[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cordless system telephone device, and more particularly to a control device connected to a public line, a plurality of master devices connected to the control device, and any one of the plurality of master devices. The present invention relates to a cordless system telephone device comprising a plurality of cordless handsets for communicating voice information by a radio signal, which cordless system telephone device can display the cordless handset number of the cordless handset so that the user can visually confirm it.

[0002]

2. Description of the Related Art Conventionally, a plurality of slave units and at least one slave unit have been used.
There is a cordless system telephone device that wirelessly communicates a voice signal by selectively using a plurality of wireless channels with one base unit. Such a cordless system telephone device
When there are one or more master devices, a control device that controls the connection to the fixed telephone network requested by the slave device through the master devices, and one or more master devices connected to this control device. And a plurality of slave units that wirelessly communicate with these master units. Further, in a cordless system telephone device having only one master unit, it is usual that one master unit also serves the function of the control device. When such a cordless system telephone device receives an incoming call from the fixed telephone network, it simultaneously calls all of the plurality of slave units. On the other hand, the cordless handset user can respond to any of the plurality of cordless handsets that have called all at once, and only the cordless handset that responds first can give priority to the incoming call. Yes, so-called preemptive priority response is possible. Therefore, if any one of the slaves responds first to the simultaneous slave call, the other slaves cannot respond to the incoming call. Further, there is a so-called PAGE function of calling another child device via the parent device from the child device that responded to the incoming call and transferring the incoming call. Further, in the case of making a call, it is possible to make a call from any of the slaves and to make a call from a plurality of slaves as many as the number of telephone lines connected to the master.

By the way, when calling another slave unit via the master unit by the PAGE function or the like, the slave unit number corresponding to each slave unit is used to dial the slave unit on the calling side. However, this cordless handset number is the R and R of the cordless handset and the cordless handset when registering the cordless handset to the cordless handset when the system is set up or manufactured or when a new cordless handset is used.
It is stored in the OM or the like together with the ID (Identification) number of the slave unit.

[0004]

The cordless handset number of such a conventional cordless system telephone is stored in the ROM of the cordless handset and the cordless handset when the cordless handset is newly registered in the cordless handset as described above. Although the slave unit number is stored, only the storing operation can be performed, and a confirmation unit for registering the slave unit number has not existed in the past. Therefore, make sure that the slave unit number is correctly stored so that there are no errors such as duplicate registration of the slave unit number, and that the slave unit number is correctly assigned to the target slave unit. There is a problem that you cannot do it. In addition, although some child devices are equipped with a liquid crystal display that displays dial operation status, etc., since the child device itself does not have a means for displaying the child device number, the child device number cannot be displayed. The correspondence between the machine and the child machine number may be unclear depending on the usage situation. In other words, when compared to a conventional immovable telephone connected to a private branch exchange connected by wire, the cordless handset itself moves freely, and there is a risk that the cordless handset number may be lost due to the confusion between cordless handsets. is there. In order to prevent such a slave unit number from becoming unclear, conventionally, at the time of system setting or at the system manufacturing stage, the manufacturer attaches a piece of paper on which the slave unit number is written to the outer surface of the slave unit. Is going. Also, when multiple slave units are newly registered in the master unit, to confirm the master unit registration of this slave unit number, confirm the slave unit number by an unnecessary wireless connection test unrelated to the call. There is. further,
When the child machine user loses the child machine number entry sheet as described above or forgets the child machine number, he / she has to register again the child machine whose lost child machine number is unknown to the parent machine. Furthermore, since a plurality of slave units are used, it has been conventionally problematic that it is not possible to easily confirm who is using which slave unit.

Therefore, an object of the present invention is to eliminate such problems of the related art and to display and confirm the slave unit number of the slave unit by a simpler work, and to cope with the slave unit number and slave unit user correspondence. It is to provide a cordless system telephone device that can easily identify a telephone.
