The CPU (FIG. 2) uses the Web browser of the storage unit 12 to display the Web page 31 on the display screen 30 of the display unit 16 (FIG. 2) as shown in FIG. When a predetermined click operation is performed on the display screen 30 or when a predetermined operation is performed with a keyboard (not shown), the Web browser 20 causes the display screen 30 to be displayed as shown in FIG. The controller panel 32 is displayed together with the web page (step 100 in FIG. 4).

  Here, the controller panel 32 is displayed outside the display area of the Web page 31 on the display screen 30. However, when the Web page 31 is displayed on the entire display screen 30, it overlaps the Web page 31. The controller panel 32 is displayed.

Here, the controller panel 32 will be described with reference to FIG.
FIG. 7 is a diagram showing a specific example of the controller panel 32 displayed on the display screen 30, in which 33 is a display size change operation unit, 34 is a continuous change operation unit, 34 a is a slider, 34 b is a scale of magnification, 35a is a "reduction" button, 35b is an "enlargement" button, 35c is a "standard size" button, 36 is an enlargement ratio display section, 37 is a screen color change operation section, 38 is a "black and white" display button, and 39 is "black and white inversion""Displaybutton", 40 is a "reverse color" display button, 41 is a "return color" button, 38a to 40a are icons, 38b to 40b are operation display marks, and 42 is a "help" button.

  In the figure, a controller panel 32 has the same configuration as that of a remote control panel used in a television, video, etc., and is operated by a cursor (not shown). The operation can be performed.

  The controller panel 32 has a display size change operation unit 33 that can change the screen size of the Web page 31 displayed on the display screen 30 and a screen color change that can change the color (including monochrome) of the screen. An operation unit 37 is included.

  In the display size change operation unit 33, a continuous change operation unit 34 capable of continuously changing the screen size of the Web page 31, a “reduction” button 35a and an “enlargement” button 35b for changing discontinuously, A “standard size” button 35 c for returning to the standard screen size is provided. The continuous change operation unit 34 is provided with an enlargement scale 34b and a slider 34a. The enlargement scale 34b is assigned, for example, 50% to 300%, and the enlargement ratio is within this range. Can be changed continuously.

  This enlargement ratio can be changed by moving the slider 34a. That is, when the mouse is operated to touch (touch) the slider 34a and drag in the direction (right direction) indicated by the triangular mark on the slider 34a, the slider 34a moves to the right and expands. The rate increases. Further, when the cursor is touched on the slider 34a and dragged in the direction (left direction) indicated by the leftward mark of the triangle mark, the slider 34a moves leftward and the enlargement ratio decreases. Then, the magnification rate is changed by moving the slider 34a as described above, and the magnification rate displayed on the magnification rate display unit 36 is also changed. In order to set the desired enlargement ratio, the drag may be released when the slider 34a reaches the position of the desired enlargement ratio on the scale 34b.

  When the cursor touches the slider 34a, for example, the slider 34a is displayed in blue (may be in a state where a shadow is displayed in blue), and the cursor touches the effective area of the slide 34a. In other words, it is shown that the dragging (operation of the slider 34a) is possible, and this color is erased as the dragging starts.

  Further, when the “reduction” button 35a is touched with the cursor, the “reduction” button 35a is displayed in a state where, for example, a blue shadow is generated, and the cursor touches the effective area of the “reduction” button 35a. When a click operation is performed in such a state, the enlargement rate is sequentially reduced by a predetermined amount every time a predetermined time elapses from the currently set enlargement rate. At the same time, the slider 34a moves in the direction in which the enlargement ratio decreases, and the enlargement ratio displayed on the enlargement ratio display section 36 also decreases. At this time, the “reduction” button 35a is depressed and displayed in place of the shadow display state, indicating that the “reduction” button 35a is functioning.

