Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
FIG. 1 is an external view showing a configuration of an electronic computer 1 according to a first embodiment to which an electronic apparatus of the present invention is applied.
When the computer 1 divides and pays the total amount to be paid (total amount of money) when, for example, a plurality of people eat and drink at a restaurant, the burden on each person according to the given conditions It is a computer that performs so-called split-account calculation for calculating the amount (expenditure amount).
In the electronic computer 1, it is possible to set a condition such as dividing a plurality of persons who bear the payment (hereinafter referred to as payers) into a plurality of groups and changing the burden amount for each group. In addition, the amount of expenditure per payer is calculated. The electronic computer 1 according to the first embodiment can divide payers into a maximum of three groups (groups 1 to 3).

As shown in FIG. 1, the electronic computer 1 is configured by arranging a display unit for displaying buttons and numerical values operated by a user on the front surface of a substantially box-shaped or substantially flat plate-shaped main body.
As shown in FIG. 1, a numeric keypad 101 for inputting numerical values is disposed on the front surface of the electronic computer 1. The numeric keypad 101 has numeric keys 0 to 9 as well as a clear key for erasing input numerical values, and an all instruction for erasing all numerical values and amounts displayed in the electronic calculator 1 and the amount display portions 110-119. It has a clear key. Further, a calculation instruction button 102 is provided on the front surface of the electronic computer 1 to instruct execution of calculation based on a numerical value input with the numeric keypad 101.

In addition, on the front surface of the electronic computer 1, an amount display unit 110-119 and a selection button 120-129 are arranged.
The monetary amount display unit 110-119 is a display unit that displays conditions input by the numeric keypad 101, calculation results, and the like. For example, the monetary amount display unit 110-119 includes an LCD panel or an organic EL panel, and displays a numerical value with a predetermined number of digits. Since the money amount display unit 110-119 displays the input number at any time during the operation of the numeric keypad 101, it may be considered to function as a kind of input box.

The amount display unit 110 displays the current total amount input by operating the numeric keypad 101. The amount display unit 111 displays the amount (payment) provided by some payers or persons not included in the payer. This amount is deducted from the payer's burden in the above-mentioned calculation of the split account.
The amount display unit 112 displays the amount paid by the payers of the group 1. The amount display unit 113 displays the number of payers in the group 1. The amount display unit 114 displays the amount paid by the payers in group 2, and the amount display unit 115 displays the number of payers in group 2. The amount display unit 116 displays the amount paid by the payers in group 3, and the amount display unit 117 displays the number of payers in group 3.
The amount display unit 118 displays the amount input as a fractional unit. This fractional unit is an amount used as a unit when calculating the payment amounts of the groups 1 to 3. For example, when the fractional unit is 500 yen, the payment amounts of the groups 1 to 3 are calculated in units of 500 yen. . The amount display unit 119 displays a fractional amount. This fractional amount is the difference between the total payment amount of all payers and the current total amount displayed on the amount display unit 110. Here, when the total amount of payments of all payers is larger than the current total amount, the fractional amount is a negative value.

When the electronic computer 1 is used, when a numerical value displayed on the money amount display unit 110-119 is input by operating the numeric keypad 101, it is necessary to select a display unit to be input. The electronic computer 1 includes selection buttons 120-129 for making this selection.
The selection buttons 120 to 129 are switches arranged side by side on the side of the money amount display units 110 to 119. The selection button 120-129 is operated when selecting a numerical value in the adjacent money amount display unit 110-119, and only one of the selection buttons 120-129 is configured to be exclusively ON. The selection buttons 120 to 129 are, for example, push button switches and have a built-in light source such as an LED. For this reason, during operation of the electronic computer 1, any one of the selection buttons 120-129 is turned on to emit light. The numerical value in the money amount display section adjacent to the ON selection button can be input with the numeric keypad 101.

In addition, a condition confirmation instructing unit 105 is disposed on the opposite side of the selection buttons 120-129 across the money amount display unit 110-119. The condition confirmation instructing unit 105 includes a confirmation instruction button 130-139 and a confirmation release button 140-149, which are respectively adjacent to the money amount display units 110-119.
The confirmation instruction buttons 130-139 are switches for confirming the numerical values displayed on the money amount display sections 110-119, respectively, and the confirmation release buttons 140-149 are the numerical values confirmed by the confirmation instruction buttons 130-139. This is a switch for returning to the unconfirmed state. The confirmation instruction button 130-139 and the confirmation release button 140-149 are constituted by push button switches, for example, and have a built-in light source such as an LED. The light source is turned on and emits light when turned on by a user operation. .
Each confirmation instruction button 130-139 and each confirmation release button 140-149 adjacent thereto are paired and are exclusively turned ON. For example, when one of the confirmation instruction button 130 and the confirmation release button 140 is configured to be turned on, and the confirmation instruction button 130 is turned on and is lit as indicated by a solid line in FIG. The release button 140 is OFF, and is turned off as indicated by a broken line in the figure.
Therefore, by turning ON the confirmation instruction button 130-139, it is possible to freely confirm the numerical value displayed on the money amount display unit 110-119. For the confirmed numerical value, the confirmation cancellation button 140-149 It is possible to return to the unconfirmed state freely by operation.

