  • Patent number: 5792017
    Abstract: A video cassette recorder comprises a power transfer apparatus provided with a timing belt, a capstan motor pulley and a driven belt pulley. The capstan motor pulley includes a first contact body fixed to a capstan motor shaft of a capstan motor and adapted to be contacted with the timing belt, a first fixed guide plate integrally formed on one principal plane of the first contact body facing toward the capstan motor, and a first guide cap detachably mounted on the other principal plane of the first contact body, in order to prevent the timing belt from deviating from the first contact body. The driven belt pulley has a second contact body contacted with the timing belt, a second fixed guide plate integrally formed on one principal plane of the second contact body located in a same direction as the first fixed guide plate, and a second guide cap detachably mounted on the other principal plane of the second contact body in order to prevent the timing belt from deviating from the second contact body.

  • Patent number: 4227610
    Abstract: A curved belt conveyor having a generally planar ring shaped belt supported and guided for movement along a closed path of travel having first and second generally parallel, spaced apart runs with an inner peripheral edge of the belt substantially defining an arc of the circle about a predetermined center. In accordance with the present invention, the inner peripheral edge of the belt is engaged by a plurality of guide rollers, each of which is mounted for individual independent movement radially of the arc described by the inner peripheral edge. The rollers are resiliently biased radially outwardly against the edge of the belt.
