  In the image reading apparatus capable of determining the authenticity of the original, when the original is determined to be a foreign object, the image reading and the magnetic waveform reading of the original are interrupted and the subsequent original is not read, and the voice control unit or the display control unit In some cases, the operator is notified that it has been determined to be a freight. In such a case, when the operator receives a warning, the operator verifies the authenticity of the original by visual inspection. However, for example, a document conveyed obliquely does not correctly pass through the watermark detection unit, infrared detection unit, and ultraviolet detection unit in which the watermark unit, infrared reaction unit, and ultraviolet reaction unit are arranged in the conveyance path. In some cases, it is not possible to detect all of them normally, and even a real product may be erroneously determined as a fake. In such a case, even a genuine document is interrupted, and the operator must place the document again on the document placement unit and perform a process of reading it again, resulting in a reduction in work efficiency. Further, in an image reading apparatus having only one paper discharge unit, a document that is determined to be genuine and a document that is determined to be genuine are discharged from the same paper discharge unit. There was a risk that the manuscript that was determined to be a fiction would be mixed.

  SUMMARY OF THE INVENTION In view of the above-described circumstances, the present invention provides an image reading apparatus, an original authenticity determining apparatus, and an original authenticity determining method that can efficiently specify a document original.

The present invention has been invented in order to solve the above-described problems, and includes a reading unit for reading an image of a document conveyed on a conveyance path, an authenticity determination unit for determining the authenticity of the document, and the document. In the image reading apparatus having a paper discharge unit for discharging, the paper discharge operation is stopped in a state where the original is held in the paper discharge unit when the authenticity determination unit determines that the original is a foreign object. .
The document authenticity determination apparatus according to the present invention includes a transport unit that transports a document along a transport path, an authenticity determination unit that determines the authenticity of a document transported along the transport path, and the transport path. A document discharge unit that discharges the document, and the document document that has been determined to be a sample by the authenticity determination unit is not discharged from the discharge unit, but remains in the discharge unit.
Further, according to the document authenticity determination method of the present invention, the authenticity of the original conveyed along the conveyance path is determined by the authenticity determination unit, and the original that has been determined to be a false by the defect determination unit is discharged without being discharged. It is characterized by staying in the department.
In the present invention, when a succeeding document following the original document is being fed, it is preferable to return the succeeding document to the feeding unit.

  When the image reading device erroneously determines the authenticity of the original due to fluctuations in the feeding state of the original and determines that the original is a genuine article, the original judged to be a foreign object is mixed into the bundle of originals ejected from the paper ejection unit. In addition, there is no risk of erroneous processing, and the accuracy of work can be improved. In addition, when a document detection unit is provided in the sheet discharge unit and the document is stopped by the sheet discharge unit, when the document detection unit no longer detects the document, the image data read from the document is processed. In this case, it is possible to shift to the next document reading process without re-reading the image of the document, leading to improvement in work efficiency.

Embodiments of the present invention exemplified below will be described with reference to the drawings.
<Example 1>

  FIG. 4 is a perspective view of the image reading apparatus 1. The image reading apparatus 1 is provided with a document placing portion 2 for placing a document and a conveyance path (not shown) for conveying the document. Further, the image reading apparatus 1 includes a paper discharge stacking unit 3 on which a document is discharged. FIG. 1 is a block diagram of the image reading apparatus 1. The image reading apparatus 1 includes a CPU 80 that controls the operation of each unit of the image reading apparatus, a magnetic information reading unit 81 that reads magnetic information from the original 90, a watermark detection unit 82 that detects the presence or absence of a watermark on the original 90, and an original An infrared detection unit 83 that detects the presence or absence of an infrared reaction unit on 90, and an ultraviolet detection unit 84 that detects the presence or absence of an ultraviolet reaction unit on document 90. Further, the image forming apparatus includes an authenticity determining unit 85 that determines the authenticity of the document 90 based on the results detected by the watermark detecting unit 82, the infrared detecting unit 83, and the ultraviolet detecting unit 84, and an image reading unit 86 that reads image information. Yes. The various detection units and various reading units may be configured by hardware, or may be configured by a combination of hardware and software.

