Image reading device

Abstract

When performing a continuous single-page scan, the image reader repeatedly switches between standby and scanning states, causing the display on the casing's LCD to flicker rapidly. [Solution] The system includes a display unit 105 that displays information about the image reading device 100 on the screen, a control unit 101 that controls the screen transitions of the display unit 105, and a storage unit 104 that stores the screen transition controls performed by the control unit 101. When a second scan operation (scanning a predetermined number of images), which is different from the first scan operation (normal scan), is completed, if conditions such as the presence of a transport medium S on the mounting table 1 are met, the system performs a second screen transition that does not immediately transition to the standby screen.

Description

Technical Field

[0001] The present invention relates to an image reading apparatus that reads an image while conveying a document.

Background Art

[0002] Some image reading apparatuses (such as image scanners, copiers, facsimile machines, etc.) feed stacks of documents placed on a placement table one by one into a housing by an automatic document feeder (ADF: Auto Document Feeder) and read image data of the documents by a CIS (Contact Image Sensor).

[0003] In recent years, many image reading apparatuses have a UI (User Interface) such as an LCD (Liquid Crystal Display) or an OLED (Organic Light Emitting Diode) provided in the housing, and by displaying the state of the image reading apparatus, the number of scanned sheets of the document stack, etc. on these UIs, the user-friendliness is improved.

[0004] When an image reading apparatus equipped with an automatic document feeder starts normal scanning, it feeds stacks of documents placed on the placement table one by one and acquires image data of all the documents. However, some image reading apparatuses feed only one sheet from the stack of documents placed on the placement table when starting the operation, perform scanning, and once the operation is completed, automatically repeat this to scan all the stacks of documents (hereinafter, this operation is referred to as continuous single-sheet scanning). This continuous single-sheet scanning function is mainly one of the functions requested from the image output destination system. However, when performing continuous single-sheet scanning, the image reading apparatus repeats the change between the standby state and the scanning state, so the display on the UI such as the LCD of the housing switches rapidly (hereinafter, the rapid switching of the UI display is expressed as flickering), which may give the user a sense of discomfort or suspicion of malfunction.

[0005] In contrast, Patent Document 1 discloses a technology that determines the status of the machine, the setting of the operating mode, and the content displayed on a display unit such as an LCD, and displays external input display data (such as a maintenance request screen) on the display unit, thereby enabling the external input data to be displayed automatically at a timing that does not interfere with the operation of the image forming means.

[0007] However, in configurations such as Patent Document 1, where the content to be displayed on the display unit is determined from the state of the machine and its operating mode, it is difficult to prevent screen flickering in situations where the state of the image reading device changes rapidly, such as in continuous single-image scanning. [Means for solving the problem]

[0011] The embodiments will be described in detail below with reference to the attached drawings. Note that the following embodiments do not limit the invention as defined in the claims. While the embodiments describe multiple features, not all of these features are essential to the invention, and the features may be combined in any way. Furthermore, in the attached drawings, identical or similar configurations are given the same reference numerals, and redundant descriptions are omitted.

[0012] <Explanation of the configuration of the image reading device> Figure 1 shows an example of the main hardware configuration of the image reading device 100 according to this embodiment. Note that the configuration shown in Figure 1 is just one example and may include other parts.

[0013] The CPU (control unit) 101 performs overall control of the operations of each part constituting the image reading apparatus 100 using the computer programs and data stored in the storage unit 104.

[0014] The conveyance unit 102 conveys the conveyance medium S into the image reading apparatus 100 and discharges it outside the housing using the method to be described later in FIG. 2.

[0015] The image reading unit 103 acquires the image of the conveyance medium S conveyed by the conveyance unit 102 by the method to be described later in FIG. 2.

