Abstract

<P>PROBLEM TO BE SOLVED: To provide an image output apparatus, its control method and the program that enable an adjustment working of the apparatus by a management and a normal operation of the apparatus to be accurately divided and operated. <P>SOLUTION: The state of the image output part after supplying a power to the image output apparatus is monitored. On a memory unit, the presence or absence of a flag showing that it starts with the management mode is judged. As the result of the judgement, if the flag is present on the memory unit, the management mode for limiting the input from an operation part and a communication part is performed. During performing the management mode, when an instruction input to shift from the management mode to a non-management mode is present after the image output part getting ready for operating as a result of monitoring, next processing is performed. Namely, the non-management mode for permitting the input from the operation part and the communication part by canceling the limitation of the input is performed with shifting from the management mode. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to an image processing apparatus including an image output unit, a communication unit that performs data communication with an external device on a network, and an operation unit that displays information and inputs instructions. More particularly, the present invention relates to an image output apparatus that operates by adaptively switching between an administrator mode and a non-administrator mode in order to prohibit normal operation during a predetermined period after power-on, a control method thereof, and a program. .

  Conventional copiers, printers, and multifunction copiers that function as both printers and copiers have a relatively short time from when the power is turned on until they are ready for copying and printing. Even when power is input from the local UI, the waiting time is short. This is because conventional copiers, printers, and multi-function copiers have a relatively small number of printed sheets per minute, so the temperature and image adjustment of the printing units in copiers, printers, and multi-function copiers can be done in a short time. This is due to being completed.

Here, various types of control have been proposed as the control for powering on the device. For example, in Patent Document 1, identification information from another electronic device is acquired by information communication via a wireless transmission path, and security setting / release is controlled based on the acquired identification information. In particular, even when the power switch of the electronic device is turned on, control is performed so as to permit the power supply of the device itself only when the identification information is the identification information of the specific electronic device. A configuration is disclosed.

It is assumed that it is necessary. Assuming this case, the administrator must make adjustments before using it by a general user. However, in order to do so, it is necessary to wait for the device to start up. In addition, if data is sent during warm-up for printing, there is a possibility that printing will start at the moment the device is started up.

<Description of Image Processing Unit of Scanner I / F>
A detailed description will be given of a portion (image processing unit) responsible for image processing of the scanner I / F 140.

  FIG. 5 is a block diagram illustrating a detailed configuration of the image processing unit of the scanner I / F according to the first embodiment of the present invention.

  An image signal sent from the reader unit 200 via the connector 142 is corrected by the connection & MTF correction unit 601. This is because, for example, when the CCD 218 is a 3-line CCD, the reading position between the lines is different in the splicing process, so that the delay amount for each line is adjusted according to the reading speed so that the reading positions of the three lines are the same. Correct the signal timing. In MTF correction, since the MTF for reading varies depending on the reading speed, the connection & MTF correction unit 601 corrects the change. The digital signal whose reading position timing is corrected corrects the spectral characteristics of the CCD 218 and the spectral characteristics of the lamp 212 and the mirrors 214 to 216 by the input masking unit 602. The output of the input masking unit 602 is sent to the ACS count unit 405 and the main controller 111.

<Description of ACS Count Unit>
FIG. 6 is a diagram showing a detailed configuration of an ACS (auto color select) count unit according to the first embodiment of the present invention.

  Auto color select (hereinafter, ACS) determines whether a document is color or monochrome. Specifically, the saturation for each pixel is calculated, and color determination is performed based on how many pixels having the calculated saturation equal to or greater than a threshold value. However, even for a black and white original, due to the influence of MTF and the like, when viewed microscopically, there are a large number of color pixels around the edge, and it is difficult to simply perform ACS determination on a pixel basis. Although various methods are provided for this ACS method, in the first embodiment, since it is not particular to the ACS method, a description will be given by a very general method.

  As described above, even in a black and white image, there are many color pixels when viewed microscopically. Therefore, whether or not the pixel is really a color pixel is determined based on information on surrounding color pixels with respect to the target pixel. There is a need. Reference numeral 501 denotes a filter for this purpose, which has a FIFO structure in order to refer to surrounding pixels with respect to the target pixel. The area detection circuit 502 creates an area signal 505 to which ACS is applied based on the values set in the registers 507 to 510 set from the main controller 111 and the video control signal 512 sent from the reader unit 200.

