Description

The present invention relates to an electronic device and a calculation problem display method capable of displaying a calculation problem of a hundred calculation on a display unit and inputting an answer to the calculation problem in an input unit.

  It is considered effective to execute a simple calculation to activate the brain, and for example, a hundred calculation drill has been proposed. However, in the state of the calculation drill, paper and pencil are required, and it is troublesome that a separate scoring is required, so there is a situation where it cannot be used sufficiently and easily.

  Moreover, a mental arithmetic training machine for training mental arithmetic ability has been proposed (see, for example, Patent Document 1). According to the mental arithmetic practice machine described in Patent Document 1, it is possible to perform predetermined mental arithmetic practice. However, since the numerical display section of the calculation problem is limited to one line display, so-called one hundred calculation is facilitated. Cannot be done. In addition, since there is no input unit for inputting an answer (answer numerical value), the mental arithmetic practice machine itself cannot determine whether the answer is correct or not and cannot add up the results.

Therefore, there is a situation in which the mental arithmetic training machine described in Patent Document 1 cannot be used for hundreds of calculations.

  FIG. 2 is a block diagram showing each component block which is a function realizing unit of the electronic desk calculator according to the first embodiment of the present invention.

  The calculator 1 functions as a computer by cooperating (coordinating) with each component and each function realization means according to a program (computer program) that is preset (incorporated) to realize the calculator function and the hundred calculation function. CPU (central processing unit) 20 which implement | achieves each function of is provided.

  In addition, a timer 21 that functions as a time measuring unit, a display unit 22 as a configuration block corresponding to the display unit 4, a display control unit 23 that controls display of the display unit 22, and an input unit 24 as a configuration block corresponding to the input unit 3. , An operation number setting means 25 for setting the operation number of the operation number sequence, an operation number setting means 26 for setting the operation number of the operation number sequence, a program memory for storing a program for realizing the calculator function and the hundred calculation function ROM 27, RAM 28 functioning as a temporary storage memory for storing various data temporarily required for realizing each function, determination means 29 for determining whether the answer to the hundred percent calculation is correct, The counting means 30 for appropriately counting the number of problems (for example, the number of correct answers and the number of questions already issued) is connected to the CPU 20 via the bus 20b so as to function in cooperation with each other. Are you.

  The timer 21 is configured to measure the time that needs to be measured in accordance with the hundred calculation function. That is, the timer 21 functions in response to the time measurement required by the program.

  For example, it is preferable to measure the time from the start of the calculation question to the time when an answer is input. According to this configuration, it is possible to measure the cumulative time from the start of the calculation question to the end of answer input, and to grasp the progress of the calculation ability.

  As shown in FIG. 1, the display unit 22 (display unit 4) includes the number of operations (operation number display unit 41), the operation number sequence (operation number sequence display unit 42), the operator (operator display unit 43), and the number of operands. (Operation number display unit 44), operation number sequence (operation number sequence display unit 45), number of problems (problem number display unit 46), determination result by the determination means 29 (correct / incorrect display unit 47), difficulty (difficulty level) The display unit 48) is configured to display appropriately.

The answer to the calculation problem is input by the numerical key 3n. A display cycle setting unit 24s is provided corresponding to the slide switch 6.

  The display cycle setting unit 24 s sets a cycle (scroll time) for scrolling and displaying the calculation sequence of the hundred calculation problem corresponding to the difficulty set by the slide switch 6. That is, the degree of difficulty is set by the length of the period in which the question is displayed (the time during which the question is displayed (allowable answer time)).

  The display cycle setting means 24 s is “long cycle” when the difficulty level is set to “easy”, “normal cycle” when the difficulty level is set to “normal”, and the difficulty level is “difficult”. Is set to scroll display with a “short cycle”. In other words, since the difficulty level is defined by changing the cycle for scrolling the operation sequence, the difficulty level can be set very objectively and easily. The scroll display cycle can also be defined as the time during which one question is fixedly displayed.

  Therefore, the cycle in which the problem is displayed is defined based on the timer 21 and the display cycle setting unit 24s, and the display control unit 23 scrolls and displays the operation number sequence in synchronization with the cycle set by the display cycle setting unit 24s. It is as composition to do. For example, when the difficulty level is “easy”, the scrolling is performed later than when the difficulty level is “normal”, and when the difficulty level is “difficult”, the difficulty level is scrolled earlier than “normal”.

