Input device and load detection method of multiple points using the input device

Abstract

[Object] To provide an input device and a multiple point load detecting method capable of obtaining loads on multiple pressing points that are simultaneously pressed. [Solution] An input device 1 of the present invention includes a capacitance type touch panel sensor capable of detecting pressing positions of multiple pressing points A and B that are simultaneously pressed on an operation face 4a, load detection sensors capable of detecting a barycentric position of and a barycentric load on the pressing points A and B, and a controller capable of calculating loads (z1, z2) on the pressing points A and B on the basis of the positional coordinates (x1, y1) (x2, y2) of, the barycentric coordinates (X, Y) of, and the barycentric load (Z) on the pressing points.

Description

technical field [0001] The present invention relates to an input device mounted on a portable device or other electronic equipment, and operated by touching an operation panel with a finger or the like. Background technique [0002] Each of the patent documents listed below describes an input device capable of detecting position coordinates and load of a pressed point when an operation is performed on an operation surface with a finger or the like. [0003] In these patent documents, the pressing point capable of detecting both the position coordinates and the load is one point, but there is no description about the detection of the position coordinates and the load at each pressing point when a plurality of positions are simultaneously pressed. [0004] Prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2009-87311 [0007] Patent Document 2: Japanese Patent Laid-Open No. 2010-146206 [0008] Patent Document 3: Japane...
