Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing the appearance of the electronic device 10 according to the embodiment of the present invention, and FIG. 2 is a block diagram showing a hardware configuration example of the electronic device 10.

As shown in FIG. 1, the electronic device 10 which is a portable terminal (calculator) has an input unit 11 and a display unit 12. The input unit 11 is a part that accepts a user's operation, and is composed of a plurality of keys that can be pressed. The display unit 12 is a portion that displays numbers and predetermined characters on the display screen by a liquid crystal display, an LED (Light Emitting Diode), or the like.

When each key of the input unit 11 is pressed, a signal is input to the CPU 13 from a key switch (not shown) corresponding to each key. The CPU 13 is a processor that comprehensively controls each unit of the electronic device 10 in response to a signal input from the input unit 11. Of the functional blocks related to the control of the electronic device 10, even if the functional blocks are mounted on a portion other than the hardware configuration shown in FIG. 2, the CPU 13 will be described as the main body of control for convenience of explanation.

The ROM 14 is a read-only semiconductor memory, and stores a program used for processing in the electronic device 10. The CPU 13 executes various processes described later by the program stored in the ROM 14. The RAM 15 is a randomly accessible semiconductor memory, and is used as a work area for programs and data when the CPU 13 executes a program.

The display driver 16 executes display processing of numbers and characters on the display unit 12 under the control of the CPU 13.

The electronic device 10 of the present embodiment is a calculator having a function mode for calculating according to a specific rule based on arguments, in addition to a calculator mode for normal calculation that does not depend on arguments. The contents of the functional modes described below as usage examples are suitable for medical professionals such as pharmacists, but the functional modes in the present invention are not limited to the following usage examples.

The details of the input unit 11 will be described with reference to FIG. Of the input units 11, the number key area 20, the calculation command key area 21, and the memory key area 28 shown by being surrounded by a dashed-dotted line in FIG. 1 are conceptual groups each composed of a plurality of keys.

In the number key area 20, ten number keys from 0 to 9 and a decimal point key are arranged. Each key in the number key area 20 is used as an operation means for inputting numbers in both the calculator mode and the function mode. In the second usage example (FIGS. 5 (A) and 5 (B)) of the function mode described later, a part of the keys in the numeric key area 20 is also used as a means for selecting the calculation content.

The calculation instruction key area 21 arranged on the right side of the number key area 20 is a part for selecting an operation type (four arithmetic operations, etc.) in the calculator mode and inputting operator designation data, and is addition, subtraction, multiplication, division (+,-, ×). , ÷) has each calculation key. The calculation instruction key area 21 is further provided with a remainder calculation key used for executing division that produces a remainder.

The calculated data in this embodiment includes at least operator-designated data. As the first aspect of the calculation data, the combination of the operator designation data input by the key operation of the calculation command key area 21 and the numerical value input by the key operation of the numerical key area 20 becomes the calculation data. As the second aspect of the calculation data, the calculation data may be obtained only by the key operation of the calculation instruction key area 21, that is, only the input of the operator designation data. As an example of the second aspect, there is a case where the power calculation is performed by pressing the "x" key a plurality of times. As another example of the second aspect, there is a case where the factorial calculation is performed by pressing the "x ^ 2" key which is not arranged in the input unit 11 of the electronic device 10.

At the bottom of the input unit 11, an equal key 22 is arranged between the number key area 20 and the calculation command key area 21. The equal key 22 is used as a calculation completion operation means for inputting a "=" command to complete the calculation in the calculator mode. The equal key 22 is also used for inputting a calculation execution instruction and confirming a calculation result in a function mode described later. Corresponding to such an operation system, a character display of "input / confirmation" is attached to the lower part of the equal key 22 in addition to the display of "=" on the key top of the equal key 22.

On the left side of the number key area 20, all clear (AC) key 23, clear (C) key 24, carry down key 25, sign change key 26, and off (OFF) key 27 are arranged in order from the bottom. .. The upper side of the numeric key area 20 is a memory key area 28 including three keys (MRC, M +, M−) for memory operation.

A function key 30 and a function key 31 are arranged at the uppermost stage of the input unit 11. The function key 30 is an operation means for entering a BMI (Body Mass Index) calculation mode (hereinafter referred to as a BMI calculation mode) among the function modes in the electronic device 10, and "BMI" is displayed on the key top. be. The function key 31 is an operation means for entering a date calculation mode (hereinafter, referred to as a date calculation mode) among the function modes in the electronic device 10, and has a display of "date calculation" on the key top. In this embodiment, in order to explain the calculation of BMI and the date as an example, only the function key 30 and the function key 31 corresponding to these are represented in the input unit 11, but another function mode corresponding to yet another function mode is represented. It may have the function key of.

