Abstract
A magnetic recording and reproducing system comprises a capstan, reel shafts, a motor for rotatably driving said capstan and said reel shafts, a magnetic tape wound up by the rotation of the reel shafts, a pinch roller for pressing the tape against the capstan, and a drive mechanism for driving said pinch roller into engagement with and disengagement from said capstan by a rotation force of said motor.
Claims13
A magnetic recording and reproducing system comprising a capstan, reel shafts, motor means operative when connected to a voltage source, coupling means for transmitting the rotational force of said motor to said capstan and reel shafts, a pinch roller for pressing a magnetic tape to said capstan, an engagement-disengagement drive mechanism responsive to said coupling means for selectively driving said pinch roller into engagement with and disengagement from said capstan, an electromagnetic plunger operative when connected to a voltage source to cause an initial motion of said engagement-disengagement drive mechanism which serves to couple said coupling means to said engagement-disengagement drive mechanism, and operation switch means for connecting said electromagnetic plunger and said motor to a voltage source, said electromagnetic plunger and engagement-disengagement drive mechanism arranged such that a first operation of said electromagnetic plunger serves to couple said engagement-disengagement drive mechanism to said coupling means to drive said pinch roller into engagement with said capstan and a second operation of said electromagnetic plunger serves to couple said engagement-disengagement drive mechanism to said coupling means to disengage said pinch roller from said capstan.
