  According to an information processing program described in the embodiments of the present specification, a control device that executes control according to the information processing program, an image reading device including the control device and an image reading unit, an image reading method, an image reading system, and the like The specific screen is displayed when it is determined that the length of the side of the document read by the image reading unit in the orthogonal direction orthogonal to the conveyance direction is equal to or longer than the first length. After the specific screen is displayed, the specific reading process is executed in response to accepting the setting value setting. The specific reading process includes a process for generating specific image information from the read image information corresponding to the original to be read in accordance with the received set value. Therefore, in a specific reading process, that is, a process in which a document whose contents are described with the longitudinal direction as the top and bottom is read in the direction of the document with the short direction as the top and bottom, an image according to the original intention can be acquired. In the claims, the term “orthogonal direction orthogonal to the direction of conveyance” does not limit that the direction is strictly orthogonal to the direction of conveyance, and the document is orthogonal to the conveyance direction during conveyance. Including the case of tilting to an appreciable level.

  According to the information processing program or the like described in the embodiment of the present specification, in response to receiving the setting value setting used in the specific reading process, the read image information is processed into the specific image information according to the received setting value. Is done. Therefore, an appropriate setting value can be set according to the rotation direction of the document, and thus an image in accordance with the original intention can be acquired in the specific reading process.

  According to the information processing program or the like described in the embodiment of the present specification, in response to receiving a setting value setting used in the specific reading process, the read image information is processed into specific image information according to the received setting value. Is instructed to the image reading unit. Therefore, the image reading unit can be processed according to an appropriate setting value in accordance with the rotation direction of the document, so that an image according to the original intention can be acquired in the specific reading process.

  According to the information processing program or the like described in the embodiment of the present specification, the specific screen is displayed when it is determined that the length of the side in the orthogonal direction is equal to or longer than the first length. When it is determined that the length of the side in the orthogonal direction is not equal to or longer than the first length, there is a high possibility that the specific reading process is intended. You can get. On the other hand, the display of the specific screen is limited in response to the determination that the length of the side in the orthogonal direction is not greater than or equal to the first length. When it is determined that the length of the side in the orthogonal direction is not equal to or longer than the first length, there is a high possibility that the specific reading process is not intended, so it is not necessary to set a setting value used in the specific reading process. It is possible to suppress the setting value from being set unnecessarily via the specific screen.

  According to the information processing program or the like described in the embodiment of the present specification, the specific screen is displayed in response to the execution permission setting for the specific reading process being set. Therefore, when the execution permission setting for the specific reading process is set, the setting value can be set via the specific screen, so that an image according to the original intention can be acquired in the specific reading process.

  According to the information processing program or the like described in the embodiment of the present specification, it is determined that the length of the side in the orthogonal direction is equal to or longer than the first length and that the execution permission setting for the specific reading process has not been set. Accordingly, a setting screen for selecting whether to set the execution permission setting is displayed. In response to the display of the setting screen in this manner, the specific screen is displayed after the display in response to the selection of setting the execution permission setting. Even if there is a high possibility that the specific reading process is intended, if the execution permission setting for the specific reading process is not set, it is possible to select whether or not to set the execution permission setting via the setting screen. it can. Therefore, the specific reading process can be executed as intended, and an image in accordance with the original intention can be acquired in the specific reading process.

  In particular, when it is determined that the length of the side in the orthogonal direction is equal to or longer than the first length and the execution permission setting for the specific reading process has not been set, the setting screen sets the execution permission setting. It is displayed in a manner that recommends the selection to be made. Therefore, when there is a high possibility that the specific reading process is intended, the execution permission setting is not set, and an image according to the original intention can be acquired.

  According to the information processing program or the like described in the embodiment of the present specification, it is determined that the length of the side in the orthogonal direction is equal to or longer than the first length and that the execution permission setting for the specific reading process has not been set. Accordingly, the setting screen is displayed regardless of the setting of whether to display the setting screen. Therefore, even if there is a high possibility that the specific reading process is intended, if the execution permission setting for the specific reading process is not set, even if the setting screen is not displayed, the setting screen is not displayed. It is possible to select whether to set permission settings. Thereby, the specific reading process can be executed as intended.

  According to the information processing program or the like described in the embodiment of the present specification, the length of the side in the orthogonal direction is equal to or longer than the first length, and the original to be read is an original of a first predetermined size. The execution permission setting is set when it is determined that there is a possibility that the document has a short side having a length substantially equal to the length of the long side and is larger than the first predetermined size and has a second predetermined size. A setting screen for selecting whether or not to perform is displayed. Even if the original document of the first predetermined size is erroneously determined as the original document of the second predetermined size, the execution permission setting is set via the setting screen. Settings can be made. Therefore, in the specific reading process, an image according to the original intention can be acquired. On the other hand, when the document to be read is a document of the second predetermined size, the specific reading process is erroneously executed even though the document of the second predetermined size is the document to be read. Can be suppressed.

  The “original document having a second predetermined size larger than the first predetermined size and having a short side having a length equal to the length of the long side of the first predetermined size document” means the first predetermined size. It is intended that the length of the long side and the length of the short side of the second predetermined size are not completely coincident and include some difference depending on the paper standard. For example, when the first predetermined size is a letter size, the length of the long side of the letter size and the length of the short side of the A3 size do not completely match, but an A3 size original is “first predetermined size”. This corresponds to “a document having a second predetermined size larger than the first predetermined size and having a short side having a length equal to the length of the long side of the original having a size”.

