  Hereinafter, each block in the controller unit 30 shown in FIG. 8 will be described.

  FIG. 9 shows the configuration of the scanner image processing unit 2080. The image bus I / F controller 2081 is connected to the image bus 2008 and controls the bus access sequence and generates control and timing of each device in the scanner image processing unit 2080. The filter processing unit 2082 performs a convolution operation with a spatial filter. For example, the editing unit 2083 recognizes a closed area surrounded by a marker pen from the input image data, and performs image processing such as shading, shading, and negative / positive inversion on the image data in the closed area. A scaling unit 2084 performs enlargement and reduction by performing an interpolation operation in the main scanning direction of the raster image when changing the resolution of the read image.

The image bus I / F controller 2091 is connected to the image bus 2008, and controls the bus access sequence and generates control and timing of each device in the scanner image processing unit 2090. A resolution conversion unit 2092 performs resolution conversion for converting image data coming from the network 2011 or the public line 2051 to the resolution of the printer 20. The smoothing processing unit 2093 performs processing to smooth out jaggies of the image data after resolution conversion (roughness of an image appearing at a black and white border such as an oblique line).

  The configuration of the image compression unit 2040 is shown in FIG.

Control. The processing procedure of the image compression processing unit is shown below.

  Settings for image compression control are performed from the CPU 2001 to the image bus I / F controller 2041 via the image bus 2008. With this setting, the image bus I / F controller 2041 performs settings necessary for image compression (for example, MMR compression and JBIG expansion) for the image compression unit 2043. After performing the necessary settings, the CPU 2001 again permits image data transfer to the image bus I / F controller 2041. In accordance with this permission, the image bus I / F controller 2041 starts transferring image data from each device on the RAM 2002 or the image bus 2008. The received image data is temporarily stored in the input buffer 2042, and the image is transferred at a constant speed in response to an image data request from the image compression unit 2043. At this time, the input buffer determines whether image data can be transferred between the image bus I / F controller 2041 and the image compression unit 2043, reads the image data from the image bus 2008, and reads the image compression unit 2043. When it is impossible to write an image on the screen, control is performed so as not to transfer data (hereinafter, such control is referred to as handshaking).

  The image compression unit 2043 temporarily stores the received image data in the RAM 2044. This is because several lines of data are required depending on the type of image compression processing to be performed, and several lines of image data are prepared in order to compress the first one line. This is because the image cannot be compressed unless it is empty. The image data subjected to the image compression is immediately sent to the output buffer 2045. The output buffer 2045 performs handshaking with the image bus I / F controller 2041 and the image compression unit 2043 and transfers the image data to the image bus I / F controller 2041. The image bus I / F controller 2041 transfers the transferred compressed (or expanded) image data to each device on the RAM 2002 or the image bus 2008. Such a series of processing is repeated until there is no processing request from the CPU 2001 (when processing of the necessary number of pages is completed) or until a stop request is issued from this image compression unit (when an error occurs during compression and expansion). It is.

  The configuration of the image rotation unit 2030 is shown in FIG. The image bus I / F controller 2031 is connected to the image bus 2008 to control the bus sequence, control to set a mode or the like in the image rotation unit 2032, and timing to transfer image data to the image rotation unit 2032 Take control. The processing procedure of the image rotation unit is shown below.

  Settings for image rotation control are performed from the CPU 2001 to the image bus I / F controller 2031 via the image bus 2008. With this setting, the image bus I / F controller 2041 makes settings necessary for image rotation (for example, image size, rotation direction / angle, etc.) to the image rotation unit 2032. After performing the necessary settings, the CPU 2001 again permits image data transfer to the image bus I / F controller 2041. In accordance with this permission, the image bus I / F controller 2031 starts transferring image data from each device on the RAM 2002 or the image bus 2008. Here, the size is 32 bits and the image size to be rotated is 32 × 32 (bits), and when transferring image data on the image bus 2008, image transfer is performed in units of 32 bits ( The image to be handled is assumed to be binary).

  As described above, in order to obtain a 32 × 32 (bit) image, it is necessary to perform the above unit data transfer 32 times, and it is necessary to transfer image data from discontinuous addresses (see FIG. 13). ).

  The image data transferred by the discontinuous addressing is written in the RAM 2033 so that it is rotated at a desired angle at the time of reading. For example, if the rotation is 90 degrees counterclockwise, the first transferred 32-bit image data is written in the Y direction as shown in FIG. By reading in the X direction at the time of reading, the image is rotated.

  After the 32 × 32 (bit) image rotation (writing to the RAM 2033) is completed, the image rotation unit 2032 reads the image data from the RAM 2033 by the reading method described above, and transfers the image to the image bus I / F controller 2031.

  The image bus I / F controller 2031 that has received the rotated image data transfers the data to each device on the RAM 2002 or the image bus 2008 with continuous addressing.

  Such a series of processing is repeated until there is no processing request from the CPU 2001 (when processing of the necessary number of pages is completed).

  The configuration of the device I / F unit 2020 is shown in FIG. The image bus I / F controller 2021 is connected to the image bus 2008, and controls the bus access sequence and generates control and timing of each device in the device I / F unit 2020. In addition, control signals to the scanner 10 and the printer 20 are generated. The scan buffer 2022 temporarily stores the image data sent from the scanner 10 and outputs the image data in synchronization with the image bus 2008. The serial-parallel / parallel-serial conversion 2023 arranges the image data stored in the scan buffer 2022 in order or decomposes and converts the image data into a data width that can be transferred to the image bus 2008. The parallel-serial / serial-parallel conversion 2024 decomposes the image data transferred from the image bus 2008 or arranges the image data in order, and converts the image data into a data width that can be stored in the print buffer 2025. A print buffer 2025 temporarily stores image data sent from the image bus 2008 and outputs the image data in synchronization with the printer 20.