  FIG. 13 is a diagram illustrating a manuscript 90 printed magnetically. Near the lower end of the original 90, a MICR character 91 called MICR that enables magnetic ink character recognition is printed. As illustrated in FIG. 14, it is assumed that an ultraviolet reaction unit 92, a watermark unit 93, and an infrared reaction unit 94 are arranged on the document 90. FIG. 5 is a cross-sectional view illustrating a schematic configuration of the image reading apparatus 1. The originals 90 placed on the original placing unit 2 are fed one by one to the conveyance path 6 by the feeding roller 4 and the separation roller 5 while preventing double feeding. In the conveyance path 6, the document detection sensor 7, the watermark detection unit 8 that detects the presence / absence of the watermark portion 93 of the document 90, the infrared detection unit 9 for detecting the presence / absence of the infrared reaction unit 94 of the document 90, An ultraviolet ray detection unit 10 for detecting the presence or absence of the ultraviolet ray reaction unit 92, a magnetic information reading unit 11 for reading the MICR character 91, and an image information reading unit 12 for reading an image of a document are provided. Further, the conveyance roller 13a that conveys the document to the conveyance path and the sheet discharge roller 13b that discharges the document provided in the vicinity of the sheet discharge port are one of the members constituting the sheet discharge unit. As illustrated in FIG. 6, the image reading apparatus 1 is connected to a host computer 20 that is an example of an external apparatus via a communication cable 21.

  FIG. 2 illustrates a flowchart for explaining the processing of the present invention. Hereinafter, description will be made with reference to the flowchart of FIG. The image reading apparatus 1 starts this processing when receiving an image reading instruction from the host computer 20 via the communication cable 21, but may be started by operating an operation unit (not shown) provided in the image reading apparatus 1. First, it is confirmed by using a sensor (not shown) whether or not the document 90 is placed on the document placement unit 2. After confirming the placement of the document 90, the document roller 90 and the separation roller 5 feed the document 90 one by one to the transport path and transport it by the transport roller 13a so as not to be overlapped from the placed document bundle. . At this time, when it is detected that the document has passed through the document detection sensor 7, the image reading apparatus 1 measures and reads various information in steps S501 to S505 described later with reference to FIG. Is started (step S101).

  FIG. 3 is a flowchart illustrating details of various information reading processing in step S101. If the distance between the document detection sensor 7 and the watermark detection unit 8 is L1, and the conveyance speed of the document 90 is v, the document 90 reaches the watermark detection unit 8 after L1 / v from the document detection. Therefore, the detection of the presence or absence of the watermark portion 93 on the original 90 is started after a lapse of L1 / v from the time when the leading edge of the original 90 passes the original detection sensor 7 (step S501).

  When the distance between the document detection sensor 7 and the infrared detection unit 9 is L2 and the conveyance speed of the document 90 is v, the document 90 reaches the infrared detection unit 9 after L2 / v from the document detection. Therefore, the time is measured using a timer (not shown), and after the lapse of L2 / v from the time when the document detection sensor 7 has passed through the leading edge of the document 90, the above-described infrared reaction unit 94 on the document 90 is detected. Detection of presence / absence is started (step S502).

  Further, if the distance between the original detection sensor 7 and the ultraviolet ray detection unit 10 is L3 and the conveyance speed of the original 90 is v, the original 90 reaches the ultraviolet ray detection unit L3 / v after the original detection. Therefore, the time is measured using a timer (not shown), and after the lapse of L3 / v from the time when the document detection sensor 7 passes the leading edge of the document 90, the above-described ultraviolet reaction unit 92 on the document 90 is detected. Detection of presence / absence is started (step S503).

  When the distance between the document detection sensor 7 and the magnetic information reading unit 11 is L4 and the conveyance speed of the document 90 is v, the document 90 reaches the magnetic information reading unit 11 after L4 / v from the document detection. Accordingly, the time is measured using a timer (not shown), and the above-mentioned MICR printed on the lower end of the original 90 after the elapse of L4 / v from the time when the original detection sensor 7 passes the leading edge of the original 90. Reading of the character 91 is started (step S504).

