In the function / key correspondence table, FIG.
As shown in (b), a function / key correspondence table in a character input state and a function / key correspondence table in a conversion result operation state are included. The character input state refers to a state in which a character string to be converted as a kana-kanji character is input as shown in FIG. 2A, and the conversion result operation state refers to FIGS.
As shown in (c) and (d), this indicates a state in which various operations can be performed on the result of the kana-kanji conversion.

Each function / key correspondence table includes an item indicating a function (“function” on the left side in the figure) and an item indicating the type of key to which the function indicated by the function item is assigned (the center in the figure). A “key”) and an item in which a description of the function is described (“function description” on the right side in the figure), and the items are associated with each other. When the same function is assigned to a plurality of keys, each key in the item “key” is shown separated by “,”. The item "function" stores a function number indicating a function, the item "key" stores a key code indicating a key, and the item "function description" stores a character code indicating a character constituting a description. I have.

In the character input state, as can be seen from the function / key correspondence table shown in FIG. 4A, for example, the “conversion” key is used for the kana-kanji conversion function, and the “→” key and “Ctrl + D” are used for the cursor right movement function. And a key are associated with each other.

In the conversion result operation state, as can be seen from the function / key correspondence table shown in FIG. 4B, for example, the "conversion" key is used for the next candidate function, and the "Shift + conversion" is used for the previous candidate function.
The key is the "→" key and "Ctrl"
+ D ”key.

Next, the state transition table will be described with reference to FIG. FIG. 5 is a diagram showing a configuration of a state transition table stored in the RAM of the information processing apparatus of FIG.

As shown in FIG. 5, the state transition table includes an item indicating a function (“function” on the left side in the figure) and an item indicating a state to which the state changes after execution of the function (“after execution” on the right side in the figure) State)). For example, as can be seen from FIG. 5, when the next candidate function is executed, the state changes to a conversion result editing state, and when the input character return function is executed, the state changes to a character input state.

Next, the function group table will be described with reference to FIG. FIG. 6 shows a RAM of the information processing apparatus of FIG.
FIG. 3 is a diagram showing a configuration of a function group table stored in the function group table.

As shown in FIG. 6, the function group table is composed of items indicating function groups (left-hand item “function group” in the figure) and functions indicating items (right-hand item “function” in the figure). A function group refers to a group of functions that are preferably assigned to the same key as a key for designating a function, and a function number indicating a function is stored in the item “function group.” For example, the cursor moves right. Has two functions, cursor right movement and attention phrase right movement. The function group of kana-kanji conversion / next candidate has two functions of kana-kanji conversion and next candidate.

Next, the operation in this embodiment will be described with reference to FIG.
This will be described with reference to FIG. FIG. 7 is a flowchart showing a processing procedure in character processing of the information processing apparatus of FIG.

Referring to FIG. 7, when a predetermined key of keyboard 5 is depressed (step S1), the function immediately before the key is depressed is determined (step S2). Depending on the type of the determined function, the functions corresponding to the pressed key include character input (step S3), kana-kanji conversion (step S4), next candidate (step S5), key definition change (step S6), and others. Any one of the functions (step S7) is executed.

In the character input (step S3), the code of the input character is stored in the input reading buffer of the RAM 3.

In the kana-kanji conversion (step S4), RA
The character indicated by the character code stored in the input reading buffer of M3 is converted into a kanji. For example, when the kana-kanji conversion function is executed in the state shown in FIG.
The kana-kanji conversion shown in (b) is performed. The state after the Kana-Kanji conversion is a conversion result operation state according to the state transition table shown in FIG.

In the next candidate (step S5), the next candidate for kana-kanji conversion is obtained for the noticed phrase of the conversion result obtained by kana-kanji conversion. For example, when the next candidate function is executed in the state shown in FIG. 2C, as shown in FIG. 2D, "secretary" is obtained as the next candidate of "kanji". The state after the execution of the next candidate function is a conversion result operation state according to the state transition table shown in FIG.

