[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a communication system that transmits and receives data and a program that can be used in a terminal device that constitutes the communication system.
[0002]
[Prior art]
Conventionally, for example, in a communication apparatus having a function as a facsimile, communication contents of communication data (for example, transmission destination, transmission source, communication date / time, communication time, number of pages, etc.) are stored (recorded) in a memory. Generally, the communication contents accumulated at the timing when a predetermined operation is performed are configured to be printed on a sheet. Thereby, the user can confirm the communication content on the paper.
[0003]
In recent years, a technique has been proposed for confirming the communication content of a communication device from the terminal device connected to the communication device so that data communication is possible. For example, a terminal device (personal computer PC) is provided with a recording unit (RAM 12) that can be recognized as an external recording device connected to the terminal device itself, and data indicating communication contents (facsimile transmission / reception data) is recorded in this recording unit. Thus, the communication device (data input / output device) can be freely checked for communication contents from the terminal device side (see Patent Document 1). With such a communication device, it is easy to transfer (record) data indicating the communication content by the communication device to the terminal device side, and the communication content by the communication device can be stored and managed as data on the terminal device side. This is preferable.

[0005]
[Problems to be solved by the invention]
However, since the communication device described above simply records data indicating communication contents in a state accessible from the terminal device side, the user can record the data recorded in the recording unit of the communication device. It is necessary to intentionally perform troublesome work such as saving to the side.
[0006]
For this reason, the above-described communication device cannot be said to be convenient for storing and managing communication contents as data on the terminal device side. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a technique for improving usability when storing and managing communication contents by a communication device as data on the terminal device side. It is.
[0007]
[Means for Solving the Problems and Effects of the Invention]
In order to solve the above problem, a communication system according to claim 1 is a communication system in which a communication device and a terminal device are connected so as to be capable of data communication. The communication device of this communication system includes communication means, communication side recording means, communication side check means, and communication side recording command means.
Among these, the communication means is Means and interface for communication via telephone network or the Internet Means for performing data communication via the network. The communication-side recording means can record various data and can be recognized as an external recording device connected to the terminal device. The communication-side checking means is means for checking a free area where data can be recorded in the communication-side recording means when communication data is transmitted or received by the communication means. Then, if the free area checked by the communication side check means is a free area that is equal to or larger than a predetermined area, the communication side recording command means sends the transmitted or received communication data to a single page consisting of one or more pages of page data. The data is recorded in the communication recording means as one data file.
[0008]
Further, the terminal device includes a terminal-side recording unit, a terminal-side checking unit, a terminal-side recording command unit, and a terminal-side deletion command unit. Among these, the terminal-side recording means is means for recording various data. The terminal side checking means Check the free space where data can be recorded in the communication-side recording means. Means. Also, the terminal-side recording command means If the free area checked by the communication-side check means is a free area that is equal to or larger than a predetermined area, the communication data transmitted or received by the first communication means is a single piece of page data for one or a plurality of pages. When the free area checked by the communication side check means is a free area less than a predetermined area, the data file is recorded by the first communication means as a data file. Alternatively, each of the page data in the received communication data is sequentially recorded on the communication side recording means via the second communication means. . Then, the terminal-side deletion command means receives the communication data in response to a command from the terminal-side recording command means. Via the first communication means In response to being recorded in the terminal-side recording means, from the communication-side recording means included in the communication device, Same as recorded in the terminal recording means Delete communication data.
[0009]
According to the communication system configured as described above, after communication data is recorded on the communication device side (communication side recording means), the communication data is automatically recorded on the terminal device side (terminal side recording means). Can do. Therefore, after communication is performed by the communication device and the communicated communication data is recorded on the communication device side, the user must intentionally operate the terminal device in order to record the communication data on the terminal device side. There is no. Therefore, it is easier to use when storing and managing the communication data communicated by the communication device on the terminal device side, compared to the conventional device that requires such an operation.
[0010]
Further, since the data recorded on the communication device side is deleted after this data is recorded on the terminal device side, unnecessary data is occupied on the communication device side (communication side recording means). There is no fear, and the recording area on the communication device side can be used effectively.
[0011]
Also If the free area checked by the communication side check means is less than the predetermined area, Communication data communicated by the communication device side can be recorded (transferred) to the terminal device side using a recording area smaller than the communication data itself.
