Centralized control of each part of the electronic device 1. That is, the CPU 2 executes various processes based on the read predetermined program, stores the processing results in the work area in the RAM 8 and causes the display unit 4 to display them.
[0023]
In the test mode setting process (see FIG. 3), the CPU 2 displays a list of a plurality of country names indicating the test modes on the display unit 4 when a test mode setting key is input by the user. Next, when one of the country names in the list is selected and selected by a dedicated pen and then a test mode execution key is input, the CPU 2 selects a function key corresponding to the selected test mode. Information is extracted from the test mode table 91 stored in the ROM 9, and the selected test mode is set based on the extracted function key information. After the test mode is set, the CPU 2 enters a key input waiting state and executes various processes according to the user's key input. Here, when the option key is input by the user, the name of each function key is displayed on the display unit 4. Here, among the function keys, the names of the function keys that can be normally used are normally displayed, and the names of the function keys that are prohibited from being used are displayed in reverse video. Thereafter, in a state where the selected test mode is set, the CPU 2 enters a key input waiting state and executes processing according to the user's function key input. When the function key is input by the user, the CPU 2 determines whether or not the function key is prohibited from use based on the test mode table 91. If the function key is normally usable, When the key is normally input and the function key is prohibited from being used, the function key input input by the user is invalidated.
[0024]
The display drive circuit 3 outputs input data input from the input device 7 and the like as display signals to the display unit 4 in addition to data related to various processes executed by the CPU 2 and the processing results. Display at the display position. The display unit 4 is composed of an LCD or the like, and displays various data in accordance with a display signal input from the display drive circuit 3.
[0025]
The tablet 5 is an input device that combines a coordinate indicating device such as an input pen and a plate-shaped device that senses the specified coordinate. The position detection circuit 6 can be used for an electromagnetic induction method, a magnetostriction method, a pressure sensitive method, and the like. The position coordinates designated by the dedicated pen are detected by the coordinate reading principle. The tablet 5 is integrated with the display unit 4 and can perform an input operation by directly selecting and selecting a test mode or the like displayed on the display unit 4 with a dedicated pen.
[0026]
The input unit 7 outputs to the CPU 2 a key press signal that is pressed on a keyboard that includes up / down / left / right movement keys, numeric input keys, function keys, test mode setting keys, test mode execution keys, option keys, and various function keys. To do.
[0027]
A RAM (Random Access Memory) 8 has a program storage area for storing programs executed by the CPU 2 and various application programs, and a work area for temporarily storing input instructions, input data, processing results, and the like.
[0028]
A ROM (Read Only Memory) 9 stores a basic program corresponding to the electronic device 1. That is, a basic program that does not need to be rewritten, such as an initial display menu program, various function calculation programs, a test mode table 91 to be described later, and a test mode setting processing program to be described later, which is executed when the power of the electronic device 1 is turned on Storing.
[0029]
FIG. 2 is a diagram for explaining the configuration of the test mode table 91 in detail. 2, the test mode table 91 includes test mode items such as “NORMAL”, “JAPAN”, “USA”,..., “LIST” (statistic data list display function), “MAT”. ”(Matrix function),“ CPLX ”(complex number function),... That is, the function key information indicating the setting state of the function key that can be used for each test mode and the function key that is prohibited from being used is associated. “1” is stored in the function key that is prohibited from use, and “0” is stored in the function key that can be used.
[0030]
For example, since “0” is stored in all function operation function items corresponding to EXAM MODE “NORMAL”, when the EXAM MODE “NORMAL” is selected and executed by the user, all function keys are stored. Can be used. Also, looking at each function key item corresponding to EXAM MODE “JAPAN”, “1” is stored in the item “CPLX”, and “0” is stored in the other function key items. When the EXAM MODE “JAPAN” is selected and executed by the user, only the function key “CPLX” is prohibited.
[0031]
Thus, by selecting the country name shown in the item of EXAM MODE, the function of the electronic device 1 can be restricted according to the test of the country.

Next, the operation will be described.
FIG. 3 is a flowchart illustrating the test mode setting process of electronic device 1 according to the present embodiment.
