The tax calculator is set to the default calculation mode after the factory inspection and shipped in this state. In this case, after the factory inspection, the packing work is performed during the power-on until the power is first turned off by the auto power-off, and then the tax calculator is powered off by the auto power-off during the packing state. As a result, when the user unpacks the computer after shipment and turns on the power for the first time, the computer is started in the default calculation mode that was set when the power was turned off.

However, in the past, during the packing work performed before the user unpacks, for example, after the factory inspection, the calculation is different from the default due to the contact with the key for switching the calculation mode while the power of the tax calculator is on. There was a case of switching to the mode. After that, while the tax calculator is in the packing state, it is powered off by auto power off in a calculation mode different from the default, but when the user unpacks and powers on for the first time, it is set at power off. Also, start in a calculation mode different from the default calculation mode. In this case, when the user unpacks and turns on the power for the first time, the operation is different from the originally intended operation of starting the computer in the default calculation mode. The above-mentioned problems occur not only in tax calculators but also in electronic devices in general, when the processing mode of electronic devices is set to the default processing mode before the packing work and then the packing work is performed. There was a risk.

In addition, not limited to factory inspection processing, the device can be set to the default processing mode according to the setting initialization processing and restart processing of all electronic devices, and some of the functions that can be executed by electronic devices can be performed. When it is preferable to retain the various processing modes that have been set for a certain period after the device is set to the restricted mode in response to the execution of the process for setting the restricted mode. There is. Even in that case, after that, after the power of the device is turned off and then turned on, various set processing modes may be canceled.

In order to solve the above problems, the electronic device of the present invention is an electronic device including a control unit capable of executing processing according to a set processing mode, and the control unit defines the processing mode. Setting to the processing mode The default mode setting process is executed, and after the execution of the default mode setting process is completed, at least for a certain period until the electronic device is first turned off, the default for changing the process mode. The processing mode is not changed even if the operation of is executed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a front view showing an external configuration of a tax calculator as an electronic device according to the present embodiment. In this embodiment, the tax calculator is realized as a calculator 10 dedicated to calculation.

In addition to being configured as a calculator 10, the tax calculator is a personal computer (with a calculation processing program implemented) having a calculation function, a tablet computer, a smartphone, a mobile phone, a touch panel PDA (personal digital assistants), an electronic book, and the like. It can be configured as a portable game machine or the like. A tax calculator such as the calculator 10 that is not equipped with physical keys (buttons) displays a software keyboard similar to the keys of the calculator 10 and executes a calculation process according to a key operation on the software keyboard. ..

The calculator 10 in the present embodiment is provided with a tax calculation function for calculating taxes at a plurality of tax rates, for example, five types of tax rates. For example, in India, five types of tax rates (0%, 5%, 12%, 18%, 28%) are used as consumption tax. Therefore, the calculator 10 in the present embodiment is suitable for tax calculation in India and the like to calculate the total amount of products in which a plurality of consumption taxes of 5 types or less are mixed.

A key input unit 11, a display unit 12, and a solar panel 13 including a plurality of keys are provided on the front surface of the calculator 10. The key input unit 11 is provided with a numerical key, a calculation key, a tax calculation function key, a function key, and a check function key. The numerical key includes, for example, a plurality of keys corresponding to each of [00] [0] to [9]. The calculation keys are used for normal calculation by four arithmetic operations, for example, [+] (addition) key 11h1, [-] (subtraction) key 11h2, [x] (multiplication) key 11h3, [÷] (division) key 11h4. , [=] (Calculation execution) includes a plurality of keys corresponding to each of the keys 11h0.

The tax calculation function keys include the tax calculation key ([GST + n (TAX-n)]) 11b, the tax calculation total key ([GST GT (GT)]) 11c, and the tax calculation mode switching key ([GST + / TAX-]). 11d is provided. Here, GST is an abbreviation for "Goods and Service Tax," which means the consumption tax in India. In addition, the character string in [] (excluding the character string in ()) indicates the character string printed on the key top of each tax calculation key 11b, and further in () in []. The character string of is conveniently indicated by the character string printed on the front surface of the housing of the calculator 10. In this specification, the same notation is used not only for the tax calculation key 11b.

Tax calculation key ([GST + n (TAX-n)]) 11b includes tax 0 calculation key ([GST + 0 (TAX-0)]) 11b0, tax 1 calculation key ([GST + 1 (TAX-1)]) 11b1, tax. 2 calculation keys ([GST + 2 (TAX-2)]) 11b2, tax 3 calculation keys ([GST + 3 (TAX-3)]) 11b3, tax 4 calculation keys ([GST + 4 (TAX-4)]) 11b4 are included. The tax 0 calculation key ([GST + 0 (TAX-0)]) 11b0 is operated to input an execution instruction for tax calculation using the tax rate 0. Similarly, tax 1 calculation key ([GST + 1 (TAX-1)]) 11b1, tax 2 calculation key ([GST + 2 (TAX-2)]) 11b2, tax 3 calculation key ([GST + 3 (TAX-3)]) 11b3, tax 4 calculation key ([GST + 4 (TAX-4)]) 11b4 is operated to input an execution instruction of tax calculation using tax rate 1, tax rate 2, tax rate 3, and tax rate 4, respectively. In the present specification, when the tax calculation key ([GST + n (TAX-n)]) 11b is expressed as described above, "n" is used instead of each numerical value from 0 to 4. In the present specification, not only the tax calculation key 11b but also any numerical value (integer of 0 to 4) that "n" can take is not particularly limited, and a specific numerical value is not specified. Instead, "n" will be used for convenience.

One tax calculation key 11b (tax n calculation key 11b to 11b4) also serves as a tax-included calculation key [GST + n] and a tax-excluded calculation key [TAX-n]. The tax calculation key 11b (tax n calculation keys 11b to 11b4) is a tax calculation key [GST + n] or a tax calculation key [GST + n] or a tax calculation key [GST + n] or It is used as a tax-excluded calculation key [TAX-n]. By sharing one tax calculation key 11b as the tax-included calculation key [GST + n] and the tax-excluded calculation key [TAX-n], the limited front area of the housing can be effectively used, and a plurality (5 types) can be used. There are keys that can execute tax-included calculation processing and tax-excluded calculation processing corresponding to each tax rate.

The default tax rate (tax rate 0 to tax rate 4) assigned to the tax calculation keys 11b (tax n calculation keys 11b to 11b4) is preset at the time of factory shipment of the calculator 10. For example, the tax n calculation keys 11b to 11b4 are set with five types of tax rates (0%, 5%, 12%, 18%, 28%) according to their use in India. Further, the tax rate (tax rate 0 to tax rate 4) assigned to the tax n calculation keys 11b to 11b4 can be arbitrarily set by the user operation.

