The cylindrical wall portion 13 extends from the position of the USB port 20 in the insertion / extraction direction of the wireless communication unit 40. As a result, the main body 44 of the wireless communication unit 40 is surrounded by the cylindrical wall 13.
　筒状の壁部１３は、無線通信ユニット４０が挿入される挿入口１４を形成している。この挿入口１４の奥側の端部にＵＳＢポート２０が配置されている。筒状の壁部１３の内面は、挿入口１４に挿入された無線通信ユニット４０と当接するか近接している。 The cylindrical wall 13 forms an insertion port 14 into which the wireless communication unit 40 is inserted. A USB port 20 is disposed at the back end of the insertion port 14. The inner surface of the cylindrical wall portion 13 is in contact with or close to the wireless communication unit 40 inserted into the insertion port 14.
　ＵＳＢアダプタ１０のＵＳＢポート２０に接続された無線通信ユニット４０は、筒状の壁部１３で覆われているため、筒状の壁部１３に支持される。したがって、無線通信ユニット４０のサイズや重量が大きかったとしても、無線通信ユニット４０の接続不良やＵＳＢコネクタ２０，４２の破損が抑制される。 The wireless communication unit 40 connected to the USB port 20 of the USB adapter 10 is supported by the cylindrical wall portion 13 because it is covered by the cylindrical wall portion 13. Therefore, even if the size and weight of the wireless communication unit 40 are large, poor connection of the wireless communication unit 40 and breakage of the USB connectors 20 and 42 are suppressed.
　また、筒状の壁部１３によって無線通信ユニット４０の四方が取り囲まれるため、無線通信ユニット４０が重力方向に関して様々な方向に向けられたとしても、筒状の壁部１３は無線通信ユニット４０を支持することができる。 Moreover, since the four sides of the wireless communication unit 40 are surrounded by the cylindrical wall portion 13, even if the wireless communication unit 40 is directed in various directions with respect to the direction of gravity, the cylindrical wall portion 13 does not support the wireless communication unit 40. Can be supported.
　近年、任意の方向に向けて設置可能なチルトフリー構造を有するプロジェクタが開発されている。そのようなプロジェクタにＵＳＢアダプタ１０が接続または搭載される場合、ＵＳＢアダプタ１０も任意の方向に向けて設置されることになる。このような場合であっても、筒状の壁部１３によって無線通信ユニット４０の四方が取り囲まれるので、無線通信ユニット４０の接続不良やＵＳＢコネクタ２０，４２の破損を抑制することができる。 Recently, a projector having a tilt-free structure that can be installed in any direction has been developed. When the USB adapter 10 is connected to or mounted on such a projector, the USB adapter 10 is also installed in an arbitrary direction. Even in such a case, since the four sides of the wireless communication unit 40 are surrounded by the cylindrical wall portion 13, it is possible to suppress poor connection of the wireless communication unit 40 and breakage of the USB connectors 20 and 42.
　筒状の壁部１３は、ＵＳＢアダプタ１０のＵＳＢポート２０の位置から、少なくともＵＳＢポート２０に接続された状態の無線通信ユニット４０の重心位置まで延びていることが好ましい。また、筒状の壁部１３は、ＵＳＢアダプタ１０のＵＳＢポート２０の位置から、少なくともＵＳＢポート２０に接続された状態の無線通信ユニット４０の、挿抜方向における全長Ｌｔの少なくとも２／３の長さに相当する部分Ｌ１を覆っていることがより好ましい（図１１参照）。これにより、筒状の壁部１３は、無線通信ユニット４０を効果的に支持し、ＵＳＢポート２０およびＵＳＢ端子４２に生じる負荷を効果的に軽減することができる。 The cylindrical wall portion 13 preferably extends from the position of the USB port 20 of the USB adapter 10 to at least the center of gravity of the wireless communication unit 40 connected to the USB port 20. Further, the cylindrical wall portion 13 has a length of at least 2/3 of the total length Lt in the insertion / extraction direction of the wireless communication unit 40 connected to at least the USB port 20 from the position of the USB port 20 of the USB adapter 10. It is more preferable to cover the portion L1 corresponding to (see FIG. 11). Thereby, the cylindrical wall part 13 can support the wireless communication unit 40 effectively, and can reduce the load which arises in the USB port 20 and the USB terminal 42 effectively.