  As described above, in the electronic computer 1, the money amount display units 110 to 119, the selection buttons 120 to 129, the confirmation instruction buttons 130 to 139, and the confirmation release buttons 140 to 149 form a set one by one. Specifically, as an operation unit corresponding to the current total amount displayed on the amount display unit 110, a selection button 120, a confirmation instruction button 130, and a confirmation release button 140 are provided. The operation of inputting the numerical value displayed on the money amount display unit 110, clearing, confirming, and returning to the unconfirmed state can be executed.

The user who operates the electronic computer 1 operates the selection buttons 120 to 129 to select a numerical value as a condition for the split bill calculation, inputs the condition with the numeric keypad 101, and inputs the input numerical value with the confirmation instruction buttons 130 to 139. Confirm by operation. Then, when the necessary conditions have been input, the calculation instruction button 102 is operated to perform split bill calculation. Thereby, the numerical value displayed on the display unit that has not been determined among the money amount display units 110 to 119, that is, the expenditure amounts of the groups 1 to 3 displayed on the money amount display units 112, 114, and 116 are calculated. .
In the case where the calculated expenditure is viewed and the calculation is changed again, the user operates the confirmation release button 140-149 of the condition confirmation instruction unit 105 to shift the condition to be changed to the non-confirmed state. Let Thereafter, a condition to be newly input is selected by operating the selection buttons 120 to 129, a numerical value is input by operating the numeric keypad 101, and after the input, the condition is determined by operating the confirmation instruction buttons 130 to 139.
By repeating the above operation, the user can change the conditions as many times as necessary to perform split-account calculation.
In order to clear all conditions, the all clear key provided on the numeric keypad 101 may be operated.

FIG. 2 is a block diagram showing a functional configuration of the electronic computer 1.
As shown in FIG. 2, the electronic computer 1 controls each part of the electronic computer 1 and executes a split calculation and a program executed by the control unit 2, data related to the program, and the like in a nonvolatile manner. In accordance with the operation of the ROM 3 that stores the data, the numeric keypad 101 provided on the front of the electronic computer 1, the calculation instruction button 102, the selection buttons 120-129, the confirmation instruction buttons 130-139, and the confirmation release buttons 140-149. Is generated and output to the control unit 2, a display unit 5 for displaying a numerical value or the like on the money amount display unit 110-119 according to the control of the control unit 2, and a power source for supplying power to each unit of the electronic computer 1 Part 6.

The control unit 2 reads out and executes the control program stored in the ROM 3 to control each unit of the electronic computer 1, obtain the numerical value input by the numeric keypad 101, and execute the calculation by operating the calculation instruction button 102. Is instructed, a calculation process is performed in accordance with this instruction to calculate the amount of expenditure per payer.
In this calculation process, the control unit 2 acquires a condition determined by operating the confirmation instruction button 130-139 when the calculation instruction button 102 is operated, and detects an unconfirmed condition. Then, the control unit 2 determines whether or not the determined condition is appropriate based on a condition characteristic table 3A and the like which will be described later. If the condition is appropriate, the control unit 2 executes the calculation and outputs the calculation result. Moreover, the control part 2 sets a numerical value suitably about the conditions which are not decided based on the content set to the condition characteristic table 3A.

The operation unit 4 is connected to the numeric keypad 101, the calculation instruction button 102, the selection button 120-129, the confirmation instruction button 130-139, and the confirmation release button 140-149 of the electronic computer 1 shown in FIG. , And an operation signal corresponding to the operated button is generated and output to the control unit 2.
The display unit 5 causes the money amount display units 110 to 119 to display numerical values based on the display signal input from the control unit 2.
Moreover, the display part 5 can also display the message by a katakana, hiragana, a symbol, or a kanji in the money amount display part 110-119. For example, when the numerical value input by the ten key 101 is determined to be inappropriate by the control unit 2, a display signal for displaying a message for requesting re-input is output from the control unit 2 to the display unit 5. Is done. In this case, the display unit 5 displays a message on the amount display unit 110-119.
The power supply unit 6 incorporates various types of primary batteries, secondary batteries, fuel cells, and the like, and supplies power to each unit of the electronic computer 1. Further, the power supply unit 6 may be connected to a commercial power supply via an AC adapter, and power may be supplied to each part of the electronic computer 1 based on a DC power supply supplied by the AC adapter. Further, the power supply unit 6 may include a solar cell panel disposed on the front surface or side surface of the electronic computer 1, and power may be supplied to each unit of the electronic computer 1 by the electromotive force of the solar cell panel.

