Abstract
A tape player/recorder device for a tape cassette includes a winding reel driven by a capstan motor through a tumbler gear. The shaft of the motor is outside of the cassette. The tape player/recorder device also includes a plurality of threading elements, an idler roller, a plurality of threading elements and a threading motor for threading the tape into the player/recorder. A planet gear is responsive to the capstan motor and is in engagement with the tumbler gear. A slip coupling enables the selective by-passing of the planet gear.

In a tape player/recorder device for a tape cassette having at least one winding reel driven by a capstan motor through a tumbler gear, the shaft of said motor being outside said cassette, a plurality of threading elements, an idler roller, and a threading motor for threading a tape in said player/recorder, an improvement comprising:
- a planet gear coupled to said capstan motor and in engagement with said tumbler gear;
- and,
- a controllable slip coupling for selectively by-passing said planet gear.
In a tape player/recorder device for a tape cassette having at least one winding reel driven by a capstan motor through a tumbler gear, the shaft of said motor being outside said cassette, a plurality of threading elements, an idler roller, and a threading motor for threading said tape in said player/recorder, an improvement comprising:
- a planet gear responsive to said capstan motor and in engagement with said tumbler gear;
- a slip coupling for selectively by-passing said planet gear wherein said slip coupling is controllable;
- and
- a lever and control means responsive to said threading motor for controlling said slip coupling through said lever.
A tape recording and replay apparatus comprising:
- a reel platter for winding a tape;
- a capstan motor and a drive shaft for driving said tape;
- a tumbler gear for driving said reel platter;
- a planetary gear coupled to said tumbler gear and driven by said capstan motor;
- and,
- a controllable slip coupling coupled to said planetary gear for varying drive torque between said capstan motor and said tumbler gear.
A tape recording and replay apparatus comprising:
- a reel platter for winding a tape;
- a capstan motor and a drive shaft for driving said tape;
- an idler wheel for urging said tape against said drive shaft;
- a tumbler gear pivotally mounted for driving said reel platter;
- a planetary gear coupled to said tumbler gear and driven by said capstan motor;
- and,
- a controllable slip coupling being controlled to pivot said tumbler gear for driving a second reel platter.
