Indicate whether the user in the department is allowed to copy.

  In addition, a plurality of counters corresponding to the print color, the paper size, or a combination thereof are prepared as counters related to printing by the copy function.

  The counter whose counter type is [Print.Total] relates to the number of printed sheets by the PC print function or the transmission data print function. That is, this counter counts down the number of prints from the current value as the image forming apparatus 1 performs printing based on one of both functions, and how many sheets are printed by both functions. Re-explain whether to allow users in the department.

  In addition, as with the [Copy. To] counters described above, a plurality of counters corresponding to the print color, paper size, or combination thereof are prepared as counters related to printing by the PC print function or the transmission data print function. ing.

  Counters with a counter type of [ScanFax.Print] can be used for printing with image data that has been backed up (saved or stored) in a box among image data sent to other devices using the fax transmission function or scan transmission function. This relates to the number of prints (for example, prints associated with receiving a fax) using image data transmitted from the apparatus. In other words, this counter counts from the value that the number of prints currently has in accordance with the image forming apparatus 1 performing printing using image data backed up in a box or image data transmitted from another apparatus.

That is, as the image forming apparatus 1 performs color printing, this counter counts down the number of color prints from the value that it currently has, and shows again how many color prints are allowed for users in that department. . Which function is used for color printing and the size of the paper do not matter.

  The counter whose counter type is [B & W Total] relates to the number of monochrome prints. That is, as the image forming apparatus 1 performs monochrome printing, this counter counts down the number of monochrome prints from the current value, and re-indicates how many monochrome prints are allowed to the user in the department. . It does not matter which function is used for monochrome printing and the paper size.

  As described above, the counter data 7 </ b> C indicates the usage amount of the image forming apparatus 1 that can be permitted for use by users in the department by a predetermined date. Hereinafter, this amount used is referred to as “usable amount”.

  The user cannot use the image forming apparatus 1 unless a part or all of the usable amount indicated in the counter data 7C of the department to which the user belongs is allocated and secured to the image forming apparatus 1. Further, the user can use the image forming apparatus 1 only within the usable amount range secured in the image forming apparatus 1.

  In FIG. 3, the allocation counter storage unit 121 of the image forming apparatus 1 stores information on the usable amount allocated and secured to the image forming apparatus 1. Specifically, allocation counter data 7D as shown in FIG. 8 is stored.

  The allocation counter data 7D includes counters (hereinafter referred to as “allocation counters”) corresponding to the 29 processes described above with reference to FIG. Each allocation counter indicates how much the user who has logged in to the image forming apparatus 1 is allowed to execute the processing related to the allocation counter. Each time the user causes the image forming apparatus 1 to execute processing, the value of the allocation counter is counted down according to the amount of processing, that is, the usage amount of the image forming apparatus 1. When the value becomes “0” or less, the user cannot cause the image forming apparatus 1 to execute the process related to the allocation counter.

  Each process related to 29 allocation counters shown in the allocation counter data 7D corresponds to each process of 29 shown in the counter data 7C of FIG. 7 and has the same meaning. The initial values of the allocation counters in the allocation counter data 7D are all “0”.

  A single job performed by the image forming apparatus 1 may include a plurality of processes. For example, a copy job includes at least two processes of scanning and printing. One process may correspond to a plurality of processes related to the allocation counters shown in FIG. For example, a full-color copy job on a large-size sheet includes two processes of scanning and printing. Among them, the scan process corresponds to only one process related to the [NumberOfOriginals] allocation counter, but the print process is [NumberOfPrints], [Copy.Total], [Copy.Total.Large], [Copy.FullColor]. ], [Copy.FullColor.Large], and [Color Total] corresponding to each allocation counter, that is, six processes. In this case, all the corresponding allocation counters count down according to the processing performed by the image forming apparatus 1. Therefore, when a five-page original is copied in full color on a large size sheet in three copies, the [NumberOfOriginals] allocation counter counts down “5”, and the remaining six allocation counters count down “15”.

  The usable amount allocation requesting unit 103 requests the intermediate authentication server 2 to allocate the usable amount of the department to which the user logged in to the image forming apparatus 1 belongs to the image forming apparatus 1.

  The timing for requesting the allocation is (1) when the user logs in to the image forming apparatus 1, or (2) the available amount necessary for executing the job instructed by the user is a necessary counter value check described later. When checked by the unit 110.

  In FIG. 4, the allocation request reception unit 204 of the intermediate authentication server 2 receives a request for allocation of the usable amount from the image forming apparatus 1.

