When the image forming apparatus is in a recoverable abnormal state (for example, a jam or a door is open), the image reading operation and the facsimile transmission operation of the original by the facsimile function can be performed, but the copy operation by the copy function cannot be performed. If the first screen display control means invalidates the key operation when the numeric key is pressed after the program key is pressed, the number registered by pressing the numeric key is registered. The screen of the current copy mode is not displayed, and the user does not wastefully perform the key operation for starting the copy operation by the copy function, and the operability is further improved.

When the FAX function is in a fatal error state (for example, a communication error state or a hard disk error for SAF), a copy operation by the copy function can be executed.
Since the FAX transmission operation by the X function cannot be executed, the second screen display control means invalidates the key operation when any key of the FAX shortcut key group is pressed after the program key is pressed. , The pressed F
The screen of the FAX mode registered for the AX shortcut key is not displayed, and the user does not wastefully perform the key operation for starting the image reading operation of the original by the FAX function. Further improve.

When the digital copying system is in an unrecoverable fatal error state (serviceman call state), the copying operation by the copy function is also performed by the FAX function.
Since the AX transmission operation cannot be executed, the first or second screen display control means invalidates the key operation when any one of the ten keys or the FAX shortcut keys is pressed after the program key is pressed. Then, the copy mode screen registered for the number input by pressing the numeric keypad or the pressed FA
The FAX mode screen registered for the X shortcut key is not displayed, and the operator wastefully performs the key operation for starting the copy operation by the copy function or the image reading operation of the original by the FAX function. And the operability is further improved.

At the time of the copy operation by the copy function, since a new copy operation cannot be executed, the first screen display control means invalidates the key operation when the numeric key is pressed after the program key is pressed. Further, since the facsimile transmission operation can be executed at the time of the copy operation by the copy function, the second screen display control means operates the copy function when any one of the facsimile shortcut keys is pressed after the program key is pressed. After the copy operation is interrupted, a FAX mode screen registered for the key is displayed on the display unit. In this way, a malfunction or an erroneous operation can be prevented, and the operability is further improved.

During the image reading operation of the original by the FAX function, the image reading operation and the copying operation of the new original cannot be executed. Therefore, after the program key is pressed, any one of the ten keys or the FAX shortening key group is pressed. If the first or second screen display control means invalidates the key operation at that time, the copy mode screen registered for the number input by pressing the numeric keypad or the pressed FAX The FAX mode screen registered for the shortcut key is no longer displayed, and the operator wastefully performs the key operation for starting the image reading operation of the original by the FAX function or the copy operation by the copy function. And the operability is further improved.

In the user restriction mode using a password,
When any key of the facsimile shortcut key group is pressed after the program key is pressed, the second screen display control means displays a personal identification code input screen on the display unit, and when the personal identification code is input, By displaying the FAX mode screen registered for the pressed FAX shortcut key on the display unit, the key operation for setting the FAX mode registered in advance can be performed before the password code is input. Since it can be performed, the operability is further improved.

In this case, when a security code is input after a predetermined time has elapsed since the display of the security code input screen as described above, there is a high possibility that the input has been performed by another operator. If the initial screen of the FAX mode is displayed on the display unit, F
The screen in the AX mode is hardly displayed on the display unit, and the operability is further improved.

Alternatively, a password input screen is displayed on the display unit as described above, and when the password is input,
It is determined whether or not the FAX mode is registered for the pressed FAX shortcut key. If the FAX mode is not registered, an initial screen of the FAX mode is displayed on the display unit. improves.

In the user restriction mode using a password,
When the numeric key is pressed after the program key is pressed, the first screen display control means displays a password input screen on the display unit, and when the password is input, the first code is input by pressing the numeric key. By displaying the screen of the copy mode registered for the number on the display unit, the key operation for setting the copy mode registered in advance can be performed before the password is input, so that the operability is improved. Even better.

In this case, as described above, the personal identification code input screen is displayed on the display unit, and after a predetermined time has elapsed since the screen display, when the personal identification code is input,
Since the input is likely to have been performed by another operator, displaying the copy mode initial screen on the display unit may cause the copy mode screen not intended by the operator to be displayed on the display unit. Is almost eliminated, and the operability is further improved.

