The present invention also provides a kind of automatic paper feeding equipment, and it comprises supply paper box, paper-feeding channel, paper feed mechanism and paper feed mechanism.The supply paper box is in order to deposit paper.Paper-feeding channel is connected to the supply paper box.Paper feed mechanism is in order to enter paper-feeding channel with paper feeding.Paper feed mechanism goes out paper-feeding channel in order to the paper feeding that will enter paper-feeding channel.Paper feed mechanism comprises first body, second body and barrier element.First roller is installed on first body, and first roller is positioned at the inlet of paper-feeding channel.Second body is articulated in first body, and second roller is installed on second body.Barrier element is articulated in first body, and is subjected to the second body direct drive.Barrier element is between the inlet and supply paper box of paper-feeding channel.When second body rotated into first state with respect to first body, barrier element rotated into closed condition with respect to first body, moved to the inlet of paper-feeding channel to stop paper.When second body rotated into second state with respect to first body, barrier element rotated into opening with respect to first body, moved to the inlet of paper-feeding channel to allow paper.
For foregoing of the present invention can be become apparent, preferred embodiment cited below particularly, and cooperate appended graphicly, be described in detail below.
Description of drawings
Fig. 1 shows the scheme drawing according to the automatic paper feeding equipment of preferred embodiment of the present invention.
Fig. 2 to 4 shows the scheme drawing according to three kinds of operating states of the paper feed mechanism of the first embodiment of the present invention.
Fig. 5 and 6 shows the schematic perspective view according to two kinds of operating states of the paper feed mechanism of the second embodiment of the present invention.
The specific embodiment
Fig. 1 shows the scheme drawing according to the automatic paper feeding equipment of preferred embodiment of the present invention.Fig. 2 to 4 shows the scheme drawing according to three kinds of operating states of the paper feed mechanism of the first embodiment of the present invention.
At first, as shown in Figure 1, the automatic paper feeding equipment of present embodiment comprises supply paper box 10, paper-feeding channel 20, paper feed mechanism 30 and paper feed mechanism 40.In addition, this automatic paper feeding equipment can further comprise friction pad 50.Moreover this automatic paper feeding equipment can be a file scanner, so it further comprises scan module 60.
10 one-tenth horizontal or level of approximation shapes of supply paper box are opened in order to deposit paper S or plurality of sheets of paper.Paper-feeding channel 20 is formed in the housing 70 of automatic paper feeding equipment, and is connected to supply paper box 10.
Paper feed mechanism 40 is presented out paper-feeding channel 20 in order to the paper S that will enter paper-feeding channel 20.In the present embodiment, paper feed mechanism 40 comprises a pair roller 41 and 42 and another pair roller 43 and 44.
In order to reach suitable retaining paper function and effectiveness, paper feed mechanism 30 is designed to have following feature.
When second body 33 rotates into first state with respect to first body 31, barrier element 35 rotates into closed condition with respect to first body 31, to stop paper S to move to the inlet 21 of paper-feeding channel 20, just stop paper S to move to the paper feed device PI that contacts with first roller 32, as shown in Figure 2.That is to say that when second roller 34 was lifted, barrier element 35 must stop that paper enters this inlet 21.
When second body 33 rotates into second state with respect to first body 31, barrier element 35 rotates into opening with respect to first body 31, to allow paper S to move to the inlet 21 of paper-feeding channel 20, just allow paper S to move to the paper feed device PI that contacts with first roller 32, as shown in Figure 4.That is to say that when second roller 34 fell, barrier element 35 did not stop that paper enters this inlet 21.
Specifically, shown in Fig. 2 to 4, second body 33 has guide groove 331, and an end of barrier element 35 inserts in the guide groove 331, and thus, barrier element 35 can rotate along with second body 33.Guide groove 331 is for being formed on the groove on second body 33.
In addition, barrier element 35 comprises stopper section 35A and forced section 35B.The end of forced section 35B inserts in the guide groove 331.As shown in Figure 2, forced section 35B sees through guide groove 331 and second body 33 links, driven and turned to primary importance by second body 33, and make stopper section 35A turn to restriction site and enter closed condition, stopper section 35A stops paper S to move to the inlet 21 of paper-feeding channel 20.As shown in Figure 4, forced section 35B is driven by second body 33 and turns to the second place, makes stopper section 35A turn to retracted position and enters opening, moves to the inlet 21 of paper-feeding channel 20 to allow paper S.In the present embodiment, when stopper section 35A turned to restriction site, stopper section 35A was erectility; When stopper section 35A turned to retracted position, stopper section 35A was the level of state, and the passage between the inlet 21 of supplying paper box 10 and paper-feeding channel 20 is kept clear.
When second body 33 was between first state and second state, the state of barrier element 35 as shown in Figure 3.
Fig. 5 and 6 shows the schematic perspective view according to two kinds of operating states of the paper feed mechanism of the second embodiment of the present invention.Shown in Fig. 5 and 6, first body 31 and second body 33 respectively comprise framework.First body 31 is made of outside frame 31A and central support 31B.
Therefore, except aforesaid automatic paper feeding equipment was provided, the present invention also provided a kind of paper feed mechanism 30, and it comprises first body 31, second body 33 and barrier element 35.First roller 32 is installed on first body 31.Second body 33 is articulated in first body 31.Second roller 34 is installed on second body 33.Barrier element 35 is articulated in first body 31, and is subjected to second body, 33 direct drives.When second body 33 rotated into first state with respect to first body 31, barrier element 35 rotated into closed condition with respect to first body 31, moved to the paper feed device PI that contacts with first roller 32 to stop paper S.When second body 33 rotated into second state with respect to first body 31, barrier element 35 rotated into opening with respect to first body 31, moved to the paper feed device PI that contacts with first roller 32 to allow paper S.
By the above embodiment of the present invention, can utilize simple mechanism and less part to reach the function of in good time retaining paper.Because employed part is few and mechanism design is simple, therefore can reduces manufacturing cost and make dismounting, replacing and the installation of pickup roller be able to judicial convenience.In addition, barrier element 35 can be arranged on the position of more pressing close to comber, with the gap between the minimizing paper, thereby can effectively promote scanning speed (number of pages of per minute).
The specific embodiment that is proposed in the detailed description of preferred embodiment is only in order to convenient explanation technology contents of the present invention, but not with narrow sense of the present invention be limited in the foregoing description, under the situation that does not exceed spirit of the present invention and appending claims institute restricted portion, the many variations of being done is implemented, and all belongs to scope of the present invention.
