Abstract

Abstract A card handler for reading information from, and writing information onto, a card or credential. The handler includes a housing assembly in which magnetic read/write heads are rotatably mounted; a card holder assembly; pressure pads carried by the housing assembly so as to encompass the path of rotary motion of the magnetic heads; and means for moving the housing assembly and the pressure pads so as to clamp the card between the pads and the card holder assembly, with the heads in operative proximity to the card.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 134 words
In a system for reading or writing information on a magnetic card: card-holding means for receiving said card, a clamping mechanism, means for moving said clamping mechanism into engagement with said card, a magnetic head, means for moving said magnetic head across tHe surface of said card, a housing assembly, and a magnetic head assembly, and wherein said card-holding means includes a card holder assembly, said magnetic head is mounted on the magnetic head assembly which is rotatably mounted within said housing assembly, said clamping mechanism includes pressure pads carried by said housing assembly, and said means for moving said clamping mechanism comprises means for moving said housing assembly and said pressure pads to clamp the card between said pads and said card holder assembly with said head in operative proximity with the card.
Claim 2
Dependent Claim 134 words
In a system for reading or writing information on a magnetic card: card-holding means for receiving said card, a clamping mechanism, means for moving said clamping mechanism into engagement with said card, a magnetic head, means for moving said magnetic head across tHe surface of said card, a housing assembly, and a magnetic head assembly, and wherein said card-holding means includes a card holder assembly, said magnetic head is mounted on the magnetic head assembly which is rotatably mounted within said housing assembly, said clamping mechanism includes pressure pads carried by said housing assembly, and said means for moving said clamping mechanism comprises means for moving said housing assembly and said pressure pads to clamp the card between said pads and said card holder assembly with said head in operative proximity with the card.
Claim 3
Dependent Claim 28 words
The device of claim 1 wherein said pressure pads are mounted to said housing assembly so as to enclose the path of rotary motion of said magnetic head.
Claim 4
Dependent Claim 23 words
The device of claim 1 wherein said card holder assembly includes an erase coil disposed therein in alignment with said magnetic head assembly.
Claim 5
Dependent Claim 35 words
The device of claim 1 wherein said means for moving said housing assembly comprises a spring device connected between said card holder assembly and said housing assembly, and a solenoid coupled to said housing assembly.
Claim 6
Dependent Claim 48 words
The device of claim 1 further comprising a shaft journaled in said housing assembly, means for securing said magnetic head assembly for rotation with said shaft while permitting relative axial movement thereof, and a tension device disposed along said shaft and acting between said head and said shaft.
Claim 7
Dependent Claim 36 words
The device of claim 5 wherein one of said pressure pads is rotatably mounted on said shaft; and further comprising a spring device mounted on said shaft and acting between said pressure pad and said shaft.
Claim 8
Dependent Claim 20 words
The device of claim 6 wherein another of said pressure pads is mounted on the casing of said housing assembly.
Claim 9
Dependent Claim 33 words
The device of claim 1 further comprising means for sensing the approach of a person; and power means for rotating said magnetic head assembly; said power means being activated by said sensing means.
Claim 10
Dependent Claim 35 words
The device of claim 8 wherein said means for moving said housing assembly responds to said sensing means to move the housing assembly away from said card holder assembly and permit insertion of a card.
Claim 11
Dependent Claim 60 words
The device of claim 9 wherein said card holder assembly includes a card-sensing device; and said means for moving said housing assembly into engagement with said card, responds to said card-sensing device for positioning said pressure pads to clamp the card between said pads and said card holder assembly and for positioning said head in operative proximity with the card.
Claim 12
Dependent Claim 18 words
The device of claim 10 further comprising means for applying read/write electrical signals to said magnetic head assembly.
Claim 13
Dependent Claim 65 words
The device of claim 11 further comprising means for sensing the end of an acceptable read/write cycle; and means for deactivating said power means; wherein said means for moving said housing assembly responds to said read/write-cycle-sensing means to move said housing assembly out of engagement with said card to permit removal of said card, and said power deactivation means is controlled by said read/write-cycle-sensing means.
