　また、カバー部材２には、押し込み部１ｃに対応する位置に、スイッチの役割を示したりするための文字や記号が印刷、または文字抜き印刷されている。なお、ユーザが操作部１０を操作するときに、ユーザがカバー部２を押すことで、プレート１の押し込み部１ｃが押し込まれ、スイッチ３ａが押される。 Further, on the cover member 2, characters and symbols for indicating the role of the switch are printed or printed without characters at positions corresponding to the push-in portions 1c. In addition, when a user operates the operation part 10, when the user pushes the cover part 2, the pushing part 1c of the plate 1 is pushed in and the switch 3a is pushed.
　本発明の操作部１０は、押し込み部１ｃを有するプレート１をカバー部材２で覆うため、操作部１０と操作部１０が設けられたプロジェクタなどの電子機器の本体とが一体感のあるデザインをとなる。 Since the operation unit 10 of the present invention covers the plate 1 having the push-in unit 1c with the cover member 2, the operation unit 10 and a main body of an electronic device such as a projector provided with the operation unit 10 have a design with a sense of unity. Become.
　なお、文字や記号部分以外の発光させたくない場所は、例えば印刷をして、発光素子からの光を透過しないようにしている。 It should be noted that places where it is not desired to emit light other than characters and symbols are printed, for example, so as not to transmit light from the light emitting element.
　図６は、回路基板３とプレート１との間に配置される囲み部材５の概略斜視図である。この囲み部材５は、壁面に囲まれた囲み部５ａと、囲み部５ａの一部に沿って延びる遮光部５ｂとを有し、遮光性の材料からなる。囲み部材５は、第３の発光素子３ｄを囲み、遮光部５ｂで第２の発光素子３ｄと第２の発光素子３ｃとの間を区切るように配置される。つまり、囲み部５ａで、第４の発光領域Ｄを囲み、遮光部５ｂで、第３の発光領域Ｃと第４の発光領域Ｄとを区切っている。囲み部５ａと遮光部５ｂはそれぞれ回路基板３とカバー部材２とに接している。この囲み部材５は、各発光領域同士の間の隙間が小さい場合に用いる。 FIG. 6 is a schematic perspective view of the surrounding member 5 disposed between the circuit board 3 and the plate 1. The enclosing member 5 includes an enclosing portion 5a surrounded by a wall surface and a light shielding portion 5b extending along a part of the enclosing portion 5a, and is made of a light shielding material. The enclosing member 5 surrounds the third light emitting element 3d, and is arranged so as to separate the second light emitting element 3d and the second light emitting element 3c by the light shielding portion 5b. That is, the fourth light emitting region D is surrounded by the surrounding portion 5a, and the third light emitting region C and the fourth light emitting region D are separated by the light shielding portion 5b. The surrounding portion 5a and the light shielding portion 5b are in contact with the circuit board 3 and the cover member 2, respectively. The surrounding member 5 is used when the gap between the light emitting regions is small.
　本発明では、第１の発光領域Ａと第２の発光領域Ｂとの間に、半透明のリブ１ｄ、１ｅ、１ｆが設けられている。第２の発光領域Ｂの第２の発光素子３ｃで発光した照明光は、ベース部材４の外壁４ｄに向かって進み、外壁４ｄで反射する。そして、外壁４ｄで反射した照明光は、半透明のリブ１ｄ、１ｅ、１ｆに順に入射する。リブ１ｄ、１ｅ、１ｆに入射する照明光は、各リブへの入射と出射を繰り返す度に一部が屈折や拡散をする。なぜなら、各リブの間には隙間（空気）があり、各リブの材質の屈折率は空気の屈折率と異なるからである。また、リブ１ｄ、１ｅ、１ｆは半透明であるため、光が各リブの内部を通過するときにも一部が散乱する。そのため、外壁４ｄで反射し、リブ１ｄに向かった照明光は、リブや、リブとリブとの隙間を通過する度に減衰し、第１の発光領域Ａに到達しにくくなる。 In the present invention, translucent ribs 1d, 1e, and 1f are provided between the first light emitting region A and the second light emitting region B. The illumination light emitted from the second light emitting element 3c in the second light emitting region B travels toward the outer wall 4d of the base member 4 and is reflected by the outer wall 4d. And the illumination light reflected by the outer wall 4d injects into the translucent ribs 1d, 1e, and 1f in order. A part of the illumination light incident on the ribs 1d, 1e, and 1f is refracted and diffused every time the light enters and exits each rib. This is because there is a gap (air) between the ribs, and the refractive index of the material of each rib is different from the refractive index of air. Moreover, since the ribs 1d, 1e, and 1f are translucent, a part of them is scattered when light passes through the inside of each rib. For this reason, the illumination light reflected by the outer wall 4d and directed toward the rib 1d is attenuated each time it passes through the rib or the gap between the ribs, and does not easily reach the first light emitting region A.
