Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image processing apparatus, such as a copying machine or a facsimile apparatus, which reproduces an original image on a recording sheet at the location or a remote location.

[0002]

2. Description of the Related Art Many image processing apparatuses of this type are generally easy to operate so that anyone can use them.
In addition, they are often placed in various places. Therefore, their use is increasing recently. As a result, the number of copies and the number of times of facsimile transmission / reception increase, so that a person who does not need special materials or a person outside the control area can easily send a sentence with a great deal of confidentiality to the outside. However, the risk of information leakage is high.

In order to reduce such a risk, it has been proposed to use a special paper as a manuscript paper or a recording paper (for example, Japanese Patent Publication No. 51-39854). ， There is another disadvantage that even those who have the authority to dispose cannot copy. Further, it is impossible to prevent unnecessary use of the copying machine or the facsimile machine, for example, use by an outsider or a person without copy authority.

In Japanese Patent Laid-Open No. 54-3539, it is possible to make a copy if the input code is a code written in a battery-backed RAM and to count the number of copies corresponding to the code. A method for recording the number of sheets is presented, which uses a microcomputer instead of a conventional mechanical key counter. Japanese Unexamined Patent Publication No. 51-7841 discloses a registration of a personal identification number for a bank's CD. When the user enters a code at the start of use of the CD card, the personal identification number is used as a subsequent personal identification number. Become.

[0005]

However, in both JP-A-54-3539 and JP-A-51-7841, the cancellation of the permission code of the image processing apparatus such as a copying machine is presented. There is no place to do it. For example, in the case of a copying machine, the person who has set the license code for the use or the department who has set the license code for the purpose of revoking the license may cancel the license, or the same license code may continue for a long time. It is necessary to cancel the permit code relatively frequently, such as canceling the previous permit code in order to change the permit code to prevent the leakage of the code. Therefore, management of information documents,
It is preferable that a person having the authority to dispose can cancel the permission code relatively easily.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an image processing apparatus which can be used by inputting a permission code and to relatively easily cancel the permission code.

Codes capable of copying and facsimile transmission, such as 2 ", ..., Are set in the copying apparatus. When the clear key is operated," 01 "or the like input immediately before that is copied or copied. This means that the facsimile transmission has been disabled or set.

Next, the operation of the electronic device 30 based on the code reading program data stored in the fixed memory of the ROM 34 is shown in steps 7 to 15 of FIG. 5, and will be described in detail with reference to FIG. , the power switch 18 is a ON (step 1), a write switch 19 ₄ is OFF (step 2), indicator 25 ₁ is biased on (step 7). Therefore, the operator assigns the code assigned to himself or the section to which he / she belongs, or the code assigned to the manuscript, for example, "01" to the numeric keypad 20.
Input by pressing the "0" display key and the "1" display key.
The electronic device 30 detects this in the scan of the numeric keypad 20 (step 8) and indicates it by the binary code "00000".
"001" is stored in the internal RAM or RAM 35 of the CPU 32 (step 9), the address is specified from the non-volatile RAM 36 to read the memory data, and it is checked whether the read data is "1" (step). 10). In this case, the address of the nonvolatile RAM 36 is “000000”.
If "1" is stored in "01", it is first checked whether the switch 19 ₁ designating the copy mode is ON or OFF (step 11). If it is ON, the copy operation program data is read from the ROM 34. The data is read out and stored in the RAM 35, and the copy operation is controlled according to this program. It is OFF in step 11 and modify the copy mode - switch 19 ₂ to specify de watches ON or OFF (step 12), O

In the facsimile reception recording, when a calling signal arrives from the facsimile reception processing circuit, the power switch 18 is turned on to perform recording operation control according to the facsimile reception recording operation program, and when the calling signal arrives during the operation of the apparatus. , An interrupt that prioritizes received records is performed.

The code "αβ" except that the operator has already addressed "1" to the nonvolatile RAM 36 and memorized "1", where α and β are any numbers from 0 to 9,
Is input by the numeric keypad 20, the read data of the RAM 36 is "0" which designates the disable of the copying operation or the facsimile operation in step 10, so that the power switch 18 is turned off (step 15). In this case, instead of turning off the power switch 18, the buzzer 27 may be energized, and other alarm lamps are turned on or a memory for the operator input code to the RAM 35 or 36, Recording of operator input code to the magnetic recording device, etc.
May be performed. When the operator does not input a code, the copying machine is in a standby state with the power turned on, and the apparatus does not operate even if the print switch 21 is turned on.

