Abstract

PURPOSE:To easily regulate the malicious call of mischief, etc., or incoming with erroneous connection by refusing an incoming call from a subscriber not to be registered. CONSTITUTION:An allowing calling person number registering and canceling circuit 11 registers a number, which is inputted from a number key 10, to an allowing calling person number storage device 7 according to the operation of an allowing calling person number registering and cancelling key 9 and executes registration cancel. An allowing number identifying device 8 detects whether an outgoing subscriber number, which is received with being included in the incoming call, is registered to the allowing calling person storage 7 or not. A refusing signal sending circuit 12 returns an irregal signal when the outgoing subscriber number of the incoming call is not an allowing calling person. Then, a line is disconnected. Thus, reception is not executed to an incoming side facsimile 6 and a fail alarm is outputted to an outgoing side facsimile terminal 1. Then, the malicious call is regulated.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a facsimile terminal.

[Conventional technology]

Conventionally, incoming calls to a facsimile terminal are automatically connected when automatic answering is set, and when manual answering is set, the called party answers and the connection is set.

Also, if the called subscriber name does not respond when setting manual response,
A pre-answer timeout causes the line to be restored in the same way as a telephone call.

[Problem to be solved by the invention]

When the conventional facsimile terminal mentioned above is set to auto-answer, it is always connected unless the incoming facsimile terminal is busy.
Since reception is performed, there is a drawback that malicious calls cannot be regulated regardless of whether it is during the daytime or during the day.

[Means to solve the problem]

The facsimile terminal of the present invention includes: a recording device; a means for registering a subscriber number in the storage device; and a means for canceling the registered subscriber number; It has means for detecting whether the subscriber number has been registered, and means for returning illegal information and disconnecting the line if the received calling subscriber number is not registered in the storage device.

[Effect]

() Since connection of incoming calls from subscribers who are not registered is rejected, malicious calls can be regulated.

(Example) Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an incoming call connection from another facsimile terminal to one embodiment of the facsimile terminal of the present invention.

In this embodiment, a facsimile communication call is made by a facsimile terminal 1, passes through an exchange 2 on the originating side, an outgoing trunk 3, an incoming trunk 4, and an exchange 5 on the terminating side, and then arrives at a facsimile terminal 6 on the terminating side.゜The facsimile terminal 6 is
Correction calling number storage device 7, permissible caller number registration/cancellation 1-9, permissible caller number 0 recording/cancellation circuit 11, permissible number identification device 8, rejection signal sending circuit 12, number key 10. have. The permissible calling number storage I device 7 is a storage device in which the subscriber numbers of the other subscribers to which the facsimile terminal 6 is permitted to receive are registered. The permissible caller number registration/cancellation key 9 is a key operated before inputting numbers 1 to 10 to determine whether to register or cancel the registration in the permissible optical revocation number storage device 7. The permissible calling number registration/cancellation circuit 11 registers the number inputted from the number key 10 in accordance with the operation of the permissible calling party number registration/cancellation key 9 in the corrected calling number storage device 7, and also cancels the registration. Let's do it. Permissible number identification device as,te detects whether the calling subscriber number received in the call is registered in the permissible calling number storage device 7. l'r'i rejection signal sending circuit 1
If the originating subscriber number of the incoming call is not the corrected calling name, then an illegal signal is returned and the line is disconnected.

As a result, the receiving side noax machine 6 does not receive the message, and a fail alarm is output to the calling side facsimile terminal 1.

〔Effect of the invention〕

As described above, the present invention has the advantage that by rejecting incoming calls from unregistered subscribers, it is possible to easily prevent malicious calls such as pranks and incoming calls due to erroneous connections.