[0012]
Note that the communication means included in the communication device described above is a means for performing data communication via a network. For example, a configuration for communicating image data (facsimile communication) via a telephone line network or the Internet, or via the Internet. A configuration for communicating various data can be considered.
[0013]
Further, the communication-side recording means accesses (records and deletes data) an external recording device connected to the terminal device, that is, via a function (file system) provided as a standard in an OS (operating system). It is a means that can be recognized as a recordable area.
[0014]
[0015]
Also, Page data As another configuration for restoring communication data from the following, the following configuration can be considered. In the communication device, the communication side recording command means Page data Each of them is sequentially recorded on the communication side recording means, and these Page data Specific data capable of specifying that each is data obtained by dividing communication data is recorded in the communication-side recording means. In addition, when the specific data was recorded in the communication-side recording means included in the communication device, the terminal device was recorded in the terminal-side recording means based on the specific data Page data The data synthesizing means for generating communication data by synthesizing each of them is provided.
[0016]
According to the communication system configured as described above, communication data is divided on the communication device side. Page data By recording specific data together with the terminal device, each terminal device side Page data Communication data can be generated (restored). Therefore, even if the division rule for dividing the communication data is not determined in advance, each terminal device side Page data Communication data can be restored from
[0017]
In addition, “specific data” in this configuration is Page data It is data that can specify that each is divided data of communication data. Specifically, for example, a procedure indicating how the divided data is divided (or restored), each of the divided data, Data that can specify the file name.
[0018]
Further, in this configuration, after the communication data is generated by the data synthesizing unit, the specific data recorded in the communication-side recording unit included in the communication device is unnecessary data, so it is desirable to delete it. As a configuration for this, for example, in the terminal device, when the terminal-side deletion command unit generates communication data by the data synthesis unit, the specific data recorded in the communication-side recording unit included in the communication device is deleted. It is possible to adopt a configuration such as With this configuration, there is no fear that the communication-side recording unit will occupy unnecessary specific data, and the recording area of the communication-side recording unit can be used effectively.
[0019]
As another configuration, in the terminal device, when the terminal-side recording command unit records the specific data in the communication-side recording unit included in the communication device, the specific data is stored in the terminal-side recording unit as follows. When the specific data is recorded on the terminal-side recording means by the command from the terminal-side recording command means, the terminal-side deletion command means deletes the specific data from the communication-side recording means included in the communication device, and the data The synthesizing means is based on the specific data recorded in the terminal side recording means. Page data It is also possible to consider a configuration in which each is synthesized.
[0020]
Similarly, according to the communication system configured as described above, there is no fear that the communication-side recording unit occupies unnecessary specific data, and the recording area of the communication-side recording unit can be used effectively. it can. The communication-side recording command means described above causes the communication-side recording means to record the communication data as divided data when the recording condition is not satisfied. At this time, the communication data transmitted or received by the communication means includes a plurality of communication data. If the data is composed of unit data (for example, a single page), the unit data may be configured to be sequentially recorded in the communication recording means as divided data.
[0021]
Specifically, as described below, in the communication apparatus, the communication unit is configured to transmit or receive communication data for each divided data, and the communication-side recording command unit transmits or receives communication data by the communication unit. When the recording condition is satisfied, the communication data composed of each divided data transmitted or received by the communication means is recorded on the communication-side recording means. On the other hand, if the recording condition is not satisfied, the divided data is transmitted by the communication means. Each time is sent or received page A configuration in which data is recorded in the communication-side recording means can be considered.
[0022]
According to the communication system configured as described above, when the communication data transmitted or received by the communication unit is composed of a plurality of unit data, the communication terminal transmits each of the unit data. page The data can be recorded on the communication recording means as data.
[0023]
The above-mentioned communication-side recording command means divides communication data into a certain amount of data. page Generate data and this page You may comprise so that data may be recorded on a communication side recording means sequentially. Specifically, as described below, in the communication device, when communication data is transmitted or received by the communication means, the communication data is stored when the recording condition is not satisfied. page Data dividing means for dividing each data is provided, and if the communication side recording command means does not divide the communication data by the data dividing means, the communication side recording means records the communication data, while the data dividing means Communication data page If divided into data, this page A configuration is conceivable in which each data is sequentially recorded by the communication-side recording means.