In the calculator 10 of the present embodiment, when the battery is replaced before shipment from the factory, the factory inspection program (tax rate automatic setting program) is applied to the plurality of tax calculation keys 11b (tax n calculation keys 11b to 11b4). Executes the tax rate automatic setting process that sets the preset tax rate. As a result, the tax rate setting work for the tax calculation key 11b before shipment from the factory is streamlined. On the other hand, the calculator 10 sets a tax rate that makes it easy to see that the tax rate set in the tax calculation key 11b is different from that before the battery replacement when the battery is replaced at the time of use by the user after shipment from the factory. In the present embodiment, when the battery is replaced during use by the user, the tax rate set in the tax calculation key 11b is set to, for example, "0%" (tax rate setting clear). As a result, even if the tax calculation is executed by the operation of the tax calculation key 11b, the input value and the value after the tax calculation are the same, and it is easy that the default tax rate is not set for the tax calculation key 11b. Can be recognized.

Further, the calculator 10 in the present embodiment is shipped after the factory inspection, and when the user unpacks the calculator 10 and turns on the power for the first time, a control process is performed to ensure that the calculator 10 is started in the default calculation mode. Execute. The control unit of the calculator 10 is surely started in the default calculation mode after shipment by executing any of the first control method, the second control method, or the third control method after the factory inspection. To do so.

In the first control method, when the control unit executes a certain process (factory inspection process) before shipping from the factory, the control unit sets the calculation mode (tax calculation mode) to the default calculation mode (for example, tax-included calculation mode). Even if the default operation for changing the calculation mode (for example, the normal operation of the tax calculation mode switching key 11d) is executed at least for a certain period after the execution of a certain process is completed until the power is first turned off. , Controls to keep the default calculation mode without changing the calculation mode.

In the second control method, when a certain process (factory inspection process) is executed, the control unit sets the calculation mode to the default calculation mode (for example, the calculation mode including tax), and first after the execution of the certain process is completed. When the power of the calculator 10 is turned off, the calculation mode setting process for resetting the calculation mode to the default calculation mode is executed. Then, when the power of the calculator 10 is turned off for the second time or later after the execution of a certain process is completed, the control unit does not execute the calculation mode setting process for resetting to the default calculation mode, and before the power is turned off. Holds the calculation mode (processing mode when the power of the electronic device is turned off) set by the operation of.

In the third control method, when a certain process (factory inspection process) is executed, the control unit sets the calculation mode to the default calculation mode (for example, the calculation mode including tax), and first after the execution of the certain process is completed. When the power of the calculator 10 is turned on from off, the calculation mode setting process for resetting the calculation mode to the default calculation mode is executed. Then, when the power of the calculator 10 is turned on from the second time after the execution of a certain process is completed, the control unit does not execute the calculation mode setting process for resetting to the default calculation mode, and the power is turned off. Holds the calculation mode (processing mode when the power of the electronic device is turned on from off) set by the operation before the operation.

Details of the first control method, the second control method, and the third control method will be described later. The control unit of the calculator 10 executes any of the first control method, the second control method, or the third control method after the factory inspection, so that the user can use the calculator 10 for the first time after shipment. Is started in the default calculation mode, but if the calculation mode is changed by user operation after that, the next time the power is turned on, the power was turned off last time, which was set by the user operation. Start in the calculation mode when.

The tax calculation total key ([GST GT (GT)]) 11c is a grand total key ([GT] key) for displaying the grand total for ordinary calculations (basic calculations) such as four arithmetic operations and constant calculations, and tax calculation. It also serves as a GST grand total key ([GST GT] key) for displaying the total of the calculation results of. When the tax calculation total key 11c functions as the GST grand total key, the tax calculation is executed and the processing mode of the calculator 10 shifts to the tax total recall mode (GST GT recall mode). On the other hand, when the tax calculation total key 11c functions as the grand total key, the processing mode of the calculator 10 does not particularly change, and the numerical value stored in the total memory area 22h is simply called and displayed on the display unit 12. Will be done.

The tax calculation total key 11c functions as either a grand total key ([GT] key) or a GST grand total key ([GST GT] key) depending on the operating state immediately before the tax calculation total key 11c is operated. To do. That is, for example, when the tax calculation total key 11c is pressed immediately after the tax calculation is executed by the operation of the tax calculation key 11b, the tax calculation key 11b displays the total total for the calculation result of the tax calculation. It functions as a grand total key ([GST GT] key). Further, for example, when the tax calculation total key 11c is pressed immediately after the normal calculation is executed by the operation of the calculation execution key ([=] key) 11h0, that is, the tax calculation is executed by the operation of the tax calculation key 11b. If not immediately after, the tax calculation key 11b functions as a grand total key ([GT] key) for displaying the grand total for the normal calculation (basic calculation). The pressing time of the tax calculation total key 11c here is shorter than an arbitrary predetermined time, and is shorter than the "long pressing" described below. Further, pressing for a short time is described in the present specification as "short pressing" or a normal pressing operation for convenience.

Further, the tax calculation total key 11c functions as a key opposite to the above when an operation different from the normal pressing operation (for example, long pressing) is performed. That is, for example, when the tax calculation total key 11c is pressed and held immediately after the tax calculation is executed by the operation of the tax calculation key 11b, the tax calculation total key 11c is used as the grand total key ([GT] key). Function. Further, for example, when the tax calculation total key 11c is long-pressed immediately after the normal calculation is executed by the operation of the calculation execution key ([=] key) 11h0, that is, the tax calculation is executed by the operation of the tax calculation key 11b. If not immediately after the tax calculation total key 11c, the tax calculation total key 11c functions as a GST grand total key ([GST GT] key). In addition, as an operation different from the usual operation for the tax calculation total key 11c, it is also possible to use an operation other than the above-mentioned long-pressing operation (the operation of continuing the pressed state for a predetermined arbitrary time or more described above). Is.

The function keys include, for example, an all clear key ([AC] key 11a), a clear key ([C] key), a plurality of memory keys ([MRC] [M-] [M +]), and a root key ([√] key). ), [%] key 11g and the like are included. The [AC] key 11a is used as a clear key for clearing the displayed numerical value (displaying "0") in a normal calculation process. Further, the [AC] key 11a is used as a power-on key for turning on the power when the calculator 10 is in the power-off state. The [AC] key 11a is used as a power off key for turning off the power by an operation in combination with another predetermined key (for example, the [SHIFT] key) when the calculator 10 is in the power on state. It is also possible to do. Further, when the [AC] key 11a is in the factory inspection mode set for factory inspection before shipment from the factory, the factory inspection mode is terminated and the mode is shifted to the normal mode for performing normal calculation processing. It is used as a mode switching key for. The [%] key 11g is used for the percentage calculation, and the tax rate for setting the tax rate corresponding to each of the tax calculation keys 11b (tax n calculation keys 11b to 11b4) to the value input by the key operation. Used to initiate the configuration process.

