  Next, the configuration of the ADF 5 and the image reading unit 4 will be described with reference to FIG. FIG. 2 is a cross-sectional view illustrating a configuration of the image processing apparatus 1.

  The image processing apparatus 1 is configured such that its operation mode can be switched between a flatbed scanner mode (placed document reading mode) and a DF scanner mode (conveyed document reading mode).

  The flatbed scanner mode is a mode for reading an image of the original 300 placed on the flatbed contact glass 41. In the flatbed scanner mode, the image reading unit 4 irradiates light on the image surface of a document 300 (for example, a document sheet, cardboard, book, etc.) on the flatbed contact glass 41, and reflects the reflected light from the image surface as an image. The image of the original 300 can be read by converting the signal.

  The DF scanner mode is a mode in which the image reading unit 4 reads an image of the document 300 during automatic conveyance in the reverse conveyance path 52 or the straight conveyance path 60. In the DF scanner mode, the ADF 5 separates the originals 300 one by one from the bundle of originals 300 stacked on the original tray 51 by the pickup roller 52 a and carries them into the reverse conveyance path 52. The ADF 5 transports the document 300 along the reverse transport path 52 (see FIG. 5A). While being conveyed along the reverse conveyance path 52, the original 300 sequentially faces the DF contact glass 42 on the upper surface side of the image reading unit 4 sequentially from the upstream side in the conveyance direction. That is, the image processing apparatus 1 can exhibit the function of the DF scanner by sequentially reading the image on the document 300 conveyed by the ADF 5 on the DF contact glass 42 of the image reading unit 4.

  The ADF 5 is attached to a rear portion (a portion on the back side) of the upper surface side of the apparatus main body 1M via an opening / closing mechanism such as a hinge. The ADF 5 can adopt an open position where the flat body contact glass 41 is opened with respect to the apparatus main body 1M and a closed position where the document 300 on the flat bed contact glass 41 can be pressed.

  Next, the configuration of the image reading unit 4 will be described with reference to FIG. FIG. 3 is a diagram illustrating a configuration of the image reading unit 4.

  In the image reading unit 4, the flatbed contact glass 41 faces the image surface of the original 300 when the image processing apparatus 1 functions as a flatbed scanner and the original 300 to be read is placed. It has become. Further, the DF contact glass 42 faces the image surface of the document 300 passing through a predetermined reading position of the reverse conveyance path 52 when the image processing apparatus 1 functions as a DF scanner. Further, the surface 42 a of the DF contact glass 42 is inclined with respect to the surface 41 a of the flat bed contact glass 41 so as to form a preset inclination angle θ.

  A reading unit 45 and a guide rod 46 are provided inside the image reading unit 4. The guide rod 46 extends in the left-right direction in FIG. The reading unit 45 is configured to be able to travel along the guide rod 46. The reading unit 45 includes an integrated optical scanning unit 47, a bracket 48, and a plurality of compression coil springs 49. The bracket 48 holds the integrated optical scanning unit 47. Each compression coil spring 49 is assembled between the integrated optical scanning unit 47 and the bracket 48 in a compressed state.

  The integrated optical scanning unit 47 is configured, for example, as a contact image sensor in which a mold frame is held with an equal magnification imaging element roof mirror lens array, an optical path separation mirror, an equal magnification image sensor, an illumination light source, and the like. The integrated optical scanning unit 47 can scan an image with high resolution in the main scanning direction, and has a large focal point capable of reading an image of a thick original 300 (for example, thick paper, a book, etc.). It is configured to have a depth.

  The integrated optical scanning unit 47 is not limited to a specific method as long as the integrated optical scanning unit 47 is configured to be compatible with a DF scanner and a flat bed scanner. The main scanning direction is a direction parallel to both the upper surface of the flat bed contact glass 41 and the upper surface of the DF contact glass 42 (a direction substantially perpendicular to the paper surface of FIG. 3).

  The bracket 48 includes a lower slider portion 48a, a pair of holding arm portions 48b, and a bracket body portion 48d. The lower slider portion 48 a is supported by the guide rod 46. The pair of holding arm portions 48 b holds the integrated optical scanning unit 47. The bracket main body portion 48d is integrally mounted with a lower slider portion 48a and a pair of holding arm portions 48b.

  Here, the lower slider portion 48a is formed of a cylindrical body fixed to the lower portion of the center in the longitudinal direction of the bracket main body portion 48d, and the pair of holding arm portions 48b are located on the upper side in the figure at both end sides of the bracket main body portion 48d. It is comprised by a pair of plate-shaped body which protrudes. The pair of holding arm portions 48b are arranged in the vertical direction so as to hold the both-end protruding portions 47a protruding vertically from both end faces of the integrated optical scanning unit 47 so that the posture can be changed around the longitudinal axis and the vertical displacement is possible. Has a long hole (oblong hole) 48c.

  The plurality of compression coil springs 49 press the lower surface portion of the integrated optical scanning unit 47 to the upper side (flat bed contact glass 41 side, DF contact glass 42 side) at a plurality of locations in the main scanning direction.

