  • Input devices and electronic device using said input devices
    Patent number: 9524835
    Abstract: Input device in which a defect of a control disk is eliminated while making use of an advantage of the control disk and an electronic device using the input device. The input device may include: an operation panel, which may be operated by a user; a board, which may be arranged to be opposed to a surface opposite to an operation surface of the operation panel operated by the user; a conductive elastic body and a pusher, which may be fixed on the operation panel; and a sensor portion and a member to be pressed, which may be placed on the board to be opposed to the conductive elastic body and the pusher, respectively.
    Type: Grant

  • Internally-illuminable push-button switch unit
    Patent number: 5573107
    Abstract: An improved internally-illuminable push-button switch unit is proposed, which is an assembly comprising:(a) an upper sheet member integrally consisting of a first elastic sheet having such a light-transmissivity as to ensure image-visibility therethrough and a key-top part made from a light-transmitting synthetic resin having a Shore D hardness of at least 40 and protruded on the upper surface of the first elastic sheet;(b) a lower sheet member integrally consisting of a second light-transmitting elastic sheet and a click-plate presser made from a light-transmitting material and protruded on the lower surface of the second elastic sheet, the lower sheet member being positioned below the upper sheet member;(c) a light-conducting plate positioned below the lower sheet member;(d) a click plate positioned below the lower sheet member;(e) a circuit board positioned below the lower sheet member; and(f) a light source positioned below the lower sheet member and above the circuit board,at least either one of the firs