Alternatively, a password input screen is displayed on the display unit as described above, and when a password is input,
It is determined whether the copy mode is registered for the number input by pressing the numeric keypad, and if the copy mode is not registered, the initial screen of the copy mode is displayed on the display unit. Even better.

And other various operation keys.

Here, the keys directly related to the present invention among the respective keys will be briefly described. Each of the keys "0" to "9" of the numeric keypad 13 is used for setting a copy mode (program mode) to be registered or a copy mode to be called in addition to setting numerical values such as the number of copies (number of copies).

The program key 17 is used when registering or calling a program mode. The initial setting key 21 is used when performing initial setting. FAX shortcut keys of “01” to “28” of the FAX shortcut key group 22 are as follows.
It is used to assign a FAX mode (program mode) to be registered or a FAX mode to be called.

The image reading device 2 illuminates an original with a light source, and converts a reflected light image (image) of the original into a CCD (solid-state image sensor).
After reading the data and converting it into an electric signal (video signal), necessary image processing is performed.

The image forming apparatus 3 feeds image images sent from the image reading apparatus 2 or the like by electric signals using an electrophotographic system, a thermal system, a thermal transfer system, an ink jet system, or the like. , 4d to form an image on a sheet such as plain paper or thermal paper fed from one selected from those selected from the group consisting of:

The system control layer 5 controls each resource via a device control layer (not shown). Here, in order to configure a multitask type system, it is necessary to treat functional units as resources and perform management for sharing one resource with a plurality of applications. This management is performed by the system control layer.

The copy application 7 performs a copy operation using both the image reading device 2 and the image forming device 3. That is, the image of the document is read by the image reading device 2, and the image is formed on a sheet by the image forming device 3. The printer application 8 includes the image forming device 3
(Actually using a facsimile communication device not shown) to perform a facsimile reception operation and a print operation. That is, an image image transmitted from an external device by an electric signal is received by facsimile, and the image forming apparatus 3 forms an image on a sheet.

The FAX application 9 uses the image reading device 2 (actually also uses a FAX communication device not shown).
A document image reading operation and a fax transmission operation are performed. That is, the image of the document is read by the image reading device 2, and the image is faxed to the outside by an electric signal.
Send. Since the applications 7 to 9 are software, the resources cannot be operated directly. However, for convenience of explanation, such applications are described in such expressions.

FIG. 5 is a block diagram showing a specific example of the control section of the digital copying machine. The system control layer 5 includes a system controller 30, which controls the entire apparatus as a whole,
An operation section controller 31 for controlling the operation section 1, an image reading apparatus controller 32 for controlling the image reading apparatus 2, an image forming apparatus controller 33 for controlling the image forming apparatus 3,
And a peripheral controller 34 for controlling peripherals (not shown).

The input / output controller 35 of the device control layer
Is to drive and control mechanical input / output units such as clutches, sensors, and motors in order to actually operate the apparatus in accordance with logical instructions such as commands and control signals from the system control layer 5.

FIG. 6 is a block diagram showing an example of a connection relationship between the system unit 6 of FIG. 3 and the copy application 7, the printer application 8, and the FAX application 9. In this digital copying machine, each unit in the system unit 6 is connected to a copy application 7, a printer application 8, and a FAX application 9 by a control signal line 41. Also, the system unit 6
Operation unit 1 and copy application 7, printer application 8, F
The AX application 9 is connected to the image reading device 2 and the image forming device 3 in the system unit 6 by the operation unit control bus 42, and the copy application 7, the printer application 8, and the FAX application 9 are connected by the image forming signal bus 43, respectively. I have.

In this digital copying machine, as shown in FIGS. 3 and 6, a CPU (central processing unit) is provided for each application, and a system control layer 5 and a device control layer (see FIG. 5) are provided as one. Although it is controlled by CPU, each application, system control layer 5, and each resource have a CPU,
Logical instructions from the system controller 30 shown in FIG. 5 to each of the other controllers 31 to 35 may be transmitted through the control signal line 41.

Although an operation section control bus 42 for controlling the operation section 1 is provided, it is naturally conceivable to control the operation section 1 by exchanging logical instructions using the control signal line 41. . As described above, since the system hardware configuration can be freely configured, the description of FIGS. 3 and 5 is a conceptual description without limitation.

