Abstract

PURPOSE:To simplify the internal structure to reduce the thickness of the case, by making one of a pair of left and right cases into a two-sided keyboard and by constituting this keyboard so that keys can be depressed commonly from both sides and by causing these keys to correspond to keys on the other case. CONSTITUTION:A desk calculator 1 consists of a right case 2 and a left case 3, and cases are supported rotatably by a shaft 4. Keys provided with key indications 5a are arranged on the surface of the case 2, and key indications 5b are provided on the reverse face of these keys. Meanwhile, keys 11 arranged on the case 3 correspond to keys of case 2 one to one. When a key is depressed from the surface under the state where cases 2 and 3 are superposed, the key 11 is depressed while interlocking with this depression, and prescribed information is input. When the case 2 is opened and a key is depressed from the 5b side to the 5a side of the key undication, prescribed input information is input.
