Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine having a trial copy function for visually confirming the copying condition of an image prior to normal copying.

[0002]

2. Description of the Related Art The test copy function is a function of making only one copy in order to visually confirm the creation state of an image on a recording sheet before making a plurality of copies. That is, even if a plurality of copies are set, the copying condition of the image is visually confirmed by not performing continuous copying immediately and copying only one sheet as a test and discharging it to a predetermined tray. If it is OK, continuous copying can be performed to make a copy without failure.

A conventional method is proposed, for example, in Japanese Patent Application Laid-Open No. 58-1162 (Japanese Patent Publication No. 2-2143), Japanese Utility Model Laid-Open No. 63-11641, and Japanese Patent Application Laid-Open No. 63-253969.

In the above, the printer has the print key and the trial copy key, and at the time of trial copying, after one copy, continuous copying is started after a lapse of a predetermined time. If the number of copy sets is "1", the trial copy is not performed.
When a plurality of originals are fed by the ADF (Automatic Original Feeder), the trial copy is performed only for the first original.
In the above, the method of interrupting at the first copy and continuing with the continue key is proposed. Further, in the above, a method has been proposed in which one copy is made by pressing only the print key, and continuous copying is made by pressing both the print key and the multi-copy confirmation key.

[0005]

By the way, in recent years, copiers have become multifunctional, and for example, the first sheet of a document stack is copied onto a special paper set as a cover in a predetermined tray by using an ADF. Special paper or plain paper, such as the cover copy mode for copying the second and subsequent originals onto plain paper set in another tray, and the chapter break mode for inserting a prespecified document as a slip sheet into chapters A method of selectively copying is known.

However, when trial copying is performed in the cover copy mode, the first sheet is copied onto special paper, and since the special paper is usually thick paper or color paper, the copying condition of the second and subsequent images of the original is determined. There is a problem in that it cannot be accurately confirmed. Also, in the chapter phrase cutting mode, the same problem occurs when the first sheet is specified as the slip sheet. Therefore, when the first sheet is specified as the slip sheet in the chapter phrase cutting mode, the plain paper tray is once selected and copied. Must be done.

Further, when copying a plurality of originals, even if the original image to be copied on the special paper is OK as a trial copy on the plain paper, it is actually copied on the thick paper or the color paper as the special paper. Then, it is often NG.

In view of the above conventional problems, it is an object of the present invention to provide a copying apparatus which can realize a trial copy function even in a mode in which a plurality of originals are selectively copied onto special paper or plain paper. To do.

[0009]

To achieve the above object, a first means is a paper selection copy mode for copying the first pages of a plurality of originals onto special paper, and a first page of a plurality of originals. In a copying apparatus having a test copy mode for interrupting copying of the second and subsequent pages, the first page of the document is a special paper when both the paper selection copy mode and the test copy mode are set. It is characterized in that it is provided with a control means for controlling so that copying is performed on both plain paper.

The second means is a paper selection copy mode for copying the first pages of a plurality of originals onto special paper, and a trial copy for copying the first pages of a plurality of originals and interrupting copying of the second and subsequent pages. A copying machine having a mode,
When both the paper selection copy mode and the trial copy mode are set, control means is provided to control so that the first page of the original is copied to plain paper regardless of the paper selection copy mode. And

A third means is a copy having a paper designated copy mode for copying designated pages of a plurality of originals onto special paper and a trial copy mode for copying one copy of a plurality of originals and interrupting copying of two or more copies. In the device, when both the paper selection copy mode and the trial copy mode are set, designated pages of a plurality of originals are copied to special paper, and undesignated pages are copied to plain paper. It is characterized in that it is provided with control means for controlling.

The fourth means further comprises density setting means for setting the density to be copied to the plain paper and the density to be copied to the special paper in the third means, and both the paper selection copy mode and the trial copy mode are provided. If is set,
The control means controls the plain paper and the special paper to be copied at the respective densities designated by the density setting means.

A fifth means is characterized in that, in the third or fourth means, the control means controls so that only one page of the original is copied onto plain paper.

