[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD This invention relates to a management device for managing equipment usage information such as managing the number of copies in a copying machine. Prior Art For example, in a copying machine management device disclosed in Japanese Patent Application Laid-Open No. 57-27846, copies can be made by inserting a department card recorded with an arbitrary department number, and the number of copies is determined by the department. The information is managed and stored in the memory within the management device according to the number. In the management device of this type of copying machine, if a department card is lost, the department number of the lost card can be registered in the internal memory of the management device as a way to prevent the lost card from being reused. , methods have been proposed to prohibit the copying operation or issue a warning when the device is inserted into the device. However, this method has the disadvantage that if a lost card is inserted into another similar type of management device, it will become possible to copy unless the department number of the lost card is registered in the invalid memory. . Purpose of the Invention The present invention has been made to eliminate the above-mentioned drawbacks, and involves storing or setting a different verification code in each management device, and comparing the card with the stored verification code. It is an object of the present invention to provide a management device that can prevent a lost card from being misused by allowing the card to be used only when the two cards match. When a verification code is set in the management device as described above, it is also necessary to write the verification code on the card, and this writing operation becomes complicated. Therefore, another object of the present invention is to provide a management device that allows easy writing of a verification code onto a card. Structure of the Invention In order to achieve the above-mentioned object, the management device of the present invention is a device management device that manages the operation of the device by installing a predetermined storage medium, and includes a storage means for storing a verification code; a collation means for collating a collation code stored in the storage means with a collation code stored in an attached storage medium, and the collation means prohibits operation of the device when both collation codes do not match. a verification code detection means for detecting whether a verification code is stored in the attached storage medium; and a verification code detection means for detecting whether or not a verification code is stored in the installed storage medium; and means for writing the verification code into the attached storage medium. In the management device of the present invention having the above configuration, for example, a different verification code is set or stored for each copying machine, and when a card is set in the management device, the verification code in the management device and the verification code in the card are first checked. If there is a mismatch, copying is not permitted. Therefore, even if a card is lost and then rediscovered, it will be printed on a different copying machine.
Due to a mismatch in the verification code, the copier cannot be used. This prevents card abuse. Furthermore, when the verification code detection means determines that no verification code is written on the card set in the management device, the verification card set or stored in the management device is written to the card. written by means. Therefore, there is no need for the copying machine manufacturer to write the verification code on each card, and when the copying machine user sets the card in the management device, the verification code is automatically written on the card. Embodiment FIG. 1 shows an external view of an example of an electrophotographic copying machine to which the present invention is applied. A copy machine management device 101 that manages the copy machine body 100 using a magnetic card is electrically connected and installed on the copy machine body 100, and the copy machine management device 101 is also arranged on the operation section 102 of the copy machine body 100. It is also associated with operation keys 103 including a numeric keypad. Next, FIG. 2 shows a schematic configuration of an example of an electrophotographic copying machine 100 to which the present invention is applied, and first, an outline of the configuration and operation of the copying machine will be explained with reference to this diagram. A photoreceptor drum 10 is located approximately in the center of the copying machine body.
is supported rotatably in the direction of the arrow in the figure, and around it, an erase lamp 11, a charging charger 12, a developing device 13, a transfer charger 14, a cleaning device 15, etc. are arranged in this order. An original (not shown) is placed on the original placing glass 21, and is scanned by an optical system 20 including a lamp 22, reflecting mirrors m1 to m4, and a lens 23, and its image is sequentially placed on the photosensitive drum 10. projected on. The configuration of the optical system and the scanning operation itself are well known, and therefore will not be specifically explained. The paper feeding device 30 consists of a paper feeding roller 31' and a holding mechanism 32 that holds the laminated sheet S, and rotates the paper feeding roller 31' in synchronization with the copying operation.