[0024]
According to the communication system configured as described above, communication data transmitted or received by the communication unit can be divided into a plurality of divided data and recorded on the communication-side recording unit. Various conditions can be considered as the “recording condition” described above. For example, when the remaining area indicating the remaining recording area for recording communication data in the communication-side recording means is equal to or greater than a predetermined threshold value. You can consider the conditions that are met.

According to the communication system configured as described above, on the communication device side, when the remaining area of the communication-side recording unit is smaller than a predetermined threshold value, the communication data is sequentially recorded on the communication-side recording unit as divided data. Can do. Therefore, if a recording area that is assumed to be sufficient for recording communication data is set as the above-described “threshold value”, the remaining area of the communication-side recording means is sufficient to record communication data. When the area is smaller than the area, the communication data can be divided and sequentially recorded, so that the communication data can be recorded on the terminal device side while effectively using the remaining remaining area.
[0026]
In addition, as the “recording condition” described above, a condition that is satisfied when a parameter related to communication data transmitted or received by the communication unit is a specific parameter can be considered as follows. According to the communication system configured as described above, on the communication device side, when the parameter related to the communication data is a specific parameter, the communication data can be sequentially recorded on the communication side recording unit as the divided data. Therefore, as the above-mentioned “specific parameter”, for example, the amount of communication data that is assumed to occupy most of the recording area of the communication-side recording means or larger than the recording area of the communication-side recording means. If the parameter is set, if the data amount of communication data occupies most of the recording area of the communication-side recording means or becomes larger than the recording area of the communication-side recording means, the communication data is divided and sequentially Since it can be recorded, communication data can be recorded on the terminal device side while effectively using a small remaining area.
[0027]
As a specific example of the “parameter” in this configuration, for example, when the communication device communicates image data as communication data, the number of colors of the image indicated by the image data can be considered. In this case, the “recording condition” is satisfied when the number of colors is a predetermined number or more.
[0028]
According to the communication system configured as described above, on the communication device side, when the number of colors of the image indicated by the image data is equal to or larger than the predetermined number, the communication data is sequentially recorded on the communication side recording unit as divided data. Can do. Therefore, as the above-mentioned “predetermined number”, for example, the color of the image data that the data amount is assumed to occupy most of the recording area of the communication-side recording means or larger than the recording area of the communication-side recording means If the number is set, if the data amount of communication data occupies most of the recording area of the communication-side recording means or becomes larger than the recording area of the communication-side recording means, the communication data is divided and sequentially Since it can be recorded, communication data can be recorded on the terminal device side while effectively using a small remaining area.
[0029]
As a specific example of the “parameter” described above, for example, when the communication apparatus communicates image data as communication data, the resolution of the image indicated by the image data can be considered. In this case, the “recording condition” is satisfied when the resolution is equal to or higher than a predetermined threshold value.
[0030]
According to the communication system configured as described above, on the communication device side, when the resolution of the image indicated by the image data is equal to or higher than a predetermined threshold, the communication data is sequentially recorded as divided data on the communication-side recording unit. Can be made. Therefore, as the above-mentioned “threshold value”, for example, the amount of image data that is assumed to occupy most of the recording area of the communication-side recording means or larger than the recording area of the communication-side recording means. If the resolution is set, if the amount of communication data occupies most of the recording area of the communication-side recording means or becomes larger than the recording area of the communication-side recording means, the communication data is divided and sequentially Since it can be recorded, communication data can be recorded on the terminal device side while effectively using a small remaining area.
[0031]
Further, as the above-mentioned “recording condition”, the communication device receives the operation of the user, the operation mode of the communication device itself, and the communication data itself when the communication data is transmitted or received by the communication means. There is provided a mode switching means capable of switching between a normal mode for recording in the recording means and a divided mode for recording the divided data in the communication-side recording means when the communication data is transmitted or received by the communication means. In this case, it is possible to consider a condition that is satisfied when the operation mode of the communication device itself is switched to the normal mode by the mode switching unit.
[0032]
According to the communication system configured as described above, on the communication device side, when the operation mode of the communication device itself is switched to the divided mode, the communication data can be sequentially recorded as the divided data on the communication-side recording unit. it can.

