摘要： The invention provides a paper supply apparatus for an image reading apparatus, an image reading apparatus with a paper supply apparatus and a paper supply apparatus which can be used suitably with an image scanner wherein a large amount of paper sheets can be taken out one by one with certainty and read successively and rapidly. The paper supply apparatus successively supplies paper sheets accommodated therein to a paper transport mechanism along which an optical image reading mechanism is disposed, and comprises a paper supply hopper, a paper supply roller located above the paper supply hopper for forwarding the paper sheets accommodated in the paper supply hopper, a paper supply roller driving mechanism for rotating the paper supply roller, and a paper separation mechanism for preventing two or more paper sheets forwarded by the paper supply roller from being sent to the paper transport mechanism. The paper separation mechanism includes a paper skew prevention mechanism for holding down a passing paper sheet with a higher paper holding down force at a central location in the widthwise direction of the paper sheet but with lower paper holding down forces at the opposite end locations in the widthwise direction of the paper sheet.
摘要翻译：本发明提供一种用于图像读取装置的供纸装置，具有供纸装置的图像读取装置和可以与图像扫描器适当地使用的供纸装置，其中可以逐个取出大量的纸张确定性，依次快速阅读。供纸装置将容纳在其中的纸张依次供给到设置有光学图像读取机构的纸张传送机构，并且包括供纸料斗，位于纸供给料斗上方的供纸辊，用于将容纳在供纸斗，用于使供纸辊旋转的供纸辊驱动机构，以及用于防止由供纸辊转送的两张或多张纸张被送到纸张传送机构的分纸机构。纸张分离机构包括纸张偏斜防止机构，用于在纸张的宽度方向上的中央位置用较大的纸张张紧力按压通过的纸张，但是在纸张的相对端部处具有较低的纸张压力纸张宽度方向。

摘要： A flash lamp fixing with a simple structure, capable of obtaining an even distribution of high-level luminous energy over a large area on the surface of a paper sheet illuminated by a flash lamp. In the flash lamp fixing device, the half breadth L.sub.1 of the aperture of the reflector is set so as to satisfy the equation V/T.gtoreq.L.sub.1 .gtoreq.V/T-L.sub.2 /2, where V is the conveying speed of a paper sheet; T is the flash cycle of the flash lamp; L.sub.1 is the half breadth of the aperture of the reflector; and L.sub.2 is the length of an area in which fixing can be done by one flash of the flash lamp. Where .theta..sub.1 represents the included angle between a tangent which passes through one of aperture edges, being tangent to the flash lamp on the side of the aperture and the plane of the aperture; and .theta..sub.2 represents the included angle between a tangent which passes through the aperture edge, being tangent to a safety distance critical circle centered on the center of the flash lamp and a plane normal to the aperture plane, the tilt angles of the respective inclined face parts in relation to the plane normal to the aperture plane are set to be not less than .theta..sub.1 and not more than .theta..sub.2.
