Abstract

PURPOSE:To reduce the cost of system maintenance by using data stored in an external storage device to correct/update a processing procedure or an optional part. CONSTITUTION:The electronic apparatus consists of processing procedures 1 stored in the inside of a body 2, a processing procedure loading means 3 for loading a processing procedure concerned to the body 2 and a processing procedure correcting/updating means 5 for checking the existence of the corrected/updated data 4 stored in the external storage device by using the loaded processing procedure as a trigger, and at the time of existence of the data, correcting/updating the processing procedure concerned or an optional part. Even if a trouble is generated in the processing procedure stored in the inside, the correcting data stored in the external storage device can be used and the system of the electronic apparatus whose cost can be reduced is constituted without changing the preceding system.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention uses the loading of the relevant process/procedure as a trigger to use modified/updated data if it exists in an external storage device (for example, PROM). The present invention relates to an electronic device that is characterized by the ability to perform correction/update processing on corresponding processing/procedures or arbitrary parts.

[Prior art] Most conventional electronic devices load the processes/procedures built into the main unit and transfer the control as is.
There were few systems that could use the data stored in OM to modify or update the corresponding process/procedure or any part.

[Problems to be solved by the invention] However, in the above conventional example, if the processing/procedures built into the main unit are loaded and the control is directly controlled, even if there are some errors or defects, it cannot be dealt with and the internal It was necessary to revise the processes and procedures and recreate them, which resulted in huge costs.

Furthermore, it has been impossible to easily upgrade the internal processes and procedures.

・If data stored in an external storage device (e.g. PROM) cannot be modified or updated for the relevant process/procedure or any part, all applicable processes/procedures will be canceled even if there is a partial error or defect. It was necessary to store it in an external storage device, and it was necessary to have it redundantly with internal storage processing and procedures.

There were some drawbacks.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and includes the following configuration as a means for achieving this purpose.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the overall configuration of the processing apparatus of the present invention.

That is, the present invention includes an internally stored process/procedure 1, a process/procedure loading means 3 for loading the corresponding process/procedure into the main body (RAM) 2, and an external storage using the loaded process/procedure as a trigger. A process/procedure correction/procedure check to see if there is correction/update data 4 stored in a device (for example, PROM), and if so, use that data to correct/update the corresponding process/procedure or any part. It consists of updating means 5.

FIG. 2 shows an embodiment of the electronic device of the present invention.

That is, FIG. 2 shows an embodiment of the correction/update means, in which the corresponding processing/procedures are stored in a rotary SL external storage device (for example, pRO).
Check whether there is correction/update data for the process/procedure loaded in M) S2, and if it exists, use that data for the corresponding process/procedure or any part to perform correction/update S3゜As shown above. Process loading means that loads the processes/procedures built into the main unit, the loaded corresponding processes/procedures, etc.
It has a process update control means that performs correction and update processing using a procedure as a trigger. A system is built that allows parts to be corrected and updated.

Additionally, the following may be mentioned as other external storage devices.

1 FD (Flexible Disk) 2 HD (Hard Disk) 3 MFD (Micro FD) 4 IC Card [Effects of the Invention] As explained above, the present invention utilizes data stored in an external storage device (for example, PROM), It is now possible to modify or update processes/procedures or any part, and even if a problem occurs in the internally stored processes/procedures, the correction data stored in the external storage device can be used. This makes it possible to construct an electronic device system that can reduce costs without changing the previous system.

Claims (1)

[Scope of Claims] Processing loading means that includes a removable external storage device and loads processing/procedures built into the main body, and processing modification/updating processing that uses the loaded corresponding processing/procedure as a trigger to perform correction or update processing. It has an update control means, checks whether correction/update data for the corresponding process/procedure is stored in an external storage device (for example, PROM), and if it exists, uses that data to update the corresponding process/procedure or any part. An electronic device that is characterized by its ability to be modified and updated.
