The operation is thus improved.

Description

TECHNICAL FIELD The present invention relates to an apparatus for managing the amount of equipment used, such as the number of copies made by a copying machine and the number of facsimile communications, using a recording medium on which predetermined data is recorded.

Prior Art Conventionally, as a means for managing, for example, the number of copies per department, with one department as one unit, a mechanical counter (so-called key counter) was provided for each department, and this counter was used when using a copying machine. There was a device that enabled copying operations by being inserted into a copying device, and also registered the number of copies made in a counter.

However, if the administrator wants to know the number of copies,
The counters that display the number of copies are kept by department, so the administrator has to visit each department from time to time to check the number of copies displayed on the counter, which requires a lot of effort and tabulation. The major drawback was that the work was troublesome. Furthermore, since the counter itself is relatively expensive, it is not economically desirable in the case of multi-department use, and it also has the disadvantage of being less convenient to carry in terms of shape and weight.

From this point of view, in recent years, when using equipment, a department card with a department code recorded on it is inserted into the device to enable operation, and the device is also equipped with a memory that stores the usage amount by department. If the administrator wants to keep track of the amount of equipment used by all departments, the amount of equipment used by each department can be recorded by inserting a card with a predetermined function code into the device. A device management device configured to display the amount and total amount used has been proposed.

In such a device, when the administrator wants to grasp the amount of usage in all departments, there is a known technology that displays the amount of usage by inserting a special card or inputting a special key, for example. . However, once the display of the usage amount is started using the above method, there is a problem in that the copying machine cannot be used until all usage data for all departments is displayed.

Purpose The present invention has been made in view of the above points, and its purpose is to provide a management device for a device that can switch from a mode to another mode while operating in a mode that displays data related to usage. It is about providing.

9 to 16.18 and 20.22 to 24 are flowcharts showing embodiments of the present invention.

A detailed explanation will be given below.

First, as shown in Fig. 9, when the power is turned on, the
A voltage check routine for the backup power supply 12 of RAMI 1 is executed (Step 500), and it is determined whether a card is inserted. This is because in configurations in which power is supplied from the device itself, such as a copying machine, it cannot be determined even if a card is inserted by the user when the power is turned off, so when the power is turned on, it is always determined whether a card is inserted or not. In this case, it is necessary to have the card inserted again. Therefore, in step 10 of FIG. 9, L for card data A is
Turn on ED31 and B LED33, and turn on the photo sensor 30.
Start detection of ゜32, and LE each at 5tep20
It is determined whether the signal card data A signal and B signal from the photosensors 30 and 32 facing D are on/off. If a card is inserted here, the display will show r-E-
J is displayed to prompt the user to reinsert the card. And always 5te
The signal is monitored based on the pH, and only when both are turned on, it is determined that the card has been pulled out, and the no card display r-p-j is displayed at 5tep13, the check is finished, and 5tap
Proceed to step 14.

If the card is inserted, run the voltage check routine for the backup power supply 12 of 5-RAM 1l.
ep 600), proceed to Step 14. 5tap 14 is for determining the type of inserted card, and if no card is inserted, r-P-J is displayed on the display section 6 (S
t e p 14) When inserted, the card data is read, and based on the read data, it is determined whether it is a management card or a department card (Step 5).
, unit price setting mode (S t e p 200), upper limit setting mode (St
ep300), erase mode (Step 400) is executed, and the latter has data from 1 to 200, and department mode (Step 100) is executed (
Step 20) If there is an error in card insertion, r-E E-J will be displayed on the display section 6 (Step 20).
-6)- Next, a detailed explanation will be given of card data reading in 5rep14 using the explanatory diagram of FIG. 7 and the flowcharts of FIGS. 1O to 13.

In FIG. 7, the card is inserted in the direction of the arrow, and the card has holes corresponding to the start pattern, card data, and stop pattern, which are detected by the card data A/B signal. In particular, in this embodiment, the start pattern and stop pattern are always different patterns, and if they are not detected in a predetermined order, reading of card data is canceled. In the flowchart in Figure 10, first step 2
0 detects the start pattern described later, and if it is detected, reads the data from step 21 to step 25. To avoid errors, data reading is performed only when the card is inserted within a certain speed range. However, in other cases, an error is displayed and the data is canceled.

That is, at 5tPe21, the "data cancel timer" is used to cancel the card insertion speed that is too fast, and at 5tep22, the "data out timer" is used to cancel the card insertion speed that is too slow. Perform data detection.If data cannot be detected even after the timer ends in 5tep22, 5tep
p23 displays r-E-J, prompts the user to reinsert the card, and waits for the card to be removed.

