In the example of FIG. 3, the item counter “003” is displayed because the addition key is input three times from the start to the end of the calculation.

4 to 6 are diagrams for explaining a history information editing method according to the first embodiment. Here, a method for editing the history information shown in FIG. 3 will be described. FIGS. 4 to 6 show how the screen display states of the main display 158 and the sub-display 160 transition in the order of the state (a) to the state (q) according to the user operation. Specifically, in the left column and the right column of each state (a) to (q), the state of the screen of the main display 158 (hereinafter also referred to as “main screen”) and the screen of the sub display 160 (hereinafter referred to as “main screen”). , Also referred to as “sub-screen”).

Referring to FIG. 4, state (a) shows a main screen and a sub screen in a state where memo information is input. When the up cursor key 50 or the down cursor key 60 is input from the state (a), the arithmetic processing device 10 is a mode for confirming (viewing) history information displayed on the sub screen from the normal input processing mode. Migrate to In the present embodiment, the arithmetic processing unit 10 performs more specific editing after shifting to the “CHECK” mode (hereinafter also referred to as “confirmation mode”) for confirming history information. Move to edit mode. The edit mode includes a “CORRECT” mode for correcting history information (hereinafter also referred to as “correction mode”), a “DELETE” mode for deleting history information (hereinafter also referred to as “delete mode”), In addition, an “INSERT” mode (hereinafter also referred to as “insertion mode”) for inserting new information into the current history information is included.

When the up cursor key 50 is input a plurality of times from the state (a), the state transitions to the state (b). In the state (b), the step number “005” is the last line of the sub screen. A character string 1102 indicating that the arithmetic processing device 10 is in the confirmation mode state is displayed on the sub-screen of the state (b). On the main screen in the state (b), a symbol “---” indicating that the editing is impossible (because it is in the confirmation mode state) is displayed. In the present embodiment, it is assumed that history information for five lines is displayed on the sub-screen.

Subsequently, when the “CORRECT” key is input in the state (b), the state transitions to the state (c). In addition to the character string 1102, the sub screen further displays a character string 1104 indicating the correction mode state. That is, in the correction mode, the character string 1102 and the character string 1104 are displayed on the sub screen.

Here, in the present embodiment, the partial history information displayed on the last line of the sub screen is designated as an object to be edited (here, modified). Therefore, the user uses the up cursor key 50 and the down cursor key 60 to change the screen so that the partial history information to be corrected is displayed on the last line of the sub screen.

Although the details will be described later, the arithmetic processing unit 10 is configured to determine whether or not the partial history information designated as the correction target can be corrected based on a predetermined rule. If the arithmetic processing unit 10 determines that the correction is possible, the arithmetic processing unit 10 displays a numerical value (a numerical value indicated by the partial history information) based on the partial history information in the last line (step number “005”) of the sub-screen on the main screen. For example, as in the main screen in the state (c), the numerical value “400′000” included in the partial history information on the last line of the sub screen is displayed. On the other hand, if the arithmetic processing unit 10 determines that the correction is impossible, the arithmetic processing unit 10 displays a symbol “---” indicating that the correction cannot be made on the main screen. Thereby, the user can grasp whether or not the specified partial history information can be corrected.

When the “5”, “0”, “00”, and “00” keys are sequentially input in the state (c), the state transitions to the state (d). In the state (d), the input numerical value “500′000” is displayed on the main screen. Subsequently, when the “CORRECT” key is input in the state (d), the state transitions to the state (e).

Referring to the sub-screen of the state (e), the numerical value of the step number “005” is corrected from “400′000” to “500′000”. In addition, when the “CORRECT” key is re-input and the correction mode is ended, the mode automatically returns to the confirmation mode. Therefore, the character string 1104 is not displayed on the sub screen. In addition, the symbol “---” indicating that editing is not possible is displayed on the main screen in the state (e).

When the down cursor key 60 is input twice in the state (e), the state transitions to the state (f). In the sub-screen in the state (f), the total result at the step number “007” is corrected from “1′000′000” to “1′100′000” with the numerical value correction at the step number “005”. It is shown that.

