Title:
AUTOMATIC PAPER FEEDING DEVICE AND FRAME CONSTRUCTION FOR A DOCUMENT INPUTTING DEVICE
Document Type and Number:
WIPO Patent Application WO/1995/018055
Kind Code:
A1
Abstract:
An automatic paper feeding device for a document inputting device includes a pick roller (20), separating pads (68) each adapted to be brought into contact with the pick roller (20), a first pair of pick springs (58) and a pick spring (60). The first pair of pick springs (58) are disposed upstream the second pick spring (60) when viewed in a direction in which paper is carried. The first pair of pick springs (58) are disposed in areas widthwise outside the separating pads (68) in the axial direction of the roller, and the second pick spring (60) is disposed at the widthwise central position between the separating pads (68). The first and second pick springs (58, 60) are formed from a metal sheet integrally with each other as a spring unit, and the contact force of the first pair of pick springs (58) disposed upstream with the pick roller (20) is made smaller than that of the second pick spring (60) disposed downstream. The separating pads (68) are formed as a pad unit by branching a web (70) of a rubber sheet into a fork shape. The spring unit and the pad unit are supported together by means of a bracket (76) and presser member (78).
