Abstract

PURPOSE:To attain loudspeaker talking without pushbutton operation for reply by sending a control signal from a master set in calling simultaneously plural key telephone sets in voice so as to bring the plural called key telephone sets into the loudspeaker talking state automatically. CONSTITUTION:The button operation for predetermined simultaneous call is applied from a key telephone set 21 and a command signal for simultaneous call is sent to a master set 1 via control line 6. In receiving the command signal, the control circuit 5 decodes the signal to be a command signal for simultaneous call and sends the simultaneous call to key telephone sets 22-2r via the control line 6. Each transmission/reception switch circuit 21 of the key telephone sets 22-2r receiving the control signal is turned on and the key telephone sets 22-2r are in the loudspeaking state automatically. Thus, the key telephone sets 22-2r apply loudspeaker talking without operation of a built-in button.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a button telephone device, and more particularly to a button telephone device having a simultaneous paging function.

[Conventional technology]

Conventionally, in this type of key telephone device, multiple key telephones can be called all at once by voice from one key telephone via the main device, but each of the plural key telephones called has a predetermined number. The system is such that you cannot answer a call without pressing a button.

[Problem that the invention seeks to solve]

In the above-mentioned conventional button telephone device, - When a simultaneous call is made, each button telephone is configured so that a call cannot be answered unless a predetermined button operation is performed on each button telephone. The disadvantage is that it is time consuming.

[Means for solving problems]

The button telephone device of the present invention comprises a plurality of button telephones including a controlled circuit in which opening and closing of transmission and reception of call signals is controlled by control signals from a control line, and a main device accommodating the plurality of button telephones. In the telephone device, the main device includes a switch circuit that exchanges and connects with the plurality of button telephones via a telephone line, and a voice collection and distribution circuit that collects and distributes voices from the plurality of button telephones via the switch circuit. and a control circuit that controls the switch circuit and the voice collection/distribution circuit and transmits and receives the control signals of the plurality of button telephones via the control line, Upon reception of a simultaneous command signal from one button telephone, the control circuit sends the control signal to the remaining plurality of button telephones except for the one, and activates the controlled circuit to activate the remaining buttons. To automatically put a telephone into a loudspeaker state.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

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

In FIG. 1, the button telephone device of this embodiment is a main device 1.
and a plurality of button telephones 21+ to 2, (an integer of r≧1) connected to the main device 1 via the control line 6 and the telephone line 7.
The main device 1 is a button telephone 21.
．． A switch circuit 3 that accommodates each of the telephone lines 7 of . A voice collection/distribution circuit 4 that collects and distributes voice from 2r to 2r via a switch circuit 3, and a button telephone 21. A switch circuit 3. transmits and receives control signals of ~2r. It has a control circuit 5 for sequence controlling the entire main device 1 such as the voice collection and distribution circuit 4, and each of the button telephones 2++ to 2r transmits and receives call signals to and from the call line 7 by control signals from the control line 6. It is equipped with a transmission/reception switch circuit 21 which is opened and closed.

Next, the operation of this embodiment will be explained.

key telephone 22 from button telephone 21 . The operation in the case of a simultaneous call to ~2r will be explained.

A predetermined button (not shown) for simultaneous paging is operated from the button telephone 21, and a - general paging command signal is transmitted to the main device 1 via the control line 6.

When the control circuit 5 receives this command signal, it decodes that it is a command signal for simultaneous ringing, and calls the key telephones 22. ~2r
A control signal for simultaneous paging is sent out via the control line 6.

The transmitting/receiving switch circuit 21 of each of the button telephones 2□ and -2r that received the control signal is turned on, and the button telephones 22. ~2r automatically enters the loudspeaker mode, and the button telephone 22. ~2r are in a state where they can talk using their built-in speakers (not shown) and microphones (not shown).

Next, the control circuit 5 controls the switch circuit 3 and the voice collection/distribution circuit 4, and sends the voices received from the button telephones 21゜2□, to 2r through the telephone line 7 through the switch circuit 3. The collecting and distributing circuit 4 collects the data and sends the data to the key telephone 2□ to the key telephone 22. For the button telephone 22, the voice collected from the voices of the button telephones 21, 23, and 2r is collected.

. . . For the button telephone 2r, the voice collected from the button telephones 21+ to 2r-1 is transmitted via the switch circuit 3 to each button telephone via the telephone line 7.

In this way, each button telephone 22. -2r can make a loudspeaker call by operating the respective built-in buttons (not shown).

〔Effect of the invention〕

As explained above, in the present invention, when a plurality of key telephones are simultaneously called by voice, the main device side sends a control signal, so that the plural key telephones that are called automatically enter a loudspeaker state, so that a response can be answered. This has the effect of allowing loudspeaker calls without having to press any buttons.