In state (f), when the lower cursor key 60 is input four times and the “CORRECT” key is further input, the state transitions to the state (g) of FIG. Referring to FIG. 5, in state (g), partial history information of step number “010” is designated as a correction target (see sub-screen). Since the partial history information can be corrected, a numerical value “600′000” based on the partial history information is displayed on the main screen.

In state (g), when an addition key is input, transition is made to state (h). In the state (h), the operator of the step number “010” is corrected from “−” to “+” (refer to the sub screen). In addition, when the addition key as an operator key is input and the correction mode is ended, the mode automatically returns to the confirmation mode, and thus the character string 1104 is not displayed on the sub screen. In addition, the symbol “---” indicating that editing is not possible is displayed on the main screen in the state (h).

In state (h), when the lower cursor key 60 is input three times, the state (i) is changed. In the state (i), the total result shown in the step number “013” is corrected from “1′200′000” to “2′400′000” with the operator correction in the step number “010”. (See sub screen). Further, the item counter of the step number “012” is also corrected from “002” to “004”.

Next, a history information deletion method using the “DELETE” key will be described. When the “DELETE” key is input in the state (i), the state transitions to the state (j). A character string 1106 indicating that the arithmetic processing unit 10 is in the delete mode state is further displayed on the sub-screen of the state (j). That is, in the delete mode, the character string 1102 and the character string 1106 are displayed on the sub screen.

In state (j), the partial history information of step number “013” is designated as a deletion target (see sub screen). Here, the arithmetic processing unit 10 determines that the partial history information cannot be deleted based on a predetermined rule. Therefore, a symbol “---” indicating that editing (in this case, deletion) is impossible is displayed on the main screen.

In state (j), when the up cursor key 50 is input five times, the state transitions to state (k). In the state (k), the partial history information of the step number “008” is designated as a deletion target (see sub screen). In addition, since the partial history information can be deleted, a numerical value “500′000” based on the partial history information is displayed on the main screen.

When the “DELETE” key is input in the state (k), the partial history information of the step number “008” is deleted, and the state (l) is transitioned to. On the sub-screen in the state (l), the partial history information of the step number “009” before deletion is moved up and displayed at the step number “008”. In addition, when the “DELETE” key is input again and the deletion mode is ended, the mode automatically returns to the confirmation mode, and thus the character string 1106 is not displayed on the sub screen. The symbol “---” is displayed on the main screen in the state (l).

Next, an insertion method for adding new information to the history information using the “INSERT” key will be described. When the down cursor key 60 is input twice in the state (l), the state transitions to the state (m) in FIG.

Referring to FIG. 6, when the “INSERT” key is input in the state (m), the state transitions to the state (n). In the state (n), a blank line is provided between the line corresponding to the step number “010” on the sub-screen and the line corresponding to the step number “009” one level higher. In addition, in addition to the character string 1102, a character string 1108 indicating the state of the insertion mode is further displayed on the sub-screen of the state (n). That is, in the insertion mode, the character string 1102 and the character string 1108 are displayed on the sub screen.

In the state (n), a portion between the partial history information of the step number “009” and the partial history information of the step number “010” (that is, a blank line) is designated as an insertion position of new partial history information. The arithmetic processing unit 10 determines that new partial history information can be inserted at the insertion position based on a predetermined rule. In this case, new partial history information has not yet been inserted in the blank line. Therefore, the numerical value “0” is displayed on the main screen.

Since the character string 1108 is displayed in the vicinity of the blank line, the user can easily grasp the insertion position of new partial history information. Note that the user may be notified of the insertion position of new partial history information as in the example of FIG.

FIG. 7 is a diagram for explaining an example of an object indicating the insertion position of the partial history information according to the first embodiment. Referring to FIG. 7, in addition to the character string 1108, an arrow object 1110 is further displayed in the vicinity of the character string 1108 on the sub-screen of the pattern (a). In addition to the character string 1108, an arrow object 1112 is further displayed on the sub-screen of the pattern (b). According to the patterns (a) and (b), the user can more easily grasp the insertion position of new partial history information.

