Abstract
A keyboard device and a personal computer including a housing member made slidable, so that a membrane switch is not slid. Such a structure, designed to make the keyboard device and the personal computer thinner, makes it possible to provide very reliable, cheap, thin keyboard devices and personal computers which allow an electrical circuit in the personal computer and the membrane switch to be easily connected. Accordingly, the keyboard device and the personal computer having the above-described structure overcome the problems produced in conventional keyboard devices and personal computers using conventional keyboard devices. These were made thinner by making the membrane switch slide, which has resulted in a complicated electrical connection between an electrical circuit in the personal computer and the membrane switch, increased costs, and lack of electrical reliability.
