[0022]

The input panel of the conventional coordinate input device is flat. Therefore, when the cursor is moved to a desired position on the display board, it is necessary to visually confirm the center position of the panel, estimate the azimuth angle and the distance from the center, and press the flat panel input panel.

That is, the conventional coordinate input device has a problem that the operability is poor because the so-called blind operation, that is, the operation is performed while looking at only the screen of the display panel without looking at the input panel.

In the conventional coordinate input device, the input panel is flat. Therefore, when a wide operation area is required, the coordinate input device becomes large in size.
The present invention was created in view of the above points, and an object thereof is to provide a small-sized coordinate input device capable of performing a blind operation.

[0025]

In order to achieve the above object, the present invention is to push the surface of an input panel to move a cursor on a display panel of an information processing apparatus, and to process coordinates indicated by the cursor. In the coordinate input device to input to the device,
As illustrated in FIG. 1, a conductive film 12 is formed on the upper surface of a convex insulating film 11 whose center is the apex P-1, and a pair of feeding electrodes opposed to the front and rear side edges of the insulating film 11. 1
The first sheet 10 having 3,14 and the conductive film 22 is formed on the lower surface of the other convex insulating film 21 having the center at the apex P-1, and the conductive film 22 is formed on the left and right side edges of the insulating film 21. And a second sheet 20 having a pair of opposing power supply electrodes 23, 24,
It is assumed that the convex surface input panel 100 is configured by stacking the second sheet 20 on the upper surface of the first sheet 10 with a gap.

In this convex input panel 100, the conductive film 22 of the second sheet 20 contacts the conductive film 12 of the first sheet 10 at the pressed input point, and the position on the display panel corresponding to the input point To move the cursor to.

Another concave insulating film 21 whose center is the lowest point P-2 21
-1, the conductive film 22 is formed on the lower surface of the insulating film 21-1
A second sheet 20-1 having a pair of power supply electrodes 23, 24 facing the left and right side edges of the first sheet 10-1 and a second sheet 20-1 is provided on the upper surface of the first sheet 10-1. It is assumed that the concave input panel 100-1 is configured by stacking the two via the above.

In this concave input panel 100-1, the conductive film 22 of the second sheet 20-1 is the first sheet at the pressed input point.
It contacts the conductive film 12 of 10-1 and moves the cursor to a position on the display panel corresponding to the input point.

The center of the input panel of the coordinate input device, that is, the origin of coordinates, corresponds to the center of the display panel of the information processing device. According to the present invention, the surface of the input panel is a convex surface whose center is the apex or a concave surface whose center is the lowest point.

Thus, the center of the input panel can be confirmed by touching it with a finger without looking at the input panel, and the cursor can be moved to a desired position while looking at the display panel. Therefore, a so-called blind operation can be performed and the operability of the coordinate input device is improved.

On the other hand, in the convex input panel or the concave input panel of the present invention, since the surface of the input panel is convex or concave, the surface area of the input panel is larger than that of the flat input panel having the same outer dimensions in plan view.

Therefore, the coordinate input device of the present invention is further miniaturized. In addition, a protrusion or a wrinkle is provided at the apex portion of the second sheet of the convex input panel or at the lowest point of the second sheet of the concave input panel.

By providing a touching portion such as a protrusion or a wrinkle, it becomes easier to confirm the center position of the input panel.
As illustrated in FIG. 4, the vertex P-1 of the convex input panel 100
In the portion, the conductive film 12 of the first sheet 10 and the conductive film 22 of the second sheet 20 are constantly in contact with each other, and when the surface other than the apex of the convex input panel 100 is pressed, the pressed input point causes the second The conductive film 22 of the sheet 20 is in contact with the conductive film 12 of the first sheet 10, and the contact at the apex is disconnected.

Alternatively, at the bottom point of the concave input panel,
When the conductive film of the first sheet and the conductive film of the second sheet are constantly in contact with each other and the surface other than the lowest point of the concave input panel is pressed, the conductive film of the second sheet is pressed at the pressed input point. First
The sheet is in contact with the conductive film of the sheet.

In any of the fourth and fifth aspects of the invention, since the conductive film of the first sheet and the conductive film of the second sheet are in contact with each other at the center of the input panel, the cursor is moved when the information processing device is started. It is displayed on the display board, and the cursor indicates the center position of the display board.

Therefore, when the information processing apparatus is started up, it is not necessary to press the input panel to confirm the cursor position, and the operability of the coordinate input apparatus is further improved.
