摘要： PROBLEM TO BE SOLVED: To provide a screen which can suppress the occurrence of visual field missing, by disposing concave parts in positions in which projection light can be reflected in an appropriate state without shielding the projection light.
SOLUTION: By disposing first and second supplementary lines Ls1 and Ls2, the projection light PL can be made to be incident onto the reflective films RS of the first and third concave parts 20a and 20c, even when the incident angle of the projection light PL onto the screen 1 is large. Further, by making the number of fourth concave parts 20d in the second supplementary line Ls2 larger than that of third concave parts 20c in a second main line Lm2 in a second area AR2, the projection light PL can be prevented from being shielded by protrusions even when the incident angle of the projection light PL becomes large. Accordingly, the visual field missing can be reduced. Besides, the projection light PL is efficiently made to be incident onto the reflective film RS of each of the third concave parts 20c, and thereby the brightness of the screen 1 can be enhanced.

摘要翻译：要解决的问题：为了提供能够抑制视场缺失的发生的画面，通过将投影光能够以适当的状态反射的位置设置凹部而不屏蔽投影光。解决方案：通过配置第一和第二辅助线Ls1和Ls2，即使投影的入射角度也可以使投影光PL入射到第一和第三凹部20a和20c的反射膜RS上，屏幕1上的光PL很大。此外，通过使第二辅助线Ls2中的第四凹部20d的数量比第二区域AR2中的第二主线Lm2中的第三辅助线Ls2的第四凹部20d的数量大于第二主线Lm2的第四凹部20d的数量，也能够防止突起等被屏蔽当投影光PL的入射角变大时。因此，可以减少视野缺失。此外，投射光PL被有效地入射到每个第三凹部20c的反射膜RS上，从而可以提高屏幕1的亮度。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a screen capable of improving contrast of a projection image in a bright room or the like by reducing an influence due to reflected external light.
SOLUTION: A part of component of incident external light OL is reflected on a light absorbing surface AS without being absorbed. By reflecting the external light reflection light OR reflected without being absorbed on the light absorbing surface AS on a light reflection surface RS, the external light reflection light OR is made incident to the light absorbing surface AS again and is absorbed on the light absorbing surface AS again. Also thereby, reflected remaining light RR further gets to an extremely small amount. Moreover, the direction of the remaining light RR is turned to upward through twice reflections on the light absorbing surface AS and inner surface reflection on the light reflection surface RS and, therefore, deviates from the observer's side of the screen 10.

摘要翻译：要解决的问题：通过减少由反射的外部光引起的影响，提供能够改善亮室等中的投影图像的对比度的屏幕。解决方案：入射外部光OL的分量的一部分在光吸收表面AS上反射而不被吸收。通过反射外部光反射光OR反射而不被光反射面RS上的吸光面AS吸收，外部光反射光OR再次入射到光吸收表面AS，并被吸收在光吸收表面AS上再次。因此，反射剩余光RR进一步变得极小量。此外，剩余光RR的方向通过光吸收表面AS上的两次反射和光反射表面RS上的内表面反射而变为向上，因此偏离屏幕10的观察者侧。

摘要： PROBLEM TO BE SOLVED: To more accurately detect rotary direction and angle without being affected by aging. SOLUTION: Since both of the signal transition timing of a first waveform- shaping signal SSUM and that of a second waveform-shaping signal SDIF are used to refer to a signal level mutually when turning a rotary bezel and inputting information, a position detection precision can be improved and the rotary position of the rotary bezel can be detected for securing inputting information. Also, since the first waveform-shaping signal SSUM and the second waveform- shaping signal SDIF that are related each other are mutually referred to, the influence of aging of sensor units 32 and 33 can be reduced.