  In addition, on the upper part of the integrated optical scanning unit 47, a rectangle that slides smoothly in the sub-scanning direction (left-right direction in FIG. 3) while being in contact with the lower surface of at least one of the flat bed contact glass 41 and the DF contact glass 42. An annular upper slider portion 47b is mounted.

  The upper slider portion 47b may be a protrusion that extends in the longitudinal direction or the short side direction of the integrated optical scanning unit 47 and is spaced apart from each other in a direction orthogonal to the extending direction.

  Further, the upper slider portion 47b may be composed of a plurality of hemispherical protrusions or the like. In any case, the upper slider portion 47b is made of a material that has a low coefficient of friction, good slidability / slidability with respect to the lower surface of the flat bed contact glass 41 and the DF contact glass 42, or an alternative guide surface, and can be lubricated. It should be formed.

  The integrated optical scanning unit 47 is also guided by a guide rod 46 disposed below the bracket 48 so as to be movable in the sub-scanning direction. Depending on the position in the sub-scanning direction, the integrated optical scanning unit 47 is slidably brought into contact with one or both of the flat bed contact glass 41 and the DF contact glass 42 at the upper part. Thereby, the reading unit 45 is movable along the guide rod 46, but the inclination of the guide rod 46 around the axis is restricted.

  The reading unit 45 performs line scanning on the image surface of the original 300 on the flat bed contact glass 41 in the main scanning direction (a direction substantially perpendicular to the paper surface in FIG. 3) and in the sub-scanning direction (the horizontal direction in FIG. 3). ), The image of the original 300 can be read.

  The reading unit 45 can read the image of the document 300 by performing line scanning on the image of the document 300 passing over the DF contact glass 42 in the main scanning direction.

  In addition, a timing belt in which a bracket 48 of the reading unit 45 is fixed at one place in the circumferential direction in an endless loop shape is provided inside the image reading unit 4.

  The image reading unit 4 includes a plurality of timing pulleys on which the timing belt is stretched without slack, a motor that rotationally drives any one of the timing pulleys, and the like.

  When performing the reading operation in the flat bed scanner mode, the reading unit 45 moves from the home position to one side in the sub-scanning direction, for example, from the home position near the stop position (the position indicated by the solid line in FIG. 2) to the right side in the drawing. Move to. Then, line scanning by the integrated optical scanning unit 47 is executed for each minute movement distance, and an image on the surface (lower surface) of the document 300 placed on the flat bed contact glass 41 is read. When the reading operation is completed, the reading unit 45 returns to the home position again.

  When performing a reading operation in the DF scanner mode, the reading unit 45 moves from a home position (a position indicated by a solid line in FIG. 2) to a position below the DF contact glass 42 (a position indicated by a broken line in FIG. 2). That is, the reading unit 45 moves to the other side in the sub-scanning direction by a preset distance from the home position, stops at a position below the DF contact glass 42, and moves on the surface of the document 300 passing over the DF contact glass 42. Read the image.

  In this way, the reading unit 45 is movable in the sub-scanning direction so as to be positioned on the lower side of the flat bed contact glass 41 and the lower side of the DF contact glass 42. The integrated optical scanning unit 47 has a horizontal first reading posture in which an image can be read through the flat bed contact glass 41 and an inclined second image in which an image can be read through the DF contact glass 42 according to the position in the sub-scanning direction. The posture changes to the reading posture.

  The ADF 5 includes a document tray 51 serving as a document placement table on which a standard sheet can be placed, a reverse conveyance path 52 that conveys the document 300 in an image-readable manner, and a discharge tray 53 that stacks the document 300 after image reading. It has. The document tray 51 and the paper discharge tray 53 are arranged one above the other with at least a part of them separated for the purpose of downsizing.

  In the image processing apparatus 1, for example, it is required to select a desired setting from a plurality of settings for a reading process of scanning the original 300 and acquiring an image of the original 300. At this time, the image processing apparatus 1 is desired to appropriately select the setting. For example, when the QR code (registered trademark) indicating the setting of the reading process is arranged on the document 300, the user does not always desire the image reading process with the setting indicated in the QR code (registered trademark).

  Therefore, in the present embodiment, the image processing apparatus 1 is configured such that a desired setting can be selected from a plurality of settings depending on which paper feed port the document 300 is inserted into. The image processing apparatus 1 performs an image reading process on the document 300 inserted into the first sheet feeding port 59 with the setting (second setting) received on the operation panel, and the second sheet feeding. The document 300 inserted into the mouth 72 is configured to perform image reading processing with the setting (first setting) indicated in the QR code (registered trademark). Accordingly, when reading processing with the setting accepted on the operation panel is desired, the original 300 is inserted into the first paper feed port 59, and reading processing with the setting indicated by the QR code (registered trademark) is desired. In addition, by inserting the original 300 into the second paper feed port 72, the setting can be appropriately selected in the image processing apparatus 1.