  Based on the region signal 505 to which ACS is applied, the color determination unit 503 refers to the peripheral pixel in the memory in the filter 501 with respect to the target pixel, and determines whether the target pixel is a color pixel or a monochrome pixel. The counter 504 is a counter that counts the number of color determination signals 506 output from the color determination unit 503.

  The main controller 111 determines an area to be subjected to ACS with respect to the reading range, and sets it in the registers 507 to 510 (in the first embodiment, the range is determined independently for the document). Further, the main controller 111 compares the value of the counter that counts the number of color determination signals in the area to which ACS is applied with a predetermined threshold value, and based on the comparison result, whether the document is color or monochrome Judging.

  In the registers 507 to 510, the position where the color determination unit 503 starts the determination and the position where the determination ends are set in each of the main scanning direction and the sub-scanning direction based on the video control signal 512 sent from the reader unit 200. Keep it. In the first embodiment, each size is set to be about 10 mm smaller than the actual document size.

<Description of Image Processing Unit of Printer I / F>
A detailed description will be given of a portion (image processing unit) responsible for image processing of the printer I / F 145.

  FIG. 7 is a block diagram illustrating a detailed configuration of the image processing unit of the printer I / F according to the first embodiment of the present invention.

  An image signal sent from the main controller 111 via the printer bus 146 is first input to the LOG conversion unit 701. The LOG converter 701 converts RGB signals to CMY signals by LOG conversion. Next, moire is removed by the moire removing unit 702. In the UCR & masking unit 703, the CMY signal that has been subjected to moire removal processing is generated by UCR processing, and is corrected to a signal that matches the output of the printer by masking processing. The signal processed by the UCR & masking unit 703 is subjected to density adjustment by the γ correction unit 704 and then smoothed or edge processed by the filter unit 705. Through these processes, an image is sent to the printer unit 300 via the connector 147.

<Description of Graphic Processor>
A detailed description of the graphic processor 135 will be given.

  FIG. 8 is a block diagram showing a detailed configuration of the graphic processor according to the first embodiment of the present invention.

  The graphic processor 135 includes modules that respectively perform processing of an image rotation unit 801, an image scaling unit 802, a color space conversion unit 803 using the LUT 804, and an image binarization unit 805. The SRAM 136 is used as a temporary work area for each module of the graphic processor 135. It is assumed that a work area is statically allocated for each module in advance so that the work area of the SRAM 136 used by each module does not compete. The graphic processor 135 is connected to the main controller 111 via the I / F 137, and data transfer to and from the DRAM 116 is controlled by the bus controller 113 and DMA transfer.

  The bus controller 113 performs control for setting a mode and the like for each module of the graphic processor 135 and timing control for transferring image data to each module.

<Description of image rotation unit>
The processing procedure in the image rotation unit 801 is shown below.

  Settings for image rotation control are performed from the CPU 112 to the bus controller 113 via the I / F 137. With this setting, the bus controller 113 performs settings necessary for image rotation (for example, image size, rotation direction / angle, etc.) for the image rotation unit 801. After performing the necessary settings, the CPU 112 permits the bus controller 113 to transfer image data again. In accordance with this permission, the bus controller 113 starts transferring image data from the DRAM 116 or a device connected via each I / F.

  Here, the size of the image to be rotated is 32 pixels × 32 lines, and when transferring image data on the I / F 137, image transfer is performed in units of 24 bytes (8 pixels for each RGB). And

  As described above, in order to obtain an image of 32 pixels × 32 lines, it is necessary to perform the above unit data transfer 32 × 32 times, and it is necessary to transfer image data from discontinuous addresses (FIG. 9). reference).

  The image data transferred by the discontinuous addressing is written in the SRAM 136 so as to be rotated at a desired angle at the time of reading. For example, if the rotation is 90 degrees counterclockwise, the transferred image data is written in the Y direction as shown in FIG. At the time of reading, the image is rotated by reading in the X direction.

  After the image rotation of 32 pixels × 32 lines (writing to the SRAM 136) is completed, the image rotation unit 801 reads the image data from the SRAM 136 by the above-described reading method, and transfers the image to the bus controller 113.

  The bus controller 113 that has received the rotated image data transfers the data to the DRAM 116 or each device on the I / F by continuous addressing.

  Such a series of processing is repeated until there is no processing request from the CPU 112 (until processing of the required number of pages is completed).

<Description of image scaling unit>
The processing procedure in the image scaling unit 802 is shown below.

