JPS62185439A - Key telephone set with voice incoming call guide - Google Patents

Abstract

PURPOSE:To easily identify a incoming trunk line even for a visually handicapped person by displaying an incoming call from a trunk line by a trunk line display lamp and a voice synthesis sound so as to identify the incoming trunk line. CONSTITUTION:A master equipment 2 sends an incoming data formed by coding the incoming information of a trunk line to a data transmission line 22 and keeps sending the said incoming data until one of key telephone sets acquires a line. The control circuit 12 of a key telephone set 1 inputs an incoming data and drives LEDs 13a-13d corresponding to the incoming trunk line of a trunk line display lamp group 13. Further, a voice data recorded in the control circuit 12 is outputted to a voice synthesis circuit 14, where a sound signal is synthesized. Different voice data from trunk lines are stored in advance in the control circuit 12 and the voice data corresponding to the incoming data is outputted from the control circuit 12 at every time the incoming data is inputted.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a key telephone equipped with a central office line indicator lamp as a means for displaying the central office line on which a call is being received.

(Prior Art) Conventionally, in a key telephone connected to a main device accommodating a plurality of central office lines, when a call is received from the central office line, for example, the LE
Using a station line indicator lamp composed of a light emitter like D,
It displayed the central office line where the call was received.

(Problem to be Solved by the Invention) In a conventional key telephone that determines the incoming station line only by visually checking the station line indicator lamp, if a large number of answerable station lines are accommodated, it is difficult to receive calls from the station line. Even if a call is received, it is difficult to immediately judge which telephone line the call is received on, and there are problems with operability, especially for people who are visually impaired, as they cannot judge at all which telephone line to respond to. there were.

SUMMARY OF THE INVENTION An object of the present invention is to provide a key telephone with excellent operability and which allows even visually impaired people to determine the calling station line.

(Means for resolving the problem at once) In order to solve the problems mentioned above, the present invention provides a means that is connected to a main device accommodating a plurality of central office lines by a data transmission line, When an incoming call is received from the main device, the main device detects the incoming call and receives the incoming call information from the main device via the data transmission line, and when the incoming data is received, it drives a central point indicator lamp. A button telephone that displays the central office line on which an incoming call has been received; the button telephone has a circuit that stores in advance specific voice data corresponding to each of the central office lines; It is characterized by comprising a circuit for selecting the audio data, a speech synthesis circuit for synthesizing an audio signal by inputting the audio data selected by the selection circuit, and a sounding body for converting the audio signal into an audible sound. do.

(Example) Embodiments of the present invention will be briefly described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. This embodiment detects the terminal 11 connected to the data transmission line 22 and the data sent from the main device 2, and
A control circuit 12 that drives the amplifier 13 and outputs specific audio data recorded in advance, and LEDs 13a to L3.
A station line indicator lamp group 13 consisting of a, and a voice synthesis circuit 14
and a sounding body 15 that converts the output signal of the speech synthesis circuit 14 into an audible sound.

Now, when there is an incoming call on the central office line, the main device 2 sends the incoming call data encoded with the incoming call information on the central office line to the data transmission line 22, and from then on, the incoming call data is transmitted until one of the key telephones captures the line. continue to send out.

The control circuit 12 of the button telephone 1 inputs the incoming call data and drives the tED13a to L3d corresponding to the receiving office line of the office line indicator lamp group 13, while the voice synthesis circuit 1
4, outputs the audio data recorded in the control circuit 12, and causes the audio synthesis circuit 14 to synthesize the audio signal. The control circuit 12 stores in advance voice data different from each other for each office line, and each time incoming call data is input, the control circuit 12 outputs voice data corresponding to the incoming call data. LED L configuring station line indicator lamp group 13
3a to 13d are central office lines and 1 accommodated in the button telephone 1.
It corresponds to one-to-one communication, and an incoming call from the corresponding central office line is indicated by blinking the LIiSD. The sounding body 15 is an electroacoustic transducer that converts the audio signal output by the speech synthesis circuit 14 into an audible sound.

Note that the voice synthesized sounds outputted from the sounding unit 15 are, for example, "Kfi call number 1." or "It's call number 3." and are sounds that identify the incoming station line.

(Effects of the Invention) As described above, in the button telephone according to the present invention, by displaying an incoming call from a central office line together with a central office line indicator lamp and a voice synthesized sound, it is easy to identify the incoming central office line, and operability is improved. This has the effect that even visually impaired people can easily identify the receiving station line.
