Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine which performs a copying operation under various copying conditions including a standard copying condition by operating a general-purpose copying key provided on an apparatus main body (operation unit), and a document setting device of an automatic document feeder. The present invention relates to a copying apparatus that performs a copying operation under standard copying conditions by operating a standard copying dedicated key provided near a position.

[0002]

2. Description of the Related Art In recent copying apparatuses, the number of copies, copying magnification, paper size, duplex mode, sorting mode, and the like can be freely set, and multi-functionalization is achieved. By the way, the number of copies is one, the copy magnification is
There are frequently used standard copying conditions, such as A4, single-sided / single-sided mode, in which the paper (transfer paper) size is used. Usually, the copying apparatus is often set to the standard copying conditions.

For this reason, the user often assumes that the copying condition is the standard copying condition and starts the copying operation without confirming the copying condition. In such a case, if the copy condition (other than the standard copy condition) set by the copying apparatus at the time of the previous execution of the copy operation is still set, the copy may be wasted. This useless copying may occur in large numbers as the speed of the copying apparatus increases. In particular, it is difficult to notice image differences such as differences in copy magnification, erasing of image frames, and binding margins.
Alternatively, there is an inconvenience that a notice is delayed when the user notices when actually using it.

Therefore, as shown in, for example, Japanese Patent Application Laid-Open No. 7-28361, a dedicated key (standard copy dedicated key) for starting the copying operation by resetting the copying condition to the standard copying condition is provided. There is a copying machine that has attempted to solve the problem. In this copying apparatus, a light-emitting display unit (light-emitting element such as an LED) is provided above a key dedicated to standard copying, and a document is set at a document setting position (document table) of an automatic document feeder (automatic document feeder). At times, the light-emitting display unit is caused to emit light to notify that the copying operation can be performed under the standard copying conditions.

[0005]

However, in such a conventional copying apparatus, even when the copying operation cannot be performed under the standard copying conditions, such as when no paper is set on the selected tray in the standard copying conditions, the copying operation cannot be performed. When a document is set at the document setting position of the automatic document feeder, the light-emitting indicator on the standard copy-only key emits light, so that the user can think that the copy operation using the standard copy-only key is possible. Sometimes.

When it is impossible to execute a copy operation under currently set copy conditions, a copy (print) disable display is normally displayed (for example, a red light-emitting display on a general-purpose copy key is displayed). Since the copy operation cannot be started under the above copy conditions (because the light is turned on or "Can be copied" is not displayed on the character display), the copy operation can be performed under the standard copy conditions (standard copy dedicated key) Even if
The user may misunderstand that the copying operation cannot be performed.

Further, when a certain user is making a copy under arbitrarily set copy conditions, another user may interrupt and make a copy under standard copy conditions (this is not limited to the interrupt mode copy). However, if the standard copy-only key is pressed by another user, the set copy condition is reset to the standard copy condition, and after the copy operation under the standard copy condition is completed, If the user makes a copy under the copy condition before the standard copy-only key is pressed, the copy condition must be set again.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to improve the operability of using a standard copy dedicated key in a copying apparatus having a standard copy dedicated key.

[0009]

In order to achieve the above object, the present invention provides a copy condition setting key for setting various copy conditions including a standard copy condition and a general-purpose key for starting a copy operation with various copy conditions.

It is a thing.

According to a second aspect of the present invention, in the copying apparatus of the first aspect, as shown in the functional block diagram of FIG. 1, the standard copying permission / inhibition judging means B judges that it is not possible to execute a copying operation under standard copying conditions. If it is determined that the paper is not set on the selected tray in the standard copying condition, the cause is determined by the selected tray. And other tray presence / absence determination means E for determining the presence / absence of another tray on which paper of the same size as the paper to be set is set. When a tray is determined to be present, a means for illuminating the light-emitting display unit on the standard copy-dedicated key is provided.

According to a third aspect of the present invention, in the copying apparatus of the second aspect, when the other tray presence / absence determination unit E determines that the other tray is present, the copy control unit A activates the standard copy dedicated key.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is an overall configuration diagram showing an example of a copying apparatus according to an embodiment of the present invention. FIG. 4 is a configuration diagram showing a circulating automatic document feeder (hereinafter referred to as "RDH") included in the copying apparatus. FIG. 5 also shows a normal automatic document feeder (hereinafter referred to as "AD
F ").

As shown in FIG. 3, the copying apparatus includes an RDH 11 for circulating a document and an ADF 1
2, and a finisher 3 is mounted on the side of the copying machine body 1.