In the embodiment described above, the data,
As described above, the administrator of the document or the like inputs the operable code into the copying apparatus under its jurisdiction in advance so that the operation of the apparatus is not performed except the input of the code. In addition, when the operable code has already been input, the operable code is input and immediately after that, the clear key is operated to change the code to the inoperable code. It is the one. Therefore, the usage of this embodiment is as follows, for example.

(1) A, B, C, D, ... X only "01", "02", "03", ...
Only one code such as the above is notified, and the code is input to the copying apparatus (writing of data to the RAM 36). In this case, the persons other than A to X cannot use the copying machine because they do not know the operable code.

(2) A code is attached to a management material or document, and the code attached to the material or document is input, and then a copy or a facsimile transmission is performed. Codes that enable operation when needed are encrypted and / or coded.
Change the code or code regularly or irregularly. The cord that is no longer needed can be read with the switch 19 ₄ closed.
It is erased by inputting at 20, and then turning on the clear key.

The program data for writing to the nonvolatile RAM 36 is the write switch 1 in step 2.
When 9 ₄ is detected to be ON, “1” is stored in the RAM 36.
A step but displaying an address that is not the memory on the display panel 24 ₁ or 24 _2, key - one of the switches, for example, "1" display key weather -20 - When pressed, the "1" to the address It may be replaced with a step including a writing step.

The non-volatile RAM 36 may store data represented by an input code. FIG. 6 shows a flow of writing into the RAM 36 and a code judging flow in such a case. In this, 15 steps show 1-15 respectively the same or equivalent steps as shown in FIG. 6, in which, the write switch 19 ₄ and is ON (step 2), first indicator 25 ₂ is urged turned on (step 16), which is the memory address U RAM36 worker - one which facilitates the input of the de. When the operator scans the numeric keypad 20 (step 17), the input code is the internal RA of the CPU 32.
It is stored in M or RAM 35 (step 18), and then the indicator lamp 25 ₁ is energized (step 3). When the operator presses the two keys on the numeric keypad 20, the code previously stored is used as an address and the code input later is written in the RAM 36 (step 6). The memory data code is input next to the input of the previous memory address code.
When the clear key is operated instead of inputting the code, the memory code of the address designated by the memory address code is cleared (A1, A2).

In the code judgment flow shown in FIG. 7,
It is determined whether or not the input code exists in the memory data of the RAM 36 (step 19), and only when it exists, the device operation control from step 11 onward is performed. In this way co - the de own Memoride - even if the data, a write switch 19 ₄ is ON (step 2), co -
De de - data is displayed an address of RAM36 which is not the memory on one of the display panel 24 _1, posted in this state -
It may be a program for writing data - performing two-digit number input by 20 if and displays it on the other display panel 24 _2, de displayed on the 24 ₂ to the address displayed in 24 _1.

In order to further ensure confidentiality, a copyable code or a non-copyable code may be added to the document itself in place of or in addition to the code input by the operator to the image processing apparatus. It is preferable to add a mark and read it with a reader for comparison with the memory data.

FIG. 8 shows an example of the structure of an optical reader for reading the code on the original using the image signal of the image reading element 16. In this example, the optical reader 50 includes a shift register SH, first and second counters, COU2, AND gates AN1 to AN16 and flip-flops F1 to F1.
It is composed of fifteen. In the shift register SH, an image signal of a predetermined level Vref or higher is output by the comparator 40 as "1":
A binary image signal in which black is used and an image signal below a predetermined level is set to “0”: white is provided, and 1728 (8 / mm scanning density) scanning is performed on the original image for each short side length of A4 plate. A main scanning synchronizing pulse used for reading the CCD element 16 emitted at a rate is applied. The shift register SH is 1
Since it has a 6-bit serial shift stage and the output of each stage is applied to the AND gate AN1, when the serial 16 dots of the image signal are all black: "1" The output becomes "1" and is applied to the AND gates AN9 to AN15. Counter COU1
Is cleared by the sub-scanning synchronization pulse generated at a rate of 1 pulse for each scanning of one line of the short side of the document, and counts the main scanning synchronization pulse. Therefore, the count code of the counter COU1 indicates where the current reading scanning position (short side direction: main scanning direction X direction) of the original image is. The counter COU2 is cleared by the print start signal and counts the sub-scanning synchronization pulse. Therefore, the count code of the counter COU2 indicates where the current reading scanning position (long-side direction: sub-scanning Y direction) of the original image is. The AND gates AN2 to AN8 produce an output of "1" at the code position in the main scanning direction X on the document, and the AND gate AN16 outputs "1" at the code position in the sub scanning direction Y on the document. Are connected to counters COU1 and COU2, respectively.

