Abstract

PURPOSE:To rapidly obtain collected and totalized data by storing use value information, such as a number of copies sorted into each use division at the terminal of each copying machine, enabling mutual communication between the central controller and the controller of each copying machine, of the machine groups at any time, and shortening times for collecting accumulated stored data. CONSTITUTION:The terminals 5, 6, 7, 8 attached to copying machines 1, 2, 3, 4 are connected to a central controller through communication lines 10 by the multidrop system, and replies to an instruction signal contained in transmitting data from the controller 9 only when the polling address contained in said transmitting data coincides with a specified independent address of each terminal 5-8, and executes transmission of the data, etc. The controller 9 is directly connected with each terminal 5-8 directly without using communication lines 10, and transmits the polling address, and by these means it can communicate separately with each terminal, too. Data modulation for transmitting the data uses the PZ system through DC transmission for sending them, but uses differential detection system for receiving them. The application of this system facilitates centralization of control, and automatical collection and totalization of copying value data.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a copying machine management device that centrally manages a plurality of copying machines at one location.

BACKGROUND OF THE INVENTION Conventionally, when a single copying machine is used by a plurality of departments, the value of copies (cumulative number of copies, etc.) has been classified and managed for each department.

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.

Further, Japanese Patent Laid-Open No. 54-3539, also filed by the present applicant, discloses setting and inputting a unique code indicating the department in use 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 management device for a single copying machine that has been proposed in the past, only the usage value of each usage department made by that copying machine is 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, as disclosed in Japanese Unexamined Patent Application Publication No. 56-12652, the present applicant further transmitted copy data classified by department code from each of a plurality of copying machines to a management device, A central control device for a copying machine is proposed in which the number of copies is cumulatively added and stored, and the stored data can be aggregated and displayed or sent to the printer 1 as needed.

However, since this device does not have a means to store use value information such as the number of copies per department on each copying machine side, as the scale increases and the signal transmission path becomes longer, accurate transmission becomes impossible due to noise etc. In some cases, the storage data may be lost due to some reason on the management device side, but in such a case, the problem arises that the data cannot be re-collected. .

Also, if the terminal device of each copying machine were to store cumulative data such as one copy for each department.

A problem arises in that it takes time for the management device to collect and aggregate the data.

This invention was made in order to solve the problems caused by the conventional copying machine management device as described above. stores usage price information such as the number of copies per copy, and enables communication at any time with the management device that manages the group of copying machines;
Another object of the present invention is to shorten the time required for the management device to collect cumulative data such as the number of copies by department stored in each terminal device, thereby shortening the collection time.

In this specification, the term "copying machine" refers not only to general copying machines but also to machines having a copying function, such as facsimile machines and copying machines. In addition, "department" shall refer to any necessary division of management of a company's departments, groups, individuals, etc.

and check data. The actual data changes in length and size ff1) depending on the command.

Next, the operation of the terminal device will be explained with reference to operation flowcharts shown in FIGS. 11 to 1.

FIG. 11 shows the main routine that is cyclically repeated from power-on.

When the power is turned on, the standby state is displayed on the display 34 at S'rlEP 1, the insertion of the magnetic card 2 is checked at S1'EP 2, and when the magnetic card is inserted, 51'EP 3 is displayed. 5TEP determines whether the code read from the magnetic card is valid (not a prohibited department code), and if it is not valid, jumps to the error routine shown in FIG. 12 at 9 and displays an error on the display 64. If it is valid, then S'l'1EI) 4-8 determines whether it is a card for each function.

S'l'lEP 4 Te Division 7'J -F,! = Judgment route, 5TEP At 10, the program jumps to the copy routine shown in FIG. 12, issues a prohibition release signal S27 to the copying machine to cancel the copy prohibition, and displays the department code and the cumulative number of copies for that department. Then, the copy size signal S29 from the copy machine
After that, the departmental cumulative number counter and the size-specific number counter are incremented by the copying pulse 82B that arrives every time one copy is made, and the data is stored in the terminal data storage memory 22.

When the copying process is completed and the magnetic card 23 is removed,
Return to the main routine in Figure 11, and
Proceed from.

