Embodiment Construction

[0024] Embodiments of the present invention are described below with reference to the drawings.

[0025] figure 1 It is a side cross-sectional view of the internal structure of the image forming apparatus 100 equipped with the coupling mechanism according to the embodiment of the present invention. In addition, the solid line arrows in the figure indicate the transport path and transport direction of the paper.

[0026] exist figure 1 In the image forming apparatus 100, a cassette type paper feeding unit 101 is disposed below the image forming apparatus 100. The cassette-type sheet feeding unit 101 includes a plurality (here, three) of sheet feeding cassettes (sheet storage cassettes) 1 . Sheets (sheets) P ​​such as cut sheets before printing are stacked and accommodated inside the paper feed cassette 1, and are separated one by one by a paper feed mechanism 117 composed of a pickup roller 113 and a pair of paper feed rollers 115. paper P, and paper P is ejected.

Abstract

A coupling mechanism of the present disclosure includes a drive transmission member, a coupling member and a biasing member. The drive transmission member includes a shaft portion and an engagement pin. The coupling member includes a plurality of engagement protrusions and a holding protrusion which is smaller than the engagement protrusion. The holding protrusion makes contact with the engagement pin in a state where the engagement pin makes contact with the pressing surface. A load in a reverse rotation direction is applied from the holding protrusion to the engagement pin when the coupling member is reversely rotated.

Description

technical field [0001] The present invention relates to a coupling mechanism and a sheet feeding device and an image forming apparatus provided with the coupling mechanism, and in particular, to a coupling mechanism having a drive transmission member fixing a driven member and a coupling member engaged with the drive transmission member, and the coupling mechanism having the same sheet feeding device and image forming device. Background technique [0002] Paper feeding cassettes (sheet storage cassettes) are used for feeding cut sheets and the like in image forming apparatuses typified by copiers and printers. This paper feeding cassette stores a plurality of sheets of paper before printing, and the paper feeding roller and pickup roller, etc. arranged near the paper feeding cassette are used to print paper one by one from the top layer of the stack of paper stacked in the paper feeding cassette. Separate the paper and supply. [0003] In addition, the sheet feeding casset...
