It is determined whether it is an AX reception notification (facsimile reception information), that is, a reception notification from the facsimile machine 20, and if this is "N", other data reception processing is performed. If step 1) is "Y" in 8, that is, if it is FAX reception notification information, the content of the FAX reception notification information is further analyzed in step 120, and dial data (caller dial information). And if this is "Y", step 1
At step 21, a search is made to determine whether or not the same dial number as the received dial data exists in the telephone directory stored in the RAM 16 of the main device 1. This telephone directory consists of multiple dial numbers and corresponding multiple addresses (attribute information). And step 121
If the answer is "Y", that is, if there is the same corresponding dial number in the telephone directory, then in step 122, the display pattern C, that is, the display data "rFAX" (information indicating the receiving status of the facsimile machine 20) and the dial number are displayed. Create the address display data corresponding to the number and press "N"
In this case, if the same number does not exist, in step 124 display pattern B, ie, display data "rFAX" and display data of the received dial number, are created, and the process moves to step 125. If, in step 120, there is no dial data in the fax reception notification, only the display data ``NJ'', ie, ``rFAX dial'' is created in step 123, and the process proceeds to step 125. Step 12
In step 5, one of the above display patterns is displayed on the LCD in the display circuit 36 of a specific handset 4, in step 126 this handset 4 is caused to send out a reception sound, and in step 127 a display timer is started. Then, in step 128, a timeout of this display timer is detected, and if this is "Y", that is, if it is detected, then in step 129, this
The display circuit 36 is controlled to display a calendar on the LCD. In this manner, when the facsimile device 20 starts facsimile communication, the facsimile device 20 searches for incoming facsimile information and transmits FAX reception notification information, that is, facsimile reception information to the main device l. Then, the main device 1 receives this FAX reception notification information, performs this detection, creates display data according to the detection result and sends it to a specific slave device 4, and uses this display data to display This is displayed on the circuit 36. [Effects of the Invention] As is clear from the above explanation, the button telephone device according to the present invention is configured to detect facsimile reception information and display information indicating the reception status of the facsimile device on a specific button telephone. This has the effect of making it possible to identify the operating status of a facsimile machine from a specific key telephone. In addition, when caller dial information is detected from facsimile reception information, this caller dial information and information indicating the above reception status are displayed on a specific key telephone, so that calls to the facsimile machine are This has the effect that the caller's dialed number can be identified. Furthermore, in a key telephone device equipped with a telephone directory function, attribute information is searched from the caller dial information, and depending on the search results, either the caller dial information or the attribute information is assigned to a specific key telephone device. Since the above-mentioned information indicating the reception status is displayed, it is possible to identify the caller to the facsimile machine.
