Although the image reading device 101 and the plurality of information processing devices 210 are shown one by one in FIG. 9 for brevity, a plurality of image reading devices and a plurality of information processing devices may exist in the image reading system.

<Image reader>
FIG. 1 is a block diagram showing an example of the functional configuration of the image reading device. The image reading device 101 is intended to read an image of a sheet material, and is controlled by the control means 1.

The control means 1 controls the image reading device 101, for example, controls each motor (not shown) based on an output signal from a sensor (not shown), and each roller (2b, 2c, 4a, 4b) described later. Control the rotation of. The control means 1 has a CPU, ROM, RAM, etc. (not shown), and the CPU realizes various controls by executing a program stored in the ROM.

The control means 1 feeds the sheet material by the paper feeding means 2, and conveys the sheet material to the image reading means 3 for reading the image of the sheet material. The sheet material for which the image has been read by the image reading means 3 is discharged from the image reading device 101 by the paper discharging means 4.

The control means 1 transmits the image data read by the image reading means 3 to the information processing device 210 connected to the image reading device 101 by the data transfer means 5. Alternatively, the information processing device 210 receives a reading condition, a reading start or reading stop command, or the like. This connection method may be a USB interface or a SCSI interface, or may be connected by a wired LAN or wireless.

The image reading device 101 operates by receiving power supplied from the power supply means 6. FIG. 2 is a block diagram showing an example of the functional configuration of the power supply means.

As shown in FIG. 2, the power supply means 6 includes an external power supply unit 6a, a replaceable internal power supply unit (hereinafter referred to as “battery”) 6b, and a battery mounting unit 6c for mounting the battery 6b. The power supply unit 6a is a portion to which power is supplied from a commercial power source or the like, and the battery 6b is a storage battery arranged inside the image reading device 101 for supplying power when the image reading device 101 is separated from the commercial power source. Indicates a functional secondary battery.

The battery 6b may be a secondary battery that can be charged and used repeatedly, but may be a primary battery. When the battery 6b is a secondary battery, the secondary battery may be charged while the external power supply unit 6a is connected to a commercial power source. Further, the battery 6b is a battery that operates all / a part of the image reading device 101.

Further, the power supply means 6 may be configured to have only the battery 6b without having the external power supply unit 6a. In the case of a configuration without an external power supply unit 6a, it is not possible to charge the battery 6b while it is mounted on the main body of the device. Therefore, when the remaining amount of the battery 6b is low, it is necessary to remove the battery 6b from the battery mounting section 6c and replace it. be.

The control means 1 can store the image read by the image reading means 3 in the storage means 7 which is an image memory. If the capacity of the storage means 7 is large, a plurality of image data can be stored. The storage means 7 may be a volatile memory or a non-volatile memory. The storage means 7 may be a memory storage such as an SD card or a USB memory connected to the image reading device 101 by the user.

The control means 1 has a notification means 8 for transmitting the state of the image reading device 101 to the device operator. The notification means 8 may be a display unit using a liquid crystal panel provided in the image reading device 101, an LED indicating the power supply state of the image reading device 101 may be used, or the image read by the image reading device 101 may be displayed. It may be a communication program that displays a message in a dialog box on the receiving host computer.

The control means 1 includes a battery replacement detecting means 9 for detecting whether or not the battery 6b is mounted on the battery mounting portion 6c, and a battery remaining amount detecting means 10 for detecting the remaining charge of the battery 6b. Have. The control means 1 uses the battery based on the result of the voltage at which the battery changes from the mounted state to the mounted state again via the non-mounted state and the result of the remaining battery level increasing after the battery changes to the mounted state again. It can be determined that it has been exchanged.

The control means 1 has an image processing means 11 for adding image processing to the image data read by the image reading means 3. The image processing means 11 can perform various image processing such as shading correction, rearrangement of image data, binarization or graying processing, edge enhancement processing, data compression processing, file generation processing, and file combination processing on the image data. can.

