Abstract

PURPOSE:To shorten the time for the exchanges of facsimile signals for determining the transmission speed at the time of the transmission by the dial stored in a facsimile equipment. CONSTITUTION:A control means 9 performs the processing to retrieve and determine transmission speed. Namely, when a transmission processing is performed utilizing registered telephone number information, the transmission speed by which an image communication is surely possible is determined by starting from the transmission speed of the previous dial when the first facsimile signal is transmitted and received and by repeating the transmission and reception of the facsimile signal, changing the transmission speed, and the determined transmission speed information is made to be stored in a storage means 10. Subsequently, when the transmission processing of the same telephone number is performed, the transmission speed information corresponding to the telephone number is used by reading it from the storage means 10. Therefore, the useless exchanges of facsimile signals is decreased by storing the previous transmission speed information and utilizing it.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine for transmitting and receiving images and documents.

[0002]

2. Description of the Related Art Conventionally, when an image or document is transmitted by a facsimile machine, a training signal, a reception preparation confirmation signal (hereinafter CFR) and a training failure signal (hereinafter referred to as "training failure signal") are used to determine the transmission speed before transmitting the image signal. FTT)
The communication speed determines the transmission speed (fallback function) and determines the transmission speed.

This operation is always performed regardless of normal dial operation or one-touch dial. The operation of the facsimile apparatus configured as described above will be described below.

FIG. 3 is a block diagram showing the structure of a conventional facsimile apparatus, and FIG. 4 is a flow chart showing its operation.

Reference numeral 1 is a telephone line, 2 is an interface circuit with the telephone line 1, 3 is a dial means for sending a dial signal to the telephone line 1, 4 is a storage means for storing a telephone number, and 5 is a facsimile for the telephone line 1. Facsimile signal transmitting means for transmitting a signal, 6 is a facsimile signal receiving means for receiving a facsimile signal input from the telephone line 1, 7 is a control means for controlling the apparatus, and 8 is a telephone number input means.

Regarding the transmission using the storage device of the facsimile apparatus including the above components, the mutual relation and operation of the components will be described below.

First, when a destination telephone number is input from the telephone number input means 8 by a registration operation, the control means 7 stores the telephone number in the storage means 4 in the order of input.

The control means 7 determines whether it is off-hook (step 1). The key reception process is performed without being off-hook, and as a result, it is determined whether the one-touch dial key is pressed. If the one-touch key is pressed, the control means 7 determines the presence or absence of paper (step 2).

The control means 7 judges whether or not it has already been registered in the storage means 4, and if it has already been registered, the control means 7 controls the interface circuit 2 by an operation of instructing the transmission of a document from an operation section (not shown) The telephone line 1 is closed (step 3).

Next, the dial means 3 and the memory means 4 are controlled so that the dial signal of the telephone number stored in the memory means 4 is generated by the dial means 3 and transmitted to the telephone line 1 via the interface circuit 2. (Step 4).

The control means 7 is a facsimile signal receiving means 6
As a result, the receiving side waits for the DIS signal according to the CCITT recommendation from the receiving side. When the DIS signal is received, the control means 7 sends a training signal for setting the communication speed from the facsimile signal transmission means 5 according to the CCITT recommendation (step 5).

The control means 7 is a facsimile signal receiving means 6
Further, the reception side waits for the CFR signal or the FTT signal according to the CCITT recommendation from the receiving side (step 6).

Upon receiving the FTT signal, the control means 7 lowers the speed of the training signal transmitted previously by one rank in order to set the communication speed again, and sends it out from the facsimile signal transmitting means 5 (step 7).

Upon receiving the CFR signal, the control means 7 determines the transmission rate (step 8). After that, the set document is read by the image reading means (not shown) and transmitted by the facsimile signal transmitting means 6 (step 1).
1).

After it is determined in step 1 that there is off-hook, the control means 7 controls the interface circuit 2 to close the telephone line 1 (step 9).