  In addition, the absolute value of the cycle length corresponding to the degree of difficulty may be set in the calculator 1 from the beginning, or may be set appropriately from the outside and appropriately changed according to the level of the user. It is also possible to configure as described above.

  The number-of-operations setting means 25 and the number-of-operations setting means 26 are configured so that the user can arbitrarily select the number of operations and the number of operands to set the number-of-operations sequence and the number-of-operations sequence. It is possible to create and solve numerical sequence calculation problems. That is, the operation number setting unit 25 and the operation number setting unit 26 grasp the numerical values input using the numerical key 3n of the input unit 24 as the operation number and the operation number, and form the operation number sequence and the operation number sequence. It is configured to be able to.

With this configuration, it is possible to call an incorrect answer problem (operator, number of operations, number of operands) stored in the incorrect answer problem storage unit 28e to be a calculation problem, and to perform calculation (answer input) for the incorrect answer problem. It can be executed again (recalculation mode). Therefore, it is possible to further enhance the effect of the count calculation.

  The incorrect answer problem storage unit 28e can be appropriately configured by using a part of the operator storage unit 28a, the arithmetic sequence storage unit 28b, and the operand sequence storage unit 28c.

  The question number storage means 28f is configured to store, for example, a preset number of questions (number of questions). The set number of problems is handled as the first number of problems when the remaining number of problems is obtained. Therefore, before inputting the first answer, the preset number of questions is displayed on the question number display unit 46 in a form such as “100 questions left”. Further, the number of remaining problems counted by the counting means 30 is stored.

  The already-issued problem number storage means 28g is configured to store the already-issued problem number obtained from the difference between the preset problem number and the remaining problem number counted by the counting means 30.

It may be called an answer.) The answer value is stored in correspondence with the correct answer value of the corresponding calculation problem, so that the judgment by the judging means 29 can be performed with certainty.

  The determination means 29 is configured to determine whether or not the answer value is correct (correct or incorrect answer value) by comparing the correct answer value obtained in advance for the calculation problem and the answer value input for the calculation problem.

  The counting means 30 is configured to count up the number of correct answers and count the number of correct answers. Further, the number of remaining problems is counted down to count the number of remaining problems. Further, as described above, it is also possible to count (calculate) the number of existing problems by subtracting the remaining number of problems from a preset number of problems. That is, it also has a function as calculation means.

  As described with reference to FIG. 1, the count result by the counting means 30 is displayed on the display unit 22 (specifically, the problem number display part 46) by the display control means 23 in the form of “90 more questions”, for example. It is as. As described with reference to FIG. 1, it is also possible to display in a form such as “now 8 questions” from the number of questions simply answered without subtracting the number of questions answered from the set number of questions.

In addition, the operation number “9” next to the operation number sequence is moved, and the operation number “9” is moved to the lower stage of the operation number display unit 41.

  In FIG. 11H, scroll display is further performed by moving the arithmetic sequence and the arithmetic sequence from the state of FIG. 10G, and the arithmetic operation number “9” is displayed from the arithmetic sequence display section 45 to the arithmetic operation display section. 44, the operation number sequence “12... 0” is displayed again on the operation number sequence display unit 42, and the state returned to the state of FIG. That is, a state where the operation number sequence “12... 0” is displayed so as to correspond to the operation number “9” is shown, and the operation number sequence “12... 0” with respect to the operation number “9”. Indicates that it is possible to input an answer.

  That is, when an answer to the last operation number in the operation number sequence is input, the display control means 23 scrolls the operation number sequence with the last operation number hidden, and the operation number at this time is not displayed. The next operation number included in the operation number sequence is scroll-displayed. With this configuration, it is possible to smoothly, easily, and reliably execute a hundred calculation using the calculator 1 with two lines.

  The counting means 30 subtracts the number of questions (answered) from a preset number of questions and counts the remaining number of questions. The display control unit 23 displays the counting result counted by the counting unit 30 on the problem number display unit 46 (display unit 4). The number-of-problems storage means 28f stores a preset number of problems and the remaining number of problems. The number-of-existing-problems storage means 28g stores the number of already-issued questions, thereby smoothly calculating (counting) the number of problems. It is configured to be performed.