The check function key is a key used in the check function for confirming / correcting the contents of the previously executed calculation. The check function key includes a confirmation key ([CHECK BACK] key 11e, [CHECK FOWARD] key 11f) and a correction key ([CORREC] key) 11k. The [CHECK BACK] key 11e and the [CHECK FOWARD] key 11f are keys for switching and displaying the contents (calculation data) of the previously executed calculation in step units. When the [CHECK BACK] key 11e is operated, the display is switched to the calculation data of the step in the direction with a small number of steps, and when the [CHECK FORWARD] key 11f is operated, the calculation data of the step in the direction with a large number of steps is displayed. Switch the display. The unit of one step is "number + function" input for calculation. The "function" stores the code of the key operated for the four arithmetic operations, tax-included calculation, tax-excluded calculation, and the like. The correction key 11k is a key for instructing correction of the calculation content (“number + function”) displayed by the operation of the [CHECK BACK] key 11e or the [CHECK FOWARD] key 11f. By inputting the content of the calculated calculation after the operation of the correction key 11k, it is possible to correct the previously input calculation data displayed.

The switching of the tax total recall mode on / off is not limited to the operation of the tax calculation total key 11c and the [AC] key 11a. For example, the tax total recall mode may be switched on / off according to another key operation or the processing result of the calculator 10.

When the total tax recall mode is on, each time the total tax calculation key 11c is operated (pressed), the total amount including tax, the total amount excluding tax, and the tax stored in the total memory area 22g of the total tax excluding tax rate. The total amount can be switched and displayed. In addition, when the total tax recall mode is on, each time the tax calculation key 11b (tax n calculation keys 11b to 11b4) is operated (pressed), the tax is stored in the tax total memory area 22d. The total amount, the total amount excluding tax, and the total amount of tax can be switched and displayed.

The on state of the tax total recall mode is maintained even when the numerical key and the calculation key of the key input unit 11 are input. Therefore, the normal calculation using the numerical key and the calculation key can be executed while displaying and confirming the result of the tax calculation by the input operation of the tax calculation total key 11c or the tax calculation key 11b (11b0 to 11b4). In the normal calculation in the on state of the tax total recall mode, the numerical value as the result of the tax calculation can be displayed on the display unit 12, and the four arithmetic operations can be executed on the figurative number displayed on the display unit 12. ..

The tax calculation mode area 22m stores tax calculation mode data indicating whether the tax calculation mode is in the tax-included calculation mode or the tax-excluded calculation mode, which is switched according to the input operation to the tax calculation mode switching key 11d.

In the buffer memory area 22n, the number of units input so as to form a unit in combination with the last input function is stored. Further, in the display memory area 22p, the numerical value displayed on the display unit 12 at that time is stored. For example, when the numerical value "100" is sequentially operated as a number and the tax 1 calculation key ([GST + 1 (TAX-1)]) 11b1 is sequentially operated as a function by the operation of the numerical key, the number is set in the buffer memory area 22n. The numerical value "100" is stored, and the numerical value "105" displayed on the display unit 12 as a result of the tax-included calculation of the tax rate 1 is stored in the display memory area 22p (however, the tax rate 1 is set to 5%). if you did this). In this way, the numerical values stored in the buffer memory area 22n and the display memory area 22p are sequentially overwritten and updated according to the latest input operation.

Next, the operation of the calculator 10 in this embodiment will be described. FIG. 3 is a flowchart showing a process executed before the calculator 10 is shipped from the factory in the present embodiment, and FIG. 4 is a flowchart for explaining a first control method of the calculator 10 in the present embodiment. 5 and 6 are flowcharts showing the details of the switching key processing shown in the flowchart of FIG. FIG. 7 is a diagram showing a key operation and a display example for explaining a specific processing content.

First, the description starts from the process executed by the calculator 10 before the factory shipment.

The calculator 10 in the present embodiment is shipped after various operation checks are performed by a factory inspection process and the battery in the power supply unit 26 is replaced with a new one. Before the factory inspection, the post-factory inspection flag in the post-factory inspection flag area 22c is off.

The CPU 21 determines whether or not it has been started by replacing the battery (step S1). This determination may be made based on the result of detecting the voltage supplied from the power supply unit 26. Here, if the startup is not accompanied by battery replacement (step S1: No), the CPU 21 executes the process of step S5 described later. On the other hand, when the battery is started by replacing the battery (step S1: Yes), the CPU 21 executes the full initialization process (step S2).

In the entire initialization process, the CPU 21 clears all the contents of the memory 22 including the tax rate storage area 22e and the display contents of the display unit 12. That is, in the total initialization process, the CPU 21 clears all of the total tax rate memory area 22d, the tax rate storage area 22e, the total tax memory area 22g, the total memory area 22h, the buffer memory area 22n, and the display memory area 22p of the memory 22. To do. Further, the CPU 21 turns off the total tax recall mode flag stored in the total tax recall mode area 22k. When the battery is replaced from the state where the numerical value such as the tax calculation result is displayed, the CPU 21 clears the numerical value displayed earlier and displays "0". Further, when the battery is replaced from the state where the previous symbol is displayed in the status display area of the display unit 12, the CPU 21 clears the previously displayed symbol and hides it.

As described above, in the full initialization process involving battery replacement, the tax rate storage area 22e is also cleared, so that the tax rates 0 to 4 set for the plurality of tax calculation keys 11b are also cleared. Here, when the tax rate storage area 22e is cleared, all of the tax rates 0 to 4 are assumed to be "0".

Next, the CPU 21 refers to the post-factory inspection flag area 22c and determines whether the post-factory inspection flag indicates that the factory inspection process has been executed (the post-factory inspection flag is on) (step S3). Here, as described above, since the flag is not turned on after the factory inspection (step S3: No), the CPU 21 is in the standby state for the input operation.

