Abstract

PROBLEM TO BE SOLVED: To provide a copying device which can be provided with a charge processing device excellent in handleability as adjunct by controlling the preprocessing and the postprocessing of the image forming operation of a copying machine by referring to the remainder of a copying charge fed in a charge processing device. SOLUTION: A copying mode is set by slotting coins, and the image forming operation is started by turning on a printing key (P5). The copying charge is subtracted from the sum of fed money (P8). When copying equivalent to the set number of copies is finished and the remainder is equal to or under the copying charge for one copy (P9, P10 and P11), the cleaning control of a transfer drum is performed (P12). When copying is finished and the remainder is equal to or under the copying charge for one copy, a user slots the coins as much as the charge in the charge processing device and resets the copying mode even when the user continuously performs copying, so that the cleaning control of the transfer drum is finished during the above, and the user is not aware of waiting time. The preprocessing and the postprocessing of the image forming operation other than the cleaning control of the transfer drum are performed.

An image latent image formed on the photosensitive drum 115 by the laser light projected from the laser device 113 is
The image is developed by four color developing units 116 to 119 of cyan, magenta, yellow, and black which are sequentially selected.

The recording paper of a desired size fed from the paper feed cassettes 120 to 122 is temporarily stopped by the timing roller 123 and then stopped by the electrostatic attraction roller which is disposed opposite to the attraction roller 124. The toner is absorbed onto the transfer drum 126 by the jewel 125. The toner image formed on the photosensitive drum 115 is transferred to the recording paper of the transfer drum 126.

[Transfer Drum Cleaning Control] The transfer drum cleaning control will be described. The cleaning control of the transfer drum is executed for the purpose of removing toner and residual charges adhered to the transfer film on the transfer drum by repeatedly performing a copy operation. Since the recording paper is adsorbed and held on the transfer drum, the toner adhered to the transfer film adheres to the back surface of the recording paper and stains the recording paper.

The cleaning control of the transfer drum is performed after all the image forming operations are completed, and the next copy operation cannot be started during the cleaning control. If an attempt is made to start the next copy following the end of the first copy, the transfer drum cleaning control is being executed, so the user must wait until the transfer drum cleaning control ends.

The transfer film gradually becomes dirty due to the repetition of the copy operation, but it is not always necessary to clean the transfer film each time one copy operation is completed. Therefore, in the present invention, after the copy operation is completed, it is determined whether or not to execute the cleaning control of the transfer drum with reference to the remaining amount of the fee processing device. Specifically, when the remaining amount is less than one copy fee, the transfer drum cleaning control is executed. When the balance is less than one copy fee,
If the user intends to make a further copy, it is necessary to newly add a shortage fee, so that the transfer drum cleaning control should be executed during the waiting time until the additional charge is completed. Therefore, the user does not need to feel the waiting time for the transfer drum cleaning control.

FIG. 4 is an enlarged cross-sectional view showing the structure of the transfer drum 126 and its surroundings. The cleaning control of the transfer drum is performed after the normal image forming operation is completed and the recording paper is separated from the transfer drum 126, and before the drum is stopped.

First, the transfer film stretched on the surface of the transfer drum 126 is recharged by the electrostatic suction charger 125, the suction roller 124, and the suction back-up film 125a, and the charge-removal charger 130 and the separation charger. Jia 129
Thus, the toner on the transfer film from which the charge has been removed is recharged. Next, the feather brush unit 135 is operated to collect toner on the transfer film. Next, the charge remaining on the inside and outside of the transfer film is removed by the charge removing charger 130 to initialize the transfer film.

FIG. 5 is a timing chart for explaining the timing of the above-described transfer drum cleaning control. The transfer film is recharged by the electrostatic suction charger 125, the suction roller 124, and the suction back-up film 125a. After a lapse of a predetermined time, the feather brush unit 135 is operated to collect the toner, and after a lapse of the predetermined time, the charge removal charger 130 is operated to remove the residual charge of the transfer film.

FIG. 6 is a flowchart for explaining the cleaning control of the transfer drum performed based on the balance information of the fee processing device. First, the copier is set in an operable state after a charge is input to the charge processor (step P1).
A copy mode is set based on input information such as color copy or monochrome copy, recording paper size, number of copies, and the like (step P2).

