Abstract
A magnetic card handling apparatus has a rotatable capstan and a magnetic head spaced apart a distance exceeding the thickness of a magnetic card on appropriate sides of a card running groove until the presence of a magnetic card therebetween is detected. The distance between the capstan and the magnetic head is thereupon decreased whereby the magnetic card is pinched between the magnetic head and the capstan and is driven past the magnetic head for recording/or reproduction of signals. Separate card running grooves with associated reproduce and record heads and separate card detecting apparatus may be provided for reproduction and recording to permit dubbing signals reproduced from one magnetic card onto another magnetic card.
Claims26
A magnetic card handling apparatus for handling a magnetic card having at least an end, an edge and a thickness;
- comprising:
- at least one card running groove for receiving said edge of said magnetic card;
- a magnetic head adjacent one side of said groove;
- a rotatable capstan adjacent the other side of said card running groove opposed to said magnetic head;
- means for spacing said magnetic head and said rotatable capstan apart a first distance exceeding said thickness of said magnetic card;
- detecting means for detecting the presence of said magnetic card between said magnetic head and said rotatable capstan;
- and
- means responsive to said detecting means for decreasing the distance between said magnetic head and said rotatable capstan to a second distance smaller than said first distance whereby said magnetic card is pinched between said magnetic head and said rotatable capstan so as to be driven by the latter.
A magnetic card handling apparatus for handling a magnetic card having at least an end, an edge and a thickness;
- comprising:
- at least one card running groove for receiving said edge of said magnetic card;
- a reproduce magnetic head adjacent one side of said groove;
- a rotatable capstan adjacent the other side of said card running groove opposed to said magnetic head;
- means for spacing said magnetic head and said rotatable capstan apart a first distance exceeding said thickness of said magnetic card;
- detecting means for detecting the presence of said magnetic card between said magnetic head and said rotatable capstan;
- means responsive to said detecting means for decreasing the distance between said magnetic head and said rotatable capstan to a second distance smaller than said first distance whereby said magnetic card is pinched between said magnetic head and said rotatable capstan so as to be driven by the latter;
- a second card running groove;
- a record head adjacent one side of said second card running groove;
- a second rotatable capstan adjacent the other side of said second card running groove opposed to said record head;
- second means for spacing said record head and said second rotatable capstan apart a third distance exceeding said thickness of said magnetic card;
- second detecting means for detecting the presence of said magnetic card between said record head and second rotatable capstan;
- and
- second means responsive to said second detecting means for decreasing the distance between said record head and said second rotatable capstan to a fourth distance smaller than said third distance whereby said magnetic card is pinched between said record head and said second rotatable capstan.

- a second card running groove;
- a record head adjacent said second card running groove;
- and
- a second rotatable capstan adjacent the side of said second card running groove opposite to said record head.
