ABSTRACT:
An information processing device suitable for portable use. The information processing device includes a first member (e.g., a cover having a display unit), a second member (e.g., a body having a keyboard unit), a connecting member for connecting the first and second members so that these members can be relatively displaced, and a switch mechanism provided in the second member. The second member has an engaging portion (e.g., a hole), and the first member includes a hook member to be engaged with the engaging portion. The switch mechanism functions to switch on and off a signal in synchronism with movement of the hook member. According to the structure having such switch mechanism, it can be possible to provide a device which can prevent an improper switching operation.