  According to the information processing program or the like described in the embodiment of the present specification, it is determined that the length of the side in the orthogonal direction is equal to or longer than the first length and that the execution permission setting for the specific reading process has not been set. Accordingly, the execution permission setting is set. Therefore, the execution permission setting can be easily set without performing a complicated operation.

  According to the information processing program or the like described in the embodiment of the present specification, it is determined that the document is placed on the document placement unit, and the length of the side in the orthogonal direction is determined. Then, a reading instruction for reading the original while conveying the original is output to the image reading unit. Therefore, it is possible to prevent the image reading unit from starting reading the document in a state where the document to be read is not placed on the document placing unit.

  According to the information processing program or the like described in the embodiment of the present specification, the length of the side in the orthogonal direction is determined in response to the reading instruction for reading the document being conveyed to the image reading unit. Judgment is made. Therefore, after the image reading unit starts reading the document, it is possible to determine whether or not to execute the specific reading process according to the determination of the length of the side in the orthogonal direction.

  According to the information processing program or the like described in the embodiment of the present specification, based on the reception of the setting value regarding the rotation direction of the read image information via the specific screen, the read image information is rotated. A process of rotating in the rotation direction according to the setting value related to the direction is executed as a process for generating specific image information. Therefore, since the read image information can be rotated in an appropriate rotation direction according to the document orientation, an image according to the original intention can be acquired in the specific reading process.

  In particular, the process of rotating the read image information in the rotation direction corresponding to the setting value regarding the rotation direction of the image information based on the reception of the setting value setting regarding the document size via the specific screen, and the document size The process of cutting out to a size corresponding to the set value for the process is executed as a process for generating specific image information. Therefore, since the read image information can be cut out from the read image after rotation with an appropriate document size, an image in accordance with the original intention, such as an output image in which a necessary portion is cut out in the specific reading process, can be obtained. Can get.

  According to the information processing program or the like described in the embodiment of the present specification, the length of the side of the document read by the image reading unit in the orthogonal direction orthogonal to the conveyance direction is equal to or greater than the first length. In response to the determination, a suggestion screen that suggests setting the execution permission setting for the specific reading process is displayed. After the suggestion screen is displayed, the specific reading process is executed in response to accepting the setting of the execution permission setting via the suggestion screen. The specific reading process includes a process for generating specific image information from the read image information corresponding to the original to be read in accordance with the received set value. Therefore, an image in accordance with the original intention can be acquired in a process of reading a document whose contents are described with the longitudinal direction as the top and bottom in the direction of the document with the short direction as the top, that is, the specific reading process.

  In the claims and the specification, the term “information” and the term “data” use “information” as a superordinate concept of “data”. Therefore, the description “A data” may be rephrased as “A information”. In addition, even if the format (for example, text format, binary format, flag format, etc.) is changed for each computer, “data” and “information” have the same data and information as long as they are recognized as the same meaning content. Are treated as For example, information indicating “two” is stored as text information “0x32” in ASCII code in one computer, and binary format information “10” in binary notation in another computer. May be. However, the distinction between “data” and “information” is not strict, and exceptional handling is allowed.

Thereby, the PC 10 can connect to the server 200 on the Internet 800.

  The scanner 30 is a device that can execute a document reading process. The scanner 30 includes a control unit 31, a reading unit 32, an ADF 33, an ADF sensor 34, a document width sensor 35, an A3 size sensor 36, and a communication unit 37. The control unit 31 includes a CPU, a ROM, and a RAM (not shown) and controls the operation of the scanner 30. When receiving a scan execution instruction from the PC 10, the control unit 31 executes a document reading process and transmits read image data based on the reading process to the PC 10.

  The reading unit 32 is a line image sensor including reading elements 32a (see FIG. 1B) arranged in a predetermined direction. As the reading element 32a, various reading elements such as CIS (abbreviation of Contact_Image_Sensor) and CCD (abbreviation of Charge_Coupled_Device) can be adopted. The reading unit 32 reads a document conveyed on a conveyance path (not shown) provided in the scanner 30 and outputs image data generated by the reading to the control unit 31.

  The ADF 33 includes a paper feed tray (not shown), and transports a document placed on the paper feed tray, that is, a document to be read, to a reading position by the reading unit 32 along a transport path and reads the document. The document read by the unit 32 is conveyed to a paper discharge tray (not shown) along a paper discharge path (not shown). The ADF sensor 34 is a sensor that detects whether a document that can be transported by the ADF 33 is placed on the paper feed tray, and sends a signal to the control unit 31 according to whether or not the document is placed on the paper feed tray. Output. As the ADF sensor 33, for example, a known sensor such as an optical sensor or a contact sensor can be used. Based on the signal input from the ADF sensor 34, the control unit 31 determines whether or not a document that can be transported by the ADF is placed on the paper feed tray.

To 31. The control unit 31 detects the document width of the document to be read based on the signal acquired from the document width sensor 35. When receiving an inquiry from the PC 10, the control unit 31 outputs information indicating the detection result (hereinafter referred to as “document width information”) to the PC 10.

  Note that the “direction orthogonal to the conveyance direction” is not intended to be limited to being strictly orthogonal to the conveyance direction, but is inclined to such an extent that the document can be regarded as orthogonal to the conveyance direction during conveyance. Including cases. For example, when transporting the short side of A4 size along the transport direction, if the position of the short direction transport direction front end and transport direction end is inclined to be within 2 mm, the A4 size long The sides and the transport direction are considered to be orthogonal.

