DETAILED DESCRIPTION OF THE INVENTION No. 11-1999-- This invention relates to a copying machine management device that centrally manages a plurality of copying machines at one location.

Sumire Ushijutsu Traditionally, when jl - type copying machines are used by multiple departments, the value of copies (cumulative number of copies, etc.) has not been managed separately for each department. There is.

For example, in Japanese Patent Laid-Open No. 54-72057, which was filed by the present applicant and has already been published, there is a unique information indicating the department of use recorded on a portable information recording medium (magnetic card, etc.) distributed to each department of use. It is disclosed to recognize a code and to cumulatively store in a predetermined storage area of a data storage device characterized by the code the value of copies made in the department of use.

Also, Japanese Patent Application Laid-open No. 54-3539, also by the present applicant.
The publication discloses that a unique code indicating the department in use is set and input using a numeric keypad switch.

Nowadays, in the information age, the need for copying services is rapidly increasing in government offices and businesses.

In user organizations such as schools that have a large number of users, there are cases in which multiple copying machines are installed and any copying machine can be used by a large number of users or by a user department that is a group of specific users. Can be seen.

Even in this type of use of copying machines, it is necessary to comprehensively manage the value of copies made by each department (or user) using the copying machines, from the perspective of sharing the cost of copying among beneficiaries. There is.

However, in the conventionally proposed tIL-copying machine management device, the use value of each usage department made by the copying machine is only stored in the data storage device of each copying machine, and the above-mentioned copying If the conventional device is applied as is in the usage pattern of a group of machines, the use value information of each usage department will be dispersed to each copying machine, and the burden of human labor such as collecting and aggregating the information will be large. Moreover, this burden tends to increase as the number of copying machines increases and the number of departments using them increases.

Therefore, the present applicant further applied
As disclosed in the above publication, copy data for each department code is transmitted from each of a plurality of copiers to a management device, cumulatively added and stored as the number of copies for each department and on the copier side. This paper proposes a central control device for copying machines that allows stored data to be aggregated and displayed or printed out as needed.

However, since this device does not have a means for storing usage value information such as the number of copies per department and maintenance information for each type on the copying machine side, as the scale increases and the signal transmission path becomes longer, the accuracy due to noise etc. In some cases, the data may not be transmitted properly, or the storage data may be lost due to some reason on the management device side. In such cases, a problem arises in that the data cannot be re-collected.

In addition, since the operators of each copying machine and the management device cannot communicate with each other, it is inconvenient that in the event of a paper jam or malfunction, it is not possible to quickly make inquiries and respond to inquiries about what to do. Met.

Return to the main routine of FIG. 11 and proceed from 35-5TEP 15.

5TER' If it is determined that 5 is the display cart to O1, s
'The FPI+ executes the all-display routine shown in FIG. 13 and automatically displays the total number of sheets for each department on the display 34 sequentially from department code 001 every 4 seconds.

5TEP If it is determined to be a manual display card in 6, ST
I'! P]2, the program jumps to the manual display routine shown in FIG. 14, and each time the recall switch 41 is pressed, the total number of 41 sheets in the designated category is sequentially displayed on the display 34.

Further, by pressing the management switch 42, the use of the department code displayed at that time is prohibited.

In addition, the auto display card and manual display card have
Cards for daily totals, monthly evaluation cards, size-based force meter totals, and the like can be provided to display appropriate departmental sheet count data for each card.

If 5TEP 7 is determined as a clear card, 5TER
At step 13, the program jumps to the clear routine shown in FIG. 15 and presses the management switch 42 to clear (erase) all stored data.

If you want to clear only the data of the designated department, each time you press the recall switch 41, the designated department will be displayed one after another.
When the designated department you want to clear is displayed, press the management switch 4.
By pressing 2, the data for that designated department is cleared.

