An 8-bit digital signal is output to the printer unit 6000 instead of the signal. Reference numeral 2501 denotes a selector which outputs image data read by the CCD and passed through the A / D converter 2502, the black offset corrector 2503, and the shading corrector 2504 to the line memory 2505 or the CPU 2500.
Switch to 200.

The operation of each section will be described below.

The two original images placed on the original platen glass surface 2 are scanned by the original scanning system 2100 and input to the CCD arranged in the image sensor unit 9. First, an electric signal (analog) corresponding to the density of a pixel sequentially sent from the CCD is converted into a digital signal of a level corresponding to the density by an A / D converter 2502. After that, the black offset correction unit 2503 corrects the variation in the offset in the black density of the CCD analog amplification unit, and the shading correction unit 2503 corrects the variation in the light amount distribution of the original illumination lamp. Next, the shading correction unit 25
03 is temporarily stored in a line memory (storage device) 2505.

The original position recognizing unit 2507 uses the signal after the shading correction to recognize the position of the original on the original platen, and changes the magnification / movement processing unit 250.

Further, the trim / mask / negative / positive processing unit 2510 inverts the level of the digital signal to a negative /
Positive processing, a signal in a designated area or a signal outside the area is changed to a designated density level to perform trim processing or mask processing, and an add-on processing unit 2511 operates a memory in which character information is stored in advance. Then, the information of the designated character is read, and an 8-bit digital signal is transmitted to the designated portion at the designated portion instead of the image signal to the printer portion 6000. The printer portion 600 transmits a laser based on the digital signal transmitted from the image processing portion 2500. Is turned ON / OFF to reproduce a bright portion and a dark portion on the photosensitive drum.

The scanner unit 2000 includes a RAM 2300 as an image memory for storing document image information for a plurality of pages, and stores a document image scanned by a CCD and image data transferred from a host computer. Used to store. For example, when the copying apparatus is operating in a remote control mode from an external device, image data sent from the external device via the LAN interface unit 3000 is transmitted to the CPU 4100 and the CPU 2200 of the control unit 4000 by the CPU 4100 and the CPU 2200.

The bitmap data in the RAM 2300 is stored in the printer unit 6
000 directly.

Further, the CPU 4100 of the control unit 4000
Is transferred to the line memory 2505 when the command transferred from the MFP includes an image processing operation based on an image processing mode set by the operation unit 1000 or an external device and stored in the RAM 4300 of the control unit 4000. , The specified image processing is executed.

After the image data read by the CCD is sequentially processed by the image processing unit 2500, the image data is transferred and stored in the RAM 2300 as an image memory, and the image data is transferred to the CPU 4100 of the control unit 4000 and the L
The data can be transmitted to an external device via the AN interface unit 3000. In this case, the selector 250
1 is switched to channel 2 and the analog signal from the CCD is transferred to the CPU 2200 via the A / D converter 2502, the black offset correction unit 2503, the shoeing correction unit 2504, and the selector 2501. CPU
Reference numeral 2200 sequentially stores data transmitted from the selector 2501 in an appropriate area in the RAM 2300 based on scanning position information in the original scanning system 2100 which is an optical scanning unit.

Further, after the end of scanning, the CPU 2200 notifies the CPU 4100 of the control unit 4000 of the end of scanning. The CPU 4100 of the control unit 4000 is the CPU 220
Then, the image data receiving request command in the RAM 2300 is transmitted to the external device 0, and the image data transmitted from the CPU 2200 is transmitted to an external device via the LAN interface unit 3000.

As described above, the image forming apparatus functions as a digital printer, a digital document scanner, and a stand-alone digital copying machine as peripheral devices of an external device. Switching control to each function is performed based on a control command transferred from an external device or an operation mode selection operation input from the operation unit 1000.

Hereinafter, the image output processing operation of the image forming apparatus according to the present invention will be described with reference to the flowcharts of FIGS.

FIGS. 5 and 6 are flowcharts for explaining an image output processing procedure of the image forming apparatus according to the present invention.
It is executed by CPU 4100 based on a program stored in ROM 4400 of control unit 4000. In addition,
(1) to (14) show each step.

First, it is checked whether there is a new request (reservation setting of image processing mode) from the host computer via the operation unit 1000 or the LAN interface unit 3000 (1), and the new request (reservation setting of image processing mode) is checked. ), It is determined whether the queuing of the output request JOB still remains (that is, the image processing mode in which the image has not been output yet is stored in the RAM 4300).
Is determined (4) or not (4). If it is determined to be left, the process proceeds to step (5), and if it is determined that there is no remaining, the process proceeds to step (14).