The input amount (remaining amount) is confirmed, and it is determined whether or not the copy is acceptable (step P3). If the amount is insufficient, a shortage fee is displayed (step P4). If the copy is acceptable, wait for the start key to turn on (step P
5) If it is ON, an image forming operation is executed, the recording paper is discharged, and the copy fee is subtracted from the balance (steps P6 and P).
7, P8).

It is determined whether or not copying of the set number has been completed (step P9), and if not completed, it is determined whether or not the next copy is possible from the remaining amount (step P10), and copying is possible. In the case of, the process returns to step P6, and in the case where copying is not possible, the process proceeds to step P12 described below.

If the copy is completed in the judgment in step P9, the remaining amount is checked to determine whether or not the remaining amount is sufficient for one or more copies (step P11). If the copy is possible, the rotation of the transfer drum is performed. Is stopped (step P13). If copying is not possible in step P11, cleaning control of the transfer drum is executed (step P12), and the routine goes to step P13.

As described above, since the copy is completed, the balance is confirmed (step P14). If there is a balance, it is determined whether or not the return button (see FIG. 1) is pressed (step P1).
5) If the return button is pressed, the balance is returned (step P16), and the process ends. If the remaining amount is zero in the determination in step P14, the process is also terminated. If the return button is not pressed in step P15, the process returns to step P2 to respond to the next copy request.

[Fixing Temperature Adjustment Control] The fixing temperature adjustment control will be described. Normally, a copying machine has a fixing temperature adjustment mode called a preheat mode for saving power consumption of the fixing heater during standby. In this mode, the set temperature of the fixing roller at the time of standby is controlled to be lower than the set temperature at the time of the operation of the fixing roller to save the power consumption of the heater.

In a conventional copying machine, as a method for entering the pre-heat mode, a method using a switch on the operation panel or a method for entering when no operation is performed for a predetermined time after the copy operation is completed, are adopted. Also, the release of the preheat mode is generally released when it is determined that the user has operated any of the switches on the operation panel. Even if the preheat mode is released, it takes a certain period of time to raise the temperature of the fixing roller to the operating temperature, during which the copying operation cannot be performed and the user must wait. Never

In the present invention, the timing of entering the pre-heat mode and the timing of canceling the pre-heat mode are determined with reference to the remaining amount of the fee processing device. Specifically, when the set copy mode is completed and the remaining amount of the fee processing device is determined to be zero, the system enters the pre-heat mode. This time is an appropriate time to enter the pre-heat mode because it is considered that the copying operation of the user has been completed.

The release of the pre-heat mode is performed when it is determined that a charge is to be input to the charge processing device.
Was released. Normally, the user sets the copy mode by operating the operation panel of the copying machine after charging the fee. During this time, the user can raise the temperature of the fixing roller to the operating temperature. Since it is possible, the user can start copying without feeling a waiting time.

FIG. 7 is a flow chart for explaining the fixing temperature adjustment control executed based on the balance information of the fee processing device.
It is. First, the copier is set to an operable state after the charge is input to the charge processing device (step P21), and the preheat mode is released (step P22). Color
The copy mode is set based on input information such as copy or monochrome copy, recording paper size, and number of copies (step P23).

After confirming the input amount (remaining amount), it is determined whether or not the copy is acceptable (step P24). If the amount is insufficient, the shortage fee is displayed (step P25). Copy
If it is acceptable, wait for the start key to be turned on (step P26). If the start key is turned on, the image forming operation is executed, the recording paper is discharged, and the copy fee is subtracted from the balance (step P26).
27, P28, P29).

It is determined whether or not the copy of the set number has been completed (step P30). If the copy has not been completed, it is determined whether or not the next copy is possible from the remaining amount (step P31).
If copying is possible, the process returns to step P27. If copying is not possible, the process proceeds to step P33 described below.

If the copy is completed in step P30, the remaining amount is checked to determine whether the remaining amount is sufficient for one or more copies (step P32). If the copy is possible, the rotation of the transfer drum is performed. Is stopped (step P34). If copying is not possible in the determination of step P32, cleaning control of the transfer drum is executed (step P33), and the routine goes to step P34.

