Further, the display means 5 for displaying the destination status is composed of lamps 5a, 5b, 5c, etc. corresponding to the respective keys 4, 4, etc., and furthermore, these lamps 5a, 5b, 5c,... are two-colored, red and green, respectively. It is configured to perform display.

The destination status of the corresponding specific person is displayed based on the display status of the lamp, and the relationship between the display and the destination status is set as follows.

(1) Continuously lit in green... presence status (2) blinking green... indicates you are out of the room (3) continuously lit in red... indicates you are out The display is arranged in a cycle of dimming → red lighting → green lighting → green flashing → lighting off, and in response to the operation of the corresponding input key 4, the cycle progresses one step at a time for each key operation. The display state is switched. This switching of display states is performed under the control of a central control device 9, which will be described later.

Next, to explain the system configuration of FIG. 2, N1, N2, N3... are the telephone main bodies 1 shown in FIG. 1, and these plural telephones N ₁ , N ₂ ,
N ₃ . . . are each connected to the central control device 9.

The configurations of the telephones N1, N2, N3, etc. are the same, and for convenience, the configuration of the telephone N1 will be explained. 10 is a sub CPU, 11 is a ROM, 12
is a RAM, and the sub CPU 10 controls various functions according to the control program in the ROM 11.

13 is a keyboard section including a dial key 2 and input key groups 4, 4, etc. for inputting specific person change information, 3 is a line display, and 5 is composed of lamps 5a, 5b, 5c, etc. for displaying destination status. This is a display means.

The keyboard section 13, the line display 3, and the destination status display means 5 are connected to the input control circuit 1.
4 to the sub CPU 10, and a connection line from the input/output control circuit 14 to the central control unit 9 is led out.

On the other hand, the central control device 9 has a main CPU 15,
ROM 16 that stores control programs, stores various data, especially destination status information for specific people.
It mainly consists of a RAM 17 and an input/output control circuit 18, and connection lines from each telephone set N1, N2, N3, . . . are connected to the input/output control circuit 18.

The central control device 9 also has a clock circuit 19, and when the clock circuit 19 clocks a predetermined time, for example, 3 a.m., it outputs a control signal to the interrupt control circuit 20, which in turn outputs a control signal to the main CPU 15. Send an interrupt signal. In response to the interrupt signal, the main CPU 15 clears the specific person's destination state information, which will be described later, in the RAM 17.

FIG. 3 is a diagram showing the configuration of a memory section of the RAM 17 that stores destination status information regarding a specific person.

The memory section includes a lamp 5a of the telephone,
A display number information field A corresponding to 5b, 5c..., a field B holding the name or name of a specific person registered in advance corresponding to each of the display numbers, and a display number information column A corresponding to the display number corresponding to the specific person. A column C is configured to store the display state (destination state).

For example, the display number 1 in the display number information field A corresponds to the lamp 5a, and the display number 2 corresponds to the lamp 5b.
In addition, display number 1 is assigned to the president as a specific person, and display number 2 is assigned to the president as a specific person.
The Managing Director is assigned as a specific person.

Column C for storing each display state (destination state) is an initial state in which an interrupt signal is sent from the interrupt control circuit 20 to the main CPU 15 when the clock circuit 19 reaches a predetermined time (for example, 3 a.m.). Based on this, each lamp 5 of each telephone N1, N2, N3...
a, 5b, 5c, . . . are also turned off in response to an instruction from the central control device 9. After that, each telephone N1, N
When input key groups 4, 4, . . . for inputting specific person change information on the keyboard 13 of 2, N3, . . . are operated,
The central control unit 9 determines which telephone is the change information for which specific person, checks whether the change is possible, and if it is changeable, changes the display state of the specific person in accordance with the input instruction. For example, when the input key for a specific person is operated, if the display status of the specific person is currently off, it will change to a green continuous lighting state (occupation state), and if the current green continuous lighting state is currently lit, the display will turn green. If the information is rewritten as a blinking state (when you are out in another room) and the same input key is operated continuously, in the former case, the green continuously lit state will further change to a green blinking state. The information is rewritten from the green blinking state to the red lighting state (going out state), that is, the state is sequentially stepped up one step at a time according to the number of operations of the input key 4.

