Abstract

PURPOSE:To avoid the chance of facsimile reception from being lost by storing the station number of a calling station when the facsimile reception function is disabled and dialing the station number of the stored calling station at the restoration of reception function so as to apply facsimile reception. CONSTITUTION:When a call requesting facsimile reception is generated from a transmitter 22 with a facsimile receiver 11 used as a printer, the facsimile receiver 11 stores the station number infomation of the transmitter 22 and also informs that the reception function is disabled at present to the transmitter 22. Further, when the facsimile reception function is restored, a dial pulse is transmitted sequentially to a line 20 based on the station number information of a remote station stored. This dial pulse reaches an exchange 21, where a ringing signal is transmitted to the transmitter 22. Thus, the line is established and the communication control using the caller side as the reception is conducted.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a facsimile receiving device that can also be used as a printer.

Conventional configurations and their problems In recent years, with the wave of office automation, as part of the efficient use of facsimile receiving devices, the recording function of facsimile receiving devices has come to be used also as a printer.

FIG. 1 is a schematic diagram of a conventional printer-type facsimile receiver. The facsimile receiving device 1 is connected to the line 2.
network control means 5 which controls the connection between the telephone 3 and the modulation/demodulation means 4, the modulation/demodulation means 4, the recording means 6, and the external computer 7 which controls the connection between the modulation and demodulation means 4 and the recording means. and a switch 8 for switching between the two.

Note that the line 2 can be connected to a facsimile transmitter 10 via an exchange 9.

When receiving a facsimile, first the facsimile transmitter 1
A line 2 is established between O and the facsimile receiving device 1 through the exchange 9. When establishing this line 2,
The switching signal sent from the exchange 9 is transmitted to the network control means 5.
is detected, and an operation is performed to switch the connection to the line 2 from the telephone set 3 to the modulation/demodulation means 4. After communication control is performed between the facsimile transmitting device 10 and the facsimile receiving device 1, a facsimile signal is sent from the facsimile transmitting device 1o to the facsimile receiving device 1. After the facsimile signal arrives at the facsimile receiving device 1, it is converted into a recording signal by the modulation means 4, and is inputted to the recording means 6 through the switch 8 connected as shown by the broken line to obtain a recording surface.

On the other hand, when the facsimile receiving device 1 is used as a printer for the computer 7, the recording signal output from the computer 7 is input to the recording means 6 through the switch 8 connected as shown by the solid line, and a recording surface is obtained. .

However, there is one problem with the above-mentioned facsimile receiving apparatus that also functions as a printer.

The problem is how to handle a call requesting facsimile reception while the facsimile receiving apparatus is being used as a printer.

The easiest way to deal with this is to not accept facsimile reception. That is, even if a ringing signal is input to the facsimile receiving apparatus 1 and the network control means 5 detects the ringing signal, it is controlled to ignore it. However, in this case, since the network control means 5 connects the line 2 and the telephone set 3, the telephone set 3 continues to ring.

This is very noisy and can be overheard by people living near the facsimile receiving device 1. Then, because of the excessive noise, the person picks up the phone, says a disclaimer that the facsimile receiving device 1 is currently being used as a printer, and then hangs up. However, such unproductive work should be eliminated. If this is the case, a method would be to incorporate a voice response device into the facsimile receiving device 1 and have the machine decline the call instead of a person declining the call.

It will be done.

However, with the above method, the opportunity to receive a facsimile is still missed, and when considering the workability of the operator of the facsimile transmitting device 1o, the above method is inconvenient.

Therefore, when considering ways to not miss the opportunity to receive a facsimile, the following methods may be considered.

That is, if the facsimile receiving device is equipped with a large-capacity memory and there is a request for facsimile reception, it will receive the request in the same way as normal facsimile communication and perform the facsimile reception operation, but the recorded signal obtained by the modulation/demodulation means 4 will be , once stored in the large capacity memory, and after the use as a printer is completed, the recorded signal stored in the large capacity memory is taken out, and the recorded signal is input to the recording means to obtain the recorded surface. It is.

However, in this case, an expensive large-capacity memory is required, making the facsimile receiving apparatus expensive.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and provides a facsimile receiving device that can also be used as a printer without using an expensive large-capacity memory and without losing the opportunity to receive facsimile. The purpose is to

Composition of the Invention The present invention comprises a recording means, a modulation/demodulation means, and a switch for switching input to the recording means between the modulation/demodulation means and an external input means, and when the facsimile reception function is disabled, the area number of the calling station can be changed. By detecting and memorizing it, and then dialing the memorized station number of the calling station when the facsimile receiving function is restored after use as a printer, the machine receives a facsimile without using expensive large-capacity memory. This is to compensate for the loss of opportunities to receive facsimile.

