Abstract

PURPOSE:To access a card, to refer load information, which are stored on the card, and to load a program file to a main body memory by recognizing that the memory card is mounted when a power source is turned on. CONSTITUTION:When the power source is turned on, a CPU 1 executes the initial set of each device based on a system program in a system ROM 10 and checks an operating state. Afterwards, operation is moved to program load processing from a memory card 9. At first, it is checked whether the memory card 9 is connected or not. When the memory card 9 is connected, it is decided whether the memory card 9 is correctly formatted under a memory managing system or not. When the memory card is correctly formatted, the contents of the file are read and concerning the designated file, the file on the memory card 9 is copied on a memory 7.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a portable terminal device that reads predetermined information from a removable memory card and executes data processing.

[Conventional technology]

Conventionally, on this type of portable terminal device (handy terminal device), an application program to be executed is stored in a memory backed up by a battery within the main body of the handy terminal, so that it can be read and executed at any time.

If this type of application program is destroyed for some reason, the same application program is loaded from the host computer via the communication port and the program repair process is executed.

Alternatively, you can store the above application program in a semiconductor memory card, and when the memory in the main body of the handy terminal device is destroyed, connect the memory card to the handy terminal device, load the above application program, and perform the program recovery process. was running.

[Problem to be solved by the invention]

In this way, with conventional handheld terminal devices, when reloading a specific application program, it must be done via a communication port or memory card, or the operator must instruct the application program to be loaded as a handheld terminal device. . However, since there are a wide variety of application programs on the host, and several types of programs and data are also written on memory cards, etc., it is not possible to read out the desired application unless complicated instructions are given. However, there were operational problems such as the maintenance of application programs requiring a considerable amount of time, which seriously hindered business execution.

This invention was made in order to solve the above problems, and is a portable device that can automatically load a desired program file into the main body memory while referring to the loading conditions of the program file stored in the connected memory card. The purpose is to obtain a terminal device.

[Means for Solving the Problems] A portable terminal device according to the present invention includes a detection means for detecting the attachment/detachment state of a memory card when the power is turned on, and a detection means for detecting the attachment/detachment state of a memory card. A load control means is provided for controlling the loading of a specific program file into the main body memory without referring to the load information.

[Function] In this invention, when the power is turned on, the detection means monitors whether or not a memory card is inserted, and when the detection means recognizes that a memory card is inserted, the memory card 1 is accessed and the memory card is stored. A rotor control means controls the loading of the program file instructed to be loaded into the main body memory by referring to the load information stored in the program file, and automatically loads the program file into the main body memory while identifying the necessary program file.

4 is a communication port for exchanging data with the host computer.

Reference numeral 5 denotes a power supply control circuit, which controls the predetermined power-on of each device connected via the system path 11 from the battery 6 serving as the main power supply. Reference numeral 7 denotes a main body memory that stores application programs and data. 8 is the interface,
It interfaces the reading process of the memory card 9 connected to the handy terminal.

A memory card 9 stores management information corresponding to program files and data files stored in a directory section. Note that the memory card 9 can store each program file together with management information, and check whether the contents of the file have been destroyed on a file-by-file basis.

Note that the CPU 1 also serves as a detection means, a load control means, etc., and when the power is turned on, the CPU 1 monitors whether or not the memory card 9 is installed, and when it detects that the memory card 9 is installed, the CPU 1 detects whether or not the memory card 9 is installed. , accesses the load information stored on the memory card 9, starts loading control of the program file instructed to be loaded into the main body memory 7 according to the procedure shown in FIG. 2, and identifies the necessary program file. while automatically reloading the main body memory 7.
to be rotated.

Next, the program file loading processing operation between the memory card 9 and the main body memory 7 according to the present invention will be described with reference to FIG.

FIG. 2 is a flowchart showing an example of a procedure for loading a program file into the main body memory 7 shown in FIG. Note that (1) to (6) indicate each step.

When the power is turned on, CPU 1 reads system ROM 10.
Each device (2 above) based on the system program during
4, 7, 8, etc.) and check the operating status, the process moves to the initial program loading process from the memory card 9, and first, it is determined whether the memory card 9 is connected to the handy terminal. (1), if No, the initial program loading process is immediately ended and moves on to other processes; if YES, the connected memory card 9
It is determined whether it is correctly formatted under the memory management method (2), and if No, it moves to other processing,
If YES, it is determined whether a file containing load information (the file name will be described later) exists (3). If NO, proceed to other processing; if YES, read the contents of the file, and if the specified file already exists in the main body memory 7 on the handy terminal, delete the file (
4) Copy the file on the memory card 9 to the main body memory 7 (5). Next, it is determined whether all the specified files have been loaded into the main body memory 7 (6), and if no, the process returns to step (4), and if YES, other processing based on the application program is started.

FIG. 3 is a schematic diagram showing an example of a load information file resident in the memory card 9 shown in FIG. 1, and 21 is a directory section that stores file management information of the load information file 22.

Reference numeral 23 denotes a free area, which is set as necessary in preparation for expansion of the application.

31 is a memory clear command, for example r. The case of ACJ is shown, and this memory clear instruction 31 and termination instruction 36, for example r. Program file 32 sandwiched between ENDJ.
33 and data files 34 and 35 become initial load files, and if the load information file 22 exists, loading is started. This allows you to instruct replacement of only a part of the program in the main body or all of it.

Note that the file name and file format are set in each system, and are not limited to this embodiment.

As can be seen from this figure, when the CPU i receives a memory clear instruction 31 when accessing the memory card 9, it erases the corresponding area of the main body memory 7 and clears the program file 32.
．． In preparation for initial loading processing of program file 33 and data file 34.35, the initial loading processing of program file 32.33 and data file 34.35 is executed when the I/O timing is established, and the program is stored in the corresponding area of main body memory 7. File 32.33 and data file 34
．． 35 is made resident, and thereafter the main body memory 7 is accessed to execute data processing.

In the above embodiment, the program files 32, 33 and data files 34.
Although we have explained the case where the initial load process of 35 is executed, if a keyword or password, etc. in a preset specific area of the main body memory 7 is stored, all files on the main body memory 7 are unconditionally loaded. Even if the configuration is such that all files on the memory card 9 are loaded after erasing the files, this does not hinder the application of the present invention, and the same effects as described above can be expected.

〔Effect of the invention〕

As explained above, the present invention includes a detection means for detecting the insertion/removal state of a memory card when the power is turned on, and a detection means for detecting the installation/removal state of a memory card, and a specific program while referring to the load information stored on the memory card when the detection means detects the attachment/removal state of the memory card. A load control means is provided to control the loading of files into the main unit's memory, so if data or programs in the main unit's memory are destroyed for some reason, you can simply prepare a memory card for initial program loading in advance. Anyone can repair a particular corrupted program or particular data by a simple operation, ie, by inserting a memory card. Therefore, program and data restoration work can be completed in any working area in a short time. Furthermore, even if a program needs to be updated, a specialized operator can simply change the memory card without having to rewrite and repair all memory cards, which greatly reduces the cost of changing programs. It has excellent effects such as:
