[0019] image 3 It is a schematic diagram of the first preferred embodiment of the paper picking module of the present invention. The paper pickup module 100 includes a paper holder 10 , a roll paper roller 20 , a first cam 30 , a second cam 40 , a first elastic member 50 , a first chute 60 and a second chute 70 . The paper holder 10 is used to carry the paper 7 for printing. The roll paper roller 20 is provided above the paper holder 10 and is in contact with the paper 7 for printing. The driving device 8 drives the roll paper roller 20 to rotate through the rotating shaft 5 . Both the first cam 30 and the second cam 40 are disposed above the paper holder 10 , and the second cam 40 is disposed adjacent to the first cam 30 . The first cam 30 is driven by the driving device 8 to rotate around the rotating shaft 5 , and the second cam 40 and the rotating shaft 5 can rotate relative to each other. Therefore, the second cam 40 is driven by the first cam 30 to rotate around the ...

[0027] The second preferred embodiment of the paper picking module of the present invention is as follows: 11A to 11D shown. The paper pick-up module 100 includes a paper holder 10, a roll paper roller 20, a first cam 30, a second cam 40, and a first elastic member 50. The structure, function and mutual relationship of each component are substantially the same as those in the first embodiment, so the same The components are denoted by the same reference numerals. However, the relative positions of the first cam 30 and the second cam 40 in this embodiment are different, that is, the first cam 30 is on the inside and the second cam 40 is on the outside. Notches 12 are formed in the side walls to provide space for the first cam 30 to rotate, while flanges 18 extend from the edge of the paper holder 10 . In this embodiment, an opening slot 90 is further included. The opening slot 90 is formed in the notch 12 and is located on the flange 18. When the first cam 30 rotates, the pa...

Abstract

This invention discloses a paper taking module including a paper-backer, a rolling trolley, a first elastic component, a first cam, a second cam and a second elastic component, in which, the paper-backer is used in loading paper, the rolling trolley is set above the paper-backer for rolling paper driven by the shaft, the first elastic component biases the paper-backer upward to make the paper contact to the rolling trolley, the first cam can be set above the paper-backer rotationally to drive it to move up and down with the help of the contact or separation with the backer so as to let the rolling trolley separate from or contact with the paper, the second cam can rotate around a same shaft, the second elastic component is set between the two cams to surround a same shaft and bias the second cam.

Description

technical field [0001] The invention relates to a paper picking module of a printer, in particular to a paper picking module of a printer with low noise. Background technique [0002] The paper picker for existing printers is as disclosed in US Pat. No. 6,293,537. figure 1 and figure 2 The actions of the paper feeder of the existing printer are shown respectively, wherein the paper feeder 116 carries the paper for printing, and the roll paper roller 111 and the cam 112b rotate with the rotating shaft 112a. After the paper is scrolled and conveyed to the left of the drawing, the cam 112b contacts and pushes the projection 115 on the paper holder 116 , and presses the paper holder 116 downward to separate the paper from the roll paper roller 111 . A spring 117 biased against the bump 115 is provided below the bump 115 . When the cam 112b is released from the bump 115 , the paper holder 116 moves upward with the help of the restoring force of the spring 117 to make the paper...
