DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite wireless portable terminal provided with a wireless portable terminal circuit having a function of wirelessly communicating data such as voices and characters, and a pager circuit for wirelessly receiving a selective calling signal. More particularly, the present invention relates to a composite wireless portable terminal device which ensures convenience for a user by, for example, preventing interference due to high frequency or the like occurring between a wireless portable terminal circuit unit and a pager circuit unit.

2. Description of the Related Art Generally, in a wireless portable terminal such as a portable telephone terminal, data such as voice and text is bidirectionally wirelessly communicated, so that communication between users is easy. There is an advantage that can be obtained. On the other hand, in such a wireless portable terminal, it is necessary to register the position of the own terminal every time the terminal passes through the boundary of the service zone of the base station. There is a problem that a large amount of is consumed. In other words, when moving the mobile wireless terminal in the reception standby state for a long time,
Actually, there is a disadvantage that a large amount of power is consumed even if the user does not use the terminal.

[0003] Further, for example, a pager wirelessly receives a selective calling signal transmitted from a transmitting side, and such a pager is generally usable over a wide area because of a large service area. In addition, since such a pager does not perform the above-described transmission operation such as the position registration, there is an advantage that power consumption can be suppressed even if the reception standby state is maintained for a long time. . However, such a pager does not have a transmission function and thus cannot perform two-way communication, and has a problem that the amount of data that can be received at one time is small.

Under the circumstances described above, for example, one user may carry both a wireless portable terminal and a pager, and it is desired to develop a device having both functions of the wireless portable terminal and the pager. Was rare. In other words, by integrating the wireless portable terminal having the advantages and disadvantages and the pager into a single housing, for example, in the reception standby state, while receiving the selective call signal from the caller by the pager function, In this way, it is possible to respond to the caller by the wireless portable terminal function using the telephone number data and the like notified from the caller. In other words, the power supply to the wireless portable terminal function may be stopped during the reception standby state, and the above-described drawbacks of the wireless portable terminal and the pager can be avoided because the power consumption can be reduced. Can be covered.

For example, Japanese Patent Laid-Open No. 5-91 discloses a composite wireless portable terminal device in which a wireless telephone circuit having a portable telephone function and a wireless pager circuit having a pager function are integrated.
A mobile phone device with a pager function described in Japanese Patent Publication No. 022 is known. Here, the appearance of this device is shown in FIG.
It is shown in FIG. The mobile phone device with a pager function shown in the figure is composed of a main unit 31 having an audio output speaker 34 of a radio telephone circuit unit, and a lid unit 32 having an audio input microphone 35 of the radio telephone circuit unit. These units 31 and 32 are foldably connected.

The main unit 31 has a switch 33.
When both the units 31 and 32 are folded, the switch 33 detects the closed state, and based on this detection, the power supply to the wireless telephone circuit is cut off. . As described above, in the above-described portable telephone device with a pager function, when both the units 31 and 32 are folded, the power supply to the wireless telephone circuit unit is cut off to give priority to the pager function. Thus, the amount of power consumed by the device can be reduced.

In the case where the wireless portable terminal circuit section having the wireless portable terminal function and the pager circuit section having the pager function are integrated as described above, interference between these two circuit sections due to high frequency or the like is caused. Is known to occur, and it is known that the quality of data transmission during transmission processing and reception processing is reduced due to such interference. That is, for example, when the above-described two circuit units are provided at positions that are extremely close to each other, and power is supplied to both of these circuit units, the space between these two circuit units may be caused due to high frequency wraparound. Causes mutual interference,
This causes a problem that an oscillation state occurs in these circuit units.

For this reason, for example, as shown in FIG. 27, an internal mounting example of a composite wireless portable terminal device 41 shown in FIG. 26 is provided between a wireless portable terminal circuit section 43 having an antenna 42 and a pager circuit section 44. Powerful shield 4 to block
6, the interference described above is prevented. Also, for example, as shown in FIG. 28, by increasing the size of the housing constituting the device 41 and physically separating the distance between the antenna 42 of the wireless portable terminal circuit 43 and the pager circuit 44 by In order to prevent the above-mentioned interference, it has been performed. The device 41 shown in FIGS. 27 and 28 includes the wireless portable terminal circuit unit 4.
3 and a power supply 45 for supplying power to the pager circuit unit 44 are shown.

[0009]

However, in the composite wireless portable terminal device having the above-described wireless portable terminal circuit section and pager circuit section, interference due to high frequency and the like generated between these two circuit sections is, for example, complex. Since the size of the wireless portable terminal device is increased and the distance between these two circuit units is prevented by physically separating the two, the size of the device becomes larger, which makes it difficult for a user to use the device. However, there has been a problem that the cost of the housing constituting the device increases.

[0010] Such a problem has not yet been solved by the portable telephone device with a pager function shown in FIG. That is, the main unit 3 of this device
1 and the lid unit 32 are closed, the supply of power to the wireless telephone circuit is cut off, so that the above-mentioned interference does not occur. However, when both the units 31, 32 are open, the wireless telephone Since power is supplied to both the circuit unit and the wireless pager circuit unit, a shield or the like must be provided between the two circuit units to prevent the above-described interference.

In the portable telephone device with a pager function shown in FIG. 25, for example, when the closed state is detected as described above, the supply of power to the radio telephone circuit is cut off. Since the power supply is not controlled when the unit 32 is opened, in such a case, it is necessary to supply power to the wireless telephone circuit unit by, for example, a user operation. There is a demand for further improving the convenience for the user. Further, in this device, since the speaker for outputting the sound of the radiotelephone circuit unit and the speaker for outputting the ringing sound of the pager circuit unit are configured separately, the cost for these speakers increases, and from this point of view. There was a demand to reduce costs.
