Description

Description: TECHNICAL FIELD The present invention relates to a facsimile apparatus, and more particularly, to a facsimile apparatus provided with a communication means.

2. Description of the Related Art Conventionally, there is a facsimile apparatus that includes a communication unit such as a speaker, a microphone, and a communication circuit and can perform a communication via a line.

In such a conventional facsimile apparatus, for example, in a facsimile apparatus accommodating two lines, when a facsimile reception is performed on the other line while talking on one line, both lines are used. Then, the telephone call and the facsimile reception are performed at the same time, and the received image data is recorded on the recording paper by the plotter. Also, even in a facsimile apparatus that accommodates only one line, if an image memory is provided, all received image data may be temporarily stored in the image memory and then recorded by a plotter. You can make a call using the line.

(Problems to be Solved by the Invention) However, such a conventional facsimile apparatus has a configuration in which a recording operation is performed by a plotter even during a call, so that noise accompanying the recording operation is mixed in a call signal. However, there was a problem that a comfortable call could not be made.

(Object of the Invention) Accordingly, the present invention prevents the noise associated with the recording operation from being mixed into the call signal by storing the received image data in the image memory during the call and prohibiting the recording operation. Then, it is intended to provide a comfortable device free from noise of a call.

(Constitution of the Invention) In order to achieve the above object, the present invention provides a scanner for reading an image of a document, a plotter for recording and outputting received image data on recording paper, and a communication means for making a voice call via a line, A facsimile device comprising: an image memory for storing image data, wherein during a call by the calling means, received image data is stored in the image memory, and recording and output operations by the plotter are prohibited. Is what you do.

 Hereinafter, a specific description will be given based on examples of the present invention.

1 to 4 are views showing one embodiment of the present invention.
This is applied to a facsimile apparatus accommodating two lines.

FIG. 1 is a block diagram of the facsimile apparatus 1. The facsimile apparatus 1 includes a network control unit 2, a communication circuit 3, a speaker 4, a microphone 5, a system control unit 6, a modem 7, a scanner 8, a plotter 9, and an image memory 10. Etc. are provided.

2 lines of the network control unit 2 calls dedicated line L ₁ and the facsimile dedicated line L ₂ is connected, the network control unit 2, the setting of a call, connection of line, performs control of the line, the second Each line L ₁ , L ₂ is provided with a paging signal detection circuit 21 as shown in FIG.
Detects a calling signal.

Is output to the system control unit 6. Speech circuit 3 amplifies the audio signal from the call-only line L ₁ and outputted to the speaker 4,
In addition, the audio signal from the microphone 5 is amplified to make a dedicated call
Send to L _1. The speaker 4 loudspeaks the voice signal outside the facsimile apparatus 1 as a voice, and the microphone 5 converts the voice uttered by the operator into a voice signal and outputs the voice signal to the communication line 3.
These speech circuit 3, the speaker 4 and the microphone 5 constitute a call unit 30 for performing communication by voice via a call-only line L ₁ as a whole.

The system control unit 6 includes a CPU (Central Processing Uniform).

The modem 7 modulates a transmission signal and demodulates a reception signal in facsimile communication. As the scanner 8, for example, a CCD (Charge Coupled Device)
A line image sensor using a
A document is read for each line and output as image data. As the plotter 9, for example, a Samar recording apparatus having a Samar element is used, and the plotter 9 performs recording while transporting the recording paper by a driving mechanism. Image memory
Reference numeral 10 denotes a storage capacity for storing image data for a plurality of pages. The storage unit 10 stores image data received at the time of memory reception or at the time of call recording inhibition processing of the present invention. Store data.

 Next, the operation will be described.

The present invention has its feature in place of prohibiting recording the output of the busy, if in the present embodiment, there is a call through the call-only lines L _1, even if received via a facsimile dedicated line L ₂ The image data is stored in the image memory 10 without recording and outputting. Hereinafter, the call recording inhibition process will be described with reference to the flowchart shown in FIG.

Facsimile apparatus 1, when the call-only line L ₁ or facsimile dedicated line L ₂ is ringing signal RS, is detected by the call signal detection circuit 21 of the network control unit 2, and outputs a detection signal OS to the system control unit 6. The system control unit 6 detects the detection signal OS
Upon receiving the instructs the閉結of the line with the network control unit 2 of the call signal RS, make a call or facsimile communication by the facsimile dedicated line L ₂ by calling dedicated line L _1.

In the call recording prohibition process, the system control unit 6
First, from the facsimile dedicated line L ₂ checks whether the incoming calling signal RS (step P _1), when there is a call signal RS from the facsimile dedicated line L _2, the image data by performing a normal facsimile reception procedure Start receiving.
The received image data is stored in the image memory 10, and
When the image data of the page is stored in the image memory 10 (step P _2), call-only lines L ₁ to check whether or not used (step P _3). If call-only line L ₁ is not in use, to transfer the image data of one page stored in the image memory 10 to the plotter 9 recorded output to the recording paper (Step P _4), the one page recording is completed Then, the image memory 10
Whether there are any remaining image data on the following pages to check within (step P _5). When the image data remains in the image memory 10, the process returns to step P _3, to check call-only line L ₁ whether in use, if not in use call-only lines L _1, similarly next page Is transferred to the plotter and recorded and output (steps P ₃ and P ₄ ). If the image data is not in the image memory 10, and checks whether the facsimile communication is terminated (Step P _5), if not finished, the image memory 10 the image data received by facsimile reception returns to the step P ₂ To accumulate. Images accumulated image data in the memory 10 to check whether during Similarly call-only line L ₁ is used, call-only line L ₁ records output if not in use (Step P _3, P _4).

On the other hand, in Step P _3, when call-only line L ₁ is in use, it prohibits recording output, and facsimile reception and stores the received image data in the image memory 10 (step P _6,
P _2, P _3). When the call is terminated during facsimile reception (steps P ₆ , P ₂ , P ₃ ), the image data in the image memory is transferred to the plotter 9 for recording and output (steps P ₄ , P ₅ ,
P ₆ ). If end call facsimile reception during call-only line L ₁ (step P _6), and checks whether a call call-only line L ₁ of the image data in the image memory 10 to finish (step P _7, P ₃₎ When the call call-only line L ₁ is completed, to transfer the image data in the image memory 10 to the plotter 9 to record output (step P _3, P _4). Image memory 10
When recording the output of all image data of the inner is completed (step P _7), the flow is terminated.

In this way, there is a facsimile reception during a call,
When a call is started during facsimile reception, image data recording and output can be prohibited and the image data can be stored in the image memory. Therefore, it is possible to prevent the noise of the recording output from being mixed into the call signal, and it is possible to comfortably perform the call.

In the above embodiment, the case where two lines are accommodated and one is dedicated to a call and the other is dedicated to a facsimile has been described. However, the present invention is not limited to this, and the number of lines may be one, or three or more. It may be. Further, in the above embodiment, the image data is managed for each page, and the presence or absence of a call is checked. However, the present invention is not limited to this.

(Effects) According to the present invention, it is possible to prevent noise associated with the recording operation from being mixed into the call signal, and to make the call comfortable and free of noise.
