That is, at this time, the apparatus main body 2 is lifted upward. And since the said 2nd hook part 24 leaves | separates from the said 2nd receiving part 34, the fulcrum of the said apparatus main body 2 turns into a front-end | tip part of the said downward nail | claw part 23. FIG. When the downward claw portion 23 gets over the upper end of the upward claw portion 30, the downward claw portion 23, and by extension, the apparatus main body 2 is lowered by gravity. Thereby, the downward claw portion 23 of the first hook portion 22 is engaged with the upward claw portion 30 of the first receiving portion 29 as shown in FIG.

なお、前記装置本体２を充電台３に取り付ける過程において、前記装置本体２が上方に持ち上げられると、前記第二掛部２４は前記第二受部３４から離れる。そして、前記第一掛部２２の下向き爪部２３が前記第一受部２９の上向き爪部３０の上端近傍に達すると、前記第二掛部２４の下端が前記第二受部３４の上向き爪部３５の上端よりも高い位置となる。即ち、前記第二掛部２４は、前記第二受部３４から外れた状態となる。しかしながら、前述した通り、前記下向き爪部２３の先端が支点となると、この支点の前方が支点の後方よりも常に重いので、前記第二掛部２４は、その後方にある前記起立部２７の前壁２７Ａに当接して支えられる。そして、前記下向き爪部２３が前記上向き爪部３０の上端を乗り越えて、前記装置本体２が重力によって下降すると、前記第二掛部２４は再び前記第二受部３４に上方から掛けられる。即ち、前記第一掛部２２は、前記第一受部２９に上方から掛けられると共に、前記第二掛部２４は、前記第二受部３４に上方から掛けられる。このようにして、前記装置本体２は前記充電台３に取り付けられる。 In addition, in the process of attaching the apparatus main body 2 to the charging stand 3, when the apparatus main body 2 is lifted upward, the second hanging portion 24 is separated from the second receiving portion 34. When the downward claw 23 of the first hook 22 reaches the vicinity of the upper end of the upward claw 30 of the first receiver 29, the lower end of the second hook 24 is the upward claw of the second receiver 34. The position is higher than the upper end of the portion 35. That is, the second hooking portion 24 is in a state of being detached from the second receiving portion 34. However, as described above, when the tip of the downward claw 23 serves as a fulcrum, the front of the fulcrum is always heavier than the rear of the fulcrum, so that the second hanging part 24 is in front of the upright part 27 behind it. It is supported in contact with the wall 27A. And when the said downward nail | claw part 23 gets over the upper end of the said upward claw part 30, and the said apparatus main body 2 descend | falls by gravity, the said 2nd hook part 24 will again be hung on the said 2nd receiving part 34 from upper direction. That is, the first hanging portion 22 is hung on the first receiving portion 29 from above, and the second hanging portion 24 is hung on the second receiving portion 34 from above. In this way, the apparatus main body 2 is attached to the charging stand 3.

前記装置本体２が前記充電台３に取り付けられると、前記各受電端子１５が、前記充電台３に形成された前記各溝部３１に挿入される。そして、前記各受電端子１５が前記各溝部３１に挿入されると、これらの溝部３１に設けられた給電端子３２の接点部３３が、それぞれ前記各受電端子１５に接触する。このように、前記各給電端子３２の接点部３３と前記各受電端子１５が接触することで、前記装置本体２内に収容された前記二次電池１２に電力が供給されるので、この二次電池１２が充電される。 When the apparatus main body 2 is attached to the charging stand 3, the power receiving terminals 15 are inserted into the groove portions 31 formed in the charging stand 3. When the power receiving terminals 15 are inserted into the groove portions 31, the contact portions 33 of the power supply terminals 32 provided in the groove portions 31 come into contact with the power receiving terminals 15, respectively. As described above, since the contact portion 33 of each of the power supply terminals 32 and each of the power receiving terminals 15 are in contact with each other, power is supplied to the secondary battery 12 accommodated in the device body 2. Battery 12 is charged.