  Further, if the distance between the document detection sensor 7 and the image reading unit 12 is L5, the document 90 reaches the image reading unit 12 after L5 / v from the document detection. Measurement is performed, and image reading is started after a lapse of time L5 / v from the time when the document detection sensor 7 passes the leading edge of the document 90 (step S505). Note that the process of reading various information started in steps S501 to S505 is preferably performed in parallel, but may be configured to be sequentially executed. After the reading / detection of various types of information is completed, this process is terminated, and the process proceeds to step S102 in FIG. If reading / detection of various information is not completed due to failure in reading / detecting various information or the absence of various information, the reading / detection of various information is terminated after a predetermined upper limit time has elapsed. Is desirable.

  After completion of the detection and reading of various information, the image reading apparatus 1 determines based on the detection result of the presence / absence of the watermark part, the detection result of the presence / absence of the infrared reaction part, and the detection result of the presence / absence of the ultraviolet reaction part in step S102 of FIG. In addition, the authenticity determination unit 85 in FIG. In step S103, if it is determined that the conveyed original 90 is authentic as a result of the authenticity determination, the image reading apparatus 1 continues the conveyance of the original 90, and discharges the original onto the paper discharge stacking unit 3 in step S104. This process ends.

  On the other hand, as a result of the authenticity determination in step S103, if it is determined that the conveyed document 90 is a foreign object, the following processing is performed. That is, if the distance between the original detection sensor 7 and the paper discharge roller 13b is L6 and the conveyance speed of the original 90 is v, the original 90 reaches the discharge roller 13b after L6 / v from the original detection. Accordingly, while the time is measured using a timer (not shown) in step S105, the trailing edge of the document 90 is discharged after the time required for the leading edge of the document 90 to pass the discharge roller 13b has elapsed. Before passing through the roller 13b, the transport roller 13a and the paper discharge roller 13b are stopped to stop the paper discharge operation. Then, it notifies the host computer 20 that the conveyed document 90 has been determined to be an article, and ends this processing. In this way, since the document determined to be a jar is stopped while being nipped in the paper discharge unit, the document determined to be a jar is not mixed with the discharged document that is determined to be a real one. Post-processing can be easily performed.

<Example 2>
A second embodiment according to the present invention will be specifically described below with reference to the drawings.

  FIG. 7 shows a configuration diagram of the image reading apparatus 1a of the present embodiment. The difference from the image reading apparatus 1 of the first embodiment is that a second document detection sensor 15 which is a part of the document detection unit is provided in the vicinity of the paper discharge port. The second document detection sensor may be arranged on the upstream side of the conveyance path with respect to the paper discharge roller 13b as shown in FIG. 8, or may be arranged on the downstream side as shown in FIG. The first document detection sensor 14 has a function equivalent to that of the document detection sensor 7 of the first embodiment, and is arranged at the same position. The second document detection sensor constitutes a document detection unit together with the CPU 80 to which the output signal is input or hardware (not shown).

  FIG. 10 illustrates a flowchart for explaining the processing of the present invention. Hereinafter, description will be made with reference to the flowchart of FIG. When the image reading apparatus 1 receives an image reading instruction from the host computer 20 via the communication cable 21, the image reading apparatus 1 starts this processing, and after confirming that the original 90 is placed on the original placing portion 2, When it is detected by the roller 4 and the separation roller 5 that the document 90 is fed one by one to the conveyance path so as not to be fed from the document bundle, and is conveyed by the conveyance roller 13a and passed through the first document detection sensor 14, Various information reading / detection of S501 to S505 described in FIG. 3 is performed (step S201).

  Regarding the detection of presence / absence of the watermark portion 93, detection of the presence / absence of the infrared reaction portion 94, detection of the presence / absence of the ultraviolet reaction portion 92, reading of the MICR character 91, and image reading performed in the reading / detection of various information in step S201, Except that the document detection sensor 7 is replaced with the document detection sensor 14 in this embodiment, the description is omitted because it is the same as the description in the first embodiment.

