The search data supplied to the D14 and displayed according to the display data from the CPU 32 is displayed on the LCD 14. The principle of page turning of the electronic catalog 10 configured in this way will be described. First, when the cylinder 18 of the isopoint 16 is rotated in the direction of the dotted arrow 20a or the switch 22a is pushed to advance the screen to the next page, when the forward page turning is performed, the page turning display section showing the state of the page turning is As indicated by an arrow 66 shown in FIG. 6, a hatched area A →
Move along the moving line E in the order of B → C → D. That is, the triangular area A → the quadrangular area B → the pentagonal area C → the quadrangular area D, and the turn-up display section moves, and following this turn-up display section, as shown in FIGS. 7 and 8. The search data on the next page is displayed. That is, in this case, by changing from FIG. 7 to FIG. 8, from the state where the search data of the current page and the next page are displayed in the regions 69a and 69b, respectively, the search data of the current page and the next page are displayed in the regions 69c and 69d, respectively. The search data is displayed. On the other hand, when the cylinder 18 of the isopoint 16 is rotated in the direction of the dotted arrow 20b or the switch 22b is pressed to perform the reverse page turning to return the screen to the previous page, the arrow 68 shown in FIG.
As described above, the turn-over display portion moves in the order of the areas D → C → B → A, and the search data on the previous page is displayed following the turn-up display portion as shown in FIGS. 7 and 8. That is, in this case, by changing from FIG. 8 to FIG.
From the state in which the search data of the current page and the previous page are displayed in the areas 69d and 69c, respectively,
The search data of the current page and the previous page are displayed in b and 69a, respectively.

7 and 8 show the electronic catalog 10 of this embodiment used as, for example, a karaoke search device, with singer names displayed. The calculation of the positions of the vertices that determine the area of the flip-up display portion is performed as follows. First, as a prerequisite, FIGS.
As shown in FIG. 5, each area of the turn-up display portion is represented by five vertices, and their coordinates are (x ₀ , y ₀ ), (x ₁ , y ₁ ),
(X ₂ , y ₂ ), (x ₃ , y ₃ ), and (x ₄ , y ₄ ). The coordinates of the front right corner and the rear left corner of the screen of the LCD 14 are (x _max , y _max ) and (x
_min , y _min ) and the page turning length (x _max −x ₀ ) on the underline of the LCD 14 is L (0 ≦ L ≦
x _max −x _min ).

Further, the angle α = ANGLE (x _max -x
_min −L) / (x _max −x _min ), the turning-over display unit moves along the angle α, that is, the moving line E, and A
NGLE is an initial angle value (constant). Under such a precondition, each coordinate of the triangular area A shown in FIG. 9 is determined according to Equation 1.

[0014]

[Number 1] _{x 0 = x max -L y 0} = y max x 1 = x 2 = x 0 -L · cos (2α) y 1 = y 2 = y 0 -L · sin (2α) x 3 = x ₄ = x _max y ₃ = y ₄ = y _max −L / tan (α) Further, each coordinate of the quadrangular region B shown in FIG.

[0015]

[Number 2] _{x 0 = x max -L y 0} = y max x 1 = x 2 = x 0 -L · cos (2α) y 1 = y 2 = y 0 -L · sin (2α) x 3 = x _min + [(y ₀ −y _min ) ・ sin (2α) +
(X ₀ −x _min ) · cos (2α) −L] / cos (2α) y ₃ = y _min x ₄ = x ₀ + (y ₀ −y _min ) · tan (α) y ₄ = y _min Then, Each coordinate of the pentagonal area C shown in FIG. 11 is determined according to Equation 3.

[0016]

X ₀ = x _max −L y ₀ = y _max x ₁ = x _min y ₁ = y ₀ + (x _min −x ₀ ) · tan (2α) x ₂ = x _min y ₂ = y _min + [(Y ₀ −y _min ) ・ sin (2α) +
_{(X 0 -x min) · cos} (2α) -L ] _{/ sin (2α) x 3 =} x min + _{[(y 0 -y min) · sin} (2α) +
(X ₀ −x _min ) · cos (2α) −L] / cos (2α) y ₃ = y _min x ₄ = x ₀ + (y ₀ −y _min ) · tan (α) y ₄ = y _min Each coordinate of the quadrangular area D shown in FIG.