このように、前記二次電池１２が充電されると、前記装置本体２を前記充電台３から取り外して使用することが可能となる。前述した通り、前記装置本体２は、その第一掛部２２が前記第一受部２９に上方から掛けられると共に、その第二掛部２４が前記第二受部３４に上方から掛けられることで、前記充電台３に取り付けられているので、上方に持ち上げることで、前記充電台３から取り外すことができる。即ち、前記装置本体２は、図１２に示すように、上方に持ち上げた後、図１３に示すように、前方に移動させることで、前記充電台３から容易に取り外される。なお、前記装置本体２は、前記下向き爪部２３が上向き爪部３０から外れる程度に持ち上げさえすれば、水平に前方に移動させても、斜め前方に移動させても、前記充電台３から取り外すことができる。即ち、前記装置本体２は、前記充電台３に対する取り外し姿勢の自由度が高い。そして、前記充電台３から取り外された前記装置本体２は、前記脚部５を任意の角度まで起こした後、前記外殻体６のゴム足１６と前記接地部２１のゴム足２５が設置面Ｓに接するように、この設置面Ｓに載置される。そして、起こされた前記脚部５の角度によって、前記装置本体２に設けられたＬＣＤユニット７、即ち画面の角度が調節される。この状態で、前記装置本体２は、放送電波を受信し、前記ＬＣＤユニット７の画面に映像を表示することができる。 Thus, when the secondary battery 12 is charged, the apparatus main body 2 can be detached from the charging stand 3 and used. As described above, the apparatus main body 2 has the first hanging portion 22 hung on the first receiving portion 29 from above and the second hanging portion 24 hung on the second receiving portion 34 from above. Since it is attached to the charging stand 3, it can be removed from the charging stand 3 by lifting upward. That is, the apparatus body 2 is easily removed from the charging stand 3 by being lifted upward as shown in FIG. 12 and then moved forward as shown in FIG. The apparatus main body 2 can be removed from the charging stand 3 even if it is moved horizontally forward or obliquely forward as long as the downward claw 23 is lifted to the extent that it can be removed from the upward claw 30. be able to. That is, the apparatus main body 2 has a high degree of freedom in the detaching posture with respect to the charging stand 3. The apparatus main body 2 removed from the charging base 3 raises the leg 5 to an arbitrary angle, and then the rubber feet 16 of the outer shell 6 and the rubber feet 25 of the grounding portion 21 are installed on the installation surface. It is placed on this installation surface S so as to be in contact with S. Then, the angle of the LCD unit 7 provided in the apparatus main body 2, that is, the angle of the screen is adjusted by the angle of the raised leg 5. In this state, the apparatus main body 2 can receive broadcast radio waves and display an image on the screen of the LCD unit 7.

なお、前記装置本体２は、前記充電台３に取り付けられた状態のまま使用することもできる。即ち、前記装置本体２は、前記各受電端子１５及び各給電端子３２が接続されたまま、放送電波を受信し、前記ＬＣＤユニット７の画面に映像を表示することができる。この際、前記各給電端子３２及び各受電端子１５を介して供給される電力は、前記二次電池１２には供給されない。 The apparatus main body 2 can be used as it is attached to the charging stand 3. That is, the apparatus main body 2 can receive broadcast radio waves and display images on the screen of the LCD unit 7 while the power receiving terminals 15 and the power supply terminals 32 are connected. At this time, the power supplied through the power supply terminals 32 and the power receiving terminals 15 is not supplied to the secondary battery 12.

