うという問題が発生してしまった。However, in such a conventional ADF sheet feeding mechanism 51, in order to prevent the drive shaft 52 from being eccentric, the diameter of the bearing 56 and the opening 58 are required.
It is necessary to make the opening diameter of a substantially the same so that no backlash occurs, and the bearing 56 has to be inserted into the opening 58a with the drive shaft 52 in an oblique state. It has become troublesome. For this reason, the paper feed mechanism
The work of attaching the 51 to the main body 58 becomes troublesome, and as a result, the problem that the workability of the maintenance work deteriorates has occurred.

る。Further, since the diameter of the bearing 56 and the opening diameter of the opening 58a need to be substantially the same, burrs are generated on the inner peripheral surface of the opening 58a and the outer peripheral surface of the bearing 56 as the bearing is inserted and removed. To do that, the work of inserting the bearing 56 becomes more troublesome,
Even if a device for suppressing this burr is taken, it is basically insufficient to improve the operation of inserting the bearing. Therefore, the present invention provides an automatic document feeder that can easily insert a bearing member into an opening, can easily attach a paper feeding unit to a main body, and can improve workability of maintenance work. It is intended to provide a paper feeding mechanism.

In order to solve the above-mentioned problem, the automatic document feeder is arranged above a document conveying path, a driving force is transmitted by a drive shaft, and a sheet bundle placed on a document placing table is fed to form a document. A sheet feeding mechanism for separating the uppermost document from the document bundle together with a separating member provided on the main body side of the transport device, wherein the drive shaft is slid in the axial direction with respect to the main body, In the paper feed mechanism of the automatic document feeder detachably attached to the main body, at least one end of the drive shaft is provided so as to be movable along the drive shaft, and can be engaged with an opening formed in the main body. A bearing member, and a biasing member mounted on the drive shaft for biasing the bearing member outwardly from one end of the drive shaft, wherein the distal end of the bearing member is larger than the opening diameter of the opening. While reducing the diameter,
A flange portion is provided at the base end to abut against the inner peripheral surface of the main body, and when the bearing member is inserted into the opening, the outer peripheral end surface A and the outer peripheral end surface A of the flange portion abut against the inner peripheral surface of the main body. A straight line C connecting the outer periphery B of the opening farthest from
, And the distal end of the bearing member is located within a range of an arc D centered on the outer peripheral end face A with a radius as a radius.

Further, when the bearing member is inserted into the opening, the outer circumference is defined by a straight line C connecting the outer peripheral end face A of the flange portion in contact with the inner peripheral surface of the main body and the outer peripheral portion B of the opening farthest from the outer peripheral end face A. Because the distal end of the bearing member is located within the range of the arc D centered on the end face A, that is, the smaller the amount of penetration of the bearing member into the opening and the larger the flange portion, the more the bearing member is opened. Since the bearing member does not get caught in the opening, it is possible to prevent the bearing member from being caught in the opening when the bearing member is inserted into the opening with the drive shaft inclined.