Here, when the execution of the factory inspection process is instructed by the operation on the key input unit 11 (step S5: Yes), the CPU 21 executes the factory inspection process (step S6). The execution of the factory inspection process is extremely unlikely to be operated, for example, when the user normally uses the calculator 10, for example, a combination of a plurality of keys (for example, 3 or more keys), or a long press. It shall be instructed by operating in combination with key operations (such as pressing and holding the [AC] key 11a). That is, the factory inspection process is executed only in the factory before shipment. Specifically, as shown in the key operation of (A) in FIG. 7, when the [+] [5] [M +] keys are simultaneously pressed and the [AC] key 11a is pressed for a long time, the factory inspection process is performed. Determine that execution was instructed.

The CPU 21 causes each unit to perform an operation for confirming whether or not each part constituting the calculator 10 is operating normally by a factory inspection process. For example, the CPU 21 causes the liquid crystal display unit constituting the display unit 12 to turn on, blink, turn off, and the like to check the operation. Specifically, as shown in FIG. 7A, "888888888" is displayed on the main display unit of the display unit 12, "188" is displayed on the number of steps 12a, and the symbol display is fully lit. Therefore, on the tax calculation mode symbol 12b, both the symbol [GST +] indicating the tax-included calculation mode and the symbol [TAX-] indicating the tax-excluded calculation mode are displayed at the same time. Further, the CPU 21 switches the operating clock between high speed and low speed, and checks each operating state. In addition, the CPU 21 executes an operation check of each unit.

Here, when the CPU 21 is instructed to end the factory inspection process by operating the [AC] key 11a (step S7: Yes), the CPU 21 executes the calculation mode setting process at the timing of ending the factory inspection process, and performs a default tax. The calculation mode is set (step S9). In the present embodiment, the default tax calculation mode is, for example, a tax-included calculation mode. In the present embodiment, the tax calculation mode (processing mode) set at the timing of ending the factory inspection processing (predetermined processing) is referred to as a default tax calculation mode (default processing mode). .. In this case, the CPU 21 stores the tax calculation mode data indicating the tax-included calculation mode in the tax calculation mode area 22m. Further, the CPU 21 turns on the post-factory inspection flag in the post-factory inspection flag area 22c so as to indicate that the factory inspection process has been executed (step S10).

In response to the operation of the [AC] key 11a, the CPU 21 displays "0" on the main display unit and "0" on the number of steps 12a, as shown in (A) of FIG. 7, for example, in the tax calculation mode. The symbol "GST +" indicating the tax-included calculation mode is displayed on the symbol 12b (the symbol [TAX-] is deleted).

In this way, after checking the operation by the factory inspection process, the CPU 21 turns on the flag after the factory inspection and executes the key input waiting process (step S11). The details of the key input waiting process will be described later.

On the other hand, when the execution of the factory inspection process is not instructed in step S5 (step S5: No), the CPU 21 executes a normal calculation process (hereinafter, may be referred to as a conventional process) by the calculation process program 22b (hereinafter, may be described as a conventional process). Step S8). The CPU 21 executes processing according to a key operation on the key input unit 11.

Next, the process executed by the calculator 10 when the battery of the calculator 10 is replaced after the operation is checked by the factory inspection process before shipping from the factory will be described.

When the CPU 21 is started by replacing the battery (step S1: Yes), the CPU 21 again executes the full initialization process in the same manner as described above (step S2).

Next, the CPU 21 refers to the post-factory inspection flag area 22c and determines again whether the post-factory inspection flag indicates that the factory inspection process has been executed (the post-factory inspection flag is on) (step S3). In this case, as described above, since the post-factory inspection flag is set to on after the factory inspection process is executed (step S10), the CPU 21 determines that the post-factory inspection flag is on (step S3: Yes). , The tax rate automatic setting process is executed (step S4).

In the tax rate automatic setting process, the CPU 21 sets preset tax rates 0 to 4 for each of the tax calculation keys 11b (tax n calculation keys 11b to 11b4). In the present embodiment, the CPU 21 sets "0" for each of the tax rates 0 to 4, according to the five types of tax rates (0%, 5%, 12%, 18%, 28%) used in India. The numerical values of "5", "12", "18", and "28" are stored in the tax rate 3 total memory area 22e. The numerical value indicating the tax rate 0 to 4 in which the tax rate storage area 22e is set in the tax rate automatic setting process is set in advance in the calculation processing program 22a, for example, and is automatically set by the processing by the calculation processing program 22a.

Therefore, if the factory inspection process is executed before the calculator 10 is shipped from the factory, the operator performs a key operation on the calculator 10 to perform a plurality of tax calculation keys 11b (tax n calculation keys 11b0 to 0). Even if the work of setting the tax rate as the default initial value is not performed for each of 11b4), the default tax rates 0 to 4 are set for the plurality of tax calculation keys 11b. Further, in this state, since the default tax rate is set for the tax calculation key 11b, the default tax calculation can be performed by operating the tax calculation key 11b.

After completing the tax rate automatic setting process, the CPU 21 executes the key input waiting process (step S11). As will be described in detail later, in the key input waiting process, when the power is first turned off by the APO function after the factory inspection, the post-factory inspection flag in the post-factory inspection flag area 22c is turned off (step A4 in FIG. 4, FIG. Step E3) of 9 or, after the factory inspection, the power is first turned off by the APO function, and then the post-factory inspection flag in the post-factory inspection flag area 22c is turned off when the power is first turned on (step G5 in FIG. 12). ). As a result, when the calculator 10 is first used by the user after shipment, the post-factory inspection flag in the post-factory inspection flag area 22c is turned off. Further, the process of turning on the flag after the factory inspection (step S10) is executed only after the factory inspection process, and the factory inspection process (step S6) is not normally executed after the shipment. Therefore, after the calculator 10 is shipped and used by the user, the flag is not turned on after the factory inspection. Therefore, when the user replaces the battery after shipment, the flag is not turned on after the factory inspection (step S3: No), so that the CPU 21 does not execute the tax rate automatic setting process and waits for the input operation. Become. Subsequent processing is the same as described above.

Next, the key input waiting process according to the first control method in the present embodiment will be described with reference to the flowchart shown in FIG.

When the CPU 21 has a key input after the factory inspection process (step A1: Yes), the CPU 21 resets the APO counter described later (step A10), and then the power off key (for example, the [AC] key 11a and other identifications). It is determined whether the operation is a combination with the key of (step A6) or an operation (a dedicated key for turning off the power (not shown)). If the calculator 10 does not have a function of turning off the power by the power off key, after resetting the APO counter (step A10), the process of determining the operation of the power off key is omitted, and the process proceeds to step A7.