If S'l'EP 5 determines that it is O (-display car 1~), 5T1iP11 jumps to the auto display routine shown in Figure 16, and displays the cumulative number of 31 sheets for each department with the department code 001.
From then on, it is automatically displayed on the display 34 every 4 seconds.

If 5TIEP 6 determines that the manual display car is 1',
5 In TIEP 1.2, jump to the manual display routine shown in FIG. Prohibits the use of the displayed department code.

In addition, the O1 display car 1 (and the manual display card has a card for the 131 collection, a monthly A1 collection A1 car 1, a cart for each size policy collection, etc.) Appropriate departmental sheet count data can be displayed.

5 TEP 7 If it is judged as a clear card, ST
E PI 3 jumps to the clear routine shown in FIG. 15, and all stored data is cleared (erased) by pressing the management switch 42.

If Yang wants to clear only the data of the designated department, each time he presses 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.

If it is determined to be a maintenance card in Sl'lEP 8, the process jumps to the maintenance card shown in FIG. are sequentially displayed on the display 34.

Returning to FIG. 11, S]1]15 tells the person monitoring the central management device whether a paper jam has occurred or whether the inter-on call switch 43 has been pressed in order to delay the operation. judge.

If it is determined that a call is being made, the STI! IP16
Then, the process jumps to the inter-on routine shown in Fig. 17, and first checks whether the communication line 10 is in use or not according to the presence or absence of communication data shown in Fig. 10, and if the communication data is all 0.
'', 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 9 immediately switches the selector switch 88 shown in FIG. In other words, the ring tone is emitted from the speaker 5, and at the same time, the terminal number is displayed on the display 521'.

When the operator on the central management device S side presses the call key 68 in FIG. 8 to respond, a response signal is sent to the microcomputer 21 of the terminal device via the communication circuit 32. Once it is determined that there is a response, the relay 37 disconnects the communication line 10 from the communication circuit 32 side and connects it to the interface-on circuit 6 side.

In this state, the users can talk to each other without switching between sending and receiving calls using the send/receive switch 40 on the terminal device side and the call key 68 on the central management device side.

Termination of the call due to inter-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 46 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 presses the call key 6B (in this case, it serves as the end key).
By pressing , the CPU 70 in FIG. 9 determines that the call is over, and returns the changeover switch 88 to the state shown in the figure by a relay (not shown) to connect the communication line 10 to the communication circuit 8 side, as shown in FIG. 11. Return to main routine, 5TE
At P17, the start bit of the communication data received by the communication circuit 32 from the central management unit is checked by the logic level of the signal applied to the microcomputer 21.

The communication data (FIG. 10) is defined such that the hander code data includes a star 1-bit that lasts for a determined time at a certain logic level (eg, level "1").

If it is determined that this star 1-bit exists, the correction EP
At step 1.8, the received data following start pick 1 is stored at a predetermined allocated address in the internal RAM of the microcomputer 21.

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.

If it is determined that the instruction is ADS at S1'EP 20, 5 TEP
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 the collection MI of the daily sheet count data or the summary of the policy sheet count data. Daily accounting 7 policy accounting is the sub-instruction code following ADS (
(see Figure 10) and is assigned as a binary code.

5TEII 304 to 309 are the daily accounting data sending flow, and 5TEP 304.305 first checks whether the data of the specified department code is zero,
Data is transmitted only when the data is not zero, and data that is zero is not transmitted in order to shorten the transmission time.

5TEP 305 transmits the daily total number data cumulatively stored in the bit number area of the terminal data storage memory 22 to the communication circuit 32 when the ST[EP 304 (7) determination is No (7) (when the data is not zero). to send it to the central management device.

5TEP 306 checks whether the department code is the end of the setting code, and if it is not, 5TEI+ 307
5TEP 308 increments the department code and checks whether the new department code has been registered.

If the department code is registered, 5TEP304~
307 is repeated to send out the daily total sheet count data for that department. If it is not registered, return to 5TEP 307, increment the department code, and edit EP 3.
Check 08 again.

