Abstract
A compact portable card-shaped data memory device which effectively accesses stored coded data has a power supply device consisting of a plurality of horizontally arranged solar cells fitted to one side of a printed circuit board, both sides of which are impressed with printed circuit. The other side of the printed circuit board is fitted with semiconductor chips respectively constituting a semiconductor memory and a microcomputer for converting data read out of said semiconductor memory into serial coded data, and a light-emitting element which is optically controlled in conformity with said coded data. The semiconductor chips and a drive system for the light-emitting element are supplied with electric energy delivered from the power supply device. The circuit element section including the printed circuit board is sealed in a synthetic resin case, thereby constructing the data memory device wholly in a flat card form.
