The display is sequentially displayed in a cycle of green lighting - green blinking - red lighting - off, and in response to the operation of the corresponding input key 4, the display progresses through the cycle one step at a time for each key operation. A state switch takes place. 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 shown in Figure 2, Nl,
N2. N3... is the telephone main body 1 shown in FIG. 1, and these plural telephones N1, Nz, Ns.
... are connected to the central control device 9, respectively.

The telephones Nl, N2. N3-... have the same configuration, and for convenience, we will explain the configuration of N1 telephone as follows:
10 is a sub CPU, and 11 is a ROM.

Reference numeral 12 denotes a RAM, and the sub CPU 10 controls various functions according to the control program of the ROMII.

13 is a keyboard section including a dial key 2 and a group of input keys 4, 4 for inputting specific person change information, 3 is a line display, and 5 is a lamp 5a*5b, 5c, .・It is a display means consisting of.

The keyboard section 13. The display means 5 for displaying the destination status of the line display 3I is connected to the sub-C via the input control circuit 14.
PU10, 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 includes a main CPU 15 and a ROM 16 that stores control programs. It mainly consists of a RAM 17 that stores various data, especially destination status information for a specific person, and an input/output control circuit 18, and each telephone Nl, N2
．． Connection lines from N3... are connected to the input/output control circuit 18.

Further, the central control device 9 has a clock circuit 19, and when the clock circuit 19 clocks a predetermined time, for example, 3:00 a.m., it outputs a control signal to the interrupt control circuit 20, and the interrupt control circuit 20 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 lamps 5a + 5b of the phone.
, 5c..., a display number information field A corresponding to each of the above-mentioned display numbers, a field B holding the name or name of a specific person that has been ringed in advance, and a display number information field corresponding to the above-mentioned specific person. A column C is configured to store the lamp display state (destination state).

The display number 1 in the display number information column A is, for example, the lamp 5a.
In addition, the display number 2 corresponds to the lamp 5b, and the display number 1 is assigned to the president as a specific person, and the display number 2 is assigned to the managing director as a specific person.

The column C that stores each display state (destination state) is
In the initial state, the clock circuit 19 is set at a predetermined time (for example, 3 a.m.).
time), the interrupt control circuit 20 sends the main CPU
An interrupt signal is sent to the telephones N1.15 and the telephones N1. N2. N3...
・Each lamp 5a.

5b, 5c, . . . are also turned off in response to an instruction from the central control device 9. After that, each phone Nl, N2゜N3...
When the input key group 4.4 for inputting specific person change information on the keyboard 13 is operated, the central control unit 9 determines from which telephone the change information is for which specific person, and the change information can be changed. If the display status of the specific person can be changed, the display status of the specific person is changed according to the input instruction. For example, if the entry key for a specific person is operated,
If the display status of the specific person is currently off, the display will turn green continuously (occupied), and if the display status of the specific person is currently lit continuously, the display will blink green (going to another room). If the information is rewritten and the same person's key is operated continuously,
In the former case, the information is rewritten from the green continuous lighting state to the green flashing state, and in the latter case, the information is rewritten from the green flashing state to the red lighting state (outing state).
The state is sequentially stepped up one step at a time according to the number of operations.

Furthermore, the central control unit 9 determines whether or not change is possible based on specific person change information from each telephone set, in order to prevent the destination status of a specific person from being changed from any telephone. be.

In other words, it is assigned in advance that the destination status of 1 president 1 as a specific person can be changed when a change instruction for 1 president 1 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 an 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 telephone input key 4 corresponds to the president. Determine whether Kaki-4 has been operated,
The system determines that the secretary's telephone is instructing a change regarding the president, checks whether or not there is a right to change this, and if there is a right to change, the destination status information for the specific person is rewritten.

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 control unit 9 rewrites the portion of the RAM 17 that stores destination status information for a specific person, that is, column C in FIG.
The lamps 5a, 5b+5c'...)5 are controlled to be turned off.

Then, for example, when it is time to go to work, each telephone N1
．． N2. When input keys 4, 4, . 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 destination status of the designated specific person in column C of the RAM 17 is changed from off to continuously lit green ( occupancy status), and controls the corresponding lamp of each telephone to turn green.

In addition, 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. The sequence changes from continuous lighting to flashing green to red lighting (outside state), and this is stored in column C of the RAM 17, and each lamp of the telephone is also controlled to be lit in the above state.

After that, by changing the destination status of a specific person by operating the input key, the destination status in column C of RAM 17 is rewritten according to the above procedure, and at the same time, the display status of the corresponding lamp on each telephone changes accordingly. .

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

In addition, in the above embodiment, each person has four oysters corresponding to a specific person.
..., but the configuration is not limited to this, for example, it is possible to use only a combination of the display change key and the numeric key. The configuration may be such that the display number is specified and the display change key is operated to change the display state, which is the destination state, one step at a time depending on the number of operations.There are various key manual operations for instructing the change of the destination state. Of course, the following modes can be adopted.

In addition, the destination status of a specific person can be displayed on each phone, for example, N! If you display the destination status of ``President 1'' on the phone of ~N, display the destination status of ``Managing Director 1'' on the phones of N1 to N15, and display the destination status of ``Managing Director 1'' on the phone of Ns'''Nzo. As mentioned above, it is also possible to arbitrarily change the specific person whose destination is displayed depending on the telephone. This is RAM
17, the number of lamps (corresponding to the number of telephones) and the position of the corresponding lamps on each telephone are further stored for each specific person, as shown in FIG. It is something to be controlled.

Effects> As described above, in the present invention, each presence is provided in correspondence to one or more predetermined specific persons.
