FIG. 14 shows a fourth embodiment of the present invention (No. 1).
9 is a flowchart showing a time specification function restriction process of the electronic computing device according to FIG.

FIG. 15 is a diagram showing an input display screen of a restriction function and a time limit associated with the time specification function restriction processing of the electronic computer.

When the function restriction setting key 34 provided on the upper front of the apparatus main body 11 is operated, a control program for the time designation function restriction mode is started, and the restriction mode memory 23b in the RAM 23 is set to the restriction mode memory 23b. The flag is set (step S1).

Then, the display screen of the liquid crystal display unit 13 enters a time designation function restriction mode display state for displaying an arbitrary function to be restricted and the time limit thereof (step S).
2).

When a function key corresponding to an arbitrary function to be restricted is selected and operated by the key input section 12 and confirmed by the "EXE" key, the selected and restricted arbitrary function to be restricted is performed. As shown in FIG. 15, the type of the function is displayed on the display screen of the liquid crystal display unit 13, and the function waits for input of a time limit for the function to be restricted (step S).
3, S4 → S5).

Here, when an arbitrary time limit for the function to be limited is input and specified in the key input section 12 and the "EXE" key is operated, the input and specified time limit is displayed on the liquid crystal display. In addition to being displayed on the display screen of the unit 13 together with the restricted function function, data indicating the type of the restricted function function and data of the restricted time are stored in the restricted function memory 23c and the restricted time memory 23d in the RAM 23, respectively. It is stored (step S6).

Then, the timer memory 23 in the RAM 23
At f, charging / discharging of timed data which is sequentially updated and stored or a capacitor (not shown) is started, and measurement of the function limit time stored in the time limit memory 23d is started (step S7).

For example, in the time specification function restriction mode display screen shown in FIG.
On (integration calculation function) and “Eqation (equation calculation function)” are selected and confirmed, and the function limit time is specified as “90 min”, so that the integration and equation calculation functions will be performed for the next 90 minutes. Is restricted and set to an unusable state.

When a key input corresponding to any function function is performed in such a time designation function restriction state, it is determined whether or not the function function is under function restriction, that is, in this case, an integral calculation function is performed. It is determined whether the function is an equation calculation function (steps S8 and S9).

Here, when it is determined that an execution input of a function function other than the function to be restricted has been made, a control program corresponding to the executed function function is started, and a normal process desired by the user is performed. (Step S9 → S
10).

On the other hand, when it is determined that the type of the function entered by the key input is the function to be restricted, which is set and stored in the restriction function memory 23c in the RAM 23, the time data or the time data in the timer memory 23f is determined. It is determined whether or not the function limit time stored in the time limit memory 23d has elapsed according to the discharge state of the charge stored in the capacitor (steps S8, S9 → S1).
1).

If it is determined that the time limit has been reached, the key input of the function function is ignored, and message data indicating that the corresponding function is being limited is read from the limit message memory 23g. Is displayed on the liquid crystal display unit 13 (steps S11 → S12, S13).

Thereafter, similarly to the above, when a key input corresponding to the restriction target function set and stored in the restriction function memory 23c in the RAM 23 is performed, the function restriction stored in the restriction time memory 23d is performed. If it is determined that the time has elapsed, the respective stored data in the limited function memory 23c and the limited time memory 23d are erased, and the limited mode flag set in the limited mode memory 23b is reset. The setting state of the function restriction is released (steps S8, S9 → S11 → S14).

Then, a control program corresponding to the input function is started, and normal processing desired by the user is performed (step S15).

Therefore, according to the time specification function restriction process of the electronic computer according to the fourth embodiment (No. 1) of the above configuration, an arbitrary function function is selectively set and stored as a restriction target function by a key input operation. At the same time, when the time limit is specified and input, during the specified function time limit, the key input for executing the function function specified as the restriction target is ignored, and the function function is being limited. Is displayed on the liquid crystal display unit 13. For example, when the electronic computer is brought to the test site, a calculation function that is not permitted to be used in accordance with the content of the test or the rules of the subject may be changed during the test time. It is now possible to easily limit the function by responding to it, and to notify the outside by displaying a restriction message indicating that the function is being restricted. .

