Abstract

PURPOSE:To automatically restart the working of a facsimile equipment after a fault is recovered by preparing an application program divided into plural phases and starting the execution at a phase analyzing routine at the rise of a system. CONSTITUTION:A main control part 20 is provided with an application program divided into plural phases for execution of a phase analyzing routine 100, the phase executing routines 200-240, and the phase updating routines 300-340. Then the part 20 executes repetitively the routine 300 to write the value of the phase to be executed next and a parameter into a nonvolatile memory 4 at the end of each phase and the routine 100 to decide the program to be executed next based on the phase value written in the memory 4. The part 20 starts the execution at the routine 300 at the system rise. As a result, the operation interrupted by a service interruption, etc., can be automatically restarted at the recovery of the fault.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a facsimile machine that is capable of immediately resuming an operation interrupted due to a failure such as a power outage upon recovery from the failure.

(Prior Art) Few conventional facsimile machines have non-volatile memory, and even those that do have non-volatile memory can be used as speed dials. It was only used as a means of holding static data such as IF3 and device parameters.

For this reason, for example, when executing an application computer operation such as inputting read image information to a disk file for broadcast transmission and then transmitting the image information to multiple designated destination terminals, the image information If the application program is reset due to a power outage etc. during transmission, the process will not continue.
It had to remain suspended.

(Problem to be Solved by the Invention) As described above, in the above-mentioned conventional facsimile machines, non-volatile memory is not used as a program control area, so when a power outage occurs, the operation being executed is simply interrupted. There was a problem that the operation could not be continued after that.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a facsimile machine that can automatically resume operations that have been interrupted due to the occurrence of a failure such as a power outage upon recovery from the failure.

[Structure of the Invention] (Means for Solving the Problems) The facsimile device according to this section includes a nonvolatile memory, and a control unit that controls the operation of the entire device including an internal read operation of the nonvolatile memory. , an application program that is divided into a plurality of phases regarding the control operation of the control unit, and the control unit calculates the value of the next phase to be executed and the execution of the phase upon completion of each phase. The application program is executed while repeating a phase update routine that adds necessary parameters to the non-volatile memory, and a phase analysis routine that determines the next program to be executed according to the phase values written in the non-photosensitive memory. The present invention is characterized in that when the system is started up, execution is first started from the phase analysis routine.

(Function) According to the facsimile apparatus of the present invention, when the system is about to start up due to recovery from a failure such as a power outage, the phase analysis routine is first executed. Since the phase value is held in non-volatile memory, even after recovery from a fault, the phase corresponding to that value, that is, the phase that was updated immediately before the fault R1, is moved to and the corresponding location ■! can be restarted automatically.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a block diagram showing the configuration of a facsimile apparatus according to an embodiment of the present invention. A non-volatile memory 4 having a battery section 3 is provided.

Here, the facsimile main body 2 includes a main control section 20 that controls the operation of the entire apparatus including the Hj reading operation of the non-volatile memory 4, a panel section 21 that is controlled by this main control section 20, and a scanner. It has a normal configuration including an f/a section 22, a file section 23, and a transmission section 24.

Next, FIG. 2 shows the control tIII in the facsimile machine of the present invention.
! As an example of a processing routine created by IJ, this figure shows the overall flow of the I18 routine when applied to a broadcast transmission operation.

As is clear from the figure, the processing routine of the present invention includes a phase analysis routine 100 and a phase execution routine 2.
00 to 240, and phase update routines 300 to 340. In executing these series of processing routines, the main and subflu unit 20 includes a phase execution routine 200.
A plurality of phases (phase O
- Phase 4) An application program divided into phases 4) is prepared.

Hereinafter, processing operations related to broadcast transmission in the facsimile apparatus of the present invention will be described in detail with reference to the flowcharts of FIGS. 3 to 7.

Normally, the program is in a state awaiting Phase O operations.

To reach this state, the phase solution 1i routine 100 performed immediately before
The details of the processing of this phase analysis routine 100 are shown in FIG.

That is, in this phase analysis routine 100, the main control unit 20 reads the phase value written in the processing up to that point from the nonvolatile memory 4 (step 101), and determines whether the value is between 0 and 3. (Step 10)
2-105).

Then, in step 102, when it is determined that the phase value is 0, a transition is made to a state (200>) of waiting for the operation of phase O corresponding to that value.

The details of the processing in this operation waiting state (200) are as shown in FIG. It is determined whether or not (step 201).

