録請求の範囲第１項記載の給紙機構。[Claims for Utility Model Registration] (1) It has a sheet loading table on which the copy paper to be fed is placed, and the sheet loading direction side of the sheet loading table is positioned upward by an elastic member provided on the bottom wall. A paper cassette to regulate,
A copy paper feeding mechanism comprising a mounting portion provided on a copying machine main body for accommodating the paper feed cassette and a paper feed roller for feeding copy paper along a predetermined conveyance path. An abutment piece is provided on the outer side wall of the cassette, and the mounting portion includes: (1) a rotatable long shaft extending across the paper feeding direction; (11) a contact piece provided on the long shaft via a support arm; at least one auxiliary roller that revolves around the long axis in conjunction with the rotation of the long axis; (iii) a step portion that is provided at the end of the long shaft and rotates in conjunction with the rotation of the long axis cam, (Ii
i+) a rotatable lever located close to the cam and extending vertically; when the copy paper cassette is removed, the auxiliary roller is suspended from the longitudinal axis and is at its maximum position; When the copy paper cassette is installed in the mounting section, the auxiliary roller contacts and presses the cassette or the stacked copy papers in the cassette, thereby preventing the insertion of the cassette. The cam rotates with the rotation of the long axis, and then the step part of the cam and the upper end of the lever engage, stopping the rotation of the cam, and the rotation of the long axis and assisting. The revolution of the roller has stopped, and the copy paper cassette is inserted in this state, that is, with the auxiliary roller being held at a constant height, and then the abutment piece and the lower part of the lever come into contact and the lever is moved. By rotating, the engagement of the cam with the step part is released, and the auxiliary roller becomes able to revolve again, and the subsequent copying,
When the paper cassette is inserted, the stacked copy paper rises due to the elastic force of the elastic member, and at the same time, the auxiliary roller moves upward due to revolution, and finally the copy paper and paper feed roller come into contact with each other in a positional relationship. A paper feeding mechanism for copy paper, characterized in that these members are provided, and the surface of the auxiliary roller is made of a material with a small coefficient of friction. (2) The paper feeding mechanism according to claim 1, wherein the material having a small coefficient of friction is plastic. (3) A long hole is provided in the sheet loading table, and an operating piece is provided at one end of the long shaft so as to be interlocked with the rotation of the long shaft, so that when the sheet feeding cassette is installed in the mounting section, copying is performed. When the paper runs out, the auxiliary roller falls into the elongated hole and hangs down, and the actuating piece rotates together with the elongated hole, engages with the switch that constitutes the detection mechanism, and operates the switch. The paper feeding mechanism according to claim 1 of the claimed utility model registration function.
