JP6812711B2 - Cover paper output device - Google Patents

Description

The present invention relates to a cover paper output device.

Conventionally, in the case of printing using an image forming apparatus, a technique has been proposed in which when selecting a paper to be output for an input original, the paper is automatically selected according to the size of the input original.
For example, the image forming apparatus described in Patent Document 1 compares the size of the original image (or the size of the variable magnification image calculated based on the size), which is the detection result by the scanner, with the size of the standard paper, and compares the original image. Alternatively, it is determined whether or not the variable-magnification image fits on the standard paper, and if it does not fit, the size of the rotated image when the original image or the variable-magnification image is rotated 90 degrees or 270 based on the above detection result is calculated. Then, the size of the rotated image is compared with the size of the standard paper to determine whether or not the rotated image fits on the standard paper, and only when the rotated image fits, the original image or the variable magnification image is rotated 90 degrees or 270 degrees. When the original image, the variable magnification image, or the rotated image fits on the standard paper, the paper cassette (standard paper paper feed unit) capable of feeding the standard paper is preferentially selected.

On the other hand, the covering method determining unit 34 tentatively determines the diagonal wrapping as a method of covering the covering when the icon described as "diagonal wrapping" is pressed.

After tentatively determining the method of covering the covering, the covering method determining unit 34 tentatively determines the covering method, the paper size of the paper accommodated in the supply unit 50, and the development of the covering generated by the development drawing generation unit 33. The covering method is finally decided based on the figure information.

FIG. 9A is a diagram showing a case where the developed view of the covering material fits within the paper size. FIG. 9B is a diagram showing a case where the developed view of the covering material does not fit within the paper size.
In the case where the tentatively determined covering method is a book cover or packaging, the covering method determination unit 34 stores the development drawing grasped from the development drawing information of the covering generated by the development drawing generation unit 33 in the paper storage unit 56. When it fits within the paper size of the paper (see FIG. 9A), it is determined that the paper stored in the paper storage unit 56 can be used as a cover paper, and a tentatively determined covering method is used. Determined as the final covering method. Further, the covering method determining unit 34 determines the smallest size of the paper size in which the developed view of the covering is accommodated as the paper for forming the image. Since the paper information stored in the paper storage units 56 of each of the first paper supply unit 51 and the second paper supply unit 52 is stored in the ROM (Read Only Memory), the covering method determination unit 34 can be used in the ROM. The paper information stored in the paper storage unit 56 is acquired from.

On the other hand, in the covering method determination unit 34, when the tentatively determined covering method is a book cover or packaging, the development drawing obtained from the development drawing information of the covering generated by the development drawing generation unit 33 is transmitted to the supply unit 50. If it does not fit within the paper size of the stored paper (see FIG. 9B), it is impossible to use the paper stored in the paper storage section 56 as the cover paper by the selected covering method. to decide. Then, the covering method determining unit 34 notifies via the UI 40 that the selected covering method does not fit within the paper size. In addition, the covering method determination unit 34 presents another covering method to the user.

FIG. 10A is a diagram showing the relationship between the developed view of the caramel wrapping and the paper size. FIG. 10B is a diagram showing the relationship between the development view of the diagonal wrapping and the paper size.
For example, when the tentatively determined covering method is diagonal wrapping, the diagonal wrapping does not fit within the paper size (see FIG. 10B), but the caramel wrapping fits within the paper size (FIG. 10 (Fig. 10). In the case of a)), it is displayed on the UI40 that the diagonal wrapping does not fit in the maximum paper size (A3 size in this embodiment), and that the caramel wrapping fits in the maximum paper size (caramel wrapping). Present).

In addition, if the tentatively determined covering method is packaging, and neither caramel wrapping nor diagonal wrapping fits in the maximum paper size, but if it is Noshi, it fits in the maximum paper size, the selected covering method will fit the maximum paper. Notifies that it does not fit within the size and displays on UI40 that it fits in the maximum paper size if it is Noshi (presents Noshi).
When the user selects the covering method presented via the UI 40, the covering method determining unit 34 determines the selected covering method as the final covering method. Further, the covering method determining unit 34 determines the paper having the smallest size among the feasible paper sizes for the presented covering method as the paper for forming an image.

In the covering method determination unit 34, when the tentatively determined covering method is a book cover or packaging, the development drawing obtained from the development drawing information of the covering generated by the development drawing generation unit 33 is housed in the supply unit 50. It fits within the minimum paper size (A4 size in this embodiment) of the paper, but if it fits at the limit and there is no margin, the minimum paper size cannot be afforded by the selected covering method via UI40. In addition to notifying, paper having a size larger than the minimum paper size (A3 size in this embodiment) may be recommended.
When the user selects the recommended paper size via the UI 40, the covering method determining unit 34 determines the selected paper as the paper for forming an image.