[0017]

X ₀ = x _max −L y ₀ = y _max x ₁ = x _min y ₁ = y ₀ + (x _min −x ₀ ) · tan (2α) x ₂ = x ₃ = x _min y ₂ = according _{y 3 = y min x 4 =} x 0 + (y 0 -y min) · tan (α) y 4 = y min each formula described above, the coordinates of the turning-up display unit is determined to gradually change The page-turning state can be displayed by the continuous display of the turned-up display portion as shown in FIG.

Next, the turn-up display portion displays two areas which are continuous in time series, that is, a triangular area A shown in FIG.
The case of forward page turning moving from the area to the area A ′ shown in FIG. 14 will be described. Area A for page turning
And a table for writing a turn-up display part such as A ′, a table 2 for writing next page search data such as the area A-E shown in FIG. 15, and a next page search data such as area F. It is executed with reference to Table 3 for writing. Here, each of the tables 1, 2, and 3 is composed of a table 70 as shown in FIG.
The table 70 is composed of 16 bits and has three areas 7.
2, 74 and 76, the format of which is determined as follows.

First, in the area 72, the starting point and the ending point of the x position in the x direction of the filling portion, that is, the range to be processed in each table are defined. Data 10 displayed in area 72
07, 2108, 2508 and 3310 represent the data of the 0th, 1st, 2nd and 3rd lines in order, respectively. The value of each data is divided by 100, and the quotient indicates the starting point of the x position, and the remainder Determines its length, the end of the x position. So if the data is 1007,
Since the quotient is 10 and the remainder is 7, the starting point of the x position is 10 and its length is 7. The range of the x position is 0 to 639. Further, each data 1007, 2108, 2508 and 3310 shown in the area 72 is data set for convenience of explanation.
Then, the data in the area 72 is written in order as long as the rows are continuous, and in the case of jumping over a certain row, the row number is defined using the format of the area 74.

Of the 7 bits from the 9th bit to the 15th bit, the area 74 is represented by "1111110" in which only the 9th bit is 0 and the others are 1 and the 0th bit to the 8th bit. The 9-bit data up to the bit-th bit indicates the line number, and specifies the line number after the jump. The initial value of the line number is 0, and its range is 0 to 399.

Thereafter, as long as the rows are continuous, data such as the area 72 is arranged, and the area 74 is inserted every time the row is skipped. Then, finally, the region 76 is arranged.
In the area 76, data of all 1s is arranged from the 9th bit to the 15th bit, and the data represented by 9 bits from the 0th bit to the 8th bit is displayed in the table 1 in the flip-up display section, the table. In Table 2 and Table 3, the length of the data of each filling portion such as the search data of the next page is shown, and the end point of the filling data is shown.

The above-mentioned areas 72, 74 and 76 form one block, which becomes the data for writing the turn-up display portion and the search data of the next page at a certain time. Therefore, according to the data of one block of the table 70 defined by the format, for example, in the table 1, the area 7 is added to the current row (the 0th row or the row designated by the area 74).
A straight line with a predetermined length is drawn from the start point determined in 2 to indicate the filled part, and then the current line is automatically moved downward by one line to draw the line of the required filled part, and the predetermined turn-up display area is displayed. To form. As shown in FIG. 6, the data of the block forming the predetermined turning-over display portion for each frame corresponds to the turning-over display portion that continuously changes in time series, and the table 70 is set for each frame. Are sequentially written in, and by sequentially reading the data, a turn-up display portion for displaying a page turning state is continuously displayed on the LCD 14. Also, after the flip-up display section is displayed, the search data of the next page is displayed by the tables 2 and 3.

Returning to FIG. 13 to FIG. 15, the case of forward page turning in which the flip-over display section moves from the area A to the area A'will be described. In order to rewrite the area A ′, as shown in FIG. 15, the area A′-E other than the area E which has already been written as the turned-up display area is written in the turned-up display area with reference to Table 1. Next, with respect to the areas A to E that have been written as the flip-up display portion, the search data of the next page is written by referring to Table 2. Then, with respect to the area F in which the search data of the current page is written, the search data of the next page is written by referring to Table 3. The reason for rewriting only the portion other than the area E where the display state does not change is to improve the display speed. By repeating such an operation, as shown in FIG. 6, the turning-over display portion showing the state of page turning is sequentially displayed, and then the search data of the next page is displayed. The search data of the next page is the RAM 50 or the bank RAM 54.
Is written in advance and this search data is displayed on the next page.

