　そこで、本発明の目的は、パネルの塗装を容易にしつつ、照明用光源の光が表示部以外の部分に漏洩するのを抑止することのできる表示装置を提供する。 Therefore, an object of the present invention is to provide a display device that can prevent the light of the light source for illumination from leaking to a portion other than the display portion while facilitating painting of the panel.
　この目的を達成するために、本発明の表示装置は、照明用光源が実装された回路基板と、透光性を有して前記照明用光源により後方から照明されることが可能な表示部を含む表示パネル部と、この表示パネル部から後方へ離間した位置に前記回路基板を保持する基板保持部とを有するパネルと、前記回路基板の前側面と前記表示パネル部の後側面との間に介在する遮光部材とを備え、前記遮光部材は、前記表示パネル部側から前記回路基板側に向かって延びて前記照明用光源から前記表示部に至る光路を囲む筒状を有するとともに軸方向両側に前端面および後端面を有する遮光部材本体と、この遮光部材本体の前端面の少なくとも一部の領域に当該前端面に沿って延びるように形成され、当該前端面の幅よりも小さい幅を有するとともに当該前端面から前記表示パネル部側に向かって突出する突出部とを有し、前記遮光部材本体は、その前端面から後端面までの距離に相当する軸方向寸法が、前記表示パネル部の後側面から前記基板保持部により保持された状態の前記回路基板の前側面までの離間距離よりも小さい形状を有し、前記突出部は、前記遮光部材本体の後端面が前記回路基板の前側面に接触した状態でこの遮光部材本体の前端面と前記表示パネル部の後側面との間に形成される隙間の寸法よりも大きな突出寸法を有し、これらの寸法同士の差に相当する分だけ圧縮変形した状態で前記表示パネル部の後側面に密着することが可能な形状を有するものである。 In order to achieve this object, a display device according to the present invention includes a circuit board on which an illumination light source is mounted, and a display unit that is translucent and can be illuminated from behind by the illumination light source.

The light blocking member main body 32 is arranged such that the walls 32a, 32b, 32c, and 32d surround the light path of the LED 50c on the circuit board 40, thereby preventing the light of the LED 50c from leaking outside the light blocking member 30. To do. In a state where the light shielding member 30 is inserted inside the light shielding member guide wall 16, the upper wall 32c is disposed at a boundary portion between the first operation knob 20 and the display unit 12, and the lower wall 32d is disposed in the first wall. 2 Arranged at the boundary between the operation knob 120 and the display unit 12. The light shielding member main body 32 is made of polycarbonate, for example.
　前記遮光部材本体３２の軸方向寸法すなわち遮光部材本体３２の前端面から後端面までの距離は、回路基板４０が前記パネル２に保持された状態におけるこの回路基板４０の前側面４０ａから前記表示パネル部１０の後側面１０ａまでの離間距離よりも小さい。具体的には、遮光部材３０が表示パネル部１０と回路基板４０との間に取り付けられた状態において、前記遮光部材本体３２の各部位の軸方向寸法は、この遮光部材本体３２の各部位と対向する回路基板４０の前側面１０ａの各部位から表示パネル部１０の後側面１０ａの各部位までの離間距離よりもそれぞれ小さい。例えば、図８において、遮光部材本体３２の下壁３２ｄの軸方向寸法Ｌ１は、回路基板４０の前側面１０ａのうちのこの下壁３２ｄと対向する部位から表示パネル部１０の後側面１０ａのうちのこの下壁３２ｄと対向する部位までの離間距離Ｗ１よりも小さい。また、遮光部材本体３２の上壁３２ｃの軸方向寸法Ｌ２は、回路基板４０の前側面１０ａのうちのこの上壁３２ｃと対向する部位から表示パネル部１０の後側面１０ａのうちのこの上壁３２ｃと対向する部位までの離間距離Ｗ２よりも小さい。 The axial dimension of the light shielding member main body 32, that is, the distance from the front end surface to the rear end surface of the light shielding member main body 32, is determined from the front side surface 40a of the circuit board 40 in the state where the circuit board 40 is held by the panel 2 to the display panel. It is smaller than the separation distance to the rear side surface 10a of the part 10. Specifically, in the state where the light shielding member 30 is attached between the display panel unit 10 and the circuit board 40, the axial dimension of each part of the light shielding member main body 32 is the same as each part of the light shielding member main body 32. The distance from each part of the front side surface 10a of the circuit board 40 facing each other to each part of the rear side surface 10a of the display panel unit 10 is smaller than each. For example, in FIG. 8, the axial dimension L1 of the lower wall 32d of the light shielding member main body 32 is from the portion of the front side surface 10a of the circuit board 40 facing the lower wall 32d to the rear side surface 10a of the display panel unit 10. It is smaller than the separation distance W1 to the part facing the lower wall 32d. The axial dimension L2 of the upper wall 32c of the light shielding member main body 32 is such that the upper wall of the rear side surface 10a of the display panel unit 10 from the portion of the front side surface 10a of the circuit board 40 facing the upper wall 32c. It is smaller than the separation distance W2 to the part facing 32c.