First, as a first use example of the functional mode of the electronic device 10, a case where it is applied to the calculation of BMI will be described. BMI is a body mass index that indicates the degree of obesity calculated from the relationship between height and weight, and is calculated by BMI = w / h ² when weight (kg) is w and height (m) is h. The data including this calculation formula is stored in the ROM 14 as an application for BMI calculation.

FIG. 3 shows the relationship between the input content to the input unit 11 and the processing by the CPU 13 and the like and the display content to the display unit 12 when calculating the BMI by the electronic device 10 in steps D01 to D09. Is. It should be noted that each process of the electronic device 10 in the following description is performed by the control block (FIG. 2) centered on the CPU 13 except for the content clearly stated to be an operation by the user.

As described above, the function key 30 is a function key for entering the BMI calculation mode. As shown in FIG. 3, when the operation of the function key 30 by the user is input to the CPU 13 following the operation of the all clear key 23 (D01) by the user, the application for BMI calculation is read from the ROM 14 and the application for BMI calculation is read out. Enter the BMI calculation mode (D02).

When the BMI calculation mode is entered, "BMI calculation" indicating the type of the function mode is displayed on the upper part of the display unit 12 (D02). This display continues until the BMI calculation mode ends. The first argument (the first parameter set by the user) in the BMI calculation mode of the present embodiment is height. The display unit 12 displays "height?" Prompting for input of height, which is the first argument, and "cm" indicating a unit of height (D02).

In the process of inputting the height, the numerical value is input using each key of the numerical key area 20, and the operator designation data is input using each key of the calculation instruction key area 21.

In the usage example of FIG. 3, the user first operates the numeric keys "1" and "0". In response to the operation, "10" is stored in the RAM 15 as an input value (first numerical value), and the numerical value "10" is displayed in the numerical display area of the display unit 12 (D03). At this stage, the input value can be modified or changed by operating the clear key 24, the carry key 25, the number key area 20 and the like.

Subsequently, when the user operates the "x" key in the calculation instruction key area 21 as the input of the operator designation data, the process shifts to the process of preparing the multiplication, and the multiplication process is performed on the right side of the numerical value "10" on the display unit 12. The indicated "x" is displayed (D04). In this state, when the user operates the number key "5" as the input of the second numerical value accompanying the operator designation data, the input value "5" is stored in the RAM 15 and the number display area of the display unit 12 is displayed. The input value "5" is displayed in (D05). The operator designation data "x" in D04 and the numerical value "5" in D05 indicate that the first calculation data has been input.

Subsequently, when the user further operates the "+" key in the calculation instruction key area 21 as the input of the operator designation data, the operation based on the first calculation data (1) with respect to the previously stored input value "10". The operator specification data "x" entered second and the multiplication based on the second numerical value "5" attached to the operator) are executed. Then, the calculated value "50" as a result of the calculation is displayed in the number display area of the display unit 12 (D06). At the same time, the second input operator specification data "+" shifts to the process of preparing the addition for the displayed calculated value, and the "+" indicating the addition process is shown on the right side of the numerical value "50" of the display unit 12. Is displayed (D06). When an operation based on the next calculation data is further performed from here, the previous operation value "50" becomes the first numerical value in the next operation.

Subsequently, when the user continuously operates the number keys "1", "2", and "0" as the input of the second numerical value accompanying the operator designation data "+" input earlier, the operation is performed in response to the operation. The input value "120" is stored in the RAM 15, and the input value "120" is displayed in the numerical display area of the display unit 12 (D07). The operator designation data "+" in D06 and the second numerical value "120" in D07 indicate that the second calculation data has been input. At this stage, the input value can be modified or changed by operating the clear key 24, the carry key 25, and the number key area 20.

In this state, when the user operates the equal key 22, the operation value (first numerical value) "50" based on the first calculation data is compared with the operation based on the second calculation data (the operator entered second). Addition based on the designated data "+" and the second numerical value "120" input accompanying the operator) is performed. By the first operation of the equal key 22, a series of operations in the input state of the first argument is temporarily completed, and the numerical value "170" which is the operation result based on the second calculation data is stored in the RAM 15 and displayed. The calculated value "170" is displayed in the number display area of unit 12 (D08).

