Description

TECHNICAL FIELD The present invention relates to an apparatus for managing equipment usage, 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.

BACKGROUND TECHNOLOGY Conventionally, each department is treated as one unit, and each department is provided with a mechanical counter (so-called key counter) as a means for managing, for example, the number of copies, and this counter is 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 a memory is installed inside the device to store the usage amount by department. If the administrator wants to keep track of the amount of equipment used by each department by storing the amount of equipment used by each department in memory, he or she can insert a card with a predetermined function code into the equipment and record the amount of equipment used by each department. A device management device configured to display device usage and total device usage has been proposed.

An example of this is a management device that uses an optical sensor to read, for example, departmental code data from an optical card having a clock hole and a data hole, thereby enabling the equipment to operate. With such devices, if an optical card is inserted into the management device and then pulled out midway through, incorrect data may be read. It is necessary to provide additional sensors, which has the disadvantage of complicating the configuration and increasing the cost of the device.

Purpose The present invention has been made in view of the above points, and its purpose is to provide a device management device that has a simple configuration, is inexpensive, and is capable of reading data with high reliability. .

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,
A voltage check routine for the AMII backup power supply 12 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, at step 510 in FIG. 9, the LED 31 for card data A and the LED 33 for card data B are turned on to start detection by the photosensors 30 and 32, and at step 520, the signal card data from the photosensors 30 and 32 facing the respective LEDs is output. A
Determines whether the signal and B signal are on/off. If a card is inserted here, at step 12, the l,% deviation of the A signal and B signal or both are turned off by the card, and the display shows r --E.
E--J is displayed to prompt the user to reinsert the card. Then, the signal is constantly monitored by 5tepH, and only when both of them are turned on, it is determined that the card has been removed, and the no card display r-P-J is displayed in 5tep13, and the check is finished.
Proceed to tap14.

If the card is inserted, execute the voltage check routine of the backup power supply 12 of the S-RAM 11.
step 600), proceed to Step 14, 5tap 14
is used to determine the type of inserted card, and if no card is inserted, r-P-J will be displayed on the display section 6 (
Step 14) Once 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 15). The former has data 201 to 203 and is set to unit price setting mode ( S
t e p200), upper limit setting mode (Step300)
), erase mode (Step 400) is executed, and the latter has data from 1 to 200, and department mode (S
Execute the process of teplO,O) (Step 20),
If there is an error when inserting the card, the r
-E E-J display (Step 16).

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. 10 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
At 0, a start pattern is detected, which will be described later. If detected, the data is read in Steps 21-5 and Step 25. To avoid errors, data is only read when the card is inserted within a certain speed range. execute,
Otherwise, the configuration is such that an error message 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 "r 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
Perform r-E-J display by p23.

The system 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
Perform step 24, then increment the data counter by 1 in 5rep25, and continue from step 21 until the counter reaches 8, that is, until 8 bits of card data are completed.
26 data is read.

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, in step 20-1, both the ■ signals of the card data are on, that is, the card has not been inserted yet. Next, in step 20-2, both the ■ and ■ signals are off, that is, the tip of the card. It is recognized in this order that the card has been inserted, and then in Step 20-3, only the 0 signal is turned on, which means that the hole on the signal side of the card has been detected. Here 5tep2
If a detection other than the above is detected in 0-3, 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 either the card data signal or the 0 signal is off, that is, whether it is on the hole side or the 0 side, and at step 24-3, the data on the ■ side is set to 1 on the O20 side. The data is stored in the bits of the C card data corresponding to the contents of the counter.

In other words, in the case of Figure 7, the data is 01010110B, which is 1
In base 0, it is 86.

In FIG. 13, the stop pattern detection is as follows:
5 step 26-1 detects no hole, 26-2 detects a hole only on the side, 26-3 detects no hole once, 26-4 ■,
■Recognize the stop pattern in the order that both detect a hole and 26-5 detects no hole. Here 5tep26
If there is any other detection at -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 10 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 5teplOO-2, pictogram display mark 7-1.7-

- Read from RAM.

In step 100-4, [card data] (department number) and the cumulative number of copies for that department are displayed on the number display section 6. Next, in step 100-5, the copying machine outputs a pulse every time it copies [sheet 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 5tpeZoo-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 prevents copying. 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.

This is necessary to support foreign currencies, and in Japan, up to 0.1 yen is sufficient, but in the United States, for example, up to 0.018 yen is required.

Then, when the ENTER 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, it is displayed on the S-RAMI 1. Write and 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 on the number display section 6 to r-1-.

In the initial stage of the apparatus, when reading all the upper limit data for 200 to 200 sheets, each section is set to the maximum value (100,000 sheets).

Next, 5tep 300-2"t' displays [department data] and [upper limit data] on the number display section 6 when the Φ key 8-1 or the e key 8-2 is pressed.

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. (The 9 key 8-2 should be displayed as -1 in Figure 19 (