  In response to the request, the available amount allocation unit 205 sends a part of the usable amount indicated in the counter data 7C of the department to which the user currently logged in to the image forming apparatus 1 belongs to the image forming apparatus 1 or Process to assign all. Such processing is based on the assigned prescribed amount data 7E stored in the assigned prescribed amount storage unit 213 in principle when the request source does not specify the necessary amount.

  Here, the allocation prescribed amount data 7E will be described. As shown in FIG. 9, the assigned prescribed amount data 7 </ b> E is stored in the assigned prescribed amount storage unit 213 for each image forming apparatus 1.

  The allocated specified amount data 7E indicates how much usable amount is allocated (given) to each of the 29 processes described above with reference to FIG. 7 in response to a single request from the image forming apparatus 1. Has been.

  Each process of 29 shown in the allocation prescribed amount data 7E corresponds to each process of 29 shown in the counter data 7C of FIG. 7, and has the same meaning.

  The assigned specified amount data 7E may be set according to the processing speed of the image forming apparatus 1. For example, with respect to the assigned specified amount data 7E of the image forming apparatus 1 having a high printing speed, the usable amount of processing relating to printing is set to be larger than that of the image forming apparatus 1 having a low printing speed.

  Returning to the description of the usable amount allocating unit 205, the usable amount allocating unit 205 supplies the usable amount for the image forming apparatus 1 to the image forming apparatus 1, as shown in the allocation specified amount data 7 E of the request source image forming apparatus 1. Assign. At this time, the usable amount allocation data 8A indicating the usable amount is transmitted to the image forming apparatus 1 and is logged in to the image forming apparatus 1 currently stored in the overall counter storage unit 212. The usable amount is counted down from each counter of the counter data 7C of the department to which the user belongs.

  However, when the image forming apparatus 1 designates the necessary usable amount, the necessary usable amount is allocated regardless of the allocation prescribed amount data 7E.

  Further, the usable amount allocation unit 205 stops the allocation when there is no usable amount remaining to be allocated in any of the counter data 7C. Or, allocate only the remaining amount.

  The usable amount receiving unit 104 of the image forming apparatus 1 receives the usable amount allocation data 8 </ b> A from the intermediate authentication server 2. Then, each usable amount indicated in the usable amount allocation data 8A is added to each corresponding allocation counter in the allocation counter data 7D stored in the allocation counter storage unit 121.

  As a result, a part or all of the usable amount of the user's department that is centrally managed by the intermediate authentication server 2 is allocated to the image forming apparatus 1 that is logging in the user.

  The job command accepting unit 105 transmits a job command desired by the user and execution conditions of the job (the color used for printing is any one of full color, two colors, one color, and monochrome, or is transmitted) Designation of which one of color image and monochrome image is to be used. The job command and execution condition designation may be made directly on the image forming apparatus 1 by the operation panel 10e or may be made remotely by the personal computer 4.

  Note that jobs received by the job command receiving unit 105 are executed in the order of reception. Job data of jobs waiting to be executed is accumulated in a queue, and is deleted after execution is completed.

  The access right inquiry unit 106 gives the commander of the job the access right to execute the job that the job execution control unit 108 is to execute under the processing conditions (execution conditions) indicated in the job data of the job. The intermediate authentication server 2 is inquired as to whether or not it has been registered.

  Then, the access right answering unit 206 of the intermediate authentication server 2 determines whether or not such an access right is given to the user based on the access right data 7B of the user (see FIG. 6). Then, the result is returned to the image forming apparatus 1 as the inquiry source.

  For example, when the user gives a copy job command and specifies full color as the execution condition, the access right answering unit 206 indicates that the value of the “copy” field of the access right data 7B of the user is “◯” and If the value of the “color printing” field is “◯”, it is determined that the access right is given, and a response to that effect is given. If any one of them is “x”, it is determined that the access right is not given, and the fact is answered.

  The necessary counter value check unit 110 determines which counter value (usable amount) of which allocation counter is included in the allocation counter data 7D in order to execute a job whose execution is permitted by the job execution permission determination unit 107. Just check what you need.

  For example, in order to execute a job of “job type: PC print, number of original pages: 7 pages, print destination paper size: A4, color: monochrome, number of copies: 4”, [NumberOfPrints], [ The counter value (usable amount) of each allocation counter of “Print.Total”, “Print.Black”, and “B & W Total” is required by “28”. This is obtained by referring to the print data transmitted from the command source personal computer 4 as before.