In the fourth embodiment (part 1),
For example, it is necessary for each test taker in the test hall to individually perform the selection input of the function to be restricted and the specification input of the time limit for his / her own electronic computing device in the same manner as in the following fourth embodiment ( Part 2) As described in (see FIGS. 16 and 17), a certain electronic computer generates a function restriction password in which the restriction target function, the restriction time, and the restriction start time are encoded. Other people's electronic computing devices may be configured to set the same function restriction mode by inputting this function restriction password.

FIG. 16 shows a fourth embodiment of the present invention (part 2).
4 is a flowchart showing a function restriction password generation process and a function restriction setting process using a password of the electronic computing device according to the embodiment.

FIG. 17 is a view showing a password generation display screen and a restriction function setting screen which are displayed along with the function restriction password generation processing and the function restriction setting processing by the password of the electronic computer.

In one of the electronic calculators, FIG.
As in the processing of steps S1 to S6 in FIG.
As shown in (A1), the function function to be restricted is arbitrarily selected and input, and the restricted function memory 23c in the RAM 23 is input.
When the time limit is specified and input and stored in the time limit memory 23d, and set to an arbitrary function limit state (steps A1 to A6), the time limit is stored in the limit function memory 23c. A function-restricted password is generated by an encoding process according to a predetermined algorithm using the number of the target function function, the function-limited time stored in the time-limited memory 23d and the limited execution input time as the current time as variables. Then, it is stored in the restricted password memory 23h and displayed on the liquid crystal display unit 13 as shown in FIG. 17 (A2) (steps A7, A
8).

Then, the electronic computing device that has generated the function-restricted password, according to the limited functions and the limited time stored in the limited-function memory 23c and the limited-time memory 23d in the RAM 13, respectively, starts from step S8 in FIG. The processing shifts to the time specification function restriction processing.

Then, in other electronic computing devices,
By operating the function restriction setting key 34, the control program in the time designation function restriction mode is started, and in the state where the restriction mode flag is set in the restriction mode memory 23b in the RAM 23, the password input mode is performed by a predetermined key operation. 17 and the function-restricted password generated and displayed on the one electronic computing device, as shown in FIG.
As shown in (B1), when a key is input and displayed, the function-restricted password is analyzed, and as shown in FIG. The input (start) time is acquired and displayed,
The data is set and stored in the limited function memory 23c and the limited time memory 23d in the RAM 23 of the electronic computer (steps B1 to B4).

Then, the time limit from the current time is calculated in accordance with the analyzed function-acquired function limit time and the limit execution input (start) time, and the process proceeds to step S7 in FIG.
The process proceeds to the subsequent time specification function restriction process (step B).
5).

As a result, the other electronic computing devices are set to the same time-specified function restricted state as the one electronic computing device.

Therefore, according to the function restriction password generation processing and the function restriction setting processing based on the password according to the fourth embodiment (No. 2) of the above-described configuration, any one of the electronic computers can be restricted. When the function function is selected and set, and the time limit is designated and input, a function restriction password that encodes the function to be restricted and the time limit is generated, and then the function function and the time limit are arbitrarily selected. According to the function restriction state,
In other electronic computing devices, when the generated function-restricted password is input, the password is analyzed and the same restricted target function and the time limit as set in the one electronic computing device are obtained, Since the function is restricted according to this, for example, a function-restriction password corresponding to the contents of the test is generated by an electronic computer provided by the test manager, and this is notified to the examinee, and the personal computer of each individual examinee is generated. And setting the function to the restricted function state, it is possible to easily set the electronic computing devices of all test takers to the desired time-specified function restricted state.

