Description

  The present invention relates to a portable electronic device having a structure in which a battery pack and an electronic card medium are detachably attached to a device body.

  In portable electronic devices such as mobile phones, there are products that are used with a battery pack and an electronic card medium mounted on the device body. For example, there are battery packs and mobile phones that are used with a SIM card as an electronic card medium.

  If the SIM card is inserted or removed while the power of the device main body is on, a failure such as loss of stored data may occur.

  In order to prevent this, a mechanism is provided in which the SIM card cannot be attached or detached while the battery pack is attached. For example, Japanese Patent Application Laid-Open No. 2004-126877 (Patent Document 1) describes a portable electronic device in which a battery pack is mounted so as to cover the upper side of a SIM card.

  Also, a portable electronic device that is used with a SIM card attached cannot read / write the contents of the SIM card if the user inserts the SIM card in the device body by mistake in the front / back / front / rear / left / right orientation. Therefore, Patent Document 1 describes a configuration for preventing such erroneous mounting. That is, Patent Document 1 describes that a stopper having a recess having the same shape as a notch included in a SIM card is provided as a mark for mounting the SIM card.

JP2004-126877

  However, with this configuration, it is not possible to completely prevent the user from mistakenly attaching the SIM card. For example, when the user installs a SIM card in the dark, the concave portion that serves as the mark may not be confirmed.

  Further, since the battery pack covers the upper part of the installed SIM card, the user may not be aware of the wrong installation of the SIM card.

  Users often notice this mis-installation when the function of using the SIM card cannot be executed. If the user notices that the SIM card is incorrectly installed after the battery pack is installed, the user must first turn off the power, remove the battery pack, and then reinstall the SIM card. .

  Moreover, since the SIM card and the battery pack are arranged one above the other in the configuration of Patent Document 1, the thickness of the device main body is increased.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a thin portable electronic device that reliably prevents an electronic card medium from being erroneously attached.

The present invention
A portable electronic device in which an electronic card medium and a battery pack can be freely attached to and detached from the device body.
An electronic card medium having a notch at one corner;
A protrusion that engages with the notch, an electronic card medium mounted on the device main body, and a battery pack mounted at a position aligned in the longitudinal direction of the portable electronic device;
A portable electronic device is provided.

  The present invention provides the following effects.

  In the portable electronic device according to the present invention, when the electronic card medium is erroneously attached, the user cannot attach the battery pack. Therefore, the user can check the mounting state of the electronic card medium at the stage of mounting the battery pack. Further, this portable electronic device reliably prevents the power from being turned on in a state where the electronic card medium is erroneously attached.

  Further, in the portable electronic device according to the present invention, since the battery pack and the electronic card medium are arranged on the same plane, the thickness of the device main body is thinner than the portable electronic device disclosed in Patent Document 1.

  Next, embodiments of the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a perspective view showing the configuration of the mobile phone 1 according to the first embodiment of the present invention. However, portions not related to the present invention are not shown.

  The SIM card 200 is formed in a rectangular planar shape with one corner cut into a triangular shape. Further, the SIM card 200 includes an IC chip terminal 202 on the lower surface.

  The battery pack 100 is formed in a flat rectangular parallelepiped shape that is larger than the SIM card 200. The battery pack 100 also includes a protrusion 101 that engages with the notch 201 of the SIM card 200 and a battery terminal 102.

  In the mobile phone 1 of FIG. 1, the battery pack 100 and the SIM card 200 are detachably attached to the device main body 300.

  Therefore, the device main body 300 includes a SIM card holding mechanism 303 on which one end of the SIM card 200 is slidably mounted from the upper right direction to the lower left direction in FIG. In addition, the device main body 300 has a battery pack holding unit 301 in which the battery pack 100 is detachably mounted from above in FIG. 1 at a position where the other end of the SIM card 200 (the notch 201 side of the SIM card 200) is held. Have

  The SIM card holding mechanism 303 is formed in a shape in which one end of the SIM card 200 is inserted on the substrate 302 disposed on the device main body 300. Further, the SIM card holding mechanism 303 includes an IC chip terminal connector 304 that is electrically connected to the IC chip terminal 202 therein.

