    摘要: In a vibration wave driven motor, an elastic body of an elliptic shape is provided where different degrees of stiffness or rigidity are available with the arcuate portions and the straight portions, and the ratio between the distortion energy and the vibration energy that part in the generation of the natural frequency for the A vibration mode is arranged virtually equal to that ratio for the B vibration mode, thus enabling the matching of frequencies for both A and B modes.

    摘要: In a vibration wave driven motor, when the radius of the arcuate portions and the length of the straight portions of a track type resilient member of an elliptical shape having straight portions and arcuate portions are (R) and (L), respectively, the ratio (R/L) is made equal to or greater than a particular value, whereby the resonance frequencies of two standing waves can be made coincident with each other and the torsion component of the straight portions can be reduced or the direction of the torsion can be made uniform with a result that the driving characteristic in the straight portions can be improved and also the electrode pattern of a piezo-electric element can be simplified.

    摘要: In a vibration wave driven motor having a vibration member having an electro-mechanical energy conversion element secured to one surface of a resilient member of an elliptical shape formed by straight portions and arcuate portions, and a member brought into pressure contact with the other surface of the resilient member and wherein AC voltages having a phase difference of 90.degree. therebetween in terms of time are applied to the driving phases of the electro-mechanical energy conversion element divided into two phases to thereby generate a travelling vibration wave in the resilient member, whereby the vibration member and the member brought into pressure contact therewith are moved relative to each other, the two driving phases of the electro-mechanical energy conversion element are polarization-processed in such a manner that only one travelling wave is formed in the straight portions of the resilient member.

    摘要: A vibration driven motor has a rail-like stator secured to a bottom plate and a vibration member for generating a travelling vibration wave in an elastic member to which an electro-mechanical energy conversion element is fixed due to an application of AC electric field to the electro-mechanical energy conversion element so as to bring a portion of the elastic member into press-contact with the rail-like stator. In the vibration driven motor a surface area of the bottom portion of the rail-like stator which comes in contact with the bottom plate is less than the a surface area of the top portion of the rail-like stator.

    摘要: A printing apparatus is provided. A vibrator comprising an elastic member and an electric/mechanical energy converting device jointed to the elastic member is attached to a carriage on which a printing head is mounted. The vibrator generates a progressive vibrating wave. The vibrator is partially come into frictional contact with a rail-shaped stator and moves along the rail-shaped stator by the progressive vibrating wave. An object to be driven is frictionally come into contact with a portion of the vibrator which is not in contact with the rail-shaped stator. The object to be driven is driven by the progressive vibrating wave. By providing a motion converting mechanism for the carriage, driving operations other than the carriage feeding operation are also executed by the vibrator.
