Problems solved by technology

[0004] However, since the diagonal operation force is composed of a vertical component perpendicular to the operation surface of the panel and a horizontal component parallel to the operation surface of the panel, especially when the operation force is applied diagonally to the panel by finger operation on the panel, Patent Document 1 The device in the device is not able to accurately detect the position of the finger operation on the panel
More specifically, the horizontal component of the operating force leads to inaccurate reading / detection of the position of the finger operation on the panel

no. 1 example

[0037] refer to figure 1 The configuration of the operation input device 100 in the first embodiment of the present invention is described through FIG. 6 .

[0038] like figure 1 As shown, the operation input device 100 is a device for performing operation input for operating the car navigation device 10 , for example. The operation input device 100 can also be used for input to various devices other than the navigation device 10 described above (for example, air conditioners and audio devices).

[0039] like figure 2 and Figure 3A / Figure 3B As shown, the operation input device 100 is provided with an operation panel 110 , an operation unit 120 , a connection body 130 , a strain body 140 , a strain gauge 150 , a support 160 , a signal processor 170 and the like. The connection body 130 , the strain body 140 and the strain gauge 150 are disposed inside the operation unit 120 .

[0040] The operation panel 110 is a circular flat-shaped member. The operation panel 110...

no. 2 example

[0111] Figure 10 An operation input device 100A of the second embodiment is shown. In this embodiment, the shape of the connection body 130 is changed from that of the first embodiment described above to have a connection body 130A.

[0112] The connection body 130A is formed with a single flat spring bent two or more times. Flat springs can be formed, for example, by press working. A part of the connection body 130A is formed to have a thin plate. The amount of bending of the body 130A and the x / y-axis dimensions of the flat spring and the z-axis height of the flat spring after bending are respectively predetermined together with other conditions.

[0113] In addition to the holding function of fixedly holding the operation panel 110 , the operation unit 120 and the strain body 140 , the connection body 130A also provides an operation force transmission function of transmitting the operation force applied to the operation unit 120 to the strain body 140 .

Abstract

An operation input device includes a connection body that has two slopes respectively having an angle against an operation panel to form a gable roof shape, and each of the two slopes has a strain body disposed thereon, and an vertex of the roof-shaped slopes is positioned within a preset distance from an outer face of the operation panel, and the strain body, the connection body and a strain gauge are disposed in an inside of a box-shaped operation unit.

Description

technical field [0001] The present invention generally relates to an operation input device for inputting a control operation controlling, for example, a vehicle navigation device, an air conditioning device, or an audiovisual device. Background technique [0002] A conventional operation input device as disclosed in Patent Document 1 has, for example: a panel serving as an operation surface for touch operation; strain gauge type sensors provided at four corners of the panel for respectively detecting vertical a load; and an arithmetic circuit for calculating the position and direction of the load based on the detected load from the strain gauge. Also, the panel of this operation input device has a stick integrally protruding therefrom and operable for applying a load to the panel. [0003] The operation input device of Patent Document 1 (that is, Japanese Patent Laid-Open No. 2010-86076) detects the position of the finger operation on the panel when the finger performs a t...