Further, the covering method determining unit 34 has a paper size smaller than the maximum paper size (A4 in the present embodiment) even if the selected covering method fits in the maximum paper size (A3 size in the present embodiment). If the size does not fit in the size), a notification to that effect may be given and a paper size smaller than the maximum paper size may be recommended.
When the user selects the recommended paper size via the UI 40, the covering method determining unit 34 determines the paper of the selected paper size as the paper for forming the image.

When the tentatively determined covering method is Noshi, the covering method determining unit 34 has a long side length in the middle of three different side lengths (x, y, z) of a rectangular parallelepiped which is a covering. It is determined whether or not there is a paper longer than the length (y when x> y> z). Then, in some cases, the covering method determining unit 34 determines the paper as the paper for forming an image. When there are a plurality of sheets, the covering method determining unit 34 determines the minimum size (A4 size in the present embodiment) paper among them as the paper for forming an image. On the other hand, if there is no paper, the covering method determination unit 34 notifies via the UI 40 that there is no paper that can be used as a Noshi.

For example, the image determination unit 35 derives the position of the crease based on the covering method determined by the covering method determination unit 34 and the development drawing information of the covering generated by the development drawing generation unit 33, and serves as an image to be given to the paper. , As shown in FIG. 11, it is determined to add the broken line 35a as the crease information. Although the broken line 35a as the crease information is shown in black in FIG. 11, the color of the broken line 35a is not particularly limited. It may be formed transparently with clear toner.

Further, the image determination unit 35 may determine the image to be given to the paper to the characters or figures selected by the user via the UI 40. It can be exemplified that the characters and figures are the characters and figures input by the user into the UI 40. As the characters input to the UI 40 by the user, it can be exemplified that the characters are described in a book cover such as "** bookstore" (see FIG. 11B). Further, it can be exemplified that the image given to the paper is a character or figure selected by the user from the characters or figure displayed on the display unit of the UI 40. The characters displayed by the image determination unit 35 on the display unit of the UI 40 are generally used as terms to be described in the table of Noshi such as "summer greetings", "year-end gifts", "celebration", "thank you", and "shou". It can be exemplified that it is a character used in (see FIG. 11 (a)).

The image determination unit 35 may determine the position and orientation of forming characters and figures as an image to be given to the paper at the position and orientation selected by the user via the UI 40. For example, the image determination unit 35 causes the UI 40 to display a development drawing based on the development drawing information of the covering material generated by the development drawing generation unit 33, and displays a surface selected based on the displayed development drawing as characters or figures. It is good to decide as the position to form. Also, it may be possible to finely select the central part, the upper part, the lower part, the central right part, the central left part, the upper right part, the upper left part, the lower right part, the lower left part, etc. on the selected surface. good. Further, it is preferable that the direction in which the character or the figure is formed can be finely selected, such as the direction parallel to the long side on the selected surface or the direction parallel to the short side on the selected surface. FIG. 11 shows a case where characters are formed in the center of the selected surface so as to be oriented parallel to the long side.
In the case where the covering method is a book cover and the UI 40 is to display a development drawing based on the development drawing information of the covering generated by the development drawing generation unit 33, the image determination unit 35 is shown in FIG. As shown in b), it is preferable to arrange the book cover so that the spine of the book cover is between the front and back surfaces.

FIG. 12 is a diagram showing an example of a preview screen displayed on the user interface.
When the image determination unit 35 determines the position and orientation of forming characters and figures as an image to be given to the paper, the image determination unit 35 causes the display unit of the UI 40 to display an image of the cover paper in a state of covering the covering. It may prompt the user to make a final decision. As shown in FIG. 12, the image determination unit 35 is described with the image of the cover paper, the icons described as "decision" and "return", and "+" and "-" for enlarging and reducing the image. It is advisable to display an icon, an icon indicating the direction in which the image is rotated, etc. on the preview screen.

Further, the image determination unit 35 may add an image read by the image reading unit 10 as an image to be applied to the paper. For example, the image determination unit 35 causes the UI 40 to display a development drawing based on the development drawing information of the covering generated by the development drawing generation unit 33, and selects a surface to which the image read by the image reading unit 10 is to be attached. It is preferable to place the object with the image on the platen glass 111a and instruct the image reading unit 10 to read the image. After the image reading unit 10 reads the image, the image determining unit 35 may arrange a thumbnail of the image read by the image reading unit 10 on the surface selected by the user on the preview screen displayed on the UI 40.

