Data identifying and transmitting means for identifying the transmitted data by the table stored in the table storing means and sending it to a predetermined destination are provided (corresponding to the invention according to claim 1). The present invention is also characterized in that various means as described below are provided.

A table transmitting means for transmitting the table stored in the table storing means in the management device 1 from the communication control device 4 is provided (corresponding to the invention of claim 2).

A table initial value setting means is provided for automatically setting a predetermined initial value in the table stored in the table storage means in the management device 1 when the management device 1 is first powered on (claim 3). Corresponding to the described invention).

A table changing means for changing the table stored in the table storing means in the management device 1 via the communication control device 4 during transmission of the table is provided (corresponding to the invention of claim 4).

When changing a table stored in the table storage means in the management device 1, if there is data classified by the old table, the table is changed after all the old data is processed. A rear table changing means is provided (corresponding to the invention of claim 5).

When changing the table stored in the table storage means in the management apparatus 1, if there is data classified by the old table, it is necessary to confirm that the host machine 8 has the old data before changing the table. A table automatic changing means after data notification for automatically changing the table after the notification is provided (corresponding to the invention of claim 6).

When the table stored in the table storage means in the management apparatus 1 is changed, if there is already data classified by the old table, the host machine 8 is notified before the change and the host A table instruction changing means after data notification for changing the table according to the instruction of the machine 8 is provided (corresponding to the invention according to claim 7).

When the table stored in the table storage means in the management apparatus 1 is changed, if there is already data classified by the old table, the table is changed when the host machine 8 detects the table before the change. Data collection temporary interruption means after data detection is provided for temporarily interrupting the collection of data from the copying machine 5 until the change (corresponding to the invention of claim 8).

Hereinafter, the various means (calling destination storage means, table storage means, data identification transmission means, table transmission means table initial value setting means, table changing means, post-data processing table changing means, data notification according to the present invention will be described. The subsequent table automatic changing means, the table instruction changing means after data notification, and the data collection temporary interruption means after data detection) will be sequentially described in detail.

First, the outline of the processing method of the remote notification operation of the copying machine 5 according to the present invention will be described. Generally, a counter value such as the total number of copies is used to make a maintenance contract or maintenance of the copying machine 5. As a method of performing maintenance using such a counter value, by using the image forming apparatus management system,
Even if the copying machine 5 is in a communication-disabled state such as when the power of the copying machine 5 is turned off, the counter value of the total number of copies is periodically transmitted from the copying machine 5 to the communication control device 4. It becomes possible for the side to know the count value. That is, as the first method, the remote notification key (b) of the copying machine 5 is pressed to transmit the remote notification data from the copying machine 5 to the communication control device 4, and the communication control device 4 further manages the data. There is a method to call the telephone number of and send the data of the remote notification.

As the second method, there is a method in which the communication control device 4 reads out the information inside the copying machine 5 and holds the data inside the communication control device 4. In this case, all the copying machines 5 connected to the device 4 are reached when the total counter value collection time in the parameters set in the device 4 is reached with reference to the clock in the communication control device 4. The request for the total copy number information is sequentially made every day. Copy machine 5 responded
The new total copy number information of (3) is stored in the communication control device 4 by updating the value read on the previous day including the date when the total copy number was acquired. Further, when the power of the copying machine 5 for which the total copy number information is requested is cut off and the communication is not possible, the response reception of the data from the copying machine 5 is postponed to the next copying machine 5. To process. Then, when the request is made to all the copying machines 5, only the copying machine 5 which cannot receive the request is made again. Normally, the total counter value collection time is set at night when the power of the copying machine 5 is considered to be cut off, and the copying machine 5 is powered on as time passes. Immediately after the idling and adjustment of each part, such data communication is performed.