In order to check whether the department code is registered or not, it is now possible to register the department code used on the central management device side (for details on how to register, see the explanation of system settings using the central management device). ),
The M tt = data is transmitted to each terminal device, and the terminal device side receives it and, for example, corresponds to the registered department code 1 among the department codes in each department storage area of the terminal data storage memory 22. Flag only the areas that you want to use.

Therefore, in ST[EP 308, 5TEP 30
By determining whether this flag is set for the new department code incremented in
It is possible to check whether the department code is Hj.

Therefore, there is no problem even if the registered department codes are not consecutive and are discrete numbers.

After data transmission is completed, the counter of department code 1- is set to cell 1.
- If you set it to ro 00J and do not use this code, the daily data will be determined to be 20 at 5TEP 304 at first, so you will not be able to send the data and send it to S1'EP.
Proceeds to 306 and is not finished, so it is determined NO, 5T
In EP 307 the department code (- is incremented and r
Of the department codes that can be registered from oolJ to, for example, r25 (J), only the data of registered departments is transmitted, so the transmission time is shortened.

ST'EP 306 Te department D -+: If the card is finished, ST'EP309 displays the daily sheet count data counter (

The display contents ■ in the figure indicate that the terminal side tally is by department; 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,
■ is the aggregation content specification code.

■ is a summary item.
, "Tsukikei Keihi", "Tsukikei A3A4 B4
B5J etc. are displayed.

In the case of a designated department or designated terminal tally, as shown in FIG. 37, input the desired department code or terminal code using the numeric keypad 56, press the enter key 59, the tally details will be displayed, and then press the print key 61. and the contents of the tally are printed out by the printer 51.

In the figure, the display contents σ) are the display of "Bumon" or "Tanmatsu", ■ are the display of the total contents, and the daily total is "DJ.

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.

After the monthly totals have been tallied, the monthly total (cumulative) data of all terminals is cleared by the terminal clear operation shown in FIG.

Next, automatic counting operation will be explained with reference to FIGS. 38 to 40.

The CPU 70 in FIG. S checks whether the automatic aggregation counter has counted over on the 7th day of the timer in a main routine (not shown), and every time the count exceeds 1 (for example, every 1 minute or every 10 minutes). ), the main routine jumps to the automatic aggregation routine shown in Figure 38.

Then, in step ■, the time (1) of the clock 80 is read out,
In step ■, the automatic counting time (T) set in the RAM 72 by the operation shown in FIG. 25 is read, and in step ■, t=
'r or not is determined, and if NO, the automatic counting time has not come, so the process ends without doing anything and returns to the main routine.

If YES in step ■ (however, the difference between t and T within the timer countover interval of 7 days is equal),
In step (2), the month and day (D) of the clock 80 are read, and in step (2), the month and day (D') set in the RAM 72 are read.

This set date (D') is calculated from the section start date (SD) and section days (ND) set by the operation shown in Figure 26.
D' =SD+NDXn (n is the number of times of section aggregation) is the next section aggregation date, which is calculated by the CPU 7Q and stored in the RAM 72 when the section aggregation conditions are set and after the section aggregation is completed.

Then, in step 2, it is determined whether D=D' or not, and if no, in step 2, the process goes to the subroutine for daily accounting, and 1. If YES, go to step ① to go to the subroutine for section aggregation.

In the daily H1 totaling subroutine, as shown in FIG. 39, first, in step (2), the terminal address of the smallest registered machine number and the command code ADS for transmitting all data are transmitted.

Thereby, the department-specific (daily total) data sent from the designated terminal device according to the flow of all data transmission shown in FIG. Temporarily stored in the area.

Thereafter, in step (2), it is determined whether or not it is the final terminal, and if No, the terminal address is incremented by 1, and if it is not a registered terminal address (machine number), it is further incremented. If the terminal address is registered, step (1) and (2) are performed again to receive and store the data for each department of the terminal device at that address.

In this way, the terminal device with the highest registered machine number is sequentially called up to receive the departmental daily accounting data, and all of it is temporarily stored in the data area at the time of aggregation.

In this case, since only the terminal devices whose machine numbers are registered in advance, such as "double series", are sequentially called, the totaling time can be shortened.

