Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a copying machine that can be connected to a storage medium such as an IC card, and more particularly relates to setting an operation mode when a card is inserted or removed.

[Conventional technology]

Various operation modes (
2. Description of the Related Art Copying machines have been provided in which it is possible to set modes that define the operation mode of the copying machine, such as copy magnification, exposure amount, copy paper size, number of copies, etc.

Additionally, there are copying machines that can be set to an "interrupt copy mode." This means that when a copying machine is used in a specific operation mode, a mode different from the specific mode is temporarily set on the copying machine, and after copying in the different mode is completed, the specific mode is set. This allows the modes to be set all at once again.

In addition, the operation mode of the copying machine (for example, copy magnification: 1.2x, exposure amount: standard, copy paper size: A4) is written on the IC card.
．． It has been proposed to store the number of copies (a mode frequently used by the user of the IC card, such as 14 copies, 9, etc.), and to collectively set the stored operation mode in the copying machine.

[Problem that the invention seeks to solve]

When using the above IC card in a copy machine,
The problem is the relationship with the mode that was set on the copier before the card was set.

The first problem is whether or not to immediately set the mode defined by the data on the card in the copying machine by setting the card.

The second problem is what mode the copying machine should be in when the card is removed from the copying machine.

The present invention is intended to solve the above two problems, and is intended to minimize the number of operations required for both the IC card user and other users.

[Means and effects for solving the problems] The present invention
By setting the "interrupt copy mode" by setting the C card, the mode specified by the data on the card is set in the copier, and when the card is removed, the mode set before the card was set is set in the copier. It is to revive the.

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 the operation mode of the copying machine; and a connection detection device that detects a connection state between the copying machine and the storage medium. means, save control means for saving data of an operation mode set in the copying machine before the detection into a predetermined storage means when the connection state is detected; mode setting means for setting the mode to a mode defined by the mode data stored in the connection state; In this case, the apparatus further includes mode control means for providing the saved mode data to the mode setting means.

With this configuration, when an IC card is inserted, the mode defined by the data on the card is set in the copying machine, and when the card is removed, the mode that was set before the card was inserted is restored.

Note that in the above, data indicating whether or not "interrupt mode" should be set may be registered in the IC card, and the above operation may be made to function only when the data is present.

(Operation Description) [A] General Description FIG. 4 is a flowchart showing a 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 the l routine (33), 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.

This is a step for controlling copy operations. 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.

(5) S13 This is a step for 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) Sll key This is a step for controlling other processes such as manual processing, temperature control, and communication with other CPUs.

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

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

If any key manual processing is required (S101; YE
S), starts the auto clear timer (S103)
, When the timer ends (S105; YES), a predetermined initial state J (Sill or 5113) is set.Also when the all clear key 95 is pressed (S107; Y
ES), the same is true. In addition, the auto clear timer is
It is also started every time a copy operation ends (see S247: copy operation routine).

In addition, in the above, “predetermined initial form!!!J” means IC
If a card is set (S109; YES), the state specified by the data registered on the card (
On the other hand, if the IC card is not set (S109.NO), it is in the "basic initial state" (Sill) as in Sl (FIG. 4).

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 99, which is the maximum number of copies processed by this copying machine. (S l 15 ; Y
ES) should set the over flag in S11? ), 51

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

8201 to 5203 are steps for processing the start of copy operation control. That is, in response to the print switch 710 being turned on (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.
L, lowers the copy start flag and starts timer A and timer B (S207).

Next, the paper feed roller clutch of the paper feed port corresponding to the selected paper size is turned on (S211, S215) 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 (S223
). 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 the timer C is turned on.
is started (S227).

Next, on the condition that the timer C ends, (3229; Y
ES), charger, scan signal.

Turn off the timing roller clutch (8231).

8233 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 (3
233; YES), it is determined whether all multi-copying has been completed (S235).

If it is determined that the multi-copy is completed (3235; YES
) 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 (S239).

On the other hand, if it is determined in step 5235 that multi-copying is not yet completed, a copy start flag is set (S237) to prepare for the next copying 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), sets the main motor to 0FFL (3245), and starts the auto clear timer (324?).

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.

5301 to 5315 are processes when inserting a jC card.

That is, when an IC card is set in the card insertion section 70 of the bivot machine (S301; YES), first check whether the interrupt mode is registered in the IC card. Based on the setting, 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 (3305: 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 main body (S309).
. 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 copying state, set the copy completion wait flag (5315), jump from 5317 to 5331, and proceed to 8333. On the other hand, if it is determined in step 5313 that the copy state is not in effect, the process proceeds to step 3317 in the same way as steps 5309 and 5311.

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) (
S317).

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 set copy number by 99, which is the maximum number of copies to be processed in one batch, and assign the quotient to memory and the remainder to memory C. 5331),
The number "99" is displayed on the sheet number display section 72 (S331). This is a process to continue copying the remaining number of sheets after the copying of 99 sheets, which is the maximum number of sheets for batch processing, is completed. (see display routine).

3333 to 5353 set the IC card data to the copying machine when the copying machine is in the copying state (see S 303.5313.5315) when setting an IC card with no interrupt mode registered. This 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), remove the copy completion wait flag 5337), set the copying machine to the mode specified by the card data (5337); 3339~$3
53). Note that the processing in steps 5339 to 5353 is performed in step S3 above.
It is the same as 17-5331.

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 (S3
55; YES) sets the "initial state" to the copying machine (S359 or 5361). Here, "initial state"
If an interrupt mode is registered in the removed IC card (S357; YES), the mode that was set in the copying machine immediately before the card was inserted is selected (S359: see 5309.5311 above). ,on the other hand,
If no interrupt mode is registered in the IC card (S357; No), the "basic initial state" which is the same as the mode set in step 31 (FIG. 4) is selected.

(4) Overspec Warning Routine FIG. 8 is a flowchart showing the details of S11.

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 (S405.NO
), or if the settable minimum copy magnification is not reached (S407; No>, an overspec warning display LE
D96a blinks (5411) 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), the numerical value displayed on the sheet number display section 72 is subtracted by 1 degree (S503), and it is determined whether or not the sheet number display after the subtraction has become "0" (S505).

If it is determined in 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 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 117.5).
329.5351.5537).

If it is determined in 5507 that the over flag is set, the process advances to 5509 and the numerical data in memory B is stored.
Subtract 1° and assign the value after the subtraction to the memory. Memory B stores a ``quotient'' obtained by dividing the copy number data read from the card by the maximum batch processing number ``99''.

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),
Reset the over flag (S513), S515
Proceed to. 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.

If it is determined in step 5515 that the numerical value of the data in memory C is not "O", in other words, if the number of remaining copies is 1 or more and 98 or less, the numerical value is displayed on the number display section 7.
5517) and set the copy start flag (
S 523). This continues the remaining copying.

In addition, in the above step 5511, if the value stored in the memo 'JB is not "0", that is, if there are still 99 or more copies left, 99 should be displayed in the number display section 72 (5521). , set the copy start flag (S5
23), continue with remaining copies.

On the other hand, if the over flag is not set in step 5507, or if the value stored in memo IJc is "0" in step 5515, all the copies read from the IC card are Since this is the case where the copy has been completed, the process goes to 5529 and 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.

5531-3533 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 (3507; YES.

or 3515; YES), the data in the remaining copy number area of the IC card is cleared (S533). 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 copying machine exceeds 99 copies, which is the maximum number of copies processed by the copying machine, the copying process is performed in units of 99 copies. is repeated the number of times stored in memo U-B, 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)
, timer X is started) (S603), and timer X is stopped in synchronization with the paper ejection timing (3605) (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 expires (3609
;YES)+t, this is the case when a paper jam occurs.

If the paper jam occurs, the trouble display LED 7
3 is lit (3611), 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.

The following is a margin. [Effects] As described above, in the present invention, when an IC card is inserted, the mode registered in the card is set. Additionally, when the card is removed, the copying machine restores the mode that was set before the card was set.

As described in detail in the embodiments, according to the present invention, the mode desired by the card user is set by the simple operation of setting an IC card, and when the card is pulled out, the mode is set for use before the card is inserted. Since the mode desired by the user is set, it is convenient for both parties, and copy mistakes are also prevented.
