Abstract

According to one embodiment, a tax calculator displays a first tax-included amount, responding to a first input operation relating to a first tax rate, for a first numerical value indicating a tax-excluded amount; displays a second tax-included amount, responding to a second input operation relating to a second tax rate, for a second numerical value indicating a tax-excluded amount; displays a tax-included grand total amount calculated by totaling a first tax-included total amount indicating a total of the first tax-included amount, and a second tax-included total amount indicating a total of the second tax-included amount; and displays the first tax-included total amount responding to the first input operation after the tax-included grand total amount was displayed, or the second tax-included total amount responding to the second input operation after the tax-included grand total amount was displayed.

First claim

The invention claimed is:

1. A tax calculator comprising an input device, a display having a limited size and a processor, the input device including at least a first key, a second key, and a third key, the first key being operated when a process relating to a first tax rate is executed, the second key being operated when a process relating to a second tax rate is executed, and the third key being operated when a process relating to a tax calculation result is executed, the processor being configured to:
execute control to, when the first key is operated while a numerical value is displayed on the display, display on the display by switching from the numerical value displayed thereon, a tax calculation result that is calculated using the numerical value and the first tax rate,
execute control to, when the second key is operated while another numerical value is displayed on the display, display on the display by switching from the numerical value displayed thereon, a tax calculation result that is calculated using the other numerical value and the second tax rate,
execute control to display on the display by switching from any numerical value displayed thereon, a tax calculation result grand total amount in response to the third key being operated after the control to display the tax calculation result using the first tax rate is executed at least once and the control to display the tax calculation result using the second tax rate is executed at least once, the tax calculation result grand total amount being indicative of a grand total amount of a plurality of tax calculation results calculated by executing the control to display the tax calculation result more than once; and
execute control to display on the display by switching from any numerical value displayed thereon, a tax calculation result relating numeric value when one of the first key and the second key is operated after the control to display the tax calculation result grand total amount is executed, the tax calculation result relating numeric value being one of numeric values relating to the plurality of tax calculation results calculated by executing the control to display the tax calculation result more than once, the one being relating to any one of the tax calculation results, which corresponds to the operated one of the keys.

2. The tax calculator of claim 1 , wherein
the control to display the tax calculation result includes calculating any one of tax-included amounts and any one of tax amounts while setting the displayed numeric value as any one of tax-excluded amounts, using the one of tax rates, which corresponds to the operated one of the keys, and
the control to display the tax calculation result relating numeric value includes executing control to switchingly display a tax calculation result by updating a screen of the display to display any one of a total of some of the tax-included amounts, a total of some of the tax-excluded amounts, corresponding to the some of the tax-included amount, and a total of some of the tax amounts, corresponding to the some of the tax-included amounts, every time the one of the keys is operated.

3. The tax calculator of claim 1 , wherein the processor is configured to execute control to set a fraction process method by setting any one of a plurality of calculation methods of a fraction process, and
the control to display the tax calculation result, the control to display the tax calculation result grand total amount, or the control to display the tax calculation result relating numeric value includes displaying on the display a numeric value according to the tax calculation result, the tax calculation result grand total amount, or the any one of the tax computation results, by a form corresponding to any one of the calculation methods set by the control to set the fraction process method.

4. The tax calculator of claim 3 , wherein the control to set the fraction process method includes making a transition to a state in which any one of the plurality of calculation methods of the fraction process is selectable, in response to two keys being operated in combination, selecting any one of the plurality of calculation methods of the fraction process in response to another key being operated, and setting the selected one of the calculation methods of the fraction process in response to one of the two keys being operated.

5. The tax calculator of claim 1 , wherein the control to display the tax calculation result includes displaying on the display, when the one of the keys is operated, the tax calculation result and one of a first tax symbol corresponding to the first tax rate and a second tax symbol corresponding to the second tax rate, the one of the first and second tax symbols indicating that the tax calculation result is a result of a calculation using the one of the tax rates, which corresponds to the one of the keys.

6. The tax calculator of claim 1 , wherein the control to display the tax calculation result grand total amount includes displaying on the display in response to the third key being operated, the tax calculation result grand total amount and a tax total symbol.

7. The tax calculator of claim 6 , wherein
the control to display the tax calculation result includes calculating, while the displayed numeric value is set to a tax-excluded amount, a tax-included amount using the one of the tax rates, which corresponds to the operated one of the keys, and
the control to display the tax calculation result relating numeric value includes displaying on the display by updating a screen of the display, when the one of the keys is operated after the control to display the tax calculation result grand total amount is operated and while the tax total symbol is displayed, a numeric value according to one of a first tax-included amount corresponding to the first tax rate and a second tax-included amount corresponding to the second tax rate, the one of the first and second tax-included amounts being corresponding to the one of the tax rates corresponding to the operated one of the keys, as a numeric value according to the any one of the tax calculation results.

8. The tax calculator of claim 1 , further comprising a memory, wherein the memory includes a first memory region that stores information on the first tax rate, and a second memory region that stores information on the second tax rate, and
the control to display the tax calculation result includes:
calculating a tax-included amount using the one of the tax rates, corresponding to the operated one of the keys while the displayed numeric value is set to a tax-excluded amount; and
storing the calculated tax-included amount into one of the first memory region and the second memory region of the memory, the one corresponding to the one of the tax rates.

9. The tax calculator of claim 8 , wherein
the control to display the tax calculation result grand total amount includes obtaining a grand total amount of the plurality of tax-included amounts stored in the first memory region and the second memory region of the memory, and displaying on the display by updating a screen of the display, the obtained grand total amount of the tax-included amounts as the tax calculation result grand total amount, and
the control to display the tax calculation result relating numeric value includes, when the one of the keys is operated, obtaining a total of the tax-included amounts stored in one of the first memory region and the second memory region of the memory, the one corresponding to the any one of the keys, and displaying on the display by updating a screen of the display, the obtained total of the tax-included amounts as a numeric value according to the any one of the tax calculation results.
