The specific embodiment
Please with reference to Fig. 2 and Fig. 3 by the present invention the paper delivery mechanism of paper carrier of exposure first embodiment.
The paper delivery mechanism 1 of paper carrier comprises: pedestal 11, adapter shaft 12, paper feed roller 14, elastic parts 16.
The seat body 11 is substantially a hollow receiving body, the bottom of the curved plate, a second side wall surface 111 extend respectively, Bing provided on the side wall surface 111 of the receiving hole 112, and wherein the side wall 111 of the a positioning hole 113.
Set the paper feed rollers 14 located on the connecting shaft 12, in this embodiment, the primary paper feed rollers 14 by the shaft portion 141 and the ring portion 142, of which the wheel portion 142 may be made of rubber or plastic, Bing cap provided on the shaft portion 141, to transfer files 8.In addition, axial region 141 preferably can be made up of the primary shaft 1411 that links to each other and second 1412, and wherein, wheel portion 142 is sheathed on the primary shaft 1411, and the external diameter of primary shaft 1411 preferably can be greater than second 1412 external diameter.At this, the structure of paper feed roller 14 is merely for example, and the present invention is non-as limit.
See also shown in Figure 4, when power wheel 6 rotates, if file 8 through the time, paper feed roller 14 can be along with power wheel 6 rotates together; When file 8 passes through; Because of the friction force of power wheel 6 is bigger, so can driving files 8, power wheel 6 advances, if when having file 8 more than two to pass through; Power wheel 6 only can drive uppermost file 8 and advance, and remaining file 8 can be stopped and slack by paper feed roller 14.
In the present embodiment; Paper feed roller 14 is sheathed on adapter shaft, and an end of elastic parts 16 directly is positioned paper feed roller 14, and the other end is directly connected in pedestal 11; Therefore can more existing paper delivery structure decrease spare part quantity, effectively reduce the manufacturing cost and the assembly cost thereof of spare part.
Please with reference to Fig. 5 and Fig. 6 by the present invention the paper delivery mechanism of paper carrier of exposure second embodiment.Not existing together of the present embodiment and first embodiment is the structure of paper feed roller 14.In the present embodiment, paper feed roller 14 mainly can be made up of with 142 in wheel portion adapter shaft 144, wherein; The body of rod that adapter shaft 144 is roughly elongated, by its norma lateralis it, the transversal surface of adapter shaft 144 is semicircular in shape roughly; And two ends of adapter shaft 144 are arranged in respectively in the containing hole 112 of pedestal 11, and adapter shaft 144 has by primary shaft 1441 and second 1442 axial region of being formed of linking to each other, wherein; Wheel portion 142 is sheathed on the primary shaft 1441, in order to transmit file 8; Elastic parts 16 is sheathed on second 1442, and an end of elastic parts 16 embeds knock hole 113, and the other end is held in primary shaft 1441.At this, the external diameter of primary shaft 1441 preferably can be greater than second 1442 external diameter.
The maximum difference of the present embodiment and first embodiment is: the adapter shaft of first embodiment and paper feed roller are independently two spare parts of difference; Present embodiment then is integrated into a spare part with adapter shaft and paper feed roller, so its spare part quantity is few than first embodiment again.In addition, the adapter shaft of first embodiment has diagonal plane, so the diagonal plane of its adapter shaft is fastened in the wall of containing hole, makes paper feed roller adapter shaft when rotating or not; The paper feed roller of present embodiment is provided with the structure of adapter shaft, so its adapter shaft structure can be rotated along with the wheel portion of paper feed roller.
The present invention can be provided in the paper feed roller sleeve connecting shaft, or to the paper feed roller is formed integrally with the connecting shaft, and the elastic member sleeved on the paper feed roller, and the end of the paper feed roller is positioned directly at the other end directly connected to the seat body, compared with the existing structure of the paper, the present invention is not required a copper sleeve, cover and other components, therefore, the present invention is the structure of the paper than the existing structure is simple, the number of components less than the structure of the paper, not only can significantly reduce the manufacturing cost of components, the assembly cost can be reduced Bing Moreover, by reducing the number of components to simplify the assembly process, while providing effective assembling work efficiency and yield.
Though technology contents of the present invention discloses as above with preferred embodiment; Yet it is not in order to limit the present invention; Anyly be familiar with this operator; Under the prerequisite that does not break away from spirit of the present invention, can make all changes that is equal to or replacement, change that these are equal to or replacement all should be covered by in the category of the present invention, so protection scope of the present invention is when looking accompanying being as the criterion that the application's claim scope defined.