[0016] The storage unit 104 functions as a work area used when the CPU 101 executes various processes and a storage area for temporarily storing images read by the image reading unit and the like. The storage unit 104 is composed of a storage medium such as, for example, a RAM (Random Access Memory) or a ROM (Read Only Memory). The storage unit 104 does not necessarily need to have all its areas installed inside the housing. For example, a storage medium area of an external device (such as a USB Memory) connected to the image reading apparatus 100 may be used as part of the storage area to save images and the like.

[0017] The display unit 105 displays information such as the state of the main body of the image reading apparatus 100, scan settings, and the image of the conveyance medium S to the user. The display unit 105 may be, for example, an output device such as an LCD or an OLED, or may also be an input / output device such as a touch panel that combines both functions.

[0018] The interface unit 106 is an interface for communicating information with an external information processing device. Assuming a PC (Personal Computer) as the external information processing device, the interface unit 106 could be, for example, a USB (Universal Serial Bus) interface or a SCSI (Small Computer System Interface). In addition to such wired communication interfaces, the interface unit 106 may also employ a wireless communication interface, and may therefore have both wired and wireless communication interfaces.

[0019] <Explanation of the structure of the image reading device> The structure of the image reading device according to the present invention will be explained with reference to Figure 2. As shown in Figure 2, the image reading device 100 reads the transport medium S, which is the object to be scanned and transported by the ADF, using the CIS and generates image data. The loading platform 1 holds one or more transport media S. The transport media S is, for example, a sheet of OA paper, a check, a card, etc., and may be a thick or thin sheet. Examples of cards include insurance cards, driver's licenses, credit cards, etc. The transport media S also includes booklets such as passports.

[0020] The first transport unit 10 is a transport mechanism that supplies the transport medium S to the path RT. The first transport unit 10 has a feed roller 11 and a separation roller 12 positioned opposite the feed roller 11. The feed roller 11 and the separation roller 12 transport only one of the multiple transport media S placed on the mounting base 1 in the transport direction D1. The drive unit 3 is a motor or the like. The drive unit 3 transmits driving force to the feed roller 11 via the transmission unit 4, causing the feed roller 11 to rotate. The direction of rotation of the feed roller 11 is counterclockwise (the direction in which the transport medium S is transported along the path RT). The transmission unit 4 is, for example, an electromagnetic clutch, and intermittently (cuts off / connects) the driving force from the drive unit 3 to the feed roller 11 according to instructions from the control unit 8. The transmission unit 4 is normally in a state of transmitting driving force, and cuts off the driving force when transporting the transport medium S in reverse. When the transmission of driving force to the feed roller 11 is cut off by the transmission unit 4, it becomes capable of free rotation. If the feed roller 11 is driven in only one direction, the transmission unit 4 may be omitted.

[0021] The separation roller 12 is a roller for separating multiple conveying media S into individual sheets, and is pressed against the feed roller 11 with constant pressure. To ensure this pressure contact, the separation roller 12 is provided to be swingable and is biased against the feed roller 11 by a spring or the like. The separation roller 12 rotates counterclockwise when a driving force is transmitted from the drive unit 3 via a torque limiter 12a. The driving force of the separation roller 12 is restricted by the torque limiter 12a. Therefore, when the separation roller 12 is in contact with the feed roller 11, the separation roller 12 rotates together with the feed roller 11. As a result, when multiple conveying media S are conveyed to the pressure contact area between the feed roller 11 and the separation roller 12, only one conveying media S is conveyed downstream, and the remaining conveying media S are blocked from being conveyed downstream. In this embodiment, the separation mechanism is configured with the separation roller 12 and the feed roller 11, but this is just one example. The separation mechanism may be omitted, or a separation mechanism consisting of a separation pad that applies frictional force to the conveying medium S and a feed roller 11 may be employed.

[0022] A second conveying section 20 is provided downstream of the first conveying section 10 in the conveying direction. The second conveying section 20 has a drive roller 21 and a driven roller 22 that moves with the drive roller 21. The second conveying section 20 further conveys the conveying medium S that has been conveyed from the first conveying section 10 to the downstream side. The drive roller 21 receives driving force from the drive section 3 and rotates counterclockwise. The driven roller 22 is pressed against the drive roller 21 with constant pressure and therefore rotates along with the drive roller 21. The driven roller 22 may be biased against the drive roller 21 by a biasing unit (not shown), such as a spring.