  The A3 size sensor 36 is a sensor that detects whether or not the document to be read is a vertically oriented A3 size document. The “vertical orientation” is an orientation in which the longitudinal direction of the document is the document conveyance direction. On the other hand, the direction in which the short side direction of the document is the document conveyance direction is referred to as “lateral direction”. As the A3 size sensor 36, for example, a known sensor such as an optical sensor or a contact sensor can be employed. The A3 size sensor 36 detects a vertically oriented A3 size original placed on the paper feed tray on the paper feed tray, but the length of the conveyance direction is shorter than the length of the short side of the A4 size. Is provided at a position where it is not detected.

  The A3 size sensor 36 outputs a signal to the control unit 31 according to whether or not a vertically oriented A3 size document is placed on the paper feed tray.

  FIG. 1B is a schematic diagram for explaining the ADF high-speed mode. The “ADF high-speed mode” is one of setting items that can be set for the scanner driver 14a. When the scanner 30 supplies a document to be read using the ADF 33, the document is read. This is an item for setting the length of time required for. When the ADF high-speed mode is valid, the time required to read the original can be shortened compared to when the ADF high-speed mode is invalid.

  When the document reading process is executed with the ADF high-speed mode disabled, the document P is placed on the paper feed tray so that the document P is vertically oriented, that is, the longitudinal direction is the document transport direction (arrow A direction). To do. The document P placed vertically is conveyed by the ADF 33 so that its longitudinal direction is along the conveyance direction, and is read by the reading unit 32. The reading unit 32 uses a reading element 32a having a reading width corresponding to the length L2 in the short direction of the original P among the reading elements 32a arranged in the sub-scanning direction (arrow B direction). Read P.

  On the other hand, when the document reading process is executed with the ADF high-speed mode enabled, the document P is placed on the paper feed tray so that the document P is in the landscape orientation, that is, the short side direction is the document transport direction (arrow A direction). Place. Accordingly, the document P placed sideways is transported by the ADF 33 so that the short side direction is along the transport direction, and is read by the reading unit 32. The reading unit 32 uses the reading element 32a having a reading width corresponding to the length L1 in the longitudinal direction of the original P among the reading elements 32a arranged in the sub-scanning direction (arrow B direction), and the original P corresponding to the length L2. Read.

  While the reading width by the reading unit 32 when the ADF high-speed mode is valid is wider than that when the mode is invalid, the conveyance distance required for reading the document P when the ADF high-speed mode is valid is as follows. Compared with the case where the mode is invalid, the length is shortened by (L1-L2). When the orientation of the document P placed on the paper feed tray is changed from portrait orientation to landscape orientation, the size of the document P is larger than the amount of time required to read the document due to the increase in the reading width by the reading unit 32. When the amount of reduction in the time required for reading the document P accompanying the decrease in the transport distance required for reading the document P is larger, the document P having the size is placed sideways to place the document P Time required for reading can be reduced.

  FIG. 2 is a flowchart showing scan processing executed by the CPU 11 in accordance with the scanner driver 14a. This process is started when the CPU 11 receives a scan execution instruction input via the user interface of the application 14b. The CPU 11 merges various scan settings such as the document size and resolution set for the application 14b and various scan settings such as the document size and resolution set for the scanner driver 14a (S201). ). By the process of S201, the scan setting input via the user interface of the application 14b is reflected.

  The CPU 11 obtains the document width information by inquiring the scanner 30 for the document width information (S202). Based on the acquired document width information, the CPU 11 determines whether the document width of the document to be read is a width corresponding to the long side of A4 size (S203). In the present embodiment, when the document width indicated by the acquired document width information is equal to or longer than a length obtained by subtracting a predetermined value such as 2 mm from 297 mm which is the length of the long side of the A4 size, the CPU 11 determines in S203. Affirm the judgment. On the other hand, when the document width indicated by the acquired document width information is less than the value obtained by subtracting the predetermined value from 297 mm, the CPU 11 denies the determination in S203. In addition, as said predetermined value, it is a value more than 0, and when subtracting from 297 mm, the value which is not shorter than the length of the short side of A4 size is employable suitably.

  When the CPU 11 affirms the determination in S203 (S203: Yes), the CPU 11 determines whether there is a possibility that the document to be read is a portrait-oriented A3 size document (S204). The CPU 11 makes the determination in S204 based on the A3 size information acquired by inquiring of the scanner 30. Specifically, when the acquired A3 size information indicates that a vertically oriented A3 size document is placed on the paper feed tray, the CPU 11 affirms the determination in S204. On the other hand, when the acquired A3 size information indicates that a vertically oriented A3 size document is not placed on the paper feed tray, the CPU 11 denies the determination of S204.

  When the CPU 11 denies the determination of S204 (S204: No), the CPU 11 determines whether or not the ADF high-speed mode is set to be effective for the scanner driver 14a (S205). When the CPU 11 determines that the ADF high-speed mode is not set to be valid, that is, is set to be invalid (S205: No), the CPU 11 proceeds to S206. On the other hand, also when CPU11 affirms the judgment of S204 (S204: Yes), CPU11 transfers a process to S206.

