Abstract

The device reads card 10 which has embossed bumps 12. Card 10 also has an opening 14 near its leading edge. Bumps 12 are formed on only one-half of card 10. Printing appears on the other half. Indentation 16 in slot 18 assures that only a properly oriented badge is inserted in the reader. If card 10 is inserted in the reader with bumps 12 adjacent to any portion of slot 18 except indented portion 16, bumps 12 interact with the edge of slot 18 to prevent card 10 from being inserted. In drawing A, the front of the reader has badge release button 20. A bank of pressure-sensitive switches 22 is contained in the upper portion of the reader. Coded electrical signals representing the information content of card 10 are applied to external control circuitry, not shown, through cable 24.

Card Reader

The device reads card 10 which has embossed bumps 12. Card 10 also has an opening 14 near its leading edge. Bumps 12 are formed on only one-half of card 10. Printing appears on the other half. Indentation 16 in slot 18 assures that only a properly oriented badge is inserted in the reader. If card 10 is inserted in the reader with bumps 12 adjacent to any portion of slot 18 except indented portion 16, bumps 12 interact with the edge of slot 18 to prevent card 10 from being inserted. In drawing A, the front of the reader has badge release button 20. A bank of pressure-sensitive switches 22 is contained in the upper portion of the reader. Coded electrical signals representing the information content of card 10 are applied to external control circuitry, not shown, through cable 24.

In drawings B and D, cam bar 26 is connected to button 20. When there is no card 10 in the reader, hooked end 28 of bar 26 is hooked over projection 30 of latch 32, maintaining bar 26 and affixed button 20 in a depressed position. Under these conditions, pressure pad 34 is held in a lowered position by the fact that bars 36 projecting from pad 34 are resting on high portions 38 of bar 26.

When card 10 is inserted in the reader, its leading edge rides up inclined stud 40 forcing spring arm 42 down. The leading edge then contacts release spring 43, forcing the spring back and causing it to exert a forward force on card 10. The leading edge also contacts latch 32 causing it to rotate in a clockwise direction about pin 44. This permits hook 28 to rise above projection 30 to release bar 26. Compressio...