　図１，図３，図４および図１１に示されているように、無線通信ユニット４０がＵＳＢアダプタ１０に取り付けられたとき、無線通信ユニット４０の、ＵＳＢ端子４２とは反対側の端部が筐体１２から露出することが好ましい。無線通信ユニット４０の、筐体１２から露出した部分は、ユーザの指でしっかりとつまむことができる程度の長さを有していれば良い。これにより、ユーザは、ＵＳＢアダプタ１０から無線通信ユニット４０を容易に取り外すことができる。 As shown in FIGS. 1, 3, 4, and 11, when the wireless communication unit 40 is attached to the USB adapter 10, the end of the wireless communication unit 40 opposite to the USB terminal 42 is It is preferable to expose from the housing 12. The part exposed from the housing | casing 12 of the wireless communication unit 40 should just have the length of the grade which can be pinched firmly with a user's finger | toe. Thereby, the user can easily remove the wireless communication unit 40 from the USB adapter 10.
　筒状の壁部１３の内面に、無線通信ユニット４０のＵＳＢ端子４２をＵＳＢポート２０の位置に案内するガイド機構１６，１８が形成されていることが好ましい（図２および図６～１０参照）。無線通信ユニット４０の本体部４４の外郭の形状を利用し、無線通信ユニット４０のＵＳＢ端子４２を筐体１２内のＵＳＢポート２０へ案内することで、ユーザは、ＵＳＢポート２０が見えない状況下においても容易に無線通信ユニット４０をＵＳＢアダプタ１０に接続することができる。 Guide mechanisms 16 and 18 for guiding the USB terminal 42 of the wireless communication unit 40 to the position of the USB port 20 are preferably formed on the inner surface of the cylindrical wall portion 13 (see FIGS. 2 and 6 to 10). . By using the outer shape of the main body 44 of the wireless communication unit 40 and guiding the USB terminal 42 of the wireless communication unit 40 to the USB port 20 in the housing 12, the user cannot see the USB port 20. In this case, the wireless communication unit 40 can be easily connected to the USB adapter 10.
　次に、ガイド機構の具体的な一例について説明する。ガイド機構１６，１８は、トップカバー１２ａとボトムカバー１２ｂの両方に形成されていることが好ましい。本例では、トップカバー１２ａに、無線通信ユニット４０の挿抜方向に沿って延びる第１の凸部１６ａと第２の凸部１６ｂとが形成されている。第１の凸部１６ａと第２の凸部１６ｂとの間の距離は、ＵＳＢポート２０に近づくとともに広くなっている。 Next, a specific example of the guide mechanism will be described. The guide mechanisms 16 and 18 are preferably formed on both the top cover 12a and the bottom cover 12b. In this example, a first convex portion 16a and a second convex portion 16b extending along the insertion / extraction direction of the wireless communication unit 40 are formed on the top cover 12a. The distance between the first convex portion 16a and the second convex portion 16b becomes wider as the USB port 20 is approached.
　同様に、ボトムカバー１２ｂに、無線通信ユニット４０の挿抜方向に沿って延びる第３の凸部１８ａと第４の凸部１８ｂとが形成されている。第３の凸部１８ａと第４の凸部１８ｂとの間の距離は、ＵＳＢポート２０に近づくとともに広くなっている。 Similarly, the bottom cover 12b is formed with a third convex portion 18a and a fourth convex portion 18b extending along the insertion / extraction direction of the wireless communication unit 40. The distance between the third convex portion 18a and the fourth convex portion 18b becomes wider as the USB port 20 is approached.
　無線通信ユニット４０の本体部４４の外郭は、ＵＳＢアダプタ１０の第１の凸部１６ａに対応する第５の凸部４６ａ、ＵＳＢアダプタ１０の第２の凸部１６ｂに対応する第６の凸部４６ｂ、ＵＳＢアダプタ１０の第３の凸部１８ａに対応する第７の凸部４８ａおよびＵＳＢアダプタ１０の第４の凸部１８ｂに対応する第８の凸部４８ｂを有する。無線通信ユニット４０が挿入口１４に挿入される間、ＵＳＢアダプタ１０の第１の凸部１６ａと第２の凸部１６ｂが、無線通信ユニット４０の第５の凸部４６ａと第６の凸部４６ｂとの間に位置する。同様に、ＵＳＢアダプタ１０の第３の凸部１８ａと第４の凸部１８ｂが、無線通信ユニット４０の第７の凸部４８ａと第８の凸部４８ｂとの間に位置する。第１の凸部１６ａと第２の凸部１６ｂとの間の距離と、第３の凸部１８ａと第４の凸部１８ｂとの間の距離とが、ＵＳＢポート２０に近づくとともに広くなっているので、無線通信ユニット４０がＵＳＢポート２０に近づくとともに、挿抜方向に交差する方向の無線通信ユニット４０の位置がＵＳＢポート２０の位置に合わされる。 The outline of the main body 44 of the wireless communication unit 40 includes a fifth convex portion 46a corresponding to the first convex portion 16a of the USB adapter 10 and a sixth convex portion corresponding to the second convex portion 16b of the USB adapter 10. 46b, a seventh convex portion 48a corresponding to the third convex portion 18a of the USB adapter 10, and an eighth convex portion 48b corresponding to the fourth convex portion 18b of the USB adapter 10. While the wireless communication unit 40 is inserted into the insertion port 14, the first convex portion 16a and the second convex portion 16b of the USB adapter 10 are replaced with the fifth convex portion 46a and the sixth convex portion of the wireless communication unit 40. 46b. Similarly, the third convex portion 18a and the fourth convex portion 18b of the USB adapter 10 are located between the seventh convex portion 48a and the eighth convex portion 48b of the wireless communication unit 40. The distance between the first convex portion 16a and the second convex portion 16b and the distance between the third convex portion 18a and the fourth convex portion 18b become wider as the USB port 20 is approached. Therefore, the wireless communication unit 40 approaches the USB port 20, and the position of the wireless communication unit 40 in the direction intersecting the insertion / extraction direction is matched with the position of the USB port 20.