　ここで、前記回路基板４０の前側面４０ａから表示パネル部１０の後側面１０ａまでの離間距離は、回路基板４０をパネル２に取り付ける際の取り付け誤差等に伴ってばらつく。そのため、例えば、前記遮光部材本体３２の軸方向寸法を前記離間距離と同じ寸法に設定しておくと、この離間距離が短くなる方向にばらついた場合には前記遮光部材本体３２を回路基板４０と表示パネル部１０との間に配置できなくなる。これに対して、本表示装置１では、前記遮光部材本体３２の軸方向寸法が前記離間距離よりも小さいことで、遮光部材本体３２は確実に回路基板４０と表示パネル部１０との間に配置される。 Here, the separation distance from the front side surface 40a of the circuit board 40 to the rear side surface 10a of the display panel unit 10 varies with an attachment error or the like when the circuit board 40 is attached to the panel 2. Therefore, for example, if the axial direction dimension of the light shielding member main body 32 is set to the same dimension as the separation distance, the light shielding member main body 32 is connected to the circuit board 40 when the separation distance varies in the direction of shortening. It becomes impossible to arrange | position between the display panel parts 10. FIG. On the other hand, in the display device 1, since the axial dimension of the light shielding member main body 32 is smaller than the separation distance, the light shielding member main body 32 is reliably disposed between the circuit board 40 and the display panel unit 10. Is done.
　前記リブ状微小突起３９は、前記遮光部材本体３２の前端面から前方に突出する微小突起である。本表示装置１では、前記遮光部材本体３２の４つの側壁のうち上壁３２ｃの前端面３３ｃと下壁３２ｄの前端面３３ｄとにそれぞれリブ状微小突起３９ｃ、３９ｄが設けられている。これらリブ状微小突起３９ｃ、３９ｄは、前記上壁３２ｃの前端面３３ｃおよび下壁３２ｄの前端面３３ｄに沿ってそれぞれ左右に延びている。これらリブ状微小突起３９ｃ、３９ｄは、圧縮変形しやすいように上壁３２ｃおよび下壁３２ｄの幅よりも小さい幅を有しており、前記上壁３２ｃの前端面３３ｃおよび下壁３２ｄの前端面３３ｄの各外側端に沿って設けられている。また、これらリブ状微小突起３９ｃ、３９ｄは、前方に向かうほどその幅が小さくなる形状を有している。 The rib-like microprojections 39 are microprojections that protrude forward from the front end surface of the light shielding member main body 32. In the display device 1, rib- like microprojections 39 c and 39 d are provided on the front end surface 33 c of the upper wall 32 c and the front end surface 33 d of the lower wall 32 d among the four side walls of the light shielding member main body 32. These rib-shaped minute protrusions 39c and 39d extend to the left and right along the front end surface 33c of the upper wall 32c and the front end surface 33d of the lower wall 32d, respectively. These rib-shaped microprotrusions 39c and 39d have a width smaller than the width of the upper wall 32c and the lower wall 32d so as to be easily deformed by compression, and the front end face 33c of the upper wall 32c and the front end face of the lower wall 32d. 33d is provided along each outer end. Moreover, these rib-shaped microprotrusions 39c and 39d have a shape in which the width decreases toward the front.
　前記下壁３２ｄに設けられたリブ状微小突起３９ｄの前方への突出寸法は、前記遮光部材本体３２の後端面３２ｅが前記回路基板４０の前側面４０ａに接触した状態において前記下壁３２ｄの前端面３３ｄと表示パネル部１０の後側面１０ａとの間に形成される隙間の寸法よりも大きい。すなわち、前記リブ状微小突起３９ｄの前方への突出寸法ｔ（図７参照）は、回路基板４０が前記パネル２に保持された状態において、この回路基板４０の前側面４０ａから表示パネル部１０の後側面１０ａまでの離間距離Ｗ１と遮光部材本体３２（下壁３２ｄ）の軸方向寸法Ｌ１との差Ｗ１－Ｌ１よりも大きい。同様に、前記上壁３２ｃに設けられたリブ状微小突起３９ｃの前方への突出寸法は、前記遮光部材本体３２の後端面３２ｅが前記回路基板４０の前側面４０ａに接触した状態において前記上壁３２ｃの前端面３３ｃと表示パネル部１０の後側面１０ａとの間に形成される隙間の寸法よりも大きい。すなわち、リブ状微小突起３９ｃの前方への突出寸法は、回路基板４０が前記パネル２に保持された状態におけるこの回路基板４０の前側面４０ａから表示パネル部１０の後側面１０ａまでの離間距離と遮光部材本体３２（上壁３２ｃ）の軸方向寸法との差よりも大きい。 The forward projecting dimension of the rib-like microprojections 39d provided on the lower wall 32d is such that the front end of the lower wall 32d is in a state where the rear end surface 32e of the light shielding member body 32 is in contact with the front side surface 40a of the circuit board 40. It is larger than the dimension of the gap formed between the surface 33 d and the rear side surface 10 a of the display panel unit 10. That is, the protruding dimension t (see FIG. 7) of the rib-shaped minute protrusion 39d is determined from the front side surface 40a of the circuit board 40 when the circuit board 40 is held by the panel 2. It is larger than the difference W1−L1 between the separation distance W1 to the rear side surface 10a and the axial dimension L1 of the light shielding member main body 32 (lower wall 32d). Similarly, the forward projecting dimension of the rib-like minute protrusion 39c provided on the upper wall 32c is such that the upper wall in the state where the rear end surface 32e of the light shielding member body 32 is in contact with the front side surface 40a of the circuit board 40. It is larger than the size of the gap formed between the front end surface 33c of 32c and the rear side surface 10a of the display panel unit 10. In other words, the forward projecting dimension of the rib-shaped minute protrusion 39c is the distance from the front side surface 40a of the circuit board 40 to the rear side surface 10a of the display panel unit 10 in a state where the circuit board 40 is held by the panel 2. It is larger than the difference from the axial dimension of the light shielding member main body 32 (upper wall 32c).