5TEP If it is determined to be a maintenance card at 8, 5
At TEP 14, the process jumps to the maintenance curtain shown in FIG. 16, and by pressing the management switch 42, the maintenance information of the copying machine is cleared, and by pressing the recall switch 41, the maintenance information is sequentially displayed on the display 34.

Returning to FIG. 11, in 5TEP 15, it is determined whether or not the inter-on call switch 43 has been pressed in order to notify the person monitoring the central management device of the occurrence of a paper jam or to perform an operation.

If it is determined that a call has been made, the process jumps to the interface on routine shown in FIG. 17 at 5TEP 16, and first checks whether the communication line 10 is in use by checking whether or not there is communication data as shown in FIG.゛0″
If so, it is determined that the terminal device is not in use, and the communication circuit 32 transmits the address (polling address) and ring tone of the terminal device to the central management device 9 via the communication line 10.

As a result, the central management device S immediately switches the selector switch 88 shown in FIG. 9 to the interface-on circuit 84 side if it is not communicating with another terminal device, or waits for the end of communication if it is currently communicating with another terminal device. The terminal number is displayed on the display 52 at the same time as the ring tone is emitted from the speaker 53.

When the operator on the central management device S side presses the call key 6 in FIG. 8 to respond, a response signal is input to the microcomputer 21 of the terminal device via the communication circuit 32. Therefore, it is determined that there is a response, and the communication line 10 is disconnected from the communication circuit 32 side by the relay 37 and connected to the interface-on circuit 33 side.

In this state, the users can talk to each other by switching between sending and receiving calls using the send/receive switch 40 on the terminal device side and the call key 6 on the central management device side.

Termination of a call due to intertab-on is determined by whether the button-on/button-off type call switch 43 is pressed again and turned off. If the call is terminated, the communication line 10 is returned to the communication circuit 32 side and the process returns to the main routine. do.

Also, after turning on the call switch 43 and making a call,
It may be possible to automatically return to the communication circuit side after a set time of ~3 minutes, thereby preventing forgetting to switch. If you cannot make a call within the set time, just press the call switch again.

On the central management device side, when the call ends, the operator calls the call key (in this case, it serves as the end key).
By pressing , the CPU 70 in FIG. 9 determines that the call has ended, and returns the selector switch 88 to the state shown in the drawing by means of a relay (not shown).

The communication line 10 is connected to the communication circuit 83 side.

Returning to the main routine of FIG. 11, in 5TEP 17, the start bit of the communication data from the central management unit received by the communication circuit 32 is checked by the logic level of the signal applied to the microcomputer 21.

The communication data (FIG. 10) is defined such that the header code data includes a start bit that lasts for a determined time at a certain logic level (eg, level ``1'').

If it is determined that this start bit exists, 5 TEP
The received data following the start bit at 1B is sent to the microcomputer 21.
The data is stored at a predetermined allocated address in the internal RAM of .

In 5TEP 19, it is determined whether the number data (polling address) of the terminal device included in the stored received data matches. If they match, the instruction code of the received data is sequentially determined in the following 5TEP 20 to 29. and process it. However, if the terminal numbers do not match, 5TEP
Return to 1.

Note that the instruction code is assigned as a binary code depending on the instruction.

5TEEP If it is determined that the instruction is ADS at 20, 5TEEP
At step 30, jump to the all data transmission routine shown in FIG.
Send all data sequentially.

In FIG. 18, it is determined in 5TEP 301 and 302 whether daily total number data is aggregated or monthly total number data is aggregated.

Daily accounting 2 policy accounting is assigned as a binary code in the sub-instruction code (see Figure 10) following ADS.

5TEP 304 to 308 are the daily accounting data sending flow, and in 5TEP 304, the department code ro is first sent.
It checks whether the oIJ data is zero, and if it is zero, the next department code "002" is checked in order to shorten the transmission time.

Since the data of the department code rooIJ is not zero, the 5TEP 305 sends the daily total number data to the central management device by communication data.

