Abstract

PURPOSE:To efficiently terminate picture information by switching a line to another facsimile equipment at the time of trouble detected on a terminating facsimile equipment by a trouble monitor part. CONSTITUTION:An incoming detecting part 2 which detects incoming signal to a connected line, a trouble monitor part 3 which monitors whether a terminating facsimile equipment 5 (6) is in trouble or not, and a switching part 4 which switches the terminating line to another facsimile equipment 6 (5) at the time of trouble detected on the terminating facsimile equipment 5 (6) by the trouble monitor part 3 are provided. If the terminating facsimile equipment 5 (6) cannot receive picture signal because it is in trouble or not set to the automatic reception state, the line is automatically switched to another facsimile equipment 6 (5) installed in the same position. Thus, picture information is efficiently terminated.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention, when it is recognized that a failure has occurred in a facsimile machine connected to a line, automatically sends a message to another facsimile machine connected to this line. This invention relates to an automatic incoming call switching device for a facsimile machine that switches the number of calls at the same time.

[Conventional technology]

Generally, in a facsimile machine, one tree line and one facsimile machine are connected on a one-to-one basis.

(Problem to be Solved by the Invention) Therefore, when a facsimile machine receives a call, if the machine malfunctions due to no recording paper or jammed recording paper, or if automatic reception is not set by the operator, the image information will not be received. can't do it. Even if two or more facsimile machines are installed at the same location, there is a problem in that image information cannot be received in place of a faulty facsimile machine.

The object of the present invention is to provide a system in which two or more facsimile machines are installed, and if the incoming facsimile machine cannot receive image information because it is malfunctioning or is not set to automatic reception, the facsimile machines installed at the same location can To provide a user of a facsimile device with more reliable facsimile communication by automatically switching the line to another facsimile device, and having the other facsimile device receive image information on its behalf.

[Means to solve the problem]

The automatic incoming call switching device for a facsimile machine according to the present invention includes an incoming call detection unit that detects an incoming call on a connected line, a failure monitoring unit that monitors whether the incoming facsimile machine is out of order, and If the device is detected to be faulty by the fault monitoring unit,
The facsimile apparatus is equipped with a switching unit that switches the incoming line to another facsimile machine.

[Effect]

In this invention, if the incoming facsimile machine cannot receive image information because it is out of order or not set to automatic reception, the line is automatically switched to another facsimile machine installed at the same location.

〔Example〕

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The part surrounded by a broken line in FIG. 1 shows an automatic call switching device 10 for a facsimile machine according to the present invention. In this figure, 1 is the line connected to the facsimile machine, 2 is an incoming call detection unit that detects that the facsimile machine has received a call, 3 is a failure monitoring unit that monitors whether the facsimile machine that received the call is out of order, and 4 is a a switching unit that switches the incoming line to another facsimile machine in the event of a failure of the facsimile machine; 5 is a facsimile machine connected to the line 1;
6 is the line 1 when the facsimile machine 5 is out of order.
The other facsimile devices connected to the fax machine are shown respectively. Note that the facsimile device 6 is connected to line 1 of the facsimile device 5.
(not shown), and normally both facsimile machines 5.6 operate independently of each other.

FIG. 2 is a state transition diagram for explaining the operation of the embodiment shown in FIG. The operation of the embodiment shown in FIG. 1 will be explained using this state transition diagram. Note that (a) to (C) indicate each step.

In step (a), the fact that there is an incoming call on the four wire 1 connected to the facsimile machine 5 is detected by detecting a 16Hz ringing signal in the case of an incoming call from an analog network, and by detecting a ringing signal of 1300) (z) in the case of an incoming call from a facsimile network. Detection of incoming calls from the digital network is performed by the incoming call detection unit 2 by detecting the facsimile call code, etc., and the failure monitoring unit 3 notifies the failure monitoring unit 3 of the facsimile machine. If the facsimile machine 5 does not respond within a certain period of time after detecting a paging signal or a 1300 Hz paging signal from the facsimile network, or if the digital facsimile machine detects a fault code on the called side that is notified to the digital network, the facsimile machine 5. At this time, step (b)
If the facsimile machine 5 responds normally, it returns to the idle state, and if an abnormality is detected in step (c), the switching unit 4 connects the line 1 from the normally connected facsimile machine 5 to the facsimile machine 6. to receive image information.

In this way, even if the facsimile machine 5 is out of order, by having the facsimile machine 6 perform reception, facsimile communication can be performed without any trouble.

The automatic call switching device 10 for a facsimile machine according to the present invention may be configured separately from the facsimile machine 5, or may be incorporated into the facsimile machine 5.

(Effects of the Invention) As explained above, the present invention includes an incoming call detection unit that detects an incoming call on a connected line, a failure monitoring unit that monitors whether the incoming facsimile machine is out of order, and The system is equipped with a switching unit that switches the line to another main facsimile machine when a fault monitoring unit detects that the facsimile machine is malfunctioning. This has the advantage that image information can be received without waste by switching the line to another fudge device installed at the same location.