  Alternatively, in order to execute the job “job type: copy, number of original pages: 5 pages, print destination paper size: A3 (large size), color: full color, number of copies: 3”, the above-described job is executed. As you can see, the available number of the allocation counter of [NumberOfOriginals] must be “5”, and [NumberOfPrints], [Copy.Total], [Copy.Total.Large], [Copy.FullColor], [Copy.FullColor.Large ] And [Color Total] are required to have a usable amount of “15” for each allocation counter. This is determined by the paper size, color condition, and number of copies specified by the user, and the number of pages of the original read by the scanner unit 10f.

  When the usable amount necessary for the job received by the job command receiving unit 105 is obtained in this way, as described above, the usable amount allocation requesting unit 103 appropriately requests the allocation of the usable amount. This is performed for the authentication server 2.

  Specifically, when the necessary usable amount obtained by the necessary counter value check unit 110 is larger than the usable amount indicated in the allocation counter data 7D stored in the allocation counter storage unit 121 (that is, If only the usable amount currently allocated to the image forming apparatus 1 cannot compensate for the necessary usable amount), the shortage is requested to the intermediate authentication server 2. For example, when the values of the allocation counters indicated in the allocation counter data 7D are all “0”, the necessary usable amount obtained by the necessary counter value check unit 110 is requested as it is.

  The necessary usable amount (usable amount obtained by the necessary counter value check unit 110) acquired from the intermediate authentication server 2 as necessary and assigned to the image forming apparatus 1 is reserved for the job. The The reservation is not canceled unless a predetermined event occurs, such as when the user cancels the job or a failure occurs. Therefore, the reserved usable amount is not consumed for other jobs or returned to the intermediate authentication server 2 unless a predetermined event occurs.

The job execution permission / non-permission determining unit 107 determines whether or not the job according to the user command may be executed based on whether or not the following (Requirement 1) and (Requirement 2) are satisfied.
(Requirement 1) The intermediate authentication server 2 has received a reply that the access right to execute the job is given to the user.
(Requirement 2) The available amount necessary to execute the job is reserved.

  Only when both requirements are satisfied, it is determined that the job may be executed, and when neither of the requirements is satisfied, it is determined that execution is not permitted.

  When the job execution control unit 108 determines that the job can be executed, the job execution control unit 108 executes each hardware and software as usual so that the job is executed according to the execution condition. Control. On the other hand, if it is determined that execution is not permitted, the job is canceled.

  Each time the process included in the job is executed, the allocation counter corresponding to the process counts down. Thus, if the job completes normally, all the available amount reserved for that job is consumed.

  The remaining usable amount return unit 109 performs processing to return (return) a part or all of the usable amount allocated from the intermediate authentication server 2 to the intermediate authentication server 2.

  Such processing is performed when (A) the usable amount necessary for the latest job is obtained by the necessary counter value check unit 110 and the necessary usable amount is reserved for the job, or (B) the user When the user logs out.

  In both cases (A) and (B), the remaining available amount return unit 109 is currently being executed out of the available amounts indicated in the allocation counter data 7D stored in the allocation counter storage unit 121. Alternatively, the usable amount that is not reserved for any job waiting to be executed is returned. That is, the portion of the usable amount allocated from the intermediate authentication server 2 that has not been determined for which job is consumed is returned.

  At this time, the remaining usable amount return unit 109 sends the data indicating the usable amount to be returned and the department ID of the department to which the currently logged-in user belongs to the intermediate authentication server 2 as the remaining usable amount data 8B. Send. Further, the allocation counter data 7D is updated so that the usable amount secured in the image forming apparatus 1 without being returned is indicated.

  The remaining use permission amount receiving unit 207 of the intermediate authentication server 2 receives the remaining usable amount data 8B from the image forming apparatus 1. Then, the usable amount indicated in the remaining usable amount data 8B is added to each counter corresponding to the counter data 7C of the department related to the remaining usable amount data 8B stored in the overall counter storage unit 212. . In other words, a usable amount that has been allocated to the image forming apparatus 1 but is not consumed is returned.

  FIG. 10 is a flowchart for explaining an example of the overall processing flow of the image forming apparatus 1, and FIG. 11 is a flowchart for explaining an example of the overall processing flow of the intermediate authentication server 2.

  Next, the overall processing flow of allocation counter management in the image forming apparatus 1 and the overall processing flow of counter management in the intermediate authentication server 2 will be described with reference to the flowcharts of FIGS. 10 and 11. .

  In FIG. 10, when the image forming apparatus 1 receives the input of the user ID and password of the user who intends to use the image forming apparatus 1 (# 1), the intermediate authentication server 2 performs the user authentication of the user. (# 2).

  If authentication is not obtained (No in # 3), the user is prompted to input the user ID and password again.

