This touch panel uses an analog transparent resistance film system, and the coordinate value (X, Y) of the pressed position has a coordinate value X in the vertical direction and a coordinate value Y in the horizontal direction as voltage values proportional to the pressed position. The voltage values are detected separately and converted into digital values via an analog / digital conversion circuit (abbreviated as “A / D conversion circuit”) 19, and the CPU 1
Read by 1.

FIG. 2 is a plan view of the display body 16 shown in FIG. The display area 25 of the display means can display information for 20 lines. The scroll bar 21 represents an area of the entire information to be displayed (hereinafter, abbreviated as “entire information”), and displays a scale 22 obtained by dividing the information amount into 10. The numbers displayed in the display area 23 represent the total number of lines of information. That is, the entire information of this embodiment is 50 lines, and one scale represents the information of 5 lines. The slider 24 shows the area of the entire information displayed in the display area 25. Slider 2
Since 4 is displayed in the downward direction from the second scale from the top in FIG. 2, the display area 25 displays the information of the 10th to 20th lines of the entire information. The scroll bar 21 and the slider 24 constitute index display means. Scale 22 in scroll bar 21
The display changes according to the total amount of information, and the amount of information represented by one scale does not change according to the total amount of information. Therefore, if the amount of information is large, the number of scales will be large, and if the amount of information is small, the number of scales will be large. Becomes smaller. Further, when the entire information can be displayed in the display area 25, the scroll bar 21 and the slider 24 are not displayed.

When the shape of the slider 24 represents the same amount of information, the larger the amount of the entire information, the smaller the interval between the scales 21 becomes. Therefore, the slider 24 becomes proportionally smaller and the amount of the entire information can be reduced. For example, since the intervals between the scales 21 are increased, the scales are proportionally increased. In this case, the shape of the slider 24 is set so as not to become smaller than a certain size. This is because if the shape of the slider 24 is smaller than a certain size, it becomes difficult to perform an input operation of touching the slider 24 with a touch pen, and the operability deteriorates.

When it is desired to change the information displayed in the display area 25, the scroll bar 21 is touched with a touch pen. For example, if the first scale 22 in the scroll bar 21 is touched with a touch pen, the slider 24
Is displayed so that the upper side 27 is at the position of the scale 22, and the information corresponding to the display area of the slider 24 is
It is displayed in the display area 25. In addition, the scroll bar 21
When the vicinity of the bottom of the slider is touched with a touch pen and the contact position is set to the top position 27 of the scroll bar 24, the entire slider 24 cannot be displayed. In that case, the bottom position 28 of the slider 24 is changed to the scroll bar. Slider 24 so that it is at the tail position 29 of 21
Is displayed.

To do. When the push button display 32 of the downward arrow is touched with the touch pen, the slider 2
4 moves downward by ⅕ scale, and the screen displayed in the display area 25 is scrolled downward by one line accordingly.

3 and 4 are flow charts showing the processing contents for displaying information on the display 16 shown in FIG. The process is started in step a1.
At step a2, the number of lines is set in a variable A representing the number of lines of the entire information to be displayed. At step a3, it is determined whether the value of the variable A is larger than 20. When the value of the variable A is larger than 20 in step a3, that is, when the entire information is larger than the amount of information (20 lines) that can be displayed in the display area 25 of the display body 16, the process proceeds to step a3.
If the value of the variable A is smaller than 20 in step a3, that is, if the entire information can be displayed in the display area 20, it is not necessary to display the scroll bar 21 and the slider 24, and the process proceeds to step a10.

At step a4, the scale 22 of the scroll bar 21 is displayed. One division of the scale 22 is
Since the setting is made so as to correspond to the information amount for five lines, if the number of dots for one scale is B, then B = the number of dots on the scroll bar / A × 5. Therefore, from the position 33 on the upper side of the scroll bar 21, B-th, 2B-th, 3B
A graduation 22 is displayed at the position of the second dot. At this time, the values of B, 2B, 3B, ... Are set by rounding off the decimal places.

At step a5, the variable C representing the position of the upper side 27 of the slider 24 is set to 0. At step a6, a variable D representing the size of the slider 24 is set.
Since the size of the slider 24 corresponds to the information amount for 20 lines, the variable D is set to 4 × B (the number of dots for 5 lines). In step a7, the variable E indicating which line of the entire information the information currently displayed in the display area 25 corresponds to is set to 0.

At step a8, the slider 24 is displayed based on the variables D and E. In this case, the slider 24 is displayed with a length of 4 scales from the head position 33 of the scroll bar 21.

And 32 are displayed. At step a10, the value 20 of A representing the total number of lines of information is displayed in the display area 23.
In step a11, the information is displayed in the display area 25 from the digit set by the variable E. In this case, the variable E is 0
Since it is set to, the display area 25 is displayed for 20 lines from the beginning of the entire information.

In FIG. 4, in step a12, the variable X is set to -1 and the variable Z is set to 1. Step a
At 13, the tablet 12 is touched by the touch pen, and it is determined whether or not the data representing the position is input. If the data is input, the process proceeds to step a14. If the data is not input, the process waits until it is input.

