This restriction mode "0" or "1" is sent to the restriction class determination unit 83 via the restriction switch 79, and after judging the restriction state, one group of the restriction memory 85 is selected.

Reference numeral 85 is the regulation memory divided into 8 groups, and the information stored in the selected group is read out by exchanging information with the regulation judging section 84.

FIG. 6 shows an example of the regulation memory 85 divided into eight groups.

For example, the key telephone set 20 is divided into eight groups, which are divided into daytime regulation and nighttime regulation by the regulation memory 85. According to the restriction memory 85, the “0” group is not restricted because the dial of the all-button telephone 20 is “1”. However, the "1" group
Since the dials from 000 to 499 are "0", the daytime regulation is performed, and the dials from 500 to 999 are "1", the regulation is not performed. Similarly, in the "2" group, the numbers 000 to 499 are not restricted, but the numbers 500 to 999 are restricted. The "3" group is restricted from 000 to 999. In the "4", "5", "6", and "7" groups, the all-button telephone 20 is not restricted.

The daytime regulation of the key telephone device having such a configuration will be described with reference to the flowcharts of FIGS. 1, 2, 3 and 4.

First, the key telephone set 20 is classified into a daytime regulation class group and a nighttime regulation class group. For example, in the 200th key telephone set 20, as shown in FIG. 5, the "0" group is selected in the daytime restriction mode,
In the nighttime restriction mode, the "1" group is selected. 20
The number 1 button telephone 20 is "0" in the daytime restriction mode.
The group is selected, and the group "3" is selected in the nighttime restriction mode. Hereinafter, similarly, each button telephone 20
The daytime regulation mode group and the nighttime regulation mode group are determined.

After that, when the regulation key 62 of the key telephone 20 is set to the daytime regulation (S11), the setting signal indicates that the button telephone unit 25, the key input recognition section 71,
It is sent to the switching key state determination unit 73 via the key type determination unit 72. The output signal from the switch key state determination unit 73 is sent to the switch key state storage unit 76, the mode "0" of the daytime regulation state is stored therein, and the regulation switch 79 is output by the output signal from the switch key state determination unit 73. Is connected to the daytime regulation class storage unit 77.

As a result, the output signal of the daytime regulation class storage unit 77 is determined by the regulation class determination unit 83 via the regulation switch 79 (S12), and any one group of the regulation memory 85 is selected. When one group is selected, the established determination unit 84 is determined by the groups “0”, “1”, etc.
Is read out, the line is captured by the output signal, and the disconnection unit 82
Disconnect control.

When the line key 63a of the No. 200 button telephone 20 is pressed in this state, the line is captured via the button telephone unit 25, the key input recognition unit 71, the key type judgment unit 72, and the line key judgment unit 75. It is sent to the disconnecting section 82, and the line of the No. 200 key telephone 20 is captured.

Next, the button telephone 2 of the line No. 200
When the 0 dial operation is performed (S13), the button telephone unit 25, the key input recognition unit 71, the key type determination unit 7
2. One of the output signals is sent to the input dial storage unit 80 via the dial determination unit 74. Input dial storage unit 8
At 0, the output signal is accumulated (S14), and the information of the selected group is read from the restriction memory 85 and sent to the restriction determination unit 84. (See Figure 5).

In the "0" group of the No. 200 button telephone 20, since "1" is not restricted, the restriction judging section 84 judges that the daytime is not restricted (S15), and this non-restricting signal is sent to the line capture judging section 82. ..

On the other hand, since a dial signal is sent to the line capturing / disconnecting unit 82, this dial signal is sent as an unrestricted signal to the outside line unit 17 (S15), and a call with the outside line is performed.

Next, even when a telephone call is made using the 202nd key telephone 20, the line capturing / disconnecting unit 82 is controlled by the above operation. However, since the regulation class 77 is daytime, the determination unit 8 is determined by the output signal from the regulation class determination unit 83.
In 4, it is determined that it is daytime restriction (S15), and a signal for disconnecting the line capturing / disconnecting unit 82 is sent (S17).

Therefore, the 202nd key telephone set 20 is restricted, and a telephone call cannot be made. Even if the other button telephone 20 is used in the daytime, the 200th button telephone 20
Alternatively, it can be performed in the same manner as in the case of using the No. 202 button telephone 20.

Further, in the case of the nighttime regulation, it is possible to perform systematically by class or group as in the case of daytime regulation.

In the above-described embodiment, the key telephone is restricted to the daytime restriction and the nighttime restriction. However, other than this, it is also possible to perform the midnight restriction or the like.

[0035]

According to the key telephone device of the present invention, for example, daytime regulation and nighttime regulation can be easily systematically controlled for each group for the button telephone.
Not only the regulation can be done easily, but the handling operation of the key telephone and the wasteful telephone can be eliminated.
