  Hereinafter, an embodiment in which an electronic apparatus according to the present invention is applied to an electronic dictionary will be described in detail with reference to the drawings.

[Appearance configuration]
FIG. 1 is a plan view of the electronic dictionary 1.
As shown in this figure, the electronic dictionary 1 includes a main display 10, a sub display 11, and a key group 2.

  The main display 10 and the sub-display 11 are parts for displaying various data such as characters and symbols according to the operation of the key group 2 by the user, and are configured by an LCD (Liquid Crystal Display), an ELD (Electronic Luminescence Display), or the like. ing. The main display 10 and the sub display 11 in the present embodiment are formed integrally with a so-called touch panel 110 (see FIG. 2) and can accept operations such as handwriting input.

  The key group 2 has various keys that receive operations for operating the electronic dictionary 1 from the user. Specifically, the key group 2 includes a translation / decision key 2b, a character key 2c, a dictionary selection key 2d, a cursor key 2e, a shift key 2f, a return key 2g, and the like.

  The translation / decision key 2b is a key used for executing a search, determining a headword, and the like. The character key 2c is a key used for inputting characters by the user, and includes “A” to “Z” keys in the present embodiment. The dictionary selection key 2d is a key used for selecting a dictionary database 820, which will be described later (see FIG. 2).

  The cursor key 2e is a key used for the reverse display position in the screen, that is, the movement of the cursor position. In the present embodiment, the up / down / left / right directions can be designated. The shift key 2f is a key used when a Japanese word is set as a search target. The return key 2g is a key used when returning to the previously displayed screen.

[Internal configuration]
Next, the internal structure of the electronic dictionary 1 will be described. FIG. 2 is a block diagram showing an internal configuration of the electronic dictionary 1.

  As shown in this figure, the electronic dictionary 1 includes a display unit 40, an input unit 30, a CPU (Central Processing Unit) 20, a flash ROM (Read Only Memory) 80, and a RAM (Random Access Memory) 90, each of which is a bus. 100 are connected to each other so that data communication is possible.

  The display unit 40 includes the main display 10 and the sub display 11 described above, and displays various types of information on the main display 10 and the sub display 11 based on a display signal input from the CPU 20.

  The input unit 30 includes the key group 2 and the touch panel 110 described above, and outputs a signal corresponding to the pressed key or the position of the touch panel 110 to the CPU 20.

  The CPU 20 executes processing based on a predetermined program in accordance with an input instruction, performs an instruction to each function unit, data transfer, and the like, and comprehensively controls the electronic dictionary 1. Specifically, the CPU 20 reads various programs stored in the flash ROM 80 according to an operation signal or the like input from the input unit 30, and executes processing according to the program. Then, the CPU 20 stores the processing result in the RAM 90 and causes the display unit 40 to output the processing result as appropriate.

  The flash ROM 80 is a memory that stores programs and data for realizing various functions of the electronic dictionary 1. In the present embodiment, the flash ROM 80 stores an information display program 81 according to the present invention, a dictionary database group 82, a handwritten image table 84, a memorized card database group 83, and the like.

  The information display program 81 is a program for causing the CPU 20 to execute a later-described memorization card process (see FIGS. 6 to 9). Note that the information display program according to the present embodiment causes the CPU 20 to execute character recognition processing of a handwritten image input from the touch panel 110.

  The dictionary database group 82 includes a plurality of dictionary databases 820,..., And in the present embodiment, includes an English-Japanese dictionary database 820a. In these dictionary databases 820,..., As shown in an example in FIG. 3, for example, explanation information including meaning contents of the headwords is stored in association with a plurality of headwords. .

  The handwritten image table 84 stores a plurality of handwritten images input from the touch panel 110 as the contents of each side of the memorization card. More specifically, as shown in FIG. 4, each handwritten image corresponds to an identification number. It comes to remember.

  The memorization card database group 83 has a plurality of memorization card databases 830, and in this embodiment, memorization card databases 830a to 830c for English, Japanese, and Chinese for each language.

  In these memorization card database 830, for example, as shown in FIG. 5, the recognized character string (see the “key” column in the figure) input by handwriting input from the touch panel 110 and the memorization card database 830 The identification number of the recognized character string (see the column “ID” in the figure), the identification number of the recognition source handwritten image in the handwritten image table 84 (see the column “image ID” in the figure), and the opposite side of the same memorized card The language of the other recognized character string set as the content of the screen (see the “Link LANG” column in the figure) and the identification number of the other recognized character string in the memorized card database 830 of the language (“Link” in the figure) ID / correction information ”) is associated and stored.

  Here, the recognized character string in the memorized card database 830 and the identification number of the handwritten image of the recognition source link the recognized character string to the handwritten image of the recognized source, and indicate the contents of the same surface of the memorized card. It functions as the same plane information 60.