Description of examples Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a schematic block diagram of a facsimile receiving apparatus showing an embodiment of the present invention. In FIG. 2, 11 is a facsimile receiving device that also serves as a printer, 12 is a network control means, 13 is a modulation/demodulation means, and 14 is a recording means 15 is a switch for switching input to the recording means 14. 16 is a communication control means for controlling the modulation/demodulation means to control communication with the facsimile transmitting device 22 and detecting the other party's station number;
Reference numeral 17 is a partner station number storage means for storing the partner station number detected by the communication control means 16, and 18 is a dial pulse generating means for automatically generating a dial pulse. 19 is a telephone, 20 is a line, 21 is an exchange 122 is a facsimile transmission device, and 23 is a computer.

The operation of the facsimile receiving apparatus having the above configuration will be explained below. First, to explain how the facsimile receiving device is used as a printer, the switch 16 is connected as shown by the broken line, the recording signal output from the computer 23 is input to the recording means 14 via the switch 15, and the recording surface is reproduced. be done. At this time, the facsimile receiving device 11 is in a state in which the facsimile receiving function is disabled.

In this way, when a call requesting facsimile reception occurs from the facsimile transmitting device 22 while the facsimile receiving device 11 is being used as a printer, the line 2
The network control circuit 12 detects the ringing signal inputted from the telephone 19 to the telephone 19 and connects it to the telephone m20.
Switch to 3. Next, send the communication control signal by fax+)
Through the exchange between the transmitting device 22 and the facsimile receiving device 11, the facsimile receiving device 11 notifies the facsimile transmitting device 22 that the facsimile receiving function is currently disabled, and also obtains the area number information of the facsimile transmitting device 22.

By the way, a communication control signal is a bit pattern of 0 and 1 modulated with a fixed carrier wave, and the meaning of the bit pattern is determined in advance between the facsimile transmitting device 22 and the facsimile receiving device 11. If you keep it,
Any information can be exchanged. For example, when the second bit of the communication control signal transmitted from the facsimile receiving device 11 to the facsimile transmitting device 22 is 1'',
The bits after the 10th bit of the communication control signal transmitted from the facsimile transmitter 22 in response to the communication control signal indicating that the facsimile reception function is disabled indicate the station number of the facsimile transmitter 22. It is best to decide on such matters in advance.

By exchanging communication control signals as described above, the communication control means 16 of the facsimile receiving apparatus 11 can detect the station number of the facsimile transmission apparatus 22 from the information obtained by demodulating the communication control signal with the modulation/demodulation means 13. The station number of the facsimile transmitting device 220 detected in this way is stored in the destination station number storage means. Then, the line 20 is temporarily disconnected.

Note that on the facsimile transmitting device 22 side, the transmitted original (
A document (not shown) is placed on a document table (not shown) and left unloaded. That is, the operator of the facsimile transmission device 22 only needs to perform the transmission operation once and then leave it alone.

Next, when the computer 23 outputs all the recording signals and the use of the facsimile receiving device 11 as a printer is completed, the switch 15 is connected as shown by the solid line, and the facsimile receiving function is restored.

When the facsimile receiving function is restored, the other party's station number storage means 17 outputs the stored station number information of the facsimile transmitting apparatus 22 to the dial pulse generating means 18. Upon receiving this, the dial pulse generating means 18 sends a dial pulse to the primary sequential line 20 based on the area number information. At this time, the network control means 12 connects the line 20 and the dial pulse generation means 18.

The dial pulse sent from the facsimile receiving device 11 reaches the exchange 21 through the line M20, and the exchange 21 sends a ringing signal to the facsimile transmitting device 22. A line is established by 0, and the calling party receives the communication. Control takes place. Then, an image signal obtained by automatically reading and scanning the transmission document on the document table of the facsimile transmitting device 22 is modulated by a modulation circuit (not shown) to generate a facsimile signal, which is then transmitted by facsimile. It is transmitted from the device 22. This facsimile signal reaches the facsimile receiving device 11 through the line 20, and is demodulated by the modulation/demodulation means 13 to become a recording signal. This recording signal is passed through the switch 15 to the recording means 14.
The recording surface is obtained.

Note that the network control means 12 connects the line 20 and the modulation/demodulation means 13 when the line is established.

As described above, according to this embodiment, even if there is a call requesting facsimile reception while the facsimile receiving device is being used as a printer, the work efficiency of the operators on the sending and receiving sides will be degraded. This makes it possible to compensate for the loss of opportunities to receive facsimile.

Note that although the above description has been made regarding only one embodiment of the present invention, the present invention is not limited thereto. For example, although the present invention relates to a facsimile receiving device, it goes without saying that it can also be applied to a type that can be used for both transmission and reception. Further, in this embodiment, a dial pulse generating means is used as the calling means, but a two-frequency calling means may be used instead.

Effects of the Invention As is clear from the above explanation, when a facsimile receiving device used as a printer receives a call requesting facsimile reception, the present invention detects the station number of the other party, memorizes it, and transmits it to the printer. After the end of use as a fax machine, the machine calls the other party's station number based on the memorized station number and receives the facsimile, making it possible to compensate for the loss of the opportunity to receive a facsimile without requiring a large capacity memory. requires no additional effort on the part of the operator.
Work efficiency can be improved.
