Description

The present invention relates to a printing apparatus such as a digital copying machine, a printing method, and a program .

  In recent years, digital copying machines have been developed and are widely used.

  A digital copying machine reads an image with a CCD, converts it into a digital signal, performs various processing on it, converts it into a laser signal, and records it on a recording medium by electrophotographic technology.

  In addition, an image forming apparatus has been developed in which the image signal is stored once in an image memory such as a hard disk and then read out. 0 According to this, image formation can be repeated multiple times by reading an image once from a scanner. This is effective for realizing functions such as electronic sorting.

Furthermore, by providing this image memory, a trial printing function has been devised in which only one copy is formed and the user confirms the finish and then continues image formation or changes the setting mode to form an image. Yes. For example, Patent Document 1 discloses a method of executing trial printing in units of copies.

Japanese Patent Laid-Open No. 10-119365

  However, in the trial printing function, when the final trial printing is finished and the final image is printed, the number of copies to be printed is not considered based on the user's intention.

  For example, if the user prints one copy of the test print and then prints the remaining prints as a good print, the test copy is considered to be a regular print and the remaining prints are tested from the set number. It should be printed only by subtracting one copy.

  Further, if any mode change is made after the trial printing, it can be determined that the trial printing is an image formation that is not desired by the user, and therefore it is necessary to form an image for the number of images initially set during the continuous printing.

  However, since there has been no control of the number at the time of trial printing so far, there has been a problem that the user has to change the number one by one according to the situation.

The present invention has been made in view of the above-described circumstances, and can determine whether or not a mode has been changed in an interrupted state in which one copy of printing has been completed by trial printing, and can automatically change the number accordingly. An object of the present invention is to provide a printing apparatus, a printing method, and a program .

  This invention can solve the said subject by providing the following structure.

(1) Printing means, setting means for setting printing conditions, input means for inputting image data, first test printing according to image data input by the input means and printing conditions set by the setting means And a first control unit that controls the printing unit to execute, and after the printing unit executes the first test printing, a change instruction for changing the printing condition set by the setting unit is received. First receiving means, second receiving means for receiving an execution instruction for executing second test printing after the printing means has executed the first test printing, and the second receiving means When the execution instruction is received, the marking is performed so that the second test printing is executed in accordance with the image data input by the input unit and the printing condition changed according to the change instruction. And a second control means for controlling the means, the second reception unit receives the execution instruction through the predetermined display element displayed on the display unit, the printing unit is the first trial After executing printing, before the first receiving unit receives the change instruction , the first receiving unit does not display the predetermined display element so that the execution instruction can be received. After receiving a change instruction, the printing apparatus displays the predetermined display element so as to receive the execution instruction .
(2) A printing step, a setting step for setting printing conditions, an input step for inputting image data, first test printing according to the image data input in the input step and the printing conditions set in the setting step A first control step for controlling the printing step so as to execute, and a change instruction for changing the printing condition set in the setting step after the printing step has executed the first test printing. A first accepting step; a second accepting step for accepting an execution instruction for executing a second test print after the print step performs the first test print; and the second accepting step. When the execution instruction is accepted, it is changed according to the image data input in the input step and the change instruction. And a second control step of controlling the printing step so as to perform the second test print according to the printing conditions, the second receiving step, the via predetermined display element displayed on the display unit receiving an instruction to execute, after the said printing step executes the first test print, the before the first receiving step receives the change instruction, the predetermined display to be accepted the execution instruction An element is not displayed, and after the first receiving step receives the change instruction, the predetermined display element is displayed so that the execution instruction can be received .
(3) A program for causing a computer to execute the printing method described in (2) above .

  In the present invention, in view of the above-described situation, whether or not there is a mode change is determined in a suspended state in which printing of one copy has been completed by trial printing, and the number of copies is automatically changed accordingly.

  In other words, when the number of places is changed in the above-mentioned interruption state in trial printing, the remaining prints are printed for the number of places in the cascade print after the release of trial printing immediately after that, and the mode other than the number of places is changed. If there is no change in the mode, the remaining number is printed based on the number of digits that is obtained by subtracting 1 from the set number. While printing is performed and only one copy is always printed while the test print is set, the set number is kept as it is, so only the number of copies desired by the user can be printed. I think that the result can be provided without changing the numerical setting, and the effect is great.

  Hereinafter, description will be given with reference to the drawings.

  FIG. 1 is a cross-sectional view mainly showing the configuration of the reader unit 1 and the printer unit 2. The configuration and operation will be described.

