Embodiment approach 1

[0028] Hereinafter, in order to explain this invention in detail, the form for implementing this invention is demonstrated based on drawing.

[0029] figure 1 It is an external perspective view of the electronic device 100 to which the touch panel button structure of Embodiment 1 is applied.

[0030] Electronic device 100 includes touch panel buttons 1 , touch panel 50 , a liquid crystal display (not shown), and the like. The touch panel 50 is a capacitive touch panel.

[0031] figure 2 It is an exploded perspective view of electronic device 100 to which the button structure for a touch panel of Embodiment 1 is applied.

[0032] The button 1 for a touch panel to which the button structure for touch panels of Embodiment 1 is applied is set as the button 1 for touch panels. The button 1 for a touch panel includes a first operation portion 2 , a second operation portion 3 , a holder 4 , an elastic member 5 , and a support portion 6 .

Embodiment approach 2

[0064] Figure 8 It is a cross-sectional view of an electronic device to which the button structure for a touch panel according to Embodiment 2 is applied.

[0065] Hereinafter, structures having the same or equivalent functions as those described in the first embodiment are denoted by the same symbols, and descriptions thereof are omitted or simplified.

[0066] A button for a touch panel to which the button structure for a touch panel of Embodiment 2 is applied is referred to as a button 1A for a touch panel.

[0067] In Embodiment 1, the case where the rubber switch 5A was made conductive was demonstrated. If the rubber switch has conductivity, there is a problem that the key durability is reduced, and the rubber is cured, thereby deteriorating the operational feeling. The key structure for a touch panel of the second embodiment is formed to solve the above problems. In Embodiment 2, a non-conductive rubber switch 5A- 1 is used as the elastic member 5 .

[0068] The rub...

Embodiment approach 3

[0078] Figure 10 It is a cross-sectional view of an electronic device to which the button structure for a touch panel according to Embodiment 3 is applied.

[0079] Hereinafter, structures having the same or equivalent functions as those described in Embodiment 1 and Embodiment 2 are denoted by the same symbols, and descriptions thereof are omitted or simplified.

[0080] A touch panel button to which the touch panel button structure of the third embodiment is applied is referred to as a touch panel button 1B.

[0081] In Embodiment 2, the case where the non-conductive rubber switch 5A- 1 is used as the elastic member 5 and the conductive member 7 is used has been described. In Embodiment 3, the case where the electroconductive member 7 is not used is demonstrated.

[0082] In the third embodiment, a non-conductive rubber switch 5A- 2 is used as the elastic member 5 . The rubber switch 5A-2 has a protrusion 5a1, a base 5a2, and a skirt 5a4.

[0083] The protrusion 5 a 1 i...

Abstract

It includes: a first operation part (2), which is made of a conductor and is pressed down; a support part (6), which is made of an insulator and fixed to the capacitive touch panel (50) Supporting the first operating part (2) from above; the elastic member (5), the elastic member is configured to have a non-conductive fixed surface fixed toward the touch panel (50), and the elastic member is accommodated in the support portion (6) Inside, when the first operation part (2) is depressed, the elastic member (5) is elastically deformed, and the depression operation of the first operation part (2) is detected through the touch panel (50).

Description

technical field [0001] The present invention relates to a button structure for a touch panel, a button for a touch panel and electronic equipment. Background technique [0002] Electronic devices such as navigation devices include a display with a capacitive touch panel and a mechanical switch mechanism. [0003] Patent Document 1 discloses a car navigation device, which includes an LCD display device, a touch panel, a switch knob, a switch knob push rod, a tact switch, a tact switch substrate, and the like. [0004] Since there is no unevenness on the surface of the touch panel, the user has to look at the touch panel when operating the touch panel. On the other hand, the switch knob protrudes relative to the surface of the touch panel. Therefore, the user can perform an intuitive operation without looking at the switch knob. In addition, the switch mechanism has a tact switch. Therefore, the user can obtain an operational feeling at the time of operation. [0005] pri...
