  According to the configuration of the charger 1 described above, the main body case 2 has a wall facing the longitudinal direction of the main body case 2 with respect to the connector mounting portion 11 provided at one longitudinal end portion of the device mounting wall 9. The other end in the longitudinal direction of the device mounting wall 9 is open. Therefore, the mobile phone 51 can be easily set in the charger 1 by the following procedure.

  First, the mobile phone 51 is brought into contact with the other end portion in the longitudinal direction of the device placement wall 9. In this case, the mobile phone 51 is brought into contact with the end portion of the device mounting wall 9 obliquely from the upper side or the side direction without the need to place the mobile phone 51 vertically on the device mounting wall 9 from above. In this case, a part of the main body case 2 does not get in the way. In addition, the height of the other end side portion 6b of the side wall 6 is a height close to the surface of the device mounting wall 9, and the inclined portion 6c of the side wall 6 has an oblique shape that becomes lower toward the other end side portion 6b side. Therefore, the other end side portion 6b and the oblique portion 6c are unlikely to obstruct the operation for the contact, and do not interfere with the holding portion 6d of the side wall 6 at this stage.

  Subsequently, while maintaining the contact state of the mobile phone 51 with respect to the surface of the device placement wall 9, the mobile phone 51 is turned down so as to be parallel to the surface of the device placement wall 9, It pushes toward the connector attachment part 11 so that it may slide along the surface of the apparatus mounting wall 9, and is mounted in the apparatus mounting wall 9. FIG. As the push-in progresses, the frame 52 of the mobile phone 51 enters and approaches the holding portion 6d of the side wall 6, and the mobile phone 51 is pushed in while maintaining this state. By such pushing, the connector connection port 55 of the mobile phone 51 is fitted into the connector 21.

  In this case, the movement of the mobile phone 51 in the width direction is suppressed by contact between both side surfaces in the width direction and the upper part of the side plate 10 of the second case member 8, and the movement of the mobile phone 51 in the vertical direction (thickness direction) is the main body. It is suppressed by the device placement wall 9 of the case 2 and the holding portion 6d of the side wall 6. As a result, since the cellular phone 51 is pushed in with the connector connection port 55 positioned with respect to the connector 21, the connection of the connector connection port 55 to the connector 21 is smooth. Further, even if the user's finger touches the side wall 6 of the main body case 2 during the above setting operation, the side wall 6 has the oblique portion 6c, so that the corner of the finger hits the pain. It can be handled safely without giving.

  As described above, the mobile phone 51 is brought into contact with the connector 21 by a series of simple procedures in which the mobile phone 51 is brought into contact with the device placement wall 9 and then the mobile phone 51 is pushed using the device placement wall 9 as a guide. The mobile phone 51 can be set in the charger 1 in a mechanically and electrically connected state. The state where the setting is completed is shown in FIGS. The upper surface of the set charger 1, the upper surface of the cover part of the connector mounting portion 11, and the upper end of the one end side part 6 a of the side wall 6 are arranged to be substantially flush with each other at substantially the same height. .

  The mobile phone 51 can be carried along with the charger 1 in the above set completion state. In this case, as shown in FIG. 5, since substantially the entire front surface of the front panel 53 of the mobile phone 51 is exposed, the mobile phone 51 can be used in the set state.

  Moreover, in the set completion state, the end portion of the mobile phone 51 provided with the earpiece 62 is exposed without being covered with the side wall 6 including both side surfaces thereof. Thereby, not only the operation member 56 positioned on the end surface in the longitudinal direction of the mobile phone 51 is exposed, but also the operation members 57 to 59 on the side surface of the mobile phone 51 are exposed as shown in FIG. Is in a state. This latter exposure is realized by the side wall 6 of the main body case 2 having an oblique portion 6c and a lower other end portion 6b. Therefore, the mobile phone 51 can be used by operating the operation members 56 to 59 while the set is completed.

  In order to charge the secondary battery 25 of the charger 1 with the mobile phone 51 set or not set in the charger 1, the charger 1 is turned over as shown in FIG. What is necessary is just to enable the battery 31 to receive sunlight. In order to supply the power of the secondary battery that stores the power generated by the solar cell 31 in such a light receiving state to the mobile phone 51, the changeover switch 38 may be turned on in the set completion state. The electric power of the secondary battery 25 is supplied to the mobile phone 51 via.

