BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First embodiment]
FIG. 1 is a diagram showing an example of the configuration of a computer 1 according to each embodiment. The computer 1 has a processor 11 , a memory 12 , operation keys 13 , a display driver (DD) 14 and a display 15 . The calculator 1 may be a desktop calculator, a so-called calculator. Calculator 1 may be various electronic devices having numerical calculation functions other than calculators. Also, the computer 1 may have a configuration other than that shown in FIG.

The processor 11 is a processor that controls various operations of the computer 1 . Processor 11 may be a CPU, ASIC, FPGA, or the like. Also, the processor 11 may be composed of two or more processors. The processor 11 operates as a determination unit that determines how to operate a specific operation key among the operation keys 13 . Also, the processor 11 operates as a control unit that changes the processing to be executed according to the operation method of a specific operation key.

Memory 12 includes RAM and ROM. RAM is volatile memory. The RAM is used as a work memory or the like for temporarily storing various data in the processor 11 . ROM is non-volatile memory. Various programs such as a calculation program for executing various calculation functions are stored in the ROM. The ROM also stores various specific numerical values used for numerical calculations as arguments. This particular numerical value includes, for example, a tax rate value used for tax calculation.

The operation keys 13 are various keys for the user to operate the computer 1 . When an operation using operation key 13 is accepted, an input signal corresponding to the operation is transmitted to processor 11 .

Display driver 14 drives display 15 under the control of processor 11 . The display driver 14 sends various signals necessary for driving the display 15 to the display 15 .

The display 15 is a display unit such as a liquid crystal display. The display 15 provides various displays related to the calculator function.

FIG. 2 is an external front view of the computer 1. FIG. As shown in FIG. 2, operation keys 13 and a display 15 are provided on the front of the housing of the computer 1 .

The operation keys 13 have numeric keys, operation keys, and function keys. Numerical keys are keys for inputting numerical values, and include keys corresponding to numerical values from 0 to 9, for example. The operation keys are keys for performing the four arithmetic operations, for example, keys corresponding to the operators + (addition), - (subtraction), × (multiplication), and ÷ (division), and = (operation execution) key. Function keys are keys for executing various functions of the computer 1, and include, for example, all clear key (AC key), clear key (C key), memory keys (MRC key, M+ key, M− key). . Furthermore, in the embodiment, the operation keys 13 include tax calculation keys 131 . The tax calculation key 131 is a key for performing consumption tax calculation using a preset tax rate as an argument for an input numerical value. Tax calculation includes calculation of price including tax and calculation of price without tax. In addition, the tax rate may be changed due to changes in laws, etc. The tax calculation key 131 is also used to set the tax rate corresponding to such a tax rate change.

FIG. 3 is a flow chart showing tax calculation processing of the computer 1 of the first embodiment. The processing in FIG. 3 is performed by the processor 11 executing a calculation program stored in the ROM of the memory 12 . The operation of the calculator 1 other than tax calculation processing is not particularly limited. For example, the processor 11 causes the display 15 to display calculation results according to user's key operations, and performs processing of various functions such as a memory function. Here, in explaining the processing of FIG. 3, it is assumed that some numerical value has already been input to the computer 1 and the input numerical value is being displayed on the display 15 . Numerical input can be made by means of numeric keys.

At step S1, the processor 11 determines whether or not the tax calculation key 131 has been pressed. When it is determined in step S1 that the tax calculation key 131 has not been pressed, the process of FIG. 3 ends. When it is determined in step S1 that the tax calculation key 131 has been pressed, the process proceeds to step S2.

In step S<b>2 , the processor 11 starts measuring the pressing time of the tax calculation key 131 . The pressing time may be measured by a clock (not shown) provided in the computer 1, for example.

At step S3, the processor 11 erases the display on the display 15. FIG. The process of erasing the display on the display 15 is a process for making the user aware that the normal processing of the computer 1 has shifted to the processing related to tax calculation. The process of erasing the display on the display may be omitted.

In step S<b>4 , the processor 11 determines whether or not a predetermined time has passed since the start of measuring the pressing time of the tax calculation key 131 . This predetermined time is, for example, two seconds. This predetermined time can be set arbitrarily. When it is determined in step S4 that the predetermined time has not elapsed, the process proceeds to step S5. When it is determined in step S4 that the predetermined time has passed, the process proceeds to step S8. Instead of the determination in step S4, it is determined whether or not the number of times the tax calculation key 131 has been continuously pressed has exceeded a predetermined number of times. may be performed.

