Abstract

A tape recorder calculator is disclosed. The tape recorder comprises a cassette charging portion thereof on one side surface of a polyhedron of a housing and digit keys on an other side surface. The display for displaying counted values is also used as a counter display of the tape recorder and is rotatably provided on one side surface of the polyhedron so as to automatically switch its display function in accordance with rotation of the display.

Claims

1. A combination tape recorder/calculator in a polyhedron shape having a cassette charging portion of the tape recorder on one side surface of the polyhedron and digit keys for performing standard calculator functions on another side surface of the polyhedron, said combination comprising a rotatable display portion wherein said display portion indicates a count representative of tape movement when said display portion is switched into a first mode by rotating said display portion until it is aligned with said one side surface and said display portion indicates keyboard entries and calculated results when said display portion is switched into a second mode by rotating said display portion until it is aligned with said another side surface.

2. A device as in claim 1, wherein the combination tape recorder/calculator includes a radio having a dial portion on a third surface of the polyhedron, said rotatable display portion indicating the tuning frequency when the display portion is aligned with the third surface.

3. A multi-mode electronic device, comprising a polyhedron shaped body having a plurality of faces, a tape recorder mounted in the body and having a tape charging portion mounted at one face of the polyhedron, a calculator mounted in the body and having a plurality of digital entry keys projecting through a second face of the polyhedron body, a display portion having a display surface and rotatable relative to the body so that the display surface aligns with different ones of the first and second faces in different positions, said display portion having a digital display viewable at the display surface, switch means coupling said display to said tape recorder for indicating tape advance when the surface is aligned with the first face and for coupling the display to said calculator for displaying entry readouts and calculated readouts when the surface is aligned with the second of said faces.

4. A device as in claim 3, wherein a radio is mounted in said body, said radio including at least one control member on a third of said faces, said switch means coupling said radio to said display so that said display exhibits tuning frequencies when the surface is aligned with the third face.