A sixth means is a copy having a paper designated copy mode for copying designated pages of a plurality of originals onto special paper and a trial copy mode for copying one copy of a plurality of originals and interrupting copying of two or more copies. The apparatus is a density setting means capable of setting the density to be copied onto the special paper only when the paper selection copy mode is set, and a copy to the special paper with the density specified by the density setting means. And a control means for controlling.

[0015]

In the first means, the paper selection copy mode for copying the first pages of a plurality of originals onto special paper, and the trial copy for copying the first pages of a plurality of originals and interrupting the copying of the second and subsequent pages When both modes are set, the first page of the original is copied onto both special paper and plain paper, so the test copy function can be used even in the mode in which the first pages of multiple originals are copied onto special paper. Can be realized. Further, when the previous user changes only the paper without changing the settings of the special paper tray and the plain paper tray, it is not necessary to pull out the tray and check the paper type.

In the second means, a paper selection copy mode for copying the first pages of a plurality of originals onto special paper and a trial copy for copying the first pages of a plurality of originals and interrupting copying of the second and subsequent pages. When both modes are set, the first page of the original is copied to plain paper regardless of the paper selection copy mode.
The trial copy function can also be realized in a mode in which the first pages of a plurality of originals are copied onto special paper.

According to the third means, both a paper designated copy mode for copying designated pages of a plurality of originals onto special paper and a trial copy mode for copying one copy of a plurality of originals and interrupting copying of the second and subsequent copies. When set, the specified pages of the original are copied to special paper, and the pages that are not specified are copied to plain paper, so when multiple originals are selectively copied to special paper or plain paper. Also, the trial copy function can be realized.

In the fourth means, the plain paper and the special paper are copied at the respective densities designated by the density setting means, so that the respective densities actually copied to the plain paper and the special paper can be tried. .

In the fifth means, since only one page of the original is copied onto the plain paper, it is possible to prevent the plain paper from being wasted.

In the sixth means, the density to be copied onto the special paper can be set only when the paper selection copy mode is set, so that the operability can be improved even when there are many modes. .

Addresses and data are exchanged between the address decoder 288 and the like via the nonvolatile RAM 291 and the system reset unit 292.

Next, the cover mode will be described. In the cover mode, special paper such as thick paper or color paper is generally used as the cover paper. Therefore, even if the size is the same as that of plain paper, the type of paper is different, so the cover paper and plain paper are set in different paper feed trays in advance. This tray setting is set in a mode called a user tool, and one of the plurality of paper feed trays 112, 113, 114 is selectively set as a cover tray. At the time of copying in the cover mode, the first image of the document stack is copied onto the paper from the paper feed tray set as the cover tray, and the second and subsequent sheets are copied onto the paper from the plain paper tray. The last page of the original is copied to plain paper or cover paper depending on the setting of the front cover or both cover pages.

The cover mode is set by the cover selection key 263 or both cover selection keys 264 on the screen shown in FIG. In this embodiment, the first tray 112 is set in advance as a cover tray, and when the cover cover selection key 263 or both cover cover selection keys 264 is pressed, the first image is displayed as the first image.
It is copied onto the paper in the tray 112. Also, when the paper sizes of the first tray 112 and the third tray 114 are the same, the second and subsequent sheets are copied to the paper of the third tray 114.

In the chapter break mode, the originals of the page designated by the number of sheets and the like are copied onto the paper of the paper feed tray set as the interleaf tray, and the originals of other pages are copied onto the paper of the plain paper tray. The chapter break mode is set by the chapter break key 263 on the screen shown in FIG. 3, and when the chapter break key 263 is pressed, the screen is switched to the manuscript designation screen shown in FIG. Use the numeric keypad 207 to specify the page, then press the # key 268.
Confirm by. In addition, there are a maximum of 10 designated pages. In this embodiment, the second tray 1 is used as the interleaving paper tray.

Next, the trial copy process when one or both of the cover mode and the chapter break mode are selected will be described. First, when the cover mode is selected as described above, two paper feed trays are selected, and copying is performed under the conditions such as the set magnification and density and the number of copies. When the test copy start key 242 is not pressed and the start key 205 is pressed, the test copy is not performed and the copy is performed for the number of set sheets. When the sort mode is set as the discharge mode, the set number of sets are discharged to each bin of the sorter C.

