Next, the operation of the above embodiment will be described.
3 and 4 show the transparent touch panel 16t of the handwriting input unit (sub-screen) 16 and the touch-panel color display unit (main screen) 17 that are executed when the book content is browsed. It is a flowchart which shows the process with respect to the touch operation to the transparent touch panel 17t.
5 to 12 are diagrams schematically illustrating a process in which the user holds the electronic dictionary device 10 with one hand while browsing the book content and performs a touch operation with the transparent touch panels 16t and 17t.
FIG. 5 shows a basic holding method of the electronic dictionary device 10 when browsing book contents mainly composed of vertically written sentences such as Japanese literature. As shown in FIG. 4B, the main body case 11 is held with the left hand LH and the lid case 12 is held with the right hand RH, and the entire electronic dictionary device 10 is held in a landscape orientation. This gripping state is hereinafter referred to as “horizontal holding” in the text. At this time, the thumb of the left hand LH may touch any area of the transparent touch panel 16t of the handwriting input unit (sub-screen) 16, but in the present embodiment, the transparent touch panel 16t is shown in FIG. 5A, for example. It is assumed that display control is executed according to each of the upper, middle and lower operation positions.

  On the other hand, FIG. 6 shows a basic holding method of the electronic dictionary device 10 when browsing book contents mainly composed of horizontal writing such as English-American literature. As shown in FIG. 5B, the electronic case device 10 is held vertically by holding the main body case 11 with the left hand LH from the lower side and the lid case 12 with the right hand RH from the right side. Indicates. This holding state is hereinafter referred to as “vertical holding” in the text. At this time, the thumb of the left hand LH may touch any area of the transparent touch panel 16t of the handwriting input unit (sub-screen) 16, but in the present embodiment, the transparent touch panel 16t is shown in FIG. 6A, for example. In this way, the display area is divided into three areas, and display control corresponding to the left, middle and right operation positions is executed.

  In the following, a case will be described in which book content is browsed by the electronic dictionary device 10 in the horizontal orientation described with reference to FIG. 3 and 4, the CPU 21 first determines whether or not the book content browsing function is selected (step S101).

  Here, when it is determined that a function other than reading the book content is selected, the CPU 21 performs a control operation in accordance with the selected function. However, the description here assumes that the function is not directly related to the present embodiment. Is omitted.

  If it is determined in step S101 that the book content browsing function is selected, the CPU 21 then accepts designation from the book contents stored in the book database 22B of the program memory 22 (step S102).

  In this case, a part of the titles of the book contents stored in the book database 22B is displayed as a list on the touch panel type color display unit (main screen) 17, and displayed as a list by operating the cursor key of the key input unit 14 if necessary. The book content is selected by accepting that an arbitrary title position on the touch panel type color display unit (main screen) 17 is touched after moving the title range.

  The CPU 21 that has accepted the selection of the book content then detects the orientation of the main body case 11 and the lid case 12 based on the outputs of the three-axis acceleration sensor 27 and the open / close switch 28 (step S103).

  Based on the detection result, the CPU 21 determines whether or not the electronic dictionary device 10 is in the vertical holding state as shown in FIG. 6 (step S104).

  Here, when it is determined that the electronic dictionary device 10 is in the vertical holding state, the CPU 21 sets the text of the book content to be displayed horizontally (step S105).

  If it is determined in step S104 that the electronic dictionary device 10 is not vertically held, the CPU 21 determines that the electronic dictionary device 10 is vertically held and is in a horizontally held state as shown in FIG. The content text is set to be displayed vertically (step S106).

  After the vertical writing or horizontal writing display setting, the CPU 21 sets the past browsing data corresponding to the book content to be browsed designated in step S102, that is, the mark position stored in the marker data 22C, or bookmark data 22D. It is determined whether or not bookmark position data stored in is stored (step S107).

