  FIG. 18 is a flowchart for explaining the operation of classroom server processing in which the CPU 25 reads and executes the server-side class support program 240 from the storage unit 24.

  In this classroom server process, first, the CPU 25 determines whether or not any electronic blackboard 3B receives a book browsing request by a teacher's operation (step W101), and determines that it does not receive (step W101; No). ) Shifts to other processing.

  When it is determined in step W101 that any electronic blackboard 3B has received a book browsing request (step W101; Yes), the CPU 25 receives the electronic blackboard 3B (hereinafter referred to as another electronic blackboard 3B). The blackboard ID and classroom ID stored in the ID table 345 of the electronic blackboard 3S are received from the electronic blackboard 3S (step W102).

  Next, the CPU 25 separates the electronic blackboard 3S and each student terminal 4B corresponding to the electronic blackboard 3S (hereinafter referred to as the student terminal 4S separately from the other student terminals 4B) for lessons in the classroom indicated by the received classroom ID. Is created in the storage unit 24 (step W103).

  Next, after receiving the designation information of the book to be browsed from the electronic blackboard 3S (step W1), the CPU 25 determines whether or not the textbook is designated (step W2), and if not received. When it determines (step W2; No), it transfers to another process.

  If it is determined in step W2 that the textbook has been designated (step W2; Yes), the CPU 25 finally performs the textbook chapter and page number designation operation or last electronic blackboard processing. The designated operation of the displayed page is received from the user (teacher) through the electronic blackboard 3S (step W3).

Next, the CPU 25 sets the display mode of the display 310 in the electronic blackboard 3S and the student terminal 4S to the page mode (step W4).
Next, the CPU 25 transmits the textbook data D to the electronic blackboard 3S and the student terminal 4S, and among the pages of the textbook designated at step W1 (hereinafter referred to as designated textbook), the page designated at step W3 is selected. It is displayed on the displays 310 and 410 of the electronic blackboard 3S and the student terminal 4S (step W5).

  At this time, the CPU 25 displays a plurality of tags Tg for switching display contents on the right ends of the displays 310 and 410 in the electronic blackboard 3S and the student terminal 4S. More specifically, at this time, the CPU 25 displays a page tag Tg2, a body tag Tg1, a reference tag Tg3, and the like as a plurality of tags Tg, and displays the page tag Tg2 in a selected state.

  At this time, the CPU 25 displays a plurality of soft keys K for instructing the execution of a predetermined blackboard function on the lower end of the display 310 in the electronic blackboard 3S, and the soft key K for instructing the execution of the learning support function. Is displayed on the lower end of the display 410 in the student terminal 4S.

  Next, the CPU 25 determines whether or not the blackboard function execution is designated in the electronic blackboard 3S (step W7).

  If it is determined in this step W7 that the blackboard function execution has been designated (step W7; Yes), the CPU 25 designates any part of the text displayed on the electronic blackboard 3S as the position designation or It is determined whether or not a range designation has been received (step W8).

  If it is determined in step W8 that any part of the text has been designated for position designation or range designation from the electronic blackboard 3S (step W8; Yes), the CPU 25 temporarily stores the designated position or designation range. (Step W9), the process proceeds to Step W11 described later.

  On the other hand, if it is determined in step W8 that any part of the text has not been received from the electronic blackboard 3S (position W8, No.) (step W8; No), the CPU 25 displays the text on the electronic blackboard 3S. The first part of the existing text is temporarily stored as the designated position (step W10).

  Next, the CPU 25 reads the restriction target function corresponding to the designated blackboard function (restriction target function corresponding to the blackboard function designation operation) from the blackboard function-specific function restriction table 442 and temporarily stores it (step W105).

Next, the CPU 25 determines whether or not the voice function is designated as the blackboard function (step W11).

Transmit (step W12). In step W12, the CPU 25 transmits the type of restriction target function temporarily stored in step W105 (the type of restriction target function corresponding to the voice function) to the student terminal 4S. The execution is prohibited, and the soft key K corresponding to the function to be restricted is shaded in yellow to indicate that the function is restricted.

