Abstract

Abstract Capstan, which engages the tape in a cassette, is directly mounted on the capstan motor shaft. Spindles which engage the reels in the cassette are directly mounted on the shafts of two separate torque motors, one or the other of which is energizable to wind tape on one reel and unwind it from the other. A U crosssection motor mounting frame has a forward upright wall in the front panel of the transport housing, and a rearward upright wall spaced behind it within the housing. The capstan motor is fastened to the back side of the rearward wall and has an elongated shaft extending through both walls and terminating in a capstan on the front side of the forward wall. The capstan motor has an elongated bearing supporting the shaft adjacent the capstan. The torque motors are fastened to the back side of the forward wall and have spindle shafts extending through that wall. The torque motors are disposed between the forward and rearward walls, alongside the capstan elongated shaft, forward of the capstan motor, and within the axial projection of the capstan motor.
