Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone apparatus for displaying a plurality of local line states on a telephone.

2. Description of the Related Art FIG. 5 shows a block diagram of a conventional key telephone apparatus on the telephone side, which includes a microcomputer 5 having an arithmetic control unit 1, a storage unit 2, an input unit 3, and an output unit 4 therein. A key matrix unit 6 for inputting data to the input unit 3; a main unit telephone communication receiving unit 7 for receiving a dial or line state display command from the main unit; LCD driver 8 and LCD dial display section 9 for dynamic display;
Similarly, an LED driver 10 for dynamically displaying local line status data from the output unit 4 and a two-color local line LED display unit 11
It is composed of

When display data is input to the input unit 3, the arithmetic and control unit 1 determines whether the data is dial data or line state data.
A dynamic display is performed on the dial display unit 9, and in the case of the office line status data, the LED driver 10 and the two-color LED office line display unit
The dynamic display is performed at 11.

Further, the two-color local line display section 11 is simply replaced with an LCD, and L
LCD driver display 9 and LCD station line display 11 with CD driver 8
It may control both.

However, the above-mentioned conventional key telephone apparatus uses an LED for displaying a line state and an LCD for displaying a dial.
In order to use this, many components are required, the configuration becomes complicated, and the cost becomes high. Also, in bright places (sun,
Under the electric lamp, there is a problem that it is difficult to see the local line status display by the light emitting type two-color LED.

On the other hand, a telephone that simply uses an LCD instead of a two-color LED for the line status display has a problem that it is difficult to understand because a complicated status display (six or more types) is displayed only by blinking.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide an excellent key telephone device capable of displaying a line state easily on an LCD.

Means for Solving the Problems In order to achieve the above object, the present invention creates a white or black inversion mark indicating whether a line is used by its own telephone or by another telephone. This mark is blinked and displayed on the LCD according to the local line state.

According to the above configuration, the present invention uses the white or black inversion mark to indicate whether the own telephone is using the office line or another telephone is using.
By displaying the line state on the LCD so as to indicate a state such as a hold state, the line state display can be easily understood. In addition, the line status display and dial display are displayed on the LCD.
By displaying the keypad, there is an effect that the key telephone device can be configured at low cost.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the key telephone apparatus according to the present invention.

In FIG. 1, 21 is key data input means for inputting key data by key operation, and 22 is a main unit (not shown).
Means for receiving communication commands from the main unit telephone which receives a display command from the user; 23, a dial display data creating means for creating dial display data; 24, a white / black mark for creating a white / black mark according to the own use station line / others use station line. Black mark creation means, 25 is a blinking display creation means for blinking a white / black mark depending on the state of the line such as incoming call, call, hold, etc., 26 is an LCD display driver output for outputting dial and line state display data to the LCD driver Means.

FIG. 2 is a block diagram showing a specific hardware configuration of the present embodiment. In FIG. 2, reference numeral 27 denotes an operation control unit 2 therein.
8, a microcomputer having a storage unit 29, an input unit 30, and an output unit 31; 32 is a key that comprises a dial key and a function key such as a line key and sends a signal to the input unit 30 of the microcomputer when pressed. A matrix unit, 33 is a main unit telephone communication receiving unit that receives a dial or line display status command from the main unit, and 34, 35 are dial stations that receive dial data from the output unit 31 of the microcomputer 27 and perform dynamic display. LCD driver for line display and L
This is a CD display unit.

Next, the operation of this embodiment will be described with reference to a flowchart under the control of the microcomputer 7 shown in FIG.

When display data is input to the input unit 30 of the microcomputer 27 from the key matrix unit 32 or the communication reception unit 33 between the main unit telephones by an operator's key operation or a change in the line state, the line line data is inputted in step 36. And dial data, and if it is dial data, dial data is set in step 43.

In the case of the office line data, the flow shifts to step 37, where it is determined whether the office line is the own office line or the other office line. In the case of the own station line, a black mark is set in step 38, and in the case of another station line, a white mark is set in step 39. In either case, the process proceeds to step 40, and the local line state is determined this time.

If the office line state is busy, the display is turned on in step 41, and the other states are flashed in step 42. When the LCD station line display data and the dial data described above are output to the LCD driver 34 in step 44, the own station line is displayed by lighting or blinking with different frequencies as shown in FIG.
Along with the distinction of other office lines, it is possible to display the state of the office line for incoming, talking, and holding.

Effects of the Invention The present invention has the following effects, as is apparent from the above-described embodiments.

(1) With the white or black inversion mark and flashing,
In addition to distinguishing between other lines, incoming, talking, and
Because it is displayed on the LCD, the display can be larger than the LED, making it very easy to understand even in bright places.

(2) Since a total of six types of dial display of incoming / outgoing call, telephone call and hold, and local line status display or local line status display can be displayed only on the LCD, a key telephone device can be configured at low cost.