  For example, the second paper feed port 72 used when an image reading process with the setting indicated in the QR code (registered trademark) is desired is configured as shown in FIG. FIG. 4 is a perspective view showing the configuration of the second paper feed port 72.

  The ADF 5 has a straight conveyance path 60 for reading a document 300 such as a card or cardboard that cannot be conveyed by reverse conveyance. The straight conveyance path 60 (see FIG. 5B) is a conveyance path including the downstream side of the roller pairs 52e and 52c, which are a part of the reverse conveyance path 52, from the second paper supply port 72 to the paper discharge port. This refers to the transport route up to 56. The card here is an ID card (identification card), a transportation card or the like. The size of the card is, for example, one of ID-1, ID-2 and ID-3 of ISO / IEC 7810, which is an international standard that defines the shape of an ID card, or a size comparable to that.

  When the straight conveyance path 60 is used, the documents 300 are manually inserted and inserted one by one from the second paper feed port 72. The second paper feed port 72 can feed paper by opening the openable manual document tray 73. The manual document tray 73 is normally closed, constitutes a part of the side surface of the cover 55, and is rotatable so as to open the second paper feed port 72. A manual feed set detection sensor 74 is provided near the entrance of the second paper feed port 72, and detects that the document 300 is inserted from the second paper feed port 72. When the insertion of the document 300 is detected by the manual feed detection sensor 74, the roller pair 52e, 52c is rotated after a predetermined time has elapsed, and the roller is detected when the leading edge of the document 300 is detected by the registration sensor 57 downstream of the roller pair 52e, 52c. The rotation of the pair 52e, 52c is stopped, and the document 300 is held and held in this state. The roller pairs 52e and 52c hold the original 300 and wait, and then when the reading operation command is given, the next original 300 is conveyed to the straight conveyance path 60.

  The reverse conveyance path 52 is a path for conveying the original 300 inserted into the first paper feed port 59 when an image reading process with the setting accepted on the operation panel is desired, as shown in FIG. It has a configuration. FIG. 5A is a cross-sectional view showing the reverse conveyance path 52. The straight conveyance path 60 is a path for conveying the document 300 inserted into the second paper feed port 72 when an image reading process with the setting indicated by the QR code (registered trademark) is desired. It has the structure shown in b). FIG. 5B is a cross-sectional view showing the straight transport path 60.

  As shown in FIG. 5A, the reverse conveyance path 52 indicates a conveyance path from the first paper feed port 59 to the paper discharge port 56. The downstream portion of the reverse conveyance path 52 after the roller pairs 52e and 52c is shared with the straight conveyance path 60 (see FIG. 5B). A document set sensor 58 is provided near the entrance of the first sheet feed port 59 and detects that the document 300 is inserted from the first sheet feed port 59. When the document 300 is set on the document tray 51 in order to read the image of the document 300, the uppermost button is pressed by pressing the start button on the operation panel provided on the front surface of the apparatus main body 1M (see FIG. 2). The document is fed out from the document 300 to the reverse conveyance path 52 in order.

  For example, among the originals 300 placed on the original tray 51, the uppermost original 300 is picked up by the pickup roller 52a from the first paper feed port 59, and is transported in a U-turn by the roller pairs 52b and 52e and the roller pairs 52e and 52c. A U-turn is conveyed so as to be folded along the route. Thereafter, when the original 300 passes through the upper surface of the DF contact glass 42, it is brought into close contact with the DF contact glass 42 by the pressure of the reading roller 52 f, and is one surface (for example, the front surface) by the optical scanning unit 47 as an image sensor. The image is read. Further, when the original 300 passes through the optical scanning unit 69, an image on the other side is read by the optical scanning unit 69 while being in close contact with the optical scanning unit 69 by the pressure of the reading roller 70. Then, the original 300 after the image on the other side (for example, the back side) is read is discharged from the discharge port 56 toward the discharge tray 53 (see FIG. 2) by the discharge roller pairs 52d and 52g.

  As shown in FIG. 5B, the straight transport path 60 indicates a transport path from the second paper feed port 72 to the paper discharge port 56. Near the entrance of the second paper feed port 72, there is a manual feed set detection sensor 74 that detects that the document 300 has been inserted from the second paper feed port 72. The straight conveyance path 60 is a document smaller than the minimum size document 300 (for example, a postcard size) set in the document tray 51, particularly, a thick resin card such as a bank card or various credit cards. Can be transferred (delivered).

  That is, the straight conveyance path 60 is generally on the same plane, and the adjacent intervals between the card pickup rollers 75a and 75b, the roller pairs 52e and 52c, the reading roller 52f, and the paper discharge roller pairs 52d and 52g are thick. The document 300 (for example, card) S is arranged in a vertical size (or horizontal size) or less (see FIG. 4). As a result, when reading a document 300 (for example, a card), first, the manual document tray 73 is opened and the second paper feed port 72 is opened. In this state, a document 300 such as a card is set on the manual document tray 73, and the start button on the operation panel is pressed, so that the document is fed out to the straight conveyance path 60 in order from the topmost document 300 (for example, a card). .