In step S5, the processor 11 determines whether or not the tax calculation key 131 has been released. If it is determined in step S5 that the tax calculation key 131 has not been released, the process returns to step S4. When it is determined in step S5 that the tax calculation key 131 has been released, the process proceeds to step S6.

At step S6, the processor 11 performs tax calculation. Specifically, the processor 11 calls up the tax rate value set in advance in the ROM, and uses this tax rate value to perform the tax calculation for the numerical value entered in advance by the user. After that, the process moves to step S7. That is, when the tax calculation key 131 is pressed for a short time, i.e., the tax calculation key 131 is pressed for a short time, tax calculation is performed using a preset tax rate. Here, tax calculation includes calculation of tax-inclusive price and calculation of tax-excluded price. Which of the tax-included price calculation and the tax-excluded price calculation is performed can be set in advance by the user. Alternatively, the tax calculation key 131 may be divided into a tax-included calculation key and a tax-excluded calculation key. In this case, tax-included calculation is performed when the tax-included calculation key is pressed, and tax-excluded calculation is performed when the tax-excluded calculation key is pressed. In addition, fractions may occur as a result of tax calculation. Whether to use rounding up, rounding down, or rounding off as fraction processing can be set in advance by the user. In addition, some countries use multiple consumption tax rates. Therefore, the tax calculation key 131 may be divided into a plurality of tax calculation keys for performing tax calculation for each consumption tax rate. In this case, the ROM stores a plurality of tax rates for each tax calculation key. Then, tax calculation is performed using the tax rate corresponding to the pressed tax calculation key. Note that even if the tax calculation key 131 is divided into a tax-inclusive calculation key and a tax-excluded calculation key, even if the tax calculation key 131 is divided into a plurality of tax calculation keys for performing tax calculation for each consumption tax rate, , the process of FIG. 3 can be similarly performed.

At step S7, the processor 11 causes the display 15 to display the result of the tax calculation. After that, the process of FIG. 3 ends.

At step S8, processor 11 sets the previously entered numerical value to the value of the new tax rate. Specifically, the processor 11 updates the tax rate value stored in the ROM using the previously input numerical value. After that, the process moves to step S9. That is, when the tax calculation key 131 is pressed for a long time longer than a predetermined time, the tax rate value is set. Here, when the tax calculation key 131 is divided into a plurality of tax calculation keys for performing tax calculation for each consumption tax rate, the tax rate value corresponding to the pressed tax calculation key is updated.

In step S9, the processor 11 causes the display 15 to display a setting completion display for letting the user recognize that the tax rate value has been set. The setting completion display will be described later.

At step S10, the processor 11 erases the display on the display 15. FIG. After that, the process of FIG. 3 ends. The process of erasing the display on the display 15 is a process for making the user aware that the process of setting the tax rate has shifted to the normal process of the computer 1 .

FIG. 4 is a diagram showing the display on the display 15 when setting the tax rate in the first embodiment. First, before setting the tax rate, the user operates the numeric keys to input the desired tax rate value. At this time, the numerical value 151 input by the user is displayed on the display 15 as shown in FIG. For example, "8" is displayed as the numerical value 151 in a of FIG.

Subsequently, the user presses the tax calculation key 131 for a long time. Immediately after the tax calculation key 131 is pressed, the display on the display 15 is erased as shown in FIG. 4b.

After that, when it is determined that the tax calculation key 131 has been pressed for a predetermined time, for example, two seconds, the tax rate is set. In the example of FIG. 4, the tax rate value stored in the ROM is updated to "8" (%). After that, as shown in FIG. 4c, a setting completion display is performed. In the setting completion display, in addition to the newly set tax rate value, that is, the numerical value 151 input by the user in advance, a "TAX" display 152 indicating that the tax calculation key 131 has been pressed, and the tax rate setting are displayed. A "SET %" display 153 is displayed to indicate that it has been done. Such a setting completion display allows the user to recognize that the tax rate has been set. When the tax calculation key 131 is divided into a plurality of tax calculation keys that perform tax calculation for each consumption tax rate, the "TAX" display 152 indicates "TAX1", "TAX2", . . . It may be changed to a different display according to the tax calculation key.

After the setting completion display shown in FIG. 4c, the display on the display 15 disappears as shown in FIG. 4d. In this way, setting of the tax rate is completed.

