2 is the H of the image data of all original images (three in this example)
After the writing to the D113 is completed, the image data management information in the main body memory 101 is also written to the HD113.
It communicates with the HD control unit 112 via the CPU communication I / F 111. On the other hand, the main body control unit 100 measures the time during which the image data written to the image memory 109 is written to a size at which printing can be started, and when the time reaches the time, the main body control unit 100 Then, an image print output start is issued, and the image data in the image memory 109 is sent to the laser unit 105 and the image forming unit 106 via the image data selector 104 to perform print output.

The print of the first copy for the set number of 5 is performed on the image data sent from the image processing unit 103 to the image memory 109 as described above. For the remaining number of copies thereafter, the main body control unit 122
2 and reads out the compressed image data from the HD 113 in accordance with the recording order.
Performs expansion processing of compressed data in the image memory 10.
Expand to 9. After expansion to the image memory 109, control is performed in the same manner as printing of the first copy.

Next, the image data management operation performed by the image data management unit 122 will be described.

There are three types of image data in this embodiment: image data that becomes invalid after the job is completed, image data that is valid until deleted by the user, and image data that becomes invalid after a certain period of time after registration. , And the following jobs are called temporary jobs, permanent jobs,
It is called a timer job. These image data are compressed as described above in HD (hard disk)
113.

When recording image data on the HD 113,
When the use of the image forming apparatus is started, it is possible to secure and record a continuous area of the image data in the order of registration. However, when the image data becomes invalid and
Even if the original image size is the same, H
Since the size of the data recorded in the D113 differs for each image, a situation occurs in which a continuous area cannot be secured on the HD 113 at the time of image registration while image data registration / deletion is repeated. To avoid this problem,
A mechanism for handling the divided and recorded data on D113 collectively as one image data is required.

The minimum unit of data handling in the HD 113 is a sector. In the present embodiment, when the HD control unit 112 writes / reads data to / from the HD 113, processing is performed in sector units. However, in the case of handling relatively large-sized data even after compression processing, such as image data,
The unit of a sector is too small, and the degree of dispersion of the data as described above is extremely high, and the overhead of processing at the time of data access is large.

Therefore, in the present embodiment, a group of several consecutive sectors is newly defined as a block, and the image data is handled in the HD 113 in units of this block (image block). By doing so, the distribution of data is suppressed, and the processing overhead at the time of data access can be reduced. The block size is arbitrary, but if the block size is set too small, the degree of data distribution increases, and if the block size is set too large,
The storage area not used in the block increases.

Although it has been described that one image data is managed by a plurality of image blocks, from the viewpoint of a job defined by a series of prints related to each other, one image data is managed. Corresponds to one page of the job. Therefore, one job is composed of one or more pages, and one page is composed of one or more image blocks. Further, in the present embodiment, a job is a temporary job that is invalidated after the job ends, a permanent job that is valid until deleted by the user, The image data management unit 100 classifies and manages any of the timer jobs that become invalid after a lapse of time.

Next, with reference to the flowcharts of FIGS. 3 and 4, a description will be given of the processing operation of the image data management unit 122 relating to the registration of image data according to the present embodiment.
The details will be described step by step.

First, reference is made to FIG. First, the image data management unit 122 waits for a job registration request to be issued from the main body control unit 100 (step S001), and upon receiving the job issuance request, whether the job is a new job or has already been registered. It is determined whether the job is a completed job (step S002). The job issuance request includes the type of job, whether the job is a new job or not, the page number of the image data in the job, and, for a timer job, the axial direction such as a set value of a valid time length of the job. Have been.

If it is determined in step S002 that the job is a new job, it is checked whether or not the new job can be registered (step S003). In the image forming apparatus of the present embodiment, since the upper limit of the number of jobs that can be registered is set for each type of job, registration of a new job is not performed for a job of the type whose registration number has already reached the upper limit. Can not.