  Further, when the “enlarge” button 35b is touched with the cursor, the “enlarge” button 35b is displayed in a state where, for example, a blue shadow is generated, and the cursor touches the effective area of the “enlarge” button 35b. When a click operation is performed in such a state, the enlargement rate is sequentially increased by a predetermined amount from the currently set enlargement rate every elapse of a predetermined time. At the same time, the slider 34a moves in the direction in which the enlargement ratio increases, and the enlargement ratio displayed on the enlargement ratio display section 36 also increases. At this time, the “enlarge” button 35b is displayed in a depressed state in place of the shadow display state described above, indicating that the “enlarge” button 35b is functioning.

  Accordingly, the slider 34a is always at the position of the current enlargement factor, and the enlargement factor display unit 36 always displays the current enlargement factor. Further, the “standard size” button 35c is touched with the cursor (in this case, the “standard size” button 35c is displayed as if a blue shadow is generated, and the cursor touches the effective area of the “standard size” button 35c. When the click operation is performed in this state (the “standard size” button 35c is in a display state in which the blue shadow disappears and becomes depressed), the enlargement ratio is 100% (that is, the default value). ). At this time, the slider 34a is at a position where the enlargement ratio is 100%, and the enlargement ratio display portion 36 displays the enlargement ratio 100%.

  In this way, with the slider 34a, the “reduction” button 35a, the “enlargement” button 35b, and the “standard size” button 35c, when the cursor is touched, a shadow that is easy to see even for people with weak colors, for example, blue as described above, is used. The viewer can easily recognize that these have been touched.

  In the screen color changing operation unit 37, icons 38a, 39a, 40a representing respective functions are provided for each of the “black and white” display button 38, the “black / white reversal” display button 39, and the “color reversal” display button 40. , Operation display marks 38b, 39b, and 40b indicating that they are operated (in this case, they are triangular, but may be other shapes). The functions of these display buttons 38 to 40 can also be estimated by these icons 38a, 39a, and 40a.

  When the “monochrome” display button 38 is clicked, the entire monochrome web page 31 that has been displayed in black and white inversion is returned to the original monochrome display. In this case, when the “black and white” display button 38 is touched with the cursor, the “black and white” display button 38 is displayed as if, for example, a blue shadow is generated, as in the above-described operation means in the display size changing operation unit 33. In this state, it is indicated that the cursor is touching the effective area of the “black and white” display button 38. When a click operation is performed in such a state, the “black and white” display button 38 is pressed and displayed as if it is depressed, and the monochrome web page 31 that has been displayed in black and white inversion is returned to the original monochrome display. Thus, in the monochrome display state, the operation display mark 38b is lit in a predetermined color (for example, orange) that is different from the above-described shadow color and is easy to see even for those with weak colors. The state in which the operation display mark 38b is lit indicates that the currently displayed web page 31 is originally displayed in monochrome.

  When the monochrome display reverse display button 39 is clicked, the entire monochrome web page 31 is changed from a monochrome display to a display state reversed from black to white. Also in this case, as in the above-described operation units in the display size change operation unit 33, when the monochrome display reverse display button 39 is touched with a cursor, for example, a blue shadow appears on the monochrome display reverse display button 39. In the displayed state, it is indicated that the cursor is touching the effective area of the monochrome display reverse display button 39. When a click operation is performed in such a state, the monochrome display reverse display button 39 is depressed and displayed as if it was depressed, and the monochrome Web page 31 is displayed in a state where the monochrome is reversed. As described above, when the display state is reversed in black and white, the operation display mark 39b is lit in a predetermined color (for example, orange) which is different from the above-mentioned shadow color and is easy to see even for the color weak. The state in which the operation display mark 39b is lit indicates that the currently displayed monochrome web page 31 is displayed with black and white reversed.

