2. Description of the Related Art A conventional private branch exchange for displaying an absent message will be described below with reference to FIG. In FIG. 4, reference numeral 110 denotes a dial operation unit of the extension telephone for inputting an absent message number, start time, and end time. 100 is a private branch exchange, 101 is a message memory unit for storing the abcent message number, start time, and end time input from the dial operation unit 110 of the extension telephone. Is provided. Reference numeral 102 denotes a system message memory unit capable of storing, for example, up to 10 message contents corresponding to the absent message number, and 103 denotes a system message memory based on the absent message number at the current time between the start time and the end time. A message creation unit for creating an absent message part using the corresponding message content converted by the unit 102; a message sending management unit 104 for sending the created absent message sentence to a message display unit of the extension telephone; Reference numeral 105 denotes a time management unit which manages the current time and generates a start signal at regular intervals to start the message transmission management unit 104. 111 denotes an absent message and a time message transmitted from the message transmission management unit 104. It is a message display part of the extension telephone displayed above.

The operation of the conventional private branch exchange constructed as described above will be described below. First, the absent message number / start time / end time data input from the dial operation unit 110 of the extension telephone is stored in the message memory unit 101 provided corresponding to each extension telephone. Next, the message memory unit 101 of the private branch exchange 100
The operation of displaying an absent message based on the data described in the above will be described with reference to the flowchart of FIG. In step 201, the message sending management unit 104 is started by the time management unit 105 at a constant (1 minute) cycle. Next, in step 202, the message sending management unit 104 obtains the current time from the time management unit 105. In step 203, the current time is compared with the absent message start time in the time storage unit a of the message memory unit 101 to determine the absent message. Determines if the time has come to display the message. At step 204 corresponding to the corresponding time, the absent message number stored in the message storage section b of the message memory section 101 is obtained.

Next, in step 205, the message creating unit 103
Stores the absent message corresponding to the acquired absent message number in the system message memory section.
An absent message sentence is created by adding the start time and end time, obtained from 102. Next, at step 206, the created absent message is displayed by the message display section 111 of the extension telephone, and at step 209, the process is terminated. At this time, when a new absent message is displayed, the conventional absent message is automatically cleared.

If the present time does not correspond to the absent message display start time, the current time is compared with the absent message end time in step 207. If it does not correspond to the end time, the process ends in step 209. If it corresponds to the end time of the absent message, step 208
Then, the absent message sentence currently displayed through the message display unit 111 is cleared, and the process is terminated in step 209.

The absent message displayed on the extension telephone in this manner is transferred to the extension telephone calling the extension telephone by data transfer means (not shown), and the message display section thereof Is also displayed on the display, so that the state of the called extension telephone can be known.

[0007]

However, in the above-mentioned conventional configuration, setting and changing of the absent message can be performed only by the extension telephone set with the absent message. When it is necessary to make a change, a corresponding extension telephone is required, and it is difficult to transmit an accurate absent message to the other party according to time.

The present invention solves the above-mentioned problem and provides an automatic private branch exchange which can set and change an absent message by designating a corresponding extension telephone number.
