Abstract

PURPOSE:To enable an user to recognize the operating state of a facsimile equipment on a display section without visit to the facsimile equipment by monitoring a signal of an extension terminal exclusive for the facsimile equipment so as to display the communication state onto a display section of a key telephone terminal. CONSTITUTION:Upon the receipt of a detection signal of a MODEM 6, a FAX monitor control section 7 monitors in which state a FAX 1 resides depending on the content of the signal to detect a number of a communication opposite party. The FAX monitor control section 7 sends information of the communication state to a main control section 9 when the communication state of the FAX 1 changes. Moreover, when an opposite telephone number is detected, telephone number information is sent to the main control section 9. The main control section 9 sends the information to other key telephone terminal 2. Upon the receipt of the information of the communication state from the main control section 9, each key telephone terminal 2 displays the communication state of the FAX 1 onto each liquid crystal display device according to the content. When the telephone number information of the opposite party is received, the number is stored and displayed as required by the operation of the user.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to key telephone equipment.

[Conventional technology]

In order to use central office lines efficiently, conventional key telephone devices have a dedicated terminal for connecting a facsimile device in addition to an extension terminal for connecting the key telephone terminal, allowing the key telephone terminal and facsimile device to operate independently. It was configured to be usable.

[Problem to be solved by the invention]

The conventional key telephone device described above is configured so that the key telephone terminal and facsimile device can be used independently, so even if the facsimile device receives an incoming call or is in use, The disadvantage is that you cannot tell until you go to the equipment.

[Means to solve the problem]

The key telephone device of the present invention is a key telephone device including a main device accommodating a plurality of key telephone terminals having a display function and a plurality of office lines, wherein the main device has a connecting means for connecting a facsimile device, and a connecting means for connecting a facsimile device; detecting means for detecting from the means that the facsimile machine is in use; and when the detecting means detects that the facsimile machine is in use, the key telephone terminal is notified that the facsimile machine is in use; and display control means for displaying.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

In FIG. 1, the key telephone device of this embodiment includes a facsimile machine (hereinafter referred to as FAX) 1, a plurality of key telephone terminals 2 equipped with liquid crystal displays, and a plurality of central office lines 1.
2 via terminals 4.5, 10° 11
The main device 3 includes a FAX 1, a plurality of key telephone terminals 2, an exchange switch section 4 including an interface section for a plurality of key telephone terminals 2, and a switch section for connecting these;
A modem 6 that detects a FAXI communication signal from a connection terminal 4, a facsimile machine (FAX) monitoring control unit 7 that monitors the communication status of the FAXI based on the detection signal of the modem 6, and a status of the FAXI from the FAX monitoring and control unit 7. The main control section 9 displays the communication status of the FAX 1 on a liquid crystal display (not shown) of the key telephone terminal 2 via the exchange switch section 8 upon receiving a change signal.

Next, the operation of the facsimile machine of this embodiment in use will be described.

When FAXI starts communication through the FAX-dedicated office line 10, the receive-only modem 6 starts detecting a signal on the FAX connection terminal 4. When the FAX monitoring control unit 7 receives the detection signal from the modem 6, the FAX monitoring control unit 7
monitor its condition. It also detects the number of the communication partner included in the signal. When the FAXI communication status changes, the FAX monitoring control unit 7 sends communication status information to the main control unit 9. Further, when the other party's telephone number is detected, the telephone number information is sent to the main control section 9.

Next, the main control unit 9 transmits this information to other key telephone terminals 2. When each key telephone terminal 2 receives communication status information from the main control unit 9, it
The FAXI communication status is displayed on each LCD display. Also, if you receive the other party's phone number information,
The number is memorized and displayed as required by the user's operation.

〔Effect of the invention〕

As explained above, the present invention has the display control means in the main device that monitors the signal of the extension terminal dedicated to the facsimile machine and causes the communication status of the facsimile machine to be displayed on the display section of the key telephone terminal. This has the effect that the usage status of the facsimile machine can be known on the display section of the user's key telephone terminal without having to go to the facsimile machine.