As a result, the stacked sheets S are sent out one by one starting from the top one, and are transported toward the photosensitive drum 10 via the transport rollers 33, 34, the timing roller 35, and the like. In the above configuration, the photoreceptor drum 10 rotates with the start of the copying operation, and an image is formed on the surface of the photoreceptor drum 10 by charging, exposure, and development, and this image is synchronized with the image forming operation. The image is transferred onto the conveyed copy sheet by the transfer charger 14.
The copy sheet after the transfer is separated from the surface of the photoreceptor drum 10, passes through a fixing device 16 to have the image fixed thereon, and is then discharged onto a tray 17. After the photosensitive drum 10 is transferred, residual toner and residual charges are removed by a cleaning device 15 and an erase lamp 11, and the photosensitive drum 10 is prepared for the next copying. Note that M1 is a main motor that drives the photosensitive drum 10, optical system 20, copy sheet conveyance system, etc., M2 is a developing motor, CL1 and CL2 are clutches for scanning and returning the optical system 20, and CL3 is a clutch for scanning and returning the optical system 20. Timing roller clutch and CL4
is the paper feed roller clutch. The configuration and operation of the copying machine management device 101 will be explained step by step. FIG. 3 is an external view of the present copying machine management device 101, which includes a card insertion section 301, a display section 302, operation keys SW1 and SW2, a magnetic card reader and writer section 601 to be described later, a control CPU 600, and the like. Figures 4 and 5 schematically show the internal structure. In order from the card insertion section 301 to the right, a data recording timing detection pulse disk 43, a pulse detection sensor 44, a card transport upper roller 42,
A read and write magnetic head 41, a card transport guide 401, a card transport motor 45, and a card end detection switch SW4 are provided. Also, from the left side when facing the front of the copying machine management device 101, a card tip detection actuator 52,
A card leading edge detection switch SW3 and a card transport lower roller 51 are arranged in this order. Next, a series of operations from card insertion to card ejection will be explained with reference to the drawings. First, the card insertion section 30 of the copying machine management device 101
1 (magnetic card 31 differentiated for department, individual, tally, erasure, service personnel, etc.) is inserted, and when the card tip detection switch SW3 is turned on, the transport motor 45 rotates forward (counterclockwise in the direction of Figure 4). ), the card 31 is sandwiched between the transport upper roller 42 and the lower roller 51, and the transport guide 40
1 and transported inside. Here, data on the card 31 is taken into the control CPU 600 through the magnetic head 41 while the card is being transported. When the tip of the card 31 turns on the card end detection switch SW4,
The transport motor 45 is stopped and the data previously taken into the control CPU 600 is processed. For example, this processing enables the copying operation of the copying machine 100, stores the number of copies by department or size, stores paper jam or trouble information by location or time, or stores the above-mentioned stored information. This is processing such as displaying on the display unit 602. Next, when the operation key SW2 is turned on, the display section 302
After processing such as turning off the above display or prohibiting the copying operation of the copier 100, the transport motor 45 is reversed, and if there is no need to record data on the card, the card is ejected as it is to the insertion section 301 and a series of operations are performed. finish. When it is necessary to record data on the card 31, the output of the data recording timing detection pulse disk 43, which rotates in conjunction with the rotation of the motor 45, is input to the control CPU 600 via the sensor 44, and the card 31 is ejected. Data is recorded on the card 31 through the magnetic head 41 in conjunction with the operation. When data recording is completed, the transport motor 45
After stopping, the motor is rotated forward to confirm the recorded data, and the data on the card 31 is again taken into the control CPU 600 through the magnetic head 41. The tip of the card 31 is the card edge detection switch SW.
When 4 is turned ON, the data recorded on the card 31 first and the data read after recording are controlled by the CPU 60.
0, and if the former and latter data match, it is determined that the data has been recorded correctly, the transport motor 45 is reversed, the card 31 is ejected to the insertion section 301, and the series of operations ends. do. If they do not match, it is determined that a recording error has occurred, and the recording and reading processes are repeated as described above. The format of the data recorded on the magnetic card is
It may be a standard unified by JISB9561, or it may be a unique data format. FIGS. 6 and 7 show circuit diagrams of the present copying machine management device 101. The CPU 600 has a magnetic card read/write section 6.