  Settings for image scaling control are performed from the CPU 112 to the bus controller 113 via the I / F 137. With this setting, the bus controller 113 performs settings necessary for image scaling (magnification / magnification in the main scanning direction, magnification / magnification in the sub-scanning direction, image size after magnification, etc.) to the image magnification / reduction unit 802. After performing the necessary settings, the CPU 112 again permits image data transfer to the bus controller 113. In accordance with this permission, the bus controller 113 starts transferring image data from the DRAM 116 or a device connected via each I / F.

  The image scaling unit 802 stores the received image data in the temporary SRAM 136. Then, the image scaling unit 802 uses the SRAM 136 as an input buffer to perform interpolation processing for the number of pixels and the number of lines necessary for the stored data according to the scaling factor of main scanning and sub scanning. Scaling processing is realized by enlarging or reducing the image. The scaled data is written back to the SRAM 136 again, and this is used as an output buffer. The image scaling unit 802 reads the image data from the SRAM 136 and transfers it to the bus controller 113.

With this setting, the bus controller 113 performs settings necessary for color space conversion processing (matrix calculation coefficients described later, table values of the LUT 804, etc.) for the color space conversion unit 803 and the LUT (look-up table) 804. After performing the necessary settings, the CPU 112 again permits image data transfer to the bus controller 113. In accordance with this permission, the bus controller 113 starts transferring image data from the DRAM 116 or a device connected via each I / F.

  The color space conversion unit 803 first performs a 3 × 3 matrix operation represented by the following equation for each pixel of the received image data.

  In the above formula, R, G, B are input, X, Y, Z are output, a11, a12, a13, a21, a22, a23, a31, a32, a33, b1, b2, b3, c1, c2, c3 are Each is a coefficient.

  Various color space conversions such as conversion from the RGB color space to the Yuv color space can be performed by the calculation of the above equation.

  Next, conversion by the LUT 804 is performed on the data after the matrix calculation. Thereby, non-linear conversion can also be performed. Of course, it is possible to substantially not perform the LUT conversion by setting a table for passing through the conversion process.

  Thereafter, the color space conversion unit 803 transfers the image data subjected to the color space conversion processing to the bus controller 113.

  The bus controller 113 that has received the color space converted image data transfers the data to the DRAM 116 or each device on the I / F.

<Description of Image Binarization Unit>
The processing procedure in the image binarization unit 805 is shown below.

  Settings for binarization control are performed from the CPU 112 to the bus controller 113 via the I / F 137. With this setting, the bus controller 113 performs settings necessary for the binarization processing (various parameters and the like according to the conversion method) for the image binarization unit 805. After performing the necessary settings, the CPU 112 again permits image data transfer to the bus controller 113. In accordance with this permission, the bus controller 113 starts transferring image data from the DRAM 116 or a device connected via each I / F.

  The image binarization unit 805 performs binarization processing on the received image data. In the first embodiment, as a binarization method, image data is simply binarized by comparing with a predetermined threshold. Of course, any method such as a dither method, an error diffusion method, or an improved error diffusion method may be used.

  Thereafter, the image binarization unit 805 transfers the binarized image data to the bus controller 113.

  The bus controller 113 that has received the binarized image data transfers the data to the DRAM 116 or each device on the I / F.

<Sequence when outputting PDL image>
FIG. 11 is a flowchart showing a procedure for outputting a PDL image according to the first embodiment of the present invention. Note that S3001 to S3008 in the figure indicate each step.

  When outputting a PDL image, in step S3001, the user performs print settings for the PDL image output job on the host computer 401. Thereby, a print setting parameter is generated. The print setting contents include the number of copies, paper size, single side / double side, page output order, sort output, presence / absence of stapling, and the like.

  In step S3002, a print instruction is given on the host computer 401. As a result, the driver software installed on the host computer 401 converts the code data on the host computer 401 to be printed into so-called PDL data. Then, the PDL data is transferred via the network 400 to the control device 110 together with the print setting parameters set in step S3001.

  In step S3003, the CPU 112 of the main controller 111 of the control device 110 receives the PDL data and print setting parameters transferred via the connector 122 and the network controller 121. Then, based on the received print setting parameters, the PDL data is developed (rasterized) into image data. The development of the image data is performed on the DRAM 116. When the development of the image data is completed, the process proceeds to step S3004.

  In step S3004, the main controller 111 transfers the image data developed on the DRAM 116 to the graphic processor 135.

