Next, data transmission parameters when image data or character data is sent and received between the facsimile device 2 and the personal computer 4 or with another facsimile device (hereinafter referred to as a partner device). Setting of and processing of received data and the like will be described.

When facsimile data is transmitted and received between the facsimile device 2 and the partner device, transmission parameters such as transmission speed, resolution, paper width, coding method, and whether character data can be transmitted and received can be set. Done.
Each of these transmission parameters has a plurality of levels as will be described later, and the facsimile data is transmitted at the highest level of the levels common to the facsimile apparatus 2 and the partner apparatus. The same applies to the transmission and reception of data between the facsimile device 2 and the personal computer 4.

In the present embodiment, the transmission parameter level of the personal computer 4 is lower than that of the facsimile apparatus 2,
When data is transmitted to the partner device by the facsimile device 2, or when the facsimile data transmitted from the partner device is received by the personal computer 4, the level of the personal computer 4 is set to the level of the facsimile device 2, and the level is set to that level. Transmission parameters are determined based on the above.

First, the resolution will be described. However,
For simplification of explanation, the pixel size in the scanning direction is the same in both the facsimile device 2, the partner device and the personal computer 4, and only in the sub-scanning direction, as described above, 0.07 mm, 0.13 mm, Any of three steps of 0.26 mm, super fine, fine,
It shall correspond to the standard resolution.

When facsimile data is transmitted and received between the facsimile device 2 and the partner device regardless of the personal computer 4, the resolution of the facsimile device 2 is superfine as described above, and therefore If the highest resolution is also superfine, the resolution is determined to be superfine, and if the highest resolution of the partner device is fine, the resolution is determined to be fine.

The resolution of the personal computer 4 is the resolution for displaying an image on the display 116. This display 11
If 6 is composed of a liquid crystal having a size of {200 dpi (dots / inch) × 400 dpi}, this size corresponds to the size of one pixel in the super fine resolution of the facsimile apparatus 2. However, that does not mean that the resolution of the personal computer 4 is immediately determined to be superfine. The resolution of the personal computer 4 is generally fine. In the personal computer 4, the transmitted image data is made to correspond to the liquid crystal of the display device 116 by executing a predetermined program, and the program included in the personal computer 4 creates image data with a fine or standard resolution, Display 116
Is to be displayed on.

The facsimile apparatus 2 of the present embodiment has the highest resolution of super fine as described above, but since the highest resolution of most of the personal computers 4 is fine as described above, the facsimile apparatus 2 and the personal computer 4 are In between, the resolution is generally finely determined.

Therefore, when the facsimile device 2 sends the image data sent from the personal computer 4 to the partner device, the resolution is determined to be fine even if the partner device has a super fine resolution. In this case, the highest resolution of the facsimile apparatus 2 is fine, and the resolution is determined based on that.

In this way, when the resolution is determined between the two facsimile devices, in order to guarantee the reproducibility of the original image, the minimum reading unit of the image reading device 62 and the recording device 3 are used.
It may be necessary to process the image data according to the difference in the size of the dot formation point of 0 or the difference in the maximum resolution. Further, the image data may be required to be processed between the facsimile device 2 and the personal computer 4 due to the difference in the maximum resolution.

First, the case where the facsimile apparatus 2 receives the image data sent from the personal computer 4 and records the image data by the recording device 30 will be described.

In this case, the resolution is determined to be fine, and the facsimile device 2 receives the image data created in fine. When printing, each dot data is increased to two dot data in the scanning line direction, and one line data is increased to two line data in the sub scanning line direction.

Next, the case where the facsimile apparatus 2 receives the image data sent from the partner apparatus and sends the image data to the personal computer 4 will be described.

When the resolution between the facsimile device 2 and the partner device is set to superfine, the facsimile device 2 extracts line data in the sub-scanning line direction every other line and sends it to the personal computer 4. . If the resolution is set to fine with the partner device, data processing is unnecessary.

Further, when the image data read by the image reading device 62 of the facsimile apparatus 2 is sent to the personal computer 4, the resolution is set fine, so that the image data processing is unnecessary.

Even when the partner device or the personal computer 4 has only the standard resolution, the image data is processed similarly.

For example, if the resolution of the image data received by the facsimile device 2 from the partner device is super fine and the maximum resolution of the personal computer 4 is standard,
If the data of one line is extracted from the data of four lines in the sub-scanning line direction, and the resolution of the image data sent from the partner device is fine, the data of one line is extracted from the data of two lines.
The line data is extracted and sent to the personal computer 4.