On the other hand, the trial copy start key 24
When 2 is pressed, as shown in FIG.
ta is incremented by 1 (step S1), and if at least one of the front cover mode and both cover modes is set, the data Data is further incremented by 1 (steps S2 to S4). Next, when the chapter break mode is set, the data Data is further incremented by 1 (steps S5 and S6).

Next, when Data = 1, that is, when only the trial copy mode is set and neither the cover mode nor the chapter break mode is set, the original feeding of the first page is set as the copy sequence setting. And the plain paper tray and the proof tray 3 as the output tray.
Is selected (steps S7 → S8), the copy sequence is executed (step S9), and this test copy is completed.

On the other hand, if the cover mode is not set and the chapter break mode is set, step S10 is performed.
From step S11 to step S12,
The original feeding of the first page, the selection of the interleaf sheet tray, and the selection of the proof tray 3 as the ejection tray are performed as copy sequence settings, and the process proceeds to step S14. If the chapter break mode is not set but the cover mode is set, the process proceeds from step S10 to step S11 to step S13 to set the copy sequence settings for the first page document feed and the cover tray. And the proof tray 3 as the discharge tray are selected, and step S1
Go to 4.

In step S14, the above copy sequence is executed, and then the original of the first page is left as it is as the next copy sequence setting, and the plain paper tray and the proof tray 3 are selected as the discharge tray (step S15). ), The above copy sequence is executed (step S16), and this test copy is completed. Therefore, in the processing shown in steps S10 to S16, the original image of the first page is copied onto two sheets of slip sheet or cover sheet and plain sheet.

When Data = 3, that is, when both the cover mode and the chapter break mode are set, the process proceeds from step S10 to step S17, and the first page of the original is fed as the copy sequence setting. The cover tray is selected and the proof tray 3 is selected as the discharge tray, and the copy sequence is executed (step S
18). Then, as the next copy sequence setting, the original of the first page is left as it is, the interleaf sheet tray and the proof tray 3 are selected as the discharge tray (step S19), and the copy sequence is executed (step S20).

Next, as the next copy sequence setting, the original of the first page is left as it is, the plain paper tray and the proof tray 3 are selected as the discharge tray (step S21), and the copy sequence is executed (step S22). ), And ends this trial copy. Therefore, in the processing shown in steps S17 to S22, the original image of the first page is copied onto three sheets of the cover sheet, slip sheet, and plain sheet.

Therefore, when performing a trial copy, the first page of the original is printed on the special paper because the copy is made on each of the cover sheet, slip sheet, and plain sheet according to the setting state of the cover mode and the chapter break mode. The trial copy function can be realized even in the copy mode. After performing this test copy, the user visually confirms the copying condition and presses the start key 205 to copy the originals of the first or second page onto a sheet according to the setting state of the cover mode and the chapter break mode. To be done.

FIG. 7 shows the operation of a modification of the above embodiment.
When performing a test copy, if either cover mode or chapter break mode is set, the first page of the document is fed as copy sequence settings, the standard plain paper tray is selected, and the proof tray is used as the output tray. 3 is selected (steps S31 to S33 → S34), the copy sequence is executed (step S35), and this test copy is completed.

On the other hand, when neither the cover mode nor the chapter break mode is set, the original feeding of the first page as the copy sequence setting, the selection of the selected paper tray and the discharge tray are set. Select the proof tray 3 (steps S31 to S33 → S36),
The above copy sequence is executed (step S37), and this test copy is completed.

Next, a second embodiment will be described with reference to FIGS. 8 is a block diagram showing a circulation type automatic document feeder used in the second embodiment, FIG. 9 is an explanatory diagram showing a function selection screen of a display unit, FIG. 10 is a block diagram showing a developing device in detail, 11 is an explanatory diagram showing the developing bias voltage for each density notch, FIG. 12 is a flowchart for explaining the cover density setting process, FIG. 13 is a flowchart for explaining the cover density display control process shown in FIG. 12, and FIG. FIG. 15 is a flow chart for explaining the slip sheet density setting process, and FIG. 15 is a flow chart for explaining the trial copy process of the second embodiment.