In the fourth embodiment (part 1) and (part 2), even if a limited time is designated and input for an arbitrarily selected limiting function and a plurality of limiting functions are selected, the same applies. Although the function limit time is set to be the same, as described in the following fourth embodiment (part 3) (see FIGS. 18 and 19), each of a plurality of arbitrarily selected functions to be limited is set. It is good also as a structure which sets a different function time limit with respect to.

FIG. 18 shows a fourth embodiment (part 3) of the present invention.
9 is a flowchart illustrating a time-specific function-based restriction process of the electronic computing device according to the first embodiment.

FIG. 19 is a view showing an input display screen of a limit function and a time limit associated with the time limit function-specific limit processing of the electronic computer.

When the function restriction setting key 34 provided on the apparatus main body 11 is operated, the control program for the time-specific function-specific restriction mode is started, and the restriction mode flag is stored in the restriction mode memory 23b in the RAM 23. It is set (step C1).

Then, the display screen of the liquid crystal display unit 13 enters a time-specific function-specific restriction mode display state for displaying an arbitrary function to be restricted and its time limit in association with each other (step C2).

Then, a function key corresponding to an arbitrary function to be restricted is selected and operated in the key input section 12, and the time limit is designated and input for each selection of the restricted function. When the confirmation operation is performed by the key, as shown in FIG. 19, the types of the plurality of function functions to be selected and confirmed are associated with the time limits individually designated and input for each of the function functions. Is displayed on the display screen of the liquid crystal display unit 13 (steps C3, C4, C5).

Then, the data indicating the types of the plurality of restricted function functions and the data of the limited time in each of them are stored in the limited function memory 23c in the RAM 23, respectively.
And stored in association with the time limit memory 23d (step C6).

Then, the timer memory 23 in the RAM 23
The measurement of the function limit time of each of the plurality of limit functions stored in the time limit memory 23d is started based on the timekeeping data sequentially updated and stored in step f (step C).
7).

For example, in the restriction mode display screen for each time designation function shown in FIG.
ion (integration calculation function), "Eqation (equation calculation function)" and "Mat (matrix calculation function)" are selected and set, and their respective function limit times are set to "135 m".
In "," 90 min ", and" 45 min "are individually specified, thereby setting the matrix calculation function to be restricted and unusable for the next 45 minutes,
For the next 90 minutes, the equation calculation function is restricted and set to an unusable state, and for the next 135 minutes, the component calculation function is set to a disabled state.

In such a time-limited function-specific restriction state, if a key input corresponding to any function function is performed, it is determined whether or not the function function is being restricted, that is, in this case, a matrix calculation is performed. It is determined whether the function is a function, an equation calculation function, or an integral calculation function (step C8,
C9).

Here, when it is determined that an execution input of a function function other than the function to be restricted has been made, a control program corresponding to the execution-input function function is started, and normal processing desired by the user is performed. (Step C9 → C
10).

At this time, it is determined whether or not the respective function-limited time has passed for all the limited functions stored in the function-limited memory 23c and the time-limited memory 23d, that is, the function-limited state is completely released. If it is determined that the restriction has not been released even for one restriction target setting function, the process enters the function function input waiting state in step C8 (step C11 → C).
8).

On the other hand, if it is determined that the type of the function entered by the key input is one of a plurality of functions to be restricted set and stored in the restricted function memory 23c in the RAM 23, the timer memory In accordance with the time measurement data at 23f, it is determined whether or not the time limit of the key-inputted limit target function stored in the time limit memory 23d has elapsed (steps C8, C9 → S12).

Here, if it is determined that the key-input function function to be restricted is within the time limit, the key input of the function function is ignored and the corresponding function is restricted. The indicated message data is read from the restriction message memory 23g and displayed on the liquid crystal display unit 13 (steps C12 → C13, C14).

Thereafter, similarly to the above, when a key input corresponding to the restriction target function set and stored in the restriction function memory 23c in the RAM 23 is performed, the key is input to the restriction time memory 23d corresponding to the restriction function. When it is determined that the stored function time limit has elapsed, the data of the limited function and the time limit stored in the limited function memory 23c and the time limit memory 23d are deleted, and the input The control program corresponding to the performed function is started, and normal processing desired by the user is performed (steps C8, C9 → C12 → C15, C10).