　図１２および図１３は、上記のＵＳＢアダプタ１０が接続されたプロジェクタ６０を示している。プロジェクタ６０が机の上等に置かれる場合、ＵＳＢアダプタ１０は、プロジェクタ６０の横で机の上等に置かれて良い（図１２参照）。ＵＳＢアダプタ１０は、ケーブル６４を介してプロジェクタ６０と接続される。 12 and 13 show the projector 60 to which the USB adapter 10 is connected. When the projector 60 is placed on a desk or the like, the USB adapter 10 may be placed on the desk or the like beside the projector 60 (see FIG. 12). The USB adapter 10 is connected to the projector 60 via the cable 64.
　プロジェクタ６０は、各種のケーブルを収容するケーブル室６２を備えていて良い。この場合、ＵＳＢアダプタ１０は、ケーブル室６２内に置かれて良い（図１３参照）。なお、図１３では、ケーブル室６２内のＵＳＢアダプタ１０および無線通信ユニット４０を点線によって示している。ＵＳＢアダプタ１０および無線通信ユニット４０がケーブル室６２内に配置された場合、ユーザからＵＳＢアダプタ１０および無線通信ユニット４０は見えない。したがって、無線通信機能を有するプロジェクタ６０であるという印象をユーザに与えることができる。 The projector 60 may include a cable chamber 62 that accommodates various cables. In this case, the USB adapter 10 may be placed in the cable chamber 62 (see FIG. 13). In FIG. 13, the USB adapter 10 and the wireless communication unit 40 in the cable chamber 62 are indicated by dotted lines. When the USB adapter 10 and the wireless communication unit 40 are arranged in the cable chamber 62, the USB adapter 10 and the wireless communication unit 40 are not visible to the user. Therefore, an impression that the projector 60 has a wireless communication function can be given to the user.
　上記の例では、使用時に、無線通信ユニット４０はＵＳＢアダプタ１０に直接接続されている。しかしながら、無線通信ユニット４０は、図１４および図１５に示すように、ＵＳＢ延長ケーブル６６を介してＵＳＢアダプタ１０に接続されても良い。これにより、無線通信ユニット４０の設置位置を柔軟に変えることが可能になる。 In the above example, the wireless communication unit 40 is directly connected to the USB adapter 10 during use. However, the wireless communication unit 40 may be connected to the USB adapter 10 via the USB extension cable 66 as shown in FIGS. As a result, the installation position of the wireless communication unit 40 can be flexibly changed.
　ＵＳＢアダプタ１０がプロジェクタ６０のケーブル室６２内に収容される場合、ＵＳＢアダプタ１０の設置位置は強く制限される。また、プロジェクタ６０に接続される各種のケーブルがＵＳＢアダプタ１０に近接するため、電波障害が発生する可能性も想定される。ここで、無線通信用のアンテナを有する無線通信ユニット４０をＵＳＢ延長ケーブル６６を介してＵＳＢアダプタ１０に接続することで、ＵＳＢアダプタ１０の位置を固定したまま無線通信ユニット４０の位置を柔軟に変更することができる。このように、無線通信アンテナを有する無線通信ユニット４０と、ＵＳＢアダプタ１０とを別々のモジュールとして構成することによって、電波障害を容易に回避することができるようになる。 When the USB adapter 10 is accommodated in the cable chamber 62 of the projector 60, the installation position of the USB adapter 10 is strongly limited. In addition, since various cables connected to the projector 60 are close to the USB adapter 10, there is a possibility that radio wave interference may occur. Here, by connecting the wireless communication unit 40 having the antenna for wireless communication to the USB adapter 10 via the USB extension cable 66, the position of the wireless communication unit 40 can be flexibly changed while the position of the USB adapter 10 is fixed. can do. In this way, by configuring the wireless communication unit 40 having the wireless communication antenna and the USB adapter 10 as separate modules, radio wave interference can be easily avoided.