  In step S3005, the graphic processor 135 performs image processing independently of the print setting parameters. For example, in some cases, the paper size specified by the print setting parameter is A4, but the paper feed unit 360 of the printer unit 300 has only A4R size paper. In this case, the image can be output in accordance with the output sheet by rotating the image by 90 degrees with the graphic processor 135. When the image processing of the image data is completed, the process proceeds to step S3006.

  In step S3006, the graphic processor 135 transfers the image data after image processing to the main controller 111. The main controller 111 stores the transferred image data on the DRAM 116.

  In step S3007, the main controller 111 transfers the image data on the DRAM 116 to the printer unit 300 at an appropriate timing while controlling the printer unit 300 via the printer I / F 145 and the connector 147.

  In step S3008, the control device 110 controls the printer unit 300 to print out image data. When the transfer of the image data is completed, that is, when the PDL job is finished, the print output is finished.

<Sequence when outputting copy image>
FIG. 12 is a flowchart showing a copy image output procedure according to the first embodiment of the present invention. Note that S4001 to S4007 in the figure indicate each step.

  When outputting a copy image, in step S4001, the user performs copy settings for the copy image output job on the operation unit 150. Thereby, a copy setting parameter is generated. The copy setting contents include the number of copies, the paper size, single side / double side, enlargement / reduction ratio, sort output, presence / absence of stapling.

  In step S4002, when a copy start instruction is given on the operation unit 150, the main controller 111 of the control device 110 controls the reader unit 200 via the scanner I / F 140 and the connector 142 to perform reading operation of document image data. .

  Specifically, first, the document feeding unit 250 feeds the placed documents one by one onto the platen glass 211, and simultaneously detects the size of the document. Image data is read by exposing and scanning the document based on the detected size of the document. The read image data is stored on the DRAM 116.

  Here, in the conventional copying machine, the magnification in the sub-scanning direction is changed by changing the moving speed of the optical unit 213 according to the setting of the enlargement / reduction ratio of the copy setting, that is, according to the magnification in the sub-scanning direction. Processing was realized. However, in the first embodiment, image data is always read at the same magnification (100%) regardless of the setting of the enlargement / reduction ratio of the copy setting. The scaling process is performed by a graphic processor 135 described later in both the main scanning direction and the sub-scanning direction.

  In step S4003, the main controller 111 transfers the image data on the DRAM 116 to the graphic processor 135.

  In step S4004, the graphic processor 135 performs image processing based on the copy setting parameters. For example, when enlargement of 400% is set, scaling processing in both the main scanning direction and the sub-scanning direction is performed using an image scaling unit that is a module in the graphic processor 135. When the image processing of the image data is completed, the process proceeds to step S4005.

  In step S4005, the graphic processor 135 transfers the image data after image processing to the main controller 111. The main controller 111 stores the transferred image data on the DRAM 116.

  In step S4006, the main controller 111 transfers the image data on the DRAM 116 to the printer unit 300 at an appropriate timing while controlling the printer unit 300 via the printer I / F 145 and the connector 147.

  In step S4007, the control device 110 controls the printer unit 300 to print out image data. When the transfer of the image data is completed, that is, when the copy job is finished, the print output is finished.

  Next, characteristic processing of the first embodiment will be described with reference to FIG.

  FIG. 14 is a flowchart showing a flow of operation management control by key input according to the first embodiment of the present invention.

  In step S1402, the control device 210 is powered on based on a user operation on the main power switch 380. Next, in step S1403, the CPU 112 copies the basic program at the time of startup from the ROM 114 to the DRAM 116 to the BOOTROM memory area 1503 on the DRAM 116, and executes the basic program using the program area 1502. Here, FIG. 15 shows the arrangement of storage areas on the DRAM 116.

  In step S1404, the basic program initializes the I / O control unit 126, the LCD controller 131, the operation unit I / F 132, and the HD drive 160.

  After completion of the initialization operation, in step S1405, the CPU 112 determines whether or not a specific key on the key input unit 1601 of the operation unit 150 is pressed.

  The specific key may be, for example, a dedicated key provided on the key input unit 1601, a predetermined key on the numeric keypad 705, or a combination of key inputs in a predetermined order. good. Alternatively, a predetermined key on the key input unit 1601 that is pressed simultaneously when the main power switch 308 or the operation unit power switch 701 is turned on may be used.