As described above, in the argument input in the function mode, it is possible to perform an operation based on the calculation data as appropriate for the input value by the user and the operation value based on the input value. In the above example, both the first calculation data and the second calculation data include operator designation data and input of numerical values (the first aspect described above), but operator designation data. The calculation may be performed using the calculation data (the second aspect described above) only by inputting the above.

At this stage, the input of height, which is the first argument, has not been finalized. When the user wants to change the numerical value of the height, based on the calculation result "170", each key of the numerical key area 20 and the calculation command key area 21, the clear key 24, the carry key 25, etc. are appropriately used. It can be changed by operating it. When the numerical value is changed, the count of the number of operations of the equal key 22 is reset, and the next operation of the equal key 22 is counted again as the first operation. That is, for the equal key 22, it is determined whether or not continuous operations have been performed, not the total number of operations.

When the user performs the second operation of the equal key 22 at the stage when the numerical value displayed on the display unit 12 becomes the desired one (the calculation is completed by the first operation of the equal key 22), The numerical value of height, which is the first argument in the BMI calculation mode, is fixed. In this way, the height input process is completed by the second operation of the equal key 22 for confirming the argument following the first operation of the equal key 22 for completing the calculation.

When the height value is determined by the second operation of the equal key 22 described above, the process transitions to the weight value input process, which is the second argument (second parameter set by the user) in the BMI calculation mode. By this transition, the display unit 12 displays "body weight?" Prompting to input the body weight, which is the second argument, and "kg", which is a unit of body weight (D09).

Although the details are omitted in FIG. 3, in the process of inputting the weight, not only the simple numerical input but also the numerical value input using each key of the numerical key area 20 and the numerical value input using each key of the numerical key area 20 are performed in the process of inputting the weight. It is possible to perform an operation on the operation value after the operation by using the calculation data including at least the operator designation data input by using each key of the calculation instruction key area 21. That is, when the calculation data is input while the first numerical value as the input value or the calculation value is displayed on the display unit 12, the calculation is executed based on the first numerical value and the calculation data, and the calculation result is displayed on the display unit. Display on 12.

In the usage example of FIG. 3, when the height value is fixed and the process transitions to the weight value input process (D09), the provisional weight value “60” is controlled to be automatically displayed. Therefore, the provisional value becomes the first numerical value immediately after the transition. Unlike this usage example, when the transition to the numerical value input process of the body weight is performed, the provisional numerical value may not be displayed and the user may be set to directly input the first numerical value.

When the user operates the equal key 22 while the calculation result is displayed on the display unit 12, the numerical value of the body weight, which is the second argument, is fixed. When the calculation is performed in the weight input process, the weight input process is performed by the second operation of the equal key 22 for confirming the argument following the first operation of the equal key 22 for completing the calculation. finish.

Although omitted in FIG. 3, the CPU 13 causes the BMI calculation process to be executed when both the height as the first argument and the weight as the second argument are determined. Specifically, in the calculation formula BMI = w / h ² , "w" is the second argument, the weight value, and "h" is the height value, which is the first argument (the value determined in cm is m). Calculate the BMI by inputting (converted to the unit). Then, the calculated BMI value is displayed in the number display area of the display unit 12.

FIG. 4 is a flow chart of control corresponding to the above BMI calculation mode. This flowchart corresponds to the input of both the height, which is the first argument, and the weight, which is the second argument.

First, the CPU 13 determines whether or not each key in the numeric key area 20 is operated (step S100).

When any key in the number key area 20 is operated (step S100: YES), the CPU 13 performs a numerical input process (step S101) to store the numerical value based on the signal from the operated key in the RAM 15. , Send an instruction to the display driver 16 to display the numerical value on the display unit 12. The numerical value input process in step S101 causes the display unit 12 to display numbers in the order in which the keys in the numerical key area 20 are operated. After the execution of step S101, the process returns to step S100.

When there is no key operation in the numeric key area 20 (step S100: NO), the CPU 13 determines whether or not each key in the calculation command key area 21 is operated (step S102).

When any key in the calculation command key area 21 is operated (step S102: YES), the CPU 13 determines whether or not the calculation data for calculation and the execution instruction of the calculation are input (step S103). The calculation execution instruction here means an execution instruction other than the operation of the equal key 22.

Here, when a numerical value is input after the operator designation data, or when a predetermined power calculation is specified by the operator designation data, it is determined that the calculation data is input (step S103: YES). ). Then, the calculation based on the calculation data is executed according to the calculation execution instruction (step S104). After the execution of step S104, an instruction is sent to the display driver 16 to display the calculated value on the display unit 12, and the process returns to step S100.

