Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention enables a device to be put into a movable state by loading a portable data medium that is removable from the main body of the device, and that allows copying and copying by this portable data medium. The present invention relates to a copying apparatus that manages the number of sheets.

[Technical background of the invention]

'-As a conventional portable data medium of this kind, for example, there is one as shown in FIG. 10 or FIG. 11. The one shown in FIG. 10 is so-called. By inserting this key counter into a key counter socket (not shown) provided on the main body of the copying machine, the pin P at the rear of the key counter is connected to the glue receptacle in the socket. The key counter and the copying machine are electrically connected.

In this case, the copying machine becomes ready for copying only when the key counter is loaded, and from then on, the key counter sequentially counts the number of copies made in response to the copying operation, and the counting result is displayed on the front panel. It is displayed on the display section.

The one shown in FIG. 11 uses a so-called magnetic card M, and a high magnetic card Mζ has a predetermined password magnetically stored in advance. Then, if this magnetic card M is inserted into the magnetic card reader box installed on the side of the copying machine, after the PIN code stored in the magnetic card M is checked, the copying machine becomes ready for copying. It looks like this.

[Problems with background technology]

However, when using a key counter, (1) the copier becomes ready for copying simply by connecting the pins of the key counter to the key counter socket glue receptacle terminal on the copier main body, which requires some electrical knowledge. C) The display section showing the total number of copies is easy to modify, and other problems exist.

In addition, those using magnetic cards: (1) Since a magnetic stripe is used as a recording medium, the stored contents are easily destroyed by external magnetism such as an electric appliance.

(2) Since the stored contents are easy to read, they are easily exploited by plagiarism, forgery, etc.

O) In order to install other useful functions, the storage capacity is 0.5
There are problems such as the size is too small, 1.2 bits to 1.2 bits.

[Purpose of the invention]

By seeing this lighting display, the customer inserts the IC card 1 into the card insertion slot 81 of the IC card reader/writer. Then, the IC card 1 is conveyed on the conveyance path 82 by the conveyance roller 83 and taken into the IC card league writer 80 (steps A31 and A32). Then, when the IC card 1 faces the static elimination brush 85,
When the brush comes into contact with the terminal 6 of the ICC case, the accumulated static electricity (electrostatic charge) is discharged through the static elimination brush 85 and thereby removed. Thereafter, the IC card 1 is conveyed along the conveyance path 82 and faces the reader/writer 86 .

For example, in such a state, the microcomputer 91 lights up the display lamp 74 to provide guidance "Please key in your password" (step A66).

In response to this guidance, the user inputs the password using the numeric keypad 56. Upon this input, a signal corresponding to the password is supplied from the microcomputer 91 to the CPU 4 via the reader/writer 86 and the connector 3. Thereby, the CPU 4 temporarily stores the supplied user's password in the iRAM 9. Next, the CPU 4 reads the pre-written password from the data memory 5 and compares it with the password stored in the RAM 9 (step A64°As2). If the comparison result is a match (step A66), the CPU 4 outputs a match signal to the microcomputer 91. Then the microcomputer 91
erases the display of the password key-in 74 and displays a ready display 62 indicating a copy-capable state, and enters a copy-capable state (ready state).

Further, if the above comparison results do not match, the CPU 4 outputs a mismatch signal to the microcomputer 91. Then the microcomputer 91
In step A37), the indicator lamp 75 indicating the mismatch of the PIN number is turned on, and the PIN key-in lamp 74 is turned on again to guide the user to key in the PIN number.

In step B20, it is determined whether or not the 30 second reset timer has counted up. If it has not counted up, the process returns to step B1, and if it has counted up, the process advances to step B21. In step B21,
Initialization such as canceling the bypass paper feeding mode, setting the cassette paper feeding mode, setting the set copy number to "1", and setting the copy magnification to the same size is performed at the same time), and the process returns to step B1. In this way, after selecting bypass paper feeding mode, if no key operations are performed for a certain period of time (30 seconds), the mode will switch to cassette paper feeding mode, and if any key operation is performed, the mode will switch to cassette paper feeding mode for a certain period of time (30 seconds). After 30 seconds have elapsed, the mode is switched to the cassette paper feeding mode.0 However, when the copy key 51 is turned on in step B1, the copying operation is started. That is, when the copy key 51 is turned on, the process advances to step B22. In step B22, the platen renoids are turned on and the process proceeds to step B23.

In step 883, the exposure lamp 64 is turned off and the process proceeds to step B84. In step B84, it is determined whether it is a single copy or the last sheet of continuous copying, and if not, step B29. Return to B50 (see FIG. 9C) and repeat the same operation as described above, and if so, proceed to step B8.
Proceed to step 6. In step B86, it is determined whether or not the paper has been ejected. If the paper has been ejected, the process returns to step B7 (see Fig. 9). In this case, since the platen lenoid is in the on state, step B87 (see Fig. 9) is performed. (See).