That is, four times from the point of execution of the function restriction
When a key input for entering the matrix calculation mode is performed after 5 minutes have elapsed, the restriction data relating to the matrix calculation function is deleted, and a key input for entering the equation calculation mode after 90 minutes has elapsed from the same point. When this is performed, the restriction data relating to the equation calculation function is deleted, and when a key input for switching to the integration calculation mode is performed after 135 minutes have elapsed from the same point, the restriction data relating to the integration calculation function is deleted. This allows
When the restriction mode flag set in the restriction mode memory 23b is reset and it is determined that the function restriction state has been completely released, the series of time-specified function restriction processing is terminated, and all the mounted functions are used. The state returns to a possible normal use state (step C11 → end).

Therefore, according to the restriction processing for each time designation function of the electronic computer according to the fourth embodiment (No. 3) of the above configuration, a plurality of arbitrary function functions can be selectively set as restriction target functions by key input operation. When the setting is stored and an individual time limit is designated and input for each of the limited functions, during the designated function limited time, the key input for executing the corresponding restricted target function is ignored, A message indicating that the function function is being restricted is displayed on the liquid crystal display unit 13. Then, each time the time limit of each of the plurality of specified restricted function functions elapses, the restricted state of the corresponding function function is released.For example, when this electronic computing device is brought to the test site, Multiple calculation functions that are not allowed to be used according to the content of the test for each subject can be easily restricted according to each test time range, and a restriction message is displayed to indicate that the function is being restricted. Be able to inform outside.

In the fourth embodiment (No. 1), (No. 2) and (No. 3), when an input operation for executing a function function set as an object to be restricted and during a time limit is performed, the function function Is configured to display a message indicating that is being restricted. However, as described in the following fourth embodiment (part 4) (see FIGS. 20 and 21),
When the menu of installed functions (modes) is displayed as a list of icons, the icon indicating the restricted function is changed and displayed,
When the icon of the restriction target function is selected and input, the remaining remaining time may be displayed at another irrelevant icon position to notify that the input function is being restricted.

FIG. 20 shows a fourth embodiment of the present invention (part 4).
9 is a flowchart showing a time-specific function-based restriction display process of the electronic computing device according to the first embodiment.

FIG. 21 is a view showing an input display screen of a limit function and a limit time displayed in association with the time limit function-specific limit display processing of the electronic computing device, and a menu screen for selecting a mounted function.

When the function restriction setting key 34 provided on the apparatus main body 11 is operated, the control program for the time-specific function-specific restriction mode is started, and the restriction mode flag is stored in the restriction mode memory 23b in the RAM 23. It is set (step D1).

Then, the display screen of the liquid crystal display unit 13 enters a time-specific function-specific restriction mode display state for displaying an arbitrary function to be restricted and the time limit thereof in association with each other (step D2).

Then, a function key corresponding to an arbitrary function to be restricted is selected and operated in the key input section 12, and the time limit is designated and input for each selection operation of each restricted function. When the keys are sequentially operated by the keys, as shown in FIG. 21A, the types of the plurality of function functions to be selected and limited are individually designated and input for each of the function functions for the time limit. Is displayed on the display screen of the liquid crystal display unit 13 and the limited function memory 23 in the RAM 23.
c and the time limit memory 23d (step D).
3-D6).

Then, the timer memory 23 in the RAM 23
The measurement of the function limit time of each of the plurality of limit functions stored in the time limit memory 23d is started based on the timekeeping data sequentially updated and stored at f.
As shown in FIG. 21B, a menu screen for selecting a mounted function is displayed on the liquid crystal display unit 13 as a list screen of icons indicating each function, and the function is being limited based on the limited function memory 23c and the limited time memory 23d. For example, the icon I3 indicating the matrix calculation function and the icon IA indicating the equation calculation function are displayed in an inverted white outline and changed and displayed (steps D7 and D8).