  In step S202, the image reading apparatus 1 makes a determination by the authenticity determination unit 85 based on the detection result of the presence / absence of the watermark part, the detection result of the presence / absence of the infrared reaction part, and the detection result of the presence / absence of the ultraviolet reaction part acquired in step S201. I do. As a result of the authenticity determination, the image reading apparatus 1 continues the conveyance of the original 90 when the conveyed original 90 is determined to be authentic (YES in step S203), and connects the communication cable 21 to the host computer 20 for the read image information. And the document is discharged to the paper discharge stacking unit 3 to complete the present process. On the other hand, as a result of the authenticity determination, if it is determined that the conveyed document 90 is a bowl (NO in step S203), the image reading apparatus 1 proceeds to the bowl process illustrated in FIG. 11 (step S205).

  FIG. 11 is a flowchart exemplifying the procedure of the waste processing. When shifting to the saddle processing, the image reading apparatus 1 determines that the distance between the first document detection sensor 14 and the paper discharge roller 13b is L6 and the conveyance speed of the document 90 is v, and the leading edge of the conveyed document 90 is the first document detection. The original 90 reaches the paper discharge roller 13b after L6 / v from the time when it passes the sensor 14. Therefore, a timer (not shown) is used to measure the time, and after the time required for the leading edge of the document 90 to pass the paper discharge roller 13b has elapsed, the trailing edge of the document 90 causes the second document detection sensor 15 to pass. Before passing, the transport roller 13a and the paper discharge roller 13b are stopped to stop the paper discharge operation (step S301).

  Here, the detection result of the second document detection sensor 15 may be used in order to take a timing for stopping the paper discharge operation. That is, for example, when the second document detection sensor 15 is installed at a position upstream of the discharge roller 13b by a distance L7 and the conveyance speed of the document 90 is v, the detection time of the second document detection sensor 15 is detected. The document 90 reaches the paper discharge roller 13b after a lapse of L7 / v. Therefore, time is measured using a timer (not shown), and after the time when the leading edge of the document 90 passes the paper discharge roller 13b and before the time when the rear end of the document 90 finishes passing the paper discharge roller 13b. The paper discharge operation should be stopped. The conveyance may be stopped before the second document detection sensor 15 is passed. Alternatively, the paper discharge operation may be stopped immediately after detecting that the trailing edge of the document 90 has passed through the second document detection sensor 15.

  In step S <b> 302, the image reading apparatus 1 notifies the host computer 20 via the communication cable 21 of the determination result that the document is a bowl. Note that the notification is intended to inform the operator that it has been determined to be an article, so the image reading apparatus itself may notify the operator with a buzzer (not shown) without notifying the host computer 20. It doesn't matter. In step S303, the image reading apparatus 1 waits until an input operation instructing post-processing is performed by the operator confirming whether or not the determined authenticity determination result is correct. In addition, since it is necessary for the operator to confirm whether or not the determination result of the image reading apparatus 1 is correct by visual inspection of the original, the arrangement of the watermark portion, the infrared reaction portion, and the ultraviolet reaction portion on the original is considered. It is desirable that the image reading apparatus 1 stops the original 90 at a position where these are exposed from the paper discharge port and are easily viewed by the operator.

  Upon receiving any instruction from the operator via the host computer 20 or from an operation unit (not shown) provided in the image reading apparatus itself, the image reading apparatus 1 confirms the instruction content of the operator in step S304. If the operator determines that the document is genuine and has been instructed to process the acquired various data as valid data (YES in step S304), the host computer 20 is connected via the communication cable 21 in step S305. The image data is transferred to finish the freight processing. On the other hand, if the operator determines that the document is a fake, and the operator instructs to process the acquired various data as invalid data (NO in step S304), the image data read in step S306 is read. Discard and finish the freight processing.

  Returning to FIG. 10, the image reading apparatus 1 that has performed the filing process ends a series of processes.

<Example 3>
As a modification of the third embodiment, different forms of the filing process that can further save the operator's trouble will be described with reference to the drawings. FIG. 12 exemplifies a flowchart of another form of freight processing. When the image reading apparatus 1 determines that the conveyed document is a bowl depending on the presence of the watermark section, the infrared reaction section, and the ultraviolet reaction section, the bowl processing is started in step S401.

