Touch panel coordinate rotation device
First Claim
1. A touch panel coordinate rotation device, which is provided in a touch panel device comprising a touch panel provided on the image plane of a display device and a coordinate detecting device for detecting the touched position on the touch panel and outputting the coordinates of the touched position, comprising:
- a memory device for storing a rotation angle of an image on the display device based on the standard angle; and
a coordinate calculating device for calculating the new coordinates by rotating the coordinate output from the coordinate detecting device at the rotation angle stored in the memory device, when the rotation angle stored in the memory device is not 0, wherein said coordinate calculating device calculates the new coordinates using the following formulas;

Abstract
A touch panel coordinate rotation device is provided in a touch panel device that includes a touch panel provided on the image plane of a display device and a coordinate detecting device for detecting the touched position on the touch panel and outputting the coordinates of the touched position. The touch panel coordinate rotation device can rotate the coordinates of a touch panel at a desired angle. The touch panel coordination rotation device includes a memory device for storing a rotation angle of an image on the display device based on the standard angle, and a coordinate calculating device for calculating the new coordinates by rotating the coordinate output from the coordinate detecting device at the rotation angle stored in the memory device, when the rotation angle stored in the memory device is not 0.