In the menu screen display in the restricted state according to the time designation function, some function function (mode)
Is selected and input, the icon indicating the selected function (mode) is changed and displayed, and it is determined whether or not the selected function is a restricted function (step D9). , D10, D11).

Here, if it is determined that an icon indicating a function function (mode) other than the function to be restricted is selected and input, a control program corresponding to the selected and input function function (mode) is started, and the user is activated. A desired normal process is performed (steps D11 → D12).

On the other hand, when it is determined that the type of the function corresponding to the selected and inputted icon is one of the plurality of functions to be restricted set and stored in the restricted function memory 23c in the RAM 23. For example, the MAT icon I of the matrix calculation function in the function restricted state shown in FIG.
If it is determined that 3 has been selected and input,
As shown in (C), the MAT icon I3 is displayed as a mask I3 'to indicate that the selected function is being restricted, and an icon irrelevant to the selected function or the function being restricted, for example, a PRGM icon IB Is temporarily erased, and the remaining time limit TL calculated based on the time measurement data read from the timer memory 23f and the time limit of the selection function (MAT) read from the time limit memory 23d is replaced with, for example, "25 mLATE". (Steps D9 to D11 → D13, D1
4).

Further, if the entry input to the matrix calculation function with the mask display I 3 being restricted in function is determined based on the detection of the key operation input instead of the icon selection, the key input of the selected function is performed. Is ignored, and message data indicating that the corresponding function is being restricted is read from the restricted message memory 23g and displayed on the liquid crystal display unit 13 (steps D15 → D16, D1).
7).

On the other hand, there is no entry for the matrix calculation function whose function is being displayed with the mask display I 3 being restricted, and “OF
When the "F" key is operated, as shown in FIG. 21 (B), the icons I3 and I3 of the function functions whose functions are being restricted.
The screen returns to the display state of the menu screen in which A is displayed in reverse white outline, and waits for selection of an icon of an arbitrary function (steps D15 → D18 → D9).

Thereafter, when the time limits respectively corresponding to the plurality of functions to be limited stored in the time limit memory 23d in the RAM 23 have elapsed, all the function restrictions are released, and an arbitrary selection icon is displayed. The corresponding function is normally started and executed.

Therefore, according to the restriction display processing for each time designation function of the electronic computer according to the fourth embodiment (No. 4) of the above configuration, any of a plurality of function functions can be selectively selected by the key input operation. And memorize it as
When an individual time limit is designated and input for each of the limited functions, the icons I3 and I3 in the function limited state are displayed on a menu screen including a list of mounted function icons.
IA is displayed in reverse video, and when an icon of a function during this function restriction is selected and input, the remaining time limit TL of the selected and input restricted function is displayed at another icon position irrelevant to the restricted function. Then, the key input for executing the restriction function is ignored, and a message indicating that the function function is being restricted is displayed on the liquid crystal display unit 13. Not only can you easily limit the number of calculation functions that are not allowed to be used according to the content of the exam for each subject, etc.
You can now display the remaining time of the function that is being restricted.

In the fourth embodiment (part 1) to (part 4), the restriction target can be selectively set for each function (mode) mounted on the apparatus main body 11, but the following configuration is adopted. As described in the fourth embodiment (part 5) (see FIGS. 22 and 23), the configuration may be such that the use of each command in the program calculation function can be selectively restricted.

FIG. 22 shows a fourth embodiment (part 5) of the present invention.
9 is a flowchart showing a program function restriction process and a program mode process of the electronic computing device according to the first embodiment.

FIG. 23 is a view showing an input display screen of a restriction command accompanying the program function restriction processing and the program mode processing of the electronic computer and a display state of execution of creation and execution of the program.

When a function restriction setting key 34 provided on the apparatus main body 11 is operated, a control program for the function restriction mode is started, and the restriction mode memory 2 in the RAM 23 is activated.
The restriction mode flag is set for 3b (step E1).