  In S206, the CPU 11 displays on the LCD 18 a user interface (hereinafter referred to as “driver UI”) for setting scan settings for the scanner driver 14a. Next, the CPU 11 displays a guidance display for setting (that is, enabling) the ADF high-speed mode, which is one of setting items that can be set on the driver UI (S207), and the process proceeds to S208. .

  The guidance display is a display that prompts the user to enable the ADF high-speed mode, and is, for example, a display that emphasizes the presence of the setting item of the ADF high-speed mode. As an example of the guidance display, a blinking display of a character string indicating a setting item of the ADF high-speed mode, a change of the background color of the character string, a change of the character color of the character string, and an effective setting of the ADF high-speed mode For example, a check box or a button for performing a display is displayed in a specific form, a popup including a message indicating that the setting of the ADF high-speed mode is confirmed, and the like are exemplified.

  When the CPU 11 denies the determination of S203 (S203: No), or when the CPU 11 determines in S205 that the ADF high-speed mode is set to be valid (S205: Yes), the CPU 11 determines that the application 14b On the other hand, before outputting the scan execution instruction to the scanner 30, it is determined whether or not the driver UI is set to be displayed (S218). If the CPU 11 determines that the setting is made for the application 14b (S218: Yes), the CPU 11 displays the driver UI on the LCD 18 (S219), and the process proceeds to S208.

  According to the processing of S203 to S207, S218, and S219, when the document width of the document to be read is a length corresponding to the long side of the A4 size, there is a possibility that the portrait A3 size is placed. Or the driver UI is displayed on condition that the ADF high-speed mode is disabled.

  If the document width of the document to be read is a length corresponding to the long side of the A4 size, the ADF high-speed mode may have been intended. However, in such a case, if the ADF high-speed mode is disabled, the original reading process is performed without reflecting the intention. On the other hand, if the document width of the document to be read is a length corresponding to the long side of the A4 size and there is a possibility that a portrait A3 size is placed, the document to be read is There is a case where it is A3 size in the direction and a case where it is placed in A4 size in the horizontal direction but is erroneously detected as A3 size in the vertical direction because the placement position is shifted. is assumed. In the former case, it is not preferable that the setting of the ADF high-speed mode is effective. In the latter case, if the ADF high-speed mode is not set to be effective, even if the ADF high-speed mode is intended, the original reading process is performed without reflecting the intention.

  With respect to such a problem, according to the present embodiment, since the driver UI is displayed in each of the above situations, the ADF high-speed mode can be appropriately set according to the original intention through the driver UI. In particular, according to the present embodiment, in each of the above situations, guidance display to the setting items of the ADF high-speed mode is performed, so that the ADF high-speed mode can be appropriately set according to the orientation of the document to be read.

  After the process of S207 or S219, the CPU 11 waits for an instruction indicating the completion of setting to be input to the driver UI (S208: No). When the CPU 11 receives an input of an instruction indicating the completion of setting (S208: Yes), the CPU 11 determines whether or not the ADF high-speed mode is set to be valid (S209) as in S205. The CPU 11 receives setting values for each setting such as the setting of the ADF high-speed mode in response to receiving the input of the instruction indicating the completion of the setting.

  When the CPU 11 determines that the ADF high-speed mode is set to be invalid (S209: No), the CPU 11 displays a normal setting user interface (hereinafter, “normal setting UI”) on the LCD 18 (S220), and the process is performed in S213. Migrate to The normal setting UI is a user interface for setting scan settings, for example, document size and resolution. A scan setting that has not been changed in the driver UI can be changed via the normal setting UI. In addition, when CPU11 denies determination of S209, CPU11 is good also as a structure which abbreviate | omits the process of S220 and transfers a process to S213.

  On the other hand, when the CPU 11 determines that the ADF high-speed mode is set to be effective (S209: Yes), the CPU 11 displays a wizard-type dialog on the LCD 18 for performing settings specific to the ADF high-speed mode ( S210). In the present embodiment, the rotation direction of the read image and the document size are exemplified as settings specific to the ADF high-speed mode.

  Specifically, either the clockwise direction or the counterclockwise direction can be selected as the rotation direction of the read image. When a document drawn with the portrait orientation is read with the ADF high-speed mode enabled, if the rotation direction of the read image is not appropriate, the read image with the originally intended top and bottom reversed. Will be obtained. In the present embodiment, since the rotation direction of the read image can be selected by a wizard-type dialog, the above problem can be avoided. As the document size, either A4 size or letter size can be selected. Therefore, since the read image data acquired from the scanner 30 can be cut out in a size corresponding to the original document size intended from the beginning, it is possible to prevent the contents of the original from being cut out.

  The CPU 11 accepts the selection of the rotation direction of the read image and the selection of the document size (S211 and S212), and the process proceeds to S213. On the other hand, if the CPU 11 determines in S218 that the setting for displaying the driver UI is not made (S218: No), the CPU 11 shifts the processing to S213. If the ADF high-speed mode has already been set to be valid when the CPU 11 makes the determination in S205, it is highly likely that settings specific to the ADF high-speed mode have already been made. Therefore, in such a case, since the display of the wizard-type dialog is omitted, the ADF high-speed mode can be suitably used.

  In step S <b> 213, the CPU 11 determines whether a document is placed on the paper feed tray. The CPU 11 makes the determination in S213 based on the placement information acquired by inquiring of the scanner 30. Specifically, when the obtained placement information indicates that a document is placed on the paper feed tray, the CPU 11 affirms the determination in S213. On the other hand, if the obtained placement information indicates that no document is placed on the paper feed tray, the CPU 11 denies the determination in S213.