In the state (n) in FIG. 6 and the patterns (a) and (b) in FIG. 7, the configuration in which a blank line is provided to indicate the insertion position of new partial history information has been described. Not limited to. For example, without providing a blank line, the arrow object 1110 of the pattern (a) in FIG. 7 is changed from the partial history information (600'000. +) Of the step number “009” and the partial history information of the step number “010” ( 700'000. +) (That is, between the 4th and 5th lines) and displayed, and may indicate a position where new partial history information is inserted.

Referring to FIG. 6 again, when the “8”, “0”, “00”, and “00” keys are sequentially input in state (n), the state transitions to state (о). In the state (о), the input numerical value “800′000” is displayed on the main screen. Subsequently, when an addition key is input in the state (о), the state transitions to the state (p).

On the sub-screen of the state (p), the partial history information of the step number “009” before insertion (corresponding to “600′00. +”) And the partial history information of the step number “010” before insertion (“700”). “800'000. +” Is inserted as new partial history information in a blank line between “00. +” and the corresponding partial history information of step number “010” before insertion. Is displayed at step number “011.” Since the addition mode is entered and the insertion mode is terminated, the mode automatically returns to the confirmation mode, and thus the character string 1108 is erased. The symbol “---” is displayed on the main screen in the state (p).

In state (p), when the lower cursor key 60 is input twice, the state (q) is transitioned to. With reference to the state (q) sub-screen, the total result indicated by the step number “013” is corrected to “2′700′000” with the insertion.

FIG. 8 is a diagram for explaining a rule for history editing according to the first embodiment. The rule table shown in FIG. 8 includes an item “calculation type”, an item “input key”, an item “history”, an item “CORRECT”, an item “INSERT”, and an item “DELETE”.

An example of the calculation type “clear processing” will be described. When a clear key is input as an input key, clear processing is performed, and “0 * C” is displayed on the sub screen as partial history information. When the partial history information is designated as an editing target (that is, when the step number of the partial history information is located in the last line of the sub screen), all correction, deletion, and insertion are in rule NG1. Prohibited on the basis. Specifically, modification and deletion of “0 * C” itself is prohibited, and insertion of new partial history information in a line above “0 * C” is also prohibited. The rule NG1 is a rule that prohibits editing of partial history information including a clear result, a total (total result), a subtotal (subtotal result), a calculation result, and a memory call.

An example of the calculation type “addition / subtraction” will be described. When partial history information including an item counter is designated as an editing target, correction and deletion are prohibited based on the rule NG4. The rule NG4 is a rule that prohibits editing of the count number.

An example of the calculation type “multiplication / division” will be described. When partial history information indicating “6 =” is designated as an editing target, deletion is prohibited based on rule NG6. The rule NG6 is a rule that prohibits editing of partial history information corresponding to a portion other than the head of the calculation so that the calculation cannot be established.

An example of the calculation type “TAX calculation” will be described. When the numerical value “100” is input and the “TAX +” key is input, the input numerical value “100” is displayed on the sub screen as the first partial history information, and the tax rate is set as the second partial history information. The value “8 TAX” is displayed, and the tax-included calculation result “108 TAX +” is displayed as the third partial history information. When the second partial history information is designated as an editing target, all corrections, deletions, and insertions are prohibited based on the rule NG2. The rule NG2 is a rule that prohibits editing of the set value. Further, when the first partial history information is designated as an editing target, deletion is prohibited based on the rule NG5. The rule NG5 is a rule that prohibits editing of partial history information corresponding to the head of the calculation so that the calculation does not hold.

An example of the calculation type “COST / SELL / MARGIN calculation” will be described. When the numerical value “100” is input and the “COST” key is input, the input numerical value “100 COST” is displayed on the sub screen as the first partial history information. When the numerical value “200” is input and the “SELL” key is input, “200 SELL” is displayed as the second partial history information on the sub screen. Also, “50 MGN%” is displayed as the third partial history information on the sub-screen. When the second partial history information is designated as an editing target, insertion is prohibited based on the rule NG3, and deletion is prohibited based on the rule NG6. The rule NG3 is a rule that prohibits editing that changes a predetermined series of calculation processes.