In the key definition change (step S6), a function operable in that situation is assigned to a key instructing the situation according to the situation immediately before instructing the key definition change.

In other functions (step S), for example, cursor movement is performed.

After one of the character input (step S3), kana-kanji conversion (step S4), next candidate (step S5), and other functions (step S7) is executed, the state of the state is changed according to the state transition table. A transition is made, but after execution of the key definition change (step S6), the state returns to the immediately preceding state without following the state transition table.

Next, the result obtained by executing each of the above functions is displayed on the CRT 9 (step S8). In this display process, the process of reading the data to be displayed, developing it into a pattern, and outputting it to the buffer 7 is repeated.

Next, the above-described function determination processing (step S
2) will be described in detail with reference to FIG. FIG.
8 is a flowchart showing a function determination process (step S2) of FIG.

In the function determination process (step S2), FIG.
As shown in (1), first, a process for acquiring a function / key correspondence table corresponding to a situation when a key is input is performed (step S11). In this process, a state number indicating the current state is extracted, and a function / key correspondence table corresponding to the state number is extracted from the function / key correspondence table group. For example,
When the "conversion" key is input in the state shown in FIG. 2A, a state number indicating a character input state is extracted, and a function / key correspondence table shown in FIG. 4A is obtained from this state number. .

After the function / key correspondence table is obtained, a process for obtaining the function corresponding to the input key is performed from the key input in step S1 and the obtained function / key correspondence table (step S1). S12). In this function acquisition processing, the acquired function / key correspondence table is searched using the key code of the input key, and the function number of the function corresponding to the key input by this search is obtained. For example,
In the example of step S11 described above, when the function / key correspondence table shown in FIG. 4A is searched using the key code of the “conversion” key as the key code of the input key, the kana-kanji conversion is obtained as the corresponding function. Can be

Next, the above-described key definition change processing (step S6) will be described in detail with reference to FIG. FIG. 9 is a flowchart showing the key definition changing process (step S6) of FIG. Note that, as an example of the description of this processing, an example in which a key for instructing a key definition change is input in the state shown in FIG. 2B will be described.

Referring to FIG. 9, first, a process of saving a state when a key for instructing a key definition change is input is performed (step S21). In this process, when the key definition change function is completed, the state number indicating the current state is stored in the state storage buffer of the RAM 3 so that the state can be returned to the state at the time of the key definition change instruction.

Next, a process for acquiring the function / key correspondence table in the state immediately before executing the key definition change is performed (step S22). In this process, the state number stored in the state storage buffer is extracted, and the function / key correspondence table corresponding to this state number is extracted from the function / key correspondence table group. For example, if a key for changing the key definition is input in the state shown in FIG. 2A, the state at the time of the key input is a conversion result operation state, and thus the function / key shown in FIG. A correspondence table is obtained.

After the function / key correspondence table is acquired, the contents of the function / key correspondence table are displayed on the screen of the CRT 9 (step S2).
3). For example, a display is performed in a form as shown in FIG. Since the function / key correspondence table stores only the functions that can be executed in the state when the key for instructing the key definition change is input, the operator checks the functions that can be executed in that state from the table. can do.

Next, a process for selecting a function for changing the key assignment from among the functions displayed on the screen of the CRT 9 is performed (step S24). The details of this process will be described later with reference to FIG.

After selecting the function, it is determined whether or not the selected function is a function for canceling the key definition changing function (step S25).

If it is determined that the operation is not canceled, a process for selecting a key to which the selected function is to be assigned is performed (step S26). Details of this processing will be described later.

When the key is selected, the state is restored (step S27). This state return is performed in step S2.
This is performed by setting the state indicated by the state number stored in the state storage buffer at 1 as the current state, and the state is returned to the state when the key definition change was instructed. After returning to the state, the process ends.

If it is determined that the operation has been canceled (step S2).
5), a state return (step S27) is performed.

Next, the above-described function selection processing (step S2)
4) will be described in detail with reference to FIG. FIG. 10 is a flowchart showing the function selection processing (step S24) of FIG.