  For example, the document 300 is picked up by the pickup rollers 75a and 75b from the second paper feed port 72 and conveyed by the roller pair 52e and 52c. Thereafter, when the original 300 passes through the upper surface of the DF contact glass 42, an image on one surface (for example, the front surface) is read by the optical scanning unit 47 while being in close contact with the DF contact glass 42 by the pressure of the reading roller 52f. . Further, when the document 300 (for example, a card) passes through the optical scanning unit 69, the optical scanning unit 69 reads an image on the other surface while being in close contact with the optical scanning unit 69 by the pressure of the reading roller 70. Then, the original 300 (for example, a card) after reading the image on the other side (for example, the back side) is directed from the sheet discharge port 56 toward the sheet discharge tray 53 (see FIG. 2) by the pair of sheet discharge rollers 52d and 52g. Discharged.

  As shown in FIGS. 5A and 5B, in the image processing apparatus 1, the paper is discharged from the reverse conveyance path 52 from the first paper feed port 59 to the paper discharge port 56 and from the second paper feed port 72. The downstream portion after the roller pair 52e, 52c is shared with the straight conveyance path 60 to the paper mouth 56. Thus, while contributing to downsizing of the ADF 5 and shortening of the reading time, it is possible to read the original 300 such as a small resin card having a large size and cope with the diversification of reading of the original 300.

  Next, the hardware configuration of the image processing apparatus 1 will be described with reference to FIG. FIG. 6 is a block diagram illustrating a hardware configuration of the image processing apparatus 1.

  The image processing apparatus 1 includes a registration sensor 57, a document set sensor 58, a manual feed set detection sensor 74, a paper discharge sensor 89, a bump sensor 85, a document width sensor 86, a reading entrance sensor 87, a table lift sensor 84, and a home position sensor 83. , Reading unit 45, pickup motor 101, paper feed motor 102, reading motor 103, paper discharge motor 104, bottom plate raising motor 105, paper discharge conveyance motor 91, red LED 75, blue LED 76, solenoid 78, controller unit 100, main body control unit 111 and an operation unit 150.

  The main body control unit 111 and the operation unit 150 are provided in the apparatus main body 1M. The main body control unit 111 controls each unit of the apparatus main body 1M. The operation unit 150 is attached to the main body control unit 111 and includes an operation panel 150a. The operation unit 150 receives various commands from the user via the operation panel 150 a and supplies them to the main body control unit 111.

  The controller unit 100 is disposed, for example, in the vicinity of the ADF 5 and the image reading unit 4 and performs various controls related to automatic document conveyance.

  For example, the controller unit 100 includes a registration sensor 57, a document set sensor 58, a manual feed set detection sensor 74, a home position sensor 83, a table lift sensor 84, a bump sensor 85, a document width sensor 86, a reading entrance sensor 87, and a paper discharge sensor.

The controller unit 100 responds to the detection signals of the various sensors taken in, and includes a pickup motor 101, a paper feed motor 102, a reading motor 103, a paper discharge motor 104, a bottom plate raising motor 105, a paper discharge conveyance motor 91, a red LED 75, and a blue color. Controls driving of various actuators such as the LED 76 and the solenoid 78.

  For example, the pickup motor 101 drives the pickup rollers 75a and 75b (see FIG. 2) according to control by the controller unit 100. The paper feed motor 102 drives the roller pairs 52b and 52e in accordance with control by the controller unit 100. The reading motor 103 drives the paper discharge roller pair 52e and 52d in accordance with control by the controller unit 100. The paper discharge motor 104 drives the paper discharge roller pair 52d and 52g according to control by the controller unit 100.

  The controller unit 100 and the main body control unit 111 are connected via an interface 107. When a key (for example, a start button) on the operation panel 150a of the operation unit 150 is pressed, the main body control unit 111 transmits a document feed command or a reading start command to the controller unit 100 via the interface 107. ing.

  Next, the functional configuration of the image processing apparatus 1 will be described with reference to FIG. FIG. 7 is a block diagram illustrating a functional configuration of the image processing apparatus 1.

  The image processing apparatus 1 includes a sensor receiving unit 201, an engine control unit 202, an operation panel control unit 203, a system control unit 204, a read data storage unit 205, a setting analysis unit 207, a QR code analysis unit 206, and a default setting recording unit 208. Have These functional configurations can be realized, for example, in the main body control unit 111 (see FIG. 6). For example, the sensor receiving unit 201, the engine control unit 202, the operation panel control unit 203, the system control unit 204, the setting analysis unit 207, and the QR code analysis unit 206 are all realized by software in the main body control unit 111. May be implemented entirely in hardware (circuitry), partially in software, and the rest in hardware (circuitry). Also good. The read data storage unit 205 may be realized by a volatile semiconductor memory in the main body control unit 111 or may be realized by a non-volatile semiconductor memory. The default setting recording unit 208 may be realized by a non-volatile semiconductor memory in the main body control unit 111 or may be realized by a non-volatile storage device (HDD or the like).

