The paper stored in the paper is fed out one by one from the lower side by the above-mentioned conveying means. However, if the sheets of paper stored in the paper storage section are in close contact with each other.
用紙が２枚同時に送られる所謂る重送などの不具合が生
じる。Problems such as so-called double feeding, where two sheets of paper are fed at the same time, occur.
発明の目的

ている。Embodiment The present invention will be described in detail below with reference to an illustrated embodiment.
In the figure, S denotes a paper storage section that stores sheets 2 to be transported in a stacked state, and a paper ejection means 4 such as a vacuum feeder is provided below a paper ejection port 3 of this paper storage section 1.

擦抵抗を低減するようになっている。On the other hand, above the paper outlet 3 of the paper storage section 1, a separation means 8 is provided that blows air toward the end surface of the paper 2 stored in the paper storage section 1. The separation means gi;i
It is connected to an air pressure supply source (not shown), and the air supplied from this air pressure supply source is ejected from a nozzle hole 8α formed diagonally downward. Further, a valve (not shown) is provided between the separating means 8 and the air pressure supply source and is opened for a certain period of time immediately before the conveying means 4 starts conveying the paper 2. When this valve is opened, Air adjusted to a pressure suitable for separating the paper 2 is ejected from the nozzle hole 8a toward the end surface of the paper 2. Then, the air ejected from the nozzle hole 8α enters between each paper 2 and separates each paper 2, and at the same time forms an air layer between each paper 2, causing electrostatic adsorption between each paper 2. The force is weakened to reduce frictional resistance.
なお用紙収納部１へ収容された用紙２が薄手で軽い場合
、分離手段ｇより空気を噴出すると。Note that when the paper 2 stored in the paper storage section 1 is thin and light, air is ejected from the separating means g.