As described above, since the copy has been completed, the balance is confirmed (step P35). If there is the balance, it is determined whether or not the return button has been pressed (step P36). If the return button has been pressed, Return the balance (Step P37)
The preheat mode is set (step P38), and the process ends. If the remaining amount is zero in the judgment in step P35, the process shifts to step P38, the pre-heat mode is set, and the process ends. If the return button is not pressed in the judgment in step P36, the process returns to step P23 in order to respond to the next copy request.

In the fixing temperature adjustment control described above, the transfer drum cleaning control is also performed in steps P31 to P33. However, when the control is performed in another control, it can be omitted in the operation of the fixing temperature adjustment control. Needless to say.

[Charge Charge Wire Cleaning Control] Charge charge wire cleaning control will be described. The cleaning control of the charged charge wire is performed by repeatedly performing the copy operation so that the scattered toner adheres to the charged charge wire and becomes dirty, and the fogging is generated on the formed image due to the reduced charging ability. It is executed for the purpose of preventing.

This control must be performed when the output to the charging charger is turned off and all the driving systems such as the photosensitive drums are stopped. In a conventional copying machine, when a copy of a predetermined cumulative number or more is performed and the operation of the copying machine is stopped, the copying is automatically executed. During the cleaning of the charge wire, the copying operation cannot be started.

Here, the configuration of the charging charge wire will be described. FIG. 8 is a perspective view showing the configuration of the charging charge wire. The charging charge wire 83 is stretched by a suitable means on a frame 87 whose outline is indicated by a chain line. A cleaner 82 penetrates through the charging charger wire 83 and is disposed so as to be movable in the longitudinal direction of the wire.
2 is a cleaner wire 8 driven by a cleaning motor 81.
6 to clean the charged charge wire 83.
Movement and stop of the cleaner 82 are performed based on the position signal of the cleaner 82 detected by the cleaner fixed position sensor 84 and the cleaner return position sensor 85. The suspension is controlled.

According to the present invention, the control of the charging and charging wire cleaning is determined with reference to the balance information of the charge processing device. More specifically, when the set copy mode is completed and the remaining amount of the fee processing device is determined to be zero, the charging charge wire cleaning control is executed. Since it is considered that the copying operation by the user has been completed, this time is an appropriate time for executing the charging charge wire cleaning control. Also,
Even if the user puts the fee into the fee processing device again,
Since the cleaning of the charged charge wire is completed within the time until the copy mode is set by operating the operation panel of the copying machine, the user can start copying without feeling a waiting time. it can.

FIG. 9 is a flow chart for explaining the cleaning control of the charged charge wire executed based on the balance information of the fee processing device. First, the copier is set in an operable state after a charge is input to the charge processor (step P41), and based on input information such as color copy or monochrome copy, recording paper size, and the number of copies. The copy mode is set (step P42).

After confirming the input amount (remaining amount), it is determined whether or not the copy is allowable (step P43). If the amount is insufficient, the shortage fee is displayed (step P44). Copy
If it is acceptable, wait for the start key to be turned on (step P45). If it is on, execute the image forming operation, discharge the recording paper, and subtract the copy fee from the balance (step P45).
46, P47, P48).

It is determined whether or not the copy of the set number has been completed (step P49). If not, it is determined whether or not the next copy is possible from the remaining amount (step P50).
If copying is possible, the process returns to step P46. If copying is not possible, the process proceeds to step P52 described below.

If the copy is completed in step P49, the remaining amount is checked to determine whether or not it is possible to copy one or more copies (step P51). If the copy is possible, the rotation of the transfer drum is performed. Is stopped (step P53). If copying is not possible in the judgment of step P51, cleaning control of the transfer drum is executed (step P52), and the routine goes to step P53.

As described above, since the copy has been completed, the balance is confirmed (step P54), and if there is a balance, it is determined whether or not the return button has been pressed (step P55). If the return button has been pressed, Return the balance (Step P56)
Execute the cleaning process of the charged charge wire (Step P
57), and the process ends. If the remaining amount is zero in the judgment in step P54, the process proceeds to step P57, in which the charging charging wire cleaning process is executed, and the process ends. If the return button is not pressed in step P55, the process returns to step P42 in order to respond to the next copy request.

