Abstract
Abstract The invention provides a magnetic reading and/or writing device comprising a guide for a magnetic data carrier and a magnetic head support. The magnetic head support has a stirrup piece movable in translation with respect to a fixed piece and a magnetic head rotatably mounted on the mobile stirrup piece. The mobile stirrup piece is urged resiliently to press the magnetic head against the magnetic carrier.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
In a magnetic reading and/or writing device having a guide for guiding a magnetic data carrier in a first direction, and a magnetic head for reading and/or writing data on said carrier, a magnetic head support comprising: a mobile stirrup piece positioned adjacent said guide with said data carrier positionable therebetween; pivot means fixed to said stirrup piece and pivotally supporting said head for rotation only about an axis parallel to said first direction; a fixed piece fixed adjacent said guide; means associated with said fixed piece for supporting and guiding said stirrup piece only for movement in a linear second direction transverse to said first direction, wherein said fixed piece has two grooves extending in said second direction and in which said pivot means are engaged, said grooves forming a portion of said supporting and guiding means for said mobile stirrup piece; and means for biasing said stirrup piece towards said guide, whereby said carrier is pressed against said head and said guide.
Claim 2
Dependent Claim
164 words
In a magnetic reading and/or writing device having a guide for guiding a magnetic data carrier in a first direction, and a magnetic head for reading and/or writing data on said carrier, a magnetic head support comprising: a mobile stirrup piece positioned adjacent said guide with said data carrier positionable therebetween; pivot means fixed to said stirrup piece and pivotally supporting said head for rotation only about an axis parallel to said first direction; a fixed piece fixed adjacent said guide; means associated with said fixed piece for supporting and guiding said stirrup piece only for movement in a linear second direction transverse to said first direction, wherein said fixed piece has two grooves extending in said second direction and in which said pivot means are engaged, said grooves forming a portion of said supporting and guiding means for said mobile stirrup piece; and means for biasing said stirrup piece towards said guide, whereby said carrier is pressed against said head and said guide.
Claim 3
Dependent Claim
53 words
The device as claimed in claim 1, wherein said two grooves are formed each in a lateral face of said fixed piece and said fixed piece includes a part forming a stop for said mobile stirrup piece in said second direction in which said stirrup piece presses said magnetic carrier against said guide.
Claim 4
Dependent Claim
66 words
The device as claimed in claim 2, wherein said mobile stirrup piece has a central part including a spring guide about which is disposed a spring, said spring comprising said biasing means, said spring guide being fixed to said central part and being slidable in a bore provided in a rear face of said fixed piece to form another portion of said supporting and guiding means.
Claim 5
Dependent Claim
27 words
The device as claimed in claim 3, wherein said fixed piece is mounted on a plate by means of screws engaging in grooves in said fixed piece.
Claim 6
Dependent Claim
40 words
The device as claimed in claim 4, including a thin non-magnetic foil resistant to abrasion fixed on said guide and adjacent the magnetic head so that said foil protects the magnetic head against wear during passage of the magnetic carrier.
