FIGS. 1G to 1J are views of only the bottom case 2 viewed from the front, left and right sides, and the back, and correspond to FIGS. 1B to 1E, respectively.
　図２は、図１（ｂ）のＢ－Ｂ方向における、映像投射方向を下にした断面図である。
　図３は、図１（ｄ）のＡ－Ａ方向における正面から見た断面図の一部である。
　図１，図２に示すように、プロジェクタ装置は、トップケース１とボトムケース２で構成され、内部にはレンズ４と、光源５と、冷却ファン６と、基板７と、吸気口８と、排気口９を備える。また、プロジェクタ装置は、図３に示すように、トップケース１の天板と一体形成される吸排気口カバー３を備える。 FIG. 2 is a cross-sectional view with the image projection direction down in the BB direction of FIG.
FIG. 3 is a part of a cross-sectional view seen from the front in the AA direction of FIG.
As shown in FIGS. 1 and 2, the projector device includes a top case 1 and a bottom case 2, and includes a lens 4, a light source 5, a cooling fan 6, a substrate 7, an air inlet 8, An exhaust port 9 is provided. Further, as shown in FIG. 3, the projector device includes an intake / exhaust port cover 3 formed integrally with the top plate of the top case 1.
　トップケース１とボトムケース２は、プロジェクタ装置において画像を投射するための各構成部品を外側から包み込み筺体を形成するケースであり、トップケース１が上面、ボトムケース２が下面となって筺体を形成する。なお、図１（ｂ）～（ｅ）に示すように、正面、背面、両側面の全てにおいて、ボトムケース２は、トップケース１により覆われるように構成されている。 The top case 1 and the bottom case 2 are cases in which each component for projecting an image in the projector device is wrapped from the outside to form a housing, and the top case 1 forms the housing with the top surface and the bottom case 2 the bottom surface. To do. As shown in FIGS. 1B to 1E, the bottom case 2 is configured to be covered with the top case 1 on all of the front, back, and both side surfaces.
　光源５は、プロジェクタ装置の正面に設けられたレンズ４を介して画像を投射するための光を発する。冷却ファン６は、光源５の発熱で熱せられた空気を吸引する。基板７は、映像投射に必要な部品を搭載する。吸気口８は、図１（ｄ），（ｉ）のように、ボトムケース２の映像投射方向に対して左側側面に備えられ、プロジェクタ装置の外から空気を吸い込む。排気口９は、図１（ｃ），（ｈ）のように、ボトムケース２の映像投射方向に対して右側側面に備えられ、冷却ファン６が吸引する熱せられた空気をプロジェクタ装置の外へ排出する。 The light source 5 emits light for projecting an image via a lens 4 provided in front of the projector device. The cooling fan 6 sucks air heated by the heat generated by the light source 5. The board 7 carries components necessary for video projection. As shown in FIGS. 1D and 1I, the air inlet 8 is provided on the left side surface with respect to the video projection direction of the bottom case 2, and sucks air from outside the projector device. As shown in FIGS. 1C and 1H, the exhaust port 9 is provided on the right side surface with respect to the image projection direction of the bottom case 2, and the heated air sucked by the cooling fan 6 is moved out of the projector device. Discharge.
　吸排気口カバー３は、トップケース１の天板と一体形成され、ボトムケース２の側面に配した吸気口８および排気口９と対面し、吸気口８および排気口９を覆うように構成されている。また、図３に示すように、吸排気口カバー３は、吸気口８および排気口９からそれぞれ一定の距離（例えば３０ｍｍ程度）をおいて空間が設けられている。この空間を設けることによって、吸気口８を通る空気が下側から、もしくは、排気口９を通る空気が下側へ流れるように構成されている。なお、図３では排気口９側のみ図示しているが、吸気口８側についても同様の構成となっている。また、吸気口８および排気口９から一定の距離とは、プロジェクタ装置に外部の空気を吸引、または、プロジェクタ装置から外部に空気を排出するのに十分な間隔であり、指が入る程度の間隔があればさらによい。 The intake / exhaust port cover 3 is formed integrally with the top plate of the top case 1, and faces the intake port 8 and the exhaust port 9 arranged on the side surface of the bottom case 2, and is configured to cover the intake port 8 and the exhaust port 9. ing. As shown in FIG. 3, the intake / exhaust port cover 3 is provided with a space at a certain distance (for example, about 30 mm) from the intake port 8 and the exhaust port 9. By providing this space, the air passing through the intake port 8 flows from the lower side, or the air passing through the exhaust port 9 flows downward. In FIG. 3, only the exhaust port 9 is shown, but the intake port 8 has the same configuration. The fixed distance from the intake port 8 and the exhaust port 9 is a sufficient interval for sucking outside air to the projector device or discharging air from the projector device to the outside, and an interval enough for a finger to enter. Even better if there is.
