摘要： A compact drive mechanism for a tape recorder enabling the recorder to rapidly drive tape in a forward or a reverse direction or at a slower record and playback speed. The drive mechanism includes a motor having a double-ended drive shaft. A pair of friction clutch means is connected to forward and reverse tape-driving spindles of the recorder for selective coupling to opposite ends of the drive shaft to effect the rapid forward and reverse tape drive. A transmission means connects between one end of the drive shaft and the capstan of the recorder to turn the capstan at the record and playback speed. This occurs when the friction clutch couples the forward tape-driving spindle to the drive shaft. Thus, when the pinch roller of the recorder is engaged, the capstan drive overrides the clutch means of the forward tape-driving spindle causing it to slip and tape to be driven from a reel on the reverse tape-driving spindle to a reel on the forward tape-driving spindle at the playback and recording speed.

摘要： A plug and socket connection includes helical guides at the socket for guiding mating helical pins on the plug through orifices to connection contacts protected by the orifices in the socket. The projection of each helical guide about the socket axis subtends an angle that is substantially equal to 360.degree. divided by the number of helical guides.