　前記リブ状微小突起３９ｃ、３９ｄは、弾性変形可能な部材からなる。この実施形態では、両リブ状微小突起３９ｃ、３９ｄが遮光部材本体３２と一体にＡＢＳ樹脂により形成されている。これらリブ状微小突起３９ｃ、３９ｄは、遮光部材３０が前記遮光部材ガイド壁１６内に挿入された状態で回路基板４０がパネル２に取り付けられた際に、遮光部材本体３２の前端面３３ｃ、３３ｄと表示パネル部１０の後側面１０ａとの間で圧縮変形する。これらリブ状微小突起３９ｃ、３９ｄは、前記のような遮光部材本体３２の前端面３３ｃ、３３ｄと表示パネル部１０の後側面１０ａとの間に形成される隙間よりも大きな突出寸法からこの隙間の寸法まで圧縮変形する。そして、これらリブ状微小突起３９ｃ、３９ｄは、表示パネル部１０の後側面１０ａに密着し、図９に示すように、前記遮光部材本体３２の前端面３３ｃ、３３ｄと表示パネル部１０の後側面１０ａとの間の隙間をそれぞれ密閉する。 The rib- like minute projections 39c and 39d are made of a member that can be elastically deformed. In this embodiment, both rib- like microprojections 39c and 39d are formed of ABS resin integrally with the light shielding member main body 32. The rib-shaped minute projections 39c and 39d are formed on the front end surfaces 33c and 33d of the light shielding member main body 32 when the circuit board 40 is attached to the panel 2 with the light shielding member 30 inserted into the light shielding member guide wall 16. And the rear side surface 10a of the display panel unit 10 are compressed and deformed. These rib- like minute projections 39c and 39d are formed in the gaps from the projecting dimensions larger than the gaps formed between the front end surfaces 33c and 33d of the light shielding member body 32 and the rear side surface 10a of the display panel unit 10 as described above. Compressive deformation to dimensions. These rib-shaped minute protrusions 39c and 39d are in close contact with the rear side surface 10a of the display panel unit 10, and as shown in FIG. 9, the front end surfaces 33c and 33d of the light shielding member body 32 and the rear side surface of the display panel unit 10 are provided. Each of the gaps between 10a is sealed.
　前述のように、遮光部材本体３２の軸方向寸法は回路基板４０の前側面４０ａから表示パネル部１０の後側面１０ａまでの離間距離よりも小さい。そのため、もし前記リブ状微小突起３９ｃ、３９ｄがなければ、従来装置と同様に、遮光部材本体３２と表示パネル部１０との間に隙間が生じて、この隙間からＬＥＤ５０ｃの光が外部に漏洩するおそれがある。しかも、この隙間の寸法は前記離間距離のばらつき等に伴ってばらつき、さらに大きくなるおそれがある。これに対して、本表示装置１では、前記遮光部材本体３２の前端面３３ｃ、３３ｄから前方に突出するリブ状微小突起３９が、前記隙間の寸法に応じて圧縮変形して表示パネル部１０の後側面１０ａに密着することで、前記隙間から前記ＬＥＤ５０ｃの光が外部に漏えいするのを抑制する。特に、前記リブ状微小突起３９ｃ、３９ｄは、表示部１２と第１操作ノブ２０との境界部分に配置された上壁３２ｃおよび表示部１２と第２操作ノブ１２０との境界部分に配置された下壁３２ｄとの境界部分にそれぞれ設けられている。そのため、前記ＬＥＤ５０ｃの光が前記第１操作ノブ２０、１２０側に漏洩するのが効果的に抑制される。 As described above, the axial dimension of the light shielding member main body 32 is smaller than the separation distance from the front side surface 40a of the circuit board 40 to the rear side surface 10a of the display panel unit 10. For this reason, if the rib- like microprojections 39c and 39d are not provided, a gap is formed between the light shielding member main body 32 and the display panel unit 10 as in the conventional device, and the light of the LED 50c leaks to the outside from this gap. There is a fear. In addition, the size of the gap varies with the variation in the separation distance, and may become larger. On the other hand, in the display device 1, the rib-like minute protrusions 39 protruding forward from the front end surfaces 33 c and 33 d of the light shielding member main body 32 are compressed and deformed according to the size of the gap, and By closely contacting the rear side surface 10a, the light of the LED 50c is prevented from leaking outside through the gap. In particular, the rib-shaped minute protrusions 39c and 39d are disposed at the boundary between the display unit 12 and the second operation knob 120 and the upper wall 32c disposed at the boundary between the display unit 12 and the first operation knob 20. Each is provided at a boundary portion with the lower wall 32d. Therefore, the leakage of the light from the LED 50c to the first operation knobs 20 and 120 is effectively suppressed.
　なお、本発明では、遮光部材本体３２の具体的な形状を問わないが、前記遮光部材本体３２には、被仮係止突起３４、第１離脱阻止部３６ａおよび第２離脱阻止部３６ｂが設けられている。前記被仮係止突起３４は、遮光部材本体３０をパネル２に仮係止するための部分である。前記第１離脱阻止部３６ａおよび第２離脱阻止部３６ｂは、第１操作ノブ２０および第２操作ノブ１２０のパネル２からの離脱をそれぞれ阻止するための部分である。 In the present invention, the specific shape of the light shielding member main body 32 is not limited, but the light shielding member main body 32 is provided with a provisionally locked protrusion 34, a first separation preventing portion 36a, and a second separation preventing portion 36b. It has been. The temporarily locked protrusion 34 is a portion for temporarily locking the light shielding member main body 30 to the panel 2. The first detachment prevention part 36a and the second detachment prevention part 36b are parts for preventing the first operation knob 20 and the second operation knob 120 from detaching from the panel 2, respectively.