When it is determined that the operation is not the power off key operation (step A6: No), the CPU 21 determines whether the operation is the tax calculation mode switching key 11d ([GST + / TAX−]) (step A7). When it is determined that the operation is not the operation of the tax calculation mode switching key 11d (step A7: No), the CPU 21 executes a process (conventional process) according to the key input (step A9).

When the CPU 21 determines that the operation is the power off key operation (step A6: Yes), the CPU 21 refers to the post-factory inspection flag area 22c, and the post-factory inspection flag is set, and the factory inspection process has been executed (the flag is turned on after the factory inspection (first). 1 Information)) is indicated (step A11). When the flag is turned on after the factory inspection (step A11: ON), the CPU 21 disables the operation of the power off key (NOP) (step A12) and returns the process to the beginning of the key input waiting process (step A1). That is, the operation of the power off key is disabled (NOP) while the flag is on after the factory inspection. When the flag is off after the factory inspection (step A11: OFF), the CPU 21 executes a process (conventional process) according to the key input (step A9).

In step A11, the CPU 21 determines whether or not the factory inspection process has been executed by determining whether or not the factory inspection flag-on (first information) is indicated, but the present invention is limited to this. Instead, it may be determined whether or not the factory inspection process has been executed by determining whether or not the flag-off (second information) is not shown after the factory inspection. In this case, the CPU 21 determines that the factory inspection process has been executed when the post-factory inspection flag does not indicate off (second information), and indicates that the post-factory inspection flag is off (second information). In this case, it is determined that the factory inspection process has not been executed.

Therefore, after the factory inspection, the operation can be confirmed according to the key operation until the power is first turned off. For example, after the [AC] key 11a for terminating the factory inspection process is operated, as shown in FIG. 7A, the key input units 11 of "1", "2", "3", and "+" When each key is operated, the CPU 21 displays "123" on the main display unit, "1" on the number of steps 12a, and the symbol [+]. Even if the power off key is subsequently operated, the display on the main display does not change. During this period, since the tax calculation mode remains the tax-included calculation mode, the CPU 21 does not change the tax calculation mode symbol 12b and keeps displaying the symbol "GST +". The CPU 21 is the other key of the key input unit 11. When there is an operation for, the normal process (conventional process) corresponding to the key operation is executed.

On the other hand, when there is no key input (step A1: No), the CPU 21 subtracts the APO counter according to the passage of time (step A2). The APO counter is a counter for counting the time until the power is turned off by the APO function after the start time is when the execution of the factory inspection process is completed (step S7: Yes). A value corresponding to the time until the power is turned off is preset in the APO counter, and the value is subtracted with the passage of time. If the APO counter is not "0" (step A3: No), the CPU 21 returns the process to the beginning of the key input waiting process (step A1).

During this time, when it is detected that the tax calculation mode switching key 11d has been operated (step A7: Yes), the CPU 21 executes the switching key processing (step A8). As the switching key processing in the first control method, either the first switching key processing or the second switching key processing can be executed. Whether to execute the first switching key processing or the second switching key processing may be determined in advance, or in the mode setting processing to be executed separately, either one is selected according to the user operation. You may.

FIG. 5 is a flowchart showing the first switching key processing.

The CPU 21 refers to the post-factory inspection flag area 22c in response to the operation of the tax calculation mode switching key 11d, and the post-factory inspection flag indicates that the factory inspection process has been executed (flag on after factory inspection (first information)). It is determined whether or not (step B1). When the flag is turned on after the factory inspection (step B1: ON), the CPU 21 disables the operation of the tax calculation mode switching key 11d (NOP). That is, when the operation for changing the tax calculation mode is executed, the CPU 21 keeps the post-factory inspection flag in the post-factory inspection flag area 22c in the ON state and does not change the tax calculation mode.

In this case, as shown in FIG. 7A, the CPU 21 does not change the tax calculation mode symbol 12b in response to the key operation of the tax calculation mode switching key 11d ([GST + / TAX-]). Keep [GST +] displayed.

The calculator 10 is packed and shipped after the operation is confirmed after the factory inspection process. With the calculator 10 packed, the CPU 21 subtracts the APO counter according to the passage of time (step A2), and when the APO counter becomes "0" (step A3: Yes), the power is turned off by the APO function. For example, as shown in FIG. 7A, when the calculator 10 is left for 6 minutes and there is no key operation, the CPU 21 turns off the power by the APO function. In this case, the CPU 21 stores the post-factory inspection flag off (second information) in the post-factory inspection flag area 22c, which does not indicate that the factory inspection process has been executed (step A4). This second information is different from the first information.

The CPU 21 stores the flag-off after the factory inspection in the flag area 22c after the factory inspection, and then executes a normal power-off process (conventional off process) to stop the operation of the calculator 10 (step A5).

Therefore, in the first switching key processing of the first control method, even if the tax calculation mode switching key 11d is operated, the default is until the power is first turned off by the APO function after the factory inspection. The tax calculation mode (tax calculation mode) cannot be switched.

The calculator 10 after shipment is instructed to be activated by, for example, an operation on the [AC] key 11a by the user. The CPU 21 executes a normal power-on process in response to a key operation of the [AC] key 11a to activate the calculator 10. At this time, the tax calculation mode area 22m stores tax calculation mode data indicating the tax-included calculation mode set after the factory inspection.

Therefore, as shown in FIG. 7A, the CPU 21 causes the tax calculation mode symbol 12b to display the symbol [GST +] indicating the tax-included calculation mode when the power is first turned on by operating the [AC] key 11a. That is, it is possible to reliably set the default tax calculation mode set after the factory inspection. After being started, the CPU 21 executes the key input waiting process shown in FIG. Therefore, as shown in (A) of FIG. 7, when each of the "1", "2", "3", and "+" keys of the key input unit 11 is operated, the CPU 21 displays the main display in the same manner as described above. "123" is displayed in the section, "1" is displayed in the number of steps 12a, and the symbol [+] is displayed. Further, when the tax calculation mode switching key 11d is operated (step A7: Yes), the CPU 21 executes the first switching key process shown in FIG. In this case, when the power is turned off for the first time after the power inspection process, the flag off after the factory inspection is stored in the flag area 22c after the factory inspection (step B1: OFF), so that the CPU 21 operates the tax calculation mode switching key 11d. The tax calculation mode is switched accordingly (step B2). That is, as shown in FIG. 7A, when the tax calculation mode switching key 11d is operated in the tax-included calculation mode, the CPU 21 switches to the tax-excluded calculation mode and sets the tax calculation mode symbol 12b. , Change to the symbol [TAX-] indicating the tax-excluded calculation mode. After that, the CPU 21 switches the calculation mode between the tax-included calculation mode and the tax-excluded calculation mode each time the tax calculation mode switching key 11d is operated.