Referring to FIG. 10, first, a function to be changed is selected by inputting a key assigned to the function (step S31). This input key is notified to the operator by the key assignment for the function displayed on the CRT 9 in the above-described step S21. For example, in the state where the table shown in FIG. 4B is displayed on the screen, when the function of moving the noticeable phrase right is designated, the “→” key or the “Ctrl + D” key is input.

Next, a function corresponding to the input key is obtained (step S32). The acquisition of this function is obtained by searching the function / key correspondence table acquired in step 22 described above. As a result of the search, if the input key does not exist in the function / key correspondence table, the function is not acquired.

Next, it is determined whether or not the function has been acquired (step S33). When the function is acquired,
Processing for confirming the function with the operator is performed (step S34). In this confirmation process, for example, a message for requesting the operator to continue the process is displayed on the CRT 9 together with the acquired function and the input key.

After the message is displayed, a determination is made as to whether the operator has permission to continue the process (step S36). If the operator permits the continuation of the process, the process ends. If the continuation of the process is not permitted, that is, if the continuation of the process is requested to stop, the process returns to step S31 again.

When no function has been acquired (step S
33) Then, a process for confirming cancellation of the key definition changing process to the operator is performed (step S35). In this confirmation processing, for example, a message for requesting the operator to permit the processing to be stopped is displayed on the CRT 9.

After the message is displayed, it is determined whether or not the operator has given permission to stop the process (step S37). If the operator permits the suspension of the process, the process ends. If the suspension of the process is not permitted, that is, if the continuation of the process is requested, the process returns to step S31 again.

Next, the above-described key setting processing (step S2)
6) will be described in detail with reference to FIG. FIG. 11 is a flowchart showing the key setting process (step S26) of FIG.

Referring to FIG. 11, first, a process for causing the operator to specify a key to be newly assigned to the function selected in step S24 is performed (step S41). In this process, the operator recognizes the key designated as the assigned key, and when the designated key is the same as the key to which the function has already been assigned, deletes the assignment for the function of the designated key. For example, “Ct” is displayed when the noticeable phrase shown in FIG.
When assigning the "rl + F" key, the operator presses the "Ctrl + F" key. In contrast,
In step S31, when deleting the assignment of the “Ctrl + D” key input for the attention phrase right movement shown in FIG. 4B, the operator inputs the “Ctrl + D” key, and the “Ctrl + D” key for the attention phrase right movement is deleted.
The "D" key assignment is deleted.

Next, the entered key is determined in step S2.
It is determined whether the key is already assigned to the function selected in step 4 (step S42). This determination is made by searching the function / key correspondence table acquired in step S22.

If the entered key is not a key that has already been assigned, the entered key is determined in step S24.
A double registration check is performed to determine whether or not a function other than the selected function has already been assigned (step S43). If the entered key is a key assigned to another function, double registration will be performed for that key, so the function must be uniquely determined by key input to indicate the function Can not be done. Therefore, when it is determined that the key is double-registered, the operator is notified to that effect, so that the operator is prompted to make a determination. ing. If the key assignment determined to be double registration is not deleted, it is determined that the processing cannot be continued, and a processing stop instruction is issued based on the result of the determination.

Next, it is determined whether or not a processing stop command has been issued (step S44). When the processing stop instruction has been issued, the processing ends.

When the processing stop command has not been issued, that is, when the input key is not a double registration key, the input key is registered (step S45). In this registration processing, the key input to the key item for the target function in the corresponding function / key correspondence table is added. For example, the movement of the noticeable phrase shown in FIG.
When assigning the “tl + F” key, the “Crtl + F” key is added to the already assigned keys, and “→”, “Crt”
There will be three keys, a "l + D" key and a "Crtl + F" key.

Next, a function group registration process for assigning an input key to each function of the group to which the function selected in step S24 belongs is performed (step S46), and the process ends.

If the input key is a key that has already been assigned (step S42), a process for deleting the input key assignment is performed on the function selected in step S24 (step S24). S4
7). Details of this processing will be described later with reference to FIG.