When the fine resolution image data sent from the personal computer 4 to the facsimile device 2 is sent to the partner device having the highest standard resolution, one line of data is extracted from two lines of data. To be done.

The paper width will be described.

The maximum paper width in the facsimile device 2 is the maximum document width that can be read by the image reading device 62 and the maximum recording paper width that can be recorded by the recording device 30. In this embodiment, it is B4 size. is there. Also, the maximum paper width in the personal computer 4 including the scroll 11
6 is the maximum image width that can be displayed, and here is A4 size.

In both of the facsimile apparatus 2 and the partner apparatus and between the facsimile apparatus 2 and the personal computer 4, the sheet width is the same as the sheet width of the image data to be sent if it is smaller than the maximum sheet width on the receiving side. It is determined by the paper width of the image data to be sent out, and is determined as the maximum paper width if it is larger than the maximum paper width on the receiving side.

Therefore, when the paper width determined between the facsimile device 2 and the partner device is different from the paper width determined between the facsimile device 2 and the personal computer 4, or when the paper width is read by the image reading device 62. When the paper width of the original document and the paper width determined between the personal computer 4 are different, it is necessary to process the image data.

For example, when the image data received by the facsimile apparatus 2 is for B4 size and it is necessary to reduce the image data to A4 size image data,
Four pieces are extracted from the five dot data in the width direction (scanning direction) of the B4 size image data, and four line data are extracted from the five line data in the length direction (sub-scanning direction).

In the present embodiment, the processing of the image data required due to the difference in the sheet width and the difference in the resolution is collectively performed. The dot data extraction rate in the scanning direction and the sub-scanning direction is determined based on the data reduction rate due to the difference in the paper width and the data extraction rate due to the difference in the resolution.

In this embodiment, the paper width is different from (smaller than) the paper width of the image data to be sent only when the paper width of the image data to be sent is larger than the maximum paper width on the receiving side. Therefore, data increase processing for image enlargement is not performed. Further, regarding the resolution, in the recording device 30 of the facsimile device 2,
Although the dot data may be increased, it is not necessary to increase the dot data for data transmission because the resolution is determined to be the lower of the highest resolutions of the sender and receiver during data transmission. is there.

The encoding system will be described.

In the facsimile data transmission, digital data encoding methods include MMR (Modified MR) method and MR (Modified READ (Relative Element Address D).
esignate)) method and MH (Modified Huffman) method
There are several types, the MMR method is the most advanced coding method with the smallest number of data, and the MR method is the next most advanced coding method.

The coding system is also determined to be the highest coding system among the coding systems common to the transmitting side and the receiving side. If the facsimile device 2 sends the image data received from the partner device to the personal computer 4, or if the image data received from the personal computer 4 is sent to the partner device, if the coding systems of both devices are the same, the coding system Is not necessary, and the personal computer 4 sends the encoded data as it is through the facsimile apparatus 2. However, when the two encoding systems are different, the personal computer 4 converts the encoding system according to the encoding system of the other party and then transmits the data via the facsimile apparatus 2.

Transmission / reception of character data will be described.

In transmitting facsimile data, in order to transmit character data, a BFT (Binary File Tr
ansfer) method, and ITU Recommendation T. It is adopted in 30. According to this method, the BFT is set on both the transmitting side and the receiving side.
If the system is supported, the character data can be transmitted and received without being converted into image data. Therefore, the character data created by the personal computer 4 can be directly transmitted to the partner device via the facsimile device 2, and the transmission speed is generally improved as compared with the case of transmitting the image data. However, if the partner device does not have the ability to support the BFT system, the character data created by the personal computer 4 is once expanded into image data by the personal computer 4, and then encoded via the facsimile device 2 according to the encoding system of the partner device. It is converted and transmitted.

Similarly, the character data and the image data received from the partner device can be stored in the facsimile device 2 according to the setting of the facsimile device 2, or can be stored in the personal computer 4 via the facsimile device 2. You can also

After the preparation confirmation flag of the flag area 194 is turned on in step 6, the normal termination flag is turned off in step S207, and the execution of the routine ends. If the transfer destination dial number is not registered, S207 is directly executed and the routine is ended.

The dial routine of S9 will be described with reference to FIG.

In S301, it is determined whether or not the facsimile device 2 is on redial. If redial is not in progress, the dial number of the transfer destination is read from the dial memory area 190 in S302, and a call signal to the transfer destination is issued, and then it is determined in S303 whether or not the transfer destination has arrived. If the transfer destination has arrived, the execution of the routine ends, and if the transfer destination has not arrived, S304 is executed and the execution of the routine ends.