  When the CPU 11 denies the determination in S213 (S213: No), the CPU 11 executes an error process including a message indicating that no document is placed on the paper feed tray (S221), and performs this process. finish. On the other hand, when the CPU 11 affirms the determination in S213 (S213: Yes), the CPU 11 outputs a scan execution instruction to the scanner 30 (S214). Therefore, it is possible to prevent the scan execution instruction from being output to the scanner 30 in a state where the document to be read is not placed on the paper feed tray.

  After the process of S214, the CPU 11 waits to acquire read image data from the scanner 30 (S215: No). When the CPU 11 determines that the read image data has been acquired (S215: Yes), the CPU 11 determines whether or not the ADF high-speed mode is set to be effective (S216), as in S205. When the CPU 11 determines that the ADF high-speed mode is set to be effective (S216: Yes), the CPU 11 performs an image corresponding to the rotation direction and the document size received in S211 and S212 on the acquired read image data. Processing is performed (S217), the processed image data is transferred to the application 14b, and this processing ends. On the other hand, when the CPU 11 determines that the ADF high-speed mode is disabled (S216: No), the CPU 11 skips the process of S217, passes the acquired read image data to the application 14b, and performs this process. finish.

  According to the first embodiment, if the document width of the document to be read is a length corresponding to the long side of the A4 size, a wizard-type dialog can be displayed. Therefore, settings specific to the ADF high-speed mode can be performed via the wizard. Thus, even when the scanner 30 reads the document using the ADF high-speed mode, that is, when the document in which the content is described with the longitudinal direction as the top is read in the document direction with the short direction as the top. The PC 10 can obtain an image according to the original intention. In particular, when the document width of the document to be read is a length corresponding to the long side of the A4 size and the ADF high-speed mode is enabled, a wizard-type dialog is displayed. There is no discrepancy with the intention to set the mode.

  On the other hand, if the document width of the document to be read is not the length corresponding to the long side of the A4 size, the wizard-type dialog is not displayed unless the ADF high-speed mode is enabled via the driver UI. Therefore, it is possible to avoid making a setting specific to the ADF high-speed mode for a document of a size not applicable to the ADF high-speed mode.

  Further, according to the first embodiment, when the document width of the document to be read is a length corresponding to the long side of the A4 size, and there is no possibility that the A3 size in the vertical direction is placed. That is, when a document suitable for use in the ADF high-speed mode is placed on the paper feed tray, the driver UI is displayed unless the ADF high-speed mode is set to be valid. Thus, the ADF high-speed mode can be set to be effective. Therefore, also in this respect, even when the scanner 30 reads a document using the ADF high-speed mode, the PC 10 can obtain an image according to the original intention. In particular, since the guidance display to the setting items of the ADF high-speed mode is performed, the ADF high-speed mode can be used more suitably.

  Next, a second embodiment will be described with reference to FIG. In the second embodiment, the same parts as those in the first embodiment described above are denoted by the same reference numerals, and the description thereof is omitted. FIG. 3 is a flowchart illustrating the scan processing according to the second embodiment. Each process shown in the flowchart of FIG. 3 is a process executed by the CPU 11 according to the scanner driver 14a of the second embodiment. Hereinafter, the main differences from the scan processing of the first embodiment will be mainly described.

  First, in the first embodiment, when a document suitable for using the ADF high-speed mode is placed on the paper feed tray, if the ADF high-speed mode is not set to be valid, the driver UI is displayed and the ADF is displayed. The high-speed mode is activated as necessary. Instead, in the second embodiment, when a document suitable for using the ADF high-speed mode is placed on the paper feed tray and the ADF high-speed mode is not set to be effective, the ADF high-speed mode is automatically set. Enable it.

Specifically, when the CPU 11 affirms the determination of S203 and denies the determination of S204 (S203: Yes, S204: No),
When the CPU 11 determines that the ADF high-speed mode is set to be valid (S205: Yes), the CPU 11 sets the ADF high-speed mode to be valid (S301), and the process proceeds to S210. On the other hand, when the CPU 11 determines that the ADF high-speed mode is disabled (S205: No), the CPU 11 skips the process of S301 and shifts the process to S210.

  According to the processing in S301, when a document suitable for use in the ADF high-speed mode is placed on the paper feed tray, the mode is automatically selected even if the ADF high-speed mode is set to invalid. Enabled. Accordingly, since a complicated operation for enabling the ADF high-speed mode via the driver UI is not necessary, the reading process as originally intended can be easily performed.

  Secondly, in the first embodiment, the PC 10 performs image processing on the acquired read image data according to the rotation direction and document size received in S211 and S212. Instead, in the second embodiment, the scanner 30 is caused to execute image processing on the read image data.

  Specifically, after the process of S214, the CPU 11 outputs an instruction regarding image processing to the scanner 30 (S302), and the process proceeds to S302. In S <b> 302, when the ADF high-speed mode is set to be valid, the CPU 11 outputs an instruction to the scanner 30 to execute image processing according to the rotation direction and document size received in S <b> 211 and S <b> 212. On the other hand, when the ADF high-speed mode is disabled, the CPU 11 outputs an instruction indicating that image processing is not performed to the scanner 30.