  If the CPU 112 determines that a specific key is pressed via the I / O control unit 126 (YES in step S1405), the CPU 112 sets an administrator mode activation flag in the DRAM 116 in step S1406. Here, the CPU 112 writes a predetermined value indicating the administrator mode activation flag in the activation mode storage area 1504 on the DRAM 116.

  On the other hand, if the CPU 112 determines that the specific key is not pressed via the I / O control unit 126 (NO in step S1405), the process proceeds to step S1407.

  After the process of step S1406, in step S1407, the CPU 112 copies the main program stored in the HD 162 to the main program area 1501 on the DRAM 116 via the HD drive 160. Thereafter, the main program is started.

  In step S1408, the CPU 112 initializes the graphic processor 135 and the network controller 121 via the bus controller 113 while following the main program. In addition, the CPU 112 initializes the serial communication controller 127, the printer I / F 145, and the scanner I / F 140. At this time, the CPU 112 performs serial communication with the reader unit 200 and the printer unit 300 via the bus controller 113 and the serial communication controller 127, and requests initialization of the reader unit 200 and the printer unit 300.

  The printer unit 300 and the reader unit 200 requested to initialize start the initialization process so that the CPU 112 can input and output images.

  Next, in step S 1409, the CPU 112 determines whether or not a predetermined value (administrator mode activation flag) is written in the activation mode storage area 1504 on the DRAM 116. If the CPU 112 determines that a predetermined value is written in the activation mode storage area 1504 (YES in step S1409), the process proceeds to step S1410 to execute the administrator mode. On the other hand, if the CPU 112 determines that the predetermined value is not written in the activation mode storage area 1504 (NO in step S1409), the process proceeds to step S1422 to execute the non-administrator mode.

  In step S1410, CPU 112 executes offline processing of network 400. This process is a process (network communication restriction process) for prohibiting the network controller 121 from receiving data from the host computers 401 and 402 on the network 400 via the bus controller 113.

  In step S1411, an input restriction process is performed to restrict input from the touch panel unit 1602 sent from the operation unit I / F 132 via the I / O control unit 126. At the same time, in step S1412, the operation of the general user (non-administrator) is restricted to the touch panel unit 1602 of the operation unit 150 via the I / O control unit 126, the LCD controller 131, and the operation unit I / F 132. Display a message.

  Thereafter, in step S1413, the CPU 112 monitors the operation state of the printer unit 300 via the serial communication controller 127 that has been initialized. In step S <b> 1414, it is determined whether the printer unit 300 can print based on the monitoring result. If the printer unit 300 is not in a printable state (NO in step S1414), the process returns to step S1413.

  On the other hand, if the printer unit 300 is in a printable state (YES in step S1414), the process advances to step S1415. In step S1415, a message indicating that the administrator can perform adjustment work is displayed on the touch panel unit 1602 of the operation unit 150 via the I / O control unit 126, the LCD controller 131, and the operation unit I / F 132.

  Next, in step S <b> 1417, the CPU 112 monitors key operation (input restriction release operation) of the key input unit 1601 on the operation unit 150. Specifically, the key input for canceling the input restriction set in advance in the program in the main program area 1501 of the DRAM 116 that is input to the operation unit I / F 132 via the I / O control unit 126 is monitored. In other words, the key input for instructing the movement from the administrator mode to the non-administrator mode is monitored.

  This key input also cancels the input restriction by a predetermined key operation, similar to the key input for executing the administrator mode.

  In step S1417, the presence / absence of key input is determined based on the monitoring result. If there is no key input (NO in step S1417), the flow advances to step S1416. On the other hand, if there is a key input (YES in step S1417), that is, if the input restriction can be released, the process proceeds to step S1418.

  In step S1418, the message displayed on the touch panel unit 1602 of the operation unit 150 is deleted, and the input restriction of the operation unit I / F 132 is released so that all operations from the operation unit 150 can be executed. In addition to this, by performing input / output of document images using the printer unit 300 and the reader unit 200, an adjustment operation of the output image by the administrator is accepted.

  The image adjustment operation includes, for example, an operation of calibrating a difference in device characteristics such as a color characteristic when the image input from the reader unit 200 is output to the printer unit 300. When this adjustment work is executed, an adjustment screen is displayed on the touch panel unit 1602 of the operation unit 150 by a predetermined operation.

  Then, the administrator may instruct the CPU 112 to release the network communication restriction from the network 400 via the operation unit 150 after performing the image adjustment work using the reader unit 200 and the printer unit 300. it can.

