Abstract

A decoder for use with a record medium having bits of information thereon in which the decoder can be programmed to produce an indication of an acceptable record having the bits of information thereon in a predetermined pattern corresponding to predetermined information.

Claims

1. A decoder comprising:

means for producing a radio frequency signal, sensor platen means for supporting a record of the type having a pattern of spaced electrically unconnected bits of information thereon of a material which can electrically couple the radio frequency signal and in which said bits are covered by an electrically non-conductive material, said sensor platen means including a common first means for receiving the signal from the signal producing means and a plurality of second means adjacent but spaced from the first means in the same plane, each of said second means being located adjacent said first means so that a bit present on the record will bridge the first means and a respective second means to electrically couple the signal from said first means to a second means which is bridged by a bit, and means electrically coupled to said second means for detecting the signal coupled from said first to said second means.

2. A decoder as in claim 1 wherein said plurality of second means are located adjacent to a side of said first means.

3. A decoder as in claim 1 wherein said first and second means of said sensor platen comprises plates of electrically conductive material on a printed circuit board.

4. A decoder as in claim 1 wherein said first means of said sensor platen is an elongated plate of electrically conductive material and each of said second means of said sensor platen comprises a separate plate of electrically conductive material, said plates of said second means arranged alongside of and spaced from said elongated plate of said first means.

5. A decoder as in claim 1 further comprising a housing for holding said sensor platen and means on said housing for holding a said record in position on said sensor platen.

6. A decoder as in claim 5 further comprising cover means adopted for resting on a second record when in place on said sensor platen.

7. A decoder comprising:

means for producing a radio frequency signal, sensor platen means for supporting a record of the type having a plurality of spaced and electrically unconnected bits of information thereon in a predetermined pattern with the bits being of a material which can electrically couple the signal and with the bits covered by an electrically non-conductive material, said sensor platen means including a common first means for receiving the signal from the signal producing means and a plurality of second means adjacent the first means and arranged in a pattern to accommodate all possible patterns of the bits on the record so that the signal on said first means will be electrically coupled by a bit on said record in the corresponding pattern position to the respective second means, and means electrically coupled to said plurality of second means for detecting the signals coupled by a bit from said first means to a respective one of said second means.

8. A decoder as in claim 7 wherein said first means of said sensor platen is an elongated plate of electrically conductive material and each of said second means of said sensor platen comprises a separate plate of electrically conductive material, said plates of said second means arranged alongside of and spaced from said elongated plate of said first means.

9. A decoder as in claim 7 wherein said detecting means further comprises means responsive only to a predetermined pattern of bits on the record for producing a first output signal.

10. A decoder as in claim 9 wherein said detecting means further comprises means for selectively establishing the predetermined pattern of bits on the record to which the detecting means is to respond to produce the first output signal.

11. A decoder as in claim 9 wherein said detecting means includes means responsive to a pattern of bits on the record of other than said predetermined pattern for providing a seconD signal.

12. A decoder as in claim 10 wherein said detecting means includes means responsive to a pattern of bits on the record of other than said predetermined pattern for providing a second signal.

13. A decoder as in claim 10 wherein the predetermined pattern of bits selected corresponds to a binary number.

14. A decoder as in claim 7 further comprising means for holding the record stationary with respect to the sensor platen as the detecting means operates.

15. A decoder as in claim 7 wherein said detecting means comprises a detector circuit means responsive to the radio frequency energy coupled from the first means to a respective second means by a bit.

16. A decoder as in claim 15 wherein there is a separate decoder circuit means coupled to each of said second means.

17. A decoder as in claim 9 wherein said means for producing said first output signal comprises comparator circuit means for comparing the signals coupled to the respective ones of said second means by the bits on the record with a preset group of signals corresponding to a predetermined pattern on the record.