are connected to input/output ports 74 to 78 shown in FIG. External RAM 606 and clock 607
is backed up by a battery 608 so that the recorded contents will not be erased when the power is cut off. The magnetic card read/write section 601 includes a read head 71, a waveform demodulation and shaping section 79, an input gate 81, a write head 72, a waveform modulation section 80, and the like. In this embodiment, the magnetic head 41 has a reading 71 and a writing 72 separate from each other.
A single gap head common to read and write may also be used. Further, the CPU 600 of the copying machine management device 101 is
It is connected to the CPU 609 of the copying machine main body 100 by a communication signal line 610, and data is transmitted and received through this signal line. CPU600 used for sending and receiving this data
As shown in Table 1, the terminals are serial out terminal So for serial data transfer, serial in terminal Si for reception, and data sampling clock terminal.
sck and interrupt terminals. As a specific data transfer method, the one proposed in Japanese Patent Application Laid-Open No. 59-127133, etc., or any other arbitrary method may be used. Tables 2 and 3 show examples of data transferred from the CPU 609 of the copier main body 100 to the CPU 600 of the copier management device 101, and Table 4 shows examples of data transferred from the CPU 600 to the CPU 609.
Table 5 shows the results. Here, it is assumed that each information content of the transfer data is coded, for example, as shown in Table 3 (1) to (4) below. The status signals are as shown in Table 6, for example. Next, the control operation of the copying machine will be explained. In step S1 shown in Fig. 8, each flag (including the copy flag) is reset, the set number of sheets, paper feed slot,
Initializes data such as paper size and copy magnification. Next, in step S2, a main timer for defining the length of one routine is set. In step S3, input processing from various keys and switches including the operation key 103 of the operation unit 102 and output processing to the motor, solenoid and display device are performed. In step S4, it is determined whether or not the copy status signal transmitted from the control CPU 600 of the copying machine management device 101 through the above-mentioned communication is 0 (that is, if the copy status signal is 0, the copy operation is possible; if it is 1, it is determined whether the copy status signal is 0 or not). If copying is prohibited, the process advances to step S11. If copying is possible, it is checked in step S5 whether the copy flag F is 1 (that is, if it is 0, the copying machine main body 100 is on standby;
If it is 1, it is in the process of copying), and if it is 1, it goes to step S8, and if it is 0, it goes to step S8.
In S6, it is determined whether or not the print key of the operation keys 103 has been pressed. If NO, the process proceeds to step S11; if YES, the copy flag F is set to 1 in step S7, and the process proceeds to step S8. Step S8 performs various copying processes, and
It is determined in S9 whether or not copying has been completed. If YES, the copy flag F is reset in step S10 and the process proceeds to step S11; if NO, the process directly proceeds to step S11. In step S11, the various data transmission and reception processes described above are performed. Then, in step S12, it is determined whether the main timer set in step S2 has ended, and YES
If YES, return to step S2, and if NO, repeat step S12 to adjust the length of one routine. Next, the operation of the copying machine management apparatus 101 will be explained based on the flowcharts shown in FIGS. 9 to 14. When the power of the copying machine 100 is turned on in FIG. 9a, initial settings of the management device 101 are first performed in step S20. Next, in step S21, the card edge detection switch SW3 determines whether or not the magnetic card 31 is inserted into the card insertion section 301. If the magnetic card 31 is already inserted when the power is turned on, the motor is activated in step S23. 45 is reversed, and if the magnetic card is not inserted or removed, the motor 45 is stopped in step S22. Next, in step S24, "CARD" is displayed on the display section 302, and the step
In S25, it is determined whether the card end detection switch SW3 is turned on or not, that is, whether the card is inserted or not.