Next, it is determined whether or not the input key assignment has been deleted (step S48). If the input key assignment is not deleted, the process ends.

When the input key assignment is deleted,
For each function of the group to which the function selected in step S24 belongs, a function group key deletion process for deleting the input key assignment is performed (step S49), and the process ends. Details of the function group key deletion processing will be described later with reference to FIG.

Next, the double registration check process (step S43) will be described in detail with reference to FIG. FIG. 12 is a flowchart showing the double registration check process (step S43) of FIG.

Referring to FIG. 12, first, at step S2
The function / key correspondence table acquired in step 2 is searched, and whether the key input in step S41 has been already assigned to a function other than the function to be assigned, that is, whether or not the key has been registered twice. Is performed (step S51). For example, FIG.
When the "Crtl + S" key is assigned to the movement of the noticeable phrase shown in (1), since the "Crtl + S" key has already been assigned to the movement of the noticeable phrase to the left, the double registration is determined for the "Crtl + S" key.

Next, it is determined whether or not the above determination result indicates double registration (step S52). If not, the process ends.

In the case of double registration, a function other than the function to be assigned which is determined to be double registered is
A key deletion process for deleting the input key assignment is performed (step S53). In this process, for example, according to the above-described example, the “Crtl + S” key is deleted for the target phrase left shift. The details of this processing are described in FIG.
4 will be described later.

Next, it is determined whether or not the key assignment input in the key deletion process has been deleted (step S54). If the key is not deleted, it is determined that the process has been canceled, and the process ends.

When key deletion is performed, a function group key deletion for deleting an input key assignment for each function of a group to which a function other than the function to be assigned determined to be double registered belongs. Processing is performed (step S5
5), the process ends. Details of the function group key deletion processing will be described later with reference to FIG.

Next, the above-described function group key registration processing (step S46) will be described in detail with reference to FIG. FIG. 13 is a flowchart showing the function group key registration process (step S46) of FIG. In this description, an example will be described in which “Crtl + F” is assigned to the noticeable phrase right shift in the function / key correspondence table shown in FIG. 4B.

Referring to FIG. 13, first, processing for searching for a target function group is performed (step S6).
1). In this process, a function item in the function group table is searched to find a function group to which the target function belongs. For example, as the function group to which the attention phrase right movement belongs,
By searching the function group table shown in FIG. 6, a function group called right cursor movement is obtained.

Next, the above-described search result is determined (step S62). If there is no function group to which the target function belongs, the process ends.

When there is a function group to which the target function belongs, for each function belonging to the function group,
Processing for confirming with the operator whether or not to assign the key input in step S41, that is, whether or not to register is performed (step S63). In this process, the setting for obtaining the confirmation of the operator is performed by displaying the functions belonging to the searched function group.

Next, the result of the confirmation to the operator is determined (step S64). When the confirmation result indicates non-registration, the process ends.

When the result of the check indicates registration, a process for taking out the functions belonging to the searched function group one by one, excluding the functions assigned to the keys in step S45, is performed (step S65). For example, in the function / key correspondence table shown in FIG.
When the “rl + F” key is assigned, the function group to which the target phrase right shift belongs has two functions, cursor right movement and target phrase right shift, and the key has already been assigned in step S45 for the target phrase right shift. Therefore, in this processing, only the function of moving the cursor to the right is to be extracted.

Next, it is determined whether or not the above functions have been successfully extracted (step S66). When all the functions belonging to the searched function group have been extracted, the process ends.

When a function to be taken out remains in the searched function group, a process of acquiring a function / key correspondence table storing key assignments for the taken out function is performed (step S67). In this process,
The function / key correspondence table is obtained by searching all the function / key correspondence table function items stored in the key correspondence table group. For example, to move the cursor right,
When the function items of all the function / key correspondence tables stored in the key correspondence table group are searched, the function / key correspondence table shown in FIG. 4A is obtained.

Next, based on the acquired function / key correspondence table, a double registration check is performed to determine whether assigning the key input in step S41 to the function extracted in step S65 results in double registration. Is performed (step S68). Since the double registration check processing has already been described in detail in FIG. 12, the description thereof will be omitted.