As the third method, there is a method of transmitting / receiving data between the communication control device 4 and the management device 1 by using the information on the total number of copies stored / held in the communication control device 4. is there. That is, a method of periodically reading by access from the management device 1 on the closing day of each month, and a method of managing by the communication control device 4 when the automatic call date and time of the total counter value set in the communication control device 4 is reached. There are two methods: automatic transmission to the device 1. Such a method is set by the total counter value automatic call permission SW 16 (see FIG. 2) provided in the communication control device 4. In this case, when the total counter value automatic call permission SW 16 is ON, when the date and time indicated by the parameter set in the communication control device 4 is reached,
The call destination telephone number indicated by the parameter set in the communication control device 4 is called, and the counter value of the total number of copies is transmitted to the management device 1. When the total counter value automatic call permission SW 16 is OFF, the automatic call is not made and the access from the management device 1 is waited for. In addition, in such an example, the data to be regularly communicated is the counter value of the total number of copies, but other data may be used, or another data may be added to perform the communication. In this system, the communication control device 4 can also shorten the access time by not issuing a data request to the unconnected copying machine.

Next, a specific example of the above-described processing method (first to third methods) of the remote notification operation will be described with reference to FIGS. 10 to 13. First, the function of remote notification will be described with reference to FIG. FIG. 10 (a) shows an example of remote notification by the remote notification key (b). Copier 5
When the upper remote notification key (b) is pressed, the remote notification data is transmitted to the communication control device 4. By this reception, the telephone number of the management device 1 set in the communication control device 4 in advance is called from the management device 1 via the public line 2 and the remote notification data is transmitted. At this time, the data transmitted to the management device 1 is the communication control device 4
Transmits to the management device 1 only the data of the preset type from the data of the plurality of models received from the copying machine 5. Then, when the communication control device 4 finishes transmitting the predetermined data to the management device 1, the communication control device 4
Transmits a report result report indicating the result of communication between the communication control device 4 and the management device 1 to the copying machine 5 which is the transmission source. As a result, the copying machine 5 that is the transmission source can know whether the communication has ended normally or the communication could not be performed due to some abnormality.

FIG. 10 (b) shows an example of remote notification due to a self-diagnosis abnormality. Normally, the copying machine 5 is equipped with a self-diagnosis function, and the copying machine 5 is in a dangerous state or in an unusable state such as when an abnormality in the fixing temperature is detected or when the electronic volume of each adjustment position cannot be adjusted. In the case of, the user or service person is notified in the form of an error or a service person call. Even when an abnormality is detected by such a self-diagnosis function of the copying machine 5, the copying machine 5 transmits the remote notification data due to the self-diagnosis abnormality to the communication control device 4.
The communication control device 4, which has received the remote notification data,
Similar to the case where the remote report key (b) is pressed, remote report data is transmitted to the management device 1, and at the end of communication, the report result report is transmitted to the copying machine 5 which is the transmission source.

FIG. 10 (c) shows an example of remote notification by prior report. When the copier 5 determines that it is preferable to perform maintenance, such as when the abnormal condition is not reached due to the self-vibration function but it is very close to the abnormal condition, remote notification data of advance warning is transmitted to the communication control device 4 as a warning. . In the case of a remote notification due to an abnormal self-determination, the copying machine 5 is inevitably in a disabled state. However, in the case of a remote notification due to a prior warning, the copying machine 5 remains in the usable state and communication is in progress. When the original is set and the start key is pressed, the copying operation is performed. At this time, the communication may be interrupted when the load of the controller is heavy due to the copying process or when the contents included in the transmission data may be changed by the copying operation to cause inconsistency. Since such remote notification data for advance warning is of low urgency, the communication control device 4 which receives the remote notification data does not immediately transmit it to the management device 1, but the telephone 6 connected to the communication control device 4 or The transmission is performed at a time convenient for communication such as a time period when the use frequency of the facsimile 7 is low or a time period when the traffic of the public line 2 is low. Such time setting is performed by the management device 1
Can be set to the communication control device 4. Unlike the other remote reports, the remote report of the advance warning does not send the report result report to the copying machine 5.

