Specifically, the ADF 1 includes a document placement section 11, a plurality of conveyance rollers 12, a document guide 13, and a paper discharge section 14, as shown in FIG. Further, the ADF 1 is supported so as to be openable and closable with respect to a document table 21, which will be described later, and also serves as a document cover for a document placed on a contact glass 211 of the document table 21. Here, the ADF 1 is an example of the document transport section in the present invention.

A document is placed on the document placement section 11 . Each of the conveyance rollers 12 is driven by a motor (not shown) to convey the document placed on the document placement section 11 in the conveyance direction D1 (see FIG. 1). The document conveyed by each of the conveyance rollers 12 is conveyed to the paper discharge section 14 through a conveyance path formed inside the ADF 1. The document guide 13 guides the document transported by each of the transport rollers 12 onto the contact glass 211 of the document table 21 . The document whose image data has been read by the image reading section 2 is discharged to the paper discharge section 14 .

The image reading unit 2 reads image data from each document transported by the ADF 1. The image reading unit 2 also reads image data from a document placed on the contact glass 211. Specifically, the image reading section 2 includes a document table 21, a reading unit 22, a mirror 23, a mirror 24, an optical lens 25, and a CCD 26, as shown in FIG.

The document table 21 is formed at the top of the casing of the image processing device 10 . The document table 21 includes a contact glass 211, as shown in FIG. A document is placed on the contact glass 211 .

The reading unit 22 is provided below the contact glass 211, as shown in FIG. The reading unit 22 is configured to be movable in the sub-scanning direction (horizontal direction in FIG. 1) by a moving mechanism (not shown) having a drive unit such as a stepping motor. The reading unit 22 includes a light source 221 and a mirror 222, as shown in FIG. The light source 221 is a plurality of white LEDs arranged along the main scanning direction (the depth direction of the page in FIG. 1). The light source 221 emits one line of white light in the main scanning direction toward the contact glass 211 . The light emitted from the light source 221 passes through the contact glass 211 and is irradiated onto the original placed on the contact glass 211 or onto the original transported by the ADF 1. The mirror 222 reflects the light emitted from the light source 221 and reflected by the original onto the mirror 23 .

In the image reading section 2, when image data is read from a document placed on the contact glass 211, the reading unit 22 is moved in the sub-scanning direction by the moving mechanism. As a result, the light emitted from the light source 221 and irradiated onto the document is scanned in the sub-scanning direction. Further, in the image reading section 2, when image data is read from a document transported by the ADF 1, the reading unit 22 is moved by the moving mechanism to a position facing the document guide 13 of the ADF 1. As a result, the light emitted from the light source 221 and transmitted through the contact glass 211 is irradiated onto the document conveyed by the ADF 1.

The mirror 23 reflects the light reflected by the mirror 222 of the reading unit 22 onto the mirror 24 . Mirror 24 reflects the light reflected by mirror 23 to optical lens 25. The optical lens 25 collects the light reflected by the mirror 24 and makes it enter the CCD 26 .

The CCD 26 is an image sensor having a plurality of photoelectric conversion elements arranged along the main scanning direction. The CCD 26 outputs an electrical signal according to the amount of light it receives. In the image reading unit 2 , light emitted from a light source 221 and reflected by a document is incident on the CCD 26 via a mirror 222 , a mirror 23 , a mirror 24 , and an optical lens 25 . As a result, the CCD 26 outputs an analog electrical signal corresponding to one line of the image of the document. The analog electrical signal output from the CCD 26 is converted into a digital electrical signal (image data) by an analog front end circuit (not shown) and is input to the control unit 5.

The image forming section 3 forms an image on a sheet using an electrophotographic method based on the image data. For example, the image forming section 3 forms an image on a sheet based on the image data read by the image reading section 2 or the image data stored in the storage section 7. Specifically, the image forming section 3 includes a photosensitive drum, a charging device, an optical scanning device, a developing device, a transfer device, a cleaning device, a fixing device, and a paper discharge tray. Note that the image forming section 3 may form an image using another image forming method such as an inkjet method.

The control unit 5 includes control devices such as a CPU 5A, a ROM 5B, and a RAM 5C. The CPU 5A is a processor that executes various calculation processes. The ROM 5B is a nonvolatile storage device in which information such as control programs for causing the CPU 5A to execute various processes is stored in advance. The RAM 5C is a volatile storage device used as a temporary storage memory (work area) for various processes executed by the CPU 5A. In the control unit 5, various control programs stored in advance in the ROM 5B are executed by the CPU 5A. Thereby, the image processing device 10 is controlled in an integrated manner by the control unit 5. Note that the control unit 5 may be configured with an electronic circuit such as an integrated circuit (ASIC), and may be a control unit provided separately from a main control unit that controls the image processing device 10 in an integrated manner. It's okay.

