  Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Mechanical configuration>
An image reading apparatus 1 shown in FIG. 1 is a scanner that reads an image by an ADF (Auto Document Feeder) method. The image reading apparatus 1 includes a housing 11 and a tray 12 (an example of a document table).

  The housing 11 forms an outer shell of the image reading apparatus 1. In a state in which the image reading apparatus 1 is installed on the horizontal plane, the first side surface 13 of the housing 11 rises substantially perpendicular to the horizontal plane, and is opposed to the first side surface 13 with a space therebetween. Is inclined away from the first side surface 13 toward the upper side. The height of the second side surface 14 is lower than the height of the first side surface 13, and the upper surface 15 extending from the upper end of the second side surface 14 toward the upper end of the first side surface 13 is closer to the upper side as it is closer to the first side surface 13. Inclined to be located.

  Note that the front and rear directions and the left and right directions used in the following description are directions defined based on a state in which the image reading apparatus 1 is viewed from the second side face 14 side.

  A gap is provided between the upper end edge of the first side surface 13 and the rear end edge of the upper surface 15, and the tray 12 extends obliquely from the gap to the rear upper side. The tray 12 is configured to be able to support a plurality of sheet-like documents S in a stacked state in which they are stacked.

  Between the upper end edge of the first side surface 13 and the tray 12 is an insertion port 16 into which the document S supported by the tray 12 is inserted. The second side surface 14 is formed with a discharge port 17 for discharging the document S out of the housing 11. In the housing 11, a document conveyance path 18 that is inclined forward and downward from the insertion port 16 toward the discharge port 17 is provided.

  The image reading apparatus 1 includes a feed roller 21 (an example of a conveyance unit), a reverse roller 22 (an example of a conveyance unit), a conveyance roller pair 23 (an example of a conveyance unit), and a discharge roller pair 24 (an example of a conveyance unit). Yes.

  The feed roller 21, the reverse roller 22, the transport roller pair 23, and the discharge roller pair 24 are provided so as to be rotatable around a rotation axis extending in the left-right direction. The feed roller 21 and the reverse roller 22 are disposed downstream of the lower end portion of the tray 12 in the document conveyance path 18. The insertion port 16 defines the upstream end of the document conveyance path 18, and the discharge port 17 defines the downstream end of the document conveyance path 18. The circumferential surface of the reverse roller 22 is in contact with the circumferential surface of the feed roller 21 from the front upper side. The conveyance roller pair 23 is disposed downstream of the feed roller 21 and the reverse roller 22 in the document conveyance path 18. The discharge roller pair 24 is disposed at a position behind the discharge port 17 with a gap from the conveyance roller pair 23.

  In the document conveyance path 18, a first image reading unit 31 and a second image reading unit 32 that read an image of the document S are provided between the conveyance roller pair 23 and the discharge roller pair 24.

  The first image reading unit 31 is disposed below the document conveyance path 18 with the document reading surface 33 facing the document conveyance path 18. As shown in FIG. 2, the first image reading unit 31 includes a CIS (Contact Image Sensor) 34, an AFE (Analog Front End) 35, and the like. In the first image reading unit 31, the image on the lower surface of the document S facing the document reading surface 33 is read by the CIS 34. The analog image signal output from the CIS 34 is converted into digital image data by the AFE 35 and output to the control unit 55. Thereby, reading of an image by the first image reading unit 31 is achieved.

  The second image reading unit 32 is shifted to the upper side of the document conveyance path 18 to the front side (downstream in the conveyance direction of the document S) with respect to the first image reading unit 31, and the document reading surface 36 is moved to the document conveyance path. It is arranged in a state facing the 18 side. The second image reading unit 32 includes a CIS 37, an AFE 38, and the like. In the second image reading unit 32, the image on the upper surface of the document S facing the document reading surface 36 is read by the CIS 37. The analog image signal output from the CIS 37 is converted into digital image data by the AFE 38 and output to the control unit 55. Thereby, reading of an image by the second image reading unit 32 is achieved.

  Further, as shown in FIG. 1, the image reading apparatus 1 includes a document sensor 41 that detects the document S supported on the tray 12. The document sensor 41 may be composed of, for example, a rotation member that is rotatably held in response to contact with the document S, and an optical sensor that detects the rotation of the rotation member. The optical sensor includes a light emitting unit and a light receiving unit, detects whether or not the light emitted from the light emitting unit is received by the light receiving unit, and outputs a signal indicating the detection result to the control unit 55. For example, when the document S is not in contact with the rotating member, the rotating member blocks light emitted from the light emitting unit, and the light receiving unit does not detect the light. On the other hand, when the document S is in contact with the rotating member, the light emitted from the light emitting unit is not blocked by the rotation of the rotating member, and the light receiving unit detects the light. However, it may be detected whether or not the document S blocks light by causing the light emitting unit and the light receiving unit to face each other with the document transport path 18 interposed therebetween. In this case, the rotating member becomes unnecessary.

