Abstract

The apparatus includes a mechanical-optical translator mechanism based on Boolean logic and incorporating coded shutter plates. The output depends on the plates selected. The output is further dependent on direction of movement, extent of movement by increments, and patterns of opaque and transparent areas.

Boolean Logic Translater

The apparatus includes a mechanical-optical translator mechanism based on Boolean logic and incorporating coded shutter plates. The output depends on the plates selected. The output is further dependent on direction of movement, extent of movement by increments, and patterns of opaque and transparent areas.

Printer 1, in drawing AA, includes print head 2 and document 3 on platen 4. A character is selected by depressing keybutton 5 and keylever 6 to move interposer 7 that is representative of a number of interposers. This trips clutch 9 to rotate filter shaft 10 counterclockwise, thus moving interposer 7 to the left and operating bails 11. The latter rotate and tilt print head 2 through selection block
12. After selection, head 2 is rocked against document 3 to print the character.

Associated with printer 1 is mechanical-optical translator 14. The latter includes shutter plates 16...18 supported for vertical movement by contractable members 19...21 on plate 22 that is arranged for operation by cam 23. As shaft 10 rotates, clutch 9 also drives cam 23 which tends to raise plates 16...18. Positioned adjacent such plates are stop studs 24...26 arranged for operation, as by selector element 27 on keylever 6. Any selected stud 24...26 prevents its associated plate 16...18 from being raised by cam 23. Plates 16...18 have opaque and transparent areas as in drawings BB...GG. Light source 30 is directed through the plates after selection and activat...