[0023] A third conveying section 30 is provided downstream of the second conveying section 20 in the conveying direction. The third conveying section 30 has a drive roller 31 and a driven roller 32 that moves with the drive roller 31. The third conveying section 30 conveys and discharges the conveying medium S conveyed from the second conveying section 20 to the discharge tray 2. The drive roller 31 receives driving force from the drive section 3 and rotates counterclockwise. The driven roller 32 is pressed against the drive roller 31 with constant pressure and rotates along with the drive roller 31. The driven roller 32 may be biased against the drive roller 31 by a biasing unit such as a spring.

[0024] In the route RT, image reading units 70a and 70b are positioned between the second transport unit 20 and the third transport unit 30. Image reading unit 70a reads the first surface of the transport medium S. Image reading unit 70b reads the second surface of the transport medium S. For image reading, the second transport unit 20 and the third transport unit 30 transport the transport medium S at a constant transport speed. This transport speed may always be set to be higher than or equal to the transport speed of the first transport unit 10. This prevents the following transport medium S from colliding with the preceding transport medium S.

[0025] The double-feed sensor 40 is positioned between the first transport unit 10 and the second transport unit 20. The double-feed sensor 40 detects double-feeding of the transport medium S. Double-feeding is a phenomenon in which multiple transport mediums S become attached to each other due to static electricity or the like, and pass through the first transport unit 10. Various types of double-feed sensors 40 can be used. For example, the double-feed sensor 40 may be an ultrasonic sensor. In this case, the double-feed sensor 40 has an ultrasonic transmitter 41 and a receiver 42. The amount of attenuation of the ultrasonic waves passing through the transport medium S differs depending on whether multiple transport mediums S are being transported or whether only one transport medium S is being transported. Double-feeding is detected based on this principle.

[0026] In the transport path RT, a medium sensor 50 is positioned downstream of the double-feed sensor 40 in the transport direction. The medium sensor 50 is positioned upstream of the second transport unit 20 and downstream of the first transport unit 10. The medium sensor 50 detects the position of the transport medium S being transported by the first transport unit 10. More specifically, the medium sensor 50 detects whether the end of the transport medium S has reached or passed the detection position of the medium sensor 50. Various types of medium sensors 50 can be used. For example, the medium sensor 50 may be an optical sensor. In this case, the medium sensor 50 has an illumination unit 51 and a light receiving unit 52. The light reception intensity of the light receiving unit 52 changes when the transport medium S reaches or passes through. The transport medium S is detected based on this principle. The medium sensor 50 is positioned downstream of the double-feed sensor 40 so that when the leading edge of the transport medium S is detected by the medium sensor 50, the transport medium S has reached a position where the double-feed sensor 40 can detect double-feeding. The medium sensor 50 may be a sensor capable of detecting the end of the transport medium S (e.g., an image sensor), or it may be a lever-type sensor protruding from the path RT.

[0027] The medium sensor 60 is located upstream of the image reading units 70a and 70b and downstream of the second transport unit 20. The medium sensor 60 detects the position of the transport medium S being transported by the second transport unit 20. Similar to the medium sensor 50, various types of medium sensors 60 can be used. Here, as an example, the medium sensor 60 is an optical sensor equipped with a light-emitting unit 61 and a light-receiving unit 62. In Figure 2, the medium sensors 50 and 60 are located upstream and downstream of the transport direction of the second transport unit 20, but only one of them may be located.