  The recognized character string in the memorized card database 830, the identification number of the recognized character string, the language of the other recognized character string, and the identification number of the other recognized character string are the contents of both sides of the same memorized card. The recognition character strings of the two input handwritten images are linked to each other, and function as reverse side information 61 indicating the content on the opposite side of the memorized card. In the present embodiment, when a memorized card test mode is executed in the later-described memorized card processing (see FIGS. 6 to 9) and the answer by the user is correct, the objection related to the test problem is reversed. The information is added to the surface information 61 and stored (see “OK” in the “Link ID / correction information” column in the figure).

  The RAM 90 includes a memory area that temporarily holds various programs executed by the CPU 20 and data related to the execution of these programs.

[Operation]
Next, the operation of the electronic dictionary 1 will be described with reference to FIGS.

  6 to 9 are flowcharts showing the flow of the memorization card process in which the CPU 20 reads and executes the information display program 81.

  As shown in FIG. 6, when the memorization card process is executed, first, the CPU 20 selects “new memorization card creation mode” or “registered memorization card search mode” by a user operation of the input unit 30. Is determined (step S1). The “new memorization card creation mode” is a mode in which a new memorization card is created in the electronic dictionary 1, and the “registered memorization card search mode” is a search for a created memorization card. This is the mode to perform.

  When it is determined in this step S1 that “new memorization card creation mode” or “registered memorization card search mode” is selected (step S1; Yes), the CPU 20 displays the contents of the memorization card on the main display 10. The screen is displayed, and after handwriting input on the touch panel 110 by the user and operation of the translation / decision key 2b are received (step S2), the handwritten image is recognized as a recognized character string (step S3).

  In the present embodiment, the content display screen of the memorized card has two card surface display frames 70a and 70b indicating the written contents of each surface of the memorized card, as shown in FIG. Characters “front” and “back” that distinguish the card surface display frames 70a and 70b for convenience are displayed. In addition, when there are a plurality of memorized cards having the same contents on one card face and different contents on the other card face, that is, the recognized character string linked to the handwritten image of one card face with the same face information 60 is the opposite face. When the information 61 is linked to a plurality of recognized character strings, the content display screen displays an arrow symbol 70c for switching display content in the vicinity of the card surface display frame 70a (or 70b) on the other card surface. Is displayed.

  Next, the CPU 20 determines whether or not the same plane information 60 of the same character string as the recognized character string is already stored in the memorization card database 830 (step S4), and when it is determined that it is not stored (step S4). No), the handwritten image is stored in the handwritten image table 84, and the identification number of the handwritten image and the recognized character string are associated with each other and stored in the memorized card database 830 as the same plane information 60 (step S6). . At this time, the CPU 20 displays the handwritten image on one card surface display frame 70a. Here, in step S6, the same plane information 60 may be stored in the memorized card database 830 of the language recognized by the recognized character string, or the same plane is stored in the memorized card database 830 of the language specified by the user. Information 60 may be stored. In addition, when the “registered memorization card search mode” is selected by the user in step S1 described above, the CPU 20 displays a message indicating that there is no corresponding registered memorization card after step S4. 40 (step S5), the process of step S6 is performed.

  Next, after receiving the handwriting input by the user on the touch panel 110 and the operation of the translation / decision key 2b (step S7), the CPU 20 recognizes the handwritten image as a recognized character string (step S8).

  Next, the CPU 20 determines whether or not the same plane information 60 of the same character string as the recognized character string is already stored in the memorization card database 830 (step S9), and when determining that it is stored (step S9). Yes), the recognized character string and the handwritten image of the recognition source are not newly stored in the memorized card database 830 and the handwritten image table 84, and the process proceeds to step S11 described later.

  If it is determined in step S9 that the same plane information 60 of the same character string as the recognized character string has not yet been stored (step S9; No), the CPU 20 stores the handwritten image in the handwritten image table 84. Then, the identification number of the handwritten image and the recognized character string are associated with each other and stored in the memorized card database 830 as the same plane information 60 (step S10). Here, in this step S10, the same plane information 60 may be stored in the memorized card database 830 of the language recognized by the recognized character string as in the above-described step S6, or the language specified by the user The same plane information 60 may be stored in the memorized card database 830.