The apparatus shown in FIG. 8 is of a system in which the document feed position and the document discharge position are the same. The lowermost document of the document stack placed downward on the document placement table 301 is attracted by the vacuum belt 302, and is fed to the left by the movement of the vacuum belt 302. Prior to this paper feeding, the document partitioning claw 315 for partitioning the document before and after the document feeding is once pulled in the upper left side of the drawing, and then returned to the original state to be set on the document stack. Here, when the final document is fed, the document partitioning claws 31 set on it are set.
The sheet 5 is dropped into the partition claw detection sensor 316 to detect the feeding of the final document.

The original fed in this state is sent to the intermediate conveying path 304 by the original feeding roller 303 and temporarily stopped. The stopped original is set on the contact glass 101 by the turn roller 305 and the original conveying belt 306 by the subsequent restart and read, and in the case of continuous paper feeding, the next original is set on the intermediate conveying path 304. .

The original on the contact glass 101 is not read after reading or in the trial copy mode described later, and the original conveying belt 306 and the original discharging roller 3 are not read.
08 and the switchback roller 310 cause the document discharge path 3
Sent to 09. The subsequent operation is different for a single-sided original and a double-sided original. In the case of a single-sided original, when the trailing edge of the original that has entered the original discharge path 309 is detected by the reversing sensor 311, the switchback roller 310 rotates in the reverse direction. The sheet is conveyed to the forward rotation discharge path 313 by the discharge switching claw 307 in the operating state, and is discharged downward by the document discharge rollers 314 onto the document stack on the document table 301.

On the other hand, in the case of a double-sided original, the switchback roller 310 does not reverse and the original discharge path 309.
The original that has entered the document advances as it is, and the original discharge roller 314
As a result, the document is discharged upward on the document stack on the document table 301. Therefore, in this state, when the paper is fed again, the back side is read, and the front side and the back side are restored by conveying the same path. In the case of this double-sided original, the paper whose front surface is copied is placed on the double-sided tray 124 shown in FIG. 1, and when the entire original bundle is copied, the back side of the original is copied from the first page.

On the screen shown in FIG. 9, a cover sheet density setting / display unit 271 and an interleaf sheet density setting / display unit 275 are added to the screen of the first embodiment shown in FIG. 3 and displayed. / Display units 271 and 275 are the concentration display unit 27, respectively.
2, 276, density up keys 273 and 277, and density down keys 274 and 278. In addition, the case of seven steps of the density adjustment key 243 is shown, and the density display unit 27
2,276 are also displayed at this stage.

Next, the operation for controlling the copy density will be described with reference to the developing device shown in FIG. The developing device 110 includes a toner cartridge 401 for supplying toner and a toner hopper 4 for supplying toner into the developing device 110.
02 and a toner replenishing brush 403, an elliptical plate 404 for stirring the replenished toner, first and second sleeves 405 and 406 for developing the latent image on the photoconductor 107 with the toner,
The sleeves 405 and 406 include a paddle wheel 407 that conveys the developer.

That is, the latent image on the photoconductor 107 is developed with toner, and the image density is determined by the amount of toner attached. In this case, the amount of toner adhered is determined by the sleeves 405, 40.
6 is controlled by the developing bias voltage applied to No. 6, and the developing bias voltage is determined by the state of the photoconductor 107, the density adjustment key 243, and the cover density setting / display unit 271.
11 and the sum of the voltages according to the set density of the interleaf paper density setting / display unit 275.

Next, the process of setting the cover density will be described with reference to FIG. The cover tray is set (step S
41), when the front cover key 263 is pressed, the process proceeds from step S42 to step S43 and below, while when both cover keys 264 are pressed, the process proceeds from step S42 to step S51 and below. If the front cover key 263 is pressed, it is determined whether or not the front cover mode is already set (step S43). If the cover cover mode has been set, the front cover mode setting flag is cleared (step S44), and the front cover mode is set. A cover unselected display is performed (step S45). That is, this key toggles.

On the other hand, when the front cover mode is not set, the front cover mode setting flag is set (step S46) and the front cover selection display is performed (step S4).
7). Next, both cover mode setting flags are cleared (step S48), and both cover non-selection display is performed (step S4).
9). Then, the cover density set by the density up key 273 or the density down key 274 is displayed (step S50).

