  In the image forming apparatus proposed in Patent Document 1, the Nup setting can be canceled / set while checking the layout preview, and the layout of the Nup setting can be easily set, which is proposed in Patent Document 2. In the image forming apparatus, complicated Nup setting can be performed while checking the layout preview. However, in the techniques proposed in Patent Document 1 and Patent Document 2, no consideration is given to selecting an arbitrary document image from document images to be consolidated and performing consolidated printing.

  In the print control apparatus proposed in Patent Document 3, arbitrary one or more pages of print target data is selected from a plurality of continuous pages of print target data to form one set, and different aggregation settings are performed for each set. However, in order to select print target data constituting a group and perform aggregate setting in each group, it is necessary to call and operate a setting screen for each group, which is complicated. In addition, since the preview after the aggregation setting is not displayed, it is possible to check again whether or not the page on which the aggregation setting has been performed is correctly selected and whether the aggregation number in the aggregation setting has been correctly set. It is necessary to call and operate the setting screen for each group, and there is room for further improvement in improving operability.

  An object of the present invention is to select an arbitrary document image from a series of target document images by a simple operation in a series of aggregate editing operations in view of the above-described conventional technology, and to perform aggregate editing in a desired order. An object of the present invention is to provide an image forming apparatus capable of easily confirming the contents of the collective editing.

  According to the above-described configuration, the preview image selecting means is provided in association with the selected aggregate number setting key so that the document image to be aggregated and edited can be arbitrarily selected from the preview images of the target series of document images. Therefore, it is possible to perform the collective editing of arbitrary document images desired to be consolidated without being limited by the reading order of the series of document images. Furthermore, it is possible to select a document image to be aggregated and set the number of aggregates for the selected document image by a series of simple operations.

Since only the original image that needs to be printed can be printed, the cost caused by unnecessary resource consumption can be reduced, and it is not necessary to select a preview image of the original image that does not require printing. The time required can be shortened.

For example, when “Patent Publication” is used as a manuscript, the “claim” preview image is skipped, and the “bibliography”, “summary”, and “detailed description” preview images are displayed as “detailed description” and “bibliography”. ”And“ summary ”in order, the document images of“ bibliography ”,“ summary ”, and“ detailed description ”can be collectively edited in the selection order.

  In the third feature configuration, as described in claim 3, in addition to the first or second feature configuration described above, the preview display unit displays the preview image selected by the preview image selection unit, It is in the point which displays in the aspect which can visually recognize the relationship with the aggregation number setting key matched.

  According to the above-described configuration, it is possible to easily determine which preview image of the original image has been subjected to the aggregate editing setting, and further, by visually recognizing the preview image of the original image that has been subjected to the aggregate editing setting, It is possible to easily know how many consolidated sheets are set in the image. Further, by visually recognizing the preview image, it is possible to easily identify a document image that has not been subjected to the aggregation editing setting, or a document image that has the incorrect aggregation editing setting from among the document images that have been subjected to the aggregation setting.

  In the fourth feature configuration, as described in claim 4, in addition to any one of the first to third feature configurations described above, the preview display means includes a preview image selected by the preview image selection means. Is provided with aggregated layout display means for switching to the layout after the aggregate editing.

  According to the above-described configuration, it becomes clear at a glance which other original image the document image that has been set for aggregate editing is to be aggregated, and the layout serves as a guideline for correction of the aggregate editing, and the layout is visually recognized. By doing so, it is possible to confirm the configuration of the output material when executing aggregate printing in a specific form.

  As described above, according to the present invention, an arbitrary document image can be selected from a series of target document images by a simple operation in a series of aggregate editing operations, and can be collectively edited in a desired order.

If not (S8), when the start key is pressed (S11), the centralized printing of the original image excluding the unselected original image among the read original images is executed with the integrated editing content (S12).

  Another embodiment will be described below. In the above-described embodiment, the preview image 110d selected by the preview image selection unit 102a is displayed together with the outer frame attached to the same color as the color assigned to the aggregate number setting key 110a. The preview image 110d may be configured to display the preview image 110d by applying the color applied to the aggregated number setting key 110a to the preview image 110d at a low density, and the contents of the preview image 110d can be identified. Any device can be used as long as it can be determined whether or not it is associated with the number setting key 110a.

  In the above-described embodiment, the page number given in the order of reading is applied to the preview image 110d of the read original image in a translucent manner, but the preview image 110d can be identified so that the contents of the preview image 110d can be identified. The configuration may be applied to the header portion and the footer portion of 110d, or may be configured to not apply the page number. In the case of using a configuration without page numbers, it is desirable that the content of the preview image 110d is displayed in a state where it can be accurately identified.

  In the above-described embodiment, different colors are assigned to the aggregated number setting key 110a. However, a configuration may be used in which identification means such as density and gradation, different textures, patterns, and characters are added. However, the identification means needs to be able to determine which aggregate number setting key 110a the preview image 110d is associated with when the preview image 110d is attached to the preview image 110d. It is necessary not to adopt what may cause the content of 110d to become unidentifiable, or to attach it to the preview image 110d, such as attaching it to its header or footer, or attaching it in a semi-transparent state.

  In the above-described embodiment, when there is an unselected preview image 110d, it is configured to set whether or not to print the corresponding document image. However, all the document images are printed without setting. A configuration may be employed, and a configuration may be employed in which a document image corresponding to an unselected preview image 110d is not printed. In this case, although convenience cannot be denied, the time required for the collective editing work can be shortened, and the use efficiency of the multifunction device 1 is improved.

  In the above-described embodiment, the preview image 110d is displayed in the layout after the aggregate editing before executing the aggregate printing. However, the preview printing 110d is not displayed in the layout after the aggregate editing, and the aggregate printing is performed. Also good. In this case, although convenience cannot be denied, the time required for the collective editing work can be shortened, and the use efficiency of the multifunction device 1 is improved.

  In the above-described embodiment, the selected preview image 110d is displayed in a manner in which the association associated with the aggregated number setting key 110a is visible. However, the association associated with the aggregated number setting key 110a is not visually recognized. Thus, the selected preview image 110d may be displayed. In this case, it is difficult to determine the contents of the aggregate editing unless the aggregate printing is executed, but it is possible to reduce the load on the CPU or the like used for displaying the preview image 110d or the like.

  In the above-described embodiment, the aggregation editing unit 130 performs the aggregation editing in the order selected by the preview image selection unit 102a. However, the aggregation editing unit 130 may perform the aggregation editing in the order of reading. However, when there is a document image to be rearranged, it is necessary to rearrange the actual document when reading the document, which may be cumbersome, but the time required for the collective editing operation is short. The use efficiency of the multifunction device 1 is improved.

  Any of the above-described embodiments is merely an example of the present invention, and it is needless to say that the specific configuration and the like of each block can be appropriately changed and designed within the scope of the effects of the present invention.