  Next, the CPU 20 stores the opposite surface information 61 in the memorized card database 830 so as to link the two identical surface information 60 about the recognized character strings recognized in steps S3 and S8 (step S11). Specifically, the language and identification number of the other recognized character string are stored in association with one recognized character string, and the language and identification number of one recognized character string are stored in association with the other recognized character string. . Thereby, the recognized character strings of two handwritten images input as the contents of both sides of the same memorization card are linked by the opposite side information 61. Moreover, in this step S11, CPU20 displays the handwritten image on the other card surface display frame 70b, and displays on the display part 40 that the memory card was newly created. Further, at this time, the CPU 20 detects from the memorized card database 830 a recognized character string linked by the opposite surface information 61 to the recognized character string linked by the same surface information 60 to the handwritten image displayed in the card surface display frame 70b. When there are a plurality of detected recognized character strings, an arrow symbol 70c is displayed in the vicinity of the opposite card surface display frame 70a.

  Next, the CPU 20 performs an operation such as adding contents to either the front or back side of the memorized card by the user, specifically, for the character parts of “front” and “back” in the contents display screen of the memorized card. It is determined whether or not a touch operation, a touch operation on the inside of the card surface display frames 70a and 70b, or a touch operation on the arrow symbol 70c is performed (step S12). If it is determined that the touch operation is not performed (step S12; No) Then, the memorization card process is terminated.

  On the other hand, if it is determined in step S12 that the user has performed an additional operation (step S12; Yes), the CPU 20 performs a card surface addition process (step S13).

  Specifically, as shown in FIG. 7, first, the CPU 20 determines whether or not the character portion of “front” or “back” is touched in the content display screen of the memorized card on the main display 10. (Step S20). In the present embodiment, the touch operation on the character portions of “front” and “back” is performed on a card surface display frame 70a (or a non-addition surface) on the card surface where the character portion is not touched (or a non-addition surface). A new memorization card is created by writing new contents in the card surface display frame 70b (or 70a) of the touched card surface (hereinafter referred to as an additional surface) without changing the display content in 70b). Means that.

  When it is determined in this step S20 that any of the character parts “front” and “back” has been touched (step S20; Yes), the CPU 20 performs handwriting input on the touch panel 110 by the user regarding the contents of the additional surface. After accepting the operation of the translation / decision key 2b (step S21), the handwritten image is recognized as a recognized character string (step S22).

  Next, the CPU 20 determines whether the recognized character string of the additional surface is already stored in the memorized card database 830 and whether the recognized character strings of the additional surface and the non-added surface are linked by the opposite surface information 61. (Step S23) When it is determined that it is stored and linked (Step S23; Yes), the recognized character string of the additional surface and the handwritten image of the recognition source are stored in the memorized card database 830 and the handwritten image table 84. The fact that the same memorized card has been created is displayed on the main display 10 without newly storing it, and the card surface addition process and the memorized card process are terminated.

  In step S23, the additional surface recognition character string is not yet stored in the memorized card database 830, or the additional surface and non-addition surface recognition character strings are not linked by the opposite surface information 61 even if stored. (Step S23; No), the CPU 20 stores the handwritten image in the handwritten image table 84, and memorizes the identification number of the handwritten image and the recognized character string as the same plane information 60 in association with each other. The opposite side information 61 is stored in the memorized card database 830 so that the same side information 60 and the same side information 60 of the non-addition side are linked to each other (step S24). Note that storing the opposite surface information 61 so as to link the same surface information 60 to each other specifically means that the other surface information 60 is recognized in association with the recognition character string of the one surface information 60. The language and identification number of the character string are stored, and the language and identification number of the recognized character string of one coplanar information 60 are stored in association with the recognized character string of the other coplanar information 60. If it is determined in step S23 that the additional surface recognition character string is stored and the additional surface and non-addition surface recognition character strings are not linked by the opposite surface information 61, the CPU 20 performs handwriting in step S24. Without storing the image in the handwritten image table 84 and storing the same plane information 60 in the memorized card database 830, the stored same plane information 60 on the additional plane and the same plane information on the non-addition plane The opposite side information 61 is stored in the memorization card database 830 so that the two are linked to each other. In step S24, the CPU 20 updates the contents of the card surface display frame 70a (or 70b) of the additional surface to a new handwritten image, and displays on the display unit 40 that the memorized card is newly created. An arrow symbol 70c is displayed in the vicinity of the card surface display frame 70a (or 70b).

  Next, the CPU 20 determines whether or not the user performs an operation such as adding contents to either the front or back side of the memorized card (step S25), and determines that no additional operation is performed (step S25; In No), the card surface addition process and the memorization card process are terminated, and if it is determined that the addition operation has been performed (step S25; Yes), the process proceeds to step S20 described above.

  If it is determined in step S20 that neither “front” nor “back” is touched (step S20; No), the CPU 20 displays the memorized card content display screen in the main display 10. Then, it is determined whether or not the inside of the card surface display frames 70a and 70b has been touched (step S30). In the present embodiment, a touch operation on the inside of the card surface display frames 70a and 70b means that the contents of the card surface of the card surface display frame 70a (or 70b) are corrected.