The external I / F 232 is an interface for connecting the PC 200 to the multi-function device 100 via the communication cable 300, thereby enabling data communication between the PC 200 and the multi-function device 100.
[0054]
The input unit 240 is an input device including a keyboard 242 and a mouse 244.
○ FAX reception processing by the CPU 132 of the MFP 100
Hereinafter, a processing procedure of FAX reception processing executed by the CPU 132 included in the multifunction peripheral 100 will be described with reference to FIG. This FAX reception process is started when input of an image signal is started from the telephone line network 400 via the line control unit 174.
[0055]
First, the line control unit 174 is caused to set a path connecting the modem 154 and the telephone line network 400 as a signal transmission path (s110). As a result, the image signal can be transmitted through a path connecting the modem 154 and the telephone line network 400. Next, it is checked whether or not the free space in the shared area in the RAM 140 is sufficient to record image data received by fax communication (s120). In this process, if the free space in the shared area is equal to or greater than a predetermined threshold (256 kbytes in this embodiment), it is determined that the image data is sufficient for recording.
[0056]
If the free space in the shared area is sufficient to record image data in the process of s120 (s120: YES), an image signal for a single page is received by facsimile communication (s130). Next, it is checked whether there is a subsequent page (s140). In this process, after reception of an image signal for a single page in the process of s130, when reception of an image signal indicating a subsequent page is started, it is determined that a subsequent page exists.
[0057]
If there is a subsequent page in the process of s140 (s140: YES), the process returns to the process of s130. Thus, after the processes of s130 and s140 are repeated, if there are no subsequent pages in the process of s140 (s140: NO), the image indicated by the image signal for one or more pages received repeatedly in the process of s130 Are recorded in a shared area of the RAM 140 as a single data file (s150). In this process, the image signal for one or a plurality of pages repeatedly received in the process of s130 is demodulated and decoded by the modem 154 to obtain image data for one or a plurality of pages, and then the image data is shared by the RAM 140. Record in the area. After this image data is recorded in the shared area, it is read and deleted on the PC 200 side by a data collection process (FIG. 5) described later. In this process of s150, the image data is recorded with a file name including a numeric string concatenated with the date and time when the process of s130 was performed. For example, when the communication date is “2003.03.20” and the communication time is “9:45”, the file name is “rx200303200945”.
[0058]
Then, after the line control unit 174 cancels the setting as the transmission path of the path connecting the modem 154 and the telephone line network 400 (s160), the FAX reception process is terminated. By the processing of s160, the image signal is not transmitted through the path connecting the modem 154 and the telephone line network 400.
[0059]
If the free space in the shared area is not sufficient for recording the image data in the process of s120 described above (s120: NO), the variable N is initialized (s170). In this process, the variable N is set to “1” (1 → N). Note that “n” described below indicates a value set in the variable N.
[0060]
Next, an image signal for a single page is received by facsimile communication (s180). Next, the image data of the image indicated by the image signal for a single page received in the process of s170 is recorded in the shared area of the RAM 140 (s190). In this process, the image signal for a single page repeatedly received in the process of s180 is demodulated and decoded by the modem 154 to be image data for one page, and then this image data is recorded in the shared area of the RAM 140. Let After this image data is recorded in the shared area, it is read and deleted on the PC 200 side by a data collection process (FIG. 5) described later. In this process of s190, the image data is recorded with a file name consisting of a numeric string concatenating the date and time when the process of s180 was performed and the value of variable N (ie, page number). For example, if the communication date is “2003.03.20”, the communication time is “9:45”, and the value of the variable N is “1”, the file name is “rx200303200945p001”.
[0061]
Next, it is checked whether or not there is a subsequent page (s200). In this process, after receiving an image signal for a single page in the process of s180, when reception of an image signal indicating a subsequent page is started, it is determined that there is a subsequent page.
[0062]
In the process of s200, when there is a subsequent page (s200: YES), “1” is added to the variable N (1 + n → N) (s210), and the process returns to s180. In this way, after the processing from s180 to s210 is repeated, if there is no subsequent page in the processing of s200 (s200: NO), the image data for one or more pages recorded in the shared area in the processing of s190 is one. Specific data indicating that the data has been received by the first facsimile communication is generated and recorded in the supply area of the RAM 140 (s220). In this process, as shown in FIG. 4, the file name of each image data recorded in the process of s190 and the file name of the image data to be generated by combining these image data (hereinafter referred to as the combined file name). Is generated as specific data, and then recorded in the shared area of the RAM 140. After this specific data is recorded in the shared area, it is read and deleted on the PC 200 side in a data collection process (FIG. 5) described later. In this embodiment, the composite file name is a name obtained by deleting the page number from the file name having the largest page number among the image data recorded in the process of s190 (“to” rx200303200947 in FIG. 4). )reference).