The RDH 11 is a document table 21 shown in FIG.
Only the lowermost sheet of the original set with the image surface set downward is attracted to the vacuum belt 22 by the suction force, and the vacuum original is rotated to the left by the vacuum belt 22 that rotates counterclockwise. The document is conveyed to the feed port, but before the document is fed, the document separating claw 35 is once drawn into the upper left of the document, and then reappears, so that the document is set on the document bundle.

The document fed in this state is sent to an intermediate transport path 24 by a document feed roller 23, where it temporarily stops. The stopped document is set at a predetermined position on the contact glass 13 by the turn roller 25 and the document conveying belt 26 rotating clockwise by feeding after restart. In the case of continuous feeding, this feeding operation is performed continuously, and the next original is fed to the intermediate transport path 24.

The document set on the contact glass 13 is sent to a document discharge path 29 by a document conveying belt 26 and a document discharge roller 28 and discharged. In some cases it will be a different emission method. That is, in the case of a single-sided original, the original on the contact glass 13 is transported by the original transport belt 26 and guided to the original discharge path 29 by the discharge switching claw 27 at the switching position shown by the solid line in FIG. When the reversing sensor 14 detects the trailing end of the document once entering the document discharge path 29, the switchback roller 30 reversely rotates to reversely run.

At this time, since the discharge switching claw 27 has already been switched to the position indicated by the phantom line in FIG. The original is discharged onto the uppermost portion of the original bundle on the original mounting table 21 in the same original surface direction as the original. In the case of a two-sided original,
The document conveyed from the contact glass 13 by the document conveying belt 26 and guided to the document discharge path 29 proceeds to the reverse discharge path 32 as it is because there is no reverse rotation of the switchback roller 30.

Therefore, when the original is stacked on the original table 21 again, the top and bottom are reversed (front and back).
Then, in this state, when the original is fed again for copying on the second side, the back side of the second side is exposed on the contact glass 13 this time, and is again passed through the reversing discharge path 32. Is turned upside down, and is returned to the original (initial) front-back relationship again and stacked on the document table 21.

In this manner, the originals set on the original placing table 21 are sequentially fed from the lower side, and are circulated and returned to the original placing table 21 again for stacking. The detection of the final document is performed by dropping the document separating claw 35 set on the final document into the separating claw detection sensor 36 by feeding the final document from the document table 21.

ADF1 provided next to RDH11
2 has a configuration as shown in FIG.
The document bundle placed with the image surface facing down on
Only the lowermost document regulated by the separation blade 37 is fed by the call roller 40 and the separation roller 41, and is conveyed by the pull-out roller 42 to the turn roller 25 on the RDH 11 side.
6 is set at a predetermined position on the contact glass 13.

With the setting of the original, a copying process (copy process) to be described later is started, and copying is performed.
Subsequent operations may be the same as the operations of the RDH 11 described above. However, when discharging the original set on the contact glass 13 to the original discharge tray 44 shown in FIG. To the position shown by the imaginary line (upward switching), rotate the document conveying belt 26 clockwise, and turn on the ADF paper discharge roller 43 (rotation start).
To

However, if the original is a double-sided original, the original is discharged to the original discharge tray 44 after the back side copy is completed. The sheet is once guided to the document discharge path 29 by the discharge switching claw 27 at the switching position shown by the solid line in FIG.
When the switchback roller 30 rotates in the reverse direction, the vehicle runs backward.

At this time, since the discharge switching claw 27 has already been switched to the position indicated by the imaginary line in FIG. Since 38 is switched, it is sent to the intermediate transport path 24, turned upside down, and guided again onto the contact glass 13. The subsequent discharge is the same as in the case of a one-sided original.

The copying operation of the above-described copying apparatus equipped with the RDH 11 and the ADF 12 is performed by setting a necessary processing mode by an operation unit (described later) provided in the copying machine body 1 of FIG. It is started by pressing the standard copy-only key. When the key is pressed, a document is fed from the RDH 11 or the ADF 12 as described above, and is conveyed onto the contact glass 13. Then, the entire surface is irradiated by the flash lamp 52 there.

The power source 53 of the flash lamp 52 is
Charge is given prior to the flash, and light is emitted at a predetermined timing. The reflected light from the original exposes a belt-type photoconductor 7 via a first mirror 4, a through lens 5, and a second mirror 6. The photoreceptor 7 is uniformly charged by the charger 8, and an electrostatic latent image is formed on the surface by the exposure. An unnecessary portion of the electrostatic latent image on the photoreceptor 7 is removed by an eraser 9, developed by a developing unit 10, and sent to a transfer unit.

