Abstract
A latch mechanism which engages with a main body is provided at pivoting edges of a keyboard and a cover which are provided at the main body so as to be openable and closable. The latch mechanism includes a latch member which is movable from a first position, at which the cover and the keyboard are engaged with the main body, to a second position, at which the engaged state of the cover and the keyboard with the main body is released. The latch member releases only the engaged state of the main body and the cover at a third position which is between the first position and the second position. Further, the latch member is usually urged to the first position by a compression coil spring which deforms upwardly in a convex shape at the second position of the latch member.