If the card has been inserted, the process advances to step S26, and if the card has not been inserted, step S25 is repeated. In step S26, the motor 45 is rotated in the normal direction, and the card 31 is transported inside along the transport guide 401. In step S27, the data on the transported card is taken into the control CPU 600 through the magnetic head 41. In step S28, it is determined whether the card end detection switch SW4 has been turned on, that is, whether the card 31 has been completely inserted into the card, and if it has been inserted, the process proceeds to step S29.
The motor 45 is stopped at step S27, and if feeding is in progress, the process of step S27 is repeated. In step S30, it is determined whether or not the card ejection switch SW2 has been pressed. If it has been pressed, in step S31, the copy status signal (Table 5 (2)) to be transferred to the copying machine 100 is set to a copy disabled state, and then Then, in step S32, the motor 45 is reversed. In step S33, it is determined whether the write flag is 1 or not. The write flag is a flag that is set to '1' when data needs to be written on the card, and is reset to '0' otherwise. If the write flag is '0', the process advances to step S21 and card ejection processing is performed. If the write flag is '1', data is written in step S34. In the write process, write data is sent through the modulator 80 to the write head 72 of the magnetic head 41 in synchronization with a write timing pulse input to the CPU 600 by a pulse disk 43 that rotates in synchronization with the conveyance of the card and a detection sensor 44. Processing that is performed by turning on and off electric current. In step S35, it is determined whether the write process has been completed, that is, whether all data has been written. If YES, the process advances to step S36; if NO, steps S34 and S35 are repeated. When the writing is completed, the motor is rotated in the forward direction in step S36, the data previously written on the card in step S34 is read again in step S37, and the data is returned to the card in step S37.
In S38, it is determined whether SW4 is turned on or not, and if NO, steps S37 and S38 are repeated. If YES, stop the motor at step S39 and proceed to step S39.
Proceed to S40. In step S40, it is determined whether the data written in step S34 and the data read in step S37 are equal, and if they are not equal, the process proceeds to step S32.
Return to and perform the write process again. If they are equal, the process returns to step S21 to perform card ejection processing and end the series of operations. If the card ejection switch SW2 is not pressed in step S30, the process advances to step S41 in FIG. 9b. In step S41, it is determined whether the read card is a department card or not. If YES, processing is performed in step S42 and the process returns to step S30. If NO, it is determined in step S43 whether or not it is a personal card; if YES, processing is performed in step S44 and the process returns to step S30. If NO, proceed to step S45. Similar processing is performed in steps S45 to S50 for aggregation, deletion, and serviceman cards. If it is determined in step S49 that the card is not a serviceman's card, it is determined that the card has a reading failure or is of a different type, and "ERROR" is displayed on the display section 302 in step S51, and the process returns to step S21 to perform card ejection processing. Figures 10 to 14 are the steps in Figure 9b.
This is a flowchart showing details of the processing of S42, S44, S46, S48, and S50. In FIG. 10a, it is first determined in step S101 whether or not the mode is the department number setting mode. If YES, proceed to step S102; if NO, proceed to step S102.
Proceed to S105. The department number setting mode is a mode for recording an arbitrary department number on the department card, and this judgment is made if the department number is a specific number (such as "00") in the data read from the card. This is done in some cases and depending on whether a dedicated flag is set. An example of the data format on the card is shown in FIG. In step S102, whether the department number is input or not, that is, whether the department number is
3 to determine whether the department number has been input,
If it has been input, the input department number is set in the write data area in step S103, the write flag is set to 1 in step S104, and the process returns to step S30. If the department number has not been input, the process directly returns to step S30. This operation allows the department code to be input using the keys. If it is determined in step S101 that the mode is not the department number setting mode, that is, if the department number has already been recorded, it is determined in step S105 whether or not the mode is the collation number setting mode. The verification number is a number for determining whether or not a card can be used with a specific management device 101, and is a number that is used to determine whether a card can be used with a specific management device 101.
The collation number stored in the memory 606 backed up by the 01 battery 608.