  When the Web page 31 is in monochrome display (that is, a display form in which the character portion is displayed in black and the background portion is displayed in white when the area where characters are displayed is taken as an example), the “monochrome” display button 38 is used. When the operation display mark 38b is colored and lit, and the Web page 31 is displayed in black and white inversion, the operation display mark 39b on the “black and white reversal” display button 39 is colored and lit. Therefore, for example, when the “black and white reversal” display button 39 is clicked and the web page 31 is displayed in black and white reversal, the operation display mark 39 b is colored and lit, and the other display buttons of the screen color change operation unit 37 are clicked. Until the display is changed to another display mode, the operation display mark 39b continues to be colored.

  By the way, when the monochrome web page 31 displayed on the display screen 30 is viewed, whether the web page 31 is currently displayed in the original monochrome state, or is displayed in a state in which the monochrome page is reversed, It is difficult to judge. In the first embodiment, the operation display marks 38b and 39b are provided on the “black and white” display button 38 and the “black and white reversal” display button 39, respectively, so that the original black and white display state is changed from these states. Thus, it is possible to easily determine whether the display state is reversed in black and white.

  When the displayed web page 31 is a color screen (not including a monochrome screen), the “color inversion” display button 40 is clicked to change the color of the entire web page 31 to, for example, a complementary color. (This is hereinafter referred to as color reversal. Note that this color reversal does not necessarily have to be a complementary color. For each color, a color to be changed is determined in advance, and “color reversal” is determined. When the display button 40 is touched with a cursor, the display of each part may be changed to a corresponding color (this process is also called color reversal). Also in this case, when the “color inversion” display button 40 is touched with the cursor, for example, a blue shadow is displayed on the “color inversion” display button 40, as in the above-described operation means in the display size change operation unit 33. It is displayed as it appears, indicating that the cursor is touching the effective area of the “color inversion” display button 40. When a click operation is performed in such a state, the “color reversal” display button 40 is depressed and displayed as being depressed, and the color web page 31 is displayed in a state where the color is reversed. In this way, when the color inversion display state is set, the operation display mark 40b is lit in a predetermined color (for example, orange) that is different from the shadow color and easy to see even for those with weak colors. The state in which the operation display mark 40b is lit indicates that the currently displayed color web page 31 is displayed with its color reversed. In order to return to the original color display, a “reset color” button 41 may be clicked.

  When the color web page 31 displayed on the display screen 30 is viewed, it is difficult to determine whether the web page 31 is currently displayed in its original color tone or is displayed with its color inverted. . In the first embodiment, as described above, the operation display mark 40b is provided on the “color inversion” display button 40, and it is easy to determine whether the display state is the original color tone or the display state in which the color is inverted. It makes it possible to judge.

  As described above, the control panel 32 has a configuration similar to that of a remote control panel of other home appliances such as a television and a video, and is operated with a cursor. Since each operation means can be operated in the same manner as each operation means on the remote control, it is similar to the remote control of other household appliances that are generally used by ordinary people. The controller panel 32 can be operated with a sense, which makes it easy for the elderly, visually impaired, and infants to operate.

  The controller panel 32 is also provided with a “help” button 42. By touching this button with a cursor, an explanation screen (not shown) regarding the controller panel 32 is displayed by a window at a position different from the controller panel. ) Is displayed.

  Hereinafter, the controller panel 32 will be described with reference to FIG. Further, the click and drag operations on the display buttons and sliders as described above will be simply referred to below as operating the display buttons and sliders.

  Returning to FIG. 4, as shown in FIG. 6, the controller panel 32 is also displayed on the display screen 30 (step 100). When the slider 34a of the display size changing operation unit 33 of the control panel 32 is operated (step 100). 101, 102), an enlargement ratio corresponding to the position of the slider 34a is set (step 103), and the Web page (target HTML) 31 is displayed at this enlargement ratio (step 108).

  FIG. 8 shows a state where the enlarged display is performed at an enlargement rate of 250%, and FIG. 9 shows a state where the Web page 31 is reduced and displayed at an enlargement rate of 70%.