FIG. 3 is a diagram showing an example of the arrangement of the transport paths of the image reading device 101. From the bundle of sheet materials loaded on the paper feed tray 2a, one paper is fed to the transport path one by one by the paper feed roller 2b and the separation roller 2c. The image of the sheet material that has been fed is read by the front surface image reading means 3a and the back surface image reading means 3b, and is discharged to the paper ejection tray by the paper ejection roller 4a and the paper ejection roller 4b.

The image reading device 101 discharges the sheet material that has been read by the front image reading means 3a and the back image reading means 3b, and at the same time, feeds and reads the next sheet material even if the transfer of the image data is not completed. It may be configured to be capable (hereinafter referred to as "look-ahead scan").

<Functions of image reading system>
The image data read by the front image reading means 3a and the back image reading means 3b can be stored in the storage means 7 which is an image memory. If the storage means 7 has a capacity capable of storing an image of the next sheet material, any number of sheet materials can be pre-read and scanned. Further, the storage means 7 can store scan mode settings such as color or monochrome, scan setting values such as scanning resolution, scanning surface, and paper size, and stores the history of scanning operation in the image reading device 101. You can also do it.

By using the battery remaining amount detecting means 10, the control means 1 can detect what percentage of the maximum value the remaining amount of the battery 6b (hereinafter, referred to as “battery remaining amount”) is.

When the control means 1 determines that the remaining battery level is, for example, 20% or less, the look-ahead scan can be disabled. That is, the next sheet material is fed after waiting for the completion of output of the image data. At this time, the notification means 8 may notify that the look-ahead scan has been disabled.

When the control means 1 determines that the remaining battery level is, for example, 10% or less, the control means 1 conveys the sheet material read by the front image reading means 3a and the back image reading means 3b to the position of the paper ejection means. The original is held at the position of the paper ejection means, and after the output of the image data is completed, the sheet material is ejected to the paper ejection tray. After the sheet material is discharged, the next sheet material loaded on the paper feed tray 2a is not fed, and the notification means 7 is used to notify the user of the low battery.

The method of notifying the user of the low battery is to display a message on the display unit of the image reading device 101, change the color of the LED indicating the power status of the image reading device 101, and blink the LED indicating the power status of the image reading device 101. As shown in FIG. 4, the information processing device 210 receiving the read image of the image reading device 101 is made to display a message in a dialog box.

The control means 1 detects that the user has replaced the battery 6b of the image reading device 101 and turned on the power again, reconnected to the information processing device 210, and reads the image reading device 101 as shown in FIG. The information processing device 210 that is receiving the image is displayed with a dialog box for selecting whether to continue or stop the scan. When the user selects to continue scanning, the control means 1 resets the scan mode settings such as color or monochrome, the scanning resolution, the scanning surface, the paper size, etc., which are the same as the scanning setting values before replacing the battery 6b. Then, the scanning of the sheet material remaining in the paper feed tray 2a is restarted.

When scanning continuation is selected in the dialog box shown in FIG. 5, the information processing apparatus 210 uses the image data file generated by image reading before battery replacement and the image data file generated by image reading after battery replacement. Can be combined with and to generate a single image data file. This is especially effective when scanning in a storage format such as a multi-page TIFF file or PDF file.

Here, an example in which the look-ahead scan is invalidated by setting the judgment that the remaining battery level is 20% or less as a threshold value (second threshold value) is given, but it is not necessarily limited to 20% or less (second threshold value or less). Further, although an example of prompting battery replacement is given with the determination that the remaining battery level is 10% or less as a threshold value (first threshold value), the battery replacement is not necessarily limited to 10% or less (first threshold value or less).

<File combination processing>
When generating a multi-page TIFF file or PDF file, the process of combining the image data file generated by image reading before battery replacement and the image data file generated by image reading after battery replacement ( The process of combining into one file) will be described in detail with reference to FIG. The file combination processing in the information processing apparatus 210 will be described below, but the present invention is not limited to this, and the following processing can also be applied to the image reading apparatus 101.

FIG. 6 is a control flow diagram showing an example of file combination before and after battery replacement in the information processing device 210. The processing of the flowchart shown in FIG. 6 is realized by executing a program stored in the ROM by a CPU (not shown). Further, the image reading device 101 may perform a part of the processing of FIG.

