Abstract

PURPOSE:To automatically attain a prescribed loud-speaking call at a set time by setting the time by the time indicated by a signal to be outputted from a clock part and a switch and outputting a sound signal stored in a storing means to plural key telephone systems when the set time coincides with the time indicated by the generated signal. CONSTITUTION:A voice for executing the loud-speaking call for key telephone sets 8a-8n is previously inputted from a microphone 5, stored in a voice storing means 6, and the time when the loud-speaking call is to be executed is set by operating switches 2a-2c. A control part 3 compares the time indicated by the signal from a clock part 4 and the time indicated by a logical signal generated by the switches 2a-2c for every prescribed time and starts the voice storing means 6 when the times become coincident. The voice storing means 6 sends the stored sound signal through a switch matrix 7 to the respective key telephone sets 8a-8n. Thus, the automatic loud-speaking call can be attained from all the key telephone sets 8a-8n at the set time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a button telephone device that performs loudspeaker calling of a plurality of key telephones, and particularly relates to a button telephone device that automatically makes a predetermined loudspeaker call at a set time. It is something.

(Prior Art) In conventional button telephone devices, loudspeaker calls to all button telephones are performed as follows. That is, when an operator performs an operation for a loudspeaker call on one button telephone connected to a key telephone device, a signal indicating activation of a loudspeaker call is sent from the button telephone to the button telephone device.

The controller of the button telephone device receives this signal, connects the operated telephone to all other button telephones via a switch matrix, and sets each button telephone to receive a loudspeaker call. . Thereafter, when the operator inputs voice from one button telephone, that voice is amplified and emitted from all other button telephones.

[Problem that the invention seeks to solve]

In the above-described conventional key telephone device, when making a loudspeaker call, the operator must always perform a predetermined operation and also input voice. Therefore, for example, in a company, etc.
Even when making a loudspeaker call with the same content at a fixed time every day as a start or end broadcast, the operator must perform predetermined operations and audio input each time.

An object of the present invention is to provide a key telephone device that eliminates such inconvenience and automatically makes a predetermined loudspeaker call at a preset time.

[Means for solving problems]

The present invention provides a button telephone device that performs loudspeaker calling of a plurality of button telephones, comprising: a clock unit that outputs a signal representing the time; a storage unit that stores an audio signal; and a device that sets a predetermined time and represents the set time. a switch for generating a signal; and when the time represented by the signal outputted by the clock unit and the time represented by the signal set and generated by the switch match, the sound is stored in the storage means; The present invention is characterized by comprising a control means for outputting signals to the plurality of button telephones.

〔Example〕

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

FIG. 1 is a block diagram showing an example of a key telephone device according to the present invention. This button telephone device 1 includes a switch group 2
, a control section 3, a clock section 4, a microphone 5, an audio storage means 6, and a switch matrix 7.
and a button telephone group 8 consisting of button telephones 8a to 8n.

Switch group 2 is for setting the time when a loudspeaker call should be made, and switches 2a to 2a making up the switch group are
By turning on/off 2c, a logic signal corresponding to the set time is output to the control section 3.

Further, the clock section 4 generates a signal representing time and outputs it to the control section 3.

The audio storage means 6 stores the audio signal input from the microphone 5, and outputs the stored audio signal to the switch matrix 7 when activated by the control unit 3. switch·
The matrix 7 is controlled by the control unit 3 so that the voice storage means 6
and all button telephones 8a to 8n of button telephone group 8
Connect with.

Next, the operation will be explained. The operator of this button telephone device 1 inputs the voice for making a loudspeaker call to the button telephones 8a to 8n in advance from the microphone 5, and
Let me remember it. Also, set the time when the loudspeaker call will be made.
Set by operating switches 2a to 2c.

The control unit 3 compares the time indicated by the signal from the clock unit 4 and the time indicated by the logic signals generated by the switches 2a to 2c at regular intervals (for example, every minute), and when they match, Activate the voice storage means 6. At this time, the control section 3 also controls the switch matrix 7 to connect the voice storage means 6 and the key telephones 8a to 8n, and further sets these key telephones to receive a loudspeaker call.

When the voice storage means 6 is activated by the control unit 3, it sends the previously stored voice signal to each of the button telephones 8a to 8n through the switch matrix 7. As a result, the voice input through the microphone 5 and stored is automatically amplified from the all-button telephones 8a to 8n at the set time.

〔Effect of the invention〕

As explained above, the present invention provides a key telephone device that performs loudspeaker calling of a plurality of key telephones, which includes a clock unit that outputs a signal representing the time, a storage unit that stores an audio signal, and a device that sets a predetermined time. An audio signal stored in the storage means when the time represented by the signal outputted by the switch for generating the signal representing the set time and the time represented by the signal set by the switch and the time represented by the signal set and generated by the switch. control means for outputting to a plurality of button telephones.

Therefore, according to the present invention, it is possible to realize a key telephone device that automatically makes a predetermined loudspeaker call at a preset time.