For example, as in D04 to D06 of the usage example of FIG. 3, when "x" is followed by "5", the calculation data is input, and then when the "+" key is operated, the calculation execution instruction is performed. As a result, the determination in step S103 becomes YES, and the process proceeds to the process of executing the calculation in step S104. Then, the calculated value "50" is displayed on the display unit 12.

As a calculation method based on the calculation data, there are a case where the calculation is performed in the order of the operated operator designation data and a case where the calculation is performed with priority given to the higher-order operator designation data. For example, suppose that the user operates each key of the input unit 11 in the order of "+", "5", "x", and "8" after the first input value "10".

Here, when the operation is performed in the order of the operated operator designation data, "10 + 5" is performed as the first operation, and the second operation "15 x 8" is performed based on the operation value "15". , The calculated value "120" is obtained. In this case, the calculation data corresponding to the first numerical value "10" is the operator designation data "+" and the second numerical value "5". Subsequently, the second operation based on the operator designation data "x" and the second numerical value "8" is performed with the operation value "15" as a new first numerical value.

When the operation specified by the operator of the higher order is prioritized, "5x8" is performed as the first operation, and the second operation "10 + 40" is performed based on the operation value "40" to perform the operation value. Get "50". In this case, the calculation data corresponding to the first numerical value "10" is the operator designation data "+" and the second numerical value "40" by the first operation.

In this way, the calculation based on the first numerical value and the calculated data is not limited to the case where the calculation is completed only once, and the calculation value obtained by the previous calculation is updated as the second numerical value while the calculation is performed a plurality of times. Includes. Then, the input of the calculation data when the calculation is performed a plurality of times means the input of the calculation data (acceptance processing) corresponding to the order in which the actual calculation is performed, not in the order of the operations by the user. For example, when the calculation in the function mode of the electronic device 10 is a specification that gives priority to the operator designation data of the higher order, the calculation is not performed at the time of the user's operation of "+" or "5" in the above operation example. By inputting the operator designation data "x" and "8" at a higher level than that, it is determined that the calculation data corresponding to "10" has been input (YES in step S103).

On the other hand, in the determination of step S103, when a numerical value is not input following the operator specified data (including a case where there is no numerical input following the higher-order operator specified data in the specification giving priority to the higher-order operator specified data). If there is no designation of the predetermined power calculation by the operator designation data, it is determined that there is no input of the calculation data (step S103: NO), the operator designation data is accepted (step S105), and the step Return to S100. In the reception process of operator-designated data, while preparing for calculation (storage in RAM 15) corresponding to operator-designated data, an instruction is sent to the display driver 16 to perform operators (+,-, ×, ÷, etc.). It is displayed on the display unit 12.

In the determination in step S102, when there is no key operation in the calculation command key area 21 (step S102: NO), the CPU 13 determines whether or not the equal key 22 is operated (step S106).

When the equal key 22 is not operated (step S106: NO), the calculation is not completed, and the numerical input by each key in the numerical key area 20 and the operator specification data input by each key in the calculation instruction key area 21 are allowed. Wait at.

When the equal key 22 is operated (step S106: YES), the CPU 13 determines whether or not the calculation based on the calculation data is completed (step S107).

In the determination of step S107, if the calculation based on the calculation data is in progress (step S107: YES), that is, if the equal key 22 has not been operated immediately before and the calculation completion status has not been reached, the CPU 13 performs the calculation. Execution process and display setting process (step S108) of the calculation result are performed. In the process of step S108, the calculation based on the calculated data is executed, and an instruction is sent to the display driver 16 to display the numerical value of the calculation result on the display unit 12. In the usage example of FIG. 3, the state (D08) in which the numerical value "170" is displayed on the display unit 12 corresponds to this.

If the determination in step S107 is not in the middle of calculation (step S107: NO), the process proceeds to step S109. At this stage, the user operates the equal key 22 after completing the calculation in step S108. That is, as shown in D09 of FIG. 3, it is a state in which the equal key 22 is operated for the second time. Then, the CPU 13 causes the argument determination process to be performed in step S109. In the confirmation process, the numerical value of the calculation result displayed on the display unit 12 is held in the RAM 15 as the confirmation value of the argument. Further, in step S109, as in the case of setting the weight after the height is determined in the usage example of FIG. 3, processing such as waiting for key input and switching the screen display is performed in preparation for the next argument setting. In the usage example of FIG. 3, the state (D09) in which the numerical value "60" is displayed on the display unit 12 corresponds to this.