On the other hand, in the case of reverse page turning in which the flip-over display unit moves from the region A'to the region A, the display of the flip-up display unit of the region A'-E shown in FIG. Is added. Then, the turning-over display portion is written in the areas A to E, and the search data of the previous page is written in the area F in which the search data of the current page was written.

The operation of the electronic catalog 10 for turning pages according to the above principle will be described with reference to FIG.
First, power is input to the electronic catalog 10, and search data to be displayed on the LCD 14 is displayed by a predetermined operation.
Then, in step S1, it is determined whether or not the isopoint 16, that is, the cylinder 18 is displaced by a predetermined angle or more. If the isopoint 16 is displaced by a predetermined angle or more, the isopoint 16 is displaced in step S3.
Is determined, the process proceeds to step S5 in the case of the dotted arrow 20a direction, that is, forward page turning, to step S7 in the case of the dotted arrow 20b direction, that is, reverse direction page turning, and otherwise. finish. In step S5, in order to perform forward page turning,
Set tables 1, 2, and 3. Then, in step S9, it is determined whether or not the page turning is finished. If the page turning is finished, it is ended. If the page turning is not finished, the table 1 is referred to in step S11. Area A ′ as shown in FIG.
Write the flip-up display. However, unlike the area E shown in FIG. 15, it is not necessary to write in the already-turned-out display portion, so only the area A′-E is newly written. Then, in step S13, the search data of the next page is written in the areas A to E with reference to the table 2. Then, in step S15, referring to Table 3, the search data of the next page is written in the area F. Areas A to E and area F are portions that appear when the page is turned over, and writing the search data to these areas takes time after erasing once.
It is possible to write quickly by overwriting by a process of copying the search data of the corresponding area from the search data of the entire next page stored as an image in M50. The operations of steps S11 to S15 are as follows.
The process is repeated until it is determined in step S9 that the page turning is completed.

On the other hand, if the direction of displacement of the isopoint is the direction of the dotted arrow 16b in the step S3, that is, reverse page turning, the tables 1, 2, and 3 are set so that reverse page turning can be performed in step S7. .. Then, in step S17, it is determined whether or not the page turning is finished. If the page turning is finished, it is finished. If page turning is not finished, the table 1 is referred to in step S19 and the area is determined. Write the flip-over display on A. Note that it is not necessary to additionally write in the turned-up display portion that has already been written like the area E shown in FIG. 15, so only the area A-E is newly written. Then, in step S21, the search data displayed on the previous page is written in the area A'-E by referring to the table 2 and the search data displayed in the previous page is also written in the area F in step S25. Area A'-
Both E and area F are portions that appear when the page is turned over, and writing of search data to these areas is performed in the RAM 5 as in steps S13 and S15.
0 of the previous page search data stored in advance
It can be written by copying the search data in the corresponding area. The operations of steps S19 to S23 are repeated until it is determined in step S17 that the page turning is completed.

In the flow chart shown in FIG. 17,
Although the operation using the isopoint 16 has been described, the same operation can be performed by using switches 22a and 22b or a mouse (not shown) instead of the isopoint 16. Further, if the rotation speed of the isopoint 16 (or mouse) is increased, continuous page turning is possible. That is, as shown in FIG. 18, even when the turning-up display unit is being displayed on the LCD 14, the next turning-up display unit is further displayed. And when the rotation of Isopoint 16 (or mouse) is stopped,
The search data of the last flipped page is displayed on the LCD 14. At this time, the search data displayed on the LCD 14 is the shaded area 78 in the case of forward page turning.
Is the search data for the page, and is the search data for the page in the shaded portion 80 in the case of reverse page turning. Also,
When the switches 22a and 22b are pressed once, one page is turned up, and when the switches are continuously pressed, continuous page turning is possible, and the search data of the last page turned up is displayed on the LCD 14 when the pressing is finished. Displayed in.

The present invention can be used in any device for retrieving desired data by turning pages or changing screens, such as a karaoke retrieval device and a product catalog.
