Foldable data collecting and processing device

摘要

A foldable data collecting device includes a first case and a second case mutually connected in a foldable manner, and a plate hinged between the first case and the second case by an opening/closing support. A sheet- like keyboard is disposed on the surfaces of the plate and one face of each of the first case and the second case. In case a key on the plate is to be depressed, the plate is folded down toward either the first case or the second case so that the side having the key to be depressed is directed upwardly.