  Assuming that the distance between the first document detection sensor 14 and the paper discharge roller 13b is L6 and the conveyance speed of the document 90 is v, L6 / v after the leading edge of the conveyed document 90 passes through the first document detection sensor 14. The original 90 reaches the paper discharge roller 13b. Therefore, the image reading apparatus 1 measures time using a timer (not shown), and after the time required for the leading edge of the document 90 to pass through the paper discharge roller 13b has elapsed, the trailing edge of the document 90 is the second. Before passing through the document detection sensor 15, the transport roller 13a and the paper discharge roller 13b are stopped to stop the paper discharge operation (step S401).

  Here, the detection result of the second document detection sensor 15 may be used in order to take a timing to stop the paper discharge operation. That is, for example, when the second document detection sensor 15 is installed at a position upstream of the discharge roller 13b by a distance L7, and the conveyance speed v of the document 90 is v, the detection time of the second document detection sensor 15 is detected. After the elapse of L7 / v, the leading edge of the document 90 reaches the paper discharge roller 13b. Therefore, a timer (not shown) is used to measure the time, and after the time when the leading edge of the document 90 passes the paper discharge roller 13b, the trailing edge of the document 90 passes the second document detection sensor 15 and the trailing edge of the document passes. The paper discharge operation is stopped until the end. The document stopped in this way is nipped by the paper discharge roller 13b as in the second embodiment. Further, it is necessary for the operator to check whether the determination result of the image reading apparatus 1 is correct by visual inspection of the document. Therefore, in consideration of the arrangement of the watermark portion, the infrared reaction portion, and the ultraviolet reaction portion on the document, the image reading apparatus 1 places the document 90 at a position where these are exposed from the paper discharge port and are easily viewed by the operator. It is desirable to stop it.

  In step S <b> 402, the image reading apparatus 1 notifies the host computer 20 via the communication cable 21 that the document is determined to be a jar. The purpose of this is to inform the operator that it has been determined that the object is a bag, and the host computer 20 is not notified, and the image reading apparatus itself may be notified by a buzzer (not shown).

  In the processing loop formed by step S403 and step S404, the image reading apparatus 1 waits until the operator gives an instruction on how to treat by visual work in response to the determination result determined to be a bowl. Here, a case will be described in which the operator visually confirms that the document is genuine and has been erroneously determined, and that the document is to be removed from the paper discharge port by the operator. That is, if the operator visually recognizes the original and pulls out the original as an erroneous determination of the image reading apparatus 1, the image reading apparatus 1 detected by the second original detection sensor 15 in step S403 detects that the original has been pulled out. However, in step S404, the image data is transferred to the host computer 20 via the communication cable 21 and the saddle processing is terminated.

  On the other hand, if it is not detected in step S403 that the document has been removed from the paper discharge port, the image reading apparatus 1 receives a discard instruction in step S405 from the operator that the document is a fake and the data is invalid. Find out if it is not. If no discard instruction has been received in step S405, the process returns to step S403. In step S405, if the image reading apparatus 1 has received a discard instruction, the image reading apparatus 1 discards the read image data in step S406, and the image reading apparatus 1 ends the saddle processing.

  With the above-described configuration, even if the image reading apparatus erroneously determines authenticity, the operator can visually check the document, and in addition, the operator can perform an operation that is incorrect and is genuine. When the person recognizes, the user can move to reading the next original by performing an operation of pulling out the original from the paper discharge port, and the reading operation can be continued. For this reason, it is possible to continuously execute the reading process of the original bundle without wasting the image data read up to now, and it is possible to save labor.

  Although the description has been made assuming that the manuscript is visually recognized as an original by the operator, the manuscript is pulled out from the paper discharge port. However, the operator may remove the manuscript when the operator visually recognizes it as a bowl. In that case, the control flow may be changed so as to wait until an invalid instruction by pulling out the document or a valid instruction by some other operation is received when it is determined that the object is a bowl.

  In each of the above-described examples (including Examples 4 and 5 described later), a feeding roller, a separation roller, a conveyance roller, and a paper discharge roller are used, but a feeding belt, a separation belt, a separation pad, a conveyance belt, It may be changed to a paper discharge belt or the like. In addition, part or all of the processing performed by the CPU in each embodiment may be realized by hardware. In addition, all or part of various processes including control, detection, and determination according to the present invention may be performed by an external device connected to the image reading apparatus by a cable, a network, wireless communication, electromagnetic wave communication, optical communication, or the like. In this case, a system including the image reading apparatus and the external device corresponds to the image reading apparatus of the present invention.