　前記被仮係止突起３４は、図１０に示すように、前記遮光部材本体３２の下壁３２ｄから下側に突出している。遮光部材本体３２が前記遮光部材ガイド壁１６の内側に挿入された状態において、この被仮係止突起３４は前記仮係止孔１６ａに挿入される。この挿入により、遮光部材３０は、遮光部材ガイド壁１６の内側に仮係止されて後方に脱落するのが回避される。 As shown in FIG. 10, the provisionally locked protrusion 34 protrudes downward from the lower wall 32 d of the light shielding member main body 32. In a state where the light shielding member main body 32 is inserted inside the light shielding member guide wall 16, the provisionally engaged projection 34 is inserted into the temporary engaging hole 16a. This insertion prevents the light shielding member 30 from being temporarily locked inside the light shielding member guide wall 16 and falling off rearward.
　前記第１離脱阻止部３６ａは、前記遮光部材本体３２の上壁３２ｃの後端部から上方すなわち前記第１ノブ保持壁１７に保持された前記第１操作ノブ２０側に突出して、前記表示パネル部１０と略平行に延びる形状を有している。この第１離脱阻止部３６ａは、図２に示すように、前記第１操作ノブ２０が前記第１ノブ保持壁１７内に挿入されてこの第１ノブ保持壁１７に保持された状態で、この第１操作ノブ２０の後端部に後方から当接可能な位置に設けられている。そして、この第１離脱阻止部３６ａは、前記当接によって前記第１操作ノブ２０が後方すなわち前記表示パネル部１０から離間する方向に移動するのを規制する。 The first separation preventing portion 36a protrudes upward from the rear end portion of the upper wall 32c of the light shielding member body 32, that is, toward the first operation knob 20 held by the first knob holding wall 17, and the display panel It has a shape extending substantially parallel to the portion 10. As shown in FIG. 2, the first detachment preventing portion 36 a is in a state in which the first operation knob 20 is inserted into the first knob holding wall 17 and held by the first knob holding wall 17. The first operation knob 20 is provided at a position where it can come into contact with the rear end portion of the first operation knob 20 from behind. The first detachment preventing portion 36a restricts the first operation knob 20 from moving rearward, that is, away from the display panel portion 10 by the contact.
　同様に、前記第２離脱阻止部３６ｂは、前記遮光部材本体３２の下壁３２ｄの後端部から下方に突出して前記表示パネル部１０と略平行に延びる形状を有している。この第２離脱阻止部３６ｂは、第２操作ノブ１２０の後端部に当接して前記第２操作ノブ１２０が後方すなわち前記表示パネル部１０から離間する方向に移動するのを規制する。 Similarly, the second separation preventing portion 36b has a shape that protrudes downward from the rear end portion of the lower wall 32d of the light shielding member body 32 and extends substantially parallel to the display panel portion 10. The second disengagement preventing portion 36b abuts on the rear end portion of the second operation knob 120 and restricts the second operation knob 120 from moving backward, that is, in a direction away from the display panel portion 10.
　なお、前記第１離脱阻止部３６ａおよび第２離脱阻止部３６ｂは、前記第１操作ノブ２０と第２操作ノブ１２０が前記表示パネル部１０に近接する方向にスライドした状態ではこれら第１操作ノブ２０および第２操作ノブ１２０の各後端部と離間する位置に設けられており、この第１操作ノブ２０および第２操作ノブ１２０の表示パネル部１０と接離する方向のストロークを許容しつつ前記表示パネル部１０からの離脱を阻止する。 The first separation preventing portion 36a and the second separation preventing portion 36b are configured so that the first operation knob 20 and the second operation prevention portion 36b are in a state in which the first operation knob 20 and the second operation knob 120 are slid in the direction close to the display panel unit 10. 20 and the second operation knob 120 are provided at positions separated from the respective rear end portions, while allowing the stroke of the first operation knob 20 and the second operation knob 120 to come in contact with and away from the display panel 10. Detachment from the display panel unit 10 is prevented.
　このように、本表示装置１では、前記ＬＥＤ５０ｃの光路を囲み前記表示部１２を適切に照明するために設けられる遮光部材３０を利用して、前記第１操作ノブ２０および第２操作ノブ１２０の表示パネル部１０からの離脱が阻止されている。 As described above, in the present display device 1, the first operation knob 20 and the second operation knob 120 are used by using the light shielding member 30 provided to surround the optical path of the LED 50 c and appropriately illuminate the display unit 12. Detachment from the display panel unit 10 is prevented.
　次に、前記のように構成された各部品を組み付けて前記表示装置１を製造するための具体的な方法について説明する。 Next, a specific method for manufacturing the display device 1 by assembling the components configured as described above will be described.
　まず、前記上側突出壁４と下側突出壁１０４と表示パネル部１０とを有するパネル２を製造する。この工程では、透光性を有する部材で表示パネル部１０を成形した後、遮光性を有する塗料で前記表示部１２以外の部分を塗装することで、前記表示部１２が形成された表示パネル部１０を製造する。 First, the panel 2 having the upper protruding wall 4, the lower protruding wall 104, and the display panel unit 10 is manufactured. In this step, after the display panel unit 10 is formed with a light-transmitting member, the display panel unit on which the display unit 12 is formed is formed by painting a portion other than the display unit 12 with a light-shielding paint. 10 is manufactured.