On the other hand, if it is determined in step (1) that there is a new request (image processing mode reservation setting), the new request (registration) is analyzed (reserved image processing mode is analyzed). , Output number, image information signal,
The data such as the priority order is reconstructed to create new request JOB data (2). Next, the new request job data reconstructed in step (2) is linked to the queuing of the output request job (3). That is, the newly set image processing mode is stored in the RAM 4300 together with the previously set image processing mode as queue structure data.
Is stored in

Next, it is checked whether or not there is a request to delete a registered JOB (deletion (cancellation) setting of a reserved image processing mode) (5). If it is determined that there is a processing mode deletion setting), the image processing mode is deleted (canceled) by disconnecting the job requested to be deleted from the queuing of the output request job (6), and the process proceeds to step (1). Return.

On the other hand, if it is determined in step (5) that there is no request to delete the registered JOB (deletion (cancellation) setting of the reserved image processing mode), the registered job is deleted. It is checked whether or not there is a correction request (correction setting of the reserved image processing mode) (7), and when it is determined that the correction request is not (correction setting of the reserved image processing mode), Proceed to step (9).

On the other hand, if it is determined in step (7) that there is a request for correcting a registered JOB (correction setting of the image processing mode set as a reservation),
The job requested to be corrected is temporarily separated from the queuing of the output request job, and the job data is corrected in accordance with the correction request (reserved image processing mode correction setting).
The output request is linked to the queuing of the job again (8).

Next, all the jobs (reserved image processing modes) that are linked to the queuing of the output request job are checked, and a high priority job (image processing mode) is set by setting the output request time and the management effective time. Mode), the reservation of the image processing mode for which the management valid time has elapsed is invalidated (disconnected from the queue of the output request job), the timer of the queuing job is updated (9), and the search is performed in step (9). It is determined whether there is a high priority job (image processing mode) (10), and if it is determined that there is a high priority job (image processing mode,
Output processing for one image output of JOB (image processing mode) with a high priority is performed (11), and the process proceeds to step (13).

On the other hand, if it is determined in step (10) that there is a job (image processing mode) having a high priority, the image output for one image output of the job (image processing mode) queued first. Output processing (12),
Proceed to step (13).

Step (11) or Step (12)
Subtracts one output image from the total number of output images for the job (image processing mode) output in (1).
3). When the job (image processing mode) ends with the output image, the job is disconnected from the queuing, the image processing mode is deleted, and step (1) is performed.
Proceed to 4).

Next, the output request queuing is empty (the image processing mode in which the image has not been output yet is RA
(Stored in M4300) or not (14). If the output request queuing is empty, the process ends. If the output request queuing still exists, step Returning to (1), the processing is performed again.

Note that, as a timing for starting the processing operation shown in the flowchart, the operation is started when a new output request is registered (the image processing mode is reserved). However, this does not apply if it is already running.

Hereinafter, referring to the flowchart of FIG.
A reservation processing operation of the image forming apparatus according to the present invention will be described.

FIG. 7 is a flowchart for explaining the image processing mode reservation processing procedure of the image forming apparatus according to the present invention. The JO executed by the CPU 4100 based on the program stored in the ROM 4400 of the control unit 4000.
It corresponds to B reservation, correction and deletion processing. In addition, (1)-
(16) shows each step.

First, when a reservation setting key 5050 on the operation unit is input or a request for image processing mode reservation setting or the like is input from the computer via the LAN interface unit 3000, the input request content is changed to the image processing mode. It is determined whether or not a mode reservation setting process is performed (1). If the request content is determined to be a reservation setting process in the image processing mode, a password (password) for making a reservation or a user name (or user ID) is set. User input is performed from the operation unit 1000 or the host computer (2), and thereafter, the user performs reservation setting of the image processing mode (setting of the number of sheets, image forming mode, output paper, etc.) (3).

Next, an input as to whether or not to set the completion time is displayed on the LCD 1100 of the operation unit 1000 or the display unit of the host computer to urge the user, and whether to set the completion time based on the user input is determined. It is determined whether or not it is (4). If it is input that the completion time is not set, the process proceeds to step (6), and if it is input that the completion time is set, the time of the output completion time is set (5). Here, the time setting is, for example, a mode in which the output is not required to be performed immediately, but the time is set such that the output is completed by a certain time.

