  • Publication number: 20150193017
    Abstract: An operating device includes: right and left hold sections to be held by a user, the right and left hold sections provided with first operating members; and a central section interconnecting the right and left hold sections. The operating device has a second operating member forming an upper surface of the central section. The second operating member includes a touch sensor located between the first operating members of the right and left hold sections, and is so supported as to be capable of vertical movement in response to a user s pressing-down operation. The second operating member is plate-like in shape, so that user s fingers can easily reach the second operating member in a condition where the user is holding the hold sections. As a result, operability of the operating device can be enhanced.