It is assumed that the program operating in the information processing device 210 receives, for example, 30 MByte of image data A before replacing the battery. In S601, the CPU of the information processing device 210 stores the image data A in the working storage area (for example, RAM).

In S602, the image reading device 101 that detects that the remaining battery level is low (for example, 10% or less) receives the low battery level notification.

In S603, the image data A of 30 MByte already received can be displayed in a format that can be displayed from the working storage area to the storage storage area (for example, ROM) that can be operated by the user by application software for displaying images. Convert and save.

In S604, the CPU of the information processing device 210 displays a dialog box prompting the user to replace the battery as shown in FIG.

After replacing the battery, in S605, the CPU of the information processing device 210 receives a scan continuation instruction from the user using the dialog box shown in FIG. Then, the CPU of the information processing device 210 transmits a scan continuation instruction to the image reading device 101.

In S606, the program operating in the information processing apparatus 210 receives the additional 70 MByte image data B, stores it in the working storage area, and receives the scan end instruction in S607.

The program operating in the information processing device 210 duplicates the image data A of 30 MByte stored in the user-operable storage storage area in S608 to the work storage area, and adds it to the work storage area in S609. Combined with the generated 70 MByte image data B, 100 MByte image data C is generated.

In S610, the image data file C of 100 MByte is saved in the storage area that can be operated by the user, and the image data file A of 30 MByte already saved in S611 is deleted.

Although the program that uses the work storage area has been described here, the present invention is not limited to this, and a program that does not use the work storage area may be used. In that case, the same processing is performed using the storage storage area for storage.

<Processing of image reader>
FIG. 7 is a control flow diagram of the image reading device. The processing of the flowchart shown in FIG. 7 is realized by the CPU of the control means 1 executing the program stored in the ROM.

In S701, the control means 1 receives scan settings (for example, scan mode settings such as color or monochrome, scanning resolution, scanning surface, paper size, etc.) which are scanning setting information. The scan setting may be received by the user inputting the scan setting via an operation unit (not shown) provided in the image reading device 101, or may be received by the user via the display unit of the information processing device 201. good.

In S701, the control means 1 stores the received scan setting information in the storage means in S702. The storage means may be a non-volatile memory provided inside the image reading device 101, or may be a memory provided in the information processing device 210 connected to the image reading device 101 and set to scan. Or both may be used.

At S703, the control means 1 receives a scan start instruction. The instruction may be by an icon displayed on the display unit of the information processing device 210 for instructing the start of scanning, or by a scan button on the operation unit provided in the image reading device 101.

In S704, the control means 1 detects the remaining battery level and determines whether or not the battery needs to be replaced. For example, using 10% of the remaining battery level as a determination value, it is determined whether the remaining battery level is sufficient or whether the battery needs to be replaced.

When the remaining battery level is 10% or more and it is determined that the battery replacement is unnecessary, the control means 1 switches between enabling and disabling the look-ahead scan with the remaining battery level of 20% as the determination value in S705. If the remaining battery level is more than 20%, the scan proceeds to S708 with the look-ahead scan enabled in S707. When the remaining battery level becomes 20% or less, the look-ahead scan is disabled in S706 and then the scan proceeds in S708.

In S708, the control means 1 of the image reading device 101 scans the sheet material loaded on the paper feed tray 2a. That is, the image is read.

In S708, the control means 1 of the image reading device 101 scans the sheet material loaded on the paper feed tray 2a, and in S709, whether or not the paper feed tray 2a has a sheet material to be scanned next. The judgment is made by the sheet detecting means (not shown). If there is a sheet material, the battery replacement determination in S704 is repeated, and if there is no sheet material, the process proceeds to S710.

When the sheet material of the paper feed tray 2a runs out, the control means 1 of the image reading device 101 displays a dialog box (FIG. 5) in S710 that allows the user to select whether to continuously scan or stop scanning. It is displayed on the display unit of 210. Alternatively, a message may be displayed on the display unit of the image reading device 101. When the user wants to continue scanning, he / she may add a sheet material to the paper feed tray 2a and select to continue scanning.

