  • Patent number: 7405373
    Abstract: The switch structure according to the present invention is obtained by interposing an elastic connection member between the circuit board provided with electrodes and a push switch fixed to a case of an electronic device. The elastic connection member has a structure in which conductive layers and insulation layers are alternately laminated. The conductive layers of a first lamination layer surface on which the conductive layers and the insulation layers of the elastic connection member are exposed abut against the electrodes so that the electric connections therebetween are established. The push switch is pushed down, and a contact portion thereof abuts against the plurality of conductive layers on a second lamination layer surface, whereby the electrodes are in a conductive state. Even if the push switch is pushed strongly, the elastic connection member deforms to absorb the force. As a result, the switch structure which hardly breaks is obtained.

  • Patent number: 6965067
    Abstract: Provided is a guitar tuner that is capable of tuning each string of a guitar with a capotasto being attached thereto to a specified pitch. The guitar tuner includes attachment position setting means for, when the capotasto is attached to the guitar, setting an attachment position of the capotasto to the tuner, and a pitch of each string can be automatically set to a pitch that is specified in the attachment position of the capo.