When a program calculation function is specified by key input as a function to be restricted, the function of the program calculation function itself is restricted, or the use of each command of a program used in the program calculation function is restricted. It is determined according to the designation by the key operation (steps E2 and E3).

Here, if it is determined that the use restriction for each command is not specified, the process shifts to the time specification restriction processing only for the program calculation function (step E3 → E).
7).

On the other hand, if it is determined that the use restriction for each command has been specified after the specification of the program calculation function, as shown in FIG. 23A, a list of commands used in creating the program is displayed. A display screen is displayed on the liquid crystal display unit 13 (steps E3 → E4).

When a command whose use is to be restricted (impossible) is selectively designated in the display state of the command list display screen, the restricted designated program command is stored in the restricted command in the RAM 23. Memory 23
e is stored, and an execution input state of the function restriction based on this is entered (steps E5 and E6).

As described above, when the program calculation mode is started with any command used for the program calculation function being selectively designated as a restriction target, FIG.
As shown in (B), an arbitrary program creation display screen is displayed on the liquid crystal display screen, and an arbitrary program is created and displayed according to an arbitrary key operation (step F1).

When the "EXE" key is operated to instruct the execution of the program after the arbitrary program is created, the RAM is included in the execution program.
It is determined whether or not there is a restriction target command stored in the restriction command memory 23e in step 23 (steps F2 and F3).

If it is determined that there is no command to be restricted in the execution program, a normal program calculation process according to the execution program is performed (steps F3 → F4).

On the other hand, during the execution program, the RAM
If it is determined that there is a restricted command stored in the restricted command memory 23e in the program 23, the execution of the program is stopped and, as shown in FIG. A use restriction command message 22a 'indicating that the use of the command is restricted is displayed in correspondence with the program part of the restricted command (steps F3 → F).
5, F6).

Then, the program including the restricted command is displayed on the program input creation screen (FIG. 23).
(Refer to (B)), and the display form of the command to be restricted is changed and displayed for identification (steps F7 and F8).

Here, after the program is edited and corrected so as not to include the restricted command, the re-execution of the corrected program is instructed by operating the “EXE” key. Then, the process returns to the process from step F3, and in the re-executed program,
Further, it is determined whether or not there is a command to be restricted (steps F9 → F10, F11 → F3).

Therefore, according to the program function restriction processing and the program mode processing of the electronic computer according to the fourth embodiment (No. 5) of the above configuration, the program calculation function is specified as the restriction target function and the use of the program command is restricted. When the restriction is specified, a list of the program commands is displayed, and the arbitrarily selected use restriction command is stored in the restriction command memory 23 e in the RAM 23. Then, when an arbitrary program is created in the program mode processing and the execution thereof is started, it is determined whether or not there is a use restriction command included in the execution program. Is stopped, the restriction message 22a 'is displayed, the use restriction command is identified and displayed, and the program can be edited. Therefore, a program that performs the same operation is edited and recreated using a different command. Therefore, learning of program creation can be performed more effectively.

The Fourth Embodiment (Part 1) to (Part 4)
In the above, the time limit specified for the function to be limited is specified as the continuous time limit from the present time. However, as described in the following fourth embodiment (part 6) (see FIGS. 24 and 25). Alternatively, the time limit for the function to be limited may be set intermittently on a time table.

FIG. 24 shows a fourth embodiment (part 6) of the present invention.
6 is a flowchart showing a time table function restriction process of the electronic computing device according to the embodiment.

FIG. 25 is a diagram showing a function restriction setting display state on the time table accompanying the time table function restriction processing of the electronic computer.

When the function restriction setting key 34 provided on the apparatus main body 11 is operated, a function restriction mode control program is started, and the restriction mode memory 2 in the RAM 23 is activated.
The restriction mode flag is set for 3b (step G1).