In S711, the control means 1 of the image reading device 101 determines whether or not an instruction for continuous scanning has been received. When the scan continuation instruction is received, the process returns to the battery replacement determination of S704 and the scan operation is repeated. When the scan continuation instruction is not received, the control means 1 of the image reading device 101 outputs the image data if there is any image data that has not been output, and ends the process.

When it is determined in S704 that the remaining battery level is 10% or less and replacement is necessary, in S712, the control means 1 of the image reading device 101 determines whether or not there is image data that has not been output.

When the remaining battery level is low, the power supply of the image reading device 101 is lost. If the power of the image reading device 101 is lost during the scanning operation, the information processing device 210 determines that an error has occurred in the image reading device 101, so that normal scanning end processing is not performed and before the power is lost. There is a risk that scanned image data cannot be generated. In particular, when the image reading device 101 is wirelessly connected to the information processing device 210 or an external storage device and the image data is stored externally, the scanned image data will be lost unless the image transfer is completed. , The same sheet material needs to be scanned again.

In S713, the control means 1 of the image reading device 101 outputs the image data in order to prevent the image data from being lost due to the decrease in the remaining battery level. The output of the image data may be a method of transmitting the image data to the information processing device 210 or the external storage device connected to the image reading device 101, or if the image data cannot be transmitted to the information processing device 210 or the external storage device, the image A method of outputting image data to a non-volatile memory provided inside the reading device 101 may also be used. The output destination of the image data is not limited to the output destination described above, and it is sufficient if the image data can be output to a storage area that can be operated by the user. If the output of the image data fails, the notification means 8 notifies the user of the disappearance of the image data.

After the output of the image data is completed, the control means 1 of the image reading device 101 notifies the user of the low battery level in S714. As for the decrease in the remaining battery level, the information processing device 210 may display a message prompting the decrease in the remaining battery level and the battery replacement shown in FIG. 4 in a dialog box, or the message may be displayed on the display unit of the image reading device 101. You may.

In S715, the power of the image reading device 101 is turned off. To turn off the power, the user may be prompted to turn off the power and the user may press the power button of the image reading device 101 to turn off the power, or the power may be turned off according to an instruction from the information processing device 210. May be controlled to automatically turn off the power.

Since it is possible that the scanner will not be reconnected after the power is turned off, the image data output to the information processing device 210 before the power is turned off is used by the program operating in the information processing device 210 for work. You may move or duplicate from the working storage area to the storage storage area used for storage that is accessible to the user.

When the control means 1 of the image reading device 101 detects the replacement of the battery in S716, the control means 1 of the image reading device 101 turns on the power of the image reading device 101 in S717. Further, the power may be turned on by the user pressing the power button.

The information processing device 210 is on standby in a state of waiting for connection in order to reconnect the image reading device 101 after the battery of the image reading device 101 is replaced. In S718, the control means 1 of the image reading device 101 is reconnected to the information processing device 210.

For example, when the image reading device 101 is wirelessly connected to the information processing device 210, after the battery is replaced, the user turns on the power of the image reading device 101 in S717 to automatically connect the image reading device 101 before replacing the battery. It may be reconnected to the information processing device 210 that has been used.

The information processing device 210 stores the scan setting information before the battery replacement, and at the same time, stores the scanner-specific identification information such as the serial number of the scanner, and acquires the serial number at the time of reconnection, thereby before the battery replacement. You may check that the same scanner as is connected. Further, by storing the batch number for identifying the image data and acquiring the batch number from the scanner at the time of reconnection, it may be confirmed that the image data should be combined with the image data before the battery replacement. ..

After connecting the image reading device 101 in S718, the control unit 1 of the image reading device 101 resets the scan setting information in S719. The scan setting information reset here is the same as the information set in S701.

After resetting the scan setting information in S719, in S710, a message for confirming battery replacement as shown in FIG. 5 and a dialog box for allowing the user to select whether to continue scanning or stop scanning are displayed. Proceed to the process of displaying.

Although the method of replacing the battery is shown in S716, a method of connecting to a power supply means such as an AC adapter or USB may be used instead of replacing the battery. When connected to a power supply means such as an AC adapter or USB, the configuration may include a charging means for charging the battery inside the device.