  Documents stacked on the document feeder 101 are sequentially conveyed onto the document table glass surface 102 one by one. When the document is conveyed to a predetermined position on the platen glass surface 102, the lamp 103 of the scanner unit is turned on, and the scanner unit 104 moves to irradiate the document. Reflected light from the document is input to a CCD image sensor unit 109 (hereinafter referred to as CCD) via mirrors 105, 106, 107 and a lens 108.

  FIG. 2 is a circuit block diagram showing a signal processing configuration of the reader unit 1, and the configuration and operation will be described below.

  In FIG. 2, the reflected light of the original irradiated to the CCD 109 is photoelectrically converted and converted into electrical signals of red, green, and blue (R, G, B) colors. Color information from the CCD 109 is amplified in accordance with the input signal level of the A / D converter 111 by the next amplifiers 110R, 110G, and 110B. The output signal from the A / D converter 111 is input to the shading circuit 112, where the light distribution unevenness of the lamp 103 and the sensitivity unevenness of the CCD 109 are corrected. A signal from the shading circuit 112 is input to the Y signal generation / color detection circuit 113 and the external I / F switching circuit.

The Y signal generation / color detection circuit 113 calculates the signal from the shading circuit 112 by the following formula to obtain the Y signal.
Y = 0.3R + 0.6G + 0.1B
Furthermore, a color detection circuit that separates the R, G, and B signals into seven colors and outputs a signal for each color is provided. An output signal from the Y signal generation / color detection circuit 113 is input to the scaling / repeat circuit 114. Depending on the scanning speed of the scanner unit 104, scaling in the sub-scanning direction is performed, and scaling in the main scanning direction is performed by the scaling / repeat circuit 114. A plurality of identical images can be output by the scaling / repeat circuit 114. The contour / edge emphasis circuit 115 obtains edge emphasis and contour information by emphasizing the high frequency component of the signal from the scaling / repeat circuit 114. The signal from the contour / edge enhancement circuit 115 is input to the marker area determination / contour generation circuit 116 and the patterning / thickening / masking / trimming circuit 117.

  A marker area determination / contour generation circuit 116 reads a portion of a document written with a marker pen of a specified color, generates marker contour information, and a next patterning / weighting / masking / trimming circuit 117 Thicken, mask or trim from contour information. Further, patterning is performed by the color detection signal from the Y signal generation / color detection circuit 113.

  When the output signal from the patterning / thickening / masking / trimming circuit 117 is output to the printer unit 2, it is selected by the image data selector circuit 118 described later, input to the laser driver 119, and the processed signal is converted to the laser. It converts into the signal for driving. The output signal of the laser driver 119 is input to the printer unit 2 and image formation is performed as a visible image.

<Description of Image Memory 120>
In FIG. 2, an image memory 120 stores and reads out the image data sent from the image data selector circuit 118 at a designated position in the image memory 120 according to an instruction from the CPU 122 by a method described later, rotates the image data, It has the function of combining above.

  The CPU 122 controls the reader unit 1, and includes a ROM 124 that stores a control program, an error processing program, and the like, a RAM 125 that is used for a work area of various programs, and various timer control units. The operation unit 123 includes various key groups for instructing image operations such as image editing contents and the number of copies for image processing of the reader unit 1, a display unit for displaying the contents at the time of operation, and the like.

  FIG. 3 shows details of the operation unit 123 of this embodiment. In the operation unit 123, various keys and a liquid crystal display unit 301 configured by a dot matrix including a liquid crystal display device are arranged.

  The liquid crystal display unit 301 displays the state of the apparatus, the number of copies, the magnification, the selected paper, and various operation screens, and is operated by a control key.

  A start key 303 is a key for starting copying, and a return key (reset key) 304 is a key for returning the setting mode to the standard state. A key group 305 is a numeric keypad from 0 to 9 for inputting the number of copies, zoom magnification, and the like, and a clear key for clearing the input. The density key 306 is a key for increasing / decreasing the density, and the density adjusted thereby is displayed on the display unit 307. A key 308 is a key for turning on / off the automatic density adjustment function and a display portion thereof, and a key 309 is a key for selecting a paper feed stage and automatic paper selection, and this selection state is displayed on the liquid crystal display portion 301. Is done. A key 311 is a key for setting an equal magnification and a standard reduction / enlargement. A key 310 is a key for setting the auto scaling mode, and this selection state is also displayed on the liquid crystal display unit 301.

  An image storing method and a reading method will be described with reference to FIGS.

