Description

  The present invention relates to an image reading apparatus that reads an image from a placed document and transmits the read image to a terminal via a network. The present invention also relates to an image reading system including an image reading apparatus and a terminal connected via a network.

An image reading apparatus that transmits an image read from a document to a terminal via a network is known. As a method for controlling such an image reading apparatus, there is a method called a pull scan method. In this method, an image reading apparatus is controlled from a terminal via a network.
In the case of the pull scan method, the user needs to return to the terminal after placing the document on the image reading apparatus and transmit a start command to start the image reading by operating the terminal. For this reason, there is a possibility that another person mistakenly or intentionally replaces the placed document after placing the document and operating the terminal.
Patent Document 1 proposes an image reading apparatus that is not connected to a network but detects that a document is replaced. This image reading apparatus includes a wireless tag reader, and reads tag information from a wireless tag attached to a document at an image reading position. Read tag information repeatedly. Changes in the tag information read repeatedly are monitored between the start and end of the document reading operation. This image reading apparatus detects that a document has been replaced by detecting a change in tag information.

JP 2006-109378 A

The image reading apparatus disclosed in Patent Document 1 monitors changes in tag information read repeatedly between the start and end of a document reading operation. However, in the case of a pull scan type image reading apparatus, it takes a long time for the apparatus to start reading a document after the user places the document, and the document may be replaced during this time. Since the technique of Patent Document 1 is not premised on a pull-scan type image reading apparatus connected to a network, it cannot detect replacement of a document before starting reading. Further, the technique of Patent Document 1 cannot cope with an existing document that is not attached with a wireless tag.
The present invention has been created in view of the above problems, and is suitable for an image reading apparatus connected to a network and operating in a pull scan system, and can detect an unexpected document replacement by a user who placed a document. An object is to provide an image reading apparatus.

  The present invention can be embodied in an image reading apparatus that transmits an image read from a document to a terminal via a network. The image reading apparatus includes a placement unit, a document sensor, a receiving unit, and a monitoring unit. The placement unit is a unit for the user to place a document. The document sensor detects that the document is placed on the placement unit. The receiving unit receives an image reading start command from a terminal connected to the network. The monitoring unit notifies the detection of the new placement when a new placement of the document is detected between the time when the document sensor detects the placement of the document and the time when the reception unit receives the start command. Is transmitted to the transmission source terminal of the start command.

In this image reading apparatus, the user notifies the start command transmission source terminal (that is, the user) that the document has been replaced between the time when the document is placed and the time when the user returns to the terminal and transmits the read start command. can do.
Further, in this image reading apparatus, unlike the patent document 1, it is not necessary to attach a wireless tag to a document.
The document sensor may be, for example, an optical sensor that includes a light emitting unit and a light receiving unit, and is disposed at a position where an optical path from the light emitting unit to the light receiving unit is blocked by the document placed on the placement unit. Such a sensor can detect that a document is placed as the timing at which the light receiving unit changes from the “light receiving state” to the “non-light receiving state”.

The monitoring unit reads an image of a document placed every time the document sensor detects the placement of the document, and detects a new placement when an image read when a new placement is detected. It is preferable to transmit the above-described message when the images read at the time of detecting the original document placement do not match.
Even if the placed document is once removed, if the same document is placed again, there is no need to send a message to the terminal. By comparing the images read from the placed document and transmitting a message only when the images do not match, the message can be transmitted only when it is certain that the document has been replaced.

  An image reading apparatus according to the present invention includes an operation unit that is operated by a user when document placement is completed, and the receiving unit receives a start command after the operation unit receives a user operation instead of the monitoring unit described above. A monitoring unit may be provided that transmits a message notifying the detection of the new placement to the terminal when a new placement of the document is detected during the period.

  When a user places a document on the placement unit, it is necessary to place the document in a uniform manner, and thus the document may be placed several times. By providing the above-described operation unit and monitoring unit, it is possible to detect only the “new placement” that the user does not expect, without detecting the intentional repositioning of the original by the user as “new placement”. Can be notified to the terminal.