  FIG. 4 is an explanatory diagram for explaining a display mode on the display unit when performing the one hundred percent calculation by the electronic desk calculator according to the first embodiment of the present invention. The basic configuration is the same as that shown in FIG.

  FIG. 4A shows an example of a problem of hundred calculation, in which an operation number sequence “9366417825” is displayed on the operation number sequence display unit 42, and an operation number sequence “4713825069” is displayed on the operation number sequence display unit 45. The operator “plus” is displayed as “+” on the operator display unit 43, and the contents of the problem of the hundred calculation can be grasped.

  In the arithmetic sequence (for example, “9366417825”) and the operand sequence (for example, “4713825069”), numerical values randomly generated according to a program incorporated in advance are set as initial values in the arithmetic sequence storage unit 28b and the operand sequence storage unit 28c. It can be stored and displayed as a calculation problem by reading it out as appropriate. In addition, an operator generated at random can be stored as an initial value in the operator storage means 28a, and can be displayed as a calculation problem by appropriately reading it out. Further, as will be described later, the number of operations and the number of operands can be arbitrarily set (see FIG. 7).

  From this display state, it is possible to shift to the display state shown in FIG. 3B at a speed corresponding to the cycle of scroll display, and to start counting as appropriate.

  FIG. 4B shows a state where the seventh question is displayed. In other words, since it is the seventh question, “94 more questions” is displayed in the problem number display section 46. The operation number “7”, which is the seventh operation number in the operation sequence for the first operand “4”, is displayed on the operation number display unit 41. In other words, the problem of calculating hundreds is "4 + 7".

  FIG. 4C shows a state in which the answer value “12” is inputted and confirmed as an answer to the calculation problem “4 + 7”.

  In FIG. 4D, although the answer value “12” is input as an answer to the calculation problem “4 + 7”, the correct answer value is “11”. The display control means 23 shows a state in which “wrong” is displayed on the correct / incorrect display section 47 (display section 4) based on the determination result of the determination means 29. In the present embodiment, the display mode is displayed only when “wrong” in consideration of the visibility of the display unit 4. However, the display mode may be displayed even when “correct”.

  The “Missed” display can be applied not only when an incorrect answer is entered but also when the time is up. The time-out occurs when there is no input of the answer by the numerical key 3n before the arithmetic sequence is moved by scroll display.

  In addition, when an incorrect answer is obtained, a calculation problem (an operation number “4”, an operator “+”, an operation number “7”) that is an incorrect answer is stored in the incorrect answer problem storage unit 28e. This makes it possible to perform the calculation again. By adopting a configuration capable of recalculation, it becomes possible to repeatedly practice a calculation problem that is easy to make mistakes, and it is possible to improve the calculation ability effectively and efficiently. The recalculation (recalculation mode) can be started by the recalculation key 5c as described above.

  FIG. 5 is an explanatory diagram for explaining a display mode on the display unit when executing the one hundred percent calculation by the electronic desk calculator according to the first embodiment of the present invention. Since the basic configuration is the same as that in FIGS. 3 and 4, the description thereof will be omitted as appropriate.

  FIG. 5A shows a state similar to that in FIG.

  FIG. 5B shows a state in which the eighth question is displayed. Here, “currently 8 questions” is displayed on the problem number display section 46. That is, unlike the cases of FIG. 3 and FIG. 4, the number of existing problems is displayed instead of the remaining number of problems.

  The number of already-issued problems is counted by the counting means 30, and the display control means 23 is configured to display the number of already-issued problems counted by the counting means 30 on the problem number display section 46 (display section 4). It should be noted that the number of already-issued problems can be stored in the already-issued problem number storage means 28g, and appropriately displayed when displayed on the problem number display unit 46.

  FIG. 6 is an explanatory diagram for explaining a display mode on the display unit when performing the one-hundred calculation with the electronic desk calculator according to the first embodiment of the present invention. The basic configuration is the same as that shown in FIGS.

  FIG. 6A shows a state similar to that in FIG.

  FIG. 6B shows a state in which the final question (100th question) is displayed. That is, since it is the 100th question, “0 more questions” is displayed in the problem number display section 46. As the calculation problem, the last operation number “5” corresponding to the last operation number “9” is displayed.