Based on FIG. 11, the management apparatus 1 to the copying machine 5
The case of accessing to is explained. This access method is roughly classified according to purpose, and read request, Write
There are three types: request and execute request. Figure 11
(A) shows a Read process, which is a process of reading logging data, various set values, output values of various sensors, and the like in the copying machine 5. 11 (b) is Write
The processing is to indicate processing, and is processing for rewriting by sending data from the management device 1 to various setting values and the like. Figure 11
(C) shows an Execute process, which is a process for causing the copying machine 5 to perform a test operation or the like. In any case, the management device 1 dials the communication control device 4 to which the target copying machine 5 is connected, and the communication control device 4 receives the requested data. Communication control device 4 that received the request data
Sends the request data to the target copying machine 5. Upon receiving the request, the copying machine 5 processes the request content and then transmits a response to the request to the communication control device 4. The communication control device 4 transmits this to the management device 1, thereby ending one processing unit.

The case of accessing the communication control device 4 from the management device 1 will be described with reference to FIG.
This access method is roughly classified into three types, a read request, a write request, and an execute request, according to the purpose. FIG. 12A shows a read process, which is a process of reading setting parameters and status in the communication control device 4, and a process of reading the information in the copying machine 5 in advance by the communication control device 4 and reading the information in the communication control device 4. If it is stored in, the process is such that it is read out. FIG. 12B shows Write processing, in which the parameters of the communication control device 4 are set to the management device 1.
The process of sending and setting data from the. 12
(C) shows an Execute process, which is a process for causing the communication control device 4 to perform a test operation such as a function check.

Based on FIG. 13, without using the management apparatus 1,
A case where the communication control device 4 accesses the copying machine 5 will be described. FIG. 13 shows the case of the Read process. In this access, the communication control device 4 reads the information in the copying machine 5 and holds the data in the communication control device 4, and then, as necessary. It refers to a reading process for enabling reading from the management device 1.

Next, the configuration of the data parameters and data format used when performing the access processing of the remote notification operation will be described with reference to FIGS. 14 to 18. First,
FIG. 14 shows a list of various parameters stored in the communication control device 4. A model number 90 and a serial number 91 of the copying machine 5 are registered for each of the copying machines 5 of the addresses ~. When the copying machine 5 makes a report, the model number 90 and the serial number 91 are added and transmitted to the management apparatus 1 or the management apparatus. It is used to determine the address of the copying machine 5 to be selected when accessing from 1. Further, the function of the checksum 92 is added, and it is possible to detect when the parameter value is rewritten or lost due to a malfunction of the communication control device 4 or an error in communication of the backup battery. Further, a telephone number 93 to be notified, a number of redials 94, a redial interval 95, and a type of data to be transmitted to the management device 1 (number of jams, number of copies, etc.) 96 are set for each remote reporting reason. These parameters are written from the management device 1 side through the public line 2, and a portable device for parameter setting is directly connected to the communication control device 4 for writing, or an operating means is provided on the communication control device 4 to set them. It may be configured.

In this case, since the parameter setting is important, the confidentiality is improved by adding an ID (password) to the communication data. This ID is not determined uniquely to each communication control device 4, and is determined when the first parameter is specified. After that, the communication control device 4 cannot be changed, and the communication control device 4 must be initialized manually. It becomes possible by. Since the ID is confirmed every time communication is made, erroneous data cannot be entered from different systems. When a different ID is received a predetermined number of times, this error is stored internally and the management device 1 is automatically notified to notify the system administrator. Every time such ID communication is performed, confirmation is performed to prevent hackers and the like. In this example, the ID cannot be changed by communication, but the contents may be changed by using the second changing password.