  When the operation unit accepts a user operation, it reads an image of the document, and when a new placement is detected, the image is read again. The image read when the user operation is accepted does not match the image read again. In this case, it is also preferable to transmit the aforementioned message. When the document once removed is placed again, “new placement” is not notified to the terminal.

  When the original is read each time a new placement of the original is detected, it is preferable that the read image includes the read image in the message indicating “new placement”. The user can check the contents of the newly placed document on the terminal screen.

The present invention can be configured as an image reading system in which the above-described image reading apparatus and terminal are connected via a network. In this case, the terminal includes a control unit that displays a message recommending transmission of a start command designating a preset resolution when the above-described message is received from the image reading apparatus.
The preset resolution is preferably the lowest resolution that can be set by the image reading apparatus. The process of reading an image at the lowest resolution can be executed at a higher speed than in the case of a high resolution. The process of reading an image with the lowest resolution corresponds to a process called so-called prescan for confirming the content of the original to be read. That is, when the terminal of this system receives the message “detection of new placement”, it displays a message recommending the user to perform pre-scanning. The user can quickly confirm the contents of the newly placed document by causing the image reading apparatus to perform prescan according to the message.

  According to the present invention, it is possible to provide an image reading apparatus that is connected to a network and operates in a pull scan method, and that can detect replacement of a document after a user places the document. .

The characteristics of the scanner (image reading apparatus) of the embodiment are listed below.
The scanner includes an input unit for inputting an identifier for identifying a transmission destination terminal of the read image. When the transmission source terminal of the start command matches the terminal identified by the input identifier, the monitoring unit transmits a message notifying the detection of new placement to the terminal identified by the identifier.
The user can designate an image transmission destination terminal in advance before placing a document. The above scanner can accept only the start command from the image transmission destination terminal designated in advance by the user even when the start command is accepted from a plurality of terminals. That is, even when a plurality of terminals are connected to the network, a message notifying the detection of new placement can be transmitted to the image transmission destination terminal designated in advance by the user.

(First embodiment)
Embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a block diagram of a scanner 10a (image reading apparatus) of this embodiment. The scanner 10a is connected to the network 92. FIG. 1 also shows another scanner 10b connected to the network 92 and three terminals 90a, 90b, 90c. Since the scanner 10b has the same function as the scanner 10a, description thereof is omitted. There is no limit to the number of scanners or terminals connected to the network.

The configuration of the scanner 10a will be described.
The scanner 10 a includes a communication unit 11, a CPU 12, a placement unit 14, a document sensor 16, a sheet feeding mechanism 18, a console 20, an image reading unit 22, and a storage device 24.
The image reading unit 22 is a unit for reading an image from a document sent from the placing unit 14.
The communication unit 11 is a unit that exchanges data with the terminal 90a and the like. The exchanged data includes a command for controlling the scanner 10a, a message for notifying the terminal 90a of the status of the scanner 10a, and an image read by the scanner 10a.
The placement unit 14 is a unit for placing a document. A document sensor 16 is attached to the placement unit 14. The document sensor 16 is a sensor including a light emitting unit and a light receiving unit. The light emitting unit and the light receiving unit are arranged so that the light emitted from the light emitting unit is emitted to the light receiving unit when no document is placed on the placement unit 14. When a document is placed on the placement unit 14, the light from the light emitting unit to the light receiving unit is blocked by the document. The document sensor 16 detects a change from a state in which the light receiving unit receives light to a state in which no light is received. The fact that the document is placed on the placement unit 14 is detected as a change from the light receiving state to the non-light receiving state.
The sheet feeding mechanism 18 is a mechanism that conveys sheets (originals) placed on the placement unit 14 to the reading unit 22 one by one. The sheet feeding mechanism 18 also conveys the sheet from the reading unit 22 to a sheet discharge unit (not shown). The sheet feeding mechanism 18 can return the sheet to the placing unit 14 instead of conveying the sheet from the reading unit 22 to the sheet discharging unit. A specific mechanism for returning the sheet from the reading unit 22 to the placement unit 14 is, for example, by reversing the sheet feeding mechanism when the end of the sheet is detected at a predetermined position of the sheet feeding mechanism 18. Since it can be realized by discharging, detailed description thereof is omitted.
The console 20 is an operation panel for a user to operate. The user presses a predetermined button (not shown) on the console 20 after placing the document on the placement unit 14. The predetermined button here is a button for causing the scanner 10a to recognize completion of document placement. In other words, when a predetermined button is pressed, the scanner 10a recognizes the completion of document placement by the user. The console 20 is not used in this embodiment. The console 20 is used in a second embodiment described later.

