Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of reading operation mode data registered in a storage medium (for example, an IC card) and collectively setting modes defined by the data. For more information on copying machines, please see
Concerning saving mode data when an abnormality occurs.

[Conventional technology]

The operation mode of the copying machine (e.g. copy magnification;
1.2 times, exposure amount: standard, copy paper size: A4. The number of copies to be made: 14 copies, etc. (a mode frequently used by the user of the IC card) is stored, the stored mode data is read into the control means of the copying machine, and the operation mode specified by the data is set. , it has been proposed to set them all at once on copying machines.

[Problem that the invention seeks to solve]

When the above IC card is set in a copying machine and the copying machine is used under the mode specified by the data on the card,
Problems such as paper jams may occur.

In the above case, after the problem is resolved (or by using another copying machine), the same mode (operation mode other than the number of copies, such as copy magnification, exposure amount, copy paper size, etc., must be the same). , there is a desire to perform residual copying. For example, if "14 sheets" is set as copy number data, which is one of the mode data, and a paper jam occurs on the third sheet, it is desired to copy the remaining 12 sheets.

Conventionally, in such a case, it was necessary to set the mode from the beginning by operating keys on the operation panel of the copying machine. In other words, by using an IC card,
It was not possible to set various operating modes all at once. This is because the operation mode registered in the IC card is the original mode, and the number of copies is "14 (in the above case)".

The present invention has been made in view of the above circumstances, and is based on an IC
The mode for the remaining copy operations can be set all at once depending on the card.

[Means and effects for solving the problem] The present invention saves data on the operating mode when a trouble occurs to an IC card.

That is, a copying machine that can be connected to a storage medium according to the present invention includes: a connection means with a storage medium that stores data regarding an operation mode of the copying machine; and a means for reading data stored in the storage medium and performing an operation using the data. mode control means for setting a prescribed operating mode in the copying machine; detection means for detecting an abnormality in the copying machine; and data evacuation control means for evacuation.

With this configuration, when a trouble occurs, data on the number of uncopied sheets at the time of the trouble is saved to the IC card. Therefore, using the IC card, the mode for the remaining copying operations can be set for all copying machines (the copying machine in which the problem has been resolved, or another copying machine).

Right, in the above, not only the uncopied number data,
Data for other types of operation modes may also be saved all at once.

(Description of Operation) (A) General Description FIG. 4 is a flowchart showing the main routine of processing by the control CPU constituting the main control section 201.

The control CPU starts processing by turning on the main switch, for example, and first sets an initial state (Sl).

Next, set the internal timer that defines the time for one routine (S3), and after executing each process from S5 to S17,
At step 9, the process waits for the internal timer set at step S3 to end, and then returns to step S3 to repeat the process.

(1) S5 This is a step in which the operation mode of the copying machine is returned to the "predetermined initial state" when predetermined initialization conditions such as input of the all clear key 95 are satisfied. Note that the "initial state" to be returned to is selected differently depending on whether the IC card 200 is set or not.

Details of the processing will be described later.

(2) S7 This is a step for controlling the copy operation. Note that in this step, an auto clear timer related to the initialization condition is set.

Details of the processing will be described later.

(3) S9 This is a step for controlling changes in the operating mode due to attachment and detachment of the IC card.

Details of the processing will be described later.

(4) Sll The operating mode registered on the inserted IC card is
If it cannot be handled because it is outside the capability of the copying machine (for example, the maximum magnification that can be set on the copying machine is 1.420x,
This is a step to issue a warning if the magnification registered in the IC card is greater than 1.420 times.

Details of the processing will be described later.

This is a step of controlling the display of the number of copies to be made. Furthermore, if the number of copies read from the IC card exceeds 99 copies, which is the maximum number of copies processed by this copier, the control to enable continuous copying operations is also processed in this step. be done.

Details of the processing will be described later.

(6) S15 This is a processing step when a paper jam occurs in the copying machine. In this step, mode data saving processing is executed when an IC card is set at the time of a paper jam.

Details of the processing will be described later.

(7) S17 This is a step for controlling other processes such as key manual processing, temperature control, and communication with other CPUs.