[0028] The image reading units 70a and 70b are line sensors that, for example, optically scan the transport medium S along the main scanning direction for each reading line, convert the light from the transport medium S into an electrical signal, and generate an image signal. The image reading units 70a and 70b include a light source such as an LED, a light guide, a light receiving sensor array, etc. Only one of the image reading units 70a and 70b may be placed on one side of the path RT. In Figure 2, the image reading units 70a and 70b are placed opposite each other with the path RT in between, but this is just one example. The image reading units 70a and 70b may be placed spaced apart in the direction of the path RT.

[0029] When the control unit 8 receives an instruction to start image reading, the drive unit 3 starts driving the first transport unit 10, the second transport unit 20, and the third transport unit 30. The transport media S loaded on the platform 1 are transported one by one, starting from the transport media S at the bottom. During transport, the transport media S are checked by the double-feed sensor 40 to determine if there is a double feed. If it is determined that there is no double feed, the transport of the transport media S continues. If it is determined that there is a double feed, the control unit 8 stops the drive unit 3 and stops the transport of the transport media S.

[0030] The control unit 8 initiates image reading of the transport medium S by the image reading units 70a and 70b at a timing corresponding to the detection result of the medium sensor 60. The control unit 8 converts the image signals output from the image reading units 70a and 70b into image data. The transport medium S is finally ejected into the discharge tray 2.

[0031] <Explanation regarding continuous single-page scanning and display flicker> Using Figures 3 and 4, the flickering of the display unit 105 during continuous single-page scanning of the image reading device 100 according to this embodiment will be explained.

[0032] In continuous single-sheet scanning, when the image reader 100 starts scanning, it feeds only one sheet at a time from the multiple transport media S loaded on the tray 1, acquires image data, and then ends the scanning operation. This is repeated to scan multiple transport media S. This continuous single-sheet scanning function is mainly requested due to the requirements of the image output destination system of the image reader 100. For example, it is used in systems where it is necessary to acquire image data for all of the transport media S, but specific processing must be performed on each image (or every two images if the scan setting is double-sided scanning), and once that processing is completed, the next transport media S is scanned, making it impossible to capture all image data at once.

[0033] When the image reading device 100 is not performing a scan, it displays a standby screen 80, such as the one shown in Figure 3. The content of the standby screen 80 is not limited to any screen that is not displayed during a scan. For example, it may display the communication status of the interface unit 106, information related to various settings of the image reading device 100, or a list of scan settings (JOBs) previously saved in the storage unit 104 from an external information processing device (not shown).

[0034] Furthermore, when the image reading device 100 is in scanning mode, it displays a scanning screen 81, for example, as shown in Figure 4. The content of the scanning screen 81 is not limited to what is displayed during scanning. For example, it may display the number of transport media S being transported in real time, or it may display the scan settings.

[0035] When performing a continuous single-page scan, the state of the image reading device 100 frequently switches between standby and scanning states. As a result, the display unit 105 also frequently switches between the standby screen 80 and the scanning screen 81, causing the display unit 105 to flicker.

[0036] <Flowchart for resolving display flicker during continuous single-page scanning> The process for eliminating flickering of the display unit during continuous single-image scanning of the image reading device 100 according to this embodiment will be explained using the flowchart in Figure 5.

[0037] In step S1000, the image reading device 100 starts the process of scanning one image at a time.

[0038] In step S1001, the image reading device 100 stores in the storage unit 104 the conditions for controlling the screen displayed on the display unit 105 by the control unit 101. As a condition for controlling the screen, in this embodiment, if a transport medium S is detected on the loading table 1, a delay time is set before the display on the display unit 105 transitions to the standby screen 80. The conditions for controlling the screen are not limited to this condition. For example, even after scanning one transport medium S is completed and image data is output, other conditions may be used, such as not transitioning the display on the display unit 105 to the standby screen 80 until an instruction is received from an external information processing device. Furthermore, regarding the control that sets a delay time, the value of the delay time is not limited as long as it is longer than the transition time to the standby screen 80 when not performing a continuous single-sheet scan. For example, the time may be changed depending on whether or not a transport medium S is loaded on the loading table 1. In addition, the conditions for controlling the screen are stored in the storage unit 104 via the interface unit 106 from an external information processing device such as a PC (not shown). However, this is not the case if the configuration allows for saving the conditions for controlling the screen in the storage unit 104. For example, the conditions may be saved in the storage unit 104 using input units not shown, such as hard buttons or touch panels mounted on the image reading device 100.