  When the sensor receiving unit 201 detects a detection target (for example, the document 300) by a sensor such as various sensors (for example, the document set sensor 58 or the manual feed detection sensor 74 shown in FIG. 2), the system control unit 204 is notified.

  The operation panel control unit 203 notifies the system control unit 204 of a command input via the operation panel 150a.

  The system control unit 204 comprehensively controls each unit of the image processing apparatus 1 based on the detection result notified from the sensor reception unit 201 and the command notified from the operation panel control unit 203. The system control unit 204 instructs the engine control unit 202 based on a command notified from the operation panel control unit 203. The system control unit 204 includes a processing unit 204a.

  The engine control unit 202 controls the engine (the image processing hardware included in the main body control unit 111) according to the instruction received from the system control unit 204, and reads the image of the document 300. The read image is held by the engine control unit 202 and is stored in the read data storage unit 205 by the engine control unit 202 as necessary.

  The engine control unit 202 includes a first acquisition unit 202a and a second acquisition unit 202b. The first acquisition unit 202 a acquires an image of the document 300 that is transported through the reverse transport path (first transport path) 52. The second acquisition unit 202 b acquires an image of the document 300 that is transported through the straight transport path (second transport path) 60.

  For example, the image of the original 300 read by the optical scanning units 47 and 69 is held by the engine control unit 202. When the engine control unit 202 receives a detection signal from the document setting sensor 58 via the sensor reception unit 201 and the system control unit 204, the first acquisition unit 202a controls the engine according to the detection signal from the document setting sensor 58. An image of the document 300 held by the unit 202 is acquired. Alternatively, for example, when the engine control unit 202 receives a detection signal of the manual feed set detection sensor 74 via the sensor reception unit 201 and the system control unit 204, the second acquisition unit 202a detects the detection signal of the manual feed set detection sensor 74. In response to this, an image of the document 300 held by the engine control unit 202 is acquired.

  The read data storage unit 205 stores the image of the original 300 read by the engine control unit 202. The image is stored by the engine control unit 202, and the image is read by the engine control unit 202 and the QR code analysis unit 206.

  The QR code analysis unit 206 reads a QR code (registered trademark) image (code image) from the image data stored in the read data storage unit 205. For example, the QR code analysis unit 206 includes a determination unit 206a. The determination unit 206a reads the image data acquired by the second acquisition unit 202b from the data storage unit 205, and adds an QR code (registered trademark) image (code) to the image acquired by the second acquisition unit 202b. Image) is included. The QR code analysis unit 206 decodes the QR code (registered trademark) when the image acquired by the second acquisition unit 202b includes an image (code image) of the QR code (registered trademark). Restore the information described in (registered trademark). The QR code analysis unit 206 notifies the setting analysis unit 207 of information described in the QR code (registered trademark) (information included in the code image).

  The setting analysis unit 207 can recognize that the QR code (registered trademark) has been detected when the information described in the QR code (registered trademark) is notified from the QR code analysis unit 206. For example, the setting analysis unit 207 includes a specifying unit 207a. The specifying unit 207a specifies the setting indicated in the code image based on information described in the QR code (registered trademark). For example, if the specifying unit 207a can recognize that the setting content of the image reading process is included in the information described in the QR code (registered trademark), the recognized setting content is set as the specified setting. be able to. Alternatively, for example, the specifying unit 207a has a table indicating the correspondence between the identification information of the setting content and the setting content for a plurality of types of settings in advance, and the setting content is included in the information described in the QR code (registered trademark). If it can be recognized that the identification information is included, the setting content corresponding to the recognized identification information can be specified from the table. The setting analysis unit 207 notifies the system control unit 204 of the setting indicated by the QR code (registered trademark). The setting analysis unit 207 cannot detect the QR code (registered trademark) (for example, when the QR code (registered trademark) causes a decoding error) or the content of the QR code (registered trademark) is not the setting information. In this case, the default setting is acquired from the default setting recording unit 208 and the default setting is notified.

  The default setting recording unit 208 stores default settings for reading processing in advance.

  For example, when the document 300 to be read includes the paper 301 shown in FIG. 8A and the clear file 302 shown in FIG. 8B, the document 300 can be configured with the paper 301 sandwiched between the clear files 302. . FIG. 8A is a diagram illustrating the configuration of the paper 301. FIG. 8B is a diagram illustrating the configuration of the clear file 302. In the clear file 302, QR codes (registered trademarks) 302a and 302b are arranged at positions to be outside the paper 301 with the paper 301 being sandwiched. For example, on the surface of the clear file 302, a QR code (surface QR code) 302 a shown in FIG. On the back side of the clear file 302, a QR code (back side QR code) 302b shown in FIG. 8D is arranged at a position that should be outside the paper 301 and corresponding to the QR code (registered trademark) 302a. . The QR codes (registered trademarks) 302a and 302b may be printed on the clear file 302 or may be pasted in the form of a sticker or the like.