In S304, redial conditions are set. The redial flag of the flag area 194 is turned on, the line is opened, the number of redials is set to m, the redialing time interval is set to t minutes, and the timer that independently calculates the time Is acquired, the previously set time interval is added to that time, and the first redial time is set.

When the facsimile is being redialed in S301 and the determination is YES, the number of redials is reset to n = m + 1 in S305, and the execution of the routine ends.

The redial routine of S13 will be described with reference to FIG.

In S401, it is determined whether the time set for redialing has already passed. If the time has passed, the transfer destination is called in S402, and if the time has not passed, the execution of the routine ends.

The call of the transfer destination in S402 has the same procedure as the call of the transfer destination in the dial routine of S8, and after the dial number is read from the dial memory area 190, the transfer destination is dialed.

In the next step S403, it is determined whether or not the transfer destination has arrived. If the transfer destination has received an incoming call, the incoming call flag of the flag area 194 is turned on in S404, the redial flag is turned off in S405, and the execution of the routine ends. If the transfer destination has not arrived, S407 is executed after the number of redials is increased in S406.

At S407, it is determined whether or not the redial is completed after redialing the set number of times. If the redial is completed, the redial flag is set to O in S405.
If the execution of the routine is completed after the FF and the redial is not completed, the current time is acquired in S408,
The redial time interval t set by the dial routine of S8 is added to that time to set the next redial time, and the execution of the routine ends.

The transfer routine of S11 will be described with reference to FIG.

When the connection with the transfer destination facsimile machine is completed, the communication protocol procedure is executed in S501, and in this communication procedure, transmission speed, resolution, paper width, encoding method, and BFT method transmission / reception are possible. The transmission parameters are set. In particular, here, it is determined in S502 whether or not the transfer destination facsimile apparatus can receive the character data, that is, whether or not it has the BFT capability.

Here, the transfer destination facsimile machine is BF
If it has the capability of T, all the untransferred image data among the image data stored in the image data memory area 200 in S503 is converted into character data by using an OCR (optical character recognition device). It is stored in the character data memory area 202.

If the destination facsimile machine does not have the BFT capability in S502, all the untransferred character data among the character data stored in the character data memory area 202 in S504 are converted into image data. And stores it in the image data memory area 200.

At this time, the converted data is stored with a new management number next to the data stored in the data memory areas 200 and 202 in advance.

After that, in S505, the management number of the transmission identification code area 212 of the received data management memory area 186 to which the non-transmission identification code 1 is added is read into the management buffer memory area 192 and managed in the management buffer memory area 192. The B value, which is the index of the order in which the numbers are stored, is 0
After being set to S506, S506 is executed.

In S506, the management buffer memory area 1
The (B + 1) th management number of the management numbers sequentially stored in 92 is read, and in S507, the data of the data group corresponding to the read management number is transmitted in units of page, S508 is executed each time. In S508, it is determined whether or not the transmission is normally completed. If the transmission is normally executed, S509 is executed, and if the transmission is not normally executed, S511 is executed.

In S509, it is determined whether or not the transmission of the entire data group corresponding to the read management number is completed. If the transmission is completed, S510 is executed, and if the transmission is not completed, S507 is executed. Return to.

In S511, the codes of the transmission identification code area 212 are set before the data group corresponding to the management number currently being processed, that is, from the first read data group to the Bth read data group. When it is set to 0, the untransmitted state is released, and the management number stored in the management buffer memory area 192 is cleared. After that, S514 is executed, the line is released, and the execution of the routine ends.

In S510, the management buffer memory area 1
It is determined whether or not the data group corresponding to all the management numbers stored in 92 has been transmitted. If the data group corresponding to all the management numbers has been transmitted, S512 is executed,
If all the data groups corresponding to the management number have not been transmitted, S513 is executed.

In S512, the management buffer memory area 1
For the data group corresponding to all the management numbers stored in 92, the code in the transmission identification code area 212 is set to 0, the untransmitted state is released, and the management buffer memory area 1
All the management numbers stored in 92 are cleared. After that, S514 is executed, the line is released, and the execution of the routine ends.

In S513, B is read in order to read the next data group after the data group that has been read so far.
The value is increased. In this way, the management numbers are read one after another and the corresponding data groups are transferred sequentially.

