Abstract
A keyboard section 9, whose operation keys are allocated linearly in a longitudinal direction on the cylinder chassis 1, is established except for at the location of the grip section 1a, which is held by the user when the cylinder chassis 1 is used as a writing tool. Due to this, the area of the operation keys of the keyboard section 9 can be large. And for the operation keys to be allocated linearly can preserve a great deal of space for the display section 3.