Since this is well known, detailed explanation will be omitted.

(B) Description of each subroutine (1) Initial routine FIG. 5 is a flowchart showing details of S5.

If any key manual processing is required (S101; Y
ES), starts the auto clear timer (S10
3) When the timer expires (3105; YES), a predetermined initial state J (Sill or 5113) is set.

Also when the all clear key 95 is pressed (S107
;YES), the same is true. Note that the auto clear timer is also started each time a copy operation ends (S247).
:Refer to copy operation routine).

In addition, in the above, the "predetermined initial state" means, when an IC card is set (S109; YES), a state defined by data registered in the card (31
13), and on the other hand, if the IC card is not set (S109; NO), as in Sl (Fig. 4),
This is the "basic initial state" (Sill).

Note that when the registered data of the IC card is adopted as the above-mentioned "predetermined initial state" (S113), the number of copies specified by the data is the maximum number of copies that can be processed in one batch by this copying machine. If the number exceeds 99 (S 115; Y
ES) should set the over flag 3117), 51
19 is executed. "Copy number processing" is a process to enable continuous copying of the set number of copies even if the set number of copies exceeds 99.The IC card insertion/removal routine will be explained later. Details will be explained in .

(2> Copy Operation Routine FIGS. 6(a) and 6(b) are flowcharts showing the details of S7.

8201 to 8203 are steps for processing the start of copy operation control. That is, in response to turning on the print switch 71 (S201), a copy start flag is set (S203).

5205 to 5219 are processes at the start of a copy operation.

That is, on the condition that the copy start flag is set (S205; YES), the main motor, developing motor, charging charger, and transfer charger are turned ON.
, lower the copy start flag, and set timer A and timer B.
is started (S207).

Next, the paper feed roller clutch of the paper feed port corresponding to the selected paper size is turned on (3211, 5215) to start feeding paper from the cassette, and on condition that the timer A ends (S21?) , the paper feed roller clutch is turned off (S219).

5221 to 5231 are processing steps during a copy operation.

That is, on the condition that the timer B ends (S221),
Generates a scanning signal to the optical system control unit 202 (3223
). As a result, the optical system starts exposure scanning.

Next, a timing signal from the optical system is input (S2
25; YES), the clutch of the timing roller 73 is turned on to start feeding paper to the transfer section, and at the same time, timer C is started (S227).

Next, on the condition that the timer C ends (S229;
YES), charger, scan signal.

Turn off the timing roller clutch (S231).

5233 to 5241 are processing steps at the end of the copy operation.

That is, in response to the start of the return of the optical scanner (S
233; YES), it is determined whether all multi-copying has been completed (3235.).

If it is determined that multi-copy is completed (S235; YE
S) sets the developing motor and transfer charger to 0FFL and starts timer D (5241), on the condition that the manual input of the fixed position signal from the optical system control unit 202 is required (3239).

On the other hand, if the multi-copy is not completed in 5235,
A copy start flag is set (S237) to prepare for the next copy operation for the same document.

8243 to 5247 are steps for processing the end of copy operation control.

That is, on the condition that the timer D ends (S243; Y
ES), main motor to 0FFL (S245), and
An auto clear timer is started (S247). The auto clear timer is used as one of the initialization conditions in the initial routine.

Note that 5249 is a step of outputting the above-mentioned processed signal.

(3) IC card insertion/removal routine FIGS. 7(a) to 7(C) are flowcharts showing the details of S9.

8301 to 5315 are processes performed when inserting an IC card.

That is, when an IC card is set in the card insertion section 70 of the copying machine (S301; YES), first, it is determined whether or not the interrupt mode is registered in the IC card.
Based on the setting of the IC card, it is determined whether the interrupt mode should be set in the copying machine (S303).

If interrupt mode is registered (3303; YES)
executes an interrupt. That is, if the copying machine is in the copying state at the time of the interrupt (S305; YES), the copying state is canceled (S307), and the various operation modes at the time of cancellation are saved in the memory within the copying machine body (3309).
. On the other hand, if the copying machine is not in the copying state (S305; N
o) The various operation modes set for the copying machine are saved in the memory within the copying machine main body (S311).