  Here, when the browsing data is not stored in either the marker data 22C or the bookmark data 22D, the user determines that the selected book content is to be browsed for the first time, and performs necessary processing such as explanation of the author and introduction of the synopsis. The description is omitted here because it is not directly related to the present embodiment.

  If it is determined that the browsing data of the book content selected in step S107 is stored in the marker data 22C or the bookmark data 22D, the CPU 21 determines that the previous user has read the book based on the stored browsing data. The book content is set to be displayed from the last page where the content has been browsed or the row of the bookmark position designated by the user (step S108).

  After that, the CPU 21 detects the output of the transparent touch panel 16t in the handwriting input unit (sub-screen) 16 and the output of the transparent touch panel 17t in the touch-panel color display unit (main screen) 17 (step S109), and from these detection outputs, the electronic dictionary It is determined whether or not the device 10 is in a gripping state (step S110).

  Here, when it is determined from the detection output of the transparent touch panel 16t and the detection output of the transparent touch panel 17t that neither of them is touched and the electronic dictionary device 10 is not gripped by the user, the CPU 21 determines that the electronic dictionary device 10 The process shifts to a process other than the process according to the gripping state, but the description thereof is omitted here because it is not directly related to the present embodiment.

  If it is determined in step S110 that the electronic dictionary device 10 is held, the CPU 21 determines whether or not a touch operation has been performed on the transparent touch panel 16t on the handwriting input unit (sub-screen) 16 side (step S111).

  If it is determined that a touch operation has been performed on the transparent touch panel 16t, the CPU 21 determines whether or not the touched position is the “upper” side region in the horizontal holding state of FIG. Step S112).

  If the CPU 21 determines that the position touched on the transparent touch panel 16t is the “upper” side area in the horizontal state, the CPU 21 then touches the touch operation position on the transparent touch panel 17t on the touch panel type color display (main screen) 17 side. It is determined whether or not a slide operation for moving is performed (step S113).

  At this time, when an operation other than the slide operation in which the touch operation position moves is performed, the CPU 21 shifts to a process corresponding to the operation, but the description thereof is omitted here because it is not directly related to the present embodiment.

  If it is determined in step S113 that the slide operation for moving the touch operation position has been performed, the CPU 21 scrolls the display screen on the color liquid crystal display screen 17d according to the slide direction (step S114), and then again Returning to the process from step S110, the process for the next operation is awaited.

  FIG. 7A illustrates such an operation state. Here, as shown by (A-1) in FIG. 7A, the user operates the “upper” side of the handwriting input unit (sub-screen) 16 with the thumb of the left hand LH. ), The slide operation is performed with the thumb of the right hand RH so as to move to the right side of the main screen 17 as indicated by the arrow A11 on the transparent touch panel 17t of the touch panel type color display unit (main screen) 17.

  Therefore, by scrolling the display screen according to the direction of the slide operation in this way, the display position of the book content can be moved with a natural operation feeling as if the paper surface of the book is shifted with a finger.

  If it is determined in step S112 that the position touched on the transparent touch panel 16t is not the “upper” side area in the horizontal holding state, the CPU 21 then determines that the position touched on the transparent touch panel 16t is in the horizontal holding state. It is determined whether or not the area is the “middle” side (step S115).

  When the CPU 21 determines that the position touched on the transparent touch panel 16t is the “middle” side area in the horizontal holding state, the CPU 21 then touches the touch operation position on the transparent touch panel 17t on the touch panel type color display (main screen) 17 side. It is determined whether or not a slide operation for moving in the horizontal direction has been performed (step S116).

  At this time, if it is determined that a slide operation in which the touch operation position moves in the left-right direction has been performed, the CPU 21 updates the display screen on the color liquid crystal display screen 17d in units of pages according to the slide direction (step S117). Then, the process returns to the process from step S110 again to wait for the process for the next operation.

  FIG. 7B illustrates such an operation state. Here, as shown by (B-1) in FIG. 7B, the user operates the “middle” side of the handwriting input unit (sub-screen) 16 with the thumb of the left hand LH. ), The slide operation is performed with the thumb of the right hand RH so as to move to the right side of the main screen 17 as indicated by the arrow A12 on the transparent touch panel 17t of the touch panel type color display section (main screen) 17.

  Therefore, by updating the display screen to the next page according to the direction of the slide operation in this way, the display position of the book content is updated in units of pages with a natural operation feeling as if the page of the book is being turned with a finger. Can be made.

  The touch operation described in FIG. 7 and steps S114 and S17 is the home position operation state with the “upper” side of the handwriting input unit (sub-screen) 16 as the home position and the “middle” side as the shift position. When the slide operation is performed on the touch panel type color display unit (main screen) 17 side, the screen scroll according to the operation direction is moved to the shift position, and the touch panel type color display unit (main screen) 17 is operated. This is an explanation of an operation example in the case of performing a page unit update when a slide operation is performed on the side.

  As described above, the home position and shift position on the handwriting input unit (sub-screen) 16 side are not fixed, but the operation position is changed from the state where one area has been operated to the adjacent area temporarily. If it is determined that the state of moving is the movement from the home position to the shift position, the same operating environment can be realized without fixing the position of the home position.

  If it is determined in step S116 that an operation other than the slide operation in which the touch operation position moves in the horizontal direction is performed on the transparent touch panel 17t on the touch panel type color display unit (main screen) 17 side, then the touch panel type color display is performed. It is determined whether or not a touch operation at one point in the character string displayed on the section (main screen) 17 or a touch operation along the character string direction has been performed (step S121).

  When it is determined that an operation other than a touch operation at one point in the character string displayed here or a touch operation along the character string direction has been performed, the CPU 21 proceeds to processing according to the operation. The description is omitted here because it is not directly related to the form.

  If it is determined that one point touch operation in the character string displayed in step S121 or a touch operation along the character string direction has been performed, the CPU 21 then determines whether the dictionary content used last time was a mini dictionary. Is determined (step S122).

  If it is determined that the previously used dictionary content is a mini-dictionary, the CPU 21 searches the mini-dictionary stored in the dictionary database 22A according to the touched designated character string, and based on the text information T of the dictionary. After the explanatory information is displayed as a window on the color liquid crystal display screen 17d of the touch panel type color display unit (main screen) 17 (step S123), the process returns to the process from step S110 again and waits for the process for the next operation.

  If it is determined in step S122 that the previously used dictionary content is not a mini-dictionary, the CPU 21 searches for normal dictionary content that is not a mini-dictionary stored in the dictionary database 22A according to the designated character string touched. After the description information based on the text information T of the dictionary is displayed as a window on the color liquid crystal display screen 17d of the touch panel type color display unit (main screen) 17 (step S124), the process returns to step S110 again. Wait for processing for the next operation.

  FIG. 8A shows a touch operation with the thumb of the right hand RH along the character string “Economy” displayed on the touch panel type color display unit (main screen) 17 and the home of the handwriting input unit (sub-screen) 16. The display contents when moving from the “upper” side area, which is the position, to the “middle” side area, which is the shift position, are moved to the thumb of the left hand LH as shown by arrow A21.

  Here, the “middle” area which is the shift position of the transparent touch panel 16t is operated in (A-1) of FIG. 8A, and the color liquid crystal display screen 17d is operated as shown in (A-2). The search result by the mini Japanese dictionary searched from the character string “Economy” is displayed in the dictionary window DW.

  When the user once cancels the touch operation on the transparent touch panel 16t on the handwriting input unit (sub-screen) 16 side with the thumb of the left hand LH from this operation state, the CPU 21 determines that in step S111 through the process of step S110. Then, it is determined whether or not the mini dictionary is being displayed (step S118).

  If it is determined that the mini-dictionary is not being displayed, the CPU 21 shifts to processing according to the operation. However, the description is omitted here because it is not directly related to the present embodiment.

