Description

  The present invention attaches a memory card, particularly a SIM (Sabscriber Identity Module) card, to a portable terminal device or the like, and remarkably simplifies the structure for removing the card, thereby reducing the manufacturing cost and facilitating the card exchange operation. The present invention relates to a card fixing structure that can be used and a portable terminal device using the same.

  In recent years, the use of a memory card, which is a small information recording medium with a built-in solid-state memory, is widely used in various portable terminal devices such as mobile phones and PDAs.

  In particular, a SIM card records contractor information issued by a mobile phone company or the like, and this SIM card is inserted into a mobile terminal device or the like and used for user identification. On the other hand, in recent years, there has been developed from a SIM card so that private information such as a telephone directory and personal identification information for credit repayment can be encrypted and registered in addition to the contractor information. It is called USIM (Universal SIM) card.

  In most cases, the above-mentioned SIM card is used while being inserted into the mobile terminal device, and there is almost no need to replace the SIM card.

  Therefore, it is desirable that the structure for fixing the SIM card to the portable terminal device should be as simple as possible and have as little space as possible if the SIM card can be securely fixed and the SIM card can be replaced relatively easily. It is.

  As a structure for holding the SIM card in the portable terminal device, there are various methods such as a method of using a connector having a card holding structure or a method of adding a new part for the purpose of holding the card. For example, as in Patent Document 1, a structure has been proposed in which a card can be easily removed when the battery pack is removed by operating a slide lever for removing the battery pack.

  In addition, some connectors having a card holding structure have only a temporary holding function. In that case, it is necessary to provide a separate mechanism for holding the book.

In addition, as a holding method that does not use a slide, there is a method in which the card is bent and attached to the card fixing groove while being removed.

That is, if the thickness and material of the rib 9 allow the flexibility of the rib 9 to be increased, the protrusion amount of the protrusion 20 can be increased.

  The operation of the above embodiment will be described below.

  When the card 14 (SIM card) is received in the card receiving recess 15 formed in the bottom of the battery receiving space 6, one end 14 a of the card 14 is positioned below the locking projection 19 as shown in FIG. Then, the card 14 is inserted into the card housing recess 15, and then the other end 14 b side of the card 14 is pressed so as to be pushed into the card housing recess 15 as indicated by an arrow A. Then, the other end 14b of the card 14 comes into contact with the protrusion 20, but the other end 14b of the card 14 has a curved surface so that the upper surface of the protrusion 20 is smoothly lowered toward the card receiving recess 15. The rib 9 having the protrusion 20 is deformed outward within the flexible range of the rib 9 as shown by an arrow B in FIGS. Thus, the card 14 is received in the card receiving recess 15 against the elastic force of the spring contact 17.

  When the other end 14b of the card 14 is received in the card receiving recess 15, the protrusion 20 protrudes on the other end 14b of the card 14 due to the elasticity of the flexible lock portion 21, as indicated by an arrow B 'in FIG. Accordingly, the card 14 is securely held by the locking projection 19 and the projection 20 without jumping out of the card housing recess 15. At this time, the card 14 is connected to the substrate 18 via the spring contact 17.

  In a state where the card 14 is housed and held in the card housing recess 15, the battery 7 is housed in the battery housing space 6 as shown in FIG. 2, the connector 7a is connected to the connecting portion 7b, and the back surface of the battery 7 (not shown) is shown. In this state, the cellular phone 1 is used.

  For example, if the card 14 is a SIM card, information (telephone number and mail address) on the user acquired from the card 14 is authenticated by a control unit (not shown) mounted on the board 18. Communication is performed using the antenna 12. If the card 14 is a recording medium, the control unit records information that can be communicated using the antenna 12 on the card 14.

  When removing the card 14, after removing the battery 7 as shown in FIG. 2, the flexible lock portion 21 in the rib 9 provided with the protrusion 20 is moved to the arrow B as shown in FIGS. 4 and 5.