The operation display unit 6 includes a display unit such as a liquid crystal display that displays various information according to control instructions from the control unit 5, and operation keys or a touch panel that inputs various information to the control unit 5 according to user operations. It has an operation section such as.

The storage unit 7 is a nonvolatile storage device. For example, the storage unit 7 is a storage device such as a nonvolatile memory such as a flash memory and an EEPROM (registered trademark), an SSD (solid state drive), or an HDD (hard disk drive).

The storage unit 7 stores authentication information corresponding to each user of the image processing device 10. The authentication information is used to authenticate the user of the image processing device 10. For example, the authentication information is a user name and password.

Furthermore, the storage unit 7 includes a first storage area 71 and a second storage area 72, as shown in FIG. The first storage area 71 is a storage area allocated to each user of the image processing apparatus 10 and dedicated to that user. The storage unit 7 is provided with a first storage area 71 corresponding to the number of users who can log in to the image processing device 10 . The size of the first storage area 71 may be common to all users, or may be different for each individual user. The second storage area 72 is a storage area shared by users of the image processing device 10.

[Configuration of control unit 5]
Next, the configuration of the control section 5 will be explained with reference to FIG. 2.

As shown in FIG. 2, the control unit 5 includes an authentication processing unit 51, a reading processing unit 52, a storage processing unit 53, an acquisition processing unit 54, a processing execution unit 55, a determination processing unit 56, and a first setting processing unit 57. including.

Specifically, the ROM 5B of the control unit 5 stores in advance a document reading program for causing the CPU 5A to execute a document reading process (see FIG. 3), which will be described later. The control unit 5 uses the CPU 5A to execute the document reading program stored in the ROM 5B. Thereby, the control unit 5 functions as an authentication processing unit 51 , a reading processing unit 52 , a storage processing unit 53 , an acquisition processing unit 54 , a processing execution unit 55 , a determination processing unit 56 , and a first setting processing unit 57 . Here, an apparatus including the control section 5, the operation display section 6, and the storage section 7 is an example of the information processing apparatus in the present invention. Note that the document reading program is recorded on a computer-readable recording medium such as a CD, DVD, or flash memory, and is read from the recording medium and installed in a nonvolatile storage device such as the storage unit 7. Good too.

The authentication processing unit 51 uses the authentication information stored in the storage unit 7 to authenticate the user of the image processing apparatus 10 .

For example, the authentication processing unit 51 causes the operation display unit 6 to display an authentication screen used for a predetermined authentication operation in response to a predetermined user operation on the operation display unit 6. Then, the authentication processing unit 51 receives the authentication operation on the authentication screen. For example, the authentication operation is an operation of inputting a user name and password. Thereafter, the authentication processing unit 51 authenticates the user when the information input from the operation display unit 6 matches any of the authentication information stored in the storage unit 7. That is, the user is logged into the image processing apparatus 10. Note that the authentication processing unit 51 detects the currently logged-in user when a predetermined logout operation is performed on the operation display unit 6, when a preset time has elapsed, or when allowing another user to log in. Execute logout processing to log out.

The reading processing unit 52 executes a reading process of reading image data of each document conveyed by the ADF 1. Specifically, the reading processing unit 52 uses the image reading unit 2 to execute the reading process.

The storage processing unit 53 performs a storage process of sequentially storing a plurality of data to be stored in a first storage area 71 (an example of a predetermined storage unit of the present invention) corresponding to a user who is logged in to the image processing device 10. Execute.

Specifically, the storage target includes a plurality of image data read by the reading process. That is, when the reading processing section 52 executes the reading processing, the storage processing section 53 executes the storage processing in which the storage target is a plurality of image data read in the reading processing.

Note that the storage target may include a plurality of image data received from an external facsimile device through facsimile communication performed between the facsimile device and the facsimile device. In this case, the storage unit of the present invention may be the RAM 5C or the second storage area 72. Further, the storage target may include a plurality of image data acquired from an external information processing device or an external storage device. Further, the storage target may include data of a different type from image data, such as document data and music data.

The acquisition processing unit 54 acquires the free space in the first storage area 71 corresponding to the user who is currently logged in to the image processing device 10 .

