BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a portable radio communication apparatus. More particularly, the present invention relates to a portable radio communication apparatus such as a portable telephone and the like.  
           [0003]    2. Description of the Related Art  
           [0004]    In recent years, in a portable telephone that has widely spread due to its convenience and the like, a call can be made from any location if it belongs to a service range. On the other hand, a call arrival tone gives a trouble to adjacent strangers during a meeting, during taking a train, during listening to a lecture meeting, or during listening to a concert. For this reason, traditionally, a portable telephone has been known for reporting a call signal arrival to a user of a portable telephone by using a vibration of a vibrator.  
           [0005]    However, the conventional portable telephone has the inconvenience that the user must always carry the portable telephone on the body, since the user need to feel the vibration of the vibrator, in order to report the call signal arrival by using the vibrator.  
           [0006]    Even if the user can know the call signal arrival from the vibrator without any trouble to a circumstance, if the user responds to the call signal arrival by saying a word during a meeting, during taking a train or the like, this consequently gives a trouble to the circumstance.  
           [0007]    Japanese Laid Open Patent Application (JP-A-Heisei, 8-149534) discloses the following portable information terminal. This has the configuration in which a portable information terminal body is separated from an external reporter. This identifies an attribute data added to an information received by the portable information terminal body, and outputs a report signal different for each kind of an information, to the external reporter by using an electric wave, an infrared ray or a supersonic wave, and changes an interval between on-off states of a reporter, such as an LED, a vibrator or the like in the external reporter, and a strength of an announcement or a vibration, in accordance with the report signal, and then reports the arrival of the information and the kind of the information to the user.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
       [0037]    An embodiment of the present invention will be described below with reference to the attached drawings. FIG. 1 shows a block diagram of an embodiment of a portable radio communication apparatus according to the present invention. This portable radio communication apparatus in the embodiment is provided with a portable telephone body  10  and a sub-apparatus  20 , in an example of a portable telephone. The portable telephone body  10  has a transmitter/receiver  11  for communicating with a partner terminal through a radio base station (not shown), a controller  12  and an easy radio device  13  for wirelessly communicating with the sub-apparatus  20 .  
         [0038]    Also, the sub-apparatus  20  is a portable call signal arrival display and response apparatus, such as a desk top type, a card type, or the like. It is provided with: an easy radio device  21  for wirelessly communicating with the portable telephone body  10 ; a controller  22 ; a light emission diode (LED)  23  for indicating a call signal arrival while emitting a light; a liquid crystal display (LCD)  24  for carrying out various indications; and a response switch  25  to be used at a time of a response. The portable telephone body  10  has components originally necessary for a telephone, such as a receiver unit and a transmitter unit and an operator used in a dial and a display section displaying an information such as a dial and an antenna and the like, although they are not shown.  
         [0039]    The operation of the embodiment in FIG. 1 will be described below by using a flowchart in FIG. 2 together with the views showing examples of displays of FIGS. 3A and 3B. When the portable telephone body  10  is at a wait state (Step S 1 ), if it receives a call signal (Step S 2 ), a call arrival signal is sent through the transmitter/receiver  11  to the controller  12 . At this time, if a call arrival tone gives a trouble to a circumstance, since a sub-apparatus operation switch (although its illustration is omitted, it is usually mounted in the sub-apparatus  20 ) is set on by a user, the controller  12  generates a display device illumination signal, on the basis of the input of the call arrival signal, in this case, and further sends the signal to the easy radio device  13  together with a caller information, as necessary. Accordingly, it is wirelessly transmitted as a sub-apparatus control signal to the sub-apparatus  20  (Step S 3 ). The sub-apparatus operation switch can be mounted in the portable telephone body  10 .  
         [0040]    The portable telephone body  10  and the sub-apparatus are located within a range where a radio communication can be done by using a weak electric wave. The easy radio device  21  in the sub-apparatus  20  receives a sub-apparatus control signal (including the caller information as necessary) wirelessly transmitted from the easy radio device  13  by using the weak electric wave (Step S 4 ), and sends it to the controller  22 . The controller  22  sends the display device illumination signal to the LED  23 , in response to the reception of the sub-apparatus control signal, and illuminates it, and accordingly indicates the call signal arrival (Step S 5 ).  
         [0041]    A display panel surface of the sub-apparatus  20  has, for example, a call signal arrival display  31  constituted by the LED  23  and a button  32  of a response switch  25 , as shown in FIG. 3A. The light emission of the LED  23  causes the call signal arrival display  31  to be illuminated, and thereby causes the call signal arrival to be indicated. Thus, the user responses by pushing down the button  32  (the response switch  25 ). Hence, a response signal is wirelessly transmitted through the controller  22  and the easy radio device  21  to the portable telephone body  10  by using the weak electric wave (Step S 6 ).  
         [0042]    When the easy radio device  13  in the portable telephone body  10  receives the response signal and sends to the controller  12  (Step S 7 ), the controller  22  instructs the transmitter/receiver  11  to wirelessly transmit one preliminarily prepared message (for example, [Now, I Can Not Answer Telephone]) (Step S 8 ). After that, the controller  22  automatically carries out a disconnection process, and the communication is ended (Step S 10 ). Thus, according to this embodiment, the response to the call signal arrival can be done without any trouble to a stranger, even in a case of a call signal arrival at a position where a call arrival tone gives a trouble to an adjacent stranger, during a meeting, during taking a train or the like.  
