Abstract
The operating member is constructed by supporting the button members with the thin sheet member without integrally constructing the button members, and therefore, the device can be downsized and slimmed. The key tops of the button members can be individually surface-treated before assembly, and therefore, a user can easily recognize the kinds of buttons at the time of operation, and an operation mistake can be prevented.