そして、このように前記装置本体２が前記充電台３に取り付けられた状態で、前記脚部５に対して前記回動軸Ｘを中心に前記筐体部４を回動させることで、前記装置本体２は、そのＬＣＤユニット７の画面の仰角を調節することができる。この際、前述したように、前記各受電端子１５が、前記脚部５の回動軸Ｘ上に設けられると共に、前記各給電端子３２の接点部３３も、おおよそ前記回動軸Ｘ上に位置するので、前記脚部５に対して前記回動軸Ｘを中心に前記筐体部４を回動させたとしても、前記各受電端子１５と各給電端子３２の接点部３３との位置関係は殆ど変化しない。従って、前記ＬＣＤユニット７の画面の角度（仰角）を調節しても、前記各受電端子１５と前記各給電端子３２の接点部３３は接触し続ける。なお、図示しないが、前記装置本体２は、前記ＬＣＤユニット７の画面の仰角がマイナスとなるように伏せることもできる。従って、前記充電台３を使用者の視点よりも高い位置に置いても、前記装置本体２は、その画面に表示される映像を視聴しやすいようにすることができる。 Then, with the apparatus main body 2 attached to the charging base 3 in this manner, the casing 4 is rotated about the rotation axis X with respect to the leg 5, thereby the apparatus The main body 2 can adjust the elevation angle of the screen of the LCD unit 7. At this time, as described above, each of the power receiving terminals 15 is provided on the rotation axis X of the leg portion 5, and the contact portion 33 of each of the power supply terminals 32 is also approximately located on the rotation axis X. Therefore, even if the casing 4 is rotated about the rotation axis X with respect to the leg 5, the positional relationship between the power receiving terminals 15 and the contact portions 33 of the power feeding terminals 32 is as follows. Almost no change. Accordingly, even if the screen angle (elevation angle) of the LCD unit 7 is adjusted, the contact portions 33 of the power receiving terminals 15 and the power supply terminals 32 are kept in contact with each other. Although not shown, the apparatus main body 2 can be turned down so that the elevation angle of the screen of the LCD unit 7 is negative. Therefore, even if the charging stand 3 is placed at a position higher than the viewpoint of the user, the apparatus main body 2 can easily view the video displayed on the screen.

なお、前記第一掛部２２を、前記脚部５の脚１９に設けることも、理論的には可能である。しかしながら、この位置に前記第一掛部２２が設けられると、前記装置本体２の筐体部４を回動させる場合、作用点である前記第一掛部２２が、支点となる前記第二掛部２４に近く、力点となる筐体部４の上部から離れるので、前記第一掛部２２と第一受部２９との係合箇所に過大な力が加わり、これらの係合が外れる虞がある。しかしながら、本実施形態では、作用点である前記第一掛部２２を、可能な限り支点となる前記第二掛部２４から離し、力点となる筐体部４の上部に近付けたので、前記第一掛部２２と第一受部２９との係合箇所に過大な力が加わらず、これらの係合が外れにくくすることができる。 It is theoretically possible to provide the first hook 22 on the leg 19 of the leg 5. However, when the first hanging portion 22 is provided at this position, when the casing portion 4 of the apparatus main body 2 is rotated, the first hanging portion 22 that is an action point is the second hanging portion that becomes a fulcrum. Since it is close to the part 24 and away from the upper part of the casing part 4 which is a power point, an excessive force is applied to the engaging portion between the first hook part 22 and the first receiving part 29, and there is a possibility that these engagements are released. is there. However, in the present embodiment, the first hooking portion 22 that is the operating point is separated from the second hooking portion 24 that is the fulcrum as much as possible, and is close to the upper portion of the casing portion 4 that is the power point. Excessive force is not applied to the engagement portion between the first hook portion 22 and the first receiving portion 29, and it is possible to make it difficult for these engagements to be released.

以上のように、本発明は、装置本体２と充電台３を有して構成される充電式映像表示装置としてのテレビ１であって、前記装置本体２が、二次電池１２を内蔵すると共に後部に受電端子１５を有した筐体部４と、この筐体部４の背面側に、回動軸Ｘ回りに回動可能で且つ前記充電台３に取り付けられる脚部５を有し、前記回動軸Ｘ上に前記受電端子１５を設け、前記充電台３が給電端子３２を有すると共に、前記脚部５の基端側に第一掛部２２を設け、前記脚部５の先端側に第二掛部２４を設け、前記充電台３の起立部２７の正面である前壁２７Ａに、前記第一掛部２２を上方から受ける第一受部２９及び前記第二掛部２４を上方から受ける第二受部３４を設けたことで、前記装置本体２を前記充電台３に取り付けるために、前記脚部５を後方に突出させる必要がなくなるので、前記装置本体２のデザイン上の制約を小さくすることができるものである。 As described above, the present invention is a television 1 as a rechargeable video display device configured to include the device main body 2 and the charging stand 3, and the device main body 2 includes the secondary battery 12.
