Abstract
A magnetic head suspension apparatus for reading and/or recording information during photofinishing of photographic filmstrips comprises an elongated pivotally mounted follower bar having a pair of magnetic heads attached thereto in a predetermined orientation with the information tracks on the filmstrip. A pair of film edge followers are pivotally attached to the ends of the bar respectively. A spring is connected between the bar and a fixed support to bias the bar to urge the edge followers into engagement with the film edges of the filmstrip.
Claims17
Apparatus for supporting at least one magnetic head in a predetermined orientation with at least one information track on a photographic filmstrip, the track having a predetermined orientation with respect to one edge of the filmstrip, said apparatus comprising:
- a support structure;
- means for pivoting in close proximity to the filmstrip, said pivoting in close proximity to the structure;
- at least one magnetic head attached to said pivoting means in a predetermined orientation with respect to the filmstrip track;
- a pair of spaced film edge follower means mounted on said pivoting means for engagement with opposite longitudinal edges of the filmstrip respectively;
- and
- means for biasing said pivoting means to urge said pair of spaced follower means into engagement with the edges of the filmstrip to maintain the location of said magnetic head with respect to one of the edges of the filmstrip and to assist in centering the filmstrip in its desired path.
Apparatus for supporting at least one magnetic head in a predetermined orientation with at least one edge of a photographic filmstrip, said apparatus comprising:
- at least one elongated follower bar extending across the filmstrip;
- means for supporting said bar for pivotal movement;
- a pair of edge followers pivotally supported on the ends of said bar respectively for engagement with opposite longitudinal edges of the filmstrip respectively;
- at least one magnetic head supported on said bar in predetermined relationship with one edge of the filmstrip;
- and
- means for biasing said bar to urge said pair of edge followers into engagement with said edges respectively, whereby during transport of the filmstrip said head will have a substantially consistent orientation with respect to one of the edges of the filmstrip and said means for biasing said bar assists in centering the filmstrip in its desired path.
Apparatus for supporting at least one magnetic head in a predetermined orientation with at least one edge of a photographic filmstrip, said apparatus comprising:
- a first elongated follower bar extending across the filmstrip;
- a second elongated follower bar parallel to said first bar, said second bar extending across the filmstrip;
- means for supporting said first and second bars for pivotal movement;
- a pair of edge followers pivotally supported on the ends of said first and second bars respectively for engagement with opposite longitudinal edges of the filmstrip respectively;
- at least one magnetic head supported on said first and second bars in predetermined relationship with one edge of the filmstrip;
- and
- means for biasing said first and second bars to urge said followers into engagement with said edges respectively, whereby during transport of the filmstrip said head will have a substantially consistent orientation with respect to one of the edges of the filmstrip and said means for biasing said first and second bars assists in centering the filmstrip in its desired path.
