Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone device for selectively displaying, on a key telephone, provided information obtained by receiving radio waves by a radio selective calling method at a main unit.

[0002]

2. Description of the Related Art In a conventional button telephone, a display section using an LCD (liquid crystal display) is provided in addition to a handset, dial buttons and function selection buttons. The display unit displays the date, the day of the week, the time, etc. before the call, and when the dial button for starting the call is operated, the dialed digits are displayed, and at the same time, the call time and the like are also displayed.
In addition, a display corresponding to the pressed content of the function selection button is performed. Such a key telephone makes an outside line call through the main unit and also performs various telephone services, for example, I
SDN also provides a notification service such as the telephone number of the calling device.

By the way, in recent public line networks, an information providing service by radio selective calling employing a cellular system is provided or expected. For example, as this kind of information providing service, there is a notification service of information such as stock price, gold market price, news, and specific weather forecast for a specific user, and this notification service specifies a specific call number (ID code). The selected selective call portable device is wirelessly transmitted and notified.

[0004]

As described above, in the above-mentioned conventional button telephone device, the display before the call and the dialed digits at the time of the call are displayed. That is, the wireless selective call information cannot be displayed.

As a proposal related to such a key telephone and a selective calling device, Japanese Patent Laid-Open No. 59-141839.
"Paging reception system" disclosed in Japanese Patent Laid-Open Publication No. Sho-6
The "paging system" disclosed in JP-A-3-050128 and the "pocket pager display control device" disclosed in JP-A-63-258124 can be mentioned.

An example of Japanese Patent Laid-Open No. 59-141839 is
A pager information reproducing means is added to the pager receiving device. That is, the work of making a phone call to confirm pager information is unnecessary. JP-A-63-05012
In the example of Publication No. 8, the display information retrieved by the character / graphic information network system is transmitted to the receiver of the paging system and displayed. Therefore, the display information sent by the character / graphic information network system can be easily confirmed even when out of the office. In the example of Japanese Patent Application Laid-Open No. 63-258124, only the error detection portion of the information data in the pocket pager is displayed in blinking, and at the same time the normally received information data is displayed in a lit state. This improves usability.

[0007] In each of the examples of this publication, it is not possible to display information relating to selective calling on the key telephone.

The present invention has been made in view of the above-mentioned circumstances, and the information provided by the wireless selective calling method obtained by the main unit can be displayed on the button telephone at any time, and its convenience is improved. The purpose is to provide a telephone device.

In the main device, a radio receiving means for receiving and processing a radio wave containing provision information and transmitting the provision information, a storage means for storing the provision information, and a transmission request for the provision information stored in the storage means from the key telephone. In response to the request, the provision information stored in the storage means is provided to the key telephone that has made the transmission request.

Further, the radio wave including the provided information is configured to adopt the radio selective calling method.

In addition to the configuration in this case, a wireless selective call recognition means for recognizing the identification number of the device by receiving radio waves by the wireless selective call method is provided, and the wireless selective call recognition means identifies the device. Only when the number is recognized, the radio wave received by the wireless receiving means is processed and the provided information is transmitted.

Furthermore, when the identification information indicating that the provided information from the wireless receiving means is new information is confirmed,
The storage means is provided with an information confirmation means for transmitting new provision information, and the storage means rewrites the information.

The present invention also includes a plurality of key telephones,
In a key telephone device including a main device for controlling a plurality of key telephones to make a call and make a call, each of the plurality of key telephones instructs a request for sending the additional information stored in the main device and a stop of display of the additional information. Instruction means for displaying the provision information, display means for displaying the provision information, and a transmission request signal for the provision information stored in the main device based on the instruction of the instruction means to be displayed on the display means, and the provision provided. And a display control unit that controls the display stop by identifying the instruction to stop the display of the information.

[0014]

The button telephone device of the present invention having the above-mentioned configuration stores the latest provided information obtained by receiving and processing radio waves,
The stored provided information is sent by an instruction from the key telephone. The latest provided information is displayed on the display unit of the key telephone that requested the transmission. Therefore, the information provided by the wireless selective calling method obtained by the main device is displayed on the key telephone at a desired time.