Only cards that match can be used. The verification number setting mode is a mode for recording the verification number on the card, similar to the department number setting mode. In the case of verification number setting mode, the verification number stored in the memory is transferred to the write data area in step S106, and the write flag is set to 1 in step S104.
and return to step S30. If you are not in the verification number setting mode, that is, if the verification number has already been recorded on the card, the step
Compare the verification numbers on the card and memory in S107,
If they do not match, "NOGOOD" is displayed on the display section 302 in step S114 to indicate to the operator that the card cannot be used, and the process proceeds to step S21.
Return to and perform card ejection processing. If they match, copying is enabled in step S108, and in step S109 it is determined whether the operation key SW1 is on, and if it is on, the department number, paper size, and department are displayed on the display 302. Displays the total number of copies for each paper size, and if operation key SW1 is off, step S111
The department number and the total number of copies for each department are displayed, and the process proceeds to step S112. In step S112, it is determined whether the copying machine 100 has started copying and fed paper, and if paper has been fed, the department is notified in step S113.
The content of the corresponding tally area is updated according to No. paper size, and the process returns to step S30. If no paper has been fed, the process directly returns to step S30. In FIG. 10b, it is determined in step S120 whether the mode is the balance setting mode. Unlike department cards, personal cards cannot be copied forever; they are cards that cannot be copied once a certain amount or number of cards is reached, and the upper limit is set by the balance. . The determination as to whether or not the mode is the balance setting mode is made in the same way as the department number setting mode.If the mode is the balance setting mode, the operation key 10 of the copying machine 100 is pressed in step S121.
3, it is determined whether the balance has been set, and if there is an input, the balance is set in the write data area in step S122, the write flag is set to 1 in step S123, and the process returns to step S30.
If there is no input, the process directly returns to step S30. If it is determined in step S120 that the card is not in the balance setting mode, that is, if the balance has already been recorded on the card, it is determined in step S124 whether or not it is in the verification number setting mode in the same way as for the department card.
If YES, the verification number is transferred to the write data area, the write flag is set to 1 in step S123, and the process returns to step S30. If NO, the verification numbers on the card and in the memory are compared in step S126, and if they do not match, "NOGOOD" is displayed on the display section 302 in step S135, and the process returns to step S21. If they match, the balance read from the card is displayed in step S127, and the balance read from the card is displayed in step S128.
Then, it is determined whether or not the remaining amount is greater than 0. If the remaining amount is 0, copying is prohibited in step S134 and the process returns to step S30. If the balance is greater than 0, step S129
to permit copying, and in step S130 it is determined whether or not paper has been fed. If paper has not been fed, the process returns directly to step S30; if paper has been fed, the balance is updated in step S131, the updated balance is transferred to the writing area in step S132, and the process continues in step S133.
The write flag is set to 1 and the process returns to step S30. If it is a tally card in step S46 of FIG. 11, data such as the number of copies by department and the number of copies by size, which are managed and tallied in the memory, are displayed on the display section 302 in step S150, and the process returns to step S30. If the erased card is determined in step S48 of FIG.
Display “ALL CLEAR” in S161 and proceed to step S162
The various data managed on the memory are erased and the process returns to step S21. If operation key SW1 is not turned on, "CLEAR" is displayed in step S163, and step S30 is displayed.
Return to In the case of a serviceman card in step S50 of FIG. 13, in step S170 various information regarding paper jams and troubles in the copying machine main body 1 managed in the memory is displayed on the display section, and the process returns to step S30. FIG. 14 shows the processing when an interrupt is generated from the copying machine CPU 609. When an interrupt occurs, the information to be transmitted is set in a serial transfer register (not shown) in step S180, and serial data is transmitted and received simultaneously in step S181 in synchronization with the clock transmitted from the CPU 609. When the transmission and reception are completed, step
In S182, the information sent from the copying machine is stored in memory, and if the data received in Step S183 includes JAM/trouble information, the contents of the corresponding memory area are updated in Step S184. Ends interrupt processing. If no JAM/trouble has occurred, interrupt processing is immediately terminated. Although the above-mentioned embodiment has been described with respect to a copying machine management device, the present invention can be applied to other optional devices.