Then, the image determination unit 35 may finally determine the image to be given to the paper when the user presses the icon described as "decision" on the preview screen displayed on the UI 40.
Then, the image forming unit 35 forms the image determined by the image determining unit 35 on the paper (first sheet P1 or second sheet P2) determined by the covering method determining unit 34. , Outputs a command to the supply unit 50.

As described above, the image forming apparatus 1 is developed as an example of a paper accommodating unit 56 as an example of an accommodating unit for accommodating paper and a grasping unit for grasping dimensional information of a packaged object (an example of a covering). Based on the dimensional information of the paper stored in the figure generation unit 33 and the paper storage unit 56 and the dimensional information of the object to be packaged grasped by the developed drawing generation unit 33, the paper stored in the paper storage unit 56 is stored. It functions as a wrapping paper output device including a covering method determining unit 34 as an example of a determining unit for determining whether or not it can be used as a wrapping paper for wrapping an object to be packaged. Then, the image forming apparatus 1 configured in this way can automatically output the paper that can be used as the wrapping paper.

As described above, the development drawing generation unit 33 generates the development drawing information of the packaged object (an example of the covering) based on the grasped dimensional information, and the covering method determination unit 34 has the development drawing of the packaged object. If it fits within the size of the paper stored in the paper storage unit 56, it is determined that it can be used as a wrapping paper. Therefore, the covering method determination unit 34 can accurately determine that the paper stored in the paper storage unit 56 can be used as the wrapping paper.
Further, the paper accommodating unit 56 accommodates a plurality of sheets of different sizes (first sheet P1, second sheet P2), and the covering method determining unit 34 accommodates a developed view of the object to be packaged in the sheet accommodating unit 56. If it does not fit in the maximum size of the plurality of papers, it is judged that it cannot be used as a wrapping paper. Therefore, the covering method determining unit 34 can accurately determine that any of the papers contained in the paper accommodating unit 56 cannot be used as the wrapping paper.

Further, the image forming apparatus 1 further includes a user interface (UI) 40 as an example of a receiving means for receiving one of the plurality of packaging methods from the user, and the covering method determining unit 34 further includes the plurality of packaging methods.

<Second Embodiment>
The image forming apparatus 1 according to the second embodiment has a different mechanism for detecting the rotation angle θ of the document feeding unit 120 with respect to the image forming apparatus 1 according to the first embodiment. Hereinafter, the points different from the first embodiment will be described.

FIG. 13 is a view of the image reading unit 10 according to the second embodiment as viewed in the direction III of FIG.
The document feed unit 120 according to the second embodiment rotates around a rotation axis 114 attached to the housing 113 of the scanner unit 110, and has a curved surface whose distance from the rotation center differs depending on the rotation angle. It has a rotating member 132.
Further, the scanner unit 110 has a distance detection sensor 115 which is arranged in a portion of the housing 113 facing the curved surface of the rotating member 132 and detects the distance to the curved surface of the rotating member 132.

Then, the side grasping unit 32 according to the second embodiment has a document feeding unit 120 based on an output value (information about the distance of the rotating member 132 to the curved surface) from the distance detection sensor 115 arranged in the scanner unit 110. The thickness of the coating material mounted on the platen glass 111a based on the grasped rotation angle θ (the length in the direction orthogonal to the surface mounted on the platen glass 111a (= z)). To grasp.

In the image forming apparatus 1 according to the second embodiment configured as described above, for example, the rigidity of the document feed portion 120 is small, and the inclination angle of the portion on the rotation center side and the inclination angle of the portion on the tip side are different. Even when the tilt sensor 131 arranged inside the document feed unit 120 has high accuracy and it is difficult to detect the rotation angle θ, the distance detection sensor 115 detects the distance to the curved surface of the rotating member 132 with high accuracy. Therefore, the side grasping unit 32 grasps the rotation angle θ of the document feeding unit 120 with high accuracy, and grasps the thickness (= z) of the covering with high accuracy. Further, it is not necessary to increase the rigidity of the document feed unit 120. As a result, deformation of the coating material when measuring the thickness of the coating material is suppressed due to the increase in the rigidity of the document feed portion 120.

<Third Embodiment>
The image forming apparatus 1 according to the third embodiment is different from the image forming apparatus 1 according to the second embodiment in that it includes a measuring member 140 for measuring the thickness of the coating. Hereinafter, the points different from the second embodiment will be described.

FIG. 14 is a view of the image reading unit 10 according to the third embodiment as viewed in the direction III of FIG.
