The specific embodiment
Fig. 1 shows the schematic side view of the paper feeding equipment of preferred embodiment according to the present invention.Fig. 2 shows the local front-view schematic diagram of the paper feeding equipment of preferred embodiment according to the present invention.The partial schematic diagram of the gear assembly of Fig. 3 displayed map 2.Shown in Fig. 1 to 3, the paper feeding equipment 1 of present embodiment comprises housing 10, rotating shaft 20, gear assembly 30 and roller 40.In addition, paper feeding equipment 1 can also comprise second rotating shaft 20 ', second roller 40 ', rotating shaft 60 and 60 ', passive roller 70 and 70 ', belt 80 and driven wheel 90.
Rotating shaft 20 is arranged on the housing 10 rotationally.Rotating shaft 20 has first end 22 and the second end 24.First end 22 is mounted to first supporting part 12, and the second end 24 is mounted to second supporting part 14.In like manner, rotating shaft 20 ' also is arranged on the housing 10 in a similar fashion and rotationally.
In addition, paper feeding equipment 1 can also comprise scan module 50 and/or 50 '.Scan module 50 and 50 ' is arranged in the housing 10, in order to capture the two-sided image of the paper S that is presented by roller 40.
As shown in Figure 2, the first end 22 of rotating shaft 20 is made up of coaxial minor diameter part 22A and large-diameter portion 22B.The diameter of minor diameter part 22A is less than the diameter of large-diameter portion 22B, and minor diameter part 22A penetrates among the hole 12A of first supporting part 12.So, can limit moving axially of rotating shaft 20, get loose to avoid rotating shaft 20.The both ends 22,24 of rotating shaft 20 can be inserted the first hole 12A respectively and are positioned at the second hole 14A of second supporting part 14.The second end 24 runs through the second hole 14A.
As shown in Figure 3, gear assembly 30 inserts the second hole 14A of second supporting part 14 from the outside of housing 10, and the elastic clamping hook 341,342 of the connecting portion 34 of gear assembly 30 runs through the second hole 14A and is buckled on second supporting part 14.The outer rim 34A of the connecting portion 34 of gear assembly 30 is against the inwall 14B of the second hole 14A of second supporting part 14.
The surface 31 in the face of housing 10 of gear assembly 30 has a plurality of protuberance 31A, is used for contacting with housing 10, so that reduce the friction force that is produced when gear assembly 30 contacts with housing 10.
Fig. 4 shows along the section-drawing of the line 4-4 of Fig. 3.As shown in Figure 4, hollow body 32E has D shape hole 32D.The second end 24 of rotating shaft 20 has D tee section 24D, and itself and D shape hole 32D are suitable, so that gear assembly 30 is fixed in the rotating shaft 20, and rotating shaft 20 can be driven by gear assembly 30.In addition, also can use check screw (set screw) or alternate manner that gear assembly 30 is fixed to rotating shaft 20.By means of above design, rotating shaft 20 both can be fixed on the housing 10, driven by gear assembly 30 and rotated.
The function mode of paper feeding equipment of the present invention will be described below.The driven wheel 90 that is fixed to the motor (not shown) is through 30 rotations of the 32B of tooth portion driven gear assembly, and gear assembly 30 drives belt 80 and the 32A ' of tooth portion rotation through the 32A of tooth portion.Therefore, roller 40 and 40 ' is able to drive passive roller 70 and 70 ' rotation synchronously, so that paper S is presented the scanning area through scan module 50 and 50 ', makes scan module 50 and 50 ' can capture the image of paper S.
By means of paper feeding equipment of the present invention, can under the situation that does not need serviceable tool, directly utilize gear assembly that rotating shaft is arranged at housing rotationally, and the connecting portion of gear assembly can have the function of bearing concurrently.Therefore, compared with prior art, can omit parts such as E shape ring and bearing, and rotating shaft does not need to form annular ditch groove through turning.In addition, the degree of precision that cooperates of the assembled axis hole after intact of gear assembly can reach the grade of prior art.Moreover the dismounting of gear assembly does not need instrument yet, it is drawn close can withdraw from gear assembly as long as the user pushes two elastic clamping hooks.Therefore, gear assembly of the present invention has fast and the not advantage of loss of accuracy of assembling, and the advantage of saving in material and tooling cost.
The specific embodiment that in the detailed description of preferred embodiment, is proposed only is used for convenient explanation technology contents of the present invention; But not with narrow sense of the present invention be confined to the foregoing description; Under the situation that does not exceed spirit of the present invention and following claims; The many variations of being made is implemented, and all belongs to scope of the present invention.