Next, the second switching key processing will be described. FIG. 6 is a flowchart showing the second switching key processing. Hereinafter, a process different from the above-described first switching key process will be described. FIG. 7B shows a key operation and a display example for explaining a specific processing content by the second switching key processing.

In the first switching key processing described above, the operation on the tax calculation mode switching key 11d is completely invalidated. In the second switching key processing, the operation for the tax calculation mode switching key 11d is valid only when it is determined that the operation for the tax calculation mode switching key 11d is different from the default operation.

As a method of operation different from the default operation for the tax calculation mode switching key 11d, for example, there is a long press operation for the tax calculation mode switching key 11d. The long press operation is an operation of continuing the pressed state for a predetermined arbitrary time or longer. The default operation is an operation of pressing for a shorter time than the "long press operation". The default operation will be described as "short press", normal press, etc. for convenience.

The CPU 21 refers to the post-factory inspection flag area 22c in response to the operation of the tax calculation mode switching key 11d, and the post-factory inspection flag indicates that the factory inspection process has been executed (flag on after factory inspection (first information)). It is determined whether or not (step C1). When the flag is turned on after the factory inspection (step C1: ON), the CPU 21 determines whether the tax calculation mode switching key 11d is being pressed and held (step C3). When it is determined that the long press operation has not been performed (step C3: normal press), the CPU 21 invalidates the operation of the tax calculation mode switching key 11d (NOP) in the same manner as the first switching key processing. On the other hand, when it is determined that the long press operation has been performed (step C3: long press), the CPU 21 switches the tax calculation mode according to the operation of the tax calculation mode switching key 11d (step C2). In this case, the CPU 21 stores the tax calculation mode data indicating the tax-excluded calculation mode in the tax calculation mode area 22m.

That is, as shown in FIG. 7B, the CPU 21 does not change the tax calculation mode symbol 12b in response to the key operation by normally pressing the tax calculation mode switching key 11d ([GST + / TAX-]). , The symbol [GST +] is displayed. Further, as shown in FIG. 7B, the CPU 21 uses the tax calculation mode symbol 12b as a symbol [TAX-] in response to a key operation by pressing and holding the tax calculation mode switching key 11d ([GST + / TAX-]). ] To display.

Therefore, in the second switching key processing of the first control method, the tax calculation mode switching key 11d is intended until the power is turned off by the APO function, that is, until the power is first turned off after the factory inspection. If it is operated without, the default tax calculation mode (tax calculation mode) cannot be switched. On the other hand, when the tax calculation mode switching key 11d is operated by an operation different from the default operation, the tax calculation mode is switched according to the operation for the tax calculation mode switching key 11d as an intentional operation. In this way, by enabling the tax calculation mode switching key 11d by a special operation after the factory inspection, it is possible to confirm the operation using the tax calculation mode switching key 11d.

When the tax calculation mode switching key 11d is used by a long press operation, the tax calculation mode is changed and the operation check is completed until the power is turned off by the APO function. By pressing and holding the button, the tax calculation mode switching key 11d is used to switch to the default tax calculation mode (tax-included calculation mode) at the time of shipment. In this case, the CPU 21 stores the tax calculation mode data indicating the tax-included calculation mode in the tax calculation mode area 22m.

Similar to the above, the calculator 10 is packed and shipped after the operation is confirmed after the factory inspection process. With the calculator 10 packed, the CPU 21 turns off the power by the APO function, and in the post-factory inspection flag area 22c, the post-factory inspection flag off (second information) that does not indicate that the factory inspection process has been executed. Remember (step A4). After that, the CPU 21 executes a normal power off process (conventional off process) to stop the operation of the calculator 10 (step A5).

Therefore, in the second switching key processing of the first control method, the tax calculation mode switching key 11d was operated differently from the default operation until the power was first turned off by the APO function after the factory inspection. Only in case, the default tax calculation mode (tax included calculation mode) is switched.

The calculator 10 after shipment is instructed to be activated by, for example, an operation on the [AC] key 11a by the user. The CPU 21 executes a normal power-on process in response to a key operation of the [AC] key 11a to activate the calculator 10. At this time, the tax calculation mode area 22m stores tax calculation mode data indicating the tax-included calculation mode set after the factory inspection. Therefore, when the user first turns on the calculator 10 after shipment, the calculator 10 is surely activated in the default tax calculation mode (tax-included calculation mode).

Hereinafter, as shown in FIG. 7B, the conventional processing according to the key operation or the operation of the tax calculation mode switching key 11d (normally pressed) can be performed in the same manner as when the first switching key processing described above is executed. The tax calculation mode is switched according to the situation.

According to the first control method in the present embodiment, the calculator 10 turns on the post-factory inspection flag after the factory inspection process (step S10), and only when the APO counter becomes "0" (step A3 :). Yes), after the factory inspection, the flag was turned off (step A4), and then the power was turned off (step A5). Further, while the flag is on after the factory inspection, the operation of the tax calculation mode switching key 11d is disabled (NOP) (step B1: ON → step B3). In addition, the calculator 10 disables the operation of the power off key while the flag is on after the factory inspection even if the operation of the power off key is not implemented in the first place or the operation of the power off key is implemented. (Step A6: Yes → Step A11: ON → Step A12).

Therefore, the calculator 10 is packed and shipped after the operation is confirmed after the factory inspection process, but even if an unintended key is touched before the shipment, the power is turned off first by the APO function. As long as you don't unintentionally touch the keys later, when the user unpacks and powers on, they can boot into the default calculation mode. For example, if the packing work is completed before the power is first turned off by the APO function, the key will not be unintentionally touched after the power is first turned off by the APO function.

In this way, the calculator 10 that executes the first control method of the present embodiment appropriately switches the flag after factory inspection on and off, and invalidates the operation of a specific key according to the state of the flag after factory inspection ( Compared to the one that is not controlled to be NOP), when the power is first turned on after the factory inspection shipment, it can be started in the default calculation mode more reliably.

In the above description, if the post-factory inspection flag is turned on after the factory inspection process (step S10), the operation is invalidated even if the power off key is operated (steps A6, A11, A12), but APO. The power may be turned off in response to the operation of the power off key before the power is turned off for the first time by the function. In this case, in the same manner as the power off by the APO function described above, the flag off after the factory inspection is stored in the flag area 22c after the factory inspection according to the operation of the first power off key, and then the normal power off process (conventional off). Process) is executed to stop the operation of the calculator 10 (step A5). According to such a process, after the factory inspection process, the flag is surely turned on after the factory inspection until the operation of the calculator 10 is stopped for the first time. Therefore, during that time, the tax calculation mode switching key 11d is operated. It is possible to prevent the tax calculation mode from switching.

