A stationary record player is described having a turn table adapted to be rotatably driven by an electric motor. A pickup is pivotally secured to the turn table, the pickup having a stylus which moves along the recording groove of a stationary record medium when the pickup is rotated together with the turn table whereby the signal on the record medium is reproduced. The record player comprises a lift member adapted to detect the arrival of the stylus at the final position of reproduction, the lift member including a lift lever being pivoted to the turn table. One end of the lift lever is held by the pickup until the pickup reaches a final inward position whereby the one end is released allowing the remaining end of the lift lever to be pivoted upward. A play lever for operating a switch for supplying current to the electric motor is locked during play, and when the stylus reaches the final playing position, an activating arm of the locking mechanism is moved by the remaining end of the lift lever to release the lift lever stopping the electric motor.
A stationary record player having a turn table adapted to be rotatively driven by an electric motor or the like, and a pickup pivotally secured to said turn table, said pickup having a stylus adapted to move along the recording groove in a stationary record medium when said pickup is rotated together with said turn table, so as to reproduce the signal on said record medium, characterized by comprising a lift member adapted to detect the arrival of said stylus at the final position of reproduction, said lift member including a lift lever being pivoted to said turn table, one end of said lift lever being held by the pickup until the pickup reaches a final inward position whereby said one end is released allowing the remaining end of said lift lever to be pivoted upward;
A stationary record player having a turn table adapted to be rotatively driven by an electric motor comprising:
A stationary record player having a turn table adapted to be rotatively driven by an electric motor or the like, and a pickup pivotally secured to said turn table, said pickup having a stylus adapted to move, as said pickup is rotated together with said turn table, along a recording groove in a stationary record medium so as to reproduce the signal recorded in the latter, characterized by comprising a pickup support by which said pickup is pivotally supported, a spring associated with said pickup support so as to normally bias said pickup toward the outer side of said turn table, and a sector-like tab formed on said pickup support;
A stationary record player having a turn table adapted to be rotatively driven by an electric motor, and a pickup pivotally secured to said turn table, said pickup having a stylus adapted to be moved as said pickup is rotated together with said turn table, along the recording groove in a stationary record medium, so as to reproduce the signal recorded in said record medium, characterized by comprising a play lever disposed movably and biased in one direction for operating a switch for energizing said motor, a locking mechanism adapted to lock said play lever in a playing state as said play lever is depressed against the biasing force and to release said play lever as the latter is subsequently depressed so as to allow said play lever to be reset to the initial state, and a reversing transmission mechanism coupled to the play lever for providing mechanical motion reverse to the motion experienced by said play lever, and means for raising and lowering said pickup onto the surface of said record medium comprising a lift plate and see-saw member, said lift plate being located vertically above said pickup and see-saw member, said lift plate being coupled to said transmission whereby when said play lever is locked in the playing state said lift plate is raised and said see-saw member releases said pickup whereby said pickup is lowerred, and said pickup is raised away from said surface of said record medium by the lowering of said lift plate into contact with said see-saw member which forces said pickup to pivot as said play lever is reset to said initial state by said locking mechanism.
A stationary record player having a turn table adapted to be rotatively driven by an electric motor or the like, and a pickup pivotally secured to said turn table, said pickup carrying a stylus adapted to be moved, as said pickup is rotated together with said turn table, along the recording groove in a stationary record medium, so as to reproduce the signal recorded on the latter, characterized by comprising a lift member pivoted to said turn table having a first end which is held in a first position by said pickup, said one end being released by said pickup at the final position of reproduction whereby a second end of said lift member is pivotally brought into contact with a means for inhibiting the driving of said turn table.