5TEP 306 checks whether the department code is the end of the setting code, and if it is not the end, 5TEP 307 increments the department code, and 5TEP 304 to 30
7 is repeated to send out the daily total number data of the next department code.

5TEP If the department code ends with 306, 5TE
Delete the counter (memory) of the daily sheet count data with P308 4
U-, send the completion code at 5TEP 316 and return to the 11th
Return to the main routine shown in the figure.

Next, policy data aggregation will be explained.

Similar to 5TEP 304, 5TEP 309 checks whether the policy data for each department code is zero, and if it is not zero, 5TEP 310 sends out the monthly total number data of the corresponding code. If the 5TEP 311 is on the size-specific collection side, the mode is checked and data of each size is transmitted sequentially.

5TEP 313.314 is the same as 5TEP 306 and 307 above. Finally, 5TEP 315 sends out the total number of copies from the copying machine, and 5TEP 316 sends a completion code.

Errors in each data are prevented by providing a parity check code for each data. Although not shown, if there is an error, a code for retransmission is sent and processed.

When it is determined that the instruction is DDS at 5TEP 21 in FIG. 11,
At 5TEP 31, it jumps to the routine to send the data of the specified department, but at 5TEP 304~308, 309~ in Figure 18.
Since it is the same as 315, illustration is omitted.

5TEP If 22 determines that it is an instruction ADC, 5TEP
At step 32, the program jumps to the routine for erasing all data shown in FIG. 1S.

Then, the execution timing code is sent to the central management device, and key operations on the central management device (for example, press r987 with the numeric keypad 56)
After checking the arrival of the execution code (by pressing Enter key 59 after J is input), the data in all sections of the memory is erased. Then, it sends a completion code to the central management device and returns to the main routine.

5TEP If 23 determines that the instruction is DDC, 5TEP
At step 33, the flow jumps to a routine for erasing data only for the designated department, but since the process is the same as the flowchart of FIG. 1S except for specifying the department, illustration thereof will be omitted.

5TEP When it is determined that the instruction is All0LD at 24, 5T
At EP 34, the program jumps to a routine that prohibits the use of all codes, and even normal cards are disabled in order to prohibit use of the copying machine by all department codes.

5TEP If 25 determines the instruction DHOLD, 5TE
At P35, the program jumps to the routine for prohibiting the use of the specified code, and prohibits department power 43-. This prohibition is performed by setting a logic "1" level to the first bit of the address corresponding to the department code of the memory.

5TEP 26 instructions vSED is judged, 5TEP
At 36, jump to the code usage ban release routine, and at 5TE
Remove the prohibition on P34 or 35. That is, the first bit of the address corresponding to the department code prohibited in the memory is set to the logic "o" level.

5TEP If 27 determines that the instruction is DRX, 5TEP
At step 37, the process jumps to a routine for displaying received data, and while the copying machine is in use, commands from the central management unit (for example, time, guidance when a jam occurs, etc.) are received and displayed on the display 34.

If it is determined in 5TEP 28 that it is a life device, the process jumps to the interface call routine in 5TEP 38, and in response to the interface call from the central management device, the communication line 1 is
0 to the interface-on circuit 33 side.

If 5TEP 29 determines that the instruction is MDS, 5TEI)
3944- jumps to the machine data transmission routine, and transmits machine data indicating the status of the copier, such as in use, jam occurrence, size in use, serviceman call, etc. in response to polling from the central management unit at set times. do.

The display contents 56- in the figure indicate whether the total is by department or on the terminal side, and when it is by department, it is displayed as "Bumon", and when it is on the terminal side, it is displayed as "Tanmatsu". ■ is the department code or terminal code being printed, and ■ is the total content specification code.

■ is a summary item, "Nirakei Tsukikei Kukankei"
, ``Tsukikei Keihi J, ``Tsukikei A3A4 84
B5J etc. are displayed.

