[0004]
[Problems to be solved by the invention]
However, according to the above-mentioned conventional portable terminal device, a connector having an IC card terminal for contacting a connection terminal of an IC card and a battery terminal for contacting a connection terminal for power supply of a battery are formed on the main body. A connector is provided. Therefore, there are problems that the number of components is large, the cost of the portable terminal device is increased, and the space for both connectors is required, and the portable terminal device becomes large.
[0005]
An object of the present invention is to provide a portable terminal device that can reduce costs and reduce the size.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides an IC card capable of contacting a connection terminal of an IC card in a portable terminal device to which power is supplied by mounting a battery having an IC card holding portion for holding an IC card in a main body. A connector in which a battery terminal and a battery terminal contacting a connection terminal of the battery are integrally formed is provided on the main body.
[0007]
According to this configuration, the connector having the terminal for the IC card and the terminal for the battery is mounted on the circuit board in the main body. When the IC card is mounted on the IC card holding portion of the battery and the battery is mounted on the main body, the connection terminal of the battery contacts the terminal for the battery, and the connection terminal of the IC card contacts the terminal for the IC card. As a result, power is supplied to the mobile terminal device, and a GSM mobile phone service using SIM can be used.
[0008]
When some terminals such as the GND terminal of the IC card terminal and some terminals such as the GND terminal of the battery terminal are electrically connected in the connector, the land portion on the circuit board to which the connector is connected can be reduced. When the IC card terminal is arranged closer to the outer peripheral surface of the main body than the battery terminal, the IC card holding portion is opened facing the outer peripheral surface of the battery so that the IC card can be attached and detached with the battery mounted. It can be carried out.
[0009]

[0012]
The connector 12 is provided with a battery terminal 13 and an IC card terminal 14 so as to be electrically connected to predetermined land portions 15 and 16. The connection terminals 21 and 31 of the battery terminal 13 and the IC card terminal 14 come into contact with each other when the battery 20 is mounted on the main body 10.
[0013]
In the mobile phone 1 having the above configuration, when the IC card 30 is mounted on the battery 20 and the battery 20 is mounted on the main body 10, the connection terminal 21 of the battery 20 and the battery terminal 13 of the connector 12 come into contact with each other. Is supplied with power. As a result, the mobile phone 1 can transmit and receive a telephone call and e-mail.
[0014]
Further, the connection terminal 31 of the IC card 30 and the IC card terminal 14 of the connector 12 come into contact with each other, so that power is supplied to the IC card 30 and communication with the IC card 30 is enabled. Thus, the IC card 30 can be used. For example, when a SIM or UIM is mounted as the IC card 30, a mobile phone service such as GSM or IMT-2000 can be used. When a PC card such as a memory card is mounted as the IC card 30, data stored in the PC card can be retrieved.
[0015]
According to the present embodiment, since the IC card terminal 14 and the battery terminal 13 are formed integrally with the connector 12, the number of components can be reduced and the cost of the mobile phone 1 can be reduced. Further, the IC card terminal 14 and the battery terminal 13 can be arranged in a space-saving manner, and the size of the mobile phone 1 can be reduced.
[0016]
Next, FIG. 4 is a plan view showing the connector 12 of the mobile phone according to the second embodiment.
For the sake of convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals. In the present embodiment, the GND terminal (ground terminal) 13a of the battery terminal 13 and the GND terminal 14a of the IC card terminal 14 are electrically connected in the connector 12. Other parts are the same as in the first embodiment.
[0017]
According to the present embodiment, the same effect as that of the first embodiment can be obtained, and the number of the land portions 15 or 16 to which the connector 12 is attached can be reduced. Therefore, the size of the circuit board (not shown) can be reduced, and the size of the mobile phone 1 can be further reduced. Note that one of the battery terminals 13 other than the GND terminals 13a and 14a and one of the IC card terminals 14 may be electrically connected within the connector 12.
[0018]
Next, FIG. 5 shows a rear perspective view of the mobile phone according to the third embodiment, and FIG. 6 shows a perspective view of the battery 20 of the mobile phone 2. For the sake of convenience of explanation, the same parts as those in the first embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals. In the mobile phone 2 of the present embodiment, the connector 12 is provided near the bottom surface 10 a of the main body 10.
[0019]
The connector 12 has an IC card terminal 14 disposed on a side closer to the bottom surface 10a, and a battery terminal 13 disposed on a side farther from the bottom surface 10a. Further, an IC card holding portion 22 provided on the battery 20 is formed on an end surface on the side of the bottom surface 10a so as to face the opening 22a. Other parts are the same as in the first embodiment.
[0020]
According to the present embodiment, the opening 22a of the IC card holding unit 22 is exposed when the battery 20 is mounted on the main body 10. Therefore, the IC card 30 can be attached and detached through the opening 22a without detaching the battery 20 from the main body 10. Therefore, in addition to the same effects as those of the first embodiment, when a plurality of IC cards 30 are used, attachment / detachment of the IC cards 30 can be facilitated, and usability of the mobile phone 2 can be improved.
[0021]
Although the IC card holding portion 22 is opened toward the bottom surface 10 a, it may be opened toward the outer peripheral surface of the battery 20. Further, similarly to the second embodiment, one terminal of the battery terminal 13 and one terminal of the IC card terminal 14 may be electrically connected in the connector 12.
[0022]
In the first to third embodiments, the mobile phone has been described. However, the same effect can be obtained by the same configuration in other mobile terminal devices such as PHS, PDA, and portable game machine.
[0023]