  Next, the CPU 25 sets the designated position (or the beginning of the designated range) as the voice output start position and transmits it to the electronic blackboard 3S (step W13), and causes the speaker 370 of the electronic blackboard 3S to output voice (step S13). W14). At this time, the CPU 25 transmits the position information of the text portion that is currently output as voice to the student terminal 4S.

  Next, the CPU 25 causes the electronic blackboard 3S and the student terminal 4S to display one sentence of the voice output target in blue, and changes the display color of the voice output portion in the sentence to red (step W15).

  Then, the CPU 25 determines whether or not the voice has been output up to the end of the text (or the end of the specified range) (step W16), and if it is determined that the voice has not been output (step W16; No), the above-described step. On the other hand, if it is determined that the sound is output (step W16; Yes), the process proceeds to the above-described step W7.

  If it is determined in step W11 that the voice function is not specified (step W11; No), the CPU 25 determines whether or not the reading function is specified (step W21).

  When it is determined in step W21 that the reading function is designated (step W21; Yes), the CPU 25 informs the student terminal 4S that the reading function is designated and the designated position (or designated range) in the text. Transmit (step W22). In step W22, the CPU 25 transmits the type of restriction target function temporarily stored in step W105 (the type of restriction target function corresponding to the reading function) to the student terminal 4S, and the restriction of the restriction target function in the student terminal 4S. The execution is prohibited, and the soft key K corresponding to the function to be restricted is shaded in yellow to indicate that the function is restricted.

  Next, the CPU 25 sets the designated position (or the beginning of the designated range) as the reading start position and transmits it to the electronic blackboard 3S (step W23), causes the microphone 371 of the electronic blackboard 3S to input voice, and recognizes the voice. (Step W24). At this time, the CPU 25 transmits the position information of the text portion being read at present to the student terminal 4S.

  Next, the CPU 25 causes the electronic blackboard 3S and the student terminal 4S to display one sentence to be read in blue, and changes the display color of the portion read in the sentence to red (step W25).

  Then, the CPU 25 determines whether or not the text has been read to the end (or the end of the specified range) (step W26). If it is determined that the text has not been read (step W26; No), the CPU 25 proceeds to the above-described step W24. On the other hand, if it is determined that the reading has been performed (step W26; Yes), the process proceeds to the above-described step W7.

  If it is determined in step W21 that the reading function is not specified (step W21; No), the CPU 25 determines whether the practice / question function is specified (step W31).

  If it is determined in step W31 that the practice / question function is designated (step W31; Yes), the CPU 25 indicates that the practice / question function is designated and the designated position (or designated range) in the text. It transmits to the student terminal 4S (step W32). In step W32, the CPU 25 transmits the type of restriction target function temporarily stored in step W105 (the type of restriction target function corresponding to the practice / question function) to the student terminal 4S. The function execution is prohibited, and the soft key K corresponding to the restriction target function is shaded in yellow to indicate that the function is restricted.

  Next, the CPU 25 displays the assignment window W at the designated position (or the end of the designated range) of the electronic blackboard 3S and the student terminal 4S (step W33).

  Next, the CPU 25 displays an assignment sentence on the assignment window W of the electronic blackboard 3S based on the received content of the input operation at the electronic blackboard 3S (step W34). More specifically, at this time, when the practice function is designated, the CPU 25 displays the assignment described in the textbook on the assignment window W, while when the questioning function is designated, the user is displayed. The task sentence input to (teacher), the task sentence that is the copy and paste operation target, and the like are displayed in the task window W.

  Next, the CPU 25 transmits an assignment sentence to the student terminal 4S and displays it on the assignment window W (step W35), and then proceeds to the above-described step W7.

  If it is determined in step W31 that the practice / question function is not designated (step W31; No), the CUP 35 determines the type of designated blackboard function and the designated position (or designated range) in the text. Are transmitted to the student terminal 4S (step W37).

