Embodiment Construction

[0043] Hereinafter, an input device according to an embodiment of the present invention will be described with reference to the drawings.

[0044] figure 1 It is a figure which shows an example of the structure of the input device of this embodiment. figure 1 The shown input device has a substrate 10 for receiving input operations and four support portions 20 elastically supporting the substrate 10 , and inputs information corresponding to various input operations performed by touching the substrate 10 with a finger, a pen, or the like. This input device has a function of detecting a force applied to the substrate 10 and a function of detecting the position of an object approaching the substrate 10 as a detection function for inputting information corresponding to an input operation.

[0045] Substrate 10 in figure 1 In the example shown in FIG. The substrate 10 accepts input operations on the first surface 101 . In addition, in figure 1 In the example shown above, the pl...

Abstract

To provide an input device that detects force applied to a substrate as input operation is performed with simple constitution and decreases the number of components. When force is applied to a substrate (10) as input operation is performed, a housing space (25) varies elastically in capacity and a conductive member (41) as an elastic member housed in the housing space (25) is caused to elasticallydeform. According to the elastic deformation of the conductive member (41), a variable resistance part (43) varies in resistance value and a signal generated by a signal generation part changes. Theneed for a mechanism component such as a spacer etc., for forming a gap between electrodes is eliminated, and a mechanism component which causes displacement and elastic deformation for detecting force need not be provided separately from a support part (20).

Description

[0001] This application is a divisional application of the Chinese patent application No. 201610885553.9 and the invention name "input device" submitted by the applicant on October 11, 2016. technical field [0002] The present invention relates to an input device for detecting an input operation such as pressing a substrate, and a force sensor used in the input device. Background technique [0003] Patent Document 1 describes an input device including a proximity sensor that detects the approach of an object and a force sensor (load cell) that detects a force applied from the outside. In this conventional input device, both the proximity sensor and the force sensor perform sensing and detection based on changes in electrostatic capacitance. A conventional input device has a first substrate and a second substrate. Electrodes for the proximity sensor are arranged on the front surface of the first substrate, and electrodes for the force sensor are arranged on the back surface...