The storage device 24 stores various programs to be executed by the CPU 12. In FIG. 1, “PGM” is an abbreviation for “program”.
The communication program 30 is a program in which processing for communicating with the terminal 90a and the like via the network 92 is described. The communication unit 11 is controlled by the processing of the CPU 12 based on the communication program 30.
The monitoring program 32 is a program describing a process (monitoring process) for monitoring whether or not a document placed on the placing unit 14 has been replaced. The monitoring process will be described later. The output of the document sensor 16 (detection of document placement) is used in the processing of the monitoring program 32.
The reading control program 34 is a program that describes processing for controlling the reading unit 22. The reading control program 34 may specify a resolution for reading a document.

  A control program 91 is stored in the terminal 90a. The control program 91 describes processing for exchanging data with the scanner 10a and processing for displaying a message received from the scanner 10a.

An outline of the operation of the scanner 10a will be described. First, an outline of processing for transmitting an image read from a document to a terminal will be described. A monitoring process (a process for detecting and notifying that a document has been replaced), which is a feature of the present invention, will be described later.
The scanner 10a can read an image from a document placed by the user and transmit the read image to a terminal designated by the user.
The user operates one of the terminals (for example, the terminal 90a) in advance and transmits a reservation command from the terminal to the scanner 10a. The reservation command is a command for causing the scanner 10a to register the terminal that transmitted the command as the image transmission destination terminal. The IP address of the terminal is added to the reservation command. The scanner 10a identifies the terminal that has transmitted the reservation command based on the IP address added to the reservation command. In other words, the IP address added to the reservation command is an identifier for identifying the image transmission destination terminal. In other words, the communication unit 11 when receiving a reservation command with an IP address can be said to be an input unit to which an identifier for identifying a transmission destination terminal of a read image is input.
Since the scanner (scanners 10a and 10b) that can be used via the network is displayed on the screen of the terminal 90a, the user selects a desired scanner (scanner 10a in this embodiment) and selects a reservation command. Send.

  The user places a document on the placement unit 14 of the scanner 10a after transmitting a reservation command from a terminal (for example, the terminal 90a). Next, the user returns to the terminal 90a and transmits an image reading start command from the terminal 90a to the scanner 10a. The scanner 10a that has received the read start command reads the document placed on the placement unit 14 and reads it on the terminal 90a that is the source of the start command (the terminal identified by the identifier attached to the reservation command). Send an image.

Next, an overview of the monitoring process will be described. When the scanner 10a receives a reservation command from the terminal, the scanner 10a starts a monitoring process. In the monitoring process, the output of the document sensor 16 is monitored. That is, it is monitored whether or not a document is placed on the placement unit 14. Each time the placement of a document on the placement unit 14 is detected, the first sheet of the placed document is conveyed to the reading unit 22 and read at a preset low resolution. The sheet sent to the reading unit 22 is returned again to the placing unit 14 by the sheet feeding mechanism 18. By returning the once read sheet to the placing unit 14 again, when a start command is received later, the original can be read again at a resolution specified by the user.
In the monitoring process, each time the document sensor 16 detects the placement of the document, the read image is compared with the image read first after receiving the reservation command. If the comparison result does not match, the last read image is stored. Thereafter, when the start command is received, the stored image is transmitted to the transmission terminal of the start command. The terminal displays the image sent from the scanner 10a on the screen. The user of the terminal (the user who placed the document on the placement unit 14) can be notified that the document placed on the placement unit 14 has been replaced.