<Reading operation>
When reading an image of the document S, the document S is placed on the tray 12.

  The document S supported by the tray 12 is inserted into the insertion slot 16 until the leading end comes into contact with the feed roller 21 and the reverse roller 22. When the document S is inserted to that position, the document sensor 41 outputs a detection signal (ON signal) indicating that the document S has been detected.

  At the start of reading an image of a document, torque is applied to the feed roller 21 and the reverse roller 22 by a first motor 51 and a second motor 52, which will be described later, in a counterclockwise direction when viewed from the right side. This torque causes the feed roller 21 to rotate counterclockwise, so that a conveying force is applied from the feed roller 21 to the lowermost document S of the documents S supported by the tray 12, so that the lowermost document S It is drawn between the feed roller 21 and the reverse roller 22. The reverse roller 22 is transmitted with driving force from the second motor 52 via a torque limiter (not shown). The idling torque of the torque limiter is set to a value that causes idling by the frictional force between the document S and the reverse roller 22 and the frictional force between the feed roller 21 and the reverse roller 22. On the other hand, the idling torque of the torque limiter is set to a value that does not cause idling due to the frictional force between the documents S. For this reason, when there is no document S between the feed roller 21 and the reverse roller 22, or when only one document S exists between the feed roller 21 and the reverse roller 22, the reverse roller 22 It rotates clockwise against the driving force from the motor 52. On the other hand, when there are two or more documents S between the feed roller 21 and the reverse roller 22, the reverse roller 22 rotates counterclockwise according to the driving force from the second motor 52. Therefore, the lowermost document S that has been pulled in is separated from the document S above it, and one document S passes between the feed roller 21 and the reverse roller 22 and is fed into the document transport path 18.

  Further, the lower roller of the transport roller pair 23 and the lower roller of the discharge roller pair 24 are rotated counterclockwise, and the upper rollers thereof are driven to rotate by the lower rollers. The document S sent to the document transport path 18 receives transport force from the transport roller pair 23 and the discharge roller pair 24, is transported downstream in the document transport path 18, and is discharged out of the housing 11 from the discharge port 17. Is done.

  While the document S is being transported through the document transport path 18, when the lower surface of the document S faces the document reading surface 33 of the first image reading unit 31, the image on the lower surface is read as the first image. Read by the unit 31. When the upper surface of the document S faces the document reading surface 36 of the second image reading unit 32, the image on the upper surface is read by the second image reading unit 32.

<Electrical configuration>
As shown in FIG. 2, the image reading apparatus 1 includes a first motor 51 that is a drive source of the feed roller 21, and a second motor 52 that is a drive source of the reverse roller 22, the transport roller pair 23, and the discharge roller pair 24. And. The first motor 51 and the second motor 52 are, for example, stepping motors.

  The image reading apparatus 1 may be provided with a single motor as a common drive source for the feed roller 21, the reverse roller 22, the transport roller pair 23, and the discharge roller pair 24.

  The image reading apparatus 1 also includes a network interface (I / F) 53, a USB (Universal Serial Bus) interface (I / F) 54, and a control unit 55.

  The network interface 53 is an interface for data communication with an external device such as a PC (Personal Computer) via a LAN (Local Area Network). The communication method may be a wireless communication method or a wired communication method.

  The USB interface 54 is an interface for data communication with a USB device. The USB interface 54 is provided with a port for connecting a USB device. The image reading device 1 may perform data communication with an external device via the USB interface 54.

  The control unit 55 includes a CPU 56 (an example of a control unit), a ROM 57, and a RAM 58 (an example of a storage unit). A document sensor 41 is connected to the control unit 55, and a detection signal from the document sensor 41 is input. Further, the first image reading unit 31, the second image reading unit 32, the first motor 51, the second motor 52, the network interface 53, and the USB interface 54 are connected to the control unit 55.

  The CPU 56 executes a program stored in the ROM 57 based on a signal or the like input to the control unit 55, whereby the first image reading unit 31, the second image reading unit 32, the first motor 51, the second Each unit such as the motor 52, the network interface 53, and the USB interface 54 is controlled, and data is received from the first image reading unit 31, the second image reading unit 32, the network interface 53, the USB interface 54, and the like. When the control (program) is executed by the CPU 56, the RAM 58 is used as a work area. The RAM 58 may include a non-volatile memory such as NVRAM (Non Volatile RAM).