  According to the processing of S302, when the ADF high-speed mode is set to be valid, the scanner 30 generates read image data subjected to the instructed image processing while reading the document. Therefore, the PC 10 can acquire read image data that has already undergone image processing according to the rotation direction and document size received in S211 and S212 from the scanner 30, and thus the PC 10 needs to perform the image processing. Absent.

  Next, a third embodiment will be described with reference to FIG. In the first embodiment described above, a setting specific to the ADF high-speed mode is performed using a wizard-type dialog before outputting a scan execution instruction to the scanner 30. Instead, in the third embodiment, after a scan execution instruction is output to the scanner 30, settings specific to the ADF high-speed mode are performed.

  FIG. 4 is a flowchart illustrating the scan processing according to the third embodiment. Each process shown in the flowchart of FIG. 4 is a process executed by the CPU 11 according to the scanner driver 14a of the third embodiment. Hereinafter, the main differences from the scan processing of the first embodiment will be mainly described. Note that in the third embodiment, identical symbols are assigned to parts identical to those in the first embodiment described above and descriptions thereof are omitted.

  If the document is placed on the paper feed tray after the process of S201 (S213: Yes), the CPU 11 outputs a scan execution instruction to the scanner 30 (S214). After the process of S214, the CPU 11 acquires document width information (S202), and makes a determination of S203 based on the acquired document width information. When the CPU 11 affirms the determination of S203 (S203: Yes), the CPU 11 performs the determination of S205.

  When the CPU 11 affirms the determination in S205 (S205: Yes), it is determined whether or not the document to be read may be a vertically oriented A3 size document (S401). That is, in this embodiment, when the CPU 11 determines that the document width of the document to be read is a width corresponding to the long side of the A4 size and the ADF high-speed mode is set to be valid, the CPU 11 Then, it is determined whether there is a possibility that the document to be read is a portrait-oriented A3 size document.

  In the present embodiment, the CPU 11 determines the determination in S401 based on the elapsed time after outputting the scan execution instruction. That is, a time defined in advance as the time required for conveying the short side corresponding to the length of the A4 size document, for example, an elapsed time since the scan execution instruction is output with a threshold of 5 seconds. When the threshold value is exceeded, the CPU 11 affirms the determination in S401. On the other hand, if the elapsed time after outputting the scan execution instruction does not exceed the threshold value, the CPU 11 denies the determination in S401.

  Alternatively, the CPU 11 may acquire the rotation number of the conveyance roller for conveying the document from the scanner 30 and perform the determination in S401 based on the acquired rotation number. In such a case, the number of rotations required to convey the length of the short side of the A4 size document is set as a threshold value. Examples of the method for acquiring the rotation number of the conveyance roller from the scanner 30 include a method in which the CPU 11 inquires the scanner 30 every predetermined time and a method in which the rotation number periodically transmitted from the scanner 30 is acquired. Further, similarly to the first embodiment, the CPU 11 may be configured to make the determination in S401 based on the A3 size information.

  When the CPU 11 denies the determination in S401 (S401: No), this is because the document suitable for using the ADF high-speed mode is placed on the paper feed tray and the ADF high-speed mode is set to be valid. It shows that. Therefore, in such a case, the CPU 11 shifts the processing to S210 and displays a wizard-type dialog on the LCD 18 for performing settings specific to the ADF high-speed mode. On the other hand, when the CPU 11 denies the determination of S203 (S203: No), or when the CPU 11 denies the determination of S205 (S205: No), there was an intention to set the ADF high-speed mode to be valid. Since the possibility is low, in such a case, the CPU 11 shifts the processing to S215 without performing settings specific to the ADF high-speed mode.

  On the other hand, when the CPU 11 affirms the determination in S401 (S401: Yes), the CPU 11 displays the driver UI on the LCD 18 (S206), and displays a guidance display for canceling (that is, invalidating) the ADF high-speed mode. (S402), and the process proceeds to S208. The guidance display is a display that prompts the user to invalidate the ADF high-speed mode. For example, the guidance display emphasizes the presence of the setting item of the ADF high-speed mode, similar to the guidance display in S207 described above. The guidance display for releasing the ADF high-speed mode may be displayed in a manner different from the guidance display in S207, that is, the guidance display for setting the ADF high-speed mode.

  According to the third embodiment, document width information is acquired after outputting a scan execution instruction to the scanner 30, and the determination in S203 is performed based on the acquired document width information. Even in this case, an image in accordance with the original intention can be obtained from the document image data read using the ADF high-speed mode.

  Even when the ADF high-speed mode is set to be effective, a guidance display for setting the ADF high-speed mode is displayed when there is a possibility that the document to be read is a portrait-oriented A3 size document. Since it is displayed, the ADF high-speed mode can be canceled via the driver UI as necessary. Therefore, the ADF high-speed mode can be appropriately set according to the orientation of the document to be read.

  Next, a fourth embodiment will be described with reference to FIG. In the third embodiment described above, the PC 10 is configured to perform image processing according to the rotation direction and document size received in S211 and S212 on the acquired read image data. Instead, in the fourth embodiment, the scanner 30 is caused to execute image processing on the read image data.

  FIG. 5 is a flowchart showing the scan processing of the fourth embodiment. Each process shown in the flowchart of FIG. 5 is a process executed by the CPU 11 according to the scanner driver 14a of the fourth embodiment. Hereinafter, the main differences from the scan processing of the third embodiment will be mainly described. Note that in the fourth embodiment, identical symbols are assigned to parts identical to those in the third embodiment described above, and a description thereof is omitted.