         [0043]    Also, the sub-apparatus  20  is designed so as to enable the radio communication with the portable telephone body  10  by using the weak electric wave. It is another apparatus mechanically separated from the portable telephone body  10 , and the call signal arrival is displayed while it is illuminated. So, the user need not always carry it on the body, such as the vibrator. The user can be released from the inconvenience that the user always carries it on the body.  
         [0044]    When the sub-apparatus operation switch is set off, a call arrival tone is ringed in the portable telephone body  10 , similarly to the conventional technique, and a call to the caller is done through a procedure similar to that of the conventional technique (Step S 9 ). A disconnecting operation is done in accordance with the end of the call, and the communication is ended (Step S 10 ).  
         [0045]    By the way, the number of response messages is only one in the configuration of the display panel surface of the sub-apparatus  20  shown in FIG. 3A. However, a plurality of response messages are prepared in the controller  12 , in a case of the configuration of the display panel surface shown in FIG. 3B. In FIG. 3B, the same symbols are given to the same configuration parts as those of FIG. 3A, and their explanations are omitted. In FIG. 3B, a transmission source indicator  33  and a message indicator  34  are respectively constituted by the LCDs  24  of FIG. 1. Also, a message selection switch  35  is not shown in FIG. 1. However, it is mounted in the sub-apparatus  20 .  
         [0046]    A transmission source information received together with the call arrival signal from a radio basic station in the portable telephone body  10  is transmitted from the portable telephone body  10  to the sub-apparatus  20  by using the weak electric wave, and it is displayed in the transmission source indicator  33 . Also, the message indicator  34  is designed so as to selectively indicate a plurality of preliminarily prepared messages or the identifiers of them and also indicate one message arbitrarily selected by the user using the message selection switch  35 .  
         [0047]    In this case, the plurality of preliminarily prepared messages includes the following contents. That is to say, the content that now, the user can not answer telephone and the content that now, the user is in a meeting, and so the user will call the partner later and the content that the user is in a car or train, and so the user will call the partner later and the content that the user call the partner an hour later and the content that the user will call the partner two hour later and the content that the user will call the partner three hour later and the content that the user will call the partner without any delay from another place are included.  
         [0048]    When the sub-apparatus  20  has the display panel surface in FIG. 3B, if the user responds to the call signal arrival by pushing down the button  32  (response switch  25 ), the message selection signal together with the response signal is wirelessly transmitted through the controller  22  and the easy radio device  21  to the portable telephone body  10  by using the weak electric wave, and it is received by the easy radio device  13  in the portable telephone body  10 , and sent to the controller  12 . Then, the controller  12  instructs the transmitter/receiver  11  to wirelessly transmit one message selected in accordance with the message selection signal from a plurality of preliminarily prepared messages.  
         [0049]    Thus, when the sub-apparatus  20  has the display panel surface in FIG. 3B, even if there is a call signal arrival at a position where a call arrival tone gives a trouble to an adjacent stranger, a response to the call signal arrival can be naturally carried out without any trouble to the stranger. Moreover, it is possible to transmit a message optimal for a current situation of the user. Thus, a further appropriate response to the call signal arrival can be provided for the transmission source.  
         [0050]    By the way, the present invention is not limited to the above-mentioned embodiment. For example, the call signal arrival may be reported by a flashing indication. It is not always necessary that the sub-apparatus  20  is the desk top type or the card type. It may be designed that the user carries the sub-apparatus  20  on the body, as necessary, during taking a bus or a train. Moreover, the above-mentioned embodiment is applied to the portable telephone. However, the present invention may be similarly applied to a data communication apparatus and the like.  
         [0051]    The present invention is accomplished in view of a two-way communication type of easy radio technique represented by Bluetooth or the PIAFS (PHS Internet Access Forum Standard) or like. It is designed such that a sub-apparatus can wirelessly communicate with a portable radio communication apparatus body by using a weak electric wave, and is another apparatus mechanically separated from the portable radio communication apparatus body, and a call signal arrival is displayed on the sub-apparatus. Thus, a user need not always carry it on the body, such as a vibrator. Also, the call signal arrival can be reported by using a method besides a call arrival tone and a vibration. A response to the call signal arrival can be attained by sending a response message in accordance with a response signal.  
         [0052]    In the present invention, the sub-apparatus can be driven by using an operation switch only at a necessary time, and the portable radio communication apparatus body can be used in the same manner as the conventional technique.  
         [0053]    In the present invention, a user can select one response message from a plurality of response messages, depending on the situation of the user.  
         [0054]    As mentioned above, according to the present invention, the call signal arrival is indicated by using the sub-apparatus that is another apparatus mechanically separated from the portable radio communication apparatus body. So, the user need not always carry it on the body, such as the vibrator. Thus, the user can be released from the inconvenience that the user always carries it on the body. Also, according to the present invention, the call signal arrival can be reported by using the method besides the call arrival tone and the vibration. In the response to the call signal arrival, the response message is automatically sent on the basis of the response signal. Hence, the response to the call signal arrival can be done without any trouble to the adjacent strangers.  
         [0055]    Also, according to the present invention, one response message arbitrarily selected by using the message selection switch is transmitted to the destination terminal. Thus, one response message can be selected from the plurality of response messages, depending on the situation of the user. Hence, the further appropriate response to the call signal arrival can be provided for the transmission source.