  If it is determined in step S118 that the mini dictionary is being displayed, the CPU 21 erases the dictionary window DW of the mini dictionary that has been displayed on the color liquid crystal display screen 17d of the touch panel type color display unit (main screen) 17 until then. Instead, the contents of the same mini-dictionary are displayed on the color liquid crystal display screen 16d of the handwriting input unit (sub-screen) 16 (step S119).

  Thereafter, the CPU 21 waits for the handwriting input unit (sub-screen) 16 to be operated again based on the output from the transparent touch panel 16t (step S120), and when determining that the transparent touch panel 16t has been operated again, the step S110 is performed. Return to processing from.

  8B temporarily cancels the operation on the handwriting input unit (sub-screen) 16 side from the state of FIG. 8A, and displays the contents of the dictionary window DW on the color liquid crystal display screen 16d instead. The state is illustrated. As shown in (B-1) of FIG. 8B, a part of the contents of the dictionary window DW is displayed in the handwriting input unit (sub-screen) 16. On the one touch panel type color display section (main screen) 17 side, the display of the dictionary window DW so far is canceled as shown in (B-2).

  Further, from the state shown in FIG. 8B, the “lower” side area is touch-operated with the transparent touch panel 16 t of the handwriting input unit (subscreen) 16, and the handwriting input unit (subscreen) 16 side is also displayed. However, it is assumed that a touch operation at one point in the displayed character string or a touch operation along the character string direction is performed.

  In this case, after the processing of steps S110 to S112, it is determined in step S115 that the touch operation is not performed on the “middle” side area of the handwriting input unit (sub-screen) 16, and then the “lower” side area is determined. It is determined whether or not it is a touch operation (step S125).

  Here, the CPU 21 that has determined that the touch operation is in the “lower” area simultaneously touches one point in the character string displayed on the touch panel type color display unit (main screen) 17 or in the character string direction. It is determined whether or not a touch operation has been performed (step S126).

  When it is determined that an operation other than a touch operation at one point in the character string displayed here or a touch operation along the character string direction has been performed, the CPU 21 proceeds to processing according to the operation. The description is omitted here because it is not directly related to the form.

  If it is determined that a touch operation at one point in the character string displayed in step S126 or a touch operation along the character string direction has been performed, the CPU 21 determines that the specified character string subjected to the touch operation exists. A color liquid crystal display screen 17d indicates that the bookmark is set, the page and line of the bookmark position are registered in the bookmark data 22D of the program memory 22 as the corresponding book content bookmark data, and the bookmark position is registered. After identifying and displaying (Step S127), the process returns to the process from Step S110 again to wait for the process for the next operation.

  In FIG. 8C, the “lower” region on the handwriting input unit (sub-screen) 16 side is moved from the state shown in FIG. 8B as indicated by the arrow A22, and touch operation is performed. A case where a touch operation is performed along a character string including the character string “Economy” displayed also on the color display unit (main screen) 17 side is illustrated. As shown in (C-1) of FIG. 8C, a touch operation is performed on the “lower” side area in the handwriting input unit (sub-screen) 16.

  On the one touch panel type color display (main screen) 17 side, the position of the character string “economic” set as a bookmark is slid along the character string direction with the thumb of the right hand RH as shown in (C-2). A touch operation is performed, and the designated character string “Economy” is identified and displayed in a state different from that shown in FIGS. 8A and 8B to express that registration as a bookmark has been made.

  In addition, by simultaneously moving a finger on the handwriting input unit (sub-screen) 16 and the touch-panel color display unit (main screen) 17 and moving them away from each other, the display is enlarged, and the display is reduced by moving in a direction approaching each other. Can be indicated respectively.

  When such a touch operation is performed, it is determined that the touch operation is not performed on the “lower” side area of the handwriting input unit (sub-screen) 16 in the step S125 through the processes of the steps S110 to S112 and S115. It is determined whether the operation is such that the touch position slides on the handwriting input unit (sub-screen) 16 (step S128).

  If it is determined that the touch operation on the handwriting input unit (sub-screen) 16 is not a slide, the CPU 21 proceeds to a process corresponding to the operation, but is not directly related to the present embodiment. The description is omitted here.

  If it is determined in step S128 that the operation is such that the touch position slides on the handwriting input unit (sub-screen) 16, the CPU 21 then moves the region on the “middle” side of the handwriting input unit (sub-screen) 16 to the left or It is determined whether or not the operation is to slide in the right direction (step S129).

  If it is determined that the operation is such that the “middle” side area of the handwriting input unit (sub-screen) 16 is slid in the left-right direction, the CPU 21 next moves the touch-panel color display unit (main screen) 17 side. It is determined whether or not the touch operation is an operation that slides a substantially central region at the height position in the right or left direction as opposed to the handwriting input unit (sub-screen) 16 side (step S130).

  At this time, the touch operation on the touch panel type color display unit (main screen) 17 side was not an operation to slide, or the operation was to slide in the same direction as the handwriting input unit (sub screen) 16 side. In this case, it is assumed that such a touch operation is not set and is invalid, and the process returns to the process from step S110 again without waiting for a process for the next operation without performing any display control.

  If the touch operation on the touch panel type color display unit (main screen) 17 side is an operation to slide in the opposite direction to the handwriting input unit (sub screen) 16 side in step S130, the CPU 21 performs the slide operation. The display screen on the touch-panel color display unit (main screen) 17 is enlarged or reduced depending on the direction, that is, the movement away from each other or the movement toward each other (step S131), and the above-described step again. Returning to the process from S110, the process for the next operation is awaited.

  FIG. 9A shows a case where a slide-type touch operation is performed such that the handwriting input unit (sub-screen) 16 and the touch panel type color display unit (main screen) 17 are separated from each other as indicated by arrows A31 and A32. Show.

  In this case, as shown in (A-1), the handwriting input unit (sub-screen) 16 is operated to slide the “middle” area to the left with the thumb of the left hand LH. In addition, as shown in (A-2), the touch panel type color display unit (main screen) 17 slides to the right with the thumb of the right hand RH at substantially the same height position as the touch panel type color display unit (main screen) 17. To operate.

  By such slide-like touch operations that are separated from each other, the CPU 21 sequentially enlarges the display contents on the touch panel type color display unit (main screen) 17 with an enlargement ratio corresponding to the slide width.

  FIG. 9B shows a case where a sliding touch operation is performed so as to approach each other as indicated by arrows A33 and A34 in the handwriting input unit (sub screen) 16 and the touch panel type color display unit (main screen) 17. Indicates.

  In this case, as shown in (B-1), the handwriting input unit (sub-screen) 16 is operated to slide the “middle” area to the right with the thumb of the left hand LH.

To operate.

  By such a sliding touch operation that approaches each other, the CPU 21 sequentially reduces the display content on the touch panel type color display unit (main screen) 17 with a reduction ratio corresponding to the slide width.

  Furthermore, it is assumed that the display rotation can be instructed by simultaneously moving a finger on the handwriting input unit (sub-screen) 16 and the touch panel type color display unit (main screen) 17 and moving the finger in the opposite vertical direction.

  When such a touch operation is performed, the CPU 21 determines that the touch position is slid on the handwriting input unit (sub-screen) 16 in step S128 through the processes in steps S110 to S112, S115, and S125. In step S129, it is determined that the operation is not an operation of sliding the “middle” side area of the handwriting input unit (sub-screen) 16 in the left or right direction.

  In this case, the CPU 21 then determines whether or not the operation is such that the handwriting input unit (sub-screen) 16 is slid up or down (step S132).

  If it is determined that the operation is not an operation that slides the handwriting input unit (sub-screen) 16 up or down in either direction, the CPU 21 shifts to processing according to the operation. The description is omitted here because it is not directly related.

  If it is determined in step S132 that the operation is such that the handwriting input unit (sub-screen) 16 is slid in either the up or down direction, the CPU 21 next performs the touch panel type color display unit (main screen) 17 side. It is determined whether or not the touch operation is an operation that slides in either direction, up or down, opposite to the handwriting input unit (sub-screen) 16 side (step S133).

  At this time, the touch operation on the touch panel type color display unit (main screen) 17 side was not an operation to slide, or the operation was to slide in the same direction as the handwriting input unit (sub screen) 16 side. In this case, it is assumed that such a touch operation is not set and is invalid, and the process returns to the process from step S110 again without waiting for a process for the next operation without performing any display control.

  If the touch operation on the touch panel type color display unit (main screen) 17 side is an operation to slide downward or upward opposite to the handwriting input unit (sub screen) 16 side in step S132, The CPU 21 rotates the display screen on the touch panel type color display unit (main screen) 17 to the right or left according to the sliding direction (step S134), and then returns to the processing from step S110 again to the next. Wait for processing for the operation.

  In FIG. 10A, a slide-like touch operation is performed such that the handwriting input unit (sub screen) 16 and the touch panel type color display unit (main screen) 17 are rotated to the right as indicated by arrows A41 and A42. Show the case.

  In this case, as shown by (A-1), the handwriting input unit (sub-screen) 16 is operated to slide upward with the thumb of the left hand LH. In addition, as shown in (A-2), the touch panel type color display unit (main screen) 17 is operated to slide downward with the thumb of the right hand RH, contrary to the handwriting input unit (sub screen) 16.

  By such different vertical sliding operations, the CPU 21 sequentially changes the display contents on the touch panel type color display unit (main screen) 17 to the right (clockwise direction) with a rotation angle corresponding to the slide width. Rotate to

  FIG. 10B shows a slide-type touch operation that is rotated to the left as indicated by arrows A43 and A44 in the handwriting input unit (sub-screen) 16 and the touch panel type color display unit (main screen) 17. Indicates the case.

  In this case, as shown in (B-1), the handwriting input unit (sub-screen) 16 is operated to slide downward with the thumb of the left hand LH. In addition, as shown by (B-2), the touch panel type color display unit (main screen) 17 is operated to slide upward with the thumb of the right hand RH, contrary to the handwriting input unit (sub screen) 16.

  With these different vertical sliding operations, the CPU 21 sequentially changes the display contents on the touch panel type color display unit (main screen) 17 with a rotation angle corresponding to the sliding width to the left (counterclockwise direction). ) To rotate.

  In addition to those described above, display on the touch panel type color display unit (main screen) 17 by touch operation on the touch panel type color display unit (main screen) 17 in combination with the touch operation on the handwriting input unit (sub screen) 16 Various settings for controlling the contents to be executed can be realized.

  For example, it is possible to realize display control in which functions are switched by a touch operation on the handwriting input unit (sub screen) 16 side while handwritten character input is performed on the touch panel type color display unit (main screen) 17 side.

  In FIG. 11, after the handwriting input window PW is displayed on the right touch panel type color display unit (main screen) 17 as shown in FIG. 11B, the window PW is displayed by the stylus pen SP held with the right hand RH. A handwritten input unit (sub-screen) 16 holds the electronic dictionary device 10 and holds the electronic dictionary device 10 with a thumb of the left hand LH as shown by an arrow A51 in FIG. (Sub screen) The touch position of 16 is operated so as to slide from the “upper” side region to the “lower” side region as indicated by arrow A51. The handwriting input unit (sub-screen) 16 is set to enable a recognition process for handwritten characters to be quickly executed by a slide operation on the side.

  Also, FIG. 12 shows that an arbitrary character string in the book content displayed on the touch panel type color display unit (main screen) 17 is designated and displayed in reverse so that the analog voice of the character string is displayed in the speech synthesizer 29. The state which produces | generates and reproduces from the speaker 15 is illustrated.