By the way, during execution of the storage process, it is possible to execute a predetermined process such as acquiring the free space at predetermined intervals and displaying a warning when the obtained free space becomes less than a predetermined amount. Image forming apparatuses are known as related technology.

However, in the image forming apparatus according to the related technology described above, the free space is always acquired at the same interval during execution of the storage process. Therefore, if the acquisition interval of the free capacity is short, the free capacity is acquired in vain when the free capacity is large, and if the free capacity acquisition interval is long, the free capacity is acquired in vain when the free capacity is small. Detection of insufficient free space is delayed.

In contrast, in the image processing device 10 according to the embodiment of the present invention, as described below, the wasteful acquisition of the free space in the first storage area 71 is suppressed, and the detection of the lack of the free space is It is possible to prevent delays.

The processing execution unit 55 executes a predetermined specific process when the free space acquired by the acquisition processing unit 54 is less than a predetermined reference amount.

For example, the reference amount is zero. For example, in the storage process, when the free space in the first storage area 71 corresponding to the logged-in user becomes zero, the remaining storage target is stored in the second storage area 72. In this case, the remaining occupied area of the storage target in the second storage area 72 is counted as the minus free capacity of the first storage area 71 corresponding to the logged-in user. Note that the reference amount may be arbitrarily determined according to the user's operation on the operation display section 6.

For example, the specifying process is a process of stopping the reading process and the storing process and notifying that the free space is less than the reference value. Note that the specifying process may be a process of notifying that the free space is less than the reference value. That is, the processing execution unit 55 does not have to stop the reading process and the storage process when the free space acquired by the acquisition processing unit 54 is less than the reference amount. In this case, after the reading process and the storing process are completed, a first process of deleting the image data stored in the second storage area 72 by these processes and deleting the existing data in the first storage area 71 is performed. A selection operation for selecting one of the second processes for creating the free space for storing the image data stored in the second storage area 72 may be accepted. Here, if the second process is selected, the image data stored in the second storage area 72 is stored in the free space created by deleting the existing data in the first storage area 71. That's fine.

The determination processing unit 56 determines, based on the free capacity acquired by the acquisition processing unit 54, the timing at which the acquisition processing unit 54 acquires the free capacity during execution of the storage process.

Specifically, when the free space acquired by the acquisition processing unit 54 exceeds a predetermined threshold value that is larger than the reference amount, the determination processing unit 56 determines in advance the next acquisition timing by the acquisition processing unit 54. The determination is made after a predetermined first number of image data are stored in the first storage area 71.

Further, when the free space acquired by the acquisition processing unit 54 is less than or equal to the threshold value, the determination processing unit 56 sets the next acquisition timing by the acquisition processing unit 54 to a second number smaller than the first number. The determination is made after the number of image data is stored in the first storage area 71.

For example, the first number is ten. Further, the second number is 1. Note that the first number and the second number may be arbitrarily determined according to the user's operation on the operation display section 6.

The first setting processing unit 57 sets the threshold value based on the amount of image data stored in the first storage area 71 by the storage process.

For example, if the number of image data stored in the first storage area 71 by the storage process is less than the first number, the first setting processing unit 57 stores the image data in the first storage area 71 by the storage process. A value obtained by multiplying the data amount of any one image data by the first number is set as the threshold value.

Further, if the number of image data stored in the first storage area 71 by the storage process exceeds the first number, the first setting processing unit 57 continuously stores the image data in the first storage area 71 by the storage process. Among the first number of image data stored in the first number of image data, the total data amount of the first number of image data having the largest total data amount is set as the threshold value.

Here, the first setting processing unit 57 does not set the threshold value if the threshold setting function is set to be disabled by the user's operation. In this case, the threshold value may be a value set in advance by the user, or may be a value stored in the ROM 5B in advance.

For example, the first setting processing unit 57 displays, on the operation display unit 6, a switching operation screen used for switching between enabling and disabling the threshold value setting function in response to a predetermined user operation on the operation display unit 6. let Then, the first setting processing unit 57 switches between enabling and disabling the threshold setting function in accordance with the switching operation on the switching operation screen.

Note that the control section 5 does not need to include the first setting processing section 57.

[Original reading process]
Hereinafter, an example of the procedure of the document reading process executed by the control unit 5 in the image processing apparatus 10 will be described with reference to FIG. 3. Here, steps S11, S12, . . . represent the numbers of processing procedures (steps) executed by the control unit 5. Note that the document reading process is executed when an instruction to execute the document reading process is input on the operation display section 6.