  Details of the monitoring process will be described with reference to FIGS. The monitoring process is divided into an initial process and a monitoring main process. FIG. 2 shows a flowchart of the initial process, and FIG. 3 shows a flowchart of the monitoring main process. The initial process and the monitoring main process are described in the monitoring program 32.

The initial process is started when a reservation command is received from the terminal. In the initial process, first, the IP address (identifier identifying the terminal that transmitted the reservation command) attached to the reservation command is stored (step S102). In other words, the terminal identified by the IP address stored in step S102 is registered as the transmission destination terminal of the read image.
Next, the scanner 10a stands by until a document is placed on the placement unit 14 (step S104: NO). The placement of the document on the placement unit 14 is detected by the document sensor 16 described above. Since the initial process is executed in time division and in parallel with other processes, the other processes can be executed during the loop when the determination in step S104 is “NO”. In other words, the CPU 12 is a so-called multitask type. For example, a monitoring process canceling process or the like may be executed during a loop when the determination in step S104 is “NO”. The monitoring main process to be described later is similarly executed in a multitasking manner.

When the placement of the document on the placement unit 14 is detected (step S104: YES), the first sheet of the placed document is read (step S106). The read image is stored. In step S106, as described above, the first sheet of the document is conveyed to the reading unit 22 by the sheet feeding mechanism 18, and when the reading is completed, the sheet is returned to the placing unit 14 again.
When the first sheet is read, the monitoring main process is started and the initial process ends (step S108).

Next, the monitoring main process will be described with reference to FIG.
In the monitoring main process, the processes of steps S202 to S210 are executed according to circumstances until a command for starting image reading (hereinafter referred to as a start command) is received from the terminal that has transmitted the reservation command (step S202). S200: NO). The scanner 10a can identify the terminal that has transmitted the reservation command based on the IP address stored in step S102 described above. The start command is also assigned the IP address of the terminal that transmitted the start command. The scanner 10a checks whether the reservation command transmission source terminal and the start command transmission source terminal are the same by checking the IP address attached to the reservation command with the IP address attached to the start command. to decide. If the reservation command transmission source terminal is not the same as the start command transmission source terminal, a message to the effect that the reservation command has already been received from another terminal and the start command cannot be accepted to the start command transmission source terminal Send.
As described above, since the CPU 12 of the scanner 10a is a multi-task type, other commands such as, for example, even when waiting for a start command reception (even if the determination in step S200 is NO) are performed at any time. A command such as canceling the monitoring main process can be received and executed.

  The scanner 10a detects a new placement of the document on the placement unit 14 until the start command is received (step S200: NO) (step S202). As described above, when a document is placed on the placement unit 14, the irradiated light from the light emitting unit of the document sensor 16 is blocked by the placed document, and the light receiving unit enters a “non-light receiving state”. Therefore, if the document is not replaced after the placement of the document is detected in step S104 in FIG. 2, the light receiving unit remains in the “non-light receiving state”. On the contrary, when the document is replaced, the light receiving unit once enters the “light receiving state” and then enters the “non-light receiving state” again. The monitoring program 32 detects that the light receiving unit of the document sensor 16 changes from the “light receiving state” to the “non-light receiving state”, and recognizes that a document is newly placed on the placement unit 14.

When a new placement of the document is detected in step S202 (step S202: YES), the first sheet of the placed document is read (204) in the same manner as in step S106. Then, the image read in step S106 is compared with the image read in step S204 (step S206). Here, the comparison is to calculate the difference between the image read in step S106 and the image read in step S204. If the difference is smaller than the threshold, it is determined that the two match. If the difference is larger than the threshold, it is determined that the two do not match. If the two do not match (step S208: NO), it is determined that the document has been replaced when the placement of a new document is detected in step S202. In this case, the last read image (the image read in step S204) is stored (step S210). In step S210, the fact that an image mismatch has been detected (that is, the determination in step S208 is NO) is also stored.
When the process of step S210 is completed, a start command is again waited (step S200).
If the image read in step S106 matches the image read in step S204 (step S208: YES), it is determined that the image has not been replaced. In this case, step S210 is skipped and the process proceeds to step S200 again.

