トが上がるなどの不具合があった。Problems to be Solved by the Invention However, in the case of sheets that are charged with static electricity, the sheets are attracted to each other by the static electricity, so even when air jets are blown onto the sheets, the sheets are not separated, resulting in double feeding. Conventionally, this was dealt with by increasing the pressure of the air jet, but
This method required a high-pressure air source, which led to problems such as increased costs.
この発明は上記不具合を改善する目的でなされたもので
おる。This invention was made for the purpose of improving the above-mentioned problems.

In the drawing, 1 is a main body of a paper feeding device provided in a copier or the like (not shown), which has a paper storage section 2 with an inclined bottom surface. The paper 3 is stored in the paper accommodating section 2 in a stacked state. Note that 2a is a guide for aligning the edges of the paper 3.

The vacuum conveying means 4 includes a pair of rollers 51 which are spaced apart in the conveying direction, a conveying belt 6 wrapped around VIK, and a vacuum suction means 7 which sucks the paper 3 in the paper storage section 2 and presses it against the conveying belt 6. The paper 3 sucked by the vacuum suction means 7 and fed out by the conveyor belt 6
is conveyed by conveyance rollers 8.

ている。On the other hand, reference numeral 9 denotes an air nozzle installed on the paper feeding side of the paper storage section 2, and is installed so as to eject an air jet toward the end surface of the paper 3. Further, the base end side of the air nozzle 9 is connected to the discharge side of the air blowing means 11 via a conduit 10. The blowing means 11 is, for example, a blowing fan, and an AC corona discharger 12 is provided on the suction side. A high-voltage power source 13 is applied to the AC corona discharger 12 to cause corona discharge, and the ion flow generated at this time is sent to the air nozzle 9 along with air by the blowing means 11.
Air is ejected from the air nozzle 9 toward the paper 3.

ンも図れるようになる。Effects of the Invention As described in detail above, this invention spreads the paper 3 by ejecting an air jet containing ions from the air nozzle 9 installed on the paper feed side of the paper storage section 2. Even if three comrades are attached to each other, the static air is removed by the ions, so that the sheets 3 can be handled reliably. This makes it possible to prevent the paper 30 from being fed in duplicate, and since there is no need to blow out high-pressure air, the blowing means 11 can also be made smaller, thereby reducing costs.
