Abstract

PURPOSE:To perform reliable operations to separate a paper and to assume a posture of a paper supply irrespective of a paper thickness, by constituting a feeder such that a separating member, whose coefficient of friction is smaller than that of a puckup roller for a copying machine and larger than that of a paper, is brought into contact with the pickup roller, and a supply means is located in the proximity of a separating member. CONSTITUTION:The papers P, pressed against a pickup roller 2 by a spring, are picked up by the pickup roller 2 to convey it in a direction B. If the papers P happen to be supplied in an overlapping manner, since a coefficient of friction of a member 7 for preventing a plural number of papers from simultaneous delivery is smaller than that of the pickup roller 2 and larger than that of the paper P, the papers other than the paper, contacting the pickup roller 2, are slipped between the papers and are held by the preventing member 7 to check advancing of them. Thus, only the paper at the pickup roller (2) side is separated for supply, and is immediately supplied between the nip formed by the roller 2 and a feed roller 12. This constitution prevents the papers from being supplied in a tilting manner, and causes them to be normally held in a correct posture and be separated irrespective of a paper thickness.

Description

DETAILED DESCRIPTION OF THE INVENTION The F1 scrap paper machine klllL of the present invention, in particular, the paper feeder tIcWR that feeds paper sheets one by one into the next process sK.

Optical character reader, *011'lK or ￇ$+
After supplying and conveying 1 m, a certain - is placed in the conveying process,
In order to read fairy characters using the improved character reading theory and to make copies using the II copying mechanism, a paper feeding device was designed to automatically supply paper products. Ru.

A conventional paper feeding device, as shown in FIG. 1, for example, has a hopper 1 that horizontally stacks a large number of new leaves 11P', and a pickup roller 2 that takes out the paper leaves 11P loaded in the hopper 1. More specifically, the hopper l#i is supported by a mechanism 97) (not shown) so that the uppermost layer of papers P loaded on the hopper 1 always hangs constant. As a result of this, the pickup/fourer 2 always comes into contact with the paper sheet 1fP with a constant pressure. At both corners @IIC of the tip of the hopper 1, claws 3 are provided to prevent multiple sheets of paper ll1lp from being fed out. The pickup/driver 2 shown in the figure is driven by a drive device 1 and is intermittently rotated in the direction of the arrow. Further, 4.4' is a feed field-ra pair that sends out the paper 1111F taken out from the hopper 1.

This 0. In the @ position, as the pickup 2 rotates in the direction of the arrow mark, the paper **P has a large deflection> 1 to the claw 3 that locks both corners of its leading edge. As the turtle moves in the direction of the arrow 15, it is trying to prevent the above-mentioned ``Ewami JPK''. Paper feed f
In this case, the power controller m at position 30, which prevents the dispensing from being fed out, is on the uppermost position, and the claw 8 is in the correct position. It is impossible to explain the theory at the beginning of the paper.
When IIIF is sent out in a slanted shape (in the same layer), the above "*Wami" in the paper sheet order PO is 11PC1.
m111 (IF, strange waist, etc.) Because it is more exciting than k,
There is also the problem that it is possible to evaluate 1 * ll 0 Ifc y y f c y y f c y y y y y y y y y y y y y y y y y y y y y y y y device.
II tube glued - so-called "comparison sheet" etc.)
When trying to feed paper 11, this device feeds paper 11 as in previous t.
In order to reduce the "1@Kr deflection", only the topmost 0w1 paper of the multi-part paper is separated and fed, so it cannot be used to feed such multi-part paper. Friends who have problems.

The present invention has been made in view of the above circumstances, and its purpose is to eliminate the above-mentioned problem of the conventional paper feeding device, to have a simple mechanism, and to provide paper sheets with an inclined shape when fed. It is easy to exhibit lI, and it is thin to thick type.
To provide a paper feeder that reliably feeds @ sheets one by one and also makes it possible to feed multiple sheets of paper one by one.

In the above-mentioned Diahan of the present invention, there is a hopper for loading paper**, a means for taking out the paper *a tube that has been packed into the hopper, and a means for sending the paper S* taken out by the taking-out means to the next process. In the paper feeding device F having the above-mentioned expenditure hand Rk
A member is provided to prevent the number of sheets from being fed out by applying approximately constant pressure.
The friction coefficient of the paper 11 is as follows:
1it:s has a large friction coefficient, which is achieved by making the delivery hand pt - the plurality of sheet feed-out prevention member rim by %, when the delivery hand is made of a material with a smaller friction coefficient than the delivery hand fejl.

Hereinafter, a detailed explanation will be given based on one example of the zero-fire [611m1] drawing.

A pick-up roller 2 is provided for sending out the test paper leaf IIP by contacting the surface of the tip of the test paper IIP. The surface of the pickup is made of a material that has a friction coefficient that is sufficiently large compared to that of the paper industry (a), and both ends (not shown) are capable of KIN rotation. It is supported in an inverted position, and one end thereof is connected to the drive device 6.

Further, a plurality of paper sand and unwinding prevention members 7 are provided immediately before the contact portion between the tip of the paper and the pickup reeler 2. The friction coefficient of the paper sheet IIP is 7JS.

A feed roller 12 having a moxibustion concave portion arranged in a shape is disposed. I11! roller 12 is driven by spring 13),
It is supported so as to always come into contact with the pickup roller 2 with a substantially constant force.
