Next, the operation of the embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 3 is a flow chart of a control signal of the key telephone apparatus, FIG. 4 is a flow chart of a control signal of the key telephone, and FIG. 5 is a message display on the LCD of the key telephone according to the present invention. 5A is a message display immediately after the start of display, FIG. 5B is a message display shifted by one character, and FIG. 5C is a message display up to the last character of the message, and FIG. Is a message display including a message head symbol.

In FIG. 3, when a call or a function is set by operating the dial pad of the key telephone 9a, the key telephone 9a generates a dial pad input information signal A, and the dial pad input information signal A is transmitted to the button telephone 9a. Send to telephone interface circuit.

The key telephone interface circuit 3 comprises:
The control unit 4 converts the received dial pad input information signal A to obtain a control instruction signal B, and transmits the control instruction signal B to the control unit 4.

The control unit 4 that has received the control instruction signal B changes the state of the key telephone device 1 from the state stored in the state holding unit 13 to the new state.
Further, the control unit 4 generates a state signal C indicating a new state and transmits the state signal C to the display device driver 6 in order to create a message that visually conveys the state transition to the user.

The display device driver 6 comprises:
Based on the received status signal C, one or a plurality of basic messages, the number of digits of the basic message, and scroll display speed designation information are read from the basic message memory 14, and these basic messages are synthesized. , A message to be displayed on the LCD 11 of the key telephones 9a and 9m, and a message signal D including this message, the number of digits of the message, and scroll display speed designation information are obtained. Send.

Upon receiving the message signal D, the key telephone interface circuit 3 converts the message signal D into data suitable for the key telephones 9a and 9m to obtain message data signals E and F.
F is transmitted to the key telephones 9a and 9m.

Next, the signal flow of the telephone main unit 15 is shown in FIG.
This will be described with reference to FIG.

The message data signal G is the same as the message data signals E and F in FIG.

In FIG. 4, upon receiving the message data signal G, the main unit interface circuit 17 of the telephone main unit 15 converts the message data signal G to obtain a control unit input signal H, and converts the control unit input signal H to the telephone control signal. Transmit to the unit 19.

The telephone control unit 19 having received the control unit input signal H converts the message included in the control unit input signal H, the number of digits of the message, and the scroll display speed information into a memory information signal I, and outputs the message information I. It is stored in the memory 24. After the storage, the telephone control unit 19 transmits the LCD display instruction signal J to the LCD control unit 20.

LCD receiving instruction signal J for LCD display
The control unit 20 reads the message, the number of digits of the message, and the message display speed designation information from the message memory 24 to obtain a read signal K.

The LCD controller 20 compares the number of digits of the message to be displayed with the number of digits that can be displayed on the LCD 11 at one time from the read signal K.

As a result of the comparison, if the number of digits of the message to be displayed can be displayed on the LCD 11 at one time,
The LCD control unit 20 converts the message into an LCD drive signal L, drives the LCD 11 with the LCD drive signal L, and displays the entire message on the LCD 11 at one time.

On the other hand, if the number of digits of the message to be displayed cannot be displayed on the LCD 11 at one time, the LCD control unit 20 places the character before the first character 30 of the message as shown in FIG. A message prefix 29 is added to the message, and the message with the message prefix 29 is displayed on the LCD.
The LCD drive signal L is converted into a drive signal L.
1 is driven. Here, the message head symbol 29 is a symbol indicating the head of the message to the user.

Next, the driven LCD 11 is shown in FIG.
As shown in FIG.
The message display 31a is performed by the number of digits that can be displayed on the CD 11 at one time. At this time, the part that cannot be displayed on the LCD 11 is the message non-display 32a.

Next, as shown in FIG. 5B, the LCD control unit 20 shifts the message by one character from right to left based on the scroll display speed designation information, and displays the message on the LCD 11 at one time. The message display 31b is controlled to be displayed for a few minutes. At this time, the portion that cannot be displayed on the LCD 11 is the message non-display 32b.

Further, the LCD control unit 20 operates as shown in FIG.
As shown in (1), control is performed such that the message is shifted from right to left one character at a time until the last character 33 of the message is displayed on the LCD 11.

Next, as shown in FIG. 5D, the LCD control section 20 displays the last character 33 of the message on the LCD 11, and then continues to display the message start symbol 29.
Is displayed, and the display of the message is controlled so as to be repeatedly scroll-displayed from the top 30 of the message by the above-described method.

The scroll display speed is determined by the scroll display speed designation information stored in the message memory 14. As the scroll display speed designation information, the user inputs a scroll display speed desired by the user by operating the dial pad of the key telephone, and the scroll display speed is stored in the message memory 14 for each user of the main device 2. Information. By enabling the scroll display speed to be set by the user, the effect of following the message reading speed due to individual differences among users can be obtained.

[0044]

As described above, according to the present invention, since scroll display is automatically performed, the number of digits of a message is not limited by the fixed number of digits of the width of the LCD, and a long message is displayed. It is possible. As a result, by displaying a text that is more detailed and close to the natural language, it is possible to accurately inform the user of the state of the key telephone and error information of the operation of the key telephone, thereby greatly improving the operation efficiency of the key telephone. The service to the user is improved.