  (1) of FIG. 4 shows one storage capacity of the image memory. In this embodiment, A3 size storage is possible, and it is composed of vertical 4661 × horizontal 6596 bits. As shown in FIG. 5, this storage area is configured to store 100 images as one image layout area and an image storage area. Next, FIG. 4B shows an example in which a document image is stored in an image memory. (2) Documents placed as shown in a are sequentially read in the direction of the arrow as shown in the figure. First, when the first line is read, as shown in (2) b, (0, 0) When the address is designated as the start position for counting up in the X direction and counting up in the Y direction, and the first line is read first, the counter in the Y direction is sequentially written in the (0,4661) direction. Next, when the second line is read, the counter in the X direction is incremented and written sequentially from the (1, 0) address to the (1, 4661) address direction. Next, when the third line is read, the counter in the X direction is incremented and written from the (2, 0) address to the (2, 4661) address. In this manner, reading and writing are repeated, and writing is performed up to (3297, 4661).

  Next, the process of reading the image data written in the memory using (2) will be described using (3) and (4). In the data stored in (3), as shown in (3) a, first, in the first line, the (3271, 0) address is set to the start position, the X counter is counted down in order, and the Y direction counter is increased. It is specified and read while sequentially decreasing the X counter in the (0, 0) direction. Next, the Y counter is incremented, and the second line is read out, reading from the (3297, 1) address in the direction of (0, 1), and sequentially reading in this way to obtain the image of (3) b. I can do it.

  In (4), as shown in (4) b, for the stored data, first, on the first line, the address of (0, 0) is set as the start position, the X-direction counter is up, and the Y-direction counter is down. Then, the Y counter is read while sequentially increasing in the direction of (0,4661).

  Next, the X counter is incremented and the second line is read out, reading from the (1, 0) address in the (1, 4661) direction, and sequentially reading in this way, thereby (4) b image reading. Can be done.

  Therefore, by reading the A4 width document shown in (2) a in the direction (3), the image can be read without rotating.

  Next, the image layout memory will be described. As described above, by reading the individually stored images such as (5) a and (5) b and writing the image at a desired position in the image layout memory, separate documents as shown in (5) c Images can be combined on memory.

<Description of Printer Unit 2>
The configuration and operation of the printer unit 2 will be described with reference to FIG.

  The image signal input to the printer unit 2 is converted into an optical signal modulated by the exposure control unit 201 and irradiates the photosensitive member 211. The latent image created on the photosensitive member 211 by the irradiation light is developed by the developing device 212. The transfer paper is conveyed from the transfer paper stacking unit 214 or 215 together with the leading edge of the developed image, and the developed image is transferred by the transfer unit 216. The transferred image is fixed on the transfer paper by the fixing unit 217 and then discharged from the paper discharge unit 218 to the outside of the apparatus. The transfer paper output from the paper discharge unit 218 passes through the punch unit 250 and is punched when the punch function is working and is transferred to the sorter 230. When the sort function is working at the sorter 230, When the sort function is not working, the bin is discharged to the top bin of the sorter.

  Next, a method for outputting sequentially read images on both sides of one output sheet will be described.

  The output paper fixed by the fixing unit 217 is once transported to the paper discharge unit 218, and then transported to the re-feeding transfer paper stacking unit 221 via the transport direction switching unit 219 with the paper transport direction reversed. . When the next original is prepared, the original image is read in the same manner as in the above process. However, since the transfer paper is fed from the transfer paper stacking unit 221 for refeeding, the same output paper is eventually obtained. Two original images can be output on the front and back surfaces.

  Next, the trial copy operation most relevant to the present embodiment will be described with reference to the flowcharts of FIGS. 6 to 9 and FIGS.

  FIG. 6 is a flowchart regarding control tasks of the operation unit 123 and the liquid crystal display unit 301.

  This control part is started from the time of power-on and is always in a running state.

  In step S601, it is determined whether or not the engine is in an idle state. The idle state is a state where there is no copy job or any other job being executed. If “YES” is determined here, the process proceeds to step S602 to perform control in an idle state. If NO is determined, the process proceeds to step S603 to determine whether the operation is in progress. If the copy operation is being executed, it is determined as YES, and the process proceeds to step S604 to perform the process during the operation. If NO is determined, the process advances to step S605 to determine whether or not the test copy is in an intermediate state. The intermediate state of the trial copy is a state where the job is once suspended after the trial output of a part of the number of copies is completed, and the operation by the user is allowed during that time. This will be described in detail later.

  If “YES” is determined in the step S605, the process proceeds to a step S606, and the trial copy intermediate state is controlled. If NO is determined, the process returns to step S601.

  In addition to this, individual processing is also performed in an exceptional processing state such as when there is no paper interruption or during jam processing, but this is not particularly relevant to the present invention and is therefore omitted.

