Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device having a polling function.

[Conventional technology]

Conventionally, facsimile machines have been known that have a polling function that transmits documents, images, etc. to the originating station when it receives a polling instruction signal from the originating station (Japanese Patent Laid-Open No. 62-29363). , Japanese Patent Publication No. 62-284
Publication No. 571).

Since this type of facsimile device automatically transmits a document even if a polling instruction is received due to a wrong call, there is a risk that confidential information written on the document may be leaked.

To protect against this erroneous dialing, for example, when a polling instruction signal is transmitted from a transmitting station, a PIN code is sent at the same time, and the receiving station determines whether or not to accept the polling instruction signal based on this PIN code. Various manufacturers have proposed facsimile machines equipped with

[Problem to be solved by the invention]

However, since the facsimile apparatus described above does not necessarily have two protection measures depending on the manufacturer, there is a problem that polling operations cannot be instructed if the originating station and the receiving station are made by different manufacturers.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile device that can issue a polling operation instruction even when the facsimile devices of the originating station and the receiving station are made by different manufacturers.

[Means to solve the problem]

The present invention provides a facsimile device that transmits a document to a calling station when a polling operation instruction is received from the calling station, and a dial tone detection unit that detects a dial tone signal from the calling station, and a preset dial sound storage means for storing a dial sound; dial sound determination means for determining whether a dial sound signal detected by the dial sound detection section matches the stored dial sound; and the dial sound determination means. and polling control means that performs a polling operation when it is determined by the means that the device is compatible.

[Effect]

According to the facsimile device having the above configuration, when a polling operation instruction is received from the originating station, a dial tone signal from the originating station is detected, and this dial tone signal is converted into a preset and stored dial tone. If it matches, perform polling operation.

(Embodiment) FIG. 1 shows a block configuration of an embodiment of a facsimile apparatus according to the present invention.

The facsimile machine includes a network control section 1, a modem section 2, a reading section 3, a recording section 4, a storage section 5 having a function as a dial tone storage means, an operation section 6, a mechanical section 7, - a dial tone detection section 8, and a central control section 9 having functions as a dial tone determining means and a polling control means.

The network control section 1 connects the telephone line to the apparatus when a paging signal is received, and releases the telephone line from the apparatus when the polling operation is completed. The modem section 2 modulates the transmission signal from this device,
The signal is transmitted to the telephone line via the network control unit 1, and the signal received from the telephone line is demodulated.

The reading section 3 reads a document or the like as an image signal, encodes it, and outputs it to the central control section 9.

The storage unit 5 stores a password code, a polling code, a message such as a voice, an image signal read by the reading unit 3, and the like. The operating section 6 is for operating the device from the outside.

The mechanism section 7 is for driving the reading section 3 and the recording section 4. The dial tone detection section 8 detects a dial tone signal from a calling station. Note that this dial tone signal refers to a signal transmitted by dialing at a calling station.

The central control unit 9 includes a network control unit 1, a modem unit 2,
It controls the reading section 3, the recording section 4, the storage section 5, the mechanism section 7, and the dial tone detection section 8.

Note that the recording unit 4 decodes the received code signal into an image signal and prints it on recording paper or the like.

Next, the operation of the present invention will be explained using the flowchart shown in FIG.

First, when a calling signal from a calling station is received in step S1, a telephone line is connected to the present device by the network control section 1 in step S2.

Then, in step S3, a message is sent to the calling station to dial a polling code to select a polling operation.

In step S4, it is determined whether or not a dial tone signal has been sent from the calling station within a predetermined time. If the dial tone signal is not received, the telephone line is disconnected from the device in step S10 without performing the processing from step $5 onwards. It will be released. Further, when a dial tone signal is sent in step S4, in step S5 it is checked whether or not this dial tone signal matches the dial tone as a polling code stored in the storage section 5. It is determined whether the dial tone and the dial tone signal match or whether the dial tone is included in the dial tone signal.

Then, when the dial tone signal does not match the polling code, the telephone line is released from the device without performing the processing from step Ss onwards.

On the other hand, if the dial tone signal matches the polling code, a message is sent in step Ss to the effect that a PIN code (such as an IO number [device registration number] or PIN code) should be dialed to start the polling operation. sent to the station.

Next, in step S7, it is determined whether or not a dial tone signal has been sent from the calling station within a predetermined time. If the dial tone signal is not received, the telephone line is connected to the device in step Sm without performing the processes from step 88 onwards. be freed from. Further, when a dial tone signal is sent in step S7, in step S8 it is checked whether or not this dial tone signal matches the dial tone as a PIN code stored in the storage unit 5. It is determined whether the dial tone and the dial tone signal match or whether the dial tone is included in the dial tone signal.

If the dial tone signal does not match the password code, the telephone line is released from the device without performing the polling operation in step S8.

On the other hand, when the dial tone signal matches the pin code,
The polling operation is started in step S9, and when the polling operation is finished thereafter, the telephone line is released from the device by the network control unit 1 in step S5Ill.

As described above, in the present invention, since the PIN code for starting the polling operation is formed by the dial tone signal, the polling operation can be started by the dial tone signal from the originating station even if the originating station is a different manufacturer. Can be done.

Furthermore, in the above embodiment, when a dial tone signal other than a polling code is sent in step $5, the telephone line is opened from this device. A code for activating a function may be set in advance, and when it is determined in step S5 that the code is compatible, the function corresponding to the code may be activated.

Furthermore, although the message was sent to the calling station in step S3, when the telephone line was connected in step S2, the message sending in step S3 was omitted and a determination was made as to whether or not a dial tone signal was sent in step S4. You may also do so.

Further, the dial tone as the polling code or password code stored in the storage unit 5 may be one dial tone or may be a plurality of dial tones.

(Effects of the Invention) In the present invention, the polling operation is performed based on the dial tone signal from the originating station, so even if the originating station is of a different manufacturer, the originating station can instruct the polling operation using the dial tone signal. In addition, the polling operation is not performed when the dial tone signal from the calling station does not match the preset and stored dial tone, thereby preventing the polling operation from being performed due to a wrong call, etc. be able to.