If data is detected, perform data detection/storage as described below in 5
This is done in step24, and then the data counter is incremented by 1 in 5rep25.

Data is read in 5 steps 21 to 26 until the counter reaches 8, that is, until 8 bits of card data are completed.

Then, in step 526, stop pattern detection, which will be described later, is performed, and if the process ends normally, reading of the card data ends.

FIG. 11 is a detailed explanation flow of start pattern detection, and the start pattern shown in FIG. 7 is detected as follows. First, 5tep20-1 confirms that the card data ■ signals are both on, that is, the card has not been inserted yet, and then 5tep20-2 confirms that [Yes],
(Both signals are off, that is, the tip of the card is inserted, and then 5tep20-3 indicates that the
Only the signal was turned on. That is, it is recognized in the order that the hole on the 0 signal side of the card has been detected. 5te here
If something other than the above is detected at p20-3, it is not recognized as a start pattern and an error is generated.

Next, FIG. 12 is a detailed explanation flow of data detection. 5
In step 24-1, detect the position of the card without a hole,
At step 24-2, it is detected whether the card data ■ signal or ■ signal is off, that is, whether it is on the hole side or the ■ side, and at step 24-3, the ■ side data is set to 1 on the O20 side. The data is stored in the bits of the card data that correspond to the contents of the counter.

In other words, in the case of Figure 7, the data is 01010110 days.
It becomes 86 in O base.

In FIG. 13, the stop pattern detection is as follows:
5tep 26-1 detects no hole, 26-2 detects a hole only on the side, 26-3 detects no hole, 26-4 detects [Yes], both 0 detects a hole, 26-5 detects no hole The stop pattern is recognized in the order of detection. 5 steps here
If there is any other detection at 26-2 and 26-4, it will not be recognized as a stop pattern and will be treated as an error.

Next, processing in each mode will be explained.

FIG. 14 is a flowchart showing details of processing contents in department mode.

In this mode, each time a copy is made, the total number of copies corresponding to the department card number is increased by 1, and at the same time the RAM in the microcomputer IO is
This is the mode in which the data is stored in the .

At 5teplOO-1, the relay coil 27 is turned on by a signal from the terminal 03 of the microcomputer 10, and its contact 26 is turned on to permit the copying machine main body to copy.

In 5tep100-2, pictogram display mark 7-1.7-
4 and indicate the "#" mark and the "Evening" mark respectively. (In Step-3, set the sono card data as department data and the corresponding [number of copies])
and [upper limit number of sheets] are backed up and read from the stored 5-RAM.

At 5teplOO-4, the C card data (department number) and the cumulative number of copies for that department are displayed on the number display section 6.0 Next, at 5teplOO-5, a pulse is output every time the copying machine makes a copy. Number of sheets count pulse signal〕
, and add 1 to the above-mentioned [number of copies] by outputting a signal, and at the same time write and save the [number of copies] in the above-mentioned 5-RAM, and then return to 5tep100-4.
The number is displayed on the number display section 6.

On the other hand, in 5TEP100-6, while the [sheet count pulse signal] is not output, the [number of copies per copy] is the [upper limit number of copies].
If this is the case, the relay coil 27 is turned off, copying is prohibited, and at the same time the display on the number display section 6 is blinked to notify the user that the number of copies has reached the upper limit. Furthermore, the 5tpe100-7 constantly checks whether a card is inserted, and if the user removes the card during copying, that is, if the user wants to interrupt copying, it immediately turns off the relay coil 27, prohibits copying, and The display on the display section 6 is closed to (-P-) to notify that there is no card.

FIGS. 15 and 16 are flowcharts showing in detail the processing contents of the unit price setting mode.

As mentioned above, this mode is used to set the unit price for each copy, and when the unit price setting card is inserted, the data (201 in this embodiment) of the card is read and this mode is started.

First, in step 200-1, change the display of number display section 6 to r---
-J, and at the same time read unit price setting data from S-RAMII. At this time, if nothing is set, rO, 01J
Φ key 8-1 at 0th step 100-2 where is read
Check whether or not is pressed, and the emoji display mark 7-
2. Turn on 7-3 and instruct the "@ mark" and "(mark)" and display the unit price setting data as shown in Fig. 17 (a). Then, in 5tep 200-3, press key 8.
Check whether -1 to 8-3 have been pressed. When the Φ key 8-1 is pressed, the unit price data is counted up to ten.

When the e key 8-2 is pressed, the count is increased to -.