An example of the calculation type “% calculation” will be described. When the numerical value “200” is input and the “×” key is input, “200 ×” is displayed as the first partial history information on the sub screen. When the numerical value “25” is input and the “%” key is input, “25%” is displayed as the second partial history information on the sub screen. In addition, “50 *” is displayed as the third partial history information on the sub-screen. When the first partial history information is designated as an editing target, the first partial history information can be deleted, but the second and third partial history information are also based on the rule OK1. It is deleted at once. The rule OK1 is a rule that deletes the entire series of calculation processes all at once. If the “+” key is entered after “% calculation”, it will be “extra calculation”, and the sub screen will display “50+” as the fourth history information and “250 *” as the fifth history information. Is displayed.

In the above description, the rule OK1 can be used instead of the rule NG5. For example, in the calculation type “TAX calculation”, when the first partial history information (corresponding to the input numerical value “100”) is designated as an editing target, the first partial history information is included based on the rule OK1. The second partial history information (corresponding to “8 TAX”) and the third partial history information (“108 TAX +”) may be deleted.

Specifically, the display control unit 208 displays a main screen and a sub screen as shown in FIGS. 4 to 6 based on various instruction inputs received by the input unit 202. Specifically, the display control unit 208 displays the calculation information received by the input unit 202 (for example, input numerical values) and the calculation result of the calculation unit 204 (for example, subtotal results, total results, etc.) on the main display 158. And the history information of the calculation result is controlled to be displayed on the sub-display 160.

Also, the display control unit 208 changes the display content of the main display 158 based on the determination result of the permission determination unit 206. Specifically, the display control unit 208 causes the main display 158 to display a numerical value based on the designated partial history information when editing of the partial history information designated as the editing target is permitted by the permission determining unit 206. . When editing of the specified partial history information is not permitted by the permission determining unit 206, the display control unit 208 causes the main display 158 to display an object (for example, the symbol “---”) indicating prohibition of the editing. In addition, when the insertion mode is selected, the display control unit 208 causes the sub display 160 to display an object (for example, arrows 1110, 1112, etc.) indicating the insertion position of new partial history information.

The editing execution unit 210 edits the history information of the calculation result of the calculation unit 204 using at least one editing mode. Specifically, the editing execution unit 210 executes the editing when history information editing using the selected editing mode is permitted. More specifically, when the modification (or deletion) of the specified partial history information is permitted by the permission determining unit 206, the editing execution unit 210 performs the specified portion according to the correction instruction (or deletion instruction) from the user. Correct (or delete) history information. When the insertion of new partial history information is permitted between the designated partial history information and other partial history information, the editing execution unit 210 displays the new partial history information according to the insertion instruction from the user. insert. Note that the editing execution unit 210 stores the edited history information in the history information storage unit 212. In addition, the display control unit 208 causes the sub display 160 to display history information edited by the editing execution unit 210.

<Processing procedure>
FIG. 10 is a flowchart showing an example of the processing procedure of arithmetic processing unit 10 according to the first embodiment. The following steps of the arithmetic processing unit 10 are realized by the processor 152 executing a program stored in the memory 154.

Referring to FIG. 10, the processor 152 determines whether or not a key input has been accepted via the keyboard 156 (step S10). If no key input has been received (NO in step S10), processor 152 repeats the process in step S10. When a key input is accepted (YES in step S10), processor 152 determines whether or not the key input is an “INSERT” key input (step S12).

If it is not an input of the “INSERT” key (NO in step S12), the processor 152 executes a process of step S14 described later. On the other hand, when the input is “INSERT” key (YES in step S12), processor 152 switches the operation mode of arithmetic processing unit 10 to the insertion mode (step S20). Typically, the processor 152 switches from a mode other than the insertion mode (normal input processing mode, confirmation mode, deletion mode, or correction mode) to the insertion mode.

Subsequently, the processor 152 determines whether or not the insertion processing for the partial history information corresponding to the designated line on the sub screen is prohibited based on a predetermined rule (step S22). If the insertion process is prohibited (YES in step S22), the processor 152 displays a predetermined object (for example, the symbol “---”) on the main display 158 (step S36), and performs the process. finish.

If the insertion process is not prohibited (NO in step S22), the processor 152 adds a blank line to the sub-display 160 (step S24) and ends the process. At this time, the processor 152 may display objects (for example, arrow objects 1110 and 1112) indicating the insertion position of new partial history information on the sub display 160.