  The processing procedure at the time of image scanning is shown below. The image data sent from the scanner 10 is stored in the scan buffer 2022 in synchronization with the timing signal sent from the scanner 10. When the image bus 2008 is a PCI bus, when the image data is 32 bits or more in the buffer, the image data is sent from the buffer to the serial-parallel / parallel-serial conversion 2023 in the first-in first-out manner. Is transferred to the image bus 2008 through the image bus I / F controller 2021. When the image bus 2008 is IEEE1394, the image data in the buffer is first-in-first-out, sent from the buffer to the serial-parallel / parallel-serial conversion 2023, converted into serial image data, and then converted into serial image data through the image bus I / F controller 2021. Transfer on 2008.

  The processing procedure at the time of image printing is shown below. When the image bus 2008 is a PCI bus, 32-bit image data sent from the image bus is received by the image bus I / F controller, sent to the parallel-serial / serial-parallel conversion 2024, and the number of input data bits of the printer 20 Are stored in the print buffer 2025. When the image bus 2008 is IEEE 1394, serial image data sent from the image bus is received by the image bus I / F controller and sent to the parallel serial / serial / parallel conversion 2024 to determine the number of input data bits of the printer 20. It is converted into image data and stored in the print buffer 2025. Then, in synchronization with the timing signal sent from the printer 20, the image data in the buffer is sent to the printer 20 in a first-in first-out manner.

[Example 1]
In the following, sound output during jam processing will be described with reference to the flowchart of FIG.

  When a jam occurs, first, in step 1, jam position information is collected from a paper sensor in the machine, and the process proceeds to step 2.

  In step 2, the number of jam occurrence points is output from the audio output speaker 501 based on the jam position information collected in step 1, for example, “There are five jam occurrence points”, and the process proceeds to step 3.

  In step 3, the output information of each sensor is detected, and the movement is checked to see if there is no paper detection signal from all sensors. If it is determined that all the paper detection signals of the sensors have disappeared and the jam has disappeared, the process proceeds to step 6, and if the paper detection signal is output from the sensor, the process proceeds to step 4.

  In step 4, it is checked whether or not the front cover or the like is closed and all the door sensors or the like are reset to the correct state. If it has not been reset, the process returns to step 3 to check the output of the paper detection signal. If the jam is reset before it is completely processed, go to Step 5.

  In step 5, in order to inform the user that the jam has been reset before it has been completely processed, the number of remaining jams is output as a voice, and the process returns to step 3.

  Here, in the reset state, there is still a jam, so the engine of the copier is not turned on, and the sound output is started at the same time as all the door sensors become normal.

  In step 6, when all the jams have been lost, a voice is output, for example, “no more jams”, and the user is notified.

[Example 2]
Hereinafter, audio output during jam processing will be described with reference to the flowchart of FIG.

  When a jam occurs, first, in step 1-1, jam position information is collected from a paper sensor in the apparatus, and the process proceeds to step 1-2.

  In step 1-2, the number of jams in the machine is calculated, and the process proceeds to step 2. The method for calculating the number of jams will be described later.

  In step 2, the number of jams collected in step 1-1 is output as audio, for example, “the number of jams is 5”, by the audio output speaker 501, and the process proceeds to step 3.

  In step 3, the output information of each sensor is detected, and the movement is checked to see if there is no paper detection signal from all sensors. If it is determined that all the paper detection signals of the sensors have disappeared and the jam has disappeared, the process proceeds to step 6, and if the paper detection signal is output from the sensor, the process proceeds to step 4.

  In step 4, it is checked whether or not the front cover or the like is closed and all the door sensors or the like are reset to the correct state. If it has not been reset, the process returns to step 3 to check the output of the paper detection signal. If the jam is reset before it is completely processed, go to Step 5.

  In step 5, in order to inform the user that the jam has been reset before it is completely processed, the remaining number of jams and the jam location are output as voices, and the process returns to step 3.

  Here, in the reset state, there is still a jam, so the engine of the copier is not turned on, and the sound output is started at the same time as all the door sensors become normal. In step 6, when all the jams have been lost, a voice is output, for example, “All jams have been lost”, and the user is notified.

[How to calculate the number of jams]
Hereinafter, a method for calculating the number of jams will be described with reference to the flowchart of FIG.

When a job such as copy, printer, or fax starts,
In step 1, the controller unit 20 and the print engine unit 20 communicate to exchange information such as the paper size, paper interval, and number of pages, and the process proceeds to step 2.

  In step 2, the page request signal is counted and the process proceeds to step 3. The page request signal is a signal for the print engine unit 20 to request image information of the next page from the controller 30, and the counter 7131 in the beam detection sensor 713 is counted up.

  In step 3, it is monitored whether or not a jam has occurred. If a jam has occurred, the process proceeds to step 4, and if not, the process proceeds to step 6.

  In step 4, the number of jams is calculated. The number of jams in the machine is (number of pages transmitted from the controller 30 to the engine unit 20) − (number of sheets normally ejected to the outside of the machine), and can be obtained by the counter 7131-paper ejection counter 139. In step 4, because of a jam, the controller 30 is notified of which page is to be output again, the counter 7131 is set to the value of the paper discharge counter 139, and the process proceeds to step 5. Step 5 monitors whether the jam has been removed and reset, stays at step 5 until reset, and returns to step 2 when reset.

  In step 6, it is monitored whether or not the job has been completed (whether all pages have been output). If completed, the process proceeds to step 7, and if not completed, the process returns to step 2.

  In step 7, the counter 7131 is cleared and the process ends.