  Here, the enlargement / reduction display with the enlargement ratio = α is the enlargement / reduction of both the horizontal and vertical widths of the Web page 31 by α% with the upper left corner of the Web page 31 (the position of the point P in FIG. 8) as the reference position. To do. In addition, the enlarged display means that the horizontal width and the vertical width are enlarged and displayed with respect to the reference size (the screen size when the enlargement rate is 100% and display is started). It means that the width and height are reduced and displayed with respect to the reference size. Therefore, these enlarged display and reduced display are displayed by operating the slider 34a and the “enlarge” button 35b to increase the enlargement rate from the current enlargement rate, and operating the slider 34a and the “reduced” button 35a. This means differently from displaying the current enlargement rate by reducing the enlargement rate.

  In the enlarged display state shown in FIG. 8, the web page 31 can be scrolled vertically and horizontally by operating the scroll bars 33a and 33b as usual. Any area can be browsed.

  When the “reduction” button 35b is operated in the display size change operation unit 33 of the control panel 31 (step 104 in FIG. 4), the enlargement rate is decreased from the current enlargement rate by a predetermined value, for example, 5%. (Step 106 in FIG. 4), the Web page 301 is displayed at the enlargement ratio (Step 108 in FIG. 4). Then, the process returns to step 101. As long as the “reduction” button 35b is operated, the operations of steps 101, 102, 104, 106, and 108 are repeated every predetermined time. The enlargement ratio decreases by a value of 5 (in the above case, 5%).

  This is the same when the “enlarge” button 35b is operated (steps 104 and 107 in FIG. 4), and the operations of steps 101, 102, 104, 107, and 108 are repeated every predetermined time. Thus, the enlargement rate increases by a predetermined value (in the above case, 5%) every predetermined time.

  When the “standard size” button 35c is operated in the display state shown in FIG. 8 or FIG. 9 (step 104 in FIG. 4), the screen returns to the display state of the Web page 31 having the original screen size at the enlargement ratio 100 shown in FIG. (Steps 105 and 108).

  Next, when the displayed Web page 31 is a monochrome screen, one of the standard size display state shown in FIG. 6, the enlarged display state shown in FIG. 8, and the reduced display state shown in FIG. 9, for example, FIG. When the “black / white reversal” display button 39 is operated (step 109 in FIG. 4) in the screen color change operation unit 37 of the control panel 31 (step 101 in FIG. 4) in the display state shown in FIG. 10, as shown in FIG. On the monochrome screen, the web page 31 is displayed in a display form in which the white part is inverted to black and the black part is inverted to white. If the monochrome screen has black and white shading, the density ratio is inverted (step 111 in FIG. 4). When the web page 31 is displayed in black and white in this way, when the “monochrome” display button 38 is operated in the screen color change operation unit 37 of the control panel 31 (step 101 in FIG. 4) (in FIG. 4). Step 109), as shown in FIG. 6, the Web page 31 is displayed in the original monochrome display (Step 110 in FIG. 4).

  In this way, when the monochrome-displayed web page 31 is displayed, it can be displayed by reversing it in black and white, or the web page 31 displayed in monochrome reversal can be returned to the monochrome display. Therefore, in the monochrome display, if the web page 31 is difficult to see because the white background is too dazzling, the web page 31 can be displayed by the simple operation of the “black / white reversal” display button 39 on the controller panel 32 as described above. It can be displayed in monochrome reverse display. Further, if the web page 31 by the monochrome reversal display is difficult to see in this display form, the web page 31 can be generated by the simple operation of the “monochrome” display button 38 on the controller panel 32 as described above. Monochrome display state.

  When the displayed Web page 31 is a color screen, one of the standard size display state shown in FIG. 6, the enlarged display state shown in FIG. 8, and the reduced display state shown in FIG. 9, for example, as shown in FIG. When the “color inversion” display button 40 is operated in the screen color change operation unit 37 of the control panel 31 (step 101 in FIG. 4) in the display state (step 109 in FIG. 4), as shown in FIG. The web page 31 is displayed in a display form in which the color tone is inverted (for example, a complementary color) (step 112 in FIG. 4). When the web page 31 is displayed in reverse color tone in this way, when the “Reset Color” button 41 is operated in the screen color change operation section 37 of the control panel 31 (step 101 in FIG. 4) ( In step 109 of FIG. 4, the original color web page 31 shown in FIG. 6 is displayed (step 113 of FIG. 4).

  In this way, when the web page 31 is displayed in color, for example, when the screen is difficult to see due to the background color or the like, a simple operation of the “reverse color” display button 40 on the controller panel 32 allows The web page 31 that is easy to view is displayed by reversing the color tone.

A process for changing the screen color of the Web page 31 is performed (step 205).

That is, as in the first embodiment, when the “monochrome” display button 38 is selected by the function selection operation unit 53, the web page 31 is displayed on a monochrome screen as shown in FIG. When the “reverse black and white” display button 39 is selected, the web page 31 is displayed on a screen in which black and white are reversed with respect to the screen of the web page 31 shown in FIG. 14 as shown in FIG. Further, when the web page 31 shown in FIG. 14 is displayed in color, when the “reverse color display” button 40 is selected, as shown in FIG. 17, the web page is displayed as in the first embodiment. For example, the color of the entire 31 is inverted to a predetermined color such as a complementary color. When the “reset color” button 41 is selected, the color display of the web page 31 is restored.

  Thus, the setting state by the screen color change operation unit 37 is held until the next operation (step 204) of the controller panel 51 or the click operation (step 207) of the display / non-display switch area 50 is performed. The web page 31 is held in the set display state (that is, the determination processes in steps 204 and 207 are repeated).

  As described above, when the web page 31 is displayed in black and white by the operation of the controller panel 51 (FIG. 14), black and white reversed display (FIG. 16), or color tone reversed (FIG. 17). Is displayed on the setting information display unit 58 in the display size change operation unit 52 of the controller panel 51.

  Next, on the display screen 30 of the display state shown in FIG. 17 (step 203 in FIG. 12), when the “reading” button 55 is clicked on the function selection operation unit 53 of the controller panel 51 (step 204 in FIG. 12), The display screen 30 is in the display state shown in FIG. In this display screen 30, as in the display screen 30 shown in FIG. 17, a web page 31, a display / non-display switch area 50, and a controller panel 51 are displayed. Instead of 37, a voice reading operation unit 60 is provided. By operating the operation unit 60, the text on the Web page 31 is read out and output as synthesized speech, so that a visually impaired person, an elderly person, an infant, and the like can understand the contents of the Web page 31. I have to.

  FIG. 19 is an enlarged view of the controller panel 51 displayed on the display screen 30 shown in FIG. 18, in which 60 is a voice reading operation unit, 61 is an “ON” button, 62 is an “OFF” button, and 61 a and 62 a are operations. A display mark, 63 is a “read next” button, 64 is a “read next” button, 65 is a “pause” button 6, 66 is a “volume setting” button, 67 is a “read speed setting” button, and 66a is A volume display section 67a is a reading speed display section, and parts corresponding to those in the previous drawings are given the same reference numerals.

  In the figure, an “ON” button 61 is used to read out the Web page 31. When this button is clicked, reading out of the Web page 31 is started. Further, when the “OFF” button 62 is clicked, the reading of the Web page 31 is stopped. The “ON” button 61 and the “OFF” button 62 are also displayed as depressed when they are selected by clicking, and the operation display marks 61a and 62a are lit in colors that are easy to see even for those with weak colors. .

  The “read next” button 63 and the “read next” button 64 are for changing the reading position. When the “read previous” button 63 is clicked, the Web page 31 is clicked for each click operation. The reading position of the sentence is moved forward from the current reading position by one paragraph unit of the sentence, and each time the “read next” button 64 is clicked, In addition, the reading position of the text on the Web page 31 moves backward from the current reading position in units of one paragraph of the text.

  The “volume setting” button 66 is for adjusting the volume of the voice when reading the text on the Web page 31, and this volume can be adjusted in five levels of 1 to 5. The “volume setting” button 66 is provided with a “+” operation unit and a “−” operation unit. The “+” operation unit increases the volume by one step each time a click operation is performed. Then, the “−” operation unit lowers the volume by one step each time the portion is clicked. The currently set volume is displayed on the volume display section 66a.

  The “reading speed setting” button 67 is for adjusting the reading speed of the text on the Web page 31, and this speed can also be adjusted in five stages of 1 to 5. The “reading speed setting” button 67 is also provided with a “+” operation unit and a “−” operation unit, and the “+” operation unit reads one step at a time each time a click operation is performed. The speed is increased, and the “−” operation unit decreases the reading speed by one step each time the portion is clicked. The currently set reading speed is displayed on the reading speed display section 67a.

  By operating the voice reading operation unit 60 described above, the voice reading of the Web page 31 can be performed. Next, the voice reading operation will be described based on the flowchart shown in FIG. The reading operation according to FIG. 20 is performed by clicking the “reading” button 55 on the function selection operation unit 53 of the controller panel 51 or by operating the voice reading operation unit 60 of the controller panel 51 (FIG. 20). 12 of step 204 “reading”) is executed.

  This voice reading operation is performed by operating the voice reading operation unit 60 of the controller panel 51 on the display screen 30 shown in FIG. 18. The operation of the controller panel 51 is also shown in FIG. And explained.

  When the “OFF” button 62 is selected in the voice reading operation unit 60 of the controller panel 51 (step 300 in FIG. 20), the “reading” button 55 in the function selection operation unit 53 of the controller panel 51 is selected. When the display state shown in FIG. 18 is reached, the “ON” button 61 is normally selected in order to simplify the operation), and the process returns to step 204 in FIG. Until the operation is performed, steps 204 and 207 in FIG. 12 are repeated while the display state shown in FIG. 18 is maintained on the display screen 30.

  When the “ON” button 61 is selected or selected (step 300 in FIG. 19) in the voice reading operation unit 60 of the controller panel 51, the reading start position of the web page 31 is determined (in FIG. 20). Step 301. When the “read before” button 63 and the “read next” button 64 are not clicked, the title of the Web page 31 is determined, and the reading position of the Web page 31 from this start position is determined (FIG. 20). Step 302). Then, the synthesized speech data for the sentence at the determined position is read from the storage unit 12 (FIG. 2), and after steps 306 and 307, the volume and the reading speed set at this time (that is, the initial setting) are read. Outputs synthesized speech. Then, the process proceeds to step 302 through step 313, the next reading position of the text on the Web page 31 is determined, and reading is performed in the same manner.

In this manner, when the voice reading operation unit 60 is not operated, the voice reading is performed from the start position of the Web page 31 at the initial volume and the reading speed. At this time, in the Web page 31 displayed on the display screen 30, as shown in FIG. 21 , the portion 70 that has been read out is reversed in black and white or in color (in this case, the reading is performed from the middle). ) So that the part being read out can be easily understood. When the Web page 31 is being read out in this way, the setting information display unit 58 in the display size change operation unit 52 of the controller panel 51 performs a voice reading function such as “voice ON”. Information indicating that is being executed is displayed.

  Returning to FIG. 20, when the read-out state is to be read out again in this reading-out state, the user clicks the “read ahead” button 63 of the voice-reading operation unit 60 (step 306 in FIG. 20). . Each time this click operation is performed, the position to be read back moves forward by one paragraph of the sentence on the Web page 31, and the position to read the sentence is determined from that position (step 304 in FIG. 20). The synthesized voice data is taken from the storage unit 12 (FIG. 2) and outputted as a voice (step 312 in FIG. 20). After that, the voice is read out from that position.