　また、前記遮光部材３０を製造する。この工程では、遮光性を有する部材で前記遮光部材本体３２とリブ状微小突起３９ｃ、３９ｄとを一体に成形する。ここで、パネルと遮光部材とが分割されておらずこれらが一体となった従来のパネルを製造する場合には、透光性を有する部材でパネル全体を成形した後、前記遮光部材を含む前記表示部以外の部分を遮光性を有する塗料で塗装する必要がある。この場合には、遮光部材が一体となっていることでパネルが複雑な形状を有しており塗装に手間がかかる。これに対して、本表示装置１では、前記表示パネル部１０と遮光部材３０とが分割されており表示パネル部１０の形状が簡素化されているので、塗装が容易となり作業効率が向上する。 Further, the light shielding member 30 is manufactured. In this step, the light shielding member main body 32 and the rib-shaped minute projections 39c and 39d are integrally formed of a member having a light shielding property. Here, in the case of manufacturing a conventional panel in which the panel and the light shielding member are not divided and integrated with each other, after the entire panel is molded with a light-transmitting member, the light shielding member is included. It is necessary to paint a portion other than the display portion with a paint having a light shielding property. In this case, since the light shielding member is integrated, the panel has a complicated shape, and it takes time to paint. On the other hand, in this display device 1, since the display panel unit 10 and the light shielding member 30 are divided and the shape of the display panel unit 10 is simplified, painting is facilitated and work efficiency is improved.
　次に、前記第１操作ノブ２０および第２操作ノブ１２０を、後方から前記第１ノブ保持壁１７および第２ノブ保持壁１１７内にそれぞれ挿入する。そして、前記第１操作ノブ２０および第２操作ノブ１２０をこれら前記第１ノブ保持壁１７および第２ノブ保持壁１１７によって前記表示パネル部１０の後側に保持する。 Next, the first operation knob 20 and the second operation knob 120 are inserted into the first knob holding wall 17 and the second knob holding wall 117 from the rear, respectively. The first operation knob 20 and the second operation knob 120 are held behind the display panel unit 10 by the first knob holding wall 17 and the second knob holding wall 117.
　次に、前記遮光部材３０を後方から前記遮光部材ガイド壁１６内に挿入する。そして、前記遮光部材３０の被仮係止突起３４を前記遮光部材ガイド壁１６の仮係止孔１６ａに挿入して、遮光部材３０を表示パネル部１０の後側に仮係止する。このとき、前記第１離脱阻止部３６ａは、前記第１操作ノブ２０の後端部と対向する位置に配置される。また、前記第２離脱阻止部３６ａは、前記第２操作ノブ１２０の後端部と対向する位置に配置される。 Next, the light shielding member 30 is inserted into the light shielding member guide wall 16 from behind. Then, the temporarily locked protrusion 34 of the light shielding member 30 is inserted into the temporary locking hole 16 a of the light shielding member guide wall 16 to temporarily lock the light shielding member 30 to the rear side of the display panel unit 10. At this time, the first separation preventing portion 36a is disposed at a position facing the rear end portion of the first operation knob 20. Further, the second disengagement preventing portion 36 a is disposed at a position facing the rear end portion of the second operation knob 120.
　この状態において、前記第１操作ノブ２０にこの第１操作ノブ２０を後方すなわち表示パネル部１０から離脱する方向に移動させる力が働いたとしても、この第１操作ノブ２０の後端部が前記第１離脱阻止部３６ａと当接することで、この第１操作ノブ２０の表示パネル部１０からの離脱は阻止される。同様に、前記第２操作ノブ１２０にこの第２操作ノブ１２０を後方すなわち表示パネル部１０から離脱する方向に移動させる力が働いたとしても、この第２操作ノブ１２０の後端部が前記第２離脱阻止部１３６ａ当接することで、この第２操作ノブ１２０の表示パネル部１０からの離脱は阻止される。 In this state, even if a force is applied to the first operation knob 20 to move the first operation knob 20 rearward, that is, in a direction to detach from the display panel unit 10, the rear end portion of the first operation knob 20 is By coming into contact with the first detachment preventing portion 36a, the detachment of the first operation knob 20 from the display panel portion 10 is prevented. Similarly, even if a force is applied to the second operation knob 120 to move the second operation knob 120 rearward, that is, in a direction away from the display panel unit 10, the rear end portion of the second operation knob 120 is connected to the second operation knob 120. 2 Abutment of the second operation knob 120 from the display panel unit 10 is prevented by abutting on the disengagement prevention unit 136a.
　このようにして、本方法では、前記遮光部材３０の被仮係止突起３４と前記遮光部材ガイド壁１６の仮係止孔１６ａとの係合により、前記遮光部材３０に加えて前記第１操作ノブ２０および第２操作ノブ１２０が表示パネル部１０の後側に拘束される。 Thus, in this method, in addition to the light shielding member 30, the first operation is performed by the engagement between the temporarily engaged projection 34 of the light shielding member 30 and the temporary locking hole 16 a of the light shielding member guide wall 16. The knob 20 and the second operation knob 120 are restrained on the rear side of the display panel unit 10.