[0039] In step S1002, the image reading device 100 checks whether the transport medium S1 is loaded on the mounting table 1. If it is loaded, the process proceeds to step S1003. If it is not loaded, the process proceeds to step S1006.

[0040] In step S1003, the image reading device 100 receives instructions regarding the number of scans from the external information processing device such as the PC mentioned above in step S1001. In this embodiment, a continuous single-page scan is illustrated, so the number of scans is specified as 1, but this is not limited to this. For example, if the image data output destination system of the image reading device 100 requests the output of multiple images, the number of scans may be a predetermined number other than 1, and these may all be referred to as a predetermined number of scans.

[0041] In step S1004, the image reading device 100 feeds one sheet of the transport medium S and scans it using the method described above in <Explanation of the structure of the image reading device>. At this point, the control unit 101 displays the scanning screen 81 on the display unit 105.

[0042] In step S1005, the image reading device 100 finishes scanning one of the transport media S. At this point, the control unit 101 controls the display unit 105 according to the conditions for controlling the screen stored in the storage unit 104 in step S1001. If no conditions for controlling the screen are specified, the control unit 101 displays the standby screen 80 on the display unit 105 when the scan is completed. In this embodiment, since the storage unit 104 stores the condition for controlling the screen that even if image data from the transport media S is output in step S1001, the display will not transition to the standby screen 80 until instructed by an external information processing device, the control unit 101 does not change the display on the display unit 104 from the scanning screen 81. As a result, even when performing continuous single-page scans, the display content of the display unit 104 does not frequently switch between the standby screen 80 and the scanning screen 81, preventing the user from seeing the display on the display unit 104 flicker.

[0043] In step S1006, the image reading device 100 completes the process of scanning a single image consecutively.

[0044] <Explanation regarding display flicker in continuous mode> Using Figures 6 to 8, the flickering of the display unit 105 in the continuous mode of the image reading device 100 according to this embodiment will be explained.

[0045] In this embodiment, the continuation mode is a mode in which, when the image reading device 100 finishes or interrupts scanning, the user is asked to confirm whether to continue scanning. For example, when the image reading device 100 finishes scanning in continuation mode, the continuation confirmation screen 82 shown in Figure 6 is displayed on the display unit 105 to ask the user whether to scan another transport medium S. If the user selects to continue scanning, the scan continues with the same document stack as the transport medium S scanned immediately before. Also, if an event occurs that interrupts scanning in continuation mode, for example, if double feeding of the transport medium S is detected using the method described above in <Explanation of the Structure of the Image Reading Device>, the continuation error confirmation screen 83 shown in Figure 7 is displayed on the display unit 105 to ask the user whether to handle the acquired image data (discard, save) and whether to continue scanning the transport medium S. The event that interrupts scanning as described above is not limited to double feeding. For example, in a configuration where scanning is interrupted when skew of the transport medium S is detected, the continuation error confirmation screen 83 may be displayed on the display unit 105 when skew is detected in continuation mode.

[0046] In this embodiment, the continuation error confirmation screen 83 is sent from the external information processing device to the image reading device 100. On the other hand, if an event occurs that interrupts scanning during continuous mode, the control unit 101 displays the error screen 84 shown in Figure 8 on the display unit 105 to notify the user that scanning has been interrupted. However, immediately after the event that interrupts scanning occurs, the driver in the external information processing device detects that an error has occurred, and the continuation error confirmation screen 83 is sent from the external information processing device. As a result, the control unit 101 switches the display on the display unit 105 from the error screen 84 to the continuation error confirmation screen 83. Due to the display control caused by the error in the image reading device 100 in the control unit 101 and the display control instructed by the external information processing device, the display on the display unit 105 switches rapidly, resulting in flickering of the display unit 105.