FIG. 15 shows an example of the format of the communication data format during remote notification. FIG. 15A shows
The data format sent from the copying machine 5 to the communication control device 4 is shown. The first field is the report reason code 97, which is a remote report by the remote report key (b),
There are two types: remote notification due to abnormal self-diagnosis and remote notification of advance warning. The copier status 98 includes information such as the status of consumables such as toner, oil, copy paper, output values of various sensors, setting values of various adjustment points, and connection status of units. FIG. 15B shows a configuration example of the data format sent from the communication control device 4 to the management device 1. In addition to the data from the copying machine 5, fields of a model number 90 and a serial number 91 are added at the beginning to identify the copying machine 5 that is the information generation source. Further, at the rear part, the time of occurrence 99 at which the reporting factor occurred is provided by the clock in the communication control device 4. In the data area, the type of data to be transmitted to the management apparatus 1 varies depending on the parameters installed in the communication control apparatus 4, but here, only the self-diagnosis abnormality occurrence count 100 and the copying machine status 98 are transmitted to the management apparatus 1. In this example, the parameters are set in the communication control device 4. FIG. 15C shows a configuration example of the data format sent from the communication control device 4 to the copying machine 5. When the notification from the communication control device 4 to the management device 1 is completed, it shows the contents of the notification result transmitted to the copying machine 5, and includes a notification result report code 101 and a notification result report content 102. .

FIG. 16 shows an example of the structure of the data format when the management apparatus 1 accesses the copying machine 5. FIG. 16A shows a data format at the time of Read processing. From the management device 1 to the communication control device 4, a model number 90 and a serial number 91 of the target copying machine 5, followed by a read request code 103 indicating a read process and an item code 104 for performing a read. It The transmission from the communication control device 4 to the copying machine 5 is performed with the model number 90 and serial number 91 fields removed. Receiving this data, the copying machine 5 transmits the requested read data 105 to the Rea.
It is transmitted to the communication control device 4 together with the d response code 106. Then, in the communication control device 4, the model number 90 and the serial number 91 are added again and the management device 1 is added.
Send data to. FIG. 16B shows a configuration example of the data format at the time of Write processing. Copying device 5 from management device 1 via communication control device 4
In the communication to the destination, write data 107 for writing
Is added and sent together with the write request code 108. In the communication from the copying machine 5 to the management apparatus 1, the write data 109 actually written in the copying machine 5 is written.
e Sent with the response code 110. In the normal case, the write data 107 received by the copying machine 5 and the write data 109 transmitted by the copying machine 5 match, but if the received data is out of the valid range, the data is rounded to the boundary value. May be written, and in such cases they do not match. Figure 1
6C shows an example of a data format configuration at the time of execute processing. Management device 1 to copier 5
In the communication toward the destination, when the operation target cannot be made only by the item code 104, the operation content supplement code 111 for supplementing the operation content is added and sent together with the Execute request code 112. Then, the copying machine 5 that has executed the requested operation sets the operation result information code 113 to Exec.
It is transmitted to the management device 1 side together with the ute response code 114.

FIG. 17 shows an example of the structure of the data format when the management device 1 accesses the communication control device 4. FIG. 17A shows the Read process, FIG.
Write processing of 7 (b), Execu of FIG. 17 (c)
te processing, and in any case, the data format is almost the same as when accessing the copying machine 5 of FIG. 16 described above, but here, instead of the model number 90 and the serial number 91, the communication control device 4 is used. A communication control device code 115 is provided. FIG.
Shows an example of a data format configuration when the communication control device 4 accesses the copying machine 5. This process has the same configuration as the data format between the communication control device 4 and the copying machine 5 in the Read processing when the copying machine 5 is accessed from the management apparatus 1 shown in FIG. In this case, the copying machine 5 does not need to distinguish between the access from the management device 1 and the access from the communication control device 4, and can handle the same.

The operation of the remote notification will be described based on the configuration of the data parameters and data format as shown in FIGS. 14 to 18 described above. Now, in the data format shown in FIG. 15, a notification reason code 97 is added to the data from the copying machine 5 and sent. The communication control device 4 identifies the notification reason code 97 and classifies it into the following contents.

