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
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 thebottom case 2 shown in FIG.
As shown in FIG. 4, thelattice 10 of the portion of the air inlet 8 that is covered by the top case 1 is widened by a predetermined distance.

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
As shown in FIG. 4, the
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.