FIG. 3 is a diagram showing the configuration of the condition characteristic table 3A.
The condition characteristic table 3 </ b> A is a table that defines restrictions on handling conditions input in the electronic computer 1, and is stored in the ROM 3. In the condition characteristic table 3A, for each condition displayed on the money amount display unit 110-119, whether or not it is necessary to be confirmed at the time of calculation processing and processing to be performed when it is not confirmed are determined in association with each other.
For example, it is set that the current total amount displayed on the amount display unit 110 needs to be confirmed at the time of calculation processing. Further, whether or not the amount of money to be displayed displayed on the money amount display unit 111 is fixed at the time of calculation processing is arbitrary, and if it is not fixed, it is set to be an initial value (0 yen). The expenditure amounts and fractional amounts of groups 1 to 3 are numerical values calculated by calculation processing.

In the electronic computer 1, the condition input by the numeric keypad 101 and confirmed by the confirmation instruction button 130-139 may be inappropriate for performing the calculation.
For example, the following example is given as a case where the conditions are inappropriate.
1. The current total amount has not been finalized.
2. The current total amount was fixed at 0 yen.
3. The number of persons in group 1 or groups 1 to 3 is not fixed.
4). The number of people in group 1 or the number of people in groups 1 to 3 was confirmed with a total of 0 people.
The spending amount of a group of 5.0 people was fixed at a non-zero amount.
6). The amount of the deposit was confirmed at a higher amount than the current total amount.
7). The spending amount of one of the groups has been confirmed at a higher amount than the current total amount.
8). The fractional unit has been confirmed with an amount greater than the current total amount.
9. The fractional amount has been confirmed to be higher than the current total amount.

In the above examples 1 and 3, the conditions for calculation are insufficient. For example, it is determined that the current total amount needs to be confirmed in the condition characteristic table 3A, and the above example 1 is clearly contrary to this setting. Further, in the examples 8 and 9, the determined conditions contradict each other, and the amount of expenditure cannot be obtained. In the above examples 2, 4, and 5, the determined numerical value itself includes a contradiction, and normal calculation cannot be performed. Furthermore, in the above examples 6 and 7, it is not necessary to calculate the split payment in the first place, and it is clear that the expenditure amount is 0 yen for some or all groups.
The control unit 2 determines that the condition is not appropriate when the condition determined when the calculation instruction button 102 is operated corresponds to an example set in advance as an inappropriate example as in 1 to 10 above, for example. Judge and do not perform calculations. The basis for this determination is executed based on the condition characteristic table 3A and information stored in the ROM 3 in advance as an inappropriate example, as in 1 to 10 above. Note that examples in which the determined condition is inappropriate are not limited to the above 1 to 9, and there are other examples in which the spending amount of any group is less than a fractional unit.

As described above, among the components constituting the electronic computer 1, the numeric keypad 101 corresponds to a numerical value input operation unit, the selection buttons 120-129 correspond to a selection operation unit, and the money amount display unit 110-119 corresponds to a numerical value display unit. The confirmation instruction buttons 130 to 139 and the confirmation release buttons 140 to 149 included in the condition confirmation instruction unit 105 correspond to a confirmation operation unit, and the calculation instruction button 102 corresponds to a calculation execution instruction unit.
Functionally, the numeric keypad 101 and the selection buttons 120-129 function as condition input means together with the operation unit 4, and the confirmation instruction buttons 130-139 and the confirmation release buttons 140-149 provided in the condition confirmation instruction unit 105 are operation parts. 4 functions as a condition determination instruction unit, and the calculation instruction button 102 functions as a calculation instruction unit together with the operation unit 4.
Furthermore, in the operation described below, the control unit 2 functions as a calculation processing unit and a determination unit, and further functions as a notification unit together with the display unit 5.