1. Data from the remote notification key (b) 2. Data due to self-diagnosis abnormality 3. Data from advance warning 4. Data by Total Counter Value Then, the data thus classified is stored in the communication control device 4, and the telephone number 93 to be notified in the parameters of FIG. 14 corresponding to these data is selected and selected. Send to the specified number. In this case, centralized management can be performed by making the report destination telephone numbers 93 of the classification destinations the same, and management can be performed at individual locations by making them separate. In the configuration of FIG. 1, there is only one management device 1, but in actual work, the management device installed in another place is used to manage the number of copies and the service sensor is used for machine repair. You can go.

Next, the operation of the remote notification control of the copying machine 5 will be described with reference to the flowcharts of FIGS. First, FIG. 19 shows a state of notification control of the copying machine 5. Whether the remote notification key (b) is pressed when the communication permission switch 30 (see FIG. 4) is on,
Judgment is made as to whether the self-diagnosis function has detected an anomaly or if a warning is required in advance.If remote notification is required, the remote notification key is used to process the remote notification and the self-diagnosis error. Performs remote notification processing and remote notification processing with advance warning. 20 to 22
Shows the contents of each of the remote notification processes.

FIG. 20 shows the remote notification key (b) of the copying machine 5.
Fig. 7 shows a state of control of remote notification by. Remote notification data is transmitted to the communication control device 4 by the remote notification key (b). When the communication cannot be performed normally due to no response from the communication control device 4, a message to that effect is displayed on the operation unit 31 to notify the user. When the data is normally transmitted to the communication control device 4, the timer for time-out determination is reset and the communication result report from the communication control device 4 is waited for. In this example, the timeout time is set to 3 minutes, and if the notification result is not received within 3 minutes, it is timed out and the notification of the notification failure is displayed on the operation unit 31.
If you receive a report result report within the timeout period,
If the content of the report is a report success, the fact that the report is completed is displayed, and if it is a failure, a message to that effect is displayed.

FIG. 21 shows how remote control is controlled by the self-diagnosis abnormality of the copying machine 5. It is the same as the remote notification by the remote notification key (b), except that the data transmitted to the communication control device 4 is the data due to the self-judgment abnormality and the timeout time is 20 minutes. FIG. 22 shows how remote control is controlled by the copier 5 based on the advance report. It waits for transmission of remote notification data to the communication control device 4 by advance warning.

Next, the operation of the copying machine 5 when accessed by the communication control device 4 will be described with reference to FIGS. FIG. 23 shows the overall flow of the operation. Now, when the communication permission switch 30 is turned on, when there is received data in the communication interface unit 28, the received data is received and the processing requested by the first field is judged to determine which of Read processing, Write processing, and Execute processing. Or processing. If it is neither code, return an error code.
FIG. 24 shows a state of Read processing. If the item code received by the copying machine 5 is correct, the requested data is transmitted, and if not, an error code is returned. FIG. 25 shows a state of the Write process. If the received item code is not correct, an error code is returned. If the item code is correct, it is checked whether the written value is within the valid range. If it is within the valid range, the received data value is written as it is. If it is outside the valid range, determine whether it is possible to write data by rounding the data to the boundary value of the valid range for each item code. If the data can be rounded and written, write the boundary value. Put in. For example, if the effect of rewriting is large even within the effective range, such as the setting of the fixing temperature, or the telephone number of a service center whose value does not make sense, rounding to the boundary value is prohibited and automatic reset is performed. Items such as time that do not affect the image quality allow rounding to the boundary value for convenience. Further, when it is desired to make the auto reset time as long as possible, the maximum value is automatically selected on the copying machine 5 side by setting the written value to the maximum value with the full number of digits. FIG. 26 shows Execut
7 illustrates a state of e processing. If the received item code is incorrect, an error code will be returned. If the item code is correct, it is determined whether the action content supplement is required for the item, and if not, the designated action is performed and the action result information is returned. If the operation content supplement is an item that requires supplementary information, the operation is performed according to the supplemented information. However, if the operation content supplement is data outside the valid range, an error code is transmitted and the process ends.