  If it is determined in step S30 that the inside of the card surface display frames 70a and 70b has been touched (step S30; Yes), the CPU 20 performs handwriting input on the touch panel 110 by the user for the contents of the memorized card after correction, After accepting the operation of the translation / decision key 2b (step S31), the corrected handwritten image is recognized as a recognized character string (step S32).

  Next, the CPU 20 stores the handwritten image input in step S 31, that is, the corrected handwritten image in the handwritten image table 84, and deletes the unwritten handwritten image from the handwritten image table 84. Further, the CPU 20 links the recognized character string of the corrected handwritten image to the handwritten image and stores it in the memorized card database 830 as the same plane information 60, and the opposite surface information about the recognized character string of the corrected handwritten image. 61 is copied and stored as opposite surface information 61 about the recognized character string of the corrected handwritten image. And CPU20 deletes the same surface information 60 and the opposite surface information 61 about the recognition character string of the handwritten image before correction from the memorization card database 830 (step S33), and transfers to the above-mentioned step S25. In step S33, the CPU 20 updates the uncorrected handwritten image displayed in the card surface display frame 70a (or 70b) touched in step S30 to the corrected handwritten image.

  On the other hand, if it is determined in step S30 described above that the inside of the card surface display frames 70a and 70b is not touched (step S30; No), the CPU 20 determines whether or not the arrow symbol 70c on the content display screen has been touched. Is determined (step S40). In the present embodiment, as described above, when there are a plurality of memorized cards having the same contents on one surface and different contents on the other surface, the card surface display frame 70a ( 70b) An arrow symbol 70c is displayed in the vicinity, and a touch operation on the arrow symbol 70c is performed by a card surface display frame on a card surface (hereinafter referred to as a switching surface) on the touched arrow symbol 70c side. This means that the handwritten image 70a (or 70b) is switched.

  When it determines with the arrow symbol 70c not being touched in this step S40 (step S40; No), CPU20 complete | finishes a card surface addition process and a memorization card | curd process.

  On the other hand, if it is determined in step S40 that the arrow symbol 70c has been touched (step S40; Yes), the CPU 20 determines the card surface opposite to the card surface display frame 70a (or 70b) on the switching surface (hereinafter referred to as non-display). Recognized characters that can be displayed by switching each recognized character string linked by the opposite surface information 61 with respect to the recognized character string linked by the same surface information 60 to the handwritten image in the card surface display frame 70b (or 70a). Extracted from the memorized card database 830 as a column. Next, the CPU 20 selects one of the recognized character strings that can be switched and displayed as a recognized character string to be displayed, and a handwritten image linked to the recognized character string to be displayed with the same plane information 60 is displayed on the switching plane. The contents are displayed on the card surface display frame 70a (or 70b) to update the display contents (step S41), and the process proceeds to step S25 described above. In step S41, the CPU 20 displays a recognized character string different from the recognized character string of the handwritten image displayed in the card surface display frame 70a (or 70b) of the switching surface at the time of step S40. Is selected as the recognized character string. Further, in the present embodiment, if the CPU 20 determines that the arrow symbol 70c is further touched in the above-described step S25 after the process of step S41 (step S25; Yes), the recognized character that can be switched and displayed. The recognition character strings to be displayed are switched and selected between the columns in a predetermined order.

  As shown in FIG. 6, when it is determined in step S4 described above that the same surface information 60 of the same character string as the recognized character string is already stored in the memorization card database 830 (step S4; Yes), The CPU 20 displays on the display unit 40 that the corresponding registered memorization card has been detected (step S15).

  Next, the CPU 20 displays a handwritten image corresponding to the identification number of the same surface information 60 determined to be stored in step S4 on one card surface display frame 70a, and also recognizes the recognized character string of the same surface information 60. The other recognized character string linked with the opposite surface information 61 is detected, and the handwritten image linked with the other recognized character string with the same surface information 60 is displayed on the other card surface display frame 70b (step S16). Further, at this time, the CPU 20 stores in the memorized card database other recognized character strings linked by the opposite surface information 61 to the recognized character strings linked by the same surface information 60 to the handwritten images displayed in the card surface display frames 70a and 70b. When a plurality of frames are detected from 830, an arrow symbol 70c is displayed in the vicinity of the card surface display frame 70a (or 70b) on the opposite card surface.

  Next, CPU20 complete | finishes a memorization card | curd process, after performing the card surface addition process similar to said step S13 (step S17).

  If it is determined in step S1 that neither the “new memorization card creation mode” nor the “registered memorization card search mode” is selected (step S1; No), the CPU 20 as shown in FIG. Then, it is determined whether or not the “memorized card writing test mode” is selected by the user operation of the input unit 30 (step T1). The “memorized card writing test mode” is a mode in which the user performs a writing test using the memorized card created in the “memorized card new creation mode”.