[0047] <Flowchart for resolving display flicker in continuous mode> The process for eliminating flickering of the display unit in the continuous mode of the image reading device 100 according to this embodiment will be explained using the flowchart in Figure 9.

[0048] In step S2000, the image reading device 100 starts the scanning process in continuous mode.

[0049] In step S2001, the image reading device 100 saves the conditions for controlling the display unit 105 in the storage unit 104 in the same manner as in step S1001 of the flowchart for eliminating display unit flicker during continuous single-image scanning. In this embodiment, when an event occurs in continuous mode that interrupts scanning as described in the explanation of display unit flicker in continuous mode, a control to delay the transition to the error screen 84 is saved in the storage unit 104. Furthermore, the delay time in this delay control is not limited to a specific value, as long as it is longer than the transition time to the error screen 84 in modes other than continuous mode.

[0050] In step S2002, the image reading device 100 checks whether the transport medium S1 is loaded on the mounting table 1. If it is loaded, the process proceeds to step S2003. If it is not loaded, the process proceeds to step S2008.

[0051] In step S2003, the image reading device 100 starts scanning the transport medium S. At this point, the control unit 101 displays the scanning screen 81 on the display unit 105.

[0052] In step S2004, the image reading device 100 checks whether the phenomenon that interrupts the scan, as described in step S2001, has occurred. If the phenomenon that interrupts the scan has occurred, the process moves to step S2006. If the phenomenon that interrupts the scan has not occurred, the process moves to step S2005.

[0053] In step S2005, the image reading device 100 completes the scan of the transport medium S that was started in step S2003.

[0054] In step S2006, the image reading device 100 performs the process for interrupting the scan as described in step S2001. Since the conditions for controlling the screen are stored in the storage unit 104 in step S2001, this process includes a delay before the control unit 101 displays the error screen 84 on the display unit 105.

[0055] In step S2007, the image reading device 100 performs control to confirm with the user whether to continue scanning. Here, the control unit 101 displays the continuation error confirmation screen 83 on the display unit 105. If the process transitions from step S2006 to this stage via step S2005, and the conditions for controlling the display unit 105 in step S2001 are not saved, the display unit 105 will quickly switch from the error screen 84 to the continuation error confirmation screen 83, causing flickering. However, since the conditions for controlling the display unit 105 in step S2001 include a control that delays the transition to the error screen 84 if an event occurs that interrupts scanning, the control unit 101 delays the display of the error screen 84 in step S2006. By transitioning from step S2005 to step S2007 within this delay time, if the continuation error confirmation screen 83 is sent from the external information processing device, the control unit 101 can cancel the control to display the delayed error screen 84 and prioritize the display of the screen sent from the external information processing device. This control prevents flickering of the display unit 105 due to the rapid switching of the display from the error screen 84 to the continuation error confirmation screen 83. Subsequently, if the user selects to continue scanning, the process moves to step S2002. If the user selects to end the scan, the process moves to step S2008.

[0056] In step S2008, the image reading device 100 terminates the scanning process in continuous mode.

[0057] In the example above, a predetermined delay time was set as a control to cause a delay, but instead of delaying, it may be set to prevent transitioning to the error screen 84.

[0058] As described above, according to the present invention, by saving screen control for specific conditions met in a specific operating mode (for example, delaying screen transitions when a document is loaded on the document glass at the end of a single-page scan during continuous single-page scanning, delaying screen transitions when a double-feed error occurs during continuous scanning, etc.) in the storage unit, it is possible to prevent screen flickering caused by the momentary display of a specific screen.

[0059] Furthermore, the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. For example, in the above embodiments, an example was described in which the screen control is saved to the storage unit 104 in S1001 and S2001, but it may also be saved to the storage unit 104 at other times, or the screen control may be saved to the storage unit 104 so that its settings are always applied.