  FIG. 6C shows a state in which the answer to the calculation problem “9 + 5” is answered and the answer value “14” is input and confirmed.

  FIG. 6D shows a state in which the calculation problem has been completed, and shows a state in which the time required for the calculation and the wrong number of problems are displayed.

  The timer 21 as a time measuring means is configured to measure and accumulate the time from when the question of the calculation question is started until the answer is input, and to measure the accumulated result (cumulative time: elapsed time). Further, the display control means 23 is configured to display the accumulated result by the timer 21 on the display unit 4. Here, for example, a case where the accumulated result (accumulated time) is displayed as “3′42” (3 minutes 42 seconds) on the accumulated time display unit 4t provided in an appropriate column of the operand sequence display unit 45 is shown. Therefore, this configuration makes it possible to reliably grasp the progress of calculation speed.

  Further, in correspondence with the “error” shown in the correct / incorrect display portion 47, for example, the “incorrect answer count” is displayed as “16” on the incorrect answer count display portion 47c provided in the appropriate column of the arithmetic sequence display portion 42. Show the case. Therefore, with this configuration, it is possible to check the accuracy of the calculation, and it is possible to reliably grasp the calculation capability (the accuracy of the calculation). Note that the number of incorrect answers can be counted by subtracting the number of correct answers stored in the correct answer number storage means 28d from the number of set questions stored in the problem number storage means 28f. This calculation can be easily performed using the CPU 20.

  At the same time, the difficulty level display section 48 can display the difficulty level of the problem. Here, for example, it indicates that the problem is “easy”, and the level of the problem can be easily confirmed.

  FIG. 7 is an explanatory diagram for explaining a display mode on the display unit in a mode in which the problem of the hundred percent calculation is arbitrarily set by the electronic desk calculator according to the first embodiment of the present invention. The basic configuration is the same as that shown in FIGS.

  FIG. 7A shows the problem setting mode by pressing the setting key 5b to turn on the operation number (operation number sequence) and the operation number (operation number sequence) arbitrarily in the hundred calculation. A mode in which an operation number sequence and an operand sequence are specified by inputting an arbitrary value as a numerical value of a calculation problem via the numerical key 3n is shown. In other words, since the hundred percent problem can be configured by numerical values set from the outside, a voluntary usage method can be achieved.

  The numerical value input by the numerical key 3n corresponding to the number of operations is recognized by the operation number sequence setting means 25 as an operation number sequence and stored in the operation number sequence storage means 28b. The numerical value input by the numeric key 3n corresponding to the operand is recognized by the operand sequence setting means 26 as an operand sequence and stored in the operand sequence storage means 28c.

  FIG. 7B shows a state in which the set operation number sequence “7035869241” is displayed on the operation number sequence display unit 42 and the set operation number sequence “4697183025” is displayed on the operation number sequence display unit 45. In addition, the operator “minus” is displayed as “−” on the operator display unit 43, and it is possible to grasp the contents of the problem of the hundred percent calculation.

  FIG. 7C shows a state in which, after the display of FIG. 7B, the mode is shifted to the question mode at an appropriate timing according to the scroll display cycle. That is, the state shown in FIG. 3B and the like is started, and the hundred calculation is started.

  FIG. 8 is an explanatory diagram for explaining a display mode on the display unit in a mode in which the problem of the hundred percent calculation is arbitrarily set by the electronic desk calculator according to the first embodiment of the present invention. Since the basic configuration is the same as that shown in FIGS.

  FIG. 8 is a modification of FIG. In other words, in the case of FIG. 7, 100 questions are set as one hundred calculations, but the present invention is not limited to this, and an arbitrary number of questions can be set as shown in FIG. With this configuration, it is possible to set an appropriate number of problems, and an efficient calculation is possible.

  FIG. 8A is similar to FIG.

  FIG. 8B shows that the operation number sequence “93641” set using five “93641” as the number of operations is displayed on the operation number display unit 42 and the target number set using three “471” as the number of operations. The operation number sequence “471” is displayed on the operand sequence display unit 45. Therefore, the number of questions is 15 questions from the product of the number of 5 operations and the number of 3 operands, and “15 more questions” is displayed on the problem number display section 46.