<Embodiment 4> A fourth embodiment according to the present invention will be specifically described below with reference to FIGS. FIG. 15 is a schematic configuration diagram showing a document conveyance state, and FIG. 16 is a flowchart for explaining the processing of the present invention. FIG. 17 is a flowchart illustrating the procedure of the freight processing. FIG. 18 is a view when the next original 90b has already been fed when the image reading apparatus 1 determines that the original 90a is an article. FIG. 19 is a diagram illustrating a state in which the image reading apparatus 1 has returned the next original 90 b to the paper feeding unit 2.

First, the description will be made with reference to the flowchart of FIG. 16, but FIGS. As shown in FIG. 6, the image reading apparatus 1 starts this processing when receiving an image reading instruction from the host computer 20 via the communication cable 21, but is operated by an operation unit (not shown) provided in the image reading apparatus 1. You may start. First, it is confirmed by using a sensor (not shown) whether or not the document 90 is placed on the document placement unit 2 shown in FIG. After confirming the placement of the original 90, the feed roller 4 and the separation roller 5 feed the original 90 one by one to the transport path so as not to be fed from the placed original bundle, and are transported by the transport roller 13a. To do. At this time, when it is detected that the document has passed through the document detection sensor 7, the image reading apparatus 1 starts reading / detecting various information in steps S501 to S505 using FIG. 3 while measuring time using a timer (not shown). (Step S601).

Here, FIG. 15 is a diagram illustrating a state in which the document 90a is fed to the conveyance path and reading / detection of various types of information is started in step S601. Detection of the presence / absence of the watermark portion 93, detection of the presence / absence of the infrared reaction portion 94, detection of the presence / absence of the ultraviolet reaction portion 92, reading of the MICR character 91, and image performed in the reading / detection of various information in step S601 shown in FIG. Reading is the same as that described in the second embodiment, and a description thereof is omitted here.

Next, in step S602, the image reading apparatus 1 is based on the detection result of the presence / absence of the watermark unit 93, the detection result of the presence / absence of the infrared reaction unit 94, and the detection result of the presence / absence of the ultraviolet reaction unit 92 acquired in step S601. Determination is performed by the authenticity determination unit 85. As a result of the authenticity determination (step S603), the image reading apparatus 1 continues the conveyance of the document 90 and determines the read image information to the host computer 20 when the conveyed document 90 is determined to be authentic (YES in step S604). The data is transferred via the communication cable 21, the original is discharged to the paper discharge stacking unit 3, and this processing is finished. In FIG. 16, steps S603 and S604 are illustrated separately for explanation, but may be a single authenticity determination step. On the other hand, as a result of the authenticity determination in step S603, when it is determined that the conveyed document 90 is a bowl (NO in step S604), the image reading apparatus 1 proceeds to the bowl process illustrated in FIG. 11 (step S605). .

Subsequently, FIG. 17 is a flowchart illustrating the procedure of the freight processing in step S605. When the image reading apparatus 1 proceeds to the container process in step S701, in step S702, the image reading apparatus 1 detects whether or not the next original 90b shown in FIG. 15 is fed. Here, FIG. 18 shows a diagram when the original reading apparatus 1 has already fed the next original 90b when it determines that the original 90a is a bowl. The image reading apparatus 1 that has detected that the next original 90b is being fed returns the next original 90b to the paper feed unit 2 in S703. Here, FIG. 19 shows a state in which the document reading apparatus 1 has returned the subsequent document 90b to the paper feed unit 2. At this time, if the transport unit that transports the document to the paper discharge unit 3 is configured by one drive source, the document 90a is also transported until the next document 90b is returned to the paper feed unit 2 as shown in FIG. It is sent back upstream in the path 6. The image reading apparatus 1 that has detected that the next original 90b has been returned to the paper feed unit 2 does not feed the next original 90b in step S704, as shown in FIG. 90 a is transported downstream in the transport path 6. Assuming that the second document detection sensor 15 is installed at a position upstream by a predetermined distance from the paper discharge roller 13b, and the conveyance speed of the document 90a is v, a predetermined distance from the detection time of the second document detection sensor 15. After the elapse of time, the original 90a reaches the paper discharge roller 13b. Therefore, the image reading apparatus 1 measures time using a timer (not shown), and after the time when the leading edge of the document 90a passes through the paper discharge roller 13b, the rear end of the document 90a passes through the paper discharge roller 13b. The paper discharge operation is stopped before the end point (step S705). Note that when the transport unit and the paper discharge unit can be controlled separately (for example, when configured with separate drive sources), the paper output unit does not discharge the original document, although not shown. On the other hand, it is possible to return the next succeeding document to the paper feed unit (feed unit) by the reverse feed control of the transport unit. As a result, it is possible to remove the original document from the paper discharge unit while the subsequent document is being fed back, so that the processing efficiency can be improved.