In the above usage example of the BMI calculation mode, in the input state of the arguments (height, weight), not only the simple input of the numerical value but also the four rules of calculation for the input value and the previous operation value are performed, and the final operation is performed. Processing is performed so that the calculated value can be set as an argument. Therefore, it is possible to improve the workability of information input in the function mode (BMI calculation mode) in which a calculation process (calculation according to a specific rule based on an argument) different from the calculator mode is performed. In particular, if the individual arguments handled in the function mode are of a type that requires some kind of calculation, the arguments are calculated in advance in the calculator mode, and the recorded arguments are switched to the function mode before input. Is time-consuming. On the other hand, in this usage example, since the argument can be freely set by using the numerical input and the calculation in the function mode, the convenience is improved without the need for complicated mode switching.

As a comparative example, a case where the height is input as an argument in the conventional function mode will be described. In the input state of the argument of the conventional function mode, the control is to accept only the simple input of the numerical value. Therefore, when the same key operation as in FIG. 3 is performed on the input unit 11, the result is as follows. In the key operations of "10", "x", and "5", the input of "x" is ignored, the numerical value of "105" is input, and "105" is displayed on the display unit 12. NS. In the next key operation of "+" and "120", the input of "+" is ignored and only the numerical input of "120" is performed. As a result, the display of the display unit 12 becomes "105120". Therefore, in the conventional function mode, the user has no choice but to directly input an accurate argument as a numerical value, and when he / she wants to obtain an argument by using an operation, the processing in the function mode cannot handle it.

Further, in this usage example, in the input state of the arguments (height, weight), the calculation result is displayed on the display unit 12 (D06, D08 in FIG. 3) after the calculation is executed, and the user confirms the displayed contents. , The argument is confirmed by the operation of the equal key 22. The user only needs to be aware of the fact that "in the function mode, the argument is determined by operating the equal key 22 when displaying the calculation result", and there is no need to perform a complicated operation. When inputting arguments, the other keys in the numeric key area 20 and the calculation command key area 21 are used according to the functions of each key in the calculator mode (numeric input and operator specification data input). , There is no risk of confusion in operation. In this way, in the argument input in the function mode, it is possible to realize an operation system that is intuitively easy to use without giving a sense of discomfort to the user while improving the accuracy of the input by visually confirming the calculation result.

In addition, if there is an argument to be set next, the previous argument is confirmed by operating the equal key 22, and the display and processing for the next argument input is automatically performed. Therefore, input multiple arguments efficiently. Can be done.

Subsequently, as a second use example of the functional mode of the electronic device 10, a case where it is applied to date calculation will be described. 5 (A) and 5 (B) show the relationship between the input to the input unit 11 when calculating the date by the electronic device 10, the processing by the CPU 13 and the like, and the display on the display unit 12. Is. FIG. 5A is a usage example for calculating the period (number of days) from the base date to a predetermined date, and includes steps from D11 to D20. FIG. 5B is an example of use for calculating a date in a predetermined period (number of days) from a reference date, and includes steps D21 to D28. Data such as formulas used for date calculation are stored in ROM 14 as an application for date calculation.

First, a usage example of FIG. 5A will be described. The function key 31 in the input unit 11 is a function key for entering the date calculation mode. When the operation of the function key 31 is input to the CPU 13 following the operation of the all clear key 23 by the user (D11), the application for date calculation is read from the ROM 14 and the date calculation mode is entered (D12).

When the date calculation mode is entered, the display of "base date?" Prompting for input of the base date and the display of the date "20 yy mm dd" which is the unit of the date are displayed (D12). In addition, in the numerical value input area of the display unit 12, "20" which is the first two digits of the Christian era is displayed in advance in order to reduce the trouble of inputting the numerical value by the user. However, it is also possible to set the user to key in all the digits of the Christian era without displaying the first two digits of the Christian era.

In the date calculation mode, the user operates the equal key 22 to determine the input result and instruct the execution of the calculation. When the electronic device 10 displays the date "20 yy mm dd" on the display unit 12, "=" is displayed on the right side thereof. The display of "=" is for notifying the user that the date being displayed is determined as an input value by operating the equal key 22 while the date is being displayed.

