Abstract

The invention provides a capacitance touch panel equipped with a button switch. The capacitance touch panel is capable of increasing the dielectric constant between a touch thin panel and a detecting electrode and is capable of maintaining the distance between the touch thin panel and the detecting electrode constant. A button switch and a capacitance touch panel of the capacitance touch panel equipped with a button switch are integrated into one body. The capacitance touch panel comprises a multilayer printing substrate (42) equipped with the detecting electrode (44), a hard dielectric board (46), and the touch thin panel (40). The button switch comprises a metallic spring switch (52) formed in an area where the multilayer printing substrate (42) equipped with the detecting electrode (44) is formed, a button which corresponds to the metallic spring switch (52) and which displays on the surface of the touch thin panel (40), and a metallic spring pressing component (74) which is arranged between the touch thin panel (40) and a metallic spring (58) and which presses down the metallic spring (58) when the button is pressed down.

Description

technical field [0001] The present invention relates to an input device constituting an input operation portion of an electronic device, and more particularly to a touch panel with key switches in which a metal dome switch and a capacitive touch panel are integrated. Background technique [0002] Electronic equipment, such as digital TV broadcast receivers in recent years, has become multifunctional. In addition to key switches, a capacitive touch panel is provided on a remote controller as an input device of such digital TV broadcast receivers. [0003] The key switch is used for channel selection, indicator operation, etc., and the capacitive touch panel is used for input such as indicator operation, text input, and page switching. [0004] On the operation surface of the remote controller, the key switches and the capacitive touch panel are not provided in different areas, but the key switches and the capacitive touch panel are integrated, that is, the key switches are pr...