Next, processing from step S14 will be described. The processor 152 determines whether or not the key input received in step S10 is input of the “CORRECT” key (step S14). If it is not an input of the “CORRECT” key (NO in step S14), the processor 152 executes a process of step S16 described later. On the other hand, when the “CORRECT” key is input (YES in step S14), the processor 152 switches the operation mode of the arithmetic processing unit 10 to the correction mode (step S26). Typically, the processor 152 switches from a mode other than the correction mode (for example, a normal input processing mode, a confirmation mode, a deletion mode, or an insertion mode) to the correction mode.

Subsequently, the processor 152 determines whether or not correction processing for partial history information corresponding to a designated line on the sub-screen is prohibited based on a predetermined rule (step S28). If the correction process is prohibited (YES in step S28), the processor 152 displays a predetermined object on the main display 158 (step S36) and ends the process.

If the correction process is not prohibited (NO in step S28), the processor 152 displays the numerical value included in the partial history information on the main display 158 (step S34), and ends the process.

Next, processing from step S16 will be described. The processor 152 determines whether or not the key input received in step S10 is an input of the “DELETE” key (step S16). If it is not the input of the “DELETE” key (NO in step S16), the processor 152 executes a process corresponding to the key input (step S18) and ends the process. On the other hand, when the “DELETE” key is input (YES in step S16), the processor 152 switches the operation mode of the arithmetic processing unit 10 to the deletion mode (step S30). Typically, the processor 152 switches from a mode other than the deletion mode (for example, a normal input processing mode, a confirmation mode, a correction mode, or an insertion mode) to the deletion mode.

Subsequently, the processor 152 determines whether or not the deletion process for the partial history information corresponding to the designated line on the sub-screen is prohibited based on a predetermined rule (step S32). If the deletion process is prohibited (YES in step S32), the processor 152 displays a predetermined object on the main display 158 (step S36) and ends the process. If the deletion process is not prohibited (NO in step S32), the processor 152 displays the numerical value included in the partial history information on the main display 158 (step S34), and ends the process.

<Advantages>
According to the first embodiment, it is possible to check the input calculation information and calculation results displayed on the main screen while checking the history information displayed on the sub-screen. In addition, when editing history information, it is possible to notify the user in advance whether modification and deletion of a line designated as an edit target and insertion into a designated line are permitted or prohibited. For this reason, it is possible to prevent an operation for editing history information that does not match the consistency of calculation. In addition, since erroneous history editing is not executed, the operation of the arithmetic processing unit 10 is also stabilized.

[Embodiment 2]
In the second embodiment, a description will be given of a configuration in which history information is deleted in chronological order when history information becomes excessive. Specifically, when it is determined that the history information has reached a predetermined amount or more, arithmetic processing device 10 according to the second embodiment deletes the history information from the oldest.

FIG. 11 and FIG. 12 are diagrams for explaining a history information deletion method according to the second embodiment. Note that states (a) to (d) in FIGS. 11 and 12 show the screen states of the sub screens. A state (a) in FIG. 11 shows a state before the history information is deleted.

The history information is divided into a plurality of groups for each piece of partial history information including information indicating that a predetermined key input has been performed. The predetermined keys are, for example, a total key and a clear key. In the state (a) sub-screen, the partial history information of step number “011” includes identification information (input code) indicating that the total key has been input. In order to notify the user that the total key has been input, this identification information is displayed as an object 1202, for example. Further, since the partial history information of step number “023” and step number “030” also includes the identification information, the object 1202 is displayed. The partial history information of step number “026” includes identification information indicating that the clear key has been input. This identification information is displayed as an object 1206.

Here, the object 1204 is displayed at the step number “013”. Here, the object 1204 is the same as the object 1202. However, the object 1204 is an object displayed when the equal key is input at the step number “012”, and is not an object displayed when the total key is input. That is, the partial history information of step number “013” does not include identification information indicating that the total key has been input. Note that the object 1202 and the object 1204 may be displayed with different symbols.

As described above, the history information in the state (a) includes the group X1 including the partial history information from the step numbers “001” to “011” and the group X2 including the partial history information from the step numbers “012” to “023”.