　次に、前記ＬＥＤ５０ｃ等を実装しておいた回路基板４０を前記上側保持部４ａおよび下側保持部１０４ａに取り付ける。この工程では、まず、前記ＬＥＤ５０ｃが前記表示部１２とそれぞれ対向し前記遮光部材本体３２の各壁３２ａ、３２ｂ、３２ｃ、３２ｄで囲まれた領域に収容されるとともに、前記スイッチ素子６０、１６０が前記第１操作ノブ２０および第２操作ノブ１２０とそれぞれ対向するように、回路基板４０を上側保持部４ａと下側保持部１０４ａの後端面に沿って配置する。そして、基板係止用ねじ４ｃ、１０４ｃを、回路基板４０の前記被係止用孔４１、１４１に挿通させた後、前記上側保持部４ａおよび下側保持部１０４ａの係止用ネジ孔に締結する。このとき、回路基板４０は前記遮光部材本体３２の後端面３２ｅを前方に押圧し、押圧された遮光部材本体３２の前端面３３ｃ、３３ｄによってリブ状微小突起３９ｃ、３９ｄが表示パネル部１０の後側面１０ａに押し付けられる。これにより、リブ状微小突起３９ｃ、３９ｄは表示パネル部１０と遮光部材本体３２との離間距離に応じて圧縮変形して表示パネル部１０の後側面１０ａに密着する。 Next, the circuit board 40 on which the LEDs 50c and the like are mounted is attached to the upper holding part 4a and the lower holding part 104a. In this step, first, the LED 50c is housed in a region surrounded by the walls 32a, 32b, 32c, and 32d of the light shielding member main body 32 so as to face the display unit 12, and the switch elements 60 and 160 are disposed. The circuit board 40 is disposed along the rear end surfaces of the upper holding portion 4a and the lower holding portion 104a so as to face the first operation knob 20 and the second operation knob 120, respectively. Then, after the board locking screws 4c and 104c are inserted into the locked holes 41 and 141 of the circuit board 40, they are fastened to the locking screw holes of the upper holding part 4a and the lower holding part 104a. To do. At this time, the circuit board 40 presses the rear end surface 32e of the light shielding member main body 32 forward, and the rib-shaped minute protrusions 39c and 39d are formed behind the display panel unit 10 by the front end surfaces 33c and 33d of the pressed light shielding member main body 32. Pressed against the side surface 10a. Thereby, the rib-shaped minute protrusions 39 c and 39 d are compressed and deformed according to the separation distance between the display panel unit 10 and the light shielding member main body 32 and are brought into close contact with the rear side surface 10 a of the display panel unit 10.
　このようにして、本表示装置１では、前記パネル２と回路基板４０との間の距離にばらつきがあっても、リブ状微小突起３９ｃ、３９ｄの圧縮変形によりこのばらつきが吸収され表示パネル部１０と遮光部材本体３２との隙間が密閉される。 In this manner, in the present display device 1, even if there is a variation in the distance between the panel 2 and the circuit board 40, the variation is absorbed by the compression deformation of the rib- like minute protrusions 39c and 39d, and the display panel unit 10 And the light shielding member main body 32 are sealed.
　ここで、リブ状微小突起３９ｃ、３９ｄは、遮光部材本体３２のうち上壁３２ｃと下壁３２ｄとにのみ設けられている。そのため、遮光部材本体３２の前端面全てすなわち右壁３２ａと左壁３２ｂとにもリブ状微小突起が設けられている場合に比べて、リブ状微小突起３９ｃ、３９ｄに圧縮応力が集中する分、これらリブ状微小突起３９ｃ、３９ｄは容易に圧縮変形する。また、リブ状微小突起３９ｃ、３９ｄは、その幅が前方に向かうほどすなわち先端に向かうほど小さくなっており、このこともリブ状微小突起３９ｃ、３９ｄの変形を促進する。 Here, the rib- like minute protrusions 39c and 39d are provided only on the upper wall 32c and the lower wall 32d of the light shielding member main body 32. Therefore, compared with the case where rib-like microprojections are provided on all the front end surfaces of the light shielding member main body 32, that is, the right wall 32a and the left wall 32b, the compressive stress is concentrated on the rib- like microprojections 39c, 39d. These rib- like minute projections 39c and 39d are easily compressed and deformed. Further, the rib- like microprotrusions 39c and 39d become smaller toward the front, that is, toward the tip, and this also promotes deformation of the rib- like microprotrusions 39c and 39d.
　以上のように組みつけられた表示装置１では、前記ＬＥＤ５０ｃが前記遮光部材本体３２の各壁３２ａ、３２ｂ、３２ｃ、３２ｄで囲まれた領域に収容されるとともに、リブ状微小突起３９ｃ、３９ｄによって遮光部材本体３２と表示パネル部１０ａとの隙間が密閉される。その結果、ＬＥＤ５０ｃの光が前記表示部１２以外の部分、特に第１操作ノブ２０および第２操作ノブ１２０側に漏えいするのが抑制されて、表示パネル部１０が適切に照明される。 In the display device 1 assembled as described above, the LED 50c is accommodated in a region surrounded by the walls 32a, 32b, 32c, and 32d of the light shielding member main body 32, and is formed by the rib-shaped minute protrusions 39c and 39d. A gap between the light shielding member main body 32 and the display panel unit 10a is sealed. As a result, the light from the LED 50c is prevented from leaking to portions other than the display unit 12, particularly the first operation knob 20 and the second operation knob 120, and the display panel unit 10 is appropriately illuminated.
　ここで、リブ状微小突起３９ｃ、３９ｄの具体的形状は前記に限らない。例えば、前方すなわち突出方向についてその幅が一定であってもよい。 Here, the specific shape of the rib- like microprojections 39c and 39d is not limited to the above. For example, the width may be constant in the forward direction, that is, in the protruding direction.
　また、リブ状微小突起３９ｃ、３９ｄは、遮光部材本体３２の前端面全体に設けられていてもよい。 Further, the rib- like minute projections 39 c and 39 d may be provided on the entire front end surface of the light shielding member main body 32.
　また、遮光部材本体３２およびリブ状微小突起３９ｃ、３９ｄの材料は前記に限らない。 Further, the materials of the light shielding member main body 32 and the rib- like minute protrusions 39c and 39d are not limited to the above.