FIG. 5 is a diagram showing the display on the display 15 during tax calculation according to the first embodiment. First, before the tax calculation, the user operates the numeric keys to input the amount of money for which the tax calculation is to be performed. At this time, the numerical value 151 input by the user is displayed on the display 15 as shown in FIG. For example, in FIG. 5a, "8" is displayed as the numerical value 151.

Subsequently, the user presses the tax calculation key 131 for a long time. Immediately after the tax calculation key 131 is pressed, the display on the display 15 is erased as shown in FIG. 5b.

Thereafter, if it is determined that the pressing of the tax calculation key 131 is released before a predetermined time elapses, for example, before two seconds elapse, tax calculation is performed. After the tax calculation is completed, the calculation result of the tax calculation is displayed on the display 15 as shown in FIG. 5c. In the result display, a numerical value 154 representing the calculation result is displayed. FIG. 5c shows an example in which a numerical value 154 representing the calculation result of a tax rate of 10% is displayed. In addition, in the example of FIG. 5c, fractions are rounded up. Furthermore, in the result display, in addition to the numerical value 154, a "TAX" display 152 indicating that the tax calculation key 131 has been pressed is displayed. When the tax calculation key 131 is divided into a plurality of tax calculation keys that perform tax calculation for each consumption tax rate, the "TAX" display 152 indicates "TAX1", "TAX2", . . . It may be changed to a different display according to the tax calculation key.

As described above, in the first embodiment, the tax calculation key 131 is assigned a plurality of operation methods. When the tax calculation key 131 is pressed for a short time as the first operating method, tax calculation is performed using a tax rate set in advance as an argument for a numerical value input in advance. Further, when the tax calculation key 131 is pressed long as the second operation method, a numerical value input in advance is set as a new tax rate value. Therefore, in the first embodiment, it is not necessary to operate a dedicated key for setting the tax rate and a dedicated mode for setting the tax rate. In addition, it is possible to easily switch between performing tax calculation and setting the tax rate by using different operation methods for one key.

[Second embodiment]
Next, a second embodiment will be described. Here, the configuration of the computer 1 in the second embodiment is the same as in the first embodiment. Therefore, description of the configuration of the computer 1 is omitted.

FIG. 6 is a flow chart showing tax calculation processing of the computer 1 of the second embodiment. In the following, the description of the same processing as in the first embodiment will be appropriately omitted or simplified. In the processing of FIG. 6 as well, it is assumed that some numerical value has already been input to the computer 1 and the input numerical value is displayed on the display 15 .

At step S21, the processor 11 determines whether or not the tax calculation key 131 has been pressed. When it is determined in step S21 that the tax calculation key 131 has not been pressed, the process of FIG. 6 ends. When it is determined in step S21 that the tax calculation key 131 has been pressed, the process proceeds to step S22.

In step S<b>22 , the processor 11 starts measuring the pressing time of the tax calculation key 131 .

In step S23, the processor 11 determines whether or not the first predetermined time has elapsed since the tax calculation key 131 was started to be pressed. This first predetermined time is, for example, 0.3 seconds. This first predetermined time can be arbitrarily set within a time shorter than the second predetermined time described later. When it is determined in step S23 that the first predetermined time has not elapsed, the process proceeds to step S24. When it is determined in step S23 that the first predetermined time has elapsed, the process proceeds to step S27.

In step S24, the processor 11 determines whether or not the tax calculation key 131 has been released. When it is determined in step S24 that the tax calculation key 131 has not been released, the process returns to step S23. When it is determined in step S24 that the tax calculation key 131 has been released, the process proceeds to step S25.

At step S25, the processor 11 performs tax calculation. After that, the process moves to step S26.

At step S26, the processor 11 causes the display 15 to display the tax calculation result. After that, the process of FIG. 6 ends.

At step S27, the processor 11 erases the display on the display 15. FIG.

In step S28, the processor 11 determines whether or not the second predetermined time has elapsed since the tax calculation key 131 was started to be pressed. This second predetermined time is, for example, two seconds. This second predetermined time can be set arbitrarily. When it is determined in step S28 that the second predetermined time has not elapsed, the process proceeds to step S29. When it is determined in step S28 that the second predetermined time has elapsed, the process proceeds to step S30.

