The specific embodiment
Fig. 1 is the scheme drawing of demonstration according to the image capture unit of the scanner of preferred embodiment of the present invention.As shown in Figure 1, the image capture unit of present embodiment comprises housing 1, paper feed mechanism 2 and image acquisition unit 3.Paper feed mechanism 2 is installed on the housing 1, in order to feed paper S.Image acquisition unit 3 is installed in the housing 1, in order to the image on the acquisition paper S.
Fig. 2 is the block diagram that the paper feed mechanism of displayed map 1 is in the flip closure state.Fig. 3 is the block diagram that the paper feed mechanism of displayed map 1 is in the flip opening.As shown in Figure 1 to Figure 3, paper feed mechanism 2 comprises body 10, flip 20, actuator 40, rotating shaft 50, paper feed roller 60, first gear 70, intermediate gear 80 and second gear 90.
Actuator 40 is installed on the pivot 30, and rotating shaft 50 is rotatably installed on body 10.Paper feed roller 60 is installed in the rotating shaft 50, in order to feed paper S.Usually, one or more paper feed rollers 60 can be installed in rotating shaft 50, and one or more roller 62 (referring to Fig. 1) can be worked in coordination and fed paper S with paper feed roller 60.
Under the normal operation state, flip 20 close and rotating hinge 30 to drive intermediate gear 80 engagement second gear 90 and first gears 70.
Getting rid of under the state of paperboard, flip 20 is opened and rotating hinge 30 and activated drive part 40 breaks away from first gear 70 to drive intermediate gear 80.Yet in other embodiments, intermediate gear 80 also can be designed to break away from second gear 90.
In addition, paper feed mechanism 2 can also comprise swing component 95, motor 100, driven wheel 110, the 3rd gear 130, the 4th gear 140, comber axle 160, the 5th gear 150 and comber 170.
Fig. 4 and Fig. 5 are respectively the partial enlarged drawing of the paper feed mechanism of displayed map 2 and Fig. 3, wherein clipped assembly.To shown in Figure 5, swing component 95 is installed on the body 10 rotationally as Fig. 2, and intermediate gear 80 is installed up on the swing component 95 by pin 81.
On the other hand, motor 100 is installed on the body 10, and the outputting power of motor 100 is passed to first gear 70 by second gear 90 and intermediate gear 80.Driven wheel 110 is installed on the output shaft 120 of motor 100.The 3rd gear 130 and driven wheel 110 engagements.The 4th gear 140 and the 3rd gear 130 are coaxial to be arranged on the axle 131, and with 90 engagements of second gear.Comber axle 160 is rotatably installed on body 10.The 5th gear 150 is installed on the comber axle 160, and receives the outputting power from motor 100 by the 3rd gear 130 and several gears (not indicating especially).Comber 170 is installed on the comber axle 160, in order to move to carry out separation with friction pad 180 (please refer to Fig. 1) combined action.
In the present embodiment, actuator 40 comprises elongated slot 41, is inserted into elongated slot 41 and can moves in elongated slot 41 and be arranged on pin 81 on the intermediate gear 80, thereby make intermediate gear 80 be arranged at actuator 40 movably.In addition, body 10 comprises arc groove 11, is inserted into arc groove 11 and can moves in arc groove 11 and sell 81.Swing component 95 and second gear, 90 coaxial being arranged on the axle 91.
The interlock state of flip 20 and actuator 40 below will be described.As Fig. 2 and shown in Figure 4, when flip 20 is covered on the body 10, flip 20 drives actuator 40 toward the anticlockwise direction rotation by pivot 30, and then passes through pin 81, swing component 95 and arc groove 11, and intermediate gear 80 is moved to the position that is meshed with second gear 90 and first gear 70.As Fig. 3 and shown in Figure 5, when flip 20 is raised, flip 20 drives actuator 40 toward right-hand revolution by pivot 30, and then passes through pin 81, swing component 95 and arc groove 11, and intermediate gear 80 is moved to the position that breaks away from second gear 90 and first gear 70.Therefore, can allow the breakdown action of flip 20 force intermediate gear 80 with second gear 90 and 70 engagements of first gear or separate.Therefore, actuator 40 gear of can being known as breaks away from control assembly.
Two kinds of interlocking patterns of Fig. 6 and Fig. 7 display driver spare 40 and pivot 30.As Fig. 6 and shown in Figure 7, actuator 40 comprises protuberance (can be described as first bite again) 42, pivot 30 comprises recess (can be described as second bite again) 32, protuberance 42 and recess 32 interlocks, and gapped G between protuberance 42 and the recess 32, the angle of 10 of flip 20 and bodies so that flip 20 can be extended when opening.Pivot 30 is fixed in the flip 20, supposes that the pivot 30 of Fig. 6 forwards the state that makes flip 20 closures to.Thus, when the user will open flip 20, as shown in Figure 7, pivot 30 must dally an angle toward the clockwise direction to overcome clearance G, could drive actuator 40 and intermediate gear 80 is separated with second gear 90 and first gear 70.This provides a buffering production time, also makes flip 20 be strengthened with respect to the opening angle of body 10 simultaneously.It should be noted that in another example actuator 40 also can comprise recess (being called first bite again), and pivot 30 also can comprise protuberance (being called second bite), can reach above-mentioned effect equally.
By the above embodiment of the present invention, can under the situation of not using extra power, reach the purpose that gear separates, and the separation of gear and engagement are and the flip interlock.Therefore, the fastening power that flip does not need to provide extra come that antagonistic spring provides separating force, and flip does not have closed bad or cause gear to jump the problem of tooth.
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 to the foregoing description, in the situation that does not exceed spirit of the present invention and following claim, the many variations of being done is implemented, and all belongs to scope of the present invention.