  Therefore, in step S1419, a cancellation instruction for releasing the network communication restriction is monitored. In step S1420, the presence / absence of a release instruction is determined based on the monitoring result. If there is no cancel instruction (NO in step S1420), the process returns to step S1419. On the other hand, if there is a release instruction (YES in step S1420), the flow advances to step S1421.

  In step S1421, the CPU 112 executes online processing of the network 400 in accordance with a release instruction from the administrator. This process is a process for permitting the network controller 121 to receive data from the host computer 401, the host computer 402, etc. via the network 400 via the bus controller 113. At the same time, in step S1422, the user can perform a general operation (normal operation) on the touch panel unit 1602 of the operation unit 150 via the I / O control unit 126, the LCD controller 131, and the operation unit I / F 132. Message is displayed.

  As described above, according to the first embodiment, after the image input / output system 100 is turned on, the touch panel unit 1602 on the operation unit 150 is operated according to a specific key operation of the key input unit 1601 on the operation unit 150. Limit input from. That is, after the power is turned on, when the system adjustment is necessary, the administrator mode that can be operated only by the administrator can be executed to lock the operation screen and print processing. This prevents general users (non-administrators) from operating the system prior to system adjustment and executing various operations such as unintended copying and printing in the system prior to system adjustment. Is possible.

(Embodiment 2)
In the first embodiment, the configuration in which the administrator mode and the non-administrator mode are adaptively switched according to a specific key operation of the key input unit 1601 on the operation unit 150 has been described. In contrast, the second embodiment describes a configuration in which the administrator mode and the non-administrator mode are adaptively switched when the image input / output system 100 is turned on from an external device such as a host computer via a network. To do.

  Various configurations of the image input / output system 100 of the second embodiment are the same as those of the first embodiment.

  FIG. 16 is a flowchart showing a flow of operation management control when power is turned on via the network according to the second embodiment of the present invention.

  Note that the flowchart shown in FIG. 16 is started in the sleep mode in which the operation from the operation unit 150 is prohibited, although the main power switch 380 of the image input / output system 100 is turned on. Here, as described above, the sleep mode is a state in which the main controller 111 suppresses power consumption by stopping the program in an interrupt waiting state in preparation for network printing, facsimile, or the like.

  In step S1602, the network controller 121 receives data (power-on request) from a host computer (for example, the host computer 401) on the network 400.

  In step S1603, the network controller 121 compares the IP address (identification information) of the host computer that has transmitted the data with the IP address registered in advance in the network controller 121. Then, based on the comparison result, it is determined whether or not the IP address of the host computer is a registered IP address.

  If it is not a registered IP address (NO in step S1603), the process returns to step S1602. On the other hand, if it is a registered IP address (YES in step S1603), the process proceeds to step S1604, and a predetermined value (administrator activation mode flag) is written in the activation mode storage area 1504 on the DRAM. Thereafter, in step S1605, the control device 210 is powered on.

  In step S <b> 1606, the CPU 112 copies the startup basic program from the ROM 114 to the DRAM 116 to the BOOTROM memory area 1503 on the DRAM 116, and executes the basic program using the program area 1502.

  In step S1607, the basic program performs an initialization operation of the I / O control unit 126, the LCD controller 131, the operation unit I / F 132, and the HD drive 160.

  Next, in step S 1608, the CPU 112 copies the main program stored in the HD 162 to the main program area 1501 on the DRAM 116 via the HD drive 160. Thereafter, the main program is started.

  In step S1609, the CPU 112 initializes the graphic processor 135, the serial communication controller 127, the printer I / F 145, and the scanner I / F 140 via the bus controller 113 while following the main program. In addition to this, the CPU 301 reinitializes the Network Controller 121. At this time, the CPU 112 performs serial communication with the reader unit 200 and the printer unit 300 via the bus controller 113 and the serial communication controller 127, and requests initialization of the reader unit 200 and the printer unit 300.

  The printer unit 300 and the reader unit 200 requested to initialize start the initialization process so that the CPU 112 can input and output images.

  Next, in step S1610, the CPU 112 executes offline processing of the network 400. This process is a process (network communication restriction process) for prohibiting the network controller 121 from receiving data from the host computer 401 or the host computer 402 on the network 400 via the bus controller 113.