  The battery pack holding part 301 is formed on the device main body 300 as a recess into which the battery pack 100 is inserted.

  The battery terminal connector 305 is disposed on the substrate 302.

  In the configuration as described above, the battery pack 100 and the SIM card 200 can be detachably attached to the mobile phone 1 of the present embodiment.

  FIG. 2 is a perspective view showing a state in which the battery pack 100 and the SIM card 200 are correctly attached. FIG. 3 is a plan view showing the same state as FIG.

  As shown in FIGS. 2 and 3, when the SIM card 200 is correctly attached to the SIM card holding mechanism 303, the battery pack 100 is detachably attached to the battery pack holder 301. Then, the protrusion 101 engages with the notch 201 and the battery terminal 102 is connected to the battery terminal connector 305. In this state, the user cannot attach or detach the SIM card 200.

  FIG. 4 is a cross-sectional view of the mobile phone 1 as viewed from the side, showing a state where the user intends to attach the SIM card 200 with the battery pack 100 attached. In this case, since the battery pack 100 and the protruding portion 101 prevent the SIM card 200 from being inserted into the SIM card holding mechanism 303, the user cannot attach the SIM card 200.

  FIG. 5 shows a case where the user erroneously inserts the SIM card 200 by rotating it 180 degrees on the card plane. In this case, the notch 201 does not exist at a position where it engages with the protrusion 101. For this reason, the user cannot wear the battery pack 100. The same applies when the user erroneously attaches the SIM card 200 upside down.

  As described above, in the mobile phone 1 according to the present embodiment, when the SIM card 200 is erroneously attached, the user cannot attach the battery pack 100. Therefore, at this stage, the user can surely notice that the SIM card 200 is erroneously attached. Further, since the battery pack 100 cannot be mounted, it is possible to prevent the power from being turned on when the SIM card 200 is erroneously mounted.

  Further, the user cannot attach or detach the SIM card 200 in a state where the battery pack 100 is attached. For this reason, it is possible to prevent the SIM card 200 from being attached or detached while the power is on and causing a failure.

  Further, since the battery pack 100 and the SIM card 200 are arranged on the same plane, the mobile phone 1 of the present embodiment has a thinner device body than the mobile electronic device disclosed in Patent Document 1.

  Note that the SIM card widely used today is formed in a rectangular planar shape with one corner cut into a triangular shape, like the SIM card 200 of the present embodiment. That is, the above-described effects are realized by using the SIM card widely used today as it is. The same applies to other embodiments.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.

  In the first embodiment of the present invention, the shape of the protrusion 101 is the same triangular shape as the shape of the notch 201. However, in order to realize the main effect of the present invention, that is, prevention of erroneous mounting of the electronic card medium, the protrusion may not have the above-described shape.

  FIGS. 6A, 6B, and 6C are plan views showing examples of other shapes of the protrusions in the second embodiment of the present invention. The apparatus configuration of this embodiment is the same as that of the first embodiment except for the difference in the shape of the protrusions.

  In FIG. 6A, the protrusion 101 a is formed in a semicircular shape whose tip shape is in contact with the notch 201 of the SIM card 200.

  In FIG. 6 (b), the protrusions 101 b and 101 c are formed in a plurality of pins whose respective tips are in contact with the notch 201 of the SIM card 200.

  In FIG. 6C, the protruding portion 101 d is formed in a shape surrounding the end portion of the SIM card 200 on the notch portion 201 side.

  FIG. 7 is a plan view showing a positional relationship between the battery pack 100 and the SIM card 200 in a state where the battery pack 100 is attached to the device main body 300. The projections in this embodiment occupy all or part of the space in the region X in FIG. 7, that is, the portion cut into a triangular shape, and the space in the region Y, that is, the position where the SIM card 200 is mounted. Any shape other than the shape shown in FIG.

  As described above, the embodiment of the present invention has been described by taking as an example a mobile phone using a SIM card and a battery pack.
