が防止される。2. Description of the Related Art Conventionally, there is known a sheet feeding device capable of sequentially feeding a plurality of stacked originals and the like one by one (Japanese Patent Laid-Open No. 59-533).
No. 34). FIG. 5 shows a sheet feeding device 50 of this type. In the figure, reference numeral 51 is a tray on which a plurality of sheets P such as originals can be set, a paper feed mechanism 52 is arranged above the tray 51, and a double feed prevention mechanism 53 is arranged in the front. To do. The paper feed mechanism 52 is provided with a paper feed roller 55 which is biased by a spring 54 and presses against the upper surface of the paper P ..., On the other hand, the double feed prevention mechanism 53 is arranged on the upper side and a lower roller 56. A fixed roller 57 is provided. Therefore, when the paper feeding roller 55 is rotated, the papers P set on the tray 51 are sequentially fed one by one from the top between the rotary roller 56 and the fixed roller 57, and the fed paper P is rotated. Is transferred further forward. At this time, when two or more sheets are fed, the fixed roller 57 prevents the double feeding of the sheets P ... Other than the uppermost sheet.
ところで、このような従来の給紙装置50は、送紙機構
52と重送防止機構53の二つの機構が独立し、かつ個別に
機能するため、特に紙のセッテイング機構の構造が複雑
となり、大型化と高コスト化を招く不具合があった。By the way, such a conventional paper feeding device 50 has a paper feeding mechanism.
Since the two mechanisms, 52 and the multi-feed preventing mechanism 53, are independent and function individually, the structure of the paper setting mechanism is particularly complicated, resulting in an increase in size and cost.
本発明はこのような従来技術に存在する不具合を解消

Is set obliquely from above between the paper feeding roller 2 and the double feed prevention roller 3, and the paper P ... 4 and the paper feed roller 2 are guided in a substantially tangential direction. At this time, the set papers P are brought into pressure contact with the paper feed roller 2 by the pressing action of the pressing member 4. Therefore, when the roller 2 rotates, the top paper P in contact with the roller 2 is fed. Be seen. At this time, even if a plurality of sheets of paper P ... Are fed, the double feed prevention roller 3 does not rotate in the paper feed direction of the paper P, so the paper P in contact with the double feed prevention roller 3 remains stagnant. In the end, only the separated top paper P is fed. In this way, the paper feed roller 2 has both a paper feed function and a double feed prevention function, and the curved pressing member 4 is formed.
Presses the paper P ... to the paper feed roller 2 to assist the paper feeding function.