The developed document image is transferred to transfer paper by the transfer charger 17. The transfer paper is fed to the transport path 55 from one of the paper feed trays 18, 19, and 20 and the double-sided tray 45, and the transfer paper is sensitized by a registration roller 56 in synchronism with the original image on the photoreceptor 7. It is sent between the body 7 and the transfer charger 17. Then, the transfer paper on which the image has been transferred is separated from the photoconductor 7 by the separation charger 50 and sent to the fixing device 58 by the conveyor belt 57, where the image is fixed.

In this way, in this copying apparatus, the copying process is executed. In the copying process, in the duplex mode in which the image is copied on both sides of the transfer paper, the duplex switching claw 61 is switched to the duplex tray 45 side. Then, the transfer paper is sent to the double-sided tray 45 from the double-sided approach path 63, and is temporarily stacked in the double-sided tray 45.

In the single-sided mode in which an image is copied on only one side of the transfer sheet, the double-sided switching claw 61 is switched to the sheet discharging side, and is conveyed to the sheet discharging switching claw 62. The discharge switching claw 6
Reference numeral 2 functions to switch between discharging the discharged transfer paper to the main body tray 49 and discharging to the finisher (peripheral device) 3. After the transfer paper is separated, the photosensitive member 7 is neutralized by a neutralization charger 65, and a cleaning device 66 is provided.
As a result, the remaining toner on the surface is removed to prepare for the next copy.

When the transfer paper (copy paper) subjected to the copy processing is discharged to the finisher 3, when the selected copy mode (copy mode) is the one-sided mode, the paper is discharged from the first copy paper. Reversing unit 1
The sheet is turned over by 00 and discharged to the staple tray 200 or the shift tray 210. In the double-sided mode, since the sheet is ejected after the back side copying is performed, the sheet is ejected without being inverted.

The staple switching claw 211 switches between discharging the copy sheet from the reversing unit 100 to the staple tray 200 or discharging to the shift tray 210. The staple tray 200 is a tray for temporarily stacking sheets discharged to the shift tray 210 in order to staple a copy sheet bundle. When the final copy sheets are stacked on the staple tray 200, the copy sheet bundle is bound by the stapler 212 and then discharged to the shift tray 210 by the lift-up belt 213.

Alternatively, when it is not possible to execute a copy operation under standard copy conditions by pressing the standard copy dedicated key 48,
Alternatively, after executing the copy operation under the standard copy condition by pressing the standard copy dedicated key 48, the function as a means for returning the set copy condition from the standard copy condition to the copy condition before the standard copy dedicated key is pressed is performed. Alternatively, it functions as a means for prohibiting the input of the standard copy exclusive key 48 during the interruption mode.

In this copying apparatus, for example, as shown in FIG.
A standard copy exclusive key (print key) 48 according to the present invention is provided in the vicinity. This standard copy exclusive key 48
As shown in the enlarged view of FIG. 12, a light-emitting display unit (L) for displaying whether or not a copying operation can be performed under standard copying conditions is shown.
ED) 48a is embedded.

In this copying apparatus, when the copying operation can be performed under the standard copying conditions, the execution of the copying operation by the standard copying key 48 is permitted, and the light emitting display section 48a on the standard copying key 48 emits light. (Lit). When the standard copy exclusive key 48 is pressed, the copy operation is started under the standard copy conditions regardless of the set (set) copy conditions. At this time, the set copy conditions are reset to the standard copy conditions.

The standard copying conditions are not limited to the above, but the feeding tray is the third feeding tray 20, the density is automatic density, the magnification is the same, the number of copies (number of copies) is one, and the discharge destination is Is set on the main body tray 49.

For example, when there is no transfer paper in the first paper feed tray 18 but there is transfer paper in the third paper feed tray 20, the selected tray in the set copy condition is the first paper feed tray. If the rest of the paper tray 18 is the same as the standard copying condition, the copying operation cannot be executed under the set copying condition, but the copying operation can be executed under the standard copying condition. Therefore, the copying operation cannot be started with the general-purpose copy key (normal print key) 74, but can be started with the standard copy-dedicated key 48.

The shift tray 21 of the finisher 3
0 is full and cannot be ejected, but if the main body tray 49 can be ejected, it is set even if the selected ejection destination in the set copying conditions is the shift tray 210 and the others are the same as the standard copying conditions. Although the copying operation cannot be executed under the given copying condition, the copying operation can be executed under the standard copying condition. Therefore, the copying operation cannot be started with the general-purpose copy key 74, but the copying operation can be started with the standard copy-dedicated key 48.