<Step S11>
First, in step S11, the control unit 5 determines the first acquisition timing. For example, the control unit 5 determines the first acquisition timing after one piece of image data is stored in the first storage area 71.

<Step S12>
In step S12, the control unit 5 starts executing the reading process. Here, the process of step S12 is executed by the reading processing section 52 of the control section 5.

<Step S13>
In step S13, the control unit 5 starts executing the storage process. Here, the process of step S13 is executed by the storage processing unit 53 of the control unit 5.

<Step S14>
In step S14, the control unit 5 executes the free space monitoring process described below.

In addition, in step S11, the control unit 5 may acquire the free space and determine the first acquisition timing based on the obtained free space. In this case, the threshold value may be a value set in advance by the user or a value stored in the ROM 5B in advance.

[Free space monitoring process]
Next, an example of the procedure of the free space monitoring process executed in step S14 of the document reading process will be described with reference to FIG. 4.

<Step S21>
First, in step S21, the control unit 5 determines whether the storage process started in step S13 has ended.

Here, if the control unit 5 determines that the storage process has ended (Yes in S21), the control unit 5 moves the process to step S30. Moreover, if the storage process has not been completed (No side of S21), the control unit 5 moves the process to step S22.

<Step S22>
In step S22, the control unit 5 determines whether the acquisition timing has arrived. Note that the acquisition timing at which it is determined in step S22 whether or not it has arrived is the acquisition timing set in step S11, step S28, or step S29.

Here, when the control unit 5 determines that the acquisition timing has arrived (Yes side of S22), the control unit 5 moves the process to step S23. Moreover, if the acquisition timing has not arrived (No side of S22), the control unit 5 moves the process to step S21.

<Step S23>
In step S23, the control unit 5 determines whether the threshold setting function is enabled.

Here, if the control unit 5 determines that the threshold value setting function is enabled (Yes in S23), the process proceeds to step S24. Further, if the threshold value setting function is set to be disabled (No side of S23), the control unit 5 moves the process to step S25.

In step S23, the control unit 5 may determine whether the mode for reading the document using the ADF 1 is a mixed mode in which image data is read from each of a plurality of documents of different sizes. In this case, the control unit 5 may move the process to step S24 when determining that the reading mode is not the mixed loading mode, and move the process to step S25 when determining that the reading mode is the mixed loading mode. It will be done.

Further, in step S23, the control unit 5 may branch the process based on a preset type of the document to be read. For example, when the control unit 5 determines that the type of original to be read is a document original or a monochrome original, the control unit 5 moves the process to step S24, and determines that the type of original to be read is a photographic original or a color original. In this case, it is conceivable to move the process to step S25.

Further, the process of step S23 may be omitted.

<Step S24>
In step S24, the control unit 5 automatically sets the threshold value based on the amount of image data stored in the first storage area 71 by the storage process started in step S13. Here, the process of step S24 is executed by the first setting processing section 57 of the control section 5.

Specifically, if the number of image data stored in the first storage area 71 by the storage process is less than the first number, the control unit 5 controls the image data stored in the first storage area 71 by the storage process. A value obtained by multiplying the data amount of any one of the image data by the first number is set as the threshold value.

Furthermore, if the number of image data stored in the first storage area 71 by the storage process exceeds the first number, the control unit 5 controls the storage process so that the image data is continuously stored in the first storage area 71 by the storage process. The total data amount of the first number of image data having the largest total data amount among the first number of image data is set as the threshold value.

<Step S25>
In step S25, the control unit 5 obtains the free space. Here, the process of step S25 is executed by the acquisition processing unit 54 of the control unit 5.

<Step S26>
In step S26, the control unit 5 determines whether the free space acquired in step S25 is less than the reference amount.

Here, if the control unit 5 determines that the free space acquired in step S25 is less than the reference amount (Yes in S26), the process proceeds to step S32. Further, if the free space acquired in step S25 is not less than the reference amount (No side in S26), the control unit 5 shifts the process to step S27.

<Step S27>
In step S27, the control unit 5 determines whether the free space acquired in step S25 exceeds the threshold value. Here, if the process of step S24 is not executed, the control unit 5 uses a value set in advance by the user or a value stored in the ROM 5B in advance as the threshold value.

Here, if the control unit 5 determines that the free space acquired in step S25 exceeds the threshold (Yes in S27), the process proceeds to step S28. Further, if the free space acquired in step S25 is less than or equal to the threshold (No in S27), the control unit 5 moves the process to step S29.