When a start command is received from the terminal that has transmitted the reservation command (step S200: YES), the process of step S212 is executed. In step S212, when an image mismatch is detected in the process of step S208 (step S212: YES), the image stored in step S210 is transmitted to the start command transmission source terminal (step S216).
On the other hand, if no image mismatch is detected in the process of step S208 (step S212: NO), all the originals placed on the placement unit 14 are sequentially read and the start command transmission source terminal (that is, the reservation) The read image is transmitted to the command transmission source terminal (step S214).

  In the terminal that has received the image transmitted in the process of step S216 (start command transmission source terminal), the received image is displayed on the screen. The image transmitted in step S216 serves as a message notifying the terminal user of the detection of the new placement of the document on the placement unit 14. The image transmitted in step S216 can inform the user that the document placed by the user (the document when placement was detected in step S104) was unintentionally replaced.

The scanner 10a according to the present embodiment indicates that the user has unintentionally replaced the document between when the document is placed on the placement unit 14 and when the user transmits an image reading start command from the terminal. Can be notified. The scanner 10a does not need to attach a wireless tag to the document. The document sensor 16 can be composed of a low-cost light emitting element and light receiving element. Therefore, hardware for executing the monitoring process can be realized at low cost.
Further, the scanner 10a does not transmit the above-described message until a start command is received. Until the scanner 10a receives the start command (that is, until the terminal transmits the start command), the user may not be in front of the terminal. Conversely, when the start command is received, it is certain that the user is operating the transmission terminal of the start command. By transmitting the above message at the timing when the start command is received, the user can be surely notified of the message. This point is suitable for a scanner connected to a terminal via a network and operated from the terminal. This is because the location of the scanner and the terminal is often far from each other. In such a case, the user places a document on the scanner and operates the terminal to transmit a start command. This is because there is a period that is not in front of the terminal.

A modification of the first embodiment will be described.
In the above description, the configuration in which the initial process shown in FIG. 2 is started on condition that the reservation command is received is described. However, a configuration that does not employ a reservation command may be used. In this case, S102 is not executed. That is, this initial process is started with the power of the scanner 10a turned on. Then, on condition that the document is placed (S104: YES), the process proceeds to S106.
Although a reservation command can be accepted, it is also possible to adopt a configuration in which a document can be read / transmitted without receiving a reservation command. In this case, when a reservation command is received, S102 is executed, but when document placement is detected without receiving a reservation command, the process is started from S104.
Furthermore, in the above description, the configuration in which the process of S214 or S216 is performed in S212 on condition that image mismatch is detected (S212: NO) is described. However, a configuration that does not require the presence or absence of image mismatch detection may be used. In this case, the sheet feeding mechanism 18, S106, and S204 to S208 for returning the sheet conveyed to the reading unit 22 to the placing unit 14 are unnecessary, and S210 detects the placement of the document in S104. In step S202, it is stored again that the placement of the document is detected, and step S212 is configured on the condition that the storage in step S210 is performed. More specifically, after detecting the placement of the document in S104 (S104: YES), if the placement of the document is detected again in S202 (S202: YES), that fact is stored in S210. . Then, in S200, on the condition that the start command has been received (S200: YES), in S212, it is determined whether or not another document placement is stored in S210. If the result of the determination is negative, in other words, in S202, if the placement of the original again is not detected (S212: NO), the original reading / transmission process is executed (S214). On the other hand, if the result is affirmative (S212: YES), a message indicating that there is a possibility that the document has been replaced is transmitted to the terminal to which the start command is transmitted. The transmitted message is displayed (output) on a screen (output device) included in the terminal at the terminal that has received the message. As a result, it is possible to notify the user of the terminal that there is a possibility that the document placed by the user has been replaced.
In addition, it can also be set as the structure which employ | adopted these two modifications with respect to the said description together.