Further, the stapler 21 of the finisher 3
In No. 2, the staples are gone, but if the main body tray 49 can be ejected, the stapler 212 is set even if ON / OFF of the stapler 212 in the set copy condition is ON and the others are the same as the standard copy condition. Although the copying operation cannot be executed under the given copying condition, the copying operation can be executed under the standard copying condition. Therefore, the copy operation cannot be started by the general-purpose copy key 74, but the standard copy-only key 4
At 8 the copying operation can be started.

Note that the standard copy exclusive key 48 is
2 is used to start the copying operation using
Of course, it is also possible to use it when starting a copying operation using the DH11. Here, RDH1
The difference between ADF 1 and ADF 12 depends on whether or not a copying operation is performed by circulating a document. The ADF 12 is suitable for copying an image of one document onto a plurality of transfer sheets because the document cannot be returned to the document mounting table. However, by not circulating the document through the RDH 11, it is possible to perform the same copying operation as when the ADF 12 is used.

FIG. 13 shows a first embodiment of this copying apparatus.
9 is a flowchart illustrating an example of a process corresponding to FIG. This routine is called and started by a main routine (not shown). First, at step 1, it is determined whether or not the copying operation can be performed under the standard copying condition (impossible). If there is no cause for failure, the standard copy exclusive key 48 shown in FIG.
The upper light emitting display unit 48a is turned on (light emission), and if it is impossible, the light emitting display unit 48a is turned off in step 2.

As described above, by turning on the light-emitting display section 48a on the standard copy-only key 48 only when the copy operation can be performed under the standard copy condition (standard copy-only key 48), the user can operate the standard copy only. It is possible to recognize whether or not the copying operation can be executed under the copying conditions, that is, whether or not the standard copying-specific key 48 can be used. Therefore, misunderstanding of the user is not caused, and operability can be improved.

FIG. 14 is a flowchart showing an example of the processing corresponding to the second and third aspects of the copying apparatus. This routine is also called by the main routine and started. First, at step 11, it is determined whether or not the copying operation can be performed under the standard copying conditions (impossible). If not, the light-emitting display section 48a on the standard copy-specific key 48 is turned on (emit light) in step 18.

If it is not possible to execute the copying operation under the standard copying conditions, the cause is determined in step 12 and
If the cause is only in the selected tray in the standard copying conditions (if no transfer paper is set in the selected tray), go to step 13; otherwise, go to step 17 Go forward respectively. Step 1
In 3, it is determined whether there is another paper feed tray on which transfer paper of the same size as the transfer paper to be set on the selected tray in the standard copy conditions is present. move on.

If there is another paper feed tray, the standard copy exclusive key 48 is depressed in step 14 (O
N) It is determined whether or not the button is pressed. If the button is not pressed, the light emitting display portion 48a on the standard copy dedicated key 48 is turned on in step 18; The copy operation is performed under the standard copy condition (excluding the selected tray) by changing to the paper feed tray.

Next, in step 16, a message "The paper feed tray has been changed" is displayed on the message display 81 of the display unit 80 of the operation unit 70 (the changed contents such as the name of the changed paper feed tray are displayed. In step 17, the light-emitting indicator 48a on the standard copy key 48 is turned off.

As described above, when the copying operation can be performed under the standard copying condition (standard copying key 48), the light emitting display 48a on the standard copying key 48 is turned on. Even if no paper is set in the selected tray, if there is another tray in which paper of the same size as the paper to be set in the selected tray is present, the light-emitting indicator 48a on the standard copy exclusive key 48 By illuminating, in addition to the same effect as the above-described processing according to claim 1, the user's hand can be eliminated, and the operation time can be saved, so that the work efficiency is improved.

If there is another paper feed tray, when the standard copy exclusive key 48 is pressed, the tray selected in the standard copy condition is changed to the other tray and a copy operation is executed under the standard copy condition. However, by displaying the above changes, the user is urged to confirm the change, and informed that the copying operation is different from the copying operation under the standard conditions desired by the user.
Misunderstanding to the user can be eliminated.

FIG. 15 is a flow chart showing an example of the processing corresponding to claims 4 and 5 in this copying apparatus. This routine is also called by the main routine and started. First, in step 21, it is determined whether or not the copying operation can be performed under the standard copying condition (impossible). If there is no), in step 28, the light-emitting indicator 48a on the standard copy-specific key 48 is turned on (emit light).

If it is not possible to execute the copying operation under the standard copying conditions, the cause is determined in step 22 and
If the cause is only at the selected discharge destination in the standard copying condition (when the selected discharge destination cannot be discharged), go to step 23.
If there is another destination other than the selected discharge destination in the standard copy conditions, the flow advances to step 27. In step 23, it is determined whether or not there is another discharge destination.
Proceed to.

