Abstract

[Problem] To easily digitize images representing multiple documents into a consolidated image arranged in a user-desired configuration. [Solution] The control unit 291 displays a settings screen on the display unit 24, and the input receiving unit 23 receives settings input from the user. When the input receiving unit 23 receives a command to execute a scan, the image reading device 20 reads the document placed on the document tray 33. The images acquired by the image reading device 20 are stored in the image memory 26. After all documents have been read, the image generation unit 28 reads the image data from the image memory 26 and generates a composite image according to the sheet size, page orientation, arrangement method, and output method set by the user.

  2. The image reading device according to claim 1, further comprising a control unit that causes the image reading unit to read the image of the document after the input receiving unit has received the setting input for the arrangement method.
  3. A document tray on which multiple documents are placed, A linear transport path that transports documents, one by one, that are pulled out from a plurality of documents placed on the document tray, and discharges the documents to a first discharge tray, The system further includes a curved transport path that branches off from the straight transport path and discharges the document to a second discharge tray different from the first discharge tray, The image reading unit comprises a first image reading unit provided on the straight transport path and a second image reading unit provided on the curved transport path. The image reading device according to claim 2, wherein when the control unit receives an instruction from the input reception unit to generate the aggregated image while a document is placed on the document tray, the control unit transports the document along the linear transport path and has the first image reading unit read the document.
  4. The image reading device according to claim 1, wherein when the input receiving unit receives a size specification instruction specifying the size of the sheet, the image generation unit acquires size information indicating the size of each of the multiple originals, calculates the number of images that can be placed within the area specified by the size specification instruction using the corresponding original size of each image stored in the image storage unit, and generates the aggregated image by placing the calculated number of images on the sheet for one page.
  5. An image reading device according to any one of claims 1 to 3, An image forming unit that prints an image onto paper, An image forming apparatus equipped with [a specific feature].
  6. The image reading device according to claim 2 or claim 3, An image forming unit that prints an image onto paper, It includes a data storage unit for storing data, The input receiving unit receives a selection instruction for one of the following methods for outputting the aggregated image: the storage unit stores the aggregated image, the image forming unit prints the image indicated by the aggregated image, or the storage unit stores the aggregated image and the image forming unit prints the image indicated by the aggregated image. The control unit controls the output of the aggregated image according to the output method of the aggregated image received by the input receiving unit, in an image forming apparatus.

Description

This invention relates to an image reading apparatus and an image forming apparatus. In recent years, image reading devices capable of scanning and digitizing large quantities of business cards and other documents have become known. These image reading devices either scan images of documents (business cards) placed on a platen glass, or scan images of documents placed on a document tray as they are pulled along a transport path. Patent Document 1 describes a method for easily identifying the original documents from which each image originated, even when multiple types of documents are scanned together. Japanese Patent Publication No. 2012-034330 This is a front cross-sectional view of an image forming apparatus.This is a front cross-sectional view of the image reading device.This is a perspective view showing the external appearance of the image reading device.This diagram shows a magnified view of the document transport path in an image reading device.This diagram shows an enlarged view of an alternative document transport path in an image reading device.This is a block diagram showing the internal configuration of an image forming apparatus.This diagram shows an example of a settings screen displayed on the display unit.This figure shows an example of how images are arranged.This figure shows an example of how images are arranged.This figure shows an example of how images are arranged.This figure shows an example of how images are arranged.This figure shows an example of how images are arranged.This is a flowchart illustrating the process of reading a document using an image reader. The following describes one embodiment of the present invention with reference to the drawings. Figure 1 is a cross-sectional view showing an image forming apparatus to which an image reading device according to one embodiment of the present invention is applied. As shown in Figure 1, the image forming apparatus 10 comprises an image reading device 20 and an image forming unit 21. In this embodiment, an image forming unit 21 employing an electrophotographic method is used as an example, but an image forming unit employing an inkjet method may also be used. The image reading device 20 has an imaging unit (CCD sensor, contact image sensor) that optically reads the image of the document. The analog output of this imaging unit is converted into a digital signal to generate image data representing the image of the document. The image forming unit 21 prints the image shown by the image data onto the paper and includes an image forming unit 3M for magenta, an image forming unit 3C for cyan, an image forming unit 3Y for yellow, and an image forming unit 3Bk for black. In each of the image forming units 3M, 3C, 3Y, and 3Bk, the surface of the photoreceptor drum 4 is uniformly charged, the surface of the photoreceptor drum 4 is exposed to light to form an electrostatic latent image on the surface of the photoreceptor drum 4, the electrostatic latent image on the surface of the photoreceptor drum 4 is developed into a toner image, and the toner image on the surface of the photoreceptor drum 4 is transferred to the intermediate transfer belt 5. This forms a color toner image on the intermediate transfer belt 5. This color toner image is then secondary transferred to the paper P transported from the paper feeding unit 14 through the main transport path 8 in the nip area N between the intermediate transfer belt 5 and the secondary transfer roller 6. Next, the fixing device 15 heats and pressurizes the paper P to fix the toner image on the paper P by thermal compression, and then the paper P is discharged through the discharge roller 16 to the output tray 17. Furthermore, when the image of the original document M is to be printed on the back side of the paper P, the paper P is transported to the discharge roller 16 in front of the output tray 17. A switchback transport is performed by briefly stopping the discharge roller 16 and then reversing its rotation. The paper P is then returned to the main transport path 8 via the reverse transport path 9 from the transport roller 18, reversing the front and back sides of the paper P. The image forming unit 21 then forms the image of the original document M on the back side of the paper P, and the paper P is discharged into the output tray 17 via the discharge roller 16. Next, the image reading device 20 of this embodiment will be described. Figure 2 is a cross-sectional view showing the image reading device 20 of this embodiment. Figure 3 is a perspective view showing the external appearance of the image reading device 20, with the document transport unit 31 in the open position. As shown in Figures 2 and 3, the image reading device 20 comprises a document transport unit 31 and a reading unit 32. The document transport unit 31 includes a document tray 33, a paper feed roller 34, a transport belt 35, a retard roller 36, a registration roller 37, multiple transport rollers 38, a first discharge roller