In steps a14 to a17, if the position touched by the touch pen (hereinafter abbreviated as "touch pen position") is within the scroll bar 21 and outside the slider 24, the process proceeds to step a18. Move. If the contact position with the touch pen is outside the scroll bar 21, the process returns to step a12,
It is in a standby state until input data is input again with the touch pen.

At step a18, the contact position of the touch pen is calculated and set to the variable F. Step a1
At 9, it is determined from the position represented by the variable F whether the slider 24 can be displayed. The determination method is to add 4 × B (the number of dots corresponding to the vertical length of the slider) to the variable F and determine whether the bottom position 28 of the slider 24 is within the scroll bar 21. If the bottom position 28 is in the scroll bar 21, the slider 24 can be displayed in the scroll bar 21.
If the slider 24 can be displayed in the scroll bar 21 in step a19, the process moves to step a20, and the variable F is set to the variable C representing the start position of the information to be displayed, and the position of the variable C is set to the whole information. Then, the number of the line is calculated and the number of lines is set in the variable E. In step a22, the slider 24 is displayed on the scroll bar 21 from the position of the variable C to the length of the variable D (vertical direction). In step a23, information is displayed in the display area 25 for 20 lines from the number of lines represented by the variable E.

At step a19, the slider 24
Is not displayed in the scroll bar 21, in steps a21 to a22, the bottom 28 of the slider 24 is
The slider 24 is displayed so that the position of is aligned with the tail position 29 of the scroll bar 21. That is, in step a21, the variable C is calculated so that the position of the upper side of the slider 24 becomes the position representing the (variable A-19) th line from the beginning of the entire information, and the variable E is set to (variable A-
Set the value of 19). Next, in step a22,
The slider 24 is displayed in the scroll bar from the position of the variable C with the length of the variable D (vertical direction). Step a
In 23, the information is the value of the variable E (variable-19)
20 lines from the line to the last line are displayed in the display area 20.

Next, in the processing of steps a14 to a16, the contact position of the touch pen is changed to the scroll bar 2
If the area is within 1 and within the slider 24, the process proceeds to step a24. At step a24, it is determined whether the variable X is -1. If the value of the variable X is -1,
It is shown that the inside of the slider 24 is touched with the touch pen for the first time, and the process proceeds to step a25. In step a25, it is calculated which position in the scroll bar 21 the contact position with the touch pen is, and the variable X is set, and step a1
Return to 3. The processes of steps a13 to a16 are executed again, and the slider 24 is continuously operated by the touch pen.
If the inside is in contact, the process proceeds to step a24. In step a24, the value of the contact position of the touch pen is set in the variable X in the previous process, and the value of X is different from -1, so the process moves to step a26.

At step a26, the current contact position of the touch pen is set to the variable Y, and the process proceeds to step a27. At step a27, the variable Y is subtracted from the value of the variable X, the value is set to the variable Z, and the value of the variable Y is set to the variable X. That is, it is calculated how much the current touch position of the touch pen has moved since the previous process, the value is set to the variable Z, and the value of the current touch position is set to the variable X. In step a28, it is calculated whether or not the value of the variable Z, which is the moving distance of the touch position of the touch pen, is zero. If the variable Z is 0, the contact position of the touch pen at the previous time has not moved since the previous process,
The process is not performed, the process returns to step a13, and the processes of steps a13 to a16 and steps a24 to a28 are repeated until the contact position of the touch pen moves.

If the variable Z is not 0 in step a28, it means that the current touch position of the touch pen has been moved since the previous process, and step a2
Go to 9. In step a29, it is determined whether the value of the variable Z is positive. When the value of the variable Z is a positive value, it indicates that the contact position of the touch pen is moving upward in the slider 24, and step a3
Move to 0.

At step a30, the variable Z representing the moving distance is subtracted from the variable C representing the upper side position 27 of the slider 24 to calculate the position of the upper side position 27 of the slider 24, and the upper side position 27 of the slider 24 is changed to the scroll bar. Two
It is calculated whether or not it falls within 1.

At step a30, the slider 24
When the upper side position 27 is within the scroll bar 21, the process proceeds to step a31, and the value obtained by subtracting the value of the variable Z from the value of the variable C is set to the variable C as the upper side 27 of the current slider 21. At step a32, it is calculated which line the position of the scroll bar 21 represented by the variable C corresponds to in the entire amount of information, and the variable E is set. At step a33, the slider 24 is displayed from the value of the variable C to the length of the variable D (vertical direction). In step a34, information is displayed in the display area 25 for 20 lines from the number of lines represented by the variable E.

In step a30, the slider 24
If the upper side position 27 does not fit within the scroll bar 21, the process proceeds to step a35. In step a35,
The upper side position 27 of the slider 24 currently displayed is
It is determined whether or not it is at the head position 33 of the slider. If it is at the head position 33, there is no need to perform any processing. Therefore, the process returns to step a13, and if not at the head position 33, the process proceeds to step a36. In step a36, the variable C representing the upper side position of the slider 24 is set to 0, the above-described steps a32 to a34 are performed, and the slider 24 is displayed with the length of the variable D from the top position 33 of the scroll bar 21, In the display area 25, 2 from the first line of the whole information.