The input of the reference date by the user is performed using each key in the number key area 20. The user inputs a 6-digit number excluding the first 2 digits of the Christian era that has been displayed in advance as a date. In the usage example of FIG. 5 (A), "200101" is input by operating the three keys in the number key area 20 in order to set the reference date to January 1, 2020. In response to the input, the date "2020-01-01" is displayed in the number display area of the display unit 12 (D13). The user only inputs a numerical value, and the hyphen between the year, month, and day is automatically displayed.

At this stage, the reference date can be corrected or changed by operating the clear key 24, the carry key 25, the number key area 20, and the like to appropriately input a series of 6-digit numbers. When the input and display of the base date are completed and the user operates the equal key 22, the date displayed on the display unit 12 is determined as the base date.

Then, the process proceeds to the state of selecting the calculation content in the date calculation mode. The calculation contents selected here are the forward date calculation process that calculates the date corresponding to the predetermined period (days) before the base date, and the backward date that calculates the date corresponding to the predetermined period (days) after the base date. There are three types: calculation processing and period calculation processing that calculates the period (number of days) from the base date to a predetermined date (either before or after).

When the user operates the equal key 22 after inputting the reference date, the determined reference date is stored in the RAM 15, and the calculation content selection screen is displayed on the display unit 12 (D14). On the calculation content selection screen, the letters "how many days ago" and the number "1" mean the forward date calculation process, the letters "how many days later" and the number "2" mean the backward date calculation process, and the period calculation process. The letter "period" and the number "3" are displayed.

On the calculation content selection screen, the user selects a desired calculation content using the numeric keys from "1" to "3" in the numeric key area 20. In the usage example of FIG. 5A, since the period calculation process is performed, the user operates the number key “3”. The selection of the period calculation process is completed by the key operation. That is, with the input reference date displayed on the display unit 12, one is selected from the three types of calculation processing by the combination of the operation of the equal key 22 and the number keys from "1" to "3". Will be done.

When the user operates the number key "3" while the calculation content selection screen is displayed on the display unit 12, the process proceeds to the state of inputting the target date to be calculated for the period from the base date, and the display unit 12 The display screen of is changed to the one for inputting the target date. Specifically, a "date?" Prompting for input of the target date and a date "20 yy mm dd", which is a unit of the date, are displayed (D15). Further, on the right side thereof, "=" meaning an equal key 22 functioning as a date input determination key is displayed (D15).

When inputting the target date, "20", which is the first two digits of the Christian era, is displayed in advance in the numerical value input area of the display unit 12, as in the case of inputting the reference date described above (D15). It is also possible to set the user to key in all the digits of the Christian era without displaying the first two digits.

The input of the target date by the user is performed using each key in the number key area 20. In the usage example of FIG. 5A, in order to set the target date to May 5, 2025, three keys in the number key area 20 are operated to input a six-digit number "250505". In response to the input, the date "2025-05-05" is displayed in the number display area of the display unit 12 (D16).

At this stage, the target date can be corrected by operating the clear key 24, the carry key 25, the key of the number key area 20, and the like to re-enter a series of 6-digit numbers. When the input and display of the target date are completed and the user operates the equal key 22, the date displayed on the display unit 12 is determined as the target date.

When the user operates the equal key 22 after inputting the target date, the calculation of the period from the base date to the target date is executed based on the base date (D13) and the target date (D16). The period (number of days) that is the result of this calculation is 1951 days, and the numerical value "1951" indicating the period is displayed in the numerical display area of the display unit 12 (D17). The numerical value "1951", which is the output result calculated in the functional mode for date calculation, becomes the first numerical value. Further, the character "Period is" indicating the meaning of the numerical value of the calculation result is displayed on the display unit 12 (D17).

It is possible to switch from the function mode for date calculation to the calculator mode for normal calculation and execute continuous calculation based on the first numerical value (output result of the function mode) displayed on the display unit 12. The transition from this function mode (date calculation mode) to the calculator mode is performed according to the input of calculation data, provided that the first numerical value as the output result in the date calculation mode is displayed on the display unit 12 (D17). Will be done. More specifically, the function mode is switched to the calculator mode by inputting the operator-specified data among the calculated data. That is, each key in the calculation command key area 21 is preset as a specific key that can be handed over to the calculator mode.

