Description

[0001]
[Industrial application fields]
The present invention relates to a facsimile machine.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a facsimile apparatus having a function of rejecting an incoming call for an incoming call other than a specific destination is known.
[0003]
This facsimile apparatus has means for registering a telephone number that permits an incoming call, and refers to the other party's telephone number by checking a TSI signal sent from the other party's machine, and is a telephone number that permits an incoming call. Continues the facsimile communication, and interrupts the facsimile communication if the telephone number rejects the incoming call. When the incoming call is rejected, the other party's telephone number is displayed.
[0004]
[Problems to be solved by the invention]
However, in the above conventional example, there is a problem that facsimile communication is rejected for all telephone numbers that are not registered as telephone numbers that permit communication.
[0005]
In addition, when the incoming call is rejected, the TSI signal information is displayed as the telephone number information of the other party so that the user can understand it. When there are a lot of destinations, users have trouble re-calling.
[0006]
In particular, since the information on the TSI signal is output by the counterpart facsimile machine, there is a case where the information does not necessarily match the actual telephone number, and there is a case where the other party cannot be accurately grasped.
[0007]
SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can appropriately cope with an incoming call from a destination that is not registered as a telephone number that permits an incoming call.
[0008]
[Means for Solving the Problems]
The present invention relates to a registration means for registering the purpose of a telephone call or facsimile communication corresponding to a telephone number of a partner apparatus, and a communication line sent before connecting to the partner apparatus in response to an incoming call. Depending on the telephone number identifying means for identifying the telephone number of the incoming calling apparatus, the telephone number of the calling apparatus identified by the telephone number identifying means, and the telephone number registered in advance by the registering means The incoming call notification means for visually displaying that the incoming call has been received without ringing the call, and the incoming call notification means for visually displaying the identified telephone number; If the call response is instructed to control to respond to the incoming call, further, the telephone number of the calling device identified by the telephone number identification means, by said registration means facsimile If it is registered as a telephone number for communication purposes, it will automatically respond in response to detection of an incoming call, start facsimile communication, and if it is registered as a telephone number for call purposes, it will ring. And a control means for controlling the facsimile apparatus.
[0009]
As a result, when there is an incoming call from a destination that does not permit facsimile communication or telephone call, the user can be notified that the incoming call is received in a quiet environment without ringing. Before charging occurs on the calling side, it is possible to decide whether to answer after checking the telephone number of the calling side. Further, it is possible to appropriately perform facsimile communication / call processing according to the telephone number on the calling side .
[0010]
For example, if the user is busy, the device rejects the incoming call as it is without seeing a visible incoming call. If you are not so busy, you can see the incoming call and respond . Further, since the facsimile communication and the operator's ringing are automatically performed according to the telephone number on the calling side, the load on the user can be reduced.