If it is determined in step S003 that registration is possible, the remaining amount of usable image blocks is checked (step S004). The maximum value of the data size after compression (data size in the worst compression ratio) can be calculated from the image size. If the number of free image blocks that can record the size cannot be secured, the image data is You cannot register.

If a free image data block has been secured (step S005), the job is registered (step S006). The registration time of the job at that time is initialized to an appropriate value.

On the other hand, if it is determined in step S002 that the job is a registered job, the remaining amount of usable image data block size is checked (step S007), as in step S004, and an empty image data block can be secured. If (step S008), the processing is continued.

If it is determined in step S003 that job registration is not possible, or if it is determined in step S005 or S008 that a free image data block cannot be secured, the image data management unit 12
No. 2 determines that there is no free space in the hard disk 113 (disk full) (step S009), and ends the processing.

After the job is registered in step S006, or when a free image data block is secured in step S008, it is determined whether or not the page to be registered is a new page (step S01).
0).

If it is determined in step S010 that the page is not a new page, the image forming apparatus according to the present embodiment does not support page overwrite registration.
The image data management unit 122 determines that there is page overlap (step S011), and ends the processing.

Next, reference is made to FIG. Step S0 above
After it is determined in step 10 that the page is a new page, the page is registered in the job and the secured image data block is registered in the page (step S012).

After the transfer of the image data is started, the end of the writing of the image data into the image data block is waited (step S013). When the writing of the image data block is not completed yet (step S014). Then, the image data block is secured again (step S015), and the secured image data block is added to the page (step S016). Since the remaining amount is confirmed at the worst size of the compression ratio for the image data in step S004 or S007, an empty image data block can be reliably secured in step S015.

Thereafter, the flow returns to step S013 to continue writing the image data.

If it is determined in step S014 that the writing of the image data has been completed, the registration time of the job is recorded (step S017), and the process ends.

Next, the flow of processing of the image data management unit 122 when the power of the image forming apparatus of this embodiment is turned on will be described with reference to FIGS.

Referring first to FIG. First, a device check of the hard disk 113 is performed (step S10).
1). If the hard disk 113 is not normal, that is, if the hard disk 113 cannot be detected or a device error has occurred, the process ends (step S102).

Subsequently, the device parameters of the hard disk 113 are set (step S103), and the keyword sector of the hard disk 113 is read out to the main memory 101 (step S104). The read keyword data is checked, and if inappropriate, the process is terminated (step S105). The keyword sector is a sector having a certain characteristic set in advance. If the system keyword written in this keyword sector is appropriate (normal), the detected hard disk 113 Recognize that it has been initialized for the system.

Next, the image data management unit 122 transmits the first management information from the hard disk 113 to the main memory 101.
The first management information is read out (step S106), and the validity of the first management information is evaluated (step S107). If it is determined that the first management information is appropriate, the first management information is written to the storage area for the second management information on the hard disk 113 (step S108). Here, the validity of the first management information is determined based on the match / mismatch of the check flags added to the beginning and end of the management information. The check flag is updated every writing, and the value of the first check flag and the value of the last check flag of the first management information match. Therefore, if the values of the first and last check flags match as a result of reading the first management information, the writing of the first first management information has been completed normally, and Do not match, it means that the power has been turned off during the writing of the first management information, and it can be seen that the writing has not been completed normally.

If it is determined in step S107 that the first management information is not valid, the image data management unit 1
22 reads the management information from the second management area of the hard disk 113 (step S109), and writes the read second management information to the first management area on the hard disk 113 (step S110).

Next, reference is made to FIG. Step S above
After the end of step 108 or step S110, the image data management unit 122
It is checked whether the registration of the job has been completed (Step S111, Step S112, Step S11
3) The job whose registration has not been completed is deleted (step S114).

Thereafter, the registered temporary job is set based on the setting of the processing related to the registered temporary job at startup recorded in the main body memory 101 (steps S115 and S11).
6), erase (step S117), request the main body control unit 100 to print out after the main body weight (step S118), or move from the temporary job to the timer job (step S119), The start-up process of step 122 is completed.