Next, the communication control device 4 and the copying machine 5
A communication procedure with the communication device will be described with reference to FIGS. 27 to 32. FIG. 27 shows a communication sequence in an idle state when five copying machines 5 are connected to the communication control device 4. The communication control device 4 executes a polling cycle in which a polling address of each copying machine 5 is used to sequentially transmit a polling sequence. The copying machine 5 polled with the polling address sends a negative response to the transmission control device 4 to the communication control device 4. The communication control device 4 repeats the polling cycle when there is no other communication processing. FIG. 28
Shows an example in the case where the copy machine 5 of the address has a transmission text of a remote notification. After the polling sale at the address of the own machine, the transmission text is sent out on the RS-485 line. FIG. 29 shows an example of the case where the communication control device 4 transmits the text of the notification result report to the copying machine 5 of the address. After the current polling is completed, the selecting sequence is transmitted by using the selective address of the target copying machine 5, and the text is transmitted to the copying machine 5. After sending the text, the original polling cycle is resumed.

FIG. 30 shows a communication sequence between the communication control device 4 and the copying machine 5 when the management device 1 or the communication control device 4 accesses the copying machine 5 of the address. The communication control device 4 selectively selects the target copying machine 5, and requests Read, Write.
Send the text of either the request or the Execute request. Immediately after this, the same copying machine 5 is polled and a response to the request is received. In reality, this sequence is inserted during the polling cycle shown in FIG.

FIG. 31 shows an example of the regular data processing, that is, a transfer sequence of the counter value of the total number of copies, which is performed periodically. Now, communication control device 4
When the collection time of the counter value of the total number of copies is reached, a selecting cycle for sequentially performing selection for the copying machines 5 at the addresses is inserted between polling cycles. When there is a response during the selecting cycle, immediately after that, the same copying machine 5 is polled to receive data, and in the next selecting cycle, the copying machine 5 is not selected. To do so. Here, in the first selecting cycle, there is a response from the copying machine 5 of the address ,, and in the next selecting cycle, the selecting is performed only to the copying machine 5 of the address where the previous data could not be received. There is. Then, in the next selecting cycle, the reception of the data of all the copying machines 5 is completed,
It returns to the state shown in FIG. 27 in which only the normal polling cycle is performed.

FIG. 32 shows another example of the scheduled data processing. When the collection time of the counter value of the total number of copies is reached, selecting is performed instead of polling at the timing of polling each copying machine 5. Immediately after that, the copying machine 5 that responds to the selecting is polled to receive the data.
The first cycle from the address to the copying machine 5 immediately after the time of collecting the counter value of the total number of copies is similar to that of FIG. 31, but the polling cycle is not inserted next. In the second cycle, the copying machine 5 which has already received the data is polled, and the copying machine 5 which cannot receive the data is again selected for the counter value request. When the data of all the copying machines 5 can be received, the normal state of performing only polling is restored. Here, as in the case of FIG. 31, a response is first received from the copying machine 5 of the address ,, and the reception of the data of the copying machine 5 of the address among the copying machines 5 that could not receive the previous data in the next cycle is completed. However, the data of all the copying machines 5 can be received in the next cycle.

Further, the following processing is further performed on the regular data processing as shown in the above two examples. When the date and time indicated by the parameter set in the communication control device 4 is reached, the call destination telephone number indicated by the parameter set in the communication control device 4 is called and the counter value of the total number of copies is reached. Is transmitted to the management device 1. However, if the host machine 8 side or the communication control device 4 side happens to have a power failure at the internally set date and time, or if the set date and time is set to a day with only a leap year, such as February 29, the total Some years can be processed by the counter and some years cannot be processed, which causes inconvenience in operation. Therefore, in the present system, as shown in FIG. 33, when the processing is not completed at the date and time indicated by the parameter, monitoring is subsequently performed and this operation is performed until the processing is completed. When there is no February 29, the processing is performed on March 1. Also, in this system,
Although the data of a plurality of copying machines 5 are controlled, the current copying machine 5 is highly functionalized by colorization, digitization, etc., and a total counter is connected to a plurality of copiers 5 instead of one. Some devices may be connected, and up to three devices may be connected to this unit. At this time, when the data is sent to the host machine 8, if each counter is divided into individual copying machines 5 and sent to the host machine 8, an extra transmission cost will be incurred. Therefore, when there is data to be transmitted, they are collectively transmitted.