[0034]
In FIG. 3, first, the CPU 2 starts a test mode setting process. When the user inputs a test mode setting key of the input unit 7 (step S1), a list of a plurality of country names indicating the test modes is displayed on the display unit 4. It is displayed (see FIG. 4A) (step S2). Here, the name of each country is stored in the EXAM MODE item of the test mode table 91 (FIG. 2). Next, the CPU 2 designates and selects one of the test modes (country names) displayed in a list on the display unit 4 with a dedicated pen (step S3), and further inputs a test mode execution key. Then (step S4), a set display “EXAM MODE SET!” Indicating that the selected test mode is set is displayed on the display unit 4. After several seconds, “U.S.A. “EXAM MODE” and the test mode set constantly are displayed (step S5).
Then, the CPU 2 searches and extracts function key information corresponding to the selected test mode from the test mode table 91 stored in the ROM 9, and selects the test mode selected based on the extracted function key information. Is set (step S6). That is, based on the function key information set for each test mode in the test mode table 91, function keys that can be used in the test mode and function keys that are prohibited from being used are set. Here, the setting of the test mode selected and instructed is completed, and a key input waiting state is entered. Thereafter, in the test mode, the CPU 2 executes various processes in accordance with the user's key input. In this flowchart, the contents related to the process corresponding to the option key input and the function calculation process corresponding to the various function key inputs. I will explain.
[0035]
After the test mode selected in step S6 is set, the CPU 2 determines whether or not the key input by the user is the option key (step S7). If it is not the option key (step S7; NO) If the key is an option key (step S7; YES), the name of each function key included in the function key information extracted in step S6 is displayed on the display unit 4 (step S8). Here, among the function keys, the name of the function key storing “0” is normally displayed in the function display area 4a, and the name of the function key storing “1” is displayed in reverse video.

[0037]
In the state in which the selected test mode is set, the CPU 2 determines whether or not the function key of the input unit 7 is input by the user (step S9), and if not input (step S9; NO). When the process proceeds to another process and is input (step S9; YES), it is determined based on the test mode table 91 whether the function key is prohibited from being used (step S10). If the function key is not prohibited (step S10; NO), the CPU 2 normally inputs the function key (step S11), and normally displays a display screen corresponding to the function key on the display unit 4 (step S11). S12). If the function key is disabled (step S10; YES), the CPU 2 invalidates the function key input by the user (step S13) and holds the display screen before the function key is input. Is displayed (step S14).
[0038]
Thereafter, the CPU 2 determines whether or not the function key is input again by the user (step S15). When the function key is input again (step S15; YES), the CPU 2 returns to step S9, and when the function key is not input (step S15; NO), the series of test mode setting processes ends.
[0039]
FIG. 4 is a diagram illustrating an example of a display screen of the display unit 4 in the above-described test mode setting process.
(A) shows a state where a plurality of country names indicating test modes are displayed, (b) shows a display indicating that the test mode is set, and (c) is set after the test mode is set. (D) shows a state in which function keys that can be used and function keys that are prohibited from being used are displayed in the selected test mode.
[0040]
As shown in FIG. 5A, when the test mode setting key is input by the user, a plurality of country names indicating the test modes are displayed in a list. Here, the country name designated and selected by the user with the dedicated pen is highlighted. In FIG. 5A, the country name “US A EXAM” is selected and highlighted.
[0041]
Thereafter, when the test mode execution key is input by the user, as shown in FIG. 4B, a set display indicating that the selected test mode is set, for example, “EXAM MODE SET” is displayed on the display unit 4. Is displayed. After several seconds, the display “USA EXAM MODE” indicating the selected test mode is constantly displayed at the top of the display ((c) in the figure).
[0042]
Further, when the option key is input by the user, the names of the usable function keys “LIST”, “MAT”, and “TABL” are normally displayed in the function display area 4a as shown in FIG. The names of function keys “CPLX”, “RECR”, and “EQUA” that are prohibited from being used are displayed in reverse video. Note that the names of the function keys displayed in the function display area 4a correspond to F1 to F6 of the input unit 7, as shown in FIG. In addition, during the function restriction, as shown in FIGS. 7C and 7D, the display indicating the selected test mode is displayed at the top of the display unit 4, in this case “US EXAM MODE” is displayed. Always displayed.
[0043]
As described above, according to the electronic device 1 of the present embodiment, in the test mode setting process, the CPU 2 displays the country name indicating the test mode on the plurality of display units 4 when the test mode setting key is input by the user. Display a list. Next, the CPU 2 selects and selects a test mode from among a plurality of test modes (country names) displayed in a list by using a dedicated pen and then inputs a test mode execution key. The function key information corresponding to is extracted from the test mode table 91 stored in the ROM 9, the test mode selected based on the extracted function key information is set, and the selected test mode is displayed. The process that always displays in the upper row is performed. Thereafter, when a function key is input by the user, the CPU 2 determines whether or not the function key is prohibited from use based on the test mode table 91. If the function key is normally usable, When the key is normally input and the function key is prohibited from being used, the function key input input by the user is invalidated.
