Abstract

PURPOSE:To set an operator's desired magnification value by setting a magnification value registered in a 2nd storage means regardless of the code to which the magnification value is made to correspond under the condition of a specific data load command. CONSTITUTION:A main control part 201 is connected to an IC card connector 203 through a data bus 205 to transmit/receive data to/from an IC card 200 and also connected to the driving circuit of a display part 204 such as a two- digit or four-digit magnification indication part, thereby making various displays corresponding to the operation states, etc., of the copying machine. Therefore, when copy magnification is set by loading magnification value data from the IC card 200, a fixed magnification code is unselected.

In the above, the plurality of fixed magnification value data are stored in a predetermined memory (
(hereinafter referred to as "first memory").

When setting a desired fixed magnification in the copying machine, a code for the magnification value is input using a key switch corresponding to the code. Note that the presence or absence of a code input can be determined by, for example, lighting up a display LED placed near the key switch.

(2) Modes related to copying operations, such as copying magnification, copying paper size, number of copies per original, exposure amount, etc., are registered, and the registered modes are sent to the copying machine all at once. A system for configuring is proposed.

For example, by registering the operation mode on an IC card,
A system that sets the above operating modes all at once by setting the C card in the copying machine, or a system in which the operating modes are registered in the memory of the copying machine under program mode and the above operating modes are set all at once in program call mode. system, etc. Hereinafter, the memory for the operation mode-batch registration will be referred to as "second memory".

In either case, the magnification value data is stored in association with predetermined code data.

[Problem that the invention seeks to solve]

As described above, the magnification value data is stored in association with the code data.

Therefore, when the mode data in the second memory is loaded into the copying machine, the code data is also loaded together with the magnification value data.

Conventionally, a control CPU of a copying machine reads a magnification value tab from a first memory based on loaded code data and sets a copy magnification defined by the data. Further, the indicator LED corresponding to the loaded code is lit.

However, the magnification value associated with the same code is
The first memory and the second memory may be different. Such a case occurs, for example, when the model of the copying machine in which the IC card is set is different, or when the fixed magnification value of the copying machine is changed after data is registered in the IC card.

The present invention has been made in view of the above problems, and is intended to solve the above problems from the standpoint of preventing operator confusion and copying errors.

[Means and effects for solving the problems] The present invention provides: a first storage means for storing magnification value data associated with code data; a data management means for loading data from a second storage means for storing magnification value data; a magnification control means for setting a copy magnification according to the loaded magnification value data; a display means for displaying the set copy magnification; This is a variable magnification copying machine.

According to this configuration, when the operation mode is set based on the data in the second storage means, the magnification value is the magnification value registered in the second storage means, regardless of the code to which the magnification value is associated. is set. That is, the operator's desired magnification value is set.

Furthermore, since the set magnification value is displayed and the fixed magnification code is not displayed, operator confusion is also prevented.

In the following description, "r on edge" refers to a state change when the signal state changes from "off" to "r on."

(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, after setting the internal timer that defines the time for one routine (S3) and executing each process from S5 to S517, S1
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) Initial Routine (S5) This is a step for returning the operation mode of the copying machine to a "predetermined initial state" when predetermined initialization conditions such as input of the all clear key 95 are satisfied. In addition, "predetermined initial state"
Is the IC card 200 set in the copier?
It is selected differently depending on whether it is set or not.

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.

With any key input process as a condition (8101; Y
ES), starts the auto clear timer (S10
3) When the timer ends (S 105 ; YES), r
A predetermined initial state J (Sill or S 113) is set. Also when the all clear key 95 is pressed (S1
07; YES), the same is true.

In the above, the "predetermined initial state" is the mode defined by the data registered in the IC card (S109; YES) when the IC card is set (S109; YES).
113). However, regarding the magnification value, step 511
It is determined by the processing in step 5.

At step $115, a magnification check subroutine (see FIG. 11) is executed. As will be described later, this subroutine is a process for ignoring the magnification code data among the magnification data registered in the IC card and employing the magnification value data.