If the answer is YES in step ■, refer to Table 2 (D) in step ■.
) to complete the daily accounting data for each terminal and each department, and display the data on the display 52 in step (■).
to be displayed.

Transfer this daily accounting data to the daily accounting data area shown in Table 2 (A) l using Step File, and step
Print out the daily budget table and return to the automatic aggregation routine shown in Figure 38.

In the section aggregation subroutine, as shown in FIG. 40 F7, in steps ■ to ■, only the terminal devices with registered machine numbers are sequentially called up in exactly the same way as in the case of daily accounting, and each department is called up. Receive separate shoulder/elbow (cumulative) data and store it in RAM.
72, Table 2 (D) & is temporarily stored in the area for data at the time of aggregation.

Then, in Step 2, the departmental totals Y1' to Ym' are calculated, and in Step 2, the totals for each section are stored in the cumulative data elina shown in Table 2 (C), and are calculated by terminal and at the time of the previous section aggregation. The cumulative total data for each department is subtracted from the corresponding data in Table 2 (D) to calculate the interval total.

In step ■, the interval total that is the result of this calculation is displayed, and in step ■, the interval total is placed in the interval total data area of Table 2 (C), and the data at the time of aggregation in Table 2 (D) is Table (B
) to the respective cumulative data areas.

Then, in step [phase], the interval table is printed out and the process returns to the automatic totaling routine of FIG.

Note that when the data of all terminal devices is cleared, the cumulative data of Table 2 CC) stored in the RAM 72 of the central management device is also cleared.

Next, the manual concentrating operation of the terminal state will be explained with reference to FIG. 68.

First, press the status key 64 in Figure 8.
"Tanmatsu Code" will be displayed and a guide 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 enter key 59, the copying machine stored in the specified 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 of the box will be 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.

Automatic collection is performed automatically according to the terminal collection conditions (collection start time and collection time interval) set in advance as described above, but in that case, as shown in FIG. Machine data from each terminal device is displayed as ``Jiyoutai Shuushin J'' (``-J flashes below ``rice''), and then ``Tanmatsu jiyoutai inji'' is displayed and the status of the terminal that received the information is displayed. data will be printed out.

Note that printing can be interrupted by pressing the end key 57.

Finally, the operation of interon call and the CPU at that time
The 700 function will be explained using 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 a guide display of r---J will be displayed on the right side at the position where the terminal designated address (number) is displayed. Ru.

Therefore, when you specify a terminal code using the numeric keypad 56 in Fig. 8, that code is displayed on the guide display section of the display 52 (Fig. 4 shows the case where rooIJ is specified). , when the enter key 59 is pressed, the setting for that code I is stored by the CPU 7[1 in FIG.

Therefore, the CPU 70 determines whether the communication line 1o 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 1o is switched to the interface circuit 84 side using the changeover switch 88 shown 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 receives it, and
Switch the changeover switch 38 shown in FIG.
Pronounce by 9.

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

When the call is finished, press the call key 6 in Fig. 8 again (at this time, the call key 69 serves as the end key).
When the CPU 70 determines that the call is over, it erases the display of the caller terminal code and returns the selector switch 88 to the state shown in FIG. 9 to connect the communication line 10 to the communication circuit 83 side.

On the other hand, on the terminal device side, after the call ends, the operator
When the call switch 43 shown in the figure is turned on and off (at this time, the call switch 46 serves as an end switch), the microcomputer 21 determines that the call is over and turns off the relay 37, and the changeover switch 38 is turned off as shown in FIG. Return to state and communication line 1o
Connect to the communication circuit 2 side.

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

As explained in "Example - 2 Roadside," according to the present invention, it is possible to easily centrally manage a large number of copying machines that make up a group of copying machines at one place, and the central management device can preset settings. At that time, it is possible to obtain aggregated data indicating the copy value, such as the number of copies made by the copying machine, by department of use, automatically or by operator's key operation as necessary.

At this time, only the data of the pre-registered department code of the terminal device with the number pre-registered in the central management device is transmitted and received and sent to the prefecture, so the total time is shortened.

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 as many times as necessary from the central management unit, preventing careless data transmission. There is no possibility of data loss due to data loss or reception errors.