  When it is determined in this step T1 that the “memorized card writing test mode” is selected (step T1; Yes), the CPU 20 displays a question condition setting screen on the main display 10, and the user selects the question condition. Determine (step T2). In the present embodiment, the question condition setting screen has a language selection frame 72a for selecting the language of the test question and a language for selecting the answer language, as shown in FIG. A language selection frame 72b, a correct question selection frame 72c for selecting whether or not to give a test question that has already been answered correctly, and an order selection frame 72d for selecting the order of test questions are displayed. ing. More specifically, in the language selection frames 72a and 72b, the language of the memorized card database 830 can be selected. In the order selection frame 72d, it is possible to select whether the test questions are given in the order of registration of the recognized character strings in the memorized card database 830 or whether the test questions are given randomly.

  Next, the CPU 20 displays a test screen on the main display 10 and, based on the language selected by the language selection frames 72a and 72b in step T2, the recognition character strings of test questions that can be given questions from the memorized card database 830. Extract (step T3). This narrows down the test questions to be presented. In the present embodiment, as shown in FIG. 15 and the like to be described later, a problem display frame 74a for displaying a handwritten image of a test question and an arrow symbol 74b for switching the test question are displayed on the test screen. It has come to be.

  Next, the CPU 20 determines whether or not a question other than a correctly answered test question has been selected according to the content selected by the correct question question selection frame 72c in step T2 (step T4). If it is determined that it has not been performed (step T4; No), the process proceeds to step T6 described later.

  On the other hand, if it is determined in step T4 that a question other than a correct test question has been selected (step T4; Yes), the CPU 20 corrects the test question among the recognized character strings extracted in step T3. A recognized character string that is not added to the opposite surface information 61 is extracted (step T5).

  Next, the CPU 20 determines whether or not the order selection frame 72d has been selected to issue the test questions in the order of registration of the recognized character strings in step T2 (step T6).

  If it is determined in step T6 that the order of registration is selected (step T6; Yes), the CPU 20 recognizes the recognition character string registered first in the memorization card database 830 among the already-recognized recognition character strings. A character string is detected, and a handwritten image linked to the recognized character string with the same plane information 60 is displayed as a test question in the problem display frame 74a (step T7).

  Next, the CPU 20 determines whether or not display of another problem is instructed by a touch operation on the arrow symbol 74b (step T8). If it is determined that the instruction is instructed (step T8; Yes), the CPU 20 has already narrowed down. Among the recognized recognized character strings, a recognized character string registered in the memorized card database 830 is detected in the order according to the instruction, and a handwritten image linked to the recognized character string with the same plane information 60 is set as a new test problem. After updating the display of the problem display frame 74a (step T9), the process proceeds to step T8 described above.

  On the other hand, when it is determined in step T8 that display of another problem is not instructed (step T8; No), the CPU 20 performs handwriting input on the touch panel 110 by the user for an answer and operation of the translation / decision key 2b. It is determined whether or not it is performed (step T10), and when it is determined that it is not performed (step T10; No), the process proceeds to step T8 described above.

  If it is determined in step T10 that the user has performed handwriting input on the touch panel 110 and operation of the translation / decision key 2b (step T10; Yes), the CPU 20 is against the recognized character string of the test question. A recognized character string linked by the face information 61 is detected as a recognized character string of the correct answer of the test question. Further, the CPU 20 recognizes the input handwritten image as a recognized character string, and then compares the recognized character string with the recognized character string of the correct answer (step T11) to determine whether or not they match. (Step T12).

  If it is determined in step T12 that the two recognized character strings match (step T12; Yes), the CPU 20 displays on the main display 10 that the answer is correct (step T13), and then determines the correct answer. The opposite side information 61 for linking the recognized character string of the test question to the recognized character string is added to the fact that the test question has been correctly answered and stored in the memorized card database 830 (step T14), and the memorized card processing is terminated. .

  If it is determined in step T12 that the two recognized character strings do not match (step T12; No), the CPU 20 displays on the main display 10 that the answer is incorrect (step T15). Then, the review mode is executed (step T16), and the memorization card process is terminated. Here, in the review mode of step T16, the CPU 20 displays a handwritten image linked to the recognized character string of the correct answer with the same plane information 60 on the main display 10, and the recognized character string of the correct answer is recognized. After handwritten input is received from the touch panel 110 a predetermined number of times (six times in the present embodiment), each handwritten image is displayed on the main display 10. In this review mode, when the recognized character string of the input handwritten image does not match the recognized character string of the correct answer, the CPU 20 does not count the input and causes the user to input handwriting again. Is preferred.