In the usage example of FIG. 5A, the calculator mode is switched by inputting the operator designation data input by the operation of the "+" key by the user. The CPU 13 reads out the calculator application stored in the ROM 14 and displays a “+” mark indicating the addition process on the display unit 12 (D18). After that, the processing is performed in the calculator mode. For example, when the user operates the number key "9" as the second numerical value following the operator designation data, "9" is displayed on the display unit 12 (D19), and then when the equal key 22 is operated, the period calculation process is performed. The operation (calculation based on the calculation data) of adding the second numerical value "9" input in the calculator mode to the calculation result (first numerical value) "1951" in the calculator mode is executed, and the calculation in the calculator mode is executed. The resulting numerical value "1960" is displayed on the display unit 12 (D20).

When performing exponentiation calculation by operating the "x" key multiple times, the calculation data is input only with the operator designation data without inputting the second numerical value by operating the number key area 20. , The calculation in calculator mode is executed.

In this way, by inheriting the calculation result in the function mode (period calculation process) to the calculator mode, continuous calculation can be performed on the calculation result in the function mode. Each key in the calculation command key area 21 is set as a specific key that can be handed over to the calculator mode, and the mode switching is automatically executed by the operation of these specific keys, so that the user can perform a special operation for mode switching. There is no need to be aware of it, and it is possible to easily and efficiently shift to continuous calculation for the calculation result.

In the electronic device 10, while the period (number of days) is displayed on the display unit 12 as the calculation result in the function mode (D17), in addition to each key in the calculation command key area 21 for shifting to the calculator mode, all clear The operation of the key 23 and the function key 31 is accepted as a valid input.

When the all clear key 23 is operated while the period (number of days) which is the calculation result is displayed on the display unit 12, the calculation result of the period and the data of the reference date are cleared from the RAM 15, and the period to the display unit 12 is displayed. The display is cleared and the date calculation mode is switched to the calculator mode.

When the function key 31 is operated while the period (number of days) of the calculation result is displayed on the display unit 12, the calculation result is deleted and the previously input reference date is displayed on the display unit 12 (D13). return. That is, it is controlled to keep the previously input base date data until the date calculation mode, which is the functional mode, is exited.

In addition, in FIG. 5A, the period calculation process when the target date is a date after the base date is illustrated, but the user can also use the period calculation process in which the target date is a date before the base date. The contents of the operation by the above and the processing of the electronic device 10 are the same as those described above. Since the content to be calculated is the period (number of days), even if the target date is a date earlier than the base date, the numerical value (D17) of the calculation result is displayed on the display unit 12 without adding "-". conduct.

Subsequently, a usage example of FIG. 5B will be described. The process from the input of the reference date to the display of the calculation content selection screen on the display unit 12 (D21 to D24) is the same as that of the usage example of FIG. 5 (A) described above, and therefore the description is omitted. do.

In the usage example of FIG. 5B, since the forward date calculation process is performed, the user operates the number key "1" while the calculation content selection screen is displayed on the display unit 12 (D24). By the key operation, the selection of the forward date calculation process is input. By this input, the electronic device 10 changes the display screen of the display unit 12 to input how many days before the reference date, and displays "how many days ago?" Prompting to input the period (D25). ). Further, on the right side thereof, "=" indicating an equal key 22 functioning as a determination key for inputting a period is displayed.

Subsequently, the user inputs a period (number of days) using each key in the number key area 20. In the usage example of FIG. 5B, the numerical value "100" is input by operating the two keys in the number key area 20 in order to calculate the date 100 days before the reference date. Correspondingly, "100" is displayed in the number display area of the display unit 12 (D26). At this stage, the input period can be modified by operating the clear key 24, the carry key 25, the number key area 20, and the like.

When the user operates the equal key 22 with the input and display of the period completed, the date 100 days before the base date is calculated based on the previously input base date (D23) and period (D26). In the usage example of FIG. 5B, the result of the calculation is September 23, 2019, and the number "2019-09-23" indicating the date is displayed in the number display area of the display unit 12 (D27). .. Further, on the upper side of the number display area on the display unit 12, the characters "100 days ago" indicating the meaning of the date, which is the calculation result, are displayed.

When the date is displayed (D27), which is the result of the forward date calculation process, even if the operator specification data is input by operating each key in the calculation instruction key area 21, the continuous calculation process is controlled so as not to proceed. Will be done.

The electronic device 10 accepts the operations of the all clear key 23 and the function key 31 as valid inputs while the date is displayed on the display unit 12 as the calculation result in the function mode.

If the all clear key 23 is operated while the date, which is the calculation result, is displayed on the display unit 12, the date calculation result and the data of the reference date are cleared from the RAM 15, and the date display on the display unit 12 is deleted. Then, it switches to the calculator mode.

