運動の力に動作し回転するものである。(Operation) The present invention uses the principle of an ultrasonic motor using vibrations excited by an ultrasonic vibrator. As is well known, an ultrasonic motor uses a piezoelectric ceramic vibrator or the like to generate a traveling wave or a standing wave that combines longitudinal and transverse vibrations in an elastic body, and causes an elliptical motion on the surface of the elastic body as the movement of a mass point. ,
The rotor, which is pressed against the elastic body, is rotated by the force of the elliptical motion.

できるように圧電セラミック素子が接合される。In the present invention, a pressing member is placed on the surface of an elastic body where elliptical motion is excited. The pressing member is supported by a spring, a slider guide, or a fulcrum so that it can reciprocate along the direction of the elliptical motion generated on the surface of the elastic body. Further, a piezoelectric ceramic element is bonded to the pressing member so as to be movable toward the surface of the elastic body.
このような構成で弾性体と押付部材の間に紙を挾み、前
記楕円運動の動作と、圧電セラミック素子による押付部
材の紙への圧接を同期することにより紙が送行される。With this configuration, the paper is sandwiched between the elastic body and the pressing member, and the paper is fed by synchronizing the elliptical movement and the pressing of the pressing member against the paper by the piezoelectric ceramic element.

At this time, the paper is fed in the direction of the elliptical motion on the elastic body due to the frictional force with the elastic body, and the pressing member is also simultaneously fed due to the frictional force with the paper.

る。On the other hand, when the elliptical motion is in a lower semicircle, the pressing member is released from being pressed against the paper. At this time, the elliptical motion is a movement in the direction of returning the paper to its original position, but since there is no pressing force acting on the paper, the paper may stop due to slippage with the elastic body, or be fed back by a slight inertia force of the paper itself. I would like to be sent to Further, the pressing member returns to its original position by the return force of a spring or the like when the pressure contact with the paper is released. Next, when the elliptical motion is in the upper semicircular state, the pressing member presses the paper and the paper is fed.

is a schematic cross-sectional view for explaining the principle and operation, Figure 1 (
C) is a schematic perspective view for explaining the pressing member, and FIG. 1(d) is a schematic perspective view of the paper feeding mechanism. Figure 1 (
In a> and (b), a piezoelectric ceramic element (hereinafter referred to as an excitation element 12) as an excitation source is bonded to the elastic body 11, and due to the excitation of the excitation element 12, longitudinal vibration is generated in the elastic body 11. and causes lateral vibration. These vibrations are generated by a plurality of excitation elements 12, and by exciting each excitation element 12 with a phase difference, a traveling wave is generated in the elastic body 11. A standing wave is generated by exciting the elastic body 11 including the elastic body 12 by resonance. In both the traveling wave and standing wave types, an elliptical motion 13 can be generated as a mass point motion on the surface of the elastic body 11 due to the combination of longitudinal vibration and transverse vibration. A paper 14 is placed on the elastic body 11, and a pressing member 15 is placed on top of it. The pressing member 15 is supported by a slider mechanism 16 so that there is a gap between the pressing surface 17 of the pressing member 15 and the paper 14, and is placed at a predetermined position by a return spring 18. Furthermore, a piezoelectric ceramic element (hereinafter referred to as one pressure contact element) is bonded to the pressing member 15, and the pressure contact surface 17 is formed into a thin plate so that it can be elastically deformed by the excitation of the pressure contact element 19. In such a configuration, the excitation of the excitation element 12 causes an elliptic motion 1 on the surface of the elastic body 11.
3 is occurring, one pressure contact element is excited at the upper semicircle of the locus of the elliptical motion 13, and the pressure contact surface 17 of the pressing member 15 is convex downward, that is, in a state in which it presses against the paper 14. Become. Due to this pressure contact, the elliptical motion 13 is transmitted to the paper 14 due to the frictional force with the elastic body 11, and the paper 14 is sent in the direction of arrow A. Further, at this time, the pressing member 15 is sent in the same direction of arrow B as the paper 14 due to the frictional force with the paper 14. On the other hand, when the motion trajectory of the elliptical motion 13 is in the lower semicircle, the elliptical motion 13 returns the paper 14 to its original position, but the amplitude becomes negative and the pressing force on the paper 14 becomes small, so the paper 14 does not return to its original position.・It doesn't melt. Moreover, by releasing the excitation of the pressing element 19, the pressing member 15 is released from pressing against the paper 14 and returns in the direction of arrow C by means of the return spring 18. By repeating such operations, the paper 14 is fed by the elliptical movement 13 generated on the surface of the elastic body 11 and the pressing force of the pressing member 15.

An elliptical motion 13 is generated on the surface of the elastic body 11. A paper 14 is placed on the elastic body 11, and a pressing member 15 is supported by a slider mechanism 16 on top of the paper 14. placed in a predetermined position.