  On the other hand, if it is determined in step T6 that the order selection frame 72d has not been selected to issue the test questions in the order in which the recognized character strings are registered (step T6; No), the CPU 20 recognizes that it has already been narrowed down. Any one of the character strings is randomly detected, and a handwritten image linked to the detected recognized character string with the same plane information 60 is displayed on the problem display frame 74a as a test question (step T20).

  Next, the CPU 20 determines whether or not display of another problem is instructed by a touch operation on the arrow symbol 74b (step T21). If it is determined that the instruction has been instructed (step T21; Yes), the CPU 20 has already narrowed down. Any of the recognized character strings is randomly detected, and the handwritten image linked to the detected recognized character string with the same plane information 60 is set as a new test problem, and the display of the problem display frame 74a is updated (step) T22), the process proceeds to step T21 described above.

  On the other hand, when it is determined in step T21 that display of another problem is not instructed (step T21; No), the CPU 20 performs a handwriting input on the touch panel 110 by the user for an answer and an operation of the translation / decision key 2b. It is determined whether or not it is performed (step T23). When it is determined that it is not performed (step T23; No), the process proceeds to the above-described step T21, and when it is determined that it is performed (step T23; Yes). The process proceeds to step T11 described above.

  When it is determined in step T1 that the “memorization card writing test mode” is not selected (step T1; No), the CPU 20 performs the “memorization card” by the user operation of the input unit 30 as shown in FIG. It is determined whether or not “browsing mode” is selected (step U1), and if it is determined that it is not selected (step U1; No), the process proceeds to other processing. The “memorized card browsing mode” is a mode in which the memorized card created in the “memorized card new creation mode” is browsed one side at a time in a test format.

  If it is determined in this step U1 that the “memorized card viewing mode” is selected (step U1; Yes), the CPU 20 displays a viewing condition setting screen on the main display 10, and the user selects and determines the viewing conditions. (Step U2). In the present embodiment, the question condition setting screen includes a language selection frame 76a for selecting the language of the display surface of the memorized card and the “memorized card writing test mode” as shown in FIG. The correct face display selection frame 76b for selecting whether or not to display the card face of the memorized card that has already been correctly answered to the test question in "," and the order selection frame 76c for selecting the display order are displayed. ing. More specifically, in the language selection frame 76a, the language of the memorization card database 830 can be selected, and in the order selection frame 76c, handwritten images are displayed in the registered order of the recognized character strings in the memorization card database 830, or Whether to display at random can be selected.

  Next, the CPU 20 displays a card browsing screen on the main display 10 and extracts a recognizable character string of a displayable handwritten image from the memorized card database 830 according to the language selected by the language selection frame 76a in step U2. (Step U3). Thereby, the displayed handwritten image is narrowed down. In the present embodiment, as shown in FIG. 17 described later, the card browsing screen is for switching between a card surface display frame 77a for displaying a handwritten image on one side of a memorized card and a memorized card to be displayed. An arrow symbol 77b is displayed. When the card browsing screen is displayed on the main display 10, as shown in FIG. 17, an editing instruction button 700 for instructing editing of the memorized card being displayed is displayed on the sub-display 11. In addition, the opposite side of the memorized card being displayed is displayed on the card side display frame 77a by operating the translation / decision key 2b.

  Next, the CPU 20 determines whether or not a selection to display other than the face of the memorized card that has already been correctly answered in the test question is made according to the content selected by the correct face display selection frame 76b in step U2 ( If it is determined in step U4) that it has not been selected (step U4; No), the process proceeds to step U6 described later.

  On the other hand, if it is determined in step U4 that the screen other than the side of the memorized card that has already been correctly answered in the test question has been selected (step U4; Yes), the CPU 20 of the recognized character strings extracted in step U3. Then, a recognized character string that is not added to the opposite surface information 61 indicating that the test question has been correctly answered is extracted (step U5).

  Next, the CPU 20 determines whether or not the selection of displaying the handwritten image in the registered order of the recognized character string is made by the order selection frame 76c in step U2 (step U6).

  If it is determined in step U6 that the order of registration has been selected (step U6; Yes), the CPU 20 recognizes the recognition character string registered first in the memorization card database 830 among the already-recognized recognition character strings. A character string is detected, and a handwritten image linked to the recognized character string with the same surface information 60 is displayed on the card surface display frame 77a (step U7).

  Next, the CPU 20 determines whether or not an instruction to display the card surface of another memorized card is instructed by a touch operation on the arrow symbol 77b (step U8), and when it is determined that the instruction has been instructed (step U8; Yes). Detects the recognized character strings registered in the memorized card database 830 in the order according to the instruction from the already-recognized recognized character strings, and the handwritten images linked to the recognized character strings with the same plane information 60 are stored in the card. After displaying on the surface display frame 77a (step U9), the process proceeds to the above-described step U8.