As shown in FIG. 8C and FIG. 8D, the document 300 can be configured by sandwiching the paper 301 between the clear files 302 in which the QR codes (registered trademarks) 302a and 302b are arranged. By inserting the document 300 into the second paper feed port 72 (see FIG. 5B), the image processing apparatus 1 reads (scans) the document 300 from above the clear file 302 and stores it in the clear file 302. The distributed QR codes (registered trademark) 302a and 302b are read. The processing unit 204a of the system control unit 204 executes processing (reading processing) of the scanned image in accordance with the contents of the setting (first setting) stored in the QR codes (registered trademark) 302a and 302b. In the QR code (registered trademark) 302a and 302b, for example, settings in a table format as shown in Table 1 below can be stored.

When reading by the image processing apparatus 1 is executed with this setting, the processing unit 204a stores an image file as shown in FIG. 8E in the share folder of the user A. FIG. 8E is a diagram illustrating image data that has been read with the settings described in the QR codes (registered trademark) 302a and 302b. If the QR code (registered trademark) cannot be detected in the read original 300, the processing unit 204a of the system control unit 204 executes a reading process according to a preset default setting (third setting). . The default setting can be set in a table format as shown in Table 2 below, for example.

  When the reading process by the processing unit 204a is executed with this setting, the A4 aggregated duplex monochrome copy process is performed.

  In the example illustrated in FIG. 8, a case where the document 300 in which the paper 301 is sandwiched between the clear files 302 on which the QR codes (registered trademarks) 302 a and 302 b are printed is inserted into the second paper feed port 72 is illustrated. However, the document 300 including the paper 301 on which the QR code (registered trademark) is printed may be inserted into the second paper feed port 72. In that case, the processing unit 204a can perform the reading process according to the settings included in the QR code (registered trademark) printed on the paper 301.

  When the original 300 is inserted into the first paper feed port 59, the processing unit 204a does not start reading the original 300 immediately, but presses the read start button from the operation panel 150a (see FIG. 6). Reading may not be performed until a signal indicating is received. When the original 300 is read by inserting the original 300 from the first paper feed port 59, the processing unit 204a sets the setting (second setting) set on the operation panel 150a (see FIG. 6). ), Even if a QR code (registered trademark) is printed on the original 300, the content of the QR code (registered trademark) may not be set as a setting.

  Next, the operation of the image processing apparatus 1 will be described with reference to FIG. FIG. 9 is a flowchart showing the operation of the image processing apparatus 1.

  When the image processing apparatus 1 detects that the document 300 is inserted into the second paper feed port 72 (Yes in S1), the image processing apparatus 1 starts reading the document 300 (S2). In other words, the image processing apparatus 1 acquires an image of the document 300 conveyed through the straight conveyance path 60 (second acquisition step). The image processing apparatus 1 reads the acquired image of the original 300 and saves it in the data storage unit 205 (see FIG. 7), tries to detect a QR code (registered trademark) from the saved image (S3), and the QR code. It is determined whether (registered trademark) has been detected (S4).

  For example, the image processing apparatus 1 has a QR code (registered trademark) template image, and by performing template matching using the template image, the entire image of the surface of the document 300 (see FIG. 8C) is obtained. The image of the QR code (surface QR code) 302a can be cut out as a partial image (first partial image data). Further, the image processing apparatus 1 has a QR code (registered trademark) template image, and by performing template matching using the template image, the entire image of the back side of the document 300 (see FIG. 8D) is obtained. The image of the QR code (back QR code) 302b can be cut out as a partial image (second partial image data). The image processing apparatus 1 can determine that the QR code (registered trademark) has been detected when at least one of the front surface QR code 302a and the rear surface QR code 302b can be cut out as a partial image. When none of the codes 302b can be cut out, it can be determined that the QR code (registered trademark) cannot be detected.

  The image processing apparatus 1 can detect the QR code (registered trademark) from the image of the document 300 (Yes in S4), and the content decoded from the QR code (registered trademark) is the setting information (Yes in S5). Then, a job is constructed from the settings included in the QR code (registered trademark) (S6). At this time, for example, when both the front QR code 302a and the back QR code 302b can be cut out as partial images, the image processing apparatus 1 selects one QR code (registered trademark) from the front QR code 302a and the back QR code 302b. The settings included in the QR code (registered trademark) may be arbitrarily selected and specified. Alternatively, for example, the image processing apparatus 1 assigns priorities to the front surface QR code 302a and the back surface QR code 302b in advance, and specifies settings included in the QR code (registered trademark) selected according to the priorities. May be. Then, the image processing apparatus 1 performs an image reading process with the specified setting (S8). That is, the image processing apparatus 1 processes the image acquired in S2 (second acquisition step) according to the settings included in the QR code (registered trademark) (first processing step).