<Step S28>
In step S28, the control unit 5 determines the next acquisition timing after the first number of image data is stored in the first storage area 71.

<Step S29>
In step S29, the control unit 5 determines the next acquisition timing after the second number of image data is stored in the first storage area 71. Here, the processing in step S28 and step S29 is executed by the determination processing section 56 of the control section 5.

In addition, in step S11, the control unit 5 may acquire the free space and determine an acquisition interval of the free space during execution of the storage process based on the obtained free space. In this case, the processes from step S27 to step S29 may be omitted.

<Step S30>
In step S30, the control unit 5 obtains the free space. Here, the process of step S30 is executed by the acquisition processing unit 54 of the control unit 5.

<Step S31>
In step S31, the control unit 5 determines whether the free space acquired in step S30 is less than the reference amount.

Here, if the control unit 5 determines that the free space acquired in step S30 is less than the reference amount (Yes in S31), the process proceeds to step S32. Further, if the free space acquired in step S30 is not less than the reference amount (No side of S31), the control unit 5 ends the free space monitoring process.

<Step S32>
In step S32, the control unit 5 executes the specific processing. Here, the process of step S32 is executed by the process execution unit 55 of the control unit 5.

Specifically, when the reading process and the storing process are being executed, the control unit 5 stops the currently executing reading process and the storing process, and also sends a message indicating that the free space is less than the reference value. Notify. Furthermore, when the reading process and the storing process have been completed, the control unit 5 notifies that the free space is less than the reference value.

Here, the control unit 5 may delete the image data stored in the second storage area 72 due to the storage process that has been stopped or completed. Further, the control unit 5 may delete all of the image data stored in the storage unit 7 due to the storage process that has been stopped or completed. The control unit 5 also performs a first process of deleting image data stored in the second storage area 72 due to the stopped or completed storage process, and a process of deleting existing data in the first storage area 71. A selection operation for selecting one of the second processes for creating the free space for storing the image data stored in the second storage area 72 may be accepted.

In this manner, in the document reading process, the timing for acquiring the next free capacity during execution of the storage process is determined based on the free capacity acquired during execution of the storage process. Specifically, when the free space exceeds the threshold, the next acquisition timing is determined after the first number of image data is stored in the first storage area 71. Further, when the free space is less than or equal to the threshold value, the next acquisition timing is determined after the second number of image data smaller than the first number is stored in the first storage area 71. As a result, when the free space is large, the acquisition timing is determined so that the free space acquisition interval becomes long, and when the free space is small, the free space acquisition interval is determined to be short. The acquisition timing is determined. Therefore, it is possible to suppress wasteful acquisition of the free space in the first storage area 71 and to suppress a delay in detecting the lack of free space.

[Other embodiments]
Note that the control unit 5 may include one or both of the second setting processing unit 58 and the generation processing unit 59 shown in FIG.

Here, the second setting processing unit 58 sets one or both of the first number and the second number based on the free space acquired by the acquisition processing unit 54.

Specifically, when the free capacity acquired by the acquisition processing unit 54 exceeds the threshold value, the second setting processing unit 58 increases the first number as the free capacity increases. Further, when the free space acquired by the acquisition processing unit 54 is less than or equal to the threshold value, the second setting processing unit 58 sets the second number to a smaller value as the free space is smaller. This makes it possible to more precisely define the acquisition timing according to the free space, thereby suppressing wasteful acquisition of the free space in the first storage area 71 and detecting a shortage of the free space. It is possible to further enhance the effect of suppressing the delay.

Furthermore, every time image data is stored in the first storage area 71 by the storage process, the generation processing unit 59 generates preview image data based on the image data, and transfers the generated preview image data to the first storage area 71. A generation process to be stored in the storage area 71 is executed. The preview image data generated in the generation process is used for displaying a preview of the image data read in the original reading process after the original reading process is completed.

Here, the processing execution unit 55 stops the generation process when the free space acquired by the acquisition processing unit 54 is less than the reference amount. That is, the specific processing includes processing for stopping the generation processing.

Further, after the processing execution unit 55 stops the generation process, the storage processing unit 53 stores the image data in the storage area of the preview image data stored by the generation process in the first storage area 71. Thereby, even if the free space in the first storage area 71 becomes less than the reference amount during the execution of the storage process, the storage process can be continued without using the second storage area 72. is possible.