In the case of a designated department or designated terminal tally, as shown in FIG. The content of the tally is displayed by the printer 51.

In the figure, the display contents ■ is the display of "Bumon" or "Tanmatsu", the ■ is the display of the total content, and the daily total is "D".

The monthly total is displayed as "M" and the 2-section total is displayed as rWJ. ■ is the department code or terminal code, ■ is the total number of sheets, and ■ is the total expense.

Next, the manual concentrating operation of the terminal state will be explained with reference to FIG.

First, press the status key 64 in Fig. 8.
"Tanmatsu Code" will be displayed and a guide display will appear on the right side of the screen. If you enter the terminal code of the terminal device you wish to receive using the numeric keypad 56 and press the ENT key 59, the copying machine stored in the designated terminal device will be displayed. Machine data (maintenance data) indicating the state of the machine (terminal state) is collected and displayed. Then, by pressing the print key 61, the contents are printed out.

By sequentially inputting each terminal code and repeating the above operations, all the machine data of each terminal device can be totaled, and by pressing the end key 57, the process ends.

The data is printed in print order 1~.

−ζ0− be able to.

Finally, the operation of interon call and the CPU at that time
The functions of 70 will be explained with reference to the flow diagram of FIG.

This is an operation and function when trying to make a call by specifying a specific terminal device from the central management device side.
When the call key shown in the figure is pressed on the 6th, the business name will be displayed on the display 52, and the guide ``r-1-J'' will be displayed on the right side at the position where the designated terminal address (number) is displayed. .

Therefore, when you input and specify a terminal code using the numeric keypad 56 in Figure 8, that code is displayed on the guide display section of the display 52 (Figure 40 shows the case where "001" is specified). .

When you press the ENTER key - 5th, the code is CPU7 in Figure S.
Settings are stored in [].

Therefore, the CPU 70 determines whether the communication line 10 is in use or not based on the presence or absence of communication data, and if it is not in use, transmits the address and ring tone of the set calling terminal to the communication circuit 83.
After transmitting the data, the communication line 10 is switched to the interface circuit 84 side using the changeover switch 88 in FIG.

At this time, the terminal device whose address corresponds to the address of the calling terminal sent from the central management device 9 immediately receives,
Switch the changeover switch 38 in Fig. 4 to turn the communication circuit 10 into an interface-on circuit! 13 side, and the ring tone is produced by the speaker 3.

Thereby, it becomes possible to communicate with each other between the central management device side and the designated terminal device side.

When the call ends, press the call key 6th again in Figure 8 (at this time, the call key 6th serves as the end key).
The CPU 7Q determines that the call is over, turns off the display of the calling terminal code, and presses the selector switch 88.
to the state shown in FIG. 9 and connect the communication line 10 to the communication circuit 8.
Connect to side 3.

On the other hand, on the terminal device side, when the operator turns on and off the call switch 43 shown in FIG.
At this time, the call switch 43 serves as an end switch)
, the microcomputer 21 determines that the call is over, turns off the relay 37, and switches the switch! 18 is returned to the state shown in FIG. 4, and the communication line 10 is connected to the communication circuit 32 side.

This enables data communication between the central management device and the terminal device again.

Example - U.S. As described above, according to the present invention, a large number of copying machines constituting a group of copying machines can be easily centrally managed in one place, and the central management device can control the copying machines as needed. It is possible to obtain aggregated data showing the copy value by department, the number of copies per copy on the copying machine side, etc.

In addition, since the data for each copying machine is stored in the terminal device attached to each copying machine, the data can be transmitted from the central management unit as many times as necessary, and there is no need to worry. There is no risk of data loss due to data loss or reception errors.

Furthermore, since each copying machine and the central management device can communicate with each other as necessary, inquiries, responses, and instructions can be sent in the event of a paper jam or malfunction in the copying machine. It can be done quickly and is extremely convenient.