  For example, in the Web page 31 shown in FIG. 18, when the “read” button 63 is click-operated when a paragraph starting with “A person who joins the long-term care insurance system” is read aloud, the previous page is displayed. Moving to the reading of “Person who takes care insurance”, which is a paragraph, and when the “read before” button 63 is clicked, the sentence starting with “The care insurance system is” in the previous paragraph Move on to reading aloud.

  In addition, when the web page 31 is in a reading state and the user wants to skip the middle and read out later, the user clicks the “read next” button 64 of the voice reading operation unit 60 (see FIG. 20). Step 306). Each time this click operation is performed, the reading position is moved backward by one paragraph of the sentence on the Web page 31, and the reading position of the sentence is determined from that position (step 304 in FIG. 20). The synthesized voice data of the sentence is taken from the storage unit 12 (FIG. 2) and outputted as a voice (step 312 in FIG. 20). After that, the voice is read out from that position.

  For example, in the Web page 31 shown in FIG. 18, when the “read next” button 64 is click-operated while reading a paragraph beginning with “A person who joins the long-term care insurance system” is read out, When the text that starts with “What is the first insured person” begins to be read aloud and the “call ahead” button 64 is clicked, ““ No. With "No. 2 insured person", we move to reading out sentences starting with "."

  In this way, by clicking on the “read previous” button 63 or the “next read” button 64, the position to be read out can be determined as appropriate.

  In addition, when the Web page 31 is being read out, the volume of the voice reading out can be adjusted by operating the “volume setting” button 66 with a clock. When the “−” portion of the “volume setting” button 66 is operated by a clock (step 307 in FIG. 20), the volume decreases by one step for each operation (step 308 in FIG. 20), and the synthesized voice to be output is output. Is getting lower. When the “+” portion of the “volume setting” button 66 is operated by a clock (step 307 in FIG. 20), the volume increases by one level for each operation (step 309 in FIG. 20) and is output. The synthesized speech gets higher. The volume display section 66a displays the volume at that time.

  Further, by operating the “reading speed setting” button 67 while the Web page 31 is being read out, the speed at which the voice is read out can be adjusted. When the “−” portion of the “reading speed setting” button 67 is operated by a clock (step 307 in FIG. 20), the reading speed decreases by one step for each operation (step 310 in FIG. 20), and output is performed. The speed of synthesized speech is getting lower. When the “+” portion of the “reading speed setting” button 67 is clocked (step 307 in FIG. 20), the reading speed increases by one step for each operation (step 311 in FIG. 20). , The synthesized speech that is output becomes faster.

  In this way, the volume and speed of reading the web page 31 can be adjusted as appropriate. Although the volume and the reading speed can be adjusted in five stages, it is needless to say that the present invention is not limited to this.

  When the “pause” button 65 of the voice reading operation unit 60 is clicked during such a voice reading of the web page 31, the operation stops during the operations of steps 302 to 312 in FIG. 20, and the voice reading is temporarily stopped. Stop. When the “pause” button 65 is clicked again, the pause is released and the speech is read out again.

  When the voice reading is finished, the “OFF” button 62 of the voice reading operation unit 60 is clicked. As a result, the voice reading operation ends (step 313 in FIG. 20), the process returns to step 204 in FIG. 12, and the determination operations in steps 204 and 207 are repeated in the display state shown in FIG. Of course, at this time, when the “ON” button 61 in the voice reading operation unit 60 of the controller panel 51 is clicked, the operation shown in FIG. 20 is performed, and the Web page 31 is read aloud as described above. Done.

  When the Web page 31 is read aloud, as shown in FIG. 21, the portion 70 where the text is read out may be reversed in black and white, and the portion may be enlarged and displayed with a balloon 71. Thereby, the reading-out part 70 can also be easily recognized visually.