  After FIG. 8B, the mode is shifted to the question mode as in FIG. 7C.

  FIG. 9 is an explanatory diagram for explaining a display mode on the display unit in a mode in which recalculation of the hundred percent calculation is executed by the electronic desk calculator according to the first embodiment of the present invention. Since the basic configuration is the same as that shown in FIGS.

  FIG. 9 shows a display mode of the display unit 4 in a state in which the recalculation mode is set in order to recalculate and calculate the problem that has been mistaken in the hundred calculation.

  FIG. 9A shows a state in which the recalculation mode is set by pressing the recalculation key 5c to turn it on. By setting the recalculation mode, the display of the incorrect answer problem is started at an appropriate timing according to the scroll display cycle.

  FIG. 9B shows a state where recalculation is started when the incorrect answer problem (number of incorrect answers) shown in FIG. 6D is “16”. Accordingly, “16 more questions” is displayed in the problem number display section 46. It also indicates that the first recalculation problem is “9 + 4”.

  FIG. 9C shows a state where the answer value “13” for the calculation problem “9 + 4” is input and confirmed.

  FIG. 9D shows a state in which the next recalculation problem “8 + 3” is appropriately displayed on the display unit 4 in accordance with the answer input in FIG. 9C.

  FIG. 10 is an explanatory diagram for explaining an example of display elements and a calculator function of the display unit of the electronic desk calculator according to Embodiment 1 of the present invention. The basic configuration is the same as that shown in FIGS.

  FIG. 10A shows a state where all display elements of the display unit 4 are displayed. As described above (see FIG. 1), the operation sequence display unit 42 corresponds to the first row as the calculator function, and the operand sequence display unit 45 corresponds to the second row as the calculator function. Both the first and second lines are configured with 10 digits, but the present invention is not limited to this, and a configuration other than 10 digits is also possible. Corresponding to each digit, a decimal point for supporting decimal calculation and a comma for displaying the number of digits are arranged. In addition, the comma is arranged on the opposite side of the decimal point (the left shoulder of each digit) in order to avoid duplication with the decimal point. In addition, operators (+, −, ×, ÷) that perform the four arithmetic operations of the calculator function and the hundred calculation are arranged in the operator display section 43.

  Further, as described above (see FIG. 1), the number-of-operations display unit 44, the number-of-problems display unit 46, the correct / incorrect display unit 47, and the difficulty level display unit 48 are arranged in order to realize the one hundred percent calculation function.

  FIG. 10B illustrates a case where multiplication is performed as a calculator function. The case where “2980 × 1.05” is calculated is displayed.

<Embodiment 2>
An electronic desk calculator according to Embodiment 2 of the present invention will be described with reference to FIGS. The configuration is basically the same as that of the first embodiment, and the same reference numerals are given to the same configuration, and description thereof will be omitted as appropriate. Also, each component block as the function realizing means can be configured in the same manner as in the first embodiment, and will be described using the configuration of FIG.

  FIG. 11 is an explanatory diagram showing a front appearance state of the electronic desk calculator according to the second embodiment of the present invention.

  In the electronic desk calculator 1s according to the present embodiment (hereinafter sometimes referred to as a calculator 1s for simplicity), the configuration of the display unit 4s is different from that of the display unit 4 of the first embodiment. The display unit 4s is configured to be capable of displaying at least three rows of numbers (numerical strings). Although the operand sequence display unit 45 of the calculator 1 according to the first embodiment is arranged corresponding to the second row, the operand sequence display unit 45s in the present embodiment includes the second row and the third row. It is arranged corresponding to the left end of the line.

  That is, the left end of the second row constitutes the operand display unit 44 as in the first embodiment, and the left end of the third row constitutes the operand sequence display 45s unlike the first embodiment. The number of operands to be calculated next to the number of operands displayed on the operand number display unit 44 is displayed.

  With this configuration, the display range of the operand sequence can be expanded, so that the contents of the questions can be grasped more clearly, and the display unit 4s of the calculator 1s capable of displaying three lines can be used effectively. It is possible to display calculation problems in an easy-to-understand manner and effectively.

  FIG. 12 is an explanatory diagram for explaining a display mode on the display unit when executing a hundred calculation with the electronic desk calculator according to the second embodiment of the present invention.