Alternatively, when a predetermined threshold time shorter than the APO time elapses after the factory inspection process, the post-factory inspection flag area 22c stores the post-factory inspection flag off according to the determination that the threshold time has elapsed. At this time, it is not necessary to execute the normal power off processing (conventional off processing). After that, the APO counter becomes "0" and the APO function is activated, or the calculator 10 is operated by executing a normal power off process (conventional off process) in response to the operation of the first power off key. May be stopped. According to such a process, the flag is turned on after the factory inspection at least until the above threshold time elapses after the factory inspection process. Therefore, during that time, the tax calculation mode is set according to the operation of the tax calculation mode switching key 11d. It is possible to surely prevent switching.

Next, the second control method in this embodiment will be described. The process executed before the calculator 10 is shipped from the factory is assumed to be executed in the same manner as the flowchart shown in FIG. 3 described above, and detailed description thereof will be omitted.

Hereinafter, the key input waiting process according to the second control method in the present embodiment will be described with reference to the flowchart shown in FIG. FIG. 9 is a flowchart showing the APO process in the flowchart of FIG. FIG. 10 is a diagram showing a key operation and a display example for explaining a specific processing content in the second control method.

When the CPU 21 receives a key input after the factory inspection process (step D1: Yes), the CPU 21 resets the APO counter described later (step D8) and then determines whether the power off key is operated (step D6). When it is determined that the operation is the power off key operation (step D6: Yes), the same processing as that of the first control method is executed in steps D9 and D10, and thus the description thereof will be omitted. As in the first control method, when the calculator 10 is not provided with the function of turning off the power by the power off key, the process of determining the operation of the power off key is omitted after resetting the APO counter (step D8). The process proceeds to step D7.

Further, when it is determined that the operation is not the power off key operation (step D6: No), the CPU 21 executes a process (conventional process) according to the key input (step D7). That is, in the second control method, after the factory inspection, normal processing (conventional processing) corresponding to the key operation including the tax calculation mode switching key 11d is enabled until the power is first turned off. Therefore, it is possible to confirm the operation according to the key operation on the key input unit 11.

For example, as shown in FIG. 10, when the tax calculation mode switching key 11d is operated after the [AC] key 11a for ending the factory inspection process is operated, the CPU 21 taxes the tax calculation mode area 22m. The tax calculation mode is changed by storing the tax calculation mode data indicating the exclusion calculation mode. Further, the CPU 21 changes the tax calculation mode symbol 12b to "TAX-" indicating the tax-excluded calculation mode.

On the other hand, when there is no key input (step D1: No), the CPU 21 subtracts the APO counter according to the passage of time (step D2). If the APO counter is not "0" (step D3: No), the CPU 21 returns the process to the beginning of the key input waiting process (step D1).

The calculator 10 is packed and shipped after the operation is confirmed after the factory inspection process. With the calculator 10 packed, the CPU 21 subtracts the APO counter according to the passage of time (step D2), and when the APO counter becomes "0" (step D3: Yes), executes the APO process (step D4). ).

In the APO process, the CPU 21 refers to the post-factory inspection flag area 22c and determines whether the post-factory inspection flag indicates that the factory inspection process has been executed (flag-on after factory inspection (first information)). When the flag is turned on after the factory inspection (FIG. 9, step E1: ON), the CPU 21 executes the calculation mode setting process to set the tax calculation mode to the default calculation mode. That is, the CPU 21 stores the tax calculation mode data (GST +) indicating the tax-included calculation mode in the tax calculation mode area 22m (step E2). After that, the CPU 21 stores the post-factory inspection flag off (second information) that does not indicate that the factory inspection process has been executed in the post-factory inspection flag area 22c (step E3), and ends the APO process.

The CPU 21 stores the flag-off after the factory inspection in the flag area 22c after the factory inspection by the APO process, and then executes a normal power-off process (conventional off process) to stop the operation of the calculator 10 (step D5).

The calculator 10 after shipment is instructed to be activated by, for example, an operation on the [AC] key 11a by the user. The CPU 21 executes a normal power-on process in response to a key operation of the [AC] key 11a to activate the calculator 10. At this time, in the tax calculation mode area 22m, tax calculation mode data indicating the tax-included calculation mode set when the power is first turned off in the APO processing after the factory inspection is stored.

Therefore, as shown in FIG. 10, the CPU 21 causes the tax calculation mode symbol 12b to display the symbol [GST +] indicating the tax-included calculation mode when the power is first turned on by operating the [AC] key 11a. That is, it is possible to reliably set the default tax calculation mode set after the factory inspection. After being started, the CPU 21 executes the key input waiting process shown in FIG. Therefore, as shown in FIG. 8, when the "1", "2", "3", and "+" keys of the key input unit 11 are operated, the CPU 21 displays "1", "2", "3", and "+" on the main display unit in the same manner as described above. "123", "1" for the number of steps 12a, and the symbol [+] are displayed. Further, when the tax calculation mode switching key 11d is operated, the CPU 21 executes a process of switching the tax calculation mode by the conventional process. That is, as shown in FIG. 10, the CPU 21 switches to the tax-excluded calculation mode and changes the tax calculation mode symbol 12b to the symbol [TAX-] indicating the tax-excluded calculation mode. After that, the CPU 21 switches the calculation mode between the tax-included calculation mode and the tax-excluded calculation mode each time the tax calculation mode switching key 11d is operated.

Further, when the power of the CPU 21 is turned off after the second time after the factory inspection, that is, when the calculator 10 is shipped and the power is turned off by the APO process after the user starts using the CPU 21, the factory inspection is performed in the flag area 22c after the factory inspection. Since the post-flag off is stored (step E1: OFF), the tax calculation mode data set in the tax calculation mode area 22m is retained without executing the calculation mode setting process.

As described above, in the second control method, the normal processing corresponding to each key input including the tax calculation mode switching key 11d can be executed until the power is first turned off by the APO function after the factory inspection. Then, when the power is first turned off by the APO function (APO processing) after the factory inspection, the default tax calculation mode (tax-included calculation mode) is set by the calculation mode setting process. Therefore, even if the tax calculation mode switching key 11d is operated after the factory inspection, the calculator 10 can be shipped in a state of being set to the default tax calculation mode (tax-included calculation mode). Therefore, when the user first turns on the calculator 10 after shipment, the calculator 10 is surely activated in the default tax calculation mode (tax-included calculation mode).

