（２）モータの駆動力を第１ギア、第２ギア、第３ギア
により伝達するため駆動力の損失が多い。(2) Since the driving force of the motor is transmitted through the first gear, second gear, and third gear, there is a large loss of driving force.
（３）駆動力にモータを使用しているため消費電力が大
きい。(3) Since a motor is used for driving force, power consumption is large.
（４）モータ駆動時に騒音が発生する。(4) Noise is generated when the motor is driven.
そこで、本発明の目的は前記問題点を解決すべく小型、
低消費電力、低騒音の紙送シ装置を提供することにある
。Therefore, an object of the present invention is to solve the above-mentioned problems.
An object of the present invention is to provide a paper feeding device with low power consumption and low noise.

。FIG. 1 is a perspective view of the paper feeding amount according to an embodiment of the present invention. In the figure, elements that perform the same functions as those of the conventional paper feeding device shown in FIG. 3 are given the same numbers. The feature of this embodiment is that the motor 14 and the first gear 8, second gear 10, and third gear 12 are not provided outside the chassis 2 as in the conventional case, and the paper feed roller 4 is provided inside the paper feed row 24. The purpose is to provide an ultrasonic motor 20 that drives the.

９０’の角度をなすように４個の超音波モータ２０が固
定される。Figure 2 (,) shows the A-A of the paper feed row 24 in Figure 1.
2(b) is a sectional view taken along line BB'. As shown in FIGS. 2(a) and 2(b), an annular ultrasonic motor holder 22 is fixed to the paper feed roller shaft 6, and four motors are attached to the ultrasonic motor holder 22 at an angle of 90' to each other. ultrasonic motors 20 are fixed.
超音波モータ２０の外側には外周にすベシ止め材２４を
有するプーリ２６を回動可能に設ける。A pulley 26 having a bevel stopper 24 on its outer periphery is rotatably provided on the outside of the ultrasonic motor 20.
該すベシ止め材２４は給紙用紙１６との摩擦を犬、きく
するためのものである。なお超音波モータ２０の駆動電
力は接触端子（図示せず）等の手段によシ供給される。The bevel stopper material 24 is for increasing the friction with the feed paper 16. Note that driving power for the ultrasonic motor 20 is supplied by means such as a contact terminal (not shown).
また超音波モータ２０の個数は４個に限定されるもので
はない。Further, the number of ultrasonic motors 20 is not limited to four.