On the other hand, in the case where the IC card 200 is not set in the copying machine in step 5109 (S109; No), the "predetermined initial state tube" refers to step Sl (FIG. 4).
This is the initial state set in (Sill).

(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 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.
Then, the copy start flag is lowered and timer A and timer B are started (3207).

Also, turn on the paper feed roller clutch of the paper feed port corresponding to the selected paper size (S209.YES-5211
, 5213; YES-8215), starts feeding paper from the cassette, and sets the timer to end (S21).
7; YES), turn off the paper feed roller clutch (
5219).

5221 to 5231 are processing steps during a copy operation.

First, on the condition that the timer B ends (S221+Y
ES), generates a scanning signal to the optical system control unit 202 (
S 223). As a result, the optical system starts exposure scanning.

After that, a timing signal from the optical system is input (S
225; 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).

Further, on the condition that the timer C ends (S229;
YES), the charger, scan signal, and timing roller clutch are turned off (S231).

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 (S
233; YES), it is determined whether or not the set number of copies have all been completed (S235).

When it is determined that the set number of copies have been completed (32
35; YES), the developing motor and transfer charger are set to 0FFL and the timer D is started (S239) on the condition that the fixed position signal is input from the optical system control unit 202 (S239).
241).

On the other hand, if the set number of copies have not been completed in step 5235, a copy start flag is set (S237
), in preparation for the next copying operation for the same original.

5243 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 0FFI (S245), and starts an auto clear timer (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 FIG. 7 is a flowchart showing the details of S9.

5301-3323 are processes when inserting an IC card.

First, if the IC card is set in the card insertion section 70 of the copying machine (S301; YES), step 530
Proceeding to step 3, it is determined whether the copying machine is in a copying operation state. As a result, if it is in the copy state (S303; Y
ES), the copying state is canceled (S305), and the various operation modes at the time of the cancellation are saved in the memory within the copying machine body (S307). On the other hand, if the copying machine is not in the copying state (5303; No), the various operation modes set for the copying machine are saved in the memory within the copying machine body (S309).

Steps 3311 to 3315 are steps for setting the copying machine to various operation modes defined by data read from the IC card.

First, set the copying machine to the mode specified by the data registered in the IC card (number of copies, exposure amount, paper size data) (5311), and set the copy number display section 7.
2 displays the number of copies set with the above data (
S313). Furthermore, the aforementioned magnification check routine is executed (S315) to set the copy magnification of the value registered in the IC card. Further, the set magnification value is displayed on the magnification display section 73. Note that since the code data (code data corresponding to the magnification value data) is ignored, the display corresponding to the code data is not performed.

S31? -5323 are steps for setting the copying machine to an operation mode defined by the IC card data at the end of the copying operation.

That is, when the copy state ends (S317; YES)
sets the copying machine to the operating mode specified by the card data. Note that the copy magnification is processed by the magnification check subroutine described above (S319 to S53).
23). Nafuko's mode setting process is performed in steps 3311 to 5 above.
It is similar to 315.

Steps 8325 to 5327 are the processes performed when the IC card is pulled out from the card insertion section 70 of the copying machine.

That is, if the IC card is removed (S325; YE
S) sets the copying machine to the same initial state as in step St (FIG. 4) (S327).

In this case, r equal to j is selected as the magnification, and the display LED 103a corresponding to code 3 is lit.

(4) Number of sheets display routine FIG. 8 is a flowchart showing details of the above Stt.

First, in synchronization with the scan end timing of the optical system (S
401 ; YES), subtract °l' from the numerical value displayed on the sheet number display section 72 (5403), and further determine whether or not the sheet number display after the subtraction has become "0" (S40).
5).

If it is determined in step 5405 that the number of copies displayed is "0", the process advances to step 5407, where the original number of copies (the number of copies registered in the IC card) is displayed again on the number of copies display section 72, and the return is made. do.

