Abstract

There is disclosed a paper feeder for a copying machine, including a paper feeding tray sub-member having guiding projections and stoppers for properly loading a paper feeding tray, a pivot for pivotally mounting the paper feeding tray sub-member in the position adjacent to a paper guide, a lever mounted on the underside of the paper feeding tray sub-member, and a slanting position fixing member attached to the body of the copying machine for fixing the lever and thus the slanting position of the paper feeding tray sub-member.

Claims

1. A paper feeder accessory for a copying machine, comprising:

a paper feeding tray sub-member having projecting means for guiding a paper tray received by said sub-member and means for stopping forward travel of a paper tray received by said sub-member, for loading a paper feeding tray;

a pivot for pivotally mounting said paper feeding tray sub-member in a copying machine;

a paper guide mounted adjacent to said pivot;

a lever mounted on the underside of said paper feeding tray sub-member; and

a slanting position member attached to a body of said copying machine, for restraining said lever and thus maintaining said paper feeding tray sub-member in a slanting position relative to a horizontal plane.

2. The paper feeder for a copying machine as claimed in claim 1, wherein means for engaging said lever with said slanting position member comprises at least two retaining cuts formed in the periphery of said slanting position member.

3. The paper feeder for a copying machine as claimed in claim 1, wherein said paper guide is curved toward a register roller, so that the papers are smoothly fed to said register roller when said paper feeding try is loaded at upper portion of the body of said copying machine.

4. A paper feeder accessory for a copying machine, comprising:

sub-member including projecting means for guiding a paper tray into alignment with a copying machine;

means attached to said sub-member, for enabling said sub-member to pivotally engage the copying machine;

a lever mounted on the underside of said sub-member; and

means attached to the copying machine, for engaging said lever and thus maintaining said sub-member in a horizontal position or in one of a plurality of positions oblique to said horizontal position.

5. The paper feeder for a copying machine as claimed in claim 4, wherein said engaging means comprises at least two slots formed in periphery of said engaging means.

6. The paper feeder for a copying machine as claimed in claim 4, further comprised of a paper guide curved toward a register roller, so that the papers are smoothly fed to the register roller when the paper tray is loaded at upper portion of the copying machine.