[0063]
In this way, after finishing the process of s220, after canceling the setting as a transmission path by the process of s160, this FAX reception process is complete | finished. In addition, while the processes from s130 to s140 described above are performed and during the processes from s180 to s210 are performed, they are sequentially input from the telephone line network 400 (transmission source) via the line control unit 174. The image signal for a single page is demodulated and decoded by the modem 154 to be converted into image data for one page, and is then sequentially printed by the printer unit 156. Since it is not important for understanding the invention, it is omitted.
○ Data collection processing by CPU212 of PC200
Hereinafter, a processing procedure of data collection processing executed by the CPU 212 provided in the PC 200 will be described with reference to FIG. This data collection process is repeatedly executed from when the data collection program is started until it is terminated.
[0064]
First, it is checked whether image data has been recorded in the shared area of the RAM 140 included in the multifunction peripheral 100 (s310). The image data is recorded on the multi-function peripheral 100 side by the processes of s150 and s190 in FIG. When image data is recorded in the shared area in the process of s310 (s310: YES), this image data is read and recorded in the HD 220 (s320). In this process, the image data is recorded in a recording area of the HD 220 that is predetermined as a recording location where the image data is to be recorded.
[0065]
Next, the same data as the image data recorded on the HD 220 in the process of s320 is deleted from the shared area (s330). In this way, after the processing of s330 is completed, or when image data is not recorded in the processing of s310 (s310: NO), it is checked whether specific data is recorded in the shared area of the RAM 140 included in the multifunction peripheral 100. (S340). The specific data is recorded by the process of s220 in FIG.
[0066]
If the specific data is not recorded in the shared area in the process of s340 (s340: NO), the process returns to the process of s310. In this way, by repeating the processing from s310 to s340, the image data repeatedly recorded in the shared area by the processing from s180 to s220 in FIG. 3 on the multi-function peripheral 100 side is sequentially read out, recorded in the HD 220, and then deleted from the shared area. It will be.
[0067]
If specific data is recorded in the shared area in the process of s340 (s340: YES), the specific data is read and recorded in the HD 220 (s350). In this process, the specific data is recorded in a recording area of the HD 220 that is predetermined as a recording location where the specific data is to be recorded.
[0068]
Next, the same data as the specific data recorded on the HD 220 in the process of s350 is deleted from the shared area (s360). Next, based on the specific data recorded on the HD 220 in the process of s350, the image data recorded in the process of s320 are combined to generate a single data file (s370). In this process, image data formed by concatenating each image file specified by the specific data in the order of page numbers is generated as data of a composite file name specified by the specific data.
[0069]
Next, the specific data recorded in the process of s350 is deleted from the HD 220 (s380). Then, after deleting each image data recorded in the process of s320 from the HD 220 (s390), the process returns to the process of s310.
[0070]
[Effect of the first embodiment]
According to the communication system 1 configured as described above, after image data or specific data is recorded on the multifunction peripheral 100 side (shared area of the RAM 140) (processing of s150, s190, and s220 in FIG. 3), this data is stored. It can be automatically recorded on the PC 200 side (HD 220) (processing of s320 and s350 in FIG. 5). For this reason, facsimile communication is performed by the multifunction device 100, and after image data received by this communication or generated specific data is recorded on the multifunction device 100 side, a user has to record these data on the PC 200 side. There is no need to intentionally operate the PC 200. Therefore, compared with the conventional one that requires such an operation, the usability when storing and managing the image data received by the multifunction peripheral 100 or the specific data to be generated on the PC 200 side is better.
[0071]
Further, since the data recorded on the multifunction device 100 side (shared area of the RAM 140) is deleted after this data is recorded on the PC 200 side (processing of s330 and s360 in FIG. 5), the data recorded on the multifunction device 100 side is deleted. There is no risk of occupying unnecessary data, and the recording area on the multifunction peripheral 100 side can be used effectively.