  After the process of S212, the CPU 11 outputs an instruction regarding image processing to the scanner 30 (S501), and the process proceeds to S215. The CPU 11 performs the process of S501 in the same manner as S302 of the second embodiment. When an instruction relating to image processing is output to the scanner 30, the scanner 30 performs the instructed image processing while reading the original with respect to the original read after the original being read at the timing when the instruction is received. The read image data is generated.

  Therefore, the PC 10 can acquire read image data that has been subjected to the instructed image processing for an original that is read after the original being read at the timing when the scanner 30 receives the instruction output in S501. it can. On the other hand, the PC 10 acquires unprocessed read image data for a document that is being read at the timing when the scanner 30 receives the instruction output in S501 or a document that has been read before that time.

  Therefore, in this embodiment, when the CPU 11 determines that the ADF high-speed mode is enabled after acquiring the read image data from the scanner 30 (S216: Yes), the CPU 11 is performing image processing. The image processing corresponding to the rotation direction and the document size received in S211 and S212 is performed on a non-existing page (S502).

  In step S <b> 502, the CPU 11 determines whether the page has not been subjected to image processing, for example, the page number of the document being read at the timing of receiving the instruction output in step S <b> 501 acquired from the scanner 30. Based on. Alternatively, the CPU 11 may detect the size of the read image data acquired from the scanner 30 and determine that the read image data corresponding to the document in landscape orientation is a page that has not been subjected to image processing.

  According to the fourth embodiment, even after the scanner 30 starts reading a document and receives an instruction for image processing from the PC 10, even if the PC 10 acquires some read image data in an unprocessed state. Since the CPU 11 executes the processing of S502, it is possible to perform image processing according to the settings set in the wizard-type dialog displayed in S210 for all the originals.

  Next, a fifth embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing the scan processing of the fifth embodiment. Each process shown in the flowchart of FIG. 6 is a process executed by the CPU 11 according to the scanner driver 14a of the fifth embodiment. Hereinafter, the main difference from the scan processing of the fourth embodiment will be mainly described. Note that in the fifth embodiment, identical symbols are assigned to parts identical to those in the fourth embodiment described above and descriptions thereof are omitted.

  In the present embodiment, settings specific to the ADF high-speed mode are performed on the condition that the acquisition of the read image data is started after the scan execution instruction is output to the scanner 30. Specifically, after the process of S214, the CPU 11 stands by until acquisition of read image data from the scanner 30 is started (S601: No). When acquisition of the read image data is started (S601: Yes), the CPU 11 proceeds to S203.

  After the process of S501, the CPU 11 waits until acquisition of the read image data from the scanner 30 is completed (S602: No). When the acquisition of the read image data is completed (S602: Yes), the CPU 11 shifts the process to S216. In the present embodiment, when the CPU 11 affirms the determination of S216, the process of S502 is executed.

  According to the fifth embodiment, S502 is performed on the read image data corresponding to the document being read at the timing when the scanner 30 receives the instruction output in S501 and the read image data already acquired from the scanner 30. The image processing can be performed at. Therefore, it is possible to perform image processing according to the settings set in the wizard-type dialog displayed in S210 for all the originals.

  Next, a sixth embodiment will be described with reference to FIG. FIG. 7 is a flowchart showing the scan processing of the sixth embodiment. Each process shown in the flowchart of FIG. 7 is a process executed by the CPU 11 according to the scanner driver 14a of the sixth embodiment. Hereinafter, the main differences from the scan processing of the first embodiment will be mainly described. Note that in the sixth embodiment, identical symbols are assigned to parts identical to those in the first embodiment described above and descriptions thereof are omitted.

  In this embodiment, when a document suitable for using the ADF high-speed mode is placed on the paper feed tray and the ADF high-speed mode is set to be effective, the ADF high-speed is not displayed without displaying the driver UI. Displays a wizard-style dialog for setting mode-specific settings. Specifically, when the CPU 11 affirms the determination in S205 (S205: Yes), the CPU 11 proceeds to S210.

  According to the sixth embodiment, if the document width of the document to be read is a length corresponding to the long side of the A4 size, the display of the driver UI is omitted regardless of the setting for the application 14b. The operation for reading a document can be simplified using the ADF high-speed mode.

  Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above embodiment, the scanner driver 14a is exemplified as the information processing program of the present invention. That is, each process shown in each flowchart of FIGS. 2 to 7 has been described as being executed by the CPU 11 in accordance with the scanner driver 14a. It is good also as a structure which makes CPU11 perform each of these processes according to the application 14b. In such a case, the application 14b is an information processing program of the present invention. Alternatively, a configuration in which the scanner driver 14a and the application 14b cooperate or a program in which the scanner driver 14a and the application 14b are integrated causes the CPU 11 to execute each process illustrated in the flowcharts of FIGS. Also good.

  In the above embodiment, the PC 10 is exemplified as the information processing apparatus on which the information processing program of the present invention is mounted. However, the information processing apparatus can be connected to a display unit such as an LCD capable of displaying information and an image reading unit such as the scanner 30. If it is an apparatus, various apparatuses, such as a smart phone, a mobile telephone, PDA, a tablet terminal, are applicable as an information processing apparatus.