  Next, of the control in the idle state of the operation unit 123 executed in step S602 described above, a part related to the trial copy related to the present invention will be described with reference to the flowchart of FIG. In the idle state, a screen as shown in FIG. 10 is displayed. In this state, the user can set copy modes such as set number, paper selection, and sorting. In FIG. 10, reference numeral 500 denotes a trial copy key for setting a trial copy. Normally, this key is not displayed and is displayed according to the mode setting state. This will be described in the following description of FIG.

  In step S701 in FIG. 7, it is determined whether or not a numerical value has been set with the numeric keypad of the key group 205. If YES is determined, the numerical value is set in step S702. This number is retained unless cleared or reset by the user. Thereafter, the process proceeds to step S703.

  If NO is determined in step S702, the process directly proceeds to step S703. Here, it is determined whether or not a mode other than a numeric value, for example, a mode such as paper selection, sorting, and double-sided has been input. If NO, the process proceeds to step S705. If YES, the process proceeds to step S704, and after the input mode is set, the process proceeds to step S705.

In steps S705 and S706, it is determined whether the numeric value is greater than 1 or whether the sort mode is set. If both conditions are YES, the process advances to step S707 to display the test copy key 500 shown in FIG. This is a measure that does not display the non-sort type or the copy of the numerical value 1 because the trial copy has no meaning. In step S708, it is determined whether or not the trial copy key is turned on. If it is ON, the trial copy mode is set to ON in step S710. At this time, as shown in FIG. 11, the trial copy key is reversed in black. If it is determined in step S708 that the trial copy key is not turned ON, or if NO is determined in any of the previous steps S705 and S706, the process proceeds to step S709, and the trial copy mode is turned OFF. To do.

  In step S711, it is determined whether the start key 203 has been pressed. If NO is determined, the process returns to step S701, and the idle process is repeated. If YES is determined, the process proceeds to step S712 to start a copy sequence control task. At this time, data such as the set number, trial copy mode setting, and other mode settings set previously are transferred from the operation unit control task to the copy sequence task.

  Thereafter, the process proceeds to step S713, and after waiting for the copy sequence to be in operation, the idle state is terminated.

  Next, a portion related to the present invention in the control in the copy sequence task will be described with reference to the flowchart of FIG.

  As described above, when the copy sequence task is activated, it is first determined in step S801 whether or not the trial copy mode is set. If YES is determined in this step, the process proceeds to step S802, and the numerical value is set to 1. This is a temporary number used for internal processing different from the number set by the user. In the trial copy mode, a part of the number of copies is printed and the intermediate state is entered once. In step S803, the operation unit control task is notified that a trial copy operation has been started. Upon receiving this notification, the operation unit control task enters the operation of step S604 described above, and switches the display to a screen as shown in FIG.

  In step S804, the copying operation is started. Here, the original is read, and one copy is printed while being stored in the image memory 120. After the operation is completed, the process advances to step S806 to shift to the intermediate state of the trial copy. As a result of this information being sent to the operation unit control task, the process in the trial copy intermediate state in step S606 described above is executed.

  Processing in this intermediate state will be described with reference to the flowchart of FIG. 9 and FIGS.

  In the intermediate state, the screen display of FIG. 13 is performed. In FIG. 13, 601 is a setting change key, 602 is a cancel key, and 603 is a print start key.

  In step S901 in FIG. 9, it is determined whether or not the cancel key 602 has been pressed. If “YES” is determined here, the process proceeds to a step S916 to issue a cancel request to the copy sequence task. In step S917, after determining that the copy sequence is in the idle state, the trial copy intermediate state control is terminated.

  If NO is determined in step S901, the process advances to step S902 to determine whether the setting change key 601 has been pressed and a setting change request has been made. If YES is determined here, the process proceeds to step S911. At this time, the operation unit display is switched to a resetting screen as shown in FIG. In step S911, it is determined whether any of the numeric keys of the key group 205 is pressed and the numerical value is changed. In the case of YES, the set number is newly set in step S912. After the process of S912, or if NO is determined in step S911, the process proceeds to step S913.

  In the resetting screen, a paper selection key 701, a sort setting key 702, a binding margin setting key 703, a density setting key 704, and a double-sided copy setting key 705 are displayed, and these mode changes are allowed in addition to the numerical value. In step S913, it is determined whether or not any of the modes has been changed. If changed, the process proceeds to step S914 to reset the mode.

  After the process of step S914 or if NO is determined in step S913, the process proceeds to step S915, and it is determined whether or not the user has finished the setting change by pressing the close key 706 in FIG. Returns to step S911 again.

