Sheet feeding mechanism and adaptable automatic paper feeder

Abstract

The invention relates to a paper supplying mechanism which comprises a paper fetching part, a carrying device provided with a top resisting part at the lateral side; and a paper blocking mechanism which is connected with a shell body and provided with a baffle and a transmission member, the transmission member provided with a holding part contacted with the top resisting part, a contact part for holding the baffle and a shaft arranged at an extension and connection position of the holding part and the contact part; wherein the both sides of the shaft is held by holding arms of the shell body so that the paper blocking mechanism is connected and hung on the shell body, the transmission member is used for vertically displacing the baffle to a paper supplying position which enables papers discharged from the paper fetching part to pass and a paper blocking position which limits front end of papers, when the carrying device and the paper fetching part rotate downwards, the top resisting part drives the transmission member to drive the baffle to displace to the paper supplying position; when the bearing device and the paper fetching part rotate upwards, the transmission member displaces with the rotation of the top resisting part and the effect of gravity so as to drive the baffle to move to the paper blocking position.

Description

technical field

[0001] The invention relates to a paper feeding mechanism, in particular to a paper feeding mechanism suitable for an automatic paper feeding device. Background technique

[0002] In the modern age of advanced technology, it is very common for offices to have multiple business machines with different functions, such as copiers, fax machines, scanners, etc. However, too many business opportunities occupy too much space in the office, so the development of miniaturization and functional integration develops The multifunctional business machine came into being, which greatly reduced the space occupation and improved work efficiency.

[0003] However, whether it is a single-function MFP or a multi-function MFP, an automatic paper feeding device needs to be set to transmit the paper to the image processing mechanism in the MFP for processing such as faxing and printing. Please refer to FIG. 1a, which is a well-known automatic feeder. A schematic diagram of the st...