　また、回路基板４０をパネル２に保持するための具体的構造は前記に限らない。例えば、回路基板４０に係止突起が設けられている一方パネル２に係止用孔が形成されており、この係止突起が係止用孔に係止されるような構造であってもよい。 Further, the specific structure for holding the circuit board 40 on the panel 2 is not limited to the above. For example, the circuit board 40 may be provided with a locking projection, and the panel 2 may have a locking hole, and the locking projection may be locked in the locking hole. .
　以上のように、本発明は、照明機能を有する表示装置であって、照明用光源が実装された回路基板と、透光性を有して前記照明用光源により後方から照明されることが可能な表示部を含む表示パネル部と、この表示パネル部から後方へ離間した位置に前記回路基板を保持する基板保持部とを有するパネルと、前記回路基板の前側面と前記表示パネル部の後側面との間に介在する遮光部材とを備え、前記遮光部材は、前記表示パネル部側から前記回路基板側に向かって延びて前記照明用光源から前記表示部に至る光路を囲む筒状を有するとともに軸方向両側に前端面および後端面を有する遮光部材本体と、この遮光部材本体の前端面の少なくとも一部の領域に当該前端面に沿って延びるように形成され、当該前端面の幅よりも小さい幅を有するとともに当該前端面から前記表示パネル部側に向かって突出する突出部とを有し、前記遮光部材本体は、その前端面から後端面までの距離に相当する軸方向寸法が、前記表示パネル部の後側面から前記基板保持部により保持された状態の前記回路基板の前側面までの離間距離よりも小さい形状を有し、前記突出部は、前記遮光部材本体の後端面が前記回路基板の前側面に接触した状態でこの遮光部材本体の前端面と前記表示パネル部の後側面との間に形成される隙間の寸法よりも大きな突出寸法を有し、これらの寸法同士の差に相当する分だけ圧縮変形した状態で前記表示パネル部の後側面に密着することが可能な形状を有することを特徴とする照明機能を有する表示装置を提供する。 As described above, the present invention is a display device having an illumination function, and is capable of being illuminated from behind by a circuit board on which an illumination light source is mounted and the translucent light source. A panel having a display panel unit including a display unit, a substrate holding unit for holding the circuit board at a position spaced rearward from the display panel unit, a front side surface of the circuit board, and a rear side surface of the display panel unit A light shielding member interposed between the light source and the light shielding member. The light shielding member has a cylindrical shape that extends from the display panel portion side toward the circuit board side and surrounds an optical path from the illumination light source to the display portion. A light shielding member main body having a front end surface and a rear end surface on both sides in the axial direction, and is formed to extend along the front end surface in at least a partial region of the front end surface of the light shielding member main body, and is smaller than the width of the front end surface Have width And a projecting portion projecting from the front end surface toward the display panel portion, and the shading member body has an axial dimension corresponding to a distance from the front end surface to the rear end surface of the display panel portion. The protrusion has a shape that is smaller than a separation distance from the rear side surface to the front side surface of the circuit board in a state of being held by the board holding unit, and the projecting portion has a rear end surface of the light shielding member body that is a front side surface of the circuit board Has a projecting dimension larger than the dimension of the gap formed between the front end surface of the light shielding member main body and the rear side surface of the display panel unit in a state of being in contact with the light shielding member, and is equivalent to the difference between these dimensions. Provided is a display device having an illumination function, characterized in that the display device has a shape that can be brought into close contact with the rear side surface of the display panel portion in a compressed and deformed state.
　この表示装置によれば、パネルと遮光部材とが別体でありパネルの塗装が容易であるとともに、パネルと遮光部材とを別体としたにも関わらず、前記回路基板の取り付け誤差等に伴ってパネルと回路基板との間の距離にばらつきがあったとしてもパネルと遮光部材との間に隙間が生じるのが回避される。すなわち、この表示装置では、前記パネルと回路基板との間の距離にばらつきがあっても、前記突出部が圧縮変形することでこのばらつきを吸収してこの突出部が前記表示パネル部の後側面と確実に密着する結果、前記表示パネル部と前記遮光部材本体との間の隙間が密閉される。このことは、この表示パネル部と遮光部材本体との間の隙間からの光の漏洩を抑制し、表示パネル部の適切な照明を実現する。 According to this display device, the panel and the light-shielding member are separate and the panel can be easily painted, and the panel and the light-shielding member are separated from each other. Even if there is a variation in the distance between the panel and the circuit board, it is possible to avoid a gap between the panel and the light shielding member. That is, in this display device, even if there is a variation in the distance between the panel and the circuit board, the projection is compressed and deformed to absorb the variation, and the projection is rear side of the display panel unit. As a result, the gap between the display panel unit and the light shielding member body is sealed. This suppresses light leakage from the gap between the display panel unit and the light shielding member main body, and realizes appropriate illumination of the display panel unit.
　また、前記パネルは、前記表示パネル部の表示部と隣接する位置にて当該表示パネル部に取付けられる操作部材を有し、前記遮光部材本体は、前記表示パネル部側から前記回路基板側に向かって延びて前記照明用光源から前記表示部への光路を囲むように並ぶ複数の側壁を有し、前記突出部は、前記側壁のうち少なくとも前記操作部材と前記表示部との境界部分に配置される側壁の前端面に沿って延びる形状を有するのが好ましい。この構成では、操作部材と表示部との境界部分において突出部により表示パネル部と遮光部材本体との間の隙間が密閉されるため、照明用光源の光がこの隙間から操作部材側に漏洩するのが有効に抑制される。 Further, the panel includes an operation member attached to the display panel unit at a position adjacent to the display unit of the display panel unit, and the light shielding member body is directed from the display panel unit side to the circuit board side. A plurality of side walls arranged so as to surround an optical path from the illumination light source to the display unit, and the projecting portion is disposed at least at a boundary portion between the operation member and the display unit among the side walls. It preferably has a shape extending along the front end surface of the side wall. In this configuration, since the gap between the display panel unit and the light shielding member body is sealed by the protrusion at the boundary between the operation member and the display unit, the light from the illumination light source leaks from the gap to the operation member side. Is effectively suppressed.