When the desired input is obtained here, the main control unit 2
0 moves to the phase update routine 300, updates the phase value from 0 to 1 to specify the next phase to be executed according to the flow shown in FIG.
(step 301).

After updating the phase value in this manner, the main control unit 20 returns to the phase analysis routine 100 again.

Here, as in the previous step, read the phase value from the nonvolatile memory 4 and recognize the value (steps 101 to 105).
, depending on what that value is, it moves to the phase with the corresponding value.

From the flow of operations described above, in this process step 10
In step 3, it is determined that the phase value is 1, and based on the recognition result, the process moves to phase 1 file input state 1 (210>) corresponding to that value.

The state of this file input! (For details of the processing at 210>,
It is shown in FIG.

That is, in this file input process, the main control section 20 drives the scanner section 22 and sequentially stores the image information of the read document in the file section 23 (step 211) t...
The process is monitored until the accumulation is completed (step 2
12).

Then, when the completion of accumulation is recognized by Tlf in step 212,
Next, the main control unit 20 moves to a phase update routine 310, and executes the previous phase update routine 300 shown in FIG.
Similarly, in order to specify the next phase to be executed, the phase value is updated from 1 to 2 and written to the nonvolatile memory 4 (step 301) a. After the phase value has been updated in this way,
The main control unit 20 returns to the phase analysis routine 100 again.

Here, the phase value is read from the non-volatile memory 4 and the value is changed to 591 in steps 101 to 105 as in the previous step.
), depending on what that value is, it moves to the phase with the corresponding value.

From the flow of operations described above, in this process it is step 1.
At step 04, it is recognized that the phase value is 2, and based on the recognition result, a transition is made to the state (220) of file transmission (2) of FUEZ2 corresponding to that value.

The details of lI8 raccoon in this file transmission state K (220) are shown in FIG.

In other words, in the process of file transmission (■), the main control unit 20
reads the image information from the file section 23 and starts transmitting it to the first destination terminal through the transmitting section 24 (step 221), and continues the processing until the transmission is completed (step 222).

Then, in step 222, the transmission ends with M! If it is recognized, the main control unit 20 then moves to a phase update routine 320, updates the phase value from 2 to 3, and writes it to the non-volatile memory 4 in the same manner as the previous process (FIG. 5). (step 301).

After that, the main control unit 20 restarts the phase analysis routine 10.
0 and performs the process shown in FIG. 3. In step 105, it is determined that the phase value is 3, and the process moves to the phase 3 file transmission state (230) corresponding to that lead.

This file transmission process (2) is also executed according to the flow shown in FIG. 4'A.

Thereafter, the phase value is similarly updated from 3 to 4 in the phase update routine 330, and the process moves to the phase 4 file transmission state (240) via the phase analysis routine 100.

Here, the main control unit 20 transmits the image information read from the file unit 23 to the third destination terminal through the transmission unit 24, and then updates the phase value from 4 to 0 in the phase update routine 340, and further updates the phase value from 4 to 0. Based on this, the process returns to the phase O operation waiting state (200>) via the phase analysis routine 100.

In the processing routine of the present invention, for example, even if a power failure occurs during the execution of file transmission n (230) in phase 3, the value f? Since the data remains in the non-volatile memory 4 until after the power is restored, by setting it to start operation from the 71-Z analysis routine 100 at system startup, the data will be saved from the non-volatile memory 4 after the power is restored. Based on the read phase value, the process immediately shifts to phase 3, and the file transmission process (2) can be restarted.

In the above embodiment, only the example of application to the broadcast transmission operation was described, but the facsimile machine A can also be used for multi-copying using the file section 23, outputting a communication journal, etc.
Needless to say, the present invention can be applied to various functional operations in the equipment.

【Effect of the invention〕

As explained above, according to the facsimile device of the present invention, an application program divided into multiple phases is prepared, and each time each phase ends, a value corresponding to the next phase to be executed is written into the nonvolatile memory. The above application program is executed by repeating the phase update routine and the phase analysis routine that moves to the corresponding phase according to the phase value in the non-volatile memory, and when the system is started up, execution is first started from the phase analysis routine described in +IJ. Therefore, even if the operation being executed is interrupted due to a failure such as a power outage, the phase analysis routine can be performed using the phase stored in the non-volatile memory at that time as an index after recovery from the vI5 damage. This has the great advantage of being able to transition to the updated phase as soon as a failure occurs and restart the process on its own.