　以上のように構成された操作部１０では、第１の発光領域Ａは、ベース部材４の壁部４ｃと、プレート１のリブ１ｄ、１ｅ、１ｆと、囲み部材５とによって囲まれている。また、第２の発光領域Ｂは、プレート１のリブ１ｄ、１ｅ、１ｆとベース部材４の壁部４ｆ及び外壁４ｄとで囲まれている。第３の発光領域Ｃは、囲み部材５の遮光部５ｂとベース部材４の壁部４ｆ及び外壁４ｄとで囲まれている。また、第４の発光領域Ｄは、囲み部材５で囲まれている。また、ベース部材４と囲み部材５は遮光性を有する材料からなる。そのため、本発明の操作部１０では、各発光領域で発光した照明光が他の領域に入り込むことがない。したがって、操作部１０において、意図しない発色が生じたり、意図しない領域が発光しているように見えたりすることが防止される。 In the operation unit 10 configured as described above, the first light emitting region A is surrounded by the wall 4c of the base member 4, the ribs 1d, 1e, and 1f of the plate 1 and the surrounding member 5. The second light emitting region B is surrounded by the ribs 1d, 1e, and 1f of the plate 1 and the wall portion 4f and the outer wall 4d of the base member 4. The third light emitting region C is surrounded by the light shielding portion 5b of the surrounding member 5, the wall portion 4f of the base member 4, and the outer wall 4d. The fourth light emitting region D is surrounded by the surrounding member 5. The base member 4 and the surrounding member 5 are made of a light-shielding material. Therefore, in the operation unit 10 of the present invention, the illumination light emitted from each light emitting region does not enter another region. Therefore, it is possible to prevent the unintended color from appearing on the operation unit 10 and the unintended area from appearing to emit light.
　また、プレート１は、リブ１ｄ、１ｅ、１ｆを含んだ状態で一体的に成形されるため、部品点数や製造工程が増加することがない。 In addition, since the plate 1 is integrally formed with the ribs 1d, 1e, and 1f included, the number of parts and the manufacturing process do not increase.
　なお、上記の実施形態の説明では、プレート１のリブ１ｄ、１ｅ、１ｆと、ベース部材４の壁部４ｃ、４ｆ及び外壁４ｄと、囲み部材５を用いて、各発光領域を囲んだ。しかしながら、すべての全ての発光領域を、２重、または３重以上のリブで囲むようにすることもできる。 In the description of the above embodiment, each light emitting region is surrounded by the ribs 1d, 1e, and 1f of the plate 1, the wall portions 4c and 4f and the outer wall 4d of the base member 4, and the surrounding member 5. However, all the light emitting regions can be surrounded by double or triple or more ribs.
　本発明の操作部１０は、プロジェクタなどの電子機器の操作部として使用できる。また、プレート１と、回路基板３と、ベース部材４とで１つの発光ユニット２０を構成してもよい。この発光ユニット２０は電子機器の操作部以外に使用することができ、さらに、照明器具として使用することも可能である。 The operation unit 10 of the present invention can be used as an operation unit of an electronic device such as a projector. The plate 1, the circuit board 3, and the base member 4 may constitute one light emitting unit 20. The light-emitting unit 20 can be used for other than the operation unit of the electronic device, and can also be used as a lighting fixture.
　以上、本発明の望ましい実施形態について提示し、詳細に説明したが、本発明は上記実施形態に限定されるものではなく、要旨を逸脱しない限り、さまざまな変更及び修正が可能であることを理解されたい。 Although the preferred embodiments of the present invention have been presented and described in detail above, the present invention is not limited to the above-described embodiments, and it is understood that various changes and modifications can be made without departing from the gist.