After the double registration check processing, a judgment is made on the judgment result by the double registration check processing (step S69). When the determination result indicates stop, the process returns to step S65 again.

If the result of the determination indicates that the processing is to be continued, the function extracted in step S65 is added to step S41.
A process for assigning the key input in is performed (step S70). In this process, the key input in step S51 is added to the key item corresponding to the function extracted in step S65 in the function / key correspondence table acquired in step S67 and registered. For example, FIG.
When the "Crtl + F" key is assigned to the function / key correspondence table shown in "1", the keys are assigned to the rightward movement of the cursor, and the keys are "→", "Crtl + D" key, "Crtl + F"
There will be three keys, the key. After the registration of the key is completed, the process returns to step 65 again.

Next, the above-described key deletion processing (step S4)
7, step S53) will be described in detail with reference to FIG. FIG. 14 is a flowchart showing the key deletion processing (steps S47 and S53) of FIGS. 11 and 12.

Referring to FIG. 14, first, a process for asking the operator whether to delete the assignment of the target key from the target function is performed (step S71). In this process, a message requesting confirmation of the key deletion permission is displayed on the CRT 9 together with the target function and the key to be deleted, and the operator is prompted to input a key indicating permission or non-permission of the key deletion.

Next, it is determined whether or not the operator has permitted the key deletion (step S72). When the operator does not permit the key deletion, a process of deleting the target key assignment from the target function is performed (step S73). In this process, the target key is deleted from the key items corresponding to the functions in the function / key correspondence table to be deleted. For example, if the “Crtl + D” key is deleted for the target phrase right shift in the function / key correspondence table shown in FIG. 4B, only the “→” key exists as the key assigned to the target phrase right shift. become. After the end of the key deletion process, the process ends.

Next, details of the above-described function group key deletion processing (step S49) will be described with reference to FIG. FIG. 15 is a flowchart showing the function group key deletion processing (step S49) of FIG.

Referring to FIG. 15, first, a message for asking the operator whether or not to delete the assignment of all the functions assigned to the key for which the assignment has been deleted is sent to the operator. The information is displayed on the CRT 9 and the result of the confirmation by the operator is determined (step S81).

When the operator does not give an instruction to delete all the function assignments, a process is performed to search for a function group to which the function whose key assignment is to be deleted belongs (step S82). In this process, a function item in the function group table is searched to find a function group to which the target function belongs. For example, as the function group to which the noted phrase rightward movement belongs, a function group called cursor rightward movement is obtained by searching the function group table shown in FIG.

Next, the above-described search result is determined (step S83). If there is no function group to which the target function belongs, the process ends.

When there is a function group to which the target function belongs, for each function belonging to the function group,
Processing for confirming with the operator whether to delete the key assignment input in step S41 is performed (step S84). In this process, the setting for obtaining the confirmation of the operator is performed by displaying the functions belonging to the searched function group.

Next, the result of the confirmation to the operator is determined (step S85). When the confirmation result indicates non-deletion, the process ends.

When the confirmation result indicates deletion, the functions belonging to the searched function group are excluded, excluding the target function.
Processing for taking out one by one is performed (step S8)
6). For example, in the function / key correspondence table shown in FIG. 4B, when the assignment of the “Ctrl + D” key is deleted for the attention phrase right movement, the function group to which the attention phrase right movement belongs includes the cursor right movement and the attention phrase right movement. There are two functions of “move”, and “Ctrl + D” has already been performed for right movement of the target phrase.
Since the key assignment has been deleted, in this processing, only the function of moving the cursor to the right is taken out.

Next, it is determined whether or not the above-mentioned functions have been taken out (step S87). When all the functions belonging to the searched function group have been extracted, the process ends.