  If the authentication is obtained (Yes in # 3), the user is permitted to log in and requests the intermediate authentication server 2 to allocate the usable amount (# 4).

  When the usable amount allocation data 8A is received from the intermediate authentication server 2, each corresponding usable amount indicated in the usable amount allocation data 8A is added to the allocation counter of each process of the allocation counter data 7D (see FIG. 8). (# 5).

  When a job command is given from the user (Yes in # 7), the intermediate authentication server 2 is inquired as to whether or not the user has access right (# 8), and the usage necessary to execute the job is used The possible amount is checked (# 9).

  If the necessary amount of the usable amount is allocated to the image forming apparatus 1 without being reserved for any other job (Yes in # 10), the necessary amount is used. The available amount is reserved for the job, and the job is executed in sequence (# 13) on condition that the access right is confirmed (Yes in # 12). If the job is executed normally, the usable amount of the reserved job is consumed (# 14).

  On the other hand, if a part or all of the necessary usable amount is insufficient (No in # 10), the intermediate authentication server 2 is requested to allocate the insufficient amount (# 11). If the necessary amount of the usable amount can be reserved for the job, the job is sequentially executed (# 13) on condition that the access right is confirmed (Yes in # 12). . Also in this case, if the job is executed normally, the usable amount of the reserved job is consumed (# 14).

  When the user logs out (Yes in # 6), the usable amount that is not reserved for any job currently being executed or waiting for execution is returned to the intermediate authentication server 2 (# 15).

  In FIG. 11, when the intermediate authentication server 2 receives some data from the image forming apparatus 1 (# 21), the intermediate authentication server 2 executes the following processing according to the type of the data.

  When the user ID and password are received, that is, when a request for user authentication is received (Yes in # 22), the general authentication server 3 is caused to execute user authentication (# 23), and the result is sent to the requesting image forming apparatus 1. (# 24).

  When the data relating to the request for allocation of the usable amount is received (Yes in # 25), when the amount is not specified, the allocation specified amount data 7E corresponding to the requesting image forming apparatus 1 (see FIG. 9). ) Is checked (# 26), and the available amount corresponding to the checked assigned amount is calculated from the available amount stored in the counter data 7C of the department to which the user of the image forming apparatus 1 belongs. The image forming apparatus 1 is assigned (# 27). When the amount is designated, the usable amount as designated is assigned to the image forming apparatus 1 (# 27). If there is not enough, the allocation is cancelled. Alternatively, a part or all of the remaining usable amount is allocated.

  When data related to the access right inquiry is received (Yes in # 28), the access right (see FIG. 5) of the user of the image forming apparatus 1 as the inquiry source is checked (# 29), and the result is answered (#). 30).

  When the remaining usable amount data 8B is received (Yes in # 31), the usable amount indicated therein is added to the counter of the original counter data 7C (# 32).

  The intermediate authentication server 2 appropriately executes these processes until the service is stopped.

  FIG. 12 is a flowchart for explaining an example of the flow of processing of the image forming apparatus 1A and the intermediate authentication server 2 when the image forming apparatus 1A is used.

  Next, the processing flow of the image forming apparatus 1A and the intermediate authentication server 2 when the user UA belonging to the same department K uses the image forming apparatus 1A will be described with reference to the flowchart of FIG.

  Currently, no one is logged in to the image forming apparatus 1A, and there is no job being executed or no job waiting to be executed. The initial value “0” is stored in each allocation counter of the allocation counter data 7D of the image forming apparatus 1A. The intermediate authentication server 2 stores data indicating the usable amount N as the counter data 7C of the department K.

However,
Usable amount N = (n1, n2,..., N29)
The elements n1, n2,..., N29 indicate the usable amounts of the processes of [NumberOfOriginals], [NumberOfPrints],..., [B & W Total] in FIG. The same applies to each element included in the usable amounts X, Y, and Z described later.

  When the user UA inputs the user ID and password to the image forming apparatus 1A, the image forming apparatus 1A requests the intermediate authentication server 2 to perform user authentication of the user UA (# 101 in FIG. 12).

  When the intermediate authentication server 2 accepts the request (# 201), it causes the general-purpose authentication server 3 to execute user authentication of the user UA (# 202). The image forming apparatus 1A is answered (# 203).

  When the image forming apparatus 1A receives a response indicating that the user is a legitimate user (# 102), the image forming apparatus 1A recognizes the login of the user UA and requests the intermediate authentication server 2 to allocate a usable amount (##). 103). Here, it is not specified how much usable amount is required.

