Claims
- 1. In a hand-held transducing device for transducing information signals relative to a stationary record carried on a sheet of material, a housing small enough to be readily held in one hand, a transducing assembly within the housing including a rotatable body, transducer means carried by said body during rotation of said body for following a record trace defined on said record, follower means carried by said rotatable body to move with said transducer, stationary guide means lying in a plane disposed in spaced relation from the plane of said sheet of material carried by said housing to define a substantially annular guide path for engaging said follower means to move said transducer along said trace around said record when so engaged, said guide path having a gradually decreasing track spacing at progressively increasingly radially outwardly displaced portions thereof, and means for orienting said transducer to be disposed at progressively smaller angles to said path in response to progressively increased radially outward displacement of said transducer from the innermost track location.
- 2. In a hand-held transducing device according to claim 1 in which said rotatable body carries transducer reset means movable with respect to said body between first and second positions, a portion of said reset means engaging and moving said transducer means in response to movement of said reset means relative to said body.
- 3. In a hand-held transducing device for transducing information signals relative to a stationary record carried on a sheet of material, a housing small enough to be readily held in one hand, a transducing assembly within the housing including a rotatable body, a pivot arm carried by said body and a transducer carried by said pivot arm for following a record trace defined on said record, follower means carried by said rotatable body to move with said transducer, stationary guide means carried by said housing defining a substantially annular guide path for engaging said follower means to move said transducer along said trace around said record when so engaged, and reset means movable with respect to said body between first and second positions for engaging and moving said pivot arm to reset said transducer to a predetermined position on the record.
- 4. In a hand-held transducing device according to claim 3 including means serving to yieldingly retract said reset means from engagement with said pivot arm to permit said pivot arm to enable said transducer to freely advance along said trace.
- 5. In a hand-held transducing device according to claim 3 comprising means for inhibiting rotation of said body in response to operation of said reset means.
- 6. In a hand-held transducing device according to claim 3 further including means yieldingly moving said reset means to said first position after resetting said transducer.
- 7. In a transducing assembly for transducing information signals relative to a stationary record carried on a sheet of material disposed in a plane, said assembly comprising a housing for receiving the sheet, a rotatable body within the housing, a transducer carried to move with said body during rotation of said body and disposed to define an information trace on said sheet, follower means carried by said rotatable body to move with said transducer, stationary guide means lying in a plane and carried by said housing in confronting spaced parallel relation to the plane of the sheet, said guide means serving to define a substantially annular guide path for engaging said follower means to move said transducer along a record trace defined on said record when so engaged, said transducer being disposed between the planes of said sheet and said guide means.