(Second embodiment)
A scanner (image reading apparatus) of the second embodiment will be described. This scanner effectively uses the console 20 described in FIG. 1 in the scanner 10a of the first embodiment. The configuration of the scanner of the present embodiment is the same as that of the scanner 10a described with reference to FIG.
The scanner of this embodiment is different from the scanner 10a of the first embodiment only in the process of step S104 of the initial process described in FIG. The scanner according to the present embodiment determines whether or not the user has operated a predetermined button (a button for causing the apparatus to recognize the completion of document placement) on the console 20 instead of the process of step S104. When receiving the user operation, the scanner according to the present exemplary embodiment executes the process of step S106. The subsequent processing is the same as the processing of the scanner of the first embodiment.
Also in this embodiment, the modifications described in the first embodiment can be adopted as appropriate.

  The scanner according to the present embodiment can definitely determine the completion of document placement by the user by a user operation. If the user cannot place the document properly, the user may place the document on the placement unit 14 several times. In the scanner of this embodiment, even if the user places the document again and again, it is not necessary to judge that the user places the document again as an unintended replacement of the document.

(Third embodiment)
Next, a third embodiment of the present invention will be described. The present embodiment is an image reading system including a scanner and a terminal connected via a network. This system includes the scanner 10a and terminals 90a to 90c shown in FIG. However, the sheet feeding mechanism 18 for returning the sheet conveyed to the reading unit 22 to the placing unit 14 may not be provided.
The scanner 10a of the present embodiment executes the initial process (except for step S106) shown in FIG. That is, when the scanner 10a first detects the placement of a document after receiving a reservation command from the terminal (step S104: YES), the scanner 10a executes a monitoring main process (step S108).
FIG. 4 shows a flowchart of the monitoring main process executed by the scanner 10a of this embodiment. In the monitoring main process, detection of document placement is continued until a start command is received from the reservation command transmission source terminal (step S302).
If the scanner 10a detects a new placement of the document before receiving the start command (step S302: YES), it stores that a “new placement” has been detected (step S304). Then, it again waits for a start command (step S300).

When the start command is received (step S300: YES), the process is executed in step S306. In step S306, if a new placement detection is stored in the process of step S304 (step S306: YES), a message notifying the detection of the new placement is transmitted to the transmission terminal of the start command ( Step S310).
On the other hand, if the detection of new placement is not stored in the process of step S304 (step S306: NO), all the originals placed on the placement unit 14 are sequentially read and the start command transmission source terminal ( The read image is transmitted to the reservation command transmission source terminal (step S308).

FIG. 5 shows the processing of the terminal 90a that has received the message from the scanner 10a.
Upon receiving the “new placement” notification (step S400: YES), the terminal 90a transmits a message indicating that there is a “new placement” and a document reading start command specifying the lowest resolution. A message indicating that it is recommended to be displayed is displayed on the screen (step S402). Thereafter, it waits for a command input from the user (step S404). 5 is described in the control program 91 stored in the terminal 90a.
The user can transmit a start command specifying a low resolution according to a message displayed on the screen. Alternatively, the user may transmit a command for canceling the reservation command. The scanner 10a that has received the command for canceling the reservation command interrupts the monitoring main process.

The scanner 10a of the present embodiment does not need to read the first document every time document placement is detected. Further, the sheet feeding mechanism 18 for returning the sheet conveyed to the reading unit 22 to the placing unit 14 may not be provided. A monitoring process for detecting the document replacement and notifying the user can be realized at low cost.
In this embodiment, the reservation command described in the first embodiment may not be adopted.

Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.
For example, the image reading apparatus may be a composite apparatus having both a printer function and a copy function.
Alternatively, an identifier for identifying an image transmission destination terminal to the scanner may be directly input from the console 20 without using a network. In this case, the console 20 serves as an input unit for inputting an identifier for identifying the image transmission destination terminal.

  Further, the scanner may omit reception of the reservation command. When the placement of the document is detected in a state where the monitoring process is not executed, the above-described monitoring main process may be executed.

  The technical elements described in this specification or the drawings exhibit technical usefulness alone or in various combinations, and are not limited to the combinations described in the claims at the time of filing. In addition, the technology illustrated in the present specification or the drawings achieves a plurality of objects at the same time, and has technical utility by achieving one of the objects.
