Abstract
PURPOSE: To make possible miniaturization by making use of a device of a contact winding system as a subminiature type home video camera.
CONSTITUTION: When a cassette 1 is inserted into a VTR driving device 31, a steel ball 32 fits into the meshing hole 19 of the clutch disc 18 of the under surface of the cassette. The rotation of a motor 35 it transmitted to a capstan 13 which rotates a pair of right and left tape rolles, the outside circumferences of which are press-contacted with the outside circumference of the capstan by means of bias springs 12, freely forward and backward. In order to apply tape tension, the take-up side contact pressure is made larger than the supply side contact pressure, but the friction force generated in a friction member 7 is made the rotating resistance of an arm extending the bias springs 12, whereby the differential pressure is generated with the simple mechanism.