Next, an example of using resources during operation by an application will be described with reference to FIGS. As shown in FIG. 7, the system control layer 5 provides a function such that virtual resources exist individually in all applications when viewed from the application layer. With this function, it is not necessary to manage the system state in the application layer, and all the applications can be managed in the system control layer 5 under the same conditions.

That is, the application sends a use request to the system control layer 5 when a resource to be used occurs.
The system control layer 5 sends the result to the request source application by judging from the resource usage status at that time. The request source application determines whether or not the application can be executed based on the result, and executes the application if possible. Basically, execution right management is performed by the same procedure.

In the system of FIG. 3, there is only one resource. For this reason, in the system control layer 5, when virtual resource use requests for each application conflict, it is necessary to perform exclusive control or time division allocation in order to pass the actual resource use right. Whether to perform exclusive control or time-division allocation depends on the type of resource and user settings. A supplementary explanation will be given with reference to FIGS. 8 and 9. The resources enclosed by the broken lines are virtual resources, and the resources encircled by the solid lines have no execution (display in the case of the operation unit) right. Is shown.

FIG. 8 shows an interleaving operation between the copy application 7 and the printer application 8. Here, in a normal digital copying machine, for example, a printing operation is performed in a function unit (= job unit) so that the printing operation is switched to a printing operation by a printer application after a printing operation by a copy application is completed. On the other hand, inserting a print operation of another job into a print operation of one job is called “interleaving”.

The copy application 7 is executing with all the execution rights of the resources, that is, the operation unit 1, the image reading device 2, and the image forming device 3. At this time, when a request to use the image forming apparatus 3 is sent from the printer application 8, if the interleave mode is set to be executable by user setting, the system control layer 5 controls the image forming apparatus 3 to perform time division allocation control. Perform

The time division allocation control dynamically changes the execution right of a resource among a plurality of applications. As a result, the output (print result) of the image forming apparatus 3 is a mixture of the output by the copy application 7 and the output by the printer application 8. During the output, the image forming apparatus 3 can be changed without being stopped, so that the waiting time between the two can be minimized.

FIG. 9 shows the parallel operation of the printer application 8 and the FAX application 9. The FAX application 9 operates, for example, when the operation unit 1 and the image reading device 2 are used in a FAX transmission mode or the like, and the printer application 8 operates when only the image forming device 3 such as performing a printing operation is required.

Therefore, even if the printer application 8 and the FAX application 9 request resources at the same time, there is no need for exclusive or time-division allocation since resource contention does not occur, and it is possible to accept requests from both applications. is there.
Therefore, the operations of the printer application 8 and the FAX application 9 can be performed at the same time (in parallel).

Next, regarding communication between the system controller 30 and each unit or application, serial communication, parallel communication, or the like can be considered as a communication handshake. Here, serial communication will be described as an example.

As the serial communication protocol, in this embodiment, transmission speed = 9600 bit / s, synchronization method = start-stop synchronization (asynchronous), data length = 8 bits, start bit = 1 bit, stop bit = 1 bit, parity bit = Defines an odd number.

Transmission and reception are performed on a frame-by-frame basis. As a means for error recovery in communication, when a receiving station receives a frame, it receives ACK (Acknowledge) and NAK (Non-Acknowledg).
e) Notify either of them to the transmitting station. The transmitting station has an ACK
, The other station recognizes that the frame has been normally received.

On the other hand, if NAK is received, it is assumed that an error on the line (for example, parity error, framing error, etc.) has occurred, and the communication frame is retransmitted. Naturally, even after a certain period of time (here, 300 ms)
If neither ACK nor NAK can be received (when a time-out error occurs), the partner station determines that there is no response and retransmits. If ACK is not received even after performing retransmission several times (here, four times), it is determined that the partner station is abnormal.

In this embodiment, the data frame uses an ASCII character string (H'20 to H'FF).
Further, control data such as ACK and NAK are H'00 to H'00.
It is allocated to the area up to H'1F. Specifically, A
CK = H'04 and NAK = H'05. FIGS. 10 and 11 show state transition diagrams of this communication. In the figure, BFL is a control code (specifically, BF) for the other station to notify the reception buffer of a full state.
L = H'03).

Next, the operation procedure by the user when registering the copy mode and the processing operation by the system control layer 5 (system controller 30) will be described with reference to FIGS.