  On the other hand, when it is determined in step U8 that the display of the card surface of another memorized card is not instructed (step U8; No), the CPU 20 determines whether or not the user operates the translation / decision key 2b. However, if it is determined that it has been performed (step U10; Yes), the CPU 20 uses the opposite surface information 61 for the recognized character string linked to the handwritten image of the card surface display frame 77a by the same surface information 60. Each recognized character string to be linked is extracted from the memorized card database 830 as a recognized character string that can be switched and displayed. Next, the CPU 20 selects any of these recognized character strings that can be switched and displayed as a recognized character string to be displayed, and displays a handwritten image linked to the recognized character string to be displayed with the same plane information 60 on the card surface. The display content is updated in the frame 77a (step U11), and the process proceeds to the above-described step U8. In step U11, the CPU 20 selects a recognized character string that is different from the recognized character string of the handwritten image displayed on the card surface display frame 77a at the time of step U10 as the recognized character string to be displayed. It is like that. Further, in the present embodiment, when the CPU 20 determines that the arrow symbol 77b is further touched in the above-described step U10 after the process of step U11 (step U10; Yes), the amount corresponding to this number of times is determined. The recognition character strings to be displayed are switched and selected in a predetermined order among the recognized character strings that can be switched and displayed only.

  If it is determined in step U10 that the translation / decision key 2b is not operated (step U10; No), the CPU 20 edits the editing of the memorized card displayed in the card surface display frame 77a. It is determined whether or not an instruction is made by the instruction button 700 (step U12). If it is determined that the instruction button 700 is not instructed (step U12; No), the memorization card process is terminated.

  If it is determined in step U12 that editing of the memorization card has been instructed (step U12; Yes), the CPU 20 performs handwriting input on the touch panel 110 by the user for the contents of the memorized card after correction, and translation / determination. After receiving the operation of the key 2b, the corrected handwritten image is recognized as a recognized character string. Further, the CPU 20 stores the input handwritten image, that is, the corrected handwritten image in the handwritten image table 84, and deletes the unwritten handwritten image from the handwritten image table 84. Further, the CPU 20 links the recognized character string of the corrected handwritten image to the handwritten image and stores it in the memorized card database 830 as the same plane information 60, and the opposite surface information about the recognized character string of the corrected handwritten image. 61 is copied and stored as opposite surface information 61 about the recognized character string of the corrected handwritten image. And CPU20 deletes the same surface information 60 and the opposite surface information 61 about the recognition character string of the handwritten image before correction from the memorization card database 830 (step U13), and transfers to the above-mentioned step U8. In Step U13, the CPU 20 updates the unwritten handwritten image displayed on the card surface display frame 77a to the corrected handwritten image.

  On the other hand, if it is determined in step U6 that the selection of displaying the handwritten image in the order of registration of the recognized character string is not made by the order selection frame 76c (step U6; No), the CPU 20 recognizes that the selection has already been narrowed down. Any one of the character strings is randomly detected, and a handwritten image linked to the detected recognized character string with the same surface information 60 is displayed on the card surface display frame 77a (step U20).

  Next, the CPU 20 determines whether or not an instruction to display the card surface of another memorized card is instructed by a touch operation on the arrow symbol 77b (step U21), and when it is determined that the instruction has been instructed (step U21; Yes). After randomly detecting any of the already-recognized recognized character strings and displaying the handwritten image linked to the detected recognized character string with the same surface information 60 on the card surface display frame 77a (step U22) The process proceeds to step U21 described above.

  On the other hand, when it is determined in step U21 that display of the card surface of another memorized card is not instructed (step U21; No), the CPU 20 determines whether or not the user operates the translation / decision key 2b. However, if it is determined that it has been performed (step U23; Yes), the CPU 20 uses the opposite surface information 61 for the recognized character string linked to the handwritten image of the card surface display frame 77a by the same surface information 60. Each recognized character string to be linked is extracted from the memorized card database 830 as a recognized character string that can be switched and displayed. Next, the CPU 20 selects any of these recognized character strings that can be switched and displayed as a recognized character string to be displayed, and displays a handwritten image linked to the recognized character string to be displayed with the same plane information 60 on the card surface. The contents displayed on the frame 77a are updated (step U24), and the process proceeds to the above-described step U21. In step U24, the CPU 20 selects a recognized character string that is different from the recognized character string of the handwritten image displayed on the card surface display frame 77a at the time of step U23 as the recognized character string to be displayed. It is like that. Further, in the present embodiment, when the CPU 20 determines that the arrow symbol 77b is further touched in the above-described step U23 after the processing in step U24 (step U10; Yes), the amount corresponding to this number of times. The recognition character strings to be displayed are switched and selected in a predetermined order among the recognized character strings that can be switched and displayed only.