Next, the user is prompted to input whether or not to set the valid time, and it is determined whether or not to set the valid time based on the user input (6). If it is input that the effective time is not set, the process proceeds to step (8). If it is input that the effective time is set, the effective time is set (7). Here, the valid time setting means that if the user can output within a certain period of time, the user wants to output it, but otherwise does not need to output it (invalidating the reservation setting of the image processing mode). This setting is made.

Next, the reservation job data is constructed based on the set image processing mode, the image output processing task shown in FIGS. 5 and 6 is started (if not already started), and a new reservation is made. A request is made to the image output processing task (reservation registration) (8), and the processing ends.

On the other hand, if it is determined in step (1) that the input request content is not the reservation setting process of the image processing mode, the input request content is set in the reservation-set image processing mode (reserved registration). Judgment (JOB) is determined (step 9). If it is determined that the image processing mode (reserved and registered job) is to be deleted, the reservation is deleted (canceled). ) The user inputs a password (password) or a user name (or user ID) for performing the process (10). By inputting the password or the user name, it is possible to prohibit another user from performing the reservation deletion (cancellation) processing.

Next, the reserved image processing mode (JOB information) is displayed on the LCD 1100 as a display unit of the operation unit.
(Or a display unit on the host computer side), and the user selects and sets an image processing mode to be deleted (cancelled) (when there are a plurality of image processing modes (JOBs) set in advance) (11). A request for deletion of the image processing mode (JOB) is made to the image output processing task shown in FIGS. 5 and 6 (deletion registration) (12), and the processing is terminated.

On the other hand, in step (9), the input request contents are reserved and registered in the image processing mode (JOB).
If it is determined that the request is not a deletion (cancellation) process, it is determined whether or not the request content is a correction process of a reservation-registered image processing mode (JOB) (13), and is determined to be a reservation correction process. If so, the user inputs a password (password) or a user name (or user ID) for performing the reservation correction process (14). By inputting the password or the user name, it is possible to prohibit another user from performing the reservation correction process.

Next, the image processing mode (JOB information) set as the reservation is displayed on the LCD 1100 which is the display unit of the operation unit.
(Or a display unit on the host computer side), and the user selects and sets an image processing mode to be corrected (when there are a plurality of reserved image processing modes (JOB)) (1).
5), a request for correction of the selected image processing mode (JOB) is made to the image output processing task shown in FIGS. 5 and 6 (correction registration) (16), and the processing ends.

On the other hand, if it is determined in step (13) that the input request content is not the correction process of the job registered in the reservation, the process ends.

With the above processing, the image forming apparatus can be set for reservation, deletion (cancellation), and correction by remote processing via the operation unit 1000 or the LAN interface unit 3000, and the efficiency can be improved according to the priority. I can work well.

In step (13) shown in FIG.
When the job (image processing mode) ends with the output image, a mail indicating that the job (image processing mode) has ended is sent to the name (image processing mode) input in steps (2) and (14) of FIG. Is returned to the user of the host computer that has set the reservation (or the operation unit 100).
0 (displayed on the LCD 1100) can be easily achieved.

As a result, the user can recognize the end of the output of the reserved image without constantly monitoring the end of the image output.

Step (9) shown in FIG. 5 and FIG.
In the case where the reservation of the image processing mode after the management valid time has been invalidated, a mail indicating that the reservation of the job (image processing mode) has been invalidated is sent to the name (step S10) of FIG. It is also possible to easily achieve a control for returning (or displaying on the LCD 1100 of the operation unit 1000) a reply to the user of the host computer that has set the image processing mode for reservation.

As the timing for starting the processing operation shown in the flowchart, the operation is started when processing such as reservation setting of an image processing mode is performed by the host computer or the like via the operation unit 1000 or the LAN interface unit 3000. .

In the reservation processing in the image processing mode shown in the flow chart of FIG. 7, the user is required to input personal identification data or reservation data as identification data, and input the personal identification data or reservation data. In this example, the password and the reservation data of the image processing mode are collated with the password or the reservation data input when the image forming mode is set to reserve the image forming mode. User name data is input by the user, the entered password data and the name of the reserved person are collated with the password data and the reserved person name data entered at the time of setting the image forming mode reservation, and the reservation of the image processing mode is corrected.
You may comprise so that permission of reservation deletion may be determined.

As a result, it is possible to reliably prevent the user from erroneously canceling, modifying, changing, or deleting the image processing mode set by another user.

Further, by setting the output time, it is possible to form an image preferentially according to the user's intention or prioritize other image formation.
