In the invention disclosed in Patent Document 1, since it is necessary to electrically connect the PDA 10 that the cradle device is positioned and fixed to supply power for charging, the PDA 10 is positioned and fixed to the device main body 21 at a predetermined position. This is a desirable configuration for a predetermined electrical connection for charging.

However, the PDA receiving portion 21d is fitted into the PDA 10 only when the PDA 10 needs to be charged, and when the PDA 10 is not fitted, the PDA receiving portion 21d is exposed to the outside. Become.
In particular, the PDA receiving portion 21d is provided with an I / O connector 22 for supplying charging power. Accumulation of dust in the PDA receiving portion 21d may cause a short circuit or a poor electrical connection. It is a big problem.

Further, in the invention disclosed in Patent Document 1, the PDA receiving portion 21d is configured such that only the PDA 10 of a corresponding size is fitted and positioned and fixed, and other PDAs of different sizes are fitted and positioned and fixed. Can not be used. That is, there is also a problem that there is no versatility.
In particular, today, many portable electric and electronic devices have different sizes from the viewpoint of energy saving, despite the fact that a secondary battery is built in and power is charged from the outside. For this reason, the portable electric / electronic device of the device to be charged does not have versatility in the concave portion of the charging device. Therefore, the charging device is required only for the type of the device to be charged, and the problem is more serious.

In order to solve this problem, it is conceivable to increase the versatility of the second device by forming the concave portion of the first device sufficiently large.
However, for example, in the case where the first device is a charging device and the second device is a device to be charged as described above, the two devices are placed at predetermined positions in which the positions of the electrodes are associated with each other. If positioning is required and positioning is not performed accurately, there is a problem that the plus and minus poles do not correspond to each other and the device itself may be damaged.

  The present invention has been made in view of the above circumstances. A concave portion is formed in the first device, and the second device is fitted into the concave portion so that the second device is positioned and fixed at a predetermined position. Even when the device is not fitted in the recess, dust can be prevented from entering and collecting in the recess, and the recess is a case where the second device is different in size from each other. However, the present invention provides a positioning and fixing structure that can be positioned and fixed at a predetermined position when fitted into the recess.

According to the present invention, a lid that can be accommodated in the concave portion of the first device that can be fitted and positioned and fixed by fitting the second device is accommodated in the concave portion when folded, and a lid that can close the opening of the concave portion when expanded. This is a positioning and fixing structure.
The detailed configuration is a positioning and fixing structure in which a recess is formed in the first device, and when the second device is fitted in the recess, the positioning and fixing structure is positioned and fixed at a predetermined position.
Positioning that is foldable on the periphery of the opening of the recess, and that is supported by a lid that can close the opening of the recess when expanded and can be partially or wholly accommodated when folded. It is a fixed structure.

The first device is specifically a charging device, and the second device is specifically a charged device. More specifically, examples of the second device include a mobile phone, a transceiver, and a portable AV device.
Therefore, in these cases, the second device is positioned and fixed in the recess of the first device in order to exchange charging power between the first device and the second device. Then, the structure which can obtain the state of electrical connection is mentioned.

In addition, the lid body is specifically connected to a plurality of plate members that can be opened and closed in a folding screen by pivots, and when the adjacent plate members are opened to take an expanded posture. There is a configuration in which a flat state is obtained and a folded state can be obtained when the closed state is taken.
Therefore, if a part or all of the lid is folded and stored in the recess, the lid is reduced in size by the volume of the lid.

  According to the present invention, a lid that can be folded, can close the opening of the recessed portion for forming the partition in the first device when expanded, and a lid that can be partially or wholly stored in the recessed portion when folded. Since the second device is not fitted in the concave portion of the first device because it is pivotally supported at the periphery, dust or the like enters the concave portion by closing the opening with the lid. In addition, by folding a part or all of the lid body and storing it in the concave portion, the size of the space forming the compartment of the storage portion can be changed, and thereby a plurality of sizes can be obtained. This is a positioning and fixing structure that can be positioned and fixed at a predetermined position when a different second device is fitted into the recess.