Then, as shown in FIG. 25, a time table for setting the function restriction is displayed on the display screen of the liquid crystal display unit 13. On this time table, an arbitrary function to be restricted and its time limit are displayed. The band is input and displayed (steps G2 and G3).

When the confirm operation is performed by the "EXE" key, the time table data in which the arbitrary restriction function and the time limit are set and displayed is stored in the function restriction time table memory 23i in the RAM 23. The set function restriction process is started (step G).
4, G5).

At this time, the current time is confirmed and the data of the time table stored in the function-limited time table memory 23i in the RAM 23 is searched, and the start of the limited time zone associated with the limited function is started. It is determined whether the current time matches the time (step G).
6, G7, G8).

If it is determined that the current time does not coincide with the restriction start time of the restriction function set on the time table, it is determined whether the current time coincides with the restriction release (end) time of the restricted time zone. (Step G8 → G
9).

That is, if it is determined in step G8 that the current time coincides with the start time of the limited time zone associated with the restricted function, the restriction processing in which the restricted function cannot be used is performed. Migrated (step G8
→ G12).

If it is determined in step G9 that the current time coincides with the restriction release (end) time of the restricted time zone, the restriction of the function in the restricted state is released. Thereafter, it is determined whether or not the current time has passed the limited time zone corresponding to all the limited functions set on the time table (step G9 →
G10, G11).

Here, when it is determined that the current time has not passed the time limit corresponding to all the limit functions set on the time table, the flow returns to the processing after step G6 again. The function restriction process corresponding to the next time limit set on the time table is repeated in the same manner as described above (steps G11 → G6 to G10).

Thereafter, if it is determined that the current time has passed the time limit corresponding to all of the limit functions set on the time table, the time range of the time table function limit process is executed. Another function restriction process ends (step G11 → end).

Therefore, according to the time table function restriction processing of the electronic computer according to the fourth embodiment (No. 6) of the above configuration, the restriction target function and its restriction are displayed on the time table displayed on the liquid crystal display unit 13. When the time zone is input and set, the restriction start time and the restriction end time of the function restriction time zone on the time table are compared with the current time, and the current time is compared and determined, and the function restriction process corresponding to each time restriction zone is performed. Therefore, for example, by setting the function restriction corresponding to each of a plurality of test subjects once according to the test timetable of each test, the restriction processing of each non-permitted function according to all the test execution times is performed. be able to.

In each of the function restriction processes described in the fourth embodiment (part 1) to (part 6),
As described in the following fourth embodiment (part 7) (see FIGS. 26 and 27), the user data stored in the function data memory 23i that can be used as appropriate is changed in accordance with the execution of the function restriction. During the function restriction, a configuration may be added to save the data in a memory area that cannot be read.

FIG. 26 shows a fourth embodiment of the present invention (part 7).
13 is a flowchart showing a memory saving process at the time of function restriction of the electronic computing device according to the embodiment.

FIG. 27 is a diagram showing a data saving and restoring display state of the function data memory accompanying the memory saving process when the function of the electronic computer is restricted.

By operating the function restriction setting key 34, the control program for the function restriction mode is started, and the restriction mode flag is set in the restriction mode memory 23b in the RAM 23 (step H1). The setting of non-display is performed (step H).
2) In the same manner as in the fourth embodiment (part 1) to (part 6), the function to be restricted is selected and set, the time limit is designated and input, and the function restriction processing is executed by the “EXE” key. When the input is made, the execution of the function restriction process according to the selected and set restriction function and the restriction time is started (step H3).

Then, the contents stored in the function data memory 23j in the RAM 23 are as follows:
For example, all user data such as function formulas accumulated in the past, which are read out as shown in FIG. 27 (A), are read out, and cannot be read out while the function in the RAM 23 is restricted. The data is transferred to the memory 23k and saved (step H4).

Here, when a data call command to the function data memory 23j is input by a key operation (step H5), it is determined whether or not memory non-display is set in the step H2 (step H6). If it is determined that the memory non-display setting has not been made, the user data transferred and saved to the save data memory 23k in the step H4 is re-transferred to the function data memory 23j and returned. The data in the save data memory 23k is erased (step H6 → H7).

