DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus for performing a receiving process for reducing a receiving time.

[0002]

2. Description of the Related Art A facsimile apparatus generally has a function called one-touch dialing or abbreviated dialing in order to save the trouble of inputting all the identification information (telephone number, e-mail address) of a transmission / reception destination. Have.
One-touch dialing automatically registers the identification information of a specific destination in each of several buttons, and automatically connects to the destination registered in that button only by pressing one button. Function. Also,
The abbreviated dialing is a function of preliminarily registering identification information of a specific destination in each of a two-digit or three-digit number, for example, a function of substituting a telephone number of about ten digits with a two- or three-digit number. It is.

FIG. 5 is a flowchart showing a procedure of a process performed by a conventional facsimile apparatus when receiving image data. The facsimile machine is an ITU (International Telecommunication Union)
-T Recommendation T. It operates according to the procedures of 30 standard communication standards, and has a high resolution (1200 dpi × 1200 dpi, 60 dpi).
0 dpi x 600 dpi) and low resolution (400 dpi x
400 dpi, 200 dpi × 200 dpi).

[0004] The facsimile apparatus determines whether or not a call signal from the facsimile apparatus on the transmitting side has arrived, and if not, continues to wait for a call signal (S51). When a call signal arrives, facsimile operation (reception processing)
Start and receivable resolution (high and low resolution)
Is output to the transmitting side (S52).
At this time, the transmitting side specifies the resolution of the image data to be transmitted within the range of the resolution declared by the receiving side.

[0005] The telephone number (TSI signal) of the transmitting side sent from the transmitting side is received (S53). A signal (DCS signal) specifying the resolution sent from the transmitting side is received (S57). The CFR signal declaring the reception preparation confirmation is output to the transmission side, and the image data transmitted from the transmission side is received at the resolution specified by the transmission side (S58).

It is determined whether the reception of the image data has been completed (S59). If the reception has not been completed (NO in S59), the reception processing is continued, and if the reception has been completed (S5).
In the case of (YES in 9), the facsimile operation (reception processing) is completed, and the process returns to S51 to continue waiting for a call signal from the transmission side.

According to the conventional facsimile apparatus, the receiving side declares receivable resolutions (for example, high resolution and low resolution), and among the resolutions, the transmitting side has one of the common resolutions with the receiving side. The image data is transmitted by designating the highest resolution (for example, high resolution), and the receiving side receives the transmitted image data at the resolution (high resolution designated by the transmitting side). For this reason, even if it is known in advance that the image data to be transmitted is image data (for example, a document or direct mail) that can be received at a low resolution, it is necessary to specify a low resolution on the receiving side. Can not.

[0008] The high-resolution image data has a larger data amount than the low-resolution image data, and the reception time is longer.
By receiving image data that can be received at a low resolution at a high resolution, the facsimile machine cannot easily receive other necessary image data, and there is a problem that reception efficiency is deteriorated. .

In order to solve such a problem, Japanese Patent Laid-Open No.
In JP-A-149267, the telephone number of the transmitting side that transmits image data (for example, drawings) that need to be received at a high resolution is registered in advance in abbreviated dialing, and the telephone number of the transmitting side is registered before the facsimile operation starts. Receive, if the phone number is registered in speed dial, declare all receivable resolutions including high resolution, otherwise declare low resolution concealing the ability of receivable resolution Facsimile machines have been proposed.

The transmitting side specifies the resolution of image data to be transmitted within the range of the resolution declared by the receiving side. Therefore, according to the facsimile apparatus, image data transmitted from the transmitting side not registered in the speed dial is transmitted. The image data can be received at a low resolution, the image data can be efficiently received, and the reception time can be reduced.

[0011]

However, it is not always necessary for all transmission sides registered in the speed dial to receive at high resolution, and the transmission side registered in speed dial receives at low resolution. Also, when image data is transmitted, the image data is received at a high resolution, which causes a problem that the reception time becomes long.

The present invention has been made in order to solve such a problem, and includes identification information of a transmitting side (for example, a telephone number).
And the resolution (for example, high resolution or low resolution) corresponding to the type or necessity of the image data transmitted from the transmitting side is registered in advance, so that the image data is transmitted from all registered transmitting sides. Without receiving the image data at a high resolution, for example, only the image data at the transmitting side that needs to be received at a high resolution at a high resolution, or the image data at the transmitting side that does not need to be received at a high resolution at a low resolution It is an object of the present invention to provide a facsimile apparatus capable of receiving image data efficiently, efficiently receiving image data, and shortening the reception time.