[0072]
Furthermore, when the image data is received, if the free space in the shared area is not sufficient, the multifunction apparatus 100 sequentially records the image data for each single page of image data in the shared area (s180 in FIG. 3). To s210). Each time image data for a single page is recorded in the shared area, it is sequentially recorded on the PC 200 side and then deleted. Therefore, in a state where the free capacity of the shared area is not sufficient, the image data received by the multifunction peripheral 100 can be recorded (transferred) on the PC 200 side using a recording area smaller than the image data itself.
[0073]
Further, by recording specific data together with image data for a single page in the shared area on the multi-function peripheral 100 side (processing of s220 in FIG. 3), on the PC 200 side, each image data is simply set based on this specific data. Image data combined as a single data file can be generated (restored) (processing of s370 in FIG. 5).
[0074]
On the MFP 100 side, when the free space of the shared area in the RAM 140 is smaller than a predetermined threshold (the process of s120 in FIG. 3), image data for a single page is sequentially recorded in the shared area. (Processing of s190). In the present embodiment, the “threshold value” is a free space that is assumed to be sufficient for recording image data received by facsimile communication, so that the free space in the shared area is sufficient to record the image data. Since the image data can be sequentially recorded for each single page when the amount is less than the free space, the image data can be recorded on the PC 200 side while effectively using the small free space.
[0075]
[Second Embodiment]
The communication system 2 has the same configuration as the communication system 1 in the first embodiment, and only a part of the processing procedure is different. Therefore, only this difference will be described in detail.
○ FAX reception processing by the CPU 132 of the MFP 100
The FAX reception process in the second embodiment is configured to perform the following processes of s122 and s124 instead of the process of s120 in FIG. 3, and these processes will be described with reference to FIG.
[0076]
First, after setting the transmission path in the process of s110, it is checked whether the image data received by facsimile communication is color image data (s122). In facsimile communication, normally, prior to receiving an image signal, the image data indicated by the image signal is color or monochrome, and the image data indicated by the image signal is image data having a normal resolution. Since an image information signal indicating whether the image data has a high resolution (a resolution higher than normal) is exchanged, in the process of s122, it is checked whether or not the color is based on the image information signal. In the process of s122, when the image data received by facsimile communication is color image data (s122: YES), the process proceeds to s170.
[0077]
On the other hand, when the image data received by facsimile communication is monochrome image data in the process of s122 (s122: NO), it is checked whether the image data received by facsimile communication is high-resolution image data. (S124). In this processing, it is checked whether the resolution is a normal resolution or a high resolution based on the above-described image information signal.
[0078]
In the process of s124, when the image data received by facsimile communication is high-resolution image data (s124: YES), the process proceeds to s170, while when the image data is normal-resolution image data (s124: NO). ), And the process proceeds to s130.
[0079]
[Effect of the second embodiment]
According to the communication system 2 configured as described above, the following effects can be obtained as effects obtained from a configuration different from that of the first embodiment. According to this communication system 2, when image data received by facsimile communication is color or high-resolution image data on the multi-function device 100 side (processing of s122 and s124 in FIG. 6), the image data is converted into a single page. The image data can be sequentially recorded in the shared area (processing from s180 to s210). Usually, color or high-resolution image data has a larger amount of data than monochrome or normal-resolution image data. Therefore, when this image data is recorded as it is in the shared area, the image data is stored in the recording area of the shared area (free space). (Capacity) is mostly occupied, or the image data becomes larger than the recording area (free capacity) of the shared area and cannot be normally recorded. Therefore, in the case of color or high-resolution image data, sequentially recording the image data for each single page of image data prevents the image data from occupying most of the recording area of the shared area. Also, it is suitable for preventing the image data from being normally recorded due to the image data becoming larger than the recording area of the shared area. As a result, the image data recorded in the multifunction peripheral 100 can be recorded on the PC 200 side while effectively using the free space in the shared area.
[0080]
[Third embodiment]
The communication system 3 has the same configuration as the communication system 1 in the first embodiment, and only a part of the processing procedure is different. Therefore, only this difference will be described in detail.
