Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an automatic reception canceling device for a facsimile machine which allows a facsimile machine set to an automatic reception state to be canceled by making a call from an ordinary telephone.

[Technical background of the invention]

Conventionally, when making a call to a facsimile that is set to automatic reception mode, the calling side sends a special signal (call request signal) to the receiving facsimile, and when the receiving facsimile detects reception of this call request signal, it emits a buzzer, etc. When an operator heard the buzzer or other sound, he or she would manually switch the line to the telephone and make a call.

[Problems with background technology]

However, with such conventional devices, calls can only be made to a facsimile set to an automatic receiving state from a device capable of generating the above-mentioned special call request signal, that is, from a facsimile equipped with such a function. For example, even if I wanted to make a call from a public telephone or the like through a facsimile telephone that was set to receive automatically, I was unable to do so.

Therefore, a facsimile machine is being considered in which the received signal is output through a speaker, and if the received signal is voice, the operator detects this and cancels the automatic reception state. In this reception state, the facsimile image signal would be emitted from the speaker as noise, making it impractical for practical use.

[Purpose of invention]

This idea was made in view of the above points, and it is a facsimile machine that allows calls to be made from any telephone when the facsimile machine is set to receive automatically, and also does not generate unnecessary noise. The purpose of the present invention is to provide an automatic reception cancellation device.

[Summary of the idea]

In order to achieve this object, the present invention provides a signal determination circuit that determines whether or not a received signal is a facsimile signal, and starts a timing operation upon arrival of the received signal, and the signal determination circuit determines whether or not the received signal is a facsimile signal. A timer circuit is provided which resets the timing operation when it is determined that the signal is a facsimile signal, and the notification means is activated when the predetermined timing operation of the timer circuit ends, whereby the facsimile signal is transmitted to the speaker. This eliminates the inconvenience of the facsimile being pronounced as noise through the telephone, and also enables the operator to cancel the automatic facsimile reception state based on the notification from the notification means. According to this configuration, it is possible to cancel the automatic reception state of a facsimile without generating a special signal on the calling side, so that a call can be made from an ordinary telephone to a facsimile that is in the automatic reception state.

[Example of idea]

An embodiment of this invention will be described in detail below.

The figure shows an embodiment of the facsimile automatic reception cancellation device of this invention.

In the figure, 1 is a facsimile device, 2 is a telephone installed in the facsimile device, 3 is a calling side telephone, and 13 is a calling side telephone 3 and the facsimile device 1.
Shows the public telephone line connected to the

If the caller uses the telephone 3 to dial the called party's facsimile device 1, which is set to automatic reception mode, the telephone 2 will first ring, and at the same time, the 16Hz detection circuit 4 will send a 16Hz ringing signal. The output of the 16Hz detection circuit 4 activates the switch 5 and switches the line 13 from the telephone 2 to the amplifier 6. After dialing the called party, the calling party repeats "Moshimoshi...", so the voice signal is applied to the amplifier 6 via the switch 5 and amplified. The output of this amplifier 6 is applied to a signal detection circuit 7 to detect the arrival of the signal, thereby starting the timer 12 to measure time. Simultaneously with this operation, the detection circuit 8 detects the incoming signal output from the amplifier 6 and applies this detected signal to the signal determination circuit 9. The signal determination circuit 9 determines whether the incoming signal is a facsimile image signal based on the output of the detection circuit 8. Here, if it is determined that the incoming signal is a facsimile image signal, the timer 12 is reset by the output of the signal determining circuit 9. Further, the recording circuit 15 records the detected signal. However, if the incoming signal is audio, the timer 12 is not reset and therefore outputs a signal after a predetermined time T has elapsed, and this signal causes the switch 10 to switch to connect the speaker 11 to the output of the amplifier 6. As a result, the voice from the caller is emitted from the speaker 11, and the called party hears the voice amplified through the speaker 11, for example, "Moshi-moshi...", determines that it is a call request, and uses the reset switch 14. The switch 5 is operated to switch the line 13 to the telephone 2 again.

In this way, it is possible to dial a facsimile set for automatic reception from a telephone as usual, cancel automatic reception by voice, and make a call.
Furthermore, since the timer 12 is used, even if the incoming signal is a facsimile signal, it will be emitted from the speaker and there will be no problem of noise. Note that the timer time T of the timer 12 is preferably set to about 2 seconds, for example. This is sufficient to determine whether the incoming signal is a facsimile image signal or not, and in the case of voice, the first "moshi, mo" is missing, making it possible to communicate without causing any unnaturalness to the caller. You can start.

[Effect of idea]

As explained above, according to this invention, since the automatic reception state of a facsimile is canceled using voice reception, the telephone equipped with a facsimile that is in an automatic reception state can be used even from a normal telephone such as a public telephone. This has the advantage that it is possible to start a call using the line, and the line can be used effectively. Further, unnecessary noise does not occur on the receiving side.
