Embodiment Construction

[0031] Examples of the present invention will be described below with reference to these drawings.

[0032] exist figure 1 An image forming apparatus 1 according to an example of the present invention is shown in . This image forming apparatus 1 has various functions, such as a facsimile function, a printing function, a copying function, and a scanning function, so as to function as a multifunction device (MFD). The image forming apparatus 1 includes: a substantially box-shaped main body casing 2 opened at its upper portion; and an upper casing 3 which is pivotally mounted on the main body casing 2 so as to rotate vertically around a rotation shaft (not shown). , the rotation axis is constituted by a hinge provided at the rear side along the rear surface of the main body casing 2 .

[0033] In the description here, the near side (the side facing the user) of the imaging apparatus 1 is determined as the front side. The left-right direction (main scanning direction or Y-axis ...

Abstract

A sheet feeding device includes: an arm member that is provided with a drive shaft at a base end thereof, the arm member being configured to swingably rotate around the drive shaft; a feed roller thatis disposed at a leading end of the arm member, the feed roller feeding a sheet by being rotated while pressed on the uppermost sheet; and a transmission mechanism that is provided with one or more transmission rollers that transmit power provided from the drive shaft to the feed roller. Each of the transmission rollers is provided with a spindle that protrudes from both side faces thereof alongan rotational axis. The arm member is provided with one or more pairs of bearing members for the respective transmission rollers, each of the pairs of the bearing members being faced with each other and being monolithically formed on the arm member.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Japanese Patent Application No. 2006-044874 filed on February 22, 2006. The entire subject matter of that application is hereby incorporated by reference. technical field [0003] The present invention relates to a paper feeding device that feeds cut paper or synthetic resin sheets (hereinafter simply referred to as paper) one by one, and an image forming apparatus having the same. Background technique [0004] In general, there is known a paper feeding device having a paper feeding roller that feeds paper to an image forming portion of an image forming apparatus such as an inkjet printer, the paper feeding roller being provided at a front end portion of an arm having The bottom end portion is rotatably supported by the main body of the image forming apparatus. [0005] In the paper feeding device thus constituted, the paper feeding roller is pressed against the uppermost sheet o...
