The description about the arrangement of the antenna unit 32 in the description of FIG. 4 may be regarded as the description about the arrangement of the antenna element 132.

  FIG. 14 is a block diagram showing an example of the configuration of the signal processing system of the mobile phone 1. The cellular phone 1 includes a CPU 141, a memory 142, a communication processing unit 143, an antenna element 132, an audio processing unit 144, a microphone 63, a speaker 145, an open / close detection unit 146, push switches 91 and 53, a main display unit 21, and a sub display unit 22. , Drive units 147 and 52 are provided.

  The CPU 141 and the memory 142 are configured as, for example, an IC provided on the circuit board 31, and perform predetermined calculations based on signals from various means and execute control of various means.

  The communication processing unit 143 includes a high-frequency circuit 61, and modulates various data such as audio data and image data processed by the CPU 141 in order to perform wireless communication using radio waves, via the antenna element 132. To send. Further, the communication processing unit 143 demodulates the signal received via the antenna element 132 and outputs the demodulated signal to the CPU 141.

  The audio processing unit 144 converts audio data from the CPU 141 into an audio signal and outputs the audio signal to the speaker 143, and converts an audio signal from the microphone 63 into audio data and outputs the audio data to the CPU 141.

  The open / close detection unit 146 is configured as a switch that outputs an ON signal to the CPU 141 when the angle between the first housing 2 and the second housing 3 is equal to or greater than a predetermined value, for example.

  The drive units 147 and 52 control the main display unit 21 and the sub display unit 22 based on signals from the CPU 141, respectively. The drive unit 147 is configured by, for example, an IC provided on the circuit board 44 and is provided at a position that does not overlap the antenna element 132 in the closed state.

  According to the mobile phone 1 described above, in the closed state, an element that has a relatively small influence on the antenna characteristics is arranged near the antenna element 132, and an element that has a relatively large influence on the antenna characteristics is an antenna element. Since it is arranged away from 132, the influence of the second housing 3 on the antenna characteristics in the closed state is mitigated as compared with the conventional mobile phone.

  That is, even when the sub display unit 22 is arranged at a position overlapping the antenna element 132 and the antenna element 132 is provided in the end 2b of the first housing 2, the sub display unit 22 and the antenna element 132 interfere with each other. In order to reduce this as much as possible, the space inside the end portion 3b of the second housing 3 facing this can be used effectively. In other words, it is possible to arrange the sub display unit 22 on the end 3b side while forming the outer shapes of the housings 2 and 3 so that the open / close side ends 2b and 3b coincide with each other. The degree of freedom is improved.

  Since the back surface of the sub display holder 51 is provided in contact with the back surface of the main display frame 42, the sub display holder 51 is stably fixed, and the structural strength of the sub display holder 51 is supported by the main display frame 42. Is also reinforced.

  Since the driving part 52 is provided on the tongue piece 51b, the flexible wiring board does not turn up in the manufacturing process as compared with the conventional case where the driving part is provided on the flexible wiring board connected to the sub display part. , Make the work easier. In addition, the degree of freedom of three-dimensional component layout is improved.

  Since the pressing switch 53 is provided on the tongue piece 51b, the distance between the back surface of the second housing 3 and the pressing switch 53 is short. Therefore, even if the thickness of the housing is somewhat large, it is not necessary to increase the push button 23 in the pressing direction or to raise the pressing switch 53. Further, since the tongue 51b is provided at a position that does not overlap the antenna element 132, the user's hand pressing the push button 23 is unlikely to affect the antenna characteristics of the antenna element 132.

  Since the sub display portion 22 has a chamfered portion that overlaps with the antenna element 132, the influence of the sub display portion 22 on the antenna characteristics of the antenna element 132 is reduced as much as possible.

  The wireless communication terminal of the present invention is not limited to the above embodiment, and may be implemented in various aspects.

  The wireless communication terminal that can be opened and closed is not limited to the folding type as in this embodiment. It is only necessary that the respective casings can move relative to each other between a closed state in which two or more casings are overlapped with each other and an open state in which at least some of the portions facing each other in the closed state are exposed. Therefore, for example, the first housing and the second housing are slid to each other by parallel movement or rotational movement to open and close.

  The base on which the back surface of the first display unit abuts may be only a member that holds the first display unit, or may include a member that is attached to the member. In the above-described embodiment, the main display unit holder 41 and the main display frame 42 correspond to the base body of the present invention.

  As long as the second display unit is provided so as to be stacked on the base, the second display unit itself may contact the base, or a holder that holds the second display unit may contact the base. Good. Further, the shape and size of the portion in contact with the substrate are not limited. Preferably, as in the above-described embodiment, the surfaces abut over a predetermined area (for example, an area that is half or more of the second display unit).

  The shield body is not limited to a case shape. For example, it may be a plate having no partition.