<Registration process>
The image reading apparatus 1 can execute a document bundle reading job that reads images of a plurality of document bundles by switching scan settings for each document bundle. In order to execute this document bundle reading job, it is necessary to pre-register scan settings.

  The process shown in FIG. 3 is a registration process for registering scan settings. The registration destination (save destination) of the scan setting is the RAM 58 of the control unit 55, but the scan setting is stored in the nonvolatile memory included in the RAM 58 so that the registered data is not lost even when the power of the image reading apparatus 1 is turned off. Or protected by battery backup. Alternatively, when the ROM 57 includes an EEPROM, the scan setting may be registered in the EEPROM of the ROM 57.

  The scan setting is a setting related to image reading by the first image reading unit 31 and the second image reading unit 32. The contents of the setting include, for example, reading resolution, reading mode, document size, and confirmation information as shown in FIG. The reading mode is one of a color mode suitable for reading a color image and a monochrome mode suitable for reading a monochrome image. The confirmation information is information indicating whether or not confirmation of using the scan setting is necessary. The scan setting includes a workflow, that is, a scan setting switching pattern.

  Registration of scan settings can be performed, for example, by the user operating an external device connected to the network interface 53 or the USB interface 54. That is, by the operation of the external device, the contents of the scan setting, the workflow number for specifying the workflow in which the scan setting is used, and the order (usage order) in which the scan setting is used in the workflow are input. When the transmission of the input content is instructed, the input content is transmitted from the external device to the image reading apparatus 1. Further, when the image reading apparatus 1 is provided with an operation unit having various operation keys and a display unit such as a liquid crystal display, the scan setting may be registered by an input to the operation unit. Note that the operation unit may be a touch key provided integrally with the display unit.

  When the CPU 56 receives scan settings from an external device connected to the network interface 53 or the USB interface 54, the CPU 56 starts the registration process shown in FIG. The CPU 56 registers the received scan setting in a nonvolatile memory included in the RAM 58 (S11).

  When one scan setting is registered in the nonvolatile memory, the CPU 56 determines whether the next scan setting has been received (S12). When the next scan setting is received within a predetermined time from the reception of the previous scan setting, it is determined that there is a next registration of the scan setting (S12: YES), and the received scan setting is registered in the nonvolatile memory. .

  On the other hand, when the next scan setting is not received, the CPU 56 determines that there is no next registration of the next scan setting (S12: NO), and ends the registration process.

  Through this registration process, the workflow is registered in the RAM 58 together with the scan setting contents. In the example shown in FIG. 4, when “setting 1”, “setting 2”, and “setting 3” are used in this order in the workflow specified by the workflow number “1”, the resolution “ “600 dpi”, reading mode “color mode”, and document size “A4”, as well as the workflow number “1” and the order of use “1” in that workflow, are set in the nonvolatile memory. . As for “setting 2”, the workflow number “1” and the order of use “2” in the workflow are set together with the settings of the resolution “300 dpi”, the reading mode “monochrome mode” and the document size “A4”. The contents are registered in the nonvolatile memory. As for “setting 3”, the workflow number “1” and the order of use “3” in the workflow are set together with the settings of the resolution “300 dpi”, the reading mode “color mode”, and the document size “A4”. The contents are registered in the nonvolatile memory.

<Document bundle reading process>
In order to execute the document bundle reading job, the CPU 56 executes the document bundle reading process shown in FIGS. 5A and 5B. The document bundle reading process is started in response to the power supply of the image reading apparatus 1 being turned on.

  The execution of the document bundle reading job is instructed to the image reading apparatus 1 from an external device connected to the network interface 53, for example. That is, by operating the external device, the workflow number corresponding to the workflow of the document bundle reading job and the start of reading related to the document bundle reading job (start of execution of the document bundle reading job) are input, and the transmission of the input contents is instructed. Then, the input content is transmitted from the external device to the image reading device 1. In addition, when the image reading apparatus 1 is provided with an operation unit having various operation keys and a display unit such as a liquid crystal display, an instruction to start execution of a document bundle reading job is performed by an input to the operation unit. It may be broken. As described above, the operation unit may be a touch key provided integrally with the display unit.

  In the document bundle reading process, the CPU 56 receives a reading start instruction related to the document bundle reading job in a state where a detection signal indicating that the document S supported on the tray 12 is detected is input from the document sensor 41. Is determined (S21).