  In step S <b> 1611, input restriction processing for restricting input from the touch panel unit 1602 sent from the operation unit I / F 132 via the I / O control unit 126 is executed. At the same time, in step S1612, the operation of the general user (non-administrator) is restricted to the touch panel unit 1602 of the operation unit 150 via the I / O control unit 126, the LCD controller 131, and the operation unit I / F 132. Display a message.

  Since subsequent steps S1613 to S1622 correspond to steps S1413 to S1422 of FIG. 14 of the first embodiment, description thereof will be omitted.

  As described above, according to the second embodiment, the same effect as that of the first embodiment can be realized even when the image input / output system 100 is powered on remotely via a network.

(Embodiment 3)
The DRAM 116 may be provided with a nonvolatile area using a nonvolatile memory or a backup power source. In this case, the predetermined value written in the activation mode storage area 1504 of the DRAM 116 can keep the predetermined value regardless of the power OFF / ON.

  Therefore, the user can set a predetermined value (administrator mode activation flag) for starting up in the administrator mode in advance in the activation mode storage area 1504 of the DRAM 116 by an instruction via the operation unit 150. In this case, when power is turned on, it is possible to automatically limit input without performing any special operation or processing. Specifically, it is possible to automatically limit the input of operation input from the touch panel unit 1602 of the operation unit 150 and data input from the network controller 121.

  It should be noted that setting whether or not to keep the predetermined value (administrator mode start flag) in the start mode storage area 1504 of the DRAM 116 between the power OFF / ON is, for example, a predetermined operation when the power is turned off. It is realized by doing. This predetermined operation can be realized by a predetermined key operation on the key input unit 1601 of the operation unit 150, for example.

  It is also possible to set an administrator mode activation flag as an initial value of the activation mode storage area 1504 of the DRAM 116 in the basic program stored in the ROM 114. Also in this case, as described above, it is possible to automatically limit the input of the operation input from the operation unit I / F 132 and the data input from the network controller 121.

  The processing flow at this time has a configuration shown in FIG. 17 in which some steps of the processing flow of FIG. 14 of the first embodiment are omitted. As shown in FIG. 17, in the third embodiment, step S1405 of FIG. 14 of the first embodiment is omitted.

  As described above, according to the third embodiment, in addition to the effect described in the first embodiment, when the configuration in which the administrator mode activation flag is stored in the nonvolatile memory is realized, the next time from power-off. Even when the power is turned on, the administrator mode can be automatically activated.

(Embodiment 4)
In the processing described in the first to third embodiments, when the network communication restriction to the network controller 121 is applied, the network controller 121 returns an error to the external apparatus that has transmitted the data. Thereby, it is possible to notify that the image input / output system 100 cannot be used via the network.

(Embodiment 5)
The CPU 112 automatically applies the processing for restricting the input to the operation input from the touch panel unit 1602 of the operation unit 150 and the data input from the network controller 121 in the following cases. Is also possible. For example, when the CPU 112 monitors the status of the printer unit 300 via the printer I / F 145 or performs an adjustment operation on the printer unit 300, the CPU 112 automatically applies a process for restricting input. It is also possible.

  However, in order to realize this processing, the user can operate the operation unit 150 in a state where the predetermined value written in the activation mode storage area 1504 of the DRAM 116 can continue to be held regardless of the power OFF / ON. Need to give instructions through. That is, the CPU 112 needs to set the operation of the administrator mode activation flag in advance for the activation mode storage area 1504 of the DRAM 116.

  The features of the present invention can be summarized as follows.

  The feature of the present invention constitutes two types of power-on functions for the image input / output system: normal power-on and administrator power-on. When the administrator power is turned on, various operations and processes such as prohibition of operation from the operation unit by the user and input of a printer job are restricted during the warm-up of the image input / output system and after the warm-up is finished (FIG. 18). ).

  For example, the administrator power is turned on as follows.

(1) When a predetermined key is operated on the key input unit 1601 of the operation unit 150 after the power is turned on by the main power switch 308. (2) Via a telephone line by an external device of a mobile phone, a mobile terminal, or a host computer 401 or 402 (3) When the administrator mode activation flag can be stored when the power was turned off last time, the next time the power is turned on After the power is turned on for the administrator, the operation by the administrator Thus, the restriction on job input for the user can be released. That is, when adjustment is necessary after the image input / output system is activated, the administrator power is turned on by a predetermined method, and the operation screen of the touch panel unit 601 on the operation unit 150 is locked and print processing is prohibited. As a result, the user can prohibit the copy operation and the print operation in the system before the system adjustment.