○ Mode switching processing by the CPU 132 of the multifunction device 100
Hereinafter, a processing procedure of mode switching processing executed by the CPU 132 included in the multifunction peripheral 100 will be described with reference to FIG. This mode switching process is started when the function determination button 124 of the operation panel 120 is pressed twice in succession. First, an operation mode switching menu is displayed on the display panel 114 (s410). In this process, the operation mode of the multifunction peripheral 100 is set to “normal mode” in which image data is recorded in the shared area of the RAM 140 as it is in a FAX reception process (FIG. 8) described later, and the image data is image data for each single page. As a result, an operation mode switching menu that prompts the user to switch to one of “divided modes” that are sequentially recorded in the shared area of the RAM 140 is displayed. After the operation mode switching menu is displayed on the display panel 114, the user operates the direction button 125 of the operation panel 120 to select either the normal mode or the division mode, and then presses the function determination button 124. An operation (mode determination operation) such as pressing is performed.
[0081]
Next, the process waits until a mode determination operation is performed (s420: NO). If a mode determination operation is performed in the process of s420 (s420: YES), the operation mode is switched (s430). In this processing, “0” is set as an initial value, and the operation mode is set by setting a value corresponding to the operation mode determined by the mode determination operation to the variable M for setting a value indicating the operation mode. Switch. Specifically, when the operation mode is determined as “normal mode”, “0” is set (0 → M), and when it is determined as “division mode”, “1” is set (1). → M). Note that “m” described below indicates the value set in the variable M.
[0082]
Then, after the display of the operation mode switching menu is erased from the display panel 114 (s440), this mode switching process is terminated.
○ FAX reception processing by the CPU 132 of the MFP 100
The FAX reception process in the third embodiment is configured to perform the following process of s126 instead of the process of s120 in FIG. 3, and this process will be described with reference to FIG.
[0083]
First, after setting the transmission path in the process of s110, the operation mode of the multifunction peripheral 100 itself is checked (s126). In this process, it is determined whether the operation mode switched in the mode switching process of FIG. 7 is the “normal mode” or the “division mode” based on the value set in the variable M described above (M = 0 → “normal mode”, M = 1 → “split mode”).
[0084]
In the process of s126, when the operation mode is the “normal mode” (s126: YES), the process proceeds to the process of s130, while in the “division mode” (s126: NO), the process proceeds to the process of s170.
[Effect of the third embodiment]
According to the communication system 3 configured as described above, the following effects can be obtained as the effects obtained from the configuration different from the first embodiment.
[0085]
According to the communication system 3, when the operation mode of the multifunction device 100 is switched to the split mode on the multifunction device 100 side (the process of s126 in FIG. 8), the image data is image data for each single page. The data can be sequentially recorded in the shared area (processing from s180 to s210). The operation mode of the MFP 100 is switched in response to a user operation in the mode switching process of FIG. Therefore, the user can arbitrarily change whether the image data itself is recorded or whether the image data is recorded as image data for each single page.
[0086]
[Fourth embodiment]
The communication system 4 has the same configuration as the communication system 1 in the first embodiment.
○ FAX reception processing by the CPU 132 of the MFP 100
Hereinafter, a processing procedure of FAX reception processing executed by the CPU 132 included in the multifunction peripheral 100 will be described with reference to FIG. This FAX reception process is started when input of an image signal is started from the telephone line network 400 via the line control unit 174.
[0087]
First, the line control unit 174 is caused to set a path connecting the modem 154 and the telephone line network 400 as a signal transmission path (s510). Next, an image signal for a single page is received by facsimile communication (s520).
[0088]
Next, it is checked whether there is a subsequent page (s530). This process is the same as the process of s140 in FIG. If there is a subsequent page in the process of s530 (s530: YES), the process returns to the process of s520.
[0089]
In this way, after the processing of s520 and s530 is repeated, if there is no subsequent page in the processing of s530 (s530: NO), the free space in the shared area in the RAM 140 records the image data received by fax communication. It is checked whether or not it is sufficient (s540). This process is the same as the process of s120 in FIG.
[0090]
When the processing in s540 has enough free space in the shared area to record image data (s540: YES), the image indicated by the image signal for one or more pages repeatedly received in the processing in s520 is displayed. The image data is recorded as a single data file in the shared area of the RAM 140 (s550). This process is the same as the process of s150 in FIG.
