It is a matching circuit switching means.

Next, the operation will be described. First, the operation of using the mobile phone body 1 will be described. The camera unit 3 is mounted on the mobile phone main body 1, and the power of the mobile phone main body 1 is turned on. Normally, the camera is mounted so that the lens unit 4 of the camera unit 3 faces the user of the mobile phone. In addition, it is also possible to attach the camera unit 3 during a call. When the operation button of the camera (not shown) of the mobile phone body 1 is turned on, the power and the camera control signal are transmitted by the non-contact connector (not shown) of the mobile phone body 1 and the non-contact connector 10 of the camera section 3. Supplied to A video signal from the camera unit 3 is transmitted to the mobile phone main body 1 via the non-contact connector 10 or the like, and a video is displayed on the display unit 2. Note that, depending on the use mode, the image is not displayed on the display unit 2 but is transmitted to the mobile phone main body 1 of the other party via the antenna 20 and displayed on the display unit.

Further, the camera unit 3 is replaced in a call state,
It is also possible to reverse the shooting. Thus, not only the user of the mobile phone but also the surrounding scenery can be photographed. The temporary image may be interrupted when the camera unit 3 is replaced. At the time of the interruption, the image immediately before the interruption and the character indicating that the camera unit 3 is being replaced are transmitted to the other party and displayed. When the operation button of the camera (not shown) of the mobile phone body 1 is turned off, the power supply to the camera unit 3 is stopped, and the transmission / reception to the camera unit 3 is stopped, but the call can be continued. (Also, by turning off the power of the mobile phone 1, the operation of the camera unit 3 can be stopped without turning off the operation button of the camera (not shown) of the mobile phone 1.) Detachment from mobile phone body 1 is usually power off
However, as described above, it can be performed during a call.

As shown in FIG. 6, the presence or absence of the camera unit 3 is determined by the camera presence / absence determining means 21.
Since the matching circuits 22 and 23 can be switched by the matching circuit switching means 24 according to the determination result, optimum antenna characteristics can be obtained regardless of the presence or absence of the camera unit 3. When the camera section 3 is detached from the mobile phone main body 1 and used alone, a power supply can be secured by mounting the camera section 3 on the power supply device 14, as shown in FIGS.

Next, the operation of supplying power to the camera unit 3 and transmitting and receiving signals by the non-contact connector 10 and the like will be described. When an operation button of a camera (not shown) of the mobile phone main body 1 is turned on, a DC current from a battery of the mobile phone main body 1 flows into a chopper circuit (not shown), and is converted into an AC current having a frequency of about 500 kHz by the chopper circuit. . Then, as shown in FIG. 4, the AC converted current is passed through the inductor forming the non-contact connector 7 of the mobile phone main body 1, and the AC current is supplied to the non-contact connector 10 on the camera unit 3 side facing by the electromagnetic induction. Flows. This AC current is converted into DC by a rectifier circuit (not shown), and the power is used to drive a drive circuit of the camera unit 3 and the like. When a plurality of drive voltages for the camera unit 3 are required, it is possible to obtain different powers by winding a plurality of coils having different numbers of turns with the inductor on the camera unit 3 side (one voltage). May be stepped up and down by an electric circuit).

Then, the video signal and the clock signal of the camera section 3 are modulated by a predetermined modulation circuit, and converted into an AC signal of about 1 MHz, for example, as a non-contact connector 10 of the camera section 3.
To the inductor. Since current flows through the inductor of the non-contact connector 7 of the opposing mobile phone main body 1 due to electromagnetic induction, these signals are demodulated by the mobile phone main body 1 and used for display or transmission. The control signal of the camera unit 3 is transmitted and received in the same manner as the video signal. Since the non-contact connectors 7 and 10 are shielded by the metal thin film shield 18, deterioration of the electrical characteristics of the antenna 20 can be reduced.
In order to connect a power line and a signal line to the power coil 9a and the signal coil 9b, respectively, it is necessary to provide a through hole in the metal thin film shield 18. If the through holes are formed, the antenna current enters the metal thin film shield 18 via the power line and the signal line, and the antenna characteristics (efficiency and radiation pattern) deteriorate. Therefore, the power line and signal line are
A chip capacitor 19 having a resistance value of zero in a high frequency band used by the antenna is provided between these lines and the ground near the wire penetrating through the antenna 8, and the antenna current is caused to flow outside the metal thin film shield 18. To prevent intrusion.

As described above, according to the first embodiment, since the camera section 3 is detachably formed with respect to the mobile phone main body 1, both can be easily selected and used in accordance with the TPO, and the diversity of users can be improved. An effect that can flexibly cope with is obtained. In addition, by incorporating the non-contact connectors 7 and 10, mechanical and electrical reliability of the attaching / detaching portion can be ensured, and also an effect of securing reliability in a use environment such as moisture and dirt from the outside can be obtained. In addition, since the camera unit 3 is disposed on the upper surface of the mobile phone main body 1, it is possible to obtain an effect that the line of sight of the photographing screen becomes natural and the attachment and detachment of the camera unit 3 becomes easy. Further, by disposing the non-contact connector 7 on the upper surface of the mobile phone main body 1, an effect of easily securing a flat portion required for disposition can be obtained. In addition, since the camera section 3 can be replaced and inverted for shooting, it is possible to obtain an effect that not only the user of the mobile phone but also the surrounding scenery can be shot. In addition, an effect that optimum antenna characteristics can be obtained irrespective of the presence or absence of the camera unit 3 is obtained by the matching circuit switching unit 24 and the like. Further, since the non-contact connectors 7 and 10 are shielded by the metal thin film shield 18 and the ingress of the antenna current into the metal thin film shield 18 is prevented by the chip capacitor 19, the deterioration of the electrical characteristics of the antenna 20 can be reduced. Is also obtained. Further, since the camera section 3 is formed detachably with respect to the power supply device 14, an effect that the power supply can be easily secured even when the camera section 3 is detached from the mobile phone main body 1 and used alone is obtained.

As described above, in the first embodiment, the non-contact connector 7 is provided on the upper surface of the portable telephone body 1.