If there is another discharge destination, it is determined in step 24 whether or not the standard copy dedicated key 48 has been pressed (ON). When the light-emitting display section 48a is turned on and pressed, the selected discharge destination in the standard copy conditions is changed to another discharge destination in step 25, and the copy operation is executed under the standard copy conditions (excluding the selected discharge destination). In step 26, a message "the discharge destination has been changed" is displayed on the message display 81 of the display unit 80 of the operation unit 70 (the changed contents such as the changed discharge destination name may be displayed). The light emitting display 48a on the dedicated key 48 is turned off.

As described above, when the copying operation can be performed under the standard copying condition (standard copying dedicated key 48), the light emitting display section 48a on the standard copying dedicated key 48 is turned on. Even if the selected discharge destination is not dischargeable, if there is another discharge destination, the light emission display section 48a on the standard copy-specific key 48 is turned on to provide the same effect as the above-described processing according to claim 1. This eliminates the need for the user to perform the operation and saves time and effort in operation, thereby improving work efficiency.

If there is another discharge destination, when the standard copy exclusive key 48 is pressed, the selected discharge destination in the standard copy conditions is changed to another discharge destination, and the copy operation is executed under the standard copy conditions. By displaying the contents of the change, the user is prompted to confirm the change, and is notified that the copying operation is different from the copying operation under the standard conditions desired by the user, so that misunderstanding to the user can be eliminated, and The user can immediately find the copy paper discharged to the changed discharge destination without hesitation.

FIGS. 16 and 17 are flow charts showing an example of the processing corresponding to claims 6 and 7 in this copying apparatus. These routines are also called and started by the main routine. In the routine of FIG. 16, first, at step 31, it is determined whether or not the standard copy-specific key 48 has been pressed (ON).

If the standard copy exclusive key 48 is depressed, it is determined in step 32 whether or not the interrupt mode (interrupt copy) is in progress. If the interrupt mode is in effect, the process is terminated (standard). If the input of the copy-only key 48 is prohibited, but is not in the interrupt mode, a flag (standard copy-only key flag) for performing a copy operation by pressing the standard copy-only key 48 is set to "1" in step 33 ( ON).

Next, at step 34, the currently set copy conditions are stored in a memory (eg, RAM 222).
After changing (resetting) the set copy condition to the standard copy condition in step 35, it is determined in step 36 whether or not the copy operation can be performed under the standard copy condition (impossible). If possible, the execution of the copying operation is started in step 37.

If it is not possible to execute the copying operation under the standard copying conditions (for example, if there is no transfer paper in the third paper feed tray 20 selected under the standard copying conditions), step 38 is performed.
After the standard copy key flag is reset to "0" (OFF) in step 39, the set copy condition is returned to the copy condition before the standard copy dedicated key 48 was pressed, that is, the copy condition stored in the memory in step 39. .

On the other hand, in the routine of FIG. 17, it is first determined at step 41 whether or not the copying operation has been completed, and when the copying operation has been completed, the standard copying-dedicated key flag is set to "1" at step 42. Judge whether or not
If it is set to "1" (since the copying operation started in step 37 is completed), the standard copying-dedicated key flag is reset to "0" in step 43, and then the set copying condition is changed to standard copying in step 44. The copy condition before the key 48 is pressed is returned.

As described above, when it is not possible to execute the copying operation under the standard copying condition by pressing the standard copying dedicated key 48, or after the copying operation under the standard copying condition by pressing the standard copying dedicated key 48, The following effects can be obtained by returning the set copy conditions from the standard copy conditions to the copy conditions before the copy / copy dedicated key 48 is pressed.

That is, when a user is making a copy under arbitrarily set copy conditions and another user interrupts and makes a copy under the standard copy conditions (except for the interrupt mode), the above-mentioned another copy is performed. After the copy operation is completed by the user pressing the standard copy dedicated key 48, but before the press (original)
Since the set copy condition is returned to the copy condition of the above, it is not necessary for the above-mentioned user to perform a key operation for resetting the copy condition when copying under the original copy condition. There is no need to worry about the copy conditions set for use.

Further, since the input of the standard copy-only key 48 is prohibited during the interrupt mode, the copying operation is not started by pressing the standard copy-only key 48 during the interrupt mode, so that the setting of the interrupt mode is released. After that, it is possible to prevent the user from starting the copying operation without confirming that the copying conditions at the time of setting the mode remain, thereby preventing the occurrence of erroneous copying. Further, it is not necessary to perform a key operation for resetting the copy conditions before the interrupt mode is set. Therefore, the operability in using the standard copy exclusive key 48 is improved.