  If YES is determined in the step S915, or if NO is determined in the above-described step S902, the process proceeds to a step S903. If it is determined in step S911 to S915 that some setting change has been made, the process proceeds to step S904. At this time, a trial copy key 801 is displayed as shown in FIG. By pressing this button, the user can make a trial copy again based on the mode whose setting has been changed.

  In step S904, it is determined whether or not the trial copy key 801 has been pressed. If YES is determined, the process proceeds to step S909, and a restart is requested for the copy sequence. Here, the changed mode and the mode data set first other than that are passed from the operation unit control task to the copy sequence task.

  If NO is determined in step S904, the process proceeds to step S905. Here, it is determined whether or not the print start key 603 has been pressed. By depressing the print start key 603, the user can end the copy job after performing a copy print for a predetermined number of times described below based on the mode set so far or the reset mode.

  If NO is determined in step S905, the process returns to step S901, and the process in the intermediate state is repeated.

  If YES is determined in the step S905, the process proceeds to a step S906.

  Here, it is determined whether or not the setting has been changed in this intermediate state. If NO is determined, the process proceeds to step S907, and 1 is subtracted from the set number so far and set as a new set number. If it is determined YES, this processing is not performed, and the number reset in this intermediate state or the number set before that is retained as it is.

  After the process of step S907, or if YES is determined in step S906, the process proceeds to step S908, and the trial copy mode is canceled. As a result, the next copy print to be executed is completed after printing the number of digits determined by the above-described method.

  After this processing, the process proceeds to step S909 and a restart request is issued to the copy sequence task. In step S910, after confirming that the copy sequence is in operation, the trial copy intermediate state control is terminated.

  Here, returning to FIG. 8 again, the operation of the copy sequence task from the intermediate state will be described.

  In step S807, it is determined whether a restart request is received from the operation unit control task in the intermediate state. If "NO" is determined here, the process proceeds to a step S809 to determine whether or not a cancel request is received. If NO, the process returns to step S807 again, and the process in the intermediate state is repeated. If “YES” is determined in the step S809, the process proceeds to a step S810 to stop the copy sequence in the suspended state. Thereafter, the process proceeds to step S813. Step S813 and subsequent steps will be described later.

  If YES is determined in the step S807, the process proceeds to a step S808. Here, it is determined whether or not the trial copy mode is still set. If YES is determined, the process returns to step S802, and the trial copy operation is performed again. If NO is determined in the step S808, the process proceeds to a step S811 to notify the operation unit control task that the copy print operation is started. In step S812, the copy print operation is started based on the mode and number data reset at the restart.

  Then, after the operation ends, the process proceeds to step S813 to notify the operation unit control task that the copy operation has ended and returned to the idle state, and then the copy sequence task is ended.

  Note that the original image data stored in the image memory 120 is read first, and the mode set at that time is read at the time of the trial copy print again from the intermediate state and the copy print after releasing the trial copy. Printing is performed by performing the above process.

  With the above control, the trial copy operates as follows.

  First, when the trial copy is set, a part of the copy print is always performed, and then the state shifts to a resettable intermediate state. When the trial copy is performed again in the intermediate state, the same operation as described above is performed.

  In printing by the print start key 603, that is, copy printing after canceling the trial copy mode, the set number is processed as follows.

  First, if the mode is changed in the intermediate state, the set number is used as it is, and printing is performed for the set number. This is because the print result after the mode change is a print result that the user wants to obtain, and the test copy output before that is not considered.

  If the mode is not changed in the intermediate state, the user can presume that the trial copy output earlier is good and is based on the will to print in cascade. In this case, it is considered that the trial copy printed earlier is also effective, and by reducing the number of copies by one copy and performing the remaining copy prints, it is possible to provide printing for the number of copies that the user has obtained. Become.

  In addition, while the trial copy mode is set and trial printing is being performed, one copy is always printed, but the initially set number is not changed.

  In other words, when the user makes a trial copy, it is extremely effective to provide prints for the number of copies desired by the user without recognizing that the number is always changed when the mode is changed.

  Furthermore, although the present invention is applied to copying in the above-described embodiments, the present invention is not limited to this.

  For example, in recent years, a digital copying machine has been devised that has a box function.

  This is provided so that image data transferred from a scanner or an external device is permanently stored in an image memory, and can be printed at any time when the image data is to be printed. Trial printing can be applied to printing from this box, and the application of the present invention is also effective.

  In addition, when the FAX data is received, temporarily stored in the memory, and read and printed by the user's operation, the test print can be applied, and the application of the present invention becomes effective.

  As described above, the present invention can be applied to all devices that can read out and print an image stored in a memory and can change a predetermined mode each time it is read out.