  Then, the CPU 25 executes processing for the designated function (step W38), and proceeds to the above-described step W7. The functions executed in step W38 can include a page movement function, a zoom function, a handwriting input function, a marker function, a dictionary function, and the like.

  If it is determined in step W7 that the blackboard function execution is designated (step W7; No), the CPU 25 indicates that the tag Tg switching operation has been performed on the electronic blackboard 3S. Is determined (step W41).

  If it is determined in step W41 that the tag Tg switching operation has been received (step W41; Yes), the CPU 25 specifies the restriction target function (tag Tg designation operation) corresponding to the switching destination tag Tg. Is read from the tag-specific function restriction table 443 and temporarily stored (step W109).

Next, the CPU 25 determines whether or not a switching operation has been performed on the text tag Tg1 (step W42).
If it is determined in step W42 that the switching operation for the body tag Tg1 has been performed (step W42; Yes), the CPU 25 indicates that the switching to the body tag Tg1 has been performed and the page number currently displayed. Is transmitted to the student terminal 4S (step W43). In step W43, the CPU 25 transmits the type of restriction target function temporarily stored in step W109 (the type of restriction target function corresponding to the text tag Tg1) to the student terminal 4S, and the restriction target function in the student terminal 4S. And the soft key K corresponding to the function to be restricted is shaded in yellow to indicate that the function is restricted.

  Next, the CPU 25 sets the display mode of the displays 310 and 410 in the electronic blackboard 3S and the student terminal 4S to the text mode, and transmits the text of the currently displayed page to the electronic blackboard 3S and the student terminal 4S for display. 310 and 410 are displayed (step W44), and the process proceeds to the above-described step W7.

  If it is determined in step W42 that the switching operation for the body tag Tg1 has not been performed (step W42; No), the CPU 25 determines whether the switching operation for the page tag Tg2 has been performed (step W45). .

  If it is determined in step W45 that the switching operation for the page tag Tg2 has been performed (step W45; Yes), the CPU 25 indicates that switching to the page tag Tg2 has been performed and the page number currently displayed. Are transmitted to the student terminal 4S (step W46). In step W46, the CPU 25 transmits to the student terminal 4S the type of restriction target function temporarily stored in step W109 (the type of restriction target function corresponding to the page tag Tg2). And the soft key K corresponding to the function to be restricted is shaded in yellow to indicate that the function is restricted.

  Next, the CPU 25 sets the display mode of the displays 310 and 410 in the electronic blackboard 3S and the student terminal 4S to the page mode, transmits the currently displayed page to the electronic blackboard 3S and the student terminal 4S, and displays it as it is. 310 and 410 are displayed (step W47), and the process proceeds to the above-described step W7.

  When it is determined in step W45 that the switching operation for the page tag Tg2 is not performed, that is, when it is determined that the switching operation for the tag Tg other than the body tag Tg1 and the page tag Tg2 is performed (step W45; No). The CPU 25 transmits the type of the tag Tg for which the switching operation has been performed and the page number currently displayed to the student terminal 4S (step W51), and the contents of the tag Tg are transmitted to the electronic blackboard 3S and the student terminal 4S. Are displayed on the displays 310 and 410 (step W52), and the process proceeds to the above-described step W7. In step W51, the CPU 25 transmits the type of restriction target function temporarily stored in step W109 (the type of restriction target function corresponding to the tag Tg) to the student terminal 4S. The execution is prohibited, and the soft key K corresponding to the function to be restricted is shaded in yellow to indicate that the function is restricted.

  Further, when it is determined in step W41 that the tag Tg switching operation has not been received (step W41; No), the CPU 25 determines whether or not another operation has been performed. If it is determined that the signal has been received (step W53; Yes), the process corresponding to the operation is performed. On the other hand, if it is determined that the signal has not been received (step W53; No), the above-described process is performed. The process proceeds to step W7.
