MAGNETIC TAPE TRANSDUCING SYSTEM
First Claim
1. A magnetic transducing apparatus comprising in combination:
- a magazine containing magnetic tape and including supply and take-up means for a length of elongated magnetic tape, said magazine having sidewalls and end walls surrounding said tape, an opening in an end wall of said magazine, means for guiding a portion of said tape in a fixed path past said end wall opening, a first cylindrical member rotatably supported behind said portion of said tape which is guided in said fixed path, a second cylindrical member, a magnetic transducer, a common support for supporting said second cylindrical member and said magnetic transducer, a base having means for removably and predeterminately supporting said magazine at a location on said base whereby said second cylindrical member and said magnetic transducer are in direct alignment with said end wall opening in said magazine, means for guiding said common support in movement towards and away from said magazine along a path wherein said transducer may engage said portion of said tape disposed at said end wall opening and may clear said magazine, power operated means for driving said common support from a first location wherein said second cylindrical member is out of operable contact with said tape and is disposed away from said magazine to a second location wherein said second cylindrical member is engaged against and is pinching said tape against said first cylindrical member and said transducer simultaneously engages said tape, means for causing said transducer to move towards and operatively engage said portion of said tape aligned with said opening in said end wall of said magazine, and means for power rotating one of said first and second cylindrical members when said first and said second cylindrical members are engaging and pinching tape therebetween to drive said tape between saId supply and said take-up means.

Abstract
A magnetic tape transducing system is provided having a simple mechanism for simultaneously magnetically coupling to and driving a magnetic record tape. In one form, a magnetic transducer and drive wheel are simultaneously urged into operative relationship with a magnetic tape by the lineal movement thereof wherein the tape is simultaneously engaged by a transducer and pinched between drive and depressor rolls. In another form, the tape is driven within a housing between a supply reel and a take-up reel and a common mount for a transducer and a tape drive wheel of cylinder is lineally actuated to engage the tape which is driven past an opening in the wall of the housing.

1. A magnetic transducing apparatus comprising in combination:
- a magazine containing magnetic tape and including supply and take-up means for a length of elongated magnetic tape, said magazine having sidewalls and end walls surrounding said tape, an opening in an end wall of said magazine, means for guiding a portion of said tape in a fixed path past said end wall opening, a first cylindrical member rotatably supported behind said portion of said tape which is guided in said fixed path, a second cylindrical member, a magnetic transducer, a common support for supporting said second cylindrical member and said magnetic transducer, a base having means for removably and predeterminately supporting said magazine at a location on said base whereby said second cylindrical member and said magnetic transducer are in direct alignment with said end wall opening in said magazine, means for guiding said common support in movement towards and away from said magazine along a path wherein said transducer may engage said portion of said tape disposed at said end wall opening and may clear said magazine, power operated means for driving said common support from a first location wherein said second cylindrical member is out of operable contact with said tape and is disposed away from said magazine to a second location wherein said second cylindrical member is engaged against and is pinching said tape against said first cylindrical member and said transducer simultaneously engages said tape, means for causing said transducer to move towards and operatively engage said portion of said tape aligned with said opening in said end wall of said magazine, and means for power rotating one of said first and second cylindrical members when said first and said second cylindrical members are engaging and pinching tape therebetween to drive said tape between saId supply and said take-up means.
-
2. A magnetic tape transducing apparatus in accordance with claim 1 wherein said power operated means comprises a bistable lineal actuator operable to move said second cylindrical member between said first and second locations to cause said second cylindrical member to engage said tape against said first cylindrical member when actuated in a first direction and to become disengaged from said tape and clear said magazine when actuated in a second direction.
-
3. A magnetic transducing apparatus in accordance with claim 2 wherein said lineal actuator comprises a solenoid.
-
4. A record tape transducing apparatus comprising in combination:
- a magazine containing record tape and including supply take-up means for a length of elongated record tape, said magazine having side walls and end walls surrounding said tape, an opening in an end wall of said magazine, means for guiding a portion of said tape in a fixed path past said end wall opening, a first cylindrical member rotatably supported behind said portion of said tape which is guided in said fixed path, a second cylindrical member, a scanning transducer, a common support for supporting said second cylindrical member and said scanning transducer, a base having means for removably supporting said magazine at a location therein whereby said second cylindrical member and said scanning transducer are in direct alignment with said end wall opening in said magazine, means for guiding said common support in movement towards and away from said magazine along a path wherein said scanning transducer may be operably positioned with respect to said portion of said tape disposed at said end wall opening from a distance away from said magazine wherein said transducer is out of operative relation with said tape of said magazine, means for driving said common support from a first location wherein said second cylindrical member is out of operable contact with said tape and is disposed away from said magazine to a second location wherein said second cylindrical member is engaged against said tape and forces said tape against said first cylindrical member, and wherein said scanning transducer moves with said common support towards said magazine and becomes operatively disposed for scanning said portion of said tape aligned with said opening in said end wall of said magazine, and means for power rotating one of said first and second cylindrical members when said first and second cylindrical members are engaging said tape therebetween to drive said tape between said supply and said take-up means.
