ABSTRACT:
The present invention relates to an improved calculator housing which includes a number-entry key housing having two lugs extending longitudinally from its upper ends, each with a first annular boss projecting inwardly from the lugs; a display housing having a hollow cylindrical extension portion with a circular protrusion at one of its end and a second boss at the other end, which extends between the lugs of the number-entry key housing; both the circular protrusion and the second annular boss being movably inserted into the first annular bosses, and means for interengaging the first and second annular bosses to limit the movement of the second annular boss relative to the second annular boss so that the display housing can be folded relative to the number-entry key housing adjusted and fixed in a suitable position according to the user's need, for seeing the display clearly and comfortably in practical use.