In the above description, the charging charge wire cleaning control is executed when the set copy mode is completed and the remaining amount of the fee processing device is determined to be zero, but prior to the copy. When it is determined that the user has charged the fee processing device, the charging charge wire cleaning control may be immediately executed. Also in this case, within the time until the copy mode is set by operating the operation panel of the copier,
Since the cleaning of the charged charge wire is completed, the user can start copying without feeling a waiting time.

In the cleaning control of the charged charger wire described above, the cleaning control of the transfer drum is also performed in steps P50 to P52. However, when the control is performed in other control, the cleaning control of the charged charger wire is performed. Needless to say, the operation can be omitted.

[Control of Stirring of Developing Unit] Next, control of stirring of the developing unit will be described. Use toner and carrier 2
In the developing method using the component developer, the charge amount of the toner greatly affects the developing performance, and the charge amount of the toner is stabilized by sufficiently stirring the toner and the carrier in the developing device. Can be maintained.

However, when the developing unit is not driven for a long time and the toner and the carrier are not sufficiently stirred, the charge amount of the toner changes, and in many cases, the charge amount of the toner decreases, and the developing characteristics increase. It will pass. In such a case, the toner cannot be sufficiently charged only by stirring the toner and the carrier by driving the developing device during image formation, and the toner is not sufficiently charged and is subjected to development processing, and the image is fogged. Or uneven density may occur.

It takes a considerable amount of time to stir the developing device at the start of the copy operation to secure the required amount of charge, so that the copy operation cannot be started quickly, so that the copy is discharged. It takes a long time for the copying, and the usability of the copying machine is not good.

Therefore, in the present invention, the stirring control of the developing device is executed by referring to the balance information of the fee processing device. Specifically, when the fee is charged to the fee processing device, the stirring control of the developing device is executed. After the user enters the charge, the toner and the carrier in the developing device are sufficiently agitated within the time until the copy mode is set by operating the operation panel of the copying machine, and the necessary charge amount is obtained. The user can start copying without feeling a waiting time.

FIG. 10 is a flowchart for explaining the stirring control of the developing unit executed based on the balance information of the fee processing device. First, the copier is set in an operable state after a charge is input to the charge processor (step P61).
Stirring of the developing device is started (step P62).

The copy mode is determined based on input information such as color copy or monochrome copy, recording paper size, and the number of copies.
It is determined whether the setting of the code has been completed (step P63). If the setting has not been completed, it is determined whether a predetermined time has elapsed since the start of the stirring of the developing device (step P64). Step P63
If the setting of the copy mode is completed in the determination of step P64, and if the predetermined time has elapsed in the determination of step P64, the process proceeds to step P65, and if not, the process returns to step P63.

The stirring of the developing device is stopped (step P6).
5) Check the input amount (remaining amount) and determine whether the copy is acceptable (step P66). If the amount is insufficient, the shortage fee is displayed (step P67). If the copy is acceptable, wait for the start key to turn on (step P6).
8) If it is ON, the image forming operation is executed, the recording paper is discharged, and the copy fee is subtracted from the balance (step P69,
P70, P71).

It is determined whether or not the copy of the set number has been completed (step P72). If the copy has not been completed, it is determined whether or not the next copy is possible from the remaining amount (step P73).
If copying is possible, the process returns to step P69. If copying is not possible, the process proceeds to step P75 described below.

If the copy is completed in the determination in step P72, the remaining amount is checked to determine whether or not the remaining amount allows one or more copies (step P74). If the copy is possible, the rotation of the transfer drum is performed. Is stopped (step P76). If copying is not possible in the determination of step P74, cleaning control of the transfer drum is executed (step P75), and the routine goes to step P76.

As described above, since the copy has been completed, the balance is confirmed (step P77). If there is the balance, it is determined whether or not the return button has been pressed (step P78). If the return button has been pressed, Return the balance (Step P79)
The process ends. If the remaining amount is zero in the judgment in step P77, the process is also terminated. If the return button is not pressed in the determination in step P78, the process returns to step P63 to respond to the next copy request.