According to the second control method in the present embodiment, the calculator 10 turns on the post-factory inspection flag after the factory inspection process (step S10), and only when the APO counter becomes "0" (step D3 :). Yes), the default calculation mode (calculation mode including tax) is set (step E2), the flag is turned off after the factory inspection (step E3), and then the power is turned off (step D5). In the calculator 10, the power off key operation is not implemented in the first place, or even if the power off key operation is implemented, the power off key operation is disabled while the flag is on after the factory inspection. (Step D6: Yes → Step D9: ON → Step D10).

Therefore, as with the first control method described above, the calculator 10 that executes the second control method of the present embodiment will more reliably be in the default calculation mode when the power is first turned on after the factory inspection shipment. Can be activated.

Next, the third control method in the present embodiment will be described. The process executed before the calculator 10 is shipped from the factory is assumed to be executed in the same manner as the flowchart shown in FIG. 3 described above, and detailed description thereof will be omitted. Hereinafter, the key input waiting process according to the third control method in the present embodiment will be described with reference to the flowchart shown in FIG. FIG. 12 is a flowchart showing the [AC] key processing according to the operation of the [AC] key 11a by the calculator 10 after shipment.

When the CPU 21 receives a key input after the factory inspection process (step F1: Yes), the CPU 21 resets the APO counter described later (step F6) and then determines whether the power off key is operated (step F7). When it is determined that the operation is the power off key (step F7: Yes), the same processing as that of the first control method is executed in steps F8 and F9, and thus the description thereof will be omitted. As in the first control method, when the calculator 10 is not provided with the function of turning off the power by the power off key, the process of determining the operation of the power off key is omitted after resetting the APO counter (step F6). The process proceeds to step F5.

Further, when it is determined that the operation is not the power off key operation (step F7: No), the CPU 21 executes a process (conventional process) according to the key input (step F5). That is, in the third control method, after the factory inspection, normal processing (conventional processing) corresponding to the key operation including the tax calculation mode switching key 11d is enabled. Therefore, it is possible to confirm the operation according to the key operation on the key input unit 11.

On the other hand, when there is no key input (step F1: No), the CPU 21 subtracts the APO counter according to the passage of time (step F2). If the APO counter is not "0", the CPU 21 executes processing according to the key input as described above (steps F1 and F5).

The calculator 10 is packed and shipped after the operation is confirmed after the factory inspection process. With the calculator 10 packed, the CPU 21 subtracts the APO counter with the passage of time (step F2), and when the APO counter becomes "0" (step F3: Yes), the conventional power-off process by the APO function is performed. Is executed (step F4).

In this way, in the third control method, after the factory inspection, the post-factory inspection flag area 22c is shipped with the post-factory inspection flag-on (first information) stored.

The calculator 10 after shipment is instructed to be activated by, for example, an operation on the [AC] key 11a by the user. The CPU 21 executes a normal power-on process in response to a key operation of the [AC] key 11a in the power-off state (FIG. 12, step G1: Yes) to activate the calculator 10.

The CPU 21 refers to the post-factory inspection flag area 22c after the power-on process, and determines whether the post-factory inspection flag indicates that the factory inspection process has been executed (flag-on after factory inspection (first information)). When the flag is turned on after the factory inspection (step G3: ON), the CPU 21 executes the calculation mode setting process to set the tax calculation mode to the default calculation mode. That is, the CPU 21 stores the tax calculation mode data (GST +) indicating the tax-included calculation mode in the tax calculation mode area 22m (step G4). After that, the CPU 21 stores the post-factory inspection flag off (second information) that does not indicate that the factory inspection process has been executed in the post-factory inspection flag area 22c (step G5), and the conventional [AC] key 11a AC processing is executed according to the operation for (step G6).

When the [AC] key 11a is operated when the power is not turned off (step G1: No), the CPU 21 executes an AC process according to the operation on the conventional [AC] key 11a (step G1: No). G6).

FIG. 10 is a diagram showing a key operation and a display example for explaining a specific processing content in the third control method. That is, in the third control method, the display is performed according to the key operation in the same manner as in the second control method described above. However, in the second control method, the calculation mode setting process is executed in the APO process to set the default tax calculation mode, whereas in the third control method, after the power is turned off by the APO function. At the first activation according to the [AC] key 11a of the above, the calculation mode setting process is executed to set the default tax calculation mode.

As described above, in the third control method, the normal processing corresponding to each key input including the tax calculation mode switching key 11d can be executed until the power is first turned off by the APO function after the factory inspection. Then, when the user first turns on the power after shipment, the default tax calculation mode (tax-included calculation mode) is set and activated. That is, even if the tax calculation mode switching key 11d is operated after the factory inspection and the tax calculation mode is changed, the tax calculation mode can be reliably activated by the default tax calculation mode (tax-included calculation mode).

According to the third control method in the present embodiment, the calculator 10 turns on the post-factory inspection flag after the factory inspection process (step S10), and only when the [AC] key 11a is operated while the power is on. (Step G1: Yes), the default calculation mode (calculation mode including tax) is set (step G4), and the flag is turned off after the factory inspection (step G5). In the calculator 10, the power off key operation is not implemented in the first place, or even if the power off key operation is implemented, the power off key operation is disabled while the flag is on after the factory inspection. (Step F7: Yes → Step F8: ON → Step F9).

Therefore, similarly to the first control method described above, the calculator 10 that executes the third control method of the present embodiment will be more reliably set in the default calculation mode when the power is first turned on after the factory inspection and shipment. Can be activated.

In the above embodiment, the factory inspection process has been described as a certain process performed before shipment from the factory, but not only the factory inspection process but also other predetermined processes may be targeted. Examples of various predetermined processes include setting initialization processing and restart processing for all electronic devices, and processing for setting a restricted mode in which some of the functions that can be executed by the device are restricted. .. In this case, the electronic device is set to the default processing mode according to the execution of the setting initialization process or the restart process of the electronic device, or the electronic device is set according to the execution of the process of setting the restriction mode of the electronic device. The device is set to restricted mode. After that, by executing any one of the first control method, the second control method, and the third control method described in the above embodiment, the power of the device is once turned off and then turned on. After that, various processing modes that have been set may be canceled.

Further, the method described in the embodiment, that is, each method such as the processing shown in the flowcharts of FIGS. 3 and 4, is a memory card (ROM card, RAM card, etc.), magnetic disk (ROM card, RAM card, etc.) It can be stored and distributed in a recording medium such as a flexible disk, a hard disk, etc.), an optical disk (CD-ROM, DVD, etc.), a semiconductor memory, or the like.
