Abstract

PURPOSE:To improve the operability by selecting a function through the changeover of display without increasing number of operation buttons for the service of plural functions in the multi-function telephone set. CONSTITUTION:This telephone set consists of a key matrix section 3, a liquid crystal display device 4 implementing state display and a changeover button 5 switching the function of a button. The display of the liquid crystal display device 4 is revised by depressing the function changeover button 5 to change the function display and the state display of the operation button of the key matrix section 3. Thus, since lots of functions are used by less number of buttons, the external size of the multi-function telephone set is decreased. Furthermore, since the display is switched corresponding to the operation button, the operability is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a multifunction telephone,
In particular, the present invention relates to a multi-function telephone for using operation buttons for multiple functions.

[0002]

2. Description of the Related Art Conventionally, in a multi-function telephone of this kind, a function for each operation button is fixedly determined, or even when a plurality of functions are assigned, the function is not displayed because the operator does not display the function. Was memorized, or more than one was displayed and used properly.

[0003]

However, in the above-mentioned conventional multi-function telephone, as the number of functions increases as the system becomes more sophisticated, more operation buttons are required, and thus the multi-function telephone is required. However, if one button has a plurality of functions without increasing the number of operation buttons, there is a drawback that the operability is poor because there is no display corresponding to the selected function.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, an object of the present invention is to provide a novel multifunction telephone capable of solving the above-mentioned drawbacks inherent in the conventional technology. Especially.

[0005]

In order to achieve the above object, a multi-function telephone according to the present invention comprises a communication interface section for transmitting and receiving control information and a voice signal which are prearranged with a private branch exchange. A microprocessor unit for controlling an internal circuit of the multi-function telephone, a key matrix unit which is detected by the microprocessor unit, a liquid crystal display for displaying a function display and a usage state of each operation button, It is configured to include a display button of the liquid crystal display and a switching button for arbitrarily switching the function corresponding to the button.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings with reference to the accompanying drawings.

FIG. 1 is a functional block configuration diagram showing an embodiment of the present invention.

2A and 2B show the operation panel surface and display contents of one embodiment of the multifunction telephone according to the present invention.

Referring to FIG. 1, an embodiment of a multi-function telephone according to the present invention includes a communication interface section 1 for transmitting and receiving control information and voice signals which are prearranged with a private branch exchange side. A microprocessor 2 for controlling an internal circuit of the multi-function telephone, and a key matrix unit 3 of a local line button which is detected by the microprocessor 2
And a liquid crystal display 4 for displaying correspondence between each station line button and the use state of the station line and a switching button 5 for switching a function for each station line button.

In this embodiment, four station line buttons are mounted, and a case where eight station line buttons are used will be described.

First, when the multi-function telephone is connected to the private branch exchange, the microprocessor 2 receives four local line buttons from the local lines # 1 to # according to the button control information from the private branch exchange.
4, and the number corresponding to each button is displayed on the liquid crystal display 4.

Next, control information indicating the usage status of eight office lines from the private branch exchange is stored by the microprocessor 2 via the interface section 1.

As a result, the microprocessor 2 sends the control lines # 1 to # to the liquid crystal display 4 among the received control information.
Display status 4.

In this state, the operator can confirm the usage status of the station lines # 1 to # 4, and the four station line buttons are station line numbers # 1 to #.
When the local line button is pressed at this time, the microprocessor 2 detects the pressing by the signal from the key matrix section 3, and the key data corresponding to the button is sent via the communication interface section 1 to the private branch exchange device. Send to the side.

FIG. 2A shows the operation panel surface of the multifunction telephone at this time.

Next, when the operator presses the function switching button 5, the microprocessor 2 detects the pressing signal from the key matrix 3, and the liquid crystal display is made by the button control information previously received from the private branch exchange. The display of the container 4 is switched as shown in FIG.

Now, the four station line buttons are station lines # 5 to #.
It can be used as a button corresponding to 8,
It is possible to use the station lines # 5 to # 8 by the same operation as that of the station lines # 1 to # 4.

In this state, the operator receives the station lines # 5 to # 8.
You can check the usage status of each station and the four station line buttons are the station line number #
5 to # 8, and when the local line button is pressed at this time, the microprocessor 2 detects the pressing by the signal from the key matrix section 3 and outputs the key data as # 5 to # 8 corresponding to the button. It is transmitted to the private branch exchange side via the communication interface unit 1.

[0019]

As described above, according to the present invention,
Since it can be used for many functions with a small number of buttons, the external dimensions of the multi-function telephone can be reduced.

Further, by providing a liquid crystal display and displaying the selected function in correspondence with the button, the effect of improving the operability as compared with the conventional model can be obtained.