  FIG. 4A shows that the start mode 5a of the hundred calculation keys 5 is turned on by pressing the start key 5a to turn it on.

  FIG. 5B shows a state in which the first question of the hundred calculation is displayed on the display unit 4s. That is, since it is the first question, “100 more questions” is displayed in the problem number display section 46.

  The calculated operation number sequence is “12345567890”, the operation number display unit 41 displays the operation number “1”, and the operation number sequence display unit 42 displays the operation number sequence “12345567890”. Further, the operator is “plus”, and “+” is displayed on the operator display section 43, indicating that the calculation is an additive one hundred percent calculation. Further, the operand number sequence is “12...”, And the operand number display section 44 displays the operand number “1”. In addition, the operation number “2” next to the operation number “1” is displayed in the operation number sequence display section 45s.

  That is, it is displayed that the first question of the hundred calculation is “1 + 1” (number of operands “1”, operator “plus”, number of operations “1”).

  FIG. 6C shows a state in which an answer value “2” is input as the answer to the first question using the numeric key 3n and the answer input is confirmed using the equal key (=).

  FIG. 4D shows a state in which “99 questions” is displayed on the question number display section 46 and the second question is displayed because the answer input is confirmed in FIG. That is, the calculated operation number “1” is not displayed, the operation number sequence is sequentially moved to the operation number display unit 41 side, and scrolled to display the operation number “2” next to the operation number “1”. It is displayed on the display unit 41, and shows a state in which the subsequent calculation sequence “2345567890” is displayed on the calculation sequence display unit 42.

  In addition, the operation number sequence “1...” Corresponding to the next operation number “2” displayed on the operation number sequence display unit 45s is displayed following the last operation number “0” of the operation number sequence “2345567890”. It is as an aspect to do. By adopting a configuration in which the boundary of the arithmetic sequence corresponding to each operand is displayed with a comma, the calculation problem is efficiently displayed without providing an extra space.

  As shown in FIGS. 3C and 3D, the operation sequence displayed on the operation sequence display unit 42 is sequentially moved to the left by the display control means 23 and scrolled according to the input of the answer to the calculation problem. .

  FIG. 5E shows a state in which the fifth question is displayed on the display unit 4s. That is, since it is the fifth question, “96 more questions” is displayed in the problem number display section 46. The operation number “5” with respect to the operation number “1” is scroll-displayed and moved to the operation number display unit 41. In addition, an operation number sequence “1234...” Corresponding to the operation number “2” is sequentially scroll-displayed.

  FIG. 5F shows a state in which an answer value “6” is input as the answer to the fifth question using the numeric key 3n and the answer input is confirmed using the equal key (=).

  FIG. 6G shows a state in which “the remaining 95 questions” is displayed on the question number display section 46 and the sixth question is displayed at the regular position because the answer is input in FIG. . That is, the operation number sequence is scrolled to hide the solved operation number “5”, the next operation number “6” is moved to the operation number display unit 41, and the subsequent operation number sequence is displayed on the operation number sequence display unit 42. “567890”, “12345...” Are displayed.

  When the last operation number in the operation number sequence moves to the operation number display unit 41, when an answer to this operation number is input, the operation number sequence is scrolled and the first operation number in the operation number sequence is displayed in the operation number display unit 41. Is displayed again. Further, the number of operands displayed on the operand number display unit 45s is moved in correspondence with the redisplay of the operand sequence, and the operand “1” displayed on the operand number display unit 44 is hidden. The next operand “2” is displayed on the operand display section 44. In addition, the number of operands after the operand “2” (for example, “3” (see FIG. 14)) is continuously displayed on the operand sequence display section 45s.

  Note that the second row is configured as an answered display section 49 (see Embodiment 3). That is, it is possible to effectively display a calculation problem by displaying the answer status for each operation number displayed on the operation number sequence display unit 42 arranged in the first row in the second row immediately below. However, in the present embodiment, since the operation sequence is scroll-displayed, it is not necessary to use the answered display unit 49.

<Embodiment 3>
An electronic desk calculator according to Embodiment 3 of the present invention will be described with reference to FIGS. 11, 13 and 14. FIG. The configuration is basically the same as that of the second embodiment, and the same reference numerals are given to the same configuration, and description thereof will be omitted as appropriate.