Then, it notifies the host computer 20 that the conveyed document 90 has been determined to be an article, and ends this processing. In this way, since the document determined to be a jar is stopped while being nipped in the paper discharge unit, the document determined to be a jar is not mixed with the discharged document that is determined to be a real one. The post-processing can be easily performed, and the processing of the next original 90b can be promptly resumed after the processing on the original 90a is finished.

<Example 5> A fifth embodiment according to the present invention will be specifically described below with reference to the drawings. FIG. 21 is a configuration diagram of an image reading apparatus according to this embodiment. The difference from the image reading apparatus 1 a of the second embodiment is that conveyance rollers 13 c and 13 e are provided in the conveyance path, and the conveyance roller 13 c is controlled by the same first conveyance unit as the conveyance roller 4. Further, the conveyance roller 13e is controlled by the same second conveyance unit as the paper discharge roller 13b. The first transport unit here is a part that performs transport operations other than the second transport unit that performs the paper discharge operation, and in the present embodiment, is the transport rollers 4, 13, and 13c. In the present embodiment, the second transport unit is a transport roller 13e and a paper discharge roller 13b. With such a configuration, the image reading apparatus 1a allows the next document 90b to be transported by the first transport unit even when the previous document 90a remains in the second transport path, and to perform image reading and reading / reading of various information. Detection processing can be performed, and processing efficiency can be improved.

The image reading apparatus 1a detects whether or not the previous document 90a has been discharged by the second transport unit (step S803).

In step S803, if the previous original 90a has already been discharged, the image reading apparatus 1a uses the conveyance roller 13c controlled by the first conveyance unit to reach the conveyance roller 13e controlled by the second conveyance unit. The original 90b is conveyed. (Step S806) On the other hand, when it is detected in step S803 that the previous document 90a has not been discharged to the paper discharge unit 3 as shown in FIG. 26, the image reading apparatus 1a has the leading edge of the document at the transport roller 13c. The first transport unit is stopped where the value does not exceed (step S804).

FIG. 27 is a diagram illustrating a state in which the image reading apparatus 1a stops the document 90b where it does not exceed the transport roller 13c because the previous document 90a is stopped at the paper discharge port. Then, the image reading apparatus 1a stands by until it is detected in step S805 that the previous original 90a has been discharged (step S805). In step S805, the image reading apparatus 1a that has detected that the previous original 90a has been discharged conveys the original 90b to the conveyance roller 13e by operating the conveyance roller 13c, thereby conveying the original 90b to the second conveyance unit. (Step S806). FIG. 28 is a diagram illustrating a state in which the image reading apparatus 1a resumes the conveyance of the document 90b. In step S807, the image reading device 1a determines whether the authenticity determination unit is based on the detection result of the presence / absence of the watermark unit 93, the detection result of the presence / absence of the infrared reaction unit 94, and the detection result of the presence / absence of the ultraviolet reaction unit 92 acquired in step S802. The determination is made according to 85. If the image reading apparatus 1a determines that the conveyed document 90b is genuine as a result of the authenticity determination (YES in step S808), the image reading apparatus 1a performs the genuine process illustrated in FIG. 23 in step S809.
