Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button telephone device, and when the operator of a plurality of button telephones leaves his/her seat, the operator of the destination display device can dial an access code for a predetermined destination. At the same time as the destination is displayed on the telephone, when a call is received to a telephone where the operator is not present, the destination display device converts the destination of the operator from the data in the display memory into a voice signal and responds to the call. The present invention relates to a button telephone device.

Conventionally, this type of button telephone device does not have a function to display the destination of the operator of each button telephone, and incoming calls to a telephone where the operator is not available are answered by someone other than the operator. Either they would reply that they were absent, or they would install an answering machine for each central office line/PBX line and reply that they were absent.

Therefore, the destination of each telephone operator must be displayed on a blackboard, etc. each time he or she leaves his/her seat, and another person must always answer an incoming call from an absent telephone operator. However, there were disadvantages such as temporary interruption of work.

The present invention is equipped with a destination display device, an audio signal conversion circuit, etc., so that when the operator of multiple telephones leaves his or her desk, a code, such as "11", inputted in advance into the display memory from the keyboard device is displayed as a conference call. In the middle, "12" is for going out, etc. By dialing the user's arbitrary access code, the destination such as KAIGI (meeting), GAISHUTSU (outing), etc. will be displayed at the operator's position on the destination display device. At the same time, in response to an incoming call to a telephone where the handler is not present, the destination of the handler is converted from the data in the display memory to a voice signal, and the caller's destination is converted into a voice signal saying, ``I'm currently in a meeting.'' or ``I'm out of the office.'' By returning a message such as ``.'', you can save yourself the trouble of writing on a display field on a blackboard or other display every time you leave your desk, and you can also avoid the need for other people to answer incoming calls to your phone while you are away. This provides a device that allows users to concentrate on their work without any temporary interruptions.

To explain the configuration of the present invention, the present invention has the following features:
In a button telephone device consisting of a main device and a large number of button telephones connected to the main device, a display device that stores destination codes input from each button telephone and destination display data corresponding to the destination codes on the main device side. a memory circuit; a display circuit for reading destination display data corresponding to a destination code for each button telephone from the display memory circuit and displaying it on the destination display device; determines whether or not the call is stored in the memory circuit for the call, and if it is not stored, controls the connection of the call path so as to form a call path between the calling side and the called side button telephones;
If stored, the destination code read from the display memory circuit is converted into a voice message by a voice signal conversion circuit, and the control circuit controls the voice message to be sent to the calling party.

The present invention will be explained below by way of examples with reference to the drawings.

FIG. 1 shows a block circuit diagram of a button telephone device with destination display according to an embodiment of the present invention.

As will be explained with reference to FIG. 1, it is necessary to set the destination code of the operator of each telephone as an initial setting of this system. The user inputs an arbitrary destination code from the keyboard device 90. For example, if you want destination code 10 to be in a meeting, use ``CODE 10 SI KAIGICHU'', and if you want destination code 20 to be ``outing'', use ``CODE 20 SI''.
GAISHUTSU”, “10” is input to the code memory location of the display memory circuit 70 via the display interface circuit 60.
or "20", and "KAIGICHU" or "GAISHUTSU" are stored in the data memory location corresponding to this code memory location.

Next, when the operator of each telephone 100 leaves his/her seat, he/she lifts the handset and dials "10", and the display memory circuit passes through the telephone interface circuit 40, the communication path connection circuit 20, and the communication path control circuit 30. 70
"10" is stored in the memory location corresponding to each telephone 100, and at the same time, "KAIGICHU" or “GAISHUTSU” is displayed.

Next time you receive an incoming call from the central office line/PBX line,
The central office line/PBX line interface circuit 10 detects an incoming call, the call path control circuit 30 accesses the data memory location of the display memory circuit 70 to see if the operator of the telephone that received the call is away, If the content of the data memory is 0, a call loop is established in the call path connection circuit 20, a ring tone is sounded on the incoming telephone in the telephone interface circuit 40, and the central office line/PBX is activated by raising the handset of the telephone. You can talk to the line.

If the content of the data memory in the display memory circuit 70 is 10, the audio signal conversion circuit 80 converts the content 10 of the data memory into an audio signal, and sends the message "Currently in a meeting" to the telephone interface circuit. 40, communication path connection circuit 20, office line/
It is sent back to the office line/PBX line via the PBX line interface circuit 10.

Then, for an incoming call from a phone in the system,
The telephone interface circuit 40 detects an incoming call, accesses the data memory of the display memory circuit 70 via the communication path connection circuit 20 and the communication path control circuit 30, and if the content of the data memory is 0,
A call loop is established in the call path connection circuit 20, a ring tone is sounded on the incoming telephone in the telephone interface circuit 40, and the handset of the telephone is raised, thereby allowing communication between telephones in the system.

If the content of the data memory in the display memory circuit 70 is 10, the audio signal conversion circuit 80 converts the content 10 of the data memory into an audio signal, and sends the message "Currently in a meeting" to the telephone interface circuit. 40 to the telephone in the system that made the call.

As explained above, according to the present invention, when the operator of a telephone in the system dials a predetermined access code, the destination is displayed at the position corresponding to the telephone on the destination display device, and When an incoming call is made to a telephone that is absent, a message can be sent back to the calling party to inform that the person is absent.This saves the trouble of writing the destination on a blackboard, etc., and at the same time, the automatic answering service saves other people's work. This has the effect of allowing other people to concentrate on their work without interruption.
