technical field

The invention relates to an automatic paper feeding device of electronic equipment and electronic equipment, in particular to an automatic paper feeding device with a paper blocking mechanism and electronic equipment with the automatic paper feeding device. the

Background technique

Generally, the automatic paper feeding devices of electronic equipment such as photocopiers, fax machines or multi-functional office machines usually have a paper stop mechanism on the inside of the paper support tray to limit the amount of paper placed on the paper support tray along the paper feeding path. The position enables the user to quickly and neatly place the paper in an appropriate position on the paper tray to reduce skew or paper jams during paper conveyance, thereby improving the stability of the paper conveyed by the automatic paper feeder. the

Please refer to Fig. 1, Fig. 2 and Fig. 3. Fig. 1 and Fig. 2 are side views of the automatic paper feeding device of general electronic equipment. The top view on the paper feeding wheel shaft shows an automatic paper feeding device 1 of an electronic device 100 disclosed in US Patent No. 6,893,013B2. The automatic paper feeding device 1 includes a paper support tray 11, a paper feeding wheel set 12 and a paper blocking mechanism 13; the paper feeding wheel shaft 121 of the paper feeding wheel set 12 is sleeved with two paper feeding wheels 122, 123, A compression spring 131, a sleeve ring 132 and a driven arm 133 of the paper stop mechanism 13 are respectively sleeved on the paper feed wheel shaft 121 and are located between the two paper feed wheels 122, 123. Connected to the feed wheel 123 and the compression spring 131 , an axial force of the compression spring 131 generates a frictional moment that drives the driven arm 133 to rotate, so that the follower arm 133 can rotate along with the feed wheel shaft 121 . the

When the paper feeding wheel shaft 121 rotates counterclockwise in the direction indicated by the arrow in FIG. The first sheet 135 of the paper stopper 134 abuts against it, while the second sheet 136 of the paper stopper 134 protrudes from the inner end 111 of the paper support tray 11 to limit the paper (not shown) from the paper support tray 11. The outer end 112 of the outer end 112 is inserted into the paper support tray 11 along the paper feeding path and continues to move forward. When the paper picking mechanism (not shown) of the automatic paper feeding device 1 intends to pick up paper, the paper feeding wheel shaft 121 rotates clockwise in the direction shown by the arrow in FIG. At the position where the sheets 135 abut against each other, the paper blocking member 134 pivots due to its own weight so that the second sheet 136 is aligned with a screen wall 14 , and the paper can pass along the paper feeding path at this time. the

Since the compression spring 131, the collar 132 and the follower arm 133 of the paper stop mechanism 13 are all sleeved on the paper feed wheel shaft 121 and located between the two paper feed wheels 122, 123, the assembly steps between the various components are relatively complicated. , and because the paper feed wheel shaft 121 is arranged on the inside of the movement below the paper tray 11, it is not easy to replace if each component is damaged or defective. In addition, since the power source of the driven arm 133 of the paper stop mechanism 13 when it rotates comes from the paper feed wheel shaft 121, the driven arm 133 needs to pass through the inside of the machine core before it can touch the paper stopper 134 to rotate. Function In terms of the automatic paper feeding device for double-sided scanning, there will be an additional paper feeding path design inside the machine core, and the design method of the paper stop mechanism 13 will increase the difficulty in designing the internal space of the machine core, so the paper stop Mechanism 13 cannot be used on an automatic paper feeder with a double-sided paper feed function. the