When the function key 31 is operated while the date as the calculation result is displayed on the display unit 12, the state returns to the state (D28) in which the previously input reference date is displayed on the display unit 12. That is, it is controlled to keep storing the previously input reference date data until the date calculation mode, which is the functional mode, is exited.

Note that FIG. 5B exemplifies a forward date calculation process for calculating a date that goes back (past) from the base date, but a backward date calculation process that calculates a date that goes after (future) from the base date. Is basically the same control and processing as the forward date calculation process. When performing the backward date calculation process, the operation by the user is different in that the number key "2" is operated while the calculation content selection screen is displayed on the display unit 12 (D24). Regarding the display control of the display unit 12 of the electronic device 10, the characters on the period input screens (D25 and D26) are "how many days later?" And the characters on the calculation result display screen (D27) are "... days later?" The difference is that "ha" (... is the input value at D26).

FIG. 6 is a flow chart of control corresponding to the above date calculation modes. The flowchart of FIG. 6 shows the difference in processing between the case where the calculation result is a numerical value (number of days) (the period calculation process shown in FIG. 5 (A)) and the case where the calculation result is a date (the date calculation process shown in FIG. 5 (B)). The focus is on, and the process of obtaining the calculation result in each calculation process will be omitted.

When there is a key input to the input unit 11 in the date calculation mode, the CPU 13 determines whether or not the result of the calculation in the date calculation mode is being displayed on the display unit 12 (step S200).

When the calculation result is displayed on the display unit 12 (step S200: YES), the CPU 13 determines whether the content displayed on the display unit 12 is a numerical value (number of days) or not a numerical value (date). Is determined (step S201).

When the content displayed on the display unit 12 is a numerical value (number of days) (step S201: YES), the CPU 13 determines whether or not the key operated this time is a key that can be taken over to the calculator mode (step S201: YES). S202). The keys that can be handed over to the calculator mode are the keys in the calculation command key area 21 in the usage example of FIG. 5 (A).

When the key operated this time is a key that can be handed over to the calculator mode (step S202: a key that can be handed over to the calculator), the CPU 13 reads out the calculator application stored in the ROM 14 and shifts to the calculator mode. The state is set (step S203). At this time, the numerical value of the calculation result in the date calculation mode is retained without being erased. Subsequently, the application for the date calculation mode is terminated and the calculator application is started to complete the transition to the calculator mode (step S204).

Step S205 comprehensively represents the entire processing of each of the following cases that does not proceed to the transition to the calculator mode (step S203, step S204).

If the calculation result is not displayed on the display unit 12 in the determination in step S200 (step S200: NO), the CPU 13 in step S205 calculates in the date calculation mode if the calculation in the date calculation mode has not been executed. Wait until there is a key input to execute. When the calculation is being executed, the display unit 12 is controlled to display the calculation result.

In the determination of step S201, when the calculation result displayed on the display unit 12 is not a numerical value (date) (step S201: NO), the CPU 13 in step S205 can take over the key operated this time to the calculator mode. The key is not determined (step S202), but processing is performed according to the type of the key. In the usage example of FIG. 5B, the all-clear key 23 and the function key 31 are treated as valid keys at this time, and the key operated this time is the all-clear key 23 or the function key 31. If is, the content according to each key is processed in step S205. If the key operated this time is other than the all clear key 23 and the function key 31, the date is displayed on the display unit 12 and the next key input is waited for.

In the determination of step S202, if the key operated this time is a key that cannot be handed over to the calculator mode (key other than the calculation command key area 21) (step S202: key that cannot be handed over to the calculator), the CPU 13 in step S205 , While displaying the numerical value which is the calculation result on the display unit 12, the next key input is waited for without changing the numerical value.

As described above, in the electronic device 10 of the present embodiment, in the function mode for performing the BMI calculation and the date calculation, the display unit 12 shows the first numerical value (the input value or the calculated value of the first argument of the function mode, or the function mode. When the calculation data including at least the operator designation data is input when the output result) is displayed, the calculation is executed based on the first numerical value and the calculation data, and the calculation result is displayed on the display unit 12. .. In this way, it is possible to directly perform the calculation based on the output result of the function mode and display the calculation result on the display unit, and the workability of information input in the function mode of the electronic device 10 becomes excellent.

In the above-described embodiment, when the first numerical value is displayed on the display unit 12, when the calculation data including at least the operator designation data is input, the calculation is executed based on the first numerical value and the calculation data.