In this example, as shown in FIG. 9, when one corner of the manuscript IP is aligned with the reference point (reading scanning start point) 00 of the reference frame SS of the manuscript placing table, seven pieces are arranged. Ma - click M ₀ ~M ₆ (corresponding to binary 7-digit 2 ^{0-2 6} respectively) to read, Andoge - Doo AN2~AN8 counter COU1, also Andoge - DOO AN16 is connected to a counter COU2 Has been done. This will be explained a little more concretely. As shown in FIG. 10, it is assumed that the shaded area is colored black for the code, and y ₁ from the reference point 00
Is 4 mm, y ₂ is 8 mm, X _{1 to} X ₁₆ are Xi
= 8 × imm, i = 1 to 16, and AND gates AN2 to AN8 are respectively X ₁ , X ₃ , X ₅ , ... X ₁₅
When there is a main scan, the output of "1" is generated, and
The output of the AND gate AN16 produces a "1" when the sub-scan is at y ₁ and the outputs of the AND gates AN2 to AN8 and the outputs of AN16 respectively flip-flops F1 to F1.
7 and F15 are set. Flip-flop F1
~F7 the main scanning X _2, X _4, is connected to the counter COU1 be reset when in the · · · X _16, as the flip-flop F15 is reset when the sub scanning is in y ₂ Is connected to the counter COU2.
The Q output of the flip-flop F15 is the AND gate AN9.
~ Applied to all of AN15, flip-flop F1
Q output of ~ F7 is AND gate AN9 ~ AN1 respectively
5 is applied to each. Therefore And Gate AN9
Is the code area 2 ⁰ (X ₁ ,
X ₂ , y ₁ , y ₂ ), it is turned on and becomes black for 2 mm (16 bits) in the main scanning direction,
That is, when the code index is present, an output of "1" is generated and the flip-flop F8 is set. Similarly, the image reading scan is co - when in the respective de region 2 ¹ to 2 ^7, when has a black over 2mm in the main scanning direction, Andoge - outputs DOO AN10~AN15 is "1" And flip-flops F9 to F14 are set. In this way, the co - de index, defined regions 2 ⁰
.About.2 ⁷ ("1") or not ("0") is set in the flip-flops F8 to F14. Incidentally, Q output of the F15, the copy of the index of light is emitted OFT3 at corresponding positions y ₁ ~y ₂ on the drum taking a rotational and synchronization of the drum 1 index regions 2 ^{0-2 6} - as a signal for preventing In the facsimile transmission mode, it is given to the input / output port 31 as a signal for preventing the image reading. When the sub-scanning reading reaches y ₂ , the code reading command is input / output port 31.
Given to.

When such an optical reader 50 is used, the print switch 21 is turned on and the carriage starts to move forward (Y direction) as shown in an example of the operation flow in FIGS. 11 and 12. The code of the manuscript IP is read from it to determine whether or not it is stored in the RAM 36. If it is stored in the RAM 36, the image processing operation is continued as it is. If not, the power switch 1
The program data for turning OFF 8 may be stored in the ROM 34. When the read code is stored in the RAM 36, the power switch 18 is turned off.
It may be set to F.

In this embodiment, the operation of inputting the code with the numeric keypad 20 is unnecessary when performing copying or facsimile transmission. A magnetic reader based on magnetic sensing may be used as the reader, and a code may be attached to the original with a magnetic film. When doing so, for example, as shown in FIG. 13, an inductor core 6 around which an induction coil is wound.
The magnetic substance detection head 60 in which 1 and the detector core 62 wound with the detection coil are integrated may be arranged at a position for detecting the magnetic film code index of the original as shown in FIG. 14, for example. In this way, the back surface to the magnetic Makuko - co the original IP painted a de indicator while matching the positioning frames SS put on the contact glass plate as shown in Figure 15 - the detection head de 60 _through 603 Detectable with ₅ . It is possible to detect the code before driving the optical scanning carriage forward. For optical detection, the heads 60 _{1 to} 60 ₅ may be reflective photosensors.