　なお、通常、プロジェクタ装置は人の目線より低い位置に設置して使用されるのが一般的であるため、人の目線において吸排気口が見えない程度に覆われていればよい。従って、例えば、図１（ｃ），（ｄ）のように、吸気口８と排気口９の一部が吸排気口カバー３に覆われていなくてもよい。 In general, the projector device is generally used by being installed at a position lower than the human eye. Therefore, the projector device only needs to be covered to such an extent that the intake and exhaust ports cannot be seen from the human eye. Accordingly, for example, as shown in FIGS. 1C and 1D, a part of the intake port 8 and the exhaust port 9 may not be covered with the intake / exhaust port cover 3.
　図４は、この発明の実施の形態１に係るプロジェクタ装置の吸気口の形状を示す図である。つまり、図１（ｄ）に示す側面図の、トップケース１を外したときの側面であり、図１（ｉ）に示したボトムケース２の、吸気口のみを示している図である。
　図４に示すように、トップケース１に覆われる部分の吸気口８の格子１０が、所定の間隔広げられている。 FIG. 4 is a diagram showing the shape of the air inlet of the projector device according to Embodiment 1 of the present invention. That is, it is a side view of the side view shown in FIG. 1D when the top case 1 is removed, and shows only the air inlet of the bottom case 2 shown in FIG.
As shown in FIG. 4, the lattice 10 of the portion of the air inlet 8 that is covered by the top case 1 is widened by a predetermined distance.
　従来、衝撃耐性確保のため、吸排気口には格子が必要とされているが、この発明の実施の形態１に係るプロジェクタ装置においては、吸気口８および排気口９を吸排気口カバー３が覆うように構成されているため、図４のように、吸排気口カバー３で覆われている部分、つまり、吸気口８の上部（図４のＤの部分）の格子１０の間隔を、吸排気口カバー３で覆われていない部分、つまり、吸気口８の下部（図４のＥの部分）より広くとり格子１０を必要最小限の細さとしている。なお、格子１０の間隔とは、縦方向、横方向の両方の間隔のことをいい、衝撃耐性が確保できる程度に広ければよく、格子１０の細さは、衝撃耐性が確保できる程度に細くすればよい。また、ここでは図４のように吸気口８を例にとって説明したが、排気口９についても同様の構成とする。 Conventionally, a grid is required at the intake and exhaust ports to ensure impact resistance. However, in the projector device according to Embodiment 1 of the present invention, the intake and exhaust port covers 3 are connected to the intake ports 8 and 9. As shown in FIG. 4, the portion covered with the intake / exhaust port cover 3, that is, the space between the lattices 10 at the upper portion of the intake port 8 (portion D in FIG. 4) is sucked. The grid 10 is made as thin as necessary to make it wider than the portion not covered with the exhaust port cover 3, that is, the lower portion of the intake port 8 (portion E in FIG. 4). Note that the interval between the lattices 10 refers to both the vertical and lateral intervals, as long as they are wide enough to ensure impact resistance, and the lattice 10 is thin enough to ensure impact resistance. That's fine. Further, here, the intake port 8 has been described as an example as shown in FIG. 4, but the exhaust port 9 has the same configuration.
　吸排気口が全て吸排気口カバー３に覆われるように構成することも可能であるが、この場合も、吸気口８と排気口９のボトムケース側、つまり、吸気口８および排気口９の下部、塵等の進入を防ぐため、図４のようにトップケース１側、つまり、吸気口８および排気口９の上部の格子よりも間隔を狭くしておく。 Although it is possible to configure the intake / exhaust ports so that they are all covered with the intake / exhaust port cover 3, in this case as well, the bottom case side of the intake port 8 and the exhaust port 9, that is, the intake port 8 and the exhaust port 9 In order to prevent entry of dust, etc. in the lower part, the interval is made narrower than the lattice on the top case 1 side, that is, the upper part of the intake port 8 and the exhaust port 9 as shown in FIG.