Another object of the present invention is to provide a method of receiving identification information of a transmitting side after starting a facsimile operation, firstly, when receiving a calling signal from the transmitting side, declaring a low resolution, When the identification signal is received and the identification information is registered, and the registered resolution is higher than the low resolution, by declaring the resolution again, all registered transmission sides Without receiving the transmitted image data at high resolution, for example, only the transmitting side image data that needs to be received at high resolution at high resolution, or the transmitting side image data that does not need to be received at high resolution Because each can be received at low resolution,
It is an object of the present invention to provide a facsimile apparatus capable of efficiently receiving image data and shortening a reception time.

Another object of the present invention is to first declare a low resolution, then receive an identification signal of the transmitting side, and if the identification information is not registered, send a reception preparation confirmation signal to the transmitting side. The present invention provides a facsimile apparatus capable of receiving image data of a transmission side that has not been registered at a low resolution by outputting the image data at a low resolution, thereby efficiently receiving the image data and shortening the reception time. .

Another object of the present invention is to first declare a low resolution, and then receive an identification signal on the transmitting side, and the identification information is registered. Is lower than or equal to the low resolution, by outputting a reception preparation confirmation signal to the transmitting side, it is possible to receive, at a low resolution, image data of the transmitting side that is previously determined not to need to be received at a high resolution. Therefore, it is an object of the present invention to provide a facsimile apparatus that can efficiently receive image data and reduce a reception time.

FIG. 3 is a flow chart showing a procedure of processing when the facsimile apparatus according to the present invention receives image data.

The facsimile apparatus determines whether or not a call signal has been received from the facsimile apparatus on the transmitting side, and if not, continues to wait for a call signal (S31). When a call signal arrives, facsimile operation (reception processing)
Is started, and a DIS signal declaring a low resolution is output to the transmission side (S32). This declaration is a pseudo-statement in which the capability of the resolution that can be received is falsely performed. At this time,
The transmitting side specifies the resolution of the image data to be transmitted within the range of the resolution declared by the receiving side.

The transmission side telephone number (TSI signal) sent from the transmission side is received (S33). It is determined whether the telephone number is registered in the one-touch dial table 6a (S34).

When the telephone number is registered (S3
It is checked whether or not the registered resolution exceeds the low resolution (S35). If the registered resolution exceeds the low resolution (YES in S35), a DIS declaring the registered resolution (high resolution)
The signal is output to the transmitting side (S36). At this time, the transmitting side specifies the resolution of the image data to be transmitted within the range of the resolution declared by the receiving side.

When the telephone number is not registered (S
If the resolution is lower than the low resolution (NO in S35), the low resolution is declared in S32. Also at this time, the transmitting side specifies the resolution of the image data to be transmitted within the range of the resolution declared by the receiving side.

A signal (DCS signal) designating the resolution sent from the transmitting side is received (S37). The CFR signal declaring the reception preparation confirmation is output to the transmission side, and the image data transmitted from the transmission side is received at the resolution designated by the transmission side (S38). It is determined whether the reception of the image data has been completed (S39). If the reception has not been completed (NO), the reception processing is continued. If the reception has been completed (YES), the facsimile operation (reception processing) is completed and the process returns to S31 to wait for a call signal from the transmission side. to continue.

In the facsimile apparatus of the present invention, for example, if the transmitting side refuses to publish the telephone number and the telephone number is not received, it may be determined that the telephone number is not registered (NO in S34). Equivalent). If the registered resolution exceeds the low resolution (S3
5, YES), instead of declaring the registered resolution (high resolution), declare all of the originally receivable resolutions (low resolution and high resolution), and convert the image data at the resolution specified by the transmitting side from among them. You may receive it.

FIG. 4 is an explanatory diagram of a communication protocol of the facsimile apparatus according to the present invention. Here, a case where the telephone number of the transmitting side is registered in the one-touch dial table 6a and the registered resolution is a high resolution will be described.

The transmitting-side facsimile apparatus outputs CNG to the receiving-side facsimile apparatus to indicate that the transmitting side is a non-voice terminal (call signal). The receiving side that has received CNG outputs CED to indicate that the receiving side is a non-voice terminal (response signal).

The receiving side outputs DIS to declare the receiving capability within the range of the T series recommendation. At this time, the receiving side declares a low resolution. Also, it outputs NSF and CSI, declares the receiving capability outside the range of the T series recommendation, and specifies the telephone number of the transmitting side. The transmitting side outputs DCS and designates a receiving capability within the range of the T series recommendation. At this time, the transmitting side specifies the low resolution. NS
S and TSI are output to designate a receiving capability outside the range of the T series recommendation and to indicate the telephone number of the transmitting side. The transmitting side performs training and outputs a TCF to check the result of training.