After that, when the key is received and the one-touch dial key is pressed, the dial means 3 and the storage means 4 are controlled so that the dial means 3 generates a dial signal of the telephone number stored in the storage means 4. , To the telephone line 1 via the interface circuit 2. After sending the dial, the key is accepted again, and when the fax transmission start key is accepted, the process proceeds to step 5 (step 10).

[0017]

However, in the above-mentioned configuration, the transmission speed is determined for each transmission even when the transmission speed is determined by one-touch dial, which is determined for each transmission. The training signal is started from the maximum speed, and the CFR (or FTT) is exchanged to determine. Therefore, there is a problem in that time is wasted before the transmission speed is determined.

The present invention has been made in view of the above-mentioned prior art, and provides a facsimile apparatus capable of eliminating waste of time until the transmission speed is determined when transmitting by one-touch dialing.

[0019]

To achieve this object, the facsimile apparatus of the present invention is provided with a training means for determining a transmission speed according to the stored contents by providing an area for storing the previous transmission speed in the storage means. It comprises control means for determining the start speed of the signal and transmitting it by the facsimile signal transmitting means.

[0020]

With this configuration, when transmitting with one-touch dial, the start speed of the training signal starts from the previous transmission speed, and the time until the transmission speed is determined is shortened.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a facsimile apparatus according to an embodiment of the present invention. FIG. 2 is a flowchart showing the operation.

In FIG. 1, 9 is a control means. The control means 9 has a configuration in which the control means 7 of the conventional example shown in FIG. 3 is provided with processing for searching / determining the transmission speed and processing for storing the determined transmission speed in the storage means. Reference numeral 10 denotes a storage means, which is a structure in which the storage means 10 of the conventional example shown in FIG. 3 is provided with an area for storing the transmission speeds of the previous time and the last time before and the registered telephone numbers. The other structure is the same as that of the conventional example shown in FIG.

The operation of the facsimile apparatus configured as described above will be described below. First, when inputting the destination telephone number from the telephone number input means 8 by the registration operation,
The control means 9 stores the telephone numbers in the storage means 10 in the order of input. At the same time, the transmission speed of the previous / previous transmission, which is set as a pair with the telephone number, is initialized to the maximum speed (start).

First, steps 1 to 4 and steps 9 and 10 in FIG. 2 are the same as those in the conventional example shown in FIG.

In the training signal determination processing, the control means 9 first confirms from the storage means 10 whether or not the transmission speeds of the previous time and the previous time are stored, and when they are not stored, the start speed of the training signal is determined to be the maximum speed ( Step A).

When it is confirmed in step A that the data has been stored, the control means 9 compares the transmission speeds of the previously transmitted dial and the transmission two times before the transmission (step B).

When the compared results are the same, the control means 9 sets the previous transmission speed stored in the storage means 10 as a candidate for the start speed of the training signal this time (step C).

The control means 9 confirms whether the candidate of the starting speed of the training signal is the lowest speed, and if the result is different, determines the candidate as the starting speed of the training signal (step D).

When the control means 9 determines that it is the lowest speed, it determines the starting speed of the training signal to be the highest speed for correction (step E).

If the result of comparison in step B is different, the control means 9 determines which of the transmission speeds stored in the storage means 10 is the faster speed as the start speed of the training signal (step F).

After the start speed determination process of the training signal is determined as described above, the same process is performed from steps 5 to 8 in FIG. 4 of the conventional example.

After the transmission speed is determined in step 8, the control means 9 stores the transmission speed of this time in the area for storing the transmission speed of the previous time which is paired with the dial transmitted this time of the storage means 10, The previous transmission speed is stored in the area for storing the transmission speed of the previous transmission (step 11).

The document set by the image reading means (not shown) is read and the facsimile signal transmitting means 6 transmits it (step 12).

The steps 11 and 12 can be interchanged. As described above, according to the present embodiment, the start speed of the training signal at the time of one-touch dialing is determined, so that the time until the transmission speed is determined can be shortened.

[0036]

As described above, the present invention shortens the time until the transmission speed is determined by storing the previous transmission speed of the one-touch dial and using it to determine the start speed of the training signal. It can do things, and its practical effects are great.
