CONSTITUTION:When a key telephone set 11 is in extension talking with a key telephone set 1 and the key telephone set 1 is busy, a control section 26 retrieves a message number by the operation of a specific button. For example, when a message number No.1 is retrieved, message information is called from a message information storage section 27 to index the character information. Then the retrieved information such as 'You are wanted on another phone' is sent to a display section 12 of the busy key telephone set 1 via a display information transmission section 24. When the opposite party is discriminated to be not busy, the extension talking between the key telephone sets 1, 11 is attained. Thus, the message is informed to the opposite party only as required at all times even during talking.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a button telephone device comprising a main device for controlling connections and a plurality of key telephones each having a display section for displaying display information received from the main device in text. Regarding.

[Conventional technology]

Conventionally, this type of key telephone device has been configured so that when the other party's telephone is busy, the other party is called as soon as the other party's call ends, or the other party is notified by a tone that the other party is on standby.

In such a case, waiting for the other party to finish the call would be too late, and the business would have to be handed over directly in a memo or the like, which was very inefficient.

[Means to solve the problem]

The button telephone device of the present invention includes a main device that controls connection, and a plurality of button telephones each including a display unit that displays display information received from the main device in text, in which a button corresponding to a pressed button is pressed. a message information storage section that stores in advance a pair of message information and message information corresponding to the pressed button; and a message information storage unit that stores a pair of message information corresponding to the pressed button; and when a specific button is pressed during a call, the pressed button information corresponds to the pressed button and the message information corresponds to the pressed button. The message information retrieval means searches and reads message information from the message information storage section, and the control means transmits the read message information as display information to the key telephone.

〔Example〕

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

FIG. 1 is a schematic diagram showing one embodiment of the present invention, and FIG. 2 is a flowchart showing an example of the main operating procedure of this embodiment.

In FIG. 1, in this embodiment, a plurality of key telephones 1 and 11 are housed and connected to a main unit 2 along with a plurality of office lines 3. The button telephones 1 and 11 have liquid crystal character display sections 12 and 13, and receive and display display information under the control of the main device 2.

The main device 2 includes a button telephone interface 21, a trunk circuit 22, a communication path 23, a display information transmitter 24,
It includes a search section 25, a control section 26, and a storage section 27.

The trunk circuit 22 accommodates a plurality of office lines 3, detects incoming signals from the office lines 3, and sends dial signals to the office lines 3. Signals from the key telephones 1, 11 and the central office line 3 are coupled to a speech path 23 via a trunk circuit 22 and a key telephone interface 21. The button telephone interface 21 accommodates a plurality of button telephones, and sends button information and hook switch information from the button telephones to the control unit 26 via the data input/output circuit 24. The search unit 25 detects data matching the information sent from the control unit 26 from the message information storage unit 27. The display information transmitter 24 transmits display information to be displayed on the display sections 12, 13 of the button telephones 1, 11 via the button telephone interface using a predetermined signaling method. Message information storage section 27
stores in advance a pair of button information and message information corresponding thereto.

Next, the operation of this embodiment will be explained using FIG. 1 and FIG. 2 together.

When the key telephone 11 makes an extension call to the key telephone 1 (Sl) and it is determined that the key telephone 1 is busy (S3), the control unit 26 searches for a message number by operating a specific button (S3). (S4). For example, here is the message number NO.

1, the message information is retrieved from the message information storage section 27 (S5), the character information is indexed (S6), and this index information "Denwaga Hittemas°" is sent as display information via the display information transmission section 24. , is transmitted to the display unit 12 of the key telephone 1 that is currently on the call (S7).

Also, if it is determined in step S2 that the other party is not busy,
Extension calls between button telephones 1 and 11 are now possible.

〔Effect of the invention〕

As explained above, the present invention is configured so that a message is sent from the main device and displayed on the button telephone of the other party during a call, so that messages can be communicated to the other party whenever necessary even during a call.