Since the telephone number is registered in the one-touch dial table 6a and the registered resolution is a high resolution, the receiving side outputs DIS again to declare the high resolution. Also, NSF and CSI are output again. The transmitting side outputs DCS again and specifies the high resolution. Also, NSS and TSI are output again. The transmitting side performs training and outputs TCF to confirm the result of training.

The receiving side outputs a CFR signal to declare reception preparation confirmation. The transmitting side transmits the image data to the receiving side. When the transmission of the image data is completed, the transmitting side performs
Outputs P to declare the end of the transmission procedure, the receiving side outputs MCF to declare message confirmation, and the transmitting side outputs DCN to instruct the line disconnection.

According to the facsimile apparatus of the present invention described in detail above, when the receiving side has a plurality of resolutions including a high resolution and a low resolution, the receiving side declares the low resolution in advance, so that the telephone number of the transmitting side can be changed. If it is not registered, or if the phone number is registered and the declared resolution lower than the low resolution is registered, even if the transmitting side desires to transmit the image data at a high resolution, Since the transmitting side must specify the resolution within the range of the resolution declared by the receiving side, the transmitting side specifies the low resolution, and after the transmitting side specifies the low resolution, the receiving side outputs a reception preparation confirmation signal. Then, the transmitting side transmits the image data at the low resolution.

As a result, image data on the transmission side which does not need to be received at high resolution can be received at low resolution.
It is possible to efficiently receive image data and shorten the reception time.

When a telephone number is registered and a resolution exceeding the declared low resolution, that is, a high resolution is registered, the receiving side has previously declared a low resolution. Since the other party does not transmit image data until the reception preparation confirmation signal output by the reception side is sent, the reception side declares the high resolution again, and after the transmission side specifies the high resolution, the reception preparation confirmation signal is transmitted. By outputting, the transmitting side can transmit the image data at a high resolution.

Therefore, only the image data on the transmission side which needs to be received at a high resolution can be received at a high resolution.

The facsimile apparatus of the present invention performs the above-mentioned communication according to ITU-T Recommendation T.30. 30 non-standard procedures can also be performed. In addition, the one-touch dial may be provided with a registration unit for registering a destination that performs both transmission and reception, and registering identification information and resolution of the destination that performs only reception, separately from the one-touch dial. In addition, a speed dial may be used to register a telephone number.

When acquiring the identification information of the transmission side,
The numbers display may be used to receive the telephone number prior to the start of the facsimile operation. Also, instead of telephone numbers, ISDN (Integrated Services Digital Network)
By receiving the source address before the start of the facsimile operation by using, the identification information of the transmission side can be obtained.

Further, a timer is installed in the facsimile apparatus of the present invention, and during a time period when the number of transmissions is small (for example, at night), all the facsimile apparatuses on the transmission side or all the transmission sides on which telephone numbers are registered are registered. All the receivable resolutions may be declared to the facsimile as before.

[0054]

According to the facsimile apparatus of the present invention, the identification information (for example, telephone number) of the transmitting side and the resolution (for example, high resolution or low resolution) corresponding to the type or necessity of the image data transmitted from the transmitting side. Resolution) is registered in advance, so that the image data transmitted from all the registered transmission sides is not received at a high resolution, but only the image data of the transmission side that needs to be received at a high resolution, for example. Can be received at a low resolution, or image data on the transmission side that does not need to be received at a high resolution.

Further, when receiving the identification information of the transmitting side after the start of the facsimile operation, when receiving the calling signal from the transmitting side, firstly, a low resolution is declared, and then the identification signal of the transmitting side is received, and the identification is received. If the information is registered,
When the registered resolution is higher than the low resolution, by re-declaring the resolution, the image data transmitted from all the registered transmission sides is received at the high resolution without receiving the high resolution, for example. Only the sender's image data that needs to be transmitted at high resolution, or the sender's image data that does not need to be received at high resolution, at lower resolution,
Each can be received.

Also, first, a low resolution is declared, and then, when the identification signal of the transmitting side is received and the identification information is not registered, the reception preparation confirmation signal is output to the transmitting side to register the identification signal. It is possible to receive the image data of the transmitting side that has not been transmitted at low resolution.

When the low resolution is first declared, and then the identification signal on the transmitting side is received and the identification information is registered, and the registered resolution is lower than the low resolution, By outputting a reception preparation confirmation signal to the transmission side, it is possible to receive image data of the transmission side which is known in advance not to need to be received at a high resolution at a low resolution, so that image data can be efficiently received. However, the present invention has excellent effects such as shortening the reception time.