  In the above embodiment, the PC 10 on which the scanner driver 14a is mounted is configured to cause the scanner 30 which is an image reading unit separate from the PC 10 to execute a document reading process. It may be configured to incorporate. In the above embodiment, the input device 17 and the LCD 18 are integrated with the PC 10 that is the information processing device. However, the input device 17 and the LCD 18 are connected to the PC 10 separately from the PC 10. There may be.

  In the above-described embodiment, the scanner 30 is exemplified as the image reading unit. However, the image reading unit is another device that can generate image data based on reading of an original, for example, a multifunction peripheral device having a plurality of functions including a scanner function. In addition, the present invention can be applied as an image reading unit.

  In the above embodiment, the PC 10 is configured to be loaded with the information processing program of the present invention, but the scanner 30 may be configured to be loaded with the information processing program of the present invention. In such a modified example, when a scan execution instruction is input via the user interface of the application 14b, the CPU 11 outputs an instruction to the scanner 30, and the control unit 31 performs the processes illustrated in the flowcharts of FIGS. What is necessary is just to comprise so that each process shown may be performed. The scanner 30 in this modification is an example of the “image reading apparatus” in the present invention.

  In the above embodiment, the PC 10 on which the scanner driver 14a is mounted is configured to directly issue a reading instruction to the scanner 30 on the LAN 50. Instead, the present invention can be applied to a configuration in which the scanner 30 is operated from the PC 10 by using a service (so-called “cloud service”) provided by the server 200 on the Internet 800. Specifically, for example, when a scan execution instruction is input via the user interface of the application 14b, the CPU 11 outputs an instruction to the server 200, and the control unit of the server 200 performs the processing illustrated in FIGS. It is good also as a structure which performs each process shown to this flowchart. A system including the PC 10, the server 200, and the scanner 30 in this modification is an example of the “image reading system” of the present invention.

  In the above embodiment, the threshold value for the determination in S203 is the width corresponding to the long side of the A4 size, but an appropriate value can be adopted as the threshold value if the length is longer than the short side of the A4 size. Therefore, an appropriate length longer than the short side of the A4 size, which is the threshold value for the determination in S203, corresponds to the “first length” in the claims.

  In the above embodiment, the A4 size is exemplified as the size of the document to which the ADF high-speed mode can be applied. However, the size is not limited to this and may be a letter size. In such a case, the letter size is an example of “first predetermined size”.

  In the above-described embodiment, the document size and the read image data size are assumed to be equal. However, the read image data size is, for example, about 2 mm larger or smaller than the document size. The present invention is applicable even when the PC 10 that has acquired the image data enlarges, reduces, or trims the read image data according to the size of the document.

  In the above embodiment, the determination in S204 is performed using the A3 size information based on the detection by the A3 size sensor 36. However, a configuration in which a failure of the A3 size sensor 36 is considered may be employed. Specifically, for example, it is configured so that the failure of the A3 size sensor 36 can be registered in the application 14b, and when the failure of the A3 size sensor 36 is registered, the CPU 11 affirms the determination of S204. May be.

  In the above-described embodiment, the configuration is such that either the clockwise direction or the counterclockwise direction can be selected as the rotation direction of the read image via the wizard-type dialog displayed in S210. When the CPU 11 affirms the determination of S204 or S401, but the CPU 11 executes the process of S210 because the ADF high-speed mode is set to be valid, “not rotate” is selected as an option for the rotation direction of the read image in the dialog. May be provided. The document width is a width corresponding to the long side of the A4 size, but when a document having a length slightly longer than the short side of the A4 size is set on the paper feed tray, the option of “does not rotate” By providing this, the read image data for the document can be processed without rotating.

  Among the processes shown in FIGS. 2 to 7, some of the processes may be omitted or changed without departing from the independent claims. For example, it is good also as a structure which performs the process of S218, S219, S208, and S209 in FIG. 3 between S205 and S301. In such a modified example, after the driver UI is displayed in S219, it is preferable to display the process of S207, that is, the guidance display for setting the ADF high-speed mode.

  It is good also as a structure which performs the process of S206, S208, and S209 in FIGS. 4-6 between S401 and S210. In such a modification, it is preferable to execute the process of S207 after the driver UI is displayed in S206.

  In FIG. 2 to FIG. 7, the CPU 11 is configured to execute the process of determining whether or not the vertically oriented A3 size is placed, that is, S204 or S401. However, the process may be omitted. In FIG. 7, the CPU 11 is configured to shift the process to S210 when the determination in S205 is affirmed. However, in such a case, the CPU 11 may be configured to shift the process to S213.

  2 and 7, after the driver UI is displayed in 206, the processing of S207, that is, the guidance display for setting the ADF high-speed mode is displayed. However, the processing of S207 is omitted. Also good. Further, the process of S402 in FIGS. 4 to 6 may be omitted. 4 to 6, the processing order of S214 and S202 may be reversed.

  In the above-described embodiment, the CPU 11 has been described as a configuration for executing each process described in FIGS. 2 to 7. However, each of the processes described in each of these drawings is configured to be executed jointly by a plurality of CPUs. Also good. Further, an IC such as an ASIC may be configured to execute each process described in each of the above drawings independently or in cooperation with a plurality of ICs. Further, the CPU 11 and an IC such as an ASIC may cooperate to execute each process described in the above drawings. Moreover, it is good also as a structure implemented combining each characteristic demonstrated by the said embodiment and each modification mentioned above suitably.