In step S29, the processor 11 determines whether or not the tax calculation key 131 has been released. When it is determined in step S29 that the tax calculation key 131 has not been released, the process returns to step S28. When it is determined in step S29 that the tax calculation key 131 has been released, the process proceeds to step S25. That is, tax calculation is performed.

At step S30, processor 11 sets the previously entered numerical value to the value of the new tax rate. After that, the process moves to step S31.

In step S31, the processor 11 causes the display 15 to display a setting completion display for letting the user recognize that the tax rate value has been set.

At step S32, the processor 11 erases the display on the display 15. FIG. After that, the process of FIG. 6 ends.

FIG. 7 is a diagram showing the display on the display 15 when setting the tax rate in the second embodiment. First, before setting the tax rate, the user operates the numeric keys to input the desired tax rate value. At this time, the numerical value 151 input by the user is displayed on the display 15 as shown in FIG. For example, in FIG. 7a, "8" is displayed as the numerical value 151. In FIG.

Subsequently, the user presses the tax calculation key 131 for a long time. The display on the display 15 continues as shown in FIG. 7b until the first predetermined time, for example 0.3 seconds, has elapsed since the tax calculation key 131 was pressed.

After that, when it is determined that the tax calculation key 131 has been pressed for the first predetermined time, the display on the display 15 is erased as shown in FIG. 7c.

After that, when it is determined that the tax calculation key 131 has been pressed for a second predetermined time, for example, two seconds, the tax rate is set. After that, as shown in FIG. 7d, setting completion display is performed.

After the setting completion display shown in FIG. 7d, the display on the display 15 disappears as shown in FIG. 7e. In this way, setting of the tax rate is completed.

Here, in the display on the display 15 at the time of tax calculation in the second embodiment, a display duration similar to that of FIG. 7b is added between FIG. 5a and FIG. 5b. Details will be omitted.

As described above, in the second embodiment, it is determined whether the tax calculation key 131 is pressed for a short time or a long time until the first predetermined time elapses after the tax calculation key 131 is pressed. The display on the display 15 is continued for a predetermined period of time. When the tax calculation key 131 is pressed for a short period of time, the interval between the erasing of the display on the display 15 and the display of the calculation result is shortened. This short interval can cause flickering. By continuing the display on the display 15 until the first predetermined time elapses after the tax calculation key 131 is pressed, flickering of the display 15 when the tax calculation key 131 is pressed for a short period of time is suppressed.

[Modification]
A modification of the embodiment will be described. In the embodiment, two operation methods, namely, short press as the first operation method and long press as the second operation method, are assigned to the tax calculation key 131, and input is made in advance for each operation method. Different processing is performed on the numeric value. The first operating method and the second operating method may be arbitrary operating methods. For example, a short press may be assigned to the tax calculation key 131 as the first operation method, and the tax calculation key 131 and a double tap operation (continuous two-time press operation) may be assigned to the second operation method. Also, the assigned operation methods are not limited to two. In other words, three or more operation methods may be assigned to the tax calculation key 131, and different processing may be performed on numerical values input in advance for each operation method. For example, as a third operation method for the tax calculation key 131, a double-tap operation (continuous double-tap operation) is assigned. Switching between modes may be performed. As a fourth operation method for the tax calculation key 131, simultaneous pressing of the tax calculation key 131 and another key is assigned, and when the simultaneous pressing is performed, the rounding is switched according to the input numerical value. may be done. In this way, the operation method, the number of operation methods, and the processing assigned to each operation method can be appropriately set.

Also, in the embodiment, an example of application to a tax calculation key is described. On the other hand, the technology of the embodiment can be applied to various computers having operation keys for carrying out specific calculations using preset specific numerical values. Operation keys for performing such specific calculations include conversion calculation keys for performing currency conversion calculations. In this case also, when the conversion calculation key is pressed for a short time, the conversion calculation is performed for the numerical value entered in advance using the preset conversion rate, and when the conversion calculation key is long-pressed, the conversion rate value is set in advance. Assignment of processing, such as being set to an input numerical value, can be performed. Alternatively, operational keys for performing such specific calculations may include powder audit keys for performing powder audit calculations, or the like.

Furthermore, in the embodiment, the operation keys of the computer 1 are assumed to be hardware keys. On the other hand, the operation keys may be software keys operated by a touch panel or the like. In this case, the computer 1 itself may also be realized by software. That is, the computer 1 may be installed in a terminal such as a smart phone or a tablet terminal.