Therefore, if the destination facsimile machine has the BFT system capability, the facsimile machine 2
Send all data as character data from
It is possible to edit the data received on the receiving side at a higher speed than that of transmitting image data using a personal computer.

Although the embodiment of the present invention has been described in detail above, the present invention is not limited to this embodiment.
For example, the image and character data stored in the image / character data memory area 184 are not necessarily the image data memory area 200 and the character data memory area 2
02 need not be stored separately, and may be stored together in one memory area. Also, the transmission identification code area 212 provided in the reception data management memory area 186
May be provided in the image / character data memory area 184. The management buffer memory area 192 is not essential, and the transfer may be performed while confirming the untransmitted identification code of the received data management memory 186 or the image / character data memory area 184.

Needless to say, the structure of each flow chart is not limited to that described, but the conditions for prohibiting transfer to the transfer destination are not limited to those described in this embodiment. For example, in the present embodiment, the condition is set so that the operation of the transfer means is prohibited when the reception is not normally completed, but, for example, except when the signal of the reception required notification such as the ID code is included. A condition such as prohibiting the reception notification may be set in the.

Further, in this embodiment, since the personal computer 4 is connected to the facsimile device 2, all the data received from the other facsimile device is stored in the personal computer via the facsimile device 2 and registered in the personal computer 4. The transfer may be performed based on the transfer destination.

Further, in S502 of FIG. 15 of the present embodiment, depending on whether or not the destination facsimile machine set by the communication protocol procedure has the BFT capability,
Whether to send the character data or the image data is selected, but each destination is a facsimile machine corresponding to the one-touch dial set in the RAM 170 or the telephone number stored in the speed dial memory area 195. Whether or not the facsimile machine is a BFT
Whether or not the system has the capability is also stored in a flag or the like, and the dial memory area 190 is stored based on the flag.
It may be determined whether or not the transfer destination facsimile machine stored in the table has the BFT capability.

By doing this, S502, S in FIG.
Since 503 and S504 can be performed prior to the transfer routine, the time and effort of confirming the capability of the other party by the communication protocol can be saved, the transmission can be performed more quickly, and the character data and the image data are converted at the time of transmission. There is no need to connect the telephone line and then perform conversion,
The time required for communication, and thus the communication cost, can be reduced.

In addition, the dial memory area 190
If it is determined in advance whether or not the transfer destination facsimile device has the BFT capability, it is known in advance that the transfer destination facsimile device does not have the BFT capability.
Therefore, since the data finally sent to the transfer destination must be image data, it is necessary to convert all the character data into image data even if the character data is transmitted by the BFT. Regardless of whether or not it has the BFT capability, the facsimile device 2 may send a pseudo notification to the other party that only the image data can be received, and the image data may be sent.

Besides, the present invention can be implemented in variously modified and improved modes based on the knowledge of those skilled in the art without departing from the scope of the claims.

According to the communication device of the first aspect of the invention, the detection result indicating whether the received data is character data or image data and the determination result indicating whether the transfer destination can receive the character data or the image data are used. Based on this, since the transfer of the received data is controlled, there is an effect that the received data can be efficiently transmitted according to the capability of the transfer destination.

Further, in the second invention, when it is detected that the received data is character data and it is determined that the transfer destination can receive the character data, the received character data is stored. Since the stored character data is transferred to the transfer destination, there is an effect that not only can the data be received and transferred quickly, but also the character data can be edited at the transfer destination.

Furthermore, in the third invention, when it is detected that the received data is character data and it is determined that the transfer destination can receive only the image data,
After storing the received character data and converting the stored character data into image data, the converted image data is transferred to the transfer destination, so that the received character data is reliably transmitted to the transfer destination. It has the effect of being able to.

In the fourth invention, when the received data is detected to be image data and it is determined that the transfer destination can receive the character data, the received image data is stored. Since the stored image data is converted to character data and then the converted character data is transferred to the transfer destination, not only can the transfer be performed quickly, but the character data can be edited at the transfer destination. And so on.

Further, in the fifth invention, which of the character data and the image data can be received by the transfer destination is stored in advance, and the capability of the transfer destination is determined based on the stored contents. Not only can the character data and the image data be converted in advance, but it is not necessary to confirm the transfer destination capability in the communication procedure, and the communication time and communication cost can be reduced.

Further, in the sixth invention, when the transfer destination can receive only the image data based on the stored contents, the sending side is informed that only the image data can be received. When it is known in advance that the image data has to be transferred, it is possible to save the trouble of converting the character data into the image data.