  When an instruction to start reading is received (S21: YES), the CPU 56 specifies a group of scan settings associated with the workflow number from the scan settings registered in the RAM 58. Then, the scan setting (first scan setting) in the usage order “1” is specified from the specified scan setting group (S22).

  Thereafter, the CPU 56 starts reading the image of the document S with the scan setting of the usage order “1” (S23).

  When the image of one page of the document S is read by at least one of the first image reading unit 31 and the second image reading unit 32 (hereinafter referred to as “image reading units 31, 32”), the CPU 56 of the document sensor 41. The detection signal is checked to determine whether or not the next document S is supported on the tray 12 (S24).

  When the next document S is supported on the tray 12 (S24: YES), the CPU 56 causes the image reading units 31 and 32 to read the image of the next document S (S23).

  When images of all the originals S supported on the tray 12 are read and a detection signal indicating that the original S is not supported on the tray 12 is output from the original sensor 41, the CPU 56 outputs the next original S. (S24: NO), it is determined whether the scan order currently used is the last scan setting in the scan setting group specified by the workflow number of the document bundle reading job (S24: NO). S25).

  If the scan setting currently in use is not the last scan setting (S25: NO), the CPU 56 determines whether or not the document S is supported on the tray 12 by addition (S26 in FIG. 5B).

  The document bundle reading process does not proceed until the document S is supported on the tray 12 by the user (S26: NO).

  When the document S is supported on the tray 12 by the user (S26: YES), the CPU 56 refers to the number of documents S (hereinafter referred to as “the number of read documents”) from which an image has been read by the currently used scan setting. ) Exceeds the maximum number of sheets that can be supported on the tray 12 (hereinafter referred to as “maximum number of ADF sheets”) (S27). The maximum number of ADF sheets is previously written in the ROM 57 before the image reading apparatus 1 is shipped from the factory.

  When the number of read documents does not exceed the maximum ADF stack number (S27: NO), the CPU 56 needs to confirm that the scan setting confirmation information in the next order of the scan settings currently in use uses the scan settings. Is determined (S28). For example, if the scan setting currently in use is the scan setting of the usage order “1”, whether the confirmation information of the scan setting of the usage order “2” indicates that it is necessary to confirm that the scan setting is used Determined.

  When the confirmation information on the scan setting in the next order indicates that it is not necessary to confirm that the scan setting is used (S28: NO), the CPU 56 reads the scan setting in the next order from the RAM 58 (S29), Reading of the image of the document S by the next order scan setting is started (S23 in FIG. 5A).

  On the other hand, when the confirmation information of the scan setting in the next order indicates that confirmation of using the scan setting is necessary (S28 in FIG. 5A: YES), the CPU 56 sets the scan setting in the next order to the default display. Set (S30).

  Then, the CPU 56 scans the scan setting selection screen in which the scan settings in the next order are displayed by default in the drop-down list (pull-down menu) for selecting the scan settings toward the external device that is the transmission source of the reading start instruction. Is transmitted on the display (S31).

In response to this instruction, a scan setting selection screen is displayed on the display of the external device. In the drop-down list, all the scan settings included in the scan setting group specified by the workflow number of the original bundle reading job are displayed. When one scan setting is selected from the drop-down list and the selection decision is input to the external apparatus, selection information indicating the selected scan setting is transmitted from the external apparatus to the image reading apparatus 1. Is done. When the image reading apparatus 1 receives this selection information, the CPU 56 reads the scan setting indicated by the selection information from the RAM 58 (S32). The CPU 56 starts reading the image of the document S based on the scan setting indicated by the selection information (S23 in FIG. 5A). The scan setting of the next order is displayed by default in the drop-down list, but the current scan setting may be selected, and reading of the image of the document S with the current scan setting may be continued.
When the image reading apparatus 1 is provided with an operation unit having various operation keys and a display unit such as a liquid crystal display, a display instruction for a scan setting selection screen is given by an input to the operation unit. Also good. As described above, the operation unit may be a touch key provided integrally with the display unit.

  When the number of read documents exceeds the maximum ADF stack number (S27: YES), the CPU 56 does not display any scan setting in the drop-down list for selecting the scan setting, or the current scan setting is An instruction to display the displayed scan setting selection screen on the display is transmitted (S31).

  In response to this instruction, a scan setting selection screen is displayed on the display of the external device. When one scan setting is selected from the drop-down list and the selection decision is input to the external apparatus, selection information indicating the selected scan setting is transmitted from the external apparatus to the image reading apparatus 1. Is done. When the image reading apparatus 1 receives this selection information, the CPU 56 starts reading the image of the document S based on the scan setting indicated by the selection information (S23 in FIG. 5A).