  FIG. 13 is an explanatory diagram for explaining a display mode on the display unit when performing the one hundred percent calculation with the electronic desk calculator according to the third embodiment of the present invention. Since the basic configuration is the same as that of the calculator 1s shown in the second embodiment, description thereof will be omitted as appropriate.

  The difference from the second embodiment is in the display mode of the calculation number display unit (whether or not the calculation number string is scrolled). That is, in the case of the calculator 1s shown in FIG. 11, FIG. 13 and FIG. 14, the position of the operation number to be answered is displayed using the answered display unit 49 without scrolling the operation number sequence. Therefore, the calculation number display unit (41) for displaying the calculation number is sequentially moved (changed), and is described as the calculation number display unit 41s.

  13A to 13C are the same as FIGS. 12A to 12C. Note that the position of the first calculation number “1” in the calculation number sequence displayed on the calculation number display unit 42 is the first calculation number display unit 41 s.

  FIG. 13D shows a state in which “99 questions” is displayed on the question number display section 46 and the second question is displayed because the answer input is confirmed in FIG. 13C. In addition, since the scroll display of the arithmetic sequence is not executed, the display content of the arithmetic sequence display unit 42 arranged in the first row is left as it is.

  In the present embodiment, instead of scrolling display of the arithmetic sequence on the arithmetic sequence display unit 42, the second row is used as the resolved display unit 49 to display the answered state. That is, the display bar 49b (-: 8-character 7-segment display indicating that an answer has been made, for example, on the answered display section 49 corresponding to the operation number "1" for which the answer value for the calculation problem "1 + 1" is input. It can be configured by applying a central horizontal segment.) Is displayed to indicate that the number of operations has been solved.

  That is, the display bar 49b displays that the first calculation number “1” in the calculation number sequence has been answered, and the position of the second calculation number “2” is set as the calculation number display unit 41s. It is as composition to do.

  Note that the display bar 49b may be displayed when the answer is not input and the time is up. At this time, the scroll time can be applied to the time setting as in the first embodiment.

  FIG. 13E shows a state in which the sixth question is displayed on the display unit 4s. That is, since it is the sixth question, “95 more questions” is displayed in the problem number display section 46. A display bar 49b is displayed on the answered display section 49 corresponding to the operation number sequence “12345”, indicating that an answer has been made to the operation number sequence “12345”. Further, since the position of the calculation number display section 41s is clearly shown from the position of the display bar 49b, it is possible to clearly identify that the next calculation number as a calculation problem is “6”.

  FIG. 14 is an explanatory diagram for explaining a display mode on the display unit when performing the one hundred percent calculation by the electronic desk calculator according to the third embodiment of the present invention.

  FIG. 5A shows a state where the tenth question is displayed on the display unit 4s. That is, since it is the tenth question, “91 more questions” is displayed in the problem number display section 46. The display bar 49b is displayed at a position corresponding to the operation number sequence “123456789” and indicates that the operation number of the tenth question is “0”.

  FIG. 5B shows a state in which an answer value “1” is input with the numerical key 3n as an answer to the tenth question and the answer input is confirmed with the equal key (=).

  FIG. 6C shows a state in which “the remaining 90 questions” is displayed on the question number display section 46 and the eleventh question is displayed because the answer input is confirmed in FIG.

  That is, the display bar 49b displayed on the answered display section 49 is deleted, and the position of the calculation number “1” in the calculation number sequence display section 42 again corresponds to the calculation number display section 41s. In the operand sequence display 45s, the operand sequence is scrolled and the operand “2” as the operand next to the operand “1” is moved to the operand display 44. The operand number “3” next to the operand number “2” is displayed in the operand number display section 45s.

  In the first to third embodiments, the calculator 1 has been described as an electronic desk calculator. However, the calculator 1 is not limited to an electronic desk calculator, but an educational toy, a clock, an electronic dictionary, and a PDA (personal digital assist). The present invention can be applied to electronic devices having various main body functions such as mobile phones.

<Embodiment 4>
An example of a basic processing flow in a hundred calculation mode in the calculator 1 according to the first embodiment having the display unit 4 capable of displaying two rows of numbers (numerical strings) will be described as a fourth embodiment. Note that the basic processing flow can be similarly applied to the calculator 1s according to the second and third embodiments.

