Abstract

An educational and entertainment device wherein a microcomputer is mounted in a housing to receive user generated data presented by moving a conducting stylus across perpendicular arrays of conductors on a work surface formed on the housing and presents information to the user via audio and visual devices. The conductors of each array are organized into first write groups formed of a plurality of interconnected conductors which can be placed in a selected electrical state by words written to the write groups and into read groups, read by the microcomputer, formed of a plurality of interconnected conductors interspersed with the conductors of the write groups. Additional, second write groups are interspersed with the first write groups and read groups. The arrays are alternatively mounted on the work surface or on a support member which can be detachably mounted on the work surface and connectors are provided for connecting the arrays on the support member to the microcomputer. The arrays are formed into a lamina by deforming arrays of wires with a die, injecting an insulating material in the interstices between the wires to form a lamina, and subsequently removing portions of the lamina adjacent the surface thereof.

Dependent claims

In an automated educational and entertainment device of the type including a housing having a work surface formed thereon, computer means within the housing for processing data inputted to the computer means and generating information for the user of the device, output means mounted on the housing and electrically communicating with the computer means for providing information from the computer means to the user of the device, and input means supported by said work surface and electrically communicating with the computer means for providing user generated data to the computer means, the improvement wherein the input means is formed on a support member separate from the housing and wherein the device further comprises communication means formed partially on the housing and partially on the support member for providing electrical communication between the input means and the computer means;

the input means further comprising a first array of substantially parallel conductors extending along the surface of the support member;
a second array of substantially parallel conductors extending along the surface of the support member substantially perpendicularly to the first array, wherein each array is comprised of:
a plurality of write groups each comprising a plurality of interconnected, spaced conductors extending across the support member;
and a plurality of read groups each comprised of a plurality of interconnected, spaced conductors extending across the support member and interspersed with conductors of the write groups such that one conductor of each read group is disposed between a selected pair of conductors of each write group;
and means for connecting the write groups and the read groups to the I/O ports of a computer.