[0044]
Therefore, by selecting an arbitrary function restriction mode from among the plurality of function restriction modes by the selection means, the use of the function corresponding to the selected function restriction mode can be prohibited, and the use of the function by one unit is possible. Since a plurality of prohibited states can be realized, for example, a single unit can cope with a test in each country, and a function calculation function can be unified for all examinees according to the test in each country. In addition, the function restriction status display means can easily display which country's test is available, so that the examiner can check whether the candidate is using an electronic device that supports the specified test during the test. Easy to confirm.

If the function key is input again (step S71; YES), the CPU 2 returns to step S65, and if the function key is not input (step S71; NO), has the test mode setting key been input again? It is determined whether or not (step S72). When the test mode setting key is not input, the CPU 2 executes processing such as a function calculation function corresponding to the input function key. When the test mode setting key is input, the CPU 2 sets the test mode setting capacitor. The charge is detected (step S73), and it is determined whether or not the detected charge amount exceeds a predetermined threshold value (step S74). If exceeded, the CPU 2 invalidates the test mode setting key input input by the user (step S76), and holds and displays the display screen before the test mode setting key is input (step S77). ), The process returns to step S65.
[0072]
If the detected charge amount does not exceed the predetermined threshold value in step S74 (step S74; NO), the CPU 2 clears the processing result stored in the work area of the RAM 8 (step S75), A series of time limit test mode setting processing ends.
[0073]
FIG. 9 is a diagram illustrating an example of a display screen of the display unit 4 in the above-described time limit test mode setting process.
(A) shows a display screen when the test mode execution key is input again after a certain period of time has not elapsed since the first test mode execution key input, and (b) after the first test mode execution key input, A display screen when the test mode execution key is input again after a predetermined time has elapsed is shown.
[0074]
After the first test mode execution key is input, the function screen corresponding to each function calculation function is displayed on the display screen of the display unit 4 of the electronic device 100 as shown in FIG. Function keys “CPLX”, “RECR”, and “EQUA” are highlighted. Here, even if the test mode execution key is input again by the user before the fixed time has elapsed, the test mode setting process is not executed, and the display screen is held as shown in FIG.
[0075]
Further, when the test mode execution key is input again by the user after a predetermined time has elapsed, the test mode setting process is immediately executed, and the selected test mode is set as shown in FIG. For example, “EXAM MODE SET” is displayed on the display unit 4. After that, based on the newly selected test mode, the input of function keys that are prohibited from use is invalidated.
[0076]
As described above, according to electronic device 100 in the present embodiment, in time limit test mode setting processing, CPU 2 firstly performs the same as steps S1 to S4 in the above-described test mode setting processing (see FIG. 3). When the test mode execution key is input, the test mode setting capacitor is turned on, and function key information corresponding to the test mode selected from the test mode table 91 is extracted and extracted. The test mode selected based on the function key information is set. After the test mode is set, the CPU 2 enters a key input waiting state and executes various processes according to the user's key input. Here, when the option key is input by the user, the name of the function key included in the function key information is displayed on the display unit 4. At that time, the function keys that are prohibited to use are displayed in reverse video (see FIG. 9A). Thereafter, in a state where the selected test mode is set, the CPU 2 enters a key input waiting state and executes processing according to the user's function key input. When the function key is input by the user, the CPU 2 determines whether or not the function key is prohibited from use based on the test mode table 91. If the function key is disabled, the CPU 2 inputs the function key. The function key input is invalidated, and the display screen before the function key is input is held and displayed. Thereafter, the CPU 2 again determines whether or not the test mode setting key is input again. When the test mode setting key is input, the CPU 2 detects the charge of the test mode setting capacitor, and the detected charge amount is predetermined. If the threshold is exceeded, the test mode setting key input again by the user is invalidated, and the display screen before the test mode setting key is input is held and displayed.
[0077]
Therefore, it is possible to invalidate the second test mode setting key input for a certain period of time after the first test mode setting key input, and to accept the test mode setting key input immediately after a certain period of time. After unifying the function calculation function that is prohibited for all test takers, the test taker executes the test mode setting process again during the test time, and the function calculation function for which use is prohibited is restored without permission. Can be prevented.