To do. The history information in the state (c) in FIG. 12 is obtained by deleting the group X1 from the history information in the state (b) in FIG. The arithmetic processing unit 10 adds the total result in the calculation process included in the group X1 in the state (b) to the group X2 in the state (b) to generate the group X1 in the state (c). Specifically, the group X1 in the state (c) is obtained by adding partial history information from step numbers “001” to “003” to the group X2 in the state (b).

The partial history information of step number “001” and the partial history information of step number “002” in state (c) are the partial history information of step number “015” and the portion of step number “016” in state (b), respectively. Corresponds to history information. The partial history information of step number “003” in the state (c) includes deletion notification information. The group X2 in the state (c) corresponds to the group X3 in the state (b).

Subsequently, when the number of pieces of partial history information included in the history information exceeds a predetermined number in the state (c), the arithmetic processing device 10 deletes the group X1 including the oldest partial history information. The history information in the state (d) is obtained by deleting the group X1 from the history information in the state (c). The arithmetic processing unit 10 adds the clear result included in the group X1 in the state (c) to the group X2 in the state (c) to generate the group X1 in the state (d). The group X1 in the state (d) is obtained by adding partial history information from step numbers “001” to “003” to the group X2 in the state (c).

The partial history information of step number “001” in the state (d) includes information indicating that the number of item counters is zero. The partial history information with the step number “002” corresponds to the partial history information with the step number “006” in the state (c). The partial history information of the step number “003” in the state (d) includes deletion notification information.

FIG. 13 is a screen transition diagram for explaining the history information deletion method according to the second embodiment. FIG. 13 shows a state in which the screen display states of the main display 158 and the sub-display 160 transition from state (a) to state (d) in accordance with a user operation. Specifically, the left column and the right column of the states (a) to (d) respectively indicate the state of the main screen and the state of the sub screen.

Referring to FIG. 13, state (a) indicates a state in which “1”, “+”, “2”, and “+” are input after power is turned on. On the main screen in the state (a), the numerical value “3” as the addition result is displayed. When an input for sequentially adding numerical values “3” to “298” is executed from the state (a), the state transitions to the state (b). On the main screen in the state (b), “44′551”, which is the result of sequentially adding 1 to 298, is displayed. Further, the sub-screen shows that the step number has reached 299.

When the “1” key and the “x” key are input from the state (b), the state (c) is transitioned to. A numerical value “1” is displayed on the main screen in the state (c), and the sub screen indicates that the step number has reached 300.

When the “2”, “9”, “9”, “+” key is input from the state (c), the state transitions to the state (d). On the main screen in the state (d), the calculation result “44′850” obtained by adding the numerical value “299” to the addition result “44′551” at the time of the step number “299” is displayed. Here, in the example of FIG. 13, since neither the total key nor the clear key is input between step numbers “001” to “300”, the history information is not divided into a plurality of groups. That is, the partial history information of step numbers “001” to “300” is included in one group.

The arithmetic processing unit 10 determines that the step number has exceeded 300, and displays intermediate results from step numbers “001” to “300” in the state (c) on the sub-screen in the state (d). Specifically, an intermediate result of addition / subtraction is displayed at step number “001” in the sub-screen of state (d), an intermediate result of multiplication / division is displayed at step number “002”, and step number “003”.

X4). When the number of partial history information exceeds a predetermined number, the editing execution unit 210 deletes a plurality of groups in order from the group including the partial history information with the oldest history.

The display control unit 208 causes the sub-display 160 to display a calculation result based on the partial history information included in the deleted group. Specifically, the display control unit 208 causes the sub-display 160 to display the total result of the calculation based on the partial history information included in the deleted group and the intermediate result of the calculation.

<Advantages>
According to the second embodiment, when the number of histories becomes a predetermined number or more, the oldest histories are deleted in order. For this reason, the user does not need to be aware of the data capacity and the limit of the number of steps, which improves convenience. In addition, history information is deleted in units of groups divided based on the total process and the clear process of addition / subtraction. Furthermore, instead of deleting all partial history information included in the group to be deleted, necessary information such as total results (and intermediate results) is left and displayed on the sub-screen. Therefore, it is possible to achieve consistency when checking the calculation result, and the user is not confused. In addition, since the total result and the intermediate result in the deleted history are left, recalculation becomes easy.