If the interrupt mode is not registered in the IC card in step 5303, the process advances to step 5313, and similarly to step 5305, it is determined whether the copying machine is in the copying state. As a result of the determination, if it is in the copy state, set the copy completion wait flag (5315), jump from S, 317 to 5331, and proceed to 5333. On the other hand, if it is determined in 5313 that it is not in the copy state, 5309 and 5311
Similarly, proceed to 5317.

Steps 8317 to 5331 are steps for setting the copying machine to various operation modes defined by data read from the IC card.

First, it is determined whether there is data in the remaining number of copies area of the IC card (see Trouble Routine) (
5317).

If there is no data in the remaining copies area,
The mode specified by the data registered in the IC card (mode data that specifies the number of copies, exposure amount, copy magnification, and paper size, and is registered in advance through predetermined manual means) is activated by the copying machine. Please set it to 5319)
Also, the set number of copies is displayed on the number display section 72 (S321).

On the other hand, if it is determined in step 5317 that there is data in the remaining number of copies area, the process advances to 5323, and the data saved in the remaining number of copies area of the IC card in the trouble routine described later is used as the number of copies data. settings on the copier, as well as exposure intensity, copy magnification,
Data registered in the IC card is set as paper size mode data (S323). Further, the number of remaining copies is displayed on the number display section 72 (S3
25).

Next, it is determined whether the number of copies set in the copying machine in 5319 or 5323 is greater than or equal to the batch processing capacity range of this copying machine (up to 99 copies in this embodiment).
), if the processing capacity is exceeded, the above-mentioned "copy number processing" is executed. In other words, set the over flag to 5.
329), divide the number of copies set above by 99, which is the maximum number of copies to be processed in one batch, and write the quotient in Memo 'IIB.
The remainder is assigned to memory C (5331), and the number "99" is displayed on the number display section 72 (S33).
1). This is a process for continuing to copy the remaining number of sheets after the copying of 99 sheets, which is the maximum number of sheets to be processed in one batch, is completed (see the number of sheets display routine).

8333 to 5353 set the IC card data to the copying machine when the copying machine is in the copying state (see S30, 3.5313.5315) when setting an IC card with no interrupt mode registered. , is a step in which the processing is delayed from the time when the IC card is set.

That is, when the copy state ends (S333;
YES), if the copy completion wait flag is set (S335; YES, see 5315), the copy completion wait flag is removed (8337), and the mode specified by the card data is set to the copying machine ( S 339～
5353). Note that the processing of 5339 to 5353 is the same as that of 5317 to 5331 described above.

Steps 5355 to 5361 are processes performed when the IC card is pulled out from the card insertion section 70 of the copying machine.

That is, if removal of the IC card is detected (335
5; YES) sets the "initial state" to the copying machine (S
359 or 5361). Here, as the "initial state", if an interrupt mode is registered in the removed IC card (S357; YES), the mode that was set in the copier immediately before the card was inserted is selected (S357; YES).
359: see 5309.5311 above), on the other hand, if the interrupt mode is not registered in the IC card (S
357; No) It, the "basic initial state" which is the same as the mode set in St (FIG. 4) is selected.

(4) Overspec Warning Routine FIG. 8 is a flowchart showing details of the Sit.

That is, when an IC card is set in the copying machine (S401; YES), if the number of copies read from the IC card into the copying machine exceeds the maximum batch processing number (99 copies) (S403). ;NO), or
If the read copy magnification exceeds the maximum copy magnification (1,420 times) that can be set on the copier (3405; No
>, or if the settable minimum copy magnification is not reached (S407; NO), an overspec warning display LE is displayed.
D95a is blinked (S411) to issue a warning.

(5) Number of sheets display routine FIGS. 9(a) and 9(b) are flowcharts showing details of S13. In this routine, the number of copies displayed on the number display section 72 is decremented by "1" in synchronization with the scanning end timing of the optical system, in other words, each time each image forming process is completed, and the result is Execute the appropriate processing.