[0091]
Then, after the line control unit 174 cancels the setting as the transmission path of the path connecting the modem 154 and the telephone line network 400 (s560), the FAX reception process is terminated. If the free space in the shared area is not sufficient for recording image data in the above-described processing of s540 (s540: NO), the variable N is initialized (s570). In this process, the variable N is set to “1” (1 → N). Note that “n” described below indicates a value set in the variable N.
[0092]
Next, the image data of the image indicated by the image signal for one or a plurality of pages repeatedly received in the process of s520 is divided into divided data for each predetermined data amount (256 kbytes in the present embodiment) (s580). ). In this process, image data of an image indicated by image signals for a plurality of pages is regarded as a single data file, and the data is divided into a plurality of first to i-th divided data divided by a predetermined data amount. .
[0093]
Next, the nth divided data divided in the process of s580 is recorded in the shared area of the RAM 140 (s590). In this process, a file name consisting of a numeric string concatenated with the date and time when the process of s590 is performed and the value of variable N (that is, the order from 1 to i) is recorded. For example, when the communication date is “2003.03.20”, the communication time is “9:45”, and the value of the variable N is “1”, the file name is “rx200303200945t001”. The divided data is recorded in the shared area, and then read and deleted on the PC 200 side (processing of s320 and s330 in FIG. 5).
[0094]
Next, it is checked whether or not the (n + 1) th divided data exists (s600). In this process, when the value of “n + 1” is larger than the value “i” indicating the final number of the divided data (i ≦ n + 1), it is determined that the (n + 1) th divided data exists.
[0095]
In the process of s600, when the (n + 1) th divided data exists (s600: YES), the process waits until the nth divided data recorded in the shared area of the RAM 140 is deleted in the process of s590 (s610: NO). If the nth divided data is deleted in the process of s610 (s610: YES), “1” is added to the variable N (1 + n → N) (s620), and the process returns to the process of s590.
[0096]
Thus, after repeating the processing from s590 to s620, if there is no (n + 1) th divided data in the processing of s600 (s600: NO), one or more pieces of divided data repeatedly recorded in the shared area in the processing of s590 are once. Specific data that can specify that the image data received by the facsimile communication is divided data is generated and recorded in the supply area of the RAM 140 (s630). In this process, the file name of each divided data recorded in the process of s590, the processing procedure for synthesizing each divided data, and the file name of the image data obtained by synthesizing the divided data (hereinafter referred to as a synthesized file name). Is generated as the specific data and then recorded in the shared area of the RAM 140. The specific data is recorded in the shared area, and then read and deleted on the PC 200 side. The composite file name is a name obtained by deleting the page number from the file name having the largest page number among the image data recorded in the process of s590. Further, the processing procedure for synthesizing the respective divided data is a procedure (for example, a known division or combination algorithm) indicating how the divided data can be restored.
[0097]
Then, after finishing the processing of s630, the setting as the transmission path is canceled in the processing of s560, and then this FAX reception processing is finished. While the processing from s520 to s530 is performed, processing related to normal facsimile communication is performed as in the first embodiment, but is omitted because it is not important for understanding the present invention.
○ Data collection processing by CPU212 of PC200
In the data collection process in the fourth embodiment, when the divided data (recorded in the process of s590 in FIG. 9) is recorded in the shared area of the RAM 140 of the multi-function peripheral 100 by the process of s310 in FIG. This divided data is read by processing and recorded on the HD 220, and then the same data as the divided data recorded on the HD 220 by processing of s320 is deleted from the shared area by processing of s330. .
[0098]
[Effect of the fourth embodiment]
According to the communication system 4 configured as described above, the following effects can be obtained as the effects obtained from the configuration different from the first embodiment.
According to the communication system 4, the image data received by the multifunction peripheral 100 can be divided into a plurality of divided data and recorded in the shared area of the RAM 140 (processing of s580 in FIG. 9).
[0099]
Further, by recording the specific data together with the divided data in the shared area on the MFP 100 side (processing of s630 in FIG. 9), on the PC 200 side, each divided data is converted into a single data file based on the specific data. The combined image data can be generated (restored) (the process of s370 in FIG. 5). Since this specific data is data that can specify a procedure indicating how the divided data can be restored by combining the divided data, each piece of divided data can be obtained on the PC 200 side without determining rules for dividing the image data in advance. Image data can be generated.
[0100]
