  FIG. 8 is a flowchart showing textbook display processing (home learning) accompanying the student terminal processing (home learning mode) of the student terminal 10P.

  When the student terminal 10P is turned on (step S1), it is determined whether or not an access signal transmitted at regular time intervals from the classroom server 30 shown in FIG. 4 has been received (steps S2 and S3). .

  When it is determined that the student terminal 10P has entered the communication range of the classroom system and an access signal from the classroom server 30 has been received (step S3 (Yes)), the operation mode of the student terminal 10P is “classroom mode”. (Step S4), the operation of audio output by the audio output unit 28 is prohibited (step S5). And the attendance information matched with terminal ID is transmitted to the classroom server 30 (step S6).

  Then, the timetable data indicating the current lesson subject transmitted from the classroom server 30 is received (step S7), and the reading and display of the textbook data 22bn... Other than the designated lesson subject is prohibited (step S8).

  And it transfers to the textbook display process (classroom) in FIG. 6 (step SA).

  When the textbook display process (classroom) is entered, first, the textbook data 22bn of the lesson subject corresponding to the timetable data received from the classroom server 30 is read out from the textbook data storage area 22b. A page of a table of contents is displayed on the touch panel display unit 11 (step A1).

  When this page of the table of contents is displayed, if a page (Chapter n, Section m), for example, that is to be taught this time is specified in response to a user's touch operation (Step A2, A3 (Yes)), it corresponds. The designated page data is read from the textbook data 22bn (step A4).

  Then, it is determined whether or not a display format designated by the user is registered in the format data storage area 22c in association with the designated page (chapter n, chapter m) (step A5).

  If it is determined that the display format associated with the designated page (chapter n, section m) is registered (step A5 (Yes)), the display format is displayed in the registered display format. From the text screen of the corresponding page and other screens included in it according to the location information of the text screen and other screens included in it (still image screen, top image screen of moving image, screen of attached materials, etc.) Is generated (step A6) and displayed on the touch panel display unit 11 (step A8).

  On the other hand, when it is determined that the display format associated with the designated page (chapter n, section m) is not registered (step A5 (No)), the text screen of the corresponding page is displayed on the touch panel. It is generated in accordance with the full screen size of the unit 11 (step A7) and displayed on the touch panel display unit 11 (step A8).

  Here, when another page is designated in accordance with the user operation (step A9 (Yes)), the process returns to the reading process for the data of the designated new page (step A4).

  Thus, when it is determined that there is an instruction to scroll the screen by a touch operation with a slide in a state where a text screen of an arbitrary page (or a text screen and other screens included therein) is displayed on the touch panel display unit 11 ( Step A10 (Yes)), the content of the text screen (or other screen) where the slide operation has been performed is scrolled and read (Step A11), and the display screen after the scroll is generated and displayed (Step A10).

  Then, according to the display format data corresponding to the page data and moving image data being displayed on the teacher terminal 10T received from the teacher terminal 10T, the corresponding textbook data 22bn page (chapter n, section m) and moving image are displayed. The text screen Gt is read out and the text screen Gt is displayed (step S11), and the moving image playback screen Gm is reproduced and output with sound (step S12). That is, even in the “classroom mode” in which audio output is normally prohibited, when the same video is played on each student terminal 10P in response to a forced video playback instruction from the teacher terminal 10T, an exception is made. The prohibition of audio output is released, and a moving image is reproduced with audio from the audio output unit 28.

  Thereafter, when it is determined that the power key (27) has been operated (step S13 (Yes)), the power is turned off (step S14), and the operation of the student terminal 10P in the series of “classroom modes” is ended. The

  On the other hand, when the student terminal 10P is turned on (step S1), the access signal transmitted at regular time intervals from the classroom server 30 shown in FIG. 4 is not received, and the communication range of the classroom system is not received. If it is determined that there is no classroom (steps S2 and S3 (No)), the operation mode of the student terminal 10P is set to “home learning mode” (step S15), and the textbook display process (home learning) in FIG. Transition is made (step SB).

  When the textbook display process (home learning) is started, a textbook selection screen including a list of textbook data 22bn... Stored in the textbook data storage area 22b is first displayed on the touch panel display unit 11 ( Step B1).

  When an arbitrary textbook name is selected on the textbook selection screen (step B2 (Yes)), the selected textbook data 22bn is read from the textbook data storage area 22b and the first page of the table of contents is displayed. The page is displayed on the touch panel display unit 11 (step B3).

  When the page of the table of contents is displayed, for example, when a page to be learned this time (chapter n, chapter m) is designated in response to the student's touch operation (step B4 (Yes)), the above figure is referred to. The textbook display process (classroom) described with reference to FIG. 6 operates in the same manner as in steps A3 to A14, and displays the text screen and still image of the specified page data, the top image of the movie, and the screen of the attached material. Processing (steps A3 to A9), scrolling of display contents on each screen (steps A10 to A12, A8), and moving image designation / playback processing (steps A13, A14, A8) are executed. In the “home study” mode of the student terminal 10P, the audio output prohibiting process for the audio output unit 28 is not included. Therefore, in the moving image designating / reproducing process in the steps A13, A14, A8, the audio together with the moving image is recorded. Is also played.

  Thereafter, when it is determined that the power key (27) has been operated (step S16 (Yes)), the power is turned off (step S14), and the operation of the student terminal 10P in the series of “home learning mode” is completed. Is done.

In this teacher terminal process, there is no setting of “classroom mode” and “home learning mode”. Therefore, in the moving picture designation / playback process in steps A13, A14, A8, the teacher terminal 10T is used together with the moving picture. Audio is also played.

  In the textbook data 22bn display (playback) state in accordance with the textbook display process (classroom) (step SA (A3 to A14)) in the teacher terminal 10T, a video playback operation is performed by the processing of steps A13 and A14. (Step C5 (Yes)), the display format of the text screen Gt of the page being displayed on the teacher terminal 10T (Chapter n, Section m) and the screen Gm of the movie that has been played back is changed. A video reproduction signal is transmitted to each student terminal 10P in the classroom via the classroom server 30 of the classroom system (see FIG. 4) in order to unify all the student terminals 10P in the classroom (step C6). ).

  Accordingly, the page data being displayed (chapter n, section m) and the display format data of the replayed moving image are transmitted to each student terminal 10P in the classroom (step C7). .

  Thereafter, when it is determined that the power key (27) has been operated (step C8 (Yes)), the power is turned off (step C9), and the operation of the series of teacher terminals 10T is ended.

  Therefore, according to the teacher terminal 10T and the student terminals 10P using the information terminal device 10 in the classroom system having the above-described configuration, any page (first page) of any textbook data 22bn by any user can be found at any terminal 10T, 10P. The text screen Gt can be displayed by designating (chapter n, section m), and the video screen Gm can be reproduced with sound by designating any video of the textbook data 22bn.

  When the student terminal 10P enters the communication range of the classroom server 30 and is set to “classroom mode”, the display of the textbook data 22bn other than the class subject according to the timetable data received from the classroom server 30 is prohibited. Is done. Moreover, the audio output of the student terminal 10P is prohibited, and when a moving image is designated by a user (student) operation, the sound is not output, and only the image of the designated moving image is reproduced. When a forced video playback signal (including a page being displayed on the teacher terminal 10T and a display format corresponding to the video) transmitted from the teacher terminal 10T in response to the playback operation of the video is received by the student terminal 10P The student terminal 10P displays the text screen Gt of the page corresponding to the received display format and reproduces the moving image screen Gm with sound.
