Position coordinate input device |
摘要 |
A position coordinate input device including an input plate subjected, at a point, to an external force with a finger, etc. so as to input data of coordinates of the point into a computer and the like. The device further includes four elastic support members for supporting the input plate, a pair of two first detectors yielding outputs of temperature characteristics of a first sign and a pair of two second detectors yielding outputs of temperature characteristics of a second sign opposite to the first sign so as to enable accurate detection of the coordinates of the point of application of the external force in a simplified construction.