  Even when the Web page 31 is read aloud, the display size change operation unit 51 on the controller panel 51 can be operated. FIG. 22 shows the case where the Web page 31 is enlarged and displayed at an enlargement rate of 194%, and FIG. 23 shows the case where it is reduced and displayed at an enlargement rate of 52%. In these cases, the respective enlargement ratios are displayed on the setting information display unit 58. 22 and 23, the “reading” button 55 is selected in the function selection operation unit 53 of the controller panel 51. However, since the “OFF” button 62 is selected in the voice reading operation unit 60, When the Web page 31 is not read aloud, but the “ON” button 61 is selected and the Web page 31 is being read aloud, the setting information display unit 58 displays information such as “Voice ON”. Will also be displayed.

  For example, when the “phonetic” button 56 (FIG. 15) is clicked on the function selection operation unit 53 of the controller panel 51 in the display state of the display screen 30 shown in FIG. 14 or FIG. 18, the display screen is displayed as shown in FIG. 30, the controller panel 51 is displayed together with the Web page 31 and the function setting area 57 in place of the furigana (ruby) operation unit 72.

  When the controller panel 51 is shown in an enlarged manner, as shown in FIG. 25, the phonetic (ruby) operation unit 72 has a “Romaji” button 73 having an operation display mark 73a and a “Roman character” having an operation display mark 74a. "Button 74 and" undo "button 75 are provided. When these buttons 72 to 73 are clicked, the buttons 72 to 73 are depressed and displayed as being depressed, and the operation display marks 73a and 74a are lit in a color that is easy to see even for those with weak colors, like the previous operation display marks. .

  By operating the phonetic “Rubi” operation unit 72 of the controller panel 51, the text on the Web page is displayed with the phonetic attached. The operation will be described with reference to the flowchart shown in FIG. The controller panel 51 at that time will be described with reference to FIG.

  Now, the determination processing in steps 204 and 207 of FIG. 12 is repeated, and the “phonetic” button 56 (FIG. 15) on the function selection operation unit 53 of the controller panel 51 in the display state of the display screen 30 shown in FIG. 14 or FIG. When the button is clicked (step 204 in FIG. 12), the display screen 30 is displayed as shown in FIG. 24, and the controller panel 51 having the furigana (ruby) operation unit 72 is displayed. At the same time, the operation of the flowchart shown in FIG. 26 is started. If the furigana (ruby) operation unit 72 is not operated (step 400 in FIG. 26), the process returns to step 204 in FIG. 12, and no furigana is added. The determination operation in steps 204 and 207 is repeated in the display state shown in FIG.

  Thereafter, when the “Hiragana” button 73 (FIG. 25) on the furigana (ruby) operation unit 72 of the controller panel 51 is clicked, the operation shown in FIG. 26 starts again, and the “Hiragana” button 73 is clicked. Is detected (step 400 in FIG. 26), and hiragana ruby addition processing is performed (step 401 in FIG. 26). As a result, as shown in FIG. 24, the Web page 31 is displayed with the furigana 76 by hiragana attached to the sentence.

  Further, when the “Romaji” button 74 (FIG. 25) is clicked on the furigana (ruby) operation unit 72 of the controller panel 51, the click operation of the “Romaji” button 74 is detected (step 400 in FIG. 26). ) Romaji ruby addition processing is performed (step 402 in FIG. 26). As a result, as shown in FIG. 27, the Web page 31 is displayed with the furigana 77 in Roman letters attached to the sentence.

  Further, in the display state with furigana 76 and 77 as shown in FIG. 24 or 27, the “return” button 75 (FIG. 25) on the furigana (ruby) operation unit 72 of the controller panel 51 is clicked. Then, the attached furigana is removed, and the web page 31 without the furigana is displayed. In this case, the controller panel 51 is displayed with a phonetic (ruby) operation unit 72 and is hand-woven, and the determination operation in steps 204 and 207 in FIG. 12 is repeated to wait for the next operation of the controller panel 51.