  If it is determined in step U23 that the translation / decision key 2b is not operated (step U23; No), the CPU 20 edits the editing of the memorized card displayed in the card surface display frame 77a. It is determined whether or not an instruction is made by the instruction button 700 (step U25). If it is determined that the instruction button 700 is not instructed (step U25; No), the memorization card process is terminated.

  If it is determined in step U25 that editing of the memorization card is instructed (step U25; Yes), the CPU 20 performs handwriting input on the touch panel 110 by the user for the contents of the memorized card after the correction, and translation / determination. After receiving the operation of the key 2b, the corrected handwritten image is recognized as a recognized character string. Further, the CPU 20 stores the input handwritten image, that is, the corrected handwritten image in the handwritten image table 84, and deletes the unwritten handwritten image from the handwritten image table 84. Further, the CPU 20 links the recognized character string of the corrected handwritten image to the handwritten image and stores it in the memorized card database 830 as the same plane information 60, and the opposite surface information about the recognized character string of the corrected handwritten image. 61 is copied and stored as opposite surface information 61 about the recognized character string of the corrected handwritten image. And CPU20 deletes the same surface information 60 and the opposite surface information 61 about the recognition character string of the handwritten image before correction from the memorization card database 830 (step U26), and transfers to the above-mentioned step U21. In Step U26, the CPU 20 updates the unwritten handwritten image displayed on the card surface display frame 77a to the corrected handwritten image.

The correctness of the answer is determined based on whether or not it matches the recognized character string, and the determination result is displayed, so one side of the card is presented as a problem, and the content of the other side is input by handwriting. Can be tested. Therefore, the learning effect can be further enhanced.

  Also, as shown in FIG. 5 and FIG. 8, step T3, FIG. 15, etc., a recognized character string is stored for each language, and among the stored recognized character strings, the recognized character string of the language selected by the user is stored. Since any handwritten image linked with the same plane information 60 is displayed as a test question, the user can specify the language for the test question. Therefore, the learning effect can be further enhanced.

  Further, as shown in steps T5, T14, FIG. 15 and the like in FIG. 5 and FIG. 8, when the answer to the test question is determined to be correct, the recognition is linked to the handwritten image of the test question with the same plane information 60. The opposite side information 61 obtained by linking the character string and the recognized character string of the correct answer is added and stored with the fact that the test question is correctly answered, and is added according to the user operation. Since the handwritten image linked to the recognized character string of the detected opposite surface information 61 with the same surface information 60 is displayed as a test question, an uncorrected test question may be given. it can. Therefore, the learning effect can be further enhanced.

  Further, as shown in step T16 of FIG. 15, FIG. 16 and the like, when the answer to the test question is determined to be incorrect, a handwritten image linked to the recognized character string of the correct answer with the same plane information 60 is displayed. At the same time, handwritten input that allows the recognized character string of the correct answer to be recognized is accepted a predetermined number of times, so that the wrong test questions can be reviewed by handwriting input. Therefore, the learning effect can be further enhanced.

  Further, as shown in step U11 of FIG. 9, FIG. 17, etc., after an arbitrary handwritten image is displayed as the contents of the first surface of the card, the recognition is linked to the handwritten image of the first surface with the same surface information 60. When a plurality of recognized character strings on the second surface linked with the opposite surface information 61 are detected with respect to the character string, one of the recognized character strings on the second surface is displayed. A handwritten image selected as the recognized character string and linked to the recognized character string to be displayed with the same plane information 60 is displayed as the second surface of the memorized card and another handwritten image as the second surface of the memorized card. Is displayed as an arrow symbol 77b or the like, and the recognition character string to be displayed is sequentially switched among the plurality of recognition character strings on the second surface in response to a user operation. Multiple surfaces If you are associated as a surface it can be confirmed by switching the associated surfaces. Therefore, the learning effect can be further enhanced.

  Further, as shown in step S33 of FIG. 7, FIG. 11 and the like, when the user gives an instruction to correct the contents of an arbitrary surface of the memorized card, the handwritten image input as the corrected contents is stored. In addition, the stored handwritten image before correction is deleted, and the recognized character string of the corrected handwritten image is linked to the handwritten image and stored as the same plane information 60, and the same plane of the handwritten image before correction is stored. The information 60 is deleted, and the opposite surface information 61 about the recognized character string of the handwritten image before correction is stored as the opposite surface information 61 about the recognized character string of the corrected handwritten image. Even if there is an error in the content, the content can be corrected.