  The following flow example is executed by the CPU 20 functioning as a computer in cooperation with each component and each function realization means by a computer program installed in advance. The same applies to the fifth to seventh embodiments.

  FIGS. 15 and 16 are flowcharts showing an example of a basic processing flow when executing a hundred calculation in the electronic desk calculator according to the fourth embodiment of the present invention.

Step S100:
When the start key 5a is pressed and turned on, the hundred calculation mode is entered, and the hundred calculation is started.

Step S102:
The elapsed time is initialized, that is, the timer 21 is initialized. Further, the correct answer number stored in the correct answer number storage means 28d and the incorrect answer problem stored in the incorrect answer problem storage means 28e are erased and initialized.

Step S104:
The operator is displayed on the operator display unit 43, the operation sequence is displayed on the operation sequence display unit 42, the operand (the first operand on the operand sequence) is displayed on the operand display 44, and the remaining number of questions is displayed. They are displayed on the part 46, respectively. As described above, the operator is stored in the operator storage unit 28e, the operation sequence is stored in the operation sequence storage unit 28b, and the operand sequence is stored in the operand sequence storage unit 28c. The remaining number of questions is stored as the number of remaining questions in the problem number storage unit 28f.

Step S106:
Along with the start of display on the display unit 4, the measurement of elapsed time is started. That is, the timer 21 starts timing.

Step S108:
Set the scroll time according to the difficulty level. That is, the period displayed by the display period setting unit 24s is set.

Step S110:
The answer value is input by the user via the numeric key 3n.

Step S112:
The input answer value is stored in the answer value storage means 28i.

Step S114:
The mark “wrong” displayed on the correct / incorrect display 47 is deleted. Note that if the mark “Missing” is not displayed, the process proceeds to the next step.

Step S116:
The presence / absence of key input by the numeric key 3n is determined. If there is no key input (S116: YES), the process proceeds to step S128. If there is a key input (S116: NO), the process proceeds to step S118.

Step S118:
Correct value storage means for calculating the correct value corresponding to the number of operations displayed on the operation number display unit 41, the operator displayed on the operator display unit 43, and the number of operands displayed on the operand number display unit 44 Store in 28h. Note that the correct answer value can be appropriately calculated by a calculator function.

Step S120:
The correct answer value stored in the correct answer value storage means 28h and the answer value stored in the answer value storage means 28i are converted into absolute values. By performing the absolute value conversion, it is possible to cope with one hundred percent calculations for subtraction.

Step S122:
It is determined whether or not the correct answer value and the answer value are equal to each other. If equal (correct answer) (S122: YES), the process proceeds to step S130. If they are not equal (incorrect answer) (S122: NO), the process proceeds to step S124.

Step S124:
The incorrect answer problem (number of operations, operator, number of operands) is stored in the incorrect answer problem storage means 28e.

Step S126:
Since the answer is incorrect, the mark “Missing” is displayed on the correct / incorrect display portion 47. Then, it returns to step S110. That is, in such a configuration, the exercise can be continued until the correct answer is obtained.

Step S128:
Based on the measurement result of the timer 21, it is determined whether or not the scroll time has elapsed. If the scroll time has elapsed (S128: YES), the process proceeds to step S132. If the scroll time has not elapsed (S128: NO), the process proceeds to step S134.

Step S130:
The correct answer number stored in the correct answer number storage means 28d is incremented by adding "1" to the correct answer number, and the correct answer number stored in the correct answer number storage means 28d is updated. Note that the number of correct answers can be counted up by appropriately applying the counting means 30. Thereafter, the process proceeds to step S136.

Step S132:
The displayed problem (number of operations, operator, number of operands) is treated as an incorrect answer problem and stored in the incorrect answer problem storage means 28e. That is, in such a configuration, when no answer is input within the scroll time, it can be handled as an incorrect answer. Thereafter, the process proceeds to step S136.

Step S134:
The scroll time is counted down and the process returns to step S110.

Step S136:
The number of remaining questions is counted down by subtracting “1” from the number of remaining questions stored in the problem number storage means 28f, and the remaining number of problems stored in the problem number storage means 28f is updated. Note that the remaining number of problems can be counted down by appropriately applying the counting means 30.
