Sheet feeding mechanism and adaptable automatic paper feeder

Abstract

The invention relates to a paper supplying mechanism which comprises a paper fetching part used for contacting and taking away the paper, a bearing device which is used for driving the paper fetching part to lift and provided with a lateral side comprising a top resisting part and a paper blocking mechanism which is connected with a shell body and provided with a baffle and a transmission member that contacts the top resisting part and is connected with the baffle and used for causing the baffle to displace vertically to a paper supplying position and a file paper position; the file paper position limits the front end of the paper, and the paper supplying position lead the paper delivered by the paper fetching part to go through; when the bearing 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 file paper 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 modern times with advanced technology, it is very common for an office 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 it is developing towards miniaturization and functional integration. The multi-functional business machine came into being, which greatly reduces the occupation of space and improves work efficiency. [0003] However, no matter whether it is a single-function business machine or a multi-function business machine, an automatic paper feeding device is required to transmit the paper to the image processing mechanism in the business machine for faxing, printing, etc. The structure diagram of the paper device, as shown in the fig...

[0010] But when the image processing mechanism 19 prepares to provide the double-sided image of the paper 141, the paper 141 that has been conveyed to the contact glass 191 and has been extracted by the image processing mechanism 19 is reversed in the reversing mechanism 121, and sent again. To the contact glass 191, so that the image processing mechanism 19 can perform the function of extracting the double-sided image of the paper 141. At this time, the control circuit of the business machine will issue an instruction to drive the motor to drive the rotating shaft 181 to rotate, so that the paper stopper 183 is rotated to the lowest position. , so that the paper 141 on the paper feeding tray 14 can enter into the automatic paper feeding device 10, however, because the paper 141 to extract the image at this time does not come from the paper feeding tray 14, but is sent to the reversing mechanism 121 for turning the paper 141 At this time, the operation of the motor to drive the rotating shaft 181 to move the paper retaining plate 183 is superfluous, and in order to keep the paper retaining plate 183 fixed in place, the idling state formed by the motor will cause a high loss rate of the motor. The motor needs to be replaced frequently. As we all know, the high price of the motor and the sensor used together will increase the production cost. In addition, the paper 141 on the paper feeding tray 14 will slide forward if the paper stopper 183 is not in contact with the paper 141. Will affect the positioning accuracy of the next feeding

[0011] In addition, the paper stop mechanism 18 can indeed achieve the purpose of driving the clamping part 182 to rotate through the rotating shaft 181, but when the rotating shaft 181 itself rotates, a resistance will be generated, which will additionally increase the burden on the operation of the system
