    • 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.
    • 有效地访问存储的编码数据的紧凑型便携式卡形数据存储装置具有由多个水平布置的太阳能电池组成的供电装置,该多个水平布置的太阳能电池装配在印刷电路板的一侧,印刷电路板的两侧印有印刷电路。 印刷电路板的另一侧装配有分别构成半导体存储器的半导体芯片和用于将从所述半导体存储器读出的数据转换为串行编码数据的微计算机,以及根据所述编码的光学控制的光发射元件 数据。 半导体芯片和用于发光元件的驱动系统被供给从电源装置传送的电能。 包括印刷电路板的电路元件部分被密封在合成树脂壳体中,从而完全以平板形式构建数据存储装置。
