Abstract

PURPOSE:To prevent misfeed, by setting a vacuum suction conveyer above a movable tray, as setting a nozzle which faces to the edge of the sheets and can be swayed freely upward/downward, between the said tray and the vacuum suction conveyer, in a sheet conveying device of such as a copying machine. CONSTITUTION:Even if a stepped part B is made at the border-line A4 between the upper sheets A2 and the lower sheets A3, when a sheet conveying device is re-driven after an interval, the sheets can be conveyed one by one, by blowing air sufficiently against the edge A' of the upper/lower sheets A of the stepped part B through a nozzle 3 which is swayed upward/downward, floating these sheets, and sucking and conveying the sheets by a vacuum suction conveying system. In this way, a misfeed can be prevented.

２に吸着して給送する装置。BACKGROUND ART As shown in FIG. 3, a vacuum suction type belt conveyance mechanism 2 is provided above a movable tray 1 that moves up and down, and a nozzle 3 is installed between the vacuum suction type belt conveyance mechanism 2 and the movable tray 1. The nozzle 3 is placed facing the edge X of the paper sheet, and as shown in FIG. A device that adsorbs and feeds the transport mechanism 2.

ミスフィードの原因となる。Problem to be Solved by the Invention Since the movable tray 1 moves upward at every fixed stroke, when feeding a predetermined amount (thickness) of paper as shown in FIG. Air is not blown onto the sheet of paper, and a step B is created at the boundary A4.
This prevents sufficient air from being blown onto the paper.
This may cause misfeeds.

の。Means to solve the problem and operation The nozzle is swingable up and down, and when it is stopped and restarted, sufficient air can be blown above and below the stepped part to prevent misfeeds. What made it possible.

It is pressed against an eccentric cam 5 with a spring 6, and by rotating the eccentric cam 5, the nozzle 3 is moved to the bin 4. It swings up and down within a predetermined angle range around .

なお、真空吸着式搬送機構２は真空源に連通し、かつ孔

る。Because of this, when feeding is stopped and then driven again to feed, there is a step B at the boundary A4 between the upper paper A and the lower paper A8, as shown in Figure 2. However, by swinging the nozzle 3 up and down, sufficient air can be blown to the edges of the paper sheets above and below the step B, so that the paper sheets can be reliably lifted and misfeeds can be prevented. .

せることができ、ミスフィードの発生を防止できる。Effects of the Invention Even if there is a step between the upper and lower paper sheets when the paper is driven and fed again after being stopped once, the nozzle 3 is swung up and down to sufficiently blow air to the edges of the upper and lower paper sheets at the step. This can prevent misfeeds from occurring.
