Sanyo produced a number of distinctive early calculators. The styling of this model is very similar to a portable transistor radio of the period, even down to the cooling louvres which resemble the speaker grille of a radio. The carrying handle can be pushed flushed with the casing or can be folded under the back to tilt the calculator forward at a more ergonomic angle.
See also the Sanyo ICC-809 for a similar, hand-held model.