When both cover keys 264 are pressed, it is judged whether or not both cover modes are already set (step S51). When both cover modes are set, both cover mode setting flags are cleared (step S52). ), Both covers are unselected and displayed (step S53). On the other hand, when the both cover mode is not set, the both cover mode setting flag is set (step S54), and both cover selection display is performed (step S55). Next, the front cover mode setting flag is cleared (step S56), the front cover unselected display is performed (step S57), and the cover density set by the density up key 273 or the density down key 274 is displayed (step S50).

In the display control shown in step S50,
As shown in FIG. 13, the cover mode setting flag is checked (steps S61 and S63), the cover density is displayed if it is set (ON) (step S64), and if it is cleared (OFF). The cover sheet density is erased (step S65).

Further, as shown in FIG. 14, chapter break key 2
If 65 is pressed, the slip sheet tray is set (step S71), then it is determined whether or not the chapter phrase cutting mode is already set (step S72), and if it is already set, chapter phrase cutting is performed. The mode setting flag is cleared (step S73), the chapter break is not selected and displayed (step S73).
74), and then the interleaf density set by the density up key 277 or the density down key 278 is displayed (step S75).

If the chapter phrase breaking mode is not set in step S72, the chapter phrase breaking mode setting flag is set (step S76), the chapter phrase breaking selection display is performed (step S77), and the process proceeds to step S75.
Also in step S75, similarly to the processing shown in FIG. 13, when the chapter phrase cutting mode flag is set, the cover sheet cover density is displayed, and when it is cleared, the cover sheet cover density is erased.

Next, the trial copy process will be described with reference to FIG. In FIG. 15, the number of originals is 10, and
An example is shown in which the first sheet is set as the cover sheet, the fifth sheet is set as the interleaf sheet, and the other originals are set as plain sheets. in this case,
Documents are sequentially fed one by one, and only the first, second, and fifth sheets are exposed and discharged. That is, other documents are discharged without being exposed even if they are fed.

When the first document is fed, the cover sheet is fed, the first document is exposed, and the electrostatic latent image is formed on the photoconductor 107. The upper latent image is developed with a developing bias according to the set density of the cover. Also, when the second original is fed, plain paper is fed and at the same time the developing bias is developed according to the normal bias (density set by the density adjustment key 24), and when the fifth original is fed, interleaving paper is fed. At the same time, it is developed with a developing bias according to the set density of the slip sheet. It should be noted that the difference in the paper feed timing of each sheet in FIG. 15 is due to the difference in the length of the transport path.

[0067]

As described above, according to the first aspect of the invention, the paper selection copy mode for copying the first pages of a plurality of originals onto special paper and the first page of a plurality of originals are copied. When both the trial copy mode that suspends the copying of the second and subsequent pages are set, the first page of the original is copied on both special paper and plain paper, so the first page of multiple originals is special. The trial copy function can also be realized in the paper copy mode. Further, when the previous user changes only the paper without changing the settings of the special paper tray and the plain paper tray, it is not necessary to pull out the tray and check the paper type.

According to the second aspect of the invention, the paper selection copy mode for copying the first pages of a plurality of originals onto special paper and the first page of a plurality of originals for copying the second and subsequent pages. If both the interrupted trial copy modes are set, the first page of the original is copied to plain paper regardless of the paper selection copy mode. The trial copy function can be realized even in the mode of copying onto special paper.

According to the third aspect of the present invention, a paper designated copy mode for copying designated pages of a plurality of originals onto special paper, and a trial copy for copying one copy of a plurality of originals and interrupting copying of the second and subsequent copies. When both modes are set, the specified pages of multiple originals are copied to special paper, and the unspecified pages are copied to plain paper. The copy function can be realized even when a plurality of copies are to be copied.

According to the fourth aspect of the invention, since the plain paper and the special paper are copied with the respective densities designated by the density setting means, the respective densities actually copied to the plain paper and the special paper are You can try.

According to the fifth aspect of the present invention, since only one page of the original is copied onto the plain paper, it is possible to prevent the plain paper from being wasted.

According to the sixth aspect of the present invention, since the density to be copied onto the special paper can be set only when the paper selection copy mode is set, the operability is improved even when a large number of modes are provided. Can be made.