On the other hand, in step 5401 or 5405, No.
If it is determined that this is the case, the process immediately returns to the main routine.

(5) Magnification Selection Routine FIG. 9 is a flowchart showing the details of step 513.

Steps 8501 to 5515 are processes for specifying a magnification code according to the selected fixed magnification key.

That is, when the on-edge of the fixed magnification key 100 is detected (5501; YES), "0" is substituted into the magnification code (S503).

Similarly, the fixed magnification key 101 is assigned a magnification code 1'', the fixed magnification key 102 is assigned a magnification code 2'', and the fixed magnification key 103 is assigned a magnification code 3''.
Each is substituted (S505 to 5515).

Next, in step 5517, the copying magnification stored in association with the selected magnification code is set in the copying machine. Note that the case where no magnification code is selected (when IC card data is loaded) will be described later. Also,
At step 5519, the fixed magnification corresponding to the selected magnification code is displayed and ED (any one of 100a to 103a) is lit.

Thereafter, the process returns to the main routine.

(6) Fixed magnification change routine FIG. 10 is a flowchart showing details of S15.

Steps 5601 to 8607 are processes corresponding to the input of the magnification change key.

That is, when the input of the magnification change key 104 is detected (3
601; YES), the process advances to step 5603 and determines the change mode flag.

As a result of the judgment, if the change mode flag is off (36
03; YES) sets the change mode flag, turns off the magnification value display section 73 (S605), and sets the input standby state for magnification value data.

On the other hand, if the change mode flag is set as a result of the determination in step 5603 (S603; No), the change mode flag is reset and the set magnification value is displayed on the magnification value display section 73 ( S607>.

Steps 3609 to 5615 are steps for storing new magnification values in association with fixed magnification keys.

That is, when the change mode flag is set (5609; YES), and when numerical data is input using the numeric keys 80 to 89 (S611; YES)
stores the above input numerical value as magnification value data in the memory area of the currently selected magnification code (
S613).

After that, reset the change mode flag (S615)
, return to the main routine.

(7) Magnification Check Routine FIG. 11 shows steps 5115 (FIG. 5) and 531
5 (FIG. 7) and 5323 (FIG. 7); FIG.

First, in step 51101, the fixed magnification code is deselected. As a result, the magnification value associated with the code in the copier will not be selected, and the 9th magnification value will not be selected.
(See Figure 551T).

Further, in step 31103, the copying magnification determined by the magnification value data registered in the IC card is set in the copying machine, and the magnification value is displayed on the magnification value display section 73.

Control of this copying machine is executed as described above.

As is clear from the above description, in the copying machine according to the present embodiment, when loading the magnification value data of the IC card and setting the copy magnification, the fixed magnification code is in a non-selected state. Also, the copy magnification registered in the card is set and displayed.

Therefore, it is possible to cope with the case where the magnification values associated with the same magnification code are different between the copying machine and the IC card.

On the other hand, since the magnification value data stored in the copying machine in association with the fixed magnification code is saved, the person who uses the copying machine next time is prevented from making a copy error.

Note that the above embodiment describes the case where data from an IC card is loaded, but the idea is similar to that of loading data from the memory (program memory) installed in the copier and specifying the data using the data. This also applies to the case where the operating modes for copying machines are set all at once.

〔Effect of the invention〕

As described above, the present invention provides data management that executes data loading from a first storage means for storing magnification value data associated with code data and a second storage means for storing magnification value data associated with code data. means, magnification control means for setting a copy magnification according to the loaded magnification value data;
The variable magnification copying machine has a display means for displaying a set copy magnification.

As described in the embodiment, according to the present invention, when the operation mode is set by the data in the second storage means, the magnification value is set in the second storage regardless of the code to which the magnification value is associated. The magnification value registered in the means is set. That is, even if the magnification values associated with the same code are different between the first memory and the second memory, the operator's desired magnification value is set.

Furthermore, since the set magnification value is displayed and the fixed magnification code is not displayed, operator confusion is also prevented.
