  The connection between the mobile phone and the battery pack requires a stable connection, and at the time of design, fitting adjustment is performed so as to prevent the battery pack from rattling in the battery case 32 to suppress the rattling. Therefore, the fitting with the battery pack 34 in the battery casing 32 tends to be hard, and when the user needs to remove the battery pack 34 from the battery casing 32, it takes time to remove the battery pack. There is.

  FIG. 8 shows an operation procedure when the user removes the battery pack 34 stored in the battery case 32 of the mobile phone case 31 shown in FIG. 7, and the user starts from the state where the battery pack 34 is stored in the battery case 32. When the battery pack 34 is removed, first, the battery cover 35 is pulled out by sliding the battery cover 35 in the direction of the arrow while pressing the upper surface with a finger (s1), thereby releasing the fitting with the mobile phone case 31. Then, the battery cover 35 is removed (s2), and then the battery pack 34 and the battery case 32 are disengaged by lifting the battery pack 34 by hooking a finger or a nail on the finger hooking projection 36 of the battery pack 34. An operation of taking out the bag 32 is performed (s3).

  At this time, if the battery pack 34 is hard to be fitted in the battery case 32, the battery pack 34 cannot be easily detached from the battery case 32, and the finger hooking projection 36 of the battery pack 34 is damaged due to forcible removal. There are concerns that the user's fingers and nails will be damaged.

  On the other hand, in the battery holding structure described in Patent Document 2, if the hook mechanism provided on the case is slid, the battery locking mechanism is released, and then the support for holding the battery pack is provided by the spring biasing force. Since the battery is rotated in a direction in which the battery can be taken out from the battery storage unit, the battery stored in the battery storage unit can be easily taken out without causing the above-mentioned concerns. In the battery holding structure described in 2 above, a slide and hook mechanism that requires a large number of spring members and a mechanism that urges the battery in a direction in which the battery can be taken out when the lock is released must be provided. However, there is a problem that the configuration is complicated and the manufacturing cost is increased accordingly.

  Furthermore, in the invention described in Patent Document 2, since the biasing force of the spring is used, if the biasing force of the spring is too strong, the battery jumps out of the case from the support due to the rotating momentum of the support when the hook mechanism is released. There is a concern that it may be dropped inadvertently, and there is also a problem that if the biasing force of the spring becomes weak due to secular change, the support will not rotate in a direction where the battery can be taken out.

  In view of the above problems, an object of the present invention is to provide a means that allows a battery pack stored in a battery storage portion of a portable electronic device case to be easily removed with a relatively simple configuration. is there.

  The present invention provides a battery pack housing part structure for a portable electronic device case comprising a case having a battery pack housing part and a battery cover that is detachably fitted to the case and covers an opening of the battery pack housing part. The battery pack housed in the battery pack housing portion is pushed out from the battery pack housing portion in conjunction with the movement of the battery cover when the fitting between the case and the battery cover is released. It has the battery pack extrusion mechanism which performs operation | movement.

  The battery pack push-out mechanism includes a slider that has a function of pushing the bottom surface of the battery pack that is pushed out while being slid into the battery pack housing portion and is housed in the battery pack, and the slider when the battery cover is moved. The slider can be configured by a rib provided on the battery cover having a function of pushing the slider into the battery pack housing portion.

  At this time, the rib has a function of pushing the slider from the side wall surface of the battery pack housing portion into the battery pack housing portion, and the slider is pushed out from the side wall surface into the battery pack housing portion. This can be realized by a configuration in which a slope is formed to push up the bottom surface of the battery pack housed in the battery pack.

  Further, as another form of the battery pack push-out mechanism, a lever part and a lift part integrally formed in an L-shaped cross section that is turned around a shaft fixed in a frame of the battery pack storage part, and the battery It can also be realized by a configuration including a protrusion provided on the battery cover having a function of rotating the lift part into the battery pack housing part by contacting the lever part when the cover is moved.

  In that case, the said lift part can be implement | achieved as a structure which has a function which pushes up the bottom face of the battery pack accommodated in the said battery pack accommodating part in response to rotation operation by the said projection part.

  In addition, the battery pack is provided with a fitting protrusion that fits into a fitting groove provided in the battery pack storage portion when the battery pack is stored in the battery pack storage portion. The battery pack pusher mechanism pushes up the battery pack from the battery pack housing portion so that the battery pack and the battery pack housing can be accommodated. It is realizable as a structure which has the function to remove the said fitting between parts.

  In the present invention, when the battery cover is slid to remove the battery cover fitted to the mobile phone case, the battery pack is pushed up from the bottom surface of the battery pack storage portion by a simple mechanism configured inside. Since the battery pack and the battery pack storage unit are disengaged, the user can easily remove the battery pack from the battery pack storage unit after removing the battery cover. become able to.

  If the present invention is applied, the action of pushing out the battery pack from the battery pack storage portion by the movement of the battery cover when removing the battery cover works, so that it becomes easy to remove the battery pack from the battery pack storage portion, User convenience can be improved.

  In addition, the present invention provides a slider or lever and a lift part that act as a force for pushing out the battery pack from the battery pack housing part, and a force that allows the user to move the battery cover to remove the battery cover is applied to the slider or lever. Since it is configured to act, it can be realized with a simple configuration in which the battery cover is provided with a member that contacts the slider or lever, and the cost can be reduced. Furthermore, since it is not the structure which uses the biasing force of a spring, there is almost no influence on a function by secular change.

  Furthermore, it is not necessary to provide the battery pack with a finger hooking projection for taking out the battery pack from the battery pack storage portion, so that the configuration of the battery pack is simplified.