　以上のように、この実施の形態１によれば、吸排気口カバーがトップケースと一体形成されていることにより、使用時に動かす手間を必要としない。また、部品点数およびコストを削減することができる。また、吸排気口カバーが煩雑な吸排気口を隠し、すっきりとした外観を形成することができる。また、吸排気口カバーが吸排気口に覆われていることで、光源の光漏れを減少させることができる。また、吸排気口の格子の間隔を広くとり、格子を必要最小限の細さとしたため、同じ吸排気口の面積でも、より高い開口率で吸気口と排気口を形成することが可能となる。また、吸排気口カバーとボトムケースの間の空間に指を差し込むことができ、持ち運びが簡単に行なえる。 As described above, according to the first embodiment, since the intake / exhaust port cover is integrally formed with the top case, there is no need to move it during use. Moreover, the number of parts and cost can be reduced. Further, the intake / exhaust port cover can hide the complicated intake / exhaust port, and a clean appearance can be formed. Further, since the intake / exhaust port cover is covered by the intake / exhaust port, light leakage of the light source can be reduced. In addition, since the interval between the lattices of the intake and exhaust ports is widened and the lattice is made as thin as necessary, the intake and exhaust ports can be formed with a higher opening ratio even with the same area of the intake and exhaust ports. In addition, a finger can be inserted into the space between the intake / exhaust port cover and the bottom case, so that it can be easily carried.

　なお、実施の形態１で説明したものと同様の構成については、重複した説明を省略する。この実施の形態２と実施の形態１との相違点は、図７に示すように、実施の形態１における吸気口８と排気口９に形成する格子１０を、図７の縦状部材１１のように変形させた点である。なお、図７では排気口９側のみ図示しているが、排気口８側についても同様の構成とする。 FIG. 6 is a cross-sectional view with the image projection direction down in the BB direction of FIG.
FIG. 7 is a part of a cross-sectional view as seen from the front in the AA direction of FIG.
Note that the description of the same configuration as that described in Embodiment 1 is omitted. The difference between the second embodiment and the first embodiment is that, as shown in FIG. 7, the lattice 10 formed at the intake port 8 and the exhaust port 9 in the first embodiment is different from the vertical member 11 of FIG. This is the point of deformation. 7 shows only the exhaust port 9 side, the exhaust port 8 side has the same configuration.
　この実施の形態２における吸気口８および排気口９は、図５（ｆ）のように、縦状に伸びスリットの入った縦状部材１１で形成されており、縦状部材１１は、トップケース１方向に湾曲し、縦状部材１１の先端は、対向する吸排気口カバー３の下方端部よりも上部で当接するように構成されている。このように構成することで、図７に示すように、間に指が入る程度に窪ませた形状の吸気口８および排気口９が形成される。それにより、吸排気口カバー３が取っ手となり、プロジェクタ装置を運ぶ際には、この取っ手に指をひっかけて持ち運ぶことができる。（図８参照） As shown in FIG. 5 (f), the intake port 8 and the exhaust port 9 in the second embodiment are formed by a vertical member 11 extending vertically and having slits, and the vertical member 11 is a top case. Curved in one direction, the tip of the vertical member 11 is configured to abut on the upper side of the lower end of the opposed intake / exhaust port cover 3. By configuring in this way, as shown in FIG. 7, the intake port 8 and the exhaust port 9 are formed so as to be recessed to the extent that a finger can be inserted therebetween. Thereby, the intake / exhaust port cover 3 becomes a handle, and when carrying the projector device, it is possible to carry the projector device with a finger caught on the handle. (See Figure 8)
　以上のように、この実施の形態２によれば、実施の形態１の効果に加え、吸排気口カバーが取っ手となるように構成されているため、より持ち運びのしやすいプロジェクタ装置を提供することができる。 As described above, according to the second embodiment, in addition to the effects of the first embodiment, since the intake / exhaust port cover is configured as a handle, a projector device that is easier to carry is provided.