In step B87, the developer solenoid of the selected developer is turned off, and the process proceeds to step 888. Step 888
Then, the process proceeds to step B89 with a delay of, for example, 1.0 seconds. In step B89, the main motor 40, developer drive motor, static elimination lamp 29, transfer charger 26, and stripping charger 27 are turned off, and the process proceeds to step B90. In step B90, for example, with a delay of 0.7 seconds, step B9
Go to 1. In step B91, the blade solenoid is turned off and the process returns to step B17 (see FIG. 9).
Repeat the same operation as above. As a result, if copying is performed in the bypass paper feeding mode, the mode is automatically switched to the cassette paper feeding mode after a certain period of time has passed after the copying is completed.

The above operations are repeated to perform the copying operation. In addition, during this repeated operation, the data indicating the total number of copies and the number of copies of each color in the RAM 9 of the IC card 1 is updated every time one copy is completed according to the signals sent from the microcomputer 91. has been updated by +1.

Thereafter, when the copying operation for the required number of sheets is completed, the user presses the copy end key 76 on the operation panel 50. When detecting the input of the key 76, the microcomputer 91 sends a signal indicating the end of the copy operation to the CPU 4 of the IC card 1 via the IC card reader/writer 86. Having received the signal, the CPU 4 uses the RAM 9 to R the data indicating the updated total number of copies and the data indicating the number of copies for each color.
It is read from AM9 and sent back to FROM5 for storage. When the write operation to the FROM 5 is completed, the CPU 4 notifies the microcomputer 91 of this fact via the IC card reader/writer 86.

The microcomputer 91 controls the drive system 98 to
The conveying roller 83 in the C card reader/writer 80 is rotated in the opposite direction to that when inserting the IC card.

As a result, the IC card 1 is transported toward the card insertion slot 81 and stopped at a position where the user can take it out. The user may take out the IC card 1 and then store it appropriately.

In this embodiment, the apparatus includes a mechanism for loading the IC card 1 into the apparatus, and a mechanism for transmitting and receiving data between the CPU 4 in the IC card 1 and the microcomputer 91 in the apparatus. A device is provided to carry out the process, and the IC card 1 with a predetermined password code set in the built-in data memory 5 is loaded into the device by the above-mentioned mechanism.
Compare the PIN code read from the data memory 5 in the IC card 1 based on data exchange between the CPU 4 and the microcomputer z91 with the PIN code input by the user via the numeric keypad 56 of the copying machine body 10; The copier body is set to the ready state only when both codes match. The data memory 5 is the CPU in the IC card 1.
The IC card 1 can only be accessed by using the IC card 1, and the copying machine will not become ready unless the user enters the same code as the preset password in the data memory 5. Only users who know the password data can use the copying machine, and misuse of the copying machine can be reliably prevented.

Furthermore, since data such as the total number of copies is stored in the data memory 5 of the IC card 1 in a constantly updated state, for example, when a copying machine is rented,
When a salesperson checks the number of copies per month, by reading the stored contents of the data memory 5 of the IC card 1 using an appropriate reading device, the salesperson can avoid the total counter on the operation panel, which is easily tampered with, as in the past. Unlike checking the count value of 57, you can easily know the exact total number of copies.

The above embodiment can be modified as appropriate without departing from the spirit of the present invention; for example, the IC card reader/writer for loading the IC card 1 into the main body of the copying machine is not limited to the above embodiment, but may be modified as appropriate. It would be better to adopt a mechanism.

Further, in the above embodiment, the CPU 4 in the IC card 1 performs the password verification process, but the process may also be performed by the microcomputer 91 on the copying machine main body side.

Further, in the above embodiment, the copying machine is set to the ready state when the password codes match, but the present invention is not limited to this. For example, when the difference between the stored code and the input code reaches a predetermined value, the copying machine is set to the ready state. In other words, the device may be controlled to be in the ready state when a predetermined relationship is established between the two codes.

Furthermore, in the above embodiment, the user enters the PIN code set on the device side through the operation unit, but the PIN code may also be stored in an appropriate memory in the device in advance. .

By the way, the IC card used in the present invention has a built-in CPU and a radar memory with a large storage capacity, and if these are used effectively, the copier can perform a variety of functions not limited to counting the number of copies. It is possible to have it.

〔Effect of the invention〕

As explained above, according to the present invention, an IC card having a built-in CPU chip and a data memory that is read/write controlled by the CPU chip is used, and the password data pre-stored in the data memory of the IC chip and the operation section Since the device is placed in a ready state based on verification processing with the password data entered by the user via It becomes like this.
