BUTTON INPUT DEVICE WITH E-PAPER

摘要

A button input device using an E-paper is provided to improve durability of the button input device by supplying an operational sense to a user without applying physical pressure to the E-paper during the operation of the button. A button input device(101) using an E-paper(21) includes a button(10), an elastic member(40), and a switch substrate(50). The button has a transparent window(11) and a base unit(12) protruded to a rear side from an external region of the transparent window. A display region is arranged below the window and a pair of holes(25,35) are prepared at the external region of the display region(27) to insert the base unit of the button. The elastic member is elastically deformed by the base unit of the button when the button is pressed. The switch substrate is arranged below the elastic member. A switch(51) is prepared at the switch substrate to generate a signal by a push at a position corresponding to a bottom of the base unit of the button.