Figure 16 shows the details of the counting method, but if the unit price data is from 0.01 to 9.99, it should be counted in increments of 0.01 (Figure 17 (b)), 9.99 +0
．． At 01, the display is switched to 10.0 (Figure 17 (C)), and from 10.0 to 60.0 it is counted in increments of 0.1 (Figure 17 (d)). This is because up to 0.1 yen is sufficient in Japan, but up to 0.018 yen is required in the United States, for example.

Then, when the Roro [mouth ■ key 8-3 is pressed, the unit price setting is confirmed, the display is turned off after 5 step 200-4, the data for which 1 sand diameter has been confirmed is displayed on the number display section 6, and at the same time the S- Write to RAMII to exit this mode.

FIG. 18 is a flowchart showing in detail the processing contents of the upper limit setting mode.

As mentioned above, this is a mode that sets the upper limit for the number of copies for a specific department, and in particular, it is a mode that can prohibit or cancel the use of a specific department, and when the upper limit setting card is inserted, the data of that card is (202 in this example)
Read and start upper limit setting mode.

First, in step 300-1, change the display of number display section 6 to r---
-J, and at the same time, each department data (
1 to 200), and the initial value of the apparatus is set to the maximum value (100,000 sheets) for each department.

Next, in 5tep300-2, Φ key 8-1 or e key 8-
When 2 is pressed, (department data) and [upper limit data]
is displayed on the number display section 6.

Then, in step 300-3, the pictograph display mark 7-1 is blinked to instruct the "# mark" to blink, and the pictograph display mark 7-4 is lit to indicate the "(mark)" (19th step 300-3).
(a), this state is maintained for 2 seconds until any of the keys 8-1 to 8-3 is pressed. When the mark 7-1 indicating the "# mark" is flashing, it is the department mode, and when the key is pressed, the e key 8-1 changes the [department code] by +1. With the e key 8-2, -1 is displayed.
)(c)), and repeats every time a key is input (Step 30).
0-4).

Also, if no key input is performed, 5te after the aforementioned 2 seconds has elapsed.
Proceed to p300-5, and this time mark 7-4, which indicates "(mark"), blinks, and mark 7-, which indicates "# mark"
1 (Fig. 19 (d)), continue this state for 2 seconds until the key is pressed, and after 2 seconds, turn on 5tep300-
Return to 3. When the mark 7-4 indicated by the "θ mark" is blinking, it is the upper limit setting mode, and when the key is pressed, the e key 8-1 sets the [upper limit data] by +1000.
, e key 8-2 displays -100OL (Fig. 19(e), (f)), and this is repeated for each key input thereafter (St
ep300-6), at this time, by setting [upper limit data] to 0 or less than the current cumulative number of sheets used, copying for that department can be prohibited.

Also, when the ENTER key 8-3 is pressed, the upper limit data is confirmed, and the display is temporarily turned off at 5Lep300-7.
The confirmed sand diameter [department data] and [upper limit data] are displayed on the number display section 6, and the marks 7-1 and 7-4 indicating the "# mark" and "θ mark" are lit, and at the same time the S-R
Write to AMII and exit this mode.

FIG. 20 is a flowchart showing details of the processing contents of the erase mode. This is a mode that clears all the cumulative copy number data for departments 1 to 200 stored in the 5-RAM11 to 0, and is not cleared in the upper limit setting mode or unit price setting mode.

First, (-------) is displayed on the number display section 6, and -(S
Step 400-1), Roro Nishiko] By pressing Loki-8-3 (Step 400-2) the display will turn off -H.

Clear the number data in 0 to 0, and when finished, 5tep
At 400-5, the number display section 6 "00...OOJ" is displayed to notify the completion of erasure.This makes it possible to easily clear the number of sheets data.

Also, by using an erasing card to do this, the reliability of management can be improved because the user cannot erase without this card.

Next, the display form of the pictogram display marks 7-1 to 7-4 and the display contents of the number display section 6 will be explained in detail with reference to FIGS. 21 and 22.

Figure 21 (a) shows the display format when the unit price setting card (Figure 1 (C)) is inserted, and the unit price (@) per sheet (9).
, and the display on the number display section 6 at that time indicates the value.

Further, FIGS. 21(b) to (e) show the display form when the ENTER switch 8-3 (FIG. 4) is pressed when no card is inserted. The process will be further explained below with reference to the flowchart shown in FIG. When no card is inserted, the number display section 6 shows (-P-). From this state, press ENTER switch 8-3.
When is pressed (Step 700-1), (---
