Embodiment Construction

[0060] One mode for implementing the present invention will be described using the following drawings.

[0061] figure 1is a schematic diagram showing the longitudinal cross-sectional structure of the main part of the electrostatic capacitive input device 11 (hereinafter referred to as "input device"), figure 2 is a perspective view showing the appearance of the input device 11 viewed from the upper side, image 3 It is a perspective view showing the appearance of the input device 11 viewed from the lower surface side. Such an input device 11 serves as, for example, Figure 4 The input device 11 of the portable information terminal 21 shown is used.

[0062] First, the portable information terminal 21 will be briefly described.

[0063] Figure 4 The illustrated portable information terminal 21 is formed in a thin rectangular parallelepiped shape, and is provided with a rectangular display 22 on most of it except a part of the front. The input device 11 and other opera...

Abstract

The present invention provides an electrostatic capacitive input device for input devices used in portable information terminals and the like, which can reliably perform various input operations with fingertips and contributes to thinning the device. The capacitive input device of the present invention includes a touch substrate part (32) having a touch electrode (32a) on the upper surface for detecting a position on a plane according to a change in capacitance, and having a touch electrode (32a) on the lower surface for the touch electrode The ground electrode (32b) of (32a). Further, a displacement electrode (33a) facing the ground electrode (32b) is provided below the touch substrate part (32) with a gap (51) therebetween. The displacement electrode (33a) detects a pressing force based on a change in capacitance caused by a reduction in the distance between the displacement electrode (33a) and the ground electrode (32b). In the thickness direction, various input operations can be performed by having the direction detection part (I) and the pressure detection part (II) partially shared and overlapped.

Description

technical field [0001] The present invention relates to a kind of electrostatic capacitive input device that is used for such as electronic equipments such as mobile phone and PC (Personal Computer), PDA (Personal Digital Assistants), television set, video recorder, more specifically, relates to feel with finger or Capacitive input device that performs various input operations intuitively. Background technique [0002] As an input device for performing various input operations, there is an input device disclosed in Patent Document 1 below. It is an input device having a structure including position coordinate detection means for detecting coordinates of an indicated position of a position indicator on an input detection surface, and a pressing force detection means for detecting a pressing force of the position indicator on the input detection surface . [0003] Furthermore, the position coordinate detection device is composed of an optical sensor, and the pressing force d...