Furthermore, the central control unit 9 determines whether or not the change is possible based on specific person change information from each telephone, so that the destination status of a specific person cannot be freely changed from any telephone. .

In other words, it is assigned in advance that the destination status of the "President" as a specific person can be changed when an instruction to change the "President" is received from the president's telephone and/or the president's secretary's telephone, and each such specific person is The relationship between telephones that have been given the right to change is held in a memory portion (not shown), and this information is compared with specific person change information from the telephone.

For example, when the input key 4 corresponding to the president is operated from the president's secretary's telephone, specific person change information based on this key is sent to the central control device 9, and the central control device 9 determines which input key from which telephone 4 has been operated, and it is determined that the secretary's telephone has given a change instruction regarding the president. Check whether or not there is a right to change this, and if there is a right to change, information on the destination status of the specific person is sent. This is to rewrite the .

Next, the operation of the above configuration will be explained in detail. This operation is executed according to the operation flow shown in FIG. 4.

The central controller 9 is waiting for an interrupt signal or key information from each telephone, and by setting the clock circuit 19 to send an interrupt signal at a predetermined time, in this case 3 a.m., the central control device 9 waits for an interrupt signal or key information from each telephone. In response to the interrupt signal, the central controller 9 reads the RAM 1.
The part that stores the destination status information for the specific person in No. 7, that is, the column C in FIG. control to the state.

Then, for example, when it is time to go to work, when the input keys 4, 4, etc. are operated from each telephone N1, N2, N3, etc., the central control device 9 determines whether or not it is an instruction to input specific person change information (input key 4 is If it is specific person change information, it is checked whether or not there is a right to change as described above, and if there is a right to change, the specified person's destination status is changed in column C of RAM 17. is rewritten from off to continuously lit in green (in-room status), and the corresponding lamp of each telephone is controlled to be lit in green.

Also, when the input key 4 is operated twice in a row, the green light changes from continuously lit to green blinking (when the user is out in another room), and when the input key 4 is operated three times in a row, the green light changes continuously. The display switches from lighting to flashing green to lighting to red (outside state), and this is stored in column C of the RAM 17, and each lamp on the telephone is controlled to be lit in the above state.

After that, by changing the destination status of the specific person by operating the input key, RAM1 is
At the same time as the destination status in column C of 7 is rewritten, the display status of the corresponding lamp of each telephone changes accordingly.

Therefore, when a call is received from outside about a specific person or a visitor arrives, the destination status of the specific person can be known by looking at the lamp display on the telephone, and the response can be taken immediately. .

Although the above embodiment shows a configuration in which each input key 4 is arranged in correspondence with a specific person, the configuration is not limited to this. For example, a combination of a display change key and a numeric key can also be used. The configuration is as follows: press to set in change mode, then press the number keys to specify the display number, and then operate the display change key to change the display state, which is the destination state, one step at a time according to the number of operations. It goes without saying that the key input operation for instructing to change the destination state can take various forms.

Furthermore, regarding the display of the destination status of a specific person on each telephone, for example, the destination status of "President" may be displayed on the telephones numbered _N1 to _N9 , and the destination status of "Managing Director" may be displayed on the telephones numbered _N1 to _N15 . , _N5 to _N20 can display the destination status of "Managing Director", and the specific person whose destination is displayed can be arbitrarily changed depending on the telephone. This is the configuration of the RAM 17, which further stores the number of lamps (corresponding to the number of telephones) and the position of the corresponding lamps on each telephone for each specific person, as shown in Figure 5, and stores this information. It is controlled based on the
