FIG. 8 is a schematic sectional view showing a main part of a projector 210 according to a second embodiment of the present invention. The configuration of the projector device 210 according to the present embodiment is the same as that of the projector device 1 according to the above-described first embodiment.
Since the configuration is substantially the same as that of the project device 100, the following description focuses on the differences from the project device 100 according to the first embodiment, and the common components are denoted by the same reference numerals and the description is omitted. The project device 210 in the present embodiment includes:
Since the configuration of the front panel 230 is mainly different from that of the project apparatus 100 in the first embodiment,
The following description focuses on the configuration of 0.

FIG. 8 shows a state in which the front plate 230 is mounted on the bezel main body 160 of the projector device 210. FIG. 9 shows a state in which the front plate attaching member 170 is adhered to the front plate 230 shown in FIG. 8 with the adhesive tape 180. Referring to FIGS. 8 and 9, front plate 23 is used.
The configuration of 0 will be specifically described. First, as shown in FIG.
A front plate base 235 is formed at the center of the front plate 230. The front plate base 230 is formed of, for example, acrylic or polycarbonate, similarly to the front plate 130 of the first embodiment. As shown in FIG. 9, a border printing portion 232 serving as a blind printing portion is formed on the light source side of the front plate base 235 inside the projector device. Specifically, as shown in FIG. 9, the front plate base 235 is formed at regular intervals at four ends.

The border printing portion 23 thus formed
2, an adhesive portion 231 which is a contact portion is formed. The bonding portion 231 is a portion where the front plate attaching member 170 is arranged in FIG. This adhesive part 2
In FIG. 8, reference numeral 31 denotes a surface of the border printing portion 232, to which the adhesive tape 180 is attached. As shown in FIG. 8, an adhesive tape 180 is disposed on the adhesive portion 231, and the front plate attaching member 170 is adhered and fixed to the front plate 230. That is, as shown in FIG. 9, the front plate attaching member 170 is attached to the portion where the border printing portion 232 is applied. Therefore, the border printing portion 232 functions to prevent the front plate mounting member 170 to be attached from being seen through from outside the front plate 230.

Then, as shown in FIG. 9, an AR (Anti-R) is formed on the entire surface of the center of the front plate other than the border printing portion 232 provided on the front plate base 235, as shown in FIG.
An effect (anti-reflection) film 233 is attached. Therefore, this AR film 233
Is disposed so as to completely cover the transparent portion 234 (a portion surrounded by a two-dot chain line) of the front plate 230. This transparent part 2
Reference numeral 34 denotes a portion on which an image is projected. Also, this AR
By disposing the film 233 on the front plate 230, it is possible to prevent the contrast of the image projected on the surface of the front plate 230 from being lowered under external light.

The AR film 233 is also provided outside the front plate base 235 as shown in FIG. 8, and is disposed outside the front plate base 235 over the entire surface. Thus, the AR film 233 is attached to the front plate base 23.
By arranging on the both sides of 5, the contrast of the image projected on the surface of front plate 230 can be further prevented from being reduced under external light, and a function of making it easier for the user to see the image is exhibited. A method of manufacturing the front plate 230 configured as described above will be described below. First, a border printing portion 232 shown in FIG. 9 is formed by printing inside the front plate base 235 (light source side) shown in FIG. Then, outside the front plate base 235, the front plate base 235
An AR film 233 having the same size as that of is attached.

Next, an AR film 233 is attached to the inside of the front plate base 235 as shown in FIG. As described above, when the AR film 233 is attached to the inside of the front plate base 235, the AR film 233 is arranged only in the center of the front plate, and the border printing portion 232 formed outside the center of the front plate. Will not be placed. The border printing portion 232 is formed with the bonding portion 231 for bonding the front plate mounting member 170 as described above. Therefore, on the bonding portion 231,
The AR film 233 will not be disposed. By the way, conventionally, in order to further prevent the contrast of an image projected on the surface of the front plate from lowering under external light, AR processing is performed on the front plate. Was done in the process.

That is, a hard coat solvent having abrasion resistance is applied to the entire front and back surfaces of the extruded screen original plate, and then immersed in an AR solvent to perform an AR process on the front plate. Then, the above-described border printing has been performed on the front plate subjected to the AR processing. And
Place an adhesive tape etc. on the adhesive part on this border printing,
It has been bonded and fixed to the main body of the projector device.
Therefore, the area of the front plate where the adhesive tape is placed is A
This means that border printing is performed on top of the R processing. As described above, the printing on the AR process has a problem that the adhesion of the ink is extremely deteriorated, so that the adhesive force to the printed portion cannot be secured, and the fixing to the front plate becomes unstable. Also, even if the above-described border printing is first performed on the front plate, and then the AR processing is performed, the adhesion of the adhesive tape on the AR-shaped processing is extremely deteriorated in adhesive strength,
Fixing to the front plate becomes unstable.

However, in the present embodiment, as described above, the border printing portion 232 of the front plate 230 is performed first, and further, since the AR film 233 is not disposed in the area where the adhesive tape is disposed, the printing is performed. The adhesiveness of the ink does not deteriorate, and the adhesiveness of the adhesive tape does not deteriorate. Therefore, the front plate 230 and the front plate mounting member 170 can be bonded and fixed with sufficient adhesion. Therefore, the reliability of the projector device 210 is significantly improved. In addition, the portion where the AR film 233 is not disposed inside the front plate base 235 of the front plate 230 is not a portion that affects the projected image. Therefore, there is no problem that the contrast of an image under external light is reduced due to the absence of the AR film 233. Furthermore, since the printing is performed on the light source side instead of the observation side, the appearance can be kept extremely clean.

The front plate 230 manufactured as described above is bonded to the front plate mounting member 170 with the adhesive tape 180 as described above, and is attached to the bezel body 160 of the projector 210 as shown in FIG. Fixed. Further, the projector device 210 is formed through a predetermined manufacturing process for the projector device 210.

The configuration of each of the above embodiments can be partially omitted or changed to another arbitrary combination not described above.