  In this manner, the processes of steps S23 to S31 are repeated, and the image of the document S is read by the scan setting in which the use order is the last in the scan setting group specified by the workflow number of the document bundle reading job. When the document S supported on the tray 12 runs out (S24: NO), the scan setting currently in use is the last scan setting (S25: YES), so the CPU 56 determines that the maximum number of read documents is ADF. It is determined whether or not the number of stacked sheets is exceeded (S33).

  When the number of read documents does not exceed the maximum ADF stack number (S33: NO), the CPU 56 determines whether the confirmation information of the last scan setting indicates that confirmation of using the scan setting is necessary. (S34).

  When the confirmation information on the scan setting in the next order indicates that confirmation of using the scan setting is not necessary (S34: NO), the CPU 56 ends the document bundle reading process.

  On the other hand, when the confirmation information on the scan setting in the next order indicates that it is necessary to confirm that the scan setting is to be used (S34: YES), the CPU 56 determines whether or not the document S is supported on the tray 12 by the addition. (S35).

If the original S is not added within a predetermined time after the original S supported on the tray 12 is exhausted (S35: NO), the CPU 56 ends the original bundle reading process.
When an input indicating the end of the document bundle reading process is performed on the external apparatus and an instruction to end the document bundle reading process is received from the external apparatus in response to the input, the document S supported on the tray 12 is received. The document bundle reading process may be terminated without waiting for a predetermined time after the time has elapsed. When the image reading apparatus 1 is provided with an operation unit including various operation keys and a display unit such as a liquid crystal display, an instruction to end the document bundle reading process may be given by an input to the operation unit.

  When the original S is supported on the tray 12 by adding within a predetermined time (S35: YES), the CPU 56 keeps the last scan setting currently in use (S36), and the image of the original S by the scan setting. Is read by the image reading units 31 and 32 (S23). Thereafter, the processes of steps S23 to S25 and S33 to S36 are executed.

<Effect>
As described above, in order to execute the document bundle reading job, the RAM 58 stores, for each scan setting used in the document bundle reading job, the contents, the workflow number for identifying the workflow in which the scan setting is used, and the workflow. The order of use of scan settings is registered.

  When an instruction to start reading an image of the document S is instructed, the scan setting of the usage order “1” included in the group of scan settings used in the document bundle reading job is read from the RAM 58 and the usage order of “1”. Reading of the image of the document S by the scan setting is started. When there is no document S supported on the tray 12 and the document S is supported on the empty tray 12 by addition, the number of documents S on which images are read with the scan setting of use order “1” is predetermined. It is determined whether the number of sheets is equal to or greater than the maximum number of ADF sheets that can be supported on the tray 12. When the number of documents S is less than the predetermined number and the confirmation information of the scan setting in the usage order “2” indicates that confirmation is not required, the scan in the usage order “2” next to the usage order “1” is read from the RAM 58. The setting is read, and the image of the document S added to the tray 12 is read using the scan setting of the usage order “2”.

  Therefore, it is possible to eliminate the need to perform scan settings for the document S added to the tray 12. As a result, it is possible to reduce the user's trouble when reading images of a plurality of documents S while switching scan settings.

  When the number of documents S from which images have been read with the scan setting of the usage order “1” is less than the predetermined number and the confirmation information of the scan setting of the usage order “2” indicates confirmation, the scan setting selection screen is displayed. Displayed on the display of the external device. When the scan setting is selected on the scan setting selection screen, the image of the document S added to the tray 12 is read using the scan setting. In this case, the scan setting of usage order “2” is displayed in the drop-down list by default. Therefore, when using the scan setting of the usage order “2”, it is possible to save the user from setting the scan setting of the usage order “2”.

  On the other hand, when the number of documents S from which images are read with the scan setting of the usage order “1” is equal to or greater than the predetermined number, a scan setting selection screen is displayed on the display of the external device. When the scan setting is selected on the scan setting selection screen, the image of the document S added to the tray 12 is read using the scan setting. In this case, the user can select an arbitrary scan setting, and the image of the document S can be read with the selected scan setting.

  All the scan settings included in the scan setting group used in the document bundle reading job are used for reading the image of the document S, and more than a predetermined number of images of the document S are read using the last scan setting. In this case, even if the original S is added to the tray 12, the original S is read using the last scan setting without newly setting the scan setting. For this reason, it is not necessary for the user to select a scan setting to be used for reading an image of the document S, and the user's labor can be reduced.