Then, a process of reading and displaying the user data in the function data memory 23j is appropriately performed (step H8).

On the other hand, when a data call command to the function data memory 23j is input by the key input operation (step H5), if it is determined in step H2 that the memory non-display is set, Then, the saved user data stored in the function data memory 23j is deleted (steps H6 → H9).

Then, the current time is confirmed (step H).
10) If it is determined that the time is within the function limitation time stored in the time limit memory 23d in the RAM 23, the contents of the function data memory 23j in which the user data has been saved and erased are displayed on the liquid crystal display unit. 13 (steps H11 → H12).

In this case, since there is no stored user data in the function data memory 23j, as shown in FIG. 27 (B), user data such as a function calculation formula input in the past is not displayed at all. However, it is possible to newly write and read necessary data during the function limitation as user data.

On the other hand, when it is determined that the current time confirmed in the step H10 is not within the time of the function limitation stored in the time limit memory 23d, the data is transferred to the save data memory 23k in the step H4. After the transferred user data is returned to the function data memory 23j and returned, for example, as shown in FIG.
As shown in (C), the user data in the function data memory 23j is displayed on the liquid crystal display unit 13 (steps H11 → H13, H12).

Therefore, according to the memory saving process at the time of function limitation of the electronic computer according to the fourth embodiment (No. 7) of the above configuration, the setting of the memory non-display is set in advance together with the setting of the function to be limited and the time limit thereof. Then, the user data such as various function formulas accumulated and stored in the function data memory 23j in the RAM 23 in the past are transferred to the save data memory 23k, which cannot be read during the function restriction, and are erased. If the function limit time is in effect when the user data call command is input,
The contents of the function data memory 23j in which the data has been saved and no past user data exists are read and displayed. After being returned to 23j, the user data is read out and displayed. Therefore, even if the user data in the function data memory 23j is not lost along with the execution of the function restriction processing, the calculation formula related to the restriction function is obtained. Etc. can be prevented from being read and made available.

In the fourth embodiment (part 1) to (part 7), the setting for function restriction is performed by input operation on each electronic computer in any of the electronic computers. Although the operation is performed, for example, a plurality of electronic computing devices are connected via communication means such as infrared rays or online, and the function restriction information set by the input operation on one of the electronic computing devices is transmitted to all other With a configuration in which the same function restriction setting is made by transferring to the electronic computer, the unified function restriction work on the electronic computer of all examinees at the test hall or the like can be performed very easily. .

For example, in a classroom where an electronic computing device such as a personal computer is placed online on each desk, when the use of the personal computer is permitted during the test, the function of each personal computer can be easily and easily restricted according to the contents of the test. It can be performed reliably.

Each of the methods for restricting functions in the electronic computer described in the fourth embodiment (part 1) to (part 7), that is, the time designation function restriction processing shown in the flowchart of FIG. 18, a function restriction password creation process and a function restriction setting process using a password, a time-specific function-specific restriction process shown in the flowchart of FIG. 18, a time-specific function-specific restriction display process shown in the flowchart of FIG. 20, and a flowchart shown in FIG. Each method such as the program function restriction processing and the program mode processing, the time table function restriction processing shown in the flowchart of FIG. 24, and the memory saving processing at the time of function restriction shown in the flowchart of FIG. Card (R
OM card, RAM card, etc.), magnetic disk (floppy disk, hard disk, etc.), optical disk (CD
-ROM, DVD, etc.), and can be stored in an external storage medium 28 such as a semiconductor memory and distributed. Then, the computer reads the program stored in the external storage medium 28 by a storage medium reading unit 29 such as a magnetic disk device, and the operation is controlled by the read program to thereby execute the fourth embodiment (part 1). )
The function restriction operation by time designation and the display notification operation described in (7) are realized, and the same function restriction processing by the above-described method can be executed.