When a function to be taken out is taken out of the searched function group, a process of acquiring a function / key correspondence table storing key assignments for the taken out function is performed (step S88). In this process, the function / key correspondence table is obtained by searching all the function items of the function / key correspondence table stored in the function / key correspondence table group. For example, when searching for all the function / key correspondence table function items stored in the function / key correspondence table group in response to the cursor right movement, the function / key correspondence table shown in FIG.
A key correspondence table is obtained.

Next, based on the acquired function / key correspondence table, a key deletion process is performed to delete the target key assignment for the function extracted in step S86 (step S89). Since the key deletion process has already been described in detail in FIG. 14, the description thereof will be omitted.

After the key deletion processing, the processing returns to step S8.
Return to 6.

When the operator issues an instruction to delete all function assignments (step S81), a process is performed to extract the function / key correspondence tables one by one from the function / key correspondence table group (step S81). Step S90).

Next, it is determined whether or not all the function / key correspondence tables have been taken out (step S9).
1). When the retrieval of all the function / key correspondence tables is completed, the process ends.

On the other hand, when the extraction of all the function / key correspondence tables is not completed, it is determined whether or not the key to be deleted is registered in the extracted function / key correspondence table. (Step S92). This determination is made by searching for a key item in the extracted function / key correspondence table.

If no key to be deleted is registered in the extracted function / key correspondence table, the process returns to step S90.

When a key to be deleted is registered in the extracted function / key correspondence table, the key assignment input in step S41 is deleted based on the extracted function / key correspondence table (step S93). ), The process returns to step S90 again. For details on this key deletion process,
Since it has already been described, its description is omitted.

As described above, in this embodiment, when a function that can be executed in the same state is assigned to a key to which a function has already been assigned, the function that has already been assigned is set to be deleted. When a new function executable in the same state is assigned to a key for which a function has already been set, an operation for assigning the new function to the key can be easily performed.

Further, since the target key is selected from each key and the assignment relationship between the selected key and the function belonging to the selected function group is updated, the assignment relationship between the key and the function assigned to it is updated. Can be updated easily and easily.

In this embodiment, the function / key correspondence table existing for each state is used to determine whether two functions can be executed from the same state. Can be determined by other methods. For example, a function / key correspondence table that associates keys with functions,
A function that associates a function with a state in which the function can be executed.
By using two correspondence tables with the state correspondence table, it is possible to determine whether two functions can be executed in a certain state.

In this embodiment, in steps S45 and S70, the key input in step S41 is added and registered. However, the key input in step S31 is deleted from the target function. It is also possible to register.

Further, in this embodiment, the key is assigned to each function using the function / key correspondence table. However, the key may be assigned to the function group. For example, a function group / key correspondence table in which a function group is associated with a key for instructing execution of a function belonging to the function group is associated with a function and a state in which the function can be executed. Function
There is a method using a state correspondence table.

In this method, when a key is input, a function group corresponding to the input key is obtained based on a function group / key correspondence table, a function / state table for this function group is obtained, and the function / state table is searched. By determining the function corresponding to the state indicated by the current state, the function to be executed in the state at the time of key input can be determined. Also, when a key definition change is instructed, a function group / key correspondence table is displayed, and by selecting a key from the displayed keys, a function group to be changed is selected. can do. When a function group is selected, a function belonging to the function group and a description of the function are displayed using a function / state table existing for each function group. After displaying,
By inputting a key to be newly assigned, a key can be assigned to a target function group.

Further, a method without a function group is also possible. For example, by providing a function / state table in which a function executed by key input and a state in which the function can be executed are provided for each key, the same operation and effect as in the present embodiment can be obtained. In this method, the function / status table existing for each key becomes one function group. When a key is input, a function / state table corresponding to the input key is obtained, and a function corresponding to the state indicated by the current state is obtained by searching the function / state table. The function can be determined. Also, when a key definition change is instructed, the keys and the functions in the function / state correspondence table are displayed in association with each other, and a key selected from among the displayed keys is input to change the key definition. The target key can be selected. When a key is selected, a function executed by the key and a description of the function are displayed using a function / state table existing for each key. After the display, by inputting a key to be newly assigned, a target function / state table can be associated with the key.