  When the intermediate authentication server 2 accepts the request (# 204), it checks the allocation prescribed amount data 7E of the department K and assigns the usable amount indicated thereto to the image forming apparatus 1A (# 205). Hereinafter, the usable amount allocated to the image forming apparatus 1A in Step # 205 is referred to as “usable amount X”. At this time, the usable amount X is subtracted from the counter data 7C of the department K (# 207).

  When the image forming apparatus 1A receives the allocation of the usable amount X (# 104), the usable amount X is added to the allocation counter data 7D (# 105). Since the initial values of the allocation counters in the allocation counter data 7D are all “0”, the allocation counter data 7D indicates the usable amount X here.

  When a job command is given from the user UA (# 106), the usable amount necessary for the job is obtained (# 107), and the usable amount that is currently allocated to the image forming apparatus 1A and is not reserved is obtained. If it is equal to or greater than the necessary usable amount, the necessary usable amount is reserved from among the necessary usable amounts, and execution of the job is started (# 108). The remaining usable amount is returned to the intermediate authentication server 2 before or after the start of job execution (# 109).

  When the job is completed normally (# 110), the usable amount allocated to the image forming apparatus 1A becomes zero.

  When the intermediate authentication server 2 accepts the return of the usable amount (# 207), it returns it to the counter data 7C of the department K (# 208).

  When the image forming apparatus 1A newly receives a job command, the image forming apparatus 1A obtains a usable amount necessary for the job (# 113), and if the corresponding usable amount is not currently allocated to the image forming apparatus 1A, an intermediate This is requested to the authentication server 2 (# 114).

  The intermediate authentication server 2 allocates the usable amount of the department K to the image forming apparatus 1 by the requested amount (# 209, # 210).

  The image forming apparatus 1A executes the job using the available amount allocated this time. Hereinafter, until the user UA logs out or until the usable amount of the department K that is centrally managed by the intermediate authentication server 2 is insufficient, the usable amount is appropriately reduced from the intermediate authentication server 2 by the amount necessary for job execution. It is allocated to the image forming apparatus 1 and consumed.

  According to the present embodiment, the image forming apparatus 1 secures only the usable amount necessary for the commanded job, and returns the usable amount not currently required to the intermediate authentication server 2. Moreover, securing and returning are performed immediately when the usable amount necessary for executing the job is found. Therefore, the usable amount can be efficiently exchanged between the image forming apparatuses 1 and the convenience for the user can be improved as compared with the conventional case. In addition, since the intermediate authentication server 2 manages the usable amount in a centralized manner, the use of the image forming apparatus 1 can be strictly limited.

  In this embodiment, the case where a user account that performs user authentication in the general-purpose authentication server 3 has been described as an example. However, the user account that the image forming apparatus 1 itself performs user authentication, that is, a local user account (for example, a temporary image) The present invention is also applied to a case where a guest public user account that uses the forming apparatus 1, an administrator account that performs overall management of the image forming apparatus 1, or a box administrator account that manages boxes is used. Can be applied.

  Alternatively, the present invention can also be applied to a case where a user logs in using a user account (so-called group account) commonly used by members of a department.

  In the present embodiment, for simplicity of explanation, the case of single-sided copying has been described as an example. However, the present invention can also be applied to the image forming apparatus 1 having a special copying function. In this case, the rules for consumption of the usable amount can be arbitrarily determined. For example, in the case of double-sided copying, only “1” may be consumed per copy in accordance with the number of sheets consumed, or one copy is a copy of two pages. In view of this, only “2” may be consumed. Similarly, in the case of 2-in-1 copying, the usable amount may be consumed according to the number of copies, or the usable amount may be consumed according to the number of copied pages.

  When the image forming apparatus 1 displays the information of the job instructed by the user, the image forming apparatus 1 displays the information depending on whether it is waiting to receive the allocation of the usable amount from the intermediate authentication server 2 or has already received the allocation. May be different.

  The result of the processing by the necessary counter value check unit 110 can be applied as follows. For example, it is assumed that the image forming apparatus 1 receives a job for copying eight copies of a 20-page document in a state where only a part of the necessary usable amount can be secured. When comparing the available amount currently allocated with the available amount required for the job, which is obtained by the necessary counter value check unit 110, it is assumed that the former is only one-fourth of the latter.

  In this case, the image forming apparatus 1 presents that the number of copies is changed to 1/4, that is, 2 copies. Or, it is suggested to change to 4in1.

  In addition, the entire image processing system GSS, the image forming apparatus 1, the intermediate authentication server 2, or the configuration of each unit, the processing content, the processing order, the configuration of the database, and the like can be appropriately changed in accordance with the spirit of the present invention.