Finally, other functions of the communication control device 4 used in this embodiment will be described. When data transmission is performed using the public line 2, a communication fee is required depending on usage time, distance, and the like. At present, personal computer communication, which is often used, employs a system in which a line is connected each time communication is performed, and therefore, there is a drawback in that a basic charge is charged each time even for short communication. Therefore, the present apparatus is provided with a function of temporarily storing the data of each copying machine 5, a function of calling the other party, and the like. In this case, by providing the function of temporarily storing, it becomes possible for the communication control device 4 to collectively send the internal information that can be sent at a time. Further, as shown in FIG. 34, by providing a function of a calling process for making a self-call to the other party, when new data to be sent to the same destination comes when the particular destination is in the standby for re-call, It becomes possible to initialize the recalling number counter to increase the possibility of connecting with the other party.

As described above, in the management apparatus 1, the callee storage means for storing a plurality of callees and the specific data among the data sent from the copying machine 5 are stored in the callee storage. Table storing means for storing a table for distinguishing whether the data is to be sent to the calling destination stored in the means, and the data sent from the copying machine 5 are identified by the table stored in the table storing means to identify a predetermined destination. By providing the data identifying and transmitting means for sending the data to the copying machine 5, the management apparatus 1 can access the data of the copying machine 5 even when the power of the copying machine 5 is cut off. In this case, by transmitting the table stored in the table storage means in the management device 1 from the communication control device 4 by the table transmission means, it is possible to remotely read out the data for the maintenance contract which needs to be read out periodically. Moreover, it can be performed regardless of the power-on state of the copying machine 5.

Communication is provided by providing table initial value setting means for automatically setting a predetermined initial value to the table stored in the table storage means in the management apparatus 1 when electricity is first turned on to the management apparatus 1. Since the control device 4 automatically connects the line to the management device 1 to transmit data, it is not necessary to access from the management device 1, and by connecting the line from the communication control device 4 side, it is possible for the operator to It is also possible to connect the telephone 6 which cannot be directly accessed from the management device 1 due to extension exchange.

Since the table changing means for changing the table stored in the table storing means in the management device 1 via the communication control device 4 during transmission of the table is provided, the line connection of the communication control device 4 is made for each customer. It is possible to set the period of time, and it is possible to perform data transmission processing corresponding to the contract closing date for each customer. In addition, this can eliminate the concentration of data reception within the period,
Reception processing can be performed systematically.

When the table stored in the table storage means in the management apparatus 1 is changed, if there is data that has already been classified by the old table, the table is changed after all the old data is processed. Since the table changing means is provided, the management device 1 except the communication control device 4 which is difficult to connect the line from the management device 1 side, such as being connected to the telephone 6 whose extension is exchanged by the operator.
It is possible to perform processing such as connecting a line to receive data from the communication control device. Also, when calling from the communication control device 4, it is possible to reduce the possibility that the connection of the line becomes impossible due to the excessive processing capacity of the management device 1. Therefore, the management device 1 can more systematically perform the reception process.

When the table stored in the table storage means in the management apparatus 1 is changed, if there is data classified by the old table, the host machine 8 or the like should have the old data before changing the table. Data for automatically changing the table after notifying that the table is automatically changed after notification, or data for changing the table according to the instruction of the host machine 8 after notifying the host machine 8 before changing the table Post-notification table instruction changing means is provided, or if data is detected after the table is detected by the host machine 8, the data after detection is temporarily suspended during the period until the table is changed. Since we have set up a means for temporarily suspending collection,
Since the communication control device 4 which has not responded to the setting for receiving the specific data has no possibility of responding to the polling, the polling / setting efficiency for each communication control device 4 can be improved by eliminating meaningless polling. Therefore, the waiting time until the data transmission of the communication control device 4 waiting for the data transmission right can be shortened.