  When the mobile phone 51 is carried together with the charger 1, if the mobile phone 51 that is cantilevered by the connector 21 may move excessively in the thickness direction, the connector 21 is mechanically moved accordingly. Overload acts. However, when the mobile phone 51 is set in the charger 1, as shown in FIG. 6, the side edge of the mobile phone 51, that is, the upper edge of the side of the frame 52 is opposed to this at a close distance. It is covered with a holding portion 6 d of the side wall 6, and the back surface of the mobile phone 51 is supported by the device placement wall 9. That is, the side edge of the mobile phone 51 is disposed so as to be sandwiched between the device placement wall 9 and the holding portion 6 d of the side wall 6.

  For this reason, the mobile phone 51 is prevented from being detached through the opened side wall 6 of the main body case 2 while being carried by the frame 52 forming the side edge of the mobile phone 51 being received by the holding portion 6d. Is done.

  At the same time, since the holding portion 6d prevents the mobile phone 51 connected to the connector 21 from moving excessively in the thickness direction, it is possible to suppress the connector 21 from being overloaded. Accordingly, it is possible to eliminate the fear that the connector 21 may be deformed obliquely, or that the connector 21 may not be supported properly due to cracks in the standing part of the connector mounting portion 11 through which the connector 21 passes.

  Further, as described above, when the mobile phone 51 is set in the charger 1, the end portion of the mobile phone 51 provided with the earpiece 62 is covered with the side wall 6 including both side surfaces thereof. It is in an exposed state. At the same time, the main body case 2 has no wall facing the connector mounting portion 11 provided at one end portion in the longitudinal direction of the device placement wall 9, and the other end in the longitudinal direction of the device placement wall 9 is open.

  Therefore, when removing the mobile phone 51 from the charger 1, the end of the mobile phone 51 provided with the earpiece 62 can be gripped, whereby the mobile phone 51 can be easily grasped and the connector mounting portion 11. Can be pulled away from In this case, the main body case 2 is not disturbed. Accordingly, the cellular phone 51 can be easily detached from the connector 21 along with the pulling, and the cellular phone 51 is continuously moved along the device placement wall 9 without changing the direction of the separation. The mobile phone 51 can be disconnected from the charger 1 by being pulled.

  As described above, according to the charger 1 of the embodiment, since the mobile phone 51 placed on the device mounting wall 9 can be easily attached to and detached from the connector 21, it is easy to use and the mobile phone 51 is attached to the main body case 2. In the state where the mobile phone 51 is set, it is possible to reduce the load on the connector 21 as the mobile phone 51 can be prevented from moving excessively in the thickness direction.

  The present invention is not limited to the one embodiment. For example, in one embodiment, the frame 52 that forms a step in the peripheral portion of the mobile phone (portable information device terminal) 51 can be received by the holding portion 6d, but the information terminal device having no frame is attached and detached. In this case, the upper surface of the peripheral side portion of the information terminal device can be used as a side edge so that the side edge can be received by the holding portion 6d of the side plate 6. Furthermore, when the side edge of the information device terminal has a step at a position lower than the upper surface of the information device terminal, the holding portion disposed so as to be able to receive the step forms the upper edge of the side wall. Is not restricted, and may be provided at an intermediate position in the height direction of the side wall.

  Moreover, since the side wall 6 demonstrated by the said one embodiment is continuing over the longitudinal direction full length of the main body case 2, when the side wall 6 is pushed with a user's finger | toe, it is hard to deform | transform so that it may mutually approach. And since the other end side part 6b is low, a deformation | transformation is suppressed further. Thereby, since the mutual space | interval of the side wall 6 is hard to be narrowed when the other end side part 6b of the opposite side wall 6 is pushed with a user's finger | toe, on the longitudinal direction other end part of the apparatus mounting wall 9 There is an advantage that there is no fear of hindering when the mobile phone 51 is placed.

  However, in the present invention, instead of omitting the other end side portion 6b where the side wall 6 is low, the tip of the inclined portion 6c is provided so as to be in contact with the longitudinal middle portion of the device mounting wall 9, or It is also possible to carry out by providing the shaped portion 6c extending to the other end in the longitudinal direction of the device mounting wall 9. In this case, the oblique edge of the oblique portion 6c may be a hypotenuse or an arcuate side.