  When the image processing apparatus 1 cannot detect the QR code (registered trademark) from the image of the document 300 (No in S4), or the information included in the QR code (registered trademark) is not the setting information (in S5). No) builds a job from the default settings (S7). If it is necessary to read the original 300 in executing the job, the image of the original 300 that has already been read and stored can be handled as a read image, and the job can be executed. For example, the image processing apparatus 1 performs an image reading process with the default settings acquired from the default setting recording unit 208 (see FIG. 7) (S8).

  The image processing apparatus 1 has not detected that the document 300 has been inserted into the second sheet feed port 72 (No in S1), and has detected that the document 300 has been inserted into the first sheet feed port 59. If not (No in S9), the process returns to S1.

  The image processing apparatus 1 has not detected that the document 300 has been inserted into the second sheet feed port 72 (No in S1), and has detected that the document 300 has been inserted into the first sheet feed port 59. If yes (Yes in S9), nothing is done at that time, and the process waits until there is an input from the operation panel (No in S10). When there is an input from the operation panel (Yes in S10), the image processing apparatus 1 constructs a job according to the setting input from the operation panel (S11). If it is necessary to read the original 300 in executing the job, the original 300 is read from the first paper feed port 59 and the job is executed (S12). That is, the image processing apparatus 1 acquires an image of the document 300 conveyed through the reverse conveyance path 52 (first acquisition step), and processes the acquired image according to the setting input in S10 (second process). Step).

  Next, a sequence when the original 300 is inserted from the second paper feed port 72 and the reading process is executed will be described with reference to FIG. FIG. 10 is a sequence diagram illustrating the operation of the image processing apparatus 1.

  When the sensor detects that the document 300 has been inserted into the second paper feed port 72, the sensor receiving unit 201 notifies the system control unit 204 that the document 300 has been inserted into the second paper feed port 72. (S21).

  The system control unit 204 that has received the notification of the insertion of the document 300 supplies a reading start instruction for starting the reading of the inserted document 300 to the engine control unit 202 (S22).

  In response to the reading start instruction, the engine control unit 202 executes reading, and stores the read data of the original 300 in the read data storage unit 205 (S23). When the data accumulation is completed, the engine control unit 202 supplies a read completion notification to the system control unit 204 (S24).

  Receiving the read completion notification, the system control unit 204 supplies a setting analysis instruction for analyzing the setting included in the QR code (registered trademark) to the setting analysis unit 207 (S25).

  Upon receiving the setting analysis instruction, the setting analysis unit 207 receives a QR code analysis instruction for analyzing the QR code (registered trademark) in order to know the content of the QR code (registered trademark) read from the document 300. (S26).

  Upon receiving the QR code analysis instruction, the QR code analysis unit 206 performs reading processing (image processing) on the read original 300 from the reading data storage unit 205 (S27), and detects a QR code (registered trademark) from the read image. (S28). The QR code analysis unit 206 analyzes the detected QR code (registered trademark), and sends information stored in the QR code (registered trademark) to the setting analysis unit 207 as QR code analysis information.

  Receiving the QR code analysis information, the setting analysis unit 207 attempts to convert the analysis information of the QR code (registered trademark) into the setting in order to obtain the setting from the analysis information of the QR code (registered trademark) (S29). At this time, if the content described in the QR code (registered trademark) is not a table showing the setting (for example, the table shown in Table 1), or the QR code (registered trademark) can be detected from the image. If the setting cannot be obtained from the QR code (registered trademark), such as when there is no such information, the default setting recording unit 208 is accessed (S30), and the default setting is obtained (S31). That is, the default setting registered in advance from the default setting recording unit 208 is acquired. Thereafter, the setting analysis unit 207 notifies the system control unit 204 of the setting if the setting can be acquired from the QR code (registered trademark), and the default setting otherwise, as setting information (S32).

  Based on the received setting information, the system control unit 204 performs job construction (S33) and job execution (S34). At this time, when the content of the job includes reading of the document 300, the system control unit 204 reads from the read data storage unit 205 as image reading and does not instruct the engine control unit 202 to read. For example, when constructing a job from the settings shown in Table 2, the system control unit 204 converts “<1> images of the front and back originals 300 stored in the read data storage unit 205 into a monochrome output format image”. <2> Rotate each image on the front and back surfaces arranged in RAM by 90 degrees, reduce to half size, and create an aggregate image <3> Output the created aggregate image to a plotter " Build (S35).

  Next, a sequence when the original 300 is inserted from the first paper supply port 59 and the reading process is executed will be described with reference to FIG. FIG. 11 is a sequence diagram illustrating the operation of the image processing apparatus 1.

  When the document set sensor 58 detects that the document 300 is inserted into the first paper feed port 59, the sensor receiving unit 201 supplies a document insertion notification to the system control unit 204 (S41). Even when the system control unit 204 receives a notification that the original 300 is inserted into the first paper feed port 59, the system control unit 204 does not issue a reading start instruction and waits for an input notification from the operation panel control unit 203.

