Claims

[Scope of utility model registration request]

A frame that includes a substrate including a group of light emitting elements and a group of light receiving elements installed around a display screen so that the row of light receiving elements is on the inside, and a light emitting element on the upper side of the frame and a light receiving element on the lower side of the frame. a first X-value holding means for obtaining a first X-coordinate value from the light-emitting element on the lower side of the frame and a second X-coordinate value from the light-receiving element on the upper side of the frame; a first Y value holding means that obtains a first Y coordinate value from a light emitting element on the right side of the frame and a light receiving element on the left side of the frame;
a second Y value holding means for obtaining a coordinate value; and an X coordinate value determination unit that selects an X coordinate value to be output by comparing the first Y coordinate value or the second Y coordinate value with a Y reference value. and Y-coordinate value determining means for selecting a Y-coordinate value to be output by comparing the first X-coordinate value or the second X-coordinate value with an X reference value. Position detection device.
