Description

  The present invention relates to a portable electronic device such as a cellular phone.

In mobile phones as portable electronic devices, the housing has been downsized (thinned, down in the surface direction perpendicular to the thickness direction, etc.).
On the other hand, in a mobile phone as a portable electronic device, a card (hereinafter also referred to as an “authentication card”) for authenticating an individual such as a UIM card (User Identity Module Card) or a SIM card (Subscriber Identity Module Card) is included. Must be worn on the body. Therefore, generally, a card holder that holds an authentication card is provided inside the housing (see, for example, Patent Document 1 below).

JP 2008-287651 A

However, although authentication cards such as UIM cards and SIM cards are small in size, since the card holder holds the authentication card, the size is naturally larger than the authentication card. Such a card holder is relatively large in size with respect to the housing, and hinders downsizing of the housing. Further, in a mobile phone, it is necessary not only to reduce the size of the housing but also to ensure the detachability of the authentication card with respect to the housing (card holder).
The above-mentioned problems may occur in portable electronic devices other than mobile phones as well.

  Accordingly, an object of the present invention is to provide a portable electronic device that can achieve downsizing of the casing while ensuring the detachability of the authentication card with respect to the casing.

  The present invention is a housing having a longitudinal direction, a lateral direction, and a thickness direction, the first surface extending along a plane including the longitudinal direction and the lateral direction, and a plane including the longitudinal direction and the thickness direction. And the second surface is adjacent to the first surface in the lateral direction, and the battery is accommodated through an opening formed across the first surface and the second surface. A housing having a battery housing recess, and a second opening that is mounted in the lateral direction with respect to the housing and that opens to the first surface side and the second surface side of the opening. A card that has a battery cover member that covers both the opening and a card insertion hole into which the authentication card is inserted through the second opening, and holds the authentication card inserted in the short direction into the card insertion hole A battery lid member, A portable electronic device holder authentication card is attached to the housing in a state of being held.

  Moreover, it is preferable that the said battery is accommodated in the area | region including between the said card holder and the said battery cover member in the said battery accommodating recessed part.

  Further, the battery cover member functions as a stopper for preventing the authentication card from coming into contact with or close to the authentication card held by the card holder at a position facing the card insertion hole in a state of being mounted on the housing. It is preferable to have a retaining portion for preventing the above.

  Further, the case further includes a main circuit board having a maximum area along a plane including the longitudinal direction and the short side direction inside the case, and the card holder is configured when the case is viewed in the thickness direction. The main circuit board is preferably disposed at a position adjacent to the main circuit board.

Therefore, it is possible to realize a configuration in which the battery Q is sandwiched between the card holder 80 and the battery lid 90 in the thickness direction D3. For example, a member that sandwiches the battery Q in the thickness direction D3 can be reduced.

  Further, in the mobile phone 1 according to the present embodiment, the battery lid 90 has a retaining portion 93 at a position facing the card insertion hole 83 in a state where the battery lid 90 is mounted on the operation unit side body 2. Therefore, it is possible to prevent the authentication card ID once held (attached) to the card holder 80 of the operation unit side body 2 from being removed from the card holder 80, and for example, it is possible to prevent the authentication card ID from being momentarily interrupted.

  Further, in the mobile phone 1 of the present embodiment, the card holder 80 is located adjacent to the main circuit board 70 without overlapping the main circuit board 70 when the operation unit side body 2 is viewed in the thickness direction D3. Placed in. Therefore, since the card holder 80 is disposed in an area where the main circuit board 70 is not disposed, the thickness (length in the thickness direction D3) of the operation unit side body 2 can be suppressed.

As mentioned above, although one Embodiment of this invention was described, this invention is not restrict | limited to embodiment mentioned above, It can change suitably.
For example, the second surface of the housing according to the present invention is configured by the right side surface 2c of the operation unit side body 2 in the embodiment, but is not limited thereto. The left side surface 2d may be configured.

  In addition, the portable electronic device of the present invention is not foldable as in the above-described embodiment, and one case is slid in one direction from the state where the operation unit side case 2 and the display unit side case 3 are overlapped. It may be a slide-type portable electronic device. Further, the portable electronic device of the present invention is a rotary type (turn type) in which one casing is rotated around an axis line along the overlapping direction of the operation unit side casing 2 and the display unit side casing 3. It may be a portable electronic device. In addition, the portable electronic device of the present invention may be of a type (straight type) in which the operation unit side body 2 and the display unit side body 3 are arranged in one housing and do not have a connecting part. The portable electronic device of the present invention may be a so-called biaxial hinge type that can be opened and closed and rotated.

  The present invention can be applied to portable electronic devices other than cellular phones. Examples of portable electronic devices other than cellular phones include PHS (registered trademark: Personal Handyphone System), portable game machines, portable navigation devices, PDAs (Personal Digital Assistants), and notebook computers.