  For example, the user selects to copy the A4 size original 300 to the original 300 on the original tray 51 in monochrome, and presses the copy button, thereby inputting a reading setting instruction and an original reading start instruction from the operation panel. . When there is an input notification (for example, notification of a reading setting instruction and a document reading start instruction) from the operation panel control unit 203 (S42), system control is performed to extract setting information from the input (for example, a reading setting instruction). The unit 204 issues a setting analysis instruction corresponding to the reading setting instruction to the setting analysis unit 207 (S43).

  Upon receiving the setting analysis instruction, the setting analysis unit 207 extracts setting information from the input content and notifies the system control unit 204 of the setting information (S44). The system control unit 204 that has received the setting information performs job construction (S45) and job execution (S46) according to the setting. At this time, when the reading of the document 300 is included in the job contents, a reading start instruction is notified to the engine control unit 202 (S47), and the document 300 is read. For example, when a job is constructed from the settings in Table 2, “<1> read both sides of the original 300 from the first paper feed port 59 in a monochrome output image format, and place the read image in the RAM <2 > Rotate each image on the front and back surfaces arranged in the RAM by 90 degrees, reduce the image to a half size, and create an aggregated image. <3> Output the created aggregated image to a plotter ”. When the reading process of the document 300 is completed, the engine control unit 202 supplies a reading completion notification to the system control unit 204 (S48).

  As described above, in the embodiment, the image processing apparatus 1 performs the image reading process on the document 300 inserted into the first sheet feeding port 59 with the setting accepted by the operation panel, and the second process. An image reading process is performed on the original 300 inserted into the paper feeding port 72 with the setting indicated by the QR code (registered trademark). Accordingly, when reading processing with the setting accepted on the operation panel is desired, the original 300 is inserted into the first paper feed port 59, and reading processing with the setting indicated by the QR code (registered trademark) is desired. By inserting the original into the second paper feed port 72, the setting can be appropriately selected in the image processing apparatus 1.

  The code that should include the processing setting may be another two-dimensional code (for example, CP code (registered trademark)) instead of the QR code (registered trademark) or a one-dimensional code (for example, barcode). ).

  In S4 of FIG. 9, it is determined that the QR code (registered trademark) can be detected when at least one of the front surface QR code 302a and the rear surface QR code 302b can be cut out as a partial image. The conditions for determining that it has been detected may be made stricter.

  For example, the image processing apparatus 1 acquires an image (partial image) 302a1 of the front QR code 302a and an image (partial image) 302b1 of the back QR code 302b as shown in FIGS. 12 (a) and 12 (b). To do. The image processing apparatus 1 generates an image 302b11 obtained by horizontally inverting the image 302b1 of the back surface QR code 302b, and compares the image 302a1 of the front surface QR code 302a with the image 302b11 of the back surface QR code 302b horizontally reversed. Determine whether they match. For example, the image processing apparatus 1 may perform image comparison on a pixel-by-pixel basis and determine whether or not both images match depending on whether or not the ratio of the number of pixels with the same luminance level in the total number of pixels exceeds a threshold value. it can. Alternatively, for example, the image processing apparatus 1 can determine whether or not the two images match using another arbitrary image comparison algorithm. As shown in FIG. 12A, the image processing apparatus 1 can detect a QR code (registered trademark) when an image 302a1 of the front surface QR code 302a and a horizontally reversed image 302b11 of the back surface QR code 302b match. Can be judged. In addition, as shown in FIG. 12B, the image processing apparatus 1 determines that the QR code (registered trademark) is displayed when the image 302a1 of the front surface QR code 302a and the horizontally reversed image 302b11 of the back surface QR code 302b1 do not match. It can be determined that it could not be detected.

  Thus, for example, when a document 300 is configured in which a paper 301 printed with another QR code (registered trademark) is sandwiched between clear files 302 in which QR codes (registered trademark) 302a and 302b are arranged, QR codes (registered trademark) 302 a and 302 b arranged on the clear file 302 can be processed with priority.

  Further, when comparing the image of the front QR code 302a and the reverse image of the back QR code 302b, image comparison is performed not on the entire image but on a part of the image (for example, the lower half area). May be.

  For example, as shown in FIG. 13A, when the QR code (back QR code) 302b arranged on the clear file 302 and the paper 301 in the clear file 302 overlap, they match. There is a possibility that the image of the front surface QR code 302a to be determined to be inconsistent with the horizontally reversed image of the back surface QR code 302b. Even in this case, as shown in FIG. 13B, the comparison between the image of the front surface QR code 302a and the reverse image of the rear surface QR code 302b is performed on a part of the image (for example, the lower half region). By doing so, it is possible to avoid an inappropriate determination that the images that should be determined to be consistent do not match.

  Next, a hardware configuration of a device to which the image processing apparatus 1 is applied will be described with reference to FIG. FIG. 14 is a diagram illustrating a hardware configuration of a device to which the image processing apparatus 1 is applied.