In the stirring control of the developing device described above, the cleaning control of the transfer drum is also performed in steps P73 to P75. However, if the control is performed in another control, it can be omitted in the stirring control of the developing device. Needless to say.

[Pre-Rotation Control of Photosensitive Drum] Next, the pre-rotation control of the photosensitive drum will be described. The photosensitive drum is charged by a charging charger while the photosensitive drum is rotating. After a certain time has elapsed after the photosensitive drum is stopped, the photosensitive drum is rotated again to perform charging. In order to ensure a sufficient charging potential in this case, it is necessary to rotate the photosensitive drum several times (pre-rotation of the photosensitive drum) while the charging charger is operated. This is because, if an image is formed without securing a charging potential required for the photoreceptor drum, fog may occur in the image or density unevenness may occur.

If the photosensitive drum is rotated several times at the start of the copying operation to secure a sufficient charging potential, it takes a long time until the first image is formed. Is not good.

Therefore, in the present invention, the pre-rotation control of the photosensitive drum is executed by referring to the balance information in the fee processing device. Specifically, when a fee is charged to the fee processing device, the photosensitive drum is rotated several times while the charging charger is operated. Within the time from when the user enters the charge to when the copy mode is set by operating the operation panel of the copying machine, the pre-rotation control of the photosensitive drum is completed and a sufficient charging potential can be secured. Therefore, the user can start copying without feeling the waiting time.

FIG. 11 is a flowchart for explaining the pre-rotation control of the photosensitive drum performed based on the balance information of the fee processing device. First, the copier is set in an operable state after a charge is input to the charge processor (step P).
81), the pre-rotation of the photosensitive drum is started (step P)
82).

The copy mode is determined based on input information such as color copy or monochrome copy, recording paper size, and the number of copies.
It is determined whether the setting of the mode has been completed (Step P83). If the setting has not been completed, it is determined whether a predetermined time has elapsed since the start of the pre-rotation of the photosensitive drum (Step P84). When the setting of the copy mode is completed in the judgment of step P83,
If the predetermined time has elapsed in the determination at step P84, the process proceeds to step P85, and if not, the process returns to step P83.

The pre-rotation of the photosensitive drum is stopped (step P85), and the amount of money (the remaining amount) is confirmed to determine whether the copy is acceptable (step P86). If the amount is insufficient, the shortage is displayed. (Step P87). If the copy is acceptable, wait for the start key to turn on (step P
88) If it is on, an image forming operation is executed, the recording paper is discharged, and the copy fee is subtracted from the balance (step P89,
P90, P91).

It is determined whether or not the copy of the set number has been completed (step P92). If not completed, it is determined whether or not the next copy is possible from the remaining amount (step P93).
If copying is possible, the process returns to step P89. If copying is not possible, the process proceeds to step P95 described below.

If the copy is completed in the determination in step P92, the balance is checked to determine whether or not it is possible to copy one or more copies (step P94). If the copy is possible, the rotation of the transfer drum is performed. Is stopped (step P96). If it is determined in Step P94 that copying is not possible, cleaning control of the transfer drum is executed (Step P95), and the routine goes to Step P96.

As described above, since the copy has been completed, the balance is confirmed (step P97). If there is a balance, it is determined whether or not the return button has been pressed (step P98). If the return button has been pressed, Return the balance (Step P99)
The process ends. If the remaining amount is zero in the determination in step P97, the process is also terminated. If the return button is not pressed in the judgment in step P98, the process returns to step P83 in order to respond to the next copy request.

In the above-described pre-rotation control of the photosensitive drum, the cleaning control of the transfer drum is also performed in steps P93 to P95. Needless to say, can be omitted.

Although the embodiment of the present invention described above is an example in which the present invention is applied to a full-color copying machine, it goes without saying that the present invention can be applied not only to a full-color copying machine but also to a monochrome copying machine. .

In the embodiment of the present invention described above, a charging charger is used as the charging means, but a charging film may be used as the charging means. Further, in the embodiment of the present invention, the transfer drum is used as the transfer unit. However, a transfer belt can be used as the transfer unit.