FIG. 4 is a flowchart showing the operation of the electronic computer 1.
The control unit 2 inputs each condition displayed on the money amount display unit 110-119 by the operation of the numeric keypad 101 and the selection buttons 120-129, and determines how many by the operation of the confirmation instruction button 130-139 and the confirmation release button 140-149. When such a condition is confirmed (step S11) and the calculation instruction button 102 is operated (step S12), the confirmed condition is acquired and a condition that has not been confirmed is detected (step S13).

Here, the control unit 2 determines whether or not the condition acquired and detected in step S13 is appropriate as in the above-described example (step S14). If the condition is not appropriate, the control unit 2 requests re-input. A display signal for displaying a message is output to the display unit 5, and the message is displayed on any of the monetary amount display units 110-119, or on all the monetary amount display units 110-119 (step S 15). ), The process returns to step S11.
In addition, when the conditions acquired and detected in step S13 are appropriate (step S14; Yes), the control unit 2 performs calculation so as to satisfy the determined condition, and the numerical value that is the calculation target, that is, the group The expenditure amounts of 1 to 3 (excluding the group of 0 people) are calculated, and the fractional amount is calculated (step S16). In this step S16, when the expenditure amount or fractional amount of any of the groups 1 to 3 has been confirmed, another numerical value is calculated without changing the confirmed numerical value.
And the control part 2 produces | generates the display signal for displaying a calculation result, outputs it to the display part 5, and displays the numerical value obtained by calculation on the money amount display part 110-119 (step S17), and this process Exit.

The electronic computer 1 according to the present embodiment performs a calculation for obtaining the expenditure amount of each person based on the determined current total amount by the function of the control unit 2. Paying attention to the fact that each person's spending amount is not fixed, this calculation is referred to herein as a budget fluctuation type calculation.
The outline of the budget fluctuation type calculation executed by the control unit 2 is as follows.
First, if there is an unsettled condition among the amount of money to be inserted, the number of people in group 2, the number of people in group 3, and the fractional unit, the control unit 2 inputs an initial value to the condition according to the condition characteristic table 3A. .

Then, the calculation is executed based on the confirmed condition and the condition in which the initial value is input. Examples of this calculation include the following cases.
Case 1. When the number of people in groups 2 and 3 is 0, the payment amount and fractional amount of group 1 are calculated based on the current total amount, the number of people in group 1, and the determined numerical values in fractional units. In this case, the control unit 2 calculates the expenditure amount of the group 1 by dividing the current total amount by the number of people in the group 1, and if the calculated expenditure amount is smaller than the fractional unit, the expenditure amount The amount of expenditure is determined by performing a process of rounding down to the nearest whole number. Subsequently, the control unit 2 multiplies the number of people in the group 1 and the expenditure amount, and determines a difference obtained by subtracting this product from the current total amount as a fractional amount.
Case 2. If the number of people in group 2 or group 3 is not 0, based on the current total amount, the number of people in groups 1 to 3, the amount of payment in any group except the group of 0, Calculate the payment amount and fractional amount of the group that was not confirmed. In this case, the control unit 2 obtains the total payment amount of the group by multiplying the expenditure amount and the number of people for the group for which the expenditure amount is determined, and subtracts the obtained total payment amount from the current total amount to obtain the difference. Divide this difference by the number of people in the group for which the amount of expenditure has not been finalized to obtain the amount of expenditure, and if the amount of expenditure obtained is smaller than the fractional unit, round down the amount of expenditure. To determine the amount of expenditure. Subsequently, the control unit 2 multiplies the number of people and the amount of expenditure for all the groups, and determines the difference obtained by subtracting this product from the current total amount as the fractional amount.
If the fractional amount has already been finalized when performing the calculations in cases 1 and 2 above, subtract the fractional amount from the current total amount and use the subtracted value as the provisional total amount. Is divided into the spending amount of each group. Here, since the fraction of the provisional total amount should not occur, the amount of expenditure may not be calculated, for example, when the fractional unit is too large. In such a case, the control unit 2 outputs a message for interrupting the calculation and requesting re-input by the display unit 5, or changes the fractional amount.

In addition, when the fractional amount displayed in the monetary amount display unit 119 is confirmed, the fractional amount is not only fixed to the confirmed numerical value, but may be greater than or equal to the confirmed numerical value or less. . In this case, since the condition regarding the fractional amount is relaxed, the degree of freedom of calculation increases, and the number of cases where the calculation can be executed without requiring re-input.
In addition, after performing the above calculation, the control unit 2 gives a calculation instruction when the current total amount, the insertion amount, the number of people in any group, the expenditure amount of any group, the fractional unit, etc. are changed. Recalculation is performed according to the operation of the button 102.
