Description

Description: TECHNICAL FIELD The present invention relates to a data communication method for transmitting data by adding time information to the data.

[Related Art] Generally, a header displaying management information is added to the head of an image received by a facsimile machine. That is, the header includes information such as the destination number of the transmission source, the abbreviation, the number of pages, and the communication time.

The G4 facsimile apparatus based on CCITT creates a header on the receiving side, whereas the G3 facsimile apparatus creates a header on the transmitting side and transmits it as a part of an image.

[Problems to be Solved by the Invention] However, in the above-described G3 facsimile apparatus, when transmitting an image to an area having a time difference, such as overseas, since the date and time attached to the header are those of the transmission source. , And the date and time on the receiving side. Therefore, when trying to manage received documents and images by date and time, if the destinations of each document are diverse, the disadvantage is that the actual receiving order cannot be easily determined from the time in the header and is very confusing. there were. Further, when a received document is received later, it is necessary to recalculate how many hours before the received document arrived in consideration of a time difference, which is troublesome.

Also, for example, there are times when there is a time difference between cities in a country like the United States, and the reliability of time information cannot be improved considering the time difference on the receiving side without taking this into account. Come up.

On the other hand, if the time difference information is made to correspond to all the cities in the world, the number becomes huge, and the cost for that becomes high.

The present invention has been made in view of the above points, and data to be transmitted includes time information in consideration of a time difference in a destination country and a region included in this country or time information based on the current time of a transmission instruction source according to a situation. It is an object of the present invention to provide a data communication method that can be additionally transmitted.

[Means for Solving the Problems] The present invention provides a registration step of pre-registering a destination country and a region included in this country in association with time difference information, an instruction step of instructing data transmission, An identification step of identifying a destination country and a region included in the destination based on the instruction in the process; and determining whether the destination country and the region included in the country based on the instruction in the instruction process are registered in the registration process. A determining step, a calculating step of calculating a time difference between a current time of an instruction source in the instruction step and a destination based on the identification result in the identification step, and time information obtained in the arithmetic step according to the instruction of the instruction step. A transmitting step of adding to the data and transmitting the data, wherein in the transmitting step, the destination country based on the instruction in the instruction step and the status included in this country are registered in the determining step. When it is determined that there is no destination, the data is transmitted with the current time of the instruction source added without adding the time information according to the destination.

Embodiment FIG. 1 is a block diagram showing an embodiment of the present invention.

The facsimile apparatus includes a central control section 1 for controlling the entire apparatus, a memory management section 2 including a ROM and a RAM,
A communication control unit 3 for exchanging data with a partner terminal through a communication line 20, an operation unit 4 provided with various keys, an LCD display unit 5 for performing various displays, and a time management unit 11 having a clock function
And an image reading unit 12 for reading a document.

The operation unit 4 includes a stop key 6, a start key 7, a set key 8, a registration key 9, and a numeric keypad 10.

FIG. 2 is a flowchart for explaining an operation of registering a time zone area number sequence in this embodiment.

Here, as an example, a case where a local code of Los Angeles is registered will be described.

When performing this registration, the user first presses the registration key 9 on the operation panel 4. The central control unit 1 always performs key sensing (S31), but when confirming that the registration key 9 has been pressed (S32), the display of the LCD display unit 5 changes the display for area number registration as shown in FIG. The display is switched (S34), the registration mode is entered, and the state returns to the key sense state (S35). If the registration key 9 is not pressed, other processing is performed (S33).

Next, the user uses the numeric keypad 10 to input a number sequence to be registered as an area code. When entering Los Angeles, international TEL (= 001) + international identification number (US = 1)
+ Los Angeles area code (= 213) = 0011213.

When the set key 8 is pressed (S36), the display is
The display is switched to the time difference registration display shown in FIG. 4 (S37),
Enter the time difference and return to the key sense state (S3
8).

Here, the user inputs the time difference to be registered in the form of “+/− how many hours”. Los Angeles is 16 hours behind Tokyo, so enter "-16". Then, the set key 8 is pressed (S39).

As a result, the display on the LCD display unit 5 is switched again,
The display for abbreviation input as shown in FIG. 5 is displayed (S40).
Therefore, the user inputs an abbreviation using the ten keys (or touch keys), and presses the set key when this is completed (S42).

As a result, the central control unit 1 registers the input items in the time difference area number table in the memory management unit 2 (S4).
3) Switch the display and return to the standby state (S44).

FIG. 6 is a flow chart for explaining the transmission operation in the facsimile machine.

Here, as an example, a case where facsimile transmission is performed from Tokyo at 9:00 am will be described.

First, in the key sense state (S51), when the user sets a document on the original and presses the start key 7 (S52), the central control unit 1 sends the number sequence registered in the time zone table of the memory management unit 2 to the transmission destination. It is checked whether it matches the number sequence at the head of (S54, S55).

Then, when the start number of the transmission destination does not match any of the registered number strings, as shown in FIG.
At 9:00 am Tokyo time, a header is created (S60) and added to the transmission image and transmitted (S58).

If there is a matching number sequence, the local time is calculated with reference to the registered time difference (S56).

As mentioned above, Los Angeles is registered as having a time difference of -16 hours, and the current time in Tokyo is 9:00 am, so in Los Angeles it is 5:00 pm the day before.

The time management unit 11 calculates the local time and sends it to the communication control unit 3. At this time, if an abbreviation is registered, it is also sent to the communication control unit 3.

The communication control unit 3 creates a header as shown in FIG. 8 from the received local time and abbreviation (S57).
By giving the abbreviation after the communication time of the header in this way, the receiving side can know what the printed time is.

When the header is created, the communication control unit 3 attaches the header to the top of the transmission image and starts transmission (S5).
8).

As described above, by setting the date and time included in the header attached to the transmission image to the local time of the transmission destination,
The receiving side can know at a glance when the facsimile has been received at other times of reception.

Regarding received documents, documents received by any G4 / G3 facsimile can be easily managed by date and time. Furthermore, since the present invention can be implemented by adding software, the manufacturing cost does not increase.

[Effects of the Invention] As described above, according to the present invention, when a destination country and an area included in this country are registered when transmitting data, the time taking into account the time difference of this area is considered. On the other hand, if the information is not registered, the information is transmitted with the current time of the transmission instruction source added, so that the data can be transmitted with the appropriate time information added according to the situation.
