Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a statement m creation device that executes initialization processing in parts.

(Prior Art) Conventional document creation devices are configured such that various initialization processes are all executed at once in order to operate the device accurately when the power is turned on.

(Problem to be solved by the invention) However, as programs stored in ROM and RAM areas have become larger in recent years, the time required for each initialization process such as ROM checksum and RAM clearing has become longer. The time it takes for the nail to rise has become longer. For this reason, the operator may feel anxious that the device may be out of order, or may feel irritated if he or she wants to start an operation as soon as possible.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to shorten the time from power-on to startup of the actual machine by dividing and executing initialization processing.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a main initialization processing execution means that executes at least the minimum necessary initialization processing when the power is turned on, among all the initialization processing. and one or more sub-initialization processing execution means for executing the initialization processing required depending on the function selected after the power is turned on, when that function is selected.

(Function) When the power is turned on, the present invention executes the minimum necessary initialization processing, and the remaining initialization processing
Execute as necessary.

(Effects of the Invention) As described above, the present invention can shorten the startup time when the power is turned on by dividing and executing the initialization process. As a result, the present invention can provide a document creation device that can immediately start operation without causing anxiety or irritation to the operator.

(Example) Hereinafter, an example of the document creation device according to the present invention will be described.
This will be explained with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a control system of the present additional document creation device. CPU1 has ROM(A)2 and R
OM (8) Execute the program in 3 to perform various controls. In addition, CPU 1 has RAM (A>4 and RAM (
8) Access and operate 5 as necessary. Keystrokes from the keyboard 9 are input to the CPU 1 from the boat latch 6 via the data bus. Various step motors 8 constituting the printing device (not shown) receive control data sent from CPtJl via the address bus and data bus from baud 1 to latch 6, and each driver 7 receives the control data from CPLJl.
It is driven according to the command of l.

Next, the initialization process will be explained based on the flowchart of FIG. 2.

The routine shown in the figure starts when the power is turned on. First, in step 11 (hereinafter simply referred to as S11; the same applies to other steps), initialization processing is executed for input/output relationships (ilo) such as input/output ports. Next 8
Clear the RAM (A) at 12, and then clear the ROM at 813.
(A) Perform thumb check in step 2. These 811-81
The initialization process No. 3 is the minimum necessary process when the power is turned on.

For example, if a document production device has two operating modes, a word processor mode and a typewriter mode, one of the modes is automatically specified when the power is turned on;
After that, the operator switches the mode.

Therefore, when the power is turned on, only the initialization processing necessary for a predetermined mode is executed first, and the initialization processing necessary for other modes is executed immediately after switching to that mode.

814 determines whether the thumb check of ROM (A) 2 executed in 313 is correct or not, and if it is not correct, 814
15 error processing (error message display, etc.) is performed, and if the error is correct, the process moves to the next step 816.

816 is a key input standby process, and if there is key input power, the process advances to the next step 817. In 817, the content of key human power is R
It is determined whether or not it is necessary to start the OM (B) 3, and if the determination result is YES, the process moves to 818 to initialize the ROM (B) 3. Here, if the operation mode is not switched, the determination result at 817 is NO, and the process moves to the next step 819, where it is determined whether it is necessary to use the RAM (B)5. If RAM (B) 5 is to be used, the process moves to initialization processing of RAM (B) 5 at step 820 . If it is not necessary to use RAM (B) 5, each process (various til control of the document creation device) is performed in S21.
Execute. After that, return to 816 and wait for key personnel.

On the other hand, when the operation mode is switched manually using the keys, it is necessary to start up the ROM (B) 3 and use the RAM (8) 5, so first, in step 818, the ROM (B) is initialized. ROM (B) FLG in S31
After determining whether the ROM (B) is ON or not, a thumb check of the ROM (B) is performed at 832. Then, in step 833, it is determined whether the check result is correct or not, and if there is an error, the process moves to error processing in step 815. If the num check is correct, R at 834
OM (B) Proceed to FLG to 821 with ONL. Note that this ROM (B) FLG is a flag indicating that the initialization process of ROM (B) has already been executed.
When 818 starts again, 831 becomes NO, prohibiting re-execution of the initialization process.

When initialization processing of RAM (B) is requested, the routine at 820 first initializes RAM (B) at 841.
Determine whether it is FLG/fiON or not, and if the determination result is No.
If so, clear RAM (B) at 342. Then, in 843, the RAM (B) FLG is transferred to 821 in ONL. Note that this RAM ([3) FLG is RAM (B
) is a flag indicating that the initialization process has already been executed, and when +l■U S 20 starts, 841 is N.

Therefore, re-execution of the initial 1-serialization process is prohibited.

In this way, in this embodiment, the initialization processing is divided into two groups, and when the operation mode is switched, the initialization processing necessary for that mode is executed, thereby reducing the initialization processing at power-on and reducing the startup time. can be shortened.

Note that the number of divisions in the initialization process is the same as 2 in the above embodiment.
Needless to say, it is not limited to the number of divisions, and may be divided into three or more.
