Translating machine

Claim 2

An audio-reproducing machine for reproducing selected messages comprising: a frame, a recording medium comprising magnetic tape formed into an endless belt and formed with a plurality of soundtracks formed side by side thereon, a playback head supported by the frame and movable transversely of the recording medium to engage a selected soundtrack, a guide means comprising a slot attached to the frame, a guide follower mounted on said guide means and said playback head mounted on said guide follower and indexing means mounted adjacent said guide follower to allow the playback head to be indexed relative to said recording medium, a knob with a pointer attached to said guide follower to move said guide follower and said indexing means, driving means mounted on said frame and moving said magnetic tape relative to said playback head, a reproducer connected to said playback head, a start and stop circuit for said driving means, stop means comprising an electrical conductive area associated with the start and stop circuit for stopping said driving means and formed on said tape for stopping said driving means each time a selected sound track has been reproduced, a portion of said start and stop circuit for said driving means comprising a pair of wiper contacts supported by said frame and engageable with the electrical conductive area, a pair of rollers mounted on parallel axes from said frame and adapted to receive said endless belt thereon and said driving means coupled to said one of said rollers to drive said belt, means for moving said rollers relative to each other to allow mounting and driving of the belt comprising a shaft rotatably supported by said frame, one of said rollers supported eccentrically by said shaft, and a control lever attached to said shaft and movable to run and load positions.

Claim 3

An audio-reproducing machine according to claim 1 wherein said electrical conductive area is formed by attaching conductive foil to said magnetic tape.

Claim 4

An audio-reproducing machine for reproducing selected messages comprising: a frame, a recording medium comprising magnetic tape formed into an endless belt and formed with a plurality of soundtracks formed side by side thereon, a playback head supported by the frame and movable transversely of the recording medium to engage a selected soundtrack, a guide means comprising a slot attached to the frame, a guide follower mounted on said guide means and said playback head mounted on said guide follower and indexing means mounted adjacent said guide follower to allow the playback head to be indexed relative to said recording medium, a knob with a pointer attached to said guide follower to move said guide follower and said indexing means, driving means mounted on said frame and moving said magnetic tape relative to said playback head, a reproducer connected to said playback head, a start and stop circuit for said driving means, stop means comprising an electrical conductive area associated with the start and stop circuit for stopping said driving means and formed on said tape for stopping said driving means each time a selected sound track has been reproduced, a portion of said start and stop circuit for said driving means comprising a pair of wiper contacts supported by said frame and engageable with the electrical conductive area, a pair of rollers mounted on parallel axes from said frame and adapted to receive said endless belt thereon and said driving means coupled to said one of said rollers to drive said belt, means for moving said rollers relative to each other comprising a cylinder, one of said rollers rotatably supported on said cylinder, a lever with one end pivotally attached to the cylinder and an intermediate point of said lever pivotally attached to the frame, and spring-biasing means between said lever and the frame to bias the one roller away from the second roller.

Claim 5

An audio-reproducing machine for reproducing selected messages comprising: a frame, a recording medium comprising magnetic tape formed into an endless belt and formed with a plurality of soundtracks formed side by side thereon, a playback head supported by the frame and movable transversely of the recording medium to engage a selected soundtrack, a guide means comprising a slot attached to the frame, a guide follower mounted on said guide means and said playback head mounted on said guide follower and indexing means mounted adjacent said guide follower to allow the playback head to be indexed relative to said recording medium, a knob with a pointer attached to said guide follower to move said guide follower and said indexing means, driving means mounted on said frame and moving said magnetic tape relative to said playback head, a reproducer connected to said playback head, a start and stop circuit for said driving means, stop means comprising an electrical conductive area associated with the start and stop circuit for stopping said driving means and formed on said tape for stopping said driving means each time a selected sound track has been reproduced, a portion of said start and stop circuit for said driving means comprising a pair of wiper contacts supported by said frame and engageable with the electrical conductive area, a pair of rollers mounted on parallel axes from said frame and adapted to receive said endless belt thereon and said driving means coupled to said one of said rollers to drive said belt, means for moving said rollers relative to each other comprising a cylinder, one of said rollers rotatably supported on said cylinder, a lever with one end pivotally attached to the cylinder and an intermediate point of said lever pivotally attached to the frame, and spring-biasing means between said lever and the frame to bias the one roller away from the second roller.