First, in synchronization with the scan end timing of the optical system (S
501 ; YES), subtract "1" from the numerical value displayed on the sheet number display section 72 (5503), and determine whether or not the sheet number display after the subtraction has become "0" (S505).

If it is determined in step 5505 that the number of sheets displayed is "0", it is further determined whether or not an over flag is set (S507). As mentioned above, the over flag is
This is a flag that is set when the copy number data read into the copier from the IC card exceeds 99 copies, which is the maximum batch processing number of the copier (S 117.532
9.5351.5537).

If it is determined in 5507 that the over flag is set, the process proceeds to 5509, where the numerical data of memo 'JB is subtracted by 1 degree, and the numerical value after the subtraction is assigned to memo QB. "quotient" obtained by dividing the copy number data read from the card by the maximum number of copies processed in one batch "99"
is memorized.

Therefore, the decrement of the numerical data in memory B at 5509 corresponds to the end of copying 99 sheets.

As a result of the subtraction in step 5509 above, if the numerical value stored in the memory becomes "0"(S511; YES),
To reset the over flag (5513), proceed to 3515. Note that the case where the value in memory B becomes "0" is the case where the number of remaining copies becomes 98 or less.

5515 is a step of determining the numerical data in memory C. The memory C stores the "remainder" obtained by dividing the copy number data read from the IC card by the maximum batch processing number "99". In other words, memory C
, the number of remaining copies of 98 or less is stored.

In the above 5515, the numerical value of the data of memo IJc is "0"
In other words, if the remaining number of copies is between 1 and 98, the number is displayed on the number display section 72 (S517) and a copy start flag is set (3523). This continues the remaining copying.

Note that if the value stored in memory B is not "0" in step 5511, that is, if there are still 99 or more copies left, 99 is displayed on the number display section 72 (3521); Set the copy start flag (S52
3), continue with the remaining copies.

On the other hand, if the over flag is not set in 5507, or if the value stored in Memo'JC is "0" in 5515, the number of copies read from the IC card is Since all the copies have been completed, the process goes to 5529 and returns to the original number of copies (
The number of copies registered in the IC card) is displayed on the number display section 72, and the process proceeds to 5531.

Steps 5531-S533 are steps for clearing the data in the remaining copy number area (see trouble routine) of the IC card.

That is, when copying of the number of sheets read from the IC card (the number of sheets registered on the card or the number of sheets stored in the remaining copy area of the card) has been completed (S507; YES.

(or S515; YES), the data in the remaining copy number area of the IC card is cleared (3533). This prevents malfunctions in step 5317 (IC card insertion/removal routine).

5535 to 5539 are processes when the number of copies read from the IC card in 5529 exceeds the maximum batch processing number of the copier, and 5327 to 5331
This is the same process as (IC card insertion/removal routine).

As mentioned above, in this number of copies display routine, if the number of copies read from the card into the copier exceeds 99, which is the maximum number of copies processed by the copier, copy processing is performed in units of 99. The process is repeated for the number of times stored in memory C, and then the remaining copies stored in memory C are processed.

This makes it possible to continuously copy the number of sheets that have been read.

(6) Trouble Routine FIG. 1O is a flowchart showing the details of S15.

8601 to 5609 are steps for detecting a paper jam.

First, in synchronization with the paper feeding timing (S601)
, start timer X) L (5603), and stop timer X in synchronization with the paper ejection timing (S605) (S607). The value of timer X is set to a sufficient time from when the paper is fed until it is ejected. Therefore, if timer X ends (5609; Y
ES) is a case where a paper jam occurs.

If the paper jam occurs, the trouble display LED 7
3 is lit (5611), and if the IC card is set (S613; YES), the remaining number of copies is saved in the remaining number of copies area of the IC card (S615).

This copying machine is controlled in the manner described above.

<Effects> As described above, the present invention can prevent paper jams, etc. when a copying machine is set to an operation mode defined by data registered in an IC card. When a trouble occurs, the mode data at the time of the trouble is saved in the IC card.

As described in detail in the embodiments, according to the present invention, data on the number of uncopied sheets when a trouble occurs is saved to the IC card, so the mode settings for the remaining copy operations can be changed using the IC card. It can be executed all at once.