　さらに、前記突出部は、前記側壁のうち前記操作部材に最も近い位置に配置される側壁の前端面のみに形成されていてもよい。この構成では、圧縮変形させなければならない突出部の形成領域が最小限に抑えられるため、突出部を圧縮変形させる際にこの突出部に働く圧縮応力が集中する結果突出部の変形が容易になる。 Furthermore, the protrusion may be formed only on the front end surface of the side wall disposed at a position closest to the operation member among the side walls. In this configuration, since the formation area of the protruding portion that must be compressed and deformed is minimized, the compressive stress acting on the protruding portion concentrates when the protruding portion is compressed and deformed, so that the protruding portion is easily deformed. .
　また、前記突出部は、前記遮光部材本体側から前記表示パネル部側に向かうに従って幅が小さくなる形状を有するのが好ましい。この構成では、突出部を表示パネル部に押し付けた際にこの突出部の圧縮変形がより容易になる。 Further, it is preferable that the protruding portion has a shape whose width becomes smaller from the light shielding member main body side toward the display panel portion side. In this configuration, when the projecting portion is pressed against the display panel unit, the projecting portion is more easily compressed and deformed.
　また、本発明は、照明機能を有する表示装置を製造するための方法であって、透光性を有して前記照明用光源により後方から照明されることが可能な表示部を含む表示パネル部と、この表示パネル部から後方へ離間した位置に前記回路基板を保持する基板保持部とを有するパネルを製造する工程と、前記パネルとは別の遮光性を有する部材により、前記表示パネル部側から前記回路基板側に向かって延びて前記照明用光源から前記表示部に至る光路を囲む筒状を有するとともに軸方向両側に前端面および後端面を有する遮光部材本体と、この遮光部材本体の前端面の少なくとも一部の領域に当該前端面に沿って延びるように形成され、当該前端面の幅よりも小さい幅を有するとともに当該前端面から前記表示パネル部側に向かって突出する突出部とを有する遮光部材を製造する工程と、前記照明用光源を前記回路基板に実装する工程と、前記遮光部材を前記回路基板の前側面と前記表示パネル部の後側面との間に介在させた状態で前記基板保持部に前記回路基板を保持させる工程とを含み、前記遮光部材を製造する工程では、前記遮光部材の前記前端面から後端面までの距離に相当する軸方向寸法を前記表示パネル部の後側面から前記基板保持部により保持された状態の前記回路基板の前側面までの離間距離よりも小さくするとともに、前記突出部の突出寸法を前記遮光部材本体の後端面が前記回路基板の前側面に接触した状態でこの遮光部材本体の前端面と前記表示パネル部の後側面との間に形成される隙間の寸法よりも大きくする工程を含み、前記基板保持部に前記回路基板を保持させる工程では、前記回路基板により前記遮光部材本体の後端面を前記表示パネル部側に押圧させることで、この遮光部材本体の前端面と前記表示パネル部の後側面との間で前記突出部を圧縮変形させてこの突出部を前記表示パネル部の後側面に密着させることを特徴とする照明機能を有する表示装置の製造方法を提供する。 Further, the present invention is a method for manufacturing a display device having an illumination function, the display panel unit including a display unit having translucency and capable of being illuminated from behind by the illumination light source.

A step of manufacturing a light shielding member having a protruding portion, a step of mounting the illumination light source on the circuit board, and the light shielding member interposed between a front side surface of the circuit board and a rear side surface of the display panel unit. And holding the circuit board on the substrate holding part in a state where the light shielding member is manufactured, and in the step of manufacturing the light shielding member, an axial dimension corresponding to a distance from the front end surface to the rear end surface of the light shielding member is The distance from the rear side surface of the display panel portion to the front side surface of the circuit board held by the substrate holding portion is made smaller, and the protruding dimension of the protruding portion is the rear end surface of the light shielding member body. Including a step of making the size larger than a dimension of a gap formed between a front end surface of the light shielding member main body and a rear side surface of the display panel unit in a state of being in contact with a front side surface of the substrate, In the holding step, the projecting portion is formed between the front end surface of the light shielding member main body and the rear side surface of the display panel portion by pressing the rear end surface of the light shielding member main body toward the display panel portion by the circuit board. A method of manufacturing a display device having an illumination function is provided, in which the protrusion is brought into close contact with the rear side surface of the display panel portion.
　この方法によれば、パネルと遮光部材とが別体に形成されておりパネルの塗装が容易になる。しかも、前記基板保持部に前記回路基板を保持させる工程において、回路基板が遮光部材を押圧することで表示パネル部と回路基板との距離に応じて前記突出部が圧縮変形して表示パネル部に密着しており、簡単な手順でこの突出部すなわち遮光部材と表示パネル部との隙間が密閉される。この隙間の密閉は、この隙間から照明用光源の光が前記表示部以外の部分に漏洩するのを抑制する。

The protrusions, that is, the gaps between the light shielding member and the display panel unit are sealed with a simple procedure. The sealing of the gap prevents light from the illumination light source from leaking from the gap to portions other than the display section.
