 made of a resin having transparency to be coated, but is roughly classified into a solvent evaporation type self-reaction curing type heat curing type. Solvent-evaporating paint is a vehicle in which a solid resin of natural or synthetic is dissolved in a solvent to form a cured coating film only when the solvent evaporates.
So-called lacquer or varnish. Suitable for plastic moldings with low heat distortion temperature. Such solvent-evaporable paints include cellulose-based lacquers, vinyl-based lacquers, and acrylic-based lacquers. The self-reaction curable coating material includes an oxidative polymerization type, a multi-liquid reaction type and a moisture curing type. The heat-curable type is one that heats to cause a chemical cross-linking reaction of functional groups present in the coating vehicle,
There are alkyd resin paints, amino, alkyd resin paints, acrylic resin paints, and the like. In addition, there is a photocurable (ultraviolet curable) paint. The base material 10a of the housing made of a resin having transparency is preferably surface-treated on the coated surface before coating. Housing base material 1 made of transparent resin
By applying the surface treatment to 0a, it becomes possible to improve the adherence of the paint. The surface treatment includes chemical treatment and physical treatment. Examples of the chemical treatment include chemical treatment, coupling agent treatment, steam treatment, graft treatment, and electrochemical method. The physical treatment includes, for example, ultraviolet treatment, plasma treatment and ion irradiation.

用いることが適している。The adherence between the non-transparent covering member 13 and the base material 10a of the housing 10 made of a transparent resin is an important factor, but when the non-transparent covering member 13 is formed by painting, It is preferable to apply an undercoat to improve the adhesion to the film surface. It is suitable to use a primer as an undercoat when the base material 10a of the housing and the coating material are selected from materials that satisfy the required characteristics, but only when the adhesion is poor.

可能である。By coating the outer surface of the substrate 10a, the irregularities on the outer surface can be smoothed and the flow marks on the outer surface of the housing 10 can be covered. On the other hand, when the inner surface of the base material 10a is coated, there is almost no risk of peeling of the coating film by the non-transparent coating member 13. Further, in order to smooth the irregularities on the outer surface of the base material 10a of the housing 10, a surfacer may be coated on the outer surface. The non-transparent covering member 13 has a thickness of about 5 to 20 μm, and the thicker it is, the more smooth the unevenness can be, but the problem of tarmi of the coating also arises. Further, cracking of the coating film requires selection of a solvent for the coating, but can be prevented by annealing the base material 10a (molded product) of the housing 10 in advance.

果を述べる。These methods will be described with reference to the drawings. FIG. 4 shows at least the window portion 2 formed by molding the base material 10a of the housing 10 made of a resin having transparency, which is the above-described method.
A method of removing the masking member 14 by masking the portion corresponding to 0 with the masking member 14 and coating the outer surface and / or the inner surface of the base material 10a with the non-transparent coating member 13 will be described. Examples of the coating method include painting and printing. The masking member 14 only needs to mask at least a portion corresponding to the transparent window portion 20.
The surface to be coated is preferably subjected to the above-mentioned surface treatment from the viewpoint of adhesiveness. It may be coated on either the outer surface or the inner surface of the substrate 10a, or both. When the outer surface is covered, even the slender housing 10 can be masked from the outside and can be easily covered. Further, the housing 10 is usually made of a plastic molding, but the surface irregularities can be smoothed by coating. When coating the inner surface, peeling of the coating member 13 does not pose a problem in use as an electronic thermometer. The manufacturing process and quality assurance are easy without problems such as uneven painting and sagging. By coating the inner surface of the base material 10a, the application range is not narrowed by the material selection of the coating member 13 from the viewpoint of safety to the human body for armpits and mouth. Either the inner or outer surface of the covering member (or both)
Since the effects of the selection are common to the following methods, the effects of only the parts different from this method will be described below.

まりが向上する。FIG. 5 shows the above-mentioned method, in which the base material 10a of the housing 10 made of a transparent resin is molded, and the outer surface and / or the inner surface of the base material 10a of the housing 10 is coated with a resin. It is a figure which shows the method of coating with the transparent coating member 13, and peeling (removing) at least the portion corresponding to the window 20 with a laser or the like. The advantage of this method is that the coating process can be simplified. Moreover, since the covering member 13 is at least partially peeled (removed) corresponding to the window portion 2 by the laser,
Since there is no burr at the boundary portion 15 between the window portion 20 and the covering portion 13 (it is difficult), the aesthetic appearance is not spoiled and a post-process such as deburring is unnecessary. In FIG. 6, the portion corresponding to the window 20 is the convex portion 16 which is the above-described method.
The base material 10 of the housing 10 made of a transparent resin
It is a figure which shows the method of shape | molding a, covering the outer surface and / or inner surface of this housing with the non-transparent coating member 13, and scraping off the convex part 16. If the convex portion 16 of the present method is thicker (higher) than the covering portion 13, it can be easily implemented when the convex portion 16 is scraped off. The non-transparent covering member 13 is used to scrape off the convex portion 16.
Need only be removed and the substrate 10a is exposed on the surface. The effect of this method is that the coating process such as painting does not require any special device,
The yield in the coating process of the electronic thermometer having the elongated housing 10 is improved.
