Abstract

PURPOSE:To reduce the energy consumption of a key telephone set by pushing a display switching button on the key the telephone set, and displaying the extention using condition with figures on an LCD display device on a key telephone set. CONSTITUTION:A central processing unit 2 in key telephone main equipment 1 judges whether or not a key telephone set 10 is busy by discriminating control data sent through a control data transmitting circuit 5 of the key telephone set 10, and a result is stored in a memory circuit 3. Next, when a display switching button 9 on the key telephone set 10 is pushed, a central processing unit 2 converts the using condition information of the other key telephone set 10 stored into the memory circuit 3 to the control data to display the figure or a character on an LCD display device 7 of the key telephone set 10. Further, the data are conveyed through a key telephone set interface circuit 4 to the key telephone set 10, the LCD display device 7 is driving-controlled, and the extention using condition is displayed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a button telephone device, and particularly to an extension usage status display device for a button telephone device that can display the extension usage status on an LCD display on the button telephone device. Regarding.

[Prior Art] Some conventional key telephone devices are capable of displaying the usage status of extensions using LED 79 display elements that correspond to a plurality of extension direct transfer buttons of key telephone L. Of course, some did not have the means to know how their extensions were being used.

[Problems to be solved] - The extension usage status display device of the conventional key telephone device described above is an LED that corresponds to each extension telephone of the key telephone device.
Since the usage status of extensions is displayed using , there is a drawback that the current consumption of the telephone increases. Furthermore, key telephones that do not have a means of knowing the usage status of extensions have the disadvantage that it is not possible to know whether the other party is busy until the other party's key telephone is called.

[Means for solving the problem 1 The button ``extension usage status display device δ'' of the present invention is
A central processing unit in the main body of a button telephone device capable of accommodating a plurality of button telephones, a memory circuit in which the central processing unit determines the usage status of extension f1 and stores the information, and a button telephone. has an interface circuit,
A button telephone has a control data transmission/reception circuit, an LCD display capable of displaying an extension number, and an LC that drives the LCD display.
D display circuit, a display switching button for switching the display content of the LCD display, and a button press detection circuit for detecting pressing of the display switching button, and The central processing unit reads the information stored in the memory circuit and displays the usage status of the extension on an LCD display, which consumes less power than display elements such as LEDs. The conventional problem is solved by using a display device.

[Example 1 Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The button telephone device accommodates a plurality of button telephones 10-1''I O-n connected to a key telephone main device l.

Inside the key telephone main unit, there is a central processing unit (CPtJ).
2. A memory circuit (ME) that stores extension usage information.
MORY) 3 and button telephone interface circuit 4
but? L is equipped.

Each of the button telephones 1O-1 to 10-n includes a control data transmitting/receiving circuit 5. LCD display circuit6. L.C.
D display 7. Button press detection circuit 8 and display switching button 9
is installed. Note that since the internal configuration of only one button/telephone is shown in the figure, it will be simply referred to as the button telephone 10 hereinafter.

Next, the operation of this embodiment will be explained.

The central processing unit 2 in the button telephone 1 unit 221 determines whether the button telephone 10 is in use by identifying the control data sent via the control data transmitting/receiving circuit 5 of the button telephone 10. Result storage circuit 3
Next, when the display switching button 9 on the button telephone IO is pressed, the button press detection circuit 8 detects that the button has been pressed, and the button telephone 1 The data is sent to the device 211. The button telephone main device 1 receives control data indicating that the display switching button 9 has been pressed from the button telephone 10 through the button telephone interface circuit 4.

Furthermore, when the central processing unit 2 recognizes the control data, the central processing unit 2 uses the usage status information of the other key telephones 10 stored in the memory circuit 3 to calculate the LC of the key telephone 10.
It is converted into control data for displaying numbers or characters on the D-display 7, and transmitted to the button telephone 4i110 via the button telephone interface circuit 4. button telephone 10
Then, the control data is received by the control data transmitting/receiving circuit 5, and the LCD display circuit 6 drives and controls the LCD display 7 based on the received control data to display the usage status of the extension.

Figure 2 shows an L with 16 digits and 2 lines that can display numbers.
An example of displaying the extension usage status when using the CD display 7 is shown. In this case, the displayed number is the extension number currently in use. If the number cannot be displayed on the LCD display 7 at one time, by pressing the display switching button 9 again, the extension number currently in use will be displayed.

It should be noted that, of course, the button telephone 1O is equipped with a circuit 1, etc. that is generally provided in this type of telephone, and the - degree display switching button is also activated in the same way as when other buttons are pressed. If a certain amount of time has passed since 9 was pressed, the display on the LCD display 7 returns to the normal LCD display content.

[Effects of the Invention] As explained above, the present invention displays the extension usage status in numbers on the LCD display on the key telephone by pressing the display switching button on the key telephone. If you use display elements such as LEDs that are compatible with multiple extensions + t (direct transfer button), you can reduce the power consumption of the button telephone compared to the other party. Another advantage is that you can know whether the other party is using the telephone by simply pressing the display switching button without having to call the other party's key telephone.
